Description

Technical Field

[0001] This utility model relates to the technical field of painting devices, and in particular to a painting device for steel structures. Background Technology

[0002] Steel structures mainly include steel frame structures, steel truss structures, space frame and shell structures, portal frame structures, suspension and tension structures, and composite structures, and are widely used in buildings, bridges, stadiums and other fields.

[0003] In the prior art, Chinese patent CN220969641U discloses a steel structure painting device. This device consists of a heating box, electric heating wire, air pump, and air vent. The steel structure is placed between a first and second clamping plate on a fixing mechanism. A pneumatic telescopic rod pushes a sliding block, clamping and fixing the steel structure through the first and second clamping plates. An electric push rod then moves a movable seat, allowing the spray nozzle to spray paint the steel structure surface. After the painting process, the electric heating wire in the heating box generates heat. However, in practical applications, steel structures require painting before use. Most steel structure painting is done by spraying. Existing spraying devices mostly use a spray nozzle to vertically spray the steel structure. When using such spraying devices, H-shaped steel used in steel structures is prone to insufficient coating thickness, resulting in substandard quality after painting and requiring rework. This leads to low painting efficiency for H-shaped steel. Therefore, we disclose a steel structure painting device. Utility Model Content

[0013] The beneficial effects of this utility model are as follows: When in use, the steel body can move within the paint box, and the position of the conveying pipe is fixed by the paint box, so that the conveying pipe can simultaneously deliver paint to the first paint pipe and the second paint pipe, and the second paint pipe has a better spraying effect on the steel body, making rework less likely, and the first paint pipe and the second paint pipe together spray paint the side of the steel body, improving the painting efficiency of the steel body.

[0025] like Figures 1-5As shown, a steel structure painting device includes a painting box 1, through which a steel body 2 passes. A spray box 3 is located at one end of the painting box 1. A conveying pipe 5 is fixedly connected to the top of the painting box 1. The conveying pipe 5 passes through the spray box 3 and is fixedly connected to a first spray pipe 6 and a second spray pipe 7. The second spray pipe 7 is arc-shaped. There are two of each type of spray pipe. The two first spray pipes 6 and the two second spray pipes 7 form an opening that fits onto the outside of the steel body 2. Support frames 20 are provided on both sides of the painting box 1. Support rollers 21 are rotatably connected to the lower end of the support frames 20. The steel body 2 is located above the support rollers 21. Two limiting rollers 22 are rotatably connected to both sides of the support frames 20. The limiting rollers 22 are connected to... The sidewalls of the steel body 2 are fitted together. The support frame 20 is an H-shaped frame, and the steel body 2 is located inside the support frame 20. The middle of the paint box 1 has an I-shaped hole that matches the steel body 2. The steel body 2 is an I-shaped steel. The second paint spray pipe 7 is located in the middle of the steel body 2. One end of the first paint spray pipe 6 and the second paint spray pipe 7 are fixedly connected to several paint spray heads. In use, the steel body 2 passes through the middle of the paint box 1, allowing the steel body 2 to move within the paint box 1. A spray box 3 is provided at one end of the paint box 1. The top of the paint box 1 is fixedly connected to a conveying pipe 5. The conveying pipe 5 passes through the spray box 3 and is fixedly connected to the first paint spray pipe 6 and the second paint spray pipe 7. The second paint spray pipe 7 is arc-shaped. There are two of each of the first paint spray pipe 6 and the second paint spray pipe 7. Two first spray pipes 6 and two second spray pipes 7 form an opening that fits onto the outside of the steel body 2, fixing the position of the conveying pipe 5 in the paint box 1. This allows the conveying pipe 5 to simultaneously deliver paint to the first spray pipes 6 and the second spray pipes 7, resulting in better spraying of the inside of the steel body 2 by the second spray pipes 7 and reducing the need for rework. Furthermore, the first spray pipes 6 and the second spray pipes 7 work together to paint the sides of the steel body 2, improving the painting efficiency. Support frames 20 are provided on both sides of the paint box 1, with support rollers 21 rotatably connected to the lower end of each support frame 20. The steel body 2 is positioned above the support rollers 21.

The limiting rollers 22 also restrict the movement of the steel body 2, preventing it from rubbing against the support frame 20 and causing damage. The support frame 20 is H-shaped, and the steel body 2 is located within it, providing good positional control. The paint tank 1 has an I-shaped hole in the center that fits the steel body 2, allowing it to move within the tank and reducing paint evaporation during painting. The second paint spray pipe 7 is located in the center of the steel body 2.Both the first spray pipe 6 and the second spray pipe 7 have several spray heads fixedly connected to one end, resulting in a better spraying effect on the steel body 2.
