Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a hoisting and guiding mechanism for pile foundation steel cages. Background Technology

[0002] A pile foundation is a deep foundation consisting of piles and a pile cap connecting the tops of the piles. A pile foundation comprises two parts: piles and a pile cap. A pile is a vertical or inclined column-shaped foundation member with a certain rigidity and bending resistance, set in the soil; its cross-sectional dimension is much smaller than its length. The pile cap connects the tops of several piles into a whole, transferring and distributing the load from the superstructure to each pile.

[0003] When placing, handling, and hoisting the steel reinforcement cage, deformation should be prevented. When placing it, it should be aligned with the hole position to avoid collision with the hole wall.

[0004] There is an existing patent application with application number 202322317430.3 entitled "A Lifting and Fixing Platform for Large-Diameter Cast-in-Place Pile Heavy Reinforcing Cages," which includes a lifting ring for assisting in the lifting, placement, and fixing of the reinforcing cage, and a positioning structure for positioning and supporting the reinforcing cage; the positioning structure is fixedly connected to the lower part of the lifting ring. The lifting ring includes a steel ring, an inner lifting plate fixedly disposed inside the steel ring, an outer lifting plate fixedly disposed outside the steel ring, and a sleeve; the upper and lower end faces of the steel ring are provided with several through holes, and the outer ends of the through holes are fixedly provided with gaskets and sleeves.

[0005] However, the above solutions have the following problems: 1. The existing steel cages are all placed by directly lifting them into the hole by a crane, which cannot prevent the steel cages from shaking during hoisting and is prone to colliding with the hole wall. 2. There are many support points for supporting the steel cages, which need to be extended one by one, making the operation inconvenient. Utility Model Content

[0006] The purpose of this utility model is to solve the above problems and provide a hoisting guide mechanism for pile foundation steel cages, which prevents damage to the borehole wall during hoisting of the steel cages and facilitates the support of the steel cages.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A pile foundation reinforcement cage hoisting guide mechanism includes a base, support rods mounted on the base and movable on the base for supporting the reinforcement cage, rollers that cooperate with the reinforcement cage symmetrically provided on the base, grooves that cooperate with the reinforcement cage provided on the outer cylindrical surface of the rollers, and a drive mechanism provided on the base for driving several of the support rods to extend and retract synchronously.

[0009] Furthermore, the base is provided with a bracket for supporting the roller.

[0010] Furthermore, the driving mechanism includes a rotating ring disposed on the base and rotating on the base. The base has a first elongated hole at a position corresponding to the support rod, and the rotating ring has a second elongated hole at a position corresponding to the support rod. The support rod has a guide rod that passes through the first elongated hole and the second elongated hole in sequence. The second elongated hole is inclined outward in a clockwise direction.

[0011] Furthermore, the base is provided with a plurality of support wheels that cooperate with the inner wall of the rotating ring evenly along the circumference of the rotating ring.

[0012] Furthermore, a handle is provided on the outer cylindrical surface of the rotating ring.

[0013] Furthermore, the length direction of the first elongated hole is parallel to the length direction of the support rod.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model includes a base and a support rod for supporting a reinforcing cage, which is mounted on the base and moves on the base. The base is symmetrically provided with rollers that cooperate with the reinforcing cage. The outer cylindrical surface of the rollers is provided with grooves that cooperate with the reinforcing cage. The symmetrically arranged rollers contact the reinforcing cage and the grooves position the reinforcing cage to prevent the reinforcing cage from shaking and damaging the hole wall when it is hoisted.

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] like Figure 1 As shown, a pile foundation reinforcement cage hoisting guide mechanism includes a base 1 and support rods 2 mounted on the base 1 and movable on the base 1 for supporting the reinforcement cage. In this embodiment, the base 1 is a rectangular base, and four support rods 2 are provided. The four support rods 2 pass through the four sides of the base 1 and are slidably connected to the base 1. The base 1 is symmetrically provided with rollers 3 that cooperate with the reinforcement cage. The outer cylindrical surface of the rollers 3 is provided with grooves that cooperate with the reinforcement cage. The symmetrically arranged rollers contact the reinforcement cage, and the grooves position the reinforcement cage to prevent the reinforcement cage from shaking and damaging the borehole wall during hoisting. The base 1 is provided with a drive mechanism for driving the several support rods 2 to extend and retract synchronously.

[0022] like Figure 1 As shown, the base 1 is provided with a bracket 4 for supporting the roller 3.

[0023] like Figure 1 and Figure 2 As shown, the driving mechanism includes a rotating ring 5 mounted on and rotating on the base 1. A first elongated hole 6 is provided on the base 1 at a position corresponding to the support rod 2. A second elongated hole 7 is provided on the rotating ring 5 at a position corresponding to the support rod 2. A guide rod 8 is provided on the support rod 2, passing sequentially through the first elongated hole 6 and the second elongated hole 7. The second elongated hole 7 is inclined outwards in a clockwise direction. When the rotating ring 5 rotates clockwise, the support rod 2 moves inwards under the action of the second elongated hole 7 and the guide rod 8, supporting the reinforcing cage. When the rotating ring 5 rotates counterclockwise, the support rod 2 moves outwards under the action of the second elongated hole 7 and the guide rod 8, facilitating the hoisting of the next reinforcing cage. It eliminates the need to move each support rod 2 individually, making operation convenient.

[0024] like Figure 1 and Figure 2 As shown, the base 1 is evenly provided with a plurality of support wheels 9 along the circumference of the rotating ring 5, which cooperate with the inner wall of the rotating ring 5. In this embodiment, there are four support wheels 9. The inner wall of the rotating ring 5 is supported by the support wheels 9, thereby realizing the positioning of the rotating ring 5 and preventing the rotating ring 5 from shifting.

[0025] like Figure 1 and Figure 2As shown, a handle 10 is provided on the outer cylindrical surface of the rotating ring 5, which is held by a person to facilitate the rotation of the rotating ring 5.

[0026] The length direction of the first elongated hole 6 is parallel to the length direction of the support rod 2.
