Abstract
Description
Technical Field
[0001] This utility model relates to the field of road shoulder construction, specifically to a road shoulder construction device with a compaction mechanism. Background Technology
[0002] Shoulder construction is an important part of highway engineering. Its main functions are to protect the stability of the main structure such as the driving lane, provide temporary parking spaces, increase driving safety and comfort, and provide passage space for pedestrians and bicycles. Shoulder construction devices are mechanical equipment specifically used for constructing shoulders. They play a vital role in the shoulder construction process. Appropriate construction devices can be selected according to the specific requirements of shoulder construction, such as width, height, and material type.
[0003] A search revealed a novel highway shoulder construction device (publication number CN214328444U). This device, belonging to the field of shoulder construction technology, includes a vehicle body. A reversible motor is fixedly connected to the upper surface of the vehicle body's middle section. A threaded rod is fixedly connected to the output end of the motor. The bottom end of the threaded rod penetrates the middle of the vehicle body and is located below the middle section. A movable plate is provided on the outer surface of the threaded rod, and a threaded hole adapted to the threaded rod is opened in the middle of the movable plate. This invention, through the coordinated arrangement of the reversible motor, threaded rod, movable plate, U-shaped mounting plate, motor, shaft, gear, movable frame, gear rack, connecting rod, leveling block, support block, guide rod, fixing block, limiting plate, groove, sliding rod, and pusher, enables a single person to manually push the device to complete the leveling work during shoulder construction. This saves the time and effort of manual removal, resulting in higher construction efficiency and lower labor costs.
[0004] In the use of existing shoulder construction devices, the lack of a compaction mechanism prevents the concrete from being effectively compacted during construction. This results in insufficient density of the shoulder, which makes it prone to deformation and settlement under vehicle loads, thus affecting the stability and service life of the road. Furthermore, the shoulder construction devices in the aforementioned comparative case also lack a compaction mechanism, which will compromise the smoothness of the concrete over long-term use, affecting construction efficiency and extending the construction period.
[0005] Therefore, it is necessary to invent a shoulder construction device with a compaction mechanism to solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a shoulder construction device with a compaction mechanism. This device incorporates a built-in bucket, a side shoulder frame, a compaction frame, a reciprocating turntable, a movable rod, a reciprocating rod, a compaction hammer rod, and a compaction plate to achieve the compaction mechanism. This mechanism increases density, enhancing the shoulder's load-bearing capacity and stability, reducing shoulder deformation and settlement caused by vehicle loads, rainwater erosion, and other factors, thereby extending the shoulder's service life. Furthermore, the compaction step allows for continuous construction, following the shoulder construction process without requiring equipment changes or interruptions, thus improving construction efficiency. The automation of the compaction process also reduces reliance on manual operation, further shortening the construction cycle. Simultaneously, the compaction mechanism ensures the shoulder's... Uniform compaction and reciprocating tamping help eliminate unevenness on the shoulder surface, improve road surface smoothness, and thus enhance the overall quality of the road. This addresses the problem in existing shoulder construction devices where the lack of a compaction mechanism prevents effective compaction of the concrete during construction, leading to insufficient shoulder density. Insufficiently compacted shoulders are prone to deformation and settlement under vehicle loads, affecting road stability and service life. Furthermore, the shoulder construction devices in the aforementioned comparative case also lack a compaction mechanism, which would compromise the smoothness of the concrete over long-term use, impacting construction efficiency and extending the construction period.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a shoulder construction device with a compaction mechanism, comprising a vehicle body and a main body for pushing the shoulder construction components to move;
[0008] An external fixing frame is installed on the top of the vehicle body for internal installation of the built-in bucket. A material pump is fixedly installed in front of the external fixing frame, and a material conveying pipe is fixedly installed at the output end of the material pump. A side shoulder frame is threadedly connected to the external fixing frame.
[0009] A compaction frame, located on the left side of the outer fixed frame, is used to connect and install a servo motor. The output end of the servo motor is rotatably connected to a reciprocating turntable. A movable rod is fixedly installed on the outside of the reciprocating turntable. A reciprocating rod is movably connected to the outside of the movable rod. A connecting plate is movably connected to the other end of the reciprocating rod. A compaction hammer rod is fixedly installed at the bottom of the connecting plate. A compaction plate is fixedly installed at the bottom of the compaction hammer rod.
[0010] Preferably, a lid is provided above the built-in bucket, a drive motor is fixedly provided above the lid, a transmission rod is rotatably connected to the output end of the drive motor, and a stirring blade is fixedly installed on the outside of the transmission rod.
