Description

Technical Field

[0001] This utility model belongs to the field of construction technology, specifically relating to a roadbed compaction device. Background Technology

[0002] A roadbed compaction device is a mechanical equipment used in road construction and maintenance. It is primarily used to compact the roadbed and soil to ensure the road's strength and stability. Roadbed compaction devices play a crucial role in road construction, maintenance, and repair. They can be used for the construction of new roads as well as for repairing and improving the roadbed of existing roads. Through effective compaction, it can increase the road's load-bearing capacity, reduce the risk of settlement, and extend the road's service life.

[0003] Utility model patent CN208152004U discloses a roadbed construction tamping and compaction device, including a first support, with support columns symmetrically fixedly connected to the lower surface of the first support, a second support fixedly connected to the end of the support columns away from the first support, a vertical plate fixedly connected to the left end face of the first support, a push handle fixedly connected to the side of the vertical plate away from the first support, a counterweight fixedly connected to the upper surface of the first support, a connecting rod fixedly connected to the side of the counterweight away from the vertical plate, and a tamping mechanism fixedly connected to the end of the connecting rod away from the counterweight. An installation opening is provided on the second support, and mounting seats are symmetrically fixedly connected to the lower surface of the first support. This utility model uses a hydraulic cylinder to drive the piston rod to retract, causing the roller to retract into the installation opening, thus transferring the load-bearing weight of the device from the roller to the second support. Combined with the weight of the counterweight, this prevents the tamping mechanism from shifting during operation, making the tamping operation more orderly.

[0004] In actual use, multiple hydraulic cylinders are used to switch between the second support for stable support or the rollers for movement. However, the simultaneous operation of multiple hydraulic cylinders is inconvenient to control and the structure is too complex, which can easily lead to component damage and reduce the stability of the device.

[0005] Therefore, it is necessary to provide new roadbed compaction devices to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a roadbed tamping and compaction device to solve the problems existing in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a top plate, with multiple connecting rods fixedly connected to the bottom of the top plate, a base plate fixedly connected to the bottom of each connecting rod, a stable support mechanism provided at the bottom of the top plate, the stable support mechanism being used to switch between walking and stable support states, a mounting base fixedly connected to the top of the top plate, a connecting plate fixedly connected to one side of the mounting base, a hydraulic rammer fixedly connected to one side of the connecting plate, and a rammer block fixedly connected to the bottom of the hydraulic rammer.

[0008] In order to achieve the effect of moving the lifting plate up and down, preferably, the stabilizing support mechanism includes a hydraulic telescopic rod, which is set at the bottom of the top plate. The top rod of the hydraulic telescopic rod is fixedly connected to a connecting block, and the lifting plate is fixedly connected to one side of the connecting block.

[0009] In order to achieve the effect of driving the slide cylinder to slide on the slide rod, preferably, a slide cylinder is fixedly connected to one side of the lifting plate, a slide rod is inserted inside the slide cylinder, the slide rod is fixedly connected to the bottom of the top plate, and a vent hole is opened at the bottom of the slide cylinder.

[0010] To achieve the effect of switching between roller support and base plate support, preferably, the base plate has a through groove inside, the slide cylinder is inserted into the through groove, and the bottom of the slide cylinder is provided with rollers.

[0011] To achieve the effect of freely changing the configuration, preferably, a threaded column is fixedly connected to the top of the top plate, a counterweight is sleeved on the outside of the threaded column, a baffle is attached to the top of the counterweight, a threaded cylinder is fixedly connected to the top of the baffle, and the baffle and the threaded cylinder are inserted on the outside of the threaded column.

[0012] To achieve the effect of pushing and controlling, preferably, a handle is fixedly connected to the top of the top plate, and a controller is provided on the top of the top plate.

[0013] Compared with existing technologies, the advantages of this utility model are: It employs a stable support mechanism to switch between base plate stable support and roller-based movement, simplifying operation. The switching between the two modes is controlled by a single hydraulic telescopic rod, resulting in a simple structure, reduced risk of component failure, and improved device stability. Furthermore, the detachable counterweight allows for flexible adjustment of the counterweight as needed. Attached Figure Description

[0027] refer to Figure 1 and Figure 2 As shown, a threaded column 9 is fixedly connected to the top of the top plate 1. A counterweight 10 is sleeved on the outside of the threaded column 9. A baffle 11 is attached to the top of the counterweight 10. A threaded cylinder 12 is fixedly connected to the top of the baffle 11. The baffle 11 and the threaded cylinder 12 are inserted on the outside of the threaded column 9.

[0028] refer to Figure 1 and Figure 2 As shown, a handle 13 is fixedly connected to the top of the top plate 1, and a controller 14 is provided on the top of the top plate 1.

[0029] It should be noted that: connecting rod 2 is welded and fixed to the bottom of top plate 1 and the top of bottom plate 3 respectively. Connecting rod 2 is evenly distributed between top plate 1 and bottom plate 3. Hydraulic telescopic rod 41 is installed at the bottom of top plate 1 by bolts.

[0030] The working principle of the roadbed tamping and compaction device provided by this utility model is as follows:

[0031] In use, push handle 13 to move the device to the area requiring compaction. Controller 14 controls the retraction of hydraulic telescopic rod 41, which in turn drives connecting block 42 to raise lifting plate 43. Lifting plate 43 causes slide cylinder 44 to slide upwards along slide rod 45. Vent hole 46 balances the internal and external air pressure during slide cylinder 44's movement, reducing resistance. Slide cylinder 44 drives roller 48 upwards until base plate 3 fully contacts the ground. At this point, base plate 3 provides stable support for the device. After hydraulic rammer 7 is started, it drives rammer block 8 to compact the ground. The ground is compacted by tamping. The tamping block 8 is designed as a long strip perpendicular to the direction of movement, so that it can cover more tamping areas in one movement. Multiple counterweights 10 are fitted on the outside of the threaded column 9. The number of counterweights 10 can be increased or decreased as needed. The counterweights 10 are fixed by the threaded engagement of the threaded column 9, the baffle 11, and the threaded cylinder 12. After one tamping operation, the hydraulic telescopic rod 41 extends and eventually drives the roller 48 to descend and make full contact with the ground. After moving a suitable distance, the above process is repeated to compact the ground.
