Abstract

The utility model relates to a crane hoisting mechanism, in particular to a steel wire rope winding structure for a large-tonnage crane hoisting mechanism. The steel wire rope winding structure comprises winding drums, fixed pulley blocks, hook assemblies and a steel wire rope, a steel wire rope winding mechanism A and a steel wire rope winding mechanism B are connected through a balance pulley block arranged in the middle. One end of the steel wire rope is wound around the winding drum A and passes through the fixed pulley block A, the hook assembly A, the balance pulley block, the hook assembly B and the fixed pulley block B; the other end of the steel wire rope is wound around the winding drum B. The speed of the winding drum A or the winding drum B working independently is half of the nominal speed. The steel wire rope winding structure for the large-tonnage crane hoisting mechanism has the advantages of being good in synchronism, even and reasonable in steel wire rope stress, resistant to overload, safe, reliable, low in fault rate and the like; Two steel wire rope winding systems are connected together, once a driving device of the hoisting mechanism breaks down, the other driving device works at the half nominal speed, the whole hoisting mechanism is not overloaded, and safety and reliability are improved.

Description

Hoister in large tonnage hoisting mechanism steel wire rope winding structure
Technical field
The utility model relates to a kind of crane hoisting mechanism, particularly a kind of hoister in large tonnage hoisting mechanism steel wire rope winding structure.
Background technology
At present, the method for arranging of traditional hoister in large tonnage hoisting mechanism steel wire rope winding system, because lifting mechanism two cover actuating device wire rope winding devices are independent respectively, does not link together, and easily causes:
1., when suspension hook group two row's assembly pulleys hoist, steel wire can not be adjusted automatically, asynchronous, steel rope unbalance stress;
2. lifting mechanism, wherein during actuating device et out of order, easily causes another set of actuating device overload, has potential safety hazard.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of safe and reliable hoister in large tonnage hoisting mechanism steel wire rope winding structure is provided.
Scheme of the present utility model is as follows:
A kind of hoister in large tonnage hoisting mechanism steel wire rope winding structure, comprise reel, fixed pulley group, lifting hook pulley group and steel rope, the Liang Zu wirerope-winding A of mechanism and B, the equalizer pulley group arranging by centre connects, wherein steel rope one end starts to be wound around from reel A, via fixed pulley group A, lifting hook pulley group A, by equalizer pulley group, then be lifting hook pulley group B, fixed pulley group B, the other end is wound on reel B.
Described reel A or the reel B speed of working independently be command speed half.
The beneficial effects of the utility model:
Hoister in large tonnage hoisting mechanism steel wire rope winding structure of the present utility model, has synchronism good, and steel rope is stressed evenly, reasonable, and antioverloading is safe and reliable, the advantages such as failure rate is low;
Owing to increasing equalizer pulley group in the steel cable winding system device at lifting mechanism two cover actuating devices, two cover steel cable winding systems are linked together, once a set of actuating device et out of order of lifting mechanism, another set of actuating device carries out work with 1/2 command speed, whole lifting mechanism nonoverload, more safe and reliable.
Accompanying drawing explanation
Fig. 1 is that traditional hoisting mechanism steel wire rope is wound around schematic diagram.
Fig. 2 is the utility model hoister in large tonnage hoisting mechanism steel wire rope winding structure schematic diagram figure.
Wherein, in figure, mark 1 is reel A, and 2 is fixed pulley group A, and 3 is lifting hook pulley group A, and 4 is steel rope, and 5 is lifting hook pulley group B, and 6 is fixed pulley group B, and 7 is reel B, and 8 is equalizer pulley group.
The specific embodiment
embodiment mono-: referring to Fig. 1 to 2, a kind of hoister in large tonnage hoisting mechanism steel wire rope winding structure, comprise reel, fixed pulley group, lifting hook pulley group and steel rope, it is characterized in that: the Liang Zu wirerope-winding A of mechanism and B, the equalizer pulley group 8 arranging by centre connects, and wherein steel rope 4 one end start to be wound around from reel A, via fixed pulley group A, lifting hook pulley group A, by equalizer pulley group, be then lifting hook pulley group B, fixed pulley group B, the other end is wound on reel B.
Described reel A or the reel B speed of working independently be command speed half.
The method for arranging of the utility model hoister in large tonnage hoisting mechanism steel wire rope winding system, owing to increasing equalizer pulley group in the steel cable winding system device at lifting mechanism two cover actuating devices, two cover steel cable winding systems are linked together, form a unified winding system.In addition, once due to a set of actuating device et out of order of lifting mechanism, another set of actuating device carries out work with 1/2 command speed, and whole lifting mechanism nonoverload is more safe and reliable.

Claims (2)

1. a hoister in large tonnage hoisting mechanism steel wire rope winding structure, comprise reel, fixed pulley group, lifting hook pulley group and steel rope, it is characterized in that: the Liang Zu wirerope-winding A of mechanism and B, the equalizer pulley group arranging by centre connects, wherein steel rope one end starts to be wound around from reel A, via fixed pulley group A, lifting hook pulley group A, by equalizer pulley group, then be lifting hook pulley group B, fixed pulley group B, the other end is wound on reel B.
2. hoister in large tonnage hoisting mechanism steel wire rope winding structure according to claim 1, is characterized in that: described reel A or the reel B speed of working independently be command speed half.
