The specific embodiment
If Fig. 1 is to as shown in Fig. 4, elevator door knife of the present invention and movable light curtain linkage comprise a set of elevator door vane device, a set of movable elevator light curtain assembly, a set of cutter connecting rod mechanism.
According to door cutter moveable arm position difference, can be divided into two kinds of embodiments, when door cutter moveable arm during in left side connecting rod mechanism be interlock bar linkage structure, as shown in Figure 1, 2; When door cutter moveable arm during on right side link gear be rigid rod structure, as shown in Figure 3,4.
By certain device, above-mentioned door cutter is driven, when elevator door is just opened, moveable arm 2 meeting gripping layer every balls 3 of elevator door knife, when elevator door cuts out soon, the moveable arm 2 of elevator door knife can be decontroled layer every ball 3, and above-mentioned a series of actions has guaranteed that layer door is with gate synchronous opening/closing.
Above-mentioned movable light curtain 4 is embedded in safety edge, and safety edge main body is fixed on gate 1 by the light curtain connecting rod mechanism 5 and 9 at its back.The fulcrum of four groups of connecting rod mechanisms 5,9,13,14 is fixed on gate 1.The upper end of connecting rod 5, connecting rod 13 is connected with safety edge is hinged, and the lower end of connecting rod mechanism 5 contacts with electric switch 8 with rubber roll 7, and the lower end of leverage 13 is connected with gate by spring; The upper end of leverage 9,14 is connected with safety edge is hinged, and 9 lower end is connected with gate 1 by spring, and 14 lower end contacts with electric switch 8 with rubber roll 7.
The door cutter connecting rod mechanism of above-mentioned connection elevator door knife and movable light curtain, different according to door cutter moveable arm position, can be formed by an interlock connecting rod 6 or a rigid rod 11.
Be interlock bar linkage structure as shown in Figure 1, 2, the fulcrum of interlock connecting rod 6 is fixed on gate 1, the moveable arm 2 of an end dotted or gate cutter of interlock connecting rod 6 is by higher pair 12 sliding block joints, the stroke of its slip is limited according to connecting rod rotational travel, another end points of door cutter connecting rod is by the lower end in contact of rubber roll 7 and electric switch 8 and light curtain connecting rod 5, and rubber roll 7 and electric switch 8 are installed on the bottom of interlock connecting rod 6.
Be rigid rod structure as shown in Figure 3,4, rigid rod 11 one end are fixing with the moveable arm 2 of door cutter, and the other end is by the lower end in contact of rubber roll 7 and electric switch 8 and light curtain connecting rod 5, and the connection mode of other positions is with interlock bar linkage structure.
During installation, need guarantee layer every ball 3 with the mechanism of its underpart not at same vertical surface, in order to avoid elevator layer every ball 3 and its underpart mechanism interference that bumps while moving up and down.
According to above-mentioned a series of connection, can realize following functions: as shown in Figure 2,4, when elevator door is just opened, door cutter moveable arm 2 gripping layer every balls 3, door cutter drives movable light curtain 4 motions simultaneously, due to movable light curtain 4 gravitates, cause movable light curtain 4 to stretch out cutter door-plate 1 edge; As shown in Figure 1,3, when elevator door cuts out soon, door cutter moveable arm 2 is decontroled layer every ball 3, door cutter drives movable light curtain 4 motions simultaneously, the safety edge of the movable light curtain 4 of compressing parcel is contracted in door-plate 1 edge, thereby guarantees that the safety edge that door is closed on rear two sidelight curtains can not interfere with each other; As shown in Figure 5, in the time of in the process of door in closing the door, if people or thing are encountered safety edge 4, safety edge 4 is done fine rotation around the connecting rod mechanism 5,9,13 and 14 at its back, be contracted in door-plate 1, contact on the electric switch 8 at its back disconnects simultaneously, thereby people or the thing between door detected.
The present invention is not limited to embodiment discussed above.Above the description of the specific embodiment is intended in order to describe and illustrate the technical scheme the present invention relates to.Apparent conversion based on the present invention enlightenment or substitute and also should be considered to fall into protection scope of the present invention.The above specific embodiment is used for disclosing best implementation method of the present invention, so that those of ordinary skill in the art can apply numerous embodiments of the present invention and multiple alternative reaches object of the present invention.
