[0002] The mine hoisting system is an important part of the mine production process. The frequency of sports car accidents during the operation of the inclined shaft track hoisting system is relatively high. The most harmful accident in mine inclined shaft rail transportation is the sports car accident; the inclined shaft track sports car accident , mainly refers to the situation where the vehicle breaks away from the mechanical traction device (winch, winch) and rushes into the underground mine under the action of its own gravity on the upper parking lot of the inclined shaft or on the inclined road; In addition to the cables, air pipes, water pipes and other facilities in the alley, the operators will be injured or killed, resulting in personal injury accidents; so in order to provide transportation safety for underground coal mines, it is necessary to provide a new structure of coal mine transportation ground gear. very necessary

The invention belongs to the technical field of underground coal mine transportation safety and in particular relates to a coal mine transportation ground stopper device. The invention is mainly to provide a novel coal mine transportation ground stopper device to effectively avoid serious dangers caused by derailing accidents to underground working. The coal mine transportation ground stopper device mainly comprises two vertically and symmetrically placed vertical brackets; sliding grooves are symmetrically formed in the two vertical brackets; a buffering car stopping frame is arranged betweenthe vertical brackets; horizontal lifting beams are arranged at the upper ends of both the two vertical brackets; pulley blocks consisting of fixed pulleys and movable pulleys are symmetrically arranged on the horizontal lifting beams; one ends of steel wire ropes are connected with the buffering car stopping frame; the other ends of the steel wire ropes are connected with counterweight blocks whose weights are matched with the weight of the buffering car stopping frame; the counterweight blocks are arranged on elastic adjusting seats; and lever adjusting frames are also arranged on the elastic adjusting seats. The coal mine transportation ground stopper device has the advantages that the labor intensity of workers is effectively reduced, the enterprise production efficiency is enhanced,and the safety working environment of underground working is improved.
