[0017] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "back" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0020] The present embodiment relates to a device for debugging a pantograph airbag collar, which can solve the problem of difficulty in adjusting the front and rear collar positions of the airbag when installing and debugging the pantograph of a railway passenger car during maintenance.

[0021] Based on the above design concept, an exemplary structure of the device for debugging the pantograph airbag collar of this embodiment is as follows: Figure 1-2 As shown, it mainly comprises a circular ring 1 on which an arc-shaped slot 2 is opened; a bolt slot 3 is arranged in the middle of the arc-shaped slot 2; and a handle 4 is arranged on the outer wall of the circular ring 1 for easy holding.

[0022] Specifically, the size of the bolt slot 3 matches the size of the fastening bolt on the pantograph collar, that is, the bolt slot 3 can be sleeved on the fastening bolt on the pantograph collar.

[0023] There are four arc-shaped slots 2 , which are arranged along the circumference of the ring 1 . It can be understood that the number of the arc-shaped slots 2 can be increased or decreased according to actual needs.

[0024] There are four handles 4, and the four handles 4 are grouped in pairs. The positions of each group of handles 4 are symmetrical relative to the center of the ring 1, and the line connecting the two groups of handles 4 is vertical. The positions of the two handles 4 in each group are designed to be symmetrical relative to the center of the ring 1, and the line connecting the two groups of handles 4 is vertical. This allows the operator to remain stable when rotating the ring 1, further improving the debugging efficiency. The handles 4 in this embodiment are knurled handles 4 to increase the friction of the grip.

[0025] When the device for debugging the pantograph airbag collar of this embodiment is used, Figure 3-4 As shown, the bolt slots 3 on each arc-shaped slot 2 on the two devices are respectively put on the corresponding fastening bolts on the front and rear collars of the pantograph airbag to be debugged, and the symmetrical knurled handles are held with both hands. The positions of the front and rear collars of the pantograph airbag can be smoothly adjusted by using opposite forces on the two devices.

[0026] The device for debugging the pantograph airbag collar of the above implementation scheme can well achieve the rapid and accurate adjustment of the positions of the front and rear collars of the pantograph airbag, greatly improving the debugging efficiency and accuracy. By putting it on the fastening bolt and using the force in the opposite direction, the positions of the front and rear collars of the pantograph airbag can be easily adjusted, avoiding the tediousness and errors of the traditional debugging method; the device has a simple structure and is easy to operate.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