[0011] Preferably, a shoulder plate is fixedly installed at the bottom of the side shoulder frame, and a material discharge cylinder is fixedly installed inside the side shoulder frame.
[0012] Preferably, the compaction hammer rod is slidably connected to the compaction frame, and the compaction hammer rod is fixedly connected to the compaction plate.
[0013] Preferably, an adjustment frame is fixedly installed on the other side of the compaction frame, a telescopic cylinder is fixedly installed above the adjustment frame, and a push block is fixedly installed at the front end of the telescopic cylinder.
[0014] Preferably, a connecting seat is fixedly installed at the bottom of the pushing block, and a shaping plate is fixedly installed at the bottom of the connecting seat.
[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0016] This utility model includes an internal bucket, a side shoulder frame, a compaction frame, a reciprocating turntable, a movable rod, a reciprocating rod, a compaction hammer rod, and a compaction plate. When using this shoulder construction device, as the vehicle slowly moves forward, the concrete in the internal bucket passes through the side shoulder frame to complete the shoulder construction. Then, a servo motor drives the reciprocating turntable to rotate, causing the reciprocating rod to move up and down synchronously. The reciprocating rod can then pull the compaction hammer rod to slide up and down within the compaction frame, allowing the compaction plate to reciprocate and compact the shoulder below. This compaction process, performed after construction, increases the density of the shoulder, giving the shoulder construction device a compaction mechanism. Increasing compaction helps enhance the load-bearing capacity and stability of road shoulders, reducing deformation and settlement caused by vehicle loads, rainwater erosion, and other factors, thereby extending the service life of road shoulders. Moreover, allowing the compaction process to follow the road shoulder construction process continuously without the need to change equipment or interrupt construction improves construction efficiency. The automation of the compaction process also reduces reliance on manual operation, further shortening the construction cycle. At the same time, the compaction mechanism can ensure that the compaction degree of the road shoulder is uniform and consistent, and the reciprocating tamping method also helps to eliminate unevenness on the road shoulder surface, improve the smoothness of the road surface, and thus improve the overall quality of the road.
[0017] This utility model includes an adjustment frame, a telescopic cylinder, a pushing block, a connecting seat, and a shaping plate. When using this shoulder construction device, since the roadbed is constructed and compacted first, the density of the shoulder changes after compaction. The telescopic cylinder can drive the pushing block to slide back and forth on the adjustment frame, thereby adjusting the position of the connecting seat and the shaping plate. This allows the shaping plate to fit against the outside of the shoulder, performing a secondary shaping of the compacted shoulder. This results in some unevenness on the surface of the compacted shoulder. Through the secondary shaping of the shaping plate, the height and slope of the shoulder surface can be precisely adjusted to achieve the design requirements for flatness. This not only improves the aesthetics of the road but also ensures the safety and comfort of driving. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This utility model provides, for example Figure 1-5 The illustrated shoulder construction device with a compaction mechanism includes a vehicle body 1, a main body for pushing the shoulder construction components to move.
[0028] An external fixed frame 2 is set above the vehicle body 1 for internal installation of the built-in bucket 3. A material pump 8 is fixedly installed in front of the external fixed frame 2, and a material conveying pipe 9 is fixedly installed at the output end of the material pump 8. A side shoulder frame 10 is threadedly connected to the external fixed frame 2.
