Pile clamping device and pile clamping method of hydraulic static pile driver

Abstract

This invention relates to the field of pile driving technology and discloses a pile clamping device and method for a hydraulic static pile driver. The device includes a triggering assembly, which comprises a ring, a rotating rod rotatably connected to the inner wall of the ring, and a roller rotatably connected to the inner wall of the rotating rod. As the pile moves downwards, the roller rotates. During rotation, the roller drives a rotating shaft via a belt, which in turn drives a bevel gear via a belt. The bevel gear, in turn, drives a gear ring via a gear rod, which in turn drives a protruding ring via a rotating ring. The protruding ring then drives a brush plate, which effectively cleans the sand and gravel from the outer surface of the pile. This design, by having the brush plate rotate against the outer surface of the pile during its descent, effectively cleans the outer surface and prevents sand and gravel from affecting the pile clamping assembly.

Description

Technical Field

[0001] This invention relates to the field of pile driving technology, specifically to a pile clamping device and method for a hydraulic static pile driver. Background Technology

[0002] The pile clamping device of a hydraulic static pile driver is typically designed to fix and hold the pile material, ensuring its stability and verticality as it is driven into the foundation. This device is crucial on the construction site because it directly affects the pile's positioning and safety.

[0003] Since the piles are generally placed horizontally on the ground at the construction site before being driven into the foundation, sand and gravel on the surface of the construction site can easily embed into the surface of the piles. When the piles are driven into the foundation, the sand and gravel on their surface may affect the pile clamping device, making it impossible to ensure that the piles remain stable and vertical when driven into the foundation. To address the above problems, the following solutions are proposed. Summary of the Invention

By setting the gear rod, the gear ring can be driven to rotate.

[0010] Preferably, the top of the gear ring is fixedly connected to the bottom of the rotating ring, a sealing ring is rotatably connected to the outer surface of the protruding ring, the inner wall of the sealing ring is fixedly connected to the outer surface of the circular ring, an air guide pipe is fixedly connected to the outer surface of the sealing ring, the end of the air guide pipe away from the sealing ring is fixedly connected to the top of the circular ring, a sliding pressure plate is slidably connected to the inner wall of the circular ring, a connecting rod is slidably connected to the inner wall of the sliding pressure plate, and the inner wall of the connecting rod is rotatably connected to the outer surface of the roller. By setting the sealing ring, air can be introduced into the protruding ring during its rotation.

[0011] Preferably, there are two fixing plates, and each fixing plate is fixedly connected to a limit rod on one side close to the other. A sleeve plate is fixedly connected to the outer surface of the telescopic rod. The inner wall of the sleeve plate is slidably connected to the outer surface of the limit rod. The left side of the sleeve plate is fixedly connected to the right side of the second spring, and the right side of the left fixing plate is fixedly connected to the left side of the second spring. By setting the limit rod, the sleeve plate and the telescopic rod can be limited.

[0012] Preferably, an electric connecting rod is slidably connected to the inner wall of the fixed plate, and a second air guide pipe is fixedly connected to the right side of the fixed plate. The end of the second air guide pipe away from the fixed plate is fixedly connected to the outer surface of the sealing sleeve. A first clamping plate is fixedly connected to the output end of the telescopic rod. Gears are meshed on the front and back of the first clamping plate, and a second clamping plate is meshed on the outer surface of the gears. The outer surface of the second clamping plate is slidably connected to the inner wall of the bottom plate. By setting the first clamping plate and the second clamping plate, the pile material can be clamped and stabilized.

[0013] A pile clamping method for a hydraulic static pile driver's pile clamping device includes the following steps:

[0014] S1: When using this device, first install the device in the designated position, then introduce an appropriate amount of lubricating oil into the device through the oil inlet pipe connected to the top of the oil storage box and keep it there. When the pile material passes through the device, the lubricating oil in the oil storage box will be squeezed out to lubricate the device.

[0015] S2: During the rotation of the rotating rod, the air in the second ring will enter the protruding ring. The air will push the brush plate so that the brush surface of the brush plate can contact the surface of the pile. As the pile moves downward, the protruding ring will drive the brush plate to rotate and clean.

[0016] S3: When air is introduced into the sealing collar, it will also enter the second air guide tube and push the power-on rod to the left, thereby making the clamping surfaces of the first clamping plate and the second clamping plate come into contact with the pile material to clamp it.

