Description

  The present invention relates to a moving cable device for an elevator having a moving cable for connecting a control panel and a car.

  A conventional elevator moving cable is a power line or communication line for lighting in a car. One end is suspended at the bottom of the car and the other is connected to the control panel of the machine room. At the same time, the U-shaped bending motion is repeated. Conventional moving cables for elevators have been manufactured as round rubber cables by embedding a core group formed by twisting a plurality of insulated cores in a sheath. Therefore, it is sufficient to prepare as many moving cables as the number of power lines and signal lines necessary for the mounted elevator, and the production cost of the elevator can be reduced. However, when the number of moving cables for elevators increases, the cables collide with each other or the cables collide with the hoistway wall or the car when the car moves up and down, and the cables are damaged, and noise is generated. There was a problem to do.

  In view of such a situation, a conventional elevator moving cable having a flat cross-sectional belt-shaped body manufactured by covering a plurality of wire cores arranged uniformly in the width direction with a sheath has been proposed. (For example, refer to Patent Document 1). In the conventional elevator moving cable according to Patent Document 1, since a plurality of wire core groups are arranged in the width direction in one moving cable, there is no collision between the cables when the car moves up and down. Further, the collision between the cable and the hoistway wall and the car is suppressed, and the occurrence of cable damage and noise are suppressed.

  However, in the conventional moving cable for elevators described in Patent Document 1, since a necessary power line and signal line are different for each mounted elevator, it is necessary to produce a dedicated moving cable each time, There was a problem that the cost increased.

  The present invention has been made to solve the above-described problems. For each elevator, a necessary number of cable units are connected and integrated to form a moving cable, thereby reducing the production cost of the elevator. Elevator moving cable device that prevents the cable unit from colliding with each other, prevents the cable unit from colliding with the hoistway wall and the car, and prevents damage to the cable unit and noise. The purpose is to obtain.

  The elevator moving cable device according to the present invention includes a moving cable having one end suspended from a lower portion of a car and the other end connected to a control panel. The moving cable includes a plurality of cable units, The cable units are connected in a line in the width direction, and are configured as a strip having a flat cross-sectional shape.

  The moving cable is configured by a plurality of cable units arranged in a line in the width direction and connected to each other to form a flat cross-sectional strip. Therefore, since the number of moving cables is one, there is no collision between the cable units, the occurrence of collision between the cable unit and the hoistway wall and the car is suppressed, and the occurrence of insulation coating damage and noise Generation can be suppressed. Furthermore, if you prepare multiple types of cable units, you can select the type of cable unit required for the elevator and configure the desired moving cable, so there is no need to manufacture a moving cable that meets the requirements for each elevator, Production costs can be reduced.
