[0062] Eccentric wheels 21 are rotatably arranged inside the rolling rollers 2. The two shaft ends of the eccentric wheels 21 are rotatably arranged in the shaft holes of the rolling rollers 2.

The connecting shaft 111 is fixedly connected with the shaft end of the incomplete gear 41.

[0064] Two scraping plates 17 are fixedly arranged at the bottom of the support 12, which are respectively used for cleaning the outer surfaces of the two rolling rollers 2. A towing frame 18 for connecting an external towing device is arranged on one side of the moving frame 1.

[0065] Principle and advantages of the soft soil foundation rolling and ramming device:

[0066] First, before ramming, connect the moving frame 1 with an external towing device through the towing frame 18. The external towing device uses mechanical equipment such as tractors and bulldozers in the prior art to drive the moving frame 1 to move on the soft soil foundation. During the moving process, the two rolling rollers 2 located at the bottom of the moving frame 1 are driven to rotate. After starting the driving device 13, the eccentric wheels 21 inside the rolling rollers 2 are driven by the driving device 13 at the top of the moving frame 1 to rotate at a high speed, so that the rolling rollers 2 vibrate and ram the soft soil foundation.

[0067] Meanwhile, the driving device 13 drives the lifting assembly 4 at the top of the support 12 to operate, causing the incomplete gear 41 in the lifting assembly 4 to rotate. When the incomplete gear 41 meshes with the toothed plate 43, the incomplete gear 41 drives the toothed plate 43 to slide upward outside the box body 14. After the toothed plate 43 slides a certain height, the teeth on the outside of the incomplete gear 41 cross over the toothed plate 43 and disengage. At this time, the toothless section of the incomplete gear 41 passes outside the toothed plate 43, causing the toothed plate 43 to lose the lifting force and automatically fall. Then, the column 45 inside the box body 14 is driven to continuously lift a certain height and then move downward in a free-fall manner. The impact generated by the free fall of the column 45 drives the connecting assembly 5 to automatically connect with the ramming block 32, enabling the column 45 to drive the ramming block 32 to continuously lift a certain height through the connecting assembly 5, and then generate an impact on the ramming plate 3 in a free-fall motion, realizing deep compaction of the soft soil foundation between the two rolling rollers 2. At the same time, the two rolling rollers 2 vibrate and compact the foundation on both sides simultaneously, improving the compaction effect on the soft soil foundation;

[0068] During the movement, the outer sides of the two rolling rollers 2 are respectively cleaned by the two scraping plates 17 at the bottom of the support 12, and the ramming plate 3 is inclined upward on one side in the forward direction. When encountering a ramming step, the ramming plate 3 can move upward under the action of the inclined side to cross the height difference. Therefore, it can move forward along the foundation under the drive of the moving frame 1 without repeated lifting. After the ramming is completed, the electromagnetic suction ring 16 on the outside of the fixed cylinder 15 is energized to suck the adsorption ring 37 upward, causing the adsorption ring 37 to drive the ramming plate 3 away from the ground, ensuring smooth movement.

[0069] Its advantages are as follows: By arranging two rolling rollers 2 at the bottom of the moving frame 1, when the rolling rollers 2 are driven to rotate by traction, the driving device 13 simultaneously drives the rolling rollers 2 to achieve the vibration compaction effect, and the driving device 13 simultaneously drives the ramming plate 3 between the two rolling rollers 2 to perform impact compaction, realizing deep compaction of the soft soil foundation. And under the drive of the moving frame 1 and the rolling rollers 2, the effect of ramming while moving the ramming plate 3 can be achieved to ensure the compaction efficiency of the soft soil foundation; By setting the connecting assembly 5 to detachably connect the column 45 and the ramming block 32, when the column 45 moves in a free-fall motion, the connecting assembly 5 is automatically connected to the ramming block 32 by relying on the impact force, and the ramming block 32 is automatically released after being lifted to different heights, enabling the ramming block 32 to generate an impact on the ramming plate 3 in a free-fall motion, so as to adjust the lifting height of the ramming block 32 according to the compaction requirements of the soft soil foundation and adapt to different compaction requirements.

