However, the invention is not limited to elevators, but can also be attributed to trapezoidal threaded rods, screw rods, spindle rods, etc., which are used in a large number of industrial segments and areas of use as well as transport areas.
    BACKGROUND Today, threaded rod sections are mounted to each other forming a long threaded rod with one or more threaded grooves. Each threaded rod section comprises at its one end a female portion (hole) with thread and at its other end a male portion (pin) with corresponding thread. A first threaded rod section is thus joined to a second threaded rod section by screwing together. It is important that the threaded rod sections end up in the correct position relative to each other so that the threaded groove or thread grooves do not form a notch or any step in the joint after screwing together (assembly). To ensure that the inputs for the thread grooves of the spliced threaded rod sections end up facing each other and form a smooth transition, the first threaded rod section is provided with a predetermined marking which is to coincide with a marking of the second threaded rod section.
    To adjust the mutual angle of rotation between the threaded rod sections so that the markings coincide with each other to ensure a smooth transition between the threads of the threaded grooves, assembly personnel today use, for example, pipe tongs to tighten the screw joint so that the markings match.
    SUMMARY OF THE INVENTION It is an object to securely and time-savingly mount threaded rod sections to each other, which threaded rod sections extend longitudinally axially along a central axis, while the inputs of two assembled screw rods end up facing each other. between male part and female part.
    A further object is to be able to easily rotate a first threaded rod section relative to a second threaded rod section to a correct mutual angular position. A purpose is to rotatably secure the assembly of a first threaded rod section to a second threaded rod section.
    A further object is to be able to joint with precise precision two threaded rod sections, each having at least one threaded entrance on the outer surface of each threaded rod section.
    Another purpose is that a fitter should be able to mount a screw joint in low light and little visual contact with the screw joint. A further is to avoid damage to the threads of the threaded rod sections during fitting and mounting. A purpose is also to further develop known technology in the field. At least one of the above-mentioned objects has been achieved by means of the rotary measuring device defined in the preamble of the description, characterized by the characterizing part of claim 1. Preferably, the rotary measuring device is a combined rotary measuring and mounting device. Preferably, the first lever portion of the .
    Suitably the first adjusting element comprises an elongate first screw comprising a first grip which can be gripped by a human hand, which first screw partly engages with the second rotating member and partly engages with the first lever portion so that upon rotation of the first grip, the first and second the rotating member can be rotated relative to each other for a mutual angular adjustment. Preferably, the first grip is arranged with a plus mark.
    In this way, an installer can note the number of turns he turns the first grip to achieve a reciprocal rotation of the threaded rod sections clockwise.
    Preferably, the first adjusting element is arranged to provide a traction force and prevented from producing a compressive force so that the first adjusting element can be operated to effect a rotational movement of the first rotating member relative to the second rotating member clockwise.
    In this way, the first rotating member can be rotated relative to the second rotating member about said central axis and by means of the lever portion a simple operation of the rotary measuring device for an installer is achieved.
    In this way a tool has been provided which is easy to use by a fitter and at the same time provides an exact fitting of the screw joint of the first and second threaded rod.
    With the aid of the exact fit, a predetermined preload of the screw joint is achieved.
    Preferably, the threaded rod sections extend longitudinally axially along a central axis.
    Preferably, the first threaded rod section is provided with a joint-facing one-mounting pin (male portion) extending in the direction of the central axis, the mounting pin being provided with an external thread.
    Suitably the second threaded rod section is provided with a joint end having a mounting hole (female portion) extending in the direction of the central axis, the mounting hole having internally a mounting pin corresponding to the thread.
    Preferably, the mounting pin is arranged with a first transverse hole (male portion hole) extending across said central axis.
    Preferably, a portion of one end of the second threaded rod section, which forms saw mounting holes, is provided with a second and third transverse holes (female portion holes), which in turn are aligned with each other. Said second and third transverse holes extend across the central axis of the saw and form said female part hole, which is cut in the transverse direction by said mounting holes.
    Preferably, said mounting pin and said mounting holes comprising mating threads and said first, second and third transverse holes are so defined that when mounting and adjusting mutual angle adjustment a standardized bias is provided in the screw joint while an exact fit is achieved.
    Suitably, said threaded rod section is arranged with at least one threaded groove (for example trapezoidal thread).
    Thus, the joint end of the threaded section of the threaded rod section has an entrance which is to be fitted into an input threaded groove of the corresponding spliced threaded rod.
