Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically a road compaction device for roadbed and pavement engineering construction. Background Technology

[0002] In the early stages of road construction, compaction equipment is often used to compact the road surface. This makes the road surface smoother and increases the degree of compaction, thereby extending the service life of the entire road surface and meeting the compaction requirements.

[0003] During highway construction, the process of compacting the road surface involves manually holding a compactor and controlling its movement to compact the soil surface.

[0004] Patent document CN 222100560 U discloses a road compaction device for roadbed and pavement construction. During operation, the device first adjusts the hydraulic cylinder, which in turn moves adjusting rod one and adjusting rod two, thereby moving the adjusting connecting plate and adjusting the distance between the compaction block and the ground. Then, the rotation of the compaction motor drives the crankshaft, allowing the device to be moved manually, thus changing the compaction position and facilitating switching of compaction points. Furthermore, the impact force of the compaction device is not directly transmitted to the worker, reducing the workload and improving user comfort. Also, since the worker's hands do not directly contact the compaction device, there is no risk of the device accidentally slipping from their hand due to the impact force.

[0005] In the aforementioned prior art, during the process of compacting the road surface, the compaction plate is prone to wear and tear due to prolonged use, and the lack of a protective structure for the compaction plate affects its service life. Utility Model Content

[0006] The purpose of this utility model is to provide a road compaction device for roadbed and pavement construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A road compaction device for roadbed and pavement construction includes a housing, within which a frame is movably installed. A guide sleeve is fixedly connected through the bottom of the frame, and an output column is slidably connected within the guide sleeve. A compaction plate is fixedly connected to the bottom end of the output column. A pad adapted to the compaction plate is provided on the bottom surface of the compaction plate. An outer groove is fastened to the outer sides of the pad and the compaction plate. Threaded columns are symmetrically fixedly connected to the inner side of the outer groove, penetrating the pad and the compaction plate, and threaded with locking nuts. A drive mechanism is provided at the top of the output column. Casters are symmetrically and rotatably installed at the bottom of the housing, and a push handle is fixedly installed on the rear side of the housing.

[0009] As a further embodiment of this utility model: the drive mechanism includes a drive motor, a crankshaft and a crank arm. The drive motor is fixedly installed on the top surface of the frame, the crankshaft is rotatably connected to the inner side of the top of the frame, one end of the crank arm is rotatably connected to the crankshaft, and the other end of the crank arm is rotatably installed with the output column.

[0010] As a further embodiment of this utility model: the output end of the drive motor is fixedly connected to a pulley, and the end of the crankshaft is fixedly connected to a flywheel, which is connected to the pulley via a belt.

[0011] As a further improvement of this utility model: each of the four corners of the frame is fixedly connected with an adjusting rod, and a sliding seat is slidably sleeved on the outer side of the adjusting rod, and the sliding seat is fixedly connected to the inner wall of the shell.

[0012] As a further embodiment of this utility model: the top end of the adjusting rod slides through the top surface of the housing, and a bracket is fixedly connected to the top surface of the housing corresponding to the adjusting rod. After the adjusting rod slides through the bracket, it is connected to a spring damper, and the spring damper is fixedly connected to the support frame.

[0013] As a further improvement of this utility model: threaded rods are fixedly connected to all four sides of the support frame, and the threaded rods movably pass through the top of the bracket and are threadedly connected to adjusting nuts on both sides of the top of the bracket.

[0014] As a further improvement of this utility model, a mobile power supply and a switch are fixedly installed on the top surface of the housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model features a mating plate on the bottom surface of the compaction plate, with both plates having an outer groove fastened to their outer sides and secured by threaded posts and locking nuts. This structure isolates the compaction plate from direct impact with the road surface, and the mating plate, acting as a buffer layer, is replaceable, thus reducing wear on the main compaction plate. It avoids the problem of the compaction plate being directly exposed to abrasive environments in traditional technologies, extending the overall service life of the device and reducing maintenance costs.

[0017] 2. This utility model is equipped with shock-absorbing components such as spring dampers and adjusting rods. During compaction, the impact force is transmitted to the adjusting rod through the frame, and the vibration is absorbed by the spring dampers, thereby reducing the shaking of the shell and effectively reducing the vibration experienced by the operator's hands. This avoids the risk of equipment falling off due to impact force and improves construction safety and comfort.

