Description

Technical Field

[0001] This application relates to the field of steel cage hoisting technology, and in particular to an integral hoisting device and construction method for steel cages of ultra-deep underground continuous walls. Background Technology

[0002] In the field of super high-rise building construction, diaphragm walls have become an effective technology for seepage prevention, soil retention and load-bearing in underground engineering and deep foundation construction, and the hoisting of the diaphragm wall reinforcement cage is a very important step.

[0003] Traditional methods for hoisting steel cages for diaphragm walls typically involve single-point lifting. During hoisting, construction workers secure slings to the steel cage, and then a crane is used to lift the cage.

[0004] During the lifting process, the single-point lifting method can easily cause the steel cage to become unstable. Furthermore, the manual fixing process by construction workers may result in insecure fixing and other safety hazards. This can lead to safety risks such as crane instability and the steel cage falling from a height and injuring people. Therefore, targeted improvements need to be made to the steel cage lifting device. Summary of the Invention

[0005] To improve the safety of the rebar cage hoisting process, this application provides an integral hoisting device and construction method for rebar cages in ultra-deep underground continuous walls.

[0006] The overall hoisting device for the steel cage of ultra-deep underground continuous wall provided in this application adopts the following technical solution: An integral hoisting device for ultra-deep underground continuous wall reinforcement cages is disclosed for hoisting the reinforcement cage body. It includes a clamping seat, a clamping mechanism disposed within the clamping seat, and a hoisting mechanism for hoisting the clamping seat. Two sets of clamping seats are arranged corresponding to the two sides of the reinforcement cage body. Each set of clamping seats contains a clamping mechanism. The clamping seat has a locking slot, and the clamping mechanism is used to engage the side of the reinforcement cage body with the locking slot of the reinforcement cage body.

[0007] By adopting the above technical solution, when the lifting mechanism lifts, the clamping mechanism can clamp the side of the steel cage body, which facilitates the lifting of the steel cage body. During this process, there is no need for manual fixation of the slings, which reduces the possibility of unstable lifting due to manual fixation of the slings and improves the safety of the lifting.

[0008] Optionally, the lifting mechanism includes a crane, slings, and a lifting frame. The two ends of the lifting frame are respectively connected to the clamping mechanisms in the corresponding clamping seats. The lifting end of the crane is connected to one end of the slings, and the other end of the slings is connected to the frame of the lifting frame.

[0009] By adopting the above technical solution, when it is necessary to hoist the rebar cage body, the side of the rebar cage body is placed into the slots in the clamping seats, so that the four clamping seats are respectively located on the four lifting points of the rebar cage body, and the two lifting frames are connected to the rebar cage body in parallel and at intervals. The crane is started, and the lifting frames are hoisted by slings to raise the clamping seats. During this process, the lifting frames will be linked with the clamping mechanism, so that the clamping mechanism clamps the side of the rebar cage body. At this time, the rebar cage body can be hoisted without the need for construction personnel to manually fix the slings to the rebar cage body, which reduces the difficulty of operation and reduces the safety hazards of manual fixing.

[0010] Optionally, the clamping mechanism includes a clamping plate, a transmission assembly, and a one-way locking assembly. Two sets of clamping plates and transmission assemblies are provided respectively, and the two clamping plates are slidably installed on the two side walls of the clamping seat corresponding to the bayonet. A connecting rod that is fixedly connected to the clamping plate is slidably installed in the clamping seat. The connecting rod is located on the side away from the bayonet, and the end of the connecting rod away from the clamping plate is set as a wedge-shaped inclined surface. The transmission component can push the corresponding end of the connecting rod to move so that the two clamping plates slide towards each other. A first reset member is provided in the clamping seat for driving the clamping plates to move away from the bayonet.

[0011] By adopting the above technical solution, when the lifting frame rises, the lifting frame drives the one-way locking component to move. At this time, the one-way locking component is connected to the transmission component. The transmission component drives the two clamping plates to move towards each other, so that the upper and lower sides of the steel cage body can be clamped and fixed. At this time, the steel cage body can be hoisted.