[0070] During the compaction process of the connection component 5 and the limit plate 6 in the soft soil foundation rolling and compaction device of the present application, first, according to the requirements of soft soil foundation compaction, the vibration frequency of the rolling roller 2 and the lifting height of the compaction block 32 are adjusted. When adjusting the vibration frequency of the rolling roller 2, only the driving speed of the driving device 13 for the eccentric wheel 21 needs to be adjusted. When adjusting the lifting height of the compaction block 32, the lifting plate 62 is driven to move up and down outside the scale bar 114 by rotating the adjusting screw rod 63 at the top of the box body 14, so that the lifting plate 62 drives the limit plate 6 to be at different heights inside the box body 14 through the slide rod 61. The specific height can be observed through the scale bar 114.

[0071] On the basis of the above adjustments, when the column 45 drives the connection component 5 to move downward in free fall, the insertion column 52 at the bottom of the connection column 51 laterally squeezes the block 34 inside the insertion hole 331 through the first conical inclined surface 521 on the outside, so that the block 34 squeezes the support spring 35 and moves into the side wall of the connection block 33. Until the insertion column 52 passes over the block 34, the block 34 automatically resets to the top of the insertion column 52 under the action of the support spring 35. At this time, the sleeve 53 outside the connection column 51 moves away from the top of the insertion column 52 under the action of the adsorbent 54, and when the column 45 moves upward, it can drive the compaction block 32 to move upward inside the fixed cylinder 15;

[0072] As the height of the connection column 51 increases, when the pressure plate 532 outside the sleeve 53 reaches the bottom of the limit plate 6, under the extrusion of the limit plate 6, it overcomes the adsorption force of the adsorbent 54 on the pressure plate 532, and then presses the sleeve 53 into the inside of the receiving groove 522. Before the sleeve 53 is pressed into the inside of the receiving groove 522, the sleeve 53 cooperates with the block 34 through the second conical inclined surface 531 at the bottom to laterally squeeze the block 34 again, so that the block 34 gradually disengages from the top of the insertion column 52. When the second conical inclined surface 531 is completely received and accommodated inside the receiving groove 522, the second conical inclined surface 531 squeezes the block 34 to completely disengage from the top of the insertion column 52. At this time, the compaction block 32 drives the block 34 inside the connection block 33 to move downward by its own gravity, so that the compaction block 32 impacts the compaction plate 3 by free fall motion, and the compaction plate 3 deeply compacts the soft soil foundation.

[0073] It should be noted that the above compaction method has the following advantages:

[0074] Advantage one, by rotating the adjusting screw rod 63, the height of the limit plate 6 can be adjusted, so that the limit plate 6 limits the lifting height of the compaction block 32, indirectly realizing the adjustment of the lifting height of the compaction block 32 to facilitate adaptation to different compaction requirements.

[0075] Advantage two: By providing a plug post 52 at the bottom of the connecting post 51 to form a snap connection with the clamping block 34, the plug post 52 automatically snaps into connection with the clamping block 34 by relying on the impact force generated downward by the upright post 45, so as to facilitate the automatic and rapid connection of the upright post 45 and the ramming block 32.

[0076] Advantage three: By slidably providing a sleeve 53 outside the connecting post 51, when the ramming block 32 is lifted to a certain height, the pressing plate 532 on the outside of the sleeve 53 reaches the bottom of the limiting plate 6. At this time, the upright post 45 continues to move upward. Relying on the power when the upright post 45 is lifted, the limiting plate 6 pushes the sleeve 53 to slide downward to disengage the lateral clamping block 34 from the top of the plug post 52, realizing the automatic disconnection of the connection between the ramming block 32 and the upright post 45.

[0077] Advantage four: By providing an adsorbent 54 to adsorb the pressing plate 532, during the process of the plug post 52 engaging with the clamping block 34, the sleeve 53 moves away from the top of the plug post 52 to leave a clamping space for the clamping block 34. When it is necessary to release the snap connection of the clamping block 34, the limiting plate 6 is used to squeeze the pressing plate 532 to break through the adsorption force of the adsorbent 54, so that the sleeve 53 can achieve the effect of moving up and down respectively in the connected and disconnected states of the plug post 52 and the clamping block 34.

[0078] Advantage five: By providing an incomplete gear 41 to drive a toothed plate 43 to drive the upright post 45 to lift a fixed height, the upright post 45 can drive the connecting assembly 5 to generate a fixed impact force downward each time, so as to ensure that the connecting assembly 5 can be automatically docked with the connecting block 33. At the same time, it serves as a power source to lift the ramming block 32 upward without affecting the lifting height of the ramming block 32.
