Description

Technical Field

[0001] The present invention relates to the technical field of soft foundation ramming, and specifically to a silt solidification ramming device. Background Technique

[0002] Soft subgrade soil refers to soil mainly composed of saturated soft clay, silt or peat soil, organic matter soil and peat in the soil subgrade, which has characteristics such as high natural water content, large void ratio, low permeability, high compressibility, low shear strength and bearing capacity. For soft foundation soil in the foundation, generally methods such as replacing soil, sand cushion, and ramming are adopted to improve the foundation stability and bearing capacity.

[0003] The existing publicly disclosed patent CN112281802B discloses a soft foundation treatment device and treatment method. The eccentric wheel disc is rotationally connected in the fixed ring, and the upper end of the fixed ring is vertically slidably connected to the fixed cross frame through the second connecting rod. When the eccentric wheel disc rotates, due to its eccentric rotation, it can drive the fixed ring to perform reciprocating motion in the vertical direction. A first connecting rod is fixedly connected to the lower end of the fixed ring, a connecting seat is fixedly connected to the bottom end of the first connecting rod, and a ramming plate is fixedly connected to the bottom end of the connecting seat through a buffer spring. When the fixed ring performs reciprocating motion in the vertical direction, it can drive the ramming plate at the bottom to ram the bottom surface of the soft foundation. At the same time, an auxiliary spring is also sleeved on the first connecting rod. When the fixed ring moves upward, it will squeeze the auxiliary spring, and when the fixed ring starts to move downward after moving to a fixed point, due to the restoring force of the auxiliary spring, it can push the fixed ring downward, thereby providing a greater downward force to the ramming plate at the bottom, and can better play the role of ramming the soft foundation.

[0004] In the prior art, dynamic compaction of soft soil foundation should be carried out according to the principle of low energy level, few blows, multiple passes, and first low energy level and then high energy level. Usually, 2 passes or 4 passes of ramming are carried out, and the single-blow ramming energy should be increased from small to large. However, during the use of the above device, the upward movement distance of the ramming plate driven by the eccentric wheel disc is fixed and non-adjustable, resulting in a single and fixed force for the ramming plate to ram the ground. The device is inconvenient to adjust according to the actual situation, so the limitations of the above device in actual use are relatively large. Summary of the Invention

The spring one 205 can drive the connecting ring 203 to move downward, and the two ends of the spring one 205 are respectively in movable abutment with the frame 1 and the connecting ring 203. An annular groove 206 is formed on the inner wall of the connecting ring 203, and the annular groove 206 can prevent the lubricating oil from flowing out.

[0033] Please refer to Figure 5 , the driving mechanism 3 includes a rotating shaft 301 rotatably connected to the frame 1 through a bearing. A plurality of equally spaced driving rings 302 are fixedly sleeved outside the rotating shaft 301, and the rotating shaft 301 is far from the center of the driving ring 302. The connection method between the driving ring 302 and the connecting ring 203 is still in contact. An activity block 303 is movably embedded inside the driving ring 302, and the activity block 303 can move up and down inside the driving ring 302 through an embedding groove 306. A support plate 304 is fixedly connected to the lower end of the activity block 303.

[0034] Please refer to Figure 2 , Figure 4 , two symmetrically distributed springs two 305 are fixedly installed at the upper end of the support plate 304 outside the activity block 303, and the upper ends of the springs two 305 are fixedly connected to the driving ring 302. An overflow groove 307 is formed inside the activity block 303, and the lubricating oil flows out from inside the activity block 303 through the overflow groove 307. The shape of the overflow groove 307 is "U" shaped. One end of the rotating shaft 301 is fixedly connected with a driving motor 308, and the driving motor 308 is fixedly connected to the frame 1. A ball 309 is movably embedded at the center of the lower end of the support plate 304.

[0035] Please refer to Figure 4 , Figure 5 , the adjusting structure 4 includes a hollow rod 401 movably embedded inside the rotating shaft 301 and capable of moving left and right. The lower end of the ball 309 is in movable abutment with a pressing block 402. The cross-sectional shape of the pressing block 402 is a right triangle. The ball 309 can reduce the frictional resistance between the support plate 304 and the pressing block 402. A positioning rod one 403 is fixedly installed between the hollow rod 401 and the pressing block 402. A positioning rod two 404 is also fixedly installed between the hollow rod 401 and the pressing block 402, and the positioning rod two 404 is a hollow structure. Both the positioning rod one 403 and the positioning rod two 404 are in sliding contact with the rotating shaft 301 and the driving ring 302 through a limiting straight groove 408.

[0036] Please refer to Figure 6 ,Figure 7 , a flow groove 405 is formed inside the extrusion block 402, and the flow groove 405 is communicated with the hollow rod 401 through the second positioning rod 404. A connecting seat 406 is sleeved outside one end of the hollow rod 401 far away from the driving motor 308, and the hollow rod 401 is rotationally connected with the connecting seat 406 through a bearing. Two symmetrically distributed electric push rods 407 are fixedly installed on one side of the connecting seat 406 close to the frame 1. The electric push rod 407 can drive the hollow rod 401 to move inside the rotating shaft 301, and one end of the electric push rod 407 far away from the connecting seat 406 is fixedly connected with the frame 1.

