Analysis of the Influence of Different Explosion-Proof Types on the Design of Coal Mine Robots
In order to reduce the size and weight of coal mine robots,and increase the walking and endurance capabilities of the robots,from the perspective of explosion-proof design,the influence of four common explosion-proof types,namely positive pres-sure,explosion-proof,oil immersion and sand filling,on the design of the robot was investigated respectively.Conducted a com-parative analysis.Taking 10 groups of randomly set typical rectangular robot cabinets as the research object,four methods of posi-tive pressure,explosion-proof,oil immersion and sand filling are adopted for explosion-proof design,and the volume and weight of the same cabinet after different explosion-proof designs are compared and analyzed.Variety.The results show that the four explosion-proof types of explosion-proof boxes are similar in size,but when the robot box size is small,the weight of the ex-plosion-proof box designed by the method of explosion-proof,oil immersion and sand filling is relatively small.As the size of the robot box increases,the weight of the positive pressure type box is the smallest,and the explosion-proof type has the largest weight.
