Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0087] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0088] like Figures 1-17 As shown, a rust removal device for steel bar plating includes: a unloading assembly 31, including a fixed step plate 312 and a movable step plate 313 movably disposed along the stepped end face of the fixed step plate 312, the reciprocating motion of the movable step plate 313 driving the steel bar to move to a transport vehicle 35; a loading roller conveyor 32, configured to receive the steel bar on the transport vehicle 35; a rust removal assembly 34, configured to receive the steel bar on the loading roller conveyor 32, a steel bar rotating assembly 342 driving the steel bar to rotate, a steel bar linear moving assembly 341 driving the steel bar to move axially, and a laser cleaning head 36 performing rust removal on the surface of the steel bar; a discharge roller conveyor 33, including multiple conveying assemblies disposed along the length direction of the steel bar, the multiple conveying assemblies being uniformly disposed along the length direction of the steel bar; and a collection assembly, configured to collect the rust-removed steel bar on the discharge roller conveyor.

[0089] The unloading assembly 31 includes: a storage tank 311, the bottom of which is inclined; a fixed step plate 312, the upper surface of which is provided with a first step structure 31201, the top of which is fixed with a discharge groove 31202, the width of which is twice the diameter of the reinforcing bar; the height of one end of the fixed step plate 312 near the storage tank 311 is lower than the height of the other end; and the height of the bottom of the storage tank 311 near the fixed step plate 312 is lower than the height of the other end. The storage tank 311 has multiple fixed step plates 312, which are arranged along its length. A movable step plate 313 is also present, with a second step structure 31301 matching the first step structure 31201 of the fixed step plate 312. The movable step plate 313 is movably connected to the storage tank 311, and multiple movable step plates 313 are installed between adjacent fixed step plates 312. The two sides of the first step structure 31201 are perpendicular to each other, and both sides of the first step structure 31201 are inclined to the ground. The end of the fixed step plate 312 adjacent to the storage tank 311 is located below the storage tank 311.

[0090] The movable step plate 313 is provided with a drive assembly for driving the movable step plate 313 to reciprocate along the end face of the storage tank 311 in the first step structure 31201. The drive assembly can be one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0091] The working process of the unloading assembly 31 is as follows: Bundles of steel bars are placed in the storage tank 311 by an overhead crane. The binding ropes of the steel bars are untied, and the scattered steel bars roll onto the inclined surface at the bottom of the storage tank 311 under the action of gravity. The steel bars roll onto the bottom step of the fixed step plate 312 and the movable step plate 313. Then the movable step plate 313 moves upward, driving the steel bars to move. Both sides of the step structure are inclined to the ground. The steel bars enter the upper step. When the steel bars enter the discharge groove 31202, there is only one steel bar in the discharge groove 31202. The movable step plate 313 moves with its upper end inclined. One steel bar moves on the uppermost step surface of the movable step plate 313. Each movement of the movable step plate 313 can drive one steel bar to roll out.

[0092] The specific workflow of the movable step plate 313 is as follows: Figure 5 As shown, the initial state is Figure 5 In Figure a, there is only one steel bar in the discharge groove 31202, and the moving step plate 313 moves along... Figure 5 The large arrow in Figure b moves in the direction of the large arrow (the direction of the large arrow is parallel to the end face of the adjacent storage tank 311 in the stepped structure). The moving stepped plate 313 drives the steel bar in the discharge groove 31202 to leave the discharge groove 31202. The steel bar moves along... Figure 5 Move the small arrow in the middle (b) direction to the designated position; then move step 313 along... Figure 5 The arrow in diagram b continues to move in the direction of the larger arrow, and the first step structure 31201 and the second step structure 31301 are misaligned (e.g., ...). Figure 5 (See Figure C) Each step of the second-tier structure 31301 has a steel bar that flows to a higher step of the first-tier structure 31201 (the direction of movement is as follows). Figure 5 (The small arrow in diagram c) Figure 5 As shown in Figure d, then move step plate 313 downwards (and...). Figure 5 (The large arrows in diagram b point in the opposite direction) Each step of the fixed step slab 312 has a steel bar (e.g., Figure 5 As shown in Figure e), the movable step plate 313 continues to descend. When the movable step plate 313 aligns with the stepped structure of the fixed step plate 312, the reinforcing bars on the fixed step plate 312 and the movable step plate 313 merge to form the initial state. Figure 5 The state of Figure a.

[0093] The unloading assembly 31 can also use an existing conveyor belt drive, with multiple grooves on the conveyor belt, and a scraper ensures that each groove contains only one steel bar.

