    专利说明:

    The invention relates to a hydraulically constructed device, with the possibility of adding quick change, for mounting between an excavator's excavator arm and a utility tool, for example an excavator such as a bucket (see Figure 1 for illustration of how the device is included on an excavator's excavator arm). The device is of the kind that is built around a housing which converts forces to rotate a utility tool mounted thereon. The device is attached to the excavator arm excavator and is connected by the hydraulic system of the construction machine. The operator can hereby control the device from the panel in the contractor's cab to move the utility tool, turn it, or set it to a desired position. In this way, the operator achieves much more flexibility and adaptability in the mounted excavator for the specific excavation purpose than the new construction machine is equipped with and which otherwise requires a manually performed setting or manual change of excavator. When the operator from the cab activates the device, the hydraulic oil from the construction machine's hydraulic system is pressed down into the front chamber or rear chamber of the device, depending on the direction or movement of the device, and thus the tool to achieve, for example to carry out excavation work. For this purpose the device may be equipped with a quick change. The quick change is connected to the excavator's hydraulic system. The quick change contributes to the fact that digging tools can be changed from the cab control panel and thus switching between different mounted digging tools without the operator having to leave the cab. Without a quick change, this operation must be done manually. This hydraulic device operates with and without quick change.
    The known devices of this kind are characterized by the transfer of forces in a housing which is transferred to the device where the forces create the movement of the mounted utility tool which allows the utility tool to be tilted, turned, moved by the operator from the cab control panel when is connected to the hydraulic system of the construction machine.
    It is known from patent US 5,242,258 that the housing is constructed with twisted spools as well as built with twisted spools on the inside and outside of the piston, and also on the main shaft outside there are twisted spools. The twisted spools serve the purpose that as the piston travels back and forth it transmits the cancer from the housing via the twisted spools on the outside of the piston to the twisted spools on the inside of the piston, on which it causes the main shaft to rotate. In this type of device, it is the broken splices that convert the forces from motion to rotation. The broken splices are limited in size, as it is difficult to create large splices in the manufacturing process. At the same time, the broken splices are more prone to wear. Furthermore, the spleins are a fixed part of the structure. This means that even with relatively little wear, the ability to absorb the forces transferred from the excavator is considerably weakened, which, as the wear and tear is reduced, the bearing numbers of the splinters are reduced. Furthermore, the splinters are not a replaceable wear which means that this type of device is expensive to maintain and has a short life.
    From patent US20100095720 A1 it is known that the main shaft is constructed as a two-sided displacement cylinder. On the center of the main shaft is mounted a cylindrical slider which fixes the bottom of the device to the main shaft. On the other side of the main shaft, a slider with helical grooves is mounted. The angled grooves contact the fixed part of the device, on which there are also helical grooves. This means that as the main shaft is guided back and forth by the hydraulic oil, the force is transferred from the cylindrical sliding rail via the main shaft to the sliding rail with the angled grooves affecting the fixed part of the device and the device tilting. This type of device construction is vulnerable to extreme loads, so it is part of its construction that a dual hydraulic brake is fitted to the device which will lock the device when not in use.
    The problem with this type of device is that all forces are transmitted via a main shaft which is cross-drilled, and thus not very robust to the large stresses that it is exposed to from the construction machine. This problem is attempted to be solved temporarily, using hydraulic brakes at the ends of the device, here both ends. However, this design makes the product unnecessarily complex, increasing the number of wear parts while subjecting the structure to unnecessary force. These are elements of the design that shorten the life of the product.
    From Patent US2011 / 0154920A1 it is known that the housing is constructed where one half is cylindrical and the other half is elliptical. The cylindrical part of the housing is used as a bearing housing for the rotation and the elliptical part of the housing is used as cylinder walls for the main piston. The piston is designed as an ellipse. The elliptical portion of the housing constitutes the cylinder portion of the device. As the cylinder head is elliptical, it is capable of transmitting the forces from the fixed part of the device via the twisted spools on the main shaft of the device. In this type of device, all forces are transmitted via an elliptical housing to an elliptical piston. As a result of this construction, there are enormous forces on the walls of the house. This load causes the cylinder housing and cylinder walls to be subject to a somewhat higher degree of wear and tear than other devices. The unnecessary force effects increase the number of wear parts and give the device a short service life.
