Description

Technical Field

[0001] The utility model relates to the technical field of steel structure surface spraying, and more specifically, to an assembled steel structure surface spraying device. Background Art

[0002] In recent years, with the rapid development of urban construction, more and more old urban areas have been demolished and renovated. Some public toilets in the old urban areas have been demolished. In order to ensure the normal needs of residents, environmentally friendly toilets will be set up in some places. Most environmentally friendly toilets are built with prefabricated steel structures as the main body. Since environmentally friendly toilets are placed outdoors and are easily affected by the external environment, it is necessary to spray the surface of the prefabricated steel structure.

[0003] After searching, the utility model patent with announcement number CN213996373U discloses an assembled steel structure anti-corrosion material mobile spraying device, which includes a base plate, casters, a box, a controller, a battery, a storage device, a high-pressure water pump, a material guide pipe, a spray gun, and a lifting mechanism; four casters are arranged under the base plate, and the box is arranged on the upper part of the base plate. The controller, battery, storage device, and high-pressure water pump are all arranged inside the box, and the connection relationship between the battery and the controller, high-pressure water pump, and lifting mechanism is an electrical connection; the high-pressure water pump is connected to the storage device through a pipeline, and the spray gun is connected to the high-pressure water pump through the material guide pipe; the lifting mechanism is arranged on the top of the box; it has a simple structure and is easy to operate. It can spray anti-corrosion materials on different types of steel structures. By setting a retractable material guide pipe, the operating range of the spray device is wider; and the spray gun can be fixed on the lifting mechanism, which can reduce the working intensity of the operator and save labor.

[0004] However, the above patent has the following shortcomings: when the spraying surface of the steel structure is large, the spray gun needs to be moved repeatedly to spray on the steel structure, which makes spraying the steel structure with only one spray gun inefficient. In addition, after the spray gun is installed on the spray gun mounting bracket, it is difficult to adjust the spraying distance between the spray gun and the steel structure. To address this problem, we propose an assembled steel structure surface spraying device. Utility Model Content

[0034] In this embodiment, the inner cavity of the feeding mechanism 20 is provided with anti-corrosion and anti-rust paint, which is sprayed onto the surface of the steel structure to achieve the function of anti-corrosion and anti-rust, while also making the steel structure have anti-corrosion, heat insulation, fire resistance and temperature resistance properties.

[0035] For details, please refer to Figures 1 to 3 The inner cavity of the outer box 1 is provided with a power supply battery 35, one end of the outer box 1 is fixedly connected to a push handle 39, one end of the outer box 1 is fixedly installed with a control panel 38, the other end of the outer box 1 is hinged with a box door 36, and the bottom surface of the outer box 1 is fixedly installed with multiple self-locking casters 37.

[0036] In this embodiment, the device is powered by a power supply battery 35 , controlled by a control panel 38 , moved by self-locking casters 37 , and pushed by a push handle 39 .

[0037] For details, please refer to Figure 1 The inner cavity of the vertical frame 2 is fixedly sleeved with two sliding rods 40, and the sliding rods 40 are movably sleeved with the lifting seat 5.

[0038] In this embodiment, the lifting seat 5 is limited by the sliding rod 40 so that the lifting seat 5 can only move along the axial direction of the screw rod 3.

[0039] Working principle: When it is necessary to spray the steel structure manually, start the first pump 16 to pump the paint in the inner cavity of the storage box 15 into the spray gun 9, and at the same time hold a handle 34 to pick up the spray gun 9, and use the paint sprayed by the spray gun 9 to spray the steel structure. When the spraying surface of the steel structure is large, start the second pump 18 to pump the paint in the inner cavity of the storage box 15 into the distribution pipe 12, and make the paint in the distribution pipe 12 be introduced into the spray head 14 through the switch valve 13. At the same time, hold another handle 34 to pick up the distribution pipe 12 and the spray head 14, and use multiple spray heads 14 to spray the surface of the steel structure. In addition, the spraying spray head 14 is controlled by opening and closing the switch valve 13, so as to change the spraying width, which is suitable for spraying steel structures of different widths.

[0040] When it is necessary to automatically spray the steel structure, the plug block 31 is inserted into the socket 27, and the elastic force of the spring 28 drives the pin 30 to be inserted into the socket 32 ​​to fix the plug block 31 and the socket 27, so that the spray gun 9 and the material distribution pipe 12 are installed on the two horizontal extension mechanisms 6, and the first motor 4 is used to drive the screw rod 3 to rotate, and the height of the spray gun 9 and the spray head 14 is adjusted by the threaded fit between the screw rod 3 and the lifting seat 5. In addition, the third motor 24 is used to drive the threaded rod 25 to rotate, and the screw rod 25 is used to rotate. The threaded fit between the threaded rod 25 and the telescopic column 26 drives the telescopic column 26 to extend and contract laterally, thereby changing the spraying position of the spray gun 9 and the spray head 14. In addition, the second motor 11 is used to drive the distribution pipe 12 and multiple spray heads 14 to rotate, changing the direction in which the multiple spray heads 14 spray the steel structure. During automatic spraying, the push handle 39 is held by hand to drive the device to move, so that the paint sprayed from the spray gun 9 or the spray head 14 is sprayed onto the steel structure, thereby having the effect of anti-corrosion, heat insulation, fire prevention and temperature resistance on the steel structure.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
