Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile cutting and lifting construction technology, and in particular to a pile head lifting device. Background Technology

[0002] Currently, during the construction of the high-pile wharf, steel pipe piles need to be installed. However, due to the different geological conditions at different locations, the depth to which the steel pipe piles extend into the water varies, resulting in inconsistent top heights of the steel pipe piles. Later, a pile-cutting platform needs to be set up so that operators can cut the top of the steel pipe piles on the platform, cutting off and lifting off the excess portion (pile head) so that the top of all remaining steel pipe piles is at the designed height.

[0003] During the process of lifting the pile head, it is necessary to connect the pile head to the hoisting structure. The commonly used method is to weld lifting lugs or drill holes on the top of the steel pipe pile when it is placed on the ground before the steel pipe pile is lifted and driven. After the pile is cut, the construction personnel reach the top of the pile head and connect the hoisting structure to the lifting lugs or drill holes. However, sometimes when encountering complex geological conditions, some pile heads are 2-5m high. In this case, it is necessary to build a temporary platform on or above the pile head to allow the construction personnel to reach the top of the pile head. The whole process is time-consuming, laborious, and extremely inefficient. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem in the prior art that when the height of the pile head to be cut and lifted is high, a temporary platform needs to be built on the pile head or the upper part, which is time-consuming, laborious and inefficient. This invention provides a pile head lifting device.

[0005] In a first aspect, the present invention provides a pile head hoisting device, wherein the top of the pile head is open and includes a first hoisting rope assembly and a hook. At least one side of the bottom of the pile head has a through hole. A portion of the first hoisting rope assembly extends into the pile head from the open top of the pile head to form a U-shaped portion, and the U-shaped portion extends out of the through hole. The lower end of the first hoisting rope assembly passes around the top of the pile head and is connected to the hook on the outside of the pile head. The U-shaped portion and the hook are engaged.

[0006] The pile head hoisting device described in this application involves lowering a first hoisting rope assembly. A portion of the first hoisting rope assembly extends into the pile head through the open top to form a U-shaped section. The U-shaped section passes through a through hole and engages with a hook on the outside of the pile head. Simultaneously, the lower end of the first hoisting rope assembly wraps around the top of the pile head and connects to the hook on the outside of the pile head. This forms a closed loop with the U-shaped section, the lower end of the first hoisting rope assembly, and the hook, achieving connection between the pile head hoisting device and the pile head without tipping over. This achieves the purpose of hoisting the pile head. Furthermore, the through hole is located at the bottom of the pile head. After the first hoisting rope assembly and hook are lowered to a certain extent, the operator uses their arm or tools to hook the U-shaped section out of the through hole and engage it with the hook. The entire process can utilize existing pile cutting platforms, eliminating the need to erect temporary platforms at or above the pile head. This saves time and effort and effectively improves construction efficiency.

[0007] Preferably, the first lifting rope assembly includes a first lifting rope, a portion of which extends into the pile head from the open portion at the top of the pile head to form the U-shaped section; the end of the first lifting rope wraps around the top of the pile head and is connected to the hook. The first lifting rope not only forms the U-shaped section but also connects to the hook, resulting in a simple structure and convenient construction.

[0008] Preferably, the portion of the first suspension rope located at the upper part of the U-shaped section is secured with cable ties.

[0009] Preferably, the first hoisting rope assembly includes a first hoisting rope and a second hoisting rope connected to each other, wherein:

[0010] The end of the first suspension rope is wrapped back and connected to the middle of the first suspension rope, so that a part of the first suspension rope forms a closed loop structure, and the lower part of the loop structure forms the U-shaped part;

[0011] The upper end of the second lifting rope is connected to the first lifting rope, and the lower end of the second lifting rope is connected to the hook; the position where the upper end of the second lifting rope is connected to the first lifting rope is above the pile head.

[0012] Preferably, a support structure is connected to the second lifting rope, the support structure spreading the first and second lifting ropes apart so that a gap can be formed between the U-shaped part and the hook; when the top of the pile head abuts against the support structure, the support structure can generate upward elastic deformation.

[0013] The first and second lifting ropes are spread apart by the support structure, so that a gap can be formed between the U-shaped part and the hook. This makes it easy for the side wall of the pile head to enter between the first and second lifting ropes through the gap during lowering, further reducing the construction difficulty. When the top of the side wall of the pile head touches the support structure, the support structure can generate upward elastic deformation, which causes the support structure to deform, thereby bringing the first and second lifting ropes closer together, which is more conducive to the connection between the U-shaped part and the hook.

[0014] Preferably, the support structure includes a connecting sleeve, a plate, and a backing part connected in sequence. The backing part abuts against the first lifting rope through an arc-shaped surface, and the connecting sleeve is sleeved and connected to the outside of the second lifting rope.

[0015] Preferably, the plate and the abutment are integrally formed.

[0016] Preferably, both the plate and the abutment are structural components made of rubber.

[0017] Preferably, the integral formed by the plate and the abutment can be cut and shaped from the Ω seal.

