Movement trolley in downhole explosion-proof box body for coal mine

Abstract

The invention discloses a movement trolley in a downhole explosion-proof box body for a coal mine, aiming at the problem that the movement of an electric device in the downhole explosion-proof box body for the coal mine has dislocation easily in the transportation process. The movement trolley comprises an explosion-proof box body (4) and a movement trolley (3), wherein the inner bottom of the explosion-proof box body (4) is fixedly provided with a box body base plate (1); the front end of a guide rail set (2) is provided with a centering plate (6); a pair of centering holes (11) are arranged on the centering plate (6); a pair of centering axles (12) are arranged at the front end of the trolley body (17) of the movement trolley (3) and are in clearance fit with the centering holes (11) on the centering plate (6); a pushing bolt (16) is arranged at the lower part of the trolley body (17) of the movement trolley (3); a base plate (7) and a pushing seat (9) are arranged at the rear end of the guide rail set (2); and the pushing seat (9) is provided with a matching hole of the pushing bolt (16). According to the invention, the movement is combined with the box body firmly, thus the structure is simple.

Description

technical field [0001] The invention relates to a movable movement trolley in a casing of flameproof electrical equipment for mines. Background technique [0002] The installation of electrical components in explosion-proof cabinets in coal mines often adopts fixed or movable cores. When there are many and heavy electrical components, movable installations are often used. It is limited in a certain space, which brings difficulties to the installation of components and the assembly and debugging of the movement and the box. It often happens that it is difficult to debug in place at the assembly site. Collision damage and so on. Contents of the invention [0003] The invention provides a movement trolley in an underground explosion-proof box of a coal mine, which solves the problem that the movement is dislocated during the transportation process of the electrical components in the explosion-proof box of the coal mine, which causes collision damage to the components. [...
