Description

Technical Field

[0001] The present invention relates to the technical field of pipe network coating, and specifically provides a coating device for pipe network and its usage method. Background Art

[0002] A coating device for pipe network is a special device used to coat a protective coating on the inner surface of water supply pipe networks, heating pipe networks, boiler pipe networks, etc. Such devices form a uniform protective layer on the inner and outer walls of the pipes through advanced spraying, brushing, or electroless plating techniques;

[0003] For water supply pipe networks, coating can effectively prevent pipe corrosion, inhibit scale formation, and microbial growth, thus ensuring water quality safety and extending the service life of the pipes. In heating pipe networks, coating can reduce heat loss, prevent pipes from being corroded due to high temperature, improve heating efficiency, and reduce energy consumption. For boiler pipe networks, coating helps prevent fouling and carbon deposition, reduce pipe damage caused by high temperature and corrosion, and ensure the safety and efficiency of boiler operation;

[0004] In addition, coating can also reduce the roughness of the pipe network, reduce fluid resistance, and thus improve the conveying efficiency. These devices usually have a high degree of automation and precise coating thickness control capabilities to meet the requirements of pipe networks of different materials and sizes, ensuring the quality and performance of the coating;

[0005] During the process of coating the pipe network, when the pipe network enters the coating pool, there are a small number of bubbles adhering to the surface. During the coating process, if the small number of bubbles adhering to the surface are not treated, the pipe network at the position where the bubbles exist cannot be coated, thereby affecting the overall coating quality of the pipe network. Therefore, a coating device for pipe network and its usage method are proposed to solve the above problems. Summary of the Invention

The driving inner support claw includes a control shaft, a side groove is opened at one end of the control shaft, the other end of the control shaft is fixedly connected with a connecting shaft, one end outside of the connecting shaft is rotatably connected with a positioning circular plate through a bearing, the other end of the connecting shaft is fixedly connected with a support claw mechanism, and a power collection mechanism is installed outside the middle of the connecting shaft. The power collection mechanism includes a fixed ring shell, a clockwork spring is installed inside the fixed ring shell, and teeth are fixedly connected to the outside of the fixed ring shell at equal intervals in a circular shape.

[0009] As a further optimized content of the present invention, wherein: the positioning mechanism includes a positioning vertical plate, positioning horizontal plates are fixedly connected to both the upper and lower ends of the positioning vertical plate, the other ends of the positioning horizontal plates are fixedly connected to the inner wall of the coating tank, the included angle formed between the positioning vertical plate and the positioning horizontal plates is 90°, and the inner side of the upper end of the positioning vertical plate is arc-shaped.

[0010] As a further optimized content of the present invention, wherein: the movable tooth plate includes a positioning plate, a plurality of rotating plates are rotatably connected to the inner side of the positioning plate through a rotating shaft, bottom limiting shafts are installed at the lower ends of the rotating plates, and the bottom limiting shafts are fixedly connected to the inner wall of the positioning plate.

[0011] As a further optimized content of the present invention, wherein: the driving inner support claws, the auxiliary inner support claws, the movable tooth plate, and the positioning mechanism correspond to each other one by one, and a pipe network to be coated is installed between the driving inner support claws and the auxiliary inner support claws.

[0012] As a further optimized content of the present invention, wherein: the support claw mechanism includes a fixed shell, a column is fixedly connected inside the fixed shell, a telescopic spring is installed outside the middle of the column, and support claws are fixedly connected to both ends of the telescopic spring.

[0013] As a further optimized content of the present invention, wherein: there are two support claws installed inside any fixed shell, the support claws are slidably connected to the fixed shell, and the support claws are slidably connected to the column.

[0014] As a further optimized content of the present invention, wherein: the control shaft and the connecting shaft are coaxially arranged, the control shaft penetrates the bottom of the side clamping plate, and the positioning circular plate is fixedly welded to the side clamping plate.

