Description

Technical Field

[0001] This application relates to the field of steel cage hoisting technology, and in particular to a hoisting tool for drilled cast-in-place pile steel cages. Background Technology

[0002] As an important form of modern building foundation engineering, bored piles have become an indispensable key form in modern building foundation engineering due to their advantages such as high bearing capacity and adaptability to complex geological conditions. They are widely used in large-scale projects such as bridges and high-rise buildings. The reinforcing cage, as the core load-bearing component of the bored pile, plays a crucial supporting role.

[0003] However, traditional hoisting equipment is difficult to adapt flexibly to engineering steel cages of different sizes, and is prone to mismatch between clamps and steel cages. It is also prone to problems such as unreasonable distribution of clamps during hoisting, which can easily cause the steel cage to tilt and deform, affecting construction quality and safety. Furthermore, uneven stress can easily damage the steel cage, and there are certain drawbacks in its use.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail below.

[0033] A hoisting fixture for a bored pile reinforcement cage includes an H-beam 1 and a connecting beam 2. The connecting beam 2 is fixedly connected to the H-beam 1 by high-strength bolts 3. A connecting column 4 is fixedly installed at the bottom of the connecting beam 2, and a circular mounting block 5 is fixedly installed at the bottom of the connecting column 4. A rotating compression adjustment component 6 is installed on the circular mounting block 5. A limiting groove 7 is opened at the bottom of the circular mounting block 5, and a movable connecting component 8 is slidably installed in the limiting groove 7. One end of the movable connecting component 8 is slidably engaged in a connecting groove 9 opened on the inner wall of the limiting groove 7, and the other end of the movable connecting component 8 is connected to the rotating compression adjustment component 6. A hydraulic clamp 10 is installed on the movable connecting component 8. The hydraulic clamp 10 is divided into four groups and is evenly distributed below the circular mounting block 5. Four lifting lugs 11 are fixedly installed on the top of the H-beam 1 and are symmetrically distributed on the H-beam 1. In use, the fixture is hoisted above the reinforcement cage through the four symmetrical lifting lugs 11 on the top of the H-beam 1. Activating the rotating compression adjustment component 6 moves the movable connecting component 8 within the limiting slide groove 7 and connecting slot 9, adjusting the position of the hydraulic clamp 10. This allows for the hoisting of rebar cages of different sizes, providing flexibility for the steel frame. The evenly distributed hydraulic clamps 10 effectively improve hoisting stability and reduce the risk of rebar cage tilting and deformation. The hydraulic clamps 10 are then controlled to open, encircle the rebar cage, and then close to clamp it tightly. The rubber buffer layer 1006 helps prevent damage to the rebar cage, and finally, the cage is hoisted to the designated location.

[0034] Reference Figure 3and Figure 5 The rotary extrusion adjustment assembly 6 includes a servo motor 601 and a rotary extrusion disc 602. The servo motor 601 is fixed to the top of the circular mounting block 5. The rotary extrusion disc 602 is rotatably mounted on the bottom of the circular mounting block 5 via a rotary connecting shaft 603, and one end of the rotary connecting shaft 603 is fixedly connected to the output shaft of the servo motor 601. The rotary extrusion disc 602 has arc-shaped extrusion slots that are evenly distributed around the circumference and are fitted onto the movable connecting assembly 8. The movable connecting assembly 8 includes a first limiting slider 801 and a second limiting slider 802. The first limiting slider 801 is slidably mounted in the limiting groove 7, and the second limiting slider 802 is slidably engaged in the connecting groove 9. The second limiting slider 802 is fixedly connected to the first limiting slider 801. A smooth pressure-bearing column 803 is fixedly mounted on the first limiting slider 801 and is slidably inserted into the arc-shaped extrusion slot. A hydraulic clamp 10 is fixed to one end of the smooth pressure-bearing column 803. When using the rotary extrusion adjustment assembly 6, first start the servo motor 601 fixed on the top of the circular mounting block 5. Its output shaft drives the rotary connecting shaft 603 and the rotary extrusion plate 602 at the bottom to rotate. Because the arc-shaped extrusion slots evenly distributed around the circumference of the rotary extrusion plate 602 fit the smooth pressure-bearing column 803, they will squeeze the smooth pressure-bearing column 803, causing it to move with the first limit slider 801 in the limit groove 7 and the second limit slider 802 in the connecting slot 9. This, in turn, drives the hydraulic clamp 10 fixed at one end of the smooth pressure-bearing column 803 to move, thereby flexibly adjusting the position of the hydraulic clamp 10. This is suitable for hoisting steel cages of different sizes, facilitating the subsequent precise clamping and hoisting of the steel cages.

[0035] Reference Figure 5 The hydraulic clamp 10 includes a U-shaped connecting seat 1001 fixed to one end of a smooth pressure-bearing column 803. A first hydraulic cylinder 1002 and a second hydraulic cylinder 1003 are respectively fixedly installed at both ends of the U-shaped connecting seat 1001. A first gripper 1004 and a second gripper 1005 are respectively fixedly installed at the telescopic ends of the first hydraulic cylinder 1002 and the second hydraulic cylinder 1003. The first gripper 1004 and the second gripper 1005 are symmetrically distributed. A rubber buffer layer 1006 is fixedly installed on both the first gripper 1004 and the second gripper 1005. When it is necessary to clamp the reinforcing cage, the telescopic ends of the first hydraulic cylinder 1002 and the second hydraulic cylinder 1003 at both ends of the U-shaped connecting seat 1001 are retracted, which drives the symmetrically distributed first gripper 1004 and the second gripper 1005 to open. Move the first gripper 1004 and the second gripper 1005 to the steel cage, and then control the extension ends of the first hydraulic cylinder 1002 and the second hydraulic cylinder 1003 to extend, so that the first gripper 1004 and the second gripper 1005 close and clamp the steel cage. During this process, the rubber buffer layer 1006 can prevent damage to the steel cage. After that, the hoisting operation can be carried out.

[0036] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
