Abstract

(57) [Summary] [Purpose] To prevent the accident of opening the floor door and falling into the hoistway. [Structure] A door rope slack detection device 14 is attached to each floor door 1, 2 and either door rope slack detection device 14 is installed.
When the is activated, the elevator car is preferentially placed on the floor.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an elevator safety device, and more particularly to an elevator safety device suitable for an elevator equipped with a rope-driven floor door.

[0002]

[Prior art]

 The conventional device stops the operation of the elevator immediately upon detecting the rope loosening as described in Japanese Utility Model Publication No. 55-134,481 or, as a reference example, as described in Japanese Utility Model Publication No. 63-4975, It was said that the elevator car would be inductively stopped at the nearest floor.

[0003]

[Problems to be solved by the device]

 By the way, the floor door of the rope drive consists of two doors that open left and right, and it is common to have only one of the doors locked. In this case, the floor where the rope has been detected is relaxed. The door on the anti-lock side of the floor is easily opened by hand. There is a possibility that someone may open the door and fall into the hoistway, which is very dangerous.

An object of the present invention is to provide an elevator safety device capable of preventing a rope from falling into a hoistway from a floor door in which looseness is detected.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to an elevator safety device equipped with a rope loosening detection device for a rope-driven floor door provided on each floor, wherein one of the floor doors is a floor door. When the rope slack detection device is activated, the elevator car is preferentially landed on the floor.

[0006]

[Advantageous Effects] According to the present invention, the car is preferentially landed on the floor where the rope loosening device operates, so that it is possible to prevent an accident in which someone falls into the hoistway from the floor door. it can.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a front view of the floor door as seen from the hoistway side, and FIG. 2 is a flowchart of this safety device.

In FIG. 1, 1 is a lock-side door on each floor, 2 is an anti-lock-side door, 3 is a door hanger, 4 is a door rail, 5 is a door driving rope, 6 is a pulley, and 7 is a rope 5 and a door 1 respectively. 2, a hook device, 9 is a hook roller, 9 is a hook metal fitting, 10 is a hook metal fitting, 11 is an engaging plate for a car side roller not shown, 12 is a hook metal fitting return spring, and a is a pivot point of the hook metal fitting 10. , 13 is a door lock device that engages with the hook metal fitting 10 when the lock side door 1 reaches the closed end, 14 is a door rope loosening detection device, and 141 is a contact for operating the door rope loosening detection device 14 that is constantly in contact with the rope 5. Is a child.

In addition, the elevator safety device including the door rope slack detection device 14 attached to each floor door operates as shown in the flowchart of FIG. Also, after deleting all the car calls and floor calls that have been registered up to that point, the call for the floor on which the door rope loosening detection device 14 has operated is registered, and when the car touches the floor and opens the door, It stops the elevator operation. According to this embodiment, when the door rope slack detection device 14 operates, the car is immediately guided to the above-mentioned operating floor regardless of which floor the car is located, and the floor is opened and the door is on standby. The safety of the elevator can be improved.

[0010]

[Effect of device]

 According to this invention, since the car is preferentially landed on the floor on which the rope slack detection device operates, it is possible to prevent an accident that someone falls into the hoistway from the door on that floor.
