Description

Technical Field

[0001] This utility model relates to the field of foundation grouting technology, specifically to a vibration auxiliary device for foundation grouting. Background Technology

[0002] In foundation engineering construction, grouting is a crucial step in enhancing the bearing capacity and structural stability of the foundation. Its core requirement is to ensure that the grout evenly fills the foundation gaps, preventing insufficient foundation strength due to residual air bubbles and voids. Currently, vibration-assisted equipment is often used to enhance the fluidity of the grout. However, existing vibration-assisted devices have significant limitations: Firstly, the devices have poor compatibility with the grouting pipes of external grouting equipment. Most devices can only match grouting pipes of specific diameters. When changing to different models of grouting equipment during construction, special clamps or the entire vibration device must be replaced, increasing equipment procurement costs and delaying construction progress due to frequent replacement of parts. Secondly, existing devices lack an effective counterweight balance structure. The grouting pipe itself has a certain weight, and during vibration operations, the center of gravity shifts, causing the device to tip over. This not only affects the continuity of grouting operations but may also cause equipment damage or personnel safety hazards.

[0003] Meanwhile, the clamping structure of existing vibration auxiliary devices is mostly rigidly fixed. When clamping the grouting pipe, uneven force can easily damage the outer wall of the pipe, shortening the service life of the grouting pipe. Moreover, the vibration transmission process lacks a buffer design. The impact force generated by the vibrator during operation can be directly transmitted to the device base and surrounding structure, causing the base to loosen, the parts to wear faster, and reducing the overall stability and service life of the device. Utility Model Content

[0004] The problem this utility model aims to solve is to provide a vibration auxiliary device for foundation grouting. This utility model has strong adaptability and high versatility. Through the adaptation mechanism, it can flexibly match different types of grouting pipes. Rotating the adjusting component can drive the arc-shaped rubber pressure plate to move along the guide rod. Together with the first rubber pad and the second rubber pad, it forms multiple fitting clamps. There is no need to replace the special clamps. It can adapt to grouting pipes of different diameters, effectively reducing the equipment adaptation cost. It can be reused in various grouting equipment combination construction scenarios, thus improving the applicability of the device.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a vibration auxiliary device for foundation grouting, including a vibrator, a first fixed plate, a first rubber pad, a second fixed plate, a second rubber pad, a locking member, a mounting base, and a tension spring. The vibrator is connected to the mounting base through several tension springs. The vibrator is used to assist external grouting equipment in grouting. The first fixed plate is fixed to the vibrator by bolts. The first rubber pad is adhered to the inner wall of the first fixed plate. The second fixed plate is hinged to the first fixed plate. The second rubber pad is adhered to the inner wall of the second fixed plate. The locking member is threadedly connected to the second fixed plate and threadedly connected to the first fixed plate. It also includes an adapter mechanism and a counterweight mechanism. The adapter mechanism is used to adapt to the grouting pipes of different models of external grouting equipment. The counterweight mechanism is used to provide counterweight support for the vibrator.

[0006] More preferably, the first fixing plate and the second fixing plate are used together to clamp the grouting pipe of the external grouting equipment.

[0007] More preferably, the adapter mechanism includes a rubber pressure plate, a guide rod, and an adjusting component. The rubber pressure plate is slidably connected to the second fixed plate via symmetrically arranged guide rods, and the adjusting component is rotatably connected to the back of the rubber pressure plate. The adjusting component is threadedly connected to the second fixed plate.

[0008] More preferably, the rubber pressure plate is arc-shaped to fit the grouting pipe of the external grouting equipment.

[0009] More preferably, the counterweight mechanism includes a mounting frame, a counterweight block, and a limiting member. The mounting frame is rotatably connected to the mounting base, the counterweight block is placed inside the mounting frame, and the limiting member is rotatably connected to the mounting base. The limiting member is used to limit the mounting frame.

[0010] More preferably, when in use, the counterweight is located inside the mounting frame, and when not in use, the counterweight is located in the storage slot at the top of the mounting base.

[0011] Compared with the prior art, the advantages of this utility model are: this utility model has strong adaptability and high versatility. Through the adaptation mechanism, it can flexibly match different models of grouting pipes. Rotating the adjusting component can drive the arc-shaped rubber pressure plate to move along the guide rod. Together with the first rubber pad and the second rubber pad, it forms multiple fitting clamps. There is no need to replace the special clamps. It can adapt to grouting pipes of different diameters, effectively reducing the equipment adaptation cost. It can be reused in various grouting equipment combination construction scenarios, thus improving the applicability of the device.

[0012] The structure is stable and safe. The counterweight mechanism supports the counterweight block through the mounting frame. Combined with the fixing effect of the limiting component, it can accurately balance the load of the grouting pipe and prevent the device from tipping over due to the shift of the center of gravity. The vibrator is connected to the mounting base through a tension spring. The tension spring can buffer the vibration impact force and reduce the impact of vibration on the base and surrounding structure. At the same time, the flexible clamping design of the first rubber pad, the second rubber pad and the rubber pressure plate can avoid rigid contact damage to the outer wall of the grouting pipe, taking into account both equipment protection and operational safety.

[0013] The construction quality and efficiency are both improved. The vibration generated by the vibrator can be directly transmitted to the grouting pipe, promoting the flow and diffusion of grout, reducing the residue of air bubbles and voids, and significantly improving the compactness of the foundation grouting. The installation, adjustment and disassembly process of the device is simple and does not require complicated tools. Fixing and adaptation can be completed by simply operating the locking and adjusting parts, which greatly shortens the construction preparation time and improves the work efficiency.

