Double-layer telescopic lifting platform
The invention discloses a double-layer telescopic lifting platform, which belongs to the technical field of stage structures and comprises an upper-layer platform, a lower-layer platform and a lifting platform, the upper-layer platform is provided with an upper platform surface and a plurality of upright posts, the bottom of the upper platform surface is fixedly connected with the tops of the upright posts, and the upright posts are connected with first ends of chains at positions close to the bottom; the lower-layer table is provided with a lower table top and a plurality of fixing frames, the number of the fixing frames is the same as that of the stand columns, the fixing frames are fixed to the lower table top, chain wheels are fixed to the fixing frames, and the chains are meshed with the chain wheels; the jacking mechanism is arranged below the lower table top and comprises a rigid chain and a power piece which are in transmission connection; the fixed position of the second end of the chain in the vertical direction is lower than the chain wheel, the power piece drives the rigid chain to jack the lower-layer table, and the chain and the chain wheel are matched to drive the upper-layer table to ascend relative to the lower-layer table. The jacking mechanism can meet the lifting requirement within a short lifting stroke, and then the depth of a needed foundation pit can be reduced.
本发明公开一种双层伸缩升降台，属于舞台结构技术领域，包括：上层台，设置有上台面与多个立柱，上台面的底部与多个立柱的顶部固定连接，立柱在靠近底部的位置连接链条的第一端；下层台，设置有下台面与多个固定架，固定架的数量与立柱的数量相同，固定架固定于下台面，固定架固定有链轮，链条与链轮啮合；顶升机构，置于下台面的下方，包括传动连接的刚性链与动力件；链条的第二端在竖直方向的固定位置低于链轮，动力件驱动刚性链顶升下层台，链条与链轮配合带动上层台相对于下层台上升。本发明可以使顶升机构在较短的提升行程内满足升降要求，进而可以减小所需基坑的深度。