    It is a clear disadvantage that the known designs are characterized by either having many wear parts which are a fixed part of the structure of the device and thus not possible to replace, which shortens the quality and service life of the device and makes the device delicate to wear and quickly reduces the device's carrying number and / or having a complicated construction that does not utilize the forces optimally, and / or which creates an unnecessary impact on the wear parts, or creates a relatively clumsy product with low flexibility that makes maintenance and application problems difficult to read, the ability to use the forces optimally , number of wear parts and mounting height.
    The invention provides a device of the kind mentioned in the preamble, whereby with the invention of the construction, the carrying capacity is not lowered by use and / or wear, as is the case with existing similar devices. The invention also achieves a lower installation height, that wear parts are interchangeable, a significantly simpler construction, of which a considerably lower total weight is obtained which, among other things, makes it easier to handle in the use situation. In addition, the structure strengthens the device by having the forces being transposed solely for the purpose and not unnecessarily reacting forces or loading parts where forces do not benefit, including in the construction ensuring that the forces do not unnecessarily create wear parts, which directly affect the life of the device.
    This contributes directly to a device that, in addition to the aforementioned qualities, is far more flexible and user-friendly compared to existing devices. This is achieved according to the invention by means of a device of the kind mentioned above and characterized in that the device is made up of a housing consisting of external grooves and loose passports.
    The invention is mounted on the excavator arm of the construction machine and connected to its hydraulic system. The fixed part of the device is mounted on the excavator arm and the main shaft is attached to the fixed part. On the main shaft are mounted loose passes which guide the slide, where the loose passes lock the slide so that it does not rotate when this is not desired. On the outside of the slider there are twisted grooves, where in these grooves interchangeable loose passes or similar guides, such as cylindrical rollers, slide. The loose passports are fixed in the device housing with passport bolts. On the device, the hydraulic hoses are mounted at one end of the main shaft, where there are drilled channels leading to the front and rear of the device respectively. When the hydraulic oil is fed to the front or rear of the slider, respectively, the slider is pushed back and forth in motion. As the slider is fixed to the main shaft and the loose fit is fixed to the housing, the device gradually rotates to respectively. left or right, as determined by the operator from the construction machine control panel.
    With exterior twisted grooves and loose passports, a higher and more powerful passport and groove connection are obtained which provide a stronger construction and durable product compared to existing devices of a similar nature characterized by having splinters. In addition, with this construction of puffs and grooves, a unique greater height is achieved, which means that these are not subjected to the same degree of reduction in the ability to absorb the forces with wear and tear compared to existing solutions with, for example, tapered splines.
    The invention relates to a hydraulic device for mounting between an excavator's excavator arm and a utility tool, the main shaft being surrounded by a housing. The housing and the main shaft have center lines that are congruent, where on the main shaft, there is from each side of the housing a hollow flange, an end bracket, a fixing device consisting of, for example, a cradle, flange and a hollow flange, wherein hollow flange and end bracket are parts of the movable device. part, while the fixing cradle and flange are parts of the fixed part of the device, wherein the device further comprises a slider between the outer diameter of the main shaft and the inner diameter of the housing, wherein the slider is axially movable as a result of at least a pasfer / groove connection between the main shaft and the slider, and the passport / notch connection is parallel to or in line with the center lines of the main shaft and housing, and where further on the outside of the slider is a plurality of twisted notes having a configuration corresponding to a plurality of loose passports where the loose passports are utilized by a number of pass bolts, locking pins, bolts or for example by welding are connected to the housing and where in the main shaft or in the house are hydraulic ducts and hydraulic inlets / outlets. For this, where the at least one groove is located on the main shaft, while at least one groove is located on the inside of the slide.
    The grooves on the outside of the slider have a design in both extension and cross-section that corresponds to one or more loose fits. The loose puffs may have the shape roll-shaped, cylindrical, spherical or have a number of rounded or curved edges / surfaces. And where the loose passport (s) has an upper side, an underside and at least four edges / surfaces where the upper side and the underside are curved and where at least two of the sides are perpendicular to the curved upper side and the curved underside and have a number of holes in the the upper side along the center line of the loose passport (s). Furthermore, the loose passports can be interchangeable.
    In addition, the hydraulic device may optionally comprise a speed switch. The invention will be explained in more detail below with reference to the drawings, in which
