[0001] The utility model relates to the technical field of road engineering construction, in particular to a geogrid laying device. Background Art
[0002] Geogrids are widely used in the construction and repair of asphalt pavements to improve the bearing capacity of subgrades and the crack resistance of asphalt pavements, thereby extending the service life of pavements.
[0003] Currently, geogrids on the market are packaged in rolls. During on-site paving, the geogrids are usually gradually laid on the road base by the method of manual unrolling. During the laying process, in order to ensure the firmness of the geogrid laying, U-shaped anchor bolts are also required to anchor the geogrid to the ground at the edge of the geogrid; in the whole laying process, the labor intensity of the operators is large, the laying efficiency is low, and the geogrid is often made of glass fiber material. Long-term high-intensity manual work endangers the health of the operators, and as the working time prolongs, the laying quality also decreases. Content of the Utility Model
[0004] In order to solve the deficiencies of the above-mentioned prior art, the utility model provides a geogrid laying device, which enables the unrolling and laying and the anchoring operations to be carried out synchronously, reduces the number of operators, minimizes the harm to the operators, reduces the labor cost, and improves the laying speed and quality.
[0005] The technical solution of the utility model is as follows: A geogrid laying device, including a vehicle body, a geogrid reel, a rolling wheel, a nail outlet bin, a horizontal nail shifting component, a vertical nail pressing component and a nail hammering component. The geogrid reel is rotationally installed in the middle of the vehicle body through a reel shaft. The rolling wheel is located inside the vehicle body and is coaxially connected with the rear wheel of the vehicle body, and is used for rolling the geogrid unrolled from the geogrid reel in the direction opposite to the advancing direction of the vehicle body. A nail outlet hole is opened at the bottom of the vehicle body near the rolling wheel. The nail outlet bin is fixed inside the vehicle body. One end of the nail outlet bin is communicated with the nail outlet hole, and the other end of the nail outlet bin is provided with a horizontal nail shifting component for pushing the U-shaped nails horizontally towards the nail outlet hole. The vertical nail pressing component and the nail hammering component are sequentially arranged inside the vehicle body above the nail outlet bin. The driving end of the nail hammering component is in clearance transmission connection with the rear wheel of the vehicle body, and the output end of the nail hammering component drives the vertical nail pressing component to act on the U-shaped nails in the nail outlet hole in the vertical direction reciprocally. By arranging the geogrid reel and the rolling wheel inside the vehicle body, as the vehicle body advances forward, the rolling wheel rolls the geogrid laid below and drives the geogrid to gradually unfold along the advancing direction of the vehicle body. At the same time, the rear wheel of the vehicle body drives the nail hammering component to move intermittently in the vertical direction. Through the cooperation of the vertical nail pressing component and the horizontal nail shifting component, the U-shaped nails in the nail outlet bin are pressed out of the nail outlet hole one by one, so as to anchor the edge of the geogrid outside the rolling wheel, realizing the synchronous progress of geogrid laying and anchoring, thereby improving the construction efficiency and ensuring the construction quality.
[0006] The horizontal nail shifting component includes a nail pushing seat, a horizontal guiding rod and a first spring. The nail outlet bin is internally provided with a storage groove for arranging U-shaped nails side by side in the horizontal direction. One end of the horizontal guiding rod is connected with the end face of the storage groove, and the other end of the horizontal guiding rod extends to one side of the nail outlet hole. The outer side of the nail pushing seat is in sliding fit with the side wall of the storage groove, and a sliding hole for sliding fit with the horizontal guiding rod is opened on the inner side of the nail pushing seat. The first spring is sleeved on the horizontal guiding rod, and both ends of the first spring are respectively connected with the nail pushing seat and the end face of the storage groove. The U-shaped nails are arranged side by side in the storage groove. As the first U-shaped nail is pressed out of the nail outlet hole downward, the nail pushing seat is pushed by the reset action of the first spring to push the subsequent U-shaped nails to move to the position of the nail outlet hole.
[0007] The vertical nail pressing component includes a pressing plate, a vertical guiding rod and a second spring. There are multiple vertical guiding rods, which are arranged circumferentially on the vehicle body outside the communicating end of the nail outlet bin. The outer side of the pressing plate is slidably connected with the vertical guiding rod through a penetrating member. A nail pressing part matched with the nail outlet hole is fixed at the bottom of the pressing plate. The second spring is sleeved on the vertical guiding rod, and both ends of the second spring are respectively connected with the vehicle body and the penetrating member.
