Description
Technical field
The present invention relates to stage machinery technical field, more particularly, relate to a kind of gig of stage.
Background technology
At present, the special gig of stage is a kind of to install before the lights specially, being applied to the lifting of video system presentation facility or stage equipment (such as stage property equipment, suspension rod equipment, wall, audiovisual frame and stage boards etc.), can more dazzling beautiful excellence to reach when performing.
And the gig of existing stage is generally utilize electrical motor directly promote or decline by the tight stage equipment of steel rope bolt on market, realize lifting or the suspension of stage equipment.But there is a lot of weak point in the structure of this gig:
1, gig function singleness, cannot move in the horizontal direction, and therefore stage equipment also cannot be promoted towards multi-aspect by gig, not only causes using inconvenience, and needs manual operation to move, and greatly reduces work efficiency.
2, during gig work, the rope stretching point position being wrapped in steel rope on gig can produce skew, the deflection sheave adopted due to conventional lift machine is the pulley that direction is fixed, therefore when wire rope displacement angle is larger, steel rope easily deviates from race, even because inertia pops up thus depart from gig, so not only can affect the stability of lifting, and cause easily accidents caused, greatly reduce the safety performance of gig.
When 3, using, mechanical wear is large, service life is short, is mainly reflected in: do not arrange the fender guards such as corresponding self-locking, mechanical position limitation and travel switch, easily cause stage equipment impaired in lifting process.
Summary of the invention
The object of the invention is to overcome shortcoming of the prior art with not enough, a kind of gig of stage of excellent performance is provided; The gig of this stage not only can realize the lifting of stage equipment, but also can realize the parallel motion of stage equipment, thus applied widely; Meanwhile, this gig improving stability is good and safety factor is high, is conducive to using and promoting of stage machinery industry.
