[0002] Road surface roughening refers to the process of creating grooves and textures on concrete pavement during its initial setting using a roughening device. The resulting texture increases the friction between the concrete pavement and tires, reducing the risk of slippage. Furthermore, the grooves in the roughening pattern help to quickly drain rainwater, minimizing the water film effect.

[0003] Before the texturing process begins, the texturing brush needs to be lowered to insert into the partially set concrete pavement. After the texturing is complete, the brush needs to be raised to prevent damage during movement. Currently, adjusting the height of the texturing brush requires manual rotation of the screw rod by the operator. Because the truss supporting the brush is heavy, this requires significant manpower and is slow, impacting construction efficiency. Utility Model Content

When the device needs to move, the operator operates one of the clutch components, connecting the second output shaft of the power mechanism to the second intermediate shaft, which then drives the vehicle to move. When the road surface texturing device is in the texturing position and performing road surface texturing work, the operator operates one of the clutch components, connecting the first output shaft of the power mechanism to the first intermediate shaft, which then drives the lifting mechanism mounted on the first frame to operate.

[0025] like Figure 1As shown in the figure, this application embodiment provides a road surface roughening device, which includes two traveling vehicles 100, two power mechanisms 200, a first frame 300, a second frame 400, two lifting mechanisms 500, a linear motion mechanism 600, and a roughening brush 700.

[0026] Two traveling vehicles 100 are spaced apart for traveling on the ground and carrying other structures. When the road surface roughening device is performing roughening operations, the two traveling vehicles 100 are located on opposite sides of the road surface.

[0027] Two power mechanisms 200 are respectively mounted on two traveling vehicles 100. Each power mechanism 200 includes an actuator 210, a first intermediate shaft 220, a second intermediate shaft 230, and two clutch assemblies 240. The actuator 210 is connected to the traveling vehicle 100 and has a first output shaft 2121 and a second output shaft 2122. The first intermediate shaft 220 and the first output shaft 2121 are coaxially aligned, as are the second intermediate shaft 230 and the second output shaft 2122. The two clutch assemblies 240 are respectively connected to the first intermediate shaft 220 and the first output shaft 2121, as well as to the second intermediate shaft 230 and the second output shaft 2122. The two clutch assemblies 240 are used to control the connection and disconnection of the first output shaft 2121 with the first intermediate shaft 220, and the connection and disconnection of the second output shaft 2122 with the second intermediate shaft 2122.

[0028] The bottom of the first frame 300 is connected to two traveling vehicles 100, and the second frame 400 is located below the first frame 300. During the surface roughening operation of this road surface roughening device, both the first frame 300 and the second frame 400 are located above the road surface. The first frame 300 provides a mounting base for the two lifting mechanisms 500 and supports the second frame 400. The second frame 400 provides a mounting base for the linear motion mechanism 600.

[0029] Both lifting mechanisms 500 are mounted on the top surface of the first frame 300, and the output ends of both lifting mechanisms 500 are connected to the second frame 400. The input shaft of each lifting mechanism 500 is drivenly connected to the corresponding first intermediate shaft 220. When the first intermediate shaft 220 is connected to the first output shaft 2121, the power of the first output shaft 2121 is transmitted to the lifting mechanism 500 through the first intermediate shaft 220, thereby driving the second frame 400 to move in the height direction.

[0030] A linear motion mechanism 600 is mounted on the bottom of the second frame 400, and the moving end of the linear motion mechanism 600 is configured to move along a direction perpendicular to the travel direction of the two traveling vehicles 100. For example, Figure 6 The linear motion mechanism 600 shown is a lead screw and nut mechanism.

[0031] The textured brush 700 is connected to the moving end of the linear motion mechanism 600. When the linear motion mechanism 600 drives the textured brush 700 to move, the textured brush 700 can draw grooves on the road surface to form a textured surface.

