Description

Technical Field

[0001] The present invention relates to the technical field of foundation ramming, and particularly to a foundation stable ramming device for engineering construction. Background Art

[0002] During the construction process, it is often necessary to operate on the foundation. During the foundation construction process, it is necessary to stably ram the soil of the foundation, that is, to compact the soil. When the ramming device continuously hits the ground, the generated particulate dust pollutes the surrounding environment. Moreover, when workers are operating, it is extremely easy to inhale particulate dust into the body, which causes damage to the physical health of workers.

[0003] In view of the above problems, the invention patent with the publication number "CN118932975B" discloses a foundation ramming device for building engineering, belonging to the technical field of foundation ramming. It includes a ramming plate, a ramming body is installed on the top of the ramming plate, a dust-proof folding box is installed on the top of the ramming body, a machine body is installed on the top of the dust-proof folding box, a control center is installed on the top of the machine body, a motor is installed at one end of the machine body, a fixed hollow frame is installed at the end of the machine body away from the motor, and a helical gear set is installed at the output end of the motor. The above solution collects dust during the ramming process, which protects the environment and also ensures the physical and mental health of workers. However, this solution reduces dust by first sucking dust and then spraying water. Although it can solve the problem of dust pollution, it cannot clean the ramming components, and cannot moisten the ground to be rammed. The ramming components are prone to large losses during operation. At the same time, it is also impossible to clean the ramming plate. The soil and sundries adhering to the ramming plate are likely to cause the rammed ground to be uneven, resulting in a significant reduction in the ramming effect. Summary of the Invention

[0010] The dust reduction part is composed of a C-shaped pipe, a spray pipe and a spray nozzle, which is used for spraying water to degrade the dust raised when the swinging tamping part is working. The C-shaped pipe is fixedly installed above the front end of the front frame. Several spray pipes are arranged on the C-shaped pipe and connected with it. Each spray nozzle is respectively arranged at the end of the spray pipe. A water delivery mechanism for delivering water to the C-shaped pipe is installed on the wall of the front frame.

[0021] 1. The swing plate of the swing tamping part designed by the present invention realizes reciprocating swing through the driving mechanism of the fixed shaft, torsion spring, semi-gear and full-gear, driving the heavy impact block to repeatedly hammer the foundation. Compared with the traditional single tamping method, this design can make the foundation receive high-frequency and multi-angle tamping forces, significantly improving the density and stability of the foundation and laying a solid foundation for subsequent building construction;

[0022] 2. The present invention forms a complete spray system by setting the C-shaped pipe fitting, spray pipe and spray nozzle of the dust reduction part. The water delivery mechanism uses the meshing transmission of the semi-gear and the rack to accurately deliver the water in the connection box to the spray system. When the swing tamping part works, water mist is sprayed in time through the spray nozzle, effectively degrading the raised dust and reducing dust pollution. It not only protects the construction environment but also reduces the risk of workers inhaling dust, ensuring the physical health of workers;

[0023] 3. The cleaning part set by the present invention drives the reciprocating lead screw through a double-shaft motor, driving the arc-shaped scraper to reciprocate, and can timely remove the soil adhered to the surface of the compaction roller, avoiding unevenness of the compacted ground caused by the accumulation of dirt and ensuring uniform and stable compaction effect of the foundation.

[0024] 4. The setting of the pressure increasing valve enables the water ejected from the spray nozzle to have a certain water pressure, which can simultaneously clean the swing tamping part and moisten and soften the ground of the foundation. When the swing tamping part operates, the pre-softened ground enables the heavy impact block to penetrate deeper into the foundation, significantly improving the tamping depth and density. Compared with traditional direct tamping, the bearing capacity of the foundation can be improved, providing a more stable support for the subsequent building structure. Description of the Drawings

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1

[0034] Refer to Figure 1-6 , a foundation stabilizing and ramming device for engineering construction, including a ramming vehicle 1, a connecting box body 3, a front frame 4, a compaction roller 5, a cleaning part and a swinging ramming part,

