Abstract
A kind of mine hoist card tank and sipping fault detection method, multiple magnetic lattices are equidistantly magnetized with along cage lifting direction on rigid cage guide surface, magnetic head and signal processing unit are installed at the top of cage.Changed by the alternating in magnetic field on magnetism-head detection rigid cage guide, the cage speed of service and displacement are converted into by signal processing unit.With reference to the encoder on reel and the depth indicator information being placed in Central Control Room, judge that mine hoist whether there is card tank and sipping fault.The present invention is simple in construction, easy for installation, and reliability is high, can accurately detect the card tank and sipping fault of mine hoist in real time.
Description
Technical field
The present invention relates to it is a kind of detect mine hoist running status method, particularly a kind of mine hoist card tank and
Sipping fault detection method.
Background technology
Mine hoist is the large-scale and complicated device for being applied to vertical production, undertakes and lifts coal, spoil, lower putting material,
Lifts personnel and the task of equipment, it is referred to as " throat of mining production ", the safety that its running status is directly connected to mine is raw
Production.But card tank and sipping fault happen occasionally in elevator running, the lighter causes maintenance down, influences coal production
And yield, severe one can occur disconnected rope falling accident, cause huge economic losses and great casualties.
The content of the invention
Technical problem：It is an object of the invention to provide one kind can accurately detect mine hoist card tank and skidding event in real time
The method of barrier.
Technical scheme：The mine hoist card tank and sipping fault detection method of the present invention, including rigid cage guide, are arranged on
Magnetic head and signal processing unit at the top of cage, the encoder on reel, the industrial computer being placed in Central Control Room and depth
Spend indicator, magnetic head and signal processing unit electrical connection.Described rigid cage guide is equidistantly magnetized with along cage lifting direction
Multiple magnetic lattices.In cage running, the alternating change in magnetic field, is changed by signal processing unit on magnetism-head detection rigid cage guide
It is counted as the speed of service of cageAnd displacement, and it is sent to by wireless signal the industrial computer in Central Control Room.
A. described encoder gathers reel rotary speed and sends industrial computer to, and industrial computer obtains reel by conversion and gone out
Rope speed, whenAndWhen, mine hoist there may be card tank failure；
B. the displacement of described depth indicator collection cage operationAnd send industrial computer to, whenWhen, mine hoist
It there may be sipping fault.
Beneficial effect：The present invention accurately calculates the speed of service of cage using the changes of magnetic field of magnetic lattices on rigid cage guide
And displacement, can be effective in real time with reference to the encoder on reel and the depth indicator information being placed in Central Control Room
Judge that mine hoist whether there is card tank and sipping fault, and it is simple in construction, easy for installation, reliability is high.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the signal processing unit block diagram of the present invention.
In figure：1-rigid cage guide, 2-magnetic head, 3-signal processing unit.
Embodiment
One embodiment of the present of invention is further described below in conjunction with the accompanying drawings：
As shown in figure 1, the mine hoist card tank and sipping fault detection method of the present invention, including along between cage lifting direction etc.
Away from the rigid cage guide 1 for being magnetized with multiple magnetic lattices, magnetic head 2 and signal processing unit 3 at the top of cage, magnetic head 2 and letter
Number processing unit 3 is electrically connected.Encoder is arranged on reel, and industrial computer and depth indicator are placed in Central Control Room.Signal
Processing unit 3 includes filter amplification circuit, processor and wireless transmission chip, as shown in Figure 2.In cage running, magnetic
The alternating change in magnetic field, the filtered amplifying circuit of signal that magnetic head 2 exports are amplified into processing on first 2 detection rigid cage guide 1
Device, the speed of service of cage is converted into by processorAnd displacement, and it is sent to by wireless transmission chip the work in Central Control Room
Control machine.
A. encoder gathers reel rotary speed and sends industrial computer to, and industrial computer obtains reel by conversion and goes out rope speed, whenAndWhen, mine hoist there may be card tank failure；
B. the displacement of depth indicator collection cage operationAnd send industrial computer to, whenWhen, mine hoist may be deposited
In sipping fault.
