Abstract

A retractable elevator vane comprises a vane body arranged above a car door. An automatic retractable mechanism arranged between the vane body and the car door includes a fixed iron core and a movable iron core, wherein the fixed iron core is mounted on the car door, and the movable iron core is fixed to the vane. A return spring is arranged between the fixed iron core and the movable iron core. An electromagnetic coil is mounted on the fixed iron core; and the vane mounted on the car door is retractable. When the door opens or closes on an elevator stop floor, the vane extends out and is inserted into a hoistway door ball, so that a hoistway door is driven to open or close. When an elevator runs, the vane retracts, collision of the vane and a hoistway door sill and collision of the elevator vane with the door ball caused by shake in high-speed running of the elevator car are prevented, the gap between the hoistway door sill and a car door sill can be reduced, and safety is ensured.

Description

Elevator retractable door cutter

Technical field

The utility model relates to a kind of van-type elevator, particularly a kind of elevator retractable door cutter.

Background technology

The elevator switch door is the gate by the driving elevator of door motor, and the door motor of elevator is contained in the gate top, and a cutter is equipped with in the switching of control gate on gate, and gate is the active door, and Room door is a passive door, is fixed with croquet on the door of the Room.When elevator stopped layer, the door cutter penetrated croquet, outwards opened when gate like this, when the drive metal frame is outwards opened, just promoted croquet and outwards opened, and croquet and Room door are fixed, and croquet is outwards opened, and then drives Room door and outwards opens.Otherwise in like manner.

During normal the use door cutter insertion croquet degree of depth as 5mm about, the gap of lading door dill and car door sill is fixed according to croquet and the outstanding distance of door cutter, the door cutter is not collided to lading door dill when guaranteeing that elevator moves up and down, will guarantee also that simultaneously Room door outstanding croquet and car door sill do not collide.A cutter and lading door dill are collided for rocking of producing when the elevator cage high-speed cruising or the elevator door cutter hits croquet, brings potential safety hazard.

Summary of the invention

The technical problems to be solved in the utility model is at the deficiencies in the prior art, a kind of elevator retractable door cutter has been proposed, prevent because rocking of producing during the elevator cage high-speed cruising collided a cutter and lading door dill and the elevator door cutter hits croquet, can also reduce simultaneously the gap between lading door dill and the car door sill, guarantee safety.

The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of elevator retractable door cutter, be characterized in: comprise the door cutter body that is located on the gate, be provided with automatic telescoping mechanism between door cutter body and the gate, described automatic telescoping mechanism comprises static iron core that is contained on the gate and the moving iron core of fixing with door cutter body, be provided with retracing spring between static iron core and the moving iron core, magnet coil is housed on the static iron core.

The utility model compared with prior art, a door cutter that is installed on the gate stretches, and stops layer at elevator and drives at closing time a door cutter and stretch out, and inserts Room every ball, drives Room door open and close.The withdrawal of elevator when operation door cutter prevents from can also reduce the gap between lading door dill and the car door sill simultaneously, assurance safety because rocking of producing during the elevator cage high-speed cruising collided a cutter and lading door dill and the elevator door cutter hits croquet.

Description of drawings

Fig. 1 is the structure diagram of retractable door cutter.

Fig. 2 is running condition figure of the present utility model.

The specific embodiment

A kind of elevator retractable door cutter, comprise the door cutter body 1 that is located at the gate top, be provided with automatic telescoping mechanism between door cutter body 1 and the gate 9, described automatic telescoping mechanism comprises static iron core 3 that is contained on the gate and the moving iron core of fixing with door cutter body 12, be provided with retracing spring 5 between static iron core 3 and the moving iron core 2, magnet coil 4 is housed on the static iron core 3.

The elevator switch door is the gate 9 by the driving elevator of door motor, the door motor of elevator is contained in gate 9 tops, and the switching of control gate is equipped with a cutter 1(and is resembled cutter because of shape on gate 9, the cutter so call at the door), the gate 9 and the Room door 7 of elevator separate, and gate 9 is active doors, and Room door 7 is passive doors, be fixed with the thing of croquet 8(on the Room door 7 as ball, there are two on the general Room door, have living space in the middle of two croquets, be used for wearing a cutter).Iron core adhesive when elevator moves up and down, door cutter retraction, dead electricity when elevator stops layer, a door cutter servo-actuated iron core stretches out under the effect of spring, thus the croquet that inserts Room door drives Room door switch.Prevent that the while can also reduce the gap between lading door dill 6 and the car door sill 10 because rocking of producing during the elevator cage high-speed cruising collided a cutter and lading door dill and the elevator door cutter hits croquet.

Claims

1. elevator retractable door cutter, it is characterized in that: comprise the door cutter body that is located on the gate, be provided with automatic telescoping mechanism between door cutter body and the gate, described automatic telescoping mechanism comprises static iron core that is contained on the gate and the moving iron core of fixing with door cutter body, be provided with retracing spring between static iron core and the moving iron core, magnet coil is housed on the static iron core.