[0012] Optionally, the transmission assembly includes a rotating column, a first transmission rod, and a second transmission rod. The rotating column is rotatably mounted in the clamping seat, and the first transmission rod and the second transmission rod are both slidably mounted in the clamping seat. A groove is provided on the peripheral wall of the rotating column corresponding to the end of the first transmission rod. The end of the first transmission rod is slidably installed in the groove and located at one end of the groove. The depth of the groove gradually decreases from the end near the first transmission rod to the end away from the first transmission rod. The end of the first transmission rod away from the rotating column is provided with a wedge-shaped inclined surface, and both ends of the second transmission rod are provided with wedge-shaped inclined surfaces. The two ends of the second transmission rod are close to the ends of the first transmission rod and the connecting rod, respectively. When the rotating column rotates, the end of the first transmission rod pushes against the second transmission rod, so that the second transmission rod drives the connecting rod to slide towards the bayonet.

[0013] By adopting the above technical solution, when the one-way locking assembly drives the rotating column to rotate, the rotating column drives the slide groove to rotate, causing the end of the first transmission rod to move along the slide groove. At this time, the first transmission rod moves away from the side wall of the rotating column. The end of the first transmission rod away from the rotating column pushes the end of the second transmission rod, causing the end of the second transmission rod away from the first transmission rod to drive the connecting rod to move. The connecting rod drives the clamping plate to move closer to the bayonet, so that the two clamping plates clamp and fix the upper and lower sides of the steel cage body.

[0014] Optionally, the one-way locking assembly includes an inner ratchet, a gear post, and a rack. One end of the inner ratchet is fixedly connected to the rotating post, and the other end is fixedly connected to the gear post. The rack is fixed to the end of the lifting frame, and the rack meshes with the gear post. When the lifting frame lifts the steel cage body, the inner ratchet rotates in one direction to clamp and fix the side of the steel cage body with the clamping plate.

[0015] By adopting the above technical solution, when the lifting frame lifts, the rack drives the gear column to rotate. The gear column, through an internal ratchet, drives the rotating column to rotate, thus clamping the rebar cage body with the clamping plate. When the rebar cage body is lifted to the predetermined height, a crane is controlled to continue lifting, causing the lifting frame to rotate from a position perpendicular to the rebar cage body to the same position, i.e., lifting the rebar cage body to a vertical position. During this process, the rack on the lifting frame drives the gear column to rotate in the opposite direction. Since the internal ratchet does not connect the gear column and the rotating column, this process has no impact on the clamping and fixing of the clamping plate. After the vertical lifting of the rebar cage body is completed, the rebar cage body is placed in the pre-excavated trench, and the lifting frame is lowered. At this point, without the lifting frame applying rotational force to the gear column, the clamping plate's clamping effect on the rebar cage body is weak, and the clamping seat automatically detaches from the side of the rebar cage body, thus completing the lifting process.

[0016] Optionally, the internal ratchet includes an inner disc, an outer disc, and a pawl. The inner disc is rotatably mounted inside the outer disc, and the pawl is rotatably mounted on the inner disc. The gear column is coaxially fixed with the inner disc, and the outer disc is coaxially fixed with the rotating column. When the lifting frame lifts, the gear column drives the outer disc to rotate through the inner disc, causing the rotating column to rotate.

[0017] By adopting the above technical solution, when the lifting frame lifts, the rack will drive the gear column to rotate, the gear column will drive the inner plate to rotate, the inner plate will drive the ratchet to rotate, the ratchet will be connected to the outer plate at this time, the ratchet will drive the outer plate to rotate, the outer plate will drive the rotating column to rotate, so that the two clamping plates clamp and fix the steel cage body.

[0018] Optionally, the end of the rack is configured as a hook.

[0019] By adopting the above technical solution, the hook-shaped end of the rack can keep the rack and gear column in a meshing state at all times, preventing the rack and gear column from separating during lifting and lowering.

