Abstract

The utility model provides a balance lifting tool for lifting of two cranes, which comprises a lifting hook assembly, a horizontally-arranged balancing frame and lifting ropes and is characterized in that two pulley groups are symmetrically arranged at two ends of the balancing frame. Each pulley group consists of two pulleys arranged coaxially and parallelly, the lifting hook assembly is installed in the middle of the balancing frame, each lifting rope penetrates through two pulleys arranged on the same side, a lifting rope limiting clamp is fixed on each lifting rope above each pulley group, a support rod is arranged on the lifting rope limiting clamp, and the length of the support rod is identical with the pulley groove space of the same group of pulleys. By means of the balance lifting tool for the lifting of the two cranes, loading weights born by the two cranes are equal when the two cranes lift goods. Simultaneously, the balance of the goods can be ensured by adjustment of the balancing frame when the two lifting cranes are asynchronous in lifting speed, thereby eliminating potential safety hazards.

Description

A kind of double crane lifts balance sling

Technical field

The utility model relates to a kind of suspender, and particularly a kind of double crane lifts balance sling.

Background technology

At present; When the lifting of separate unit loop wheel machine can't be worked above the goods spare of inherently safe load; Adopt two loop wheel machines to lift the lifting problem that solves goods spare; But there are some defectives in actual use in this hoisting method: if the 1. center of gravity relative equilibrium of goods spare, but when two loop wheel machine lifting velocities were asynchronous, goods spare overbalance will take place; 2. when the center of gravity of goods spare had deviation or deviation big, a loop wheel machine event of overload appearred in loading overbalance that two loop wheel machines that lift are born sometimes, and inferior Hoisting Program exists certain potential safety hazard.

Summary of the invention

The utility model technical matters to be solved is the deficiency to prior art; Provide a kind of reasonable in design; Two loading balance and goods spare balances that loop wheel machine is born when guaranteeing that two loop wheel machines lift great goods spare, the nonsynchronous double crane of scalable loop wheel machine lifting velocity lifts balance sling simultaneously.

The utility model technical matters to be solved is to realize through following technical scheme.The utility model is that a kind of double crane lifts balance sling, and it comprises suspension hook assembly and horizontally disposed equalizer bar, is characterized in: the equalizer bar two ends are arranged with two assembly pulleys; Each assembly pulley is made up of coaxial two pulleys that laterally arrange; The suspension hook assembly is installed in the middle part of equalizer bar, and it also is provided with lifting rope, and lifting rope passes two pulleys of homonymy; Be fixed with the spacing card of lifting rope on the lifting rope of each assembly pulley top, the spacing card of lifting rope is provided with the strut bar that equates with the wheel separation of pulley on the same group.

Compared with prior art, when using the utility model can make two loop wheel machines lift goods spare, two loads that loop wheel machine bore are equal in weight, and are lifting the loop wheel machine lifting velocity when asynchronous simultaneously, regulate guaranteeing goods spare balance through equalizer bar, eliminate safe hidden trouble.

The specific embodiment

Following with reference to accompanying drawing, further describe the concrete technical scheme of the utility model, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.

Embodiment 1, and with reference to Fig. 1, Fig. 2 and Fig. 3, a kind of double crane lifts balance sling; It comprises suspension hook assembly 5 and horizontally disposed equalizer bar 2, and equalizer bar 2 two ends are arranged with two assembly pulleys, and each assembly pulley is made up of coaxial two pulleys 1 that laterally arrange; Suspension hook assembly 5 is installed in the middle part of equalizer bar 2; It also is provided with lifting rope 4, and lifting rope 4 can be steel rope, and lifting rope 4 passes two pulleys 1 of homonymy; Be fixed with the spacing card 6 of lifting rope on the lifting rope 4 of each assembly pulley top, the spacing card 6 of lifting rope is provided with the strut bar 3 that equates with the wheel separation of pulley 1 on the same group.The two ends of strut bar 3 can be provided with pushing out ring, and lifting rope 4 passes the pushing out ring at strut bar 3 two ends respectively, and strut bar 3 can make lifting rope 4 parallel with the race of pulley 1, the phenomenon that lifting rope 4 breaks away from race can not occur.

During use; Equalizer bar 2 two ends lifting ropes 4 are hung on the hook of the loop wheel machine that lifts goods spare; The suspension hook assembly 5 at equalizer bar 2 middle parts is connected with the goods spare hoist cable that is lifted; The weight of goods spare concentrates on the middle part of equalizer bar 2 through suspension hook assembly 5 in the work, thereby makes whole suspender balance, and two loop wheel machine bonded assembly lifting ropes 4 guarantee two load phase isoequilibriums that loop wheel machine carried through assembly pulley; When two loop wheel machine lifting velocities are asynchronous, can regulate, with the equalizer bar 2 of assurance balance sling and the balance and stability of goods spare through lifting rope 4 and assembly pulley.

Claims

1. a double crane lifts balance sling, and it comprises suspension hook assembly and horizontally disposed equalizer bar, it is characterized in that: the equalizer bar two ends are arranged with two assembly pulleys; Each assembly pulley is made up of coaxial two pulleys that laterally arrange; The suspension hook assembly is installed in the middle part of equalizer bar, and it also is provided with lifting rope, and lifting rope passes two pulleys of homonymy; Be fixed with the spacing card of lifting rope on the lifting rope of each assembly pulley top, the spacing card of lifting rope is provided with the strut bar that equates with the wheel separation of pulley on the same group.
