In the assembly or maintenance of the braking system, the disassembly of the sensing valve cover is an indispensable part.

[0003] However, the current operation method mainly relies on fixing the valve body and using a pipe clamp to assemble or disassemble the valve cover. This operation method often encounters problems such as unstable clamping of the pipe clamp and loose valve cover in actual applications, resulting in cumbersome and inconvenient operation and greatly consuming the operator's physical strength and endurance. Utility Model Content

[0004] In order to solve the problem in the prior art that the current disassembly method is mainly to fix the valve body first and then use a pipe clamp to disassemble the valve cover, but this method often encounters problems such as unstable clamping of the pipe clamp and loose valve cover, the present application provides a sensor valve cover disassembly tool dedicated to railway freight cars to solve the above problems.

[0005] In order to achieve the above purpose, the technical solution adopted in this application is:

[0006] A sensor valve cover disassembly tool dedicated to a railway freight car comprises an air wrench and a disassembly tool, wherein the disassembly tool comprises a sleeve component, a ferrule component and a plurality of ratchet components;

[0009] As a further improvement of the utility model, a plug-in hole penetrating through the sleeve shell is provided inside the connecting seat, and the driving shaft of the wind wrench is plugged into the plug-in hole.

[0010] As a further improvement of the present invention, a first fixing hole is opened on the end face of the sleeve shell, and the clamping sleeve component is screwed to the first fixing hole by a bolt, wherein the screw rod of the bolt fixed on the end face of the sleeve shell is in sliding contact with the first fixing hole.

[0011] As a further improvement of the present invention, the end surface of the sleeve shell facing away from the wind wrench is further provided with a plurality of receiving grooves corresponding to the number of the pawl components, wherein a step is formed between each of the receiving grooves and the mounting groove, and the pawl component rests against the inside of the receiving groove and the step.

[0012] As a further improvement of the present invention, the sleeve component includes a base plate component and a chuck component, the base plate component includes a bottom end plate, a plurality of clamping grooves are provided on the circumferential outer wall of the bottom end plate, and the chuck component includes a chuck seat, and an extension portion of the end face of the chuck seat is clamped and fixed to the clamping groove.

[0013] As a further improvement of the present invention, the end surface of the bottom end plate is further provided with a plurality of second fixing holes, the positions of the second fixing holes correspond to the positions of the first fixing holes, and one end of the bolt is fixedly connected to the second fixing hole.

[0014] As a further improvement of the present invention, a plurality of guide grooves corresponding to the number of the pawl components are provided between the extension portion of the chuck component and the bottom end plate, and the pawl components are inserted into the guide grooves.

[0016] Compared with the prior art, the technical solution provided by the utility model has the following advantages and effects:

[0017] 1. In the present application, the wind wrench provides power to drive the disassembly tool to rotate, and the resulting rotational force acts on the sleeve component. The sleeve component then transmits this force to multiple pawl components, applying the necessary compression and rotational force to the pawl components, thereby realizing the self-tightening function, effectively holding the valve cover, and achieving the desired effect of tightening or loosening. In this process, a certain angle of relative rotation is allowed between the sleeve component and the ferrule component to ensure the flexibility of operation. At the same time, during the tightening process, the pawl component will gradually extend inward along the guide groove inside the ferrule component and gradually shrink to achieve tight compression of the valve cover. Through the continuous rotation of the sleeve component, the required clamping force can be continuously provided, thereby effectively reducing the labor intensity and improving the convenience of use. As the rotational movement continues, the pawl component gradually penetrates and fits tightly to the surface of the valve cover under the guidance of the ferrule component. This tight fit not only ensures the stability of the valve cover, but also avoids the sliding or dislocation that may occur during operation. BRIEF DESCRIPTION OF THE DRAWINGS
