Description

Technical Field

[0001] The invention belongs to the technical field of inner wall coating of electric power pipes, and specifically relates to a process and method for coating the inner wall of an electric power pipe with a metal structure with a functional coating. Background Art

[0002] Power pipe is a kind of pipe used to protect power cables. It can effectively isolate the current, prevent leakage and electric shock accidents, ensure the safety and stability of power transmission, resist the erosion of chemical substances such as acid, alkali, and salt, and is suitable for various complex soil and water quality environments. It is widely used in power engineering. The inner wall of the power pipe generally has a functional coating, which can effectively isolate the current, prevent the current conduction between the power cable and the pipeline, avoid leakage, short circuit and other safety accidents, ensure the safety and stability of power transmission, and ensure the safety of personnel and equipment. It can also protect the inner wall of the power pipe from corrosion and extend the service life of the pipeline. The coating is atomized by a spray gun and other equipment and then sprayed on the inner wall of the power pipe under pressure. Generally, a device with a nozzle is inserted into the inside of the power pipe, and the nozzle is moved in the pipe through mechanical or manual operation to spray the paint evenly.

[0003] When coating the inner wall of existing power pipes, usually several workers cooperate in loading materials, carry the power pipes to the vicinity of the coating equipment, and then place the pipes at the feeding end of the coating equipment by manual rolling or lifting. When unloading, workers wait at the discharging end of the coating equipment. After the coating is completed, the pipes are removed from the equipment and carried to the designated storage area or directly to the next step of construction. Manual handling is difficult and requires a lot of time and physical strength, which seriously affects the efficiency of loading and unloading, and thus affects the progress of the overall coating operation. In addition, the spray gun bracket of the traditional mechanical spray gun is a fixed structure. The distance between the spray gun and the pipe wall cannot be flexibly adjusted according to the pipe diameter or process requirements. The fixed distance may not meet the optimal film-forming conditions of different coatings, resulting in reduced adhesion between the coating and the pipe wall, and easy peeling or cracking after long-term use.

The power can be transmitted to the auxiliary wheel through the transmission belt, so that multiple connecting rods rotate at the same time.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention is designed with a matching automatic loading mechanism and an intermittent conveying mechanism. The positioning seat on the conveying seat can move the coated pipe fittings to the blanking plate, so that they can roll into the centralized receiving device or the loading position of the next processing equipment. At the same time, the positioning seat can also move the unprocessed pipe fittings to the processing position to spray the inner wall of the pipe fittings, thereby realizing automatic loading and unloading of the pipe fittings, significantly improving production efficiency and safety, keeping workers away from high-pressure spraying equipment and chemical coatings, and reducing the risk of poisoning and mechanical injuries; (2) The present invention is designed with an adjustable coating mechanism. The distance between the coating nozzle and the inner wall of the pipe can be adjusted. When spraying on the inner wall of a large-diameter pipe, the distance between the coating nozzle and the inner wall of the pipe can be appropriately increased to allow the atomized paint to better cover the large inner wall area. For small-diameter pipes, the distance between the coating nozzle and the inner wall of the pipe can be reduced to prevent excessive accumulation of paint, so that the device can quickly adapt to the diameters of different pipes. There is no need to frequently replace the coating nozzle or adjust the construction equipment. A longer length of spraying can be completed at one time without repeated spraying. At the same time, the paint adheres to the pipe wall at a suitable angle and speed, reducing the possibility of rebound and splashing and improving the utilization rate of the paint.

8. The method for applying a functional coating to the inner wall of a metal structure power pipe according to claims 1-7, characterized in that: The specific steps include: Step 1: A worker places a plurality of pipe fittings (16) in a discharge seat (31) so that they are arranged neatly, and starts the power supply of the servo motor (43). The output end of the servo motor (43) drives the driving wheel (41) to rotate, and the power can be transmitted to the auxiliary wheel (42) through the transmission belt (49), so that a plurality of connecting rods (45) rotate simultaneously. The rotation of the connecting rods (45) drives the positioning seat (48) on the transmission seat (47) to perform a circular motion; Step 2: The positioning seat (48) on the conveying seat (47) can move the unprocessed pipe (16) whose rolling tendency is blocked by the limit block (35) to the processing position, turn on the power of the electric telescopic rod (610), and the worker adjusts the position of the movable seat (64) according to the inner diameter of the pipe (16) to be processed.
