Description

Technical Field

[0001] This utility model relates to the field of pile driver technology, specifically a hydraulic hammer pile driver. Background Technology

[0002] A hydraulic hammer pile driver is a type of piling machinery used to drive piles into the ground. There are many types of hydraulic hammer pile drivers, but the two most common types in construction engineering are hydraulic walking diesel hammer pile drivers and high-frequency hydraulic hammer vibratory pile drivers. High-frequency hydraulic hammer vibratory pile drivers use hydraulic components to fix the pile to a clamping assembly, and control the pile's descent via a hydraulic system mounted on the pile driver. The pile is then driven into the ground through vibration. However, in current technology, the shape of the bottom clamping assembly is generally fixed, limiting its ability to hold devices of a specified size. Furthermore, when the pile driver controls the clamping assembly to descend, the forearm on the pile driver will sway laterally. Since the pile is fixed to the ground, this causes the clamping assembly to exert lateral pressure on the top of the pile, potentially leading to bending or even breakage of the pile in the ground, thus affecting the quality of the piling process. Utility Model Content

[0003] The purpose of this utility model is to provide a hydraulic hammer pile driver to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic hammer pile driver, including a fixed frame, which is fixedly connected to the forearm of the pile driver. A rotating frame is rotatably installed at the bottom of the fixed frame. A vibration component is installed inside the rotating frame. A fixed plate is fixedly installed below the vibration component by bolts. An installation plate is slidably installed below the fixed plate. A fixed cylinder is fixedly installed at the bottom of the installation plate. The pile body can pass through the middle of the fixed cylinder. Hydraulic rods are fixedly installed in a ring array around the fixed cylinder with the central axis of the fixed cylinder as the axis. A clamping block is fixedly installed at the moving end of the hydraulic rod. The pile body is clamped between the four clamping blocks.

[0005] As a further preferred embodiment of this technical solution, the bottom of the fixing plate is symmetrically fixedly installed with limit rods, and the mounting plate is slidably installed between the two limit rods.

[0006] As a further preferred embodiment of this technical solution, reset springs are symmetrically sleeved on the outer sides of both ends of the limiting rod. One end of the reset spring is fixedly connected to one side of the mounting plate, and the other end of the reset spring is fixedly connected to the fixing plate.

[0007] As a further preferred embodiment of this technical solution, the inner wall of the fixed cylinder is provided with storage holes arranged in a ring array around the central axis of the fixed cylinder, and the clamping block can be stored inside the storage holes.

[0009] As a further preferred embodiment of this technical solution, the bottom inner wall of the fixed cylinder is provided with mounting grooves arranged in a ring array around the central axis of the fixed cylinder. A rotating shaft is rotatably mounted on the bottom end of the fixed cylinder corresponding to the mounting groove. A mounting rod is fixedly mounted on the middle of the rotating shaft.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4 As shown, in this embodiment, a hydraulic hammer pile driver includes a fixed frame 1, which is fixedly connected to the forearm of the pile driver by bolts. A rotating frame 2 is rotatably mounted on the bottom of the fixed frame 1 via a pivot pin. A vibration assembly 3 is installed inside the rotating frame 2. A fixed plate 4 is fixedly mounted below the vibration assembly 3 by bolts. An mounting plate 5 is slidably mounted below the fixed plate 4. A fixed cylinder 6 is fixedly mounted at the bottom of the mounting plate 5. The pile body can pass through the middle of the fixed cylinder 6. Hydraulic rods 7 are fixedly mounted in a circular array around the central axis of the fixed cylinder 6. The moving end of the hydraulic rod 7 is fixedly equipped with clamping blocks 8. The pile body is clamped between the four clamping blocks 8. The fixing cylinder 6 passes through the end of the pile body. The hydraulic rod 7 drives the four clamping blocks 8 to clamp and fix the pile body. It can squeeze and fix pile bodies of different sizes, thus improving the application range of this device. The pile body is inserted into the stratum by the hydraulic system of the pile driver and the movement of the vibration component 3. When installing the pile body, the mounting plate 5, which is indirectly installed with the pile body, slides under the fixing plate 4. This can maintain the relative fixation between the pile body and the stratum, and prevent the fixing plate 4, which is indirectly connected to the pile driver, from moving left and right and affecting the position of the pile body.

