Problems solved by technology

[0004] In the process of coating the retarding agent on the surface of the prestressed steel strand, the traditional device has the problem of uneven application of the retarding agent, which not only causes waste, but also has low processing efficiency; moreover, new ones must be injected after use. Adhesive slowing agent, causing the entire production line to stop working, reducing work efficiency

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments.

[0019] A device for coating the surface of prestressed steel strands with a slow bonding agent, such as figure 1 As shown, it includes a base frame 4, a cylinder 2 and an injection tube 13. The base frame is a frame structure, and a flat plate (not shown) is installed on the upper surface of the base frame. The cylinder tubes are two and The left and the right are arranged, and are fixed on the flat plate through the L-shaped bracket 3. The upper part of the cylinder is sealed and installed with the cylinder head 1; The agent cartridge is fixed on the base frame through two L-shaped brackets 11, and the nozzles 12 are coaxially sealed at both ends of the injection cartridge; Bottom of cylinder is communicated and installed together, and control valve 10 is all installed on these two pipelines;

[0020] In this embodiment, th...

Abstract

The invention relates to a device for coating surface of a prestressed steel strand with a slow binder. The device comprises a pedestal, cylinder barrels and an agent injecting tube, wherein the pedestal adopts a framework structure; the two cylinder barrels are fixedly mounted on the left side and the right side of the pedestal respectively; cylinder covers are mounted on the upper parts of the cylinder barrels in a sealed manner; the agent injecting tube is transversely mounted on the pedestal at the front part of the cylinder barrel on the left side; tube nozzles are coaxially formed in the two end parts of the agent injecting tube in a sealed manner; the bottom of the agent injecting tube and the bottoms of the two cylinder barrels are communicated through two pipelines respectively, and are mounted together; a control valve is mounted on each of the two pipelines; the cylinder covers are connected with an air pump through an air pipe; a pressure meter and a pressure regulating valve are mounted on the air pipe. The device is simple in operation, can control the air pressure and the flow, ensures continuous machining of a prestressed steel strand production line, not only improves the working efficiency and reduces wastes, but also uniformly coats a slow binder layer and effectively improves the quality of a slow-bond prestressed steel strand.

Description

technical field [0001] The invention belongs to the technical field of steel strand production, in particular to a device for coating the surface of a prestressed steel strand with an adhesive retarder. Background technique [0002] Steel strand is a product made of multiple steel wires twisted, and there are many types, such as prestressed steel strands for bridges, etc. Prestressed steel strands are made of 2, 3, 7 or 19 high-strength steel wires composed of stranded steel cables. [0003] At present, the surface of the prestressed steel strand is covered with a sheath, and the layer of retarding adhesive that can be solidified after a certain period of time is filled between the prestressed steel strand and the sheath. The retarding adhesive has anti-corrosion, The effect of prolonging the curing time. [0004] In the process of coating the retarding agent on the surface of the prestressed steel strand, the traditional device has the problem of uneven application of the...
