At present, explosion-proof trackless rubber wheel transporter is one of the most widely used underground auxiliary transportation equipment in major coal mines, to meet the urgent needs of more and more underground auxiliary transportation equipment. However, the explosion-proof trackless rubber wheel transporter is generally not flexible when loading and unloading drainage equipment, and often needs to be pulled and carried. The operation is not convenient, and it cannot meet the time requirements of emergency drainage pump handling, and there are serious safety risks. A new type of coal mine emergency rescue drainage pump truck is designed, which uses the antimetrical pull rod steering mechanism and straddling frame, and solves the technical problems that the conventional explosion-proof trackless rubber wheel transport truck is not flexible in handling drainage equipment and cannot handle large submersible electric pump. The experimental results show that the anti-symmetric tie rod steering mechanism can make the vehicle steering more flexible, realize the figure-shaped steering, reduce the tire wear and improve the service life of the tire. The riding straddle-type frame can obviously improve the safety factor of the vehicle load. The simulation results show that the safety factor of the frame is up to 4.0 under full load static condition, Also,the intensity of Steering mechanism and Suspension meet the requirement.
