Description

Technical Field

[0001] The invention relates to the technical field of vibrators, in particular to sea sand backfill vibration compaction equipment. Background Art

[0002] Treatment of sea sand foundations is crucial for various construction projects in coastal areas. Sea sand, with its loose particles and large pores, cannot meet the stability and bearing capacity requirements of construction projects without effective treatment. Existing sea sand backfill vibration compaction equipment has emerged. Its purpose is to rearrange sea sand particles through a specific method, reducing porosity and improving the density and bearing capacity of sea sand foundations. It is widely used in engineering fields such as port construction, land reclamation, and coastal building foundation treatment.

[0003] At present, most common sea sand backfill vibration compaction equipment adopts the vibration method. Its main structure includes a vibrator, a lifting device, and a water supply system. As the core component, the vibrator relies on a motor to drive the eccentric block to generate high-frequency vibrations, which transmits the vibration energy to the surrounding sea sand. The lifting device is used to accurately lift the vibrator to the construction site and control its rise and fall in the sea sand layer. The water supply system supplies water to the vibrator, using high-pressure water flow to assist the vibrator in loosening the sea sand, so that the sand particles are redistributed under the action of vibration and water flow. During the construction process, the vibrator is driven by the lifting device and gradually sinks into the sea sand layer. At the same time, the water supply system is turned on to compact the sea sand through the dual effects of the vibrator's vibration and water flushing.

[0004] However, there are still some problems with the existing technology. During the construction phase, when the vibrator enters the sea sand layer, the structural layer around the vibrator is difficult to break quickly, resulting in greater resistance to entering the sand layer. This not only reduces the vibration efficiency, but also makes it difficult for the vibrator to act evenly on the sea sand, affecting the sea sand compaction effect. For example, in some areas with harder sand, the vibrator often gets stuck and cannot penetrate smoothly. When the vibrator is pulled out, the resistance of the upper sand layer is greater, which easily causes wear on the vibrator and shortens its service life. Therefore, the present invention provides a sea sand backfill vibration compaction device to address the shortcomings of the existing technology. Summary of the Invention

