Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of soil and rock compaction technology, and more specifically, to a soil and rock compaction device for soil and rock engineering. Background Technology

[0002] Compaction is a construction operation that uses heavy objects to repeatedly fall freely and tamp down the foundation or fill soil and stone materials to increase their density.

[0003] In the existing technology, the power source for ramming equipment is mostly hydraulically driven. It requires repeated ramming of the soil and rock to compact the ground. However, the power supply consumes a lot of resources and cannot achieve continuous ramming.

[0004] A search revealed that Chinese patent CN221255432U discloses a soil and rock compaction device for construction in complex terrain. The device automatically and continuously compacts soil and rock by driving the soil compaction plate to move up and down in a cyclical manner. It is also convenient to use the lifting plate to elastically avoid the soil and rock protrusions that prevent the soil compaction plate from falling into place. However, during the automatic and continuous compaction of soil and rock, the soil compaction plate collides with the soil and rock, and the two will generate mutual impact force, which may cause the entire device to shake and lack stability. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a soil and rock compaction device for geotechnical engineering, which solves the technical problem in the prior art that during the automatic continuous compaction of soil and rock, the ramming plate collides with the soil and rock, and the two generate mutual impact force, which may cause the entire device to shake and lack stability.

[0006] According to one aspect, at least one embodiment of this disclosure provides a soil and rock compaction device for geotechnical engineering, including a base with a plurality of drive wheels mounted on the base and an installation groove formed on the base, and further including a fixing frame, a compaction mechanism and a reinforcement component, wherein the bottom end of the fixing frame is fixedly connected to the inner wall of the installation groove, the compaction mechanism is disposed within the fixing frame for continuously compacting the soil and rock, and the reinforcement component is disposed on the outer wall of the fixing frame for reinforcing the stability of the base and the soil and rock.

[0007] To enable continuous compaction of soil and rock, the compaction mechanism includes two connecting plates, a compaction frame, a rotating shaft, a compaction block, a first motor, multiple second springs, a telescopic rod, and a compaction seat. The two connecting plates are elastically slidably engaged with the inner walls of the fixed frame via two first springs. Both ends of the compaction frame are fixedly connected to the two connecting plates. Both ends of the rotating shaft are rotatably connected to the two inner walls of the compaction frame. One end of the compaction block is coaxially fixedly connected to the rotating shaft, which passes through one end of the compaction block. The first motor is mounted on the connecting plates and symmetrically arranged on both sides of the compaction frame, coaxially connected to the rotating shaft. One end of each second spring is fixedly connected to the bottom of the compaction frame and is fitted onto the outside of the telescopic rod. One end of the telescopic rod is fixedly connected to the bottom of the compaction frame. The other ends of both the second spring and the telescopic rod are fixedly connected to one end of the compaction seat.

[0008] To prevent the device from tilting during the compaction of soil and rock and to increase the stability of the base, the reinforcement assembly includes multiple fixing plates, screws, a rotating seat, a connecting rod, and a piercing head. The multiple fixing plates are circumferentially arranged on the outer side wall of the fixing frame. The screws are threadedly connected to the fixing plates. One end of the rotating seat is fixedly connected to the top end of the screw. One end of the connecting rod is fixedly connected to the bottom end of the screw. One end of the piercing head is fixedly connected to the bottom end of the connecting rod.

[0009] In order to guide the compaction seat and make it vertically compact the soil and rock, the fixing frame can also scrape off the soil and rock adsorbed on the outer periphery of the compaction seat, and the outer side wall of the compaction seat is in contact with the inner side wall of the fixing frame.

[0010] To facilitate the movement of the device, a push plate is fixedly connected to one end of the base, and a push rod is provided at one end of the push plate.

[0011] To prevent the piercing head from rubbing against the soil and rock during device movement and thus increasing resistance, the bottom of the piercing head is higher than the bottom of the drive wheel.

[0012] In order to make the compaction block drive the compaction frame to move up and down repeatedly when it rotates around the axis of the rotating shaft, the cross-sectional area of ​​one end of the compaction block is smaller than the cross-sectional area of ​​the other end.

[0013] In order to continuously drive the connecting plate to move up and down, two first springs are symmetrically arranged on the upper and lower sides of the connecting plate.