[0018] 3. This utility model adjusts the position of the threaded rod by adjusting the nut, thereby adjusting the distance between the support frame and the bracket, and thus changing the height of the frame. This adjustability allows the device to adapt to different compaction depth requirements, such as for the initial leveling or fine compaction stages of roadbeds. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5In this embodiment of the utility model, a road compaction device for roadbed and pavement construction includes a housing 1. A frame 2 is movably installed inside the housing 1. A guide sleeve 3 is fixedly connected through the bottom of the frame 2. An output column 4 is slidably connected inside the guide sleeve 3. A compaction plate 5 is fixedly connected to the bottom end of the output column 4. A pad 6 that matches the bottom surface of the compaction plate 5 is provided. An outer groove 7 is fastened to the outer sides of the pad 6 and the compaction plate 5. A threaded column 8 is symmetrically fixedly connected to the inner side of the outer groove 7, passing through the pad 6 and the compaction plate 5 and then threadedly connected to a locking nut 9. A round hole for the threaded column 8 to pass through is opened on both the pad 6 and the compaction plate 5. A drive mechanism 10 is provided at the top of the output column 4. Casters 11 are symmetrically rotated and installed at the bottom of the housing 1. A push handle 12 is fixedly installed on the rear side of the housing 1.

[0027] The outer tank 7 is fixed to the tamping plate 5 by threaded column 8 and locking nut 9, and is isolated by pad 6. The output column 4 can be driven to move up and down reciprocally under the guidance of guide sleeve 3 by drive mechanism 10, thereby driving the tamping plate 5 to perform tamping operation downward. The housing 1 is pushed by push handle 12, thereby moving by caster 11.

[0028] The drive mechanism 10 includes a drive motor 13, a crankshaft 14, and a crank 15. The drive motor 13 is fixedly installed on the top surface of the frame 2. The crankshaft 14 is rotatably connected to the inner top of the frame 2. One end of the crank 15 is rotatably connected to the crankshaft 14, and the other end of the crank 15 is rotatably installed with the output column 4.

[0029] The output end of the drive motor 13 is fixedly connected to the pulley 16, and the end of the crankshaft 14 is fixedly connected to the flywheel 17. The flywheel 17 is connected to the pulley 16 via the belt 18.

[0030] The drive motor 13 drives the pulley 16 to rotate, and the pulley 16 drives the flywheel 17 to rotate through the belt 18, which in turn drives the crankshaft 14 to rotate. The crankshaft 14 drives the output shaft 4 to reciprocate under the guidance of the guide sleeve 3 through the crank 15.

[0031] Adjusting rods 19 are fixedly connected through each of the four corners of the frame 2. Sliding seats 20 are slidably sleeved on the outer side of the adjusting rods 19, and the sliding seats 20 are fixedly connected to the inner wall of the shell 1.

[0032] The top end of the adjusting rod 19 slides through the top surface of the housing 1. A bracket 21 is fixedly connected to the top surface of the housing 1 corresponding to the adjusting rod 19. After the adjusting rod 19 slides through the bracket 21, it is connected to the spring damper 22. The bracket 21 and the top of the housing 1 are both provided with a hole for the adjusting rod 19 to pass through and slide. The spring damper 22 is fixedly connected to the support frame 23.

[0033] The frame 2 can move within the housing 1 through the cooperation of the adjusting rod 19 and the sliding seat 20. When the road surface is compacted, the reverse force of the compaction plate is applied to the frame 2 and buffered by the spring damper 22, thereby reducing the vibration amplitude of the housing 1.

[0034] The support frame 23 is fixedly connected to threaded rods 24 on all four sides. The threaded rods 24 move through the top of the bracket 21 and are threadedly connected to adjusting nuts 25 on both sides of the top of the bracket 21.

[0035] By rotating the adjusting nut 25, the position of the adjusting nut 25 on the threaded rod 24 can be controlled, thereby adjusting the distance between the support frame 23 and the bracket 21, and thus controlling the setting height of the frame 2, making it convenient to control the height of the compacted surface.

[0036] A power bank 26 and a switch 27 are fixedly installed on the top surface of the housing 1.

[0037] Switch 27 is used to control the start and stop of drive motor 13, and mobile power supply 26 is used to supply power to drive motor 13.

[0038] The working principle of this utility model is as follows:

[0039] In use, the housing 1 is pushed by the push handle 12, thereby moving via the casters 11. The outer groove 7 is fixed to the compaction plate 5 by the threaded post 8 and the locking nut 9, and is isolated by the pad 6. By rotating the adjusting nut 25, the position of the adjusting nut 25 on the threaded rod 24 can be controlled, thereby adjusting the distance between the support frame 23 and the bracket 21, and thus controlling the setting height of the frame 2, which facilitates the control of the compaction surface height. The drive motor 13 drives the pulley 16 to rotate, and the pulley 16 drives the flywheel 17 to rotate via the belt 18, which in turn drives the crankshaft 14 to rotate. The crankshaft 14 drives the output shaft 4 to reciprocate under the guidance of the guide sleeve 3 via the crank 15, thereby driving the compaction plate 5 to move downward for compaction. When compacting the road surface, the reverse force of the compaction plate is applied to the frame 2. The frame 2 can move within the housing 1 by the cooperation of the adjusting rod 19 and the sliding seat 20, and is buffered by the spring damper 22, thereby reducing the vibration amplitude of the housing 1.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
