The first bearing seat 112 is fixedly arranged on the top of the support 12, and the connecting shaft 111 is fixedly connected to the shaft end of the incomplete gear 41.

[0032] Two scrapers 17 are fixedly provided at the bottom of the support 12 for cleaning the outer surfaces of the two rolling rollers 2 respectively. A traction frame 18 for connecting an external traction device is provided at one side of the mobile frame 1.

[0033] Principles and advantages of soft soil foundation rolling compaction device: First, before compaction, the mobile frame 1 is connected to an external traction device through a traction frame 18. The external traction device adopts mechanical equipment such as tractors and bulldozers in the prior art to drive the mobile frame 1 to move on the soft soil foundation. During the movement, the two rolling rollers 2 at the bottom of the mobile frame 1 are pulled and rotated. After the driving device 13 is started, the eccentric wheel 21 inside the rolling roller 2 is driven to rotate at a high speed through the driving device 13 at the top of the mobile frame 1, so that the rolling roller 2 vibrates and compacts the soft soil foundation; At the same time, the driving device 13 drives the lifting assembly 4 on the top of the support 12 to operate, so that the incomplete gear 41 in the lifting assembly 4 rotates. When the incomplete gear 41 is meshed with the tooth plate 43, the incomplete gear 41 drives the tooth plate 43 to slide upward on the outside of the box body 14. When the tooth plate 43 slides to a certain height, the teeth on the outside of the incomplete gear 41 pass over the tooth plate 43 and disengage. At this time, the toothless section of the incomplete gear 41 passes the outside of the tooth plate 43, causing the tooth plate 43 to lose its lifting force and automatically fall down, thereby driving the box body 14. The inner column 45 is continuously lifted to a certain height and then moves downward in a free-falling manner. The impact generated by the free-fall of the column 45 drives the connecting assembly 5 to automatically connect with the tamping block 32, so that the column 45 drives the tamping block 32 to continuously lift to a certain height through the connecting assembly 5, and then impacts the tamping plate 3 in a free-falling motion, so as to achieve deep tamping of the soft soil foundation between the two rolling rollers 2. At the same time, the two rolling rollers 2 simultaneously vibrate and tamp the foundations on both sides, thereby improving the tamping effect of the soft soil foundation. During the movement, the outer sides of the two rolling rollers 2 are cleaned respectively by the two scrapers 17 at the bottom of the support 12, and the tamping plate 3 is arranged on one side of the forward direction and tilted upward. When encountering a tamping step, the tamping plate 3 can be moved upward to overcome the height difference under the action of the inclined side. Therefore, it can move forward along the foundation driven by the moving frame 1 without repeated lifting. After the tamping is completed, the electromagnetic suction ring 16 on the outside of the fixed cylinder 15 is energized to adsorb the adsorption ring 37 upward, so that the adsorption ring 37 drives the tamping plate 3 away from the ground to ensure smooth movement.

[0034] Its advantages are that two rolling rollers 2 are arranged at the bottom of the mobile frame 1. When the rolling rollers 2 are pulled and rotated, the driving device 13 simultaneously drives the rolling rollers 2 to achieve a vibration compaction effect, and the driving device 13 simultaneously drives the compaction plate 3 between the two rolling rollers 2 to perform impact compaction, thereby achieving deep compaction of the soft soil foundation. Moreover, under the drive of the mobile frame 1 and the rolling rollers 2, the compaction plate 3 can achieve a compaction effect while moving, so as to ensure the compaction efficiency of the soft soil foundation. By setting a connecting component 5, the column 45 is detachably connected to the compaction block 32, so that when the column 45 moves in free fall, the connecting component 5 is automatically connected to the compaction block 32 by the impact force, and the compaction block 32 is automatically released after being lifted to different heights, so that the compaction block 32 impacts the compaction plate 3 with free fall motion, so as to adjust the lifting height of the compaction block 32 according to the compaction requirements of the soft soil foundation, so as to adapt to different compaction requirements.

