Description
Technical Field
[0001] The utility model relates to the technical field of steel structure painting, in particular to a painting device for the outer surface of a steel structure. Background Art
[0002] With the rapid development of the modern construction industry, steel structures have occupied a place in the construction field with their unique advantages. However, during long-term use, steel structures often face challenges such as corrosion and wear, which not only affect their aesthetics but may also pose a threat to their structural safety. To address this challenge, painting the steel structure has become a key technology for protecting the steel structure and extending its service life.
[0003] In the prior art, a robotic arm is often used to replace manual painting operations during the painting of steel structures. At this time, it is often necessary for workers to place the steel structure to be painted at the spraying position, and then the robotic arm performs the spraying operation. After the robotic arm finishes spraying, workers need to remove the steel structure and carry it to the storage area after painting, and then perform the painting process on the next steel structure to be sprayed.
[0004] However, there are still some problems with the method of using the robotic arm in the prior art to cooperate with manual labor for steel structure spraying operations: during the spraying operation, due to the excessive distance of the steel structure in the length direction, the reach of the robotic arm at a fixed position cannot meet the spraying requirements. At the same time, the steel structure to be sprayed is placed at a fixed spraying position, and workers need to manually carry the painted steel structure to the storage area after spraying, which is time-consuming and laborious, and the automation degree of the steel structure automatic spraying equipment is relatively low. Summary of the Utility Model
[0005] Aiming at the problems in the prior art, the utility model provides a painting device for the outer surface of a steel structure with high automation degree, which solves the problem that the reach of the robotic arm is limited and automatic painting cannot be completed when spraying long steel structures in the prior art, and at the same time avoids the problem that workers need to carry the painted steel structure a certain distance to the storage area.
[0006] The technical scheme adopted by the utility model is as follows:
[0007] A steel structure outer surface coating device, comprising a coating platform and a bracket. The bracket is arranged on the coating platform for placing the steel structure to be sprayed. At least one side of the two sides of the bracket is provided with a spraying mechanism. The lower end of the bracket is provided with a transfer mechanism, and the bracket is fixedly arranged on the transfer mechanism, and the transfer mechanism can move reciprocally. Through the arranged transfer mechanism, when spraying a long steel structure is required, the transfer mechanism can drive the bracket and the steel structure on the bracket to move in the length direction, so as to adapt the spraying robotic arm. And after the spraying is completed, the transfer mechanism transports the steel structure to one side close to the storage area, avoiding the problem in the prior art that the robotic arm reach limitation causes the inability to complete automatic coating when spraying a long steel structure, and at the same time avoiding the problem that the staff needs to carry the sprayed steel structure for a certain distance to the storage area.
[0008] Preferably, a spraying mechanism is arranged on each of the two sides of the bracket. By arranging spraying mechanisms on both sides of the bracket, the spraying speed of the steel structure can be accelerated and the spraying efficiency of the steel structure can be improved.
[0009] Preferably, the transfer mechanism includes a first guide rail, the first guide rail is fixedly arranged on the coating platform, a transfer wheel is arranged on the bracket, and the transfer wheel is placed on the first guide rail and can move along the first guide rail. Through the arranged first guide rail and transfer wheel, the moving direction of the bracket can be restricted, which is convenient for moving the bracket in the preset direction.
[0010] Preferably, the transfer mechanism further includes a first motor, the first motor is fixedly arranged, the output shaft of the first motor is connected with a first speed reducer, the first speed reducer is connected with a driving sprocket, the transfer mechanism further includes a driven sprocket and a chain, the chain is meshed and connected with the driving sprocket and the driven sprocket, a connecting plate is arranged on the bracket, and the connecting plate is fixedly connected with the chain. Through the arranged first motor, driving sprocket and chain, the operation of the transfer mechanism can be set as electric control, without manual movement of the bracket by personnel, improving the automation degree of the device and reducing the labor intensity of the staff.
[0011] Preferably, the spraying mechanism includes a robotic arm and a placing table, the placing table is arranged on the coating platform, and the robotic arm is fixedly arranged on the placing table. Through the arranged robotic arm and placing table, the placing table has a certain height, which can enable the end of the robotic arm to move below the base of the robotic arm, increasing the spraying range of the robotic arm in the vertical direction.
[0012] Preferably, the height of the end face of the bracket for placing the steel structure from the coating platform is 790mm ± 200mm. By setting the height of the upper end face of the bracket, it is convenient for the staff to place and carry the steel structure at a comfortable height, avoiding the need for the staff to frequently bend down to damage the waist due to too low height, or reducing the convenience of carrying due to too high height, and at the same time, too high height increases the risk of injury to personnel when the steel structure falls on the bracket.