[0017] The present invention has the following beneficial effects:

[0018] (1) As the pile moves downward, the roller will rotate. During the rotation, the roller will only drive the rotating shaft to rotate via belt one. When the rotating shaft rotates, it will drive the bevel gear to rotate via belt two. During the rotation, the bevel gear will drive the gear ring to rotate via the gear rod. The gear ring will drive the protruding ring to rotate via the rotating ring. The protruding ring will drive the brush plate to rotate, thereby fully cleaning the sand and gravel on the outer surface of the pile. This design allows the brush plate to rotate along the outer surface of the pile during the descent of the pile, thereby fully cleaning the outer surface of the pile and preventing the sand and gravel on the surface of the pile from affecting the pile clamping assembly, which would prevent it from ensuring that the pile remains stable and vertical when pressed into the foundation. Moreover, this design does not require a power source, which can save energy and reduce energy consumption.

[0019] (2) During the process of the pile material passing through the device, its surface will contact the surface of the roller, and the roller will drive the rotating rod to rotate to adapt to the radius of the pile material. During the rotation of the rotating rod, it will stretch the belt two upward through the rotating shaft. During the stretching process, the belt two will give a pulling force to the rotating sleeve and the sliding rod, so that the sliding rod slides inside the support frame and compresses the spring one. During the movement of the sliding rod, it will drive the sliding pressure plate one to compress the lubricating oil inside the oil storage box. The lubricating oil will be squeezed and discharged through the oil outlet pipe at its bottom to lubricate the gear at its bottom. This design allows the rotating rod to rotate without affecting the normal transmission of the belt two through the compression of the spring one by the sliding rod, and can lubricate the device through the squeezed lubricating oil, thereby reducing the energy loss of the rotating parts and improving the energy efficiency of the system.

[0020] (3) During the rotation of the rotating rod, the sliding pressure plate 2 will also move through the connecting rod. During the movement of the sliding pressure plate 2, the air in the ring 2 will be compressed to allow the air to enter the air guide pipe 1. The air guide pipe 1 will pass the air through the fixed collar into the protruding ring. The air entering the protruding ring will push the brush plate so that the brush surface of the brush plate can contact the surface of the pile material. This design can automatically adjust the length of the brush plate extension according to the radius of the pile material, so that the device can adapt to pile materials of different radii, thus improving the practicality and convenience of the device.

[0021] (4) When air is introduced into the sealing ring, it will also enter the second air guide pipe and push the power-on connecting rod to the left. When the power-on connecting rod contacts the inner wall of the fixed plate, a passage is formed between the telescopic rod and the power source, and the telescopic rod will be activated. After activation, the telescopic rod will push the clamping plate one to the right at a slower speed. During the movement of the clamping plate one to the right, the clamping plate two will be moved by the gear. When the bottom of the pile material passes through the bottom plate, the clamping plate one and the clamping plate two will move to the maximum radius where the device can clamp the pile material. As the telescopic rod continues to push the clamping plate one, the clamping surfaces of the clamping plate one and the clamping plate two will contact the surface of the pile material. Both clamping surfaces of clamping plates one and two are equipped with rotating wheels to prevent friction damage to the surface of the pile material during downward movement. After clamping plates one and two contact the pile material, the telescopic rod continues to push clamping plate one, which will receive a reaction force, causing the telescopic rod to move the sleeve plate to the left and compress spring two. The gradually increasing elastic force of spring two clamps and stabilizes the pile material. This design can automatically activate the telescopic rod to clamp and stabilize the pile material, so that the pile material remains stable and vertical during the pressing process and after installation. Furthermore, the rotating wheels and the flexible elastic force of spring two ensure that the device will not damage the outer surface of the pile material when it descends.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, please refer to Figure 1 - Figure 5 This invention relates to a pile clamping device for a hydraulic static pile driver, comprising a trigger assembly 1. The trigger assembly 1 includes a ring 101, a rotating rod 102 rotatably connected to the inner wall of the ring 101, and a roller 103 rotatably connected to the inner wall of the rotating rod 102. The device also includes:

[0036] Cleaning component 2 includes a rotating ring 201 disposed at the bottom of the circular ring 101, a protruding ring 202 fixedly connected to the inner wall of the rotating ring 201, and a brush plate 203 slidably connected to the inner wall of the protruding ring 202.

