Description

Technical Field

[0001] The invention relates to the technical field of foundation treatment, and in particular to deep compaction treatment equipment for widening a foundation in a collapsible area. Background Art

[0002] Wet-sinking areas refer to areas where the soil has become soft and unstable due to excessive water content. In order to solve the problem of wet-sinking areas, the following measures can be taken: Widening the foundation: By expanding the area of ​​the foundation to increase the support area, reduce the bearing pressure of the foundation, and thus improve the stability of the foundation. Deep compaction treatment: By using professional compaction equipment to perform deep compaction treatment on the foundation, the density and bearing capacity of the soil are increased, and the stability and bearing capacity of the foundation are improved.

[0003] The compaction method is usually used to compact the soil layer. However, rolling can only handle soil within 50 cm, while the dynamic compaction method can handle fill above 10 meters. If the soil filling can reach 30 cm, the standard vibration rolling can also meet the elevation requirements. However, most foundations cannot be filled and compacted layer by layer. The dynamic compaction method can effectively solve many problems left in the filling link, especially the compaction treatment of subsidence areas.

[0004] For example, the Chinese patent with publication number CN116537152A discloses an elastic dynamic compaction method and construction equipment, which relates to the field of foundation treatment technology, especially an elastic dynamic compaction method and construction equipment, in which an elastic device is arranged between the lifting device and the rammer; during the lifting process of the rammer, the elastic device gradually stretches and accumulates force under the action of the rammer; when the lifting device releases the rammer, the elastic device applies elastic potential energy to the rammer. While ensuring the tamping effect, the drop distance of the dynamic compaction can be reduced, and the accuracy of the tamping point can also be ensured; the adjustability of parameters in the dynamic compaction process is improved, breaking through the limitations of conventional construction conditions, effectively expanding the application scenarios and scope of dynamic compaction construction, and effectively reducing construction costs; the structure is simple and reasonable, easy to use, and suitable for promotion.

[0005] However, the above elastic compaction method and construction equipment still have some shortcomings in actual use:

[0006] 1. The above-mentioned elastic tamping method and construction equipment use an elastic device to apply elastic potential energy to the tamping hammer. While ensuring the tamping effect, the drop distance of the tamping can be reduced and the accuracy of the tamping point can be ensured. However, when the tamping hammer is recovered, the elastic device cannot provide energy for the recovery of the tamping hammer, which can easily cause wear and damage to the device.

[0007] 2. The above-mentioned elastic compaction method and construction equipment utilize an elastic device to drive a rammer through a lifting device to compact the ground. However, since it only utilizes a lifting device to drive a rammer to move for compaction work, when adjusting the compaction position, the rammer can only be moved through the lifting device, resulting in a slow travel speed and poor compaction effect.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing elastic compaction method and construction equipment. Summary of the invention

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 10 While embodiments of the invention have been described in detail, the invention can be implemented in many different ways as defined and covered by the claims.

[0035] The embodiment of the present application discloses a deep compaction processing equipment for widening the foundation in a collapsible area. It is explained that the deep compaction processing equipment for widening the foundation in a collapsible area is mainly used in the process of foundation treatment. In terms of technical effect, it can avoid the problem of wear and damage of the device caused by pulling the compaction blocks for recovery when recovering the compaction blocks, reducing the service life of the equipment, and increasing the maintenance and replacement costs; further, the deep compaction processing equipment for widening the foundation in a collapsible area can also solve the problem of slow transfer speed when compacting foundations in different positions, resulting in unsatisfactory compaction effect.

[0036] Embodiment 1:

[0037] Reference Figure 1 , Figure 2 and Figure 3 As shown, it includes a support frame 1, and the support frame 1 includes a sliding frame 10 and a moving frame 11. A tamping unit 2 is slidably installed on the sliding frame 10, and the tamping unit 2 includes a driving box 20. A driving shaft 21 with one end passing through the driving box 20 is rotatably installed inside the driving box 20 along its length direction through a supporting block, and a pull rope 22 is wound around the driving shaft 21. The pull rope 22 passes through the driving box 20 and is installed with a fixed block 23, and a tamping block 24 is installed on the fixed block 23; the sliding frame 10 is assembled according to the size of the wet-collapsed area to be compacted on site, and the tamping unit 2 on the sliding frame 10 slides on the sliding frame 10 to compact the wet-collapsed area below, and the sliding frame 10 is driven to move by the moving frame 11, thereby realizing all-round tamping of the wet-collapsed area.

[0038] The driving box 20 is internally provided with a driving mechanism 3 for driving the driving shaft 21 to rotate so as to recycle the compacting block 24 by using the pull rope 22. The compacting block 24 on the pull rope 22 is used to compact the ground in the collapsible area by free fall. After the compacting block 24 is recovered by rotating the driving shaft 21 in coordination with the pull rope 22, the next position is compacted or the current position is compacted again.