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see the attached Figure 1 -Attached Figure 5An embodiment of the present invention provides a sea sand backfill vibration compaction device, including a hanging plate 1 and four positioning mechanisms. The hanging plate 1 serves as a bearing base, and four bases 2 are fixedly connected to its top. The base 2 supports and installs a vibrator 6. Two U-shaped grooves 3 are provided on the outside of the base 2. The U-shaped grooves 3 provide an installation space for the vibrator 6 so that it can be accurately positioned on the base 2. Two vibration-damping springs 4 are fixedly connected to both sides of the outside of the base 2, and one end of the vibration-damping spring 4 is fixedly connected to a U-shaped plate 5. When the vibrator 6 is working, it will generate strong vibrations. The vibration-damping spring 4 can effectively absorb and buffer these vibrations, reduce the impact on the base 2 and the hanging plate 1, and ensure the stability and service life of the equipment. At the same time, the U-shaped plate 5 also provides an installation basis for the subsequent positioning and connection structure. The vibrator 6 is the core component for realizing the vibration and density of sea sand. One end of the vibrator is fixedly connected to the vibrating head 7. The vibrator 6 will generate high-frequency vibrations after being energized. The vibration is transmitted to the sea sand through the vibrating head 7, so that the sea sand particles are rearranged to achieve a dense effect. A soil-breaking mechanism is provided on the outside of the vibrator 6. The structure includes two mounting blocks 28 and two arc-shaped seats 9. One end of the two mounting blocks 28 is fixedly connected to the outside of the vibrator 6 and is symmetrically distributed with the vibrator 6 as the axis, providing a support point for the arc-shaped seat 9 to install and rotate. The outside of the arc-shaped seat 9 is fixedly connected to a soil-breaking blade 10. One side of the arc-shaped seat 9 is fixedly connected to two connecting pieces 8. The two connecting pieces 8 are rotatably connected to the mounting blocks 28. The outside of the vibrator 6 is slidably connected to a sliding ring 29. The outside of the sliding ring 29 is rotatably connected to two pulling rods 30. One end of the two pulling rods 30 is rotatably connected to the inner side of the two arc-shaped seats 9 respectively. The outer side of the sliding ring 29 is fixedly connected to two fixing plates 31. The contact between the fixing plates 31 and the soil will drive the sliding ring 29 to move, and then drive the two pulling rods 30 to move, so as to realize the closeness and separation of the top ends of the two arc-shaped seats 9. When the equipment starts working, the hanging plate 1 is hung on the crane and the construction area is vibrated. The vibrator 6 descends. At this time, the inclined surfaces of the two arc-shaped seats 9 are squeezed by the sand layer when descending and approach each other. This structural design enables the arc-shaped seat 9 and the earth-breaking blade 10 to easily break the structural layer around the vibrator 6 like a sharp knife, providing vibration The conditions are created for the vibrator 6 to enter the sea sand layer smoothly. When the vibration is completed and the vibrator 6 needs to be pulled out, the upper ends of the two arc-shaped seats 9 are subjected to force, and the two earth-breaking blades 10 can be used to break the upper sand layer. In this way, the resistance when the vibrator 6 is pulled out is greatly reduced, and the vibrator 6 is conveniently taken out of the sea sand layer. One side of the four U-shaped plates 5 is fixedly connected to a positioning seat 11, and the other end of the vibrator 6 is fixedly connected to a clamping seat 13. The outer side of the positioning seat 11 is connected to the positioning seat 2 12 by bolts, and the outer side of the clamping seat 13 is in contact with the inner sides of the positioning seat 11 and the positioning seat 2 12 at the same time.By connecting the positioning seat 11 and the positioning seat 2 12 together by bolts, the clamping seat 13 can be firmly clamped, thereby achieving the positioning and fixation of one end of the vibrator 6, ensuring that the vibrator 6 will not shake or shift during operation; the positioning mechanism includes a combination block 14, the outer side of the combination block 14 is fixedly connected to one side of the other U-shaped plate 5, and a combination block 2 16 is provided on the top of the combination block 14. Two clamping blocks 15 are fixedly connected to the outer side of the vibrator 6, and the interiors of the combination block 14 and the combination block 2 16 are both provided with clamping holes 17. The outer side of the clamping block 15 is clamped on the inner side of the clamping hole 17. This clamping structure further enhances the connection stability between the vibrator 6 and the positioning mechanism. When assembling the vibrator 6, first place the vibrator 6 on the inner side of the U-shaped groove 3, and use conventional bolts to tighten one end of the vibrator 6 to preliminarily fix the position of the vibrator 6. Then, the second assembly block 16 is clamped onto the outside of the vibrator 6, so that the clamping block 15 on the outside of the vibrator 6 is engaged with the clamping hole 17, thereby connecting the vibrator 6 to the first assembly block 14 and the second assembly block 16. Next, two plug-in blocks 19 are fixedly connected to the top of the first assembly block 14, and two slots 18 are provided at the bottom of the second assembly block 16. The outer sides of the plug-in blocks 19 are engaged with the inner sides of the slots 18, further ensuring the accurate connection between the first assembly block 14 and the second assembly block 16. The inner sides of the slots 18 and the interiors of the plug-in blocks 19 are both provided with assembly holes 20. The interiors of the assembly holes 20 are slidably connected to limit pins 21. The limit pins 21 are inserted into the assembly holes 20 to limit the position of the first assembly block 14 and the second assembly block 16, preventing them from separating during operation. Finally, two side plates 22 are provided on the outside of assembly block 14. A mounting groove 23 is defined on one side of the side plates 22. One end of the limit pin 21 engages within the mounting groove 23. Two elastic plates 24 are fixedly connected to the outside of the side plates 22. Anti-slip blocks 25 are fixedly connected to the outside of the elastic plates 24. Two slots 26 are defined on the outside of both assembly block 14 and assembly block 2 16. The elastic plates 24 are inserted into the slots 26 to further position the limit pin 21, completing the assembly of the vibrator 6. To disassemble the vibrator 6, the paddle 27 is moved. The outer side of the paddle 27 engages the outer side of the anti-slip block 25. The paddle 27 is moved to compress the anti-slip block 25, causing the elastic plate 24 to bend. The side plates 22 are then pulled outward, causing the limit pin 21 to disengage from the mounting groove 23, thereby releasing the restriction on the limit pin 21. Next, pull out the limit pin 21 from the combination hole 20, remove the second combination block 16 from the vibrator 6, and finally unscrew the bolt fixing one end of the vibrator 6, so that the vibrator 6 can be easily removed from the equipment.

