Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a high-frequency vibration pipe pulling machine. Background Technology

[0002] In the construction of buildings or bridges, it is often necessary to install piles for support. Currently, piles are mostly installed by pouring concrete inside a casing, which solidifies to form a pile. After the concrete has initially set inside the casing, the casing often needs to be pulled out, which is usually done using a pipe-pulling machine.

[0003] Existing pipe-pulling machines can be connected to the casing and then pulled out the casing through hydraulic components. However, in actual pipe-pulling, it has been found that because the concrete will stick to the casing when it hardens, it is very difficult and time-consuming for common pipe-pulling machines to pull out the casing. Moreover, after pulling it out, a lot of concrete is easily brought out, resulting in a shortage of material in the formed pile and affecting the reliability of the formed pile.

[0004] In addition, common tube-pulling machines have difficulty ensuring the reliability of the connection with the sleeve, which can easily lead to situations where the tube-pulling machine cannot apply sufficient force to the sleeve, affecting the tube-pulling efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-frequency vibration tube pulling machine that can solve one or more of the above-mentioned problems.

[0006] According to one aspect of this utility model, a high-frequency vibration tube pulling machine is provided, comprising a vibrator, a clamping mechanism, a tube pulling mechanism, and a vibration damping mechanism. The vibrator can be used to connect with the sleeve, and the clamping mechanism and the sleeve pulling mechanism are provided with through holes for the sleeve to pass through. The clamping mechanism includes a first hydraulic cylinder, a guide plate, a movable plate, a clamping block, and a linkage mechanism. The first hydraulic cylinder is connected to the guide plate and the movable plate. The clamping block and the movable plate are connected by the linkage mechanism. The clamping block has a clamping part on one side and a first inclined surface on the other side. The guide plate has a second inclined surface. The first hydraulic cylinder can drive the moving plate to move, so that the first inclined surface slides along the second inclined surface, allowing the clamping block to move closer to or away from the through hole. The vibration damping mechanism includes a first spring, the guide plate is provided with a first protrusion, and the tube pulling mechanism is provided with a second protrusion. The two ends of the first spring are respectively sleeved on the first protrusion and the second protrusion. One end of the first spring abuts against the guide plate, and the other end abuts against the tube pulling mechanism.

[0007] The beneficial effects of this high-frequency vibration pipe pulling machine are as follows: The clamping mechanism in this invention, with its first and second inclined surfaces, effectively ensures the accuracy of the clamping block's movement. Through the operation of the first hydraulic cylinder, the clamping block reliably moves and effectively clamps the sleeve in the through hole, allowing the invention to apply force to the sleeve via the clamping block, thus ensuring effective pipe pulling. Furthermore, this invention includes a vibrator that applies high-frequency vibration to the sleeve during pulling, reducing the adhesion between the sleeve and the concrete inside, effectively reducing the difficulty of pulling out the sleeve relative to the concrete, improving pulling efficiency, and reducing the probability of damage to the concrete during pulling. Additionally, a vibration damping mechanism is provided to effectively dampen the vibration transmitted to the pipe pulling mechanism, reducing damage to the mechanism and improving its operational reliability.

[0008] In some embodiments, the tube-pulling mechanism includes a second hydraulic cylinder, a base plate, and a lifting plate. The second hydraulic cylinder is mounted on the lifting plate and connected to the base plate. The second hydraulic cylinder can drive the lifting plate to move up and down relative to the base plate to achieve the tube-pulling action.

[0009] In some embodiments, the first hydraulic cylinder includes a first cylinder body and a first piston rod, one end of the first piston rod being disposed within the first cylinder body. The first cylinder body is provided with a first hinge block, and the lifting plate is provided with a groove. A second hinge block is provided on the groove, and the first and second hinge blocks are hinged together. The first hydraulic cylinder can swing relative to the base plate to a certain extent, thereby reducing the probability of damage due to vibration caused by insufficient connection freedom. Furthermore, the groove limits the swing range of the first hydraulic cylinder to prevent excessive movement.

[0010] In some embodiments, the first piston rod is connected to a third hinge block, and the movable plate is connected to a fourth hinge block, with the third and fourth hinge blocks hinged together. This allows the first piston rod and the movable plate to oscillate to a certain extent, reducing the probability of damage due to vibration caused by insufficient connection freedom.

[0011] In some embodiments, the guide plate is sleeved on the first cylinder body. The first cylinder body can be restricted by the guide plate, reducing its movement and deviation.

[0012] In some embodiments, the second cylinder includes a second cylinder body and a second piston rod. The second cylinder body is embedded within a lifting plate, one end of the second piston rod is embedded in the second cylinder body, and the other end of the second piston rod is provided with a ball head. The base plate is connected to a ball head seat, and the ball head is disposed on the ball head seat. The ball head and ball head seat allow the second piston rod to swing relative to the base plate to a certain extent, thereby reducing the probability of damage due to vibration caused by insufficient connection freedom.