[0020] Optionally, the clamping seat is provided with a second reset member for driving the first transmission rod to move closer to the side wall of the rotating column, and the clamping seat is provided with a third reset member for driving the second transmission rod to move away from the end of the connecting rod.

[0021] By adopting the above technical solution, the second and third reset components will drive the first and second transmission rods to reset, thereby reducing the influence of the first and second transmission rods on the connecting rod.

[0022] Optionally, the clamping seat is provided with a fourth reset element for driving the rotating column to rotate and reset.

[0023] By adopting the above technical solution, after the hoisting of the steel cage body is completed, the lower lifting frame will not be connected to the gear column and the rotating column during the process. Under the action of the fourth reset component, the rotating column will rotate to the initial position. With the cooperation of the first reset component, the second reset component and the third reset component, the clamping plate will no longer abut against the two sides of the steel cage body. At this time, the clamping seat will directly detach from the steel cage body, and the disassembly of the lifting frame can be completed quickly.

[0024] This application also provides a method for the overall hoisting construction of reinforcement cages for ultra-deep underground continuous walls, used in the aforementioned overall hoisting device for reinforcement cages for ultra-deep underground continuous walls, including the following steps: S1: Secure each clamping seat to the side of the steel cage; S2: Turn on the crane so that the slings can lift the lifting frame until the steel cage is lifted horizontally to the set height; S3: Control the retraction of the sling of one of the cranes until the steel cage rotates from a horizontal position to a vertical position; S4: Control the crane to lift the steel cage into the pre-excavated trench, and then lower the slings to complete the lifting.

[0025] In summary, this application includes at least the following beneficial technical effects: When hoisting the rebar cage, place the side of the rebar cage into the slots of the clamping seats, positioning the four clamping seats at the four lifting points of the rebar cage. Connect the two lifting frames parallel and spaced apart to the rebar cage. Start the crane and use slings to lift the lifting frames, raising the clamping seats. During this process, the lifting frames will engage the clamping mechanism, clamping the side of the rebar cage. The rebar cage can then be hoisted without requiring manual fixing of the slings to the cage, reducing operational difficulty and safety hazards associated with manual fixing. When the steel cage body is hoisted to the predetermined height, a crane is controlled to continue hoisting, so that the hoisting frame rotates from a state perpendicular to the steel cage body to the same state as the steel cage body, that is, the steel cage body is hoisted to a vertical state. During this process, the rack on the hoisting frame drives the gear column to rotate in the opposite direction. At this time, the internal ratchet does not connect the gear column and the rotating column, so this process has no effect on the clamping and fixing of the clamping plate. After the vertical hoisting of the steel cage body is completed, the steel cage body is placed in the pre-excavated trench, and the hoisting frame is lowered. At this time, the hoisting frame does not exert a rotational force on the gear column, and the clamping plate has a weak clamping effect on the steel cage body. The clamping seat automatically detaches from the side of the steel cage body, thus completing the hoisting process. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail below.

[0030] This application discloses an integral hoisting device for the steel cage of an ultra-deep underground continuous wall.

[0031] A hoisting device for the integral lifting of steel cages for ultra-deep underground continuous wall is used to lift the steel cage body 4, as shown in the reference. Figure 1 and Figure 2 It includes a clamping seat 1, a clamping mechanism 3 disposed in the clamping seat 1, and a lifting mechanism 2 for lifting the clamping seat 1. The clamping seat 1 is provided with two sets corresponding to the two sides of the steel cage body 4. Each set of clamping seats 1 is provided with a clamping mechanism 3. The clamping seat 1 is provided with a slot 11. The clamping mechanism 3 is used to clamp the side of the steel cage body 4 into the slot 11 of the steel cage body 4.

[0032] In this embodiment, the lifting mechanism 2 is provided in two sets. The two sets of lifting mechanisms 2 can lift the head and tail of the steel cage body 4. There are four lifting points. The four lifting points are evenly located on the two sides of the steel cage body 4. The line connecting the four lifting points is a rectangle. Each lifting point has a corresponding clamping seat 1, that is, there are four clamping seats 1. Reference Figure 1 and Figure 2 The lifting mechanism 2 includes a crane, a sling 21, and a lifting frame 22. The two ends of the lifting frame 22 are respectively connected to the clamping mechanism 3 in the corresponding clamping seat 1. The lifting end of the crane is connected to one end of the sling 21, and the other end of the sling 21 is fixedly connected to the middle of the frame of the lifting frame 22.

