Description

Technical Field

[0001] The invention relates to the technical field of laser rust removal, in particular to a laser rust removal device for prestressed materials of high-speed railway sleepers. Background Art

[0002] The prestressed material of sleepers in the railway field is mainly steel bars. When this material is used to produce sleepers, the rust on its surface will reduce its bonding strength and affect the pouring quality of concrete. Therefore, it is necessary to remove rust from its surface. The sleepers used in high-speed railways are mainly integral sleepers, and their manufacturing requires higher-precision rust removal to ensure that the quality of each part of the sleeper is the same, thereby ensuring the smoothness of the track. Traditional rust removal methods will leave scratches or other damage on the surface of components, affecting the performance and service life of the components. Therefore, the existing main method of rust removal is to use laser rust removal to treat them. Laser rust removal can focus energy on the rust layer, so that the rust layer is instantly vaporized or peeled off, effectively avoiding excessive damage to the metal matrix, thereby completing the rust removal task. The existing prestressed material cleaning mostly uses laser rust removal machines or manual handheld laser probes for cleaning and rust removal. During the use of the laser rust removal machine, a single steel bar is placed in the machine, the machine rotates and drives the steel bar to be transported inward, and the surface of the steel bar is laser rusted. However, this type of rust removal machine can only process a single steel bar, and the efficiency is too low. At the same time, when the steel bar is processed by a manual handheld laser probe, the bundled steel bars need to be split and leveled. During the disassembly process, the steel bars will cross and tangle, resulting in mutual shielding between the steel bars, so that the steel bars located on the lower side cannot be completely irradiated by the laser, resulting in incomplete rust removal of the steel bars, thereby affecting the subsequent sleeper production.

[0039] In the above scheme, a method of leveling steel bars is proposed, the purpose of which is to reduce the intersection and obstruction between steel bars and improve the quality of laser rust removal; the transmission column 21 can be telescopic to help the scissors-type telescopic frame 22 move up and down; the scissors-type telescopic frame 22 is a double scissors structure, and the double scissors structure enables the leveling shell 23 to move more smoothly; the lower side of the leveling shell 23 is made of wear-resistant material, which can reduce the loss of the leveling shell 23 during leveling.

[0040] like Figure 5-Figure 8 As shown, the clamping assembly includes: an extrusion bar 31, which is slidably connected to the sliding shell 10 and is used to push the scissor-type telescopic frame 22 to move; two inclined slot plates 32, which are slidably connected to the telescopic ends of the adjacent scissor-type telescopic frame 22, and the inclined slot plates 32 are slidably connected to the leveling shell 23. Two inclined slots are arranged on the inclined slot plate 32, and the two inclined slots on the inclined slot plate 32 are slidably connected to the pushing blocks 33; the number of extrusion rollers 331 is consistent with the number of the pushing blocks 33, and they are respectively rotatably connected to the adjacent pushing blocks 33, and an elastic member 34 is arranged between the pushing blocks 33 and the leveling shell 23; there is an angle between the central axis of the extrusion roller 331 and the center line of the pushing block 33, which is used to clamp the steel bars and apply extrusion force.

[0041] In the above scheme, a method of clamping steel bars is proposed, the purpose of which is to reduce the gap between the steel bars, straighten the elastically deformed steel bars, improve the utilization rate of the laser, and improve the efficiency of laser rust removal; the extrusion strip 31 is made of wear-resistant material, which is used to reduce loss during extrusion and rubbing; the distance between the two inclined grooves on the inclined groove plate 32 gradually decreases from top to bottom; the elastic member 34 is a spring, which is used to reset the push block 33; the extrusion roller 331 is inclined downward, which is used to generate an extrusion force on the steel bars and press the steel bars downward to prevent the steel bars from being squeezed inward and causing lamination.

[0042] like Figure 5-Figure 7 As shown, the driving assembly includes: a first motor 24, which is arranged on the T-shaped shell 9, and the output shaft of the first motor 24 is provided with a one-way gear 25; two transmission racks 26, which are respectively fixed to adjacent transmission columns 21, and the transmission racks 26 are meshed with the one-way gear 25; a cam wheel 27, which is fixed to the output shaft of the first motor 24; two sliding plates 28, which are both slidably connected to the T-shaped shell 9 and fixed to the sliding shell 10, and are respectively located on both sides of the cam wheel 27, and the cam wheel 27 squeezes the two sliding plates 28.

