Abstract
Description
Technical Field
[0001] This application relates to the field of hydraulic compaction mechanism technology, and in particular to a segmented hydraulic compaction linkage mechanism. Background Technology
[0002] In the field of building construction, foundation treatment is a key link to ensure the stability and safety of buildings, and compaction is an indispensable and important process in foundation treatment. Segmented hydraulic compaction linkage mechanism is often used in compaction. The segmented hydraulic compaction linkage mechanism has the advantages of high efficiency and uniform compaction effect, which can meet the requirements of modern large-scale building projects for foundation compaction quality and progress.
[0003] When the segmented hydraulic compaction linkage mechanism is in operation, its core power comes from the hydraulic system. Through the extension and retraction of the hydraulic telescopic rod, the first compaction plate moves in a regular manner. When the first compaction plate completes a specific stroke under the drive of the hydraulic telescopic rod, it will generate a strong vibration on the second compaction plate. This vibration force, through a clever force transmission design, can be efficiently transmitted to the second compaction plate, enabling the second compaction plate to perform concentrated and uniform compaction work on the ground. Throughout the process, the movements of the first and second compaction plates are coordinated with each other, forming a tight segmented linkage effect, which not only ensures the compaction force but also improves the continuity and efficiency of the operation.
[0004] However, in actual operation, the existing segmented hydraulic compaction linkage mechanism causes severe impact and friction between the compaction plate and the ground during compaction operations. This results in soil, gravel, and other debris being kicked up, forming dust. This dust, under the influence of airflow at the construction site, easily disperses and adheres to various components of the hydraulic system. Over time, this accumulation leads to increased wear and tear on the hydraulic system, blockage of oil passages, and ultimately affects the normal operation of the hydraulic system. Utility Model Content
[0005] The purpose of this application is to address the problem that dust generated by the segmented hydraulic compaction linkage mechanism mentioned in the background art can affect the hydraulic system during actual operation. This application provides a segmented hydraulic compaction linkage mechanism.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A segmented hydraulic compaction linkage mechanism includes a support frame, a main frame slidably connected inside the support frame, a hydraulic telescopic rod fixed inside the main frame, a first compaction plate fixed to the lower end of the hydraulic telescopic rod, a connecting plate fixed to the lower end of the main frame, a second compaction plate fixed to the lower end of the connecting plate, a connecting frame fixed to the side of the support frame, and a dustproof structure provided between the support frame and the connecting plate.
[0008] By adopting the above technical solution, the hydraulic compaction linkage mechanism connects the connecting frame to the crane in use. The crane then moves the entire hydraulic compaction linkage mechanism to the ground that needs to be compacted. The hydraulic telescopic rod extends and retracts, causing the first compaction plate to rise or fall, working in conjunction with the second compaction plate to compact the ground. During the compaction process, a dustproof structure activates, collecting the dust generated during compaction and thus preventing dust accumulation.
[0009] Furthermore, the dustproof structure includes a collection box fixed around the support frame, a cover plate fixed at the lower end of the collection box, a through hole on the cover plate, a guide pipe fixed at the upper end of the collection box, a connecting pipe fixed at the end of the guide pipe away from the collection box, a diversion pipe fixed at the end of the connecting pipe away from the guide pipe, and multiple horn tubes fixed on the diversion pipe, which are evenly arranged in a straight line.
[0010] By adopting the above technical solution, the dustproof structure can play a dustproof role and reduce the impact of dust on the entire hydraulic system during the ground compaction process.
[0011] Furthermore, the connecting pipe is a plastic corrugated flexible hose.
[0012] By adopting the above technical solution, the plastic corrugated hose has a certain degree of flexibility, which allows the diverter pipe to move with the connecting plate.
[0013] Furthermore, an installation frame is fixed to the upper end of the cover plate, the installation frame is slidably disposed with the collection box, a drive motor is fixed inside the collection box, and a fan blade is fixed to the output end of the drive motor.
[0014] By adopting the above technical solution, the drive motor drives the fan blades to rotate, which generates negative pressure inside the collection box, providing power for collecting dust.