[0021] Specifically, first, the hanging plate 1 is hung on the crane. With the help of the crane's powerful lifting capacity, the equipment can be accurately lifted to the top of the construction area, laying the foundation for the subsequent vibratory operation. When the equipment descends and begins to vibrate the construction area, the two arc-shaped seats 9 on the outside of the vibrator 6 play a key role. During the descent process, the inclined surface of the arc-shaped seat 9 will be squeezed by the sand layer. Due to its special structural design and the rotational connection with the mounting block 28, the two arc-shaped seats 9 will approach each other. This approaching action allows the earth-breaking blade 10 on the outside of the arc-shaped seat 9 to concentrate its force, just like a sharp wedge, to easily break the structural layer around the vibrator 6, greatly reducing the resistance of the vibrator 6 to enter the sand layer, increasing the speed and efficiency of the vibrator 6 descent, and allowing the vibratory operation to start more smoothly. At the same time, since the structural layer has been broken in advance, the vibrator 6 can act more evenly on the sand layer during the subsequent vibration process, which helps to improve the compaction effect of the sea sand. When the vibrating operation is completed and the vibrator 6 needs to be pulled out of the sand layer, the upper ends of the two arc-shaped seats 9 will be subjected to an upward pulling force. At this time, in conjunction with the two earth-breaking blades 10, they can effectively cut and destroy the upper sand layer, which greatly reduces the resistance of the vibrator 6 from the upper sand layer during the extraction process, avoiding the difficulty in extracting the vibrator 6 due to excessive wrapping of the sand layer on the vibrator 6. Not only that, this design can also protect the vibrator 6 itself, reduce damage during the extraction process, extend the service life of the vibrator 6, facilitate the smooth removal of the vibrator 6, and prepare for the next construction; when assembling the vibrator 6, the first step is to place the vibrator 6 on the inner side of the U-shaped groove 3. The U-shaped groove 3 provides a precise positioning space for the vibrator 6, ensuring that the vibrator 6 can be accurately in the predetermined position, ensuring the stability and accuracy of the entire equipment structure. Next, use a conventional bolt to tighten one end of the vibrator 6. Through the tightening action of the bolt, the vibrator 6 is tightly connected to the base 2 to prevent the vibrator 6 from shaking or displacing during operation, thereby ensuring the normal progress of the vibratory operation. Then, use the second assembly block 16 to clamp the outside of the vibrator 6, so that the clamping block 15 on the outside of the vibrator 6 is engaged with the clamping hole 17 inside the second assembly block 16 and the first assembly block 14. This clamping structure further enhances the connection strength and stability between the vibrator 6 and the positioning mechanism. The close fit between the clamping block 15 and the clamping hole 17 can effectively limit the movement of the vibrator 6 in the horizontal direction, so that the vibrator 6 can transmit the vibration force more stably during operation, thereby improving the vibratory effect. Subsequently, the limit pin 21 is inserted into the assembly hole 20 for limiting. Combination holes 20 are formed inside slots 18 and inserts 19. When inserted, stop pins 21 securely connect assembly blocks 14 and 16, preventing them from moving or separating during the vibratory operation. This limiting feature ensures the overall stability of the positioning mechanism and, consequently, the reliability of vibrator 6 during operation.Finally, the elastic plate 24 is inserted into the slot 26 to limit the position of the limit pin 21. The anti-dropout block 25 on the outside of the elastic plate 24 cooperates with the slot 26 to effectively prevent the limit pin 21 from falling out of the assembly hole 20. This dual-limiting design greatly improves the stability and safety of the entire assembly structure, allowing the vibrator 6 to maintain a stable connection state even during high-intensity vibratory operations, completing the reliable assembly of the vibrator 6. When disassembling the vibrator 6, the paddle 27 is moved. Since the outer side of the paddle 27 fits against the outer side of the anti-dropout block 25, the paddle 27 squeezes the anti-dropout block 25, thereby causing the elastic plate 24 to bend. The bending of the elastic plate 24 eliminates its limiting effect on the limit pin 21. At this time, the side plate 22 is pulled outward, and the limit pin 21 will fall out of the assembly slot 23. After the restriction of the limit pin 21 is released, the limit pin 21 can be pulled out of the assembly hole 20, and then the assembly block 2 16 can be removed from the vibrator 6. Finally, the bolt fixing one end of the vibrator 6 can be unscrewed to easily remove the vibrator 6 from the equipment. This disassembly method is simple and convenient, and can quickly complete the disassembly of the vibrator 6, facilitating operations such as repair, replacement, or transportation of the vibrator 6, thereby improving the maintenance efficiency and flexibility of the equipment.

[0022] Working principle: First, hang the hanging plate 1 on the crane and vibrate the construction area. The inclined surfaces of the two arc-shaped seats 9 will be squeezed by the sand layer when descending and will be close to each other, and the fixed plate 31 will be blocked by the soil, which will cause the sliding ring 29 to move up, and then the two pulling rods 30 will push the upper part of the arc-shaped seat 9 to separate it, and assist the bottom ends of the two arc-shaped seats 9 to move closer, so as to facilitate breaking the structural layer around the vibrator 6. When the vibration is completed and the vibrator 6 is pulled out, the upper ends of the two arc-shaped seats 9 are subjected to force, and the fixed plate 31 will be compressed by the soil to drive the sliding ring 29 to move down, and then the two pulling rods 30 will pull the upper part of the arc-shaped seat 9 to move closer, cooperating with the two breaking blades 10 The upper sand layer can be broken to facilitate the removal of the vibrator 6; in addition, when assembling the vibrator 6, the vibrator 6 is placed on the inner side of the U-shaped groove 3, one end of the vibrator 6 is tightened with a conventional bolt, and then the combination block 21 is clamped on the outside of the vibrator 6, so that the clamping block 15 on the outside of the vibrator 6 is engaged with the clamping hole 17, and then the limit pin 21 is inserted into the combination hole 20 for limiting, and then the elastic plate 24 is inserted into the slot 26 to limit the limit pin 21, and the assembly of the vibrator 6 is completed. When disassembling, the paddle 27 is pushed to squeeze the anti-fall-off block 25 to drive the elastic plate 24 to bend, and then the side plate 22 is pulled outward, so that the vibrator 6 can be easily released from the restriction.

[0023] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