[0037] Working principle: When compacting the silt foundation, the driving motor 308 drives the rotating shaft 301 to rotate, and the rotating shaft 301 drives a plurality of driving rings 302 to rotate eccentrically. During the rotation of the driving ring 302, the farthest edge of the driving ring 302 from the rotating shaft 301 slides in contact with the inner wall of the connecting ring 203. When the farthest edge of the driving ring 302 from the rotating shaft 301 rotates to the upper end, the driving ring 302 drives the compaction plate 201 to move upward through the connecting ring 203. At this time, the first spring 205 is compressed. When the farthest edge of the driving ring 302 from the rotating shaft 301 moves to the lower end, the compaction plate 201 also moves downward, and under the driving of the compression elastic force of the first spring 205, the downward pressure of the compaction plate 201 will increase, and the silt foundation can be compacted;

[0038] When it is necessary to change the compaction force of the compaction plate 201 subsequently, the operator controls the electric push rod 407 to operate. The electric push rod 407 drives the hollow rod 401 and a plurality of extrusion blocks 402 to move to the right through the connecting seat 406. During the rightward movement of the extrusion block 402, the hypotenuse of the extrusion block 402 drives the ball 309 and the movable block 303 to move upward inside the driving ring 302, changing the farthest edge of the driving ring 302 from the rotating shaft 301. At this time, the distance of the up and down movement of the compaction plate 201 will increase accordingly. Within a certain range, the compression degree of the first spring 205 is also changed, so as to facilitate the adjustment of the force of the compaction plate 201 to compact the ground, making the device conform to the compaction principle of soft soil foundation.

[0039] Embodiment 2: Please refer to Figure 2 , Figure 7, this embodiment further elaborates on the first embodiment. The lubrication structure 5 includes two bent connecting rods 501 that are symmetrically distributed and fixedly embedded in the lower end of the connecting seat 406. One end of the bent connecting rod 501 away from the connecting seat 406 is fixedly connected to a pressing plate 502. A rectangular airbag 503 is fixedly adhered to one side of the pressing plate 502 away from the bent connecting rod 501, and the rectangular airbag 503 is fixedly embedded in the side wall of the frame 1. One end of the hollow rod 401 close to the connecting seat 406 is fixedly connected to a rotary joint 504. A conduit 505 is fixedly installed between the rotary joint 504 and the rectangular airbag 503. A round hole for avoiding the conduit 505 is provided on the pressing plate 502.

[0040] Please refer to Figure 6 , Figure 7 , a conduit 506 is installed on one side of the rectangular airbag 503 away from the pressing plate 502. Check valves 507 are fixedly installed between the conduit 505, the conduit 506 and the rectangular airbag 503. One end of the conduit 506 away from the rectangular airbag 503 is fixedly connected to a storage barrel 508. The storage barrel 508 is fixedly connected to the frame 1. Lubricating oil is stored in the storage barrel 508. A conduit 509 is fixedly installed between the extrusion block 402 and the movable block 303, and the overflow groove 307 is interconnected with the flow groove 405 through the conduit 509.

[0041] In this embodiment: When the electric push rod 407 drives the plurality of extrusion blocks 402 to move to the right, the pressing plate 502 moves accordingly under the action of the bent connecting rod 501. When the pressing plate 502 moves to the right, it will squeeze the rectangular airbag 503. Under the action of the two check valves 507, the quantitative lubricating oil in the rectangular airbag 503 will enter the "U"-shaped overflow groove 307 inside the movable block 303 through the conduit 505 and the conduit 509, etc. When the rotating shaft 301 drives the movable block 303 to rotate, the lubricating oil in the overflow groove 307 will flow between the movable block 303 and the connecting ring 203 to lubricate the movable block 303 and the connecting ring 203, reducing the frictional resistance between the movable block 303 and the connecting ring 203, thereby reducing the wear of the device;

[0042] When the electric push rod 407 drives the extrusion block 402 to move leftward and reset, the pressure acting on the rectangular airbag 503 disappears, and the rectangular airbag 503 will gradually recover as the pressing plate 502 moves. During the recovery process of the rectangular airbag 503, the quantitative lubricating oil in the storage barrel 508 will enter the rectangular airbag 503. When the rectangular airbag 503 is completely recovered, the rectangular airbag 503 is in a full liquid state.

[0043] Embodiment Three: Please refer to Figure 8, this embodiment further elaborates on Embodiment 2. A plurality of rubber valves 6 evenly distributed at equal intervals in a circle are fixedly embedded at one end of the third catheter 509 inside the movable block 303. The plurality of rubber valves 6 are in movable contact with each other end to end, and the plurality of rubber valves 6 can be opened under the drive of liquid pressure.

[0044] In this embodiment: when no pressure acts on the rectangular airbag 503, the plurality of rubber valves 6 are in a closed state. At this time, the rectangular airbag 503, the first catheter 505, the hollow rod 401, the second positioning rod 404, the flow groove 405, and the third catheter 509 are all filled with liquid. When the pressing plate 502 squeezes the rectangular airbag 503, the quantitative lubricating oil in the rectangular airbag 503 will enter the first catheter 505. The plurality of rubber valves 6 will open under the action of liquid pressure, and the quantitative liquid will enter the overflow groove 307, which is beneficial to evenly distribute the lubricating oil extruded from the rectangular airbag 503 into the overflow grooves 307 of each movable block 303. After the third catheter 509 is depressurized, the plurality of rubber valves 6 will close again, which can effectively prevent the lubricating oil in the overflow groove 307 from flowing back.