    Preferably, the position of said threaded entrance of the respective threaded rod section is predetermined in position during manufacture of the threaded rod section so that the respective threaded entrance faces the suitable threaded entrance. At the same time, in the manufacture of the threaded rod sections, the design of disassembly pins (with external thread) and mounting holes (with internal thread) is predetermined, the thread grooves of which show the entry position and thread pitch in such a way that said threaded inputs (at the perimeter surface of the threaded rod sections) predetermined bias is achieved. At the same time, in the manufacture of the threaded rod sections, it is predetermined to take up the first, second and third transverse holes of the male portion and the female portion, which must be in line with each other during said completed assembly.
    Thus, the splice end of the threaded rod section can have several threaded grooves with several inputs, which must face several entrance threaded grooves of the corresponding spliced threaded rod, with great accuracy.
    Preferably, a second adjusting element can be coupled between a second lever portion arranged at the second rotating member and the first rotating member.
    In this way, the second rotating member can be rotated relative to the first rotating member about said longitudinal axis and by means of the lever portion a simple operation is provided for a fitter.
    Suitably the second adjusting element comprises an elongate second screw comprising a second grip which can be gripped by a human hand, which second screw partly engages with the first rotating member, partly engages with the second lever portion so that upon rotation of the second grip the first and second rotating means can be rotated relative to each other for a mutual angle adjustment.
    Preferably, the second grip is set up with a minus mark.
    In this way, a fitter can note the number of turns he turns the second grip to achieve a reciprocal rotation of the threaded rod sections counterclockwise.
    For example, in the case where the fitter rotates the first grip with the plus mark four turns, he turns the second grip two turns (half the number of turns for the first grip).
    Preferably, the second adjusting element is arranged to provide a tensile force and prevented from producing a compressive force so that the second adjusting element can be operated to effect a rotational movement of the first rotating member relative to the second rotating member counterclockwise.
    Preferably, said first adjusting element comprises a first screw in engagement with the second rotating member.
    Suitably the rotary measuring device comprises a measuring pin for mutual angular position between a male portion hole of said first threaded rod and a female portion hole of said second threaded rod.
    In this way, it is ensured that the inputs for the thread grooves of the spliced threaded rod sections end up in the correct position relative to each other and face each other and form a smooth transition.
    Preferably, the male portion and the female portion are provided with one (or at least two) through-matching and reciprocal transverse (across the central axis) through holes (of the male portion and the female portion) which are in line with each other.
    This is achieved by means of the male transverse holes of the male portion and the two transverse holes of the female portion being in line with each other that the screw joint between two threaded rod sections is tightened with a predetermined pretension.
    In this way it is achieved that a predetermined preload in the screw joint prevails during completed assembly-independent tolerance setting of said through-going transverse holes. This is ensured by the continuous and transverse holes being in line with each other.
    Suitably, pipe pins are driven into the through-going and transverse holes to secure the screw joint.
    Preferably, after driving in, the pipe pins have deformations locking the pipe pins at the threaded rod sections.
    Suitably, during deformation, a deformation zone is provided on the mantle surface of the securing pins in the boundary area between mounting pin and mounting hole. In this way a permanent joint is obtained which is secured against undesired rotational movement of the threaded rod sections relative to each other.
    This has also been solved by means of a method for adjusting a mutual angle between a first and a second threaded bar section by means of a rotary measuring device, which in use are engaged first and second threaded rod section, wherein a rotary measuring device associated with first and second rotary members each comprises a first and second gripping means for releasably attaching to said first and second threaded bar sections mounted to each other, a first lever portion of the first rotating member being connectable to the second rotating member by means of a first adjusting element, the method comprising the steps of; engaging said first threaded rod section with the first gripping means; engaging said second threaded rod section with the second gripping means; inserting a first diameter measuring pin through a transverse with a second diameter first male portion hole of said first threaded rod section and a transverse first female portion hole of said second threaded rod section; rotating in a first reciprocal direction of rotation said first and second rotating means at a first mutual angle where the inserted measuring pin prevents further rotation; rotating said first and second rotating means in a second mutual direction of rotation opposite and by half the value of said first reciprocating direction of rotation.
    Said transverse first female portion hole includes the aforementioned second and third transverse holes extending across said central axis. The first female portion hole is cut in the transverse direction of said mounting holes.
    Alternatively, an initial misalignment is accomplished by inserting a dipstick comprising a first portion of truncated conical tip and a second portion having a constant diameter into the first transverse hole and partially into the first transverse hole set.
    For example, the end of the truncated conical tip may end up within the area of the central axis or at a suitable distance from the central axis. Preferably, the first portion has a smaller diameter than the second portion.