[0013] In some embodiments, the linkage mechanism includes a first link, a second link, and a third link, wherein the first link is connected to a movable plate, the third link is connected to a clamping block, one end of the second link is hinged to the first link, and the other end of the second link is hinged to the third link.

[0014] In some embodiments, the vibration damping mechanism includes a bolt and a second spring. The bolt connects the guide plate and the tube-pulling mechanism, and the second spring is sleeved on the bolt. One end of the second spring abuts against the guide plate, and the other end abuts against the tube-pulling mechanism. The bolt enables an effective connection between the tube-pulling mechanism and the guide plate, and the second spring buffers the vibration transmitted from the guide plate to the tube-pulling mechanism, thereby reducing the vibration received by the tube-pulling mechanism.

[0015] According to one aspect of the present invention, a tube-pulling method using a high-frequency vibration tube-pulling machine is provided, comprising the following steps: The high-frequency vibratory pipe pulling machine is fitted onto a sleeve with internal concrete filling, allowing the sleeve to pass through a through hole, and the vibrator is connected to the outside of the sleeve. The first hydraulic cylinder is activated, causing the moving plate to move downwards. As the moving plate moves, the clamping block moves downwards accordingly. Simultaneously, the first inclined surface on the clamping block slides down along the second inclined surface. During the sliding process of the clamping block, the linkage mechanism matches the movement of the clamping block, allowing the clamping block to approach the through hole until the clamping part fully engages with the sleeve inside the through hole, thus achieving clamping of the sleeve. The vibrator is started, applying high-frequency vibration to the casing to reduce adhesion between the casing and the concrete. The tube-pulling mechanism is activated, which drives the sleeve held by the clamping block to rise, thereby pulling out the sleeve.

[0016] The beneficial effects of the tube pulling method of this high-frequency vibration tube pulling machine are as follows: the clamping mechanism clamps the sleeve in the above manner, which can ensure that the clamping block and the sleeve are in full contact so that the force can be effectively applied during subsequent pulling. In addition, by setting up a vibrator to apply high-frequency vibration, the adhesion between the sleeve and the concrete can be effectively reduced, thereby reducing the difficulty of pulling out the sleeve, improving the efficiency of pulling out the sleeve, and reducing damage to the concrete.

[0017] In some embodiments, the driving of the clamping block by the tube-pulling mechanism includes the following steps: When the second hydraulic cylinder is activated, it drives the lifting plate to rise, which in turn raises the clamping mechanism connected to the lifting plate, i.e., the clamping block rises, thus driving the clamping block.

[0027] The tube-pulling mechanism 3 includes a second hydraulic cylinder 31, a base plate 32, and a lifting plate 33. There can be multiple second hydraulic cylinders 31; in this embodiment, four are preferred. The four second hydraulic cylinders 31 are respectively mounted on the lifting plate 33, and are located at the four corners of the second hydraulic cylinder 31. All the second hydraulic cylinders 31 are connected to the base plate 32.

[0028] Preferably, in each second cylinder 31, the second cylinder 31 includes a second cylinder body 311 and a second piston rod 312. The second cylinder body 311 is fixedly embedded in the lifting plate 33. One end of the second piston rod 312 is embedded in the second cylinder body 311 through a piston, so that the second piston rod 312 can move relative to the second cylinder body 311. The other end of the second piston rod 312 is provided with a ball head 313. A ball head seat 321 is connected on the base plate 32. The number of ball head seats 321 is equivalent to the number of second cylinders 31. The ball heads 313 on the four second cylinders 31 are rotatably embedded in the four ball head seats 321.

[0029] The clamping mechanism 2 includes a first hydraulic cylinder 21, a guide plate 22, a moving plate 23, a clamping block 24, and a linkage mechanism 25. There can be multiple first hydraulic cylinders 21. In this embodiment, four first hydraulic cylinders 21 are preferably connected to the guide plate 22, and each of the four first hydraulic cylinders 21 is connected to the moving plate 23. The four first hydraulic cylinders 21 are located at the four corners of the moving plate 23.

[0030] Preferably, each first cylinder 21 includes a first cylinder body 211 and a first piston rod 212. One end of the first piston rod 212 is slidably disposed within the first cylinder body 211 via a piston. A first hinge block 213 is provided at the bottom of the first cylinder body 211. A groove 331 is provided on the lifting plate 33, and the number of grooves 331 is equivalent to the number of first cylinders 21. A second hinge block 332 is provided on each groove 331. The first hinge blocks 213 on the four first cylinders 21 and the second hinge blocks 332 on the four grooves 331 are respectively hinged together by pins. A guide plate 22 is sleeved on all the first cylinder bodies 211.

