This invention can reduce the requirements for site size and on-site scheduling, as well as reduce the consumption of manpower and material resources, and also help to eliminate or reduce safety hazards during construction.

[0004] The steel cage hoisting device in the aforementioned patent still has some shortcomings. When hoisting existing diaphragm wall steel cages, two sets of cranes are usually used in combination. However, the hooks on the cranes are usually tied to the hooks and the steel cages with wire ropes respectively. This connection method results in a small contact area between the hooks and the steel cages, which makes it easy for the steel cages to shift and sway during actual hoisting, thus increasing the difficulty of installing the steel cages. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a hoisting device for diaphragm wall reinforcement cages. This solves the problem that existing diaphragm wall reinforcement cages are typically hoisted using two sets of cranes. However, the hooks on the cranes are usually tied to the reinforcement cage with wire ropes, resulting in a small contact area between the hooks and the reinforcement cage. Consequently, during actual hoisting, the cage is prone to shifting and swaying, which increases the difficulty of installing the reinforcement cage.

[0006] This utility model provides the following technical solution: a diaphragm wall steel cage hoisting device, including a steel cage assembly, a stable hoisting component is provided on the top of the steel cage assembly, and a hook assembly is provided on the top of the stable hoisting component;

[0007] The steel cage assembly includes several uniformly arranged steel bars. Several steel bar limiting frames are uniformly fitted on the outer side of the steel bars. Several first steel bar limiting rods are vertically arranged on the inner wall of each steel bar limiting frame. Two second steel bar limiting rods are uniformly arranged at the corners around the steel bar limiting frame.

[0008] The stable hoisting assembly includes a support connecting plate disposed on the top of the rebar cage assembly. Two symmetrical side rotating slots are formed at the bottom of both sides of the support connecting plate. A rotating connecting plate is inserted into each of the side rotating slots. The two ends of each rotating connecting plate are rotatably connected to the inner wall of the side rotating slot via rotating connecting blocks. A side crossbar is provided at the end of each rotating connecting plate. Two fixed connecting blocks are symmetrically arranged on the side of each side crossbar. A rotating insert is movably inserted through the end of each rotating connecting plate. The ends of each rotating insert are rotatably connected to the fixed connecting blocks. Three rebar hooks are evenly arranged on the other side of each side crossbar. A top hook ring is fixed to the top of the support connecting plate.

[0009] Preferred technical solution 1: The hook assembly includes a wire connecting plate disposed on the top of the support connecting plate, side connecting plates are rotatably disposed on both sides of the wire connecting plate, a hook is disposed at the bottom of the wire connecting plate, the top end of the hook is rotatably connected to the bottom end of the side connecting plate through a pin, and the bottom end of the hook is inserted into the top hook ring.

[0010] Preferred technical solution 2: A sliding groove is provided on the side of the end of the hook, and an abutment rod is slidably inserted in the sliding groove. Several abutment grooves are evenly provided on the side of the abutment rod, and an abutment bolt is threaded into the side of the end of the hook, with the end of the abutment bolt extending into the sliding groove.

[0011] Preferred technical solution 3: Several of the steel bars are evenly distributed on the inner sidewall of the steel bar limiting frame and connected by steel wire.

[0012] This solution makes the connection between the reinforcing bar and the reinforcing bar limiting frame more stable.

[0013] Preferred technical solution four: The steel bar hook has an L-shaped bend in its longitudinal section.

[0014] This solution enables the rebar hooks to better attach to the sides of the rebar limit frame.

[0015] Preferred technical solution five: The diameter of the abutting bolt is smaller than the inner diameter of the abutting groove.

[0016] This design allows the contact bolts to be inserted into the contact grooves for fixation.

[0017] Compared with the prior art, this utility model provides a hoisting device for diaphragm wall steel cages, which has the following features:

[0018] Beneficial effects:

[0019] (1) This utility model provides a stable hoisting component and a hook component on the steel cage assembly. After the hook in the hook component passes through the top hook ring, it can also close the side of the hook by pulling the abutment bar upward, thus ensuring the connection stability between the hook and the top hook ring. The side of the steel hook is hooked onto the steel limit frame in sequence. By hooking multiple steel hooks onto the steel limit frame, the contact area during hoisting is increased, which makes the steel cage assembly more stable during hoisting, greatly reducing the risk of shaking during hoisting, and thus reducing the difficulty of installing the steel cage assembly, making it more convenient for users to hoist, install and use.

[0028] Please see Figure 1-4 ,

[0029] Example 1: A diaphragm wall rebar cage hoisting device, including a rebar cage assembly 1, a stable hoisting assembly 2 on the top of the rebar cage assembly 1, and a hook assembly 3 on the top of the stable hoisting assembly 2;

[0030] The steel cage assembly 1 includes several uniformly arranged steel bars 101. Several steel bar limiting frames 102 are uniformly fitted on the outer side of the steel bars 101. Several first steel bar limiting rods 103 are vertically arranged on the inner wall of each steel bar limiting frame 102. Two second steel bar limiting rods 104 are uniformly arranged at the corners of the steel bar limiting frame 102.