[0013] Preferably, the height of the upper end surface of the placement table from the painting platform is lower than the height of the upper end surface of the support from the painting platform. By setting the heights of the placement table and the support, the application range of the robotic arm for different heights of the steel structure is increased on the premise of ensuring that the robotic arm can spray the bottom end surface of the steel structure.
[0014] Preferably, the painting mechanism further includes a second guide rail disposed on the painting platform. A slider is provided below the placement table, and the slider is disposed on the second guide rail and can reciprocate on the second guide rail. The painting mechanism further includes a driving unit disposed in the placement table for driving the placement table to reciprocate on the second guide rail. By providing the second guide rail and the driving unit, the robotic arm can reciprocate in the length direction of the steel structure, and can perform separate moving spraying when the efficiencies of the two robotic arms are different due to different spraying areas and difficulties on both sides of the steel structure, improving the coherence during single-side spraying and thus ensuring the spraying quality.
[0015] Preferably, the driving unit includes a second motor. The output shaft of the second motor is connected to a second reduction gear, and the second reduction gear is connected to a gear. The driving unit further includes a rack fixedly disposed on the painting platform, and the gear is meshed with the rack. By providing the second motor, the gear, and the rack, the robotic arm can perform accurate reciprocating movement.
[0016] As can be seen from the above technical solutions, the advantages of the present utility model are as follows: Through the provided transfer mechanism, when spraying long steel structures is required, the transfer mechanism can drive the bracket and the steel structure on the bracket to move in the length direction, so as to adapt the spraying robotic arm. After spraying is completed, the transfer mechanism transports the steel structure to the side close to the storage area, avoiding the problem in the prior art that the limited reach of the robotic arm restricts automatic painting when spraying long steel structures, and also avoiding the problem that workers need to carry the sprayed steel structure a certain distance to the storage area. By providing spraying mechanisms on both sides of the bracket, the spraying speed of the steel structure can be accelerated, and the spraying efficiency of the steel structure can be improved. By providing the first guide rail and transfer wheels, the moving direction of the bracket can be restricted, facilitating the movement of the bracket in the preset direction. By providing the first motor, driving sprocket and chain, the operation of the transfer mechanism can be set to electric control, eliminating the need for manual movement of the bracket by personnel, improving the automation degree of the equipment, and reducing the labor intensity of workers. By providing the robotic arm and the placement table, and setting the placement table at a certain height, the end of the robotic arm can be moved under the base of the robotic arm, increasing the spraying range of the robotic arm in the vertical direction. By setting the height of the upper end surface of the bracket, it is convenient for workers to place and carry the steel structure at a comfortable height, avoiding the need for workers to frequently bend down, which may damage the waist due to too low a height, or reducing the convenience of handling due to too high a height. At the same time, too high a height increases the risk of injury to personnel when the steel structure falls on the bracket. By setting the height of the placement table and the bracket, the application range of the robotic arm for different heights of the steel structure is improved on the premise of ensuring that the robotic arm can spray the bottom end surface of the steel structure. By providing the second guide rail and the driving unit, the robotic arm can reciprocate in the length direction of the steel structure, and can move and spray separately when the efficiencies of the two robotic arms are different due to different spraying areas and difficulties on both sides of the steel structure, improving the coherence during single-sided spraying, and thus ensuring the spraying quality. By providing the second motor, gear and rack, the robotic arm can move accurately back and forth. BRIEF DESCRIPTION OF THE DRAWINGS

At least one side of the two sides of the support 2 is provided with a spraying mechanism, and in this embodiment, a spraying mechanism is provided on each of the two sides of the support 2. A transfer mechanism is arranged at the lower end of the support 2, and the support 2 is fixedly arranged on the transfer mechanism. The transfer mechanism can move reciprocally. With such a setting, through the provided transfer mechanism, when spraying a longer steel structure is required, the transfer mechanism can drive the support 2 and the steel structure on the support 2 to move in the length direction, so as to adapt the spraying robotic arm 12. And after the spraying is completed, the transfer mechanism transports the steel structure to one side close to the storage area, avoiding the problem in the prior art that the arm span of the robotic arm 12 is limited when spraying a longer steel structure, resulting in the inability to complete automatic coating, and at the same time avoiding the problem that the staff needs to carry the sprayed steel structure a certain distance to the storage area. By arranging spraying mechanisms on both sides of the support 2, the spraying speed of the steel structure can be accelerated, and the spraying efficiency of the steel structure can be improved.

[0031] In this embodiment, the spraying mechanism includes a robotic arm 12 and a placing table 13.
