挺杠式力矩限制器在塔式起重机上的应用及浅议

本文就目前塔式起重机普遍采用的电子式力矩限制器的弓形（机械式）力矩限制器的使用性能,工作机理和理论推导上存在的问题,提出了较为灵敏,准确,工作性能可靠的挺杠式力矩限制器。通过对其结构设计、工作原理的论述,建立受载变形公式,分析其参数间的关系。它的应用是提高力矩限制器技术性能的又一种途径。

Application of Rod Type Moment Limiter on Tower Crane and a Primary Discussion

On the basis of the performance, operating mechanism and theoretic derivation of existing electronic and bow type (mechanical) moment limiters broadly used in tower cranes, a more sensible, accurate and reliable rod type moment limiter is presented in this paper. Through discussion of the structure design and operating principle, the equation of deformation under load is established and the relationship between parameters is analyzed. The application of the new limiter is an alternate approach to improve the performance of moment limiters.
