Intelligent self-moving device for secondary transfer of fully-mechanized coal winning machine

Abstract

The invention provides an intelligent self-moving device for secondary transfer of a roadheader, which is characterized in that two pairs of tail self-moving devices are symmetrically mounted on guide lantern rings on two sides of a guide rail, the angle between a prop column oil cylinder and a traction oil cylinder is adjusted by an adjusting oil cylinder until the prop column oil cylinder and the traction oil cylinder are vertical, a prop column oil cylinder telescopic rod of the prop column oil cylinder extends out to support a roadway top plate, and an anti-sinking oil cylinder supports the ground; after the tail is pushed forwards by a certain distance through a traction oil cylinder telescopic rod of the traction oil cylinder, a prop column oil cylinder telescopic rod of the prop column oil cylinder is retracted into a prop column oil cylinder barrel, the traction oil cylinder telescopic rod of the traction oil cylinder is retracted into a traction oil cylinder barrel, and a sliding sleeve is driven to move in a guide lantern ring; therefore, the purpose that the whole machine tail self-moving device moves forwards in a stepping mode is achieved, then the whole roadheader secondary conveying reversed loader is driven to move forwards automatically, the stepping self-moving function is achieved, guarding of a specially-assigned person is not needed, personal injury is reduced, and coal conveying efficiency is improved.

Description

technical field [0001] The invention belongs to the field of fully mechanized excavator equipment, in particular to an intelligent self-moving device for a fully mechanized excavator with two rotations. Background technique [0002] Fully mechanized excavator is the abbreviation of comprehensive mechanized excavator. It is a comprehensive mechanized equipment that integrates multiple functions of excavation, rock loading, coal transportation, even support, and nailing. The speed of excavation directly affects the working efficiency of fully mechanized excavator. , an important factor in determining the production capacity of coal enterprises. At present, most of the coal transportation devices in coal mines include fully-mechanized excavators, secondary transporters and transmission belt conveyors. The belt of the running loader is transported to the transmission belt conveyor, and the transmission belt conveyor transports the coal lumps to the coal bunker, thus completing ...

AI Technical Summary

Problems solved by technology

[0003] The tail movement of the existing two-run loader basically depends on the crawler roadheader or a single column manually used to fix the winch and then use the winch to move. The second line of the fourth page of the patent application CN 108868764 A specification discloses a tail movement method, the power walking part releases the twisted rope to the connection of the tail, and the butterfly buckle is connected. Pull the tail to a distance of 1000mm from the tail end of the power unit, loosen the twisted rope, remove the butterfly buckle, fix the front end of the extension tail with a ground anchor, and complete the tail movement process. This moving method is time-consuming and laborious, and requires manual control. , and if the direction of the twisted rope is not well controlled, it is easy to cause the entire tail to deviate, and the movement efficiency of the tail is low, resulting in slow excavation speed, less coal in excavation, and increased cost. The size of the blocks is different. During the transportation, the scattered coal blocks are easy to injure the handling personnel, which is extremely dangerous.
