Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a concrete roughening device. Background Technology

[0002] Cement concrete pavement is smoother than asphalt pavement, with a low surface friction coefficient and poor anti-skid performance. Rain and snow can easily affect driving safety. Therefore, the cement concrete surface of the road needs to be roughened and grooved. Roughening can increase the friction between the tire and the road surface and improve the anti-skid performance of the road surface.

[0003] Most current texturing tools produce grooves at fixed intervals, making it impossible to adjust the intervals according to the specific conditions on site. Therefore, this solution provides a concrete texturing tool. Utility Model Content

[0004] The purpose of this invention is to provide a concrete roughening tool that is easy to operate and allows for adjustment of the groove spacing.

[0005] This utility model is achieved through the following measures:

[0006] A concrete roughening device, characterized in that it includes a roughening mechanism, the roughening mechanism including a support frame, a round shaft disposed within the support frame, an external thread disposed on the periphery near one end of the round shaft, a matching nut disposed on the external thread of the round shaft, a sleeve disposed on the side of the nut facing the other end of the round shaft, the sleeve being sleeved around the round shaft, a plurality of rings slidably disposed on the periphery of the round shaft between the other end of the round shaft and the sleeve, each ring being provided with a steel wire for pulling out grooves, a plurality of springs being sleeved around the round shaft, the springs being disposed between two adjacent rings, the plurality of springs being of the same specification, the sleeve being moved by rotating the nut, the sleeve acting on the adjacent rings, and then the position of the plurality of rings being adjusted by the transmission action of the springs, since the plurality of springs are of the same specification, the compression of all springs is basically the same, thus making the spacing between the plurality of steel wires basically the same, thereby achieving the adjustment of the spacing between the steel wires by the extension and contraction of the springs.

[0007] The specific features of this utility model also include:

[0008] One end of the sleeve is rotatably mounted on the nut, and the other end of the sleeve is fixed to the ring on the side closest to it.

[0009] The two ends of the spring are respectively fixed on the corresponding rings. When the nut is rotated outward, the spacing of the steel wires can be adjusted by stretching the spring. When the nut is rotated inward, the spacing of the steel wires can be adjusted by compressing the spring.

[0010] The circular shaft is provided with a long sliding groove, and the circular ring is provided with a limiting block that cooperates with the long sliding groove. The limiting block is located in the long sliding groove and can prevent the circular ring from rotating, thereby ensuring that the steel wire is pulled out of the groove smoothly.

[0011] The texturing mechanism has a symmetrical left and right frame on each side. Each frame includes a base plate with a pair of electrically operated telescopic rods. A top plate is located at the top of each telescopic rod, and support plates are located on both sides of the top plate. A pair of guide rails are positioned between the left and right frames, with each end of the guide rail fixed to a corresponding pair of support plates on either side. A support frame is slidably positioned around the guide rails on both sides. The distance between the lower end of the steel wire and the cement surface can be adjusted using the electrically operated telescopic rods, further adjusting the groove depth. The groove is then pulled out by sliding the support frame along the guide rails. Alternatively, the guide rails can be steel wire ropes, which can be straightened by fixing the left and right frames.

[0012] Both sides of the top plate are provided with pulleys. Both sides of the support frame are provided with fixing plate one and fixing plate two. The fixing plate one on both sides is corresponding and is provided with through hole one. A belt is provided through the through hole one on both sides. The two ends of the belt are respectively wrapped around the pulley on the corresponding side and are respectively set on the fixing plate two on both sides.

[0013] A motor is installed on the top plate of the left frame, and the corresponding pulley is connected to the output shaft of the motor. The motor drives the pulley to rotate, which in turn drives the sliding of the grouting mechanism, thereby pulling out the groove. The forward and reverse rotation of the motor can change the movement direction of the grouting mechanism.

[0014] Both sides of the fixing plate 2 are provided with through holes 2, and both sides of the fixing plate 2 are provided with locking mechanisms on their opposite inner surfaces;

[0015] The locking mechanism includes a pair of rotating shafts disposed on the fixed plate 2. The pair of rotating shafts are respectively disposed on both sides of the through hole 2. Pads are disposed around the periphery of the rotating shafts. The pads on both sides are symmetrically arranged. The belt is provided with several slots that cooperate with the pads. The pads are locked in the slots, thereby achieving the fixed locking of the belt. In use, the belt is first passed through the through hole 1 and wrapped around the pulleys on both sides. Then, the two ends of the belt are respectively passed through the through hole 2. The pads on both sides are pried outward by hand. Then, the corresponding ends of the belt are grasped and pulled. After tightening, the pads on both sides are released, so that the pads are locked in the corresponding slots, thereby tightening the belt.

[0016] A torsion spring is provided around the rotating shaft on both sides of the pawl. One end of the torsion spring is fixed to the pawl, and the other end of the torsion spring is fixed to the bracket on the corresponding side for mounting the rotating shaft.

[0017] The base plate is equipped with several casters, which allow the left and right frames to be moved.

[0018] The base plate is equipped with pins, which can be used to fix the left frame and the right frame to the ground.

