Description

An adjustable polygon spreader

technical field

The utility model belongs to the technical field of mechanical design, and in particular relates to a sling structure technology.

Background technique

During the transportation of heavy equipment, it is often necessary to lift, and a spreader is required. For example, during the production, transportation and installation of medium voltage switchgear, it is necessary to use the spreader many times. In order to ensure the convenience, safety, efficiency and stability of lifting, the spreader is required to have the characteristics of flexible adjustment, quick disassembly and assembly, wide adaptability and stable connection.

The traditional spreader has a fixed shape, and cannot adapt to various shapes for irregular lifting objects. When lifting and installing multiple times, it is necessary to test multiple positions, repeatedly disassemble and assemble, and delay time. Spreaders with a single connection point, using wire ropes, may slip and increase the unsafe factor.

Utility model content

In order to solve the problems existing in the prior art, the present utility model proposes an adjustable polygonal hanger. In order to achieve the above purpose, the present utility model adopts the following technical solutions.

The polygon spreader includes a plurality of brackets. The upper part of each bracket is installed with a lifting ring nut and the lower part is installed with a lifting ring. The two sides of the bracket form an included angle, and each edge is embedded with an adjustment rod. The bracket is used as a vertex of the polygon. The adjustment rod as an edge of the polygon.

The adjustment rod and the bracket are provided with a plurality of through holes, the adjustment bolts pass through the through holes, and the adjustment rod and the bracket are fixed without relative movement.

The adjustment rod is drawn out or inserted along the bracket to extend or shorten the side length of the polygon.

Further, the adjustment rod can be replaced with different lengths.

Further, the bracket can be replaced with different angles.

The included angle between the two sides of the bracket is 90 degrees, forming a quadrilateral.

The beneficial effects of the utility model are as follows: the lower part of each bracket is provided with a hoisting ring, and the multiple hoisting rings provide a plurality of hoisting force points, which is more dispersed than the traditional single-point hoisting force and reduces the load of a single hoisting rope. Safer; according to the size of the lifting object, the side length of the polygon can be adjusted in real time to adapt to the size of the binding, without having to replace the spreader, which is fast and efficient; according to the shape of the lifting object, the brackets with different angles can be replaced to meet the needs of the binding, flexible and multi-purpose ; Use the sling to adapt to the lifting object, for the lifting object of non-rigid material, it can well protect it from deformation when it is stressed.

Description of drawings

Fig. 1 is a structural diagram of a spreader, and Fig. 2 is an explanatory diagram of use.

Description of drawings: 1- lifting ring nut, 2- adjusting bolt, 3- adjusting rod, 4- bracket, 5- lifting ring, 6- rectangular short side, 7- rectangular long side.

Detailed ways

The technical solution of the present utility model will be described in detail below by taking a quadrilateral spreader as an example in conjunction with the accompanying drawings.

The structure of the quadrilateral spreader is shown in Figure 1, including four brackets 4, the upper part of each bracket is installed with a lifting ring nut 1, and the lower part is installed with a lifting ring 5, the two sides of the bracket form a 90-degree angle, and each edge is embedded The adjustment rod 3 is provided with a plurality of through holes, and the adjustment bolt 2 passes through the through holes, and the fixed adjustment rod and the bracket do not move relative to each other.

The use of the quadrilateral spreader is shown in Figure 2. The lifting object is a cuboid, one side is long and the other is short. Insert a pair of adjustment rods of the quadrilateral spreader into the bracket to shorten the side length to form a rectangular short side 6, and the other pair of adjustment rods are pulled out of the bracket , Extend the side length to form a rectangular long side 7 to adapt to the shape of the lifting object, keep the center of gravity inside the spreader, and four lifting rings 5 fix the lifting object, and the weight is shared by it.

The above-mentioned embodiments of the present utility model do not limit the present utility model, and any modifications, equivalent replacements and improvements made within the spirit and principle of the present utility model are all included within the protection scope of the present utility model.
