Detailed description of the invention
As shown in Fig. 1 to 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.
Can be divided into two kinds of embodiments according to door cutter moveable arm position difference, when door cutter moveable arm is in left side, connecting rod mechanism is interlock bar linkage structure, as shown in Figure 1, 2; When door cutter moveable arm is on right side, link gear is 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 ball 3 of elevator door knife, when elevator door cuts out soon, the moveable arm 2 of elevator door knife can decontrol layer every ball 3, and above-mentioned a series of actions ensure 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 the lower end of 9 is connected with gate 1 by spring, and the lower end of 14 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 made up of 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 joint, its stroke slided is limited according to link rotatable stroke, another end points of door cutter connecting rod passes through 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, the moveable arm 2 of rigid rod 11 one end and door cutter is fixed, and the other end passes through 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 linking bar linkage structure.
Need ensure during installation that the mechanism of layer every ball 3 and its underpart is not at same vertical surface, interferes in order to avoid elevator upper and lower runtime layer every ball 3 and its underpart mechanism collide.
According to above-mentioned a series of connection, following functions can be realized: as shown in Figure 2,4, when elevator door is just opened, door cutter moveable arm 2 gripping layer every ball 3, simultaneously door knife-band is moved movable light curtain 4 and is moved, due to movable light curtain 4 gravitate, movable light curtain 4 is caused 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 decontrols layer every ball 3, simultaneously door knife-band is moved movable light curtain 4 and is moved, the safety edge of the movable light curtain 4 of compressing parcel is contracted in door-plate 1 edge, thus ensures that the safety edge that door is closed on rear two sidelight curtains can not interfere with each other; As shown in Figure 5, when door is in the process of closing the door, if people or thing encounter safety edge 4, the connecting rod mechanism 5,9,13 and 14 of safety edge 4 around its back does fine rotation, be contracted in door-plate 1, contact on the electric switch 8 at simultaneously its back disconnects, thus the people between door or thing detected.
The present invention is not limited to embodiment discussed above.Above the description of detailed description of the invention is intended to describe and the technical scheme that the present invention relates to being described.Based on the present invention enlightenment apparent conversion or substitute also should be considered to fall into protection scope of the present invention.Above detailed description of the invention is used for disclosing best implementation method of the present invention, can apply numerous embodiments of the present invention and multiple alternative to reach object of the present invention to make those of ordinary skill in the art.