[0018] Preferably, it also includes a steel pipe pile, the upper part of which is divided into two parts: the pile and the pile head. The pile head is located above the pile body, and the through hole is located on the cutting path, which greatly reduces the extra workload caused by the through hole opening operation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The pile head hoisting device described in this application involves lowering a first hoisting rope assembly. A portion of the first hoisting rope assembly extends into the pile head through the open top to form a U-shaped section. The U-shaped section passes through a through hole and engages with a hook on the outside of the pile head. Simultaneously, the lower end of the first hoisting rope assembly wraps around the top of the pile head and connects to the hook on the outside of the pile head. This forms a closed loop with the U-shaped section, the lower end of the first hoisting rope assembly, and the hook, achieving connection between the pile head hoisting device and the pile head without tipping over. This achieves the purpose of hoisting the pile head. Furthermore, the through hole is located at the bottom of the pile head. After the first hoisting rope assembly and hook are lowered to a certain extent, the operator uses their arm or tools to hook the U-shaped section out of the through hole and engage it with the hook. The entire process can utilize existing pile cutting platforms, eliminating the need to erect temporary platforms at or above the pile head. This saves time and effort and effectively improves construction efficiency. Attached Figure Description

[0036] like Figure 1-8 As shown in the figure, this embodiment provides a pile head hoisting device of the present invention. The pile head 3 has an open top and includes a first hoisting rope assembly 1 and a hook 2. At least one side of the bottom of the pile head 3 has a through hole 10. A part of the first hoisting rope assembly 1 extends into the pile head 3 from the open top of the pile head 3 to form a U-shaped part 13. The U-shaped part 13 passes through the through hole 10. The lower end of the first hoisting rope assembly 1 passes around the top of the pile head 3 and is connected to the hook 2 on the outside of the pile head 3. The U-shaped part 13 and the hook 2 are hooked together.

[0037] The pile head hoisting device described in this application, when lowering the first hoisting rope assembly 1, a portion of the first hoisting rope assembly 1 extends into the pile head 3 through the open top of the pile head 3 to form a U-shaped portion 13. The U-shaped portion 13 passes through the through hole 10 and is hooked to the hook 2 on the outside of the pile head 3. At the same time, the lower end of the first hoisting rope assembly 1 wraps around the top of the pile head 3 and connects to the hook 2 on the outside of the pile head 3, thereby making the U-shaped portion 13, the lower end of the first hoisting rope assembly 1, and the hook 2 surround the pile head 3. The system forms a closed loop, connecting the pile head hoisting device to the pile head 3 without tipping over, thus achieving the purpose of hoisting the pile head 3. Furthermore, the through hole 10 is opened at the bottom of the pile head 3. After the first hoisting rope assembly 1 and the hook 2 are lowered to a certain extent, the operator uses their arm or tools to hook the U-shaped part 13 out of the through hole 10 and connect the U-shaped part 13 to the hook 2. The entire process can utilize the existing pile cutting platform, eliminating the need to build a temporary platform at the pile head or above. The entire process is convenient and labor-saving, effectively improving construction efficiency.

A portion of the first hoisting rope 11 extends into the pile head 3 from the open top of the pile head 3 to form the U-shaped portion 13. The end of the first hoisting rope 11 wraps around the top of the pile head 3 and is connected to the hook 2. The first hoisting rope 11 not only forms the U-shaped portion 13 but also connects to the hook 2, resulting in a simple structure and convenient construction.

[0040] More preferably, the portion of the first suspension rope 11 located on the upper part of the U-shaped section 13 is tied and connected by a binding strap 6.

[0041] Example 3

[0042] like Figure 4-8 As shown, this embodiment provides a pile head hoisting device. The difference between this embodiment and Embodiment 2 is that, preferably, the first hoisting rope assembly 1 includes a first hoisting rope 11 and a second hoisting rope 12 connected together, wherein:

[0043] The end of the first suspension rope 11 is wrapped back and connected to the middle of the first suspension rope 11, so that a part of the first suspension rope 11 forms a closed loop structure, and the lower part of the loop structure forms the U-shaped part 13;

[0044] The upper end of the second lifting rope 12 is connected to the first lifting rope 11, and the lower end of the second lifting rope 12 is connected to the hook 2; the position where the upper end of the second lifting rope 12 is connected to the first lifting rope 11 is above the pile head 3.

[0045] Preferably, a support structure 4 is connected to the second hoisting rope 12, the support structure 4 spreading the first hoisting rope 11 and the second hoisting rope 12 apart so that a gap 15 can be formed between the U-shaped part 13 and the hook 2; when the top of the pile head 3 abuts against the support structure 4, the support structure 4 can generate an upward elastic deformation.

[0046] The first and second lifting ropes 11 and 12 are spread apart by the support structure 4, so that a gap 15 can be formed between the U-shaped part 13 and the hook 2. This makes it easier for the side wall of the pile head 3 to enter between the first and second lifting ropes 11 and 12 through the gap 15 during lowering, further reducing the construction difficulty. When the top of the side wall of the pile head 3 touches the support structure 4, the support structure 4 can generate upward elastic deformation, which causes the support structure 4 to deform, thereby bringing the first and second lifting ropes 11 and 12 closer together, which is more conducive to the connection between the U-shaped part 13 and the hook 2.

[0047] Preferably, the support structure 4 includes a connecting sleeve 41, a plate 42 and abutting part 43 connected in sequence. The abutting part 43 abuts against the first suspension rope 11 through an arc-shaped surface 44, and the connecting sleeve 41 is sleeved and connected to the outside of the second suspension rope 12.

[0048] Preferably, the plate 42 and the abutment part 43 are integrally formed.

The pile head 3 is located above the pile body 9, and the through hole 10 is located on the cutting path, which greatly reduces the extra workload caused by the drilling of the through hole 10.

[0052] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