[0094] Transport vehicle 35 includes:

[0095] The vehicle body 351 has a roller 353 at its lower end, which is movably connected to a first track. The first track is perpendicular to the reinforcing bar. A servo motor is provided to drive the roller 353 to rotate. A lifting platform 352 is movably connected to the vehicle body 351 along the height direction. The lifting platform 352 is driven to rise and fall by an electric cylinder or a lead screw. The lifting platform 352 has a positioning groove 35201 corresponding to the reinforcing bar. The depth of the positioning groove 35201 is greater than the radius of the reinforcing bar to prevent the reinforcing bar from shifting.

[0096] The process of transporting steel bars by transport vehicle 35 is as follows:

[0097] The positioning groove 35201 of the lifting platform 352 corresponds to the lower end of the inclined surface of the upper part of the moving step plate 313. Each time a steel bar rolls out and enters a positioning groove 35201, the servo motor of the transport vehicle 35 controls the transport vehicle 35 to move one positioning groove 35201 interval each time the moving step plate 313 moves. This continues until there is a steel bar in each positioning groove 35201. Then the lifting platform 352 is raised and the moving transport vehicle 35 is moved between the adjacent conveying components of the feeding roller conveyor 32. At this time, the steel bar is higher than the rotating roller 322, so that the positioning groove 35201 is aligned with the limiting groove. Then the lifting platform 352 is lowered so that the steel bar enters the annular groove 32201.

[0098] The feeding roller conveyor 32 includes multiple material conveying components arranged along the length of the reinforcing bars;

[0099] The material conveying assembly includes: a base 321, with adjustable support legs at the lower end of the base 321; a rotating roller 322, the axis of which is perpendicular to the axis of the reinforcing bar, with two bearings at each end of the rotating roller 322 rotatably connected to bearing seats 323, the bearing seats 323 being fixedly connected to the base 321, and multiple annular grooves 32201 arranged along the axis of the rotating roller 322 on the side wall of the rotating roller 322, the width of which matches the diameter of the reinforcing bar, and the bottom end of which is an arc-shaped surface, the arc-shaped surface design increasing the friction with the reinforcing bar and preventing slippage; and a material conveying motor 324, the housing of which is fixedly connected to the base 321, a drive pulley fixedly mounted on the output shaft of the housing of the material conveying motor 324, and a driven pulley fixedly mounted on at least one of the multiple rotating rollers 322, the drive pulley being connected to the driven pulley via a belt.

[0100] The rotating roller 322 drives the steel bars into the rust removal assembly 34. The material conveying assembly can also be a conveyor belt. The outer side of the conveyor belt is provided with a support plate with grooves. The transport vehicle 35 is located between adjacent conveyor belts.

[0101] Rust removal component 34 includes:

[0102] Two rebar rotating assemblies 342 are used to drive the rebars to rotate along the axis. Multiple rebar linear moving assemblies 341 are used to drive the rebars to move along the axial direction. These multiple assemblies 341 are evenly arranged along the axial direction and located between two rebar rotating assemblies 342. A laser cleaning head 36 is fixedly connected to a mounting frame 361. Mounting frames 361 are provided between adjacent rebar linear moving assemblies 341, with the cleaning head located above the rebar. Each mounting frame 361 has multiple laser cleaning heads 36, arranged perpendicular to the rebar's direction of movement. The rebar linear moving assemblies 341 may employ, but are not limited to, the aforementioned conveying components.

[0103] The rebar rotation assembly 342 includes: a support 34201, on which a guide groove 34206 is provided along the height direction; a movable plate 34202, on which a guide boss 34205 corresponding to the guide groove 34206 is provided, the guide boss 34205 being located inside the guide groove 34206; and a rotating wheel 34204, the axis of which is parallel to the axis of the rebar, the rotating wheel 34204 being rotatably connected to the movable plate 34202, and there are multiple rotating wheels 34204 arranged perpendicular to the direction of rebar movement. The number of movable plates 34202 is also specified. There are two moving plates 34202, with the reinforcing bars located between the rotating wheels 34204 of the two moving plates 34202; a rotating motor, with a rotating motor on each moving plate 34202, drives the rotating wheel 34204 on one moving plate 34202 to rotate, and the rotating wheels 34204 on the two moving plates 34202 rotate in opposite directions; a cylinder 34203, the housing of which is fixedly connected to the bracket 34201, and the output shaft of which is fixedly connected to the moving plate 34202; and an anti-slip rubber ring, which is installed on the outside of the rotating wheel 34204, to increase the friction between the rotating wheel 34204 and the reinforcing bar.

