The invention relates to the technical field of elevator engineering, discloses a movable car assembly of a gear and rack elevator, and aims to solve the problem that emergency braking of a car causes impact damage to safety parts and prevent the car from being directly locked after complete stall on the basis of existing braking. The driving gear is driven by the driving motor to move on the guide rack, so that the lift car moves up and down, when the lift car stalls to generate the phenomena of top rushing and rapid descending, the limiting shaft enters the limiting sleeve due to inertia, and the limiting shaft is forced to continuously extend into the limiting sleeve through transmission between the brake tooth row and the driving gear, so that the lift car is driven to move up and down. Due to the fact that the friction force between the limiting shaft and the limiting sleeve is increased due to the increase of the insertion depth, the lift car is relatively stable during braking, and finally the stable and safe braking effect is achieved.
本申请涉及电梯工程技术领域,公开了一种齿轮齿条提升机的移动轿厢组件,为了解决轿厢紧急刹车对安全部件造成冲击损坏的问题,在现有制动的基础之上,为了防止轿厢在完全失速后被直接抱死,通过驱动电机带动驱动齿轮在导向齿条上活动,实现轿厢上下移动,当轿厢出现失速而产生冲顶和速降现象时,限动轴会受惯性进入限动套中,并通过刹车齿排和驱动齿轮之间传动,迫使限动轴不断的伸入至限动套中,由于限动轴和限动套之间因插入深度的增大而摩擦力增大,从而使得轿厢刹停时相对平稳,最终实现了平稳安全制动的效果。
