Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, and in particular to a steel structure protective coating spraying mechanism. Background Technology

[0002] Steel structures are widely used in buildings, bridges, large stadiums, and other facilities due to their high strength, light weight, and fast construction speed. However, steel structures are exposed to the natural environment for extended periods and are susceptible to corrosion from atmospheric moisture, oxygen, and corrosive media. Therefore, it is essential to apply an anti-corrosion coating to their surface to extend their service life.

[0003] Currently, the application of protective coatings to steel structures mainly relies on manual spraying. This involves repeatedly spraying the surface of the steel structure with a handheld spray gun. However, since steel structural components (such as beams and columns) are usually large in size and length, manual spraying is not only labor-intensive and time-consuming, but also makes it difficult to ensure the uniformity of the coating thickness, thus affecting the reliability of the anti-corrosion effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel structure protective coating spraying mechanism, which solves the problems of low efficiency and quality in manually spraying anti-corrosion layers on steel structures.

[0009] The first adjusting member is located on the support base. The mounting base has a sliding groove with the mounting shaft of the support base as the axis. The first adjusting member is slidably located in the sliding groove to limit the position of the support base in the sliding groove.

[0010] The second adjusting component is located on the mounting bracket and connected to the two mounting seats, and is used to adjust the distance between the two mounting seats.

[0011] Preferably, the first adjusting member includes:

[0012] The stud is fixedly mounted on the side of the support base and slidably mounted in the groove.

[0013] A threaded ring is threaded onto a stud, and the end face of the threaded ring abuts against the side of the mounting base.

[0016] Preferably, the spray head includes a spray pipe disposed on the spray tube, a corrugated pipe disposed at the end of the spray pipe, and a nozzle disposed at the end of the corrugated pipe.

[0017] Preferably, the nozzle is equipped with a valve.

[0018] Preferably, the end of the spray pipe is provided with a connecting pipe.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0035] This utility model embodiment proposes a steel structure protective coating spraying mechanism, installed on the steel structure body 1, including:

[0036] Mounting frame 2, mounting frame 2 is equipped with spray pipe 4, spray pipe 4 is provided with a number of spray nozzles 401 at intervals;

[0037] Mounting base 5, two mounting bases 5 are slidably disposed at both ends of mounting frame 2, and both mounting bases 5 are rotatably provided with support base 6, support base 6 is provided with roller 601, and roller 601 has limiting groove 602;

[0038] The first adjusting member is provided on the support base 6. The mounting base 5 has a sliding groove 501 with the mounting shaft of the support base 6 as the axis. The first adjusting member is slidably provided on the sliding groove 501 to limit the position of the support base 6 in the sliding groove 501.

[0039] The second adjusting member is located on the mounting bracket 2 and connected to the two mounting seats 5, and is used to adjust the distance between the two mounting seats 5.

[0040] In the embodiments of this utility model, the spraying mechanism is mainly applied to H-beams or I-beams, such as... Figure 1As shown, each nozzle 401 is installed on the straight section of the spray pipe 4, and the nozzles 401 are spaced apart. In the spaced dimensions, according to the spray range of the nozzle 401, in conventional fields, the spray cross section of the nozzle 401 is generally fan-shaped. When selecting the installation position of the nozzle 401, the optimal spray surface is when the fan-shaped cross sections of two adjacent nozzles 401 intersect, so that the fan-shaped cross sections sprayed by each nozzle 401 just form the surface to be sprayed on the steel structure. When the mounting frame 2 moves on the steel structure with the cooperation of the support seat 6 and the roller 601, the entire surface to be sprayed on the steel structure can be completed quickly and evenly. Compared with manual operation, it can further ensure the quality of spraying, avoid defects such as uneven thickness, sagging, and missed coating caused by manual operation, and improve the construction quality of anti-corrosion coating.

[0041] Secondly, the support base 6 can rotate on the mounting base 5, such as... Figure 2 and Figure 5 As shown, in the initial state, one flange of the I-beam can be sprayed first. Under the action of the first adjusting component, the initial state of roller 601 is... Figure 5 As shown, the limiting grooves 602 of the two rollers 601 can be respectively engaged on both sides of the flange to limit the mounting frame 2, so that the mounting frame 2 can move along the axis of the steel structure. After the spray pipe 4 is connected to the external delivery source, the mounting frame 2 can be moved so that it can be uniformly sprayed along the axis of the steel structure under the action of the rollers 601.

