Description

Technical Field

[0001] The present invention relates to the technical field of road paving, and specifically provides an auxiliary paving device for curb stones in the green belt of urban roads. Background Art

[0002] Curb stones are the marker stones set between roads and other structures. Curb stones are generally required to be set between the green belts and roads, as well as between sidewalks and roads in urban roads. When paving curb stones, usually a trench for paving curb stones is dug in advance at the edge of the road, a layer of concrete mortar is evenly paved at the bottom of the trench, and then an excavator equipped with a curb stone clamp is used to pick up the curb stone and place it in the trench for paving.

[0003] There are also specific devices for implementing the paving operation of curb stones. For example, the Chinese invention patent with the publication number CN218492224U discloses a curb stone paving mechanism. The back of the buffer plate supports the curb stones transmitted from the rear. The buffer plate is turned downward to make the curb stones fall onto the guiding slope plate. The curb stones slide downward into the gap and stand upright on the ground in the Y direction, realizing the automatic paving of curb stones; the Chinese invention patent with the publication number CN115679777A discloses a curb stone paving device for highway construction. During use, the discharging mechanism can pick up the curb stones and place them at the designated positions. If the direction after falling is correct, there is no need for workers to manually straighten them, thus playing a role of simple operation and achieving the purpose of simple structure.

[0004] However, whether it is the above specific devices or the excavator with a clamp, the following problems still exist in the process of paving curb stones: 1. After the curb stone is placed in the trench, the newly placed curb stone cannot be accurately aligned with the paved curb stone. It is still necessary to manually assist in controlling the landing position, then unload the curb stone, adjust the alignment with the adjacent curb stones, and finally perform the pressing operation. The overall flexibility, convenience, and efficiency need to be improved; 2. When placing the curb stone, the distance between the curb stone and the road cannot be accurately controlled. Only the distance between the curb stone and the road can be roughly determined manually, which will affect the neatness of the curb stone paving. Summary of the Invention

[0017] Advantages of the present invention: 1. By the combined use of the positioning mechanism and the clamping mechanism, when laying the curbstone, the positioning mechanism moves along the edge of the road driven by the excavator. The positioning mechanism positions the laid curbstone. The clamping mechanism grabs the second curbstone driven by the mechanical arm of the excavator. The horizontal plate is made parallel to the U-shaped frame through the insertion and mating of the docking component and the alignment component. Then, the rotation angle of the turntable is adjusted by the third driving motor, so that the newly grabbed curbstone is parallel to the horizontal plate. Then, the mechanical arm drives the newly grabbed curbstone to move down to be flush with the laid curbstone. Finally, the left and right moving component drives the newly grabbed curbstone to move to the right, so that the newly grabbed curbstone is closely attached to the laid curbstone, ensuring that adjacent curbstones are aligned and closely attached to each other.

[0018] 2. The present invention positions the laid curbstone through the positioning mechanism. The U-shaped frame is rollingly clamped outside the laid curbstone through the clamping and guiding component and moves along the laid curbstone. At the same time, under the pulling of the elastic connection component, the first positioning wheel moves along the edge of the road, keeping a constant distance between the curbstone and the road, facilitating the positioning of the laid curbstone, improving the neatness of the curbstone laying. At the same time, by using the U-shaped frame as the positioning point for the subsequent curbstone laying, it is beneficial for the subsequent laid curbstone to be aligned with the previously laid curbstone.

[0031] To make the above objects, features, and advantages of the present invention more apparent and understandable, the following provides a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Please refer to Figure 1 、 Figure 2 and Figure 3 , an auxiliary paving device for the curbstone of the urban road green belt, which includes a positioning mechanism 1 and a clamping mechanism 2 arranged on the left side of the positioning mechanism 1. The positioning mechanism 1 includes a U-shaped frame 11, an elastic connection component 12 is installed on the top of the U-shaped frame 11, two groups of first positioning wheels 13 are symmetrically installed on the front and rear sides of the U-shaped frame 11, the number of the first positioning wheels 13 in each group is two, a distance adjustment component 14 for adjusting the first positioning wheels 13 back and forth is installed on the U-shaped frame 11, a positioning component 15 is installed on the top of the left end of the U-shaped frame 11, and a clamping guide component 16 is also installed on the U-shaped frame 11.