[0019] The beneficial effects of this utility model are as follows: This solution has a simple structure and is easy to operate. By using several springs of the same specification, the groove spacing can be adjusted, which not only improves work efficiency, but also meets the needs of the project. Attached Figure Description

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] Example 1

[0029] See Figure 1 A concrete texturing device includes a texturing mechanism, which includes a support frame 2. A round shaft is disposed inside the support frame 2. An external thread is provided on the outer periphery near one end of the round shaft. A matching nut 14 is provided at the external thread of the round shaft. A sleeve 15 is provided on the side of the nut 14 facing the other end of the round shaft. The sleeve 15 is sleeved around the outer periphery of the round shaft. Several rings 16 are slidably disposed on the outer periphery of the round shaft between the other end of the round shaft and the sleeve 15. Steel wires 1 for pulling out grooves are provided on the rings 16. Several springs 17 are sleeved around the outer periphery of the round shaft. The springs 17 are disposed between two adjacent rings 16. The several springs 17 are of the same specification. By rotating the nut 14, the sleeve 15 can be moved. The sleeve 15 acts on the adjacent rings 16. Then, through the transmission action of the springs 17, the position of the several rings 16 can be adjusted. Since the several springs 17 are of the same specification, the compression of all the springs 17 is basically the same, so the spacing between the several steel wires 1 is basically the same. Thus, the spacing between the steel wires 1 is adjusted by the extension and contraction of the springs 17.

[0030] Example 2

[0031] See Figures 1-3 A concrete texturing device includes a texturing mechanism, which includes a support frame 2. A round shaft is disposed inside the support frame 2. An external thread is provided on the outer periphery near one end of the round shaft. A matching nut 14 is provided at the external thread of the round shaft. A sleeve 15 is provided on the side of the nut 14 facing the other end of the round shaft. The sleeve 15 is sleeved around the outer periphery of the round shaft. Several rings 16 are slidably disposed on the outer periphery of the round shaft between the other end of the round shaft and the sleeve 15. Steel wires 1 for pulling out grooves are provided on the rings 16. Several springs 17 are sleeved around the outer periphery of the round shaft. The springs 17 are disposed between two adjacent rings 16. The several springs 17 are of the same specification. By rotating the nut 14, the sleeve 15 can be moved. The sleeve 15 acts on the adjacent rings 16. Then, through the transmission action of the springs 17, the position of the several rings 16 can be adjusted. Since the several springs 17 are of the same specification, the compression of all the springs 17 is basically the same, so the spacing between the several steel wires 1 is basically the same. Thus, the spacing between the steel wires 1 is adjusted by the extension and contraction of the springs 17.

[0032] One end of the sleeve 15 is rotatably mounted on the nut 14, and the other end of the sleeve 15 is fixed to the ring 16 near the side;

[0033] The two ends of the spring 17 are fixed on the corresponding rings 16. When the nut 14 is rotated outward, the spacing of the steel wires 1 can be adjusted by stretching the spring 17. When the nut 14 is rotated inward, the spacing of the steel wires 1 can be adjusted by compressing the spring 17.

[0034] The circular shaft is provided with a long sliding groove, and the circular ring 16 is provided with a limiting block that cooperates with the long sliding groove. The limiting block is set in the long sliding groove and can prevent the circular ring 16 from rotating, thereby ensuring that the steel wire 1 is pulled out of the groove smoothly.

[0035] The texturing mechanism has a symmetrical left and right frame on each side. Both the left and right frames include a base plate 7, on which a pair of electric telescopic rods 6 are mounted. A top plate 5 is mounted on the top of the pair of electric telescopic rods 6. Support plates are mounted on both sides of the top plate 5. A pair of guide rails 3 are mounted between the left and right frames. The two ends of the guide rails 3 are fixed to the corresponding pair of support plates on both sides. The support frame 2 is slidably mounted on the periphery of the guide rails 3 on both sides. The distance between the lower end of the steel wire 1 and the cement surface can be adjusted by the electric telescopic rods 6, and the groove depth can be further adjusted. Then, the groove is pulled out by sliding the support frame 2 along the guide rails 3. Alternatively, the guide rails 3 can be steel wire ropes, which can be straightened by fixing the left and right frames.

[0036] Both sides of the top plate 5 are equipped with pulleys 9. Both sides of the support frame 2 are equipped with fixing plate 10 and fixing plate 21. The two fixing plates 10 are corresponding and each has a through hole 1. A belt 4 is installed through the two through holes 1. The two ends of the belt 4 are respectively wrapped around the pulleys 9 on the corresponding sides and then installed on the two fixing plates 21.

[0037] A motor 8 is installed on the top plate 5 of the left frame, and the corresponding side pulley 9 is connected to the output shaft of the motor 8. The motor 8 drives the pulley 9 to rotate, which in turn drives the sliding of the roughening mechanism, thereby realizing the pulling out of the groove. The forward and reverse rotation of the motor 8 can change the movement direction of the roughening mechanism.

[0038] Both sides of the fixing plate 21 are provided with through holes 2, and both sides of the fixing plate 21 are provided with locking mechanisms on their opposite inner surfaces.

[0039] The locking mechanism includes a pair of rotating shafts mounted on the fixed plate 11. The pair of rotating shafts are respectively mounted on both sides of the through hole 2. Pads 12 are mounted around the rotating shafts. The pads 12 are symmetrically arranged on both sides. The belt 4 is provided with several slots 13 that cooperate with the pads 12. The pads 12 are locked in the slots 13, thereby achieving the fixed locking of the belt 4. In use, first pass the belt 4 through the through hole 1 and wrap it around the pulleys 9 on both sides. Then, let both ends of the belt 4 pass through the through hole 2. Use your hands to pry the pads 12 on both sides outward. Then, grab the corresponding ends of the belt 4 and pull hard. After tightening, release the pads 12 on both sides so that the pads 12 are locked in the corresponding slots 13, thereby tightening the belt 4.

[0040] Torsion springs are provided around the rotating shafts on both sides of the pawl 12. One end of the torsion spring is fixed to the pawl 12, and the other end of the torsion spring is fixed to the bracket on the corresponding side for mounting the rotating shaft.

[0041] The base plate 7 is equipped with several casters, which can be used to move the left and right frames.

[0042] The base plate 7 is equipped with pins, which can be used to fix the left and right frames to the ground.
