Abstract
The utility model provides an electromagnetic door knife, relating to structural improvement of a door knife of an elevator. The electromagnetic door knife solves the safety hazard caused by a traditional door knife which is nonretractable and eliminates the defect that the traditional door knife has noise. The electromagnetic door knife is composed of an electromagnetic door knife mounting seat, an electromagnet, a spring, a connecting rod, a swing stem and a door knife. The electromagnetic door knife has the advantage that when the elevator works normally, the door knife can retract and has no collision with a door lock or a door wheel, so the door lock can be opened; when the elevator stops working, the door knife resets to home position and collides with the door lock, the door lock can only be opened at this time, the electromagnetic door knife eliminates the safety hazard of the elevator, raises the service efficiency of the elevator, decreases the noise and prolongs the service life of the elevator.
Description
Technical field: the invention relates to the improvement of elevator door knife structure.
Background technology: on the existing at home dumb waiter, the all not flexibles of door cutter, when the upper and lower operation of elevator, every layer always has the feasible door of an end regions (district of promptly an opening the door) cutter collision machine door lock trolley, and mechanical door lock is subjected to the collision of a cutter in this section zone, all be in open mode, at this moment, hoistway door artificially or owing to door lock collides the vibration that produces is opened probably, and this situation has reduced the service efficiency of elevator, has brought potential safety hazard simultaneously.
Summary of the invention: the purpose of the invention provides a kind of safe in operation, the Electromagnetic door knife that service efficiency is high; The purpose of the invention is achieved through the following technical solutions; Electromagnetic door knife, comprise a cutter, it is characterized in that constituting by Electromagnetic door knife mount pad, electromagnet, connecting rod, fork, door cutter, spring, electromagnet is installed on the Electromagnetic door knife mount pad, pocketed springs on the electromagnet telescopic shaft, connecting rod one end is installed on the electromagnet telescopic shaft, and the other end is connected with the door cutter, fork one end is installed on the Electromagnetic door knife mount pad, and the other end is connected with the door cutter.
The advantage of the invention: the elevator run duration, the electromagnet energising of elevator Electromagnetic door knife, electromagnet core shrinks and drives telescopic shaft contraction compression spring pulling connecting rod, make the four-bar linkage swing that constitutes by fork and door cutter, the door cutter produces contractive action, is in contraction state all the time, and Electromagnetic door knife does not collide door lock, make mechanical door lock to be opened, only after elevator is out of service, the electromagnet dead electricity, electromagnet core stretches out under action of the spring, a cutter is resetted, and door lock just is opened.The zone of opening the door when having eliminated the elevator operation has ensured that elevator is safe in utilization; Electromagnetic door knife trolley of locking of collision gate not in running process of elevator has been eliminated the door cutter collision noise that trolley produced; Prolonged mechanical door lock service life simultaneously.
Description of drawings:
Fig. 1 is the Electromagnetic door knife structural representation;
Fig. 2 is an A-A sectional drawing among Fig. 1.
The specific embodiment: Electromagnetic door knife is by Electromagnetic door knife mount pad 7, electromagnet 1, connecting rod 3, fork 5,6, door cutter 4, spring 2 constitutes, electromagnet 1 is installed on the Electromagnetic door knife mount pad 7, pocketed springs 2 on the electromagnet telescopic shaft, connecting rod 3 one ends are connected with electromagnet 1 telescopic shaft, the other end is connected with door cutter 4, fork 5,6 one ends are fixed on the Electromagnetic door knife mount pad 7, and the other end is connected with door cutter 4, constitutes four-bar linkage, when elevator normally moves, electromagnet 1 drives 4 translations of door cutter and shrinks, and when elevator was out of service, the door cutter resetted, the collision gate wheel of locking a door, door lock just can be opened.
