Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for the construction of anti-seepage walls, specifically, it is a collision-resistant anti-seepage wall steel cage hoisting device. Background Technology

[0002] Reinforced concrete bored piles are widely used in industrial and civil buildings, railways, and highways. Lowering the reinforcing cage into the borehole is a crucial step in the construction of bored piles. Currently, commonly used reinforcing cage hoisting devices present the following problems during the hoisting process: First, the reinforcing cage can easily twist during hoisting due to entanglement with external objects. Second, soft hoisting ropes can cause the reinforcing cage to sway and collide with external objects during hoisting and displacement. Third, wind and other factors can cause the reinforcing cage to sway during lowering, affecting its accurate placement.

[0003] Therefore, it is necessary to design a steel cage hoisting device to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a collision-proof and seepage-proof wall steel cage hoisting device to solve the problems of existing steel cage hoisting devices, which are prone to causing steel cage swaying during hoisting and swaying in a small space during lowering, and the difficulty in accurately controlling the lowering speed.

[0005] To solve the above problems, the present invention adopts the following technical means:

[0006] A hoisting device for a steel cage for an anti-collision and seepage-proof wall includes a support plate. A threaded rod with a vertical rotation axis is slidably mounted on the support plate. A bearing platform is mounted at the bottom end of the threaded rod. A limit rod is mounted on the top surface of the bearing platform. The limit rod is parallel to the threaded rod and slides through the support plate. A hook mechanism is mounted on the bottom surface of the bearing platform. A drive mechanism for driving the threaded rod to move linearly is mounted on the top surface of the support plate.

[0007] Preferably, a lifting mechanism is installed on both sides of the threaded rod on the support plate. The lifting mechanism includes a first take-up machine installed on the support plate and a support frame located on both sides of the threaded rod. The top end of the support frame extends upward and is located on the upper plane of the threaded rod. A fixed pulley is rotatably installed on the top end of the support frame. A steel wire is rotatably connected to the top end of the threaded rod. The steel wire passes around the top end of the fixed pulley and extends into the first take-up machine and connects with its take-up mechanism.

[0008] Furthermore, a connecting block is coaxially rotatably mounted on the top end of the threaded rod, the steel wire is fixedly connected to the top surface of the connecting block, and the portion of the steel wire located between the threaded rod and the fixed pulley is vertically arranged.

[0009] Furthermore, the driving mechanism includes a driving disk sleeved on the threaded rod and rotatably mounted on the top surface of the support plate. The driving disk is threadedly connected to the threaded rod. The top surface of the driving disk is constructed as a bevel gear structure. The driving mechanism also includes a first rotating motor. The rotating end of the first rotating motor is meshed with the bevel gear structure on the top surface of the driving disk through a first bevel gear. The driving disk is vertically positioned and connected to the support plate.

[0010] Furthermore, the hook mechanism includes a clamping rod arranged around the axis of the support platform, and a hanging plate is installed on the bottom side of the clamping rod facing the axis of the support platform, with the top surface of the hanging plate being horizontally arranged.

[0011] Furthermore, the bottom surface of the support platform is constructed with a radially extending displacement groove around its axis. The top end of the clamping rod is slidably installed in the displacement groove, and the top end of the clamping rod is slidably connected to the displacement groove through a slider-groove mechanism. A circular cavity is coaxially provided inside the support platform, and a take-up reel is coaxially provided inside the circular cavity. A rotating rod is coaxially installed on the bottom surface of the axial reel. The rotating rod rotatably extends out of the circular cavity and is coaxially connected to the rotating end of the second rotating motor. Several pull wires are wound around the outer edge of the take-up reel. Each pull wire extends horizontally out of the circular cavity and into the displacement groove, connecting to the top side of the clamping rod. A compression spring is installed inside the displacement groove, and the two ends of the compression spring abut against the side of the clamping rod facing the circular cavity and the side of the displacement groove facing the circular cavity, respectively.

[0012] This utility model has the following beneficial effects during use:

[0013] When hoisting a reinforcing cage, a hook mechanism is used to clamp and position the cage. Then, a drive mechanism moves a threaded rod vertically up and down along its axis, lifting and lowering the cage. The rigidity of the threaded rod effectively prevents swaying due to external factors during lifting and lowering, thus improving the cage's stability. Furthermore, the up-and-down movement of the threaded rod, driven by the drive mechanism, utilizes the characteristics of the threaded connection to ensure a more accurate and uniform descent of the cage at a low speed during lowering. This contributes to the accurate assembly and stability of the reinforcing cage. Attached Figure Description

[0024] Please refer to Figures 1 to 3 As shown, a hoisting device for a collision-resistant and seepage-proof wall steel cage includes a support plate 1. A threaded rod 2 with a vertical rotation axis is slidably mounted on the support plate 1. A bearing platform 3 is mounted at the bottom end of the threaded rod 2, and the bearing platform 3 is coaxially connected to the threaded rod 2. A limiting rod 4 is mounted on the top surface of the bearing platform 3, and the limiting rod 4 is arranged parallel to the threaded rod 2. The limiting rod 4 slides through the support plate 1. A hook mechanism is mounted on the bottom surface of the bearing platform 3, and a driving mechanism for driving the threaded rod 2 to move linearly is mounted on the top surface of the support plate 1.

