Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described below with reference to specific embodiments shown in the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

It should also be noted that, in order to avoid obscuring the invention with unnecessary details, only the structures and/or process steps that are closely related to the solution according to the invention are shown in the drawings, while other details that are not relevant to the invention are omitted.

Referring to fig. 1 to 4, the following technical solutions are adopted in the present embodiment: the device comprises a supporting base 1, a fixed vertical beam 2, an upper lifting plate 3, a clamping embedding groove 4, a buffer spring 5, an axle slot 6, a wheel lifting disc 7, a counterweight bracket 8, a connecting shaft 9 and a counterweight component 10; the upper end of the supporting base 1 is connected with an upper lifting plate 3 through four groups of fixed vertical beams 2, the middle of the upper lifting plate 3 is provided with a clamping embedding groove 4, the middle of the supporting base 1 is connected with an axle slot 6 through a buffer spring 5, and the outer side of the axle slot 6 is connected with a wheel lifting disc 7 through the buffer spring 5; the outer sides of the left and right fixed vertical beams 2 are provided with counterweight brackets 8, and the inner sides of the counterweight brackets 8 are connected with counterweight components 10 through connecting shafts 9.

The clamping caulking groove 4 is of a U-shaped structure, and a plurality of clamping shifting pieces 11 are arranged on the outer side of the clamping caulking groove 4; the counterweight component 10 consists of a connecting rod 101, a balancing weight 102 and a lifting handle 103; a pair of balancing weights 102 are arranged at two ends of the lifting handle 103, and the outer sides of the balancing weights 102 are connected with a connecting rod 101; the axle slot 6 and the wheel lifting disc 7 are consistent with the wheel pair structure; the outer side of the counterweight block 102 is wrapped with a rubber protective shell.

The working principle of the specific embodiment is as follows: firstly, vertically hoisting a wheel pair to the middle of a wheel withdrawing tool through hoisting equipment, and clamping the wheel in a clamping embedding groove 4 through an upper lifting plate 3; meanwhile, the axle is protected through the clamping shifting piece 11, the buffer spring 5 and the axle slot 6 to prevent collision; after the vehicle is ready, the lower wheels are weighted, and the weight component 10 is placed on the surface of the lower wheels to ensure the gravity effect of the lower wheels; the oil injection and pressurization are carried out on the oil injection hole of the upper wheel, so that the upper wheel can be ensured to smoothly exit under the gravity action of the lower wheel and the counterweight device; the effectiveness based on vertical gravity reduces the wheels from pulling the axle during the exit; in addition, when the single-wheel disassembly mode is carried out, the binding belt feeding shaft is connected with the counterweight assembly 10, and gravity pressing matching oil injection is realized to finish disassembly.
