[0025] The utility model will be further described below in conjunction with the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, the brake valve disassembly auxiliary device of one embodiment of the utility model comprises a base 1, a fixing platform 2 and a locking assembly 3. The fixing platform 2 is arranged on the base 1, and the base 1 is an electromagnet. Figure 3 As shown, the fixing platform 2 is provided with a mounting groove 21 for mounting the locking assembly 3, and the locking assembly 3 includes a fixing claw 31, a movable ring 32 and a spring 33. Figure 2 As shown, the fixed claw 31 includes a plurality of movable claw petals 311. The movable ring 32 is sleeved on the fixed claw 31, and the spring 33 is arranged in the mounting groove 21. The top of the spring 33 is connected to the bottom surface of the movable ring 32, and the top surface of the movable ring 32 is in contact with the fixed claw 31. Figure 4 and Figure 5 As shown, the movable ring 32 has a first state in which it is not attracted by the base 1 and a second state in which it is attracted by the base 1. When the movable ring 32 is in the second state, the movable ring 32 moves to the lower part of the fixed claw 31 and opens the upper part of the fixed claw 31.

[0027] When the brake valve (not shown in the figure) is placed on the fixed platform 2, the fixed claw 31 in the locking assembly 3 can be inserted into the fixed hole of the brake valve. After the base 1 is powered on, a magnetic field is generated. On the one hand, the brake valve is attracted to be pressed against the fixed platform 2, and on the other hand, the movable ring 32 in the locking assembly 3 is attracted, so that the movable ring 32 overcomes the elastic force of the spring 33, moves downward in the installation groove 21 and interacts with the lower part of the fixed claw 31. Since the fixed claw 31 includes a plurality of movable claw petals 311, the action of the movable ring 32 on the lower part of the fixed claw 31 can cause the upper part of the fixed claw 31 to open, so that the fixed claw 31 is pressed against the wall of the fixed hole of the brake valve, and the locking effect is automatically achieved without manual operation. After the base 1 is powered off, the magnetic force disappears, the movable ring 32 returns to the initial position under the elastic force of the spring 33, and the upper part of the fixed claw 31 contracts, that is, unlocking is achieved. The brake valve disassembly auxiliary device of the utility model uses the magnetic force of the base 1 and the fixed claw 31 of the locking assembly 3 to realize the automatic fixing of the brake valve, which is efficient and stable.

[0028] Specifically, Figure 4 As shown, the claw flap 311 includes a locking portion 3111, a transition portion 3112 and abutting portion 3113. The locking portion 3111 is located outside the mounting groove 21, the transition portion 3112 is located between the locking portion 3111 and the abutting portion 3113, the first end of the abutting portion 3113 is connected to the transition portion 3112, and the second end of the abutting portion 3113 is located at the bottom of the mounting groove 21. When the movable ring 32 is in the first state, the movable ring 32 is sleeved on the transition portion 3112. When the movable ring 32 is in the second state, the movable ring 32 presses the abutting portion 3113. The various parts of the claw flap 311 play different roles respectively. The locking portion 3111 is used to lock the brake valve, the transition portion 3112 is used to limit the movable ring 32 so that it remains stable in the first state, and the abutting portion 3113 is used to interact with the movable ring 32 so that the locking portion 3111 is expanded outward to achieve locking of the brake valve.

[0029] Furthermore, the distance between the first end of the abutment portion 3113 and the groove wall of the mounting groove 21 is greater than the distance between the second end of the abutment portion 3113 and the groove wall of the mounting groove 21, so that each abutment portion 3113 forms a trumpet-shaped structure as a whole, and when the movable ring 32 moves downward, each abutment portion 3113 is synchronously retracted inward, so that each locking portion 3111 is synchronously expanded to achieve locking of the brake valve.

[0030] like Figure 4 As shown, when the movable ring 32 is in the first state, the upper portion of the fixed claw 31 is truncated cone-shaped. At this time, the top size of the fixed claw 31 is smaller, thereby being more convenient for the placement and positioning of the brake valve.

[0031] In this embodiment, the second end of the abutting portion 3113 is in an arc shape, so that after the abutting portion 3113 is squeezed by the movable ring 32 , the friction between the abutting portion 3113 and the bottom of the installation groove 21 is small, and the abutting portion 3113 can move more smoothly.

[0032] like Figure 4 and Figure 5 As shown, the surface of the locking portion 3111 is provided with a plurality of grooves 3114 to form anti-skid lines. Since the locking portion 3111 locks the brake valve relying on friction, by providing a plurality of grooves 3114 on its surface to form anti-skid lines, the locking portion 3111 can better lock the brake valve.

[0033] like Figure 1 As shown, a placement groove 22 for placing the brake valve is provided on the surface of the fixing platform 2. The placement groove 22 can limit the displacement of the brake valve in one direction, thereby improving the fixing effect of the brake valve.

[0034] Furthermore, a plurality of V-shaped grooves 23 are provided at the bottom of the placement groove 22 . The V-shaped grooves 23 are arranged densely, so that anti-slip patterns are formed on the surface of the fixing platform 2 , and the brake valve can be better fixed on the fixing platform 2 .

[0035] like Figure 6 As shown, another embodiment of the brake valve disassembly auxiliary device further includes a bearing platform 4 and a base 5, the bearing platform 4 is rotatably arranged on the base 5, the rotation axis of the bearing platform 4 is horizontal, and the base 1 is arranged on the bearing platform 4. The bearing platform 4 can swing on the base 5 to a certain extent, so as to facilitate the operation of various surfaces of the brake valve.

[0036] Furthermore, the base 1 is rotatably disposed on the bearing platform 4, and the rotation axis of the base 1 is vertical. The base 1 can rotate 360 ​​degrees, and combined with the rotation of the bearing platform 4, it is easier to operate on various surfaces of the brake valve.

[0037] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
