高精度轨道调节锁紧机构设计

针对拖曳水池高精度轨道的调节锁紧问题,对轨道调节范围、轨道直线度和水平度调节机构以及调节支座的固定3个方面进行了研究。运用三维设计软件CREO2.0,建立了斜块式调节锁紧机构及分离式调节锁紧机构的三维模型。基于建立的三维实体模型,对以上两种调节锁紧机构的工作原理进行了说明。通过对横向和垂向调节范围、横向调节锁紧力、垂向调节锁紧力及锚固进行理论分析,提出了在高精度、高速度和动载荷轨道设计施工中宜采用分离式调节锁紧机构,而不宜采用斜块式调节锁紧机构。实际应用结果表明,分离式调节锁紧机构在轨道精度、轨道稳定性、后期维护等方面均优于传统的斜块式调节锁紧机构。

Design of high precision track adjusting locking mechanism

Aiming at adjusting locking mechanism of high precision track of towing tank,the rail adjustment,the rail straightness,the adjustable levelness mechanism and the fixation of adjustable bearing were studied.Using the 3D design software CREO2.0,the model of the adjustable inclined block type lock mechanism and the detached adjustable lock mechanism was built.Based on the solid model,the working principles of the above two mechanisms were described.Through the theoretical analysis of the horizontal and vertical adjustment range,locking force and anchorage,it was put forward that the detached adjustable lock mechanism used in the high precision,high speed and dynamic lock rail design construction,but not adaptable for adjustable inclined block type lock mechanism.Practical application results show that the detached adjustable lock mechanism is superior to the traditional inclined block type lock mechanism in the aspects of the track accuracy,the stability of the track and the later maintenance.
