[0002] In various fields, the carriers of various media are pipelines. According to different requirements, the materials, models and specifications of pipelines are different. For carbon steel seamless pipes and carbon steel welded pipes, they are directly stored under atmospheric conditions after production. Due to the humidity in the air, at the appropriate temperature, the pipeline wall will rust. By grinding and removing the rust on the outer wall of the pipeline and spraying anti-corrosion coatings, the corrosion degree of the pipeline can be reduced and the service life of the pipeline can be guaranteed.

[0003] The existing Chinese patent document publication number CN217615554U is a spray device for processing construction pipes. After the angle of the connecting rod changes, the nozzle can switch between the state of being close to the rotating head and the state of being far away from the rotating head, so that it works in the spraying state and the drying state. The nozzle in the spraying state is away from the pipe wall and sprays rust remover on the pipe wall, and the nozzle in the drying state is close to the pipe wall and sprays a drying airflow to dry and shape the rust remover.

[0004] However, in the process of implementing the above technical solution, it is found that the above technical solution has the following technical problems:

[0005] The existing spraying device for processing building pipes switches the spray head between spraying and drying states by changing the connecting rod angle to remove rust from the inner wall of the pipe. However, for the outer wall of the pipe, the use of the spray head easily causes paint waste and reduces the efficiency of spraying. Utility Model Content

[0006] In order to overcome the shortcomings of the existing spraying devices for processing building pipes, which easily cause paint waste and reduce spraying when processing the outer wall of the pipe, the embodiment of the present application provides a pipe outer wall rust removal nozzle, which is formed by setting the heating seat into an arc shape and sleeved on the outside of one end of the nozzle, and using the first hydraulic push rod to push the support shaft frame to drive the motor, and the spray arm is extended to the inside or outside of the pipe, and the heating seat is rotated on the outside of the nozzle, so that the multiple injection ports on the inner and outer arc surfaces of the heating seat are connected with the multiple liquid outlets on the nozzle, and then the control part is controlled by the second hydraulic push rod to make the nozzle slide under the support of the sliding seat, and the spray arm can be controlled by the motor to drive the nozzle to rotate, and the first hydraulic push rod can be controlled by the existing technology to drive the support shaft frame to rotate, so as to facilitate the spraying work between the inner and outer walls of the pipe, with small paint loss and improved spraying efficiency by rotary spraying.

[0023] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0024] Embodiment 1:

[0025] This embodiment introduces a specific structure of a pipe outer wall rust removal nozzle. Figure 1-Figure 3 As shown, it includes a nozzle 9 and a heating seat 12 disposed outside one end of the nozzle 9, a plurality of liquid outlets 17 are processed inside the other end of the nozzle 9, and a plurality of injection ports 11 are processed at the bottom and the top of the heating seat 12;

[0026] The axes of the plurality of liquid outlets 17 overlap with the diameter line of the nozzle 9. When the heating seat 12 rotates outside the nozzle 9, so that the plurality of injection ports 11 at the top or the plurality of injection ports 11 at the bottom correspond to the plurality of liquid outlets 17 one by one, the paint transported to the inside of the nozzle 9 can be sprayed from the liquid outlet 17 to the outside through the inside of the injection ports 11.

[0027] Secondly, in order to reduce the loss of paint during the painting process of the heating seat 12 using multiple injection ports 11 and ensure the spraying effect, Figure 1 As shown, the heating seat 12 is an arc-shaped plate. When spraying the inner wall of the pipeline, the outer arc surface of the heating seat 12 is switched to the bottom of the nozzle 9, so that the heating seat 12 adapts to the inner wall of the pipeline. When spraying the outer wall of the pipeline, the inner arc surface of the heating seat 12 is switched to the bottom of the nozzle 9, so that the heating seat 12 adapts to the outer wall of the pipeline on the outside of the pipeline.

[0028] like Figure 1 As shown, a spray arm 4 is disposed outside the spray pipe 9, a support shaft frame 2 is disposed on one side of the spray arm 4, a first hydraulic push rod 1 is assembled and connected to one end of the support shaft frame 2, and a motor 3 is assembled and connected to the inside of the other end of the support shaft frame 2;

[0029] Among them, by making the rotating shaft of the motor 3 pass through the inside of the support shaft frame 2 and be assembled and connected with one end of the spray arm 4, when the first hydraulic push rod 1 pushes the support shaft frame 2 to drive the motor 3 and the spray arm 4 is extended into the inside of the pipeline, the motor 3 is used to control the spray arm 4 to drive the nozzle 9 and the heating seat 12 to perform rotary spraying;

[0030] At the same time, when the heating seat 12 is located outside the pipeline, the first hydraulic push rod 1 is controlled by the prior art to drive the support shaft frame 2 to rotate, and the motor 3 is stopped, and the nozzle 9 and the heating seat 12 perform the rotation spraying work on the outer wall of the pipeline;

