CN200961083Y - Cross-shape four-shaft hook crossbeam - Google Patents

Abstract

The utility model relates to a cruciform hook beam with four shafts, improving hanging method when a universal crane using an electric rolling sling. The material method is that a couple of shafts are equipped in the plane vertical direction of a traditional I-shaped hook beam with two shafts and make the hook beam into a cruciform hook beam with four shafts. An electric rolling sling hanging on the couple of enhancive shafts controls the sling rotate horizontally and freely, when a gravity of a load deflects, the sling can adjust center of gravity by swaying in length and breadth automatically, a pulley block keeps vertical continually, thereby avoiding that the pulley block sways and leads cable wire to doff a groove.

Description

Criss-cross four shaft extension lifting beam with hook

Technical field

The utility model relates to the parts of crane hook assembly pulley, is universal hoisting crane is hung parts when using electronic rotary hanger improvement.

Background technology

When present electronic rotary hanger is suspended on the suspension hook operation, need clamp suspension hook, forbid that it rotates freely, simultaneously suspender has been lost on suspension hook, to freely swing to keep the vertical ability of center of gravity, as practicality novel 03277085.5 with the back plate of slotting on the suspender.When the goods center of gravity in when, with the sheave shaft parallel direction skew taking place, suspender will force assembly pulley to tilt, and the accident that steel rope is deviate from from pulley groove takes place during the lifting operation easily.

Summary of the invention

Task of the present utility model provides a kind of criss-cross four shaft extension lifting beam with hook, is used to solve existing electronic rotary hanger and is suspended on suspension hook, in the goods center of gravity skew takes place and makes suspender tilt to cause the assembly pulley steel rope to go out the problem of groove easily.Specific practice is: traditional in-line twin shaft is stretched lifting beam with hook (Fig. 2) be improved to criss-cross four shaft extension lifting beam with hook (Fig. 3).Electronic rotary hanger no longer is suspended on the suspension hook 4 and directly is suspended on a pair of shaft extension that lifting beam with hook sets up, suspender can be along two intersection axle center of lifting beam with hook, horizontal, vertical bidirectional swinging, no matter how crooked assembly pulley 1 remains vertically suspender, simultaneously, because electric lifting tool directly hangs over the lifting altitude that has also improved suspender on the criss-cross four shaft extension lifting beam with hook (Fig. 3).

Description of drawings

Fig. 1 is the structural representation of lifting hook pulley group.

Fig. 2 is a traditional word lifting beam with hook scheme drawing.

Fig. 3 is the utility model criss-cross four shaft extension lifting beam with hook scheme drawings.

The specific embodiment

The a pair of shaft extension of yoke plate on the assembly pulley 12 and criss-cross four shaft extension lifting beam with hook (Fig. 3) is connected, electronic rotary hanger back plate is hung on the other a pair of shaft extension of criss-cross four shaft extension lifting beam with hook (Fig. 3), so no matter electronic rotary hanger how deflection, goods center of gravity and assembly pulley 1 remain on the vertical line, have avoided going out the groove obscission because of the steel rope that the assembly pulley deflection causes.

Claims (1)

1, a kind of criss-cross four shaft extension lifting beam with hook, be to stretch a kind of improvement on the lifting beam with hook basis at existing in-line twin shaft, it is characterized in that: the plane vertical direction of stretching lifting beam with hook at traditional in-line twin shaft is set up a pair of shaft extension makes it to become criss-cross four shaft extension lifting beam with hook, and a pair of shaft extension of setting up is used to hang electronic rotary hanger.
