[0026] The track special vehicle load wheel disc dismounting device is made of medium carbon alloy steel, has good rigidity and strength after heat treatment, and has a heat treatment hardness of HRC 40-45. Meanwhile, the track special vehicle load wheel disc dismounting device adopts a micro-nano zinc infiltration treatment process, and the surface zinc infiltration layer has a thickness of 0.06-0.09 mm, so that the device can be used for a long time without rust.

[0027] The track special vehicle load wheel disc dismounting device has the following use method:

[0028] a. First, the load wheel disc dismounting device is placed in front of the load wheel to be dismounted, at this time, the load wheel disc dismounting device is positioned on the track, the first supporting lug 2 is clamped between the two track end connectors, and the second supporting lug 3 is clamped between the two guide teeth, as shown in Figure 2 .

[0029] b. Start the vehicle and slowly move the vehicle forward, at this time, the inner side load wheel gradually approaches the load wheel disc dismounting device, and the load wheel gradually falls into the top end arc of the load wheel support seat main body 1, stop the vehicle and brake to extinguish. At this time, the load wheel disc dismounting device supports the inner side load wheel to be raised to a higher position, and the height of the load wheel exceeds the limiting height of the track guide tooth, so that the outer side load wheel can be dismounted, as shown in Figure 3 .

[0030] c. According to different maintenance work, corresponding project work is carried out:

[0031] ① If the outer side load wheel is replaced, the original outer side load wheel fastener is dismounted, and then the original load wheel is dismounted, a new load wheel is replaced and fastened. Then start the vehicle and slowly move the vehicle forward (or slowly move the vehicle backward), stop the vehicle and brake to extinguish when the load wheel completely falls on the track, and remove the load wheel disc dismounting device.

[0032] ② If the inner side load wheel is replaced, the original outer side load wheel fastener is dismounted, the oil pressure jack is used to press against the balance elbow, and the jack is raised to the position where the lower edge of the inner side load wheel exceeds the limiting height of the track guide tooth, so that the inner side load wheel can be dismounted, and a new load wheel is replaced and fastened.

[0033] ③ If the balance elbow or the torsion shaft is replaced, first, the load wheel is dismounted, the height of the jack is lowered, the balance elbow is gradually lowered until the static stroke end point, at this time, the balance elbow reaches the initial installation position, and the torsion shaft has no torque, so that the balance elbow or the torsion shaft can be dismounted. After the balance elbow or the torsion shaft is replaced, the above steps a, b and c are performed to re-mount the load wheel.

[0034] The above merely is the preferred implementation manner of the present application, and it should be noted that, for the ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and deformations can be made, and these improvements and deformations should also be considered as the protection scope of the present application.