[0031] Secondly, in order to enable the nozzle 9 to drive the heating seat 12 to switch between the inside and outside of the pipe, so as to spray the inner and outer walls of the pipe, Figure 1 and Figure 2 As shown, the middle of the nozzle 9 is sleeve-connected with a control member 10, the top of the control member 10 is assembled with a second hydraulic push rod 5, and the bottom of the fixed end of the second hydraulic push rod 5 is assembled with a seat plate 6. By connecting and fixing one side of the seat plate 6 with the surface of the spray arm 4, the movable end of the second hydraulic push rod 5 passes through the inside of the seat plate 6, and the bottom of the control member 10 is fixedly connected to the outside of the nozzle 9 by screws. The movable end of the second hydraulic push rod 5 can be extended or retracted from the inside of the fixed end to control the distance between the heating seat 12 outside the nozzle 9 and the motor 3, thereby controlling the position of the heating seat 12 and the pipeline;

[0032] Furthermore, in order to prevent the nozzle 9 from rotating inside the spray arm 4 during the process of driving the heating seat 12 up and down, thereby affecting the orientation of the multiple liquid outlets 17 inside the spray arm 4, as shown in FIG. Figure 2 and Figure 3 As shown, a slide groove 7 is processed inside one end of the spray arm 4, and a slide seat 16 is processed outside one end of the nozzle 9. By supporting the bottom of the control member 10 and one end of the nozzle 9 on both sides of the spray arm 4 respectively, the slide seat 16 can be slidably connected to the inside of the slide groove 7 to guide the nozzle 9 to slide up and down.

[0033] By adopting the above technical solution:

[0034] The above design is that the heating seat 12 is set to be arc-shaped and sleeved on the outside of one end of the nozzle 9. When the first hydraulic push rod 1 pushes the support shaft frame 2 to drive the motor 3 and the spray arm 4 extends into the interior of the pipeline, the heating seat 12 is rotated outside the nozzle 9, so that the multiple injection ports 11 on the outer arc surface of the heating seat 12 are connected with the multiple liquid outlets 17 on the nozzle 9. The second hydraulic push rod 5 is used to pull the control member 10, so that the nozzle 9 is supported by the slide seat 16 and slides to one side of the motor 3, and then the motor 3 is used to control the spray arm 4 to drive the nozzle 9 and the heating seat 12 to perform the rotational spraying work on the inner wall of the pipeline;

[0035] When the heating seat 12 is located on the outside of the pipeline, the first hydraulic push rod 1 is controlled by means of the existing technology to drive the support shaft frame 2 to rotate, and the second hydraulic push rod 5 is used to push the control component 10, so that the nozzle 9 slides to the side away from the motor 3 under the support of the slide seat 16, and the motor 3 is stopped. The nozzle 9 and the heating seat 12 perform rotational spraying on the outer wall of the pipeline, which is convenient for spraying between the inner wall and the outer wall of the pipeline, with a small amount of paint loss and improved spraying efficiency by the rotational spraying method.

[0036] Embodiment 2:

[0037] Based on Example 1, this example introduces the specific structure of the spray arm 4. Figure 2 and Figure 3 As shown, the side of the spray arm 4 is assembled and connected with a buckle plate 8, one end of the heating seat 12 is processed with a gear 15, and the outer wall of one end of the heating seat 12 is processed with a receiving groove 14;

[0038] Among them, by hooking one side of the buckle plate 8 to one side of the gear 15 and being located inside the receiving groove 14, the heating seat 12 can be prevented from being separated from the outside of the nozzle 9;

[0039] Secondly, in order to make the nozzle 9 supported by the slide seat 16 to slide inside the slide groove 7, the directions of the inner and outer arc surfaces of the heating seat 12 can be automatically adjusted, such as Figure 2As shown, the inner wall of the buckle plate 8 is processed with a rack 13, so that the rack 13 is meshingly connected with the gear 15. When the nozzle 9 drives the heating seat 12 to move, the gear 15 at one end of the heating seat 12 can be controlled by the rack 13 on the buckle plate 8 fixed to the spray arm 4 to rotate.

[0040] By adopting the above technical solution:

[0041] The above design processes a gear 15 at one end of the heating seat 12 and assembles a buckle plate 8 with a rack 13 on the side of one end of the spray arm 4. When the second hydraulic push rod 5 drives the nozzle 9 to slide inside the slide groove 7 through the control member 10, one side of the buckle plate 8 can be hooked on one side of the gear 15 to prevent the heating seat 12 from being disconnected from the nozzle 9, and the gear 15 is engaged with the rack 13, so that the nozzle 9 drives the heating seat 12 to move, and the directions of the inner and outer arc surfaces of the heating seat 12 are automatically switched.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
