Abstract
The utility model relates to a safe elevator door leaf, include by elevator door leaf frame and attach the door leaf body that the steel sheet on elevator door leaf frame constitutes, characterized by: the on -edge edge of the door leaf body is opened along door leaf body direction of height has an elongated slot, is equipped with upper and lower slide rail at the upper and lower edge of elevator door leaf frame, is equipped with on upper and lower slide rail and follows the gliding spring holder of upper and lower slide rail, and evenly distributed has the spring on the spring holder, and the spring is connected with a movable door plank, and movable door plank stretches out in following the elongated slot that the door leaf personally experienced sth. Part of the body, is connected with the pull rod at the rear portion of spring holder. Its advantage is: can not press from both sides the passenger tightly, make the passenger receive the injury, the passenger the elevator for the incasement both hands just can open certain space with the door leaf, in case there is the passenger to strand at the elevator incasement, can save oneself, the situation that leads to the fact the passenger to suffocate because of elevator incasement air is not enough can not take place.
Description
Technical field
The utility model relates to a kind of emergency staircase door leaf, belongs to elevator door field.
Background technology
Existing elevator mainly contains rotating ladder and box elevator two class, and most widely used is box elevator.Box elevator mainly comprises elevator case, driving system and control system, the elevator door leaf that two fans are split is separately installed with on elevator case and on the gangway of elevator, when elevator case runs to the elevator gangway of specifying, on the elevator door leaf on elevator case and elevator gangway, elevator door leaf synchronously opens or cuts out.Existing elevator door leaf is made up of elevator door leaf framework and the steel plate be attached on elevator door leaf framework, and the stile up and down of elevator door leaf is provided with the guide rail that can slide in the chute of elevator chamber door frame or elevator doorway doorframe.Existing box elevator setting has multiple safe protection device; as: when the improper landing of elevator case, driving system is provided with anti-slip locking mechanism, above elevator chamber door frame, is provided with infrared probe, elevator door leaf is provided with anti-pinch induction installation and is provided with weight induction device etc. on elevator case.Although existing box elevator is provided with maltilevel security safety method, but still can there are some safety misadventures, be mainly reflected in: the anti-pinch induction installation 1, on elevator door leaf is malfunctioning, when passenger does not also enter elevator case completely, elevator door leaf cuts out, and clamped by human body, now elevator brings into operation, not only likely people is crushed, even people is dragged extremely; 2, the improper landing of elevator case, and stop between floors, now the control system of elevator is completely malfunctioning, and elevator door leaf closes, and elevator door leaf cannot be opened from interior by the passenger in elevator case, also cannot save oneself, can only wait for external rescue.Due to narrow space in elevator case, elevator door leaf is closed tight in addition, and air deficiency in elevator case, passenger are nervous, if can not be rescued in time, passenger can be caused to suffocate or individual passengers cardiac trigger onste, consequence is hardly imaginable.
Summary of the invention
The purpose of this utility model is to provide a kind of passenger can not to be clamped and passenger with the hands just can open the emergency staircase door leaf in certain space in elevator case.
The utility model provides technical scheme as follows:
The utility model comprises by elevator door leaf framework and is attached to the door leaf body that the steel plate on elevator door leaf framework forms, it is characterized in that: the edge-on limit of door leaf body has an elongated slot along door leaf height direction, the upper and lower limit of elevator door leaf framework is provided with upper and lower slide rail, upper and lower slide rail is provided with the spring perch that can slide along upper and lower slide rail, spring perch is evenly distributed with spring, spring is connected with a movable doorboard, movable doorboard stretches out from the elongated slot of door leaf body, is connected with pull bar at the rear portion of spring perch.
The utility model has the advantages that: passenger can not be clamped, passenger is come to harm; Door leaf with the hands just can be opened certain space by passenger in elevator case, once there be passenger to be trapped in elevator case, can save oneself, the situation because air deficiency in elevator case causes passenger to suffocate can not occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
With reference to accompanying drawing, the utility model comprises by elevator door leaf framework 1 and is attached to the door leaf body that the steel plate 2 on elevator door leaf framework forms, the edge-on limit of door leaf body has an elongated slot along door leaf height direction, upper at elevator door leaf framework, be provided with slide rail 4 and glidepath 8 below, upper slide rail and glidepath are provided with can along on the spring perch 5 that slides of slide rail and glidepath, spring perch is evenly distributed with spring 6, spring is connected with a movable doorboard 7, the edge of movable doorboard is circular arc, movable doorboard stretches out from the elongated slot of door leaf body, pull bar 3 is connected with at the rear portion of spring perch, upper at door leaf body, be provided with door leaf slide rail 9 below.
During application, door leaf body is connected by the drive motor of transmission device with elevator door leaf, and spring perch is connected with linear electric motors by pull bar.When elevator door leaf is opened, the drive motor synchronized operation of linear electric motors and elevator door leaf, pulls back spring perch, and spring perch drives movable doorboard to be reduced in door leaf body by spring; When elevator door leaf closes, the drive motor synchronized operation of linear electric motors and elevator door leaf, by spring perch driven forward, releases movable doorboard from door leaf body, until the movable doorboard of two relative elevator door leafs contacts, completes the closed of elevator door leaf.When the anti-pinch induction installation on elevator door leaf is malfunctioning human body is clamped time, because movable doorboard is promoted by spring, what human body can not be pressed from both sides is too tight, and movable doorboard with the hands just can be pushed open to both sides by people, saves oneself; When the improper landing of elevator case; and when stopping between floors; movable doorboard with the hands just can be pushed in door leaf body to both sides by passenger in elevator case; open certain space; make in elevator case, there is sufficient air; meanwhile, if when the height of the gangway of positional distance elevator that stops of elevator case is very little, passenger also can climb out of elevator case voluntarily.