[0037] The pile clamping assembly 3 includes a base plate 301 disposed at the bottom of the ring 101, a fixing plate 303 fixedly connected to the top of the base plate 301, and a telescopic rod 302 slidably connected to the inner wall of the fixing plate 303.

[0038] The inner wall of roller 103 is in contact with belt 104, and the inner wall of rotating rod 102 is rotatably connected to rotating shaft 105. The outer surface of rotating shaft 105 is in contact with the inner wall of belt 104. Roller 103 and rotating shaft 105 are connected by belt 104. The outer surface of rotating shaft 105 is in contact with belt 2 106. The inner wall of belt 2 106 is in contact with rotating sleeve 107 and bevel gear 113 respectively. When a hoisting device presses the pile into the foundation, the pile is first passed through this device from the top of ring 101. During the process of the pile passing through this device, its surface will contact the surface of roller 103, and the rotating rod 102 will be rotated through roller 103 to adapt to the radius of the pile.

[0039] A sliding rod 108 is rotatably connected to the inner wall of the rotating sleeve 107. A support frame 109 is slidably connected to the outer surface of the sliding rod 108. A spring 110 is installed inside the support frame 109. The left side of the spring 110 is fixedly connected to the left side of the inner wall of the support frame 109, and the right side of the spring 110 is fixedly connected to the left side of the sliding rod 108. A sliding pressure plate 111 is slidably connected to the inner wall of the support frame 109. The outer surface of the sliding pressure plate 111 is fixedly connected to the inner wall of the sliding rod 108. An oil reservoir 112 is slidably connected to the outer surface of the sliding pressure plate 111. A ring 114 is fixedly connected to the bottom of the oil reservoir 112. The bottom of the support frame 109 is fixedly connected to the top of the ring 114. During the rotation of the rotating rod 102, it will pass through the rotating shaft 105. When belt 106 is stretched upwards, it applies a tension to rotating sleeve 107 and sliding rod 108, causing sliding rod 108 to slide inside support frame 109 and compress spring 110. As sliding rod 108 moves, it drives sliding pressure plate 111 to compress the lubricating oil inside oil reservoir 112. The compressed lubricating oil is discharged through oil outlet pipe at its bottom to lubricate the gears at its bottom. This design, through the compression of spring 110 by sliding rod 108, allows rotating rod 102 to rotate without affecting the normal transmission of belt 106, and the device can be lubricated by the compressed lubricating oil, thereby reducing energy loss of rotating parts and improving the energy efficiency of the system.

[0040] The outer surface of bevel gear 113 is rotatably connected to the inner wall of ring 2 114. The top of ring 2 114 is fixedly connected to the bottom of ring 1 101. A gear rod 115 is meshed with the bottom of bevel gear 113. The outer surface of gear rod 115 is rotatably connected to the inner wall of ring 3 116. A gear ring 117 is meshed with the right side of gear rod 115. The outer surface of gear ring 117 is rotatably connected to the inner wall of ring 3 116. As the pile moves downward, it will drive roller 103 to rotate. During the rotation of roller 103, it will drive rotating shaft 105 to rotate through belt 1 104. When rotating shaft 105 rotates, it will drive bevel gear 113 to rotate through belt 2 106. During the rotation of bevel gear 113, it will drive gear ring 117 to rotate through gear rod 115.

[0041] Example 2, please refer to Figure 6 - Figure 9 This invention relates to a pile clamping device for a hydraulic static pile driver. Based on Embodiment 1, the top of the gear ring 117 is fixedly connected to the bottom of the rotating ring 201. A sealing sleeve 204 is rotatably connected to the outer surface of the protruding ring 202. The inner wall of the sealing sleeve 204 is fixedly connected to the outer surface of the third ring 116. An air guide pipe 205 is fixedly connected to the outer surface of the sealing sleeve 204. The end of the air guide pipe 205 away from the sealing sleeve 204 is fixedly connected to the top of the second ring 114. A sliding pressure plate 206 is slidably connected to the inner wall of the second ring 114. A connecting rod 207 is slidably connected to the inner wall of the sliding pressure plate 206. The inner wall of the connecting rod 207 is rotatably connected to the outer surface of the roller 103. The gear ring 117 drives the protruding ring 202 to rotate via the rotating ring 201. The protruding ring 202 drives the brush plate 203 to rotate, thereby thoroughly cleaning the sand and gravel on the outer surface of the pile. This design allows the brush plate 203 to rotate during the pile's descent. 3. The rotating rod 102 rotates along the outer surface of the pile material, thereby thoroughly cleaning the outer surface of the pile material and preventing sand and gravel on the pile material surface from affecting the pile clamping assembly, which would prevent the pile material from maintaining a stable and vertical state when pressed into the foundation. This design does not require a power source, thus saving energy and reducing energy consumption. During the rotation of the rotating rod 102, it also drives the sliding pressure plate 206 to move through the connecting rod 207. During the movement of the sliding pressure plate 206, the air in the annular ring 114 is compressed to allow the air to be introduced into the air guide pipe 205. The air guide pipe 205 then introduces the air through the fixed collar 204 into the protruding ring 202. The air introduced into the protruding ring 202 pushes the brush plate 203 so that the brush surface of the brush plate 203 can contact the surface of the pile material. This design can automatically adjust the extension length of the brush plate 203 according to the radius of the pile material, so that the device can adapt to pile materials of different radii, improving the practicality and convenience of the device.

