Description

Technical Field

[0001] The invention belongs to the technical field of tracked special vehicles, and in particular relates to a device for disassembling a road wheel of a tracked special vehicle. Background Art

[0002] Tracked special vehicles are generally equipped with 16 to 24 road wheels. During use, it is often necessary to replace the road wheels, balance elbows, torque shafts and other parts that are damaged during use. The specific situations include the following:

[0003] 1. When the road wheel disc is damaged, it is necessary to replace the damaged road wheel disc;

[0004] 2. When the road wheel hub and internal bearings and other parts are damaged, the road wheel disc needs to be removed and then replaced;

[0005] 3. When the balance elbow is damaged, you need to remove the road wheel first, and then remove the damaged balance elbow for replacement;

[0006] 4. When the torque shaft is damaged, you need to remove the road wheel first, and then remove the damaged torque shaft for replacement;

[0007] 5. When the balance elbow support parts such as the needle bearing are damaged, you need to first remove the road wheel plate, torque shaft and balance elbow, and then remove the damaged needle bearing and other support parts for replacement.

[0008] At present, the existing means of disassembling the road wheels of tracked special vehicles are backward, and there are mainly two means, including whole vehicle hoisting disassembly and disassembly with the help of road wheel disassembly tools. Among them, whole vehicle hoisting disassembly is generally used in overhaul workshops. First, the track is disconnected at the driving wheel, and then after the whole vehicle is hoisted, the front and rear parts of the vehicle body are supported on two brackets, so that the lower track falls on the ground, and the road wheel is out of contact with the track and is in a suspended state, and then replaced; when disassembling with the help of road wheel disassembly tools, there is a risk of hand crushing during use and a risk of unbalanced force during the support process.

[0009] Whether it is the whole vehicle hoisting method, other disassembly methods, or the use of road wheel disassembly tools, it takes a long time, the maintenance efficiency is low, and there are safety hazards in use. Therefore, it is urgent to develop a high-efficiency crawler special vehicle road wheel disassembly device. Summary of the invention

[0024] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0025] This embodiment provides a track-type special vehicle road wheel piece removal device, the overall structure of which is as follows: Figure 1 As shown, it includes a road wheel support seat body 1, a first lug 2 and a second lug 3. Among them, the front and rear ends of the road wheel support seat body 1 have inclined structures for the road wheel to roll in and out, and the top end has an arc structure for placing the road wheel. The first lug 2 is set at the bottom of the road wheel support seat body 1, and is stuck between the two track end couplers when the road wheel blade is disassembled. The second lug 3 is set on the side of the road wheel support seat body 1, and is stuck between the two guide teeth when the road wheel blade is disassembled.

[0026] The tracked special vehicle road wheel blade removal device is made of medium carbon alloy steel, which has good rigidity after heat treatment, and the heat treatment hardness is HRC40-45. At the same time, the tracked special vehicle road wheel blade removal device adopts micro-nano zinc infiltration treatment technology, and the surface zinc infiltration layer thickness is 0.06-0.09mm, ensuring that the device can be used for a long time without rusting.

[0027] The method for using the track-type special vehicle road wheel piece removal device of the present invention is as follows:

[0028] a. First, place the road wheel blade removal device in front of the road wheel to be removed. At this time, the road wheel blade removal device is located on the track, the first ear 2 is stuck between the two track end couplers, and the second ear 3 is stuck between the two guide teeth. Figure 2 shown.

[0029] b. Start the vehicle and move it forward slowly. At this time, the inner road wheel gradually approaches the road wheel blade removal device and gradually falls into the top arc of the road wheel support seat body 1. Stop the vehicle and brake and shut down. At this time, the road wheel blade removal device supports the inner road wheel to rise to a higher position. The height of the road wheel exceeds the limit height of the track induction tooth. The outer road wheel can be removed. Figure 3 shown.

[0030] c. Carry out corresponding project work according to different maintenance work:

[0031] ① If you want to replace the outer road wheel, remove the original outer road wheel fasteners and then remove the original road wheel, replace it with a new one and fasten it. Then start the vehicle and slowly move it forward (or slowly move it backward), stop the vehicle and brake it when the road wheel is completely on the track, and remove the road wheel wheel removal device.

[0032] ② If you replace the inner road wheel, remove the original outer road wheel fasteners, use a hydraulic jack to support the balance elbow, raise the jack until the lower edge of the inner road wheel exceeds the limit height of the track guide tooth, then remove the inner road wheel, replace it with a new one and tighten it.

[0033] ③If you replace the balancing elbow or torque shaft, first remove the road wheel, lower the height of the jack, and gradually lower the balancing elbow until the static stroke end. At this time, the balancing elbow reaches the initial installation position, and the torque shaft has no torque. The balancing elbow or torque shaft can be removed. After replacing the balancing elbow or torque shaft, follow the above steps a, b, c② to reinstall the road wheel.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
