Anti-rollover device for use during loading and unloading of coal mine car

Abstract

The invention discloses an anti-rollover device for use during loading and unloading of a coal mine car. The anti-rollover device comprises a fixed frame, wherein the fixed frame is detachably arranged below a mine car track, and is provided with a holder; the holder comprises a left tumbler and a right tumbler correspondingly arranged on both sides of the track; one end of the left tumbler and one end of the right tumbler are provide with a collet respectively; the collets are in compression fit with the lower portions of a groove of a slant-legged channel steel with horizontal outward openings on both sides of a mine car chassis; the other end of the right tumbler is connected with a driving mechanism for driving the right tumbler to rotate; a right connecting rod is rotationally connected to a connecting shaft for connecting the right tumbler with the driving mechanism, and is rotationally connected with one end of a rocker arm which is rotationally connected to the fixed frame; the other end of the rocker arm is rotationally connected with a left connecting rod; the left connecting rod is rotationally connected with the other end of the left tumbler. By adopting the anti-rollover device, on-track fixed-point loading and unloading of the mine car can be realized. By compressing and limiting the slant-legged channel steel on the mine car chassis through the holder collets in a loading process, the mine car is prevented from rolling over. After loading is completed and materials are balanced, a rollover mechanism is opened.

Description

technical field [0001] The invention relates to a pneumatic anti-rollover device used for loading and unloading materials of coal mine trucks underground in coal mines. Background technique [0002] Due to the coal mine underground excavation working face, the coal mining face needs to transport a large amount of materials to the underground every day, and at the same time, a large amount of materials are transported from the underground to the wellhead. During the loading and unloading process, due to irregular material handling, such as block, rod 1. The size of the bagged materials is different, causing the center of the mine car to load and unload the material seriously deviated from the center of the mine car. Even if the same kind of loose materials are in the process of loading and unloading, due to the non-standard loading and unloading of the operators, the center of the mine car may be seriously deviated during the loading and unloading process. Great threat. The...

Problems solved by technology

Even if the same kind of loose materials are in the process of loading and unloading, due to the non-standard loading and unloading of the operators, the center of the mine car may be seriously deviated during the loading and unloading process. great threat

The safety of underground transportation and loading and unloading in coal mines, although all mining areas have attracted great attention and formulated strict transportation protection measures, none of them can fundamentally solve the problem

Due to the carelessness of the staff and the illegal operation, the safe loading and unloading effect is not ideal. The phenomena of mine cars rolling over, smashing feet, injuring hands, and squeezing the body in coal mines occur from time to time, which is not in line with humanized management. To reduce the rollover of mine cars The most effective and reliable way to damage the human body is to avoid the occurrence of rollover during the loading and unloading of mine cars