[0025] In this way, when hoisting the rebar cage, after the hook mechanism clamps and positions the cage, the drive mechanism moves the threaded rod 2 vertically up and down along its axis, thereby lifting and lowering the cage held by the hook mechanism. The rigidity of the threaded rod 2 effectively prevents the cage from swaying due to external factors during lifting and lowering, thus improving the stability of the cage during hoisting. Furthermore, by using the up-and-down movement of the threaded rod 2, the drive mechanism, utilizing the characteristics of the threaded connection, allows for a more accurate and uniform descent of the cage at a low speed during lowering. This is beneficial for the accurate assembly and stability of the rebar cage.

[0026] Furthermore, a lifting mechanism is installed on both sides of the threaded rod 2 on the support plate 1. The lifting mechanism includes a first take-up machine 5 installed on the support plate 1 and a support frame 6 located on both sides of the threaded rod 2. The top end of the support frame 6 extends upward and is located on the upper plane of the threaded rod 2. A fixed pulley 7 is rotatably installed on the top end of the support frame 6. A steel wire 8 is rotatably connected to the top end of the threaded rod 2. The steel wire 8 passes around the top end of the fixed pulley 7 and extends into the first take-up machine 5 to connect with its take-up mechanism.

[0027] In this way, by using the lifting mechanism, the impact of the large downward force on the threaded rod 2 due to the weight of the reinforcing cage can be effectively reduced during the up-and-down movement of the threaded rod 2 driven by the drive mechanism. This avoids excessive downward force in the vertical direction on the threaded rod 2, which could cause the threaded connection structure to be squeezed and affect the normal up-and-down movement of the threaded rod 2.

[0028] Furthermore, a connecting block 9 is coaxially rotatably mounted on the top of the threaded rod 2, and the steel wire 8 is fixedly connected to the top surface of the connecting block. The portion of the steel wire 8 located between the threaded rod 2 and the fixed pulley 7 is vertically arranged.

[0029] In this way, not only can the steel wire 8 be used to apply a vertical upward pulling force to the threaded rod 2, but the connection block 9 can also effectively prevent the steel wire 8 from getting tangled when the threaded rod 2 rotates unexpectedly.

[0030] Furthermore, the driving mechanism includes a driving disk 10 sleeved on the threaded rod 2 and rotatably mounted on the top surface of the support plate 1. The driving disk 10 is threadedly connected to the threaded rod 2. The top surface of the driving disk 10 is constructed as a bevel gear structure. The driving mechanism also includes a first rotating motor 11. The rotating end of the first rotating motor 11 is meshed with the bevel gear structure on the top surface of the driving disk 10 through a first bevel gear 12. The driving disk 10 is vertically positioned and connected to the support plate 1.

[0031] In this way, the first rotating motor 11 of the drive mechanism can rotate the drive disk 10. When the drive disk 10 rotates and is vertically positioned and connected to the support plate 1, the threaded rod 2, which is threadedly connected to the drive disk 10, can move up and down, thereby completing the hoisting of the steel cage.

[0032] Furthermore, the hook mechanism includes a clamping rod 13 arranged around the axis of the support platform 3, and a hanging plate 14 is installed on the bottom side of the clamping rod 13 facing the axis of the support platform 3, and the top surface of the hanging plate 14 is horizontally arranged.

[0033] In this way, by using the horizontally set hanging plate 14 on the top surface, it is possible to avoid the hanging plate 14 getting stuck with the steel bars of the steel cage during the assembly process, which would affect the installation of the hanging plate 14.

[0034] Furthermore, regarding the installation process of the hanging plate 14, in order to facilitate installation and enable hoisting of steel cages of different diameters, the bottom surface of the support platform 3 is constructed with a radially extending displacement groove 15 around its axis. The top end of the clamping rod 13 is slidably installed in the displacement groove 15, and the top end of the clamping rod 13 is slidably connected to the displacement groove 15 through a slider-sliding mechanism. A circular cavity 16 is coaxially provided inside the support platform 3, and a take-up reel 17 is coaxially provided inside the circular cavity 16. The bottom surface of the take-up reel is coaxially mounted with... The device is equipped with a rotating rod that extends out of the circular cavity 16 and is coaxially connected to the rotating end of the second rotating motor 18. The outer edge of the take-up reel 17 is wound with several pull wires 19. Each pull wire 19 extends horizontally out of the circular cavity 16 and enters the displacement groove 15 to connect with the top side of the clamping rod 13. A compression spring 20 is installed in the displacement groove 15. The two ends of the compression spring 20 abut against the side of the clamping rod 13 facing the circular cavity 16 and the side of the displacement groove 15 facing the circular cavity 16, respectively.

[0035] In this way, the winding of the pull wire 19 can be achieved by controlling the rotation of the second rotary motor 18. When the pull wire 19 is wound, the clamping rod 13 moves towards the circular cavity 16, and the compression spring 20 is continuously compressed. When the pull wire 19 is unwound, the clamping rod 13 moves away from the cylindrical cavity under the action of the compression spring 20. Moreover, with the structural arrangement in this embodiment, all the clamping rods 13 can be driven to move towards or away from the circular cavity 16 simultaneously, thereby achieving the clamping and releasing of the steel cage held between the clamping rods 13.

[0036] Furthermore, for ease of movement, at least three support rods 21 are installed on the bottom surface of the support plate 1, and a displacement mechanism is installed at the bottom end of each support rod 21.

[0037] The displacement mechanism here can be a lockable caster wheel or an electric wheel.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
