Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, can be seen that from figure, the present invention logs well inserting tube radioactive source handling chuck clamps, including base 1 be located on base rotating vertical rotating shaft, is provided with, between base and vertical rotating shaft, the transmitting balls or bearing that make rotation smooth. The rotary chuck gear 2 of level it is fixed with in rotating shaft upper end; Being provided with rotating stepper motor 3 on base 1, rotating stepper motor 3 engages to drive rotary chuck gear and axis of rotation with rotary chuck gear 2 by drive bevel gear 4.
Rotary chuck gear 2 is provided with clamp seat 5, clamp seat 5 upper surface is provided with two relative clamps 6 by slide rail, two clamps 6 are connected with clamping motor 7 respectively, clamping motor 7 drive clamp 6 along slide rail move toward one another to be clamped by well logging inserting tube or to move dorsad to unclamp well logging inserting tube respectively.
Be provided with over brace 8 on base 1 or on clamp seat, over brace 8 be provided with rotating bearing pin 9, cross bar 10 is fixing with bearing pin 9 is connected with bearing pin synchronous axial system, cross bar is positioned at above clamp to be limited the position of inserting tube door of logging well by cross bar. Being provided with cross bar motor 11 on over brace 8, cross bar motor 11 is connected to drive bearing pin to rotate with bearing pin 9. Being provided with the playback travel switch 12 and limitation travel switch 13 that limit cross bar turned position on over brace 8, playback travel switch 12 and limitation travel switch 13 are connected with cross bar motor 11.
Based on the difference of radioactive source, practical logging inserting tube has the two kinds of calibers varied in size, and clamp designs based on little well logging inserting tube, and namely little well logging inserting tube can be clamped relatively tight by clamp. But when clamping big well logging inserting tube, two clamps cannot be of completely closed, when clamping big well logging inserting tube, between clamp, exist for gap. If this gap is not hidden, it is possible to there will be some drop thing and by gap continue toward fall, thus potential potential safety hazard served by band. For this, the present invention is provided with corresponding structure on clamp and prevents. Specific as follows: to be respectively equipped with bearing 14 at two clamp 6 upper surfaces, bearing 14 is provided with two and is generally aligned in the same plane and parallel buffering clipper joint arm 15, buffering pincers 16 are sleeved on two buffering clipper joint arms 15 and can slide laterally along buffering clipper joint arm 15, buffering pincers on two bearings are oppositely arranged and are formed when closing up one by the passage of big well logging inserting tube laminating clamping, can be respectively installed with buffer spring 17 on two buffering clipper joint arms 15 between bearing and buffering pincers. Namely clamp 6 based on pipe with small pipe diameter log well inserting tube and design, buffering pincers 16 based on Large Diameter Pipeline log well inserting tube and design, clamp pipe with small pipe diameter well logging inserting tube time, although two buffering pincers close up, but can not clamp pipe with small pipe diameter well logging inserting tube, namely inoperative. When clamping Large Diameter Pipeline well logging inserting tube, clamp and buffering pincers work simultaneously, and clamp mainly provides chucking power, and buffering pincers mainly realize closure function and form a cover-up surface.
In order to avoid metal clamp directly contacts, with well logging inserting tube surface, the damage being likely to well logging inserting tube, the present invention is provided with rubber layer 18 in the obvolvent face of two clamp obvolvents well logging inserting tubes.Rubber layer 18, except protection well logging inserting tube, owing to contact surface frictional force increases, therefore also has the effect increasing cohesive force, it is achieved more reliable obvolvent.
Operation principle of the present invention and process:
1, clamp is separately: first two clamping motors work simultaneously and drive two clamps to move dorsad along slide rail respectively, make two clamps open up into maximum rating, and two buffering pincers also synchronize separately.
2, clamping well logging inserting tube: again well logging inserting tube is put into the folder thing passage that two clamps and two cushion between pincers, two clamping motor transmissions make two clamp move toward one another be clamped by well logging inserting tube. Buffering pincers automatically close up (if big well logging inserting tube is then by its obvolvent and generation very close to each other, to stop that the thing that drops continues to fall) under the effect of buffer spring.
3, well logging inserting tube rotate in place: after well logging inserting tube is held tightly, rotating stepper motor work drives rotary chuck pinion rotation, rotary chuck gear driven well logging inserting tube horizontal direction left rotation and right rotation, stopping after reaching position set in advance, this position just facilitates mechanical hand switch door and handling radioactive source.
Confirm that well logging inserting tube is rotated in place by the mark line finished in advance in picture control picture in computer.
Next it is exactly storehouse door opening, puts into or take out radioactive source, finally close door. Owing to radioactive source has two kinds, corresponding well logging inserting tube also has two kinds, and the bin gate structure of two kinds of well logging inserting tubes is different. A kind of door carries opens spring, namely when closed without stubborn screw, owing to the elastic force effect of spring also can be opened voluntarily, therefore needs to withstand with cross bar when switching door, then by machinery hand screw. Another kind of door is then absent from this situation. Carry out the explanation of switch door separately below.
Door carries switch door action during spring:
4, open a position: the work of cross bar motor drives beam movement, touch stop motion during limitation travel switch, now cross bar in-position II, this position just props up the door of Guan Bi, and then mechanical hand is return after unscrewing the screw on door, and cross bar returns to initial position (position I, controlled by playback travel switch), because the effect of door spring, now door automatically springs open and falls open maximum angle, completes the work that opens a position of well logging inserting tube;
5, the handling of radioactive source: radioactive source is loaded well logging inserting tube door or takes out radioactive source from well logging inserting tube by mechanical hand;
6, Guan Cang: after well logging inserting tube door is closed certain angle (between closing and fully opening) by manipulator behavior, the work of cross bar motor drives beam movement, touch stop motion during limitation travel switch, now cross bar in-position II, door is pushed away toward closing direction and is just closed by door when position II in motor process by cross bar, cross bar keeps this position, well logging inserting tube door screw is tightened again by mechanical hand, then cross bar returns to initial position (position I), is finally completed door and closes.
Switch door action when door is without spring:
4, open a position: the work of cross bar motor drives beam movement, allows cross bar playback initial position; Generally cargo handling process all can have cross bar playback instruction every time.
(position III is certain position between closing and fully opening in in-position III, position III is preset realization by software), then mechanical hand drives well logging inserting tube door to move to cross bar stop position III after unscrewing the screw on door, cross bar blocks well logging inserting tube door with robot movement, mechanical hand departs from well logging inserting tube door, then cross bar returns to initial position (position I), because door action of gravity, door automatically opens up maximum angle, and mechanical hand completes the work that opens a position of well logging inserting tube;
5, the handling of radioactive source: radioactive source is loaded well logging inserting tube door or takes out from well logging inserting tube by mechanical hand.
6, Guan Cang: well logging inserting tube door is pushed into and completely closes by manipulator behavior, well logging inserting tube door screw tightened by mechanical hand, completes door and closes. Owing to this door blocks door when closing up even without cross bar, door also can be closed reliably, will not automatically open up door, so mechanical hand can back out the work carrying out tightening screw, now need not coordinate by cross bar, and cross bar remains in initial position.
After door is closed, clamping motor makes two clamps back out, and well logging inserting tube is taken out by boat car again from fixture.
