Description

Technical Field

[0001] This utility model relates to the field of engineering construction, specifically to a pile clamping and pulling machine for construction methods. Background Technology

[0002] Construction of underground piles using the method involves drilling to a certain depth on-site with a multi-axis drilling and mixing machine. A cement-based reinforcing agent is sprayed at the drill bit and repeatedly mixed with the foundation soil. Overlapping joints are used between construction units. Then, before the cement-soil mixture hardens, steel plates are inserted as stress reinforcement until the cement hardens, forming a seamless underground wall with a certain strength and rigidity. Construction piles are widely used in deep foundation pit excavation, especially suitable for soft soil foundations or where vertical excavation is required to retain the foundation pit where there are surrounding buildings or pipelines that cannot be displaced. In addition, construction piles can also be used in foundation reinforcement, slope protection, and other engineering fields.

[0003] With the acceleration of urban modernization in my country, the demolition of structural piles in old buildings has become a complex and crucial process. Traditionally, pile extraction is done manually, a time-consuming and labor-intensive method. With rising labor costs, manual extraction further increases demolition costs. Existing technologies also employ clamping equipment for holding the piles, followed by lifting with cranes. However, because the piles often extend deep into the ground and may be affected by tightly packed soil or groundwater levels, the extraction process faces significant resistance, leading to the problem of structural steel detachment.

[0004] Therefore, it is very necessary to provide a pile clamping and pulling machine to solve the above-mentioned technical problems. Utility Model Content

[0032] like Figures 1 to 8As shown, a pile clamping and pulling machine includes a mounting base 1, a first support member 2, a second support member 3, a clamping member 4, and a base lifting member 5. The first support member 2 includes a first support plate 21, which is rotatably connected to the mounting base 1. The second support member 3 includes a second support plate 31, at least two of which are rotatably connected to the mounting base 1 and located on opposite sides of the first support plate 21. The clamping member 4 includes a top plate 41 and a clamping drive member 42. The top plate 41 is provided in two sets, with at least two top plates 41 in each set. One of the two top plates 41 is connected to the first support member 1. One plate 21 is correspondingly arranged, and another is correspondingly arranged with the second support plate 31. The top plate 41 is rotatably connected to the mounting base 1. The clamping drive member 42 is connected to the mounting base 1, and the driving end of the clamping drive member 42 is connected to the top plate 41. The clamping drive member 42 can drive the top plate 41 to rotate to approach or move away from the first support plate 21 and the second support plate 31, thereby realizing the clamping of the construction pile. At least two seat lifting members 5 are provided. The two seat lifting members 5 are connected to both sides of the mounting base 1. The seat lifting members 5 can lift the mounting base 1 when extended and lower the mounting base 1 when retracted.

[0033] In this embodiment, a clamping drive component 42 is connected to the mounting base 1. When it is necessary to clamp the construction pile, the clamping drive component 42 extends, driving the top plate 41 to rotate and approach the first support plate 21 and the second support plate 31 to clamp the construction pile. At this time, the base lifting component 5 lifts the mounting base 1, clamping the construction pile a certain distance from the ground. Immediately afterwards, the clamping drive component 42 retracts, driving the top plate 41 to rotate, moving the top plate 41 away from the first support plate 21 and the second support plate 31 to release the construction pile. At this time, the base lifting component 5 lowers the mounting base 1. This process is repeated until the construction pile is pulled out. This application can stably clamp the construction pile by using two sets of top plates 41 respectively with the first support plate 21 and the second support plate 31. This effectively solves the problem of easy detachment when using clamping equipment to clamp construction steel in the prior art.

[0034] In some embodiments, the first support member 2 includes a first frame 22 and a first connecting rod 23 connected to the first frame 22. The first connecting rod 23 is rotatably connected to the first support plate 21, and the first frame 22 is provided with an inclined surface 24, and the first support plate 21 abuts against the inclined surface 24.

[0035] In this embodiment, the first connecting rod 23 is connected to the first frame 22 and rotatably connected to the first support plate 21, so that the first support plate 21 can better cooperate with the top plate 41, thereby providing a more stable clamping of the construction pile.

[0036] In some embodiments, the first support plate 21 is provided with a first sliding groove 25, and the first support plate 21 is slidably connected to the first connecting rod 23 through the first sliding groove 25. The first sliding groove 25 is configured such that: when the mounting base 1 is lowered, the first support plate 21 can slide towards the upper side of the first sliding groove 25 to release the construction pile; when the mounting base 1 is raised, the first support plate 21 and the top plate 41 clamp the construction pile, and the first support plate 21 can slide towards the lower side of the first sliding groove 25 to clamp the construction pile under the support of the inclined surface 24.

[0037] In this embodiment, the first support plate 21 is provided with a first sliding groove 25, which allows the first support plate 21 to slide relative to the first connecting rod 23. When the mounting base 1 is lowered, the first support plate 21 can slide upward along the first sliding groove 25. This sliding movement increases the distance between the first support plate 21 and the top plate 41, thereby loosening the pile. When the mounting base 1 is raised, the first support plate 21 and the top plate 41 work together to clamp the pile. During this process, the first support plate 21 slides downward along the first sliding groove 25. This sliding movement allows the first support plate 21 to clamp the pile more tightly under the support of the inclined surface 24.

[0038] In some embodiments, the second support member 3 includes a first drive cylinder 33, which is correspondingly disposed with the second support plate 31. The first drive cylinder 33 is connected to the mounting base 1, and the telescopic end of the first drive cylinder 33 is connected to a first rotating frame member 32. The first drive cylinder 33 is rotatably connected to the second support plate 31 through the first rotating frame member 32.