[0032] When the road surface roughening device needs to move, the operator operates one of the clutch components 240, connecting the second output shaft 2122 of the power mechanism 200 with the second intermediate shaft 230, which in turn drives the traveling vehicle 100 to move. When the road surface roughening device is in the roughening position and performing road surface roughening work, the operator operates one of the clutch components 240, connecting the first output shaft 2121 of the power mechanism 200 with the first intermediate shaft 220, which in turn drives the lifting mechanism 500 mounted on the first frame 300 to operate. The lifting mechanism 500 drives the second frame 400 to move in the height direction, allowing the roughening brush 700 to extend into the initial setting area. On a concrete road surface, a linear motion mechanism 600 drives a textured brush 700 to move perpendicular to the direction of travel of the vehicle 100, creating grooves and textures on the road surface. After the road surface textured device completes one textured operation, the operator operates one of the clutch components 240, connecting the first output shaft 2121 of the power mechanism 200 with the first intermediate shaft 220. The first intermediate shaft 220 then drives the lifting mechanism 500 mounted on the first frame 300 to operate. The lifting mechanism 500 raises the second frame 400, causing the textured brush 700 to rise and detach from the road surface, thus preventing the textured brush 700 from creating grooves in the wrong position and from being bumped by obstacles on the road surface. Therefore, the road surface roughening device can switch the power transmission path of the power mechanism 200 through two clutch components 240, so that the power mechanism 200 can drive the traveling vehicle 100 to move and drive the lifting mechanism 500 to drive the roughening brush 700 installed on the second frame 400 to move in the height direction, saving manpower, reducing the time for adjusting the height of the roughening brush 700, and thus improving the efficiency of road surface construction.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the clutch assembly 240 includes a mounting plate 241, two clutches 242, and two shift forks 243. The mounting plate 241 is connected to the vehicle 100 and has a first elongated hole extending axially along the first output shaft 2121 and a second elongated hole extending axially along the second output shaft 2122. The two shift forks 243 are respectively connected to the two clutches 242 and pass through the first and second elongated holes respectively, and are configured to actuate the two clutches 242 to control the on / off state of the two clutches 242.

[0034] When it is necessary to connect the first output shaft 2121 to the first intermediate shaft 220, the operator operates the shift fork 243, causing the shift fork 243 to move within the first elongated hole and engage the corresponding clutch 242. When it is necessary to disconnect the first output shaft 2121 from the first intermediate shaft 220, the operator operates the shift fork 243 in the opposite direction, causing the shift fork 243 to move in the opposite direction within the first elongated hole and engage the corresponding clutch 242, disengaging the clutch 242. The operation process is the same when it is necessary to control the connection and disconnection of the second output shaft 2122 and the second intermediate shaft 230.

[0035] like Figure 4 As shown, the clutch 242 includes a first half-clutch 2421 and a second half-clutch 2422. The end face of the first half-clutch 2421 is provided with a plurality of first clutch teeth. The end face of the second half-clutch 2422 is provided with a plurality of second clutch teeth capable of engaging the gaps of the plurality of first clutch teeth. The side of the second half-clutch 2422 is provided with an annular groove for accommodating a shift fork 243, and the second half-clutch 2422 is provided with a splined hole. Both the first intermediate shaft 220 and the second intermediate shaft 230 are provided with external splines adapted to the splined hole.

[0036] When clutch 242 needs to be engaged, the second half-clutch 2422 on the first intermediate shaft 220 or the second intermediate shaft 230 is controlled to slide, so that the multiple second clutch teeth of the second half-clutch 2422 are engaged in the gaps of the multiple first clutch teeth of the first half-clutch 2421. The first half-clutch 2421 transmits the power of the first output shaft 2121 or the second output shaft 2122 to the second half-clutch 2422, and then the second half-clutch 2422 drives the first intermediate shaft 220 or the second intermediate shaft 230 to rotate.

