Abstract
The utility model discloses a stroke detection and control system of lifting machine among mine construction, including PLC controller, converter and infrared distance measuring sensor, infrared distance measuring sensor is used for measuring the real -time degree of depth of newly -built mine, the PLC controller is used for gathering infrared distance measuring sensor's data, changes in the lifting machine functioning speed picture each stage length and respectively changes speed the size of stage acceleration according to of survey data to to converter output control signal, the converter is used for the operation according to the control signal control lifting machine motor of PLC controller, realizes becoming stroke control. The simple structure of this system, control performance are good, not only can satisfy among the mine construction change stroke control that realizes the lifting machine operation along with the change of the mine degree of depth, adopt variable frequency speed governing(VFSG) to reach energy -conserving effect moreover.
Description
Technical field
The utility model relates to a kind of mine hoist, specifically a kind of change by detecting mine construction chats well depth and realize the change travel control system of gig.
Background technology
Gig is as down-hole and aboveground direct communication bridge, and the importance of its Stroke Control is self-evident, and especially when mine construction, the continuous change of the mine degree of depth can cause certain influence to the Stroke Control of gig.Therefore, utilize infrared distance sensor and PLC to carry out real-time Detection & Controling to the stroke of gig and seem of crucial importance.
Summary of the invention
The purpose of this utility model devises a kind of by detecting the system that the mine degree of depth changes gig Stroke Control in real time to solve existing issue, comprises PLC, frequency converter and infrared distance sensor, wherein.
Described infrared distance sensor, for measuring the real-time deep of New Built Mine.
Described PLC, for gathering the data of infrared distance sensor, change the time length in each stage and the size of each gear shift stage acceleration/accel in gig running velocity figure according to surveyed data, and export forward and backward on off control signal, speed controling signal and speed-slackening signal to frequency converter.
Described frequency converter, for controlling the forward and backward start and stop of gig motor, velocity variations and braking according to the control signal of PLC, realizes becoming Stroke Control.
Its principle of work is as follows: before mine hoist runs, the real-time deep of New Built Mine is measured by infrared distance sensor, the analog signals that the data collecting module collected infrared distance sensor established in PLC exports the on-off model be converted to needed for PLC, PLC changes the time span in each stage and the size of each gear shift stage acceleration/accel in gig running velocity figure according to surveyed data, and just exporting to frequency converter, reversion on off control signal, speed controling signal and speed-slackening signal, frequency converter controls the operation of winder motor in real time according to control signal, realize becoming Stroke Control.
In mine construction of the present utility model, the stroke detection of gig and control system adopt infrared distance sensor to measure the mine degree of depth in real time, and are adjusted in real time gig Stroke Control by PLC; This system adopts frequency control to the control of gig motor, both ensure that the accuracy of control, and has reached again energy-conservation effect.
