Abstract

<P>PROBLEM TO BE SOLVED: To enable a person riding on a simple lift without guide rail to drive the lift by himself/herself solving the problem that the person can not drive the lift by changing the lift into structure incorporated with an operation cable inside a rope or wire for suspension. <P>SOLUTION: In the lift for suspending a riding suspension stage or a riding basket 1 with a rope or wire 4 and winding up/unwinding this rope or wire with a wind-up drum 3, an operating cable 5 is built in or rolled in the rope or wire 4 and integrated so that both the rope or wire and the cable can be simultaneously wound up and unwound around the wind-up drum 3. Thus, in such a lift, the person riding on the riding suspension stage or riding basket 1 can operate a motor 10 for wind-up via the operating cable 5 by an operating switch 12 or the like, can stop the motor 10 for wind-up by transmitting the operation of an upper limit switch 13 or lower limit switch 14 to the operating cable 5 or can transmit a call in the case of emergency via the operating cable 5 to the outside as well. <P>COPYRIGHT: (C)2003,JPO

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylinder-type lifting device, which is particularly effective for emergency evacuation. 2. Description of the Related Art A simple elevating device without a guide rail cannot be operated by a person riding on it, and thus cannot be used even in an emergency. [0003] The occupant can drive down on his / her own and can stop automatically at the lower limit, thereby making it possible to safely evacuate in an emergency.
After the descent, the next person can be evacuated again by returning to the upper limit position. A riding stand or a riding basket 1 is suspended by a rope or a wire 4 or the like, and this is suspended by a hoisting drum 3.
In an elevating device that winds up and rewinds, the operating wire 5 is built in or wrapped around the rope or wire 4 or the like, so that both can be wound around the hoisting drum 3 at the same time and can be rewound. A passenger on the hanging stand or the riding basket 1 operates the hoisting motor 10 through the operation power supply 5 by the operation switch 12 or the like, and also informs the operation power supply 5 of the functions of the upper limit switch 13 and the lower limit switch 14. The hoisting motor 10 is stopped, or an emergency signal can be transmitted to the outside through the operating wire 5. The riding suspension or the riding basket 1 is moved from a very high place to the ground. In the case of lowering, the operating wire 5 is naturally very long, and when this is wound up separately from the rope or the wire 4, when the wire is unwound, a difference in winding margin occurs between the two and the smooth winding. Raising is impossible. Therefore, by integrating the operation electric wire 5 with the rope or the wire 4, this defect is corrected,
It can be wound up on the hoisting drum 3 in a regular manner without any loosening. As shown in FIGS. 1 and 2, the operation wire 5 coming out of the operation circuit box 8 passes through the brush shoe 7 and the contact ring 6, passes through the operation wire 5 built in the rope or the wire 4, and is used for riding. It is connected to the operation switch 12 of the stand or the riding basket 1. The passenger of the riding stand or the riding basket 1 can use this switch 12 to freely operate the hoisting motor 10 through the operating electric wire 5. Therefore, it is possible to land on the ground more safely from a high place. As shown in FIG. 1 and FIG. 2, a riding stand or a riding basket 1 is connected to a rope or a wire 4 by a rope fixing bracket 2, and the rope or the wire 4 is wound. It is wound around the upper drum 3, and is wound up and rewound by a hoisting motor 10. The operation electric wire 5 which has exited the operation circuit box 8 is connected to the operation electric wire 5 built in or wound around the rope or the wire 4 through the brush shoe 7 and the contact ring 6, and the operation set on the riding stand or the basket 1 for riding. Switch box 12 has been reached. Therefore, when the passenger operates this switch, the operation circuit 8 is operated, whereby the hoisting motor 10 can be operated. Upper limit switch 13 and lower limit switch 14
Is branched from the operation switch box 12, and by this operation, the operation circuit can be operated and the hoisting motor 10 can be stopped. An emergency signal can also be transmitted to the outside through the operation wire 5. [0007] Until now, there was no other way to evacuate with equipment simpler than a high place, other than a rope ladder. The present invention seeks to meet this need with relatively simple equipment.
