    A depth measurement system produces independent signals, each presumably corresponding to the same movement of a wireline if produced under ideal wireline measurement conditions. The system utilizes the signals to provide an accurate and repeatable signal under varying wireline measurement conditions and is particularly suitable for driving a recorder for depth recording and merging measurements from tools lowered in the borehole on different runs and to detect slippage between the wireline and a tangential wheel used to provide one of the signals. Slidably mounted measurement wheels insure tangential engagement of opposite sides of the wireline with equal pressure. Low-load signal generators each responsive to the rotation of the opposing wheels provide independent signals, each ideally corresponding to the movement of the wirline engaged between them. Magnetic marks written on the wireline are sensed and provide yet another independent signal. Automatic processing of these signals provides alarms and corrections for slippage, variations in measurement tension, and cable stretch.

    . (54) DEVICE FOR DETECTION OF LONGITUDINAL CABLE DISPLACEMENTS
    12 This invention relates to the measurement of the immersion depth in boreholes of various devices, when connected to the end of the Ka6eJiH, can also be used to detect the movement of the cable on the surface. A device for detecting longitudinal cable movements is known, comprising a chassis, two guide systems mounted on the chassis supporting two points at the cable, two platforms mounted on the chassis, installed on both sides of the cable; springs placed between platforms, two wheels fixed on platforms and in tangential contact with opposite sides, cable due to spring action Ci The disadvantage of this device is lack of reliability, since both wheels are mounted on two hinge brackets hinged on the chassis, and the spring located between the brackets presses one wheel to the other. If the cable is shifted to the side and becomes slightly skewed, the two-wheel axle can also shift to the side, following the lateral displacement of the cable. The purpose of this invention is to ensure the reliability of the device by stabilizing the force of pressing the wheel to the cable regardless of its transverse movements during movement. . . This goal is achieved by the fact that the platforms are mounted on the chassis with the possibility of moving relative to it in the direction perpendicular to the axis passing through the chassis guide systems. FIG. 1-3 presents a schematic diagram of the operation of the device. The device 1 includes a chassis. 2, consists of two parallel longitudinal rods 3 and 4, the rear ends of which 5 are fixed in block 6. The longitudinal axis of the chassis, indicated in the drawing by dashed straight 7, parallel to the rod m 3 and 4, is located at half the distance between them. Block 6 is secured with a full cardan at the lower end of console 8, the middle part of which is fixed to a controllable bracket. The classic full cardan has a cross-piece, the first of which CapL 9 is inserted into the Drill in the block b perpendicular to the core 3 and 4 of the hole in which it can rotate, and the second trunnion inserted into the drill drilled into the console 8 vertically and perpendicular to the direction of the controlled bracket hole in which it can rotate. A full cardan allows the longitudinal axis of the chassis to rotate in any direction, rotating around its center, etc. In this, the rods remain stationary. In normal operation, the bracket is located approximately horizontally, and therefore, the second spider hub is oriented vertically. The first pin 9 also lies approximately horizontally. The plane of symmetry 10 rods 3 and 4, located at half the distance between these two rods, is called, therefore, the axial plane of the chassis, also supported strictly vertical. At an equal distance from the axial plane of the chassis, on the bottom surface 11 of the block b, rotating cylindrical rollers 12 and 13 are installed, between which the cable passes. The rollers 12 and 13 are arranged vertically on the full cardan and allow the cable to be guided by means of a controllable bracket on. The lateral force applied by rollers 12 and 13 does not counteract the orientation of the chassis along the cable. The orientation of the chassis along the cable is supported by two guide systoles 14 and 15, installed respectively on the back and front ends of the rods 3 and 4. The guide system 14 has a housing 16 formed by two tubular parts 17 and 18, drawn on rods 3 and 4 respectively, two longitudinal side walls 19 and 20 and two transverse ribs 21 perpendicular to the tubular parts 17 and 18, housing 16 also has two drums 22 and 23 located opposite each other and intersecting respectively side walls 19 and 20. In drums 22 and 23 trptidBepineHH Co-axial holes in which two ball bearings 24 and 25 are inserted. Wheel 26 is stuck on a hub, rotating in ball bearings 24 and 25. Wheel swivel axis: 6 is also perpendicular to the axial plane of the chassis. Pulley 27, peripheral groove 28 in the shape of the letter U , thanks to the ball bearing 29, can rotate with on the bracket 30, hingedly fastened to the axle 31, a part of the transverse ribs 21 located in the lower part 21. The bracket 30 has an extension 33 on the other side of the axle 31, the tip of which is connecting rod 32 pivotally attached. Connecting rod 32 there is a flange 35 that can slide in the cylinder 36 in the direction bounded by a ring 37. The spring 38 is clamped between the flange 35 and the bottom of the cylinder 36 to which the extension 39 is attached, pivotally connected by means of a pin 40 with a hand 41. Hand 41 in it is pivotally attached