升降舞台随滑块在滑道中移动而升降，设计要求滑块移动距离相同时，两组平台升降距离相同，因此在设计时要做好平行度控制。

1、由于设计要求升降舞台http://www.iyunsun.com/90个单元闭合高度为恒定值，因而设计工装共4件，放在大平台的四个角，大平台放在工装上后就能够保证大平台在同一高度。很多情况下，上轴承座和大平台有间隙，此时调整油缸活塞杆，使某一轴承座和大平台之间无间隙，如有间隙时垫入合适厚度钢板，轴承座和大平台焊接牢固。
Due to the design requirements for the lifting stage 90 units closed height is a constant value, thus a total of four tooling design, on the four corners, a large platform on a large platform after tooling to ensure a large platform at the same height. In many cases, the bearing and a large platform with a gap, then adjust the cylinder piston rod, so that no gap between the bearing and a large platform, pad into the appropriate thickness steel plate if clearances,bearing housings and a large platform welding firm.

2、上滑道安装是确保升降舞台在升降过程中满足大平台平行度的关键，根据机构设计原理，上、下轴承座和下滑道固定的情况下，如果上、下滑道不平行，厚钢板点处上滑道和大平台有间隙。
The slide installation is key to ensuring a large platform parallelism landing stage to meet the lifting process, according to mechanism design theory, on the case of a fixed bearing and glideslope, if on the glide path is not parallel,the thick steel plate at the point slides and a large platform with a gap.

3、升降舞台http://www.iyunsun.com/用行车吊在大平台重心点，平稳升至最大净升高度，测量大平台4个角的高度，确保4个角升高距离在允差范围内，此时上滑道和大平台间隙垫入合适厚度钢板，上滑道和大平台焊接牢固。
Landing stage hung a large platform with a driving focus point, steady rise to a maximum net lifting height, height measuring large platform four corners, four corners to ensure increased distance is within the tolerance range, this

time on a slide and a large gap between the pad into a suitable platform the thickness of the steel, the slide and a large platform welding firm.