[0014] In order for the connecting plate to move up and down within the inner wall of the fixed frame and to limit the movement of the connecting plate, a moving groove that cooperates with the connecting plate is provided on the inner wall of the fixed frame.

[0015] In order to provide a suitable moving distance for the compaction seat to compact the soil and rock, the length of the moving groove is greater than the distance between the bottom end of the compaction seat and the bottom end of the drive wheel.

[0016] The beneficial effects of the embodiments disclosed herein are as follows:

[0017] 1. In this disclosure, by setting up a reinforcement component, after the device is moved to the use position, the rotating base is manually rotated to make the screw drive the connecting rod and the piercing head to move downward, so that the piercing head and the connecting rod are driven into the rock and soil, increasing the contact area between the base and the rock and soil surface and improving the stability of the device.

[0018] 2. In this disclosure, a compaction mechanism is provided. The first motor drives the compaction block to make circular motion around the axis of the rotating shaft. When the compaction block rotates, it generates a large outward force and drives the compaction frame to move vertically up and down. The two first springs at the bottom of the connecting plate continuously contract and stretch. The compaction frame drives the second spring and the compaction seat to move up and down. The compaction seat repeatedly and continuously compacts the soil and rock. This can fully and continuously compact the soil and rock and improve work efficiency. Attached Figure Description

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-5 As shown, it illustrates a geotechnical engineering soil compaction device according to an embodiment of the present disclosure, including a base 1, on which a plurality of drive wheels 2 are mounted. To facilitate the movement of the device, a push plate 18 is fixedly connected to one end of the base 1, and a push rod 19 is provided at one end of the push plate 18. By pushing the push rod 19, a pushing force is given to the push plate 18 and the base 1, causing the plurality of drive wheels 2 to rotate, thereby driving the entire device to move. The movable base 1 is provided with an installation groove 3, and also includes a fixing frame 4, a compaction mechanism and a reinforcement component.

[0033] like Figure 2 , Figure 3 and Figure 4As shown, the bottom end of the fixed frame 4 is fixedly connected to the inner wall of the mounting groove 3. The compaction mechanism is set inside the fixed frame 4 for continuous compaction of the soil and rock. To enable continuous compaction of the soil and rock, the compaction mechanism includes two connecting plates 5, a compaction frame 7, a rotating shaft 8, a compaction block 9, a first motor 10, multiple second springs 11, a telescopic rod, and a compaction seat 12. The two connecting plates 5 are elastically slidably engaged with the inner wall of the fixed frame 4 through two first springs 6. To continuously drive the connecting plates 5 to move up and down, the two first springs 6 are symmetrically arranged on the upper and lower sides of the connecting plates 5. To allow the connecting plates 5 to move up and down within the inner wall of the fixed frame 4 and to limit the movement of the connecting plates 5, the compaction seat 12 is also provided. 2. Provide a suitable moving distance to compact the soil and rock. The length of the moving groove 20 is greater than the distance between the bottom end of the compaction seat 12 and the bottom end of the drive wheel 2. The inner side wall of the fixed frame 4 is provided with a moving groove 20 that cooperates with the connecting plate 5. The two ends of the compaction frame 7 are fixedly connected to the two connecting plates 5 respectively. The two ends of the rotating shaft 8 are rotatably connected to the two inner side walls of the compaction frame 7 respectively. One end of the compaction block 9 is coaxially fixedly connected to the rotating shaft 8. In order to make the compaction block 9 drive the compaction frame 7 to move up and down repeatedly when rotating around the axis of the rotating shaft 8, the cross-sectional area of ​​one end of the compaction block 9 is smaller than the cross-sectional area of ​​the other end. The rotating shaft 8 passes through one end of the compaction block 9. The first motor 10 is installed on the connecting plate 5. The first motor 10 is symmetrically arranged in the compaction frame 7. The two sides of the frame 7 are coaxially connected to the rotating shaft 8. One end of the second spring 11 is fixedly connected to the bottom end of the compaction frame 7. The second spring 11 is fitted on the outside of the telescopic rod, one end of which is fixedly connected to the bottom end of the compaction frame 7. The other ends of the second spring 11 and the telescopic rod are both fixedly connected to one end of the compaction seat 12. In order to guide the compaction seat 12 and make it longitudinally perpendicular to the soil and rock for compaction, the fixed frame 4 can also scrape off the soil and rock adsorbed on the outer periphery of the compaction seat 12. The outer side wall of the compaction seat 12 is in contact with the inner side wall of the fixed frame 4. By starting the first motor 10, the output ends of the two first motors 10 rotate, driving the rotating shaft 8 to rotate. The rotating shaft 8 drives the compaction block 9 to rotate. The compaction block 9 is centered on the axis of the rotating shaft 8. When the compaction block 9 rotates in a circular motion, the cross-sectional area of ​​the end of the compaction block 9 furthest from the axis of rotation 8 is larger. When the compaction block 9 rotates, it generates a large outward force and drives the compaction frame 7 to move. Due to the sliding fit between the connecting plate 5 and the inner wall of the moving groove 20, the compaction frame 7 is laterally limited. Driven by the compaction block 9, the compaction frame 7 moves vertically up and down. The two first springs 6 at the bottom and bottom ends of the connecting plate 5 continuously contract and stretch. The compaction frame 7 drives the second spring 11 and the compaction seat 12 to move up and down. The compaction seat 12 repeatedly compacts the soil and rock. By setting the second spring 11, it can be applied to uneven soil and rock surfaces. The adjustment and contraction of the second spring 11 drives the compaction seat 12 to compact the soil and rock.

