Elevator steel wire rope wire and strand breaking detection device

Abstract

The invention relates to an elevator steel wire rope wire and strand breaking detection device which comprises supports, round steel, metal wires, a plurality of thin nylon wires, a trigger piece and a micro switch. The round steel is horizontally arranged between the two supports and can rotate around the central axis of the round steel, the metal wires are fixed on the round steel at intervals, the thin nylon wires are connected between the metal wires, so that elevator steel wire ropes are located in a space defined by the metal wires and the thin nylon wires, one end of the trigger piece is fixed on the round steel, and the micro switch is fixed on the supports. The contact of the micro switch is in contact with the other end of the trigger piece, and the output end of the micro switch is connected to a control system of an elevator. When wires and strands of the elevator steel wire ropes are broken, the broken wires or strands can touch the metal wires or the thin nylon wires, the round steel is driven to rotate, the trigger piece is made to be separated from the contact of the micro switch, so that a control system of the elevator is controlled, and the elevator is forced to stop operating.

Description

technical field [0001] The invention relates to a detection device for broken wires and broken strands of elevator steel wire ropes. Background technique [0002] The elevator wire rope is one of the most important safety components of the elevator. Due to the different actual frequency of use of the elevator, the service life of the wire rope is also different. Every year, the relevant national inspection agencies and maintenance departments need to carry out regular or irregular inspections on the working conditions of the elevator wire rope. During the detection, if the broken wires and strands of the steel wire rope are found, they must be replaced in time. However, this kind of regular or irregular detection alone cannot achieve real-time monitoring. When the elevator steel wire rope is broken and broken, then The wire rope will further expand the number of broken wires and strands in a short period of time, causing the wire rope to break or burst, bringing serious safe...

[0002] The elevator wire rope is one of the most important safety components of the elevator. Due to the different actual frequency of use of the elevator, the service life of the wire rope is also different. Every year, the relevant national inspection agencies and maintenance departments need to carry out regular or irregular inspections on the working conditions of the elevator wire rope. During the detection, if the broken wires and strands of the steel wire rope are found, they must be replaced in time. However, this kind of regular or irregular detection alone cannot achieve real-time monitoring. When the elevator wire rope is broken and broken, then The wire rope will further expand the number of broken wires and strands in a short period of time, causing the wire rope to break or burst, bringing serious safety hazards to passengers and equipment

[0003] At present, the detection of broken wires and strands of elevator wire ropes mainly includes hand touch detection, ultrasonic detection, and X-ray detection. The above methods are more effective and have good accuracy, but the work is labor-intensive and inefficient. The steel wire rope fracture detector evolved from the flaw detection equipment can detect the steel wire rope fracture at the early stage, but the installation is cumbersome and the cost is extremely high
