Abstract

The invention refers to a kind of measuring device for measuring the brake moment of elevator arresting gear, especially measuring device and the method which uses torsion lever and strain piece as sensitive elements, and uses microprocessor to carry on signal calculation, analysis and process. The invention is made up of beam, torsion lever, main shaft, arresting gear and circuit. The arresting gear is connected with the beam through two pin shafts, the braking beam is connected to one end of the torsion lever, and the braking clamp is connected with the iron core, and then connected with the beam. The arresting gear coil is embedded in the iron core, there set strain pieces on the surface of torsion lever, the pieces are connects into a bridge circuit. The advantages of the invention are: it designs the zero calibration, deficiency analyzing of arresting gear and so on. It has a high accuracy, no float, and high reliability.

Description

technical field [0001] The invention relates to a measuring device for the braking torque of an elevator brake, in particular to a braking torque measuring device and a method thereof which use a torsion bar and a strain gauge as sensitive elements, and use a microprocessor for signal calculation, analysis and processing. Background technique [0002] With the development of science and technology and the improvement of mechanical design level, various automatic control devices have been used more and more in various mechanical devices, and various sensing and detection devices supporting automatic control devices have become indispensable. Components, because it plays a decisive role in the accuracy and safety of the control. The braking torque measuring device plays an important role in elevator weighing, overload alarm, starting torque control, etc. The traditional elevator weighing device is installed on the wire rope head or the bottom of the car. Due to the zero drift...