[0021] like Figures 1 to 4 As shown, the bottom of the fixing plate 4 is symmetrically fixed with limit rods 9 by bolts, and the mounting plate 5 is slidably installed between the two limit rods 9.

[0022] The movement of the mounting plate 5 can be connected and limited by the limiting rod 9, which can control the relative fixation between the pile body and the ground.

[0023] like Figures 1 to 4 As shown, reset springs 10 are symmetrically sleeved on the outer sides of both ends of the limiting rod 9. One end of the reset spring 10 is fixedly connected to one side of the mounting plate 5, and the other end of the reset spring 10 is fixedly connected to the fixing plate 4.

[0024] During the piling process, the reset spring 10 can push the offset mounting plate 5 and the fixed plate 4, which can be easily adjusted to adjust the position between the mounting plate 5 and the fixed plate 4.

[0025] like Figures 1 to 4 As shown, the inner wall of the fixed cylinder 6 is provided with storage holes 11 arranged in a ring array with the central axis of the fixed cylinder 6 as the axis, and the clamping block 8 can be stored inside the storage holes 11.

[0026] The clamping block 8 can be stored inside the storage hole 11 to prevent interference between the pile body and the clamping block 8 when the pile body is installed inside the fixing cylinder 6.

[0027] like Figures 1 to 4 As shown, the height of the clamping block 8 is half the height of the fixed cylinder 6.

[0028] This can maximize the stability of the compression between the clamping block 8 and the pile body.

[0029] like Figures 1 to 4 As shown, the bottom inner wall of the fixed cylinder 6 is provided with mounting grooves 12 arranged in a ring array around the central axis of the fixed cylinder 6. The bottom end of the fixed cylinder 6 corresponding to the mounting groove 12 is rotatably mounted with a rotating shaft 13 via a shaft pin. The middle part of the rotating shaft 13 is fixedly mounted with a mounting rod 14. The middle part of the end of the mounting rod 14 away from the rotating shaft 13 is rotatably mounted with a roller 15 via a shaft pin. Torsion springs 16 are symmetrically sleeved on the outer sides of both ends of the mounting groove 12. One end of the torsion spring 16 is fixedly connected to one side of the mounting rod 14, and the other end of the torsion spring 16 is fixedly connected to the fixed cylinder 6.

[0030] The rotation of the shaft 13 by the torsion spring 16 controls the mounting rod 14, which is mounted on the roller 15, to be in a horizontal position. When the fixing cylinder 6 passes through the end of the pile body, the pile body will press against the four rollers 15, positioning the control device between the four rollers 15 and centering the pile body in the middle of the fixing cylinder 6.

[0031] like Figures 1 to 4 As shown, a rubber pad 17 is fixedly installed on the inner wall of the top end of the fixed cylinder 6.

[0032] This can prevent the pile from excessively squeezing the inner wall of the top of the fixing cylinder 6, thus preventing damage to the inner wall of the top of the fixing cylinder 6.

[0033] This utility model provides a hydraulic hammer pile driver, the specific working principle of which is as follows:

[0034] When the device is in use, the fixed frame 1 is fixedly connected to the forearm of the pile driver. The device is moved by the large and small arms of the pile driver. The rotation of the rotating shaft 13 by the torsion spring 16 can control the installation rod 14, which is installed with the roller 15, to be set horizontally. When the fixed cylinder 6 passes through the end of the pile, the pile will squeeze the four rollers 15. The control device is positioned between the four rollers 15, and the pile is centered in the middle of the fixed cylinder 6. The hydraulic rod 7 drives the four clamping blocks 8 to clamp and fix the pile. Then, the fixed frame 1 is raised by the pile driver to set the pile vertically. The pile is inserted into the stratum by the hydraulic system of the pile driver and the movement of the vibration component 3. When the pile is installed, the installation plate 5, which is indirectly installed with the pile, will slide between the two limit rods 9 to keep the pile position relatively fixed with respect to the stratum and prevent the fixed plate 4, which is indirectly connected to the pile driver, from moving left and right and affecting the position of the pile.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