[0033] Please refer to Figure 1 、 Figure 5 and Figure 6 , the clamping mechanism 2 includes a top plate 21, a cross plate 22 is rotatably installed at the bottom of the top plate 21 through a first rotating shaft, a rotating component 23 for driving the cross plate 22 to rotate is installed on the top plate 21, and a docking component 24 that is inserted and matched with the positioning component 15 is fixedly connected to the bottom of the right end of the cross plate 22.

[0034] Please refer to Figure 1 、 Figure 5 and Figure 6 , a bottom plate 25 is installed at the bottom of the left end of the cross plate 22 in a left-right sliding manner, a left-right moving component 26 for driving the bottom plate 25 to move left and right is installed at the bottom of the cross plate 22, a turntable 27 is rotatably installed at the bottom of the bottom plate 25 through a second rotating shaft, a hydraulic clamping jaw 271 is fixedly connected to the bottom of the turntable 27, a third driving motor 28 for driving the turntable 27 to rotate is installed on the bottom plate 25, a locking component 29 for locking the turntable 27 is installed at the bottom of the rear side of the bottom plate 25, a double link connected to the robotic arm of the excavator 3 is installed on the top of the top plate 21, and the cross plate 22 is installed on the robotic arm of the excavator 3 through the double link.

[0035] Please refer to Figure 1 and Figure 2, the elastic connection component 12 includes a fixing plate 121 fixedly connected to the top of the positioning mechanism 1. A plurality of first guide rods 122 distributed in a rectangular shape are slidably inserted into the fixing plate 121 in the front-back direction. The rear ends of the plurality of first guide rods 122 are fixedly connected together to form a mounting plate 123. A plurality of tension springs 124 sleeved outside the corresponding first guide rods 122 are fixedly connected between the fixing plate 121 and the mounting plate 123. The mounting plate 123 is mounted on the push shovel oil cylinder on the chassis of the excavator 3.

[0036] By driving the mounting plate 123 to move up and down through the push shovel oil cylinder, it is convenient to lower the U-shaped frame 11 into the groove dug in advance at the edge of the road. When the excavator 3 moves along the road, the excavator 3 will drive the mounting plate 123 to move together. The first guide rods 122 can move on the fixing plate 121 to make up for the deviation that occurs during the movement of the excavator 3. The tension of the tension springs 124 is used to pull the U-shaped frame 11 to move in the direction close to the excavator 3, so that the positioning wheel one 13 at the rear side of the U-shaped frame 11 can always be in contact with the edge of the road, keeping a constant distance between the U-shaped frame 11 and the edge of the road, and thus making the laid curbstone keep the same distance from the edge of the road. It should be noted that the road in the present invention refers to the asphalt road surface or concrete road surface that has been laid and dried.

[0037] Please refer to Figure 2 and Figure 3 , the distance adjustment component 14 includes a central shaft 141 fixedly connected to the top of the U-shaped frame 11. A scissor frame 142 is rotatably mounted on the central shaft 141. Cross beams 143 are symmetrically arranged on the front and rear sides of the U-shaped frame 11. A first guide rail 144 is fixedly connected to the top of the cross beam 143. Four ends of the scissor frame 142 are all rotatably connected with first sliders 145. The two first sliders 145 on the same side of the U-shaped frame 11 are jointly slidably mounted in the corresponding first guide rail 144. A driving component 146 for driving the two scissor arms of the scissor frame 142 to rotate is mounted on the U-shaped frame 11. Vertical rods 131 are fixedly connected to the bottoms of the left and right ends of the cross beam 143. The positioning wheel one 13 is rotatably mounted at the bottom of the corresponding vertical rod 131. A positioning wheel two 17 is also rotatably mounted on the rear side of the vertical rod 131 at the rear side of the U-shaped frame 11.

[0038] Please refer to Figure 2 and Figure 3 , the driving component 146 includes an electric telescopic rod 1461 fixedly mounted on the top of the U-shaped frame 11. The left end of the telescopic shaft of the electric telescopic rod 1461 is fixedly connected with a push rod 1462. Round rods 1463 are rotatably connected to the bottoms of the front and rear ends of the push rod 1462. Chute grooves 1464 are opened at the tops of the right ends of the two scissor arms of the scissor frame 142. The round rods 1463 are slidably mounted inside the chute grooves 1464.

