  • Automatic straightening device and method for scraper conveyor on fully-mechanized coal mining face based on tensile and compressive force sensors
    Patent number: 10494925
    Abstract: An automatic straightening device includes a fully-mechanized coal mining working face, which includes a plurality of middle troughs, and each middle trough is connected to a push-pull rod of one hydraulic support. The fully-mechanized coal mining working face is provided with the automatic straightening device. The automatic straightening device includes a flexible element rope, the tensile and compressive force sensors, and a signal processing device. Each middle trough is provided with two tensile and compressive force sensors; one end of the flexible element rope is connected to a rope extend-retract control device, and the other end of the flexible element rope sequentially passes through lifting rings to be connected to the tensile and compressive force sensors and is fixed to a positioning force bearing bolt on the outermost side.
