Description

Lifting device for stage Technical Field The utility model belongs to the technical field of stage lifting, and particularly relates to a lifting device for a stage. Background Currently, when an actor leaves or performs, the actor is slowly lifted from a stage through a lifting platform arranged on the stage, so that the effect of leaving the scene is improved. The lifting operation of the lifting platform is usually performed by adopting a lifting device. However, the existing lifting device can only realize basic lifting function, lacks effective protection measures for the actor lifted to the high position, is extremely easy to fall down to the stage due to instability when the actor is lifted to a higher and dangerous position, causes serious injury, and has obvious potential safety hazard. Disclosure of utility model The utility model provides a lifting device for a stage, which aims to solve the technical problem that an actor is easy to be seriously injured due to falling down of the stage due to lack of high-position safety protection measures in the prior lifting device for the stage. The utility model discloses a lifting device for a stage, which comprises a stage body, a mounting cavity arranged on the stage body, an annular shell arranged in the mounting cavity, a supporting plate fixedly arranged at the top of the annular shell, a lifting table used for lifting an actor and arranged above the supporting plate, and a protection mechanism assembled on the supporting plate and used for protecting the actor. Preferably, the protection mechanism comprises an electric telescopic rod fixedly arranged at the bottom of the supporting plate, a supporting block fixedly arranged on an output rod of the electric telescopic rod, and a transparent protection cover sleeved on the lifting table in a sliding manner, wherein the inner wall of the transparent protection cover is fixedly connected with the supporting block, and the transparent protection cover is positioned in the opening. Preferably, the lifting device for the stage further comprises a height adjusting mechanism installed in the installation cavity for lifting the support plate. Preferably, the height adjusting mechanism comprises a screw rod rotatably arranged on the inner wall of the bottom of the installation cavity, a sleeve is arranged on the screw rod in a threaded manner, the top end of the sleeve is fixedly connected with the supporting plate, a double-shaft motor fixedly arranged on the inner wall of the bottom of the installation cavity, a first conical gear is fixedly sleeved on an output shaft of the double-shaft motor, a second conical gear is fixedly sleeved on the screw rod, and the second conical gear is meshed with the first conical gear. Preferably, the lifting device for the stage further comprises a rotating mechanism which is arranged on the supporting plate and used for rotating the lifting platform, the rotating mechanism comprises a shell fixedly arranged on the supporting plate, a speed reducing motor is fixedly arranged on the inner wall of the shell, and an output shaft of the speed reducing motor is fixedly connected with the bottom of the lifting platform. Preferably, the top of backup pad has seted up the recess, be provided with the ball in the recess, the ball with the bottom of elevating platform contacts. Preferably, the top fixed mounting of elevating platform has arc climbers, the inner wall fixed mounting of installation cavity has the gag lever post, slidable mounting has the limiting plate on the gag lever post, one side of limiting plate with annular shell fixed connection. Compared with the related art, the stage lifting device provided by the utility model has the following beneficial effects: Through the use of protection machanism in this scheme, can rise the high time of comparatively dangerous to the actor at the elevating platform, rise the eminence with transparent safety cover, make the top of transparent safety cover can be higher than the elevating platform, make it can form the transparent protection barrier that encircles the actor gradually, can prevent effectively that the actor from falling down the stage because of unstability in the performance process, can improve the security of actor's performance at the eminence greatly, effectively solved current stage elevating gear because of lacking the high-altitude safety protection measure, lead to the actor to be easy to cause serious injured technical problem because of falling down the stage.
