Mine Electric Monorail Crane

Abstract

The invention relates to an electric hoist, and particularly relates to a mining power-driven monorail crane. The mining power-driven monorail crane comprises an arched support, suspending beams, an anti-explosion magnetic starter, an anti-explosion electric hoist and a driving device, wherein the suspending beams are arranged at the top of the arched support, the design method that collecting chains and a track are connected into a whole is adopted, upper and lower supporting plates and connecting pin shafts can form the chains, and the upper and lower supporting plates are processed with holes; the connecting pin shafts pass through the holes so as to connect the two supporting plates together, the distance between the pin shafts is designed to be pitch of a chain wheel, a power output gear of the driving device is mutually meshed with the connecting pin shafts of the chains, and the anti-explosion magnetic starter, the anti-explosion electric hoist and the driving device can operate on the lower supporting plate of the suspending beams through an auxiliary walking trolley and a driven trolley. The mining power-driven monorail crane provided by the invention has the advantages that the design is reasonable, the structure is simple, the cost is low, and the mining power-driven monorail crane is economical and practical.

Description

technical field [0001] The invention relates to an electric hoist, in particular to an electric monorail crane for mining, which is used for transporting equipment and materials in the initial stage of coal mine roadway excavation. Background technique [0002] When tunneling underground in coal mines, since it is not suitable for laying tracks for material transportation at the initial stage of tunneling, the U-shaped steel and other auxiliary materials used to support the tunnel can only be carried to the work site by the workers on their shoulders and hands, and the labor intensity of the workers is very high. . Later, in order to reduce the labor intensity of workers, relevant technicians designed and manufactured electric monorail cranes for mines. The structure of this monorail crane mainly includes walking mechanism, track, power hoist and control mechanism. The track is hung on the top of the roadway by I-beam, and a rack is set on the I-beam. The gear on the power ...

AI Technical Summary

Problems solved by technology

[0003] But in use, it is found that this monorail crane has some shortcomings, because its transmission mode mainly drives the traveling mechanism through the meshing of the gear and the rack. Both have undulations and bends, and the pinion and rack drive becomes quite difficult to deal with these undulations and bends

Although this difficulty is not insurmountable, it is just that when manufacturing these horizontally curved and vertically curved racks, the technical difficulty is large, the cost is high, and the cost is expensive, so it is not suitable for promotion

Moreover, the I-beam used for hanging is relatively easy to manufacture when it is bent horizontally, but it is more difficult to process it when it is bent vertically, and its bending radius is not easy to control.
