Barrel sensing intelligent brake for elevator

Abstract

According to the barrel sensing intelligent brake for the elevator, a force transmission middle shaft is connected with a barrel through a sensor, and the sensor comprises a middle part connected with the force transmission middle shaft, an outer circumferential part connected with the barrel and a communicating spoke for transmitting elastic force accumulated by a disc spring from the middle part to the outer circumferential part; the side wall of the communicating spoke is provided with a strain gauge for converting deformation into an electric signal; and the sensor is provided with an integrated amplifying circuit which is used for processing the electric signal and is connected with a peripheral electric control system. When the elevator is braked, a direct quantitative and digital intelligent means is provided for judging the braking positive pressure of the elevator, signals can be visually and rapidly detected, digital conversion of analog signals is achieved, workers can rapidly know the braking positive pressure numerical value situation of the intelligent brake of the elevator, and the working efficiency is improved. When safety problems occur, judgment can be made quickly, measures can be taken, and braking safety of the elevator is guaranteed.

Description

technical field [0001] The invention belongs to the field of on-site safe operation, maintenance and monitoring of mine hoist equipment, and in particular relates to a cylinder sensor intelligent gate for a hoist. Background technique [0002] The mining hoist is the key equipment for underground mining and transportation of metal ore and coal. The key to the safe operation of the hoist is that the braking force of the braking system needs to be maintained within the safe limit to ensure the working braking and safety of the whole system during the working process. The reliability of emergency braking, and the key link of the braking system lies in the brakes. The brakes used in the past cannot digitally monitor their braking force. The key to solving this technical problem is to upgrade the brakes to be able to realize It is an intelligent brake that is force monitoring type and realizes remote digital control, real-time monitoring, operation and fault record, maintenance a...