[0015] As a further optimization of the present invention, there are two side clamps, the side clamps correspond to the linear motors one by one, the side clamps are parallel to each other, the angle between the side clamps and the lifting plate is 90°, and the middle of the upper end of the lifting plate is fixedly connected to the moving end of the lifter through a connecting piece and bolts.

[0016] As a further optimized content of the present invention, wherein: the interior of the clockwork spring is fixedly connected to the connecting shaft, and the interior of the fixed ring housing is rotatably connected to the connecting shaft.

[0017] As further optimized content of the present invention, step 1: pipe network installation: the pipe network to be coated is installed between the auxiliary inner support gripper and the driving inner support gripper. During the installation process, the support gripper is in close contact with the inner wall of the pipe network to achieve positioning of both ends of the pipe network;

[0018] In this process, the spacing between the side clamps is adjusted according to the length of the pipe network, and the spacing between the side clamps is adjusted by linear motor control;

[0019] Step 2: Pipe network into the coating pool: After the pipe network is installed, the lifting plate is driven up and down by the lifter to move the pipe network into the coating pool;

[0020] When the pipe network moves to the inside of the coating tank, the control shaft enters the position between the positioning vertical plates through the side grooves to be positioned so that the control shaft does not rotate when passing through the position between the vertical plates;

[0021] Then the teeth come into contact with the movable tooth plate, and in the process of moving downward, they continue to rotate, causing the spring set inside the fixed ring housing to deform;

[0022] When the end of the control shaft with the side groove is separated from the lower end of the positioning vertical plate, the pipe network continues to move downward, and the teeth are restricted by the movable tooth plate and cannot rotate. At this time, the clockwork spring is reset and drives the connecting shaft to rotate, thereby causing the pipe network to rotate at a high speed, which is used to eliminate bubbles attached to the inner wall of the pipe network;

[0023] Step 3: Finish coating: After coating is finished, the pipe network moves upward to leave the coating pool. During this process, the teeth move upward to control the rotation of the rotating plate, so that the spring cannot be deformed, and the positioning vertical plate continues to limit the control shaft to ensure the stability of the pipe network leaving the coating pool after coating is finished;

[0024] Step 4: Remove the pipe network after coating: After coating is completed, let it air-dry for a period of time, remove the pipe network from between the side clamps, and complete the coating process of the pipe network.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In the present invention, through the provided positioning mechanism, movable tooth plate and driving inner support gripper, energy is stored during the process of the pipe network entering the coating bath. When the pipe network moves to the bottom of the coating bath, through the stored energy, the pipe network rotates rapidly at the bottom of the coating bath, thereby eliminating the bubbles adhering to the surface of the pipe network, which can effectively improve the quality of the coated pipe network.

[0027] 2. In the present invention, through the provided support gripper mechanism, during the actual coating process, pipe networks with different inner diameters can be positioned. And during the installation process, the pipe network is directly placed between the auxiliary support gripper mechanisms, and by controlling the movement of the side clamping plates, the positioning of the pipe network can be completed, improving the convenience of installation.

[0028] 3. In the present invention, through the mutual cooperation of the movable tooth plate and the positioning mechanism, the rotation of the control shaft can be controlled at the required position. At the same time, after the coating is completed, the stability of the pipe network detaching from the inside of the coating bath can be effectively ensured, further improving the stability of the coating.

The middle of the upper end of the lifting plate 4 is fixedly connected to the moving end of the lifter through a connecting piece and a bolt. Through the above settings, the pipe network can be stably moved up and down inside the coating pool 1;

[0054] As a further technical solution for the implementation of this solution, the internal part of the clockwork spring 833 is fixedly connected to the connecting shaft 85, and the internal part of the fixed ring shell 831 is rotatably connected to the connecting shaft 85.

[0059] Then the teeth contact the movable tooth plate 3 and continue to rotate during the downward movement, causing the spring 833 disposed inside the fixed ring housing 831 to deform;

[0060] When the end of the control shaft 81 with the side groove 86 is separated from the lower end of the positioning vertical plate 21, the pipe network continues to move downward, and the teeth 832 are restricted by the movable tooth plate 3 and cannot rotate.
