Description

Monoslinger drill-drawing protector

The utility model is a kind of safety detection device that is applied in the two suspender liftings of the one-tenth that tangles load from both sides, as is applied in the process of rig lifting drilling tool.

In production and construction, adopt two suspension ring liftings commonplace, for example in the normal trip-out process of rig, should be enclosed within the down-hole equipment of slinging on the anchor clamps simultaneously by two suspension ring, but in operating process, might produce the phenomenon that single-ring rises, cause serious industrial accident thus.Do not prevent the safety device of single-suspender rig down on the existing rig, the situation that detects single-suspender rig down mainly is to lean on the observation of human eye to judge, and this can not prevent the generation of accident timely and effectively.

The purpose of this utility model provides a kind of safety detection device that is used to prevent the single-ring lifting, this safety device is a kind of radio robot, it comprises: tilt signals detecting device, the power supply step switch that is associated with the energy disperser action on lifting thing object, the projector of radio robot, receiving actuator four parts of radio robot are formed.

Concrete solution of the present utility model is: be provided with a power supply step switch at the energy disperser position of lifting appliance, the closure of power supply step switch is associated with the action of energy disperser; The suspension hook of lifting appliance is provided with a tilt signals detecting device, the power supply step switch is discerned the signal of single-ring lifting with the tilt signals detecting device, the signal that identifies is transmitted by the projector of radio robot, report to the police by the receiving actuator of radio robot again and cut off the lifting object the control access.

Accompanying drawing 1 is that tilt signals detecting device and power supply step switch are installed in the position view on the lifting appliance.

Accompanying drawing 2 is structural representations of tilt signals detecting device.

Accompanying drawing 3 is radio robot projector functional block diagrams.

Accompanying drawing 4 is radio robot receiving actuator functional block diagrams.

Accompanying drawing 5 is physical circuit figure of radio robot projector.

Accompanying drawing 6 is physical circuit figure of radio robot receiving actuator.

Do to describe in detail below in conjunction with accompanying drawing: from accompanying drawing 1 scheme of installation of power supply step switch 1 and tilt signals detecting device 2 as can be seen.Pulley at the lifting object is equipped with energy disperser 34 times, and the power supply step switch 1 that a control radio robot starts is housed between energy disperser 3 and the suspension hook 5, and the closure of power supply step switch 1 is associated with the action of energy disperser 3; The tilt signals detecting device 2 of a horizontal positioned is housed on suspension hook 5, and the below of suspension hook 5 is two suspension ring 6.

What accompanying drawing 2 was described is tilt signals detecting device structural representation, and as can be seen from Figure 2 the left and right end portions of the seal chamber of tilt signals detecting device is equipped with two groups of

adjustable metal electrodes

12,14 up and down.The liquid that is equipped with in the cavity accounts for 50% of volume, and liquid can be mercury or the lower liquid of other solidfying point.Between

adjustable metal electrode

12,14 and the cavity with insulating material 13 insulation, above in one group electrode 12 and the projector A end of instruction signal generator 32 circuit link; Below one group the B end of electrode 14 and instruction signal generator circuit link, this coupling method is in order to satisfy suspension hook both sides to tilt to the left and right respectively, the needs that circuit can detect this signal.

Accompanying drawing 3, that accompanying drawing 5 is described is radio robot transmitter circuit block diagram and physical circuit figure, as can be seen from the figure transmitter circuit is by standard signal frequency generator 31, command signal generator 32,

differential circuit

33,34, summitor 35, width fixing device 36 is transferred amplifier 37, and the output stage circuit 40 of intermediate amplifier 39, oscillator 38 and band antenna constitutes.The two arrays of electrodes up and down 12,14 that two A of command signal generator 32, B input end are connected to tilt signals detecting device 2 respectively, when tilt signals produced, this circuit was held conducting by AB, made command signal output; The physical circuit of the various piece that accompanying drawing 5 provides is the commonality known circuits except that command generator circuit 32 and electric quantity of power supply detecting device 7, the utility model is no longer described in detail, narrate the working process of transmitter circuit below: standard-frequency signal producer 31 generation width are the square-wave signal about 20MS, for satisfying the needs of modulated high frequency signal,

differential circuit

33,34 become square-wave signal into the pointed pulse signal output, summitor 35 carries out gating to the sharp arteries and veins signal that input comes, negative pointed pulse by gating after, become the impulse singla of certain width through width fixing device 36, after process modulated amplifier 37 is modulated amplification, be used for middle amplifying stage 39 with local oscillator 38 combineds action and form high-frequency carrier signals, go out through the wireless transmission of output stage circuit 40.By electric quantity of power supply detecting device 7, can carry out cross-check sum to electric quantity of power supply at any time and guarantee normal operation.

Accompanying drawing 4 and accompanying drawing 6 are receiving actuator circuit diagrams of radio robot.This part circuit includes and receives high frequency circuit 41 as can be seen from circuit block diagram, signal modulation circuit 42, multistage amplifier 43, rectifying circuit 44, power amplifier 45 and and be connected with actuating unit 46 and warning circuit 47 and power sense circuit 48.More than each circuit remove actuating unit 46, annunciator 47 is public circuit beyond the Power supply detector 48.The working process of this circuit is as follows: high-frequency oscillating circuits 41 receives and transmits the carrier signal of coming, and utilize high-frequency oscillating circuits to make it reduction, but the signal of high-frequency oscillating circuits 41 outputs still can not directly be imported actuating unit, also must high-frequency signal be modulated into low frequency signal by modulation circuit 42, low frequency signal after the modulation obtains direct-flow output signal through rectifying circuit 44 after multi-stage power amplifier 43 amplifies.In order to satisfy the needs of actuating unit electromagnetic valve 46 and warning circuit 47, after the direct current signal of rectifying circuit 44 outputs must carry out power gain by a power amplifier 45, drive actuating unit 46 and warning circuit 47 work, can detect electric quantity of power supply at any time by electric quantity of power supply detecting device 48, to guarantee normal operation.

Concrete implementation process: when rig does not pull out of hole, buffering 3 on the rig pulley is failure to actuate, the power supply step switch disconnects, this moment the safety device radiating portion power-circuit breaking, the circuit of a whole set of beeper is not worked, even tilt signals detecting device 2 has tilt phenomenon also will not detect simultaneously.When rig pulls out of hole, energy disperser 3 actions, through behind the LAP, power supply step switch 1 closure.Power connection, safety device radiating portion and reception operating part are in and give mode of operation fully, when tilt signals produces, detecting device 2 passes the feedway of detected signal by radio robot immediately, the reception operating part of radio robot was reported to the police the signal that receives and was cut off the electromagnetic valve 46 of control access this moment, thereby the accident that has prevented single-suspender rig down takes place.
