Technical Field
[0001] This utility model relates to the field of hoisting tools, specifically to a hoisting tool for ultra-deep drilling and grouting of steel cages. Background Technology
[0002] Drilled cast-in-place piles are an important construction method for engineering foundation structures, widely used in building construction, bridge foundations, and other projects. They are characterized by simple construction techniques and low operational difficulty. In the construction of drilled cast-in-place piles, multiple lifting bars are first welded to the top of a precast reinforcing cage. To facilitate hoisting the cage, the ends of these lifting bars furthest from the cage are made into loops. The distance between the loop of the lifting bar and the top of the reinforcing cage is equal to the designed depth of the cage in the pile hole. The cage is lowered into the pile hole, and a spreader beam is passed through the loop ends of the lifting bars. The spreader beam is then placed on the ground around the pile hole, allowing the cage to reach the designed depth. Concrete can then be poured into the pile hole, and once the concrete has set, the construction of the cast-in-place pile is complete.
[0003] When placing the existing rebar cage into the pile hole, hoisting tools are required. However, existing hoisting tools can only hoist the rebar cage individually and cannot help keep the rebar cage centered in the pile hole while hoisting it. As a result, the rebar cage is prone to tilting, which affects the subsequent concrete pouring. Therefore, a rebar cage hoisting tool for ultra-deep drilling and grouting is needed to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a rebar cage hoisting tool for ultra-deep drilling and grouting, which solves the problem that existing hoisting tools can only hoist the rebar cage, and it is difficult to keep the rebar cage centered in the pile hole while hoisting it. As a result, the rebar cage is prone to tilting, which affects the subsequent concrete pouring.
[0005] This utility model provides the following technical solution: a rebar cage hoisting tool for ultra-deep drilling and grouting, including a hoist, a hoisting plate fixedly connected to the top of the hoist, a hoisting machine connected to the outside of the hoisting plate, a straight groove opened at the bottom of the hoist, a rotating component inside the straight groove, two sets of translation components at the outer end of the rotating component, a fixing component at the side end of each set of translation components, and a pressing component at the side end of each set of translation components to assist the rebar cage in centering within the pile hole.
[0006] As a preferred embodiment of the above technical solution, the rotating assembly includes a motor, which is fixedly installed on the outer side of the hanger. A bidirectional threaded rod is installed at the output end of the motor. The bidirectional threaded rod is rotatably disposed between the left and right sides inside the straight groove. A guide rod is fixedly connected between the left and right sides inside the straight groove.
[0007] As a preferred embodiment of the above technical solution, the translation component includes a threaded sleeve, which is threadedly connected to the outer end of a bidirectional threaded rod. The top side end of the threaded sleeve is fitted onto the outer end of a guide rod. A movable plate is fixedly connected to the bottom end of the threaded sleeve. A vertical groove is provided on the side end of the movable plate. An extension plate is fixedly connected to the side end of the movable plate.
[0008] As a preferred embodiment of the above technical solution, the fixing component includes a screw rod, which is rotatably disposed between the top and bottom ends of the vertical groove. A rotating plate is fixedly connected to the top outer end of the screw rod, and a sleeve plate is threadedly connected to the outer end of the screw rod. A limit plate is fixedly connected to the side end of the sleeve plate, and an L-shaped fixing plate is fixedly connected to the side end of the sleeve plate.
[0009] As a preferred embodiment of the above technical solution, the pressing component includes a hollow rod, which is fixedly connected to the side end of the movable plate. A spring is fixedly connected to the inner side end of the hollow rod, a circular plate is fixedly connected to the side end of the spring, and a circular rod is fixedly connected to the side end of the circular plate.
[0010] As a preferred embodiment of the above technical solution, a ball groove box is fixedly connected to the side end of the round rod, and ball bearings are installed inside the ball groove box.
[0011] As a preferred embodiment of the above technical solution, a steel cage is installed between the interiors of the two sets of fixing components.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention uses a rotating component to drive two sets of translation components toward the side of the rebar cage. Two sets of fixing components can fix the rebar cage between the two sets of translation components. When the crane lifts the frame and the rebar cage into the pile hole, the pressing component can help place the rebar cage in the center of the pile hole, making it less likely for the rebar cage to tilt and avoiding affecting the subsequent concrete pouring.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a rebar cage hoisting tool for ultra-deep drilling and grouting, including a hoist 1, a hoisting plate 102 fixedly connected to the top of the hoist 1, a hoisting machine connected to the outside of the hoisting plate 102, a straight groove 101 opened at the bottom of the hoist 1, a rotating component 2 provided inside the straight groove 101, two sets of translation components 3 provided at the outer end of the rotating component 2, a fixing component 4 provided at the side end of each set of translation components 3, a rebar cage 6 installed between the two sets of fixing components 4, and a pressing component 5 provided at the side end of each set of translation components 3 to assist the rebar cage 6 in centering in the pile hole. The rotating component 2 drives the two sets of translation components 3 to move closer to the side end of the rebar cage 6, and the two sets of fixing components 4 can fix the rebar cage 6 between the two sets of translation components 3. When the hoisting machine lifts the hoist 1 and the rebar cage 6 into the pile hole, the pressing component 5 can assist the rebar cage 6 in being placed in the center of the pile hole, so that the rebar cage 6 is not prone to tilting, thus avoiding affecting the subsequent concrete pouring.
