Technical Field

[0001] This utility model belongs to the field of foundation compaction technology, specifically relating to a foundation reinforcement and compaction device. Background Technology

[0002] Foundation compaction is a crucial step in building construction. By using various compaction equipment, strong pressure and impact are applied to the foundation soil to reduce soil porosity, increase soil density, bearing capacity and stability, effectively reduce the risk of building settlement, and lay a solid foundation for the safety of the building structure.

[0004] However, in the above scheme, the area of ​​the compaction plate used for compaction is fixed, so the area of ​​foundation reinforcement is fixed. When facing the same construction area, the fixed area compaction operation requires more time to carry out the compaction operation. It is impossible to flexibly adjust the area of ​​the compaction plate according to the foundation compaction situation, which limits the efficiency of the compaction operation. Utility Model Content

[0005] To address the limitations of existing fixed-area compaction methods, which require more time for compaction and cannot flexibly adjust the area of ​​the compaction plate according to the foundation compaction conditions, thus restricting the efficiency of the compaction operation, this invention provides a foundation reinforcement compaction device. This device allows for flexible adjustment of the folding and unfolding state of the second compaction plate at the first compaction plate, thereby adjusting the contact area for foundation compaction. It can be tailored to specific foundation conditions, adapting to complex working conditions, improving the equipment's versatility and flexibility, and reducing equipment purchase costs. The specific technical solution is as follows:

[0006] A foundation reinforcement and compaction device includes a compaction unit, and further includes: a vertical arm, a first compaction plate, a receiving groove, a clearance groove, a rotating shaft, a rotating seat, and a second compaction plate. The vertical arm is vertically arranged in the vertical direction; the first compaction plate is vertically and fixedly installed at the bottom end of the vertical arm; the clearance groove is formed on the side of the upper surface of the first compaction plate; the rotating shaft is rotatably connected to the inner cavity of the clearance groove; the rotating seat is fixedly installed on the rotating shaft; the second compaction plate is fixedly installed on the outer wall of the rotating seat; two receiving grooves are provided, and the two receiving grooves are symmetrically formed on the upper surface of the second compaction plate, and the clearance groove is connected to the receiving groove.

[0007] The positional relationship between the second tamping plate and the first tamping plate is divided into a first state and a second state. In the first state, the second tamping plate is rotated and fastened to the inner cavity of the receiving groove. In the second state, the second tamping plate rotates outward to the side wall of the first tamping plate.

[0008] In the above technical solution, a positioning assembly is provided between the first tamping plate and the second tamping plate. The positioning assembly includes: a first positioning hole, a second positioning hole, a positioning rod, a first fixing block, and a positioning bolt. The first positioning hole is opened in the front sidewall of the first tamping plate; the second positioning hole is opened in the front sidewall of the second tamping plate; the two ends of the positioning rod are respectively slidably inserted into the inner cavities of the first positioning hole and the second positioning hole, and the positioning rod is U-shaped; the first fixing block is fixedly installed on the front sidewall of the first tamping plate, and the first fixing block is located below the first positioning hole; the positioning bolt is threaded through the outer wall of the positioning rod from top to bottom and is threadedly connected to the first fixing block.

[0009] In the above technical solution, the compaction unit includes: a support frame, mounting columns, a stepper motor, a drive shaft, a drive wheel, a displacement plate, and an elastic element. The support frame is configured as an n-shape. Two mounting columns are provided, and the two mounting columns are respectively vertically installed on the top of the inner wall of the support frame. The stepper motor is installed on the outer wall of one of the mounting columns. The drive shaft is rotatably connected between the two mounting columns, and the drive shaft is connected to the output end of the stepper motor. The drive wheel is fixedly installed on the drive shaft, and the drive wheel is eccentrically arranged relative to the drive shaft. The displacement plate is fixedly and vertically installed on the top of the vertical arm. The elastic element is installed between the displacement plate and the support frame.

[0010] In the above technical solution, two sets of elastic elements are provided, and the two sets of elastic elements are arranged symmetrically with respect to the drive wheel.

[0011] In the above technical solution, a guide assembly is provided between the displacement plate and the support frame. The guide assembly includes: a second fixing block, a guide rod, and a slider. There are two second fixing blocks, and the two second fixing blocks are respectively fixedly installed on the inner side wall of the support frame. The guide rod is vertically installed between the two second fixing blocks. The slider is slidably sleeved on the guide rod, and the guide rod is fixedly connected to the side wall of the displacement plate.

[0012] In the above technical solution, the length of the guide rod is adapted to the displacement path length of the slider.

[0013] The above technical solution also includes: a top frame, connecting columns, and a handle. The top frame is fixed and vertically installed on the top of the support frame. There are two connecting columns, which are symmetrically installed on the side wall of the top frame. The handle is installed on the side of the connecting column away from the top frame.

