[0001] The utility model relates to the technical field of hoisting, in particular to an auxiliary hoisting device suitable for a cast-in-place pile guide pipe. Background Art

[0002] With the rapid development of engineering construction in my country, pile foundations are mostly used in high-rise buildings, industrial plants, heavy equipment foundations, highway and railway bridges and other projects. Bored cast-in-place piles are widely used due to their wide applicability and high bearing capacity.

[0003] At present, bored piles are drilled by rotary drilling rigs, submersible drilling rigs and other equipment. Mud wall protection is used to protect the stability of the hole wall. After the hole is drilled, the steel cage is lowered to position and fix it, and then the steel conduit is placed. When concrete is poured, the pile foundation is gradually formed through the inner wall of the conduit. However, when the conduit is hoisted by wire rope, the wire rope and the bored pile conduit are easy to slip, which causes the wire rope and conduit to easily deviate from the position of the steel cage, resulting in low conduit hoisting efficiency.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are 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.

[0030] The embodiment of the present application provides an auxiliary lifting device suitable for the bored pile conduit, which solves the problem that the wire rope and the bored pile conduit are easy to slip, causing the wire rope and the conduit to easily deviate from the position of the steel cage and the conduit, resulting in low conduit lifting efficiency, thereby achieving efficient lifting of the conduit.

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Example:

[0033] like Figure 1-Figure 3 As shown, an auxiliary lifting device suitable for a bored pile conduit is used for lifting a bored pile conduit 40, and the lifting device includes a lifting beam 10 and a steel wire rope 30;

[0034] The hoisting crossbeam 10 is provided with a hoisting hole 101 and two horizontal holes 102;

[0035] The lifting device further comprises a semi-ring member 20, and the semi-ring member 20 is provided with two through holes 201;

[0036] The cast-in-place pile conduit 40 is provided with a first limiting ring 41 and a second limiting ring 42;

[0037] In the hoisting state, the half ring 20 is located between the first limiting ring 41 and the second limiting ring 42 , and abuts against the first limiting ring 41 .

[0038] By setting up the semi-ring member 20, during hoisting, the two ends of the steel wire rope 30 pass through the two through holes 201 respectively. After the steel wire rope 30 passes through the through holes 201 and passes through the corresponding horizontal holes 102, the steel wire rope 30 is closed, and the semi-ring member 20 is combined with the steel wire rope 30 and sleeved on the bored pile guide tube 40. The hoisting operation of the bored pile guide tube 40 is realized by using the hoisting crossbeam 10, which improves the stability during the hoisting process and solves the problem that the steel wire rope 30 and the bored pile guide tube 40 are easy to slide, which causes the steel wire rope 30 and the bored pile guide tube 40 to easily deviate from the position of the steel cage, thereby resulting in low hoisting efficiency of the bored pile guide tube 40.

[0039] The semi-ring member 20 is provided with a closed handle 22, and a traction rope 31 is installed on the closed handle 22. The traction rope 31 is detachably connected to the semi-ring member 20 through a buckle. By providing the closed handle 22 and the traction rope 31, the traction rope 31 remotely controls the lifting position during lifting, further improving the lifting accuracy, and effectively reducing the position deviation during the lifting process. The cast-in-place pile guide tube 40 is quickly fixed by the traction rope 31 with a buckle, which is convenient for safe lifting.

[0040] The semi-ring member 20 is provided with a hand-held handle 21, through which the operator can quickly install the semi-ring member 20 on the bored pile guide tube 40, avoiding squeezing or pinching of the operator when installing the guide tube using a lifting tool.

[0041] like Figure 4 As shown, the semi-ring members 20 are provided in plurality, and a plurality of mounting holes 202 are opened on the semi-ring members 20. Two adjacent semi-ring members 20 are fixed by connecting members 23 passing through corresponding mounting holes 202, thereby further improving the stability of the cast-in-place pile guide tube 40 during hoisting.

[0042] Specifically, the connecting member 23 includes two blocks 231 and two nuts 232 , so as to fix the two adjacent half-ring members 20 by the connecting member 23 .

[0043] The semi-ring member 20, the hand-held handle 21 and the closed handle 22 are integrally formed.

[0044] Specifically, the perforation 201 is chamfered at 45°, which improves the smoothness of the steel wire rope 30 when sliding, prolongs the service life of the steel wire rope 30, and improves the safety of the auxiliary tool.

[0045] When in use, the connecting piece 23 is located between two adjacent semi-ring pieces 20. At least two connecting pieces 23 are provided. Multiple connecting pieces 23 are placed in one of the semi-ring pieces 20 and fixed by a nut 232. Then, the adjacent semi-ring piece 20 is installed to the other end of the connecting piece 23 and fixed by a nut 232 to complete the installation operation of the two adjacent semi-ring pieces 20. After the installation is completed, the steel wire rope 30 passes through the through hole 201 on the semi-ring piece 20 and is closed after passing through the horizontal hole 102. At this time, the steel wire rope 30 and the semi-ring piece 20 form a closed loop and are arranged in the cast-in-place pile guide pipe, and the cast-in-place pile guide pipe 40 is hoisted.

[0046] The bored pile conduit 40 after hoisting is placed in the steel cage in the grouting hole. At this time, the second limiting ring 42 on the bored pile conduit 40 is located on the support plate on the steel cage to support the entire bored pile conduit 40. At this time, the hand-held handle 21 contacts the half-ring 20 and the steel wire rope 30 to limit the bored pile conduit 40, completing the entire hoisting process.

[0047] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0048] 1. The semi-ring member 20 is provided to solve the problem that the wire rope 30 and the bored pile guide tube 40 are easy to slide, which causes the wire rope 30 and the bored pile guide tube 40 to easily deviate from the position of the steel cage, thereby reducing the lifting efficiency of the bored pile guide tube 40.

[0049] 2. By setting up the closed handle 22 and the traction rope 31, the far end of the traction rope 31 controls the lifting position during lifting, further improving the lifting accuracy and effectively reducing the position deviation during the lifting process. The traction rope 31 with a buckle can quickly fix the bored pile guide tube 40, which is convenient for safe lifting.

[0050] 3. The hand-held handle 21 on the semi-ring member 20 allows the operator to quickly install the semi-ring member 20 on the cast-in-place pile guide tube 40, thereby avoiding squeezing or pinching of the operator when installing the guide tube using a lifting tool.
