Abstract

The invention relates to an arc-extinguishing carbon brush power-taking device, comprising: a casing, the casing includes a baffle plate and a carbon brush holder; The sliding hole is nested on the guide rail; an airtight cavity is formed between the housing and the guide rail, and an inert gas is filled in the airtight cavity; a carbon brush is fixed on the carbon brush On the inside of the brush holder, the carbon brushes are used to rub against the guide rails to collect electricity. The present invention reduces the probability of potential safety hazards from the two dimensions of reducing flammable and explosive gas and dust and reducing combustion-supporting gas, and improves the safety of the carbon brush power-taking device in use in an environment with poor ventilation conditions.

Description

technical field [0001] The invention relates to the field of carbon brush power-taking devices, in particular to an arc-extinguishing carbon brush power-taking device. Background technique [0002] At present, monorail suspension trolleys are widely used. In automated logistics systems, restaurant delivery, and hospital rail conveying devices, electric trolleys use carbon brushes to contact rails with power signals to pick up electricity through sliding connections. Electric trolleys are also Carbon brush power-taking device. The carbon brush power-taking method can be used normally in general occasions, but there is a great potential safety hazard in environments with poor ventilation conditions such as mine tunnels and cable trenches. This is mainly due to the poor ventilation environment of mine tunnels and cable trenches, where flammable and explosive gases and dust such as methane and swamp gas accumulate in the tunnels. Inflammable and explosive gas can cause catastr...