[0042] When spraying paint on the side (web area) of the steel structure, the steel structure can be flipped over, and the angle of the support 6 can be adjusted by the first adjusting component, causing the roller 601 to flip over. The flipped shape is as follows. Figure 3 As shown, two rollers 601 can be mounted between the two flanges of the steel structure, and the web area of ​​the steel structure can be sprayed evenly and stably under the movement of the mounting frame 2.

[0043] Furthermore, under the action of the second adjusting member, the distance between the two rollers 601 can be adjusted, and with the cooperation of the first adjusting member, the two rollers 601 can be mounted on a flange of different widths, or the two rollers 601 can be mounted between two flanges with different distances.

[0044] When moving the mounting bracket 2, it can be driven automatically, for example, by providing a motor power source to the roller 601 motor to achieve automated movement, or it can be driven manually by directly pushing the mounting bracket 2. The specific driving method can be selected according to the actual use situation.

[0045] Specifically, the structure of the first adjusting component is optimized, such as... Figure 5 As shown, the first adjusting member includes:

[0046] The stud 503 is fixedly disposed on the side of the support base 6 and slidably disposed in the slide groove 501.

[0047] Threaded ring 502 is threadedly connected to stud 503, and the end face of threaded ring 502 abuts against the side of mounting base 5.

[0048] When adjusting the angle of the support seat 6 using the first adjusting member, the angle of the support seat 6 can be adjusted at two angles: 0° and 90°, to satisfy the vertical and lateral positioning and sliding of the roller 601. When the limit on the support seat 6 is released, simply loosen the threaded ring 502 to move it away from the side of the mounting seat 5 on the stud 503. After the limit on the support seat 6 is released, simply flip the support seat 6 so that the stud 503 can move in the slide groove 501. When the threaded ring 502 is tightened, the end face of the mounting seat 5 can be tightly pressed against the side of the mounting seat 5, and the resulting friction can lock the position of the support seat 6, quickly completing the angle adjustment and limit of the support seat 6.

[0049] Specifically, the structure of the second adjusting component is optimized, such as... Figure 1 and Figure 2 As shown, the second adjusting component includes an adjusting rod 3, which is rotatably mounted on the mounting bracket 2. Both ends of the adjusting rod 3 are provided with threaded sections 301 with opposite threads, and the two threaded sections 301 are respectively threadedly connected to the two mounting seats 5.

[0050] When the adjusting rod 3 is rotated, the two mounting seats 5 will move synchronously, towards each other or away from each other, using the principle of reverse thread, thereby expanding or shrinking the distance between the two rollers 601, making it convenient to install the rollers 601 onto the flange of the steel structure, with a very wide range of applicability.

[0051] Meanwhile, an adjusting block 302 is fixedly provided at the end of the adjusting rod 3. The adjusting block 302 can be in the form of a nut, and the adjusting rod 3 can be adjusted by tools, saving manpower. Furthermore, the cross-section of the mounting bracket 2 is rectangular, which can limit the mounting seat 5 to avoid the overturning force when the adjusting rod 3 is rotated, thus preventing it from bending.

[0052] like Figure 4As shown, the spray head 401 includes a spray pipe 402 disposed on the spray pipe 4, a corrugated pipe 404 disposed at the end of the spray pipe 402, and a nozzle 405 disposed at the end of the corrugated pipe 404. The corrugated pipe 404 is made of rigid material and can be fixed in shape by bending. For example, a metal corrugated pipe can be bent left, right, up, and down, so that the spraying position and range of the nozzle 405 can be adjusted in a controllable manner. For example, when spraying the web, the corrugated pipes 404 at both ends can be bent so that the nozzles 405 connected to them point to the inner side of the flange, so as to achieve full spraying.

[0053] Secondly, the spray nozzle 402 is equipped with a valve 403. When spraying steel structures with flanges and webs of different widths, the valve 403 of the spray nozzle 402 can be used to close the passage of the nozzle that does not correspond to the steel structure when the bellows 404 of the bent section of the spray nozzle 402 is used to meet the full spraying needs, thus avoiding material waste. Furthermore, the end of the spray pipe 4 is equipped with a connecting pipe 406, facilitating the connection of external pipelines to the spray pipe 4 to complete the delivery of the protective coating. After construction is completed, the overall structure is small and lightweight, making it easy to clean.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