[0043] In the above scheme, the output shaft of the first motor 24 drives the one-way gear 25 to rotate, and the one-way gear 25 drives the transmission rack 26 to move toward each other. When the transmission rack 26 is reset, the transmission rack 26 moves backwards, and the outer ring of the one-way gear 25 is not affected by the output shaft of the first motor 24 and rotates; the two sliding plates 28 can slide together and reciprocate with the cam wheel 27 at the same time.

[0044] like Figure 4 As shown, an arc groove 41 is provided on the limiting plate 5, and the arc groove 41 limits the laser probe 7. A soft material is provided at the connection between the laser probe 7 and the threaded transmission rod 601.

[0045] In the above scheme, the two sides of the arc groove 41 are inclined grooves with arcs, which are used to make the laser probe 7 swing and improve the quality of steel bar rust removal; the soft material in the connection area between the laser probe 7 and the threaded transmission rod 601 is rubber, which is used to make the laser probe 7 swing normally.

[0046] like Figure 9-12 As shown, it also includes: a sliding frame 50, which is fixed to the lifting shell 4; there are two adjusting plates 51, both of which are slidably connected to the sliding frame 50, and an L-shaped groove is provided on the adjusting plate 51, and the end of the threaded transmission rod 601 away from the electric rotating rod 6 slides in the L-shaped groove; there are two extrusion plates 52, which are respectively fixed to adjacent adjustment plates 51, and the extrusion plates 52 are slidably connected to the lifting shell 4 and the sliding frame 50.

[0047] In the above scheme, the initial state of the adjustment plate 51 is a staggered state, the extrusion plate 52 on the left is higher than the extrusion plate 52 on the right, the lower end of the extrusion plate 52 is a long strip, and the extrusion plate 52 is located at the end of the steel bar, squeezing the end of the steel bar downward so that it can be lowered to better extrude the steel bar; the adjustment plate 51 can change its own position according to the position of the laser probe 7, thereby adjusting the extrusion plate 52, so that the laser probe 7 can more completely clean the rust on the steel bar.

[0048] like Figure 10-12 As shown, it also includes: a first extrusion block 61, fixedly connected to the end of the threaded transmission rod 601 away from the electric rotating rod 6; two second connecting rods 62, which are slidably connected to the first connecting rod 8 respectively, and the second connecting rod 62 is fixedly connected to the leveling shell 23. A second extrusion block 621 is fixedly connected to the second connecting rod 62, and the first extrusion block 61 is used to extrude the second extrusion block 621; a third extrusion block 63, fixedly connected to the first connecting rod 8, and the second extrusion block 621 is used to extrude the third extrusion block 63; a clamping column 64, fixedly connected to the first connecting rod 8, the third extrusion block 63 and the clamping column 64 are respectively located on both sides of the first connecting rod 8, and a clamping groove 65 is provided on the lifting shell 4, and the clamping column 64 slides in the clamping groove 65.

[0049] In the above scheme, the two second connecting rods 62 are respectively located on both sides of the first connecting rod 8, and the front view projection of the second extrusion block 621 and the third extrusion block 63 is a triangle. When the first extrusion block 61 contacts the second extrusion block 621, the hypotenuse of the projected triangle fits with the hypotenuse edge of the first extrusion block 61, so that the first extrusion block 61 can better extrude and push the second extrusion block 621 and the third extrusion block 63; there are two clamping columns 64 and two clamping grooves 65 to ensure that the first connecting rod 8 and its parts do not rotate and slide stably on the clamping groove 65.

