Detailed Implementation
[0015] The preferred embodiments of this utility model will be described below with reference to the accompanying drawings.
[0016] like Figures 1 to 6As shown, a concrete pavement roughening device is disclosed. The device includes a support frame, roughening components, and a drive mechanism. The support frame spans across the width of the concrete pavement, and the roughening components move smoothly using the support frame. The drive mechanism controls the reciprocating movement of the roughening components. The support frame can be disassembled into multiple components to reduce its footprint and volume, thus facilitating storage and transportation. The roughening components and drive mechanism can also be disassembled for easier storage and transportation.
[0017] The support frame includes uprights 1 and combined crossbeams 2. Uprights 1 are arranged side-by-side at intervals and connected, forming a portal frame mechanism in conjunction with the combined crossbeams 2. The combined crossbeams 2 and uprights 1 have a detachable connection structure. The combined crossbeams 2 can also be disassembled into multiple sections. Uprights 1 mainly include T-shaped frames 3 and full-brake casters 4. The full-brake casters 4 are universal casters with braking devices. Structurally, the T-shaped frames 3 include a rod-shaped transverse base and an H-shaped frame vertically fixed in the middle of the transverse base. The H-shaped frame forms a clamping space, facilitating the cooperation of other components. Multiple set screws 5 are longitudinally spaced on one side of the H-shaped frame, using the set screws 5 to laterally hold and clamp the clamping components. Two full-brake casters 4 are provided and fixedly installed at both ends of the transverse base, facilitating the movement of the entire portal frame along the length of the concrete pavement and making it easy for workers to push it forward. The combined crossbeams 2 include a crossbeam body 6 and positioning joints 7. The number of crossbeam bodies 6 is not less than two; the crossbeam body 6 is generally rectangular cylindrical and can be made of square tubing. The positioning joint 7 has a rectangular cylindrical cross-section and is adapted to the shape of the port of the crossbeam body 6. The positioning joint 7 is inserted between adjacent crossbeam bodies 6. The positioning joint 7 is fixedly connected to one crossbeam body 6, while the crossbeam body 6 not fixedly connected to the positioning joint 7 is fixedly provided with a protrusion 8. The protrusion 8 is square-shaped, and preferably two protrusions 8 are provided near the port. The positioning joint 7 is used to connect two crossbeam bodies 6 in series and ensure that they are straight and the edges are aligned. The protrusions 8 can be used to disengage adjacent crossbeam bodies 6 by striking with a hammer. The two ends of the combined crossbeam 2 are inserted into the clamping space formed by the H-shaped frame and abut against the transverse bar formed by the H-shaped frame. The H-shaped frame and the combined crossbeam 2 are fixed by lateral support of at least one set screw 5. Preferably, two set screws 5 are provided for support.
[0018] The texturing assembly includes a movable seat 9 and a texturing frame 10. The movable seat 9 includes a sleeve 11 and elastic tension wheels. The sleeve 11 is generally rectangular and fits onto the combined crossbeam 2, with a certain gap reserved between it and the upper and lower sides of the combined crossbeam 2, and sliding fit on the left and right sides. A hanging ring 35 is provided on the upper side of the sleeve 11. Four elastic tension wheels are provided on the upper and lower sides of the cylinder, arranged in a rectangular pattern on each side; this allows the sleeve 11 to move stably on the combined crossbeam 2. Structurally, the elastic tension wheel includes a guide shaft 12, a U-shaped frame 13 fixed to one end of the guide shaft 12, a roller 14 rotatably connected to the U-shaped frame 13, and a spring 15 fitted onto the guide shaft 12 and fixedly connected at both ends to the inner wall of the sleeve 11 and the U-shaped frame 13, respectively. The guide shaft 12 vertically penetrates the sleeve 11 and slides into it; the cross-section of the guide shaft 12 is oval, which allows for circumferential stopping with the sleeve 11. The protrusions 8 are located between the moving tracks of the rollers 14 to avoid interference. To achieve fine-tuning of the brush depth and allow the brush strip 21 to quickly detach from the road surface, adjusting blocks 16 are threaded onto guide shafts 12 located above and below the combined crossbeam 2. The adjusting blocks 16 are located outside the sleeve 11 and have control levers 17. Rotating the corresponding upper and lower control levers 17 controls the distance between the corresponding roller 14 and the inside of the sleeve 11, thus easily changing the force between the roller and the combined crossbeam 2 and achieving the longitudinal alignment of the sleeve 11 relative to the combined crossbeam 2. The brushing frame 10 includes a U-shaped plate 18, a screw 19, a cross plate 20, and a brush strip 21. U-shaped plate 18 is fixed to the lower side of sleeve 11; screw 19 is longitudinally arranged and passes through U-shaped plate 18, and also slides with U-shaped plate 18; horizontal plate 20 is fixed to the lower end of screw 19 to form a T-shaped structure; multiple brush strips 21 are fixed on horizontal plate 20. The overall structure consisting of screw 19, horizontal plate 20 and brush strips 21 is replaceable. For example, brush strips 21 can be replaced with steel bars or tungsten steel strips, or other existing scratching materials. Two nuts 22 are threaded on screw 19. The two nuts 22 are located on the upper and lower sides of U-shaped plate 18 and clamp the bottom wall of U-shaped plate 18, so that screw 19 is fixed relative to U-shaped plate 18. Loosening nuts 22 can adjust the longitudinal height of screw 19 relative to U-shaped plate 18. Tightening them again can adjust the scratching depth.
