DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the invention can be implemented in many different ways as defined and covered by the claims.

[0030] See Figure 1A preloading soft foundation treatment equipment includes a bracket 1, a lifting mechanism 2, a disc-shaped shell 3, a driving mechanism 4, a material moving mechanism 5 and a compacting mechanism 6. Two brackets 1 are symmetrically arranged on the left and right. The upper horizontal sections of the two brackets 1 are commonly connected to the lifting mechanism 2. The lower end of the lifting mechanism 2 is connected to the disc-shaped shell 3. An opening is provided below the disc-shaped shell 3 and the driving mechanism 4 is connected to the disc-shaped shell 3. The driving mechanism 4 is connected to the material moving mechanism 5 below, and the material moving mechanism 5 is connected to the compacting mechanism 6.

[0031] During the specific work, after a detailed geological survey of the working area, the preloaded soft foundation treatment equipment is moved as a whole to the working area through external lifting equipment, and the bracket 1 is fixedly installed at the edge of the working area. Then the driving mechanism 4 is started first, and then the lifting mechanism 2 drives the disc-shaped shell 3, the material moving mechanism 5 and the compacting mechanism 6 to descend synchronously. During the descent of the material moving mechanism 5, the soil below will be loosened first, and then the loosened soil will be discharged upward to the outside of the working area. After the material moving mechanism 5 has been operating for a period of time, a foundation pit can be excavated in the working area.

[0032] When the excavation of the foundation pit is completed, the disc-shaped shell 3, the material moving mechanism 5 and the tamping mechanism 6 are synchronously raised and moved out of the foundation pit through the lifting mechanism 2, and then the driving mechanism 4 is closed and the material moving mechanism 5 is cleaned, and then filling materials such as sand and gravel are put into the material moving mechanism 5, and then the driving mechanism 4 is started again and made to run in reverse, and then the lower end of the material moving mechanism 5 is made to enter the foundation pit through the lifting mechanism 2, and then the material moving mechanism 5 is driven slowly upward for a section through the lifting mechanism 2, and the filling material is evenly sprinkled to the bottom of the foundation pit through the material moving mechanism 5. While sprinkling the filling material, the tamping mechanism 6 is started to compact the filling material, so as to achieve the effect of layered filling and layered compaction.

[0033] See Figure 1 and Figure 2 The lifting mechanism 2 includes a top frame 21, a movable seat 22, a fixed seat 23, a connecting plate 24 and a lifting assembly 25. The two brackets 1 are located between the upper horizontal sections and are symmetrically fixedly connected to the two top frames 21. The lower ends of the top frames 21 are symmetrically slidably connected to the two movable seats 22. Four fixed seats 23 are fixedly connected to the disc-shaped shell 3 in a matrix arrangement. The fixed seats 23 and the movable seats 22, which are located on the same straight line and close to each other, are hingedly connected by a connecting plate 24. The movable seat 22 and the top frame 21 are jointly connected with a lifting assembly 25.

[0034] See Figure 1 and Figure 2The lifting assembly 25 includes a hanging rod 251, a connecting rod 252 and a hydraulic cylinder 253. Two hanging rods 251 are fixedly connected symmetrically between the two top frames 21. The two movable seats 22 located in the same straight line front and back are fixedly connected by a connecting rod 252. The hydraulic cylinder 253 is hinged on the hanging rod 251 and the connecting rod 252.

[0035] During specific operation, in the initial state, the piston rods of the two hydraulic cylinders 253 are in an extended state, and the hanging rod 251 and the connecting rod 252 are also far away from each other, and then the two movable seats 22 located on the same top frame 21 are far away from each other, and the upward angle between the two symmetrical connecting plates 24 is large, so that the disc-shaped shell 3, the driving mechanism 4, the material moving mechanism 5 and the tamping mechanism 6 can be hoisted to a certain height. When the disc-shaped shell 3, the driving mechanism 4, the material moving mechanism 5 and the tamping mechanism 6 need to be lowered, the piston rods of the two hydraulic cylinders 253 are retracted at the same time to make the two movable seats 22 located on the same top frame 21 approach synchronously, and then the upward angle between the two symmetrical connecting plates 24 can be reduced, so that the disc-shaped shell 3, the driving mechanism 4, the material moving mechanism 5 and the tamping mechanism 6 can be synchronously lowered.