[0050] When using the device to perform laser rust removal on steel bars, the operator first places the whole bundle of steel bars on the bracket 1 and simply flattens it, and then the operator starts the hydraulic push rod 2, the telescopic end of the hydraulic push rod 2 pushes the connecting frame 3 to move downward, the connecting frame 3 pushes the lifting shell 4 to move downward, the lifting shell 4 drives the first connecting rod 8 to move downward, the extrusion plate 52 moves downward under the action of gravity, the first connecting rod 8 drives the T-shaped shell 9 to move downward, the T-shaped shell 9 drives the sliding shell 10 to move downward, the sliding shell 10 drives the extrusion bar 31 to move downward, When the extrusion bar 31 moves downward to contact the steel bar and generate extrusion pressure, the extrusion plate 52 on the right side contacts and squeezes the steel bar. At this time, the operator starts the first motor 24. The output shaft of the first motor 24 drives the cam wheel 27 to rotate. The cam wheel 27 squeezes and pushes the sliding plates 28 on both sides. The sliding plates 28 slide in the T-shaped shell 9, and the two sliding plates 28 drive the sliding shell 10 to slide back and forth under the squeezing action of the cam wheel 27. The sliding shell 10 drives the extrusion bar 31 to move back and forth, so that the extrusion bar 31 squeezes and rubs the steel bar.

[0051] During the process of rubbing and squeezing the steel bars, the telescopic end of the hydraulic push rod 2 still gradually moves downward, and the squeezing bar 31 rubs and squeezes the steel bars, so that the bundled steel bars are gradually dispersed and the steel bar stacking height is reduced. Finally, the steel bars are rubbed and squeezed into one layer. When the stacked steel bars are dispersed into one layer, the hydraulic push rod 2 reaches the set telescopic length and closes automatically.

[0052] When the first motor 24 is started, the first motor 24 drives the rotating gear 73 to rotate, the rotating gear 73 drives the transmission rack 26 to move, the transmission rack 26 drives the transmission column 21 to move in the direction close to the first motor 24, and the transmission column 21 pushes the scissors-type telescopic frame 22. The two telescopic ends of the scissors-type telescopic frame 22 respectively drive the adjacent leveling shells 23 to expand to the left and right sides. At this time, the leveling shell 23 and the steel bars generate an extrusion force. The leveling shell 23 expands to the left and right sides and squeezes and pushes the steel bars, so that the crossed steel bars can be separated, reducing the obstruction of the steel bars, and ensuring that the steel bars are laid flat on the bracket 1 in a single layer.

[0053] When the extrusion bar 31 extrudes the steel bar, the extrusion bar 31 will be relatively displaced with the sliding shell 10, the extrusion bar 31 moves upward and pushes the scissors-type telescopic frame 22 to move upward, the scissors-type telescopic frame 22 drives the inclined slot plate 32 to move upward, the inclined slot plate 32 pushes the pushing block 33 to move through the inclined slot thereon, the pushing block 33 drives the extrusion roller 331 to move toward the direction close to the first motor 24 and squeeze the elastic member 34, so that the extrusion roller 331 can extrude the steel bar, thereby shortening the gap between the steel bars, reducing the waste of laser irradiation area, and allowing the laser to act on the steel bar more.

[0054] When the scissor-type telescopic frame 22 drives the leveling shell 23 to fully open, the operator turns off the first motor 24, and then starts the electric rotating rod 6 and the laser probe 7. The electric rotating rod 6 drives the threaded transmission rod 601 to move, and the threaded transmission rod 601 drives the laser probe 7 to move. The limiting groove 501 and the arc groove 41 on the limiting plate 5 jointly limit the laser probe 7. Since a friction plate is installed in the limiting groove 501, the laser probe 7 moves along the oblique groove on the left side of the arc groove 41 driven by the threaded transmission rod 601, so that the laser probe 7 swings to the right with the laser probe 7 and the protrusion sliding in the limiting groove 501 as the center, and gradually makes the laser probe 7 become a vertical downward state.

[0055] During the swinging process of the laser probe 7, the laser probe 7 performs laser rust removal on the left end of the steel bar, and the threaded transmission rod 601 slides from the leftmost end in the L-shaped groove on the left adjustment plate 51 to the connection between the vertical part and the horizontal part of the L-shaped groove, and the threaded transmission rod 601 slides and pushes the left adjustment plate 51 to slide downward on the sliding frame 50, and the left adjustment plate 51 drives the left extrusion plate 52 to slide downward. When the laser probe 7 is vertically downward, the laser probe 7 is at the connection between the left oblique groove and the straight groove in the arc groove 41, and the threaded transmission rod 601 reaches the left connection between the vertical part and the horizontal part of the L-shaped groove on the left adjustment plate 51, and the left extrusion plate 52 stops moving downward and contacts and squeezes the steel bar.