[0014] In the above technical solution, casters are respectively provided on the left and right sides of the bottom end of the support frame.

[0015] The foundation reinforcement and compaction device of this utility model has the following advantages compared with the prior art:

[0016] I. Regarding the issue that fixed-area compaction methods require more time for compaction and cannot flexibly adjust the area of ​​the compaction plate according to the foundation compaction situation, thus limiting the efficiency of the compaction operation, this utility model can flexibly adjust the folded or unfolded state of the second compaction plate at the first compaction plate to flexibly adjust the contact area for foundation compaction. By increasing the area of ​​the compaction plate, more area can be compacted in a single pass when facing the same construction area, thus reducing the number of compaction passes, improving the efficiency of foundation compaction and reinforcement construction, enhancing the versatility and flexibility of the equipment, and reducing the cost of purchasing multiple equipment for different project needs;

[0017] Second, in this application, the compaction area can be reduced by retracting the second compaction plate onto the first compaction plate, and a small-area compaction plate can be assembled. This facilitates the compaction of narrow foundation areas and allows for targeted adjustment and treatment of the compaction plate area according to the actual compaction conditions of different foundations, flexibly adapting to the diverse needs of foundation compaction and reinforcement under various complex working conditions.

[0018] Third, this utility model, through the cooperation of components such as the first positioning hole, the second positioning hole, the positioning rod, the first fixing block, and the positioning bolt, can achieve the locking and positioning between the first tamping plate and the second tamping plate, thereby ensuring that the tamping plate can maintain a stable state after being adjusted to unfolded or folded, so as to ensure stability in the subsequent tamping process.

[0019] IV. By rationally configuring components such as drive wheels, displacement plates, and elastic elements, this utility model can precisely drive the first and second compaction plates to reciprocate in the vertical direction. When they move downward, they generate a strong force to achieve efficient compaction of the ground surface. When they move upward, they cleverly coordinate with the overall movement of the equipment to quickly transfer to areas that have not yet been compacted. Thus, during the continuous movement of the equipment, the compaction operation of the ground surface can be carried out continuously and without interruption, improving compaction efficiency and significantly enhancing the continuity and efficiency of engineering operations.

[0020] In summary, this utility model allows for flexible adjustment of the folding and unfolding state of the second compaction plate at the first compaction plate, thereby adjusting the contact area for foundation compaction. When the area is increased, the compaction area per pass is larger for the same construction scale, reducing the number of passes and improving construction efficiency. Retracting the second compaction plate to the first compaction plate reduces the compaction area, facilitating operation in narrow areas. It can be specifically adjusted according to the foundation conditions, adapting to complex working conditions, improving the equipment's versatility and flexibility, and reducing equipment purchase costs.

Detailed Implementation

[0028] The following are specific implementation cases and appendices. Figures 1 to 6 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0029] See Figures 1 to 6 As shown, a foundation reinforcement and compaction device includes a compaction unit, and further includes: a vertical arm 1, a first compaction plate 2, a receiving groove 3, a clearance groove 4, a rotating shaft 5, a rotating seat 6, and a second compaction plate 7. The vertical arm 1 is vertically arranged in the vertical direction; the first compaction plate 2 is vertically and fixedly installed at the bottom end of the vertical arm 1; two receiving grooves 3 are provided, and the two receiving grooves 3 are symmetrically opened on the upper surface of the second compaction plate 7; the clearance groove 4 is opened on the side of the upper surface of the first compaction plate 2, and the clearance groove 4 is connected to the receiving groove 3; the rotating shaft 5 is rotatably connected to the inner cavity of the clearance groove 4 through a bearing; the rotating seat 6 is fixedly installed on the second compaction plate 7. The first tamping plate 7 is fixedly installed on the rotating shaft 5; the second tamping plate 7 is fixedly installed on the outer wall of the rotating seat 6; the positional relationship between the second tamping plate 7 and the first tamping plate 2 is divided into a first state and a second state; in the first state, the second tamping plate 7 is rotated and locked into the inner cavity of the receiving groove 3, at which time the first tamping plate 2 is in contact with the ground while the second tamping plate 7 is not in contact with the ground, which is convenient for small-area foundation tamping operations; in the second state, the second tamping plate 7 is rotated outward to the side wall of the first tamping plate 2, at which time the lower surfaces of the second tamping plate 7 and the first tamping plate 2 are in contact with the ground, which can jointly achieve the tamping and reinforcement construction of the ground;

[0030] This solution allows for flexible adjustment of the state of the second compaction plate 7 relative to the first compaction plate 2, enabling folding or unfolding operations as needed. When dealing with large-area foundations, unfolding the second compaction plate 7 increases the compaction area, allowing for the coverage and compaction of a larger area in a single pass, significantly reducing the frequency of back-and-forth compaction and greatly improving the efficiency of foundation compaction and reinforcement. Conversely, when facing narrow or special foundation areas, folding the second compaction plate 7 into a smaller compaction plate flexibly addresses complex working conditions. This adjustable design greatly enhances the equipment's versatility and flexibility, eliminating the need for construction teams to purchase multiple specific pieces of equipment for different project needs, effectively reducing equipment procurement costs.