[0034] like Figure 1 and Figure 5As shown, the reinforcement component is installed on the outer wall of the fixed frame 4 to reinforce the stability of the base 1 and the soil. To prevent the device from tilting during the compaction of the soil, the stability of the base 1 can be increased. The reinforcement component includes multiple fixing plates 13, screws 14, rotating seats 15, connecting rods 16, and piercing heads 17. The multiple fixing plates 13 are circumferentially arranged on the outer wall of the fixed frame 4. The screws 14 are threadedly connected to the fixing plates 13. One end of the rotating seat 15 is fixedly connected to the top end of the screws 14. One end of the connecting rod 16 is fixedly connected to the bottom end of the screws 14. One end of the piercing head 17 is connected to the bottom end of the connecting rod 16. To prevent the piercing head 17 from rubbing against the soil and rock during device movement and thus increasing resistance, the bottom of the piercing head 17 is higher than the bottom of the drive wheel 2. When the device is moved to the corresponding position, the rotating seat 15 is rotated, and the rotating seat 15 moves downward. The rotating seat 15 drives the screw 14 to move downward, and the screw 14 drives the connecting rod 16 and the piercing head 17 to move downward. By providing the connecting rod 16, the depth of penetration into the ground is increased, and the screw 14 is prevented from entering the soil and rock. This allows the piercing head 17 and the connecting rod 16 to penetrate the soil and rock, increasing the contact area between the base 1 and the soil and rock surface and improving the stability of the device.

[0035] Working principle: The geotechnical engineering compaction device is pushed to the location where the geotechnical engineering needs to be compacted. Pushing the push rod 19 provides thrust to the push plate 18 and base 1, causing multiple drive wheels 2 to rotate, thus moving the entire device. When the device reaches the corresponding position, rotating the rotating seat 15 causes it to move downwards. The rotating seat 15 drives the screw 14 downwards, which in turn drives the connecting rod 16 and the piercing head 17 downwards. The connecting rod 16 increases the depth of penetration into the ground and prevents the screw 14 from entering the geotechnical soil, thus allowing the piercing head 17 and connecting rod 16 to penetrate the soil. Within the soil, the contact area between the base 1 and the rock and soil surface is increased, and the stability of the device is improved. By starting the first motor 10, the output ends of the two first motors 10 rotate, driving the rotating shaft 8 to rotate. The rotating shaft 8 drives the compaction block 9 to rotate. The compaction block 9 makes a circular motion around the axis of the rotating shaft 8. When the compaction block 9 rotates, it will generate a large outward force and drive the compaction frame 7 to move vertically up and down. The two first springs 6 at the bottom and bottom of the connecting plate 5 continuously contract and stretch. The compaction frame 7 drives the second spring 11 and the compaction seat 12 to move up and down. The compaction seat 12 repeatedly and continuously compacts the rock and soil.
