Description

Technical Field

[0001] The invention relates to the technical field of roadbed construction, in particular to a soft soil roadbed compacting device for coastal municipal construction. Background Art

[0002] The coastal plains originated from shallow sea sediments. The soil is deep and sticky. Most of them are saturated normally compacted clay. The soil types are mostly silt, silty clay, and silty sub-clay. The main characteristics are: high natural water content, large natural porosity, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, and high disturbance.

[0003] Tamping, or tamping, originally involved the manual application of hard objects like stones to solidify the foundation during residential construction, typically performed by two or more people. Modern foundation tamping has been replaced by mechanical tamping, also known as electric tamping. This practice, often used in the construction industry, involves repeatedly dropping a heavy object onto the foundation or fill material to increase its density.

[0004] However, the compaction device currently used for roadbed has a relatively simple structure and can only perform single compaction, resulting in poor compaction effect, which affects the construction efficiency of soft soil roadbed. Summary of the Invention

[0008] A sliding opening is provided on one side of the operating box, a support plate is slidably connected to the sliding opening, a cavity is provided at one end of the support plate, a screw is rotatably connected to the cavity, a first gear is fixedly sleeved on the screw, a second gear meshing with the first gear is provided in the cavity, the second gear and the inner wall of the cavity are rotatably connected via a transmission rod, one end of the transmission rod passes through the inner wall of the cavity and is fixedly connected to a knob, the bottom of the screw passes through the inner wall of the cavity and is threadedly sleeved with a connecting plate, and the bottom of the connecting plate is fixedly connected to a hammer plate;

[0009] The support plate is located at the top of the operating box and is fixedly connected to a horizontal plate. The bottom of the horizontal plate is fixedly connected to a wedge plate. The bottom of the support plate is fixedly connected to two symmetrically arranged sliding sleeves. Sliders are slidably connected in the two sliding sleeves. The bottom of the slider is fixedly connected to a bearing rod fixedly connected to the bottom of the operating box. A spring is sleeved on the bearing rod, and both ends of the spring are fixedly connected to the slider and the bottom of the sliding sleeve respectively.

[0010] Preferably, the plurality of moving mechanisms are all universal self-locking wheels.

[0011] Preferably, the motor is a servo motor.

[0012] Preferably, a push handle is fixedly connected to one side outer wall of the operation box.

[0013] Preferably, a stabilizing rod is fixedly connected in the sliding opening, and the support plate is slidably sleeved on the stabilizing rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) In the present invention, the movement of the entire device is achieved through the moving mechanism on the bottom of the operating box. During operation, the starting motor drives the driving wheel on the output shaft to rotate. At this time, the driving wheel will use the connecting belt to realize the rotation of the driven wheel. At this time, the cam installed on the rotating rod will follow the rotation. The protruding end of the cam will press against the bottom of the horizontal plate to stretch the support plate to move. At this time, the sliding sleeve will compress the spring between the slider. When the cam is not in contact with the horizontal plate, the rebound force of the spring and the weight of the hammer plate itself will be used to return the support plate to its initial position, thereby realizing reciprocating hammering and compaction;

[0017] (2) In the present invention, the automatic reciprocating compacting mechanism is provided so that the roadbed compacting device can perform compaction freely. At the same time, the device is easy to operate and can perform compaction continuously, thereby improving the roadbed compaction effect.

[0027] In this embodiment, a sliding mouth is provided on one side of the operating box 1, and a support plate 9 is slidably connected to the sliding mouth for supporting the hammer plate 11. A cavity is provided at one end of the support plate 9, and a screw rod 20 is rotatably connected to the cavity. A first gear 21 is fixedly sleeved on the screw rod 20, and a second gear 22 meshing with the first gear 21 is provided in the cavity for driving the first gear 21 to rotate. The second gear 22 and the inner wall of the cavity are rotatably connected through a transmission rod 23. One end of the transmission rod 23 passes through the inner wall of the cavity and is fixedly connected to a knob 24 for driving the transmission rod 23 to rotate. The bottom of the screw rod 20 passes through the inner wall of the cavity and is threadedly sleeved with a connecting plate 10. The bottom of the connecting plate 10 is fixedly connected to the hammer plate 11 for compacting soft soil roadbed;

[0028] In this embodiment, one end of the screw rod 20 located in the connecting plate 10 is fixedly connected to a limit block 25 to prevent the screw rod 20 from falling out of the connecting plate 10. The bottom of the support plate 9 is connected to the hammer plate 11 by a plurality of symmetrically arranged telescopic rods 26 to prevent the hammer plate 11 from shaking. A fastening bolt 27 is threadedly inserted into one end of the knob 24. A plurality of fastening grooves corresponding to the fastening bolts 27 are arranged around the outer wall of the support plate 9 to facilitate the fixing of the knob 24.

[0029] In this embodiment, the support plate 9 is located at the top of the operating box 1 and is fixedly connected to a horizontal plate 12. The bottom of the horizontal plate 12 is fixedly connected to a wedge plate 13. The bottom of the support plate 9 is fixedly connected to two symmetrically arranged sliding sleeves 14. Sliders 15 are slidably connected in the two sliding sleeves 14. The bottom of the slider 15 is fixedly connected to a load-bearing rod 16 fixedly connected to the bottom of the operating box 1 for supporting the support plate 9. A spring 17 is sleeved on the load-bearing rod 16.