[0039] After placing the U-shaped frame 11 into the groove on the road edge, the push rod 1462 and the round rod 1463 are pushed to move leftward by the electric telescopic rod 1461. Then, the round rod 1463 pushes the two scissor arms of the scissor frame 142 to open outward. During the pushing process, the round rod 1463 will slide along the inside of the chute 1464. The opened scissor frame 142 pushes the first guide rail 144 and the cross beam 143 to move away from the U-shaped frame 11 through the first slider 145. During the process of the scissor frame 142 opening outward, the two first sliders 145 in the same first guide rail 144 will approach each other, and the two cross beams 143 move away from each other. Then, the cross beam 143 drives the first positioning wheel 13 to move, so that the rear first positioning wheel 13 abuts against the rear side wall of the groove (i.e., the side wall of the road), and at the same time, the second positioning wheel 17 rolls along the upper end surface of the road. By the above operations, the distance between the first positioning wheel 13 and the U-shaped frame 11 is adjusted, thereby adjusting the distance between the U-shaped frame 11 and the road, which is convenient for positioning the subsequent distance between the curbstone and the road.

[0040] Please refer to Figure 3 and Figure 4 As shown in FIGS. and, the clamping and guiding assembly 16 includes a plurality of first rollers 161 that are rotatably installed inside the front vertical section of the U-shaped frame 11 and are equally spaced left and right. A threaded rod 164 is threadedly connected to the rear vertical section of the U-shaped frame 11. The front end of the threaded rod 164 is rotatably connected to a movable plate 162 located inside the U-shaped frame 11. A plurality of second rollers 163 that are equally spaced left and right are rotatably installed on the front side of the movable plate 162. The rear side of the movable plate 162 is fixedly connected with second guide rods 165 that are symmetrically distributed left and right with respect to the threaded rod 164. The rear ends of the second guide rods 165 slide through to the rear side of the U-shaped frame 11.

[0041] After placing the first curbstone into the groove on the road edge, then the excavator 3 places the U-shaped frame 11 into the groove. When placing, the U-shaped frame 11 covers the outside of the curbstone, and the first rollers 161 and the second rollers 163 are distributed on the front and rear sides of the curbstone. Then, the threaded rod 164 is rotated to push the movable plate 162 to move forward. The second guide rods 165 play a guiding role for the movable plate 162 to prevent the movable plate 162 from rotating. After that, the movable plate 162 drives the second rollers 163 to move forward, so that the first rollers 161 and the second rollers 163 abut against the front and rear sides of the curbstone, preventing the U-shaped frame 11 from shifting from the curbstone and ensuring that the U-shaped frame 11 is parallel to the curbstone, thereby forming a positioning reference for the subsequent placement of the curbstone.

[0042] Please refer to Figure 2 and Figure 3, the alignment component 15 includes a support frame 151 fixedly connected to the top of the left end of the U-shaped frame 11. A central alignment ring 152 is fixedly installed on the top of the support frame 151. Positioning holes 153 are formed on the top of the support frame 151 and are symmetrically distributed before and after the central alignment ring 152.

[0043] Please refer to Figure 1 , Figure 5 and Figure 7 , the rotation component 23 includes a first driving motor 231 fixedly installed on the top of the top plate 21. The output shaft of the first driving motor 231 penetrates below the top plate 21 and drives the first rotating shaft to rotate through a first gear set. An arc-shaped groove 232 is formed on the top plate 21 to the left of the first rotating shaft. The center of the arc-shaped groove 232 coincides with the axis of the first rotating shaft. A connecting column 233 is rotatably connected to the top of the cross plate 22. The connecting column 233 is slidably installed inside the arc-shaped groove 232. The output shaft of the third driving motor 28 penetrates below the bottom plate 25 and is in transmission connection with the second rotating shaft through a second gear set.

[0044] The first driving motor 231 and the first gear set cooperate to drive the first rotating shaft and the cross plate 22 to rotate. During the rotation of the cross plate 22, the connecting column 233 will slide inside the arc-shaped groove 232. The connecting column 233 is used to connect the top plate 21 and the cross plate 22 together to improve the stability of the cross plate 22 during rotation.

