Description

Technical Field

[0001] The utility model belongs to the technical field of railway wheel manipulators, and in particular relates to a railway wheel manipulator clamp gear box repairing device. Background Art

[0002] As the country's modernization strength continues to increase, the rail transit industry, especially the railway transportation industry, continues to develop, and the variety of train wheels is increasing to meet different transportation needs and occasions.

[0003] In the train wheel processing industry, most domestic and foreign manufacturers use truss manipulators, which are composed of an integral truss, a lifting column, and a rotatable clamping clamp. This type of manipulator is flexible and stable to use during the transportation of wheel materials. However, after years of field experience, it has been verified that the gearboxes on both sides of the manipulator clamp adopt an integrated design. After a certain period of production, if the weight of the manipulator clamping the wheel is too large, it will produce a large torque on the gearboxes on both sides, causing the clamp gearbox retaining spring groove to crack. When the retaining spring groove partially cracks, the crack gradually extends, causing the entire gearbox to tear, and then causing the manipulator to clamp the wheel to fall off, which poses a serious safety hazard. At the same time, once the retaining spring groove cracks, the entire lateral gearbox body cannot be used, and the spare parts cost loss is serious. In response to the above problems, there is currently no suitable repair method to avoid this design defect.

[0004] The invention patent with announcement number CN108422438A was disclosed on August 12, 2018. The wheel detection clamp includes a base plate and a pair of clamps for clamping the wheel that are relatively movable and arranged at the lower part of the base plate. A clamp is arranged on the inner side of the clamp, and the clamp is arranged on the clamp through a rotating shaft. The clamp is provided with a driving structure for driving the clamp to rotate. The gearboxes on both sides of the wheel detection clamp are of integrated design. When the load is too heavy, the force on the clamp rotating shaft increases, and the retaining ring groove between the two bearings of the aluminum box rotating shaft is prone to cracking. As the crack extends, the gearbox will tear, causing the robot to clamp the wheel unsteadily and cause a wheel drop accident, and the stability of the robot clamping the wheel cannot be guaranteed.

[0021] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0022] like Figures 1 to 3 As shown, the train wheel manipulator clamp gearbox repair device has a mounting groove 7 at the bottom of the gearbox 1, a retaining spring steel sleeve 2 is detachably connected to the mounting groove 7, a mounting step 9 is provided in the mounting groove 7, a flange 8 is provided at the end of the retaining spring steel sleeve 2, the mounting step 9 cooperates with the flange 8, and the mounting step 9 and the flange 8 are connected by bolts 4.

[0023] The device has a split design for the easily damaged circlip groove of the gearbox 1, expands the gearbox 1, and designs a separate circlip steel sleeve 2 so that it can be connected in a detachable manner. The circlip steel sleeve 2 is made of steel and is built into the circlip groove to improve the structural strength of the gearbox 1, making it less prone to damage and cracking, and thus helping to improve the stability of the robot operation. The circlip steel sleeve 2 is connected by bolts 4 to facilitate later maintenance. The circlip steel sleeve 2 is installed on the aluminum gearbox 1 by a combination of bolts 4 and wire screw sleeves 3, which minimizes the deformation of the aluminum reduction housing caused by the locking of the steel sleeve bolts 4 and avoids damage to the housing.

[0024] like Figure 1 and Figure 2 As shown, a connection hole 6 is provided on the flange 8, and a blind hole 5 is provided on the mounting step 9. The connection hole 6 is a stepped hole, and one end of the bolt 4 is located in the connection hole 6, and the other end is connected to the blind hole 5. The extrusion surface of the bolt 4 presses the step surface of the stepped hole. The stepped hole can prevent the disassembly end of the bolt 4 from being exposed, reduce the risk of collision, and ensure long-term reliable connection.

[0025] like Figure 2As shown, a wire screw sleeve 3 is sleeved on the bolt 4. The wire screw sleeve 3 is made of aluminum, which is consistent with the material of the gear box 1, and the connection is more stable. The wire screw sleeve 3 has a certain elasticity, which can disperse the stress to protect the base thread, so that the load distribution on each circle of the thread is more uniform, thereby improving the strength of the threaded connection, so that the screw will not loosen when subjected to impact vibration, and has the function of shock resistance and loosening prevention. When the wire screw sleeve 3 is used for a long time, the thread on the bolt 4 may be disengaged or the thread is disordered. The wire screw sleeve 3 can prevent the connection from completely failing, and extend the service life of the bolt 4. In addition, the wire screw sleeve 3 has a higher hardness, less wear during assembly and disassembly, can be used repeatedly, and is easy to maintain.

[0026] like Figure 1 and Figure 2 As shown, the installation groove 7 is adapted to the circlip steel sleeve 2, and the side of the circlip steel sleeve 2 is in the same plane as the side of the gear box 1. The above structure allows the installed circlip steel sleeve 2 to be completely inside the gear box 1, reducing the risk of the circlip steel sleeve 2 being exposed and ensuring long-term reliable connection.

[0027] like Figure 1 As shown, a bearing 10 is arranged inside the circlip steel sleeve 2, and the bearing 10 cooperates with the circlip steel sleeve 2, and an oil groove 11 is arranged inside the circlip steel sleeve 2. The oil groove 11 is used to contain lubricating oil to reduce the friction of the bearing 10 when rotating.

[0028] like Figure 3 As shown, the blind holes 5 are arranged at equal intervals along the circumferential direction. There are six blind holes 5 to ensure a stable connection, provide a uniform connection effect for the connection of the circlip steel sleeve 2, and make the circlip steel sleeve 2 accurately and tightly fit with the installation groove 7.

[0029] The material of the circlip steel sleeve 2 is 45# steel. The circlip steel sleeve 2 is made of 45# steel and is heat-treated, with high structural strength and strong anti-deformation ability.

[0030] like Figure 2 As shown, the bolt 4 is a hexagon socket bolt. The hexagon socket bolt has the advantages of compact size, relatively longer threaded part, small space occupation, and the use of the hexagon socket screw as a connecting piece will not affect other components, nor will it reduce the structural strength of the spring steel sleeve 2, and the hexagon socket bolt can be installed in a deeper position, and the connection is more secure.

[0031] The working principle is as follows: when clamping a heavy wheel, since the circlip steel sleeve 2 is made of heat-treated 45# steel, which is harder than the aluminum gearbox 1 on both sides of the manipulator clamp, it is not easy to be damaged by large torque, and the circlip groove is not easy to crack. At the same time, since the circlip steel sleeve 2 and the aluminum gearbox 1 on both sides of the manipulator clamp are connected by a combination of hexagon socket bolts and aluminum steel wire screw sleeves 3, the damage to the aluminum gearbox 1 caused by excessive tightening torque of ordinary hexagon socket bolts is avoided, and it is not easy to cause thread deformation and damage. When the components in the manipulator circlip steel sleeve 2 are damaged, there is no need to replace the entire manipulator gearbox 1, only the circlip steel sleeve 2 needs to be replaced, which extends the service life of the spare parts and saves costs to a great extent.

[0032] The train wheel manipulator clamp gear box repair device has a split design for the gear box 1. The circlip steel sleeve 2 is connected with bolts 4 and combined with the use of a wire screw sleeve 3. The circlip steel sleeve 2 is built into the circlip groove, which not only facilitates the subsequent maintenance process and saves costs, but also improves the structural strength of the gear box 1, extends the service life of spare parts, makes the gear box 1 less prone to damage and cracking, ensures stable and reliable movement of the manipulator, avoids the occurrence of wheel falling, and eliminates safety hazards in the operation process.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
