剪叉式高空作业平台是通过举升油缸推动剪叉机构升降的形式将工作平台和作业人员送至所需高度的机器。为保障作业人员安全和提升整机的平稳性,准确得出油缸在举升时所需的推力尤为重要。文中通过分析油缸举升时克服重力势能及摩擦做功等因素的影响,并应用能量守恒等原理,得到了油缸压力与滑块摩擦的关系。最后通过试验验证及理论计算对比分析,进一步证实了结论的正确性。因此,该方法对于剪叉高空作业平台液压系统的设计具有积极意义。

The scissor aerial work platform is a machine that transports the work platform and the operators to the required height by lifting the scissor mechanism through the lifting hydraulic cylinder. In order to ensure the safety of operators and improve the stability of the whole machine, it is particularly important to accurately obtain the thrust required by the hydraulic cylinder during lifting. By analyzing the influence of factors such as gravitational potential energy and frictional work when the hydraulic cylinder is lifted, and applying the law of conservation of energy, the relationship between the hydraulic cylinder pressure and the friction of the slider is obtained. Finally, experimental verification and comparative analysis of theoretical calculations further confirm the correctness of the conclusions. Therefore, this method has positive significance for the design of the hydraulic system of the scissor aerial work platform.
