The rust of steel strand will have an adverse effect on the working performance of steel strand and pose a safety hazard. Even the steel strand shipped by the manufacturer is generally not treated with rust prevention. It is usually sent to customers in rolls. Customers choose different rust prevention methods according to actual conditions. In addition, the steel strand sent by the manufacturer has no good protection during transportation and storage, and there will be some rust on the surface of the steel strand. Therefore, whether it is a newly shipped or in-use steel strand, rust removal is required.

[0030] Figure 1 This is a schematic diagram of the structure of a laser rust removal and maintenance device for single-row steel strands. Figure 1 As shown, and refer to Figures 2 to 4 The embodiment of the utility model provides a laser rust removal and maintenance device for a single-row steel strand. The laser rust removal and maintenance device for a single-row steel strand includes a shell 100, a traction assembly and a rust removal assembly 300.

[0031] The traction assembly is used to drive the steel strand 500 into the housing 100 and drive the steel strand 500 to continuously feed forward. The rust removal assembly 300 includes a laser rust removal device 310 and a reciprocating mechanism 320. The laser rust removal device 310 is configured to be rotatably arranged around the steel strand 500. The reciprocating mechanism 320 is configured to drive the laser rust removal device 310 to continuously reciprocate around the steel strand 500.

[0032] Specifically, a rust removal chamber is provided in the housing 100, and the laser rust removal device 310 removes rust from the steel strand 500 in the rust removal chamber, and the housing 100 is provided to prevent rust dust from splashing outward and polluting the environment during the rust removal process of the steel strand 500. Furthermore, the reciprocating rotation of the laser rust removal device 310 enables the laser rust removal device 310 to swing back and forth around the steel strand 500, so that the laser rust removal device 310 can perform reciprocating laser rust removal on the steel strand 500, thereby avoiding dead angles during the laser rust removal process, thereby avoiding repeated rust removal of the steel strand 500, and thus improving the rust removal efficiency and rust removal quality of the steel strand 500.

[0033] During operation, the steel strand 500 with rust removal is inserted into the housing 100, and the steel strand 500 is installed on the traction assembly. The traction assembly is started, and the traction assembly drives the steel strand 500 to move forward smoothly. At the same time, the laser rust removal device 310 and the reciprocating mechanism 320 are turned on, and the reciprocating mechanism 320 drives the laser rust removal device 310 to swing back and forth around the steel strand 500, and the laser rust removal device 310 performs laser rust removal on the swept area of ​​the steel strand 500. The steel strand 500 after rust removal is continuously driven by the traction assembly and extends out of the housing 100 from the front end of the housing 100.

[0034] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the reciprocating rotating mechanism 320 includes a first gear 321, a second gear 322 and a reciprocating gear 323. The reciprocating gear 323 is rotatably disposed in the housing 100 and is connected to the laser rust removal device 310 for rotating the laser rust removal device 310. The first gear 321 and the second gear 322 are both rotatably disposed in the housing 100 and mesh with each other.

[0035] A plurality of first rods 3211 are disposed on the first gear 321. The first rods 3211 are perpendicular to the first gear 321, and the plurality of first rods 3211 are evenly distributed along the axis of the first gear 321 within a preset angle of the first gear 321. The distance between two adjacent first rods 3211 is equal to the tooth pitch of the reciprocating gear 323, so that when the first gear 321 rotates, the plurality of first rods 3211 drive the first gear 321 to rotate in the first direction;

[0036] The second gear 322 is provided with a plurality of second rods 3221, which are perpendicular to the first gear 321, and the plurality of second rods 3221 are evenly distributed along the axis of the second gear 322 within a preset angle of the second gear 322. The distance between two adjacent second rods 3221 is equal to the tooth pitch of the reciprocating gear 323, so that when the second gear 322 rotates, the plurality of second rods 3221 drive the second gear 322 to rotate in the second direction, and the first direction is opposite to the second direction.

[0037] Specifically, the first rod 3211 and the second rod 3221 can be inserted into the tooth gap of the reciprocating gear 323, and the plurality of first rods 3211 and the plurality of second rods 3221 are evenly arranged at a preset angle, so that the plurality of first rods 3211 and the plurality of second rods 3221 respectively constitute an incomplete gear mechanism. Each first rod 3211 or each second rod 3221 is equivalent to a tooth.