[0037] Continue to refer to Figure 2 and Figure 3 The clutch assembly 240 also includes a guide seat 244, a guide rod 245, and a connecting block 246. The connecting block 246 is connected to the shift fork 243 and is used to move the shift fork 243. The guide seat 244 is mounted on the mounting plate 241. The guide rod 245 is located within the guide seat 244, and one end of the guide rod 245 is connected to the connecting block 246. The guide rod 245 and the guide seat 244 are used to guide the movement direction of the connecting block 246, thereby enabling the shift fork 243 to smoothly push the second half-clutch 2422 to move on the first intermediate shaft 220 or the second intermediate shaft 230.

[0038] When the shift fork 243 needs to be operated, the connecting block 246 slides along the first elongated hole and the second elongated hole, and the guide rod 245 slides in the guide seat 244 to guide the movement direction of the connecting block 246. Then the connecting block 246 drives the shift fork 243 to push the second half clutch 2422 to move.

[0039] like Figure 5 As shown, in some embodiments of this application, the lifting mechanism 500 includes a commutator 510 and two screw jacks 520. The two screw jacks 520 are mounted on the top of the first frame 300, and the nuts of the two screw jacks 520 are connected to the second frame 400. The commutator 510 is located between the two screw jacks 520, and the two output shafts of the commutator 510 are respectively connected to the input shafts of the two screw jacks 520. The input shafts of the commutator 510 are drive-connected to the first intermediate shaft 220.

[0040] For example, both the input shaft of the commutator 510 and the first intermediate shaft 220 are equipped with pulleys, and a belt is wound around the two pulleys. The power of the first intermediate shaft 220 is transmitted to the input shaft of the commutator 510 through the belt.

[0041] When it is necessary to adjust the height of the brush 700, the clutch 242 between the first output shaft 2121 and the first intermediate shaft 220 is engaged. At this time, the first intermediate shaft 220 rotates and drives the input shaft of the commutator 510. The nuts of the two screw jacks 520 drive the second frame 400 to move in the height direction, and the brush 700 moves with the second frame 400.

[0042] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the vehicle 100 includes a frame 110, two supports 120, two axles 130, and wheels 140 mounted at both ends of each axle 130. The bottom of the first frame 300 is fixedly connected to the frame 110. The two axles 130 are arranged in parallel and rotatably mounted on the supports 120, with one axle 130 being drive-connected to a second intermediate shaft 230. After the clutch 242 between the second intermediate shaft 230 and the second output shaft 2122 is engaged, the second intermediate shaft 230 drives one of the axles 130 to rotate, thereby causing the wheels 140 mounted at both ends of the axle 130 to rotate, allowing the entire road surface roughening device to move on the ground. The two supports 120 are fixedly connected to the frame 110 and are used to support the first intermediate shaft 220 and the second intermediate shaft 230, respectively. For example, bearing seats are installed on two brackets 120, and bearings are installed on both the first intermediate shaft 220 and the second intermediate shaft 230. The two brackets 120 support the first intermediate shaft 220 and the second intermediate shaft 230 respectively through the bearing seats and the bearings.

[0043] Furthermore, the two axles 130 are connected by a drive mechanism. When the power mechanism 200 drives one axle 130 to rotate, the other axle 130 rotates synchronously, making the road surface roughening device more stable when moving. For example, each axle 130 is equipped with a pulley, and a belt is wound around the two pulleys.

[0044] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the actuator 210 includes a motor 211 and a reducer 212. The reducer 212 is fixedly connected to the vehicle 100, and the reducer 212 has a first output shaft 2121 and a second output shaft 2122. The motor 211 is fixedly connected to the reducer 212, and the shaft of the motor 211 is connected to the input shaft of the reducer 212.

[0045] When the actuator 210 is working, the shaft of the motor 211 rotates and drives the input shaft of the reducer 212 to rotate. The first output shaft 2121 and the second output shaft 2122 of the reducer 212 rotate simultaneously to output power. The reducer 212 can reduce the speed and increase the torque.

[0046] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, please refer to each other. Each embodiment focuses on describing the differences from other embodiments.