    Preferably, the first diameter of the dipstick (at the second portion of the dipstick) is smaller than the second diameter of the transverse holes.
    Suitably, the first female portion hole has a third diameter corresponding to the second diameter or different from the second diameter.
    In this way, a method has been provided which ensures correct splicing between two threaded rods so that the male portion hole and the female portion holes coincide in line with each other.
    This provides a simple operation for connecting two threaded rods at the same time as inputs for the threaded rods' threads end up in front of each other and a predetermined preload is provided in the screw joint.
    Suitably the measuring stick has a first portion which is conically tapered in the direction of a second portion arranged with the measuring stick with a constant (cylindrical) first diameter.
    Preferably, the method prior to the step of inserting the dipstick comprises the step of rotating said first and second threaded rods so that said first male portion holes and first female portion holes form a bushing having a smaller diameter than the diameter of the dipstick (smaller than the second portion diameter and larger than the first portion end and / or smaller than the diameter of a suitable cross-section of the first portion).
    In this way, the measuring stick will be stopped, which means a partial insertion of the measuring stick, whereby said rotation in the first mutual direction of rotation from an original position will start in an exact original position. This is possible because the position where the dipstick from partial insertion is allowed to be pushed completely through the male portion hole and the female portion hole - two female portion holes surrounding and in line with the male portion hole - with its second portion is noted by the fitter.
    Preferably, the step of rotating the threaded rods (by means of the rotating means) in a first mutual direction of rotation forming a first mutual angle (from the initial position to the position where the inserted dipstick further prevents rotation of the first threaded rod section relative to the second threaded rod section) Suitably, the method comprises the subsequent step of, when the first transverse male portion hole and the first female portion hole are aligned with each other, driving a first pipe pin through them to rotatably secure the assembly.
    In this way, a locking of the screw joint is ensured.
    Preferably, the method comprises the step of driving a second pipe pin through a second transverse male portion hole and second transverse female portion holes in line with each other. Preferably, the diameter ratio between a second measuring pin and respective second male portion holes and female portion holes, in the same manner as for the first male portion hole and the second female portion hole relative to the first dipstick.
    Thus, a double locking is achieved, which promotes safety when, for example, operating passenger lifts.
    Suitably, said first mutual direction of rotation is performed clockwise.
    Preferably, said second mutual direction of rotation is performed counterclockwise.
    In order to ensure that the inputs for the thread grooves of the spliced threaded rod sections end up facing each other and form a smooth transition, male and female portions are provided with one or more transverse through holes which are to be in line with each other. When said through holes of the respective male and female portions are in line with each other, the screw joint between two threaded rod sections is tightened with a predetermined preload.
    In order to be able to achieve a predetermined preload in the screw joint, regardless of the tolerance setting of said through holes, the through holes must thus be in line with each other. Pipe pins are driven into the holes to rotate the screw joint, thereby creating a deformation zone on the mantle area. mounting pin and mounting holes. In this way, a permanent joint is obtained which is secured against unwanted torsional movement.

    Fig. 1a shows three threaded screw sections 1 ', 1 ", 1"' for splicing. A first threaded screw section 1 'comprises a first splice end 3' having a first male portion 5 'and a second splice end 3 "having a first female portion 7'. splice end 3 "having a second female portion 7".
    Fig. 1b shows an joined threaded screw 1 for driving an elevator car 9. The threaded screw 1 is fixedly mounted in its upper end 10 and freely suspended with its lower end 11.