[0056] During the process of the laser probe 7 moving to the right along the straight groove on the arc groove 41, the laser probe 7 continues to remove rust from the surface of the steel bar, and the threaded transmission rod 601 drives the laser probe 7 and the first extrusion block 61 to move to the right. When the first extrusion block 61 contacts the second extrusion block 621 on the left, the first extrusion block 61 squeezes and pushes the second extrusion block 621 on the left to move to the right, and the second extrusion block 621 on the left drives the second connecting rod 62 on the left to move to the right. The second connecting rod 62 on the left drives the leveling shell 23 on the left and its internal parts to move to the right. The leveling shell 23 on the left squeezes and pushes the scissor-type telescopic frame 22, and the transmission rack 26 drives the one-way The gear 25 reverses and the scissor-type telescopic frame 22 contracts. When the second extrusion block 621 on the left contacts the third extrusion block 63, the leveling shells 23 on both sides are contracted. At this time, the scissor-type telescopic frame 22 contracts and resets. The second extrusion block 621 on the left and the second extrusion block 621 on the right both contact the third extrusion block 63. The second extrusion block 621 on the left drives the third extrusion block 63 and the second extrusion block 621 on the right to move right together. The third extrusion block 63 drives the first connecting rod 8 to move right. The first connecting rod 8 drives the clamping column 64 and the T-shaped shell 9 and the parts thereon to move right. The clamping column 64 slides in the clamping groove 65.

[0057] When the threaded transmission rod 601 reaches the connection between the vertical part and the horizontal part of the L-shaped groove on the right adjustment plate 51, the laser probe 7 is located at the connection between the oblique groove and the straight groove on the right side of the arc groove 41, and the clamping column 64 is located at the connection between the oblique groove and the straight groove on the right side of the clamping groove 65. The arc groove 41 guides the laser probe 7, causing the laser probe 7 to swing to the right, gradually causing the laser probe 7 to become tilted to the right.

[0058] As the laser probe 7 gradually tilts to the right, the threaded transmission rod 601 begins to push the right adjustment plate 51 to slide upward, and the right adjustment plate 51 drives the right extrusion plate 52 to move upward, so that the right extrusion plate 52 loses contact with the right end of the steel bar, so that the laser probe 7 can irradiate the right end of the steel bar, and the clamping column 64 moves upward on the clamping groove 65 along the inclined groove on the clamping groove 65, and the clamping column 64 drives the first connecting rod 8 and its parts as well as the second connecting rod 62 and its parts to move upward, thereby making way for the irradiation position of the laser probe 7, so that the laser probe 7 can perform laser rust removal on the blocked part of the steel bar, thereby increasing the rust removal area of ​​the steel bar.

[0059] After completing the rust removal on one side of the steel bar, the operator turns off the electric rotating rod 6 and the laser probe 7, turns the steel bar over, and turns on the electric rotating rod 6 and the laser probe 7 again, so that the laser probe 7 cleans the other side of the steel bar. After the cleaning is completed, the operator turns off the electric rotating rod 6 and the laser probe 7 and retracts the telescopic end of the hydraulic push rod 2, so that the telescopic end of the hydraulic push rod 2 drives the connecting frame 3 to move upward and complete the reset operation, thereby ending the rust removal.

[0060] Rust removal of steel bars requires double-sided laser scanning. After completing single-sided rust removal, the laser needs to be turned over to better remove the rust on the steel bars.

[0061] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 13-Figure 15 As shown, it also includes: a second motor 70, fixedly connected to the bracket 1, the output shaft of the second motor 70 is fixedly connected to the first fan-shaped plate 71, and the first fan-shaped plate 71 is slidably connected to the first arc-shaped rack 72; a limiting shaft 74, rotatably connected to the bracket 1, a transmission shaft 75 is fixedly connected in the limiting shaft 74, a rotating gear 73 is fixedly connected to the transmission shaft 75, and the first arc-shaped rack 72 and the rotating gear 73 are transmission-connected; a plurality of pairs of flipping wheels 76, all of which are rotatably connected to the transmission shaft 75, the limiting shaft 74 is used to limit the flipping wheel 76, the flipping wheel 76 is fixedly connected to a clamping plate 77, and the clamping plate 77 is used to clamp and flip the steel bar; an adjusting component is arranged on the transmission shaft 75, and is used to adjust the angle of the clamping plate 77.