[0033] When it is necessary to hoist the steel cage body 4, place the side of the steel cage body 4 into the slot 11 inside the clamping seat 1, so that the four clamping seats 1 are respectively located on the four lifting points of the steel cage body 4, and connect the two lifting frames 22 parallel and spaced to the steel cage body 4. Start the crane and hoist the lifting frame 22 through the sling 21 to raise the clamping seat 1. During this process, the lifting frame 22 will be linked with the clamping mechanism 3, so that the clamping mechanism 3 clamps the side of the steel cage body 4, and the steel cage body 4 can then be hoisted. Specifically, refer to Figure 2 , Figure 3 and Figure 4 The clamping mechanism 3 includes a clamping plate 31, a transmission component 32, and a one-way locking component 33. Two sets of clamping plates 31 and transmission components 32 are provided respectively. The two clamping plates 31 are slidably installed on the two side walls of the clamping seat 1 corresponding to the bayonet 11.

[0034] A connecting rod 12, which is fixedly connected to the clamping plate 31, is slidably installed in the clamping base 1. The connecting rod 12 is located on the side away from the bayonet 11, and the end of the connecting rod 12 away from the clamping plate 31 is set as a wedge-shaped inclined surface. The transmission component 32 can push the corresponding end of the connecting rod 12 to move so that the two clamping plates 31 slide in a direction closer to each other. A first reset member 121 is provided in the clamping base 1 for driving the clamping plate 31 to move away from the bayonet 11.

[0035] Reference Figure 3 and Figure 4 The transmission assembly 32 includes a rotating column 321, a first transmission rod 322 and a second transmission rod 323. The rotating column 321 is rotatably mounted in the clamping seat 1, and the first transmission rod 322 and the second transmission rod 323 are both slidably mounted in the clamping seat 1. A groove 3211 is provided on the peripheral wall of the rotating column 321 corresponding to the end of the first transmission rod 322. The end of the first transmission rod 322 is slidably installed in the groove 3211 and located at one end of the groove 3211. The groove depth of the groove 3211 gradually becomes shallower from the end near the first transmission rod 322 to the end away from the first transmission rod 322. The end of the first transmission rod 322 away from the rotating column 321 is set as a wedge-shaped inclined surface, and both ends of the second transmission rod 323 are set as wedge-shaped inclined surfaces. The two ends of the second transmission rod 323 are close to the ends of the first transmission rod 322 and the connecting rod 12, respectively. When the rotating column 321 rotates, the end of the first transmission rod 322 pushes against the second transmission rod 323, so that the second transmission rod 323 drives the connecting rod 12 to slide towards the bayonet 11.

[0036] Reference Figure 3 and Figure 4The one-way locking assembly 33 includes an inner ratchet 331, a gear post 332, and a rack 333. One end of the inner ratchet 331 is fixedly connected to the rotating post 321, and the other end is fixedly connected to the gear post 332. The rack 333 is fixed to the end of the lifting frame 22 and meshes with the gear post 332. The end of the rack 333 is configured as a hook. When the lifting frame 22 lifts the steel cage body 4, the inner ratchet 331 rotates in one direction to clamp and fix the side of the steel cage body 4 with the clamping plate 31.

[0037] The internal ratchet 331 includes an inner disc 3311, an outer disc 3312, and a pawl 3313, as shown in the reference. Figure 3 and Figure 4 The inner disk 3311 is rotatably mounted inside the outer disk 3312, the pawl 3313 is rotatably mounted on the inner disk 3311, the gear column 332 is coaxially fixed with the inner disk 3311, and the outer disk 3312 is coaxially fixed with the rotating column 321. When the lifting frame 22 lifts, the gear column 332 drives the outer disk 3312 to rotate through the inner disk 3311, causing the rotating column 321 to rotate.

