Embodiment
Below in conjunction with accompanying drawing the embodiment of the invention is further described:
This bi-dimensional pipe interface angle cutting control device is installed on the pipeline 14 that needs cutting, and entire mechanism is made of travelling mechanism and tooth bar travel mechanism.At first the mechanical movement mechanism to this control device describes:
Travelling mechanism: operation has a walking dolly 7 on pipeline, and this walking dolly moves on pipeline by running wheel 5 of front portion and two guiding wheels 12 at rear portion.The wheel that wherein leads is walked on the flexible rail 15 that is provided with in advance on the pipeline, to guarantee the hoop walking precision of walking dolly.On walking dolly, be fixed with delegation and walk motor 10 by its installing plate that installs 8, the speed reduction unit of this movable motor (is installed with the movable motor one, do not have label) output shaft on an engageable sprocket wheel (not having label) that is wrapped in the chain 13 on the pipeline disc is installed, by the driving of movable motor, realize the hoop walking of travelling mechanism by the sprocket wheel chain.On movable motor, be fixed with a control enclosure 11 (this control enclosure also can be packed in travelling mechanism Anywhere) and an angular transducer 9.Control circuit is installed in the control enclosure.
Tooth bar travel mechanism: on walking dolly, install a back up pad 6, this back up pad installs a tooth bar 1, one tooth bar travel mechanism is installed on this tooth bar, this tooth bar travel mechanism by the stepper motor of installing on installing plate 3, the installing plate 4 (comprising speed reduction unit), a burning torch 2 be installed below installing plate constitute.Stepper motor is realized the walking of installing plate on tooth bar by the gear (not shown) of driving engagement tooth bar, because stepper motor is simple known technology by the gear drive tooth bar of installing on its output shaft, does not provide concrete technology in the present embodiment in detail and constitute.The principle of work of tooth bar travel mechanism is: by the driving of stepper motor, making installing plate drive burning torch walks on tooth bar, because stepper motor is by the Single-chip Controlling in the control enclosure, single-chip microcomputer is by pipe diameter parameter and the angle parameter and the correlation parameter of the input of control enclosure panel, calculate the axial displacement of stepper motor through single-chip microcomputer by the angular transducer transmission signals, the walk axial displacement of appointment of Micro Controller Unit (MCU) driving stepper motor, when treating that stepper motor is walked 180 ° of pole locations of pipeline to be cut by initial point position, the Single-chip Controlling stepper motor returns walking, drives burning torch and cuts out a cut surface that has angle.This stepper motor can with walking dolly synchronous operation, can realize having the pipeline cutting of the cut surface of angle; Single-chip microcomputer can not carry out independent walking by the control step motor yet, can realize the radial cuts of pipeline.
Control circuit in the control enclosure partly is:
The control circuit of native system is installed in the control enclosure, this control circuit is implemented control by the MCS51 series monolithic, but this single-chip microcomputer is by the button input channel diameter parameters and angle parameter and relevant of control enclosure panel, and the parameter values of input and duty can be shown by LED nixie display on the control enclosure panel or liquid crystal LCD display.By the axial displacement that calculates stepper motor of angular transducer transferring input signal by single-chip microcomputer, this displacement is by the walk axial displacement of appointment of Micro Controller Unit (MCU) driving stepper motor.
Control circuit is made of single-chip microcomputer, 8 A/D D/A converting circuits, sensor shaping circuit, burning torch testing circuit, button input display circuits, and the special purpose interface of this single-chip microcomputer connects foregoing circuit and stepper motor respectively.Because single-chip microcomputer, A/D D/A converting circuit, button input display circuit and annexation are current techique, so present embodiment repeats no more, and only just innovation circuit is partly narrated.
The sensor shaping circuit:
Single-chip microcomputer connects sensor shaping circuit, this shaping circuit connection angle sensor by the A/D change-over circuit.Because the signal of angular transducer is more weak, therefore needs the sensor shaping circuit to strengthen this signal, and this signal is carried out shaping.Constituting of sensor shaping circuit: angular transducer is connected an operational amplification circuit that is made of resistance R 2, R3, operational amplifier ZA by resistance R 4 with stabilivolt Z1, this operational amplification circuit is connected with the A/D change-over circuit by the pressure filter circuit that is made of resistance R 1, potentiometer P1 and capacitor C 1.
The burning torch testing circuit:
The input end of burning torch testing circuit respectively with burning torch be cut pipeline and be connected, gather the burning torch working signal.Because this working signal is more noisy, and the control to single-chip microcomputer causes interference easily, therefore need isolate filtration to this working signal.This circuit adopt for connecting burning torch respectively and be cut two photoelectrical coupler G1, G2 of pipeline, the working signal of burning torch is filtered shaping, be beneficial to the operate as normal of single-chip microcomputer.Resistance R 5 in the circuit has been the metalfilmresistor of metering function.
Principle of work of the present invention is: by pipe diameter parameter and the angle parameter and the correlation parameter of button input, these parameters are given single-chip microcomputer by the angular transducer transmission signals, and single-chip microcomputer carries out computing to transmission signals; Receive the burning torch working signal of burning torch testing circuit at single-chip microcomputer after, the signal of single-chip microcomputer after with computing is transferred to stepper motor, and drive stepping motor drives the walk axial displacement of regulation of burning torch (burning torch is in running order).After stepper motor arrival was cut the limit of pipeline, the Micro Controller Unit (MCU) driving stepper motor returned axial displacement, has so just realized the cutting to the angular cutting face that is cut pipeline.
