Explosion-proof automatic charging device suitable for mining inspection robot

Abstract

An explosion-proof automatic charging device suitable for a mining inspection robot comprises a charging plug and a charging socket. The charging plug comprises a plug flange base, a plug conical barrel type shell, a plug charging core, a plug insulating core and a plug explosion-proof door; the charging socket comprises a socket flange base, a socket flaring type shell, a socket outer cylindricalguide cylinder body, a socket inner cylindrical guide cylinder body, an annular sliding block, a thrust spring, a socket explosion-proof door, a socket insulation core and a socket charging core. Theplug explosion-proof door and the socket explosion-proof door are the same in structure and each comprise an insulating blocking disc, a blocking piece and a torsional spring, wherein a hinge shaft is fixedly arranged in the circle center of each insulating blocking disc, the center of each blocking piece is hinged to the corresponding hinge shaft and can rotate around the corresponding hinge shaft, the section of each blocking piece is triangular, and the bevel edge surface of the triangular section of each blocking piece abuts against the front end of the socket charging core; a charging core passing hole is formed in the insulating blocking disc; the torsion spring is fixedly installed on the insulation blocking disc; one end of the torsion spring abuts against the blocking piece, andthe other end of the torsion spring fixedly abuts against the insulation blocking disc through a blocking pin.

Description

technical field [0001] The invention belongs to the technical field of mine inspection robots, in particular to an explosion-proof automatic charging device suitable for mine inspection robots. Background technique [0002] Mine inspection robots are widely used in dangerous places such as coal mines that require explosion-proof grades to replace manual inspections, which is of great significance for reducing labor intensity, reducing labor risks, and improving production safety. [0003] However, since the operating power of the mining inspection robot is generally provided by the battery, when the battery is insufficient, it needs to be charged, and the current charging device used by the mining inspection robot does not have the explosion-proof function, so the mine The safety of the inspection robot is reduced when it is charging. Contents of the invention [0004] Aiming at the problems existing in the prior art, the present invention provides an explosion-proof auto...
