Description

Technical Field

[0001] This utility model relates to the field of PCCP pipe production technology, and in particular to a PCCP pipe winding and slurry impregnation device. Background Technology

[0002] PCCP (Prestressed Concrete Cylinder Pipe) is a high-performance pipe widely used in water conservancy projects and municipal water supply and drainage. The process of applying neat slurry to the wire-wrapped steel wire during its production is crucial. Traditional PCCP wire-wrapped steel wire coating mainly relies on manual spraying using a mud pump, but this method has many drawbacks. For example, the mud pump requires additional electricity, increasing production costs and wasting energy; manual spraying makes it difficult to ensure the uniformity of the slurry coating on the steel wire surface, potentially leading to corrosion during subsequent use and affecting the overall quality of the PCCP pipe; furthermore, the slurry needs to be mixed manually using a mixer, requiring continuous manual stirring, and the uniformity depends entirely on the worker. To address these issues, those skilled in the art have been seeking a more energy-efficient, high-performance, environmentally friendly PCCP wire-wrapped steel wire coating device that can guarantee coating quality. However, currently, no ideal solution that fully meets these needs exists on the market.

[0003] Therefore, it is necessary to develop a new type of PCCP tube-wound slurry coating device to overcome the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a PCCP pipe wire wrapping slurry dipping and coating device to address the above-mentioned problems, thereby solving the technical problems of uneven slurry coating on the steel wire surface, high labor costs, and high energy consumption in the traditional wire wrapping slurry coating process, which is achieved manually using a mud pump.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A PCCP pipe winding and slurry impregnation device includes a tank, a stirrer, and a slurry frame. The upper part of the tank is provided with an opening, and the stirrer is installed at the bottom of the tank. The slurry frame is attached to the tank and is provided with a plurality of pulley groups. Each pulley group includes at least one pulley, and at least one pulley group is located at the lower part of the tank. The winding wire passes through the plurality of pulleys and is wound onto the rotating PCCP pipe wall from the opening.

[0007] Furthermore, the coating frame includes a horizontal rod, a vertical rod, a first pulley assembly, and a second pulley assembly. The horizontal rod and the vertical rod form a T-shape and are mounted at the opening of the pool body. The vertical rod is vertically arranged below the connection between the horizontal rod and the vertical rod, and the lower end of the vertical rod is located at the lower part of the pool body. The first pulley assembly is mounted on the horizontal rod, and the second pulley assembly is mounted on the lower end of the vertical rod.

[0008] Furthermore, one side of the opening of the pool body is inclined outward, and the winding wire extends out along the outward inclined side.

[0009] Furthermore, the agitator includes a right-angle commutator, a stirring paddle, and a connecting shaft. The right-angle commutator is installed in the middle of the bottom of the pool body, the stirring paddle is installed at the output end of the right-angle commutator, one end of the connecting shaft is connected to the input end of the right-angle commutator, and the other end is used to connect to an external drive.

[0010] Furthermore, the side of the pool body is provided with a perforation, and a leak-proof sleeve is fixed on the perforation, through which the connecting shaft passes.

[0011] Furthermore, a coupling is provided at the through end of the connecting shaft.

[0012] Furthermore, a stepped ring is provided on the outer periphery of the leak-proof sleeve, and the stepped ring is fitted and sealed to the outer wall of the pool body.

[0013] Furthermore, the connecting shaft has several annular grooves in its middle section, and the annular grooves are located inside the leak-proof sleeve. A sealing ring is fitted inside the annular groove, and the outer edge of the sealing ring is pressed against the inner wall of the leak-proof sleeve.

[0014] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0015] 1. When using this utility model, the slurry is poured into the tank and stirred evenly by a stirrer; then the wire is passed through several pulleys so that it can be immersed in the slurry, thus achieving the coating of the wire. This solves the technical problems of uneven slurry on the steel wire surface, high labor costs, and high energy consumption in the traditional wire coating process, which is achieved by manually using a mud pump to spray the slurry.

[0016] 2. The stirrer of this utility model has an external connecting shaft, which can be driven by external force. In this case, the power to drive the PCCP pipe to rotate can be separated by existing technology to realize the rotation of the stirrer. The winding wire can be pulled by the power of the PCCP pipe rotation. That is, this utility model does not need to set up a separate drive, and can make full use of the movement of the original drive to further improve the energy utilization rate.

[0017] 3. This utility model can prevent the leakage of the paste by setting a leak-proof sleeve, thereby improving reliability; and by setting an outer opening, it can facilitate the winding of the wire to pass through the weapon at an angle. Attached Figure Description
