Further, steel cable is equipped with four, and every two steel cables, which are curled up respectively with same direction, is fixed on a roller two sides.

Further, pulley is fixed on cage top by pulley seat, in two column settings.

Further, pulley is equipped with 4 or 8.

Further, mounting base includes fixed part and interconnecting piece, and fixed part is fixed among crossbeam, and interconnecting piece is in inverted triangle Channel steel type, bottom apex pass through the swingable connection in vertex of pin shaft and triangle equalizer bar.

Further, two endpoints of triangle equalizer bar are equipped with the steady device of adjusting rope, and two endpoints of triangle equalizer bar are logical Overregulate the steady device connection steel cable of rope.

The invention has the following beneficial effects:

Four rope cage balance device structures of the invention are simple, easy to use, can automatically adjust in cage operational process Cage balance, realizes vertical even running, guarantees personnel and cargo security in cage, practical.

Detailed description of the invention

In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with It obtains other drawings based on these drawings.

Fig. 1 is the structural schematic diagram of four ropes cage balancing device provided by the invention；

Fig. 2 is the enlarged drawing of A in Fig. 1；

Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

As shown in Figure 1-3, four rope cage balancing devices of the invention, including base 1,1 top surface of base are equipped with bracket 2 and electricity Machine 3, bracket 2 is interior to be arranged two reels 4, and motor 3 connects two reels 4 by two-way retarder 31, and two reels 4 are by motor 3 Power is provided to be rotated.1 bottom surface both side of base is equipped with crossbeam 11, is equipped with mounting base 5, the bottom point of mounting base 5 among crossbeam 11 By the swingable connection in vertex of pin shaft 6 and triangle equalizer bar 7, two endpoints of triangle equalizer bar 7 pass through steel cable 8 respectively and hang The pulley 91 on 9 top of cage connects, and the other end of two steel cables 8 is curled up respectively on two reels 4.

Steel cable 8 is equipped with four, and every two steel cables 8, which are curled up respectively with same direction, is fixed on 4 two sides of reel, and two Steel cable 8 on reel 4 curls up contrary.It is connected to not by swingable be connected in mounting base 5 of triangle equalizer bar 7 to adjust With the length of the steel cable 8 on reel 4, keep 8 length of steel cable identical.

Pulley 91 is fixed on 9 top of cage by 91 pedestal of pulley, in two column settings.When 9 volume of cage or load-carrying are smaller When, 91 settable 4, pulley, each column is arranged 2, i.e., every steel cable 8 passes through 1 pulley 91 and connect with cage 9, and one end connects One endpoint of 4 other end of reel connection triangle equalizer bar 7.When 9 volume of cage or larger load-carrying, pulley 91 is arranged 4 or 8 A, each column is arranged 4, i.e. every steel cable 8 passes through 2 pulleys 91 and connect with cage 9, and one end connection 4 other end of reel connection One endpoint of triangle equalizer bar 7.

Mounting base 5 includes fixed part 51 and interconnecting piece 52, and fixed part 51 is fixed among crossbeam 11, and interconnecting piece 52 is in three Chamfered groove steel type, bottom apex pass through the swingable connection in vertex of pin shaft 6 and triangle equalizer bar 7.Two endpoints of triangle equalizer bar 7 It is equipped with the steady device 71 of adjusting rope, two endpoints of triangle equalizer bar 7 connect steel cable 8 by adjusting steady device 71 of restricting.

In 9 operational process of cage, four steel cables 8 are worked at the same time, it is ensured that when wherein a steel cable 8 is broken, in addition Steel cable 8 can also safe elevator cage 9, prevent cage 9 from falling, and keep cage 9 balance even running；When one of reel 4 When error, which occurs, in the running causes two steel cables 8 different in size, steel cable 8 is adjusted by the swing inclination of triangle equalizer bar 7 Length, until 8 length of steel cable is identical, triangle equalizer bar 7 is stopped action, and prevents cage 9 from tilting, and keep its balance.Triangle Equalizer bar 7 is all belonged to the scope of protection of the present invention regardless of the top of 2 bottom of bracket or cage 9 in base 1.

In conclusion four rope cage balance device structures of the invention are simple, and it is easy to use, it can be in cage operational process Cage balance is automatically adjusted, realizes vertical even running, guarantees personnel and cargo security in cage, it is practical.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
