Abstract
The utility model relates to a tension monitoring changeover device for hoisting ropes. In the tension monitoring changeover device for hoisting ropes, two drawplates which are in the parallel status and are connected with a hoisting container are fixedly connected by a pin shaft and an upper pressure plate. The acting force of the tension monitoring changeover device for hoisting ropes is downward, which can make two connecting plates connected with the hoisting rope and two drawplates in the vertical position. Lower pressure plates are vertically fixed between the lower parts of the two connecting plates, the upper pressure plate and the pin shaft. A force and electricity converter is arranged on each lower pressure plate. The acting force of each connecting plate is upward. When the force and electricity converter is pressed, a pressure sensor can output signals which can be received by a telemetering radio transmitter and the data is processed by a microcomputer. Thus the online monitoring and the continuous metering of the pulling force of the hoisting rope can be realized.
Description
The utility model relates to a kind of mine hoisting machinery device, especially a kind of single rope or multi rope winding steel wire rope tension monitoring transfer device.
In mine is produced, the problem that multi-rope friction hoist system need solve is each steel rope discontinuity equalization problem, and all there is not device for measuring force on the suspension gear that the colliery is used, generally be with Bo Fa and the labelling method etc. of shaking, as the ripple method of shaking is that lifting container is parked in the shaft bottom, vertically hit steel rope and the ripple that produces is propagated along steel rope with impulsive force, can calculate the suffered tension force of steel rope with formula by the wave propagation cycle, generally can only estimate the equilibrium situation of each rope tension qualitatively.It is at present domestic that also to have preferably be " strain gauge " with strain principle mensuration steel wire rope tension, when measuring, make sensor stressed, data are handled by instrument, relatively more directly perceived, better than preceding kind of method, but yet have some problems, the tester is in cage when using at the scene, inconvenient operation can not be monitored at random.If when using skip hoisting, tension detection equipment, instrument and personnel all on the skip bucket platform, its work under bad environment, also very dangerous.And said method all will stop when measuring tension force, and influence is produced, thereby mensuration that can only be regular once, and is inaccurate, more at random on-line monitoring.
The purpose of this utility model is to develop a kind of telemetering system of new steel wire rope tension in order to overcome above-mentioned the deficiencies in the prior art part, it mainly is the pulling force between lifting container and the hoisting cable to be connected change the pressure connection into, after making the pressure sensor pressurized, the pressure sensor output signal, through remote measurement wireless transmission and reception, the data MICROCOMPUTER PROCESSING, then practicable on-line monitoring.
Task of the present utility model realizes that as follows it mainly is made up of arm-tie, bearing pin, lower platen, top board, connecting plate, catch, baffle plate, bolt, power-electric transducer, briquetting, force bearing plate and socket bolt.To be in two arm-tie captive joints that be arranged in parallel by bearing pin and top board, the arm-tie bottom is connected with lifting container by bearing pin; Make two connecting plates and two arm-ties be in upright position each other, between the bottom of two connecting plates, top board and bearing pin, become vertical direction to be fixed with lower platen, make arm-tie become to flexibly connect with connecting plate, be fixed with a power-electric transducer on the lower platen, there is force bearing plate power-electric transducer both sides, upper top has briquetting, on four angles of top board a socket head cap screw is arranged respectively, and passes top board and contact with the upper surface of force bearing plate; When lifting container and load act on two arm-ties and the top board by bearing pin, application force is downward, and hoisting cable is connected with connecting plate and lower platen through connecting device, its application force upwards, in being mounted in middle pressure driver (power-electric transducer) pressurized of upper and lower pressing plate, the output signal of pressure sensor is directly proportional with the terminal loading-lineoutofservice signal pull of hoisting cable, this signal output is after remote measurement wireless transmission and reception, and the data MICROCOMPUTER PROCESSING can realize the pulling force of hoisting cable is carried out on-line monitoring and continuous measurement.
The utility model has the following advantages compared with prior art:
The utility model is by the pressure sensor output signal to the measurement of hoisting cable tension force, through wireless telemetering and MICROCOMPUTER PROCESSING, can realize on-line monitoring, need not stop during dynamometry, do not influence production, and multiple functional, highly sensitive, safe and reliable, simple in structure, make easily, be convenient to install.
