Description
Technical field
The present invention relates to one and can send early warning information before chain belt generation off-axis fault, and detection and the prior-warning device of the exact position damaging chain belt connecting shaft place in the case of not stopping chain tape running, can be determined.
Background technology
For iron-smelter, the safety of molten iron is of paramount importance.When there being residue molten iron to be difficult to pour out at steel-making in hot-metal bottle, or when the subsequent handling such as ironmaking production molten iron surplus out, steel-making cannot consume completely, molten iron is fabricated to bread ferrum by the chain belt machine being necessary for cylinder iron machine.But because chain belt capacity is little, cast iron speed is slow, so causing chain belt stream time long, load is high.Again because being to be connected by axle between chain belt and the chain belt of pig machine, so, the mechanical friction loss of chain belt connecting shaft and spoilage are the highest.If chain belt connecting shaft fracture when turning over ferrum, being likely to result in that the fracture of whole chain belt, molten iron are excessive, even the security incident such as blast occurs, and maintenance duration, workload are huge, delay entirety and turn over ferrum progress, these all will cause huge loss to enterprise.Used the mode that workman patrols and examines in the past, but during because normally turning over ferrum, the part between two chain belt cannot check.And the environmental quality that scene temperature is high, iron powder concentration is high, water vapor concentration is high, visibility is low, and pig machine turns over ferrum and has certain emergentness, when subsequent handlings such as running into steel-making breaks down, pig machine is accomplished by temporary emergency and turns over ferrum.These combined factors are got up, and result in manual inspection and often cannot scent a hidden danger in time, cause chain belt breaking axis to be difficult to avoid that.
Summary of the invention
The purpose of the present invention is aiming at the deficiency existing for prior art, and provide a kind of workman of need not to patrol and examine the chain belt of pig machine device technique scheme being obtained with fault message, the device of the program utilizes the device such as touching extension arm, touching switch, achieve chain belt connecting shaft rupture, deform, the warning of the situation such as come off, it is ensured that equipment, the person, the safety of production.
nullThis programme is achieved by the following technical measures: a kind of chain belt of pig machine off-axis fault detect and prior-warning device，Including cast iron die，The both sides of cast iron die are provided with chain tape，Chain tape is supported by chain belt rolling support axle，Connected by chain belt connecting shaft between chain belt on chain tape，Chain belt connecting shaft corresponding on two chain tapes is connected by connecting rod，The feature of this programme is: chain tape side is provided with prior-warning device，Described prior-warning device includes touching switch，Drive the touching extension arm of touching switch Guan Bi，Touching extension arm is arranged on the side of the chain tape direction of motion，Touching switch is connected with a PLC，PLC is connected with a display screen，Described touching switch is also connected with an alarm，Additionally，A speed encoder is had to be connected with PLC，Speed encoder is connected with chain belt rolling support axle，And rotate coaxially with chain belt rolling support axle.
At chain tape, the side of cast iron die is provided with scale.
Described touching switch, alarm, speed encoder is installed in a casing.
Touching extension arm is brace, and one end of touching extension arm is arranged in casing, and the other end is to the lopsidedness of chain tape.
Being provided with an ACK button, described ACK button and the series connection of the first relay on casing, the normally-closed contact of the first relay is connected with alarm, and described alarm is also connected with the second relay, the normally opened contact of the second relay and touching switch in parallel.
Alarm is audible-visual annunciator.
The two ends of chain belt connecting shaft are provided with the bayonet lock preventing chain belt landing.
Display screen is for touching display screen.
The beneficial effect of this programme can be learnt according to the narration of such scheme, owing to there being touching extension arm in this scenario, when chain belt connecting shaft is damaged by external force deformation or the bayonet lock of axle head comes off or connecting rod ruptures, when causing chain belt connecting shaft to be subjected to displacement, touching extension arm will be encountered, touching body extension arm action, make touching switch Guan Bi, signal is passed to PLC, and alarm sends warning, now, second relay Guan Bi, the normally opened contact Guan Bi of the second relay, thus achieve interlocking, make alarm send chimes of doom always, after only staff presses ACK button, first relay obtains electric, the normally-closed contact of the first relay disconnects, alarm dead electricity, stop alarm；There is speed encoder, velocity amplitude when chain belt connecting shaft breaks down can be measured.Then automatically calculated by PLC, it is possible to obtain the distance that chain belt connecting shaft is run after out of service from the chain belt that breaks down, then by scale, staff just can find the chain belt connecting shaft broken down.The touching extension arm lopsidedness to the chain belt direction of motion, when thus being avoided that chain tape running, touching extension arm snaps in chain belt, damages chain belt or touching extension arm；The alarm of this programme, the first relay and the second relay can pass through mains-supplied or storage battery power supply.As can be seen here, the present invention compared with prior art, has prominent substantive distinguishing features and significantly progress, and its beneficial effect implemented also is apparent from.
