Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to a spraying device for the surface of steel structure columns. Background Technology

[0002] Steel structural columns are vertical support components made of steel. Their main function is to bear the weight of the building's superstructure and safely transfer the load to the foundation. Their design must meet the requirements of strength, stability, and durability. After the steel structural columns are manufactured, a rust-proof layer is sprayed on their surface to prevent damage.

[0003] Currently, the surface spraying of steel structure columns is mostly carried out manually using handheld spraying equipment. However, due to the difficulty in accurately controlling the moving speed and spray gun angle during manual spraying, problems such as uneven coating thickness, missed spraying, or paint film accumulation are prone to occur. At the same time, paint mist can easily diffuse into the air during the spraying process, which not only wastes paint but also exposes operators to a polluted environment containing volatile organic compounds for a long time, posing occupational health and safety hazards. Therefore, a steel structure column surface spraying device is proposed to solve the above-mentioned problems. Utility Model Content

It solves the problem that currently, the surface spraying operation of steel structure columns is mostly carried out by manual hand-held spraying equipment. Due to the difficulty in accurately controlling the moving speed and spray gun angle of manual spraying, problems such as uneven coating thickness, missed spraying, or paint film accumulation are easily caused. At the same time, paint mist is easily diffused into the air during the spraying process, which not only wastes paint, but also exposes operators to a polluted environment containing volatile organic compounds for a long time, posing occupational health and safety hazards.

[0009] The beneficial effects of this utility model are:

[0010] This steel structure column surface spraying device has the advantages of making the paint spraying on the surface of the steel structure column more uniform, and at the same time effectively preventing paint leakage during the spraying process.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the embodiments, by Figure 1-5 The present invention provides a steel structure column surface spraying device, which includes a support base 1, a support plate 2 fixed to the top of the support base 1, an atomizing box 3 disposed on the outside of the support plate 2, and an atomizing nozzle 10 communicating with the atomizing box 3. The support base 1 has a transmission cavity 4 inside, and a rotating column 5 that can rotate around a vertical axis is disposed in the transmission cavity 4. The top end of the rotating column 5 extends above the support base 1 and is fixedly connected to a base plate 6 that supports the steel structure body 9. A blocking component 11 is disposed on the outside of the steel structure body 9.

[0029] The rotating column 5 is provided with a self-locking transmission mechanism 7 for rotating it, and the base plate 6 is provided with a detachable base 8. The steel structure body 9 is embedded in the inside of the detachable base 8.

[0030] The blocking assembly 11 includes a groove 111 opened on the top of the support base 1, two sliders 112 slidably disposed in the groove 111, a connecting plate 113 fixedly connected to the sliders 112, and a blocking shell 114 fixedly connected to the top of the connecting plate 113. The blocking shell 114 and the support plate 2 form a spraying cavity, and the steel structure body 9 is located in the spraying cavity.

[0031] The inner side of the blocking shell 114 is provided with absorbent cotton, which can absorb the sprayed paint, so that excess paint can be blocked during the spraying of the steel structure body 9 surface.

[0032] Meanwhile, the slide 111 and the slider 112 allow the blocking shell 114 to move left and right, which facilitates the disassembly of the blocking shell 114 and thus facilitates the installation of the steel structure body 9.

[0033] The atomizing nozzles 10 are multiple, and the multiple atomizing nozzles 10 are distributed in a straight line array at equal intervals on the outside of the atomizing box 3. The top of the atomizing box 3 is provided with a feed pipe 12 for replenishing the spraying material.

[0034] The presence of multiple atomizing nozzles 10 allows for more uniform coating of the steel structure body 9. The feed pipe 12 can guide the paint into the atomizing box 3, which is then sprayed out through the atomizing nozzles 10.

[0035] The support base 1 has an annular limiting groove 13 at its top, and the bottom of the base plate 6 is fixedly connected with at least three circumferentially distributed limiting rods 14, which slide in cooperation with the annular limiting groove 13.

[0036] The annular limiting groove 13, together with the limiting rod 14, can prevent the base plate 6 from shifting position during rotation, thus improving the stability of the base plate 6 during rotation.

[0037] The self-locking transmission mechanism 7 includes a power motor 71, a power worm gear 72, and a power worm 73. The power motor 71 is fixedly installed on the outside of the support base 1, and its output shaft is fixedly connected to the power worm 73 via a coupling. The power worm gear 72 is fixedly installed on the outside of the rotating column 5, and the outside of the power worm gear 72 meshes with the outside of the power worm 73.

[0038] Starting the power motor 71 causes the power worm gear 73 to rotate, which in turn drives the rotating column 5 to rotate via the power worm wheel 72, thereby making the surface of the steel structure body 9 more evenly coated.

[0039] The detachable base 8 includes a mounting base plate 81 that is bolted to the base plate 6 and a positioning frame 82 that is vertically fixed on the mounting base plate 81. The inner contour of the positioning frame 82 is adapted to the cross-sectional shape of the steel structure body 9.

[0040] The positioning frame 82 facilitates the installation operation on the outside of the steel structure body 9.

[0041] Working principle:

[0042] When it is necessary to spray the steel structure body 9, place the steel structure body 9 inside the positioning frame 82, then insert the slider 112 into the inside of the slide groove 111, and then move the blocking shell 114 to the outside of the steel structure body 9.

[0043] Then, the feed pipe 12 feeds the coating material, which is then sprayed out through the atomizing nozzle 10 on the outside of the atomizing box 3, thereby spraying the surface of the steel structure body 9. At the same time, the power motor 71 is started, causing the power worm gear 73 to rotate, which in turn drives the rotating column 5 to rotate through the power worm wheel 72, thus rotating the steel structure body 9 and making the surface of the steel structure body 9 more evenly coated. During the spraying process, excess coating material is blocked by the blocking shell 114, effectively preventing coating leakage.
