Rack type vertical elevator operation checking-controlling and positioning system

Abstract

The invention relates to a rack type vertical elevator operation checking-controlling and positioning system comprising a detection unit, a processing unit, a control unit and an executing unit. The detection unit is formed by a tooth-number sensor and a relative detection circuit; the tooth-number sensor can detect changes of tooth numbers; the changes are shaped into a square wave signal by the detection circuit to be sent to the processing unit; the square wave signal can be encoded via non-full state Gary code by the processing unit and calculated to acquire elevator operating speed, accelerating speed and position; and the control unit can output relative frequency and driving force to the executing unit according to an order of the processing unit. By the use of the rack type vertical elevator operation checking-controlling and positioning system, the elevator can work at an enclosed loop control state, so deficiencies of time and labor consumption, inaccuracy of the plane layer due to manual ocular estimation of a traditional rack type elevator, and instability of system open-loop control can be solved; and elevator operation process can be simplified, labor intensity of operators can be reduced and work efficiency can be improved.

Description

field of invention [0001] The invention relates to the field of vertical lifts in the construction industry, in particular to a rack-type building lift, a dual-purpose building elevator for people and goods, and other vertical lifting mechanical devices driven by gears or racks. Operation inspection and control and positioning systems. Background of the invention [0002] The most commonly used rack type vertical elevator in construction machinery is a common transportation equipment for transporting people and construction equipment to the required floor. The derrick of this kind of elevator is fixed on the foundation vertically, and is fixed by the bracket and the building wall. The cage box loaded with people and goods is driven by the motor fixed on the box body to drive the gear along the rack on the fixed derrick to realize the lifting work. . When the box body lifts to the predetermined floor position and stops, this process is called leveling. [0003] In the curr...

This makes the installation even more troublesome

In addition, the working environment of the elevator is very harsh. It is basically exposed to the outdoor environment, and debris such as sand and stones will fall at any time. damage, rendering the system inoperable
