Description

Technical Field

[0001] This utility model relates to a tool for disassembling the drive wheel of a tracked vehicle, and particularly to the field of disassembly and assembly tools. Background Technology

[0002] Tracked vehicles have heavy drive wheels, making disassembly and assembly time-consuming and labor-intensive. Currently, when drive wheel malfunctions need repair in a repair shop, the disassembly and installation of the running gear are mostly done by hammering with sledgehammers and timber. In field conditions, repairs require mechanics to crawl under the vehicle, and without a trench, working under the vehicle is extremely dangerous and difficult. Disassembling running gear components is very challenging, especially those that are rusted, making disassembly extremely difficult, or even impossible. Utility Model Content

[0003] This utility model provides a tracked vehicle drive wheel disassembly tool that is simple in structure, low in manufacturing cost, and easy to carry and use.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A tool for disassembling the drive wheel of a tracked vehicle includes a pressing device installed in the drive wheel axle hole, a lead screw installed above the pressing device, a support rod disposed on the lead screw, and a pulling hook hinged to both ends of the support rod.

[0006] Furthermore, the support rod is provided with pin holes at both ends, and the end of the lifting hook connected to the support rod is provided with a through hole. The pin holes are provided in correspondence with the through holes, and a pin is provided in the pin holes.

[0007] Furthermore, a safety chain is provided between the pin and the hinge pin located on the same side of the support rod.

[0008] Furthermore, the lifting hook is provided with anti-slip teeth.

[0009] Furthermore, a nut is provided at one end of the lead screw, and a spherical support section is provided at the other end. A spherical groove is provided on the upper part of the pressing device, and the spherical support section is matched with the spherical groove.

[0010] Furthermore, a wrench is provided above the lead screw, a threaded sleeve is provided on the lower side of the wrench, a handle is provided on the upper side of the wrench, and a groove is provided inside the threaded sleeve, which is configured to cooperate with the nut.

[0011] The beneficial effects of adopting the above technical solution are as follows:

[0012] This utility model innovates the design of the tool for disassembling and assembling the drive wheel of a tracked vehicle, making it easy to carry and repair. It changes the previous crude method of disassembly and forced removal. Using this device, time and labor are saved, greatly improving the efficiency of field operations and enhancing safety during use. In other words, the repair work environment using this utility model does not require repairmen to crawl under the vehicle body, ensuring safety, solving the drawbacks of time-consuming and labor-intensive repair work, and improving repair efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-5 As shown, this utility model provides a tool for disassembling the drive wheel of a tracked vehicle. It includes a pressing device 1 installed in the drive wheel axle hole, a lead screw 2 installed above the pressing device 1, a support rod 4 mounted on the lead screw 2, and a lifting hook 3 hinged to both ends of the support rod 4. The support rod 4 has pin holes 41 at both ends. The lifting hook 3 has a through hole 32 at the end connected to the support rod 4. The pin holes 41 and through holes 32 are correspondingly arranged. A pin 6 is installed in the pin hole 41. A safety chain 7 is installed between the pin 6 and a hinge pin located on the same side of the support rod 4. The safety chain 7 prevents the pin 6 from being lost or falling off, facilitating carrying and use. The lifting hook 3 has anti-slip teeth 31, which prevent the lifting hook from falling off after hooking the drive wheel gear ring, improving the connection strength.

[0021] The lead screw 2 is provided with a nut 21 at one end and a spherical support section 22 at the other end. The upper part of the pressing device 1 is provided with a spherical groove 11. The spherical support section 22 is matched with the spherical groove 11. The spherical support section 22 can be installed into the spherical groove 11. The spherical body can be used at a wider range of angles and can be used as a universal pressing device.

[0022] A wrench 5 is provided above the lead screw 1, a threaded sleeve 51 is provided on the lower side of the wrench 5, and a handle 52 is provided on the upper side of the wrench 5. A groove is provided inside the threaded sleeve 51, and the groove is configured to cooperate with the nut 21. The nut 21 can be in the shape of a hexagonal nut. The cross-sectional shape of the groove matches the cross-sectional shape of the nut 21. In use, the groove of the threaded sleeve 51 is used to lock the nut 21, and the handle 52 is rotated to drive the threaded sleeve 51, the nut 21 and the lead screw 2 to rotate.

[0023] The specific operation and usage process is as follows:

[0024] First, remove the pin 6 on the support rod 4 so that the movable pull hook can swing automatically. Then, install the pressing device into the shaft hole of the drive wheel. Rotate the handle 52 so that it drives the threaded sleeve 51, nut 21 and lead screw 2 to rotate in sequence. Adjust the position of the lead screw 2 until the pull hook 3 hooks the drive wheel gear ring. Then, install the pin 6 into the pin hole 41 to lock the pull hook 3 and prevent it from rotating. Then continue to rotate the handle 52 so that the threaded sleeve 51 drives the nut 21 and lead screw to continue to rotate. Under the action of the pull hook 3, the drive wheel is pulled out and removed.

[0025] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