[0038] Reference Figure 3 and Figure 4 A second reset member 3221 is sleeved on the first transmission rod 322. The second reset member 3221 can drive the first transmission rod 322 to move closer to the side wall of the rotating column 321. A third reset member 3231 is sleeved on the second transmission rod 323. The third reset member 3231 can drive the second transmission rod 323 to move away from the end of the connecting rod 12. Both the second reset member 3221 and the third reset member 3231 are springs. The second reset member 3221 and the third reset member 3231 will drive the rod bodies of the first transmission rod 322 and the second transmission rod 323 to reset, thereby reducing the influence of the first transmission rod 322 and the second transmission rod 323 on the connecting rod 12.

[0039] Furthermore, a fourth reset component is fitted onto the rotating column 321. The fourth reset component can drive the rotating column 321 to rotate and reset. The fourth reset component is a torsion spring. After the hoisting of the steel cage body 4 is completed, the lower lifting frame 22 is in operation. During this process, the gear column 332 and the rotating column 321 are not connected by transmission. Under the action of the fourth reset component, the rotating column 321 will rotate to the initial position. With the cooperation of the first reset component 121, the second reset component 3221 and the third reset component 3231, the clamping plate 31 no longer abuts and fixes against both sides of the steel cage body 4. At this time, the clamping seat 1 will directly detach from the steel cage body 4, and the disassembly of the lifting frame 22 can be completed quickly.

[0040] The implementation principle of the overall hoisting device for ultra-deep underground continuous wall reinforcement cages in this application embodiment is as follows: When it is necessary to hoist the reinforcement cage body 4, the side of the reinforcement cage body 4 is placed into the slot 11 in the clamping seat 1, so that the four clamping seats 1 are respectively located on the four lifting points of the reinforcement cage body 4, and the two lifting frames 22 are connected to the reinforcement cage body 4 in parallel and at intervals. The crane is started, and the lifting frame 22 is hoisted by the sling 21, so as to raise the clamping seat 1. During this process, the lifting frame 22 will be linked with the clamping mechanism 3, so that the clamping mechanism 3 clamps the side of the reinforcement cage body 4, and the reinforcement cage body 4 can be hoisted at this time.

[0041] When the steel cage body 4 is hoisted to the predetermined height, a crane is controlled to continue hoisting, so that the hoisting frame 22 rotates from a state perpendicular to the steel cage body 4 to the same state as the steel cage body 4, that is, the steel cage body 4 is hoisted to a vertical state. During this process, the rack 333 on the hoisting frame 22 drives the gear column 332 to rotate in the opposite direction. At this time, the inner ratchet 331 does not connect the gear column 332 and the rotating column 321. Therefore, this process has no effect on the clamping and fixing of the clamping plate 31.

[0042] After the vertical hoisting of the steel cage body 4 is completed, the steel cage body 4 is placed in the pre-excavated trench, and the hoisting frame 22 is lowered. At this time, the hoisting frame 22 does not exert a rotational force on the gear column 332. At this time, the clamping effect of the clamping plate 31 on the steel cage body 4 is not strong, and the clamping seat 1 automatically falls off from the side of the steel cage body 4, thus realizing the hoisting process.

[0043] This application also discloses a method for the overall hoisting construction of a steel cage for an ultra-deep underground continuous wall, used for the construction of the steel cage body 4 by the aforementioned overall hoisting device for the steel cage of an ultra-deep underground continuous wall, including the following steps: S1: Secure the latches 11 of each clamping seat 1 to the side of the steel cage respectively; S2: Turn on the crane so that the sling 21 drives the lifting frame 22 to lift the steel cage until it is horizontally lifted to the set height; S3: Control the retraction of the sling 21 of one of the cranes until the steel cage rotates from a horizontal state to a vertical state; S4: Control the crane to lift the steel cage into the pre-excavated trench, and lower the sling 21 to complete the lifting.
