Description

Protection device for hoisting large part

Technical Field

The utility model relates to a water conservancy water and electricity civil engineering technical field, concretely relates to protection device of major possession hoist and mount.

Background

In the hoisting process of large steel members, concrete prefabricated members and the like, the requirements on the safety, the appearance quality and the applicability of the members in the construction process are high. Under the general hoisting condition, a hoisting steel wire rope is directly connected with a component hoisting point, the other end of the hoisting steel wire rope is connected with a lifting hook of hoisting machinery, and in the condition, the hoisting steel wire rope and a plane form an included angle, so that pressure towards the inner side is generated in the horizontal direction and borne by the component. In the hoisting process of the large member, due to the fact that the large member is heavy, horizontal direction and pressure are too large, the large member is prone to being damaged by coatings such as extrusion deformation, edge missing, corner falling, corrosion prevention, fire prevention and the like in the hoisting process, the member can be damaged when the coatings are serious, and serious quality and safety accidents are prone to being caused. Is not beneficial to the safety civilization management and the protection of component quality, is not beneficial to the safety of peripheral facilities and destroys the civilized construction image.

Disclosure of Invention

To the problem that exists among the background art, the utility model provides a protection device of major possession hoist and mount can effectively avoid large-scale steel member, concrete prefabricated component etc. to appear damaging in hoist and mount in-process, has guaranteed the appearance quality and the working property of hoist and mount component.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the protection device for hoisting the large part comprises a main supporting arm and an auxiliary supporting arm, wherein the main supporting arm and the auxiliary supporting arm are arranged in an orthogonal mode, the middle parts of the main supporting arm and the auxiliary supporting arm are mutually fixed and are connected and reinforced by reinforcing plates, inclined supports are arranged on four included angles between the main supporting arm and the auxiliary supporting arm respectively to be connected and reinforced, hoisting plates are arranged at the outer end parts of the main supporting arm and the auxiliary supporting arm respectively, an upper hoisting hole and a lower hoisting hole are symmetrically formed in each hoisting plate, and steel wire rope shackles are installed on the hoisting.

Preferably, the main supporting arm and the auxiliary supporting arm are both made of two symmetrically arranged channel steel which are connected through welding.

Preferably, the connection parts of the end parts of the inclined strut and the main supporting arm and the auxiliary supporting arm are reinforced by steel plate ribs.

The utility model has the advantages that:

1. the utility model discloses can effectively avoid large-scale steel member, concrete prefabricated component etc. to appear damaging at the hoist and mount in-process, guarantee the appearance quality and the working property of hoist and mount component.

2. The utility model provides the high efficiency of on-spot hoist and mount operation has reduced large-scale mechanical equipment, total input time to and the consumption of personnel, material, practiced thrift construction cost.

3. The utility model discloses can be under the whole of guaranteeing construction safety, reduce the influence to building on every side, reduce the safe risk of operation environment.
