Problems solved by technology

According to this, the materials, equipment, spare parts, etc. required for the excavation face need to be manually transported within a distance of at least 100m, and the weight of the equipment and materials is tens of kilograms or hundreds of kilograms. Manual transportation such as dragging is completed, and the efficiency is extremely low, especially the labor intensity of the workers, the harsh working conditions, and the hidden safety hazards are serious, threatening the personal safety of the workers at all times

Abstract

The invention discloses a mechanical carrying device of a fully mechanized excavation face, which is suitable for various coal mines. The mechanical carrying device consists of a main beam, a main beam suspension pulley, a carrying pulley, a main beam stepper oil cylinder, a hydraulic winch and a tension tail wheel. The hydraulic winch mounted at the front end tows a steel wire cable to pull the carrying pulley so as to move equipment and materials; the tail wheel at the back end uses a tension device for tensioning the steel wire cable to guarantee enough frictional force between the steel wire cable and a drum of the hydraulic winch; and the movement of the stepper oil cylinder realizes forward movement of the main beam. The device not only can solve the equipment and material carrying problem under various mining conditions and realize safe operation, timely braking and mechanical carrying, but also can relieve the physical labor of workers and guarantee the staff and equipment safety.

Description

technical field [0001] The invention relates to a mechanized handling device for fully mechanized excavation working faces in coal mines. The device can realize the mechanized handling of the back road transportation system of fully mechanized excavation working faces under various mining conditions in the mine, reduce labor intensity of workers, improve production efficiency, and realize fully mechanized excavation work. The mechanized handling of equipment and materials required by the surface ensures safe production. Background technique [0002] The equipment and materials required for the traditional fully mechanized excavation face are transported by the laid track. As the excavation progress increases, the distance from the end of the track to the excavation face gradually increases. According to regulations, the distance between the end point of track laying and the excavation face shall not be greater than 300m, and some enterprises stipulate that the distance shall...
