Description
Technical Field
[0001] This utility model relates to the field of road construction technology, specifically to a roughening device for concrete pavement. Background Technology
[0002] Roughening, also known as concrete roughening or concrete scrambling, is a technique that uses tools to create a rough texture on the surface of concrete. This method is simple to apply, relatively inexpensive, and enhances the bond between new and old concrete layers, improving the overall stability and skid resistance of the pavement. Roughening is particularly effective in repairing older pavements, significantly improving the adhesion of new layers. Furthermore, roughening maintains good performance even during winter construction.
[0003] Currently, in the existing equipment, even after the concrete is leveled, unevenness still occurs during the roughening process. This results in the roughening depth being sometimes shallow and sometimes deep, affecting the roughening effect and easily clogging the roughened parts. Consequently, the roughening effect is reduced, and practicality is diminished. Summary of the Invention
[0004] The problem this invention aims to solve is to provide a special roughening device for concrete pavements, overcoming the shortcomings of existing technologies.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a special roughening device for concrete pavement, comprising a moving body and a roughening unit, wherein both ends of the moving body have roller units;
[0006] The movable body includes a mounting frame and a transmission mechanism fixed within the mounting frame. The transmission mechanism includes two conveyor wheels located at both ends of the mounting frame. One end of the transmission shaft at the center of one of the conveyor wheels is rotatably connected to the mounting frame, and the other end is connected to a second motor fixed on the mounting frame. The fixed shaft at the center of the other conveyor wheel is connected to the mounting frame. A conveyor belt is wound between the two conveyor wheels.
[0007] The texturing unit includes a conveyor plate, a buckle plate, and a texturing component. The top of the conveyor plate is connected to the buckle plate, and the conveyor plate is fixed to the conveyor belt by the buckle plate. The side of the conveyor plate has a lifting groove, which is connected to the lower end face of the conveyor plate. A gear is located in the lifting groove, and the transmission rod at the center of the gear is rotatably connected to a fixed plate on the mounting frame. The top of the texturing component has a lifting plate with teeth on its surface. The upper end of the lifting plate extends from the lifting opening into the lifting groove and meshes with the gear.
[0008] Optionally, the end of the transmission rod is connected to a friction rod, and the fixed plate has a plurality of friction plates evenly distributed around the friction rod in the circumference, the friction plates being in contact with the surface of the friction rod.
[0009] Optionally, a drive column is sleeved on the transmission rod, and the surface of the drive column is provided with textures to increase friction.
[0010] Optionally, the mounting frame has two parallel and spaced limiting rods, and the conveying plate has limiting holes that correspond one-to-one with the limiting rods for the limiting rods to pass through. The conveying plate is slidably connected to the limiting rods.
[0011] Optionally, a leveling unit is also included, which includes a transmission plate, a lifting plate, and a V-shaped plate. The transmission plate is fixed to the side of the roughened part, and a slider is provided on the front side of the transmission plate. The lifting plate has a sliding groove adapted to the slider, and the slider can slide along the length direction of the lifting plate in the sliding groove. The V-shaped plate is fixed in the middle of the lifting plate. The mounting frame has two longitudinal limiting grooves arranged opposite to each other, and the two ends of the lifting plate are slidably installed in the limiting grooves.
[0012] Optionally, the roller unit includes three pulleys rotatably connected to the mounting frame. The three pulleys are arranged in a triangular pattern with one pulley on top and two on the bottom. A transmission belt is wound around the three pulleys. The transmission shaft at the center of the upper pulley is connected to the first motor. The transmission shafts at the centers of the two lower pulleys are respectively connected to the central shaft of one of the rollers. One end of the central shaft is rotatably connected to the mounting frame.
[0013] The advantages and positive effects of this utility model are as follows: The textured surface equipment for concrete pavement disclosed in this utility model, through the pushing of the V-shaped plate, flattens the upper surface of the concrete block, avoiding unevenness that could result in varying textured depths, thus improving the textured effect. It also removes impurities and larger objects from the upper surface of the concrete block, while preventing clogging of the textured parts, thereby enhancing the textured effect and practicality. The lifting plate allows for easy operation of the textured parts, enabling textured work on concrete blocks of different thicknesses. The inner surfaces of multiple friction pads increase the friction against the outer surface of the friction rod, effectively preventing the textured parts from moving upwards arbitrarily. The roller unit allows operators to adjust the direction using handles on both sides of the moving body, effectively eliminating the need for manual labor to move the textured device, reducing physical exertion, and accelerating the work process.

[0023] like Figure 1 As shown, this utility model provides a special roughening device for concrete pavement, including a moving body 1, a roughening unit 4 and a flattening unit 5, with roller units at both ends of the moving body 1.