[0045] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11 , the docking component 24 includes two elastic telescopic rods 241 fixedly connected to the bottom of the cross plate 22 and symmetrically distributed before and after. A pressing plate 242 is fixedly connected between the bottoms of the two elastic telescopic rods 241. A positioning block 243 is fixedly installed on the bottom of the pressing plate 242, and positioning components 244 are symmetrically distributed before and after the positioning block 243. The axis of the positioning block 243 coincides with the axis of the first rotating shaft. The positioning block 243 is inserted and matched with the central alignment ring 152. The positioning component 244 includes a first fixing block 2441 fixedly installed on the bottom of the pressing plate 242. A first movable block 2442 is slidably installed up and down on the bottom of the first fixing block 2441. A first return spring 2443 is fixedly connected between the top of the first movable block 2442 and the inner wall of the first fixing block 2441. The first movable block 2442 is inserted and matched with the positioning hole 153.

[0046] When docking the positioning mechanism 1 and the clamping mechanism 2, first insert the alignment block 243 into the central alignment ring 152. When the cross plate 22 is not parallel to the U-shaped frame 11, the positioning component 244 will be misaligned with the first positioning hole 153, causing the support frame 151 to push the first movable block 2442 back into the first fixed block 2441. Then, the first driving motor 231 and the first gear set cooperate to drive the cross plate 22 to rotate. Next, the cross plate 22 drives the elastic telescopic rod 241 and the pressing plate 242 to rotate. When the pressing plate 242 rotates, it will drive the positioning component 244 to rotate together. When the positioning component 244 moves above the first positioning hole 153, the resilience of the first return spring 2443 is used to push the first movable block 2442 downward and insert it into the first positioning hole 153, positioning the cross plate 22 through the first positioning hole 153 and making the cross plate 22 parallel to the U-shaped frame 11.

[0047] Please refer to Figure 5 、 Figure 8 、 Figure 9 and Figure 11 ,the left and right moving assembly 26 includes a second guide rail 261 fixedly installed at the bottom of the cross plate 22. A lead screw 262 is rotatably installed inside the second guide rail 261. A second slider 263 is threadedly connected to the outside of the lead screw 262. The second slider 263 is slidably installed left and right inside the second guide rail 261. A second driving motor 264 is fixedly installed at the left end of the cross plate 22. The output shaft of the second driving motor 264 is fixedly connected to the right end of the lead screw 262. The bottom plate 25 is fixedly installed at the bottom of the second slider 263.

[0048] By driving the lead screw 262 to rotate through the second driving motor 264, then driving the second slider 263 to move to the right by the lead screw 262, and then the second slider 263 drives the bottom plate 25 and the turntable 27 to move to the right, it can make the hydraulic clamping jaw 271 clamp the curbstone and move it to the right, and fit the clamped curbstone with the laid curbstone.

[0049] Please refer to Figure 6 、 Figure 9 、 Figure 10 and Figure 11 ,the locking assembly 29 includes a second fixed block 291 fixedly connected to the bottom of the bottom plate 25. A second movable block 292 is slidably installed up and down at the bottom of the second fixed block 291. A second return spring 293 is fixedly connected between the top of the second movable block 292 and the inner wall of the second fixed block 291. A second positioning hole 294 that is inserted and matched with the second movable block 292 is opened at the rear side of the turntable 27. A pull rope 295 is fixedly connected to the top of the second movable block 292. One end of the pull rope 295 away from the second movable block 292 passes through the bottom plate 25 and is fixedly connected to the right end of the second guide rail 261.

[0050] In the initial state, the second slider 263 is located at the left end of the second guide rail 261. At this time, the pulling rope 295 is in a taut state. The pulling rope 295 is used to pull the second movable block 292 into the interior of the second fixed block 291, preventing it from affecting the rotation of the turntable 27 and facilitating the hydraulic clamping jaw 271 to clamp the curbstone. After the hydraulic clamping jaw 271 clamps the curbstone, the left and right moving assembly 26 drives the bottom plate 25 to move a short distance to the right, making the pulling rope 295 no longer taut. Then, the third driving motor 28 drives the turntable 27 and the hydraulic clamping jaw 271 to rotate to adjust the direction of the curbstone clamped by the hydraulic clamping jaw 271. When the second positioning hole 294 moves to directly below the second movable block 292, the resilience of the second return spring 293 is used to push the second movable block 292 downward, causing the second movable block 292 to insert into the second positioning hole 294 to lock the bottom plate 25 and the turntable 27. At this time, the curbstone clamped by the hydraulic clamping jaw 271 is parallel to the cross plate 22, facilitating the alignment of the clamped curbstone with the laid curbstone.

