A Reversible Wire Tightener for Reducing Resistance

Abstract

The invention provides a resistance-reducing reversible tightener. In a shell, a gear is fixedly installed on a winch rotating shaft; a supporting rod is parallel with the winch rotating shaft and provided with a locking valve capable of rotating with the supporting rod as a rotating axis; the locking valve comprises a valve body formed by symmetrically splicing a pair of locking elbows of the same structure together; a locking handle is arranged on the top of the valve body; a locking handle strip-shaped hole is machined in an upper top plate; the locking handle penetrates out of the locking handle strip-shaped hole to reach the exterior of the shell; the locking handle is sleeved with a compression spring; the bottom end of the compression spring abuts against the valve body; the top end of the compression spring is connected to a spring isolation gasket; the locking handle is sleeved with the spring isolation gasket which abuts against the inner wall of the upper top plate; the locking valve is matched with the gear to be used for locking the gear; and a pulley shaft is further installed between a first side plate and a second side plate and provided with a fixed pulley. The engineering using cost is low. Use is convenient. Automatic locking is achieved, and the anti-slipping and anti-reversing functions are achieved.

Description

technical field [0001] The invention relates to a wire tensioner, in particular to a resistance-reducing reversible wire tensioner, which can be applied in the fields of lifting, rope tightening, rope control and the like. Background technique [0002] The bearing capacity of the steel wire rope in the existing wire tensioner determines the maximum load of the wire tensioner. The greater the load, the thicker the wire rope, the larger the radius of curvature of free bending, the larger the windlass and its auxiliary pulley, and the larger the volume and weight of the wire tensioner. It is inconvenient to move, install and use the large load tensioner. Contents of the invention [0003] Based on the problems existing in the prior art, the present invention proposes a reversible wire tensioner with reduced resistance, which overcomes the defect that the traditional wire tensioner cannot be locked and anti-slip by directly pulling the wire rope by hand alone, and at the same...
