Abstract

The invention provides an anti-falling monitoring device and an anti-falling monitoring system for an elevator as well as a monitoring method for the anti-falling monitoring system. The monitoring system comprises the elevator falling-preventing monitoring device, a data acquisition card and a computer, wherein the elevator falling-preventing monitoring device selects an incremental magnetic grid sensor; when equipment to be detected falls, a sensing band and a magnetic sensing head of the incremental magnetic grid sensor are driven to simultaneously work; the data acquisition card is used for acquiring data of the sensor in real time and transmitting the data to the computer through a shielded data cable; the computer is used for analyzing the received information and generating a speed-system distance curve which vividly reflects the operation state of a construction elevator. The monitoring system disclosed by the invention overcomes the own defects of detection equipment and test errors caused by human operation factors and has the advantages of high accuracy, wide range and distance testing range and no test limitation; the monitoring device is easy to assembly and disassembly, is also suitable for safety monitoring of equipment with similar structures, such as the elevator, and is wide in application range.

Description

technical field [0001] The invention relates to the field of safety detection of construction elevators, in particular to an elevator anti-drop monitoring device, a monitoring system and a method thereof. Background technique [0002] The construction hoist is a dual-purpose vertical transportation machine for passengers and cargo that can transport materials and personnel in layers. According to the transmission form, it is divided into rack and pinion type, wire rope type and hybrid type. Among them, the SC-type rack and pinion construction elevator is currently the most commonly used elevator for people and goods in domestic construction enterprises. This machine adopts the electric rack and pinion transmission mode for lifting and driving to realize the vertical transportation of the lifting cage. It has a simple structure. , Easy to use, fast lifting, stable transmission, etc., are widely used in high-rise building construction. [0003] The construction hoist is a lar...