[0008] The nail - hammering assembly includes an outer box body with an open top, a sliding frame, and a falling hammer member. The outer box body is fixed on the vehicle body between the rear wheel and the rolling wheel. The sliding frame is vertically installed on the top of the outer box body. The falling hammer member is slidably connected to the inner side of the sliding frame, and the lower end of the falling hammer member has a hammering part for pressing a vertical nail - pressing assembly. The hammering part forms the output end of the nail - hammering assembly. A rack is fixed on the outer side of the falling hammer member, and the rack forms the driving end of the nail - hammering assembly. A main driving wheel is fixed on the axle where the rear wheel is connected to the rolling wheel. A driven transmission wheel and a tooth - missing gear which are coaxially arranged are rotatably connected to the top of the outer box body through a bearing seat. The main driving wheel is drivingly connected to the driven transmission wheel through a conveyor belt. The tooth - missing gear is intermittently engaged with the rack. Through the cooperation among the main driving wheel, the conveyor belt, and the driven transmission wheel, the rear wheel drives the tooth - missing gear integrated with the driven transmission wheel to rotate. Under the intermittent cooperation of the tooth - missing gear and the rack, the falling hammer member is driven to repeatedly strike the vertical nail - pressing assembly to press out U - shaped nails one by one.
[0009] It includes a surface - pressing roller. Rocking rods are rotatably connected to both ends of the surface - pressing roller. The ends of the rocking rods are installed on the vehicle body above the geogrid reel through ear plates. The surface - pressing roller continuously contacts the geogrid on the geogrid reel under its own weight. During the whole laying process, the surface - pressing roller always presses the geogrid tightly on the geogrid reel, thus avoiding the phenomenon of the geogrid exploding and curling due to elasticity and further ensuring the laying quality.
[0010] There are two racks, which are symmetrically arranged on both sides of the falling hammer member. Any one of the racks is engaged with the tooth - missing gear. Each rack penetrates the sliding frame upward, and guide gears which are engaged with the racks are rotatably connected to both ends of the sliding frame. The setting of the double racks and the guide gears can improve the stability of the falling hammer member in the front - and - back direction in the sliding frame when the vehicle body moves forward, and ensure the continuous meshing between the rack and the tooth - missing gear.
[0011] The falling hammer member is of a cylindrical structure. A plurality of rollers are arranged at a position in the sliding frame far from the rack. Each roller is rotatably connected to the frame body of the sliding frame, and is symmetrically arranged in groups on both sides of the falling hammer member. The outer side of each roller has a curved surface structure which is matched with the outer surface of the falling hammer member. The rollers cooperate with the outer side of the falling hammer member to slide, playing a supporting role, so as to improve the stability of the falling hammer member in the left - and - right direction in the sliding frame when the vehicle body moves forward.
[0012] The outer side of the sliding frame is connected to the outer box body through a connecting member that moves along the direction away from / towards the tooth - missing gear. The connecting member includes an adjusting rod fixed on the top of the outer box body and a split - type hoop fixed on the outer side of the sliding frame. The split - type hoop is detachably connected to the adjusting rod. Through the adjustable connection of the connecting member, the driving end of the nail - hammering assembly and the tooth - missing gear are separated and combined, so as to control the vertical movement of the unilateral nail - hammering assembly to save the usage amount of U - shaped nails.
