Lifting appliance for mounting steel support

Abstract

The utility model discloses a lifting appliance for mounting a steel support, which adopts a hanging mesh formed by fixedly connecting lifting belts in a criss-cross manner, bearing rods are arranged on two sides of the hanging mesh, limiting grooves in one-to-one correspondence with the transverse lifting belts are arranged on the bearing rods, and the end parts of the transverse lifting belts of the hanging mesh are wound and fixed in the limiting grooves. According to the utility model, the hanging net sheet formed by fixedly connecting the hanging belts in a criss-cross manner is adopted, and a plurality of hanging belts act at the same time, so that the stress condition of the whole lifting appliance cannot be collapsed under the condition that one hanging belt is damaged, and the safety of hoisting is enhanced; compared with steel wire rope hoisting, the contact area between the hanging mesh and the steel support is large, the friction force is large, and slippage and inclination are not prone to occurring; the bearing rod can replace a hoisting shoulder pole to share the stress condition of the steel wire rope, so that the stress of the steel support is more uniform. And the device is simple in structure, convenient to use and low in manufacturing cost.

Description

Technical Field

[0001] This utility model belongs to the field of lifting and hoisting technology, and specifically relates to a lifting device for steel support installation. Background Technology

[0002] In the construction process, the horizontal hoisting of tubular components such as steel supports is a crucial aspect of construction safety management. As an important component of foundation pit support, the safe and reliable installation process of steel supports is a key focus of construction management. However, the traditional hoisting process for steel supports has exposed some safety issues. In the past, steel supports were hoisted by securing both ends with wire ropes (or by adding a hoisting spreader). The friction between the wire ropes and the steel supports was relatively small, often resulting in wire rope slippage and causing the steel supports to tilt. This seriously affected construction safety and the horizontal alignment of the steel supports during installation. Consequently, bolts were difficult to align during the splicing process, which could lead to hoisting accidents in severe cases. Utility Model Content

[0003] This utility model provides a lifting device for installing steel supports to solve the technical problems existing in the prior art, which can prevent the steel supports from overturning.

[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: a lifting device for steel support installation, which adopts a hanging net sheet formed by crisscrossing and fixedly connected lifting straps. The hanging net sheet is provided with load-bearing rods on both sides, and the load-bearing rods are provided with limiting grooves corresponding to the horizontal lifting straps. The ends of the horizontal lifting straps of the hanging net sheet are wrapped and fixed in the limiting grooves.

[0005] Based on the above solution, the present invention has made the following improvements:

[0006] Each of the limiting grooves is composed of two limiting retaining rings that are fixed to the load-bearing rod.

[0007] The horizontal and vertical straps of the hanging mesh are both made of flat polyester straps.

[0008] The limiting retaining ring is connected to the load-bearing rod by a double-sided weld.

[0009] The length of the hanging net is 1.5 to 2.5 m.

[0010] The load-bearing rod is made of thick-walled steel pipe or steel bar.

[0011] The advantages and positive effects of this utility model are as follows: Because it uses a hanging net sheet formed by crisscrossing slings, multiple slings work simultaneously, preventing the entire lifting apparatus from collapsing if one sling fails, thus enhancing the safety of lifting operations. Compared to wire rope lifting, the hanging net sheet has a larger contact area with the steel support, resulting in greater friction and reducing the likelihood of slippage or tilting. The load-bearing rod can replace the function of the lifting spreader, distributing the stress on the wire rope and making the stress on the steel support more even. Furthermore, this utility model has a simple structure, is easy to use, and has low manufacturing costs. Attached Figure Description

[0016] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0017] Please see Figure 1 and Figure 2 A lifting device for steel support installation uses a hanging net 3 formed by crisscrossing and fixed slings. The hanging net 3 has load-bearing rods 5 on both sides, and the load-bearing rods 5 have limiting grooves that correspond one-to-one with the horizontal slings 1. The ends of the horizontal slings 1 of the hanging net 3 are wrapped and fixed in the limiting grooves.

[0018] The more preferred solution in this embodiment is as follows:

[0019] Each of the limiting grooves is composed of two limiting retaining rings 4 that are fixedly connected to the load-bearing rod 5, and does not affect the load-bearing capacity of the load-bearing rod.

[0020] The horizontal straps 1 and vertical straps 2 of the hanging mesh 3 are both made of flat polyester straps, with a large contact surface and good anti-slip properties.

[0021] The limiting ring 4 is connected to the load-bearing rod 5 by double-sided welds, ensuring a strong connection.

[0022] The length of the hanging net 3 is 1.5 to 2.5m, which can take into account both anti-overturning and cost aspects.

[0023] The load-bearing rod 5 is made of thick-walled steel pipe or steel bar, which can withstand large torque, and is lightweight and high-strength.

[0024] When using it, wrap the above-mentioned lifting tool around the center of gravity of the steel support, install a horseshoe-shaped lifting ring behind the end of the transverse lifting strap and at the end of the load-bearing rod, and carry out the lifting operation after the test lift is stable.

[0025] Although the preferred embodiments of the present invention have been described above in conjunction with the accompanying drawings, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the protection scope of the present invention.
