Two limiting blocks are arranged on the left and right sides between the two hanging frames and connected to the hanging frame through bolts. The limiting blocks are installed on both sides of the hanging frame through high-strength bolts, which can ensure sufficient limiting strength. The structure is redesigned and replaced with a bolt form fixation to ensure the convenience of replacement and disassembly, improve the use of limiting, reduce the tearing and falling of damping rubber due to insufficient limiting, and facilitate the observation of the wear and tear of the equipment.

[0004] In view of the related technology in the above, the clamp in the prior art is slidingly matched at the bottom of the vibration box and relies on internal hydraulic components to press the bottom of the vibration box to limit the movement of the clamp.

[0008] Optionally, the control assembly includes a hand wheel, a clamp, a limiting cylinder, and a return spring. One end of the rotating shaft is connected to a rectangular column. The end of the rectangular column is provided with a fixed protruding ring. The hand wheel is provided with an extension column. Four clamps are connected to the end of the extension column. One of the clamps corresponds to the sidewall of one of the rectangular columns. The limiting cylinder is slidably connected to the extension column. The extension column is connected to a fixed ring. The return spring is sleeved on the extension column and located between the fixed ring and the limiting cylinder. When operating, the clamps clamp the fixed protruding ring, the clamps are located in the limiting cylinder, and the extension column is provided with a limiting member for limiting the movement of the limiting cylinder.

[0009] By adopting the above technical solution, during control, the limiting cylinder is moved and the limiting component is used to stop the movement of the limiting cylinder. The return spring is compressed until the clamp is outside the limiting cylinder, and the clamp holds the fixed protrusion ring. During this process, the clamp deforms and moves until it touches the surface of the extension column. The limiting component is released, and the limiting cylinder moves in the opposite direction under the force of the return spring and enters the clamp until the limiting cylinder covers the clamp again. At this time, the handwheel can be turned. The clamp cannot move due to the influence of the limiting cylinder, and the extension column is pressed by the torsional force, causing the rotating column to rotate, thereby achieving the effect of driving the adjustment gear to rotate.

[0010] Optionally, the limiting member is a rotating sleeve, which is sleeved on the extension column and located between the fixed ring and the handwheel. The inner ring wall of the limiting member is provided with a threaded section. When the handwheel is installed, the limiting cylinder is threaded into the limiting member, the clamp is located outside the limiting cylinder, and the return spring is compressed.

[0011] By adopting the above technical solution, when the limiting cylinder is prevented from moving, the limiting cylinder moves, the return spring is compressed until it moves to the position of the limiting component, the limiting component is rotated, and the limiting cylinder is pressed down, so that the limiting component and the limiting cylinder are threadedly engaged, causing the limiting cylinder to move continuously until the clamp is located outside the limiting cylinder, thereby achieving the effect of preventing the limiting cylinder from moving.

[0012] Optionally, the surface of the extension column is provided with a limiting groove, the limiting groove being parallel to the length direction of the extension column, and a limiting block is connected to the limiting cylinder, the limiting block being slidably fitted within the limiting groove.

[0013] By adopting the above technical solution, the movement angle of the limiting cylinder is limited by the cooperation of the limiting block and the limiting groove. At this time, by rotating the limiting component, the limiting component can be threadedly engaged with the limiting cylinder without operating the limiting cylinder, which provides convenience for preventing the movement of the limiting cylinder.

[0014] Optionally, the inlet end of the clamping groove is provided with two guide ramps, which are arranged opposite to each other. The bottom end of the clamp is connected to an extension frame, and the extension frame is provided with an abutting ramp, which is flush with one of the guide ramps.

[0015] By adopting the above technical solution, the cooperation between the guiding slope and the contacting slope is used to facilitate the guidance of the top side wall of the foundation pile into the clamping groove, which provides convenience for the hydraulic vibratory hammer to clamp the foundation pile.

[0016] Optionally, the fixture is provided with a mounting block and a mounting mechanism. The fixture has a stabilizing groove, and the mounting block is connected to a stabilizing flange. The stabilizing flange is embedded in the stabilizing groove. The rotating shaft is rotatably connected to the mounting block. The mounting mechanism includes a voltage stabilizing component for stabilizing one side of the mounting block and a stabilizing component for stabilizing the other side of the mounting block.

[0017] By adopting the above technical solution, large particles of soil can easily adhere to the adjusting gear during on-site construction, causing blockage of its rotation. During installation, the stabilizing flange is inserted into the stabilizing groove, and then the pressure stabilizing component and the stabilizing component are used to secure both sides of the mounting block, restricting its movement and enabling easy installation and removal. The detachable mounting block allows for convenient removal and cleaning of the adjusting gear without needing to clean the entire clamp, thus simplifying clamp maintenance.