[0021] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the rotating assembly 2 includes a motor 201, which is fixedly mounted on the outer side of the hanger 1. A bidirectional threaded rod 202 is mounted on the output end of the motor 201. The bidirectional threaded rod 202 is rotatably positioned between the left and right sides inside the straight groove 101. A guide rod 203 is fixedly connected between the left and right sides inside the straight groove 101. The translation assembly 3 includes a threaded sleeve 301, which is threadedly connected to the outer end of the bidirectional threaded rod 202. The top side of the threaded sleeve 301 is fitted onto the outer end of the guide rod 203. A movable [device / mechanism] is fixedly connected to the bottom end of the threaded sleeve 301. The movable plate 302 has a vertical groove 303 on its side end, and an extension plate 304 is fixedly connected to the side end of the movable plate 302. In practice, the bidirectional threaded rod 202 can be rotated by starting the motor 201. At this time, due to the limit of the guide rod 203 on the two sets of threaded sleeves 301, the bidirectional threaded rod 202 can drive the two sets of threaded sleeves 301 and the two sets of movable plates 302 to move closer to each other after rotating. At this time, the two sets of movable plates 302 move closer to the side end of the steel cage 6, and each extension plate 304 can be driven to pass through the steel cage 6, which is convenient for fixing the steel cage 6 with the fixing component 4.
[0022] As one implementation method in this embodiment, such as Figure 2 and Figure 4 As shown, the fixing component 4 includes a screw 401, which is rotatably disposed between the top and bottom ends of the vertical groove 303. A rotating plate 402 is fixedly connected to the top outer end of the screw 401, and a sleeve plate 403 is threadedly connected to the outer end of the screw 401. A limiting plate 404 is fixedly connected to the side end of the sleeve plate 403, and an L-shaped fixing plate 405 is fixedly connected to the side end of the sleeve plate 403. In practice, rotating the rotating plate 402 can drive the screw 401 to rotate. Since the limiting plate 404 is limited to the side end of the moving plate 302, the sleeve plate 403 can move downward at the outer end of the screw 401. The downward movement of the sleeve plate 403 drives the fixing plate 405 to move downward. The downward movement of the fixing plate 405 cooperates with the extension plate 304 to facilitate the clamping and fixing of the reinforcing cage 6. At this time, the hanging plate 102 is lifted by an external crane, which can drive the hanger 1 and the reinforcing cage 6 to move to the top of the pile hole.
[0023] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the pressing component 5 includes a hollow rod 501, which is fixedly connected to the side end of the movable plate 302. A spring 502 is fixedly connected to the inner side end of the hollow rod 501, a circular plate 503 is fixedly connected to the side end of the spring 502, a circular rod 504 is fixedly connected to the side end of the circular plate 503, and a ball groove box 505 is fixedly connected to the side end of the circular rod 504. A ball bearing 506 is installed inside the ball groove box 505. In practice, after the reinforcing cage 6 is placed into the pile hole, the ball bearing 506 contacts the inner wall of the pile hole and rolls in the ball groove box 505. After the reinforcing cage 6 is placed, the springs 502 at both ends push against the circular plate 503, causing the circular rod 504 and the ball bearing 506 to press against the inner wall of the pile hole. At this time, it can help the reinforcing cage 6 to be placed in the center of the pile hole, so that the reinforcing cage 6 is not prone to tilting and avoids affecting the subsequent concrete pouring.
[0024] Working principle: Starting the motor 201 drives the bidirectional threaded rod 202 to rotate. Due to the guide rod 203 limiting the two sets of threaded sleeves 301, the rotation of the bidirectional threaded rod 202 causes the two sets of threaded sleeves 301 and the two sets of moving plates 302 to move closer together. The two sets of moving plates 302 then move towards the side of the reinforcing cage 6, allowing each extension plate 304 to pass through the reinforcing cage 6. Next, rotating the rotating plate 402 drives the screw 401 to rotate. Since the limiting plate 404 is positioned at the side of the moving plate 302, the sleeve plate 403 can move downwards at the outer end of the screw 401. The downward movement of the sleeve plate 403 causes the fixing plate 405 to move downwards. The fixing plate 405, in conjunction with the extension plate 304, facilitates the clamping and fixing of the reinforcing cage 6. At this point, an external crane lifts the lifting plate 102, moving the hanger 1 and the reinforcing cage 6 to the top of the pile hole. After the reinforcing cage 6 is placed into the pile hole, the ball bearing 506 rolls in the ball groove box 505 in contact with the inner wall of the pile hole. After the reinforcing cage 6 is placed, the springs 502 at both ends push against the circular plate 503, which drives the circular rod 504 and the ball bearing 506 to press against the inner wall of the pile hole. At this time, it can help the reinforcing cage 6 to be placed in the center of the pile hole, so that the reinforcing cage 6 is not easy to be skewed, thus avoiding affecting the subsequent concrete pouring. Subsequently, by rotating the rotating plate 402, the fixed plate 405 is moved upward, so that the fixed plate 405 no longer clamps the reinforcing cage 6. At this time, the motor 201 drives the bidirectional threaded rod 202 to rotate, which drives the two sets of moving plates 302 to open and move away. At this time, the moving plate 302 presses against the inner wall of the pile hole, and the spring 502 can be compressed and retracted. At this time, the crane equipment drives the lifting frame 1 to move upward, and the moving plate 302 can be moved out of the pile hole.
[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
