The invention relates to the technical field of airport ground equipment, in particular to a gear locking center pillar lifting mechanism, center pillar mechanical locking in the gear locking center pillar lifting mechanism can respond to any position along with lifting of a center pillar, analog quantity distance feedback signals are adopted through an encoder, and therefore more accurate rack position measurement and judgment can be achieved; meanwhile, an accurate position can be easily reached for locking through one-key lifting, in addition, when the middle column descends, the oil cylinder is lifted firstly, the pawls are opened and then the middle column descends, direct lifting and random locking can be achieved, in addition, tedious pawl unlocking and locking actions are not needed, the situation that the left pawls, the right pawls and racks are staggered in the locking process does not need to be worried, and the locking effect is good. Therefore, the synchronism of the double lifting racks can be improved, and the technical problems that locking and unlocking actions of an existing pawl are large, the risk of under-machine operation is large, and meanwhile the two sides of a ladder body are uneven due to the fact that teeth are staggered easily due to the fact that the locking time of the pawl is not well controlled are solved.
本发明涉及机场地面设备技术领域,具体涉及一种齿轮锁止中柱举升机构,该齿轮锁止中柱举升机构中的中柱机械锁止可以跟随中柱升降任意位置响应,通过编码器采用模拟量距离反馈信号,从而可以实现更加精确的齿条位置测量判断,同时,也可以通过一键升降轻易达到精确的位置进行锁止,另外,在中柱下降时,先升油缸,等棘爪打开再下降的动作流程,可以直接升降,随意锁止,此外,本发明不用繁琐的棘爪开、合锁动作,不用再担心锁停时左右棘爪和齿条错齿情况,从而可提升双举升齿条的同步性,解决了现有的棘爪的合锁和开锁动作较大,机下操作风险较大,同时,棘爪锁止时间控制不好易形成错齿,导致梯身两侧不平的技术问题。
