AI Technical Summary
In the existing technology, when using a steel structure factory painting robot to paint the surface of I-beams, the existing painting equipment cannot paint the surface of I-beams located at high positions. The existing technology cannot achieve simultaneous multi-faceted painting. While painting I-beams at high positions is more convenient, it is not possible to perform simultaneous multi-faceted painting on horizontally placed steel structures over long distances, which may easily affect the health of construction workers.
Design a multi-faceted spraying industrial robot with a steel structure. The robot moves the spraying components by walking, and uses a lifting column and a dual-axis motor to fit the spraying components onto the outside of the steel structure. Multi-faceted spraying is achieved through a linkage mechanism and a feeding component. The spraying position is adjusted by atomizing nozzles to avoid blind spots, and excess paint is collected through a recovery chamber to purify the spraying environment.
It enables multi-faceted spraying of steel structures, avoids blind spots in spraying, improves spraying efficiency and construction safety, and reduces the health impact on construction workers.

Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of robots, and particularly relates to a multi-surface spraying industrial robot for steel structures. BACKGROUND
[0002] Some steel structure workshops need to use a large number of I-beams during construction. In order to improve the fireproofing capacity of these steel components, fireproofing paint needs to be sprayed on the surfaces of the I-beams. Since the I-beams are in the shape of an I, when spraying, the surfaces of the two sides of the groove also need to be sprayed in addition to the groove. However, the existing robot spraying can only be partially sprayed.
[0003] After searching, it is found that in the prior art, a steel structure fireproofing paint spraying robot is disclosed in Chinese Patent Publication No. CN218190504U, authorized on January 3, 2023. Two drive wheel sets are arranged on the two sides of each of the two moving bodies, and an adsorption mechanism is arranged on the inner side of each of the two moving bodies. The adsorption mechanism is used to adsorb the moving body on the surface of the object to be sprayed. A plurality of push rods are slidably installed on the outer side of the first moving body in parallel. A spraying module is fixedly installed between the ends of the push rods away from the second moving body. A drive module is arranged on the second moving body. The other ends of the push rods are connected to the drive module. The robot can move in the groove of the I-beam by means of the two moving bodies with adsorption mechanisms and drive wheel sets, so that the spraying module on the robot can spray the surface of the I-beam. It is more convenient to spray some I-beams at high places.
[0004] However, the device still has the following defects: although it is more convenient to spray some I-beams at high places, it cannot perform synchronous spraying of multiple surfaces during long-distance spraying of horizontally placed steel structures to be sprayed, which can easily affect the health of construction personnel in an open spraying environment and is not conducive to long-time spraying operation.

[0054] The pneumatic valve 113 is communicated with the prepared paint supply pipe, and the compressed air enters the liquid storage shell 111 under the action of the pneumatic valve 113, so as to increase the flow rate of the paint, and when the several groups of electromagnetic valves 112 are opened, the prepared paint enters the first atomizing nozzle 317, the second atomizing nozzle 326 and the third atomizing nozzle 336 in sequence;
[0055] The output end of the first motor 3110 drives the second screw rod 319 to rotate, so that the first air pipe 316 drives the several groups of first atomizing nozzles 317 to move horizontally along the radial direction of the second screw rod 319, so as to adjust the spraying position of different positions of the two side walls of the steel structure body 4, and avoid the occurrence of the blind area of spraying;
[0056] The second atomizing nozzles 326 of the two groups of second air pipes 325 on the upper cover plate 321 and the third atomizing nozzles 336 of the two groups of third air pipes 335 on the lower cover plate 331 can spray the prepared paint to different positions on the upper and lower surfaces of the steel structure body 4, so as to avoid the occurrence of a spraying blind area.
[0057] The paint dropped from the steel structure body 4 after spraying can be stored by using the recovery pipe 334 in cooperation with the storage box 34 through the recovery cavity 333 in the inner wall of the lower cover plate 331, and the spraying ring 311, the upper cover plate 321 and the lower cover plate 331 are rotatably connected to the top of the spraying ring 311 with the first linkage shaft 322 as the center and to the bottom of the spraying ring 311 with the second linkage shaft 332 as the center, so that the cylindrical structure formed by the spraying ring 311, the upper cover plate 321 and the lower cover plate 331 can concentrate the excess paint into the recovery cavity 333.
[0058] During the horizontal movement of the first atomizing nozzles 317, the second atomizing nozzles 326 and the third atomizing nozzles 336 to different positions on the steel structure body 4 after adjusting the walking track, the air suction pump 118 and the air outlet pump 119 can be used in cooperation to accelerate the air-drying speed of the paint on the steel structure body after spraying by spraying the gas in the several groups of through holes 116 on one side under the action of the air outlet pump 119, and then using the adsorption force generated by the air suction pump 118 to adsorb the gas in the several groups of through holes 116 on the other side after spraying the paint on the steel structure body, so as to purify the environment after spraying the paint on the steel structure body 4.
