Abstract

The utility mode discloses mechanical equipment, in particular to a rope-breaking and rope-winding prevention device of a bridge-type crane. The rope-breaking and rope-winding prevention device of the bridge-type crane comprises a coiling block, a steel wire rope head fixing device, a trolley frame, a reducer, a breaker, a coupler, a motor and steel wire ropes, wherein one ends of the steel wire ropes are connected with the winding block and then wind a movable pulley set and a fixed pulley set in sequence, and the other ends of the steel wire ropes are fixed on the steel wire rope head fixing device. The rope-breaking and rope-winding prevention device of the bridge-type crane has the advantages that the steel wire ropes respectively penetrate through the movable pulley set and the fixed pulley set, and then a crossed winding system is formed. Reasonable arrangements of the fixed pulley set enable the steel wire ropes not to be interfered in the process of crossed winding. The modified rope-breaking and rope-winding prevention device of the bridge-type crane can relay on the other rope to support the whole lifting hook pulley sets and can not lose balance nor fall off under the condition that one of the ropes is broken, and heavy articles can be placed on the ground slowly through a winch. The rope-breaking and rope-winding prevention device of the bridge-type crane can be widely used in places such as power stations and factories.

Description

A kind of crane in bridge type anti-break rope rope winding device
Technical field
The utility model relates to a kind of mechanical equipment, refers in particular to a kind of crane in bridge type anti-break rope rope winding device.
Technical background
In the last few years, along with large nuclear power station, power station and thermal power plant put into operation, the power station core component is (such as the stator of generator set, rotor, hydroturbine rotor etc.) single-piece weight is near kiloton, single-piece is worth and also becomes present several ten million yuan even more than one hundred million unit from original millions of units, the rated load weight of bridge machine, span and lifting altitude are also in continuous increase, especially present newly-built large nuclear power station, safety to large part lifting is paid attention to especially, in case have an accident, its negative effect is very huge, safety and fault-tolerance when these all impel the user to large of bridge machine handling are had higher requirement, and traditional baudrier more and more shows its drawback:
The first, along with the increase of hoisting capacity and lifting altitude, the multiplying power of assembly pulley is also along with increasing, and steel rope also is thicker longer, and the degree of wear of steel rope is in aggravation, and the probability of damage is also along with increase.
The second, traditional baudrier is if there is the fracture of steel rope, and suspension hook is with run-off the straight or fall, and may cause falling of handling article, causes great loss.
The utility model content
This practicality has proposed a kind of new design plan for the deficiency on the traditional wiring system that occurs, and actv. has solved the problem of above-mentioned existence.
The utility model is achieved by following technical proposals:
A kind of crane in bridge type anti-break rope rope winding device, it comprises reel, the fixed pulley group, steel wire rope head fixture mechanism, trolley frame, retarder, drg, coupler, electrical motor, running block, steel rope, it is characterized in that: steel rope one end is connected with reel, walks around successively running block, fixed pulley group again, and the other end of steel rope is fixed in steel wire rope head fixture mechanism.
As preferably, the fixed pulley group in above-mentioned a kind of crane in bridge type anti-break rope rope winding device comprises left side fixed pulley group, right side fixed pulley group; Running block comprises left side running block, right side running block; Steel rope one end is walked around left side running block, left side fixed pulley group, right side running block, right side fixed pulley group more successively with after reel is connected, and the other end of steel rope is fixed in steel wire rope head fixture mechanism.
As preferably, steel rope forms by two, two steel ropes are walked around respectively the different pulleys in same fixed pulley group or the running block, and the pulley quantity of every group of fixed pulley group that every steel rope is walked around is identical, is identical with this power of guaranteeing two steel ropes that every group of running block is subject to.
In the utility model, two steel ropes are reeled respectively according to technique scheme and are formed, and have formed the wiring system of intersecting, and arrange by the dislocation of fixed pulley group, can be so that steel rope can mutually noninterfere when cross winding.
Beneficial effect:
The power that every steel rope is applied owing to every group of running block is equally large, and the safety factor of steel rope generally is more than 4 times, therefore after the therein steel cable fracture, another root steel rope can keep the balance of suspension hook fully and can not fall, and can operation hoists and traveling gear slowly drops to weight on the ground by continuing; The utility model is by the position adjustment of fixed pulley group is realized, substantially do not have to increase with respect to the work capacity of traditional baudrier device fabrication cost and wire rope handling, but the safety during bridge machine handling weight has increased significantly.

The specific embodiment
Below in conjunction with accompanying drawing, enforcement of the present utility model is specified.
Embodiment 1
Such as structure among accompanying drawing 1, Fig. 2, Fig. 3, a kind of crane in bridge type anti-break rope rope winding device comprises reel 1, steel wire rope head fixture mechanism 3, trolley frame 4, retarder 5, drg 6, coupler 7, electrical motor 8, (10, wherein steel rope 10 1 ends are connected with reel 1 steel rope, walk around successively running block 2, fixed pulley group 9, the other end of steel rope 10 is fixed in steel wire rope head fixture mechanism 3 again.Through the crane in bridge type anti-break rope rope winding device that changed, therein in the situation of steel cable fracture, can support whole lifting hook pulley group by another root steel rope and be unlikely to unbalance or fall, guarantee that weight can operation hoists and traveling gear puts it to ground slowly by continuing.
Embodiment 2
Such as Fig. 1, shown in Figure 4, a kind of crane in bridge type anti-break rope rope winding device comprises reel 1, steel wire rope head fixture mechanism 3, trolley frame 4, retarder 5, drg 6, coupler 7, electrical motor 8, steel rope 10, wherein steel rope 10 1 ends are connected with reel 1, and fixed pulley group 2 wherein comprises left side fixed pulley group, right side fixed pulley group; Running block 9 comprises left side running block, right side running block; Steel rope 10 1 ends are walked around left side running block, left side fixed pulley group, right side running block, right side fixed pulley group more successively with after reel 1 is connected, and the other end of steel rope 10 is fixed in steel wire rope head fixture mechanism 3.And steel rope wherein 10, fixed pulley group 2, running block 9 are respectively two groups, so more be conducive to safety in the work progress etc., and owing to being that two groups of steel ropes 10 have been divided into two groups, namely such as the steel rope 10-1 among Fig. 4 and steel rope 10-2, can effectively play the effect of strengthening intensity.
