Multi-purpose and Narrow-body Trackless Rubber Wheel Platform in Coal Mine

The multi-purpose trackless rubber platform and its hydraulic system have been researched and developed for coal mines. The special integrated frame was designed. Other components were connected with the frame by bolts, which is easy to be maintained. Based on the needs of working conditions in coal mine, through the comparative analysis of the demands and characteristics of conditions in the mine, the applicable full hydraulic systems were researched and developed. Through the analysis of working conditions and driving system, a full hydraulic braking scheme suitable for rubber vehicle was proposed. After assembling and debugging, the simulation test was carried out on the ground. The results show that the equipment has strong maneuverability, which has advantages of maximum width of 1.5 m, maximum speed of 20 km/h, steering flexibility and braking safety. The drilling and anchoring equipments can be installed on the cargo platform for corresponding construction work, or the cargo box can be installed for material handling.
