Unbonded steel strand steel wire separator

Abstract

The invention relates to an unbonded steel strand steel wire separator. The unbonded steel strand steel wire separator comprises a cone-shaped housing, separation blocks and handles, wherein an anti-skid bank is arranged in the cone-shaped housing; each separation block comprises separation holes and an oil collecting tank; the handles are symmetrically arranged at the small diameter end of the cone-shaped housing; the separation blocks are mounted in the cone-shaped housing to form the separation holes; the diameter of the separation holes is slightly greater than that of an unbonded steel strand steel wire. The handles of the separator is rotated in a countertwisting direction of the steel wire to move forward, the single steel strand steel wires are separated; oil stains on the steel wires are collected in the oil-collecting tanks, so that the oil stains are cleaned in a centralized manner, and the steel wires are further conveniently cleaned after being separated. The separator has the advantages of simple structure, convenience in manufacturing and operation, shortened construction time, safety and reliability and reduced pollution, and is suitable for an operation of eliminating oil stains for the unbonded steel strand steel wires.

Description

technical field [0001] The invention relates to the technical field of hydropower engineering, in particular to a device suitable for separating the steel strands and steel wires of the inner anchor section of the unbonded prestressed anchor cable. Background technique [0002] In engineering construction, prestressed unbonded anchor cables are often used for deep reinforcement and support of rock mass. The prestressed unbonded anchor cables are made of 1×7 high-strength and low-relaxation steel strands. The coating of unbonded steel strands The first layer is epoxy resin spray layer and special anti-corrosion oil stain coating, and the outsourcing PE sleeve prevents the oil stain of the coating from being corroded and spilled. In order to make the unbonded anchor cable body and the cementing material of the anchor section bond well, before weaving the anchor cable, it is necessary to peel off the PE casing of the anchor section in the anchor cable body, install the oil stop...

AI Technical Summary

Problems solved by technology

Each steel strand in the anchorage section is usually helically twisted by 7 bundles of steel wires. Before cleaning the oil stains on the steel strands, it is generally separated manually according to the reverse twist direction of the steel wires. When separating, it is not only time-consuming and labor-intensive, but also pollutes the environment. And the work clothes of construction workers, and there are potential safety hazards, which bring inconvenience to cleaning
