Description

Technical Field

[0001] This utility model relates to the field of steel rust removal technology, specifically a steel structure rust removal device. Background Technology

[0002] Steel structures are building materials commonly used in construction. When steel structures are exposed to air for a long time, they will undergo an oxidation reaction. Currently, there are various methods to remove rust from rusted steel structures, such as grinding, chemical spraying, and flame rust removal.

[0003] Application number CN202420847761.X discloses a steel structure rust removal device, including a base plate; a first vertical plate fixedly connected to the top of the base plate; a second vertical plate fixedly connected to the top of the base plate; the first and second vertical plates are arranged opposite to each other; a motor is fixedly connected to the side wall of the first vertical plate away from the second vertical plate; and a first clamp is fixedly connected to the output end of the motor. This device, by incorporating an air guide duct, reduces the waste caused by rust remover drifting during water spraying, and increases the contact area between the rust remover and the steel.

[0004] However, for steel materials such as I-beams or H-beams, the corners of their inner walls are extremely prone to rust. The aforementioned devices and some existing rust removal devices cannot spray rust remover on the corners of I-beams or H-beams of different specifications, resulting in most of the rust remover being sprayed onto the flat surface of the I-beams or H-beams, thus leading to poor rust removal effect.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A steel structure rust removal device is used to remove rust from the corners of an I-beam 3. It includes a conveying device 2 and a body 1. The conveying device 2 is installed inside the body 1. The I-beam 3 is placed on the conveying device 2 and moved. A base 20 is vertically slidably connected to the inner wall of the body 1. A base 8 is horizontally slidably connected to the base 20. Two nozzles 9 are rotatably connected to the base 8. The two nozzles 9 point to the two corners on the same side of the I-beam 3. A traction component is connected between the base 8 and the base 20. An adjustment component is connected between the base 8 and the two nozzles 9.

[0027] Please see Figure 1 and Figure 2The I-beam 3 is fed into the machine body 1 through the conveying device 2. After the rust remover is sprayed, the conveying device 2 sends the I-beam 3 out. Both nozzles 9 are in an inclined state, which can focus on spraying the rust remover at the corners on the same side of the I-beam 3. In this embodiment, two nozzles 9 are set on both sides of the inner wall of the machine body 1, so that the four corners on both sides of the I-beam 3 can be sprayed simultaneously. The horizontal tilt angle of the nozzles 9 can be adjusted by the adjustment component so that the nozzles 9 can always point to the corners of the I-beam 3 after different sizes of I-beam 3 enter the machine body 1.

[0028] It should be noted that the nozzle 9 is connected to the water pump through the delivery pipe 12, and the water pump continuously delivers rust remover to the delivery pipe 12 to achieve the spraying and rust removal of the I-beam 3 by the nozzle 9.

[0029] Two connecting seats 14 are fixedly installed on the base 8. A rotating shaft 18 is fixedly connected to the side of each of the two nozzles 9. The rotating shaft 18 is rotatably connected to the connecting seat 14, and one end of the rotating shaft 18 passes through the connecting seat 14. The adjustment component includes a traction block 13, a shaft 15, a first ear seat 21 and a second ear seat 22. The traction block 13 is horizontally slidably connected to the base 8. The shaft 15 is fixedly connected to the traction block 13. The first ear seat 21 is rotatably connected to the shaft 15. The second ear seat 22 is fixedly connected to the rotating shaft 18. An elastic component is connected between the first ear seat 21 and the second ear seat 22. The elastic component includes a telescopic rod 16 and a spring 17. The telescopic rod 16 and the spring 17 are both fixedly connected between the first ear seat 21 and the second ear seat 22. The spring 17 is sleeved on the telescopic rod 16.

[0030] Please see Figure 4 and Figure 5 When adjusting the angle of the nozzle 9, the traction block 13 is first driven to move horizontally. When the traction block 13 moves away from the nozzle 9, the traction block 13 can drive the shaft 15 to move synchronously. The shaft 15 then drives the first ear seat 21 to move synchronously, and the first ear seat 21 can rotate circumferentially on the shaft 15. At this time, the distance between the first ear seat 21 and the second ear seat 22 increases, so that the telescopic rod 16 and the spring 17 can be stretched. The first ear seat 21 can drive the second ear seat 22 to rotate through the telescopic rod 16, which in turn drives the rotating shaft 18 to rotate synchronously, so that the rotating shaft 18 drives the nozzle 9 to rotate as a whole. At this time, the tilt angle of the nozzle 9 with the horizontal plane will decrease. Conversely, when the traction block 13 moves closer to the nozzle 9, the tilt angle of the nozzle 9 with the horizontal plane can be increased through the above process, thereby adapting to different specifications of I-beams 3.

[0031] A drive assembly is provided between the base 8 and the traction block 13. The drive assembly includes a second motor 10 and a second threaded rod 11. The second threaded rod 11 is rotatably connected to the base 8. The traction block 13 is threadedly connected to the second threaded rod 11 and contacts the surface of the base 8. The second motor 10 is fixedly mounted on the base 8 through a frame and connected to one end of the second threaded rod 11.

[0032] Please see Figure 4 In this embodiment, the movement of the traction block 13 is controlled by the second motor 10. The second motor 10 can drive the second threaded rod 11 to rotate, and the second threaded rod 11 can drive the traction block 13 to move horizontally on the base 8, thereby realizing the automatic adjustment of the tilt angle between the nozzle 9 and the horizontal plane.

[0033] The traction assembly includes a first motor 6 and a first threaded rod 7. The first threaded rod 7 is horizontally rotatably connected to the base 20. The base 8 is threadedly connected to the first threaded rod 7 and contacts the surface of the base 20. The first motor 6 is fixedly installed on the side of the base 20 via a frame and connected to one end of the first threaded rod 7. An electric slide table 5 is fixedly installed on the inner wall of the body 1, and the base 20 is fixedly installed on the slider of the electric slide table 5.

[0034] Please see Figure 3 In this embodiment, the first motor 6 drives the first threaded rod 7 to rotate, and the first threaded rod 7 drives the base 8 to translate horizontally. By controlling the rotation direction of the first motor 6, the base 8 can be driven to reciprocate horizontally, so that the base 8 drives the nozzle 9 to spray rust remover repeatedly on the side of the I-beam 3. The electric slide table 5 can adjust the vertical height of the nozzle 9 so that the nozzle 9 can accurately adapt to I-beams 3 of different specifications.

[0035] The bottom of the inner cavity of the machine body 1 is provided with a receiving groove 4. The conveying device 2 is a conveyor belt, which is installed inside the receiving groove 4. The I-beam 3 moves inside the machine body 1 via the conveyor belt. Both sides of the machine body 1 are provided with through grooves 19, which are used for the I-beam 3 to enter and exit the machine body 1 via the conveyor belt.

[0036] Please see Figure 1 and Figure 3 The conveyor belt can move the I-beam 3 inside the machine body 1, so that the I-beam 3 can easily enter and exit the machine body 1.

[0037] It should be noted that, in this embodiment, the specific structure and working principle of the conveyor belt, the electric slide table 5, the first motor 6 and the second motor 10 are all technical means well known to those skilled in the art, and will not be described in detail here.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
