Abstract
The utility model relates to a stepping-forward self-moving forepole of a mine laneway. The stepping-forward self-moving forepole comprises a hydraulic supporting mechanism and a suspension type stepping-forward traveling mechanism which is connected with the hydraulic supporting mechanism. The hydraulic supporting mechanism comprises a swinging block four-bar mechanism and a parallelogram mechanism. The swinging block four-bar mechanism is composed of a supporting arm, a telescopic arm, a cylinder barrel of hydraulic cylinders and a piston rod of the hydraulic cylinders. At least two cross bars are arranged on the supporting arm at intervals. The parallelogram mechanism is formed by the facts that two parallel arm fulcrum bars are arranged in an opposite side mode, and the telescopic arm and a parallel arm are arranged in an opposite side mode. Two ends of the cross bars of the supporting arm are respectively provided with one hydraulic cylinder which can stretch obliquely towards two side walls of the mine laneway. Supporting plates which can be contacted with the mine laneway are arranged at the extending end of the piston rod of the hydraulic cylinders. The stepping-forward self-moving forepole of the mine laneway is strong in adaptability, large in supporting intensity, easy to operate, and feasible. The hydraulic supporting mechanism stretches out obliquely through the hydraulic cylinders and then is contacted and connected with the side wall of the mine laneway, and thus connection fastness is enhanced.