[0018] Optionally, the voltage stabilizing assembly includes a fixing frame, a pressure block, and locking bolts. The fixing frame is connected to one side of the mounting block. The bottom end of the fixing frame is provided with an inclined surface, with the reference direction from bottom to top. The thickness of the fixing frame gradually increases. The clamp has a pressure groove. The pressure block is L-shaped. One end of the pressure block passes through the pressure groove from top to bottom and is inserted into the fixing frame. One end of the pressure block is in contact with the inclined surface. The top wall of the pressure block is flush with the top wall of the clamp. Several locking bolts are provided. The locking bolts pass through the pressure block and the clamp and are threaded into the clamp.

[0019] By adopting the above technical solution, when pressing one side of the stabilizing mounting block, the pressure block is inserted into the pressure groove, the bottom end of the pressure block enters the inside of the fixed frame, and the inclined surface is pressed to make the mounting block press against the side wall of the stabilizing groove. Finally, the locking bolt is threaded into the clamp to lock the pressure block, thus achieving the effect of stabilizing one side of the mounting block.

[0020] Optionally, the stabilizing assembly includes a hook plate, a pressure rod, a push block, a limiting rail, and a stabilizing bolt. The clamp end wall has a receiving groove, and the mounting block has a groove. The receiving groove communicates with the groove. The hook plate end has a first waist-shaped groove, and the clamp has a second waist-shaped groove, the length of which is greater than the length of the first waist-shaped groove. A mounting frame is connected to the clamp, and the limiting rail is connected within the mounting frame. The push block is disposed between the mounting frame and the second waist-shaped groove and slidably engages with the limiting rail. The push block is provided with a pushing slope, with the reference direction from bottom to top. The length of the push block gradually increases. A sliding groove is opened on the pushing slope. The sliding groove is a T-shaped groove. The pressure rod is horizontally inserted between the first waist-shaped groove and the second waist-shaped groove. A fixing strip is connected to the end of the pressure rod. The fixing strip is slidably engaged in the sliding groove. The stabilizing bolt is rotatably connected to the mounting frame and threadedly engaged with the push block. When stabilizing the mounting block, the hook plate hooks the groove, and the pressure rod applies pressure to the bottom end of the first waist-shaped groove.

[0021] By adopting the above technical solution, when stabilizing the other side of the installation block, the hook plate is flipped and moved so that it hooks into the groove. Then, the stabilizing bolt is rotated to move the push block. Through the sliding cooperation of the limiting rail and the pressure rod, the pressure rod is lowered until it presses against the bottom of the first waist-shaped groove, thereby limiting the movement of the hook plate and pressing the installation block against the bottom wall of the stabilizing groove, thus achieving the effect of stabilizing the other side of the installation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During operation, based on the pile diameter, the control component rotates the rotating shaft beforehand, causing the adjusting gear to rotate. The adjusting gear and rack mesh, moving the clamp to the designated position and inserting the pile's top sidewall into the clamping groove. During this process, the control component controls the adjusting gear to fine-tune the clamp position, ensuring the pile's top sidewall smoothly enters the groove. The drive component moves the clamping part until the pile's top sidewall is pressed between the fixed part and the clamping part. Hydraulic components then press against the sliding rail, restricting the clamp's movement. A crane is then used to lift the hydraulic vibratory hammer, and the pile is inserted into the foundation hole. Finally, the drive component inside the vibration box is activated, causing the hydraulic vibratory hammer to vibrate, thus completing the pile driving operation. By rotating the rotating shaft and engaging the adjusting gear and rack to drive the clamp, compared to existing technologies that rely on manual pushing or using tools to strike the clamp, linear force is converted into torque, achieving labor-saving and improving the hydraulic vibratory hammer's adjustment efficiency. 2. During control, move the limiting cylinder and use the limiting component to stop the limiting cylinder from moving. The return spring is compressed until the clamp is outside the limiting cylinder, and the clamp holds the fixed protrusion ring. During this process, the clamp deforms and moves until it touches the surface of the extension column. Release the limiting component, and the limiting cylinder moves in the opposite direction under the force of the return spring and enters the clamp until the limiting cylinder covers the clamp again. At this time, the handwheel can be turned. The clamp cannot move due to the influence of the limiting cylinder, and the extension column is pressed by the torsional force, causing the rotating column to rotate, thereby achieving the effect of driving the adjustment gear to rotate. 3. When securing the other side of the mounting block, flip and move the hook plate so that it hooks into the groove. Then, rotate the securing bolt to move the push block. Through the sliding cooperation of the limiting rail and the pressure rod, the pressure rod descends until it presses against the bottom of the first waist-shaped groove, thereby limiting the movement of the hook plate and pressing the mounting block against the bottom wall of the securing groove, thus achieving the effect of securing the other side of the mounting.

[0041] When installing mounting block 3, insert the stabilizing flange into the stabilizing groove, and then insert the pressure block 412 into the pressure groove and the fixing frame 411 until the bottom end of the pressure block 412 is in contact with the inclined surface 4111. At this time, the top end of the pressure block 412 is flush with the top wall of the clamp 2. Rotate the locking bolt 413 to restrict the movement of the pressure block 412, thereby stabilizing one side of the mounting block 3. Then flip the hook plate 421 so that the hook plate 421 hooks the groove 31. Rotate the stabilizing bolt 425 to move the push block 423, which drives the pressure rod 422 to move. The pressure rod 422 touches the end wall of the second waist-shaped groove 32 and descends until it presses the bottom end of the first waist-shaped groove 4211 to restrict the movement of the hook plate 421, thereby stabilizing the other side of the mounting block 3 and completing the installation of mounting block 3.

