Description

Technical Field

[0001] The utility model relates to the technical field of mining vehicle cabs, in particular to a mining vehicle cabin door connecting device. Background Art

[0002] The working environment of mining vehicles is complex. In order to improve vehicle safety, the vehicle is equipped with a front anti-collision device. When the hatch is opened front and back, it is easy to collide with the front anti-collision device, resulting in the front hatch cannot be fully opened, the maintenance space is limited, and the maintenance time is long. At present, the hatch connection device of domestic mining vehicles mostly adopts the method of front and back opening, and the front anti-collision device is moved outward to ensure that there will be no interference with the hatch when it is opened. However, this design adjustment requires accurate calculation of the safe distance between the hatch and the anti-collision device, which is cumbersome and inconvenient to operate. Utility Model Content

[0003] In order to solve the problem of limited maintenance space due to the inability to fully open the mine vehicle hatch, the utility model provides a mine vehicle hatch connection device, which can open and close the hatch up and down without moving the front anti-collision device outward, thereby increasing the maintenance space and improving the convenience of maintenance.

[0004] In order to achieve the above object, the utility model provides a mining vehicle cabin door connection device, comprising:

[0005] Cover plate;

[0006] Two fixing brackets are installed at intervals on one side of the cover plate and are symmetrical about the vertical center axis of the cover plate;

[0007] A connecting component, one end of which is movably connected to the fixing bracket;

[0008] Two base mounting plates, the base mounting plates being connected to the other end of the connecting assembly;

[0009] Two telescopic struts, one end of each telescopic strut is connected to the connecting assembly.

[0010] It can be known from the above technical scheme that the utility model is connected to the fixed bracket through one end of the connecting component and to the base mounting plate through the other end; the connecting component is connected through one end of the telescopic strut, the telescopic strut gradually extends when the hatch cover is opened upward, and gradually contracts when the hatch cover is closed downward, thereby realizing the up and down opening of the hatch cover, and there will be no interference with the front collision prevention when opening, which is easy to operate and convenient to maintain.

[0011] Furthermore, the fixing bracket is L-shaped, and the bottom surface of the fixing bracket is fixedly connected to the cover plate. This solution improves the stability of the connection between the fixing bracket, the cover plate and the connecting component, and saves materials.

[0012] Furthermore, the connection component comprises:

[0013] Two upper connecting brackets, one end of each of the upper connecting brackets is connected to the upper end of the base mounting plate, and the other end is movably connected to the upper end of the fixed bracket;

[0014] Two lower connecting brackets, one end of the lower connecting bracket is connected to the lower end of the base mounting plate, and the other end is movably connected to the lower end of the fixed bracket.

[0015] The fixed bracket is connected to the base mounting plate through the upper and lower sets of connecting brackets, and then the fixed bracket is installed on the cover plate. It has high connection strength, the force is balanced and dispersed during the opening or closing process of the cover plate, and the connection is firm and stable.

[0016] Furthermore, it also includes a linkage rod, and the two ends of the linkage rod are respectively movably connected to the two upper connecting brackets. The beneficial effect of using the linkage rod is that the hatch cover moves together when opening or closing, ensuring that the force on both sides is uniform, and preventing the phenomenon of jamming caused by asynchronous movement of the two sides.

[0017] Specifically, the two telescopic struts are respectively connected to the upper connecting brackets in a one-to-one corresponding manner.

[0018] By adopting this solution, a stable movement trajectory can be maintained during the opening or closing of the cover, and the hatch cover can be accurately locked when it reaches the fully opened or closed position through the cooperation of the connecting bracket, the linkage rod and the telescopic support rod. The structure of this application is simple and reliable, providing the necessary mechanical strength, capable of withstanding various forces and pressures during the movement of the hatch cover, and ensuring that stable performance can be maintained after long-term use.

[0019] Through the above technical solution, the utility model achieves the following beneficial effects:

[0020] 1. The present application has a simple structure. When the hatch cover is opened upward, the telescopic strut gradually extends, and when the cover is closed downward, the telescopic strut gradually contracts, thereby realizing the up and down opening of the hatch cover, effectively solving the problem of small maintenance space of the hatch connection device of the mining vehicle, and improving the convenience of maintenance.

[0021] 2. The upper connecting bracket, the lower connecting bracket and the fixed bracket of the present application are movably connected, and the two ends of the linkage rod are movably linked to the two upper connecting brackets and cooperate with each other to maintain a stable motion trajectory during the opening or closing of the cover. The structure is simple and reliable, and provides the necessary mechanical strength. It can withstand various forces and pressures during the movement of the hatch cover, ensuring that it can maintain stable performance after long-term use. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Specifically, the fixing bracket 2 is L-shaped, and the bottom surface of the fixing bracket 2 is fixedly connected to the cover plate 1 by bolts and nuts, thereby improving the stability of the connection between the fixing bracket 2, the cover plate 1 and the connecting assembly 4 and saving materials.
