The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0023] like Figures 1 to 6 As shown in the figure, this application provides an anti-corrosion pipeline internal coating device, including a device body 1, a delivery pipe 6, a head end seat, and a traveling mechanism. The delivery pipe 6 is connected to the device body 1, and the head end seat is disposed at one end of the device body 1 opposite to the delivery pipe 6. The head end seat is provided with a nozzle 21 and a coating brush 18. The nozzle 21 communicates with the delivery pipe 6, and the coating brush 18 is located between the nozzle 21 and the delivery pipe 6, and the coating brush 18 is arranged circumferentially around the device body. The traveling mechanism is disposed on the device body 1, and the traveling mechanism has a plurality of rollers 12, which are arranged sequentially at intervals along the circumference of the device body 1.

[0024] The anti-corrosion pipeline internal coating equipment provided in this application is installed inside the pipeline during use. Multiple rollers 12 roll against the inner wall of the pipeline to support the coating equipment, ensuring the stability of the nozzle 21 and the application brush 18, and ensuring smooth movement of the equipment inside the pipeline. The coating material is then transported to the nozzle 21 through the delivery pipe 6 for spraying outwards. The equipment moves towards the head end seat, and simultaneously, the application brush 18 located between the top seat 14 and the front cover 19 evenly coats the coating material sprayed onto the inner wall of the pipeline. This achieves the effect of spraying and wiping evenly while moving, thereby improving the efficiency of pipeline internal coating and the uniformity of the anti-corrosion pipeline internal coating.

[0025] In some possible implementations, the traveling mechanism includes a sliding sleeve 8 and multiple movable linkage groups. The sliding sleeve 8 is slidably fitted onto the device body 1, and each of the movable linkage groups is arranged sequentially at intervals along the circumference of the device body 1. Each movable linkage group includes a first linkage 11 and a second linkage 10. One end of the first linkage 11 is hinged to the sliding sleeve 8, one end of the second linkage 10 is hinged to the device body, and the other end of the second linkage 10 is hinged to the first linkage 11. A roller 12 is disposed at the other end of the first linkage 11, and each roller 12 of the traveling mechanism is located within the same trajectory circle. The sliding sleeve 8 slides along the device body, driving the movable linkage groups to deform, thereby adjusting the diameter of the trajectory circle. Thus, this device can adapt to pipes of different diameters, adjusting the diameter of the trajectory circle formed by the multiple rollers 12 to be the same as the inner diameter of the pipe to be coated, enabling coating of the inner walls of pipes of different diameters.

[0026] In some possible implementations, the anti-corrosion pipe internal coating device includes a spring 15, which is sleeved on the device body. The two ends of the spring 15 abut against the head end seat and the sliding sleeve 8, respectively. The spring 15 facilitates automatic adjustment of the trajectory circle diameter. As the spring 15 abuts against the sliding sleeve 8, it moves away from the head end seat, maximizing the trajectory circle. When the device enters the pipe, the pipe's inner diameter is smaller than the trajectory circle diameter. The pipe's inner wall compresses the roller 12, causing the sliding sleeve 8 to move towards the head end seat and compress the spring 15, thus adapting the trajectory circle diameter to the pipe. Furthermore, the roller 12, under the elastic force of the spring 15, compresses the pipe's inner wall, ensuring more stable support for the entire device.

[0027] In some possible implementations, the walking mechanism includes a motor 13 mounted on the first link 11, and the motor 13 is kinetically connected to the roller 12 to drive the roller 12 to rotate.

[0028] When in use, the equipment is placed inside the pipeline, and then the roller 12 is driven by the motor 13 to rotate. The coating equipment can then move automatically inside the pipeline, further improving the automation of the equipment, increasing the efficiency of coating, and further reducing the need for manual labor.

[0029] In some possible implementations, a first hinge seat 9 is provided on the sliding sleeve 8, and a second hinge seat 7 is provided on the equipment body 1. The first connecting rod 11 is hinged to the first hinge seat 9, and the second connecting rod 10 is hinged to the second hinge seat 7, with the second connecting rod 10 hinged at the middle of the first connecting rod 11. The hinge seats on the first connecting rod 11 and the second connecting rod 10 connect the sliding sleeve 8 and the equipment body 1, resulting in a more stable connection and extended service life.

[0030] In some possible implementations, the headstock includes a top seat 14 and a front cover 19. The top seat 14 is disposed at one end of the device body, and the front cover 19 is disposed at the end of the top seat 14 opposite to the device body. The nozzle 21 is disposed on the front cover 19, and the application brush 18 is disposed on the top seat 14.

[0031] In some possible implementations, the headstock includes a retaining ring 16, and the applicator brush 18 is disposed on the retaining ring 16 and extends circumferentially along the retaining ring 16. The retaining ring 16 is located between the front cover 19 and the top seat 14. Fasteners pass through the retaining ring 16, the top seat 14, and the front cover 19 to connect and fix the retaining ring 16, the top seat 14, and the front cover 19. The applicator brush 18 is clamped between the top seat 14 and the retaining ring 16. The top seat 14 and the retaining ring 16 can be separated or clamped by removing and installing the fasteners, thereby allowing replacement with a new applicator brush 18 or an applicator brush 18 with different bristle lengths. An anti-slip pad 17 is provided on the inner side of the retaining ring 16.

[0032] In some possible implementations, a groove 20 is provided on the surface of the front cover 19, and the nozzle 21 is disposed within the groove 20. The nozzle 21 is disposed within the groove 20 and can be protected by the front cover 19 to prevent damage to the nozzle 21 from impact.

[0033] In some possible implementations, the front cover 19 has a conical shell with a plurality of grooves 20 spaced apart along the circumference of the device body 1, and each nozzle 21 is disposed in a corresponding groove 20. The side of the conical shell away from the device body 1 has a smaller diameter than the side closer to the device body 1, thus providing a guiding effect when the device enters the pipe, making the process of entering the pipe easier.

[0034] In some possible implementations, the anti-corrosion pipe internal coating device includes a pump body 5 mounted at one end of the device body 1, a delivery pipe 6 connected to the pump body 5, and the pump body 5 connected to each of the nozzles 21 via pipes located inside the device body 1. The pump body 5 delivers the coating material to the nozzles 21, which then spray it onto the inner wall of the pipe.

[0035] In some possible implementations, a base 2 is provided on the side of the main body away from the front cover 19, and multiple reinforcing ribs 3 are fixedly connected in a circular shape between the main body 1 and the base 2.

[0036] In some possible implementations, the anti-corrosion pipe inner coating device also includes a mounting base 4, which is connected to the base 2, and the base 2 and the mounting base 4 are fixedly connected by bolts and nuts.

[0037] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this application, thereby enabling those skilled in the art to better understand and utilize this application. This application is limited only by the claims and their full scope and equivalents.
