Problems solved by technology

Electric drive requires an external power supply, which is less safe for the complex environment of coal mines
The hydraulic motor needs to be driven by special hydraulic oil, and a set of hydraulic oil supply system is required. The structure is relatively complicated. If the hydraulic motor is driven by emulsion, the internal corrosion of the motor will be serious, which will shorten the service life

Abstract

The invention relates to an emulsion cylinder crane walking device, belonging to the technical field of crane walking device; the technical problem to be solved is to provide an emulsion cylinder crane walking device with good safety and simple structure so as to lead cranes under the coal mine to continuously walk for a long distance, wherein a first rack and a second rack are respectively arranged on the upper portion and the lower portion of a frame in a parallel manner; the frame vertically moves under control of a lifting hydraulic cylinder so that a gear is meshed with the first rack or with the second rack; a retractable hydraulic cylinder controls the moving direction of the frame so that the racks drive the gear meshed therewith to rotate; the gear is fixed on a cantilever axle and rotates to drive a crane roller mounted on the cantilever axle to rotate; the crane roller rotates to drive the crane to walk; both the lifting hydraulic cylinder and the retractable hydraulic cylinder employ the existing emulsion pressure system in the coal mine as power; and the emulsion cylinder crane walking device is used for walking of cranes.

Description

technical field [0001] The invention relates to a crane traveling device for an emulsion tank, belonging to the technical field of crane traveling devices. Background technique [0002] At present, the driving modes of cranes in underground coal mines mainly include electric drive and hydraulic motor drive. Electric drive requires an external power supply, which is less safe for the complex environment of coal mines. The hydraulic motor needs to be driven by special hydraulic oil, and a hydraulic oil supply system is required. The structure is relatively complicated. If the hydraulic motor is driven by emulsion, the internal corrosion of the motor will be serious, which will shorten the service life. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art, and the technical problem to be solved is to provide an emulsion cylinder crane traveling device with good safety and simple structure, so as to realize the continuous long-distance ...