[0062] In the above scheme, a method of automatically flipping the steel bars is proposed to save manpower and improve the rust removal efficiency; the flip wheel 76 is provided with teeth, which can be gear-driven; the clamping plate 77 clamps the steel bars and drives the steel bars to flip 180 degrees to improve the rust removal quality; the limiting shaft 74 is provided with a groove for the clamping plate 77 to rotate 90°, which can limit the clamping plate 77 and drive the clamping plate 77 to rotate during the rotation process. In this embodiment, the number of lifting shells 4 is two, and they are respectively located on the front and rear sides of the bracket 1, and a laser probe 7 is also provided in the lifting shell 4 on the rear side (the laser probe 7 is used to process the turned steel bars), and an electric rotating rod 6 and a threaded transmission rod 601 are also provided in the lifting shell 4 on the rear side for driving the laser probe 7 to move (this structure is consistent with the structure in the above embodiment); the two clamping plates 77 on the same pair of flipping wheels 76 are symmetrically distributed, and a gap is left between two adjacent clamping plates 77 for clamping the steel bars.

[0063] like Figure 13-Figure 15 As shown, the adjustment component includes: a second sector plate 81, fixedly connected to the output shaft of the second motor 70, and a second arc rack 82 is slidably connected to the second sector plate 81; a planetary gear set 83, rotatably connected to the bracket 1, the second arc rack 82 is transmission-connected to the input wheel of the planetary gear set 83, and the rotating wheel of the planetary gear set 83 is rotatably connected to the bracket 1; a missing gear 84, fixedly connected to the output wheel of the planetary gear set 83; there are two flip shafts 85, both of which are rotatably connected to the limit shaft 74, and the two flip shafts 85 are respectively located at On both sides of the limit shaft 74, a rotating gear is provided at one end of the flip shaft 85 close to the missing gear 84. The rotating gear on the flip shaft 85 is transmission-connected with the missing gear 84. A plurality of adjusting gears 851 are fixedly connected to the flip shaft 85. The number of adjusting gears 851 on the same flip shaft 85 is consistent with the logarithm of the flip wheels 76. Two adjacent adjusting gears 851 on the two flip shafts 85 are respectively meshed with different flip wheels 76 in an adjacent pair on the transmission shaft 75. The two adjusting gears 851 are used to adjust the angle of the splint 77.

[0064] The above scheme proposes a method for adjusting the angle of the clamping plate, so that the laser rust removal and flipping processes are more closely connected, thereby improving work efficiency; the symmetry lines of the first sector plate 71 and the second sector plate 81 coincide with each other, and the curvature of the first sector plate 71 is smaller than that of the second sector plate 81, which is used to make the meshing time of the second arc-shaped rack 82 and the input wheel of the planetary gear set 83 greater than the meshing time of the first arc-shaped rack 72 and the rotating gear 73; in the initial state, the first arc-shaped rack 72 is not meshed with the rotating gear 73, and the second arc-shaped rack 82 is in contact with the input wheel of the planetary gear set 83 (such as Figure 1 As shown, that is, one row of clamping plates 77 is in a vertical state); Fig.13As shown, in this state, the second arc-shaped rack 82 is meshed with the input wheel of the planetary gear set 83, the first arc-shaped rack 72 is in contact with the rotating gear 73, and the two rows of clamping plates 77 are both in a horizontal state; the planetary gear set 83 and the missing gear 84 both penetrate the transmission shaft 75; when the steel bar is turned over, as shown in FIG. Fig.13 In the state shown, the missing gear 84 and the flip shafts 85 on both sides are out of transmission state.