[0031] In each first hydraulic cylinder 21, a third hinge block 214 is integrally formed and fixedly connected to the first piston rod 212. The movable plate 3 is connected to a plurality of fourth hinge blocks 231, the number of fourth hinge blocks 231 being equivalent to the number of first hydraulic cylinders 21, and the four third hinge blocks 214 are respectively hinged to the four fourth hinge blocks 231 by pins.

[0032] The clamping block 24 and the movable plate 23 are connected by a linkage mechanism 25. Preferably, there can be multiple linkage mechanisms 25. In this embodiment, there are eight linkage mechanisms 25, which are evenly distributed around the center line of the through hole 20. Each linkage mechanism 25 includes a first link 251, a second link 252, and a third link 253. The first link 251 is integrally connected to the movable plate 23, and the third link 252 is integrally connected to the clamping block 24. One end of the second link 252 is hinged to the first link 251 by a pin, and the other end of the second link 252 is hinged to the third link 253 by a pin. Thus, the movement of the movable plate 23 can drive the clamping block 24 to move through the linkage mechanism 25.

[0033] The through hole 20 passes through the clamping block 24. The clamping block 24 has a clamping part 241 on its inner side, that is, the clamping part 241 is located around the through hole 20. The clamping block 24 has a first inclined surface 242 on its outer side. The through hole 20 also passes through the guide plate 22. The guide plate 22 has a second inclined surface 221 on its inner side. The first inclined surface 242 is attached to the second inclined surface 221, so the first inclined surface 242 can slide along the second inclined surface 221. As the first inclined surface 242 slides on the second inclined surface 221, the clamping block 24 can move closer to or away from the through hole 20. In this embodiment, when the first inclined surface 242 slides down along the second inclined surface 221, the clamping block 24 can move closer to the through hole 20. When the first inclined surface 242 slides up along the second inclined surface 221, the clamping block 24 can move closer to the through hole 20.

[0034] The guide plate 22 and the lifting plate 33 are connected by a vibration damping mechanism 4. Preferably, the vibration damping mechanism 4 includes a first spring 41, a first protrusion 222 is provided on the guide plate 22, and a second protrusion 333 is provided on the lifting plate 33 of the tube pulling mechanism 3. The two ends of the first spring 41 are respectively sleeved on the first protrusion 222 and the second protrusion 333, and one end of the first spring 41 abuts against the guide plate 22, and the other end of the first spring 41 abuts against the tube pulling mechanism 3.

[0035] The vibration damping mechanism 4 may also include a bolt 42 and a second spring 43. The bolt 42 connects the guide plate 22 and the lifting plate 33 of the tube pulling mechanism 3, and the second spring 43 is sleeved on the bolt 42. One end of the second spring 43 abuts against the guide plate 22, and the other end of the second spring 43 abuts against the lifting plate 33 of the tube pulling mechanism 3.

[0036] The tube-pulling method of this high-frequency vibration tube-pulling machine includes the following steps: The high-frequency vibration tube pulling machine can be fitted onto the sleeve 10, which is filled with concrete, so that the sleeve 10 can pass through the through hole 20, and the vibrator 1 can be connected to the outer periphery of the sleeve 10.

[0037] When the concrete inside the sleeve 10 has initially solidified and it is necessary to pull out the sleeve 10, the first hydraulic cylinder 21 is activated. The first hydraulic cylinder 21 can drive the moving plate 23 to move down. As the moving plate 23 moves, the clamping block 24 can move down accordingly. At the same time, the first inclined surface 242 on the clamping block 24 can slide down along the second inclined surface 221. During the sliding of the clamping block 24, the second connecting rod 252 on the linkage mechanism 25 can move accordingly to match the movement of the clamping block 24. The clamping block 24 can approach the through hole 20 until the clamping part 241 on the clamping block 24 is fully in contact with the sleeve 10 inside the through hole 20, thereby achieving effective clamping of the sleeve 10.

[0038] Start vibrator 1. Vibrator 1 applies high-frequency vibration to sleeve 10 to reduce the adhesion between sleeve 10 and the initially solidified concrete inside it.

[0039] When the second hydraulic cylinder 31 is activated, the second hydraulic cylinder 31 can drive the lifting plate 33 to rise, and the clamping mechanism 2 connected to the lifting plate 33 will also rise accordingly, that is, the clamping block 24 rises, that is, the tube pulling mechanism 3 can drive the sleeve held by the clamping block 24 to rise, thereby realizing the pulling out of the sleeve 10.

[0040] In addition, during the tube removal process, the vibration transmitted from the sleeve 10 to the clamping mechanism 2 can be buffered by the first spring 41 and the second spring 43 between them when the vibration is transmitted from the clamping mechanism 2 to the lifting plate 33 of the tube removal mechanism 3. This effectively reduces the vibration transmitted to the lifting plate 33, reduces the damage to the lifting plate 33, and improves the working reliability of the lifting plate 33.

[0041] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