[0031] A positioning assembly is provided between the first compaction plate 2 and the second compaction plate 7. The positioning assembly includes: a first positioning hole 8, a second positioning hole 9, a positioning rod 10, a first fixing block 11, and a positioning bolt 12. The first positioning hole 8 is opened in the front side wall of the first compaction plate 2; the second positioning hole 9 is opened in the front side wall of the second compaction plate 7; the two ends of the positioning rod 10 are respectively slidably inserted into the inner cavities of the first positioning hole 8 and the second positioning hole 9, and the positioning rod 10 is U-shaped; the first fixing block 11 is fixedly installed in the front side wall of the first compaction plate 2, and the first fixing block 11 is located below the first positioning hole 8; the positioning bolt 12 is threaded through the outer wall of the positioning rod 10 from top to bottom and is threadedly connected to the first fixing block 11.

[0032] When fixing the second tamping plate 7 and the first tamping plate 2 after adjustment, unscrew the positioning bolt 12 to disengage from the first fixing block 11, pull out the positioning rod 10, and disengage the positioning bolt 12 from the first tamping plate 2 and the second tamping plate 7. Rotate the second tamping plate 7 to lock it into the storage slot 3. Then, insert the positioning rod 10 into the adjusted positions of the first positioning hole 8 and the second positioning hole 9. Finally, screw the positioning bolt 12 through the positioning rod 10 and insert it into the first fixing block 11 to lock the adjusted positioning rod 10. Through the coordinated operation of the first positioning hole 8, the second positioning hole 9, the positioning rod 10, the first fixing block 11, and the positioning bolt 12, the locking and positioning between the first tamping plate 2 and the second tamping plate 7 can be effectively achieved. After the tamping plate is adjusted to the unfolded or folded state, the locking and positioning mechanism formed by these components can ensure that the tamping plate always remains stable, thus providing a solid guarantee for the smooth and stable tamping work to be carried out subsequently.

[0033] Main references Figure 1 and Figure 2 As shown, the compaction unit includes: a support frame 13, mounting columns 14, a stepper motor 15, a drive shaft 16, a drive wheel 17, a displacement plate 18, and an elastic element 19. The support frame 13 is configured as an n-shape; there are two mounting columns 14, which are respectively vertically mounted on the top of the inner wall of the support frame 13; the stepper motor 15 is mounted on the outer wall of one of the mounting columns 14; the drive shaft 16 is rotatably connected between the two mounting columns 14, and the drive shaft 16 is connected to the output end of the stepper motor 15; the drive wheel 17 is fixedly mounted on the drive shaft 16, and the drive wheel 17 is eccentrically positioned relative to the drive shaft 16; the displacement plate 18 is fixedly and vertically mounted on the top of the vertical arm 1; the elastic element 19 is installed between the displacement plate 18 and the support frame 13.

[0034] The stepper motor 15 is turned on, driving the drive shaft 16 and the eccentrically positioned drive wheel 17 to rotate circumferentially around the axis. During rotation, the position change of the drive wheel 17 and drive shaft 16 causes the elastic element 19 to work, driving the displacement plate 18 to rise and reset. At the same time, the drive wheel 17 drives the displacement plate 18 to reciprocate in the vertical direction with a height difference. This movement is transmitted to the connected vertical arm 1, the first tamping plate 2, and the second tamping plate 7, making them reciprocate vertically in sync. When the first tamping plate 2 and the second tamping plate 7 touch the ground, they tamp the ground. After tamping, the elastic potential energy of the elastic element 19 pushes them to reset and detach from the ground. The equipment moves to the next station, and the operation is repeated to achieve continuous tamping.

[0035] Specifically, there are two sets of elastic elements 19, and the two sets of elastic elements 19 are symmetrically arranged with respect to the drive wheel 17 to ensure that the two sets of elastic elements 19 can cause the displacement plate 18 to move smoothly in the vertical direction, and avoid the displacement plate 18 from being tilted due to uneven force during the displacement process caused by the setting of a single elastic element 19.

[0036] In addition, a guide assembly is provided between the displacement plate 18 and the support frame 13. The guide assembly includes: a second fixing block 20, a guide rod 21, and a slider 22. There are two second fixing blocks 20, and the two second fixing blocks 20 are respectively fixedly installed on the inner side wall of the support frame 13. The guide rod 21 is vertically installed between the two second fixing blocks 20. The slider 22 is slidably sleeved on the guide rod 21, and the guide rod 21 is fixedly connected to the side wall of the displacement plate 18. The length of the guide rod 21 is adapted to the displacement path length of the slider 22 to ensure that the length of the guide rod 21 is sufficient for the slider 22 to move up and down.