[0013] The beneficial effects of the present utility model are as follows: In this solution, a grille drum and a rolling wheel are arranged inside the vehicle body. As the vehicle body moves forward, the rolling wheel rolls over the geogrid laid below and drives the geogrid to gradually unfold along the forward direction of the vehicle body. At the same time, the rear wheels of the vehicle body drive the nail hammering assembly to move intermittently in the vertical direction. Through the cooperation of the vertical nail pressing assembly and the horizontal nail moving assembly, the U-shaped nails in the nail outlet bin are pressed out of the nail outlet holes one by one, so as to anchor the edge of the geogrid outside the rolling wheel, realizing the synchronous progress of geogrid laying and anchoring, thereby improving the construction efficiency, ensuring the construction quality, reducing the number of operators, reducing the health hazards of operators, and saving cost expenses.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] To enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the present utility model with reference to the accompanying drawings. Other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] As Figures 1-3 shown, the present utility model provides a geogrid laying device, which includes a vehicle body 1, a geogrid reel 2, a roller 3, a nail outlet bin 4, a transverse nail moving assembly 6, a vertical nail pressing assembly 7 and a nail hammering assembly 5. The geogrid 201 is wound and connected to the geogrid reel 2. The geogrid reel 2 is rotationally installed in the middle of the vehicle body 1 through a reel, specifically located between the front wheel 101 and the rear wheel 102 of the vehicle body 1. The roller 3 is located inside the vehicle body 1 and is coaxially connected to the rear wheel 102 of the vehicle body 1. The geogrid 201 on the geogrid reel 2 is unfolded in the direction opposite to the advancing direction of the vehicle body 1 and is pressed under the roller 3. A nail outlet hole 103 is opened at the bottom of the vehicle body 1 near the roller 3, and the projection of the nail outlet hole 103 below is located within the coverage of the geogrid 201 outside the roller 3. The nail outlet bin 4 is fixed inside the vehicle body 1. One end of the nail outlet bin 4 is connected to the nail outlet hole 103, and the other end of the nail outlet bin 4 is provided with a transverse nail moving assembly 6 for pushing the U-shaped nail 401 horizontally towards the nail outlet hole 103. The vertical nail pressing assembly 7 and the nail hammering assembly 5 are sequentially arranged inside the vehicle body 1 above the nail outlet bin 4. The driving end of the nail hammering assembly 5 is in clearance transmission connection with the rear wheel 102 of the vehicle body 1, and the output end of the nail hammering assembly 5 drives the vertical nail pressing assembly 7 to act vertically and reciprocally on the U-shaped nail 401 in the nail outlet hole 103. By arranging the geogrid reel 2 and the roller 3 inside the vehicle body 1, as the vehicle body 1 advances forward, the roller 3 rolls the geogrid 201 spread under it and drives the geogrid 201 to gradually unfold along the advancing direction of the vehicle body 1. At the same time, the rear wheel 102 of the vehicle body 1 drives the nail hammering assembly 5 to move intermittently in the vertical direction. Through the cooperation of the vertical nail pressing assembly 7 and the transverse nail moving assembly 6, the U-shaped nails 401 in the nail outlet bin 4 are successively pressed out of the nail outlet hole 103, so as to anchor the edge of the geogrid 201 outside the roller 3, realizing the synchronous laying and anchoring of the geogrid 201, thereby improving the construction efficiency and ensuring the construction quality.
[0023] In this embodiment, the nail outlet hole 103 is a strip-shaped hole extending along the advancing direction of the vehicle body 1, and the width of the nail outlet hole 103 is only for one U-shaped nail 401 to be discharged. The nail outlet bin 4 is arranged along the width direction of the vehicle body 1, so that the discharged U-shaped nails 401 are used to anchor on both sides of the transverse belt body of the civil engineering cut; As Figure 6As shown, the lateral nail pushing assembly 6 includes a nail pushing seat 601, a horizontal guiding rod 602 and a first spring 603. The nail discharging bin 4 is provided with a storage groove 402 for arranging U-shaped nails 401 side by side in the horizontal direction. One end of the horizontal guiding rod 602 is connected to the end face of the storage groove 402, and the other end of the horizontal guiding rod 602 extends to one side of the nail discharging hole 103. The outer side of the nail pushing seat 601 cooperates with the side wall of the storage groove 402 to slide, and a sliding hole for sliding in cooperation with the horizontal guiding rod 602 is formed in the inner side of the nail pushing seat 601. The first spring 603 is sleeved on the horizontal guiding rod 602, and both ends of the first spring 603 are respectively connected to the nail pushing seat 601 and the end face of the storage groove 402. The vertical nail pressing assembly 7 includes a pressing plate 701, a vertical guiding rod 702 and a second spring 703. There are a plurality of the vertical guiding rods 702, which are arranged circumferentially on the vehicle body 1 outside the communicating end of the nail discharging bin 4. The outer side of the pressing plate 701 is slidably connected to the vertical guiding rod through a penetrating member 704. A nail pressing part 705 matched with the nail discharging hole 103 is fixed at the bottom of the pressing plate 701. The second spring 703 is sleeved on the vertical guiding rod 702, and both ends of the second spring 703 are respectively connected to the vehicle body 1 and the penetrating member 704. Preferably, a nut 706 is threadedly connected to the vertical guiding rod 702 above the penetrating member 704 to limit the pressing plate 701 to be in the initial position, and the length of the nail pressing part 705 is not less than the maximum vertical height between the top surface of the U-shaped nail 401 in the storage groove 402 and the surface of the rolling wheel 3, so as to ensure that the nail pressing part 705 completely anchors the U-shaped nail 401 on the geogrid 201.