[0039] Reference Figure 3 , Figure 5 and Figure 6 As shown, it is a structural schematic diagram of recycling the compacting block 24; specifically, the driving mechanism 3 includes a rotating shaft 30, and the rotating shaft 30 is rotatable along the length direction of the driving box 20 and is arranged in the driving box 20. A motor 31 is also installed inside the driving box 20, and the output end of the motor 31 is connected to the rotating shaft 30. A transmission shaft 32 coaxially arranged with the driving shaft 21 is rotatably installed on one side of the length direction of the driving shaft 21 in the driving box 20, and synchronous wheels 33 are provided on the transmission shaft 32 and the rotating shaft 30, and a synchronous belt 34 is commonly sleeved on the synchronous wheel 33, and a connecting member 35 is commonly provided on the transmission shaft 32 and the driving shaft 21.

[0040] When the compacting block 24 falls onto the ground in the collapsible area, the motor 31 is started to drive the rotating shaft 30 to rotate, and then the transmission shaft 32 is driven to rotate under the cooperation of the synchronous wheel 33 and the synchronous belt 34, and then the driving shaft 21 is driven to rotate by the connecting member 35.

[0041] The purpose of setting the connecting member 35 is that the connecting member 35 can control whether the transmission shaft 32 and the driving shaft 21 rotate synchronously. Since the compacting block 24 needs to be in free fall to compact the ground of the collapsible area by gravity, and since the pull rope 22 connected to the compacting block 24 is wound on the driving shaft 21, when the compacting block 24 falls, since the motor 31 is not working, the driving shaft 21 will not rotate, which will affect the descent of the compacting block 24. There is a conflict between the two and the effect of compacting the ground in the collapsible area cannot be achieved. Therefore, when the compacting block 24 descends, it is necessary to cut off the connection between the driving shaft 21 and the motor 31, and when the compacting block 24 is recovered, it is necessary to increase the connection between the driving shaft 21 and the motor 31 so that the two can work synchronously.

[0042] Reference Figure 3 , Figure 5 and Figure 6As shown, it is a schematic diagram of the structure for controlling whether the transmission shaft 32 and the driving shaft 21 rotate synchronously; specifically, the connecting member 35 includes a threaded rod 350, a threaded groove 351 is provided at one end of the transmission shaft 32 close to the driving shaft 21, the threaded rod 350 is threadedly arranged in the threaded groove 351, a square connecting block 352 is installed at one end of the threaded rod 350 close to the driving shaft 21, a cylinder 353 is installed on the bottom wall of the driving box 20, a top block 354 is installed on the telescopic end of the cylinder 353, and the end of the top block 354 away from the cylinder 353 is movably matched with the connecting block 352, and a connecting groove matching the connecting block 352 is provided at one end of the driving shaft 21 close to the threaded rod 350.

[0043] When the rotating shaft 30 drives the transmission shaft 32 to rotate, the threaded groove 351 on the transmission shaft 32 cooperates with the threaded rod 350 to drive the connecting block 352 on the threaded rod 350 to approach the driving shaft 21. During this process, the telescopic end of the cylinder 353 extends, presses against the connecting block 352 to prevent it from rotating, and then enters the connecting groove. When the connecting block 352 completely enters the connecting groove, the connecting block 352 has no forward space. At this time, the telescopic end of the cylinder 353 contracts, canceling the limit on the connecting block 352, and then the transmission shaft 32 will drive the connecting block 352 to rotate synchronously, which can drive the driving shaft 21 to rotate synchronously.

[0044] Reference Figure 5 and Fig. 9 As shown, it is a schematic diagram of a structure that utilizes kinetic energy recovery to make the recovery of the tamping block 24 more labor-saving; specifically, a kinetic energy recovery mechanism 4 is also arranged inside the drive box 20, and the kinetic energy recovery mechanism 4 includes a drive disk 40, and the drive disk 40 is arranged outside the drive box 20 and concentrically arranged with the drive shaft 21, and a volute spring 41 is arranged inside the drive disk 40, and the end of the drive shaft 21 located outside the drive box 20 is connected to the center of the volute spring 41.

[0045] When the tamping block 24 descends, it will indirectly drive the drive shaft 21 to rotate. Subsequently, the volute spring 41 in the drive disk 40 will be driven by the drive shaft 21 to gradually shrink from the outside to the center to accumulate force until the tamping block 24 falls to the ground, and the volute spring 41 will stop shrinking. When the drive shaft 21 indirectly drives the tamping block 24 to rise, at this time, since the rotation direction of the drive shaft 21 tends to the release direction of the contraction force of the volute spring 41, the volute spring 41 will open in this process and exert a reverse force on the drive shaft 21, increasing the rotation force of the drive shaft 21, so that the drive shaft 21 can have a greater force to pull up the tamping block 24, indirectly eliminating the output speed of the motor 31, so that the drive shaft 21 can more easily pull up the tamping block 24, and save the driving energy of the motor 31, thereby increasing the applicability of the present invention.

