Description

Technical Field

[0001] This application relates to the field of construction machinery and equipment, and in particular to an auxiliary tool for disassembling and assembling bulldozer support rollers. Background Technology

[0002] Track rollers are important components mounted on both sides of the chassis of construction machinery (such as bulldozers, excavators, and tanks) to increase vehicle stability, improve traction, and reduce ground pressure on the vehicle. Track rollers typically consist of components such as hubs, rims, tires, and bearings. The weight of the track rollers increases the vehicle's traction, making it easier to push or dig in complex road conditions.

[0003] Regarding the aforementioned technologies, the inventors believe that in areas with harsh construction conditions and terrain, bulldozer track rollers have a short service life and require frequent replacement, making it difficult to transport the equipment back to the base for repair. At earthquake project sites, existing repair techniques and tools are insufficient to meet repair requirements, necessitating a large workforce and lengthy repair cycles, thus impacting the project's road-pushing progress.

[0024] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] This application discloses an auxiliary tool for disassembling and assembling bulldozer track rollers. (Refer to...) Figure 1 , Figure 2 A bulldozer track roller disassembly and assembly auxiliary tool includes a support assembly 1 for supporting the track roller, a movable assembly 2 at the bottom end of the support assembly 1 located at the end of the support assembly 1 opposite to the track roller, and a gripping assembly 3 at the top end of the support assembly 1 located on the side of the support assembly 1 opposite to the track roller. By moving the gripping assembly 3, the support assembly 1 is tilted around the movable assembly 2 as a fulcrum, which in turn tilts the track roller on the support assembly 1, thereby moving the support assembly 1 and the track roller on the support assembly 1.

[0028] The support assembly 1 includes a support frame 11, which is a rectangular frame structure. The support roller is located inside the support frame 11. The length of the support frame 11 is not less than the length along the axis of the support roller, so that the support roller can be completely located inside the support frame 11 along its axis. The width of the support frame 11 is not greater than the diameter of the support roller, so that the support roller can be engaged with the top of the support frame 11.

[0029] An abutment rod 12 is provided on the side of the support frame 11 near the gripping assembly 3. The side wall of the abutment rod 12 passes through the side wall of the support frame 11, and the abutment rod 12 is threadedly connected to the support frame 11. The direction of the abutment rod 12 is parallel to the axis of the support roller. By rotating the abutment rod 12, the abutment rod 12 moves along its axis. The end of the abutment rod 12 near the support roller abuts against the support roller, and the end of the support roller away from the abutment rod 12 abuts against the support frame 11. The abutment rod 12 and the support frame 11 lock and limit the support roller.

[0030] An abutment plate 121 is fixedly connected to one end of the abutment rod 12 near the support roller. The abutment plate 121 has a circular structure and its diameter is larger than that of the abutment rod 12, so that the abutment plate 121 can increase the contact area with the support roller and provide better support for the support roller.

[0031] The holding assembly 3 includes a handle 31, which is fixedly connected to the side wall of the support frame 11. The handle 31 is inclined, gradually tilting upwards from the end near the support frame 11 to the end away from the support frame 11. A pull handle 32 is fixedly connected to the end of the handle 31 away from the support frame 11, and the pull handle 32 is parallel to the support frame 11. The length of the handle 31 is greater than the length of the support frame 11, so that the handle 31 and the support frame 11 form a lever structure with the moving assembly 2 as the axis. The end of the handle 31 is the power arm, and the support frame 11 is the resistance arm, which is used to lift, lower, and move the support roller for maintenance work.

[0032] Reference Figure 3 , Figure 4 The movable component 2 includes a movable housing 21, which is located at the bottom of the support frame 11 and is fixedly connected to the support frame 11. The movable housing 21 is a hollow cylindrical structure, and the axis of the movable housing 21 is set horizontally.

[0033] A movable shaft 22 is installed inside the movable housing 21, coaxially with the movable housing 21, with both ends of the movable shaft 22 extending from the ends of the movable housing 21. Wheels 23 are respectively provided at both ends of the movable shaft 22 on the outside of the movable housing 21. A first fine-tuning part 24 is provided on the movable shaft 22 opposite to the movable housing 21, and a second fine-tuning part 25 is provided on the movable shaft 22 opposite to the wheels 23. The first fine-tuning part 24 can adjust the amount of rotation between the movable shaft 22 and the movable housing 21, and the second fine-tuning part 25 can adjust the amount of rotation between the movable shaft 22 and the wheels 23.

[0034] The diameter of the movable shaft 22 inside the movable housing 21 is larger than the diameter of the movable housing 21. A diameter reduction step 223 is provided between the large diameter portion 221 and the small diameter portion 222 of the movable shaft 22. One end of the diameter reduction step 223 has the same diameter as the portion of the movable shaft 22 inside the movable housing 21, and the other end of the diameter reduction step 223 has the same diameter as the portion of the movable shaft 22 outside the movable housing 21. The diameter of the diameter reduction step 223 gradually decreases from the side closer to the inside of the movable housing 21 to the side away from the inside of the movable housing 21.

[0035] The first fine-tuning part 24 includes a first bearing 241, which is coaxially arranged with the moving shaft 22 and sleeved on the outside of the moving shaft 22. The inner ring of the first bearing 241 abuts against the moving shaft 22, and the outer ring of the first bearing 241 abuts against the inner sidewall of the moving housing 21. The first bearing 241 is located at the small diameter portion 222 of the moving shaft 22, and the inner ring of the first bearing 241 abuts against the reduced diameter step 223. The first bearing 241 enables rotation between the moving housing 21 and the moving shaft 22.

[0036] The second fine-tuning part 25 includes a second bearing 251, which is coaxially arranged with the moving shaft 22 and sleeved on the outside of the moving shaft 22. Two second bearings 251 are located inside the wheel body 23 and are arranged opposite each other. The inner ring of the second bearing 251 abuts against the moving shaft 22, and the outer ring of the second bearing 251 abuts against the inside of the wheel body 23. The second bearing 251 enables rotation between the wheel body 23 and the moving shaft 22.

[0037] A limiting ring 26 is provided between the first bearing 241 and the second bearing 251. The limiting ring 26 has a ring structure and is sleeved on the outside of the moving shaft 22. One end of the limiting ring 26 abuts against the inner ring of the first bearing 241, and the other end abuts against the inside of the second bearing 251. The limiting ring 26 limits the movement between the first bearing 241 and the second bearing 251, and the positioning of the second bearing 251 leaves a gap between the side wall of the wheel body 23 and the end of the moving housing 21.

[0038] The two ends of the movable shaft 22 are threaded with locking nuts 27 on the side of the wheel body 23 away from the movable housing 21. The locking nuts 27 restrict the movement of the wheel body 23 and position the wheel body 23 on both sides.

[0039] The rotation adjustment between the movable housing 21 and the movable shaft 22 is achieved through the first bearing 241, and the rotation adjustment between the wheel body 23 and the movable shaft 22 is achieved through the second bearing 251. This allows the entire support frame 11 to be finely adjusted at the installation position, precisely inserting the support roller into the installation position.

[0040] When used in soft soil and ordinary soil classified in engineering geology, a track is provided below the wheel body 23, and the outer wall of the wheel body 23 abuts against the track. The track reduces the wheel body 23 from sinking into the soil.
