When a fault of displacement of the cable supporter occurs, the total resistance of the sensing circuit changes, and the detecting host detects the total resistance of the sensing circuit and can analyze the fault and the position thereof according to the change of the resistance, and give alarm signals and control information. The utility model has the advantages of simple structure, high reliability and strong anti-interference ability, and can position faults.
Description
The utility model relates to a kind of relative position displacement detecting technology, the device of the rope device displacement fault detect that particularly a kind of cable conveyer or cable crane prop up.
When cable conveyer or crane generation guy device displacement fault, owing to face field environment and work high above the ground, can't determine guy device fault and warning, as adopting related detecting method formality complexity, loaded down with trivial detailsly also being difficult to finish detection.To not seeing correlation technique and the application achievements report that cable conveyer or crane guy device displacement fault detect are arranged so far.
The purpose of this utility model provide a kind of simple in structure, reliability is high, antijamming capability is strong, can the fast detecting fault and fault location cable conveyer or crane guy device displacement failure detector.
The purpose of this utility model is achieved in that a kind of cable conveyer or crane guy device displacement failure detector, it comprises the detection main frame 9 that receives fault-signal and provide corresponding alerting signal and control signal, several and the sensing circuit that fixing short circuit device 5 polyphones of the fixing resistor 4 of main cable 1 and in parallel with each resistor and guy device 2 are formed, sensing circuit is connected with detection main frame 9 by signal wire A, B.The resistor 4 usefulness ply-yarn drills 3 of signal wire A, B and series connection are fixed on main cable 1 time, and the short circuit device 5 in parallel with resistor 4 is fixed on the guy device 2.
The utility model is owing to adopt resistor and short circuit device in parallel polyphone formation fault detect sensing circuit, testing circuit is simple in structure, be suitable for along a plurality of guy device displacement fault detects of high-altitude main cable distribution, and can determine abort situation, can satisfy guy device displacement fault detect requirement fully; After fault takes place, the short circuit device disconnects, the resistance value Rab of sensing circuit changes, this variation belongs to static change, can keep, good stability, antijamming capability are strong, can find this fault fast when the displacement fault appears in certain guy device, and can accurately point out it is which guy device breaks down, thereby improve the equipment safety operation performance.This is meaningful especially for the cable machine of working under the field environment.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the simplified electrical circuit diagram of Fig. 1.
Among the figure: 1, cable machine main cable, 2, guy device (several, be numbered T1-Tn), each guy device is fixed on the main cable by mounting board, 3, wire clamp, be used for signal wire A, B and be serially connected with interior resistor being fixed under the main cable, 4, resistor, each guy device is close to one (being numbered R1-Rn), and its resistance value has nothing in common with each other, and each resistor polyphone inserts among the lead B, 5, short circuit device, each resistance is close to one (being numbered S1-Sn), is made of plain conductor, also can add the flexible connection head therebetween.Each short circuit device Sx two ends also is connected in corresponding resistor R x two ends, resistor is constituted short circuit connect.The short circuit device is fixed on the guy device.When taking place relative displacement above certain numerical value between guy device and the main cable, disjunction of short circuit device or flexible connection head are thrown off, and short circuit was lost efficacy.6, set bolt is used for the short circuit device is fixed on the guy device.7, signal wire B, plain conductor, serial therebetween inserts several resistors and short circuit device.8, signal wire A, plain conductor (also can replace) by main cable.A, B line connect and compose sensing circuit at tail end.9, detect main frame, the displacement fault has taken place, provide corresponding alerting signal and control information after breaking down thereby which guy device the variation of monitoring A, B two resistance R ab analyzes.
Among Fig. 2: R0 is A, B signal wire equivalent resistance; R1-Rn is a n resistor, and they have nothing in common with each other, and for example selects R1=R0, R2=2 R0 ... Rn=nR0; S1-Sn is that n resistance short circuit device Rab is for detecting the sensing circuit all-in resistance.
1, when normal condition, each resistor is detected the sensing circuit all-in resistance by the short circuit of short circuit device
Rab=R0 (1)
2, when X guy device is subjected to displacement fault, the short circuit device Sx that fixes on it will be disconnected, and corresponding resistor R x adds series connection and detects sensing circuit
Rab=R0+Rx=(1+X)R0 X=1,2,…n (2)
3, can get X=Rab/R0-1 (3) by (1), (2) formula
When X=0 represents guy device non-fault
When representing X guy device, X=1-n is subjected to displacement fault
Therefore, by detecting all-in resistance Rab, can judge that according to formula (3) the guy device has the non-displacement fault, and be which guy device breaks down.
Claims (2)
1, a kind of cable conveyer or crane guy device displacement failure detector, it comprises the detection main frame (9) that receives fault-signal and provide corresponding alerting signal and control signal, it is characterized in that: it also comprises the sensing circuit that resistor (4) that several and main cable (1) are fixing and fixing short circuit device (5) polyphone of in parallel with each resistor and guy device (2) are formed, and sensing circuit is connected with detection main frame (9) by signal wire A, B.