[0035] The compaction roller 5 is rotatably connected between the inner walls of the front frame 4, the connection box 3 is integrally arranged with the front frame 4 and the interior thereof is a cavity for storing water, a cab 2 is arranged at the upper end of the compaction vehicle 1, and the bottom of the cab 2 is fixedly connected to the connection box 3 through a connection member 28;

[0036] The cleaning part is composed of an arc scraper 26, a reciprocating screw 24, a screw nut 25 and a bent rod 27, which is used to clean the dirt and soil adhered to the compaction roller 5. The arc scraper 26 is preset on one side of the upper end of the compaction roller 5 and a gap is reserved. A pair of fixed plates 13 are symmetrically fixedly connected to the upper end of the front frame 4. A dual-axis motor 14 is fixedly installed on one side of the fixed plate 13, and the output shaft of the dual-axis motor 14 is fixedly connected to the reciprocating screw 24; the reciprocating screw 24 is rotatably connected between a pair of fixed plates 13, the screw nut 25 is threadedly connected to the reciprocating screw 24, and the bent rod 27 is fixedly connected between the screw nut 25 and the arc scraper 26.

[0037] The swinging tamping part is composed of a cylindrical component 7, an arc-shaped pendulum 8, a heavy striking block 9 and a pair of swinging plates 6, which are used for repeatedly hammering and tamping the foundation. The cylindrical component 7 and the arc-shaped pendulum 8 are integrally arranged, and a plurality of heavy striking blocks 9 are evenly distributed on the lower end surface of the arc-shaped pendulum 8; a pair of swinging plates 6 are symmetrically rotatably connected to the front end of the front frame 4 through a fixed shaft 22, and a torsion spring 23 is arranged between the fixed shaft 22 and the front frame 4, and a driving mechanism for driving the swinging tamping part to swing back and forth is installed on the wall of the front frame 4.

[0038] The driving mechanism includes a half gear 11 and a full gear 10. Both the half gear 11 and the full gear 10 are rotationally connected to the wall of the front frame 4. The full gear 10 is coaxially fixedly connected to the fixed shaft 22. The dual-axis motor 14 is transmission-connected to the half gear 11 through a transmission mechanism.

[0039] The transmission mechanism includes a driving wheel 15 and a driven wheel 16 . The driving wheel 15 is coaxially fixedly connected to the output shaft of the dual-axis motor 14 . The driven wheel 16 is coaxially fixedly connected to the half gear 11 . The driving wheel 15 and the driven wheel 16 are connected via a belt 17 .

[0040] In this embodiment, after the equipment is started, the operator controls the equipment to move to the area to be compacted in the cab 2. At this time, the dual-axis motor 14 starts to work, as the power source for multiple functions of the equipment, and its output shaft drives two different transmission paths to operate.

[0041] During the operation of the cleaning section, one of the output shafts of the dual-axis motor 14 is fixedly connected to the reciprocating lead screw 24, driving the reciprocating lead screw 24 to rotate between a pair of fixed plates 13. Since the lead screw nut 25 is threadedly connected to the reciprocating lead screw 24, according to the principle of spiral transmission, the lead screw nut 25 will make a reciprocating linear motion along the axis direction of the lead screw under the rotation of the reciprocating lead screw 24. Through the bent rod 27, the motion of the lead screw nut 25 is transmitted to the arc-shaped scraper 26, causing the arc-shaped scraper 26 to make a reciprocating motion on one side of the upper end of the compaction roller 5. When the compaction roller 5 rotates between the inner walls of the front frame 4 to initially compact the ground, the arc-shaped scraper 26 can timely scrape off the dirt and soil adhered to the surface of the compaction roller 5, avoiding the unevenness of the compacted ground caused by the accumulation of dirt, and ensuring the uniformity and stability of the foundation compaction effect.

