大开口吊盘稳固装置的布局与控制

Layout and Control of the Stable Device on Large Opening Hanging Scaffold

针对深井大开口吊盘因稳绳张紧力的增大而导致传统的插梁式或轮胎式稳固装置对吊盘变形与失稳不利的问题,依据吊盘梁受力分析,提出了轮胎式稳固装置沿吊盘梁双向对称布置的优化方案。针对稳固装置运动不同步,产生盘面偏心易造成剐蹭吊挂管路、操控困难的问题,设计了一套简单、有效、可行性强,适用于不同生产工况的液压传动控制方案。最后,对单侧布置和双侧布置的轮胎稳固装置布置方案进行了ANSYS分析及对比,结果表明双向对称布置方案可显著改善吊盘梁受力,值得推广。

In this paper, according to the analysis of the lifting force of the suspension beam, the problem that the traditional beam . type or tire . type stabilizer is unfavorable to the deformation and instability of the hanging plate due to the increase of the tension force of the stability rope in the large.scale carousel of the deep well. An optimized plan for the symmetrical arrangement of the two.way suspension girders. For the problem that the movement of the stable device is not synchronized, the eccentricity of the disk surface is easy to cause the hanging pipe and the control is difficult, a set of hydraulic transmission control scheme that is simple, effective, and feasible is applied to different production conditions.Finally,using ANSYS analysis and the comparison of the tire stabilizer arrangement schemes with single . sided arrangement and double . sided arrangement are carried out. The result shows that two.way symmetrical arrangement can improve the force of the disk and beam significantly.It is considered to be worth promoting.
