Description

Technical Field

[0001] The utility model relates to the technical field of elevator installation, in particular to a wire rope unwinding device used for elevator installation. Background Art

[0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped pod. It is used to transport people or goods in multi-story buildings. When lowering the wire rope during elevator installation, the speed of lowering the wire rope cannot be controlled. Lowering the wire rope too slowly will lead to reduced work efficiency, while lowering the wire rope too quickly may easily cause accidents.

[0003] A wire rope unwinding device for elevator installation disclosed in the Chinese utility model patent application publication specification CN213802485U is provided with a monitoring mechanism and a jamming mechanism. When the rope unwinding speed is too fast, the wire rope drives the monitoring wheel to rotate, the monitoring wheel drives the small gear to rotate, the small gear drives the large gear to rotate, the large gear drives the through hole to rotate, and the infrared receiver receives infrared rays from the infrared transmitter through the through hole. The faster the rope unwinding speed is, the higher the receiving frequency is. At this time, the second motor is started by controlling the external solenoid valve, the second motor drives the rotating shaft to rotate, the rotating shaft drives the two threaded sleeves to rotate, the two threaded sleeves drive the two threaded rods to move, and the two threaded rods drive the two splints to move relative to each other until the two splints press the wire rope tightly and jam it, thereby avoiding jamming caused by the wire rope unwinding too fast. However, the wire rope is retracted and released for a long time, and there is a lack of lubrication and maintenance of the wire rope body, which shortens the service life of the wire rope and poses certain safety hazards.
