[0002] With the continuous development of economy, people's material living standards are gradually improving, and entertainment and cultural life are becoming more colorful. More and more people choose to watch stage performances during business hours, so the requirements for stage effects are getting higher and higher. In stage performances, lifting devices are often needed to simulate some special scenes, such as earthquakes or explosions.

[0003] Most of the existing lifting devices simulate the existing elevator structure, and lift the elevator car in a fixed elevator shaft through a pulley group, a traction rope and a counterweight, such as the elevator device disclosed in the application number TW20120117172. Due to structural limitations, the existing lifting devices can only be used to perform up and down vibrations in the vertical direction when applied to stage performance scenes, and the expressiveness cannot meet the needs of stage performances and film and television production. Therefore, it is necessary to design a lifting device that can swing in different directions. Summary of the invention

[0008] Furthermore, the elevator car has one or more floors.

[0009] Furthermore, when the elevator car rises to the maximum height, the height of the standing surface in the elevator car on one layer connected to the lifting frame is consistent with the height of the stage steps.

[0010] Furthermore, support feet are provided at the bottom of the lifting frame; when the elevator car is not rising, the support feet stand on the bottom surface of the guide frame.

[0011] Furthermore, a light source irradiating upward is installed in the lifting frame, and the angle of the light beam irradiating the elevator car upward is 7 degrees.

[0012] Furthermore, the height of the guide frame is greater than the height of the elevator base, so that the swing driving device can drive the guide frame to swing and sway in the swing frame.

[0013] Furthermore, the lifting drive device includes a driving pulley driven by a motor and a plurality of driven pulleys, and the driving pulley and the plurality of driven pulleys are connected by a traction rope.

[0014] Furthermore, a counterweight is provided on the traction rope.

[0015] The present invention has the following advantages and positive effects:

[0016] 1. The present invention uses a swing driving device to swing the guide frame so that the guide frame swings within the range of the swing frame, thereby driving the elevator car installed in the guide frame to swing.

[0017] 2. The swing frame of the present invention is connected to the fixed seat via a first universal joint assembly, and is connected to the guide frame via a second universal joint assembly, which not only defines the swing base point of the guide frame but also ensures its swing freedom.

[0018] 3. The elevator car of the present invention rises from the foundation pit to the stage, and the swing drive device swings it at the bottom of the foundation pit. The lifting drive device is also arranged in the foundation pit. No major large-scale drive device can be seen on the stage, and the stage effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
