A crawler type underground coal mine car

Abstract

The invention discloses a crawler-type underground coal mine car, which comprises a fixed chassis, a storage bucket and a push-pull plate. The storage bucket is movably installed on the upper part of the fixed chassis, and two groups of hydraulic struts are movably installed between the storage bucket and the fixed chassis. , the push-pull plate is movably installed on the inner side of the storage bucket, the inner surface of one end of the push-pull plate is movably installed with a second card wheel, and the inner surface of the other end of the push-pull plate is movably installed with a third card wheel, the push-pull plate The inner surface of both ends is close to the bottom of the second and third locking wheels, and the first locking wheel is movably installed, and the outer surfaces of both ends of the push-pull plate are fixedly equipped with positioning buckles; so that the crawler underground coal mine car has The balance adjustment structure avoids rollover during transportation, and at the same time, it has an auxiliary discharge structure to avoid slag residue in the hopper of the crawler underground coal mine vehicle, and improve the use effect of the crawler underground coal mine vehicle.

Description

technical field [0001] The invention belongs to the technical field of coal mine vehicles, in particular to a crawler type underground coal mine vehicle. Background technique [0002] Coal mine car is a special vehicle for mine track transportation. It is a standard or narrow-gauge railway transport vehicle for transporting ore, waste rock and coal in mines. It is generally pulled by locomotives or winches. Flatbed trucks and material trucks specially designed for transporting materials; inclined shaft man-carts and flat lane man-carts for people. [0003] The comparative document CN210941749U discloses a coal mine car that is convenient for unloading, including a mounting frame and side baffles. Push handles are provided on the left and right sides of the car body, and trapezoidal plates are provided on the upper surface of the car body. At the same time, the trapezoidal plate The outer side is provided with a lighting lamp body, the side baffle is rotatably connected to t...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fixed structural design of the hopper of the traditional crawler-type underground coal mine vehicle, the user cannot perform balance adjustment operations on the coal mine raw materials in the hopper, which makes the crawler-type underground coal mine vehicle prone to rollover during the transportation project, thereby reducing The safety of the crawler-type underground coal mine vehicle is improved; at the same time, the traditional crawler-type underground coal mine vehicle does not have an auxiliary discharge structure, and the traditional crawler-type underground coal mine vehicle adopts a tipping bucket structure for coal mine discharge operation, so that the hopper of the crawler-type underground coal mine vehicle Residual phenomena are prone to appear in the interior, so that the user needs to manually clean the hopper of the crawler-type underground coal mine vehicle, which increases the user's operation steps; at the same time, the traditional crawler-type underground coal mine vehicle does not have multiple buffer protection structures, which reduces the The safety of the crawler type underground coal mine vehicle during driving operation, and a crawler type underground coal mine vehicle is provided