to a pin 42 fixedly mounted on the transverse edge 21. When the handle 41 is in the lower position, the spring 38 is compressed and pushes the extension 33 of the bracket 30 down. The pulley 27 in this case is pushed up and presses the cable to the wheel 26. To release the cable handle 41 is shifted to the upper position, the spring 38 is depressed and allows the pulley 27 to tilt down around the trunnion 31. The guide system 15, located next to the block 6, is similar to the system 14 and has a wheel 43 and the pulley 44, identical to the wheel 26 and the pulley 27 However, the wheel hub 43 is connected by means of a bevel gear to a square rod, carried along by the rotation of the wheel 43. This rod is connected to a mechanical drive, which can be replaced in case of emergency by an electric drive. Between the two guide systems 14 and 15 on two rods x 3 and 4 a paired cable displacement detection system is reinforced. In the four corners of the rectangular frame 45, there are upward and gripping rod 3 and 4 clamps 46, the vertical slit 47 allows clamping the rod in the clamp with a screw 48. The rear transverse part of the frame has two clamps 49 directed down relative to the axial plane of the chassis and intended to grip the transverse tube 50. Screws 51 clamp the tube 50 in Clips 49 and support it perpendicular to the axial plane. In the middle of the transverse part of the frame 45c. nuts 52 p in an adjustable position, a clamp 53 is fixed in which the second transverse tube 54. On two sides of the axial plane, platforms 55 and 56 are installed, sliding along transverse tubes 50 and 54. Platform 55 has two hollow tubular parts 57 and 58 connected by two spacers 55 and 60 with the central annular part 61. The tubular parts are elongated downwards by means of stacks 62 and 63, the lower parts of which are connected to an openwork gasket 64. The sleeves with balls 65 and 66 supported by spring rings 67 and 68. Sleeves with balls 65 and 66 can slide in the tube 50. On the cover 69, enclosed in the tubular part and having a gasket 70 and 71, there is a section with a thread 72, and a hole 73 for the roller 74 is drilled at the end of the said cover. The cap is screwed onto the part with a thread 72. At the opposite end The tubular part is fixed with an elastic accordion 75, which prevents the penetration of large particles of dust into the sleeves with balls. A spring 76 is inserted inside the tube 50. The tubular part is made sliding against the transverse tube, also containing springs, which press the platform to each other. The ultrastatic mounting of the two platforms on the transverse tubes with ball-sleeves makes the system of two tubes non-deformable, which does not require rigid fastening of the frame to the chassis. For this, it is sufficient that the tubes are fixed to the chassis at three points, and the position of one of them can be adjusted.
    On the central part, with screws (not shown), the bearing housing 77 is fixed, in which the ball bearing 78 is mounted. In the center of the openwork plate, another bearing bearing housing with a ball bearing is attached with screws. Inside these two bearings there is a rotating bushing 79 of the measuring wheel 80, which is in tangential contact with the cable in case the platform tends to turn to the axial plane under the action of the spring.
    In the upper part of the casing of the bearing, the case of the photoelectric encoder 81 is fixed. This classical type encoder has a disk on which transparent and opaque zones are engraved alternately closer to the edges, blocking the optical path between the light source and receiving cells. The encoder disk 81 is connected to the sleeve 79, the measuring wheel 80 The encoder outputs two signals of frequencies proportional to the speed of rotation of the wheel, and these two signals change the phase Hail90, depending on the direction of rotation. The second measuring wheel 82 also rotates on the platform, Tangential contact with the other side of the cable. On the platform, a second coding transmitter is installed, identical to the encoder, generating signals characterizing the angular displacements of the second measuring wheel. It can be seen that the cable is clamped between two measuring wheels by means of a spring, however these springs do not have any resistance transverse to the displacements of the system formed by two measuring wheels, which are caused by the bending of the cable into the horizon.
    talnoe plane. At the optimum position of the measuring device, the points of support of the measuring wheels lie on the horizontal straight line, and the forces pressing the wheels to the cable have the opposite direction and are equal to each other, since they arise under the action of two springs.
    In order to be able to insert the cable between the measuring wheels, there are means for breeding the latter on the chassis. A vertical shaft 84 is installed in the middle of the clamp 83 fixed on the longitudinal rods and can be rotated at the lower end. The upper part of the shaft 84 has an inclined knob 86, which allows manually turning the cam 85, on which there are two closely spaced protrusions 87 and 88 and two more distant grooves connected to the protrusions with round symmetrical lines. The shoulder 89 is fixed on the side of the platform with screws 90 and extends horizontally to the cam projections. Another symmetrical shoulder is fixed on the platform. When turning the knob 86 clockwise, the cam pushes the shoulder outward and spreads the measuring wheels, allowing the cable to run between them. Turning the handle in the opposite direction releases the platform and two measuring wheels by the action of springs that can enter. contact with the cable.
