[0010] Preferably, the extension direction of the slideway assembly is perpendicular to the axial direction of the subway hook, and includes two slide rails and a ball screw arranged between the two slide rails.

[0011] Preferably, the rear base includes a support plate, and two groups of support columns are symmetrically arranged at the bottom of the support plate, each group of support columns is slidably arranged on the two slide rails through a slider, and the bottom of the support plate is connected to the ball screw.

[0012] Preferably, the lifting frame is a diamond-shaped telescopic lifting structure.

[0013] Preferably, a control rod is provided in the middle of the diamond-shaped telescopic lifting structure.

[0014] Preferably, a handle is provided on the bottom plate.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This device can realize the lifting, nodding and swinging movements of the subway hook through the front ball head base and the lifting and left and right sliding structure of the rear component, which solves the defects of the existing hook installation tooling, improves the accuracy of the hook installation and removal, and brings convenience to the installation and removal of the hook.

[0017] 2. The lifting frame is a diamond-shaped telescopic lifting structure, and the lifting range can be controlled by a control lever, which is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0022] Example

[0023] like Figure 1 As shown, the present application proposes an auxiliary device for installing and removing a subway car hook, comprising a base plate 9 and a front component and a rear component arranged on the base plate 9 at a certain distance.

[0024] The front assembly is used to connect the front of the coupler, including a front ball base and a front clamp 3 arranged on the top of the front ball base. The outer contour of the front ball base is a cube, including a front base ball male head 2 and a front base ball female head 1 connected up and down.

[0025] The rear assembly is used to connect the rear of the coupler, and includes a slide assembly, a rear base 7, a lifting frame 5 and a rear clamp 4 which are arranged in sequence from bottom to top.

[0026] The extension direction of the slideway assembly is perpendicular to the axial direction of the subway hook, and includes two slide rails 8 and a ball screw arranged between the two slide rails 8 .

[0027] The rear base 7 includes a support plate, and two groups of support columns are symmetrically arranged at the bottom of the support plate. In this embodiment, each group of support columns is provided with two columns, and each support column is slidably arranged on two slide rails 8 through a slider, and the bottom of the support plate is connected to the ball screw 6.

[0028] The lifting frame 5 is a rhombus-shaped telescopic lifting structure, and a control rod is provided in the middle of the rhombus-shaped telescopic lifting structure.

[0029] A handle 10 is provided on the bottom plate 9 for easy movement.

[0030] When installing the coupler: clamp the front clamp 3 and the rear clamp 4 tightly to the front and rear of the coupler respectively, move the device to the designated position for installing the coupler, and complete the coupler installation by nodding, raising and swinging the head. The removal of the coupler is the reverse process of the installation action.

[0031] How to use this device:

[0032] 1. Lifting process: Use a ratchet wrench to operate the control lever to make the lifting frame 5 drive the rear part of the coupler to descend, and the front ball head base drives the front clamp 3 to tilt backward, so that the front part of the coupler is lifted, completing the process of lifting the coupler.

[0033] 2. Nodding process: Use a ratchet wrench to operate the control lever lifting frame 5 to drive the rear part of the coupler to rise, and the front ball head base drives the front clamp 3 to tilt forward, so that the front part of the coupler is lifted, completing the nodding process of the coupler.

[0034] 3. Swinging action: The ball screw 6 is twisted by a ratchet wrench, and the ball screw 6 drives the rear base 7 and the rear of the coupler thereon to move left and right on the slide rail 8, and the front ball head base also swings left and right, thereby realizing the swinging action of the coupler.
