Abstract: In order to solve the problems caused by increased overall dimension of the drilling equipment with large capacity in underground coal mine, such as inconvenience of transportation and use in drill site, based on the thought of dividing the equipment of large capacity into various components, a new kind of drilling equipment-crawler mud pump vehicle for drilling in underground coal mine was developed. The pump unit was designed by calculating the input and output parameters, matching the performance of hydraulic motor of low speed and large torque, and the crawler pump integrates the key components such as crawler, control board and pump station. Finally, the industrial design based on ergonomics was completed for the crawler pump. The serialization of crawler pumps has broaden the application scope of this category of products, has important significance promoting the application of underground drilling equipment in aspect of coal mine safety such as gas drainage, water prevention and control, floor control and boreholes with large diameter and at high position.