[0015] Furthermore, a collection net is fixed inside the mounting frame, and the collection net is located at the upper end of the fan blade.
[0016] By adopting the above technical solution, the dust entering the collection box will fall onto the collection net, and the dust will be collected through the collection net.
[0017] Furthermore, a barrier mesh is fixed inside the horn tube, and the mesh size of the barrier mesh is larger than that of the collecting mesh.
[0018] By adopting the above technical solutions, the barrier net can block large pieces of gravel and soil, reducing the blockage caused by gravel and soil entering the pipe.
[0019] Furthermore, a connecting post is fixed to the side of the connecting plate, and the end of the connecting post away from the connecting plate is fixedly connected to the diversion pipe.
[0020] By adopting the above technical solution, the connecting column is used to connect the diversion pipe to the connecting plate, so that the diversion pipe can move with the connecting plate.
[0021] Furthermore, the connecting post is corrugated and is an elastic rubber post.
[0022] By adopting the above technical solution, the corrugated elastic rubber column has a certain range of motion, which can improve the connection effect between the diversion pipe and the connecting plate.
[0023] In summary, this application includes at least one of the following beneficial effects;
[0024] 1. In this application, when the ground is compacted using the hydraulic compaction linkage mechanism, the drive motor drives the fan blades to rotate, causing a negative pressure to be generated inside the collection box. Then, under the action of the guide pipe, connecting pipe, and diverting pipe, a negative pressure is generated at the position of the horn tube. The dust generated during the compaction process will enter the collection box under the action of the negative pressure. The dustproof structure can play a dustproof role, realizing the collection of dust generated during the compaction process, effectively reducing the impact of dust spreading everywhere on the normal operation of the entire hydraulic system.
[0025] 2. In this application, the diversion pipe and the connecting plate are connected by a corrugated elastic rubber column, which has a certain range of motion, so that the diversion pipe and the connecting plate form a flexible connection. When the connecting plate is hit by the first tamping plate, the flexible connection makes the connection between the connecting pipe and the connecting plate less likely to break compared with the conventional rigid connection, thereby ensuring the normal operation of the dustproof structure.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0034] This application discloses a segmented hydraulic compaction linkage mechanism.
[0035] Reference Figure 1 and Figure 2 A segmented hydraulic compaction linkage mechanism includes a support frame 1, a main frame 11 slidably connected inside the support frame 1, a hydraulic telescopic rod 12 fixed inside the main frame 11, a first compaction plate 13 fixed at the lower end of the hydraulic telescopic rod 12, a connecting plate 14 fixed at the lower end of the main frame 11, a second compaction plate 15 fixed at the lower end of the connecting plate 14, a connecting frame 16 fixed on the side of the support frame 1, and a dustproof structure 2 provided between the support frame 1 and the connecting plate 14.
[0036] When in use, this hydraulic compaction linkage mechanism needs to be connected to a crane via a connecting frame 16. The crane then moves the entire hydraulic compaction linkage mechanism to the ground to be compacted. The hydraulic telescopic rod 12 is activated, extending and retracting to lower or raise the first compaction plate 13. This causes the main frame 11 to be stressed, moving the second compaction plate 15 downwards within the support frame 1, thereby compacting the ground. During compaction, the dustproof structure 2 works to collect dust generated during the compaction process, effectively reducing the impact of dust on the hydraulic system.
[0037] Reference Figures 2-4The dustproof structure 2 includes a collection box 21 fixed around the support frame 1. A cover plate 22 is fixed to the lower end of the collection box 21. The cover plate 22 is connected to the collection box 21 by bolts. A through hole is opened on the cover plate 22. A guide pipe 23 is fixed to the upper end of the collection box 21. A connecting pipe 24 is fixed to the end of the guide pipe 23 away from the collection box 21. The connecting pipe 24 is a plastic corrugated hose. When the connecting pipe 24 moves with the connecting plate 14, the plastic corrugated hose has a certain expansion and contraction capacity, so as not to obstruct the movement of the connecting pipe 24. A diversion pipe 25 is fixed to the end of the connecting pipe 24 away from the guide pipe 23. Multiple horn pipes 26 are fixed on the diversion pipe 25 and are evenly arranged in a straight line.
