Description

Technical Field

[0001] The present invention relates to the technical field of vibroflots, and specifically to a vibration compaction device for backfilling with sea sand. Background Art

[0002] In various engineering constructions in coastal areas, the treatment of sea sand foundations is of crucial importance. Sea sand has characteristics such as loose particles and large pores. If not effectively treated, it is difficult to meet the requirements of engineering construction for the stability and bearing capacity of the foundation. Existing vibration compaction devices for backfilling with sea sand have emerged. Their purpose is to rearrange sea sand particles in a specific way, reduce the porosity, and improve the compaction degree and bearing performance of the sea sand foundation, and are widely used in engineering fields such as port construction, land reclamation, and foundation treatment of coastal buildings.

[0003] Currently, common vibration compaction devices for backfilling with sea sand mostly adopt the vibroflotation method. Its main structure includes a vibroflot, a hoisting device, and a water supply system, etc. The vibroflot, as the core component, relies on the motor to drive the eccentric block to generate high-frequency vibration and transmit the vibration energy to the surrounding sea sand. The hoisting device is used to accurately lift and transport the vibroflot to the construction position and control its lifting and lowering in the sea sand layer. The water supply system supplies water to the vibroflot and uses high-pressure water flow to assist the vibroflot in loosening the sea sand, so that the sand grains are redistributed under the action of vibration and water flow. During the construction process, the vibroflot gradually sinks into the sea sand layer driven by the hoisting device, and at the same time, the water supply system is turned on, and the sea sand is compacted through the dual actions of the vibration and water flushing of the vibroflot. However, there are still some problems in the existing technology. During the construction stage, when the vibroflot enters the sea sand layer, it is difficult for the structural layer around the vibroflot to be quickly broken, resulting in a large resistance to entering the sand layer, which not only reduces the vibroflotation efficiency but also makes it difficult for the vibroflot to act evenly on the sea sand, affecting the sea sand compaction effect. For example, in some areas with harder sand quality, the vibroflot often gets stuck and cannot penetrate smoothly. When pulling out the vibroflot, the resistance of the upper sand layer is large, which is easy to cause wear on the vibroflot and shorten its service life. Therefore, the present invention provides a vibration compaction device for backfilling with sea sand to solve the deficiencies existing in the existing technology. Summary of the Invention

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to the attached Figure 1 - attached Figure 5, the embodiment of the present invention provides a vibrating compaction device for backfilling sea sand, which includes a hanging plate 1 and four positioning mechanisms. The hanging plate 1 serves as a bearing foundation, and four pedestals 2 are fixedly connected to its top. The pedestals 2 play a role in supporting and installing the vibroflot 6. Two U-shaped grooves 3 are opened on the outer side of the pedestal 2, and the U-shaped grooves 3 provide an installation space for the vibroflot 6, enabling it to be accurately positioned on the pedestal 2. Two damping springs 4 are fixedly connected to both sides of the outside of the pedestal 2, and one end of each damping spring 4 is fixedly connected to a U-shaped plate 5. When the vibroflot 6 is working, strong vibrations will be generated. The damping springs 4 can effectively absorb and buffer these vibrations, reducing the impact on the pedestal 2 and the hanging plate 1, ensuring the stability and service life of the device. At the same time, the U-shaped plate 5 also provides an installation foundation for subsequent positioning and connection structures. The vibroflot 6 is the core component for realizing the vibration compaction of sea sand. One end of it is fixedly connected to a vibroflot head 7. After the vibroflot 6 is powered on, it will generate high-frequency vibrations, and the vibrations are transmitted to the sea sand through the vibroflot head 7, causing the sea sand particles to rearrange and achieving the compaction effect. A soil-breaking mechanism is arranged on the outer side of the vibroflot 6. This mechanism includes two mounting blocks 28 and two arc-shaped seats 9. One end of the two mounting blocks 28 is fixedly connected to the outer side of the vibroflot 6 and is symmetrically distributed with respect to the vibroflot 6, providing a support point for the installation and rotation of the arc-shaped seats 9. A soil-breaking blade 10 is fixedly connected to the outer side of the arc-shaped seat 9. Two connecting pieces 8 are fixedly connected to one side of the arc-shaped seat 9, and the two connecting pieces 8 are rotatably connected to the mounting blocks 28. A sliding ring 29 is slidably connected to the outer side of the vibroflot 6. Two pull rods 30 are rotatably connected to the outer side of the sliding ring 29. One end of each of the two pull rods 30 is rotatably connected to the inner side of the two arc-shaped seats 9 respectively. Two fixing plates 31 are fixedly connected to the outer side of the sliding ring 29. The contact between the fixing plates 31 and the soil will drive the sliding ring 29 to move, and then drive the two pull rods 30 to move, so as to realize the approach and separation of the tops of the two arc-shaped seats 9. When the device starts to work, the hanging plate 1 is hung on the crane and the construction area is vibrated and compacted. The vibroflot 6 descends. At this time, the inclined surfaces of the two arc-shaped seats 9 will approach each other when being squeezed by the sand layer during the descent. This structural design enables the arc-shaped seats 9 and the soil-breaking blades 10 to easily break through the structural layer around the vibroflot 6 like a sharp knife, creating conditions for the vibroflot 6 to smoothly enter the sea sand layer. When the vibration compaction is completed and the vibroflot 6 needs to be pulled out, the upper ends of the two arc-shaped seats 9 are stressed, and together with the two soil-breaking blades 10, they can break through the upper sand layer, greatly reducing the resistance when the vibroflot 6 is pulled out and facilitating the removal of the vibroflot 6 from the sea sand layer. One side of the four U-shaped plates 5 is fixedly connected to a first positioning seat 11, and the other end of the vibroflot 6 is fixedly connected to a clamping seat 13. The outer side of the first positioning seat 11 is bolted to a second positioning seat 12, and the outer side of the clamping seat 13 is simultaneously in contact with the inner sides of the first positioning seat 11 and the second positioning seat 12.By connecting the positioning seat 11 and the positioning seat 2 12 together by bolts, the clamping seat 13 can be firmly clamped, so as to realize the positioning and fixation of one end of the vibrator 6, and ensure 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 another U-shaped plate 5, and a combination block 2 16 is arranged on the top of the combination block 14. Two clamping blocks 15 are fixedly connected to the outer side of the vibrator 6, and clamping holes 17 are provided inside the combination block 14 and the combination block 2 16. 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 on the outside of the vibrator 6, so that the clamping block 15 on the outside of the vibrator 6 is clamped with the clamping hole 17, and the vibrator 6 is connected with the first assembly block 14 and the second assembly block 16. Then, two plug-in blocks 19 are fixedly connected to the top of the first assembly block 14, and two clamping grooves 18 are provided at the bottom of the second assembly block 16. The outer side of the plug-in block 19 is clamped on the inner side of the clamping groove 18, further ensuring the accurate connection between the first assembly block 14 and the second assembly block 16. The inner side of the clamping groove 18 and the inner side of the plug-in block 19 are both provided with assembly holes 20, and the inner side of the assembly hole 20 is slidably connected with a limit pin 21. The limit pin 21 is inserted into the assembly hole 20 to limit the first assembly block 14 and the second assembly block 16 to prevent them from separating during the working process. Finally, two side plates 22 are arranged on the outer side of the assembly block 14, and a mounting groove 23 is provided on one side of the side plate 22. One end of the limit pin 21 is engaged in the inner side of the mounting groove 23. Two elastic plates 24 are fixedly connected to the outer side of the side plate 22, and an anti-dropping block 25 is fixedly connected to the outer side of the elastic plate 24. Two slots 26 are arranged on the outer side of the assembly block 14 and the assembly block 2 16. The elastic plates 24 are inserted into the slots 26 to further limit the limit pin 21, and the assembly of the vibrator 6 is completed. When the vibrator 6 needs to be disassembled, the paddle 27 is moved, and the outer side of the paddle 27 is fitted with the outer side of the anti-dropping block 25. The anti-dropping block 25 is squeezed by moving the paddle 27, and the elastic plate 24 is driven to bend. Then the side plate 22 is pulled outward to make the limit pin 21 come out of the mounting groove 23, thereby releasing the restriction on the limit pin 21. Next, the limiting pin 21 is pulled out from the assembly hole 20, and then the assembly block 2 16 is removed from the vibrator 6, and finally the bolt fixing one end of the vibrator 6 is unscrewed, and the vibrator 6 can be easily removed from the equipment.

