Abstract
The utility model pertains to a steel wire rope tension measuring and controlling unit of multi rope friction hoisting machine, which pertains to mine automation field. Two groups of totally 4 to 6 load transducers are connected with a microcomputer data collection unit that is connected with a wireless transmitting unit. The wireless transmitting unit is communicated with an upper system transmitting unit or an under ground tranceive unit that is connected with the microcomputer which is connected with the upper system transmitting unit. The upper system transmitting unit is connected with the upper system processing unit which is connected with a monitor, an alarm and a signal control machine respectively. The utility model has the advantages of novel structure and solves the problem of difficult to measure the tension of the cable wire of hoisting machine due to the difficulty of wireless communication.
Description
Technical field
The utility model belongs to the mine automatic field, especially a kind of system that multirope friction winder tension force is carried out observing and controlling.
Background technology
Multirope friction winder is one of visual plant of mine production, and great serious accidents such as gig pulleying during domestic in recent years mine produces, bob well happen occasionally, and cause heavy losses and personal casualty.The major cause that causes the multirope friction winder interruption of service has following two: the one, and tension force distributes uneven between many ropes, Tension Difference must not surpass 10% between each steel rope of " safety regulations in coal mine " regulation multirope friction winder, uses traditional notation, spring balance method, the tension force relations of distribution between each steel rope of the ripple method of shaking guestimate in the actual production at present mostly.These method errors are bigger, can't solve the problem of the long-term overload operation of single rope, thereby have steel rope and liner wearing and tearing aggravation thereof, so that the accident potential of disconnected rope; The 2nd, the gig overload operation, at present domestic to the fixed heavy technology comparative maturity before the elevator-cup loading, secondary loads and unloading does not wait the overload problem only but can't solve, thereby exists gig pulleying, card jar until the accident potential of weighing down well.
Summary of the invention
The utility model provides a kind of multirope friction winder steel rope tension observe and control system, to solve the long-term overload operation of single rope, the steel rope that exists and liner wearing and tearing aggravation thereof so that the problem of disconnected rope.The technical scheme that the utility model is taked is: 4～6 load transducers one are connected with microcomputer data acquisition unit one, and this microcomputer data acquisition unit one is connected with wireless transmit/receive units one; 4～6 load transducers two are connected with microcomputer data acquisition unit two, and this microcomputer data acquisition unit two is connected with wireless transmit/receive units two; This wireless transmit/receive units one is connected with upper computer Transmit-Receive Unit or the communication of downhole wireless Transmit-Receive Unit, wireless transmit/receive units two is connected with downhole wireless Transmit-Receive Unit or the communication of upper computer Transmit-Receive Unit, this downhole wireless Transmit-Receive Unit is connected with microcomputer, this microcomputer is connected with this upper computer Transmit-Receive Unit, this upper computer Transmit-Receive Unit is connected with the upper computer processing unit, and this upper computer processing unit connects telltale, annunciator and signal controller respectively.
Principle of work is: load transducer is fixed on the slip cushion block of gig steel rope hydraulic pressure adjusting rope device, can directly reflect the actual tension of steel rope, or takes out pressure signal by the hydraulic coupling in the hydraulic pressure hydraulic cylinder for adjusting rope.Sensor output signal carries out data acquisition and processing (DAP) by Single-chip Controlling, send to the wireless transmitter of fixed position then through radio receiving transmitting module, native system is provided with wireless transmitter respectively in shaft station and ground-surface appropriate location, distinguished by different coding between the transmit receive unit, the wireless transmitter that is positioned at the shaft station is sent to ground upper computer receiving element with sensor information through wire communication mode, thereby can solve the problem of pit shaft wireless telecommunications difficulty, the ground upper computer elevator-cup that received well is following and the ground transmit receive unit transmits simultaneously or the load information of cage two side sensers, upper computer is in transmitting-receiving, sensor information is carried out comprehensive analyses and judgement, show then and the abnormal condition warning, when occurring exporting control signal when steel wire rope tension distributes inequality and one-sided tension force summation to surpass allowed band, stop gig and continue operation, thereby prevent the generation of serious accident, in addition, upper computer can be stored the sensor information of longer a period of time, can check each steel rope stressing conditions and change curve thereof sometime at any time, so that steel rope and liner running condition thereof are carried out comprehensive analyses.
The utility model advantage is: novel structure, and load transducer is fixed on gig steel rope hydraulic pressure transfers on the slip cushion block of rope system, guaranteed the authenticity of sensor signal and the stability and the reliability of work thereof.The tension force of skip bucket or each steel rope of cage both sides is measured simultaneously, undertaken showing, reporting to the police and control behind the comprehensive analyses by upper computer, can stop the generation of serious accident, can carry out comprehensive analyses to the running state of steel rope and liner thereof again, transfer rope and turning friction lining to instruct, thereby make gig operate in optimum regime, prolong the service life of steel rope and liner thereof.According to the actual conditions of mine vertical shaft pit shaft, the mode that adopts wireless and wire communication to combine has solved effectively for a long time because wireless telecommunications are difficult and has made the difficult problem that the gig steel wire rope tension can't accurately be measured.