[0042] The operation of the swing tamping section is based on the other power output path of the dual-axis motor 14. This output shaft of the dual-axis motor 14 is coaxially and fixedly connected to the driving wheel 15, the driving wheel 15 is drivingly connected to the driven wheel 16 through the belt 17, and the driven wheel 16 is coaxially and fixedly connected to the half gear 11. Therefore, when the dual-axis motor 14 rotates, the half gear 11 is driven to rotate through belt drive. The half gear 11 meshes with the full gear 10, the full gear 10 is coaxially and fixedly connected to the fixed shaft 22, and the fixed shaft 22 is symmetrically and rotatably connected to a pair of swing plates 6. When the half gear 11 rotates, it will drive the full gear 10 to rotate intermittently, and then cause the fixed shaft 22 to rotate, and the swing plates 6 on the fixed shaft 22 will swing accordingly. The cylindrical member 7 and the arc-shaped pendulum 8 integrally provided on the swing plate 6, as well as the heavy impact blocks 9 evenly distributed on the lower end surface of the arc-shaped pendulum 8, will repeatedly hammer the foundation under the drive of the swing plate 6. When the half gear 11 is disengaged from the full gear 10, the torsion spring 23 provided between the fixed shaft 22 and the front frame 4 comes into play, pushing the swing plate 6 to reset, enabling the swing plate 6 to make the next swing, realizing high-frequency and multi-angle tamping of the foundation, and effectively improving the density and stability of the foundation.

[0043] Embodiment 2

[0044] Refer to Figure 1-6, different from the first embodiment, the dust-removing part is composed of a C-shaped pipe fitting 29, a spray pipe 30 and a spray nozzle 31, and is used for spraying water to degrade the dust raised when the swing ramming part works. The C-shaped pipe fitting is fixedly installed above the front end of the front frame 4. A plurality of spray pipes 30 are arranged on and communicated with the C-shaped pipe fitting 29. Each spray nozzle 31 is respectively arranged at the end of the spray pipe 30. A water conveying mechanism for conveying water to the C-shaped pipe fitting 29 is installed on the wall of the front frame 4. The water conveying mechanism includes a pump water tank 18, a piston member 33, a water inlet pipe 20 and a water outlet pipe 21. The pump water tank 18 is fixedly installed on the wall of the front frame 4. The piston member 33 is hermetically and slidably connected between the inner walls of the pump water tank 18. The water inlet pipe 20 is communicated between the pump water tank 18 and the connection box body 3. The water outlet pipe 21 is communicated between the pump water tank 18 and the C-shaped pipe fitting. A pushing mechanism for pushing the piston member 33 to slide reciprocally is installed on the wall of the front frame 4.

[0045] The pushing mechanism includes a rack 12, a push rod 32 and a return spring 19. The rack 12 is slidably connected to the wall of the front frame 4 and meshes with the half gear 11. The push rod 32 is fixedly connected between the rack 12 and the piston member 33. The return spring 19 is elastically connected between the rack 12 and the pump water tank 18.

[0046] A one-way valve that only allows water to flow from the connection box body 3 to the pump water tank 18 is installed in the water inlet pipe 20. A one-way valve that only allows water to flow from the pump water tank 18 to the C-shaped pipe fitting is installed in the water outlet pipe 21.

