Explosion-Proof Design for Coal Mine Rescue Robots
The explosion-proof design for coal mine robots that are used to explore environment and rescue after coal mine disaster must be adopted. In order to carry out the explosion-proof design for coal mine robots reasonably, based on the analysis of coal mine robots and their explosion-proof design, the explosion-proof types for robots are studied on. The conclusions are as follows: (1) the mixed explosion-proof design including integrated and partial explosion-proof design can be adopted in the robots design; (2) protection types for robots mainly include flameproof enclosure, pressurized enclosure, intrinsic safety, and combination of them. Based on this, the explosion-proof structures of the mobile systems of a track-type robot and a rocker-type robot for coal mine environment exploration are introduced. According to the different structure of the two robots, the concentrated and dispersed flameproof enclosures are respectively designed for the track-type robot and a rocker-type robot. This paper can provide reference for the explosion-proof design for coal mine robots.
