The invention discloses an explosion-proof elevator landing door lock catch assembly. The assembly comprises a PLC control system, a motor, a door machine body and a guide rail transversely and horizontally arranged on the door machine body, and a hanging plate is arranged on the guide rail in a relatively sliding manner. The assembly has the beneficial effects that a second triggering striking rod is matched with a second limiting switch in an inserted and buckled manner and triggers the second limiting switch to transmit an electric signal to a PLC control system, meanwhile, through bucklingof a door hook and an auxiliary hook, a first triggering striking plate rotates along with the door hook and triggers a first limiting switch to transmit an electric signal to the PLC control system,if the two electric signals are landing door closing signals, the PLC control system locks a motor to enable the motor not to rotate, and is matched with a mechanical door hook lock catch structure,so that external personnel cannot push open a landing door, sparks or heat effects cannot be generated in the triggering process of the first limiting switch and the second limiting switch, and the standard of national explosion-proof elevators is met.
本发明公开了一种防爆电梯层门锁扣组件,包括PLC控制系统、电机、门机本体以及横向水平设置在门机本体上的导轨,所述导轨上相对滑动设置有挂板,本发明的有益效果在于:通过第二触发撞杆与第二限位开关插扣配合并触发第二限位开关向PLC控制系统传输电信号,与此同时通过门钩与副钩的扣合,第一触发撞板随门钩转动并触发第一限位开关向PLC控制系统传输电信号,如上述两个电信号为层门关闭信号,PLC控制系统则会锁止电机,使其无法转动,再配合机械式的门钩锁扣结构,外部人员无法将层门扒开扒开,由于第一限位开关和第二限位开关的触发过程中,并不会产生火花或热效应,满足了国家防爆电梯的标准。