[0042] There are two fixing plates 303. Limiting rods 304 are fixedly connected to the two fixing plates 303 on their adjacent sides. A sleeve plate 305 is fixedly connected to the outer surface of the telescopic rod 302. The inner wall of the sleeve plate 305 is slidably connected to the outer surface of the limiting rod 304. The left side of the sleeve plate 305 is fixedly connected to the right side of the second spring 306. The right side of the left fixing plate 303 is fixedly connected to the left side of the second spring 306. When air enters the sealing ring 204, it will also enter the second air guide tube 309 and push the energized connecting rod 307 to the left. When the energized connecting rod 307 contacts the inner wall of the fixing plate 303, a passage is formed between the telescopic rod 302 and the power source, and the telescopic rod 302 will be activated.

[0043] A power-conducting rod 307 is slidably connected to the inner wall of the fixed plate 303. A second air guide pipe 309 is fixedly connected to the right side of the fixed plate 303. The end of the second air guide pipe 309 furthest from the fixed plate 303 is fixedly connected to the outer surface of the sealing collar 204. A clamping plate 310 is fixedly connected to the output end of the telescopic rod 302. Gears 311 are meshed with the front and back of the clamping plate 310, respectively. A second clamping plate 312 is meshed with the outer surface of the gears 311. The outer surface of the second clamping plate 312 is slidably connected to the inner wall of the base plate 301. Upon activation, the telescopic rod 302 will push the first clamping plate 310 to the right at a relatively slow speed. During this movement, the clamping plate 310 will drive the second clamping plate 312 to move via the gears 311. When the bottom of the pile material passes through the base plate 301, the first clamping plate 310 and the second clamping plate 312 will move to the maximum radius at which the device can clamp the pile material. The telescopic rod 302 continues to push the clamping plate 310, and the clamping surfaces of the clamping plate 310 and the clamping plate 312 will come into contact with the surface of the pile. Both the clamping surfaces of the clamping plate 310 and the clamping plate 312 are equipped with rotating wheels to prevent the surface of the pile from being damaged by friction during the downward movement. After the clamping plates 310 and 312 come into contact with the pile, the telescopic rod 302 continues to push the clamping plate 310 and will receive a reaction force, causing the telescopic rod 302 to drive the sleeve plate 305 to move to the left and compress the spring 306. The gradually increasing elastic force of the spring 306 clamps and stabilizes the pile. This design can automatically activate the telescopic rod 302 to clamp and stabilize the pile, so that the pile remains stable and vertical during the pressing process and after installation. Moreover, the rotating wheels and the flexible elastic force of the spring 306 prevent the device from damaging the outer surface of the pile when it descends.

[0044] The pile clamping method of this pile clamping device includes the following steps:

[0045] S1: When using this device, first install the device in the designated position, then input an appropriate amount of lubricating oil into the oil storage box 112 through the oil inlet pipe connected to the top of the oil storage box 112 and keep it there. When the pile material passes through the device, the lubricating oil in the oil storage box 112 will be squeezed out to lubricate the device.

[0046] S2: During the rotation of the rotating rod 102, the air in the second annulus 114 will be introduced into the protruding ring 202. The introduced air will push the brush plate 203 so that the brush surface of the brush plate 203 can contact the surface of the pile. As the pile moves downward, the protruding ring 202 will drive the brush plate 203 to rotate and clean.

