Abstract
The utility model relates to a mechanical elevation type hydraulic pressure brace strut. Mine monomer hydraulic pressure brace struts widely used in mining roadway engineering by our country and the world at present are all outer injection type hydraulic pressure brace struts, and have low intensity, easy breakage, low setting pressure, bad top-cut effect, bad stability, easy detruding, great repair volume and great labour intensity. Efflux emulsion pollutes water source, the energy consumption is high, the flexibility is bad, the service life is short, the cost is high, and the utility model can not stand impinging corrosion of blasting mining conditions. The components of the utility model comprises a hydraulic pressure constant-resistance oil cylinder (1), and both sides of an end cover of the hydraulic pressure constant-resistance oil cylinder (1) are respectively provided with hydraulic pressure constant-resistance valves (2); the hydraulic pressure constant-resistance valves (2) are connected with a liquid complement valve (3); a pressuring mechanism is arranged in the oil cylinder; the pressuring mechanism is connected with a piston (11); and the piston (11) is connected with a movable strut (12). The mechanical elevation type hydraulic pressure brace strut is applied to coal mine roadway.
