The present invention discloses one kind of slinging equipment of crane. The slinging equipment consists of winches, steel cables, hoisting hooks and crane crossbeams. There are three or more winches, each of which is connected through one steel cable to the upper and lower lead pulleys, fixed pulley block and sling dog assembly. The sling dog assembly comprises fixed hooks with sling and sling dog body comprising over two equalizing beams connected through axles. The present invention has the features of great hoisting tonnage, even stress, high safety and reliability, and simple structure.
Description
Technical field
The invention belongs to the weight-lifting equipment technical field, especially relate to a kind of jack up unit of building offshore platform with the large-tonnage loop wheel machine.
Background technology
In hoisting engineering, be extensive use of turned crane at present, the jack up unit of existing loop wheel machine generally adopts and be fixed with a winch on hoisting machine cross beam, winch is by steel rope and single fixed pulley and lifting hook pulley winding, lifting hook pulley is provided with suspension hook, the jack up unit of this structure, can satisfy the needs of most of occasions of determining, but when hoisting the above weight of ton for large-scale loop wheel machine, present jack up unit is because the restriction of structure, can't meet requirements, have the stressed more concentrated of jack up unit now, suspension centre is less, and the problem that erecting equipment damages takes place in the process of hoisting easily, is both because with respect to the thing that hoisted, stressed concentrating in the process causes suspended object to damage easily owing to hoist.
Summary of the invention
The objective of the invention is to improve the deficiency of prior art and provide a kind of lifting tonnage huge, stressed hoisting device for loop wheel machine even, safe and reliable, simple in structure.
The object of the present invention is achieved like this, a kind of hoisting device for loop wheel machine, be by winch, steel rope, lifting hook and hoisting machine cross beam are formed, the winch that is characterized in jack up unit is more than 3, winch is reduced to the center by the hoisting machine cross beam end successively along distribution of hoisting machine cross beam direction and height, the opposite side at hoisting machine cross beam middle part be fixed with the winch equal number on leading sheave, last leading sheave height is reduced to the center successively by nearside hoisting machine cross beam end, the bottom of hoisting machine cross beam is provided with and the same number of leading sheave down of last leading sheave, be fixed with the fixed pulley group on the below hoisting machine cross beam of leading sheave under each, the last leading sheave of the opposite side that every winch is relative with it respectively, following leading sheave, the fixed pulley group is by the steel rope winding, the suspension hook group that the fixed pulley group is fixed together and is formed by single stay hook by the steel rope winding, axle connects a lifting hook on each stay hook, the number of suspension hook group is identical with the number of fixed pulley group, and adjacent suspension hook group is fixed together.
In order further to realize purpose of the present invention, can form by 3-8 platform winch.
In order further to realize purpose of the present invention, can be that the pulley number of composition fixed pulley group is identical with the number of forming suspension hook group stay hook.
In order further to realize purpose of the present invention, can be that the pulley and the suspension hook group stay hook of fixed pulley group is 2-10.
In order further to realize purpose of the present invention, can be that described lifting hook is that hook is connected and composed by the above equalizing bar axle of two-stage, the top of afterbody equalizing bar is provided with one and connects axis hole, other grades equalizing bar is provided with the connection axis hole that three triangles distribute, the base angle of higher level's equalizing bar two connections axis hole is connected the axis hole axle with the drift angle place of subordinate's equalizing bar respectively and links together, and connects a suspension hook on the base angle of afterbody equalizing bar respectively.
In order further to realize purpose of the present invention, can be that described equalizing bar is the 2-6 level.
In order further to realize purpose of the present invention, can be that described suspension hook is the circular grapple of lower opening.
In order further to realize purpose of the present invention, can be that fixed pulley group and suspension hook group are the 2-8 group.
Compared with the prior art the present invention has following distinguishing feature and good effect: jack up unit of the present invention adopts 3 above winchs, every winch respectively by steel rope successively with upper and lower leading sheave, fixed pulley group, suspension hook group winding, be connected with a suspension hook on each stay hook of suspension hook group, increased the tonnage that hoists like this, just with fixed pulley group and suspension hook group, increase suspension centre simultaneously, disperseed the gravity that hoists, make erecting equipment stressed evenly, more safe and reliable; Hook is to be connected and composed by the above equalizing bar axle of two-stage, and every grade of equalizing bar is connected with two equalizing bar axles of next stage respectively, and whole lifting power is distributed on each equalizing bar, has disperseed the suffered power of suspension hook like this, and is more safe and reliable; Two base angles of afterbody equalizing bar axle respectively connect a suspension hook, evenly spread on four suspension hooks each group suspension hook stressed littler with single hook is stressed, the area of thrust surface of lifting beam and suspended object have been strengthened simultaneously, make stressed more even, safe, better reliability; Suspension hook is the circular grapple of lower opening, gib can be inserted in the annulus of suspension hook like this, and the pipe link of gib stretches out with suspended object from the suspension hook opening part and is connected, like this with the stressed dispersion of suspension hook, the suspension centre of suspended object is increased, and area of thrust surface increase simultaneously, and suspended object can not sustained damage.
