Description

Technical Field

[0001] This utility model relates to the field of vibratory stone crushing pile technology, specifically a vibration damping connection mechanism for a vibratory compactor. Background Technology

[0002] Vibro-compacted stone piles are used in composite foundations. They do not significantly improve drainage, consolidation, or soil densification between the piles. Instead, they replace the original foundation soil with stone piles, reinforcing the soil within the pile body. Because the piles are stiffer than the surrounding soil, ground stress is concentrated on the stone piles, reducing additional stress on the surrounding soil, thus increasing the overall bearing capacity of the composite foundation and reducing compressibility.

[0003] In existing building foundation treatment technologies, when the natural foundation or artificial backfill site contains large-diameter materials such as boulders, gravel, and crushed stone, the vibration damper is subjected to multiple influences of tension, compression, and shear forces during the two-point resonance vibratory compaction method. This can easily lead to situations such as drill bit jamming or burying during hole drilling and pile making, preventing the vibratory compactor from reaching the designed depth. Furthermore, during the upward extraction process, drill bit jamming can easily occur, causing the guide pipe to break and the vibratory compactor to be lost. Therefore, a vibratory hammer with vertical vibration force is added to the conventional vibratory compaction method during construction.

[0004] However, the above solution addresses the multiple effects of tension, compression and shear on the shock absorber, as well as the problems of stuck drill and buried drill during the drilling and pile making process, which prevent the vibratory compactor from reaching the designed depth. During the upward pulling process, the drill is also prone to getting stuck, causing the guide tube to break and the vibratory compactor to be lost. However, the vertical high-frequency vibration of the vibratory hammer can damage the shock absorber, thereby damaging the equipment and hindering the normal progress of construction. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing connection mechanism for a vibratory hammer, which has the feature of preventing the vertical high-frequency vibration of the vibratory hammer from damaging the shock absorber and thus causing equipment damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing connection mechanism for a vibratory impactor, comprising a vertical vibratory hammer, wherein the vertical vibratory hammer is provided with a buffer mechanism, the buffer mechanism comprising a buffer frame, wherein the buffer frame has a buffer cavity, wherein the buffer cavity is fixedly connected to a plurality of elastic elements, wherein the plurality of elastic elements are fixedly connected to a sliding column, wherein the sliding column has a plurality of second through holes, wherein each of the plurality of second through holes is slidably connected to a second limiting rod, and wherein the sliding column is fixedly connected to a second fixing plate.

[0007] To prevent the sliding column from rotating inside the buffer cavity, as a preferred shock-absorbing connection mechanism of the vibratory impactor of this utility model, the sliding column is slidably connected to the buffer cavity, the second limiting rod is fixedly connected to the buffer cavity, and the second fixed plate is fixedly connected to the vertical vibratory hammer.

[0008] To facilitate the vertical movement of the lifting column within the lifting cavity, the preferred shock-absorbing connection mechanism for a vibratory impactor of this invention includes a lifting mechanism. The lifting mechanism comprises a lifting frame with a lifting cavity. An electric telescopic rod is installed in the lifting cavity, and the output end of the electric telescopic rod is fixedly connected to the lifting column.

[0009] In order to enable the lifting column to rise and fall vertically inside the lifting cavity, as a preferred shock-absorbing connection mechanism of the vibratory impactor of this utility model, the lifting column is slidably connected to the lifting cavity, and the lifting column is fixedly connected to a first fixed plate, which is fixedly connected to a buffer frame.

[0010] To prevent the lifting column from rotating inside the lifting cavity, as a preferred shock-absorbing connection mechanism of the vibratory impactor of this utility model, the lifting column is provided with multiple first through holes, and each of the multiple first through holes is slidably connected to a first limiting rod, which is fixedly connected to the lifting cavity.

[0011] In order to enable the sliding rods to move closer or further apart, the preferred shock-absorbing connection mechanism of the vibratory impactor of this utility model is a lifting mechanism with a support mechanism. The support mechanism includes a receiving frame and two mutually symmetrical first hinge blocks. The receiving frame is fixedly connected to the main body of the device. The receiving frame has a receiving cavity with a sliding groove. A servo motor is installed in the receiving frame. The output end of the servo motor is fixedly connected to a positive and negative threaded rod. Both first hinge blocks have threaded holes, which are threadedly connected to the positive and negative threaded rods.

