Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a large-diameter pipe pile hanging pile supporting device. Background Art

[0002] Large diameter pipe piles are large diameter pipe piles, which are generally larger than one meter in diameter. They can withstand large vertical forces, horizontal forces and torques, and have good deformation control capabilities. Large diameter pipe piles play an important role in supporting infrastructure such as highways and large bridges, ensuring the firmness and stability of buildings.

[0003] During the construction and installation of large-diameter pipe piles, the piles stacked together need to be lifted by a hook crane. The traditional method is to first lift the pipe pile with the hook of the crane, and then tie the lifting device firmly. Since the hook directly acts on the inner wall of the pipe pile when the pipe pile is lifted, it will cause damage to the floating slurry on the inner wall of the pipe pile. In addition, the stability of the hook directly hooked on the pipe pile is poor, and it is impossible to lift the pipe pile safely and without damage. Utility Model Content

[0004] The utility model aims to propose a large diameter pipe pile lifting and supporting device in order to solve the problem that the existing large diameter pipe pile lifting and supporting will cause damage to the inner wall of the pipe pile and cannot achieve safe and lossless lifting and supporting of the pipe pile.

[0007] And a hoisting assembly arranged at the end of the pile body, the hoisting assembly comprises a fixing plate detachably mounted on the pile body by connecting bolts, and a hanging ear integrally formed with the fixing plate is arranged on the top of the fixing plate.

[0008] As a further description of the above technical solution: the connecting bolts pass through the fixing plate through the connecting screw holes, and end plates are provided at both ends of the pile body, and bolt holes matching with the connecting bolts are opened on the end plates.

[0009] As a further description of the above technical solution: the number of the bolt holes is several and they are distributed in a ring array on the ring-shaped end plate.

[0010] As a further description of the above technical solution: the fixing plate is arranged in an arc shape, and the center of the fixing plate coincides with the axis of the pile body;

[0011] The number of the connecting screw holes is several, and the spacing between adjacent connecting screw holes on the fixing plate is the same as the spacing between adjacent bolt holes on the end plate.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1-Figure 5 A large-diameter pipe pile hanging and supporting device provided in this embodiment includes a pile body 1 and a lifting assembly 2 arranged at the end of the pile body 1. The lifting assembly 2 includes a fixing plate 21 detachably mounted on the pile body 1 by connecting bolts 24, and a hanging ear 22 integrally formed therewith is provided on the top of the fixing plate 21.

[0027] In the utility model, when it is necessary to lift the stacked large-diameter pipe piles for hoisting, the fixing plate 21 is fixedly installed at the end position of the pile body 1 by using the connecting bolts 24, and the hanging ear 22 integrally formed with the fixing plate 21 protrudes from the outside of the pile body 1, and then the hook of the hook crane is connected to the hanging ear 22, and the pile body 1 is lifted by the crane. The fixing plate 21 and the hanging ear 22 can prevent the hook of the crane from directly acting on the inner wall of the pipe pile to cause damage to the slurry on the inner wall of the pipe pile, thereby achieving safe and lossless lifting and lifting of the pipe pile.

[0028] Specifically, Figure 2-Figure 4 As shown, the connecting bolts 24 pass through the fixing plate 21 through the connecting screw holes 23 , and end plates 11 are provided at both ends of the pile body 1 , and bolt holes 12 matching with the connecting bolts 24 are opened on the end plates 11 .

[0029] Among them, when the stacked pipe piles need to be lifted, the fixing plate 21 is attached to the end plate 11 of the pile body 1, and then the connecting bolts 24 are passed through the connecting screw holes 23 of the fixing plate 21 and connected to the bolt holes 12, so that the hanging ears 22 on the fixing plate 21 are fixed on the pile body 1, ensuring that the hook of the crane can be connected to the hanging ears 22, and the fixing plate 21 and the hanging ears 22 installed by the connecting bolts 24 can be disassembled, so that the large-diameter pipe pile lifting and supporting device can be disassembled and reused.

[0030] Specifically, Figure 1 and Figure 2 As shown, the number of bolt holes 12 is several and they are distributed in a circular array on the annular end plate 11. The bolt holes 12 distributed in a circular pattern with equal spacing on the end plate 11 can be installed in any direction when the fixing plate 21 is installed. When the large-diameter pipe pile is lifted, there is no need to find a specific installation point of the pile-holding device, which facilitates the installation of the pile-holding device and facilitates lifting of the large-diameter pipe pile.

[0031] Specifically, Figure 1-Figure 4 As shown, the fixing plate 21 is arranged in an arc shape, and the center of the fixing plate 21 coincides with the axis of the pile body 1;

[0032] There are a plurality of connecting screw holes 23 , and the spacing between adjacent connecting screw holes 23 on the fixing plate 21 is the same as the spacing between adjacent bolt holes 12 on the end plate 11 .

[0033] Among them, the spacing of the connecting screw holes 23 is the same as the spacing of the bolt holes 12. When the fixing plate 21 is installed, the bolt holes 12 at any position of the pile body 1 can cooperate with the connecting screw holes 23 on the fixing plate 21, so that the pile supporting device can be installed at multiple angles according to the stacking and lifting needs of the pipe piles on site. There is no need to find a specific installation point of the pile supporting device when lifting large-diameter pipe piles.

[0034] It should be noted that the top corners of the fixing plate 21 are rounded, which can effectively remove sharp corners and reduce the risk of injury caused by collision during installation, maintenance or use of the fixing plate 21.

[0035] Specifically, Figure 3 and Figure 5 As shown, a lifting ring 26 for connecting a steel cable is provided on the hanging ear 22 through a hanging hole 25 , and the lifting ring 26 includes a U-shaped rod 261 , and a pin shaft 263 penetrating the hanging hole 25 is provided at the bottom of the U-shaped rod 261 through a connecting seat 262 .

[0036] Among them, the U-shaped rod 261 is rotatably installed on the hanging ear 22 through the pin shaft 263 on the connecting seat 262. When the lifting ring 26 is used to connect the steel rope of the crane, the rotating lifting ring 26 can facilitate the fastening of the steel rope to the lifting ring 26, so that the pile supporting device can be conveniently connected to the steel rope of the crane.

[0037] It should be noted that the fixing plate 21 and the hanging ear 22 are both made of stainless steel. The fixing plate 21 and the hanging ear 22 made of stainless steel have excellent corrosion resistance, so they can adapt to the installation environment of the pipe pile and extend the service life of the pile supporting device. Moreover, the fixing plate 21 and the hanging ear 22 made of stainless steel have high strength and hardness, so when the pile supporting device is used to support the pipe pile, the pile supporting device can be prevented from breaking.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