[0046] Reference Figure 5 and Fig. 9As shown, it is a schematic diagram of the structure for controlling the release force of the volute spring 41; specifically, a support plate is installed at one end of the drive shaft 21 outside the drive disk 40, and a reciprocating screw 50 is rotatably arranged on the support plate and is perpendicular to the axial direction of the drive shaft 21. The support plate is also provided with a limiting rod 51 parallel to the reciprocating screw 50, and a counterweight block 52 is commonly arranged on the reciprocating screw 50 and the limiting rod 51, and the counterweight block 52 is threadedly connected to the reciprocating screw 50, and the counterweight block 52 is slidably connected to the limiting rod 51.

[0047] The driving shaft 21 can drive the support plate to rotate synchronously, and the support plate can drive the counterweight block 52 to rotate along its axis through the reciprocating screw 50 and the limit rod 51. When the reciprocating screw 50 rotates, it can drive the counterweight block 52 to reciprocate under the limit guide of the limit rod 51, thereby changing the distance between the counterweight block 52 and the support plate.

[0048] In the actual working process, the impact force of the tamping block 24 is not certain. Therefore, before tamping, the tamping force is predetermined, and the external driving device is connected to one end of the reciprocating screw 50 to drive the reciprocating screw 50 to rotate and adjust the distance between the counterweight 52 and the support plate. Since the distance between the counterweight 52 and the axis of the drive shaft 21 changes, the force of the counterweight 52 indirectly driven by the drive shaft 21 to rotate along its axis will also change, indirectly affecting the speed at which the drive shaft 21 releases the tamping block 24 to fall; when the counterweight 52 is close to the support plate, the rotation force required by the drive shaft 21 is small, so the tamping block 24 descends faster. When the distance between the counterweight 52 and the support plate is far, the driving force required by the drive shaft 21 will become larger, which indirectly causes the tamping block 24 to fall slower.

[0049] Reference Figure 4 , Figure 7 and Figure 8 As shown, it is a schematic diagram of the structure for fixing the tamping block 24; specifically, a fixing mechanism 6 for fixing the tamping block 24 is installed on the outer side of the fixing block 23, and the fixing mechanism 6 includes a fixing ring 60 fixed to the bottom of the driving box 20, and the fixing block 23 and the fixing ring 60 are slidably penetrated, and the fixing ring 60 is provided with a fixing groove along its width direction, and a fixing shaft 61 penetrating the fixing ring 60 is slidably installed in the fixing groove, and a matching groove matching with the fixing shaft 61 is provided on the fixing block 23, and a counter plate 62 connected to the fixing shaft 61 is slidably installed at one end of the fixing groove away from the fixing block 23, and a spring 63 connected to one end of the fixing groove close to the fixed block 23 is installed on the side of the counter plate 62 close to the fixed block 23.

[0050] When the tamping block 24 needs to be recovered, the driving shaft 21 is rotated to drive the pull rope 22 to drive the tamping block 24 on the fixed block 23 to move upward. After moving to the top, the fixed shaft 61 is clamped in the matching groove on the fixed block 23 under the action of the spring 63. Before moving the tamping block 24 to another position or tamping the current position again, under the action of the fixing ring 60, the driving shaft 21 is always clamped in the matching groove to fix the fixed block 23, thereby preventing the tamping block 24 from falling. When the ground needs to be tamped, it is necessary to drive the spring 63 to contract to slide the fixed shaft 61 out of the matching groove. After the fixed block 23 loses the limit of the fixed shaft 61, it will drive the tamping block 24 to fall and complete the work of tamping the ground.

[0051] It should be noted that the time when the fixed shaft 61 slides out of the matching groove is later than the time when the connecting block 352 slides out of the connecting groove. This is conducive to disconnecting the connection between the drive shaft 21 and the motor 31 before the fixed block 23 drives the tamping block 24 to fall. The fixed shaft 61 can fix the fixed block 23 before the fixed block 23 performs free fall. When the fixed block 23 needs to perform free fall, its indirect connection with the motor 31 can also be disconnected before that, so as to prevent the fixed block 23 from falling and causing the drive shaft 21 to reverse and cause damage to the output shaft of the non-working motor 31.