[0040] In some embodiments, the first rotating frame 32 includes a second frame 321, a first rotating frame 322, a second rotating frame 323, and a third rotating frame 324. The second frame 321 is connected to the mounting base 1. The first rotating frame 322 is rotatably connected to the second frame 321. One end of the second rotating frame 323 is rotatably connected to the first rotating frame 322, and the other end of the second rotating frame 323 is rotatably connected to the telescopic end of the first drive cylinder 33. The third rotating frame 324 is rotatably connected to the second rotating frame 323, and the third rotating frame 324 is rotatably connected to the second support plate 31.

[0041] In this embodiment, the second frame 321 is connected to the mounting base 1 to provide support and stability. The first rotating frame 322 is rotatably connected to the second frame 321, allowing the first rotating frame 322 to rotate relative to the second frame 321. Additionally, the installation of bearings or other similar mechanical structures at the rotating connection to achieve rotation should also fall within the scope of this application. One end of the second rotating frame 323 is rotatably connected to the first rotating frame 322, and the other end is rotatably connected to the telescopic end of the first drive cylinder 33. This connection allows the second rotating frame 323 to rotate simultaneously relative to both the first rotating frame 322 and the first drive cylinder 33. The third rotating frame 324 is rotatably connected to the second rotating frame 323 and also rotatably connected to the second support plate 31. This connection allows the third rotating frame 324 to rotate relative to both the second rotating frame 323 and the second support plate 31. The second frame 321, first rotating frame 322, second rotating frame 323, and third rotating frame 324 allow for better transmission of the driving force of the first drive cylinder 33 to the second support plate 31.

[0042] In some embodiments, the clamping drive member 42 includes a second drive cylinder 421, which is rotatably connected to the mounting base 1. The telescopic end of the second drive cylinder 421 is connected to a second rotating frame member 422, and the second drive cylinder 421 is rotatably connected to the top plate 41 through the second rotating frame member 422.

[0043] In this embodiment, the second rotating frame 422 is connected between the telescopic end of the second drive cylinder 421 and the top plate 41. It allows the top plate 41 to rotate relative to the second drive cylinder 421. The top plate 41 is one of the main working components of the clamping drive component 42. It works together with the first support plate 21 and the second support plate 31 to clamp or release the construction pile.

[0044] In some embodiments, a second connecting rod 4211 is connected to the second drive cylinder 421, and the second rotating frame 422 includes a fourth rotating frame 4221 and a fifth rotating frame 4222. One end of the fourth rotating frame 4221 is rotatably connected to the second connecting rod 4211, and the other end of the fourth rotating frame 4221 is rotatably connected to the top plate 41 corresponding to the first support plate 21. One end of the fifth rotating frame 4222 is rotatably connected to the second connecting rod 4211, and the other end of the fifth rotating frame 4222 is rotatably connected to the top plate 41 corresponding to the second support plate 31.

[0045] In this embodiment, the second connecting rod 4211 is connected to the second drive cylinder 421. The second rotating frame 422 consists of a fourth rotating frame 4221 and a fifth rotating frame 4222, which are responsible for transmitting the driving force to the top plate 41 corresponding to the first support plate 21 and the second support plate 31, respectively. One end of the fourth rotating frame 4221 is rotatably connected to the second connecting rod 4211, and the other end is rotatably connected to the top plate 41 (specifically, the part corresponding to the first support plate 21). This connection method allows the top plate 41 to rotate relative to the fourth rotating frame 4221. One end of the fifth rotating frame 4222 is also rotatably connected to the second connecting rod 4211, but the other end is rotatably connected to another top plate 41 (specifically, the part corresponding to the second support plate 31, if the top plate 41 is continuous or segmented). This connection method also allows the top plate 41 to rotate relative to the fifth rotating frame 4222. The second drive cylinder 421 transmits the driving force to the second rotating frame 422 through the second connecting rod 4211, and then transmits it to the top plate 41 corresponding to the first support plate 21 and the second support plate 31 through the fourth rotating frame 4221 and the fifth rotating frame 4222 respectively.

[0046] In some embodiments, the mounting base 1 is provided with a second sliding groove 11, and the second connecting rod 4211 is slidably connected to the second sliding groove 11.

[0047] In this embodiment, the second connecting rod 4211 is slidably connected to the second sliding groove 11. The second sliding groove 11 can guide the second connecting rod 4211 so that the telescopic end of the second drive cylinder 421 can perform stable telescopic movement.

[0048] In some embodiments, the seat lifting member 5 includes a moving track 51, a moving block 52, and a lifting cylinder 53. The moving track 51 is connected to the mounting base 1; the moving block 52 is slidably connected to the moving track 51; and the lifting cylinder 53 is connected to the moving block 52.

[0049] In this embodiment, in order to enable the lifting cylinder 53 to better lift the mounting base 1, the moving block 52 can drive the symmetrically arranged lifting cylinders 53 to move towards positions that are further apart and closer to each other.

[0050] In some embodiments, the moving track 51 is provided with a plurality of first positioning holes 511, and the moving block 52 is provided with a second positioning hole 521. The first positioning holes 511 and the second positioning holes 521 are configured such that when the moving block 52 moves to a suitable position, one of the plurality of first positioning holes 511 is aligned with the second positioning hole 521. At this time, a locking rod is used to pass through the first positioning hole 511 and the second positioning hole 521 to achieve positioning and locking.

[0051] In this embodiment, when it is necessary to fix the position of the symmetrically arranged lifting cylinders 53, after the moving block 52 is moved to the appropriate position and the first positioning hole 511 is aligned with the second positioning hole 521, the locking rod can be inserted to achieve locking. The locking rod can be rod-shaped or bolt-shaped, which will not be described in detail here.