[0031] The stable hoisting assembly 2 includes a support connecting plate 201 set on the top of the rebar cage assembly 1. Two side rotating grooves 202 are symmetrically opened at the bottom of both sides of the support connecting plate 201. A rotating connecting plate 203 is inserted into each side rotating groove 202. The two sides of the end of the rotating connecting plate 203 are rotatably connected to the inner wall of the side rotating groove 202 through a rotating connecting block 204. A side crossbar 205 is set at the end of the rotating connecting plate 203. Two fixed connecting blocks 206 are symmetrically arranged on the side of the side crossbar 205. A rotating insert rod 207 is movably inserted through the end of the rotating connecting plate 203. The ends of the rotating insert rods 207 are rotatably connected to the fixed connecting blocks 206. Three rebar hooks 208 are evenly arranged on the other side of the side crossbar 205. A top hook ring 209 is fixed at the top of the support connecting plate 201.

[0032] The hook assembly 3 includes a wire connecting plate 301 disposed on the top of the support connecting plate 201. Side connecting plates 302 are rotatably disposed on both sides of the wire connecting plate 301. A hook 303 is disposed at the bottom of the wire connecting plate 301. The top end of the hook 303 is rotatably connected to the bottom end of the side connecting plate 302 by a pin. The bottom end of the hook 303 is inserted into the top hook ring 209. A sliding groove 304 is provided on the side of the end of the hook 303. An abutment bar 305 is slidably inserted in the sliding groove 304. Several abutment grooves 306 are evenly provided on the side of the abutment bar 305. An abutment bolt 307 is threadedly inserted on the side of the end of the hook 303. The end of the abutment bolt 307 extends into the sliding groove 304.

[0033] Example 2: The difference between this example and Example 1 is that several steel bars 101 are evenly distributed on the inner side wall of the steel bar limiting frame 102 and connected by steel wire.

[0034] This makes the connection between the steel bar 101 and the steel bar limiting frame 102 more stable.

[0035] Example 3: The difference between this example and Example 1 is that the steel bar hook 208 has an L-shaped bend in its longitudinal section.

[0036] This allows the rebar hook 208 to better attach to the side of the rebar limit frame 102.

[0037] Example 4: The difference between this example and Example 1 is that the diameter of the contact bolt 307 is smaller than the inner diameter of the contact groove 306.

[0038] This allows the contact bolt 307 to be inserted into the contact groove 306 for fixation.

[0039] In this embodiment, when the existing diaphragm wall reinforcement cage is hoisted, two sets of cranes are usually used to hoist it together. However, the hooks on the cranes are usually tied to the hooks and the reinforcement cage with wire ropes respectively. This connection method has a small contact area with the reinforcement cage, which makes it easy for the cage to shift and sway during the actual hoisting process, thus increasing the difficulty of installing the reinforcement cage.

[0040] In summary, during specific implementation, when the user needs to hoist and install the rebar cage assembly 1, the user first installs the wire connecting disc 301 from the hook assembly 3 onto the end of the crane, connecting the steel cable on the crane to the wire connecting disc 301. The hook 303 at the bottom of the wire connecting disc 301 passes through the middle of the top hook ring 209. By pulling the abutment bar 305 inserted in the sliding groove 304 upwards and rotating the abutment bolt 307, the end of the abutment bolt 307 can be inserted into the abutment groove 306, thereby closing the side of the hook 303 and making the hook 303 more stable in the top hook ring 209.

[0041] The rebar hooks 208 in the stable hoisting assembly 2 are hooked sequentially on both sides of the rebar limiting frame 102. Since the side crossbar 205 and the rotating connecting plate 203 are rotatably connected by the rotating insert 207, and the rotating connecting plate 203 and the support connecting plate 201 are rotatably connected by the rotating connecting block 204, the rebar hooks 208 can be appropriately deflected when the support connecting plate 201 is lifted by the crane. This allows the rebar hooks 208 to be stably locked on the side of the rebar limiting frame 102, making it easier for users to hoist the rebar cage assembly 1.

[0042] By evenly arranging three steel bar hooks 208 on the side of the side crossbar 205, the steel bar hooks 208 can hook onto the side of the steel bar limiting frame 102 respectively, which greatly increases the contact area between the steel bar hooks 208 and the steel bar limiting frame 102. This makes the steel bar cage assembly 1 more stable when it is hoisted, greatly reduces the risk of shaking when the steel bar cage assembly 1 is hoisted, and thus reduces the difficulty of installing the steel bar cage assembly 1, making it more convenient for users to hoist, install and use.