[0024] The U-shaped nails 401 are arranged side by side in the storage groove 402. As the nail pressing part 705 in the vertical nail pressing assembly 7 moves downward to press the first U-shaped nail 401 out of the nail discharging hole 103, under the reset action of the first spring 603, the nail pushing seat 601 pushes the subsequent U-shaped nails 401 to move to the nail discharging hole 103, and the nail pressing part 705 moves upward to the initial position with the pressing plate 701 under the reset action of the second spring 703. With the intermittent driving of the hammering and fixing assembly, the subsequent U-shaped nails 401 are successively pressed out of the nail discharging hole 103.
[0025] As Figure 3 and Figure 5As shown in the figure, the hammering and nailing assembly 5 includes an outer box body 501 with an open top, a sliding frame 503, and a falling hammer member 502. The outer box body 501 is fixed to the vehicle body 1 between the rear wheel 102 and the rolling wheel 3. A notch 506 corresponding to the position of the nail outlet bin 4 is provided on the side wall of the outer box body 501. The height of the notch 506 is not less than the sum of the height of the nail outlet bin 4 and the height of the U-shaped nail 401, which facilitates the filling operation of the U-shaped nail 401 in the nail outlet bin 4 at the notch 506. The sliding frame 503 is vertically installed on the top of the outer box body 501. The falling hammer member 502 is slidably connected to the inner side of the sliding frame 503, and the lower end of the falling hammer member 502 has a hammering part 505 for pressing the vertical nail pressing assembly 7. The hammering part 505 forms the output end of the hammering and nailing assembly 5. A rack 504 is fixed to the outer side of the falling hammer member 502, and the rack 504 forms the driving end of the hammering and nailing assembly 5. A main driving wheel 9 is fixed to the axle connecting the rear wheel 102 and the rolling wheel 3. A driven transmission wheel 10 and a toothless gear 8 arranged coaxially are rotatably connected to the top of the outer box body 501 through a bearing seat 12. The main driving wheel 9 is in transmission connection with the driven transmission wheel 10 through a conveyor belt 11. The toothless gear 8 is intermittently engaged with the rack 504. Through the cooperation among the main driving wheel 9, the conveyor belt 11, and the driven transmission wheel 10, the rear wheel 102 drives the toothless gear 8 integrated with the driven transmission wheel 10 to rotate. Under the intermittent cooperation of the toothless gear 8 and the rack 504, the falling hammer member 502 is driven to reciprocally strike the vertical nail pressing assembly 7, thereby pressing out the U-shaped nails 401 one by one.
[0026] To avoid the phenomenon of the geogrid 201 exploding and curling due to its elasticity and further ensure the laying quality, as Figure 4 shown in the figure, the device further includes a surface pressing roller 17. Both ends of the surface pressing roller are rotatably connected with rocker arms 18. The ends of the rocker arms 18 are installed on the vehicle body 1 above the grille drum 2 through ear plates 19. The surface pressing roller is in continuous contact with the geogrid 201 on the grille drum 2 under its own weight. Thus, during the entire laying process, the surface pressing roller 17 always presses the geogrid 201 tightly against the grille drum 2.
[0027] As Figure 3 shown in the figure, there are two racks 504, which are symmetrically arranged on both sides of the falling hammer member 502. Any one of the racks 504 is engaged with the toothless gear 8. As Figure 5 shown in the figure, each rack 504 penetrates through the sliding frame 503 upward, and guide gears 13 engaged with the racks 504 are rotatably connected to both ends of the sliding frame 503. By setting the double-rack 504 and guide gear 13 structure, the stability of the falling hammer member 502 in the front-back direction in the sliding frame 503 can be improved when the vehicle body 1 moves forward, and the continuous meshing of the rack 504 and the toothless gear 8 can be ensured.
