Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] See also Figure 1-4 A thermal spraying device for anti-corrosion coating on the inner wall of a pipeline in this embodiment includes a mounting frame 1, and a processing mechanism is provided on the upper surface of the mounting frame 1. The processing mechanism includes a spray box 2 fixedly mounted on the upper surface of the mounting frame 1, a storage box 3 fixedly mounted on the upper surface of the mounting frame 1, a clamping mechanism 4 arranged in the spray box 2 and an auxiliary mechanism 5 arranged in the storage box 3. The clamping mechanism 4 includes a clamping box 41 fixedly mounted in the spray box 2, a first cylinder 42 fixedly mounted in the clamping box 41, a rack 43 fixedly mounted at the output end of the first cylinder 42, a gear 44 rotatably mounted in the clamping box 41, a first rotating rod 45 fixedly mounted on the outer peripheral wall of the gear 44, a connecting rod 46 fixedly mounted on the outer peripheral wall of the first rotating rod 45 and a clamping plate 47 fixedly mounted on the outer peripheral wall of the connecting rod 46.

[0026] In this embodiment, the auxiliary mechanism 5 includes a second cylinder 51 fixedly installed in the storage box 3, an extrusion plate 52 fixedly installed at the output end of the second cylinder 51, a heating plate 53 fixedly installed in the storage box 3 and a heating wire 54 fixedly installed in the heating plate 53.

[0027] In this embodiment, a spray pipe 6 which is inserted into the spray box 2 is fixedly connected to the left surface of the storage box 3, and a solenoid valve 7 is fixedly connected to the outer wall of the spray pipe 6. By setting the solenoid valve 7, spraying can be performed.

[0028] In this embodiment, a spray head is fixedly connected to the left surface of the spray pipe 6, and an observation window is provided on the front surface of the storage box 3, so that the user can observe the anti-corrosion material in the storage box 3 and add materials.

[0029] In this embodiment, there are two clamping boxes 41 , and the upper surface of the spray box 2 is an opening. By setting the upper surface of the spray box 2 as an opening, it is convenient to put the pipeline into the spray box 2 .

[0030] In this embodiment, the outer peripheral wall of the clamping plate 47 is coated with a rubber layer, and a feed pipe is fixedly connected to the front surface of the storage box 3. By providing the rubber layer, the clamping plate 47 is prevented from clamping the pipe.

[0031] It should be noted that the rack 43 and the gear 44 are meshed with each other, and the spray tube 6 is a hose. By setting the spray tube 6 as a hose, it is convenient for the user to hold the spray tube 6 to move it for spraying.

[0032] Embodiment 2:

[0033] See also Figure 1-4 On the basis of the first embodiment, an end cover is hinged on the outer wall of the feed pipe, and a maintenance window is hinged on the outer wall of the clamping box 41. The maintenance window is provided to facilitate maintenance.

[0034] The working principle of the above embodiment is:

[0035] The user first puts the pipe into the spray box 2, and then starts the first cylinder 42. The first cylinder 42 drives the rack 43 to slide, the rack 43 drives the gear 44 to rotate, the gear 44 drives the first rotating rod 45 to rotate, the first rotating rod 45 drives the connecting rod 46 and the clamping plate 47 to slide to clamp the pipe, and then the user starts the second cylinder 51. The second cylinder 51 drives the extrusion plate 52 to squeeze downward, and the extrusion plate 52 squeezes the anti-corrosion material downward. Then the user starts the solenoid valve 7 to let the spray pipe 6 spray the material to the pipe through the nozzle, thereby completing the entire operation process.

[0036] The above beneficial effects are:

[0037] The first cylinder is started to move the rack to drive the gear to rotate, and the gear drives the first rotating rod to rotate. When the first rotating rod rotates, it drives the connecting rod and the clamping plate to move. The two clamping plates clamp the pipeline, thereby solving the problem of not being able to clamp pipelines of different diameters. The second cylinder is started to drive the extrusion plate to move, thereby preventing the anti-corrosion material from being sticky and difficult to move. By setting a heating plate, the anti-corrosion material can be heated, thereby increasing the spraying effect.

[0038] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
