The present invention relates to a door lock device of an elevator applying a direct forced cutting door lock switch and configured to allow the central drive of the hatch door.

The general elevator door is composed of a cage door on the main body side and a hatch door on the elevating floor. In addition, the door lock device is composed of a switch that mechanically locks the door and confirms it electrically.When the elevator main body arrives at the sea floor, the door lock device is automatically engaged with the cage door side of the main body side. Is configured to solve.

However, in the conventional door brake apparatus, since the driving force of the door is transmitted to the upper part of the door as in the first diagram, the door is not smoothly driven and the weight of the door is not applicable.

That is, in the conventional lock apparatus as shown in FIGS. 1 and 2, the door rail 1 has a door lock switch 3, a fixed contact piece 9, and a locking section 4 attached thereto, and a hatch door ( 2) At the upper end, the movable roller 5, the fixed roller 6, the hook 7 and the movable contact piece 10 are installed. Since the conventional lock device and its driving device are both installed and operated on the upper part of the door, there is a large load on the action of receiving the driving force, the opening and closing operation of the door is not smooth, and the weight of the door is not applicable.

The present invention forms a connecting rod on the hook of the door lock device to draw out the conventional problems and draws it to the center of the door and installs a transmission device coupled to the door driving device on the door center to connect the hook connecting rod to the delivery device. It is interlocked together by opening the lock device of the arch door by receiving the driving force of the cage door, and smoothly driving the door by driving the drive device and the transmission device in the center of the door, and opening and closing the heavy door The bar will be described in detail with reference to the accompanying drawings. As shown in FIGS. 3 and 4, the present invention installs only the hook 7 and the movable contact piece 10 on the top of the hatch door 2, and the fixed contact piece 9 is installed on the door rail 1 as it is. .

The movable roller 5 on the top of the hatch door 2 is fixed to a separate lower hook 11, and the fixed roller 6 is fixed to the base 12, and then the lower hook 11 and the base 12 are hatched. Installed in the middle of the door (2), connecting the driving rod 13 between the upper hook (7) and the lower hook (11) and the intermediate shaft (14) (15) of the upper and lower hooks (7) (11) With the center point as the center point, only one direction, that is to be turned upward.

In addition, as shown in FIGS. 6 and 7, the base 16 of the door driving device 18 installed in the cage door 19 has a cam 17 of the door opening / closing drive link K and a movable piece which is moved back and forth by this. (8) is installed, and this drive device 18 is installed on the same position line as the lock drive device installed in the middle of the hatch door 2.

The movable roller 8 of these lock rollers is positioned between the base 16 of the opposite door drive 18 and the movable piece 8 so that the movable roller 8 and the fixed roller 6 of these lock rollers are positioned. (5) (6) and the lower hook 11 to transfer the lifting operation, thereby allowing the lower hook 11 to lift the rod 13 and the upper hook (7).

The present invention as described above is the linkage and the movable piece by the operation of the gim 17 installed at the end of the drive link (K) for opening and closing the cage door and opening and closing the cage door 19 by the driving force of the door driving motor not shown 8) lifts the movable roller 5 on the side while moving in the direction of the arrow in FIG. 6, so that the lower hook 11 lifts the rod 13 and the upper hook 7 to release the locked state.

In addition, since the movable contact piece 10 mounted together with the rise of the upper hook 7 is separated from the two fixed contact pieces 9 divided as shown in FIG. 9, the door lock switch 3 when the door is opened. To force the OFF state directly.

On the other hand, when the door is completely closed and these interlocking forces are released, the upper hook 7 lowers the rod 13 and the lower hook 11 by the return force of the spring supporting the upper hook 7, and then returns. The movable contact piece 10 is to be in contact with the stationary contact piece 9 to turn on the switch so that the door can be completely closed to electrically check that it is in a safe state.

The present invention has a device for driving the upper hook (7) is installed in the center of the hatch door (2) and connected to the upper and lower rods 13 by the drive device of the cage door (19) Since it is intended to smoothly open and close the door and can be applied even when the weight of the door is large, there is an effect that can be safely smelt safely compared to the configuration installed in the prior art.

Claims (1)

In the door of an elevator, the driving force of the door driving motor is transmitted to the cage door 19, and the driving force of the drive unit mounted on the cage door 19 is transmitted to the hatch door 2 so as to be interlocked with each other. The rod 13 connects between the attached upper hook 7 and the lower hook 11 fixed to the center of the door 2, and the movable roller 5 attached to the lower hook 1 and the base 12 An elevator door lock device in which a fixed roller (6) fixed to a door is installed to be located on the side of a movable piece (8) of a door driving device (18) installed at the center of the cage door (19).
