Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, and particularly relates to an automatic chimney anti-corrosion spraying device. Background Art

[0002] After searching the materials, it is found that a Chinese patent with the publication number CN214132372U in the prior art discloses an automatic chimney anti-corrosion spraying device, which includes a chimney body. The chimney body is a cylindrical structure with a hollow interior and openings at both the upper and lower ends. Two wire grooves with the same size are symmetrically opened on both inner side walls of the chimney body cavity. The wire grooves extend to the lower part of the inner cavity wall of the chimney body. A lifting mechanism is arranged at the upper end of the chimney body. Two support columns are symmetrically and fixedly installed on both outer surfaces of the chimney body. One end of each of the two support columns away from the chimney body is rotatably connected to a rotating column. A rotating handle is fixedly installed at one end of each of the two rotating columns away from the chimney body. A spraying mechanism is arranged in the inner cavity of the chimney body.

[0003] In the above solution, by slowly rotating the rotating handle, the rotation of the rotating column is driven, so as to wind and unwind the steel wire rope, enabling the spray gun to spray the inner cavity wall of the chimney body. And through the rotation of the rotating plate, the rotation of the spray gun is driven, realizing the rotary spraying of the inner cavity wall of the chimney body. The spraying effect is good, and it avoids the phenomenon that in the prior art, workers enter the chimney to apply anti-corrosion materials, which poses a threat to the safety of the human body. However, the above solution still has the following problems: It is necessary to fixedly install the support columns and the lifting mechanism on the chimney respectively, and at the same time, wire grooves need to be opened inside the chimney. This not only increases the installation steps before using the spraying device, increases the working intensity, and prolongs the working time, but also changing the original structure of the chimney by opening wire grooves on the inner wall of the chimney has low practicability and is not flexible and convenient to use.

Specific implementation mode

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] The present invention provides an automatic chimney anti-corrosion spraying device as Figures 1-4 shown, including a chimney body 100 and a spraying mechanism 200. Above the spraying mechanism 200, there is a hoisting mechanism 500. The structural composition and working principle of the spraying mechanism 200 can be referred to the spraying mechanism in the patent with the publication number CN214132372U and the name of an automatic chimney anti-corrosion spraying device. In this application, it can be installed upside down to be more suitable for the use of this application. The hoisting mechanism 500 is provided with a positioning mechanism for positioning the hoisting mechanism 500 at the top port of the chimney body 100. The hoisting mechanism 500 is installed on the positioning mechanism. Through the hoisting mechanism 500, the height of the spraying mechanism 200 in the chimney body 100 can be adjusted, so that the spraying mechanism 200 can spray the inner wall of the chimney body 100 everywhere, improving the spraying quality. The positioning mechanism includes:

[0022] A bearing plate 400 is arranged above the chimney body 100 for bearing the hoisting mechanism 500;

[0023] At least two support plates 401 are symmetrically arranged on the side wall of the bearing plate 400 for supporting the bearing plate 400 on the chimney body 100. Among them, the support plates 401 are preferably 3 or 4, and are equally spaced on the side wall of the bearing plate 400. To increase the stability of the support plates 401 placed on the chimney body 100, an anti-slip gasket or a frosted layer can be added to its lower surface, and at the same time, a block perpendicular to its lower surface (not shown in the figure) can be added to increase the stability of the support plates 401 placed on the chimney body 100.

[0024] The above solution can support the bearing plate 400 on the chimney body 100 through the support plate 401, so that the bearing plate 400 and the hoisting mechanism 500 thereon can be conveniently and quickly positioned and installed on the chimney body 100, simplifying the preliminary installation steps of the spraying device, reducing the working intensity, and improving the operation convenience and working efficiency.

[0025] In a preferred embodiment, a receiving groove 404 is formed at one end of the support plate 401 facing the chimney body 100. An auxiliary support rod 405 is movably inserted into the receiving groove 404. One end of the auxiliary support rod 405 is fixedly connected to the side wall of the chimney body 100. A locking mechanism is fixedly arranged at the end of the outer wall of the support plate 401 for locking the position between the support plate 401 and the auxiliary support rod 405. The receiving groove 404 can be used to enable the support plate 401 to translate on the outer wall of the auxiliary support rod 405 and adjust its extended length, which can meet the use of chimney bodies 100 with various diameters and increase the adaptability of use.

[0026] Furthermore, the locking mechanism includes a locking bolt 406. The locking bolt 406 is threadedly connected to an internal thread hole formed at the end of the outer wall of the support plate 401. The bottom end of the locking bolt 406 penetrates through the internal thread hole and extends into the receiving groove 404. By tightening or loosening the locking bolt 406, the fixing or unlocking between the support plate 401 and the auxiliary support rod 405 can be carried out, which is convenient for adjustment.

[0027] At the same time, the hoisting mechanism 500 includes two fixing plates 501 symmetrically and fixedly connected to the top end of the bearing plate 400. A rotating shaft 502 is rotatably connected between the two fixing plates 501. A winding roller 503 is fixedly sleeved on the outer wall of the rotating shaft 502. A steel wire rope is wound around the outer wall of the winding roller 503. A winding motor 504 is fixedly connected to the outer wall of the fixing plate 501 for driving the rotation of the rotating shaft 502. By driving the rotating shaft 502 to rotate clockwise or counterclockwise by the winding motor 504, the winding roller 503 can be driven to rotate, and the steel wire rope can be wound or unwound, so as to realize the adjustment of the height of the spraying mechanism 200 in the chimney body 100.

[0028] Furthermore, a detachable connecting seat 300 is fixedly provided at the bottom end of the steel wire rope. The spraying mechanism 200 is fixedly installed at the bottom end of the connecting seat 300. The spraying mechanism 200 can perform spraying operations at the bottom end of the connecting seat 300. A wire passing through hole 407 is formed at the top end of the bearing plate 400. The wire passing through hole 407 is located directly below the winding roller 503. An auxiliary fixed pulley 402 is provided at one side of the wire passing through hole 407 at the top end of the bearing plate 400. Both ends of the auxiliary fixed pulley 402 are rotatably connected to a fixed seat 403. The bottom end of the fixed seat 403 is fixedly connected to the top end of the bearing plate 400. The cooperation of the wire passing through hole 407 with the fixed seat 403 and the auxiliary fixed pulley 402 can guide the vertical movement direction of the steel wire rope, and increase the stability during the winding or unwinding process of the steel wire rope.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
