The concrete enforcement of detection ring 3 can be adopted the scheme of multiple form of structure, as follows near the form structure that switch measures signal as employing: detection ring 3 is by outer shroud 14, interior ring 15, connecting rod 19, second near switch 16 compositions, interior ring 15 is positioned at outer shroud 14, outer shroud 14 is fixedlyed connected by connecting rod 19 with interior ring 15, interior ring 15 is provided with second near the switch exploration hole, be fixed with second on the outer shroud 14 (as shown in Figure 6 near switch 16, it is 4, be evenly distributed on the circumference of outer shroud), second detecting head near switch 16 is positioned at second on the ring 15 near the switch exploration hole.Be installed in parallel 4 often open function second near switch 16, its purpose is when circulator 1 enters detection ring 3, second sends the signal of conducting near switch 16.Interior ring 15 is used to prevent that wire rope and circulator from breaking second near switch 16.
The above detection ring 3 and first is contactless near switch 10, the working condition when its purpose is in time to detect the drilling rod lifting.Drilling rod is made up of outermost layer drilling rod 5, intermediate layer drilling rod 6, center drilling rod 7.According to the polarity of ground of rotary drilling rig circuit the direction of the first diode D1 and the second diode D2 is set, when first being conducting direction near switch 16 when closed near switch 10 and second.
Operating principle:
Feature when the utility model has utilized " extension drilling rod ": circulator 1 and centre drill club head 2 do not come out from the top of arbitrary-movement articulator 4, and just whole upwards lifting of frozen drill pipe left spring buffer 12, sees the state of Fig. 3.A detection ring 3 is set on arbitrary-movement articulator 4, after circulator 1 or centre drill club head 2 enter detection ring 3, sends signal; Above unit head 13, be provided with one first and be used to detect the position of drilling rod flange 8, send connection signal during near the induction zone of switch 10, see Fig. 2 when drilling rod flange 8 enters first near switch 10.
Fig. 2 is that drilling rod is unrecovered, and drilling rod flange 8 drops on and promotes normal lifting state on the spring buffer 12.Fig. 3 all regains for drilling rod, and circulator 1 or centre drill club head 2 enter detection ring 3, the normal lifting state that drilling rod flange 8 begins to leave; Fig. 4 is that drilling rod is unrecovered, and circulator 1 or centre drill club head 2 fail to enter detection ring 3, and drilling rod flange 8 leaves the spring buffer 12 and first induction zone near switch 10, the state of " extension drilling rod " accident sign occurs.
According to above motion feature, detection ring 3 or first just thinks that near switch 10 any one Continuity signal that send drilling rod is in normal condition; If two groups all do not have Continuity signal, illustrate that the phenomenon of " extension drilling rod " has appearred in drilling rod.According to these signals, realize the operation of warning and cut-out dangerous play by the control warning circuit.
In addition, increased by a cover self-checking circuit in the design of control warning circuit, put in place when the center drilling rod has normally just promoted, detection ring 3 and first is near switch 10 conductings simultaneously, and the self check lamp is bright; Drilling rod further promotes, and drilling rod flange 8 leaves first near after the switch 10, and the self check lamp extinguishes automatically, if when external circuit has a place short circuit to occur, the long-term bright indication of self check lamp will occur, reminds the operator to find the fault of this device.
The operating principle of warning and self check and effect are as follows:
During normal lifting state: first near switch 10 or second during near switch 16 any conducting, coil K3 gets, normally closed interlock K3/2 and constant close contact disconnect, red led H2 and alarm buzzer E1 dead electricity are not sent signal, normally closed interlock K3/1 and constant open contact conducting, green indicating lamp H1 gets electric, and the hydraulic buttery valve that out-put supply makes the control drilling rod rise must conduct, show working properlyly, can carry out the vertical motion of drilling rod.
When occur hanging the drilling rod state: first near switch 10 or second near switch 16 all during not conducting, normally closed interlock K3/1 and constant close contact conducting, red led H2 and alarm buzzer E1 get the electric alarm signal of sending; Normally open contact K3/1 and constant open contact disconnect simultaneously, cut off the hydraulic buttery valve outage that out-put supply (being output port T) makes that the control drilling rod rises, and stop the lifting action of drilling rod.
Self check state: in normal operating conditions, first near switch 10 and second near 16 most times of switch are respectively conductings, coil K1 and coil K2 respectively electric, normally open contact K1/1 and constant open contact, normally open contact K2/1 and constant open contact are connected, and indicator lamp H3 does not work; When drilling rod is just all regained, circulator 1 enters in the detection range of detection ring 3, drilling rod flange 8 does not leave first during near switch 10 as yet, first near switch 10 and second near switch 16 conductings simultaneously, normally open contact K1/1 and constant open contact and normally open contact K2/1 and constant open contact are connected simultaneously, and indicator lamp H3 is shinny, continue to promote, second near switch 16 disconnections, and indicator lamp H3 extinguishes.In like manner also can once above-mentioned process in the decline process.In each working cycles up and down, if the utility model device is working properly, self check yellow indicator lamp H3 has twice flicker like this.If indicator lamp H3 is flicker not, and is shinny always in the perhaps a certain action, illustrate fault to have occurred, need maintenance.
