Belt loader telescopic nose for coal mines

Abstract

The invention belongs to the technical field of downhole digging working face conveying equipment, particularly relates to a belt loader telescopic nose for coal mines, and solves the problems that the existing belt loaders for coal mines are in sufficient in rubber belt tensioning travel and difficult in belt deviation adjusting. The belt loader telescopic nose comprises a fixing frame on the rear portion. A slide frame is disposed in front of the fixing frame. A front guide rail and a rear slide groove are respectively arranged on at the front and the rear of the fixing frame. The slide frame is supported on the front guide rail through a front slider and in the rear slide groove through a rear slider. A drive rotary drum and a belt pressing rotary drum are mounted between the two lateral plates of the slide frame. Tensioning oil cylinders are respectively mounted on two sides of the fixing frame and the slide frame. The belt loader telescopic nose is compact in structure, good in rubber belt telescoping and tensioning effects by using the hydraulic cylinders, fast, safe, stable, reliable, and convenient to mount and use, and successful application of a belt loader with large transport volume and large span to coal mine downhole digging working face conveying equipment is achieved.

Description

technical field [0001] The invention belongs to the technical field of conveying equipment for tunneling working faces under coal mines, and in particular relates to a telescopic head of a belt transfer machine used in coal mines. Background technique [0002] Coal mine belt loader is widely used supporting equipment in coal mine roadway excavation operations. At present, due to the small conveying capacity and short lapping stroke of various belt loaders matched with roadheaders, most of them are driven by electric drums, and the tape tension adopts the mechanism form of screw nuts to pull and move electric drums and bolts to fine-tune the tail drum. . [0003] With the popularization and application of rapid excavation equipment such as continuous coal miner and integrated anchor digging machine in my country, higher requirements are put forward for the conveying capacity and conveying length of belt loaders used in coal mines, and the corresponding installed power increa...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of insufficient belt tensioning stroke and difficult belt deviation adjustment in the existing belt loader used in coal mines, the present invention provides a telescopic head of belt loader used in coal mines, which can realize the belt tensioning function and make the whole belt The machine fine-tunes the deviation of the belt by adjusting the tail drum, and then achieves the purpose of improving the performance of the belt loader, reducing the labor intensity of workers, reducing auxiliary working hours, and improving work efficiency.