[0036] See Figure 3 and Figure 5 The driving mechanism 4 includes a bidirectional reduction motor 41, a circular plate 42, a ring plate 43, a rotating shaft 44 and a rotating assembly 45. The bidirectional reduction motor 41 is fixedly connected to the upper end surface of the disc-shaped shell 3. The driving shaft of the bidirectional reduction motor 41 passes through the disc-shaped shell 3 and is rotatably connected to the circular plate 42. A ring plate 43 is rotatably sleeved on the outer side of the circular plate 42. The outer side of the ring plate 43 is rotatably connected to the disc-shaped shell 3. Three rotating shafts 44 are circumferentially passed through the upper and lower sides of the ring plate 43 and are rotatably connected. The upper ends of the three rotating shafts 44 are located in the disc-shaped shell 3 and are commonly connected to the rotating assembly 45. The lower ends of the three rotating shafts 44 are commonly connected to the material moving mechanism 5.

[0037] See Figure 3 The rotating assembly 45 includes a central gear 451, planetary gears 452 and an inner ring gear 453. The planetary gears 452 are fixedly sleeved on the upper end of the rotating shaft 44. The three planetary gears 452 are commonly meshed and connected with the central gear 451. The central gear 451 is fixedly sleeved on the driving shaft of the bidirectional reduction motor 41. The outer sides of the three planetary gears 452 are commonly meshed and connected with the inner ring gear 453. The inner ring gear 453 is fixedly connected to the inside of the disc-shaped housing 3.

[0038] See Figure 3 and Figure 5The material moving mechanism 5 includes a connecting frame 51, a soil discharge pipe 52, a spiral conveying blade 53 and a collecting plate 54. The connecting frame 51 is rotatably sleeved on the rotating shaft 44, and the external fixed sleeve of the connecting frame 51 is provided with a soil discharge pipe 52. The rotating shaft 44 is fixedly connected to the spiral conveying blade 53 at the part located inside the soil discharge pipe 52. The top ends of the three soil discharge pipes 52 are commonly fixedly connected to the collecting plate 54, and the collecting plate 54 is connected to the tamping mechanism 6.

[0039] During specific operation, the bidirectional reduction motor 41 drives the center gear 451 to rotate synchronously. Under the joint action of the center gear 451 and the inner ring gear 453, the three planetary gears 452 rotate along the periphery of the center gear 451 while rotating. The rotation of the planetary gears 452 drives the rotating shaft 44 and the spiral conveying blades 53 to rotate synchronously, and then the soil loosened by the tamping mechanism 6 is transported upward along the soil discharge pipe 52 to the collecting tray 54. The revolution of the planetary gears 452 drives the ring plate 43 to rotate synchronously through the rotating shaft 44, and then drives the connecting frame 51, the soil discharge pipe 52, the collecting tray 54 and the tamping mechanism 6 to rotate synchronously.

[0040] See Figure 3-Figure 5 The tamping mechanism 6 includes a protective shell 61, an opening and closing assembly 62, a pressure plate 63, a traction assembly 64 and a deflector plate 65. The protective shell 61 is fixedly connected to the center of the upper end surface of the aggregate tray 54. The traction assembly 64 is connected to the protective shell 61. The lower ends of the three soil discharge pipes 52 are slidingly sleeved with a pressure plate 63. The lower end of the traction assembly 64 passes through the aggregate tray 54 and is fixedly connected to the pressure plate 63. The lower end surface of the pressure plate 63 is connected to three opening and closing assemblies 62 that cooperate with the pressure plate 63. The center of the lower end surface of the pressure plate 63 is connected to a deflector plate 65 through threads.

[0041] See Figure 5 、 Figure 7 and Figure 8 The opening and closing assembly 62 includes a ring seat 621, a mounting rod 622, a semicircular baffle 623, a torsion spring 624 and a notch 625. The lower end surface of the pressure plate 63 is provided with an annular groove at the edge of the soil discharge pipe 52. The ring seat 621 is fixedly connected to the annular groove. The inner wall of the ring seat 621 is fixedly connected to the mounting rod 622, which coincides with the diameter of the ring seat 621. Two semicircular baffles 623 are rotatably connected to the mounting rod 622. The two semicircular baffles are assembled to form a circular baffle that cooperates with the ring seat 621. Two circular rings are fixedly sleeved on the mounting rod 622. The two semicircular baffles 623 are connected to the circular ring by a torsion spring 624. The lower end surface of the rotating shaft 44 is provided with a notch 625 that cooperates with the semicircular baffle 623.

