Abstract

The invention discloses a lifter special for a coal mine. The lifter comprises a conveying mechanism, a walking mechanism, a lifting mechanism and a controller for controlling the walking mechanism and the lifting mechanism. The walking mechanism does left-and-right motion along the conveying mechanism at the bottom end, the lifting mechanism moves up and down along the walking mechanism, a work platform is arranged at the top end of the lifting mechanism, the walking mechanism comprises a driving gear and a fixed frame, a hydraulic motor in transmission with the driving gear is arranged on a support, and the driving gear is meshed with a rack on the conveying mechanism. The lifting mechanism comprises a jack and a lifting connecting rod, and the jack is arranged in the lifting connecting rod. The lifter for the coal mine is simple in structure, fast in mounting and high in reliability, and important significance is achieved on the normal operation of a large mining height work face and the improvement of production efficiency.

Description

technical field [0001] The invention belongs to the field of mining machinery, in particular to a special elevator for coal mines. Background technique [0002] With the rapid development of the construction of the large mining height working face in underground coal mines, the hydraulic support of the large mining height working face can reach up to 7.2m, and the normal maintenance of the large mining height support becomes very difficult. Mine hydraulic lifting platform is a device for lifting and transporting items. [0003] At present, most hydraulic lifting platforms are not specially designed for mining to meet the needs of the mining industry. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a special elevator for coal mines with simple structure, small space occupation, safety and reliability. [0005] In order to solve the problems of the technologies described above, the technical solution adopted in t...