[0037] When the displacement plate 18 moves vertically, it can drive the slider 22 to move along the outer wall of the guide rod 21 to ensure that the displacement plate 18 is always limited and guided in the vertical direction during the displacement process.

[0038] This solution also includes: a top frame 23, connecting columns 24, and a handle 25. The top frame 23 is fixed and vertically installed on the top of the support frame 13. There are two connecting columns 24, which are symmetrically installed on the side walls of the top frame 23. The handle 25 is installed on the side of the connecting column 24 away from the top frame 23. The entire equipment can be controlled by manually holding the handle 25, which facilitates subsequent displacement and also makes it easy to control the equipment to perform compaction processing in a certain area. The bottom left and right sides of the support frame 13 are equipped with casters 26. The casters 26 are commonly used casters with a self-locking structure. They can be locked or unlocked as needed. When locked, the casters 26 can ensure the stable placement of the equipment. When unlocked, the casters 26 can enable the overall movement of the equipment. This is sufficient to meet the usage requirements. The model of the above-mentioned existing components is not limited or described in detail.

[0039] It is worth noting that in this application, the stepper motor 15 is a commonly used self-locking motor with a lockable output end. When it stops, the output end can lock itself and will not rotate under external force. It is sufficient to meet the above-mentioned usage requirements. There is no need to limit the model of the above-mentioned existing components or describe them in detail. The elastic element 19 is a commonly used elastic element that can expand and contract under the action of external force. It is composed of a spring and a telescopic rod. The spring is sleeved on the telescopic rod. The telescopic rod is a commonly used telescopic rod that consists of two interlocking rods. It can cause the total length of the telescopic rod to change under the action of external force. It is sufficient to meet the usage requirements. There is no need to limit the model of the above-mentioned existing components or describe them in detail.

[0040] The working principle of the foundation reinforcement and compaction device in this embodiment is as follows:

[0041] When a large-area compaction plate is required for foundation compaction and reinforcement, the stepper motor 15 is activated, causing the drive shaft 16 and drive wheel 17 to rotate circumferentially around the axis. Since the drive wheel 17 is eccentrically positioned relative to the drive shaft 16, the change in relative position between the drive wheel 17 and the drive shaft 16 during rotation causes the elastic element 19 to work. The force generated by the elastic element 19 drives the displacement plate 18 to rise and reset. Simultaneously, due to its eccentric characteristic, the rotating drive wheel 17 drives the displacement plate 18 to reciprocate in the vertical direction with a certain height difference. This reciprocating movement in the vertical direction is transmitted to the vertical axis connected to the displacement plate 18. The straight arm 1, the first tamping plate 2, and the second tamping plate 7 move synchronously in the vertical direction. When the first tamping plate 2 and the second tamping plate 7 move downwards to contact the ground, they generate a strong impact force, thus achieving the tamping and reinforcement operation of the ground. After completing one tamping operation, the elastic potential energy stored in the elastic element 19 is used to release the elastic force, pushing the displacement plate 18 and the connected vertical arm 1, the first tamping plate 2, and the second tamping plate 7 upwards to reset them and lift them off the ground. At this time, the equipment can move smoothly to the next tamping position and repeat the above process to achieve continuous and uninterrupted tamping operation.

[0042] When a small-area compaction plate is required for foundation compaction and reinforcement, the positioning bolt 12 is rotated until it is disengaged from the inner cavity of the first fixing block 11. The positioning rod 10 and the positioning bolt 12 are pulled outward to disengage from the first compaction plate 2 and the second compaction plate 7. The second compaction plate 7 is rotated to flip and snap into the receiving groove 3. The positioning rod 10 is then reinserted into the inner cavity of the first positioning hole 8 and the second positioning hole 9 after the position has been adjusted. The positioning bolt 12 is then spirally inserted through the positioning rod 10 and inserted into the inner cavity of the first fixing block 11 to lock the positioning rod 10 after the position has been adjusted. This locks the position between the second compaction plate 7 and the first compaction plate 2 after the position has been adjusted, ensuring the stability between the first compaction plate 2 and the second compaction plate 7 during subsequent operations.

[0043] This utility model allows for flexible adjustment of the folding and unfolding state of the second compaction plate 7 at the first compaction plate 2, thereby adjusting the contact area for foundation compaction. When the area is increased, the compaction area per pass is larger for the same construction scale, reducing the number of passes and improving construction efficiency. Retracting the second compaction plate 7 to the first compaction plate 2 can reduce the compaction area, facilitating operation in narrow areas. It can be adjusted according to the foundation conditions to adapt to complex working conditions, improving the versatility and flexibility of the equipment and reducing equipment purchase costs.
