Below in conjunction with accompanying drawing, describe according to steel wire rope tension control monitor unit and the mine hoisting system for mine hoisting system of the utility model embodiment.
Fig. 1 is according to the constructional drawing of the steel wire rope tension control monitor unit for mine hoisting system of an embodiment of the utility model.As shown in Figure 1, the steel wire rope tension control monitor unit 100 for mine hoisting system according to an embodiment of the utility model, comprising: a plurality of tension detectors 110, data link 120, prompting device 130 and controller 140.
Wherein, a plurality of tension detectors 110 detect respectively the tension force of many steel ropes of mine hoisting container (not shown).Data link 120 is connected with a plurality of tension detectors 110 and receives tension force and the ID of the many steel ropes that a plurality of tension detectors 110 detect.Controller 140 be connected with data link 120 with prompting device respectively and according to the tension force of steel rope (also tension force and, mean tension etc.), one of tension force deviation, tension force deviation ratio, tension force deviation accumulated value, tension force deviation variation rate control prompting device 130 alarms with the comparative result of reference value.
The mine hoisting container of mine hoisting system such as skip bucket, cage, mine car and well-bucket etc.While utilizing mine hoisting container to transport personnel or ore etc., conventionally adopt the mode of rope traction mine hoisting container to realize, for increasing, promote load carrying ability, conventionally each mine hoisting container is adopted the mode of many rope tractions, thereby increase the hoisting capacity of mine hoisting system.
The steel wire rope tension control monitor unit 100 for mine hoisting system of the utility model embodiment, whether it makes used time detection steel wire rope tension normal, thereby avoids the generation of danger or accident.For example, a tension detector 110 is all set on every steel-cable suspensioning device, this tension detector 110 can be arranged on the end of the hydraulic push rod of hydraulic lift hitch, also can a mode by paster be arranged on the wooden partition of suspension gear, certainly, also can adopt other modes to be arranged on suspension gear.Thereby can detect the tension force of every steel rope.In an embodiment of the present utility model, tension detector 110 is for example force-sensing sensor.
In above-mentioned example, can to each steel rope, be numbered in advance, for example, in advance for each steel rope distributes an ID, its effect is to distinguish different steel ropes.Like this, according to ID, just can distinguish the tension force of different steel ropes.At tension detector 110, detect after the tension force of steel rope, by data link 120 by the tension force of each steel rope and ID(or not containing ID but by predetermined each steel rope, sequentially send tension force) send to controller 140, so that controller 140 according to the tension force deviation of steel rope, tension force deviation ratio, tension force deviation accumulated value, tension force deviation variation rate or according to steel wire rope tension size (also tension force and, mean tension etc.) control prompting device 130 alarms with the comparative result of reference value.In this example, reference value is determined by empirical value.
For instance, for example there are 4 (4) steel ropes, ID is respectively 01, 02, 03 and 04, for detecting respectively the tension force of 4 tension detectors, 110 detections of 01-04 steel rope, be respectively 100F, 105F, 103F and 140F, the maximum difference 40F between the tension force of 4 of 01-04 steel ropes, and judge based on experience value when the maximum difference between the tension force of steel rope surpasses 30F, just illustrate that the tension force that certain or certain several steel ropes bear is larger, and the tension force that one or several steel ropes of existence bear is less, like this, easily cause and bear tension force and break and have an accident compared with large steel rope.Therefore, controller 140 is interior can be compared the maximum difference between the tension force of steel rope and a preset value (being reference value), as implied above, preset value is 30F, and maximum difference between the tension force of steel rope is 40F, controller 140 judgement steel ropes exist abnormal, there is the tension imbalance between overload and steel rope in steel ropes as several in certain, this time, controller 140 is controlled prompting device 130 and is reported to the police, thereby the accident of avoiding or dangerous generation, the safety while effectively having promoted mine hoisting container operation.
In addition, controller 140 also can be controlled prompting device 130 alarms according to the tension force of every steel rope etc. and the comparative result of reference value.For instance, the tension force that 4 tension detectors 110 corresponding to 4 steel ropes of 01-04 detect is respectively 100F, 105F, 103F and 140F, and reference value is 100F, can think that tension force that tension detector 110 corresponding to 3 steel ropes of 01-03 detect is all in normal range, and the tension force that tension detector 110 corresponding to 04 steel rope detects is not in the reasonable scope, therefore, judgement steel rope exists abnormal, just controls prompting device 130 and reports to the police.In an embodiment of the present utility model, prompting device is such as being but being not limited to: sound and/or visual alarm.
Fig. 2 is according to the constructional drawing of the steel wire rope tension control monitor unit for mine hoisting system of another embodiment of the utility model.
Shown in Fig. 1 and Fig. 2, data link 120 comprises: resultant signal transceiver 121 and branch signal transceiver 122.Wherein, resultant signal transceiver 121 is connected with controller 140.Branch signal transceiver 122 is connected with each tension detector 110 with resultant signal transceiver 121.Further, between branch signal transceiver 122 and resultant signal transceiver 121, radio communication is connected.Like this, facilitate the communication between branch signal transceiver 122 and resultant signal transceiver 121, save the loaded down with trivial details and cost of wiring, and resultant signal transceiver 121 is arranged on ground above (as outer in pithead) conventionally, branch signal transceiver 122 is arranged on the top of the mine hoisting container of motion conventionally, therefore, adopt the mode of radio communication to there is simple possible.Wherein, the mode of radio communication can adopt ZigBee, WIFI, and the Radio Transmission Technologys such as Modbus or agreement realize.
In conjunction with Fig. 1 and Fig. 2, wired connection between branch signal transceiver 122 and each tension detector 110, can be arranged on branch signal transceiver 122 near each tension detector 110 again.Further, between branch signal transceiver 122 and each tension detector 110, be connected with micro controller system 150 or micro controller system 150 is included in branch signal transceiver 122.Micro controller system 150 can gather and process detecting tension force from each tension detector 110, then by branch signal transceiver 122 and resultant signal transceiver 121, is sent to controller 140 in the lump.The tension force that for example micro controller system 150 can detect each tension detector 110 is packed or compresses processing, then the form with data packet is sent in controller 140, also can be read the tension force of each tension detector 110 detection and be sent to branch signal transceiver 122 according to the order of setting and time gap, and then have again branch signal transceiver 122 to be sent to resultant signal transceiver 121, and be sent to controller 140 by resultant signal transceiver 121.Certainly, in other example of the present utility model, micro controller system 150 also available DSP substitutes, and DSP also can be integrated in branch signal transceiver 122.
In an embodiment of the present utility model, controller 140 comprises for storing the memory device (not shown) of the tension force of many steel ropes.To check above-mentioned journal file from memory device in the future, be convenient to analyze according to daily record in the past, thereby provide reference frame for the safety of mine hoisting container being transported later.
