TH36014A - Cable-operated elevator with cable stabilization system - Google Patents

Abstract

To minimize vibrations as much as possible, even when the tether (13) and spring (15) vibrate, [device] is equipped with a properly installed elevator cabinet (1). can Moving up and down in the elevator compartment, the pulley (14) has been installed into the upper part of the This elevator compartment, a cable (13) suspended onto this pulley (14) for the purpose of Pulling the elevator cabinet mentioned above, the suspension rod (9) where the end of this tether (13) will be fixed, the spring (15) is installed down between the bars. This hanger (9) and the elevator cabinet (1) mentioned above. For the purpose of dampening the oscillation, a cylinder device (16) which attenuates the oscillations mentioned above. And has a flow control valve (22), a rotary encoder (24) for locating the elevator cabinet (1) for calculating the length of the cable, load sensing device (25) for sensing. Load of elevator cabinet (1) and control panel (23) calculating the frequency of vibration characteristic f of the cable (13) mentioned above from the length of the cable described above, Calculate the oscillation frequency characteristic of the spring fN from the load of the elevator cabinet (1), and then calculate the ratio. Oscillation frequency u (u = f / fN) and flow volume control valve (22) of the cylinder device (10) mentioned above were obtained when u = 1.

Claims (2)

1. The chain-type elevator system has a unique characteristic that the system consists of a receiving elevator cabinet. Installed so that the elevator can move up and down freely in the elevator compartment, the pulley that has been Installed down to the top of the elevator compartment, a pull-down cable for the elevator cabinet that has been suspended from A pulley, with a pulley fixed to the support beam. Hanging rods that are fixed to the support beam. Vibration dampening springs are installed down between the suspension rod and the lift cabinet, the vibration dampening cylinder device. And there is a valve to control the volume flow, by the loud cylinder device It is installed down between the hanging rod and the elevator cabinet. Location sensor for inspection Location of the elevator cabinet And a control panel for calculating the frequency of vibration characteristic f of the chain from the length of the chain. The oscillation frequency characteristic of the spring fN properties from the elevator hoist and the oscillation frequency ratio of the next u (u = f / fN). The volume of flow of the closed cylinder device is narrowed when u = 1. 2. The cable-operated elevator system is characterized by the fact that the system consists of an elevator cabinet installed. In such a way that the elevator can move up and down the elevator compartment freely. A pulley that has been installed Go down to the top of the elevator lane. The towing cable suspended from the pulley with the pulley is attached to the support beam. Suspension rods are attached to the spring support beam for vibration dampening installed down between the suspension rod and the lift cabinet. It eliminates vibration and has a valve to control the volume flow. The cylinder device is installed down. Go between the hanging rod and the elevator cabinet Position detector for locating the elevator cabinet and control panel for calculating the frequency of the f-characteristic vibration of the chain from the length of the chain, the frequency of the spring fN characteristic vibration from the load of The elevator cabinet and the oscillation frequency ratio of the next u (u = f / fN) by the panel will allow the flaps to control the volume flow of the equipment. The cylinder mentioned above closes narrow as u = 1.
