[0002] The I-beam, also known as the steel beam, is a long steel bar with an I-shaped cross-section. At present, the two sides of the I-beam are provided with side ears with connecting holes. To prevent rust and extend the service life, the I-beam body and the side ears need to be spray-painted before being put into use.

[0003] In the prior art, in order to improve the spraying efficiency, a method of using two layers of hooks to hook one side of the I-beam is adopted for hoisting and conveying. Since the hooks only hook one side, the center of gravity of the I-beam is unbalanced during the conveying process, and it is extremely easy to shake and swing. This unstable state increases the difficulty for the operator to control the spray gun and reduces the spraying accuracy and efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that in the above-mentioned prior art, a method of using two layers of hooks to hook one side of the I-beam is adopted for hoisting and conveying. Since the hooks only hook one side, the center of gravity of the I-beam is unbalanced during the conveying process, and it is extremely easy to shake and swing.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: A paint spraying device for the surface of steel components, comprising a conveying component, a hook member one and a hook member two. Uniformly distributed conveying hooks are arranged on the conveying component; the hook member one is hooked on the conveying hook. The hook member one includes a connecting hook, and two hooks one for hooking the two sides of the I-beam are arranged on the connecting hook; the hook member two is used for connecting two I-beams, and the hook member two includes a fixed pipe, and two hooks two are connected to both ends of the fixed pipe.

[0027] Please refer to Figures 1-5, a paint spraying device for the surface of steel members, characterized by comprising a conveying component 1, a first hook member 2 and a second hook member 3. Uniformly distributed conveying hooks 11 are arranged on the conveying component 1. The conveying component 1 is a prior art and will not be elaborated herein.

[0028] The first hook member 2 is hooked on the conveying hook 11. The first hook member 2 includes a connecting hook 21 which is hooked on the conveying hook 11. Two first hooks 22 for hooking on both sides of the I-beam are arranged on the connecting hook 21. The lower ends of the first hooks 22 are hooked on the connecting holes of the I-beam, so that the forces on both sides of the I-beam are evenly distributed, avoiding the problem of center-of-gravity imbalance caused by single-sided hooking. The connecting hook 21 includes an upper hook body 211 and a cross bar 212. Lower hook bodies 213 are provided at both ends of the cross bar 212. The first hooks 22 are hooked on the lower hook bodies 213. The lower hook bodies 213 are bent inwardly. The upper hook body 211 is connected to the center of the cross bar 212. By adding the first hooks 22, the connection between the connecting hook 21 and the conveying hook 11, the connection between the upper ends of the first hooks 22 and the lower hook bodies 213, and the connection between the lower ends of the first hooks 22 and the I-beam are located in the same plane, forming a stable three-point force structure, effectively reducing the shaking and swinging of the I-beam during conveying, and providing a stable workpiece state for the spraying operation.

[0029] The second hook member 3 is used to connect two I-beams. The two I-beams are distributed vertically. The upper side of the second hook member 3 is hooked on the I-beam, and the lower side of the second hook member 3 is also hooked on the I-beam. The second hook member 3 includes a fixed pipe 31. Hook members 32 are connected to both ends of the fixed pipe 31. The fixed pipe 31 is a loop-shaped pipe. One end of the hook member 32 has an anti-disengagement arc portion 321 which makes the hook member 32 unable to move along the length direction of the fixed pipe 31 and also makes the second hook member 3 easy to use. The other end of the hook member 32 is hooked on the I-beam. The other end of the hook member 32 has a hook. The connection parts of the first hook member 2 and the second hook member 3 are located in the same vertical plane, increasing the self-stability of the first hook member 2 and the second hook member 3, and the self-stability further increases the stability of the I-beam.

[0030] In order to further increase the stability of the two layers of I-beams, a tightening device 4 is arranged between the two fixed pipes 31. By means of the tightening device 4, the fixed pipes 31 are made to approach each other, so that the second hook member 3 is in a tensioned state transversely, thereby achieving the purpose of further stabilizing the two layers of I-beams. The tightening device 4 includes an installation box 41. A motor 42 is installed inside the installation box 41. The motor 42 has its own shaft locking mechanism. A gear 43 is fixed to the output end of the motor 42. Both sides of the gear 43 are engaged with a rack 44. The rack 44 extends out of the installation box 41. One end of the rack 44 is fixed with a fixing plate 45. The fixing plate 45 is fixedly connected to the fixed pipe 31. A slide rail 46 is fixed inside the installation box 41. A first chute 461 is formed on the slide rail 46. The rack 44 is in sliding fit with the slide rail 46. The slide rail 46 limits and supports the rack 44. Through the slide rail 46, the rack 44 and the fixing plate 45, the fixed pipe 31 and the installation box 41 are in a fixed state longitudinally. When the motor 42 is not started, through the shaft locking mechanism of the motor 42 itself, the fixed pipe 31 and the installation box 41 are also in a fixed state transversely. There is a battery for power supply inside the installation box 41. The battery charging port is installed on the installation box 41, and the charging port is blocked by a shielding plate to prevent the entry of paint. The battery is located below the rack. The shielding plate is connected to the installation box 41 through a torsion spring. This is the prior art, and the torsion spring is not shown in the figure.

[0031] A second chute 462 is formed on the slide rail 46. A slider 47 is fixed to the fixing plate 45. The slider 47 is in sliding fit with the second chute 462. Through the second chute 462 and the slider 47, the fixed pipe 31 and the installation box 41 are more stable.

[0032] The fixed pipe 31 supports the installation box 41 through the fixing plate 45, the rack 44 and the slider 47. The rack 44 not only has the function of pulling the fixed pipe 31, but also has the function of supporting the installation box 41 through the slide rail 46. Through this hard support, the fixed pipe 31 is stable when approaching or moving away from each other.

[0033] Through grooves through which the rack 44 and the slider 47 pass are formed on the installation box 41. The two through grooves are different. When the two fixed pipes 31 are tightened, the fixing plate 45 fits with the installation box 41 to block the through grooves, avoiding paint from contaminating the rack 44 and the slider 47, reducing jamming or wear of the components caused by paint accumulation, ensuring the long-term stable operation of the tightening device, and reducing the maintenance cost.

[0034] To increase the heat dissipation of the motor 42, the upper end of the installation box 41 has a cover plate 411. Vertical plates 48 are fixed to both ends of the cover plate 411. A horizontal plate 49 is fixed to the lower ends of the vertical plates 48. The horizontal plate 49 is fixed to the inner wall of the installation box 41. Vent holes are formed on the vertical plates 48. The horizontal plate 49 and the vertical plates 48 are located inside the installation box 41. By opening the vent holes on the vertical plates 48, it is not easy for paint to spray onto the vent holes, which is beneficial to maintaining the fluidity of the vent holes.

[0035] When in use, first hook the upper hook body 211 on the conveying hook 11, then hook the upper ends of the two hooks 22 on the lower hook body, and hook the lower ends on the I-beam, and then hook the hooks 2 32 at both ends of the fixed tube 31 on the two I-beams respectively. After the two I-beams are suspended in the air, start the motor 42 to rotate the gear 43, and the gear 43 moves the two racks 44, so that the two fixed plates 45 bring the fixed tubes 31 closer to each other and tighten them in the horizontal direction. When the fixed plates 45 contact the installation box 41, they stop, forming a lateral pulling force on the two layers of I-beams, effectively offsetting the shaking that may occur during the transmission process.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
