Construction lifter control system

Abstract

The invention discloses a construction lifter control system, and relates to the field of lifter control systems. According to the construction lifter control system, the control operation mode of a lifter is switched into a manual operation mode or an automatic operation mode through an electric lock switch, and the lifter is controlled to operate to any height of a floor; and logical judgment isconducted through a PLC to obtain whether the lifter is on a flat layer or not, and thus a lifter door and a floor door are controlled to be opened or closed. According to the construction lifter control system, the construction lifter can parked at any height, and meanwhile, collision noise caused by the use of a mechanical lock and a car cam is avoided.

Description

technical field [0001] The invention relates to an elevator control system, in particular to a construction elevator control system. Background technique [0002] In recent years, with the development of the construction industry, construction elevators have played an increasingly important role in the construction industry. As an important equipment in the construction industry, construction elevators are disclosed in the prior art to realize automatic leveling of construction elevators. Floor selection and other functions, but its function is relatively single, the construction elevator can only be parked at the leveling position, and cannot cope with various situations in actual construction; in addition, the existing technology uses conventional mechanical locks, between the elevator door and the floor door There are hooks, pull rods, return springs and swing rods on the doorposts, and the swing rods and hooks respectively touch the upper and lower touch irons in front o...

[0002] In recent years, with the development of the construction industry, construction elevators have played an increasingly important role in the construction industry. As an important equipment in the construction industry, construction elevators are disclosed in the prior art to realize automatic leveling of construction elevators. Floor selection and other functions, but its function is relatively single, the construction elevator can only be parked at the leveling position, and cannot cope with various situations in actual construction; in addition, the existing technology uses conventional mechanical locks, between the elevator door and the floor door There are hooks, pull rods, return springs and swing rods on the doorposts, and the swing rods and hooks respectively touch the upper and lower touch irons in front of the corresponding elevator and the nails on the floor door and counterweight to realize the lift door and floor door. When the elevator is running, the iron will press the swing rod to make the hook break away from the counterweight, and the floor door will fall and close by its own weight; when the elevator stops, the floor door will be unhooked after being pressed by the iron, and the floor door can be opened. During use, the mechanical lock collides with the iron to make a lot of noise
