Abstract

The utility model discloses a lifting apparatus capable of automatically adjusting carrying pole beam balance. The lifting apparatus comprises a lifting tool main beam; two sets of connection frames respectively and longitudinally fixed on both ends of the lifting tool main beam; two sets of carrying pole beams, wherein the middle portions are respectively and rotatably connected with the two sets of the connection frames; four sets of lifting tools respectively connected with both ends of the two sets of the carrying pole beams; and two sets of stretching mechanisms, wherein one end of the stretching rod is rotatably connected with the carrying pole beam, and the other end is rotatably connected with the connection frame. With the lifting apparatus, the lifting process is stable, and a service life of the equipment can be increased.

Description

A kind of lifting appliance that can automatically adjust the shoulder pole girder balance

Technical field

The utility model relates to a kind of lifting appliance that can automatically adjust the shoulder pole girder balance.

Background technology

There is a kind of lifting appliance in prior art, comprise the suspender girder, suspender girder two ends arrange respectively two groups of suspenders, weight is fixed on suspender, then by driving tie-beam upwards with hoisting heavy, the problem that this lifting appliance exists is: due to the suspender that is placed in suspender girder two ends all for hoisting heavy, and in the process of hoisting heavy, because the weight of the weight of settling on suspender may be different, cause between tie-beam and suspender girder mechanical force excessive, easily cause Focal drug-block, and the lifting process is not steady, demands urgently improving.

The utility model content

For the problem that prior art exists, the purpose of this utility model is to propose a kind of lifting appliance that can automatically adjust the shoulder pole girder balance, can make the lifting process more steady, simultaneously, can increase the service life of equipment.

For reaching this purpose, the utility model by the following technical solutions:

A kind of lifting appliance that can automatically adjust the shoulder pole girder balance comprises the suspender girder; Two groups of link spans are vertically fixed in suspender girder two ends; Two groups of shoulder pole girders, wherein section is rotationally connected respectively two groups of link spans; Four groups of suspenders connect respectively two groups of shoulder pole girder two ends; Two groups of telescoping mechanisms, its expansion link one end is rotationally connected shoulder pole girder, and its other end is rotationally connected link span.Two groups of suspenders are symmetrical arranged with respect to link span.Two groups of suspenders are symmetrical arranged with respect to link span.

Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:

In the utility model, the weight fixed spreader, can disposable lifting organize weight more, simultaneously, adopt two groups of suspenders to fix on weight, lift by crane more stable, when two groups of suspenders and or when shakiness appears in hoisting heavy, adjust by telescoping mechanism, can make weight two groups of suspenders and or between keep balance.

The specific embodiment

Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:

Embodiment 1

Propose a kind of lifting appliance that can automatically adjust the shoulder pole girder balance, comprise suspender girder 1; Two groups of

link spans

31,32 are vertically fixed in suspender girder 1 two ends; Two groups of

shoulder pole girders

51,52, wherein section is rotationally connected respectively two groups of

link spans

31,32; Four groups of suspenders 21,22,23,24 connect respectively two groups of

shoulder pole girders

51,52 two ends; Two groups of

telescoping mechanisms

41,42, its expansion link 411,421 1 ends are rotationally connected

shoulder pole girder

51,52, and its other end is rotationally connected link span 31,32.Two groups of suspenders 21,22 are symmetrical arranged with respect to link span 31.Two groups of suspenders 23,24 are symmetrical arranged with respect to link span 32.

Weight 6 fixed spreaders 21,22,23,24, can disposable lifting organize weight 6 more, simultaneously, adopt two groups of suspenders 21,22 to fix on weight 6, lift by crane more stable, when two groups of suspenders 21,22 and/or two groups of suspenders 23,24 occur adjusting by telescoping mechanism 41/42 when unstable at hoisting heavy 6, can make weight 6 keep balance between two groups of suspenders 21,22 and/or two groups of suspenders 23,24.

The above; it is only the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or changed according to the technical solution of the utility model and utility model design thereof, within all should being encompassed in protection domain of the present utility model.
