Description

Elevator car door locking device

Technical field

The utility model relates to the locking device technical field of control turnover elevator cab door.

Background technology

For guaranteeing the safe operation of elevator, the safety device that control turnover elevator cab door is set is necessary, particularly seem particularly important during greater than 0.15m when the distance between elevator hoistways inside face and the car sill, in these cases, when elevator and when out of service not in leveling zone et out of order or power failure, passenger in the lift car can open car door voluntarily and escape, but also do not know car is in what position passenger's this moment, because above-mentioned distance, can passenger's pin (leg) portion be damaged, more dangerous is: when elevator faults recovers or incoming call again, car door door-closing in-place malfunctioning switch, at this moment elevator can restart operation and causes bigger personal injury even bring life danger to the passenger; Someone proposes to add rigidity and nonflammable divider wall is eliminated above-mentioned distance at the hoistway inside face; More than or equal to 3 and open the door when big, just time-consuming, cost is high and easily cause elevator installation period to prolong at elevator floor stops in this measure.

Summary of the invention

The purpose of this utility model is in order to address the above problem, a kind of elevator car door locking device to be provided, with control turnover elevator cab door; This cage door lock device is had no effect to the normal run switch door of elevator, and when elevator in leveling zone et out of order or power failure and when out of service, the passenger can open car door voluntarily and escapes in the car; And when elevator not in leveling zone et out of order or power failure and when out of service, the passenger then can't open gate and go out; Can utilize this moment in the sedan-chair warning device to report to the police, wait for professional's rescue, because during Lift out of order, the passenger stays and waits in the sedan-chair that it is safest rescuing.

For achieving the above object, the technical solution of the utility model is such: a kind of elevator car door locking device comprises the hanging hook assembly that is fixed on the door opener cross girder, is fixed on the stopper board component on the machine link plate and is fixed on and hitting bow three assemblies on layer door gear; Said hanging hook assembly by adapter plate, connecting rod, link up with, bump wheel, spring and electric switch and form, wherein pass through rod hinge connection between hook and the adapter plate, it can translation and rotation among a small circle, connect one on the connecting rod and bump wheel, this bumps wheel and is between car door sill line and the landing sill line, its with hit bow and can contact connection, drivening rod moves during collision, spring is installed on the hook afterbody, and electric switch is installed in hook head portions; Said stopper board component is made up of stopper plate, the switch contact and the set screw of fixing on it, it is with door machine link plate horizontal motion in the scope of opening the door, switch contact just distributes, but connect with the contact electricity of electric switch contact, set screw is fixed on the stopper plate, and be between stopper plate and the hook, with spacing; Said hitting bent on the layer door gear that is arranged on each layer.

Working process of the present utility model is such: when car door is closed the door near the position, set screw on the stopper board component promotes the hanging hook assembly door-closing in-place after hitting bow and bumping wheel to throw off a segment distance that moves in the same way, the spring of hook afterbody has certain precompressed amount, in this process, hook rotates and the stopper plate forms on interlocking and the hook electric switch and switch contact formation electric loop are given control system with signal, and this moment, elevator can normally move; After elevator arrives the purpose stop, door opener drives gate and opens, in the gate opening process, hanging hook assembly is run into the fixed bow that hits on layer door gear at the wheel that bumps that moves in the same way above it with the stopper board component under the promotion of spring force, at this moment hanging hook assembly stops translation, rotate under the effect of spring force and make hanging hook assembly and the unhook of stopper board component, gate can drive layer door smoothly and open.

Owing to adopted technique scheme, a kind of elevator car door locking device of the present utility model has machinery and electric double interlocking, when out of service, can guarantee passenger's safety when Lift out of order or power failure; Hanging hook assembly rotates after hitting bow and breaks off relations running under the effect of spring force, and it is in translation and the rotation in week of little model, avoided hitting bow and hanging hook assembly move back and forth other mechanical part of grazing possibility and also increased mechanical and electric reliability; Two contacts of electric switch adopt the height structure in addition, make volume of switch little, thin thickness, and Installation and Debugging are convenient.

Description of drawings

Below in conjunction with drawings and Examples the utility model is described in detail.