[0065] When the steel bar is derusted, the steel bar is placed on the bracket 1. At this time, the clamping plate 77 on the upper side is in a vertical state (i.e., the initial position). After completing the single-side derusting operation, the operator starts the second motor 70. The output shaft of the second motor 70 drives the first sector plate 71 and the second sector plate 81 to rotate counterclockwise (in degrees). Figure 1 When the lower side of the second sector plate 81 contacts the second arc-shaped rack 82, the second sector plate 81 drives the second arc-shaped rack 82 to rotate counterclockwise. During the counterclockwise rotation of the second arc-shaped rack 82, the second arc-shaped rack 82 meshes with the input wheel of the planetary gear set 83 and drives the input wheel of the planetary gear set 83 to rotate clockwise. The output wheel of the planetary gear set 83 drives the missing gear 84 to rotate counterclockwise, and the missing gear 84 drives the transmission gear on the flip shaft 85 on the upper side of the limit shaft 74 to rotate clockwise (with the rotation direction of the second sector plate 81). Figure 1 For example, the upper flip shaft 85 is defined as the upper flip shaft 85, and the lower flip shaft 85 is defined as the lower flip shaft 85), so that the upper flip shaft 85 drives all the adjusting gears 851 on the upper flip shaft 85 to rotate, and the adjusting gear 851 drives the clamping plate 77 to rotate and clamp the steel bar through the adjacent flip wheel 76 (the state at this time is as follows Fig.13 shown).

[0066] When the adjusting gear 851 drives the adjacent clamping plate 77 to rotate and clamp the steel bar, the lower side of the first sector plate 71 contacts the first arc rack 72, and the first sector plate 71 drives the first arc rack 72 to rotate counterclockwise, and the first arc rack 72 meshes with the rotating gear 73. Under the action of the first arc rack 72 and the rotating gear 73, the rotating gear 73 rotates clockwise, and the rotating gear 73 drives the transmission shaft 75 to rotate clockwise, and the transmission shaft 75 drives the limiting shaft 74 to rotate clockwise, and the limiting shaft 74 drives the flipping wheel 76 to rotate clockwise, and the flipping wheel 76 drives the clamping plate 77 to rotate clockwise. Under the combined action of the counterclockwise rotation of the first arc rack 72 and the rotating gear 73 and the counterclockwise rotation of the second arc rack 82 and the input wheel of the planetary gear set 83, the clamping plate 77 clamps the steel bar and drives the steel bar to rotate clockwise. , so that the steel bar is flipped clockwise. During this process, the missing gear 84 is not meshed with the transmission gears on the upper and lower flip shafts 85. After the flipping is completed, the first arc rack 72 loses meshing with the rotating gear 73, but the second arc rack 82 is still in meshing with the input wheel of the planetary gear set 83. The output wheel of the planetary gear set 83 drives the missing gear 84 to rotate counterclockwise and drives the flip shaft 85 gear on the lower side of the limit shaft 74 to rotate clockwise. The flip shaft 85 on the lower side drives all the adjusting gears 851 thereon to rotate clockwise. The adjusting gears 851 respectively drive the adjacent clamping plates 77 to rotate through the flip wheel 76 and rotate the clamping plates 77 to a vertical state. Then the operator turns off the second motor 70 to complete the flip switching action. At this time, the operator starts the electric rotating rod 6 and the laser probe 7, and removes rust from the steel bar.

[0067] After the laser probe 7 has completed rust removal on the other side of the steel bar, when it is necessary to reset the turned steel bar, the operator turns off the electric rotating rod 6 and the laser probe 7, turns on the second motor 70, the second motor 70 reverses and drives the lower turning shaft 85 to rotate counterclockwise, the lower turning shaft 85 drives all the adjusting gears 851 thereon to rotate counterclockwise, all the adjusting gears 851 on the lower turning shaft 85 respectively rotate the adjacent clamping plates 77 and clamp the steel bar, the second motor 70 reverses and drives the first sector plate 71 and the second sector plate 81 to rotate clockwise After the turning is completed, the upper turning shaft 85 drives all the adjusting gears 851 thereon to rotate counterclockwise, and all the adjusting gears 851 on the upper turning shaft 85 respectively rotate the adjacent clamping plates 77 to a vertical state, so that the clamping plates 77 will not block the steel bars. At this time, the operator turns off the second motor 70 to complete the entire resetting operation. After that, the operator collects the steel bars that have been derusted, and places another bundle of steel bars to be derusted on the bracket 1, and continues to repeat the above operations to remove the rust.
