Description

Technical Field

[0001] The present invention relates to the technical field related to coating, and in particular to an anti-corrosion coating device for the inner wall of a pipeline. Background Art

[0002] When processing pipelines, it is usually necessary to spray paint on the inner wall of the pipeline to prevent rust and corrosion. At this time, a tubular inner wall paint brushing device is needed.

[0003] At present, the anti-corrosion painting device for the inner wall of pipelines on the market generally sprays paint on the inner wall of the pipeline through a sprayer, and moves the sprayer inside the pipeline by manpower, thereby realizing anti-corrosion painting on the inside of a long length of pipeline. However, in actual use, its scope of application is relatively small, and it can only perform anti-corrosion painting operations on pipelines of specified sizes. In related technologies, a knob is set to drive the sliding part to rotate and move it linearly along the screw rod, driving another sliding part to move, and finally extending the cross rod so that the roller can contact the inner wall of the pipeline, which is convenient for subsequent painting work. Although it can be applied to a variety of pipelines, its adjustment range is relatively small, and in actual use, the paint will contact the screw rod, reducing the service life of the screw rod, and during adjustment, it will cause movement to be obstructed, affecting normal adjustment, and has certain limitations.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0046] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0047] In view of the current existing technology, a knob is set to drive the sliding part to rotate and move it linearly along the screw, driving another sliding part to move, and finally extending the cross rod so that the roller can contact the inner wall of the pipe, which is convenient for subsequent painting work. Although it can be applied to a variety of pipes, its adjustment range is small, and in actual use, the paint will contact the screw, reducing the service life of the screw, and during adjustment, it will cause movement to be obstructed, affecting normal adjustment, and has certain limitations.

[0048] like Figure 1-3 As shown, an embodiment of the present invention provides an anti-corrosion painting device for the inner wall of a pipeline, comprising: a mounting rod 10, the inner side of which is rotatably connected to a feed pipe 11; a nozzle 12, arranged at one end of the feed pipe 11; a telescopic rod 20, fixedly connected to the outside of the mounting rod 10; a shell 21, fixedly connected to the outer end of the telescopic rod 20; a wheel 22, rotatably connected to the inside of the shell 21; a ring body 23, fixedly connected to the outside of the mounting rod 10; a ring body 24, threadedly connected to the inside of the ring body 23; a round head rod 25, slidably connected to the ring body 23; two springs 26, one of which is sleeved on the outside of the round head rod 25, and the round head rod 25 is connected to the ring body 23 through the spring 26, and the other is arranged in the telescopic rod 20; a socket 27, opened on the telescopic rod 20, and one end of the round head rod 25 is inserted into the socket 27.

[0049] After connecting the feeding pipe 11 with the anti-corrosion paint delivery pipe, the mounting rod 10 is placed on the inner side of the pipe to be processed, and the spring 26 in the telescopic rod 20 pushes the telescopic rod 20 to extend, and after the wheel 22 is pressed against the inner side of the pipe, the ring body 24 is rotated to move the ring body 24 in the ring body 1 23, and the multiple round-headed rods 25 are squeezed so that the round-headed rods 25 are inserted into the jacks 27 on the outside of the telescopic rod 20. After limiting the telescopic length of the telescopic rod 20, the adjustment is completed. At this time, when applying the anti-corrosion paint, the staff pulls and rotates the feeding pipe 11 to drive the mounting rod 10 to move in the pipe, and the multiple wheels 22 rotate accordingly, thereby ensuring that the mounting rod 10 and the feeding pipe 11 are located in the center of the pipe, and at the same time, the nozzle 12 is rotated and moved to apply the anti-corrosion paint on the inner wall of the pipe.

[0050] Furthermore, a plurality of wheels 22 are provided in each of the housings 21 , so that the movement of the mounting rod 10 is more stable.

[0051] Furthermore, a push block 241 is fixedly connected to the outer side of the second ring body 24 , and the second ring body 24 is rotated by pushing the push block 241 , which facilitates operation.

[0052] Furthermore, the telescopic rod 20, the housing 21, the wheel 22, the round head rod 25, the spring 26 and the socket 27 form a group, and multiple groups are provided on the outside of the mounting rod 10.

[0053] The plurality of wheels 22 are brought into contact with the inner wall of the pipe at the same time, thereby achieving a better positioning effect.

[0054] Furthermore, the ring body three 30 is rotatably connected to the outside of the mounting rod 10; the telescopic rod two 31 is fixedly connected to the outside of the ring body three 30; the scraper 32 is fixedly connected to the outer end of the telescopic rod two 31; the fastening bolt 33 is threadedly connected to the telescopic rod two 31, and the ring body three 30 is transmission-connected to the wheel 22 through the transmission mechanism 40.

[0055] While the mounting rod 10 moves on the inner wall of the pipe, the wheel 22 drives the ring body three 30 to rotate through the transmission mechanism 40, so that the ring body three 30 drives the scraper 32 to rotate through the telescopic rod two 31, so as to spread the thicker paint, thereby making the anti-corrosion paint more evenly applied. Moreover, by changing the height of the telescopic rod two 31 and rotating the fixing bolt 33, the height of the scraper 32 can be adjusted, thereby adjusting the paving thickness and increasing the scope of application.

[0056] Furthermore, the transmission mechanism 40 includes: a steering gear 404, fixedly connected to the shell 21; a rod body 401, arranged on the wheel 22 and the steering gear 404; a transmission wheel 402, fixedly connected to one end of the rod body 401, and the two transmission wheels 402 are connected by a transmission belt 403; a steering gear 2 405, fixedly connected to the outside of the mounting rod 10; a connecting rod 406, arranged on the steering gear 2 405, and the steering gear 1 404 and the steering gear 2 405 are connected by the connecting rod 406; a gear set 407, arranged between the steering gear 2 405 and the ring body 3 30.

[0057] When the wheel 22 rotates, it drives a rod body 401 and a transmission wheel 402 to rotate, and then through the transmission of the transmission belt 403, the other transmission wheel 402 drives the other rod body 401 to rotate, and then through the action of the steering gear 1 404, the connecting rod 406 rotates, and then through the action of the steering gear 2 405 and the gear set 407 in sequence, the ring body 30 rotates, thereby achieving the rotation of the scraper 32 around the central axis of the ring body 30 while moving, which is convenient for spreading paint.

[0058] Furthermore, the steering gear 404 is composed of a box body and bevel gears, so that the rod body 401 drives the connecting rod 406 to rotate through the bevel gear transmission, and the connecting rod 406 drives the gear set 407 to work through the bevel gear transmission.

[0059] Furthermore, the gear set 407 is composed of two gears that mesh with each other, one gear is set on the diverter 2 405, and the other gear set 407 is fixedly connected to the outside of the ring body 30. When the connecting rod 406 drives one gear to rotate through the diverter 2 405, the other gear meshes with the other gear, causing the other gear to drive the ring body 30 to rotate.

[0060] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