[0020] Specifically, first, the hanging plate 1 is hung on the crane. With the help of the powerful lifting capacity of the crane, 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 starts to vibrate the construction area, the two arc seats 9 on the outside of the vibrator 6 play a key role. During the descent, the inclined surface of the arc seat 9 will be squeezed by the sand layer. Due to its special structural design and the rotation connection with the mounting block 28, the two arc seats 9 will approach each other. This approaching action allows the earth-breaking blade 10 on the outside of the arc seat 9 to concentrate its strength, 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, and improving the speed and efficiency of the vibrator 6 descent, so that the vibratory operation can start more smoothly. At the same time, since the structural layer is broken in advance, the vibrator 6 can act more evenly on the sand layer during the subsequent vibratory 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 pulling process, and avoids the situation where the vibrator 6 is difficult to pull out due to excessive wrapping of the sand layer. Not only that, this design can also protect the vibrator 6 itself, reduce the damage it suffers during the pulling 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 located at 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 combination block 2 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 combination block 2 16 and the combination block 1 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 and improve the vibratory effect. Subsequently, the limit pin 21 is inserted into the combination hole 20 for limiting. The combination hole 20 is formed inside the slot 18 and the insert block 19. After the limit pin 21 is inserted, the combination block 14 and the combination block 2 16 can be firmly connected together to prevent them from relative movement or separation during the vibratory operation. This limit measure ensures the overall stability of the positioning mechanism, thereby ensuring the reliability of the 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 outer side of the elastic plate 24 cooperates with the slot 26 to effectively prevent the limit pin 21 from falling out of the combination hole 20. This double limit design greatly improves the stability and safety of the entire assembly structure, so that the vibrator 6 can maintain a stable connection state even in high-intensity vibrating operations, and completes 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 the outer side of the anti-dropout block 25, the paddle 27 will squeeze the anti-dropout block 25, thereby driving the elastic plate 24 to bend. The bending of the elastic plate 24 makes it disappear 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 groove 23. After the restriction of the limit pin 21 is released, the limit pin 21 can be pulled out from the combination hole 20, and then the combination 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, which is convenient for maintenance, replacement or transportation of the vibrator 6, and improves the maintenance efficiency and flexibility of the equipment.

[0021] 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 stressed, and the fixed plate 31 will be pressed by the soil to drive the sliding ring 29 to move downward, 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 earth-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 outer side of the vibrator 6, so that the clamping block 15 on the outer side 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, and the limit pin 21 is limited to complete the assembly of the vibrator 6. When disassembling, the paddle 27 is pushed to squeeze the anti-slip 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.