[0038] The cover plate 22 is fixed with an installation frame 27 at the upper end. The installation frame 27 is slidably set with the collection box 21. The collection box 21 is fixed with a drive motor 271. The output end of the drive motor 271 is fixed with a fan blade 272.
[0039] In addition, a collection net 273 is fixed inside the mounting frame 27, and the collection net 273 is located at the upper end of the fan blade 272.
[0040] When the hydraulic compaction linkage mechanism is used to compact the ground, the drive motor 271 starts working, driving the fan blade 272 to rotate. The rotation of the fan blade 272 creates a negative pressure inside the collection box 21. Then, under the action of the guide pipe 23, connecting pipe 24, and diverting pipe 25, a negative pressure is created at the position of the trumpet pipe 26. The dust generated during the compaction process enters the inside of the trumpet pipe 26 under the negative pressure, then flows along the trumpet pipe 26 into the inside of the diverting pipe 25, and then sequentially through the connecting pipe 24 and guide pipe 23 into the inside of the collection box 21, finally falling onto the collection net 273. When it is necessary to clean the collection net 273, the cover plate 22 is removed, the mounting frame 27 is taken out from inside the collection box 21, the collection net 273 inside the mounting frame 27 is cleaned, and then it is reinstalled in the collection box 21. The dustproof structure 2 can collect the dust generated during the compaction process, effectively reducing the impact of dust scattering and affecting the normal operation of the entire hydraulic system, thus making the operation of the entire hydraulic compaction linkage mechanism more beneficial.
[0041] Reference Figure 2 and Figure 4 Inside the horn tube 26, there is a barrier net 261, the mesh size of which is larger than that of the collecting net 273.
[0042] During the ground compaction process, the barrier net 261 can block larger pieces of gravel and soil, preventing them from entering the pipe and causing blockages.
[0043] Reference Figure 2 and Figure 5A connecting post 28 is fixed to the side of the connecting plate 14, and the end of the connecting post 28 away from the connecting plate 14 is fixedly connected to the diversion pipe 25.
[0044] Among them, the connecting column 28 is corrugated and is an elastic rubber column.
[0045] The corrugated elastic rubber column has a certain range of motion, which makes the guide pipe 23 and the connecting plate 14 form a flexible connection. When the connecting plate 14 is hit by the first tamping plate 13, the flexible connection makes the connecting pipe 24 and the connecting plate 14 less likely to break compared with the conventional rigid connection, thereby ensuring the normal operation of the dustproof structure 2.
[0046] Working principle: When using this hydraulic compaction linkage mechanism, it needs to be connected to the crane through the connecting frame 16. Then, the crane drives the entire hydraulic compaction linkage mechanism to move to the ground that needs to be compacted. The hydraulic telescopic rod 12 is activated. The extension and retraction of the hydraulic telescopic rod 12 drives the first compaction plate 13 to descend or rise, so that the main frame 11 is subjected to force and drives the second compaction plate 15 to move downward inside the support frame 1, thereby compacting the ground.
[0047] During ground compaction, the drive motor 271 starts working, driving the fan blades 272 to rotate. The rotation of the fan blades 272 creates negative pressure inside the collection box 21. Then, under the action of the guide pipe 23, connecting pipe 24, and diverting pipe 25, negative pressure is created at the location of the horn tube 26. Dust generated during the compaction process enters the horn tube 26 under the negative pressure, then flows through the horn tube 26 into the diverting pipe 25, and then sequentially through the connecting pipe 24 and guide pipe 23 into the collection box 21, finally falling onto the collection net 273. When it is necessary to clean the collection net 273, the cover plate 22 is removed, the mounting frame 27 is taken out from inside the collection box 21, the collection net 273 inside the mounting frame 27 is cleaned, and then it is reinstalled in the collection box 21. The dustproof structure 2 can collect the dust generated during the ground compaction process, effectively reducing the impact of dust dispersion on the normal operation of the entire hydraulic system, thus making the operation of the entire hydraulic compaction linkage mechanism more favorable.