[0024] Example: As shown in the attached figure, a vibration auxiliary device for foundation grouting includes a vibrator 1, a first fixed plate 2, a first rubber pad 21, a second fixed plate 3, a second rubber pad 31, a locking member 4, a mounting base 5, and tension springs 6. The vibrator 1 is connected to the mounting base 5 via four tension springs 6. The vibrator 1 is used to assist external grouting equipment in grouting. The tension springs 6 are used for shock absorption. The first fixed plate 2 is fixed to the vibrator 1 by bolts. The first rubber pad 21 is adhered to the inner wall of the first fixed plate 2. The second fixed plate 3 is hinged to the first fixed plate 2. The second rubber pad 31 is adhered to the inner wall of the second fixed plate 3. The locking member 4 is threadedly connected to the second fixed plate 3. The first fixed plate 2 and the second fixed plate 3 cooperate to clamp the grouting pipe of the external grouting equipment. The locking member 4 is threadedly connected to the first fixed plate 2. It also includes an adapter mechanism 7 and a counterweight mechanism 8. The adapter mechanism 7 is used to adapt to the grouting pipes of different models of external grouting equipment. The counterweight mechanism 8 is used to provide counterweight support for the vibrator 1.

[0025] In this embodiment, specifically, the adapter mechanism 7 includes a rubber pressure plate 71, a guide rod 72, and an adjusting member 73. The rubber pressure plate 71 is slidably connected to the second fixed plate 3 via symmetrically arranged guide rods 72. The rubber pressure plate 71 is arc-shaped to fit the grouting pipe of the external grouting equipment. The adjusting member 73 is rotatably connected to the back of the rubber pressure plate 71 and threadedly connected to the second fixed plate 3. Rotating the adjusting member 73 can adjust the position of the rubber pressure plate 71, thereby clamping the grouting pipes of different models of external grouting equipment. Further, the counterweight mechanism 8 includes a mounting frame 81, a counterweight block 82, and a limiting member 83. The mounting frame 81 is rotatably connected to the mounting base 5. The counterweight block 82 is placed inside the mounting frame 81 and is used to balance the weight of the grouting pipe of the external grouting equipment to prevent the device from tipping over. The limiting member 83 is rotatably connected to the mounting base 5 and is used to limit the mounting frame 81.

[0026] It should be noted that when in use, the counterweight 82 is located inside the mounting frame 81, and when not in use, the counterweight 82 is located in the storage slot at the top of the mounting base 5.

[0027] Before use, adjust the device according to the grouting pipe model of the external grouting equipment. Open the second fixing plate 3, place the grouting pipe on the first rubber pad 21 of the first fixing plate 2, close the second fixing plate 3, and then use the locking piece 4 to thread and fix the first fixing plate 2 and the second fixing plate 3 to initially clamp the grouting pipe. Rotate the adjusting piece 73 of the adapter mechanism 7. Under the guidance of the guide rod 72, the arc-shaped rubber pressure plate 71 will move towards the grouting pipe until the rubber pressure plate 71 and the first rubber pad 21 are engaged and tightly fit the outer wall of the grouting pipe of different diameters, completing the adaptation and fixing. Then rotate the limiting piece 83 to release the limiting of the mounting frame 81, and then rotate the mounting frame 81 to a horizontal state. Place the counterweight 82 into the mounting frame 81. The weight of the counterweight 82 will balance the load of the grouting pipe and prevent the device from tipping over. During grouting operations, vibrator 1 is started. Vibrator 1 is connected to mounting base 5 via tension spring 6. Tension spring 6 can buffer the impact force generated by vibrator 1 during operation, reducing the impact of vibration on the overall stability of the device. The vibration generated by vibrator 1 is transmitted to the grouting pipe, assisting the flow of grout to fill the foundation gaps. When not in use, remove the counterweight 82 from the mounting frame 81 and place it into the storage slot at the top of the mounting base 5. Then rotate the mounting frame 81 to store it in the mounting base 5. Next, rotate the limiting piece 83 to limit the mounting frame 81. Release the locking piece 4 and the adjusting piece 73 to remove the grouting pipe and complete the storage.

[0028] This working method yields significant results. The adapter mechanism 7 can flexibly adapt to different models of grouting pipes without the need to replace special clamps, improving the versatility and flexibility of the device and reducing equipment adaptation costs. The multiple clamping of the first rubber pad 21, the second rubber pad 31, and the rubber pressure plate 71 enhances the stability of the fixation and prevents damage to the outer wall of the grouting pipe during clamping, protecting the equipment. The counterweight mechanism 8 balances the weight through the counterweight block 82, effectively preventing the device from tipping over due to uneven load on the grouting pipe, thus improving safety during operation. The vibration assistance of the vibrator 1 promotes uniform diffusion of the grout, reduces air bubbles and voids, and improves the density and construction quality of the foundation grouting. The shock absorption design of the tension spring 6 reduces the impact of vibration on the mounting base 5 and surrounding structures, extending the service life of the device. When storing, the counterweight block 82 can be placed in the storage slot, reducing the space occupied by the device and facilitating transportation and storage. The entire operation process is simple and convenient, requiring no complex technology and improving construction efficiency.

This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
