The main effect of elevator cage door locking device is to guarantee that elevator is when hoistway, gate can not be opened, to guarantee occupant's safety, present gate locking device generally adopts electromagnetic type gate lock and link-type gate lock, wherein, electromagnetic type gate lock needs to produce effect by the coil adhesive, needs to adopt electrical control; Because there is Problem of Failure in electric element, therefore there is certain risk, such as power supply outage in a single day, electric system will lose efficacy, therefore the reliability of electromagnetic type gate lock is not as mechanical type gate lock, and the related action face of mechanical link-type gate lock is bigger, thus its compactedness exist not enough, the safety performance instability.

The utility model content

The purpose of this utility model is a kind of compact conformation that designs for the deficiency that solves above-mentioned technology, the elevator cage door locking device that safety performance is stable.

The elevator cage door locking device that the utility model is designed, comprise the main latch hook and the secondary latch hook that cooperatively interact, in secondary latch hook, be provided with contact assembly, described main latch hook comprises latch hook; rocking arm and latch hook base plate; latch hook is movably connected on the latch hook base plate; slide block assembly is arranged fixedly also on the latch hook base plate; the quarter butt on the rocking arm and the intersection of stock are movably connected on the slide block assembly; and rocking arm is located at the top of latch hook; on the stock end of rocking arm roller is arranged fixedly; the wheel face of this roller is fitted and is placed on the tail end of latch hook, fixedly hits wheel on the quarter butt of rocking arm, is provided with the contact that cooperatively interacts with contact assembly at the tapered end of latch hook.

When gate during at hoistway, the pinning that cooperatively interacts of the latch hook of main latch hook and secondary latch hook; When layer door reaches flat bed, be installed in hitting bow and hitting wheel and contact on the layer door; rocking arm is that fulcrum is to angle of right rotation with quarter butt and stock intersection; thus rocking arm passes through downward application force of tail end of pair of rollers latch hook; and tapered end is upturned; by driving main latch hook with secondary latch hook and separating, the gate of elevator is opened at last.

For can main latch hook is spacing in certain position, play spacing effect, fixedly there is caging bolt on top at secondary latch hook, this caging bolt is located at the corresponding position of slide block assembly, also be with rubber block on the bolt cap of caging bolt, this rubber block is fitted with the slide block of slide block assembly in the gate closed condition.

For elevator cage door closes or opens more convenient, improve practicality, slide block assembly comprises guide rod, slide block and spring, slide block and spring all are enclosed within on the guide rod, one end of spring is conflicted on slide block, the other end is conflicted on the block of latch hook base plate, and the two ends of described guide rod are by on the block that is bolted to the latch hook base plate.

The elevator cage door locking device that the utility model is designed, compact conformation, safe and reliable, stable performance, practicality height.
