The invention relates to the technical field of elevators, in particular to an elevator car mechanical protection device and an elevator. The device comprises a first locking piece and a driving assembly. The first locking piece has a first state and a second state; when the first locking piece is in the first state, the first locking piece can limit the relative position of the elevator car and the landing door sill; when the first locking piece is in the second state, the first locking piece does not limit the relative position of the elevator car and the landing door sill; the driving assembly is in linkage fit with the elevator car door and used for driving the first locking piece to be switched between the first state and the second state. When the elevator car door is opened, the first locking piece is in the first state, and serious safety accidents can be reduced or avoided. And after the elevator car door is completely closed, the first locking piece is in the second state, and the elevator car recovers normal operation. The device can not be influenced by short circuit of a safety circuit, the safety and reliability of an elevator door system are improved, and the elevator using safety of passengers is guaranteed and protected.
本发明涉及电梯技术领域,具体涉及一种电梯轿厢机械保护装置及电梯。该装置包括第一锁定件和驱动组件;第一锁定件具有第一状态和第二状态;第一锁定件处于第一状态时,第一锁定件能够限制电梯轿厢与厅门地坎的相对位置;第一锁定件处于第二状态时,第一锁定件不限制电梯轿厢与厅门地坎的相对位置;驱动组件与电梯轿门联动配合,用于驱动第一锁定件在第一状态和第二状态之间切换。当电梯轿门开门后,第一锁定件处于第一状态,能够减少或避免严重安全事故的发生。当电梯轿门完全关闭后,第一锁定件处于第二状态,电梯轿厢恢复正常运行。该装置可不受安全回路是否短接的影响,提升电梯门系统的安全性和可靠性,保障保护乘客的用梯安全。
