Description

Technical Field

[0001] This invention relates to the field of rust removal and maintenance technology for steel strands, specifically to a rust removal and maintenance device for multi-row steel strands. Background Technology

[0002] Steel strand is a steel product made of multiple strands of steel wire twisted together. It is widely used in bridges, buildings, water conservancy, power, mining, and prestressed concrete structures. Due to its excellent mechanical properties, good adaptability, and corrosion resistance, steel strand plays a vital role in engineering. In bridge construction, steel strand is often used as prestressing tendons, significantly improving the load-bearing capacity of the structure, reducing material usage, and lowering costs. Its excellent elastic recovery ensures the stability and safety of bridges under heavy loads or extreme weather conditions.

[0003] To improve the load-bearing capacity of manufactured steel strands, surface rust removal and maintenance are necessary. Currently, most rust removal and maintenance devices have independent rust removal and maintenance mechanisms. This results in insufficient maintenance after rust removal, leading to secondary oxidation due to prolonged exposure to air, which affects the load-bearing capacity of the steel strands. Furthermore, current maintenance methods often involve spraying a curing agent onto the surface, but this agent tends to drip, affecting adhesion and maintenance effectiveness. Consequently, rust will still occur after prolonged use, impacting the load-bearing capacity of the steel strands. Therefore, we propose a rust removal and maintenance device for multi-row steel strands. Summary of the Invention

[0004] To address the problem that current rust removal and maintenance devices often have independent rust removal and maintenance mechanisms, resulting in insufficient maintenance after rust removal and secondary oxidation due to prolonged contact with outside air, thus affecting the load-bearing capacity of the steel strands, the present invention aims to provide a rust removal and maintenance device for multi-row steel strands.

[0054] By adopting the above technical solution, the angle of the nozzle 805 for spraying the curing agent can be adjusted, and the spraying angle can be adjusted according to different steel strands to improve the curing effect.

[0055] The left and right side walls of the box 2 are respectively provided with an inlet and an outlet. The bottom of the box 2 is provided with a groove 9 that communicates with the outlet. A collection box 10 is slidably installed in the groove 9.

[0056] By adopting the above technical solution, the steel strand can enter the box 2 and exit through the import and export, and the collection box 10 can collect the sprayed excess curing agent.

[0057] The two sets of heating rods 500 are arranged in a snake shape, are arranged in parallel, and have openings in opposite directions.

[0058] By adopting the above technical solution, the steel strand can pass between the two sets of heating rods 500, thereby completely surrounding the steel strand and improving the preheating effect.

[0059] Working principle: When rust removal and maintenance of steel strands are required, multiple rows of steel strands are conveyed into the housing 2. Under the action of the guide roller group 3, the steel strands are guided and pass through the positioning port 12. Under the action of the laser rust remover 13, the rust on the surface of the steel strands is removed. The removed rust chips fly inside the housing 2. Under the action of the chip pump 401 and the chip extraction hood 407, the rust chips are drawn into the fixed pipe 406 and then into the collection box 400 through the chip extraction pipe 402. The motor 418 drives the drive pulley 419 to rotate, and the belt 420 and the driven pulley 421 work together to rotate the drive pulley 419. The first rotating shaft 417 can be driven to rotate, the first rotating shaft 417 drives the second connecting rod 416 to rotate, the second connecting rod 416 drives the guide block 414 to move in the guide groove 415, the guide block 414 drives the first connecting rod 411 to rotate, the first connecting rod 411 drives the lifting block 413 to slide up and down in the slot 412, so that the first connecting rod 411 drives the connecting block 408 to move left and right, the connecting block 408 drives the moving rod 403 to move back and forth left and right, and the moving rod 403 can drive the fixed pipe 406 and the chip extraction cover 407 to move back and forth left and right, so as to better clean and collect rust chips;

[0060] The processed steel strand is conveyed into the preheating chamber 7 through the port 15. The heating rod 500 heats the surface of the steel strand. The preheating temperature of the steel strand is controlled by the controller. At the same time, the drive motor 510 drives the disc 509 to rotate. The disc 509 drives the fourth connecting rod 508 to rotate. The fourth connecting rod 508 drives the third connecting rod 507 to rotate. The third connecting rod 507 drives the lifting rod 506 to move up and down. The lifting rod 506 drives the extrusion block 505 to move up and down. When the extrusion block 505 moves downward, the inclined surface can extrude the extrusion groove 512, thereby extruding the slider 503. The slider 503 can stretch the spring 511. The slider 503 drives the heating rod 500 to move away from each other. Under the action of the elastic force of the spring 511, the heating rod 500 can move back and forth, which can better preheat the heating rod 500.

[0061] The preheated steel strand is transported to the curing area, enabling continuous rust removal and curing operations. The pump body 801 transports the curing agent in the curing agent tank 800 to the connecting pipe 808 through the delivery pipe 802, and then enters the nozzle 805 through the branch pipe 807. The nozzle 805 can spray the curing agent onto the steel strand. Because the steel strand is preheated before spraying the curing agent, the adhesion between the curing agent and the surface of the steel strand can be improved.

[0062] The rotary motor 1604 drives the second gear 1605 to rotate, the second gear 1605 drives the second tooth 1606 to move, the upper and lower second teeth 1606 drive the upper and lower guide plates 1603 to move away from each other, the guide plates 1603 drive the first tooth 1607 to move, so the first tooth 1607 drives the first gear 1601 to rotate in the opposite direction, the two sets of first gears 1601 respectively drive the second rotating shaft 1600 to rotate in the opposite direction, the two sets of second rotating shafts 1600 drive the auxiliary plate 804 to rotate in the opposite direction, so the upper auxiliary plate 804 rotates downward and the lower auxiliary plate 804 rotates upward, which can adjust the spraying angle of the nozzle 805. The spraying angle can be adjusted according to different steel strands to improve the maintenance effect.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
