Description

Technical Field

[0001] This utility model relates to the technical field of anti-corrosion treatment equipment for steel strands, and in particular to an automated spraying bracket for anti-corrosion coating of prestressed steel strands. Background Technology

[0002] In modern construction and bridge engineering, prestressed steel strands, with their high strength and toughness, have become crucial load-bearing components and are widely used in various large-scale engineering structures. However, steel strands are highly susceptible to corrosion due to long-term exposure to complex environments such as the atmosphere, rainwater, and acids and alkalis. Accelerated corrosion severely weakens the mechanical properties of the steel strands, threatening the safety and durability of the engineering structure and significantly shortening its service life. Therefore, applying anti-corrosion coating to prestressed steel strands is a vital step in ensuring project quality and safety.

[0003] Existing automated spraying racks require the coating to dry naturally after spraying the steel strands, which makes it inconvenient to rewind the steel strands in a timely manner. Direct rewinding will cause the layers of the steel strands to stick together and damage the coating structure. If the coating is allowed to dry completely before rewinding, it will occupy a lot of production space and cause serious delays in the production process. Utility Model Content

Direct rewinding will cause the layers of the steel strands to stick together and damage the coating structure. If the coating is left to dry completely before rewinding, it will occupy a lot of production space and cause serious delays in the production process. Therefore, an automated spraying bracket for anti-corrosion coating of prestressed steel strands is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automated spraying bracket for anti-corrosion coating of prestressed steel strands, comprising an automated spraying assembly, wherein the automated spraying assembly is provided with a clamping assembly and a drying assembly, the automated spraying assembly includes a spraying frame and a spraying ring, a telescopic hose is connected to the side of the spraying ring, a pump is installed at one end of the telescopic hose, a storage box is installed at the bottom of the pump, the drying assembly includes a support frame, multiple fans are distributed on the support frame, and a protective frame is provided on the outside of the fans.

[0006] Preferably, the clamping assembly includes a mounting frame, a first clamping roller is installed inside the mounting frame, movable slots are provided on both sides of the mounting frame, a connecting block is installed inside the movable slot, a second clamping roller is installed on the side of the connecting block, and a second electric push rod is connected to the top of the connecting block.

[0007] Preferably, a translation motor is installed on the top of the spraying frame, a threaded rod is installed at one end of the translation motor, and a movable frame is threadedly connected to the outer side of the threaded rod.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, multiple fans work to generate high-speed airflow, which helps to accelerate the convection speed of air on the surface of the steel strand, improves the drying efficiency, and enables the steel strand to be wound up in time. This avoids the situation of occupying a lot of production space due to waiting for the coating to dry naturally, and at the same time improves work efficiency.

[0013] 2. In this utility model, the extension and retraction of the second electric push rod facilitates the lifting and lowering adjustment of the connecting block inside the moving groove. This allows for adjustment of the distance between the second and first pinch rollers according to the size of the steel strand, thereby enabling the steel strand to be pinched and fed.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: an automated spraying bracket for anti-corrosion coating of prestressed steel strands, including an automated spraying assembly (1), wherein the automated spraying assembly (1) is provided with a clamping assembly (2) and a drying assembly (3), the automated spraying assembly (1) includes a spraying frame (105) and a spraying ring (111), a telescopic hose (112) is connected to the side of the spraying ring (111), a pump (113) is installed at one end of the telescopic hose (112), and a pump (113) is installed at the bottom of the pump (113). The drying assembly (3) includes a storage bin (114) and a support frame (301). Multiple fans (303) are distributed on the support frame (301). A protective frame (302) is provided on the outside of the fans (303). A base (101) is installed at the bottom of the spraying frame (105). A feed roller (102) is installed at one end of the top of the base (101). A take-up roller (103) is installed at the other end of the top of the base (101). An electric motor (104) is installed at one end of the take-up roller (103).

[0022] In this embodiment, the threaded rod (107) is driven to rotate by the translation motor (108), which facilitates the movement of the moving frame (106). At the same time, the height is adjusted by the first electric push rod (109), which facilitates timely adjustment of the position of the spraying ring (111). The anti-corrosion coating is drawn from the storage box (114) by the pump (113) and transported to the inside of the spraying ring (111) through the telescopic hose (112). The coating is then sprayed out through multiple nozzles, which facilitates the automated spraying of the steel strands passing through the inside of the spraying ring (111). Then, multiple fans (303) work to generate high-speed airflow, which helps to accelerate the convection speed of the air on the surface of the steel strands, improves the drying efficiency, and enables the steel strands to be wound up in time. This avoids the situation of occupying a lot of production space due to waiting for the coating to dry naturally, and improves the work efficiency. The winding roller (103) is driven to rotate by the electric motor (104), which facilitates the winding of the dried steel strands.

[0023] Example 2: As Figures 1-4 As shown, the clamping assembly (2) includes a mounting frame (201), a first clamping roller (202) is installed inside the mounting frame (201), a moving groove is provided on both sides of the mounting frame (201), a connecting block (204) is installed inside the moving groove, a second clamping roller (203) is installed on the side of the connecting block (204), a second electric push rod (205) is connected to the top of the connecting block (204), a translation motor (108) is installed on the top of the spraying frame (105), a threaded rod (107) is installed at one end of the translation motor (108), a moving frame (106) is threaded to the outer side of the threaded rod (107), a first electric push rod (109) is connected to the bottom of the moving frame (106), a connecting frame (110) is connected to the output end of the first electric push rod (109), and a spraying ring (111) is set on the connecting frame (110).

[0024] In this embodiment, the extension and retraction of the second electric push rod (205) facilitates the lifting and lowering adjustment of the connecting block (204) inside the moving groove, and makes it easy to adjust the distance between the second pinch roller (203) and the first pinch roller (202) according to the size of the steel strand, thereby achieving the pinching and feeding of the steel strand, so that it maintains a stable running trajectory during the spraying and drying process, reducing the occurrence of deviation, shaking and other situations, thereby improving work efficiency.

[0025] The working principle of this embodiment is as follows: In use, the steel strand spool is first placed on the pay-off roller (102). The second electric push rod (205) extends and retracts, which helps to push the connecting block (204) to rise and fall inside the moving groove. This facilitates the adjustment of the distance between the second clamping roller (203) and the first clamping roller (202) according to the size of the steel strand, thereby clamping and feeding the steel strand. Then, the threaded rod (107) is electrically driven by the translation motor (108) to rotate, which helps to move the moving frame (106). At the same time, the height is adjusted in conjunction with the first electric push rod (109), which facilitates the movement of the moving frame (106). The position of the spraying ring (111) is adjusted in time, and the anti-corrosion coating inside the storage box (114) is drawn by the pump (113) and transported to the inside of the spraying ring (111) through the telescopic hose (112). The coating is then sprayed out through multiple nozzles, which is conducive to the automated spraying of the steel strands passing through the inside of the spraying ring (111). Then, multiple fans (303) work to generate high-speed airflow, which is conducive to accelerating the convection speed of the air on the surface of the steel strands and improving the drying efficiency. Finally, the winding roller (103) is electrically driven by the motor (104) to rotate, which is conducive to winding up the dried steel strands.

[0026] The wire feeding roller 102, take-up roller 103, motor 104, threaded rod 107, translation motor 108, first electric push rod 109, and second electric push rod 205 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the wire feeding roller 102, take-up roller 103, motor 104, threaded rod 107, translation motor 108, first electric push rod 109, and second electric push rod 205 will not be explained in detail.