[0038] Further, the first gear 321 and the second gear 322 are meshed with each other so that the rotation directions of the first gear 321 and the second gear 322 are opposite. When the first gear 321 rotates, the first rod 3211 drives the reciprocating gear 323 to rotate in the first direction until the first rod 3211 and the reciprocating gear 323 are disengaged. At this time, the second rod 3221 on the second gear 322 is meshed with the reciprocating gear 323 and drives the reciprocating gear 323 to rotate in the second direction until the second rod 3221 and the reciprocating gear 323 are disengaged. The reciprocating gear 323 is meshed with the first rod 3211 again, and the reciprocating gear 323 is rotated in a reciprocating cycle. Since the reciprocating gear 323 is connected to the laser rust removal device 310, the reciprocating gear 323 drives the laser rust removal device 310 to rotate reciprocatingly.

[0039] Furthermore, the first gear 321 and the second gear 322 are completely identical, so that the reciprocating gear 323 can reciprocate at the same angle, thereby enabling the laser rust removal device 310 to swing at a constant speed. The laser rust removal device 310 swings at a constant speed to remove rust from the steel strand 500 evenly.

[0040] It should be noted that, in actual use, an appropriate amount of damping needs to be added during the rotation of the reciprocating gear 323 to prevent the reciprocating gear 323 from excessively rotating and causing the first rod 3211 or the second rod 3221 to hit the reciprocating gear 323 .

[0041] In this embodiment, the reciprocating rotation mechanism 320 includes a mounting frame and a driving motor; the mounting frame is fixedly arranged at the top of the mounting cavity, and the first gear 321, the second gear 322 and the reciprocating gear 323 are all rotatably arranged on the mounting frame. The driving motor is installed on the mounting frame, and is used to drive the first gear 321 or the second gear 322 to be connected, so that the driving motor drives the first gear 321 or the second gear 322 to rotate.

[0042] Specifically, the first gear 321 and the second gear 322 are meshed with each other, and the reciprocating gear 323 can be driven to reciprocate by a driving motor, thereby achieving a simplified structure.

[0043] In this embodiment, the plurality of first rods 3211 and the plurality of second rods 3221 may be replaced by two identical incomplete gear structures.

[0044] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the laser rust removal device 310 includes a rotating seat 311 and a laser emitter 312. The rotating seat 311 is rotatably disposed in the housing 100 along the circumference of the steel strand 500 and is rotatably connected to the reciprocating rotating mechanism 320. The laser emitter 312 is mounted on the rotating seat 311.

[0045] Specifically, the rotating seat 311 is rotatably arranged on the mounting seat. Further, a rotating gear is arranged on the rotating seat 311, and the rotating gear is meshed with the reciprocating gear 323, so that the rotating seat 311 and the reciprocating gear 323 rotate synchronously. The laser reflector is used to emit a pulsed laser to clean the rust of the steel strand 500.

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the laser rust removal and maintenance device for single-row steel strands also includes an oiling box 400, which is arranged at the front side of the housing 100. Rust-proof oil is arranged in the oiling box 400. After the steel strands 500 are rust-removed, they pass through the housing 100 and then through the oiling box 400, so that the rust-proof oil adheres to the surface of the steel strands 500.

[0047] Specifically, the anti-rust oil can form a protective layer on the steel strand 500 after rust removal, preventing the surface of the steel strand 500 from contacting the air, thereby preventing the steel strand 500 from being oxidized and rusted again within a period of time, thereby achieving the effect of extending the service life of the steel strand 500. At the same time, applying the rust removal oil on the surface of the steel strand 500 can increase the aesthetics of the steel strand 500.

[0048] In this embodiment, a first oiling hole and a second oiling hole are respectively provided on the front and rear side walls of the oiling box 400; a first brush is evenly distributed circumferentially on the first oiling hole, and a second brush is evenly distributed circumferentially on the second oiling hole.

[0049] During operation, the steel strand 500 is led out from the front side of the housing 100 by the traction assembly, and enters the first oiling hole and the oiling box 400. When passing through the first oiling hole, the steel strand 500 is cleaned by the first brush, thereby cleaning dust particles on the surface of the steel strand 500. The steel strand 500 passes through the oiling box 400 from the second oiling hole, and the second brush can scrape off the excess antirust oil on the steel strand 500, so that the antirust oil is evenly attached to the surface of the steel strand 500, thereby increasing the aesthetics of the steel strand 500.

[0050] Specifically, the anti-rust oil can be replaced by anti-rust materials such as anti-rust paint.

[0051] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, there are multiple laser rust removal devices 310 and reciprocating rotating mechanisms 320. Each reciprocating rotating mechanism 320 is used to drive a laser rust removal device 310 to reciprocate. Two adjacent reciprocating rotating mechanisms 320 are configured so that the rotation directions of the two adjacent laser rust removal devices 310 are always opposite.