[0052] Reference Figure 4 , Figure 7 and Figure 8 As shown, it is a structural schematic diagram of causing the driving shaft 21 to slide out of the matching groove; specifically, an enabling unit 7 for driving the fixed shaft 61 to slide is also installed on the driving box 20, and the enabling unit 7 includes an enabling gear ring 71 rotatably installed at the bottom of the driving box 20 and sleeved on the outside of the fixed ring 60, and an enabling block 72 is arranged on the outside of the fixed ring 60 at one end of the fixed shaft 61 away from the fixed block 23, and an enabling groove 73 matching with the enabling block 72 is opened on the side of the enabling gear ring 71 away from the driving box 20, and the enabling groove 73 is inclined from the inside to the outside on the enabling gear ring 71.

[0053] When the fixed block 23 moves upward, the rotating toothed ring 71 drives the enabling groove 73 on it to match with the enabling block 72 on the fixed shaft 61, and the enabling block 72 slides in the enabling groove 73, driving the fixed shaft 61 to slide out of the matching groove.

[0054] Reference Figure 6As shown, it is a structural schematic diagram that drives the fixed block 23 and the fixed shaft 61 to work synchronously; specifically, the drive box 20 is also provided with a linkage member 8 that drives the movable gear ring 71 to rotate, and the linkage member 8 includes a linkage shaft 80, and the linkage shaft 80 is rotatably arranged on the drive box 20 and one end of the linkage shaft 80 passes through the drive box 20, and the end of the linkage shaft 80 located outside the drive box 20 is installed with a linkage gear 81 that meshes with the movable gear ring 71, and the end of the linkage shaft 80 located inside the drive box 20 and the transmission shaft 32 are both installed with a bevel gear 82, and the two bevel gears 82 are meshed with each other.

[0055] When the transmission shaft 32 rotates, the linkage shaft 80 is driven to rotate through the bevel gear 82, and then the linkage gear 81 on the linkage shaft 80 rotates synchronously, driving the driving gear ring 71 meshing with it to rotate, and then the rotation of the transmission shaft 32 drives the fixed block 23 to move and the rotation of the driving gear ring 71 drives the fixed shaft 61 to slide, which can be carried out synchronously.

[0056] Embodiment 2:

[0057] On the basis of the first embodiment, in order to further prevent the counterweight block 52 from being displaced and affecting the working efficiency when the reciprocating screw 50 rotates, a limiting mechanism 9 is also proposed, which is conducive to limiting the counterweight block 52 during the rotation process.

[0058] Reference Fig. 9 and Fig.10 As shown, it is a schematic diagram of the structure for preventing the counterweight block 52 from being displaced during rotation; specifically, the limiting mechanism 9 includes a connecting plate 90, and the reciprocating screw 50 and the limiting rod 51 are jointly provided with a connecting plate 90 at one end away from the driving shaft 21, the reciprocating screw 50 is rotatably connected with the connecting plate 90, and the end of the connecting plate 90 away from the reciprocating screw 50 is provided with a limiting groove 91 on the outer side of the reciprocating screw 50, and the reciprocating screw 50 is installed with a ratchet 92 at one end of the limiting groove 91, and a ratchet groove 93 is provided on the ratchet 92, and a ratchet tooth 94 matching the ratchet groove 93 is provided in the limiting groove 91 through a torsion spring.

[0059] The purpose of setting the ratchet wheel 92 and the ratchet teeth 94 is that in the process of the counterweight 52 following the rotation of the reciprocating screw 50, under the action of centrifugal force, the counterweight 52 may be caused to move away from the drive shaft 21, and in this process, the reciprocating screw 50 is driven to rotate. By utilizing the cooperation between the ratchet groove 93 and the ratchet teeth 94, the reciprocating screw 50 cannot rotate in the opposite direction, so that the counterweight 52 can be further limited together with the limit shaft to prevent it from being displaced during the rotation process and affecting the work efficiency.

[0060] During operation: First, a sliding frame 10 of a suitable length is assembled according to the width of the foundation to be compacted, and then the compacting unit 2 on the sliding frame 10 is driven to move to a designated position by the moving frame 11.

[0061] Step 2: Start the motor 31 to drive the rotating shaft 30 to rotate, and then use the cooperation between the transmission shaft 32 and the connecting member 35 to drive the driving shaft 21 to rotate, reel in the pull rope 22 on the driving shaft 21, and move the tamping block 24 to the highest point.

[0062] Step 3: After loosening the limit of the connecting block 352 on the driving shaft 21, the driving shaft 21 is driven to make the counterweight block 52 on the fixed block 23 fall freely to compact the ground in the collapsible area.

[0063] Step 4: After the compaction work is completed, the connecting block 352 is driven into the connecting groove on the driving shaft 21, and the motor 31 is started to rotate the driving shaft 21 to recycle the compaction block 24.
