Description

Multi-lifting point eccentric spreader

technical field

The utility model relates to the technical field of special slings, in particular to an eccentric sling with multiple lifting points.

Background technique

Generally speaking, hoisting operations do not require special special spreaders. However, we still often encounter blind areas or corners in hoisting, especially when working in the workshops of large factories and mines. The crane in the workshop often cannot be hoisted directly, and it cannot be stretched with other cranes.

For example, the large cooling bed in a metallurgical factory is generally located in several consecutive spans of the workshop. If mechanical equipment is installed under the crane beam, or the mechanical equipment below needs to be hoisted out for maintenance, if there is no special lifting gear, it is difficult for the workshop to complete the task. However, there is a great safety risk. If the hook is pulled obliquely, it will cause the wire rope to fall out of the groove. It will damage the lifting equipment and cause safety accidents.

Utility model content

In view of the above technical problems, the purpose of this utility model is to provide a multi-lift point eccentric spreader, which is designed according to the principle of lever balance, and can easily lift in place or disassemble the mechanical equipment located in the dead zone or corner of the workshop. down.

For realizing above-mentioned purpose, the technical scheme that the utility model takes is:

A multi-suspension-point eccentric spreader is characterized in that it includes a hanging plate and a counterweight, one end of the hanging plate is provided with a first lifting point for hanging the counterweight, and the other end is provided with a second hanging point for hanging mechanical equipment. There are two lifting points, and the middle part is provided with a third lifting point for hanging connection with lifting equipment.

The hanging plate is a box-shaped structure welded by steel plates.

The first lifting point and the second lifting point are provided with a plurality of through holes, and the plurality of through holes are located on the same straight line; each through hole is provided with a connecting steel pipe, and both ends of the connecting steel pipe are provided with limit steel plate.

A pair of circular holes is provided at the third lifting point, a connecting steel pipe is arranged in each through hole, and both ends of the connecting steel pipe are provided with limiting steel plates.

The beneficial effects of the utility model are: the sling is designed according to the principle of lever balance, and the mechanical equipment is transported to a certain distance (generally no more than 3.5m) in the horizontal displacement direction of the hook through the eccentric hoisting method (balanced with an adjustable counterweight). , can easily hoist in place or disassemble the mechanical equipment located in the blind area or dead corner of the workshop. The use of the spreader can not only speed up the progress of the project, reduce the labor intensity of the operators, but also improve the work efficiency and save the construction period. The spreader can be obtained locally, is easy to process, low in cost, safe and convenient to use, and easy to maintain. Moreover, the spreader has a simple structure, is easy to manufacture, and does not require special processing equipment; the spreader is small in size and light in weight, and basically does not occupy space for storage; the spreader can be used repeatedly and is easy to maintain.

Detailed ways

In order to better understand the utility model, the technical solution of the utility model will be further described below in conjunction with the embodiments and accompanying drawings (shown in Figures 1-3).

An eccentric hoisting device with multiple lifting points, which includes a hanging plate 1 and a counterweight 2, one end of the hanging plate 1 is provided with a first lifting point 4 for hanging the counterweight 2, and the other end is provided with a 3 for hanging mechanical equipment The second lifting point 5, the middle part is provided with the third lifting point 6 for hanging connection with the lifting equipment.

The hanging plate 1 is a box-shaped structure formed by welding (front, rear, left, right, up, down, etc.) steel plates.

The first lifting point 4 and the second lifting point 5 are (uniformly) provided with a plurality of through holes, and the plurality of through holes are all located on the same (horizontal) straight line; each through hole is provided with a connecting steel pipe 7 ( Both ends of the connecting steel pipe 7 are beyond the hanging plate 1, and both ends are symmetrical with the hanging plate 1 as the center), and both ends of the connecting steel pipe 7 are provided with limiting steel plates 8 .

The third hanging point 6 is provided with a pair of round holes, and each through hole is provided with a connecting steel pipe 7 (both ends of the connecting steel pipe 7 are beyond the hanging plate 1, and both ends are symmetrical with the hanging plate 1 as the center) , both ends of the connecting steel pipe 7 are provided with limiting steel plates 8 .

The limiting steel plate 8 is circular or square, its diameter or circumscribed circle diameter is larger than the diameter of the connecting steel pipe 7, and is arranged concentrically with the connecting steel pipe 7.

The connecting steel pipe 7 is used to connect with the counterweight 2, the mechanical equipment 3 and the suspension hook through steel ropes.

The above descriptions are only application examples of the utility model, and of course the scope of rights of the utility model cannot be limited with this. Therefore, equivalent changes made according to the patent scope of the utility model still belong to the protection scope of the utility model.
