Background

Along with the rapid development of automation and intellectualization of coal mines, the flexible and movable reversed loader and the carrying conveyor are more and more widely applied to a matched conveying system after tunneling, the moving distance and flexibility of the reversed loader, the moving flexibility of the tail of the carrying conveyor and the length of a storage belt directly influence the tunneling distance and efficiency of the mining all-in-one machine, and further the production capacity and efficiency of a coal face are determined to a great extent.

The working mode of the mining working face commonly used at present is that the mining integrated machine, the reversed loader and the crossheading belt conveyor are sequentially overlapped and matched with each other. The mining process is that coal is transferred to a crossheading belt conveyor by a transfer conveyor after being mined by a heading machine, and then transferred to a main conveying belt conveyor to be conveyed to a well through the crossheading belt conveyor. The length of the reversed loader lapped with the tunneling machine directly influences the tunneling distance of the tunneling machine, the tunneling machine can continuously work for a longer time as the length of the reversed loader is longer, and the tunneling efficiency is higher. At present, the length of a reversed loader used in the underground is about 30 meters, the tensioning stroke is short, the tensioning requirement can be met by adopting spiral tensioning, but the spiral tensioning cannot meet the tensioning requirement along with the increase of the length of the reversed loader, and therefore a new tensioning form is urgently needed to be researched and developed.

The reversed loader is generally in a modular joint unit structure in order to adapt to the complex ground environment in a coal mine, and all parts are hinged by using pin shafts to ensure that all units can rotate mutually, so that the head of the belt conveyor needs to be fixed in the operation process, the middle machine body is in a tensioned state, and the phenomena of ribbon floating and deviation caused by the rolling extrusion of all units of the machine body are prevented. The traditional machine head fixing mode mainly comprises wheel fixing and winch fixing, and the wheel fixing cannot provide enough self-locking force and cannot meet the requirements of long-distance and large-transportation-capacity belt conveyor tension; the winch fixing structure has the advantages that the installation space is large, the winch fixing structure cannot adapt to narrow space of an underground roadway, the underground working environment is severe, and the steel wire rope is extremely easy to corrode and has low safety factor.