[0104] The working process of the rust removal component 34 is as follows: the steel bar rotates under the drive of the rotating wheel 34204 of the steel bar rotating component 342, and moves linearly under the drive of the steel bar linear moving component 341. The laser cleaning head 36 performs rust removal on the outer surface of the steel bar. The rust removal operation of the steel bar can be achieved by rotation, and continuous production can be achieved, which improves work efficiency.

[0105] The rebar rotating assembly 342 can also be a linearly driven reciprocating rotating plate structure. The reciprocating rotating plate includes a lower plate and an upper plate. The lower plate is fixedly set, and the rebar is located between the upper plate and the lower plate. The upper plate makes reciprocating motion, driving the rebar to rotate repeatedly in both directions.

Each V-shaped actuating plate is equipped with a driving component to rotate it; the driving component can be a servo motor or a swing arm driven by a hydraulic cylinder.

[0108] The V-shaped actuating plate 37 includes a deflector plate 371 and a guide plate 372. The included angle between the deflector plate 371 and the guide plate 372 is an obtuse angle. A hinge shaft 373 is provided at the connection between the deflector plate 371 and the guide plate 372. The axis of the hinge shaft 373 is lower than the axis of the reinforcing bar. When the V-shaped actuating plate 37 is in the initial position, the deflector plate 371 is horizontally positioned and located below the reinforcing bar. When the V-shaped actuating plate 37 is in the actuated position, the deflector plate 371 is tilted, with the end of the deflector plate 371 away from the guide plate 372 higher than the reinforcing bar. The guide plate 372 is also tilted, and the guide plate 371 is tilted. The end of the guide plate 372 away from the deflector plate 371 is lower than the axis of the hinge shaft 373; the hinge shaft 373 is located between the V-shaped collecting plate 38 and the conveying assembly, the height of the upper end of the V-shaped collecting plate 38 is lower than the height of the hinge shaft 373, when the V-shaped deflector plate 37 is in the deflecting position, the end of the guide plate 372 away from the deflector plate 371 is lower than the height of the upper end of the V-shaped collecting plate 38; the end of the guide plate 372 away from the deflector plate 371 corresponds to the middle position of the V-shaped collecting plate 38; the side of the V-shaped collecting plate 38 near the hinge shaft 373 is inclined downward to form a guide plate 382.

[0109] The process of collecting components is as follows:

[0110] like Figure 17 As shown, Figure 17 In the diagram, a represents the initial position of the V-shaped actuating plate 37, c represents the actuating position of the V-shaped actuating plate 37, and b represents the transition position of the V-shaped actuating plate 37. When the V-shaped actuating plate 37 is in the initial position, the actuating plate 371 is located below the reinforcing bar. When the V-shaped actuating plate 37 is rotated to the transition position, the reinforcing bar rolls to the bottom end of the V-shaped actuating plate 37. If the V-shaped actuating plate 37 is rotated to the actuating position, the reinforcing bar moves downward along the guide plate 372 and rolls into the V-shaped collecting plate 38. Through the setting of the V-shaped actuating plate 37, the reinforcing bar is buffered and its speed is reduced in the transition position. This not only reduces the impact on the V-shaped collecting plate 38, but also reduces the entanglement between the reinforcing bars.

[0111] The rust removal device also includes a hoisting assembly 39, which comprises: a column 396, with two load-bearing rails 392 fixed at the top of the column 396, located at opposite ends of the collection assembly; a movable frame 391, with both ends movably connected to the load-bearing rails 392; a U-shaped lifting frame 393, with its vertical rod horizontally positioned and a guide shaft 394 fixed on it; a guide hole on the movable frame 391 matching the guide shaft 394, the guide shaft 394 located inside the guide hole; and a lifting component for controlling the height of the U-shaped lifting frame 393. The lifting component employs, but is not limited to, existing winches. The movable frame 391 is equipped with a motor for driving its movement, the motor having gears, and a ruler on the load-bearing rails 392, with the gears meshing with the rulers.

[0112] Two limiting plates 395 are fixed on the vertical rod at the lower end of the U-shaped lifting frame 393. A collection groove is formed between the two limiting plates 395. The upper end of the limiting plate 395 is inclined away from the collection groove. The limiting plate 395 plays a limiting role for the reinforcing bars.

[0113] The working process of hoisting component 39 is as follows:

[0114] The U-shaped lifting frame 393 is located between adjacent V-shaped collecting plates 38. The moving frame 391 is moved so that the U-shaped opening end of the U-shaped lifting frame 393 is aligned with the steel bars in the V-shaped collecting plate 38, so that the steel bars in the V-shaped collecting plate 38 are above the storage position between the two limits. The U-shaped lifting frame 393 is moved upward, and the steel bars enter the storage groove until they are separated from the V-shaped collecting plate 38. Then the moving frame 391 is moved to the designated position.

