Technical field
The utility model belongs to the mining equipment technical field, is specifically related to a kind of winch cable tractive force pressure sensitive monitoring device.
Background technology
Mine winch is for being drawn to ground through inclined shaft or vertical shaft from down-hole by mine car by rope traction.Winch is in service, often is used in the traction overload, causes the grave accidents such as wire cable rupture, winch damage, winch motor overload burning.At present also not for measuring in real time the device of winch operation tractive force.
In the inclined shaft ore deposit, winch is generally used for the traction track dolly and transports mineral.The operation of winch is generally sent instruction by down-hole and aboveground commanding, and hoistman is controlled the winch operation.Commanding and hoistman contact are generally with signal head or interphone.Hoistman has larger rashness in action to the running state of winch, and whether rail vehicle will arrive whether the traction of assigned address, winch transships, the running velocity of winch is how many etc., can only be by estimating or listening down-hole, well head commanding to command.When signal head fault or commanding's instruction slightly make mistakes, the operation of winch just there will be accident, and particularly the winch tractive load is excessive, and hoistman can not find in time yet, very easily causes winch to damage or the grave accident such as traction steel wire fracture of rope.
The utility model content
The utility model overcomes the deficiencies in the prior art, technical matters to be solved is, provide a kind of simple in structure, easy to operate, winch cable tractive force pressure sensitive monitoring device with low cost, can measure and show the numerical value of winch cable tractive force in real time, when tractive force surpasses setting value, can send warning, control the winch parking, to guarantee the winch safe in operation.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of winch cable tractive force pressure sensitive monitoring device, comprise shell, auxiliary wheel, force-measuring wheel, dynamometer link, pressure sensor, sensor outer housing, tractive force computing micro controller system and telltale, described two auxiliary wheels are arranged on enclosure, and the axis of two auxiliary wheels is parallel, steel rope runs through shell, and steel rope contacts with the top of two auxiliary wheels, described force-measuring wheel is between two auxiliary wheels, its bottom contacts with steel rope and to the lower compression steel rope, one end and the force-measuring wheel of dynamometer link are hinged, the outside that the other end of dynamometer link stretches out shell is positioned at the inside of sensor outer housing and withstands on the dynamometry end of pressure sensor, pressure sensor is fixed on the top of sensor outer housing, sensor outer housing is fixed on the top of shell,
Described pressure sensor mouth is connected with the input end of tractive force computing micro controller system;
Described tractive force computing micro controller system mouth is connected with the input end of telltale.
Described tractive force computing micro controller system is the ATmega16 micro controller system.
Described telltale is 1 group of 4 figure place code telltale, and bits per inch code pipe is 8 sections common anode utmost point charactrons.
The beneficial effect that compared to the prior art the utility model has is: the utility model has been realized the tractive force size of automatic monitoring winch cable with simple structure, cheap cost, thereby can judge that by the size of tractive force whether tractive force loads overload, and by controlling the acceleration magnitude of tractive force size adjustment winch operation, match with the monitoring regulator control system of speed, better monitor and regulate and control the running state of winch.The utility model is simple to operate, avoided greatly the blindness of artificial commander's winch operation, greatly reduced the accident risk of winch operation, actv. has guaranteed employee's personal safety and the property safety of enterprise, reduce employee's work capacity simultaneously, improved workmanship and efficiency.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is the utility model signal transmitting portions.
In figure, 1 is shell, and 2 is sensor outer housing, and 3 is pressure sensor, and 4 is dynamometer link, and 5 is force-measuring wheel, and 6 is auxiliary wheel, and 7 is steel rope.
The specific embodiment
As Fig. 1, shown in Fig. 2, a kind of winch cable tractive force pressure sensitive monitoring device, comprise shell 1, auxiliary wheel 6, force-measuring wheel 5, dynamometer link 4, pressure sensor 3, sensor outer housing 2, tractive force computing micro controller system and telltale, described two auxiliary wheels 6 are arranged on shell 1 inside, and the axis of two auxiliary wheels 6 is parallel, steel rope 7 runs through shell, and steel rope 7 contacts with the top of two auxiliary wheels 6, described force-measuring wheel 5 is between two auxiliary wheels 6, its bottom contacts with steel rope 7 and to lower compression steel rope 7, one end and the force-measuring wheel 5 of dynamometer link 4 are hinged, the outside that the other end of dynamometer link 4 stretches out shell 1 is positioned at the inside of sensor outer housing 2 and withstands on the dynamometry end of pressure sensor 3, pressure sensor 3 is fixed on the top of sensor outer housing 2, sensor outer housing 2 is fixed on the top of shell 1,
Described pressure sensor 3 mouths are connected with the input end of tractive force computing micro controller system;
Described tractive force computing micro controller system mouth is connected with the input end of telltale.
