Anti-falling-back limiting jack for magnetic suspension track beam positioning
The invention discloses an anti-falling-back limiting jack for magnetic suspension track beam positioning. A jack cylinder, an output shaft arranged in the jack cylinder in a sliding manner and a movable limiting structure arranged on the output shaft are included. The anti-falling-back limiting jack has the beneficial effects that according to the scheme, after the output shaft of the jack adjusts a track beam in place through stretching and contracting, the limiting structure is utilized for locking the output shaft of the jack for limiting, output shaft contraction caused by the action of counter thrust exerted on the output shaft through the track beam is avoided, and accordingly track beam position stability and track beam positioning accuracy are guaranteed.
本发明公开了一种用于磁悬浮轨道梁定位的防回落限位千斤顶，包括千斤顶缸体、滑动设置在千斤顶缸体内的输出轴和设置在输出轴上且可移动的限位结构。本发明的有益效果是：本方案当千斤顶的输出轴通过伸缩将轨道梁调整到位之后，利用限位结构将千斤顶的输出轴锁定以限位，从而避免在轨道梁对输出轴施加的反推力的作用下而导致出输出轴回缩，从而保证轨道梁位置稳定以及轨道梁的定位精度。
