Abstract

The utility model discloses a lifting tool, comprising a lifting plate, lifting chains, and lifting hooks; the center of the upper end surface of the lifting plate is provided with a lifting ring, and the edge of the lifting plate is provided with through holes for installing the lifting chains, meanwhile, one end of the lifting chain is connected in the through hole of the lifting plate, and the other end of the lifting chain is connected with one end of the lifting hook, and the lifting hook is in an L shape. The lifting plate is a circular plate; the through holes are evenly distributed at the circular plate. The upper end surface of the lifting plate is provided with strengthening ribs, and the strengthening ribs are connected with the lifting ring, and the strengthening ribs are distributed in a radiation way using the lifting ring as a center. And the L-shaped lifting hook is divided into a long-side section and a short-side section, and the included angle between the long-side section and the short-side section is less than 90 DEG. The lifting tool is particularly suitable for the lifting of workpieces or objects in large size, and has characteristics of simple structure, easy operating.

Description

A kind of lifting device

Technical field

The utility model relates to carrying, the lifting of material and uses equipment, is specifically related to a kind of lifting device.

Background technology

In the prior art, lifting device can be applicable to each class factory and carrier.In existing lifting device, be mostly to adopt an end that directly catches on steel rope or chain by suspension hook, again by the other end of steel rope or chain be connected by hoisted object.Though this lifting device is simple, easy-to-use, but for larger-size workpiece, when object lifts, because the angle between the steel rope under the suspension hook or the vertical line of chain and suspension hook is bigger, and the strong point has only one, when object is sling and need operation, object will aloft rock, when the size of object is big, very easily come off by hoisted object, or collide other equipment, personnel, building etc., this will be for by the object of handling, and lifting place, operating personals etc. bring great potential safety hazard, and when the size of object was big, difficulty of its lifting operation also can increase accordingly.

The utility model content

The purpose of this utility model is to overcome defective of the prior art, designs a kind of lifting device, and this lifting device is specially adapted to lift the workpiece or the object of large-size, and has the structure letter, the characteristics of single easy operating.

For achieving the above object, the technical solution of the utility model is to adopt a kind of lifting device, this lifting device comprises hanging scaffold, chain sling, suspension hook, center in described hanging scaffold upper surface is provided with suspension ring, be provided with the through hole that is used to install chain sling at the edge of described hanging scaffold, one end of described chain sling is connected in the through hole of described hanging scaffold, and the other end of described chain sling is connected with an end of described suspension hook, and described suspension hook is L-shaped.

Wherein, described hanging scaffold is a circular discs, and described through hole is rectangular distribution on described disk.

Wherein, the through hole on the described hanging scaffold has three.

Wherein, be provided with reinforced rib in the upper surface of described hanging scaffold, described reinforced rib is connected with described suspension ring, and described reinforced rib is that the center is emanant distribution with described suspension ring.

Wherein, described L shaped suspension hook is divided into long limit section and minor face section, and the angle between described long limit section and the minor face section is less than 90 degree.

Wherein, be provided with the bending section that tends to described minor face section at the long limit of described suspension hook section middle part, the bending angle of described bending section is 3～5 degree.

Wherein, be provided with lozenges in the end of described suspension hook minor face section, described lozenges is arranged on the lateral surface of described minor face section.

Advantage of the present utility model and beneficial effect are: owing to be provided with hanging scaffold in this lifting device, suspension hook is hooked on the central authorities of hanging scaffold, and an end of chain sling is installed in the edge of hanging scaffold, the other end of chain sling is connected with the suspension hook that is used to lift workpiece, and wherein the size of hanging scaffold can design according to the size of workpiece commonly used.This lifting device is specially adapted to lift the workpiece or the object of large-size, under the identical prerequisite of chain sling length, because angle is less between chain sling and the vertical line, and workpiece sling by three suspension hooks, because three lifting points can constitute a stable lifting plane, therefore, workpiece can be more steady in the process of lifting and operation, and this suspender also has simple in structure, and is with low cost, the characteristics of easy operating.

Among the figure: 1, hanging scaffold; 2, chain sling; 3, suspension hook; 3-1, long limit section; 3-1-1, bending section; 3-2, minor face section; 3-2-1, lozenges; 4, suspension ring; 5, through hole; 6, reinforced rib.

The specific embodiment

Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.

To shown in Figure 3, the concrete technical scheme of implementing of the utility model is as accompanying drawing 1:

A kind of lifting device, this lifting device comprises hanging scaffold 1, chain sling 2, suspension hook 3, center in described hanging scaffold 1 upper surface is provided with suspension ring 4, be provided with the through hole 5 that is used to install chain sling 2 at the edge of described hanging scaffold 1, one end of described chain sling 2 is connected in the through hole 5 of described hanging scaffold 1, the other end of described chain sling 2 is connected with an end of described suspension hook 3, and described suspension hook 3 is L-shaped.

In the utility model, described hanging scaffold 1 is a circular discs, described through hole 5 rectangular distribution on described disk.

In the utility model, the through hole 5 on the described hanging scaffold 1 has three.