[0024] The movable body 1 includes a mounting frame and a transmission mechanism fixed within the mounting frame, such as... Figure 3 , Figure 5 As shown, the transmission mechanism includes a first conveyor wheel 43 and a second conveyor wheel 45 located at both ends of the mounting frame, and a second motor 41 fixed on the mounting frame. The second motor 41 is connected to a fourth transmission shaft 42 at the center of the first conveyor wheel 43. One end of the fourth transmission shaft 42 passes through a transmission hole 421 opened on one side of the mounting frame. One end of the transmission hole 421 communicates with the inner wall of the conveying port 12, and the other end of the fourth transmission shaft 42 is rotatably engaged with a rotation hole opened on the inner wall of the conveying port 12. The first conveyor wheel 43 drives the second conveyor wheel 45 through a conveyor belt 44. A fixed shaft 451 is connected inside the second conveyor wheel 45. When the second motor 41 is started, it drives the fourth transmission shaft 42 to rotate in the transmission hole 421. The fourth transmission shaft 42 drives the first conveyor wheel 43 to rotate clockwise, and the conveyor belt 44 is driven by the force to rotate the second conveyor wheel 45 clockwise.
[0025] like Figure 4 , Figure 6As shown, the texturing unit 4 includes a conveyor plate 47, a buckle plate 46, and a texturing component 482. The top of the conveyor plate 47 is connected to the buckle plate 46, and the conveyor plate 47 is fixed to the conveyor belt 44 by the buckle plate 46. The conveyor belt 44 moves to one side, causing the buckle plate 46 and the conveyor plate 47 to move to one side, which can realize the back-and-forth texturing work. The side of the conveyor plate 47 has a lifting groove 471, which is connected to the lower end face of the conveyor plate 47. The lifting groove 471 has a gear 49 inside, and the transmission rod 491 at the center of the gear 49 is rotatably connected to the fixing plate 494 on the mounting frame. The top of the texturing component 482 has a lifting plate 48, and the surface of the lifting plate 48 has teeth 481. The upper end of the lifting plate 48 extends from the lifting port 472 into the lifting groove 471 and meshes with the gear 49. A friction rod 493 is connected to the end of the transmission rod 491. A plurality of friction plates 495 are evenly distributed around the friction rod 493 on the fixed plate 494, and the friction plates 495 are in contact with the surface of the friction rod 493. A drive column 492 is sleeved on the transmission rod 491, and the surface of the drive column 492 is textured to increase friction. By manually rotating the drive column 492 clockwise, the friction rod 493 rotates within the through hole of the fixed plate 494. The transmission rod 491 is subjected to force, causing the gear 49 at one end to mesh clockwise with the teeth 481. The teeth 481 are subjected to force, causing the lifting plate 48 to slide downwards into the lifting groove 471. The lifting plate 48 is subjected to force, which moves the brushed part 482 downwards. After the brushed part 482 descends to a suitable position, the rotation of the drive column 492 stops, thereby achieving the adjustment of the brushed part 482. In the rotating drive column 492, one end of the friction rod 493 rubs against the inner surface of multiple friction plates 495. After the rotating drive column 492 stops, the inner surface of the multiple friction plates 495 increases the friction force on the outer side of the friction rod 493, effectively preventing the roughened part 482 from moving upward at will.
[0026] The mounting frame has two parallel and spaced limiting rods 474. The conveyor plate 47 has limiting holes 473 that correspond one-to-one with the limiting rods 474, through which the limiting rods 474 pass. The conveyor plate 47 is slidably connected to the limiting rods 474. When the conveyor belt 44 moves to one side, it drives the buckle plate 46 and the conveyor plate 47 to move to one side. At the same time, the conveyor plate 47 slides to one side outside the limiting rods 474 through the limiting holes 473 on both sides, effectively ensuring that the roughened part 482 moves in a straight line.
[0027] like Figure 5As shown, the flattening unit 5 includes a transmission plate 51, a lifting plate 52, and a V-shaped plate 54. The transmission plate 51 is fixed to the side of the roughened part 482. The front side of the transmission plate 51 has a slider. The lifting plate 52 has a sliding groove 521 that matches the slider. The slider can slide in the sliding groove 521 along the length of the lifting plate 52. The V-shaped plate 54 is fixed in the middle of the lifting plate 52. The mounting frame has two longitudinal limiting grooves 53 that are arranged opposite to each other. The two ends of the lifting plate 52 are slidably installed in the limiting grooves 53. During the continued pushing process, the concrete is guided to the center using the inner surface of the V-shaped plate 54. This also fills in the gaps on the upper surface of the lower concrete block 6, allowing the upper surface of the concrete block 6 to be leveled. This facilitates the leveling of the upper surface of the concrete block 6 through the pushing of the V-shaped plate 54, avoiding unevenness that could result in varying depths of roughening, thus improving the roughening effect. It also removes impurities and larger objects from the upper surface of the concrete block 6, while preventing blockage of the roughening components, thereby enhancing the roughening effect and improving practicality.
