Description
Technical field
The present invention relates to stage machinery technical field, more specifically to a kind of elevator of stage.
Background technology
At present, the special elevator of stage be it is a kind of special install before the lights, applied to video system presentation facility or
The lifting of stage equipment (such as stage property equipment, suspension rod equipment, wall, audiovisual frame and stage boards etc.), to reach in performance
When can more dazzle it is beautiful excellent.
And the elevator of the existing stage of in the market is straight using motor generally by the tight stage equipment of steel wire rope bolt
Connect lifting or decline, to realize the lifting or suspension of stage equipment.However, there are many deficiencies in the structure of this elevator
Place：
1st, elevator function is single, it is impossible to move in the horizontal direction, therefore stage equipment also can not be by elevator towards many
Direction is lifted, do not only result in in-convenience in use, and need artificial operation movement, substantially reduce operating efficiency.
2nd, when elevator works, skew can be produced by being wrapped in the rope stretching point position of steel wire rope on elevator, due to conventional lift
The pulley that the angle pulley that machine is used is fixed for direction, thus wire rope displacement angle it is larger when, steel wire rope easily deviates from race, very
Popped up to because of inertia so as to depart from elevator, so can not only influence the stability of lifting, and cause easily to trigger thing
Therefore, substantially reduce the security performance of elevator.
Mechanical wear is big when the 3rd, using, service life is short, is mainly reflected in：It is not provided with corresponding self-locking, mechanical position limitation
With the protection device such as travel switch, stage equipment is easily caused in lifting process and is damaged.
The content of the invention
It is an object of the invention to overcome shortcoming and deficiency of the prior art, there is provided a kind of stage of excellent performance
Elevator；The elevator of the stage can not only realize the lifting of stage equipment, but also can realize that the level of stage equipment is moved
It is dynamic, so that applied widely；Meanwhile, the elevator improving stability is good and safety coefficient is high, is conducive to stage machinery industry
Use and promote.
In order to achieve the above object, the technical scheme is that：A kind of elevator of stage, is used
In moving and lift to stage equipment；It is characterized in that：The dolly that is moved including track, along track and it is separately positioned on
If the roller for being wound with steel wire rope on dolly, for driving drive device that roller rotates, for avoiding the de- rope of steel wire rope
Dry universal rope guide and several positioning pulleys for lifting stage equipment；Support body, roller are provided with the dolly