[0042] Reference Figure 2 , Figure 8 and Figure 9 An adjustment assembly 5 is provided on the mounting block 3. The adjustment assembly 5 includes an adjustment gear 51, an adjustment rack 52, and a rotating shaft 53. The rotating shaft 53 is rotatably connected to the mounting block 3, and the adjustment gear 51 is fixedly connected to the end of the rotating shaft 53. The adjustment rack 52 is fixedly connected to the fixed track and is parallel to the length direction of the sliding track 11. The adjustment rack 52 meshes with the adjustment gear 51.

[0043] Reference Figure 8 and Figure 9 The clamp 2 is equipped with a control component 6, which includes a handwheel 61, clamps 62, a limiting cylinder 63, and a return spring 64. A rectangular column 531 is fixedly connected to one end of the rotating shaft 53, and a fixing protrusion 532 is fixedly connected to the end of the rectangular column 531. An extension column 611 is fixedly connected to the handwheel 61, and several clamps 62 are provided. In this embodiment, four clamps are used as an example, and all four clamps 62 are fixedly connected to the end of the extension column 611.

[0044] Reference Figure 8 and Figure 9 A limiting block 631 is fixedly connected to the limiting cylinder 63. A limiting groove is formed on the surface of the extension column 611. The limiting cylinder 63 is sleeved on the extension column 611, and the limiting block 631 is slidably fitted within the limiting groove. A fixing ring 612 is fixedly connected to the extension column 611. A return spring 64 is sleeved on the extension column 611 and located between the limiting cylinder 63 and the fixing ring 612. A limiting member 613, which is a rotating sleeve, is provided on the extension column 611 and is sleeved on the fixing ring 612. A threaded section is provided on the inner ring wall of the limiting member 613. In the initial state, the clamp 62 is located inside the limiting cylinder 63.

[0045] When adjusting the position of clamp 2, move the limiting cylinder 63 and rotate the limiting member 613 so that the limiting cylinder 63 is threaded onto the limiting member 613 until the clamp 62 is outside the limiting cylinder 63. Then, insert the clamp 62 into clamp 2.

Rotate the limiting member 613 in the opposite direction. The limiting cylinder 63 moves in the opposite direction under the force of the return spring 64 and covers the clamp 62. Rotate the handwheel 61, which drives the rectangular column 531 to rotate through the clamp 62, causing the rotating shaft 53 to rotate. The adjusting gear 51 rotates, and through the meshing of the adjusting gear 51 and the adjusting rack 52, the clamp 2 is moved to the designated position, thus achieving the effect of adjusting the position of clamp 2. During operation, the handwheel 61 and clamp 2 are in a separated state.

[0046] The implementation principle of a resonance-free hydraulic vibratory hammer with convenient clamping and debugging according to an embodiment of this application is as follows: During operation, the clamp 2 is set to a specified position according to the diameter of the foundation pile. Then, the limiting cylinder 63 is moved and the limiting member 613 is rotated, causing the limiting cylinder 63 to move until the clamp 62 disengages from the limiting cylinder 63. Then, the clamp 62 is sleeved on the fixed protrusion ring 532. During this process, the clamp 62 abuts against the fixed protrusion ring 532 and deforms until the clamp 62 passes through the fixed protrusion ring 532 and abuts against the surface of the rectangular column 531. The limiting member 613 is rotated in the opposite direction, and the limiting cylinder 63 moves in the opposite direction under the force of the return spring 64 until the limiting cylinder 63 covers the clamp 62. 2. At this time, turn the handwheel 61, the rotating shaft 53 rotates, driving the adjusting gear 51 to rotate until the clamp 2 moves to the designated scale line 111 position. Move the vibration box 1 and turn the handwheel 61 to fine adjust the position of the clamp 2 so that the top side wall of the foundation pile smoothly enters the two clamping grooves 22. Start the drive component 25, the clamping part 24 moves until it clamps the top side wall of the foundation pile. Start the hydraulic component 21, the output shaft of the hydraulic component 21 presses against the bottom wall of the sliding rail 11 to restrict the movement of the clamp 2. Use the lifting tool to lift the hydraulic vibratory hammer, lift the foundation pile, and insert the foundation pile into the foundation hole. Start the internal drive component of the hydraulic vibratory hammer to start the pile driving operation.

[0047] By rotating the rotating shaft 53, the clamp 2 is driven to move in conjunction with the adjusting gear 51 and the adjusting rack 52. Compared with the existing technology of manually pushing or using tools to hit the clamp 2, the linear force is transformed into torque force, which saves effort and improves the debugging efficiency of the hydraulic vibratory hammer.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