[0028] The roller unit consists of a first drive mechanism 2 and a second drive mechanism 3 located on one side of the moving body 1. The first drive mechanism 2 and the second drive mechanism 3 have identical structures. Figure 2 As shown, the first drive unit 2 includes a first motor 21 mounted on a mounting frame. The output end of the first motor 21 is connected to a first rotating shaft 22. A first pulley 23 is sleeved on the outer side of one end of the first rotating shaft 22. The first pulley 23 is connected to a second pulley 25 and a third pulley 26 via a transmission belt 24. A second rotating shaft 251 is sleeved inside the second pulley 25. One end of the second rotating shaft 251 is rotatably fitted in a first through hole on the first rotating shell 11 on the mounting frame, and a first roller 252 is sleeved on one end of the second rotating shaft 251. The first roller 252 is located inside the first rotating shell 11. A third rotating shaft 262 is sleeved inside the third pulley 26. One end of the third rotating shaft 262 is rotatably fitted in a second through hole on the second rotating shell 111. A second roller 263 is sleeved on one end of the third rotating shaft 262. The second roller 263 is located inside the second rotating shell 111 on the mounting frame. The first rotating shell 11 and the second rotating shell 111 are located on the lower sides of the width surface of the moving body 1. The first motor 21 is started, driving the first rotating shaft 22 clockwise to drive the first pulley 23. The transmission belt 24 is force-driven to the second pulley 25 and the third pulley 26. The second pulley 25 is force-driven through the second rotating shaft 251 to drive the first roller 252 to roll clockwise. The third pulley 26 is force-driven through the third rotating shaft 262 to drive the first roller to roll clockwise. This causes the first roller 252 and the second roller 262 to move to one side at the same time. During the movement to one side, the direction can be adjusted using the handles on both sides of the moving body 1. This allows workers to move the roughening device without manual labor, reducing physical exertion and speeding up the work process.
[0029] The above-mentioned concrete pavement roughening equipment is used as follows: First, the moving body 1 is moved to both sides of the concrete block 6 via two first rollers 252 and two second rollers 262. After moving to the appropriate position, the position of the lifting plate 48 is adjusted. By manually rotating the drive column 492 clockwise, the friction rod 493 is rotated. The gear 49 at one end of the transmission rod 491 is subjected to force and meshes clockwise with the teeth 481. The teeth 481 are subjected to force and drive the lifting plate 48 to slide downward into the lifting groove 471. The plate 48 is driven downward by the force to the roughening component 482. After the roughening component 482 descends to the appropriate position, the rotating drive column 49 stops rotating. In the rotating drive column 49, one end of the friction rod 493 rubs against the inner surface of multiple friction soft plates 495. At the same time, the transmission plate 51 is driven by the downward force of the roughening component 482, causing the lifting plate 52 to slide downward into the interior of the limiting groove 53. The lifting plate 52 also drives the V-shaped plate 54 to press downward against the upper end surface of the concrete block 6. At this time, the roughening component 482 has been adjusted to the appropriate position.
[0030] After the drive column 492 stops rotating, the second motor 41 is started to drive the first conveyor wheel 43 to rotate clockwise. The conveyor belt 44 is driven by the second conveyor wheel 45 to rotate clockwise. The conveyor belt 44 drives the buckle plate 46 and the conveyor plate 47 to move to one side. At the same time, the conveyor plate 47 slides to one side on the outside of the limit rod 474 through the limit holes 473 on both sides. As the conveyor plate 47 moves, it drives the lifting plate 48 and the roughening part 482 to move to one side. The transmission plate 51 is driven to slide to one side inside the sliding groove 521. After gradually roughening back and forth, the roughening work is completed.
[0031] After the roughening process, when the position needs to be adjusted, first stop the second motor 41 and start the first motor 21 to drive the first pulley 23 clockwise. The transmission belt 24 is force-driven to the second pulley 25 and the third pulley 26. The second pulley 25 is force-driven to the first roller 252 to roll clockwise through the second rotating shaft 251. The third pulley 26 is force-driven to the first roller to roll clockwise through the third rotating shaft 262, so that the first roller 252 and the second roller 262 move to one side at the same time. During the movement to one side, the direction can be adjusted using the handles on both sides of the moving body 1.
[0032] As the moving body 1 moves to one side, it drives the V-shaped plate 54 to move to one side. Through the pre-adjusted position of the V-shaped plate 54, it pushes the concrete at the high point of the upper surface of the concrete block 6. As it continues to push, the pushed concrete is concentrated in the middle by the guide of the inner surface of the V-shaped plate 54. It can also fill the gaps on the upper surface of the concrete block 6, making the upper surface of the concrete block 6 flat. It also removes impurities or large objects from the upper surface of the concrete block 6. Each time the moving body 1 moves, the inner surface of the V-shaped plate 54 should be checked for impurities or large objects. Sometimes, timely cleaning is sufficient. This effectively makes the roughening part 482 perform a better roughening effect. After the moving body 1 moves, the second motor 41 is started to perform the back-and-forth roughening work.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