[0042] When the excavation is completed, the excavator 65 is manually removed to avoid obstruction of the subsequent compaction of the filling material by the pressure plate 63.

[0043] See Figure 4 and Figure 6 The traction assembly 64 includes a mounting plate 641, a connecting column 642, a lifting module 643, a U-shaped rod 644, a connecting rod 645, a lifting rod 646 and an acceleration module 647. The mounting plate 641 is fixedly connected to the upper end surface of the collecting tray 54 with two symmetrical connections on the left and right sides. The end surfaces of the two mounting plates 641 are symmetrically fixedly connected to the connecting column 642 at the upper position. The two connecting columns 642 are connected to the U-shaped rod 644 on the right side. The connecting column 642 is connected to a lifting module 643 that cooperates with the U-shaped rod 644. A connecting rod 645 is fixedly sleeved on the horizontal end of the U-shaped rod 644. A clearance groove extending in the front-to-back direction is opened at the center of the collecting tray 54. The lower end of the connecting rod 645 passes through the clearance groove and is rotatably connected to the lifting rod 646. The lower end of the lifting rod 646 is fixedly connected to the pressure plate 63. The three soil discharge pipes 52 and the lifting rod 646 are commonly connected to the acceleration module 647.

[0044] See Figure 6 The lifting module 643 includes a crank 6431, a columnar block 6432 and a drive motor 6433. The left end of the right mounting column is fixedly sleeved with a crank 6431. The right end face of the crank 6431 is fixedly connected with a columnar block 6432 that cooperates with the U-shaped rod 644. The right end of the right mounting column is fixedly connected with a drive motor 6433. The drive motor 6433 is fixedly connected to the protective shell 61, and the drive shaft of the drive motor 6433 is locked by a ratchet pawl mechanism connected to the right mounting plate 641.

[0045] See Figure 4 and Figure 5The acceleration module 647 includes a limit frame 6471 and a force storage spring 6472. The three soil discharge pipes 52 are fixedly sleeved with a limit frame 6471 at a position below the aggregate tray 54. The limit frame 6471 is slidingly connected to the lifting rod 646, and the limit frame 6471 is connected to the pressure plate 63 through the force storage spring 6472.

[0046] During specific operation, in the initial state, the right connecting column 642 and the rocker handle 6431 are in a locked static state under the action of the ratchet pawl mechanism, the U-shaped rod 644 opens downward and its right vertical section overlaps the column block 6432, the storage spring 6472 is in a compressed state, the pressure plate 63 is mounted on the soil discharge pipe 52, and the two semicircular baffles 623 are in the slot 625 and are in a closed state.

[0047] When the excavation of the foundation pit is completed and filling is required, the filling material is first placed in the collecting tray 54, and then the bidirectional reduction motor 41 is started, and the rotating shaft 44 of the bidirectional reduction motor 41 is rotated in the opposite direction to that when the foundation pit is excavated, and then the spiral conveying blades 53 can convey and sprinkle the filling material to the bottom of the foundation pit.

[0048] While spreading the filling material, start the drive motor 6433, and the right connecting column 642 is driven to rotate counterclockwise by the drive motor 6433, and then the crank handle 6431 is driven to rotate counterclockwise synchronously. When the crank handle 6431 rotates counterclockwise, the U-shaped rod 644 is driven to rotate counterclockwise through the column block 6432. During the counterclockwise rotation of the U-shaped rod 644, when its horizontal section passes the highest point, the U-shaped rod 644 loses support at the rear, and the U-shaped rod 644 rotates counterclockwise at a faster speed under the action of the gravity of the connecting rod 645, the lifting rod 646 and the pressure plate 63 and the action of the storage spring 6472, and then the connecting rod 645 and the lifting rod 646 also descend synchronously, causing the pressure plate 63 to fall quickly to press the filling material below.

[0049] At the same time, the pressure plate 63 will also move relative to the rotating shaft 44 during the descending process, thereby causing the two semicircular baffles 623 to disengage from the slots 625. During this process, the two semicircular baffles 623 are reset under the action of the torsion spring 624, blocking the annular groove below the pressure plate 63. Then, when the handle and the column block 6432 continue to rotate counterclockwise under the drive motor 6433, when they come into contact with the U-shaped rod 644, they can drive the U-shaped rod 644 to rotate counterclockwise to the top again, and then the above movement is repeated again, thereby realizing the layered pressing of the filling material.
