Abstract

The utility model relates to a real time speed measuring controller for a hoist. A pulse signal generator 3 is fixedly connected with the shaft end of tension-side wheels of a hoist, a speed measuring sensor A is installed against the pulse signal generator and is used for receiving pulse signals which are emitted by the pulse signal generator, the sensor A can be electrically connected with a programmable controller B, and the controller B is respectively electrically connected with a setup unit C and AC contactors K1 and K2. The programmable controller B is used for calculating and comparing the signals of the sensor A with set values, the abnormal feeding of the hoist can be automatically adjusted according to the comparison values, the hoist is always in a real time monitoring state, and the normal work efficiency of the hoist is ensured.

Description

The gig control setup that tests the speed in real time

The utility model is a kind of gig control setup that tests the speed in real time, measures and control the rotating speed of gig by velocity measurement mechanisms and circuit of measurement and control, to reach a kind of control setup of guaranteeing the gig normal operation.

Present many gigs can not get timely detection, the rotating speed of gig is difficult to measure, and feed system is wayward, often produces when promoting material that drug on the market, or supply can not meet requirements situation, this has greatly influenced the work efficiency and the service life of gig.

The purpose of this utility model is that a real-time control apparatus is set on gig, it can be measured the rotating speed of gig at any time and calculate with setting value, compares, by the situation of calculating, comparing, instruction stops a last feed process equipment automatically and stops charging work or restart charging work, in case have problem automatic fault to report to the police, and automatic trouble-shooting.This can greatly reduce breakdown rate, can improve the normal operation efficient of gig.

The purpose of this utility model is to realize like this, the gig control setup that tests the speed in real time is made up of velocity measurement mechanisms and circuit of measurement and control, velocity measurement mechanisms is made up of pulse signal generator and tachogenerator A (being called for short sensors A down), and circuit of measurement and control is made up of Programmable Logic Controller B (following abbreviation controller B), setup unit C and AC contactor K1, K2.Pulse signal generator is fixed on the axle head of gig tension wheel and with tension wheel and rotates synchronously, sensors A is fixed on the support of gig by support, the detection sensor head of sensors A is over against the signal generating region of pulse signal generator, sensors A is electrically connected with controller B, controller B is electrically connected by control cable with setup unit C, and controller B and AC contactor K1, K2 are electrically connected.Concrete method of attachment is that sensors A is electrically connected with power supply 24+, the COM of controller B, the signal input part of sensors A is electrically connected with the XO end of controller B, X1, the X2 end of the open contact of AC contactor K1, K2 and controller B is electrically connected, the coil of AC contactor K1, K2 and loudspeaker P respectively with Y0, Y1, the Y2 electrical connection of controller B.

Controller B selects FXON-24MR for use, and setup unit C selects FX-10DU for use, and sensors A is selected HONEYWELL9922 series for use, and AC contactor K1, K2 select CJZ1 series for use, and loudspeaker P selects the FMZJ type for use.

Principle of work of the present utility model is: the rotating speed of gig, operating condition is sent by the pulse signal generator that is fixed on the tension wheel, and be input among the controller B after being recorded by the detection sensor switch of sensors A, controller B gathers the signal that transmits from sensors A in real time and calculates with the setting value of having imported, relatively, carrying out different output according to comparative result handles, when impulse singla during less than setting value, controller B stops the charging of a last operation automatically, and send alerting signal, when impulse singla value during greater than setting value, controller B can start the charging of a last operation automatically, and stops to report to the police.Gig is in real-time monitor state always like this, can adjust the feed situation of gig at any time, makes it be in optimum Working, has reduced the accident rate of equipment, has guaranteed the normal operation efficient of gig.

Owing to adopt technique scheme, make gig be in real-time monitor state always, can adjust the feed situation of gig at any time, and the mal feed is handled at any time automatically, so just greatly reduce breakdown rate, guaranteed the normal operation efficient of gig.

Below in conjunction with drawings and Examples the utility model is further described.