[0115] A method for removing rust from steel bars for galvanizing, using a rust removal device for steel bar galvanizing, includes the following steps:

[0116] S1. The unloading assembly 31 places the steel bars into the positioning slots 35201 of the transport vehicle 35, with one steel bar placed in each positioning slot 35201. The specific process is as follows: The overhead crane places bundles of steel bars into the storage tank 311. The binding ropes of the steel bars are opened, and the scattered steel bars are on the inclined surface at the bottom of the storage tank 311. Under the action of gravity, the steel bars roll to the bottom step of the fixed step plate 312 and the moving step plate 313. Then the moving step plate 313 moves upward, driving the steel bars to move. Both sides of the step of the step structure are inclined to the ground. The steel bars enter the upper step. When the steel bars enter the discharge groove 31202, there is only one steel bar in the discharge groove 31202. The moving plate 34202 moves again. With the upper part of the moving step plate 313 inclined, one steel bar moves on the uppermost step surface of the moving step plate 313. Each movement of the moving step plate 313 can drive one steel bar to roll out.

[0117] S2. The transport vehicle 35 moves laterally to the position of the feeding assembly to lower the position of the reinforcing bar, so that the reinforcing bar enters the annular groove 32201 of the feeding roller conveyor 32, and the feeding assembly transports the reinforcing bar into the rust removal assembly 34; the specific process is as follows:

[0118] The positioning slot 35201 of the lifting platform 352 corresponds to the lower end of the inclined surface of the moving step plate 313. Each time a steel bar rolls out and enters a positioning slot 35201, the servo motor of the transport vehicle 35 controls the transport vehicle 35 to move one positioning slot 35201 interval each time the moving step plate 313 moves, until all used positioning slots 35201 contain a steel bar. Then, the lifting platform 352 rises, and the moving transport vehicle 35 moves between adjacent conveying components of the feeding roller conveyor 32. At this point, the steel bar is higher than the rotating roller 322, aligning the positioning slot 35201 with the limiting groove. Then, the lifting platform 352 is lowered, allowing the steel bar to enter the annular groove 32201.

[0119] S3. The rust removal component 34 rotates the reinforcing bar and moves it towards the discharge roller conveyor 33, while simultaneously using the laser cleaning head 36 to clean the outer surface of the reinforcing bar. The specific process is as follows: The working process of the rust removal component 34 is as follows: the reinforcing bar rotates under the drive of the rotating wheel 34204 of the reinforcing bar rotating component 342, and moves linearly under the drive of the reinforcing bar linear movement component 341. The laser cleaning head 36 performs rust removal on the outer surface of the reinforcing bar. The rust removal operation of the reinforcing bar can be achieved through rotation, and continuous production can be achieved, improving work efficiency.

[0120] S4, discharge roller conveyor 33 receives rust-removed steel bars;

[0121] S5. The collecting assembly moves the rust-removed steel bars on the discharge roller conveyor 33 to the V-shaped collecting plate 38. The specific process is as follows: When the V-shaped actuating plate 37 is in the initial position, the actuating plate 371 is located below the steel bar. When the V-shaped actuating plate 37 is rotated to the transition position, the steel bar rolls to the bottom end of the V-shaped actuating plate 37. When the V-shaped actuating plate 37 is rotated to the actuating position, the steel bar moves downward along the guide plate 372 and rolls into the V-shaped collecting plate 38. Through the setting of the V-shaped actuating plate 37, the steel bar is buffered and its speed is reduced at the transition position. This not only reduces the impact on the V-shaped collecting plate 38, but also reduces the entanglement between steel bars.

[0122] S6. The hoisting assembly 39 moves the rust-removed reinforcing bars in the V-shaped collecting plate 38 to the designated position. The specific process is as follows: The U-shaped lifting frame 393 is located between the adjacent V-shaped collecting plates 38. The moving frame 391 is moved so that the U-shaped opening end of the U-shaped lifting frame 393 is aligned with the reinforcing bars in the V-shaped collecting plate 38, so that the reinforcing bars in the V-shaped collecting plate 38 are above the storage position between the two limits. The U-shaped lifting frame 393 is moved upward, and the reinforcing bars enter the storage groove until they are removed from the V-shaped collecting plate 38. Then the moving frame 391 is moved to the designated position.

[0123] Compared to traditional manual transportation of steel bars, the installation of unloading components 31, transport vehicles 35, and collection components improves the efficiency of steel bar coating and rust removal, reduces the labor intensity of workers, and lowers production costs.
