Description
Technical field
The invention belongs to plant equipment control technology field, for the automatic emergency brake in drive failure, relates to
And it is a kind of based on speed than to boring winch automatic braking protective device, the invention further relates to based on speed than to rig strand
Car self-actuating brake guard method.
Background technology
At present, oil-well rig has been equipped with winch disc brake braking mechanism to realize effective protection of rig lifting device position
Control；And the automatic brake functions of partial status can also be realized based on PLC automatic control technologys, such as frequency converter failure, are led to
Interrogate the self-actuating brake under the states such as failure.
But for being equipped with the rig of more spotting hoists or independent automatic driller, when main motor gearshift or certainly
Dynamic Song Zuanguahe mechanisms go wrong, and when power can not be transferred on winch drum lifting device, how quick disc brake system is
Automatically devote oneself to work, prevent " drilling string not well braked " accident from occurring, not yet effectively solved at present.
The content of the invention
It is an object of the invention to provide it is a kind of based on speed than to boring winch automatic braking protective device, solve
After prior art boring winch main motor gearshift or automatic bit feed hang conjunction mechanism-trouble, disc brake system can not realize automatic throwing
Enter work, the problem of security of system deficiency.
It is a further object of the present invention to provide it is a kind of based on speed than to boring winch self-actuating brake guard method.
The technical solution adopted by the present invention is, it is a kind of based on speed than to boring winch automatic braking protective device, bag

Embodiment
The present invention is described in detail with reference to the accompanying drawings and detailed description.
Reference picture 1, the structure of multi gear winch driving gear is used by the inventive method, including main motor 7, main motor
7 are connected by first shaft coupling selector 10 electronic with reduction box, and the electronic selector 10 of reduction box passes through second shaft coupling
It is connected with roller 9, the both ends of roller 9 are provided with disc brake mechanism, and each disc brake mechanism connects with disc brake hydraulic-pneumatic control valve group 3
It is logical；The electronic selector 10 of reduction box also bores clutch 11 by electric feeding and is connected with automatic bit feed motor 8；In main motor 7
Shaft end is provided with mair motor encoder 1, and roller encoder 2 is provided with the shaft end of roller 9, is installed in the shaft end of automatic bit feed motor 8
There are automatic bit feed encoder 4, the letter of mair motor encoder 1, roller encoder 2, automatic bit feed encoder 4 with PLC 5
The connection of number input, a signal output part of PLC 5 are connected with driller's operating display 6, PLC 5 it is another
Individual signal output part connects with the control of disc brake hydraulic-pneumatic control valve group 3.
PLC 5 is not required to individually be equipped with, and can be shared with the PLC in conventional drill, only by the above-mentioned preset control of method
Program.
In above-mentioned multi gear winch driving gear, by the electronic selector 10 of reduction box by motor when main motor 7 works
Output speed is delivered on the roller 9 of winch with different speed reducing ratio, wherein when the electronic selector 10 of reduction box is operated in location A
When, it is low or first gear, speed reducing ratio iIt is low；It is neutral when the electronic selector 10 of reduction box is operated in B location, the power output of main motor 7
Square can not be delivered on roller 9, realize the disengaging with roller 9；When the electronic selector 10 of reduction box is operated in location of C, for height
Fast shelves, speed reducing ratio iIt is high；In the winch equipped with automatic bit feed motor, when automatic bit feed motor 8 works, now main motor 7
Do not work, the extension conjunction of clutch 11 is bored by electric feeding or separation is realized between the output speed of automatic bit feed motor 8 and roller 9
Transmit or depart from, wherein when electric feeding bores clutch 11 and is operated in D positions, automatic bit feed motor 8 and the electronic gearshift of reduction box
Device 10 departs from, and the torque of automatic bit feed motor 8 can not be delivered on roller 9, realizes the disengaging with roller 9；When electric feeding bore from
When clutch 11 is operated in E positions, automatic bit feed motor 8 is hung with the electronic selector 10 of reduction box and closed, and automatic bit feed motor 8 is with deceleration
Compare iSend brillRotating speed is delivered on the roller 9 of winch.
The method of the present invention, the rotary speed for detecting current main motor 7 using mair motor encoder 1 are supplied to PLC to control
Device 5 processed, the actual rotation speed of roller 9 that current winch is detected using roller encoder 2 are supplied to PLC 5, using automatic
Send brill encoder 4 to detect the current actual rotation speed of automatic bit feed motor 8 and be supplied to PLC 5, PLC 5 is according to behaviour
Go out the motor type and its deceleration gear box of currently practical work as command recognition, while PLC 5 rotates main motor 7
Speed or the rotary speed of automatic bit feed motor 8 calculate the drum rotation speed of theory by software program.Under normal circumstances, the theory
Drum rotation speed and roller encoder 2 to detect the actual rotation of obtained current roller fast basically identical, when equipment breaks down
The two rotating speed difference is larger, and now PLC 5 sends control instruction to disc brake hydraulic-pneumatic control valve group 3 automatically, so as to control panel
Brake mechanism realizes self-actuating brake；5 automatic alert of PLC reminds operator to driller's operating display 6 simultaneously