[0051] Please refer to Figures 1 - 11 When in use specifically, in Step 1, place the first curbstone parallel to the road edge into the pre-dug trench. Then, the push shovel cylinder on the chassis of the excavator 3 lowers the U-shaped frame 11 outside the curbstone. When placing it, the second positioning wheel 17 lands on the edge of the front side of the road. Then, rotate the threaded rod 164 to push the movable plate 162 forward, causing the second roller 163 to move forward to clamp the curbstone together with the first roller 161.

[0052] In Step 2, the electric telescopic rod 1461 is used to push the push rod 1462 and the round rod 1463 to move to the left. Then, the round rod 1463 slides along the chute 1464 and pushes the scissor frame 142 to open outward. During the opening process of the scissor frame 142, the first slider 145 is used to push the first guide rail 144 and the cross beam 143 to move away from the U-shaped frame 11. Then, the cross beam 143 drives the first positioning wheel 13 to move away from the U-shaped frame 11, causing the first positioning wheel 13 to abut against the rear side wall of the trench (i.e., the side wall of the road). At the same time, the second positioning wheel 17 rolls along the upper end surface of the road. Then, the first positioning wheel 13 continues to expand outward to adjust the distance between the curbstone and the road.

[0053] Step 3: The excavator 3 controls the hydraulic clamping jaw 271 to move to the curbstone to be clamped through the robotic arm, grabs the second curbstone, and then moves the second curbstone above the left side of the first curbstone. Then, the clamping mechanism 2 is docked with the positioning mechanism 1. During docking, first insert the alignment block 243 into the central alignment ring 152, and then drive the cross plate 22 to rotate by the first driving motor 231. Next, the cross plate 22 drives the elastic telescopic rod 241 and the pressing plate 242 to rotate. When the pressing plate 242 rotates, it will drive the positioning component 244 to rotate together. When the positioning component 244 moves above the first positioning hole 153, use the resilience of the first return spring 2443 to push the first movable block 2442 downward and insert it into the first positioning hole 153, making the cross plate 22 parallel to the U-shaped frame 11.

[0054] Step 4: In the initial state, the second slider 263 is located at the left end of the second guide rail 261. At this time, the pull rope 295 is in a taut state. Use the pull rope 295 to pull the second movable block 292 into the interior of the second fixed block 291 to avoid affecting the rotation of the turntable 27. Drive the lead screw 262 to rotate by the second driving motor 264, and then the lead screw 262 drives the second slider 263 to move to the right. Then, the second slider 263 drives the bottom plate 25 and the turntable 27 to move a short distance to the right, making the pull rope 295 no longer taut. Then, drive the turntable 27 and the hydraulic clamping jaw 271 to rotate by the third driving motor 28 to adjust the direction of the second curbstone. When the second positioning hole 294 moves directly below the second movable block 292, use the resilience of the second return spring 293 to push the second movable block 292 downward, so that the second movable block 292 is inserted into the interior of the second positioning hole 294 to lock the bottom plate 25 and the turntable 27. At this time, the second curbstone is parallel to the cross plate 22.

[0055] Step 5: The robotic arm pushes the cross plate 22 downward, compressing the elastic telescopic rod 241 downward, so that the hydraulic clamping jaw 271 places the second curbstone into the groove flush with the first curbstone. Then, drive the lead screw 262 to rotate by the second driving motor 264, so that the second slider 263 drives the bottom plate 25 and the turntable 27 to continue moving to the right, aligning and fitting the second curbstone with the first curbstone.

[0056] Step 6: The hydraulic clamping jaw 271 releases the clamping of the second curbstone, and then the robotic arm drives the cross plate 22 to move upward, separating the alignment block 243 from the central alignment ring 152. Then, the excavator 3 drives the positioning mechanism 1 to move to the left by a distance equal to the length of one curbstone, so that the positioning mechanism 1 moves to the second curbstone. At the same time, the excavator 3 controls the clamping mechanism 2 to grab the third curbstone through the robotic arm, and then repeat Steps 3, 4, and 5 to lay the subsequent curbstones.
