Description

a lifting tool

technical field

The utility model relates to the field of hoisting equipment, in particular to a hoisting tool.

Background technique

In order to ensure a smooth and beautiful appearance, some large-scale box-type equipment is not allowed to weld lifting lugs on the equipment itself for direct lifting in terms of force. purpose of lifting or moving.

Therefore, how to design a brand-new hoisting tool that can directly hoist large-scale equipment without additional welding auxiliary devices on large-scale box-type equipment is a problem to be solved by those skilled in the art.

Utility model content

The purpose of this utility model is to provide a kind of hoisting tool in order to overcome the deficiency of above-mentioned prior art. The hoisting tool provided by the utility model can directly hoist large box-type equipment without additional welding auxiliary devices.

In order to achieve the above object, the utility model adopts the following technical solutions:

A lifting tool, comprising:

box beams;

at least one set of hoisting mechanisms mounted on the box beam;

Wherein: the lifting mechanism includes a hook hinged with the box-shaped beam, a pulley arranged at the end of the box-shaped beam, a power mechanism is installed on the box-shaped beam, the power mechanism is connected with the hook through a traction rope, and the traction The rope is guided by a pulley;

The inner side of the hook has at least one flat surface.

Preferably, the lifting mechanisms are in two groups.

Preferably, there are four sets of lifting mechanisms.

Preferably, the hook is hinged to the box-shaped beam through a pin.

Preferably, the power mechanism is a reel.

The beneficial effect of the utility model is that the bottom of large box-type equipment can be hoisted directly through the hoisting mechanism, and the hoisting of the equipment can be realized without welding auxiliary devices on the equipment.

Description of drawings:

In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments or the prior art. Obviously, the accompanying drawings in the following description These are only some embodiments of the utility model, and those skilled in the art can also obtain other drawings based on these drawings without creative work.

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the application state figure of the utility model;

Among them: 1. Box beam, 2. Hook, 3. Pin shaft, 4. Reel, 5. Pulley, 6. Traction rope.

Detailed ways:

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Embodiment 1: a kind of hoisting tool, its structure as shown in Figure 1, comprises:

box beam 1;

at least one set of hoisting mechanisms mounted on the box beam;

Wherein: the lifting mechanism includes a hook 2 hinged with the box-shaped beam 1, the hook 2 has lifting lugs, a pulley 5 arranged at the end of the box-shaped beam 1, and a power mechanism is installed on the box-shaped beam 1, The power mechanism is connected with the lifting lug through the traction rope, and the traction rope is guided by the pulley;

The inside of the hook 2 has at least one plane.

There are four groups of lifting mechanisms.

The hook 2 is hinged on the box-shaped beam 1 through a pin shaft 3 .

The power mechanism is the reel 4 .

The box-shaped beam 1 and the suspension hook 2 are connected together with a pin shaft 3, and the inner side of the suspension hook 2 has a plane structure, which can prevent the suspension hook 2 from being damaged due to too concentrated force during the hoisting process.

When the device is lowered to just contact with the hanging object, let the reel 4 rotate forward, then the traction rope 6 will pull the hook 2 away, and then stop the hoisting; continue to descend, when the hanging object is located inside the hook 2, The reel 4 is reversed again, and the hook 2 is transformed into a free state until it contacts with the hanging object, and the reliability is checked, and the reel 4 is forwardly rotated again, and the hook 2 is just stuck in the bottom of the hanging object, and is automatically in place. By controlling the eccentric distance between the pin shaft 3 and the hook 2, the self-locking of the hook 2 can be realized.

Embodiment 2: A hoisting tool, the structure of which is still as shown in Fig. 1, the difference from Embodiment 1 is that the hoisting mechanisms are in two groups.

Each embodiment in this specification is described in a progressive manner, each embodiment focuses on the difference from other embodiments, and the same and similar parts of each embodiment can be referred to each other.

The above description of the disclosed embodiments enables those skilled in the art to realize or use the utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
