Abstract
The utility model relates to a goods lift door installs bistable trigger device additional, characterized by include left door, right door, elevator door switch controller, bistable trigger switch, bistable controller, bistable trigger, pilot lamp, elevator door switch controller signal input part is connected to bistable trigger switch's control signal output part, elevator door switch controller control elevator door switch, and bistable controller is connected to bistable trigger switch's bistable signal output part, and bistable trigger installs in the outside 1cm department that left door and right door all opened the position, bistable trigger and pilot lamp electric connection. The advantages are that: the probability of damaging the left door and the right door is greatly reduced; the crushing proportion of the glass inside due to door collision is reduced. Due to the reminding of the indicator light and the alarm, the door collision accident caused by unclear information transmission is almost reduced to zero.
Description
Technical Field
The utility model relates to a goods lift door installs bistable trigger device additional belongs to elevator safety control technical field.
Background
In the prior art, when a freight elevator is stopped stably, an operator opens a manual switch of an elevator door, an elevator door switch controller starts to work, the elevator is opened towards two sides, and when a left door and a right door are completely opened in place, the operator shouts a forklift driver and tells that the freight elevator can be sent to the elevator. This operation has several disadvantages: (1) when the left door or the right door is not completely opened to the end, an operator may call a forklift driver without noticing the operator, and the forklift driver easily bumps the left door or the right door; (2) operators and forklift drivers are easy to operate mistakenly because mutual shouting is not clear; it is highly desirable to find a method to overcome the above-mentioned drawbacks.
SUMMERY OF THE UTILITY MODEL
The utility model provides a goods lift door installs bistable trigger device additional, its aim at to the defect that prior art exists, through structural design, but a greatly reduced makes the goods lift door of the broken proportion of glass of the inside install bistable trigger device additional because of hitting the door is proposed.
The technical solution of the utility model is as follows:
bistable trigger device is installed additional to goods lift door, including left door 1, right door 2, elevator door switch controller, bistable trigger switch 5, bistable controller 6, bistable trigger 7, pilot lamp 8, the control signal output part of bistable trigger switch 5 connects elevator door switch controller signal input part, and elevator door switch controller control elevator door switch, bistable signal output part connection bistable controller 6 of bistable trigger switch 5, and bistable trigger 7 installs in the outside 1cm department of the whole open position of left door 1 and right door 2, bistable trigger 7 and pilot lamp 8 electric connection.
Still include alarm and infrared inductor, infrared inductor signal output part connects alarm signal input part, bistable trigger and alarm, infrared inductor electric connection. Before the elevator door is not completely opened in place, if the infrared sensor senses the movement of the forklift, the alarm gives an alarm sound.
The utility model has the advantages that:
(1) the probability of damaging the left door and the right door by collision is greatly reduced; the crushing proportion of the glass inside due to door collision is reduced.
(2) And due to the reminding of 8 indicator lamps and an alarm, the door collision accident caused by unclear information transmission is almost reduced to zero.
Drawings
Fig. 1 is a structural schematic diagram of a cargo lift door with a bistable trigger device.
In the figure, 1 is a left door, 2 is a right door, 5 is a bistable trigger switch, 6 is a bistable controller, 7 is a bistable trigger, and 8 is an indicator light.
Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings.
Referring to the attached drawing 1, when the goods elevator is stopped stably, an operator opens the door and the switch of the bistable trigger, the door and the bistable controller start to work, the left door and the right door of the elevator are opened towards two sides, the bistable trigger starts to work at the same time, when the left door and the right door are all opened in place, namely 1cm away from the bistable trigger, the switch-on indicator light is lightened, and when a forklift driver sees that the 8 indicator light is lightened, the goods is delivered into the elevator.
The bistable trigger switch is provided with two control circuits, wherein one control circuit is connected to a door opening/closing controller, and the other control circuit is connected to the bistable controller; the bistable trigger needs to switch on the indicator light to light when the distance between the left door and the right door is 1cm, and turn off the alarm; the position of the indicator light is easy to see for the forklift driver.
