Description

Technical Field

[0001] The utility model relates to the technical field of steel structure spraying fireproof coatings, in particular to a guiding device for steel structure fireproof spraying. Background Technique

[0002] After the steel structure is completed, a layer of fireproof coating needs to be sprayed on its surface. Thus, in case of fire, relying on the incombustibility and low thermal conductivity of the coating itself, a refractory heat insulation protective layer is formed to slow down the direct attack of the fire on the load-bearing members;

[0003] However, due to the various shapes of steel structures, it is necessary to adjust the angle, height, etc. of the nozzle through a guiding device during spraying. However, the existing guiding devices do not have a protection structure, resulting in the sprayed fireproof coating being easily attached to the adjusting components, which is likely to affect the use of the adjusting components after curing. Content of the Utility Model

[0004] The purpose of the utility model is to provide a guiding device for steel structure fireproof spraying, so as to solve the problem that the existing guiding devices do not have a protection structure, resulting in the sprayed fireproof coating being easily attached to the adjusting components, which is likely to affect the use of the adjusting components after curing as proposed in the above background technique.

Specific implementation mode

[0019] 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.

[0020] Please refer to Figures 1-3 , the present invention provides a technical solution:

[0021] In this technical solution, a guiding device for fire spraying of steel structures includes a vehicle body 1 and an adjusting component 2. An adjusting component 2 and a spraying device 3 are installed on the upper wall of the vehicle body 1, and the output end of the spraying device 3 is installed above the adjusting component 2;

[0022] The adjusting component 2 includes an electric control push rod 21, a protective cover 22, a motor 23 and a rotating sleeve 24. An electric control push rod 21 is installed on the upper wall of the vehicle body 1, a protective cover 22 is installed at the output end of the electric control push rod 21, a motor 23 is installed inside the protective cover 22, both the electric control push rod 21 and the motor 23 are electrically connected to an external power source, a rotating sleeve 24 is installed at the output end of the motor 23, the rotating sleeve 24 is sleeved outside the protective cover 22, one end of a support rod 4 is installed on the upper wall of the rotating sleeve 24, and the output end of the spraying device 3 is installed at the other end of the support rod 4;

[0023] In this technical solution, the adjusting component 2 can drive the output end of the spraying device 3 to lift or rotate, so as to achieve the purpose of guiding the spraying direction of the output end of the spraying device 3, so that it can spray all different surfaces of the steel structure and avoid missed spraying;

[0024] For example, for an I-shaped steel, if it is directly sprayed, the inner two walls cannot be sprayed in place, so it is necessary to adjust and guide the spraying angle through the adjusting component 2;

[0025] The device also sets a protective cover 22 and a rotating sleeve 24 in its adjusting component 2. The rotating sleeve 24 will cover the protective cover 2, so that the paint splashed during spraying will fall outside the rotating sleeve 24 and will not fall on the protective cover 22, thus avoiding the situation that the rotation of the rotating sleeve 24 is affected after the paint solidifies.

[0026] In some technical solutions, a fixing ring 5 is installed on the upper wall of the electric control push rod 21. The fixing ring 5 is sleeved outside the output end of the electric control push rod 21. A heating cavity 6 is provided in the fixing ring 5, and an electric heating wire 7 is installed in the heating cavity 6. The electric heating wire 7 is electrically connected to an external power supply. An annular scraper 8 is installed on the upper wall of the fixing ring 5, and the annular scraper 8 is attached to the side wall of the output end of the electric control push rod 21.

[0027] In this technical solution, in order to avoid the influence on the retraction of the electric control push rod 21 after the paint solidifies, the device sets a fixing ring 5 above its electric control push rod 21. The paint attached to the outside of the output end of the electric control push rod 21 can be softened through the fixing ring 5, and then during the retraction of the electric control push rod 21, the paint is scraped off by the annular scraper 8 to avoid the situation that the electric control push rod 21 cannot contract due to the paint;

[0028] After the electric heating wire 7 in the fixing ring 5 is heated, the heat will be conducted to the output end of the electric control push rod 21 through the fixing ring 5, thereby softening the paint on the outer wall of the output end of the electric control push rod 21.

[0029] In some technical solutions, the spraying device 3 includes a storage tank 31, an air tank 32, a pump 33, a spray head 34, an air pipe 35 and a feed pipe 36. The storage tank 31 and the air tank 32 are both installed on the upper wall of the vehicle body 1. A pump 33 is installed on the side wall of the storage tank 31. The pump 33 is electrically connected to an external power supply. The input end of the pump 33 is inserted into the inner cavity of the storage tank 31. One end of a feed pipe 36 is installed at the output end of the pump 33. The other end of the feed pipe 36 is installed with a spray head 34. The spray head 34 is fixed on the support rod 4. One end of an air pipe 35 is inserted and installed on the upper wall of the spray head 34, and the other end of the air pipe 35 is communicated with the air tank 32.

[0030] In this technical solution, the pump 33 pumps the fireproof paint in the storage tank 31 into the spray head 34. At the same time, the compressed air in the air tank 32 will also enter the spray head 34 through the air pipe 35. Under the action of the compressed air, the paint in the spray head 34 is sprayed out and attached to the outer surface of the steel structure. After curing, a fireproof and heat-insulating layer is formed to achieve the protection of the steel structure.

[0031] In some technical solutions, a stirring motor 10 is installed on the upper wall of the storage tank 31. The stirring motor 10 is electrically connected to an external power supply. The output end of the stirring motor 10 penetrates the upper wall of the storage tank 31 and is installed with a stirring frame 11;

[0032] In this technical solution, since the fireproof coating is relatively viscous and the time required for its curing is short, in order to prevent the fireproof coating from solidifying in the storage tank 31, a stirring motor 10 is provided above the storage tank 31 of this device. The stirring motor 10 drives the stirring frame 11 to rotate, so as to prevent the fireproof coating in the storage tank 31 from solidifying and affecting the use.

[0033] In some technical solutions, universal wheels 12 are installed at the four corners of the lower wall of the vehicle body 1.

[0034] In this technical solution, by setting the universal wheels 12, the vehicle body 1 can be conveniently moved.

[0035] Working principle: When using this device, the staff first move the vehicle body 1 to the steel structure to be sprayed. Then, according to the height of the steel structure, the electric control push rod 21 is controlled to extend, so that its spraying head 34 reaches one side of the steel structure. Then, the spraying device 3 is started, and the fireproof coating is sprayed out through the spraying head 34. During the spraying process, the staff can control the rotation of the motor 23 through an external controller to adjust the angle of the spraying head 34, so that different surfaces of the steel structure can be fully sprayed, avoiding missed spraying.
