DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0031] The embodiment of the present application discloses a convenient workpiece disassembly vehicle.

[0032] Reference Figure 1 and Figure 2A convenient workpiece disassembly vehicle includes a vehicle frame 1. An operator can use the vehicle frame 1 to push the convenient workpiece disassembly vehicle to the vicinity of a bearing to be disassembled, and the vehicle frame 1 has sufficient flexibility. A support plate 2 is provided on the vehicle frame 1, and a first hydraulic cylinder 4 is fixedly provided on the support plate 2. The cylinder body of the first hydraulic cylinder 4 is provided with a plurality of disassembly claws 5 at equal intervals along its own circumference. The disassembly claws 5 are all parallel to the extension direction of the piston rod of the first hydraulic cylinder 4. The end of the disassembly claw 5 away from the first hydraulic cylinder 4 is provided with a fixing portion 51 extending toward the direction close to the axis of the piston rod. The disassembly claws 5 are all rotatably connected to the cylinder body of the first hydraulic cylinder 4 around their own axis.

[0033] Reference Figure 1 and Figure 2 The part where the first hydraulic cylinder 4 is connected to the disassembly claw 5 is set as a connecting part 41. The connecting part 41 is provided with a plurality of strip holes 411 extending radially along the piston rod of the first hydraulic cylinder 4. The strip holes 411 correspond to the disassembly claw 5 one by one. The disassembly claw 5 is penetrated in the corresponding strip holes 411. The end of the disassembly claw 5 close to the connecting part 41 is provided with a thread. Both sides of the connecting part 41 along the axial direction of the disassembly claw 5 are abutted with nuts 6 threadedly connected to the disassembly claw 5. The connection mode of the thread and the nut 6 ensures the rotation and fixing ability of the disassembly claw 5. The length of the disassembly claw 5 on the side of the piston rod of the first hydraulic cylinder 4 can be adjusted by adjusting the positions of the two nuts 6, which is convenient for adapting to bearings of different thicknesses and further enhancing the applicability. The setting of the strip holes 411 can ensure the rotation, fixing and length adjustment ability of the disassembly claw 5. The disassembly claw 5 can move along the strip holes 411 to adjust the distance between the disassembly claw 5 and the piston rod of the first hydraulic cylinder 4, which is convenient for adapting to bearings of different diameters and further enhancing the applicability.

[0034] Reference Figure 1 and Figure 2 In addition, a fixed chain (not shown in the figure) can be added. The fixed chain can be a common chain. The fixed chain is used to fix the relative position of the disassembly claw 5 and the workpiece. The disassembly claw 5 is additionally assisted by the fixed chain to fix the bearing, thereby enhancing the fixation of the bearing and improving the stability of the disassembly process.

[0035] Reference Figure 1 and Figure 2 When disassembling a large bearing, the disassembly claw 5 and the fixing portion 51 are used to support the bearing in front of the first hydraulic cylinder 4, and the bolts are loosened and tightened to make the disassembly claw 5 adapt to the size of the corresponding bearing. Then, the piston rod of the first hydraulic cylinder 4 is extended to realize the disassembly of the bearing. The tool is simple and does not require a lot of manpower. In addition, since the components are all installed on the frame 1, it is also convenient to use the frame 1 to quickly adjust the position of the whole, so that large-volume bearings have higher disassembly and assembly convenience.

[0036] Reference Figure 1 and Figure 2In addition, in this embodiment, the support plate 2 is slidably connected to the frame 1 in the vertical direction. The frame 1 is provided with a lifting assembly 3 for driving the support plate 2 to rise and fall. The lifting assembly 3 controls the lifting and falling of the support plate 2 to adjust the height of the first hydraulic cylinder 4. The operator uses the lifting assembly 3 to adjust the height of the support plate 2 according to the size and position of the bearing, thereby ensuring that the first hydraulic cylinder 4 and the disassembly claw 5 are in a suitable working position, thereby facilitating the disassembly of bearings at different heights within a certain range, which is conducive to enhancing applicability.

[0037] Reference Figure 1 and Figure 2 Specifically, the lifting assembly 3 includes a second hydraulic cylinder 31, a reversing wheel 32 and a transmission chain 33. The piston rod of the second hydraulic cylinder 31 is vertically upward, and the reversing wheel 32 is rotatably connected to the frame 1 above the second hydraulic cylinder 31. One end of the transmission chain 33 is fixed to the piston rod of the second hydraulic cylinder 31, and the other end bypasses the reversing wheel 32 and is fixed to the support plate 2. The second hydraulic cylinder 31 can pull the support plate 2 up through the reversing wheel 32 and the transmission chain 33, and at the same time, it can also cooperate with the gravity of the support plate 2 to realize the lowering of the support plate 2. The structure is simple and reliable.

[0038] Reference Figure 1 and Figure 2 In this embodiment, the second hydraulic cylinder 31 is controlled by a hydraulic operating handle 7. The hydraulic operating handle 7 is used to adjust the second hydraulic cylinder 31, which is a conventional prior art in the art. It is the same principle as that of a hydraulic vehicle and will not be elaborated in detail in this embodiment. The operator can use the hydraulic operating handle 7 to adjust the second hydraulic cylinder 31 at any time, which has stronger functionality and is more convenient for the user to perform operations such as adjustment at any time.

[0039] Reference Figure 1 and Figure 2 Moreover, since the transmission chain 33 is subjected to a relatively large force, and the bearing vicinity is also subjected to a large force, it is easy to cause the transmission chain 33 to break accidentally or other parts to collapse and fly. Therefore, a fixed protective net cover 11 can be added to the side of the frame 1 close to the hydraulic operating handle 7 to prevent accidents such as accidental breakage of the transmission chain 33 or accidental collapse and flying of parts near the bearing, thereby ensuring the safety of the operator.

[0040] The working principle of a workpiece convenient disassembly vehicle in an embodiment of the present application is as follows: the bearing is supported in front of the first hydraulic cylinder 4 by using the disassembly claw 5 and the fixing part 51, and then the piston rod of the first hydraulic cylinder 4 is extended to realize the disassembly of the bearing, and the height of the support plate 2 can be adjusted by the lifting assembly 3. The positions of the two nuts 6 or the positions of the disassembly claws 5 in the strip holes 411 can also be adjusted to fix bearings of different sizes. Finally, the bearing is further fixed by using a fixing chain, and then the disassembly work can be started, so that large-volume bearings have higher disassembly and assembly convenience.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