[0052] Specifically, the arrangement of multiple laser rust removal devices 310 can improve the rust removal efficiency of the steel strand 500, and can prevent the steel strand 500 from moving forward too fast, resulting in missed rust removal areas. Furthermore, the arrangement of two adjacent laser rust removal devices 310 rotating in opposite directions can further prevent the generation of cleaning dead corners.

[0053] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the bottom of the housing 100 is funnel-shaped, and a discharge port 170 is provided at the lowest position of the bottom of the housing 100. Specifically, the rust residue generated by the laser rust removal device 310 cleaning the steel strand 500 falls downward. The funnel-shaped setting of the bottom of the housing 100 can make the rust residue gather at the discharge port 170 and be easily discharged from the discharge port 170.

[0054] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a collection box 160 is arranged below the housing 100, the collection box 160 is connected to the discharge port 170, and a drawer 161 is movably installed inside the collection box 160. Specifically, the rust residue enters the drawer 161 of the collection box 160 from the discharge port 170, and the setting of the drawer 161 can facilitate the removal of the rust residue.

[0055] Furthermore, a handle is installed on one side of the drawer 161, and blocks are provided on both sides of the drawer 161. The handle can facilitate the drawer 161 to be pulled out from the inside of the material collection box 160, thereby facilitating the cleaning of dust and rust residue inside the drawer 161. The blocks can make the drawer 161 engage with the material collection box 160, thereby ensuring the stability of the drawer 161 when sliding inside the material collection box 160.

[0056] In some embodiments of the present invention, an electromagnet 110 is provided at the bottom of the housing 100 , and the electromagnet 110 is configured to be turned on when the laser rust removal device 310 is working.

[0057] Specifically, the electromagnet 110 is powered on and has magnetism, and can adsorb the rust residue, so that the rust residue is adsorbed on the bottom of the housing 100 to prevent the rust residue dust from flying around. Furthermore, the laser rust removal device 310 and the electromagnet 110 are electrically connected and configured to be turned on and off at the same time. When the rust removal operation on the steel strand 500 is completed, the laser rust removal device 310 is turned off, and the electromagnet 110 is turned off and loses its magnetism, and the rust residue slides downward along the inclined surface at the bottom of the housing 100 and is discharged from the discharge port 170.

[0058] In some embodiments of the present invention, Figure 2 As shown, the housing 100 is provided with a first hole 120 and a second hole 130, wherein the first hole 120 is arranged at the front side of the housing 100 and the second hole 130 is arranged at the rear side of the housing 100. The steel strand 500 enters the housing 100 from the second hole 130 and then passes through the housing 100 from the first hole 120.

[0059] The traction assembly includes a first traction wheel group 210 and a second traction wheel group 220. The first traction wheel group 210 is arranged at the front side of the housing 100, and the second traction wheel group 220 is arranged at the rear side of the housing 100. The first traction wheel group 210 and the second traction wheel group 220 are both configured to clamp the steel strand 500 and drive the steel strand 500 to move forward when rotating.

[0060] Specifically, a rubber soft film is installed in the first hole 120 and the second hole 130. When the steel strand 500 is inserted into the first hole 120 and the second hole 130, the rubber soft film contacts the outer surface of the steel strand 500, which can enable the steel strand 500 to enter and exit the shell 100 while preventing dust from floating out of the shell 100 from the inside of the first hole 120.

[0061] In this embodiment, the first traction wheel group 210 includes two rollers 211 and a traction motor 212; the two rollers 211 are parallel to each other and vertically arranged, and the two rollers 211 rotate relative to each other, and the two rollers 211 are configured to clamp the steel strand 500 to drive the steel strand 500 to feed forward when rotating. The traction motor 212 is used to drive the two rollers 211 to rotate relative to each other. Specifically, the first traction wheel group 210 and the second traction wheel group 220 have the same structure. Furthermore, each roller 211 is provided with a rubber sleeve, which can increase the friction between the roller 211 and the steel strand 500, thereby preventing the steel strand 500 from slipping during the forward movement.

[0062] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, a visual window 140 is provided on the front side wall of the housing 100, and a polarizing film is pasted on the visual window 140. Specifically, the visual window 140 can facilitate observation of the working condition of the laser rust removal device 310 in the rust removal chamber to remove rust from the steel strand 500, and the polarizing film can reduce the intensity of the laser transmitted by the device, thereby preventing the laser from causing damage to human eyes.

[0063] In some embodiments of the present invention, Figure 1 As shown, the housing 100 is provided with a one-way air inlet pipe 150 for allowing external air to enter the interior of the housing 100 , thereby preventing dust from floating out of the housing 100 from the air inlet position.

[0064] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