[0047] S3: When air enters the sealing collar 204, it will also enter the air guide pipe 309 and push the power rod 307 to the left, thereby making the clamping surfaces of clamping plate 310 and clamping plate 312 contact the pile material to clamp it.

[0048] One specific application of this embodiment is:

[0049] When using this device, first install it in the designated position. Then, through the oil inlet pipe connected to the top of the oil storage box 112, inject an appropriate amount of lubricating oil into it and maintain it. When a hoisting device presses the pile into the foundation, first pass the pile through the top of the ring 101 through this device. During the process of the pile passing through this device, its surface will contact the surface of the roller 103, and the roller 103 will drive the rotating rod 102 to rotate to adapt to the radius of the pile. During the rotation of the rotating rod 102, it will stretch the belt 106 upward through the rotating shaft 105. During the stretching process, the belt 106 will provide support to the rotating sleeve 107. A tension force is applied to the sliding rod 108, causing it to slide inside the support frame 109 and compress the spring 110. During its movement, the sliding rod 108 drives the sliding pressure plate 111 to compress the lubricating oil inside the oil storage box 112. The compressed lubricating oil is discharged through the oil outlet pipe at its bottom to lubricate the gears at its bottom. This design, through the compression of the spring 110 by the sliding rod 108, allows the rotating rod 102 to rotate without affecting the normal transmission of the belt 106, and the device can be lubricated by the compressed lubricating oil, thereby reducing the energy loss of the rotating parts and improving the energy efficiency of the system.

[0050] During the rotation of the rotating rod 102, it also drives the sliding pressure plate 206 to move via the connecting rod 207. The sliding pressure plate 206 compresses the air in the annular ring 114 during its movement, allowing the air to be introduced into the air guide pipe 205. The air guide pipe 205 then passes the air through the fixed collar 204 into the protruding ring 202. The air entering the protruding ring 202 pushes the brush plate 203 so that its brush surface can contact the surface of the pile material. This design automatically adjusts the extension length of the brush plate 203 according to the radius of the pile material, allowing the device to adapt to pile materials of different radii, thus improving the practicality and convenience of the device. As the pile material moves downwards, it drives the roller 103 to rotate. During the rotation of the roller 103, it is driven to rotate via the belt 104. Shaft 105 rotates, and when shaft 105 rotates, it drives bevel gear 113 to rotate via belt 106. During the rotation of bevel gear 113, it drives gear ring 117 to rotate via gear rod 115. Gear ring 117 drives protruding ring 202 to rotate via rotating ring 201. Protruding ring 202 drives brush plate 203 to rotate, thereby thoroughly cleaning the sand and gravel on the outer surface of the pile. This design allows brush plate 203 to rotate along the outer surface of the pile during the descent of the pile, thereby thoroughly cleaning the outer surface of the pile and preventing sand and gravel on the pile surface from affecting the pile clamping assembly, which would prevent the pile from maintaining a stable and vertical state when pressed into the foundation. Moreover, this design does not require a power source, which can save energy and reduce energy consumption.

[0051] During the above process, when air enters the sealing collar 204, it also enters the second air guide pipe 309 and pushes the energizing rod 307 to the left. When the energizing rod 307 contacts the inner wall of the fixing plate 303, a path is formed between the telescopic rod 302 and the power source, and the telescopic rod 302 is activated. After activation, the telescopic rod 302 will push the first clamping plate 310 to the right at a relatively slow speed. During the movement of the first clamping plate 310 to the right, the second clamping plate 312 will be moved through the gear 311. When the bottom of the pile passes through the base plate 301, the first clamping plate 310 and the second clamping plate 312 will move to the maximum radius at which the device can clamp the pile. As the telescopic rod 302 continues to push the first clamping plate 310, the clamping surfaces of the first clamping plate 310 and the second clamping plate 312 will... Both clamping plates 310 and 312 are equipped with rotating wheels on their clamping surfaces to prevent friction damage to the pile surface during downward movement. After clamping plates 310 and 312 contact the pile, the telescopic rod 302 continues to push clamping plate 310, which will receive a reaction force. This causes the telescopic rod 302 to move sleeve 305 to the left and compress spring 306. The gradually increasing elastic force of spring 306 clamps and stabilizes the pile. This design can automatically activate the telescopic rod 302 to clamp and stabilize the pile, so that the pile remains stable and vertical during the pressing process and after installation. Furthermore, the rotating wheels and the flexible elastic force of spring 306 prevent damage to the outer surface of the pile when it descends.