[0035] During the compaction process, the connecting assembly 5 and the limit plate 6 in the soft soil foundation rolling and compacting device of the present application first adjust the vibration frequency of the rolling roller 2 and the lifting height of the compacting block 32 according to the compaction requirements of the soft soil foundation. When adjusting the vibration frequency of the rolling roller 2, it is only necessary to adjust the driving speed of the driving device 13 on the eccentric wheel 21. When adjusting the lifting height of the compacting block 32, the lifting plate 62 is driven to move up and down on the outside of the ruler 114 by rotating the adjusting screw 63 on the top of the box body 14, so that the lifting plate 62 drives the limit plate 6 through the slide rod 61 to be located at different heights inside the box body 14, and the specific height can be observed through the ruler 114.

[0036] On the basis of the above adjustment, when the column 45 drives the connection assembly 5 to move downward in free fall, the plug-in column 52 at the bottom of the connection column 51 squeezes the block 34 inside the plug hole 331 laterally through the first conical inclined surface 521 on the outside, so that the block 34 squeezes the support spring 35 and moves inwardly toward the side wall of the connection block 33, until the plug-in column 52 passes over the block 34, and the block 34 automatically resets to the top of the plug-in column 52 under the action of the support spring 35. At this time, the sleeve 53 on the outside of the connection column 51 is away from the top of the plug-in column 52 under the action of the adsorption member 54, and the column 45 can drive the tamping block 32 to move upward on the inner side of the fixed tube 15 when it moves upward; As the height of the connecting column 51 increases, when the pressure plate 532 on the outside of the sleeve 53 reaches the bottom of the limit plate 6, the adsorption force of the adsorption member 54 on the pressure plate 532 is overcome under the extrusion of the limit plate 6, and then the sleeve 53 is pressed downward into the interior of the accommodating groove 522. Before the sleeve 53 is pressed into the inner side of the accommodating groove 522, the sleeve 53 cooperates with the block 34 through the second conical slope 531 at the bottom to extrude the block 34 laterally again, so that the block 34 gradually separates from the top of the plug-in column 52. When the second conical slope 531 is fully cooperated and accommodated in the inner side of the accommodating groove 522, the second conical slope 531 squeezes the block 34 to completely separate from the top of the plug-in column 52. At this time, the tamping block 32 relies on its own gravity to drive the block 34 on the inside of the connecting block 33 to move downward, so that the tamping block 32 relies on the free fall motion to impact the tamping plate 3, so that the tamping plate 3 deeply compacts the soft soil foundation.

[0037] It is worth mentioning that the above compaction method has the following advantages: Advantage 1: The height of the limit plate 6 can be adjusted by rotating the adjusting screw rod 63, so that the limit plate 6 limits the lifting height of the tamping block 32, and indirectly realizes the adjustment of the lifting height of the tamping block 32 to adapt to different tamping requirements.

[0038] Advantage 2: By setting a plug-in column 52 at the bottom of the connecting column 51 to form a snap connection with the block 34, the plug-in column 52 can automatically snap-connect with the block 34 by relying on the downward impact force generated by the column 45, so as to automatically and quickly connect the column 45 with the tamping block 32.

[0039] Advantage three, by sliding the sleeve 53 on the outside of the connecting column 51, when the tamping block 32 is lifted to a certain height, the pressure plate 532 on the outside of the sleeve 53 reaches the bottom of the limit plate 6, and the column 45 continues to move upward. Relying on the power when the column 45 is lifted, the limit plate 6 pushes the sleeve 53 to slide downward and the lateral block 34 is separated from the top of the plug-in column 52, thereby automatically releasing the connection between the tamping block 32 and the column 45.

[0040] Advantage four, by setting the adsorption member 54 to adsorb the pressure plate 532, when the plug-in column 52 is engaged with the block 34, the sleeve 53 is away from the top of the plug-in column 52 to leave an engagement space for the block 34. When the engagement connection of the block 34 needs to be released, the pressure plate 532 is squeezed by the limit plate 6 to break through the adsorption force of the adsorption member 54, so that the sleeve 53 can achieve the effect of moving up and down when the plug-in column 52 is connected and disconnected with the block 34.

[0041] Advantage five, by setting the incomplete gear 41 to drive the tooth plate 43 to drive the column 45 to lift to a fixed height, the column 45 can drive the connecting component 5 downward to generate a fixed impact force each time, so as to ensure that the connecting component 5 can be automatically docked with the connecting block 33, and at the same time serve as a power source to lift the tamping block 32 upward without affecting the lifting height of the tamping block 32.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
