A trough belt conveyor used in a narrow and long roadway and a method of using the same

Abstract

The invention discloses a crossheading belt conveyor used in a long and narrow roadway. The crossheading belt conveyor comprises a belt conveyor head, a belt conveyor tail, a middle rack and a middle driving device arranged between the middle rack and the belt conveyor tail. The middle driving device comprises a support frame, a guide cylinder, a middle unloading cylinder and a driving cylinder. The support frame comprises a support roller beam, a cylinder beam and an under frame. The support roller beam is obliquely fixed to the upper end of the under frame. The cylinder beam is horizontally fixed to the middle of the under frame. The guide cylinder and the middle unloading cylinder are installed at the upper end of the cylinder beam. The support roller beam is provided with a plurality of upper belt support roller frames. The middle unloading cylinder is installed at one end of the support roller beam. The side face of the under frame is provided with a lower belt support roller. The problem of belt conveying length can be effectively solved through the middle driving device; a belt storage bin can be assisted to draw a belt along with forward extending of the roadway, and the belt released through forward moving of the conveyor tail is buffered; a power device is arranged in the middle of the belt conveyor, so that the tension borne by the belt in a long-distance operation process is also reduced.

Description

technical field [0001] The invention relates to a trough belt conveyor for mines, in particular to a trough belt conveyor used in a narrow and long roadway and a method of use, and belongs to the technical field of underground coal mine transportation. Background technique [0002] The feature of the stretchable belt conveyor along the trough is that it lays the full length at one time, and the tail of the conveyor is continuously retreated and the fuselage is shortened as the working face progresses during mining. For some narrow and long roadways, due to the long length of the roadway, the ordinary belt conveyor cannot complete the transportation of gangue in the whole roadway due to the limitation of its transportation distance. [0003] If another telescopic belt conveyor is installed, it will be very difficult to enter and install the equipment due to the narrow section of the roadway; as the tail of the telescopic belt conveyor moves forward, it will also be difficult ...

AI Technical Summary

Problems solved by technology

For some narrow and long roadways, due to the long length of the roadway, the ordinary belt conveyor cannot complete the gangue transportation of the entire roadway due to the limitation of its transportation distance.

[0003] If another telescopic belt conveyor is installed, it will be very difficult to enter and install the equipment due to the narrow section of the roadway; as the tail of the telescopic belt conveyor moves forward, it will also be difficult to replenish belts into the storage bins of the two belt conveyors; The overlapping of two telescopic belt conveyors not only makes the system complex and difficult to install, but also requires large capital investment and wastes costs
