Abstract

The utility model provides a roof beam is hung to lifting hook flexible connection formula crane, it includes parts such as lifting hook, crossbeam, and characterized by installs adapting unit such as position installation lifting hook pivot, yoke plate, round pin axle and arm-tie on the crane crossbeam for the lifting hook is installed on the crossbeam, makes the swing of lifting hook not receive the restraint of hanging the roof beam body, and the lifting hook can swing at will between the roof beam body with hanging, forms flexible connection. In order to reduce the influence of the increased connecting pieces such as the pulling plate on the lifting height, the cross beam is provided with a groove, and partial parts are arranged in the groove to ensure that the lifting hook group moves upwards. In addition, in order to ensure the strength of the cross beam, a reinforcing member is additionally arranged at the upper part of the cross beam. The utility model has the advantages of flexibility is good, the swing is free, has solved prior art because the lifting hook with hang between the roof beam rigid connection and lead to the lifting hook root to bear the easy fracture scheduling problem that produces of moment effect, has eliminated the potential safety hazard, has improved the life of lifting hook.

Description

Suspension hook flexible-disc joint formula crane drop in beam

Technical field

The utility model belongs to lifting equipment, particularly a kind of suspension hook flexible-disc joint formula crane drop in beam of double hook drop in beam formula crane.

Background technology

The crane drop in beam is mounted in the special hanger of drop in beam crane double hook bottom, is one of major part of drop in beam crane.Usually the double hook of double hook drop in beam formula crane distance is bigger, hangs with drop in beam in the lower end of double hook, arranges that on drop in beam many group suspension hooks are used for the lifting job of special article.Be used for article such as handling steel plate, steel billet in steel rolling mill more.

At present, the version that the crane drop in beam generally adopts is by component set-ups such as suspension hook and drop in beams, and suspension hook directly is installed on the drop in beam with inserted, between suspension hook and the drop in beam for being rigidly connected.Therefore, when the handling article, the oscillatory forces of article causes between suspension hook and the drop in beam and forms moment, and suspension hook easily cracks at root after bearing moment, and fracture causes a hidden trouble to safety in production easily.

Summary of the invention

The purpose of this utility model is that the suspension hook of existing double hook drop in beam formula crane is transformed, thereby a kind of suspension hook flexible-disc joint formula crane drop in beam is provided.It is by the position that suspension hook is installed links such as arm-tie, yoke plate to be installed suspension hook is installed on the crossbeam on the crane crossbeam, makes the swing of suspension hook not be subjected to the constraint of drop in beam body, can arbitrarily swing the formation flexible-disc joint between suspension hook and the drop in beam body.It has flexible good, advantage such as swing freedom etc., has solved prior art and has caused the suspension hook root to bear moment loading easily producing problems such as fracture, eliminated potential safety hazard, improved the service life of suspension hook owing to being rigidly connected between suspension hook and the drop in beam.

The utility model is achieved in that it comprises parts such as suspension hook, crossbeam, is characterized in that: the connecting portion at suspension hook and crossbeam has increased attaching partss such as suspension hook rotating shaft, yoke plate, bearing pin and arm-tie.Concrete structure is, is welded with arm-tie on crossbeam, connects attaching partss such as yoke plate and suspension hook rotating shaft by bearing pin, and suspension hook is installed in the suspension hook rotating shaft, forms complete crane drop in beam.For reducing owing to increase of the influence of attaching parts such as arm-tie to lifting altitude, on crossbeam design fluted, part is installed in the groove, make on the suspension hook group and move.In addition, for guaranteeing the intensity of crossbeam, have additional reinforcing member on the top of crossbeam.

The utility model has overcome the deficiencies in the prior art, has following advantage:

1. suspension hook has good flexiblely, has solved because the problem that the institute's suspension hook that causes that is rigidly connected between suspension hook and the drop in beam ruptures easily eliminates safe hidden trouble, and ensures safety in production.

2. suspension hook has parallel or perpendicular to the degree of freedom that the drop in beam girder is swung, swings the constraint of not weighed, and can disperse the damage of the swing of institute's handling weight to the suspension hook root, reduces the suspension hook time of casualty, and prolong service life, remarkable in economical benefits.

3. adopt form of grooves that suspension hook is installed on the inside of crossbeam, increase the actual lifting altitude of crane, compact conformation.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the A-A section-drawing of Fig. 1

Among the figure: suspension hook 1, yoke plate 2, suspension hook rotating shaft 3, bearing pin 4, groove 5, arm-tie 6, crossbeam 7, reinforcing member 8.

The specific embodiment

Below in conjunction with the embodiment in the accompanying drawing the utility model is described in detail: be that the modification scheme of 20 tons of crane drop in beams is an example only with load-carrying capacity, as shown in the figure, welding arm-tie 6 (material 16Mn on crossbeam (crane drop in beam) 7, δ=16mm), by bearing pin 4 (material 45, ∮ 120 * 440mm) connects yoke plates 2 (material 16Mn, δ=16mm) and suspension hook rotating shaft 3 attaching partss such as (standard lifting beam with hook), suspension hook 1 is installed in the suspension hook rotating shaft 3, forms complete crane drop in beam.Reserve groove 5 (width 430mm, degree of depth 200mm) on crossbeam 7, be used to install bearing pin 4 parts such as grade, make on the position of suspension hook group and move, improve lifting altitude, the degree of depth of groove 5 can be determined according to the needs of the actual lifting altitude in scene.In addition, set up reinforcing member 8, to guarantee the intensity of crossbeam on the top of crossbeam 7.

Claims