[0047] In this embodiment, while the swinging ramming part is working, the dust suppression part also operates synchronously. During the rotation of the semi-gear 11, it will also engage with the rack 12. The rack 12 is slidably connected to the wall of the front frame 4, and is fixedly connected to the piston member 33 which is slidably and sealingly connected between the inner walls of the pump water tank 18 through a push rod 32. A return spring 19 is elastically connected between the rack 12 and the pump water tank 18. When the semi-gear 11 rotates and engages with the rack 12, it drives the rack 12 to slide on the wall of the front frame 4, and pushes the piston member 33 to reciprocate between the inner walls of the pump water tank 18 through the push rod 32. The water inlet pipe 20 connects the pump water tank 18 and the connection box 3, and a one-way valve that only allows water to flow from the connection box 3 to the pump water tank 18 is installed in the water inlet pipe 20; the water outlet pipe 21 connects the pump water tank 18 and the C-shaped pipe fitting 29, and a one-way valve that only allows water to flow from the pump water tank 18 to the C-shaped pipe fitting 29 is installed in the water outlet pipe 21. Under the reciprocating motion of the piston member 33, the water in the connection box 3 is sequentially transported to the C-shaped pipe fitting 29 through the water inlet pipe 20, the pump water tank 18, and the water outlet pipe 21. A plurality of spray pipes 30 communicating with it are provided on the C-shaped pipe fitting 29, and the spray nozzles 31 at the ends of the spray pipes 30 spray the water in the form of water mist. Since a pressure increasing valve is installed on the spray pipe 30, the sprayed water has a certain water pressure. On the one hand, it can effectively degrade the dust raised when the swinging ramming part works and reduce dust pollution; on the other hand, it can also clean the components of the swinging ramming part, and at the same time moisten and soften the ground base, so that the heavy impact block 9 can penetrate deeper when ramming the ground base, further improving the ramming depth and density.

[0048] Embodiment Three

[0049] The difference from Embodiments One and Two is that a pressure increasing valve is installed on the spray pipe 30, the preset value of the pressure increasing valve is controlled and changed by an existing program, and a wear-resistant bearing is provided at the connection between the swing plate 6 and the fixed shaft 22. The outer ring of the wear-resistant bearing is fixedly connected to the swing plate 6, and the inner ring is fixedly connected to the fixed shaft 22.

[0050] In this embodiment, during the operation of the dust suppression part, since the preset value of the pressure increasing valve installed on the spray pipe 30 can be controlled and changed by an existing program, the equipment can flexibly adjust the water pressure sprayed by the spray nozzle 31 according to different construction scenarios and requirements. For example, in a harsh construction environment with a large amount of dust, the operator can increase the preset value of the pressure increasing valve through the program, so that the spray nozzle 31 sprays high-pressure water mist, enhancing the dust suppression effect and more effectively suppressing a large amount of dust raised during the operation of the swinging ramming part; while in a working scenario with a higher requirement for the wetness of the ground base, appropriately increasing the water pressure, the water mist can not only better moisten and soften the ground base, but also more thoroughly clean the components of the swinging ramming part, further improving the ramming depth and density of the heavy impact block 9 when ramming the ground base. By controlling the pressure increasing valve through the program, the intelligent adjustment of the equipment function is realized, and the adaptability and efficiency of the construction are improved.

[0051] In terms of the swinging ramming part, a wear-resistant bearing is provided at the connection between the swinging plate 6 and the fixed shaft 22. The outer ring of the wear-resistant bearing is fixedly connected to the swinging plate 6, and the inner ring is fixedly connected to the fixed shaft 22. This improvement greatly enhances the rotational performance of the swinging plate 6. During the operation of the equipment, the double-shaft motor 14 drives the half gear 11 to rotate through belt transmission. The half gear 11 meshes with the full gear 10 to rotate the fixed shaft 22, thereby driving the swinging plate 6 to swing reciprocally and driving the heavy impact block 9 to ram the foundation. In the traditional connection method, under long-term high-frequency swinging, large friction is likely to occur between the swinging plate 6 and the fixed shaft 22, resulting in serious wear of the components, affecting the service life of the equipment and the ramming effect. The application of the wear-resistant bearing, with its low friction coefficient and high wear resistance, significantly reduces the frictional resistance between the swinging plate 6 and the fixed shaft 22, making the swinging of the swinging plate 6 smoother and more stable, and reducing the energy loss caused by friction. At the same time, the wear-resistant bearing can withstand large radial and axial loads, ensuring the reliability of the swinging ramming part under long-term and high-intensity work, reducing the maintenance frequency and repair cost of the equipment, extending the overall service life of the equipment, and ensuring the continuous and efficient progress of the foundation ramming operation.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