[0019] The drive mechanism includes a manual reel 23, a first pulley frame 24, and a second pulley frame 25. Two manual reels 23 are provided and spaced vertically apart. Each manual reel 23 includes a rotating shaft 26, side baffles 27, and a handwheel 28. The rotating shaft 26 is horizontally positioned and rotatably connected to two vertical rods formed by the H-shaped frame; two side baffles 27 are fixed to the rotating shaft 26 and spaced apart, located inside the clamping space formed by the H-shaped frame; the handwheel 28 is fixed to one end of the rotating shaft 26. Rotating the handwheel 28 drives the rotating shaft 26 to rotate, causing the rope wound on the rotating shaft 26 to be wound or unwound, thus controlling the operation of the manual reel 23. The handwheel 28 can also be replaced by a rod. The first pulley frame 24 is detachably connected to the movable base 9. The first pulley frame 24 includes a first base 29 and a first pulley 30. The first base 29 is generally slatted, with a hook 34 on one side. The hook 34 and the hanging ring 35 cooperate to detachably connect the first pulley frame 24 and the movable seat 9. Two first pulleys 30 are provided, fixed side-by-side at intervals on the other side of the first base 29. The second pulley frame 25 includes a second base 31 and a second pulley 32. The second base 31 is generally slatted. The second pulley frame 25 is clamped within the clamping space formed by the H-shaped frame. Two set screws 5 on the H-shaped frame hold the second pulley frame 25, fixing it relative to the H-shaped frame. For a more stable fixation, recessed grooves 33 are provided on both sides of the second pulley frame 25, allowing for sliding engagement with the H-shaped frame. This structure also makes the second pulley frame 25 detachable from the H-shaped frame. One second pulley 32 is provided and fixed to one side of the second base 31.
[0020] A pull rope is wound on one manual reel 23. One end of the pull rope is guided by the first pulley 30, then folded back and fixedly connected to the H-shaped frame. Another pull rope is wound on the other manual reel 23. One end of the other pull rope is guided in the opposite direction by the second pulley 32, then guided in the opposite direction by the first pulley 30, and finally connected and fixed to the second pulley frame 25. When the two manual reels 23 are rotated individually, the first pulley frame 24 can be moved laterally back and forth, which in turn causes the sleeve 11 to drive the brushing frame 10 to move back and forth.
[0021] The working process and principle of this utility model are as follows: First, assemble the entire device. Assemble the combined crossbeam 2 by connecting two crossbeam bodies 6 using positioning joints 7. During assembly, the protrusions 8 can be used to achieve efficient and rapid connection. Multiple crossbeam bodies 6 are then assembled to form the combined crossbeam 2. Next, sleeve 11 is fitted onto the combined crossbeam 2. Then, erect the upright frame 1, first placing the combined crossbeam 2 onto the H-frame to pre-form a portal structure. Then, adjust the spacing of the upright frames 1 based on the width of the concrete pavement. After the spacing is adjusted, tighten the set screw 5 to fix the combined crossbeam 2 relative to the upright frame 1. Connect the first pulley frame 24 to the sleeve 11 using the cooperation of hook 34 and hanging ring 35. Hook 34 can be a self-locking hook. Pull the second pulley frame 25 and rotate it onto the H-frame, fixing it by tightening the corresponding set screw 5. Control the manual reel 23 to rotate appropriately and pre-tighten the pull rope; at this point, the installation of the drive mechanism is complete. Finally, install the screw 19 and nut 22 onto the U-shaped plate 18, and make the brush strip 21 contact the ground.
[0022] When performing the roughening operation: Place the entire device on a concrete surface or a flat area on the outer side of the concrete surface. Initially adjust the combined crossbeam 2 so that it aligns with the width direction of the road surface, and lock the full-brake casters 4 to fix the position of the entire device. Operate the manual reel 23 to move the first pulley frame 24 to one side of the road surface. Then operate the control lever 17 to tighten the adjusting block 16, causing the corresponding roller 14 to move upward. At this time, the force of the four rollers 14 on the upper side of the combined crossbeam 2 is less than that on the lower side, causing the sleeve 11 to move downward relative to the combined crossbeam 2, thereby allowing the comb to be pressed into the concrete surface, achieving adjustment of the pressing depth; at the same time, record the position of the control lever 17 after rotation. Operate the manual reel 23 located at the top, keeping the manual reel 23 in an unrestrained state. When the reel rotates to retrieve the pull rope, under the action of the second pulley frame 25, the pull rope drives the first pulley frame 24 to move along the length direction of the combined crossbeam 2, and then drives the roughening frame 10 to move on the concrete surface through the moving seat 9 to achieve the roughening operation. After the surface roughening frame 10 is moved to the other side of the road, the full-brake casters 4 are unlocked, and the equipment is pushed forward to the designated position. Then, the full-brake casters 4 are locked. Next, the manual reel 23 below is operated, and the rope drives the first pulley frame 24 to move in the reset direction, thus achieving the roughening effect. If the roughening depth is not visually satisfactory during the roughening process, it can be adjusted using the control lever 17 to ensure the anti-slip effect. The manual reel 23 and the pulley utilize a labor-saving coordination method, which helps to reduce manual labor consumption. After the roughening operation is completed, the equipment can be disassembled and separated in reverse order of rotation, forming individual parts for storage or transportation.
