[0002] With the development of bridge construction technology, the scale of bridge construction is constantly expanding, and the requirements for the load-bearing capacity and seismic resistance of bridge pile foundations are also getting higher and higher. Therefore, the application of large-diameter and ultra-long piles in bridge construction is becoming more and more common, and the self-weight of steel cages is also getting heavier and heavier. When using traditional steel cage hoisting tools to install large-tonnage steel cages, various problems are prone to occur, which directly affect construction efficiency and personnel safety.

[0003] Existing equipment makes it difficult to adjust the number of hooks in a timely manner according to the length and weight of the steel cage during actual use, which may lead to dangers during operation. In addition, the equipment occupies a large area and has high requirements for the plane of the column foundation. Therefore, we propose a pile foundation steel cage support and hoisting device.

The sizes of the upper cover plate, lower cover plate, inner ring plate, and outer ring plate are adjusted according to the pile diameter and fixed by welding. The hook holes need to be pre-reserved in the inner ring plate and the outer ring plate, with eight pre-reserved holes. The lifting holes are welded to the outer ring plate. The hooks are made of welded steel plates, and the bolt holes are pre-reserved at the tail of the hooks.

[0006] Furthermore, the upper cover plate, lower cover plate, and lifting holes are made of 10mm steel plate.

[0007] Furthermore, the inner ring plate and the outer ring plate are made of 14mm steel plate.

[0008] Furthermore, the hook holes need to be pre-drilled on the inner and outer ring plates, with 16mm reinforcing ribs around the holes, and the hole diameter is 100mm×120mm. Eight pre-drilled holes are evenly arranged around the perimeter.

[0009] Furthermore, the upright plate of the hook is made of 16mm steel plate, and the upper and lower cover plates are welded together from 10mm steel plates. The hook is 110mm high and 800mm long. A groove is provided at the front end for placing the reinforcing bars of the steel cage, and a bolt hole is provided at the tail end.

[0010] Furthermore, when using the pile foundation reinforcement cage hoisting device, the hook needs to be inserted into the hook hole, and the bolt needs to be installed in the bolt hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting the upper cover plate and the lower cover plate, when the length and weight of the steel cage change during use, the number of hooks can be adjusted in time, which is convenient for different steel cage hoisting operations. Through the above design, the steel cage hoisting operation can be completed quickly, which is convenient, fast and improves work efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3A pile foundation reinforcement cage support and hoisting device includes an upper cover plate 1, a lower cover plate 2, an inner ring plate 3, an outer ring plate 4, hook holes 5, lifting holes 6, hooks 7, and bolt holes 8. The sizes of the upper cover plate 1, lower cover plate 2, inner ring plate 3, and outer ring plate 4 are adjusted according to the pile diameter and fixed by welding. The hook holes 5 need to be pre-drilled on the inner ring plate 3 and outer ring plate 4, with eight pre-drilled holes. The lifting holes 6 are welded to the outer ring plate 4. The hooks 7 are made of welded steel plates. The bolt holes 8 are pre-drilled at the tail of the hooks 7. The upper cover plate 1, lower cover plate 2, and lifting holes 6 are made of 10mm steel plates. The inner ring plate 3 and outer ring plate 4 are... 4. 14mm steel plate is used. Hook holes 5 need to be reserved in the inner ring plate 3 and the outer ring plate 4. 16mm reinforcing plate is used around the holes. The hole diameter is 100mm×120mm. Eight reserved holes are evenly arranged around the perimeter. The upright plate of hook 7 is made of 16mm steel plate. The upper cover plate 1 and the lower cover plate 2 are both welded from 10mm steel plates. The hook 7 is 110mm high and 800mm long. The front end of hook 7 is provided with a groove for placing the reinforcing bars of the steel cage. The tail end is provided with bolt holes 8. When the pile foundation steel cage hoisting device is in use, hook 7 needs to be inserted into hook hole 5 and bolts are installed in bolt hole 8.

[0018] Specifically, before using this device for rebar cage hoisting, the dimensions of the upper cover plate of part 1, the lower cover plate of part 2, the inner ring plate of part 3, and the outer ring plate of part 4 need to be adjusted according to the pile diameter. After adjustment, these parts are fixed together by welding to form the main frame of the device. Eight hook holes of part 5 are pre-arranged evenly around the perimeter on the inner ring plate of part 3 and the outer ring plate of part 4. The diameter of these hook holes is 100mm×120mm, and 16mm stiffening plates are welded around the holes to enhance strength. The lifting holes of part 6 have also been welded to the outer ring plate of part 4 for connecting the hoisting equipment. Next, the number of hooks of part 7 to be used is determined according to the length and weight of the rebar cage. The upright plate of the hook of part 7 is made of 16mm steel plate, and the upper and lower cover plates are made of 10mm steel plate. Its height is 110mm and its length is 800mm. The front end is equipped with The device has a groove and pre-drilled bolt holes for part 8 at the tail. Insert the selected number of part 7 hooks one by one into the corresponding part 5 hook holes. After insertion, install bolts in the part 8 bolt holes to firmly fix the hooks on the hook holes to prevent them from falling off during hoisting. Once everything is ready, connect the hoisting equipment to the lifting hole of part 6. Then operate the hoisting equipment to align the groove at the front end of the part 7 hook with the reinforcing bars of the rebar cage and place the reinforcing bars into the groove. After confirming that the rebar cage is placed stably, start the hoisting equipment to slowly lift the rebar cage and move it above the pile foundation construction position. Throughout the hoisting process, pay close attention to the status of each part of the device to ensure hoisting safety. When the rebar cage is accurately lowered to the designated position in the pile foundation, operate the hoisting equipment to separate the part 7 hook from the rebar cage, completing this rebar cage hoisting operation. The above steps can be repeated for the next hoisting requirement.