[0012] In order to fix the two support plates to the inside of the pile hole, as a preferred shock-absorbing connection mechanism of the vibratory compactor of this utility model, each of the two first hinge blocks is hinged to two mutually symmetrical hinge rods, and each of the two hinge rods is hinged to a second hinge block. The second hinge block is fixedly connected to a sliding rod, which passes through a sliding groove and is fixedly connected to a support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the elasticity of the elastic element to drive the sliding column to slide up and down inside the buffer cavity during vertical vibratory hammer operation. Simultaneously, it allows the second limiting rod to slide inside the second through hole, preventing the sliding column from rotating inside the second through hole and damaging the elastic element. This effectively buffers the vibration force generated by the vertical vibratory hammer, achieving the purpose of efficiently buffering the vertical impact force of the vertical vibratory hammer. It solves the problem that the high-frequency vertical vibration of the vibratory hammer can damage the shock absorber, leading to equipment damage and hindering normal construction. This ensures the safety of the device.

[0015] 2. This utility model controls the rotation of a servo motor, which in turn drives the forward and reverse threaded rods to rotate. This causes the two first hinge blocks to move closer together, while the two symmetrical second hinge blocks move further apart. Simultaneously, this causes the two symmetrical sliding rods and the two symmetrical support plates to move further apart, and the two symmetrical support plates to be firmly fixed inside the pile hole. This ensures the device is perpendicular to the pile hole, preventing the device from tilting due to pressure from gravel, which would prevent the vertical vibratory hammer from impacting the gravel vertically and weaken the effect of dispersing accumulated gravel. This achieves practicality in the use of this device. By controlling the extension of the electric telescopic rod, the servo motor is driven to rise vertically inside the lifting chamber, thereby driving the first fixed plate to rise vertically and simultaneously driving the vertical vibratory hammer to rise vertically. This allows the vertical vibratory hammer to continuously rise and disperse accumulated gravel, preventing the hoisting rope from being immobilized by accumulated gravel, and preventing the vertical vibratory hammer from only impacting the gravel around itself. This also prevents the vertical vibratory hammer from impacting higher-level accumulated gravel after the gravel around it has been dispersed and broken off. This also achieves practicality in the use of this device. Attached Figure Description

Detailed Implementation

[0022] Please see Figures 1 to 5 A shock-absorbing connection mechanism for a vibratory impactor includes a vertical vibratory hammer 5. The vertical vibratory hammer 5 is provided with a buffer mechanism 4. The buffer mechanism 4 includes a buffer frame 401. The buffer frame 401 has a buffer cavity 402. The buffer cavity 402 is fixedly connected to a plurality of elastic elements 403. The plurality of elastic elements 403 are fixedly connected to a sliding column 404. The sliding column 404 has a plurality of second through holes 405. The plurality of second through holes 405 are slidably connected to a second limiting rod 406. The sliding column 404 is fixedly connected to a second fixing plate 407. The sliding column 404 is slidably connected to the buffer cavity 402. The second limiting rod 406 is fixedly connected to the buffer cavity 402. The second fixing plate 407 is fixedly connected to the vertical vibratory hammer 5.

[0023] In this embodiment, the elastic element 403 is preferably made of a spring. Through the elastic action of the elastic element 403, during the vibration operation of the vertical vibratory hammer 5, it can drive the sliding column 404 to slide up and down inside the buffer cavity 402, while simultaneously causing the second limiting rod 406 to slide inside the second through hole 405. This prevents the sliding column 404 from rotating inside the second through hole 405 and damaging the elastic element 403, thereby buffering the vibration force generated by the vertical vibratory hammer 5. This achieves the purpose of efficiently buffering the vertical impact force of the vertical vibratory hammer 5, solving the problem that the high-frequency vertical vibration of the vibratory hammer can damage the shock absorber, leading to equipment damage and hindering normal construction. This ensures the safety of the device's use.

[0024] As a technical optimization of this utility model, the buffer mechanism 4 is provided with a lifting mechanism 3. The lifting mechanism 3 includes a lifting frame 301, the lifting frame 301 has a lifting cavity 302, the lifting cavity 302 is equipped with an electric telescopic rod 303, the output end of the electric telescopic rod 303 is fixedly connected to a lifting column 304, the lifting column 304 is slidably connected to the lifting cavity 302, the lifting column 304 is fixedly connected to a first fixed plate 307, the first fixed plate 307 is fixedly connected to the buffer frame 401, the lifting column 304 has multiple first through holes 305, each of the multiple first through holes 305 is slidably connected to a first limiting rod 306, the first limiting rod 306 is fixedly connected to the lifting cavity 302.

