Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an epoxy-coated seven-wire galvanized prestressed steel strand, which solves the problem that the steel strand proposed in the above-mentioned background technology directly contacts the ground during use and winding, causing the steel strand to The surface of the wire is easily worn by the ground during transportation, which reduces the joint degree and service life of the steel strand. Secondly, the general steel strand is not strong enough to be gathered, and it is easy to scatter when impacted by external forces.

Abstract

The invention discloses an epoxy coating seven-wire galvanized prestressed strand, and relates to the technical field of steel strands, in particular to a main rod, a rotating mechanism, a pushing mechanism and a fixing rod mounting mechanism, wherein a limiting mechanism is arranged on the left side and the right side of the main rod, the limiting mechanism comprises a side plate, a limiting column, a limiting groove and a disc frame, wherein one side of the side plate is welded to the main rod, the limiting column is integrally arranged on the other side of the side plate, the outer side ofthe limiting column is sleeved with the limiting groove, an annular steel strand is wound and distributed on the outer surface of the main rod, the rotating mechanism is positioned at the outer side of the disc frame, a supporting frame is fixedly arranged below the rotating mechanism, the pushing mechanism is positioned at one side of the lower end of the supporting frame, and the fixing rod mounting mechanism is positioned at the outer side of the annular steel strand. According to the epoxy coating seven-wire galvanized prestressed strand, a hydraulic cylinder, a hydraulic rod, a transverseplate, a pulley and a sliding rail are arranged to cooperate with each other, so that the device has strong flexibility, and the main rod with different lengths and diameters can be conveniently installed.

Description

technical field [0001] The invention relates to the technical field of steel strands, in particular to epoxy-coated seven-wire galvanized prestressed steel strands. Background technique [0002] The steel strand is a steel product composed of multiple steel wires. The surface of the carbon steel can be added with galvanized layer, zinc-aluminum alloy layer, aluminum-clad layer, copper-plated layer, epoxy resin, etc. according to the application. It can be divided into prestressed steel strands, (for electric power) galvanized steel strands and stainless steel strands. Among them, the prestressed steel strands are coated with anti-corrosion grease or paraffin and covered with HDPE. They are called unbonded prestressed steel strands. Stressed steel strands are also made of galvanized or galvanized aluminum alloy steel wire. [0003] The existing steel strands are in direct contact with the ground during winding, which causes the surface of the steel strands to be easily worn ...