    Fig. 2a shows a first joint end 3 'with a male portion 5 and a second joint end 3 "with a female portion 7 of the respective threaded screw section 1', 1" in Fig. 1a extending along a central axis CA. The outer threads of the threaded screw sections 1 ', 1 " side is arranged with a set of trapezoidal threads 13. The male portion 5 comprises a threaded mounting pin 15. The female portion 7 comprises a threaded mounting hole 17, the pitch of which corresponds to that of the mounting pin 15. A first 19 'and second 19 "transverse holes are provided in the mounting pin 15. The female portion 7 comprises on both sides the mounting hole 17 a first hole set 21 'comprising two bushings 22' in line with each other and on both sides of the mounting hole 17 (seen in the transverse direction relative to the central axis CA). The female portion 7 comprises on both sides of the mounting hole 17 a second set of holes 21 "comprising two bushings 22" in line with each other and on both sides the mounting hole 17 (seen in the transverse direction relative to the central axis CA). The first transverse hole 19 'is received in the mounting pin 15 in such a way that it ends up in line with the first hole set 21' of the female portion 7 with such orientation that the entrance of each trapezoidal thread 13 at the first splice end 3 'ends up in the correct position in front of the corresponding trapezoidal thread 13. the orientation of the first transverse hole 19 'and the first hole set 21' (in line with each other) also determines a predetermined preload with the screw joint mounted. The threaded mounting pin 15 and corresponding thread mounting holes 17 have such threaded inputs that hole 19 'and the first set of holes 21' are aligned with each other. Correspondingly, the second transverse hole 19 "and the second set of holes 21" are defined. That is, the second transverse hole 19 "and the second set of holes 21" extend parallel to each other. the first transverse hole 19 'and the first set of holes 21'. 2b shows in a side view the splice ends 3 ', 3 "in Fig. 2a rotated in the position for securing. The first 19 'and the second 19 "transverse hole and the first 21' and the second 21" hole set are in the correct position relative to each other. Fig. 2c shows the splice ends 3 ', 3 "in a side view, in which view the section A - A is taken. Fig. 2d shows the section A - Ai Fig. 2c. A first pipe pin 25' is driven into the first transverse hole 19 ' and the first set of holes 21 'whereby the single screw joint locking tumor (not shown) is formed in the boundary area between mounting pin 15 and mounting hole 17. A second pipe pin (not shown) is similarly driven through the second transverse hole and the second set of holes.
    Fig. 3 shows a joint end 3 with several threaded inputs 26. Such a joint end 3 with multiple threaded inputs 26 requires extreme accuracy in mutually rotating adjustment of a first and a second threaded screw section so that corresponding threaded inputs 26 end up in position in front of each other.
    Figs. 4a-4d show an example of a method of finding a common centerline CL (see for example Fig. 4d) of transverse and through holes 19, 21 (hole set) of male and female portions. Fig. 4 shows how the first 1 'and the second 1 "threaded screw section (see for example Fig. 1a) have been twisted together by a fitter (not shown) in a first step by hand. The threaded screw sections 1', 1" have been twisted together by their respective mounting pin 15 (including outer thread) and mounting holes 17 (including inner thread) so much that the first transverse hole 19 (of the mounting pin 15) and the first hole set 21 (of the mounting hole 17) end up obliquely (initial skew) and not in line with each other. A second transverse hole and a second set of holes have the same orientation as the first transverse hole 19 and the first set of holes 21 relative to the central axis CA, but are obscured in the figure. A rotary measuring device 41 according to an embodiment (for example shown in Fig. 5a) is mounted around the first and the second threaded screw section 1 ', 1 ". Preferably, said initial inclination is provided in such a way that when a measuring pin 27, comprising a first portion 31 with truncated conical tip and a second portion 29 having a constant diameter, is inserted into the first transverse hole 19 and partially into the first transverse hole set 21 (after mounting the twister), the end of the truncated conical tip will end up in the area of the central axis CA. The first portion 31 has a smaller diameter than the second portion 29 of the measuring pin 27. Fig. 4b shows how the first 1 'and the second 1 "threaded screw section are rotated so that the measuring pin 27 completely collapses so that the second portion 29 of the measuring pin 27 fits into the first transverse hole 19. and the first set of holes 21. The position in Fig. 4b is referred to herein as an origin position UL or start position. Now the first 1 'and the second 1 "threaded screw section are further twisted together until the measuring pin 27 is fixed (stop position SL) and is in contact over contact points KP 11 of the first transverse hole 19 and the first hole set 21 as shown in Fig. 4c. The fitter thus turns the first 1 'and the second 1 "threaded screw section from the original position UL to said stop position SL clockwise in a first direction of rotation VR1 and notes a first mutual angle of rotation. The fitter can, if he wishes, remove the measuring stick 27 from the first transverse hole 19 and the first set of holes 21 in a subsequent step. Now the rotary measuring device is operated so that the first 1 'and the second 1 "threaded screw section are rotated in a first rotational angle VR1 opposite the second rotational direction VR2 with a second mutual rotational angle ß, which has half the value of the first mutual rotational angle groove. and the second 1 "threaded screw section in the second direction of rotation VR2 with half the angular value of the first mutual angle of rotation ot to an end position SP, wherein the first transverse hole 19 and the first set of holes 21 are aligned with each other. Thus, a definition of a hole pattern has been provided where the transverse hole 19 and the hole set 21 form the common center line CL. In a next step, the fitter drives tubing pins (not shown) through the first transverse hole 19 and the first set of holes 21 as well as through the second transverse hole and the second set of holes. When the two pipe pins are driven in, deformations of an edge region of the respective first and second transverse holes 19, 21 are automatically formed, which deformations permanently fix the screw joint in its correct position.