[0028] In order to improve the stability of the drop hammer part 502 in the left - right direction within the sliding frame 503 when the vehicle body 1 is moving forward. As Figure 5 shown, the drop hammer part 502 has a cylindrical structure. A number of rollers 14 are provided at a position in the sliding frame 503 far from the rack 504. Each of the rollers 14 is rotatably connected to the frame of the sliding frame 503 and is symmetrically arranged in groups on both sides of the drop hammer part 502. The outer side of each roller 14 has a curved surface structure that matches the outer surface of the drop hammer part 502. The rollers 14 cooperate with the outer side of the drop hammer part 502 to slide, providing a lateral supporting force for the drop hammer part 502.
[0029] As Figure 5 shown, the outside of the sliding frame 503 is connected to the outer box body 501 through a connecting member that moves along the direction away from / towards the missing - tooth gear 8. Specifically, the connecting member includes an adjusting rod 15 fixed to the top of the outer box body 501 and a split hoop 16 fixed to the outside of the sliding frame 503. The split hoop 16 is detachably connected to the adjusting rod 15. By moving the sliding frame 503 to the first position through the connecting member, at this time, the frame on the outside of the sliding frame 503 abuts against the lower frame of the bearing seat 12, and at the same time, the rack 504 meshes with the missing - tooth gear 8, and the driving end of the nail - hammer assembly 5 is in the driving state. By moving the sliding frame 503 to any second position through the connecting member, the rack 504 is separated from the missing - tooth gear 8, and at this time, the driving end of the nail - hammer assembly 5 is in the stop state. The switching of the two states of the nail - hammer assembly 5 can control the vertical movement of only any one - side nail - hammer assembly 5.
[0030] Specifically, when laying a wide road surface, it is usually necessary to lay a plurality of side - by - side geogrids 201 along the width direction of the road. First, move the nail - hammer assembly 5 close to one edge (such as the left edge) of the road to the first position, and move the nail - hammer assembly 5 far from the left edge to the second position, so as to anchor only the side of the geogrid 201 close to the left edge of the road. Anchor nails are successively carried out between adjacent geogrids 201 until reaching the right edge of the road. Move the nail - hammer assembly 5 on the left to the second position, and move the nail - hammer assembly 5 on the right to the first position, and only anchor the side of the geogrid 201 close to the right edge of the road, so as to achieve the effect of saving the usage amount of U - shaped nails 401.
[0031] When implementing the above technical solution, the grille reel 2 with the geogrid 201 is sleeved on the reel, and the reel is mounted on the mounting frame (not shown in the figure) inside the vehicle body 1. The geogrid 201 is unfolded towards the direction opposite to the advancing direction of the vehicle body 1 to below the roller 3, and the end face of the geogrid 201 is pre-fixed to the road base using anchor nails. Then, the vehicle body 1 is advanced forward. As the rear wheel 102 rotates counterclockwise, the main driving wheel 9 drives the driven wheel and the toothless gear 8 to rotate counterclockwise through the conveyor belt 11. The toothed part of the toothless gear 8 meshes with the rack 504, thereby driving the drop hammer part 502 to move upward until the toothed part of the toothless gear 8 is completely disengaged from the rack 504. After the drop hammer part 502 reaches the highest point, it falls and impacts the pressing plate 701, driving the nail pressing part 705 to move downward and pressing the U-shaped nail 401 from the nail outlet hole 103 onto the transverse belt of the geogrid 201. As the toothed part of the toothless gear 8 meshes with the rack 504 again, the drop hammer part 502 moves upward, and the pressing plate 701 returns to the initial position under the reset action of the second spring 703. The nail pushing seat 601 pushes the subsequent U-shaped nails 401 to the nail outlet hole 103 under the reset action of the first spring 603. The drop hammer part 502 repeats the previous operation, and then the U-shaped nails 401 are successively driven out and anchored on the geogrid 201, realizing the synchronous progress of the laying and anchoring of the geogrid 201, improving the construction efficiency and ensuring the construction quality.

Any person skilled in the art in the technical field disclosed by the present application can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present application, and these modifications or substitutions should all be covered within the protection scope of the present application.
