Description
Technical field
The utility model belongs to hoisting machinery field, and in particular to a kind of drift angle of cable crane steel wire rope zero enters the volume of groove
Cylinder automatic arranging rope lifting mechanism.
Background technology
Cable crane is mainly used in large hydropower station engineering construction, is the very high and more special lifting of use intensity
Machine, usual cable machine hoist rope from reel lay out after by the leading block on vehicle frame, to being suspended on carrying rope
Dolly leading block, further around to suspension hook, small pulley sheave then consolidate, see Fig. 1.Cable machine steel wire rope lays out reel and moves into guiding
Pulley drift angle refers to steel wire rope center line and the angle β and steel wire rope and leading block axle vertical plane of reel spiral groove center line
Angle α, is shown in Fig. 2.
Cable machine hoisting system has following distinguishing feature：
1）For the working cable machine of Hydropower Project, more than complete machine working level A7, with speed of service height, using strong
The characteristics of spending big.Although reel sail angle β is passed in and out in GB3811 regulation steel wire ropes not should be greater than 3.50, steel wire rope lays out pulley
Drift angle α not should be greater than 50, but use experience have shown that, drift angle is very big on the influence of the service life of cable machine steel wire rope, in identical fortune
Under row operating mode, when drift angle is more than 1.50When, than 00Drift angle service life of steel wire rope declines more than 30%, therefore steel wire during design of cable crane
The drift angle value of rope is generally less than 10, groove mode is generally entered using zero drift angle, far above standard regulation.
2）It is arranged in river valley area more cable machine, is often in the more severe position of geology, landform, therefore cable machine is set
Timing is bound to take into full account and pays close attention to size of the cable machine perpendicular to river direction, and reducing cable machine basic platform width b, (Fig. 1 shows
Meaning), this not only contributes to reduce the cost of equipment in itself, and civil engineering difficulty and investment, particularly side slope can be greatly decreased
During steeper, slope excavating can also affect on greatly stability of the hill influence safety.Therefore the width dimensions b of cable-crane platform is cable
An important indicator in machine design, is also to embody one of major parameter of design of cable crane level, design of cable crane person is always grinding
Study carefully and reduce the size.
According to the above-mentioned two feature of cable machine, current cable machine arranges as follows using two ways in the design：
1）Mode one, directly winds, sees that Fig. 1 modes 1 are illustrated.Directly winding is simplest mode, but requires reel
It is larger apart from a to leading block, it is in practical application and few due to geology, the limitation of orographic condition.
2）Mode two, carries out row's rope using special rope-arranging mechanism, realizes that zero drift angle enters groove, see that Fig. 1 modes 2 are illustrated.
The construction for the rope-arranging mechanism that present cable machine is used is substantially similar with arrangement, reference can be made to following utility model is special
Profit：A kind of rope guide of cable machine lifting mechanism, application number CN200420060658.3；Notification number CN2727133, it is used specially
Although the rope-arranging mechanism of door solves the problems, such as deflection angle of rope, can also change the rope outlet direction of steel wire rope（Rope outlet direction and volume
Cylinder diameter parallel）, but there is also certain following not enough：
1）During using rope-arranging mechanism, hoisting drum axis is parallel with rope outlet direction, because hoisting drum is along axis side
To much bigger than the size of circumferencial direction of size, it is flat using the arrangement cable machine of rope-arranging mechanism compared with directly arranging
The excavation width b of platform can be much larger, as shown in Figure 1, needs the imagination for reducing berm width mutually to conflict when this is with design of cable crane.
The precipitous engineering of some side slopes, is arranged so as to use because the limitation of address landform is denied.
2）Rope-arranging mechanism construction is complicated, and manufacture purchase cost is high, high to matching requirements, and rope-arranging mechanism is typically set
Put below reel, install and regular maintenance is relatively difficult, the inspection of some parts and replacing consumable accessory more trouble are, it is necessary to specially
With instrument and shutdown long period.
The utility model is the brand-new imagination under the application-specific requirement for cable machine, can realize that the drift angle of steel wire rope zero enters
Groove, can solve to arrange the deficiency of rope using rope-arranging mechanism, with beneficial technique effect again.
