Description
Technical field
The utility model relates to brake switch detection technique field, is specifically related to a kind of brake switch condition checkout gear.
Background technology
At present; in ironmaking production; the main belt of blast furnace feeding is being undertaken from groove the task to furnace roof convey materials; in large blast furnace, main belt need per hour transport more than 700 tons material; huge and the continuous running of operational throughput; because main belt gradient is large and convey materials weight, be protection equipment and production safety, brake gear is generally installed in driving system.
In brake gear use procedure, often there is the fault that drg pusher causes, the faulty condition that main manifestations is that pusher power lead is disconnected, pusher internal damage and pusher lack hydraulic oil, cause drg normally not open and change closed condition in closed condition or from open mode, affecting equipment operation.Be embodied in following two kinds of situations, 1. motor is in start-up course, should first open drg, restart motor, if drg is not opened and always in closed condition when starter motor, be a kind of faulty condition of drg, and PLC control system does not detect this fault of drg, continue to control electric motor starting; 2. motor is in operational process, drg should be always in open mode, can not close, if drg is closed suddenly in motor operation course, it is exactly a kind of faulty condition of drg, and PLC control system does not detect the fault that drg is closed suddenly, continue to control motor operation, below either way showing as drg closes, also cause identical result, cause the fluid coupling that connects main belt motor and reductor to damage, the serious main belt motor that will cause burns, damage electrical control equipment, cause tremendous economic loss.Visible; in main belt control system; need to detect the opening and closing state of drg; and participate in motor and move chain control; just can realize the protection to main belt fluid coupling and electrical equipment; and there is no now a kind of device that can detect brake switch state, this is the existing weak point of prior art.
Therefore, need a kind of brake switch condition checkout gear, when drg opens and closes, this device can detect brake status to be changed, and switch state signal is transferred to PLC control system, PLC control system and then main belt motor is carried out to chain control, guarantees blast furnace main belt equipment smooth operation.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of brake switch condition checkout gear for the defect of above-mentioned existence.This device is by direct-detection brake level change in location; indirect detection is to the method for brake switch state; there is simple in structure, easy to maintenance, feature accurately and reliably; brake switch state can be detected; and give in time PLC control system and send signal; the operation of control motor, protects main belt fluid coupling and electrical equipment.
A kind of brake switch condition checkout gear technical scheme of the present utility model is, comprise brake level, brake control lever and the pusher being connected with brake level, brake level and brake control lever are hinged, it is support motion that brake level be take with the hinge-point of brake control lever, pusher is positioned under brake level one end, on brake level, be provided with position probing plate, under position probing plate, be provided with travel switch.
Travel switch is connected with PLC control system.
Preferably, travel switch is JLXK1 series.
Travel switch is fixed on travel switch base plate.
Travel switch base plate is fixed on brake control lever.
Adjust the position of position probing plate, while making to lift on brake level, position probing plate can be separated with travel switch, when brake level falls, position probing plate can contact with travel switch, drive the action of travel switch auxiliary point simultaneously, travel switch inside connects one group of normally closed some signal, in signal input PLC control system, signal is connected indication drg and is opened, and signal disconnects indication drg and closes.
Preferably, travel switch base plate is steel plate.
