Description

The anti-steel cable winding system that waves lifting mechanism of four-point hoisting three-point balancing
Technical field
The present invention relates to the hoisting crane field of mechanical technique, particularly relate to the anti-steel cable winding system that waves lifting mechanism of a kind of four-point hoisting three-point balancing.
Background technology:
Lifting mechanism is that any hoisting crane is prerequisite, makes article obtain the basic composition of dipping and heaving.The quality of lifting mechanism work will directly affect the serviceability of whole hoisting crane.The wire rope roll system for winding is the pith of the driving system of lifting mechanism, is comprised of flexible member (steel rope or chain), guiding and storage element (pulley and reel).It will rotatablely move and change over straight-line motion, play the conversion of mode of motion and the transfer function of energy.In the prior art, wirerope-winding mechanism mainly contains following several:
1, two suspension centres lifting form, as shown in Figure 1, it adopts the double crosslinking drum of two common coaxial arrangement, and the rope of two inboards is directly introduced suspender, the rope in two outsides is introduced suspender after by coaxial arrangement and the deflection sheave parallel with drum shaft again, is hinged on the suspender with the rope of two inboards.This version only has the oblique pull of a direction, therefore can only control the horizontal pendulum power of a direction, rocks seriously so wave in the process of lifting cargo operation and rotation, service efficiency is low, dangerous large, the work that is only applicable to is not frequent, the low and less demanding occasion of efficient.
2, four-point lifting lifting form, as shown in Figure 2, it uses 6 reels in rectangular layout, lower 8 ropes are the mode that four inverted-triangulars are arranged, be specially: adopt the double crosslinking drum of two coaxial arrangement, rope of two inboards is directly introduced suspender on it, forms the oblique pull of a direction.The rope in two outsides is introduced suspender after by coaxial arrangement and the deflection sheave parallel with the double crosslinking drum axle again, is hinged on the suspender with the rope correspondence of two inboards, and its forms the oblique pull with inboard rope relative direction.Bilateral symmetry at double crosslinking drum arranges four perpendicular to the simply connected reel of its axis, and is synchronous for keeping they and double crosslinking drum, and by bevel gear and double crosslinking drum locking, suspender is directly introduced in their rope stretchings separately, and is hinged on the suspender relatively in twos.Formed the hyperstatic structure of 4 same suspenders that hoist, each suspension centre all is an inverted triangle, has controlled the swing of suspender in horizontal surface.The static determinacy model of mechanics is, determines planes at 3, and there are four suspension centres on a plane, by 8 rope carryings, certainly will form unbalance stress again.And the reel of control rope is many again, and the Light Difference of processing and fabrication and installation all can cause the steel rope unbalance stress, causes at last some steel ropes fragile.Therefore, this version complex structure, parts are various, and manufacturability is required height, and manufacture difficulty is large, and uses the on site maintenance difficulty.
Fig. 3 is existing popular freight container 8 rope winding systems, is in the structural improvement of Fig. 2, and it uses the special reel of two coaxial arrangement, and each reel need go out four ropes.Two ropes in the middle of each reel form the oblique pull of a direction respectively by hinged with the corresponding introducing of drum shaft four deflection sheavies parallel and that be distributed in reel both sides suspender.Two ropes in each reel outside are first respectively by approaching the deflection sheave that is level, and corresponding respectively more corresponding rope is hinged on the suspender together by introducing respectively suspender behind the vertically arranged deflection sheave, and it forms the oblique pull of another direction.Finally become the hyperstatic structure of 4 same suspenders that hoist, each suspension centre all is an inverted triangle, has controlled the swing of suspender in horizontal surface.Although it is two multi-joint special reels that this version reel is simplified, but deflection sheave has been increased to 12 by 2, so many pulleys are the numerous and diverse space three-dimensional layout in space, lower 8 ropes are four inverted-triangulars at last, although performance can guarantee, but steel rope turns to fatiguability and unbalance stress through repeatedly multidirectional, and service life is low.Pulley arrangements is in disorder, and the fall line that steel rope plane on dolly is crisscross makes and makes and fabrication properties requirement height, and cost is large.
Summary of the invention:
The object of the invention is to overcome the defective of above-mentioned prior art, provide a kind of and prevent that effectively suspender from swinging in the space, structure is simple and direct, parts are arranged neat, making and mounting process require low, steel rope is stressed, and evenly system is firm, the anti-steel cable winding system that waves lifting mechanism of the four-point hoisting three-point balancing of long service life.
The technical scheme of taking for achieving the above object is:
The anti-steel cable winding system that waves lifting mechanism of a kind of four-point hoisting three-point balancing, it is characterized in that: it is parallel with the double crosslinking drum axis and be arranged symmetrically in the deflection sheave of both sides that the double crosslinking drum, four that comprises two coaxial arrangement is arranged on movable pulley on the suspender of double crosslinking drum below and eight average two rows of one-tenth, draw 4 ropes on the described double crosslinking drum, every rope all by one of them movable pulley and with two adjacent deflection sheavies of this movable pulley homonymy setting after be fixed on the suspender.
Above-mentioned four movable pulleys are distributed on the suspender symmetrically, suspender be arranged in double crosslinking drum under.
Above-mentioned eight deflection sheavies are divided into two rows, and are parallel to spool axis and are distributed in the reel both sides.
Above-mentioned wherein two of the centres of row's deflection sheave connect with balancing device.
The present invention is on the double crosslinking drum of two common coaxial arrangement, lower four ropes, arrange with it 8 deflection sheavies of parallel rule layout by two, realize 8 inverted-triangulars of four positive triangle stacks (there is positive triangle of two inverted triangle stacks on each plane), both guaranteed the rigidity of suspension fully, prevent that effectively suspender from waving, and compound with regular structure is succinct.And wherein a row has two adjacent deflection sheavies to fix with equalizer bar, has also realized the principle of four-point hoisting three-point balancing, and actv. has been controlled when the lift heavy deflection, the problem of steel rope unbalance stress.Whole lifting mechanism structure is clean and tidy, easily makes processing, and steel rope is stressed evenly, and improve service life, uses the field maintemance expense few.Reel adopts common double crosslinking drum, makes supporting all low with tooling cost.8 pulleys are two of Parallel Symmetric arranges and puts, and simple in structurely understands the processing and manufacturing function admirable.The lifting mechanism multiplying power can increase, and has reserved the space for the raising hoisting capacity, also can make same rising under the liter weight, and wirerope diameter is little, can make corresponding parts all little, reduces cost, energy savings, and thin steel cable flexible is good, and service life is better.
