Description

Technical Field

[0001] The utility model relates to the technical field of emergency tooling, in particular to an emergency driving tooling for a rail grinding vehicle, especially an emergency driving tooling for a GMC-96x rail grinding vehicle. Background Art

[0002] The hydrodynamic transmission box of the GMC-96x rail grinding vehicle is one of the most important components for the vehicle to run independently. When the hydrodynamic transmission box works normally, the vehicle can be controlled to run at a high speed. Its electric control valve is an important component for controlling the power output of the hydrodynamic transmission box. When faults such as valve jamming and power failure occur, it will immediately affect the independent running of the GMC-96x rail grinding vehicle.

[0003] In the existing emergency disposal methods, mainly manually press the electric control valve forcibly to keep the valve core pressed down. This method has great potential hazards in specific implementation. First, it needs to be pressed for a long time, and there are high-temperature components nearby, which has safety hazards. Second, when running at a high speed, 2 electric control valves need to be pressed simultaneously, and there is a possibility of improper operation on site. Summary of the Invention

[0004] The purpose of the utility model is to provide an emergency driving tooling for a rail grinding vehicle according to the deficiencies of the above-mentioned existing technologies. After being connected and installed with the electric control valve, when an emergency occurs, the locking pin is pushed down, and then the valve core of the electric control valve is forcibly opened to restore the independent running ability of the GMC-96x rail grinding vehicle.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] An emergency driving tooling for a rail grinding vehicle includes an electric control valve for driving control, and is characterized in that: it includes a body and a mounting seat. The mounting seat is connected to the electric control valve. A jack is arranged at the central position of the mounting seat. A retaining pin is provided at the bottom of the body, and the retaining pin is inserted into the jack. An L-shaped slot is arranged on the mounting seat, and a limit pin is arranged on the side wall of the body. The limit pin and the L-shaped slot cooperate to limit between the body and the mounting seat.

[0007] The cooperation between the limit pin and the L-shaped slot means that the limit pin enters from the vertical part of the L-shaped slot and further snaps into the horizontal part of the L-shaped slot, so that the body and the mounting seat are limited and fixed.

[0008] Two or more L-shaped slots are evenly arranged on the mounting seat, and two or more limit pins corresponding to the number and position of the L-shaped slots are arranged on the body.

[0009] The lower end of the mounting seat is provided with an external thread, and the top cover of the electric control valve is provided with an internal thread. The mounting seat is connected and fixed to the electric control valve through threaded cooperation.

[0010] The advantages of the present utility model are as follows: By means of the emergency driving tooling, the electric control valve of the crane is directly manipulated to work, avoiding the manual pressing operation under abnormal conditions, and improving the emergency efficiency and reliability of on-site operators during work; The device has a simple structure, is firmly and reliably installed, is easy to operate, and can quickly achieve emergency operation, providing reliable support for the emergency driving of the GMC-96x rail grinding vehicle.

[0017] The features of the present utility model and other related features are further described in detail below with reference to the accompanying drawings through embodiments for the understanding of those skilled in the same industry:

[0018] As Figure 1-6 shown, the marks 1-7 in the figure are respectively represented as: body 1, retaining pin 2, mounting seat 3, limit pin 4, L-shaped slot 5, mounting thread 6, and electric control valve 7.

[0019] Embodiment: As Figures 1 to 6 shown, the emergency driving tooling of the rail grinding vehicle in this embodiment mainly includes a body 1, a mounting seat 3, and an electric control valve 7. The electric control valve 7 is used to control the driving of the rail grinding vehicle, and the body 1 and the mounting seat 3 are used to control the state of the electric control valve 7, thereby controlling the driving state of the rail grinding vehicle.

[0020] Specifically, an external thread is provided at the lower end of the mounting base 3 for connection with the internal thread of the top cover of the electro-control valve 7. A jack is provided at the center position of the mounting base 3, and a pin 2 is provided at the bottom of the body 1. The pin 2 is inserted into the inside of the jack. An L-shaped card slot 5 is provided on the mounting base 3, and the top end of the vertical part of the L-shaped card slot 5 is opened at the end position of the mounting base 3; a limit pin 4 is provided on the outer wall of the body 1. The limit pin 4 can enter the card slot from the vertical part of the L-shaped card slot 5 and further be stuck into the horizontal part of the L-shaped card slot 5. At this time, the body 1 and the mounting base 3 are fixed in position by limiting.

[0021] During use, the mounting base 3 is threadedly connected to the electro-control valve 7, and then the body 1 is inserted. At this time, the pin 2 continuously moves downward in the jack of the mounting base 3, and the limit pin 4 moves downward synchronously with the L-shaped card slot 5 until the pin 2 pushes the valve core of the electro-control valve 7 downward to open the valve port of the electro-control valve, thereby connecting the action air circuit and enabling the power output device to work normally, and restoring the independent running ability of the rail grinding vehicle; at this time, the body 1 is slightly rotated to make the limit pin 4 be stuck into the horizontal part of the L-shaped card slot 5 to achieve locking, and the forced opening of the valve core of the electro-control valve 7 can be maintained.

[0022] Although the above embodiments have described in detail the concept and embodiments of the purpose of the present invention with reference to the drawings, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present invention without departing from the scope defined by the claims. Therefore, they are not elaborated herein one by one.