[0029] The compaction frame 13 is located on the left side of the outer fixed frame 2 and is used to connect and install the servo motor 14. The output end of the servo motor 14 is rotatably connected to the reciprocating turntable 15. The reciprocating turntable 15 is fixedly mounted on the outside of the reciprocating turntable 15. The reciprocating rod 17 is movably connected to the outside of the reciprocating rod 16. The other end of the reciprocating rod 17 is movably connected to the connecting plate 18. The bottom of the connecting plate 18 is fixedly mounted with the compaction hammer rod 19. The bottom of the compaction hammer rod 19 is fixedly mounted with the compaction plate 20. The servo motor 14 drives the reciprocating turntable 15 to rotate, so that the reciprocating rod 17 also moves up and down synchronously. The reciprocating rod 17 can pull the compaction hammer rod 19 to slide up and down in the compaction frame 13, so that the compaction plate 20 reciprocates and compacts the road shoulder below. In this way, the road shoulder is compacted after the construction is completed, which improves the density of the road shoulder and gives the road shoulder construction device a compaction mechanism.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a lid 4 is provided above the inner tank 3, and a drive motor 5 is fixedly installed above the lid 4. The output end of the drive motor 5 is rotatably connected to a transmission rod 6, and a mixing blade 7 is fixedly installed on the outside of the transmission rod 6. The rotation of the transmission rod 6 and the mixing blade 7 keeps the concrete stored in the inner tank 3 in a flowing state, thereby assisting the shoulder construction device in completing the shoulder construction work. A shoulder construction plate 11 is fixedly installed at the bottom of the side shoulder frame 10, and a discharge cylinder 12 is fixedly installed inside the side shoulder frame 10. The material cylinder 12 is used to carry concrete for pouring. Together with the side shoulder frame 10 and shoulder plate 11, it allows the vehicle body 1 to complete the shoulder construction during the forward movement. The compaction hammer rod 19 is slidably connected to the compaction frame 13 and fixedly connected to the compaction plate 20. The servo motor 14 drives the reciprocating turntable 15 to rotate, so that the reciprocating rod 17 also moves up and down synchronously. The reciprocating rod 17 can pull the compaction hammer rod 19 to slide up and down in the compaction frame 13, so that the compaction plate 20 can reciprocate and compact the shoulder below.
[0031] like Figure 1 , Figure 4 and Figure 5 As shown, an adjustment frame 21 is fixedly installed on the other side of the compaction frame 13. A telescopic cylinder 22 is fixedly installed above the adjustment frame 21. A push block 23 is fixedly installed at the front end of the telescopic cylinder 22. Since the roadbed is constructed and compacted first, the compaction density of the road shoulder changes. The telescopic cylinder 22 can drive the push block 23 to slide back and forth on the adjustment frame 21, thereby adjusting the position of the connecting seat 24 and the shaping plate 25, so that the shaping plate 25 fits against the outside of the road shoulder. The connecting seat 24 is fixedly installed at the bottom of the push block 23, and the shaping plate 25 is fixedly installed at the bottom of the connecting seat 24. Through the secondary shaping of the shaping plate 25, the height and slope of the road shoulder surface can be precisely adjusted to achieve the flatness required by the design.
[0032] The working principle of this utility model is as follows: First, connect the external power supply and pour a certain amount of concrete into the inner tank 3. Then, turn on the drive motor 5 to rotate the transmission rod 6 and the mixing blade 7. This keeps the concrete in the inner tank 3 in a flowing state, thus assisting the shoulder construction device in completing the shoulder construction work. Next, the shoulder construction device can be pushed by the vehicle body 1 to carry out the shoulder construction work. First, turn on the feed pump 8 to allow the feed pump 8 to draw concrete from the inner tank 3 through the feed pipe 9 and input it into the discharge cylinder 12 of the side shoulder frame 10. As the vehicle body 1 slowly moves forward, the concrete in the built-in bucket 3 passes through the side shoulder frame 10 to complete the shoulder construction. Then, the servo motor 14 is switched on, driving the reciprocating turntable 15 to rotate, causing the reciprocating rod 17 to move up and down synchronously. The reciprocating rod 17 then pulls the compaction hammer rod 19 to slide up and down in the compaction frame 13, allowing the compaction plate 20 to reciprocate and compact the shoulder below. This compaction after construction increases the density of the shoulder, giving the shoulder construction device a compaction mechanism. This compaction mechanism improves density and helps... To enhance the load-bearing capacity and stability of the road shoulder, reduce deformation and settlement caused by vehicle loads, rainwater erosion, and other factors, thereby extending the service life of the road shoulder, and since the roadbed is constructed and compacted beforehand, the density of the compacted road shoulder changes. The telescopic cylinder 22 can be activated, allowing it to drive the push block 23 to slide back and forth on the adjustment frame 21, thereby adjusting the position of the connecting seat 24 and the shaping plate 25. This allows the shaping plate 25 to fit against the outside of the road shoulder, performing a secondary shaping of the compacted road shoulder. This process results in some unevenness on the surface of the compacted road shoulder. The phenomenon is that, through the secondary shaping of the shaping plate 25, the height and slope of the shoulder surface can be precisely adjusted to achieve the flatness required by the design. In this way, as the shoulder building device moves forward, the shoulder building work is completed. Finally, after completing the installation and use of all the shoulder building devices according to the above operations, turn off the switch of the drive motor 5, the switch of the material pump 8, the switch of the servo motor 14, and the switch of the telescopic cylinder 22. If it is not used for a long time, the external power supply can be cut off. In this way, the use process of the shoulder building device with compaction mechanism is completed.
[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