[0025] In this embodiment: The electric telescopic rod 303 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources. By controlling the extension of the electric telescopic rod 303, the servo motor 204 is driven to rise vertically inside the lifting cavity 302, thereby driving the first fixed plate 307 to rise vertically. At the same time, the vertical vibrating hammer 5 is driven to rise vertically, so that the vertical vibrating hammer 5 can continuously rise and disperse the accumulated gravel. This avoids the problem that the hoisting rope of this device cannot move due to the accumulation of gravel. The vertical vibrating hammer 5 can only impact the gravel around itself. After the gravel around the vertical vibrating hammer 5 is dispersed and falls off, it cannot impact the gravel accumulated at higher levels. This realizes the practicality of this device.

[0026] As a technical optimization of this utility model, the lifting mechanism 3 is provided with a support mechanism 2. The support mechanism 2 includes a receiving frame 201 and two mutually symmetrical first hinge blocks 206. The receiving frame 201 is fixedly connected to the main body 1 of the device. The receiving frame 201 has a receiving cavity 202. The receiving cavity 202 has a sliding groove 203. The receiving frame 201 is equipped with a servo motor 204. The output end of the servo motor 204 is fixedly connected to a positive and negative threaded rod 205. Both first hinge blocks 206 have threaded holes 207. The threaded holes 207 are threadedly connected to the positive and negative threaded rods 205. Both first hinge blocks 206 are hinged to two mutually symmetrical hinge rods 208. Both hinge rods 208 are hinged to a second hinge block 209. The second hinge block 209 is fixedly connected to a sliding rod 210. The sliding rod 210 passes through the sliding groove 203 and is fixedly connected to a support plate 211.

[0027] In this embodiment: the servo motor 204 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources. Here, the positive and negative threaded rods 205 are threaded to two symmetrical threaded holes 207 respectively. By controlling the rotation of the servo motor 204, the positive and negative threaded rods 205 are driven to rotate, so that the two first hinge blocks 206 move closer to each other, thereby causing the two symmetrical second hinge blocks 209 to move away from each other. At the same time, the two symmetrical sliding rods 210 are driven away from each other, and the two symmetrical support plates 211 are driven away from each other. The two symmetrical support plates 211 are then pressed and fixed inside the pile hole, making the device perpendicular to the pile hole. This avoids the problem that the upper part of the device is tilted due to the compression of the crushed stone, and the vertical vibrating hammer 5 cannot vertically impact the crushed stone, thus weakening the effect of dispersing the accumulated crushed stone. This realizes the practicality of the device.

[0028] Working principle: When the vertical vibratory hammer 5 is vibrating, the elasticity of the elastic element 403 causes the sliding column 404 to slide up and down inside the buffer cavity 402, while the second limiting rod 406 slides inside the second through hole 405, preventing the sliding column 404 from rotating inside the second through hole 405 and damaging the elastic element 403. This buffers the vibration force generated by the vertical vibratory hammer 5, achieving the purpose of efficiently buffering the vertical impact force of the vertical vibratory hammer 5. When the upper part of the device is tilted due to the pressure of crushed stone, and the vertical vibratory hammer 5 cannot vertically impact the crushed stone, weakening the effect of dispersing the accumulated crushed stone, the servo motor 204 is controlled to rotate, which in turn drives the positive and negative threaded rods 205 to rotate, causing the two first hinge blocks 206 to move closer to each other, thereby causing the two symmetrical second hinge blocks 209 to move away from each other. When the two symmetrical sliding rods 210 move away from each other, the two symmetrical support plates 211 also move away from each other, and the two symmetrical support plates 211 are pressed and fixed inside the pile hole, making the device perpendicular to the pile hole, thus achieving the purpose of the device being quickly and vertically supported inside the pile hole; when the pile hole is filled with gravel and the hoisting rope of the device cannot move, and the gravel around the vertical vibrating hammer 5 is scattered and cannot impact the gravel piled up at a higher position, the electric telescopic rod 303 is extended by controlling it, which in turn drives the servo motor 204 to rise vertically inside the lifting chamber 302, thereby driving the first fixed plate 307 to rise vertically, and at the same time driving the vertical vibrating hammer 5 to rise vertically, so that the vertical vibrating hammer 5 can continuously rise and disperse the piled gravel, thus achieving the purpose of the device driving the vertical vibrating hammer 5 to lift and lower.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
