Description

Technical Field

[0001] This utility model relates to the technical field of road construction equipment, specifically to a roadbed compaction device used in road construction. Background Technology

[0002] In road construction, foundation compaction is a crucial step. High-quality foundation compaction provides a stable base for road paving, ensuring the road has good load-bearing capacity and durability in subsequent use.

[0003] Traditional roadbed compaction devices have certain shortcomings in practical applications. When compacting the roadbed, these traditional devices only perform the function of compacting the soil. Due to the lack of a simultaneous leveling mechanism, small uneven steps often remain on the roadbed surface after compaction, caused by the compaction process. These uneven steps can affect subsequent road construction, requiring construction workers to use additional leveling equipment and spend extra time on separate leveling, which not only increases the complexity of construction but may also affect construction efficiency and costs.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a roadbed compaction device for road construction, comprising a movable chassis, at least one slot on the upper surface of the movable chassis, linear bearings fixedly mounted at both ends inside the slot, guide rods slidably mounted inside the linear bearings, a tamping hammer fixedly mounted between the lower ends of the two guide rods, a compaction plate fixedly mounted at the lower end of the tamping hammer, a motor fixedly mounted on the upper surface of the movable chassis, a drive disc fixedly mounted on the drive shaft of the motor, a connecting rod rotatably mounted near the edge of the side of the drive disc, the other end of the connecting rod passing through the slot and hinged to the upper end of the tamping hammer, and a pressure roller mechanism for assisting leveling fixedly mounted near one end of the bottom of the movable chassis.

[0008] Furthermore, the pressure roller mechanism includes a spring telescopic mechanism fixedly mounted on the bottom of the movable chassis, and a pressure roller assembly is fixedly mounted on the lower end of the spring telescopic mechanism.

[0012] (III) Technical Effects

[0025] Combined with appendix Figure 1 To be continued Figure 7 A roadbed compaction device for road construction includes a mobile chassis 1, which includes a base plate 18 and rollers 19 fixedly installed at the bottom corner of the base plate 18. It also includes a handrail 20 fixedly installed on the upper surface of the base plate 18. The upper surface of the mobile chassis 1 has at least one slot 2. Linear bearings 3 are fixedly installed at both ends inside the slot 2. Guide rods 4 are slidably installed inside the linear bearings 3. A tamping hammer 5 is fixedly installed between the lower ends of the two guide rods 4. A compaction plate 6 is fixedly installed at the lower end of the tamping hammer 5. A motor 7 is fixedly installed on the upper surface of the mobile chassis 1. A drive disc 8 is fixedly installed on the drive shaft of the motor 7. A connecting rod 9 is rotatably installed on the side of the drive disc 8 near its edge. The other end of the connecting rod 9 passes through the slot 2 and is hinged to the upper end of the tamping hammer 5. A pressure roller mechanism for assisting leveling is fixedly installed near one end of the bottom of the mobile chassis 1.

[0026] In this embodiment, as a preferred technical solution, the pressure roller mechanism includes a spring telescopic mechanism 10 fixedly disposed at the bottom of the movable chassis 1. A pressure roller assembly 11 is fixedly disposed at the lower end of the spring telescopic mechanism 10. The spring telescopic mechanism 10 includes a cavity 12 fixedly disposed at the bottom of the movable chassis 1. An insert rod 13 is inserted and connected to the bottom of the cavity 12. A limiting plate 14 is fixedly disposed at one end of the insert rod 13 that extends into the cavity 12.

[0027] The working principle of this utility model's roadbed compaction device for road construction is as follows: A motor 7 drives a drive disc 8 to rotate. The drive disc 8, through a connecting rod 9, drives a tamping hammer 5 to reciprocate up and down under the guidance of a linear bearing 3 and a guide rod 4. The compaction plate 6 at the lower end of the tamping hammer 5 compacts the roadbed. Simultaneously, during the movement of the movable chassis 1, the pressure roller mechanism at the bottom assists in leveling the compacted area. The spring telescopic mechanism 10 in the pressure roller mechanism can adaptively adjust the height of the pressure roller assembly 11 according to the undulations of the roadbed surface, ensuring that the pressure roller 17 is always in contact with the roadbed surface, achieving synchronous leveling.

[0028] The working process of this utility model's roadbed compaction device for road construction is as follows:

[0029] 1. First, the device is moved to the starting position of the roadbed that needs to be compacted by the rollers 19 of the mobile chassis 1. The construction workers can push the device by the handrail 20.

[0030] 2. Start motor 7, which drives drive disc 8 to rotate. As drive disc 8 rotates, connecting rod 9, which is rotatably connected near the edge on the side, moves along with the rotation of the disc.

[0031] 3. The other end of the connecting rod 9 is hinged to the upper end of the rammer 5. As the connecting rod 9 moves, it drives the rammer 5 to move up and down. The rammer 5 relies on the guide rods 4 installed in the linear bearings 3 at both ends to ensure the vertical stability of its movement.

[0032] 4. The tamping plate 6 at the lower end of the tamping hammer 5 repeatedly tamps the roadbed as the tamping hammer 5 moves up and down.

[0033] 5. During the movement of the mobile chassis 1, the pressure roller mechanism starts to work. The pressure roller 17, which is rotatably installed inside the U-shaped frame 16 fixed at the lower end of the insertion rod 13, is always in contact with the roadbed surface under the action of the spring telescopic mechanism 10. As the mobile chassis 1 moves, it levels the roadbed after compaction and removes the small uneven steps caused by compaction.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
