Big-gradient crossheading step-forward self-moving equipment train

Abstract

The invention belongs to the technical field of design and manufacturing of coal mine underground auxiliary transportation equipment in order to solve the transportation problem of a coal mine underground big-gradient crossheading roadway, and provides a big-gradient crossheading step-forward self-moving equipment train. The equipment train comprises a front anchoring, pulling and moving device, a middle anchoring, pulling and moving device, a rear anchoring, pulling and moving device, platform trolleys, advancing jacks and a pipe cable telescopic bearing system, wherein a front advancing jack is arranged at the front end of the front anchoring, pulling and moving device, the rear end of the front anchoring, pulling and moving device is connected with the platform trolleys through rear advancing jacks, the two ends of the middle anchoring, pulling and moving device are connected with the platform trolleys through the corresponding advancing jacks, the front end of the rear anchoring, pulling and moving device is connected with the platform trolleys through the corresponding advancing jacks, and the rear end of the rear anchoring, pulling and moving device is connected with the pipe cable telescopic bearing system through connecting rods. The train self-moving function, the walking deviation adjusting function, the pipe cable self-moving function and the like are highly integrated for the equipment train, and therefore the equipment train can step forward to move by itself when the gradient of the crossheading roadway is +/-25-degrees, slippage of equipment is effectively prevented, and it is guaranteed that the equipment train safely works in the big-gradient roadway.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of underground auxiliary transportation equipment in coal mines, and in particular relates to a large-slope self-moving equipment train along a trough. Background technique [0002] Most of the equipment trains currently used in mines are equipment trains pulled by traditional rail winches and steel wire ropes. When they move on large slopes, there is a phenomenon of self-slipping of the trains. The wire ropes are easily broken, causing sports cars and accidents. High labor intensity and low safety factor are recognized difficulties of domestic and foreign coal mining enterprises. Contents of the invention [0003] In order to solve the transportation problem of the large-slope tunnel roadway under the coal mine, the present invention provides a large-slope self-moving equipment train along the tunnel. [0004] The technical scheme that the present invention adopts is as follows:...
