  • Mechanical constant-resistance single prop continuous prop lifting pre-tightening device and method
    Patent number: 10844717
    Abstract: A mechanical constant-resistance single prop continuous prop lifting pre-tightening device, structurally composed of a continuous prop lifting device, a pressurizing system, an oil supply line and a monitoring unit. The continuous prop lifting device is a core component, comprising a hydraulic cylinder, a prop barrel clamping sleeve ring and a prop rod clamping sleeve ring. The prop rod clamping sleeve ring is fixedly connected with a piston rod of the hydraulic cylinder by means of a cylinder head seat, and the prop barrel clamping sleeve ring is fixedly connected with a cylinder body of the hydraulic cylinder. With continuous pressurization of the pressurizing system, a cohesion occurs between the continuous prop lifting device and a prop rod, so that the prop rod of a single prop is lifted up to come into contact with a top plate and provide a pre-tightening force.
