The number of plies that pushes along with steel pipe successively descends, and pushing away beam 2 will successively reduce.Support arm 30 rotates around pivot pin, because the transition mark is a camber line under support arm 30 terminations, makes gradually from top to bottom to push away beam 2 and be moved to the left, and can make that to push away beam 2 position on every one deck comb inconsistent.The hydraulic cylinder of outside dolly 35 left end settings moves to overcome this phenomenon with regard to the push-and-pull dolly.

The dolly of pad pipe hoisting mechanism, push away beam and be used for the dolly of lifting at arm, respectively on arm in separately the slideway.

Among Figure 11, two independently the steel tube stacking district be arranged side by side in a side of cat road machine.Can share a transition frame between two steel tube stacking districts.

Controlling frame has split typely, and Contiuum type is also arranged.The split type of picture in the accompanying drawing.Also can the two corresponding arms of frame of controlling that install at two, steel tube stacking district be linked to be together, make two whole hanging beams.

For adapting to the height that pushes each layer steel pipe in the steel pipe process, the machine lifting of cat road, two kinds of modes of transition frame lifting are arranged.In " summary of the invention ", in order to narrate conveniently, directly carry out overall description as an example of the machine lifting of cat road example.In fact, the transition frame lifting some the time very convenient.Below, mainly be described as an example of the transition frame lifting example.

The specific embodiment

Steel pipe 1 is that drilling rod is stacked by Fig. 1, and installs frame 4, transition frame 3, the cat road machine 5 controlled.How each floor steel pipe of steel tube stacking district successively is pushed in " V " shape groove of cat road machine 5 by root, concentrates and narrate with Fig. 5.

Among Fig. 5, A figure, transition frame 3 has been elevated to and the top one deck pad pipe 6 concordant (more lower slightly).Push away card 11 and took in before this in the guide pipe 22, dolly 12 is from right to left walking before this.In the time of in the middle of pushing away the sharp semi circular surface facing to going up most between steel pipe 1 of row's rightmost and the adjacent steel pipe of card 11 cards, dolly parking (brake), be exactly present position among the figure, push away card 11 and under the effect of hydraulic cylinder 19, insert down by force, on the left side of the rightest above-mentioned steel pipe at once.At this moment, pipe clamp 20 bills on left side part is pulled under hydraulic cylinder 19 effects on the transition frame 3, is lower than transition frame 3 supporting plates 21 end faces.Subsequently, push away card 11 and push away steel pipe 1 in the pad pipe 6 edge transition frame 3 directions walking to the right of rolling, scheme referring to B.Dolly is gone to and is pushed away beam 2 terminations and stop, and pushes away card 11 and stops walking.Steel pipe 1 rolls in transition frame 3 middle " V " shape grooves because inertia continues to roll to the right, and is blocked by the pipe clamp 20 on the right on the transition frame 3, does not fall down.

Subsequently, transition frame 3 drops to the cat road machine 5 on the right flat.Such as C figure, the pipe clamp 20 on the right is retracted by hydraulic cylinder 19.The hydraulic cylinder 19 on transition frame 3 left sides is the top upwards, and the left side is raise, and steel pipe 1 is rolled in cat road machine 5 " V " the shape groove and goes at once.Next step is exactly that cat road machine 5 has independently been transported the thing of steel pipe to raised platform around a well.Subsequently, pushing away card 11 regains again in the guide pipe 22.Dolly to left side walking, repeats said process again.

To push away card and can accurately inject the steel pipe back that pushes away at every turn in order to make, be provided with especially exploration card 26.Because the place, well site can not be very flat, the pad pipe 6 of placement is probably high short on one side on one side again, and the high end of an end is short.Steel pipe is pushed away card and is promoted, and probably one is rolled very soon, and one slow, causes with former parallel lines tilting too much, has established especially block card 28, such as Fig. 6.

Among Fig. 6 A figure, push away card, block card all is recovered in the guide pipe.Exploration card 26 is under extension spring 25 effects, and lower checkpost point has rotated downwards, and top is against gear pier 24.At this moment, dolly 12 is to walk from right to left.When exploration card 26 touched a steel pipe 1 of rightmost, signaling switch 27 sent a signal to control system immediately.Control system on the one hand instruction dolly is stopped (brake), and the instruction hydraulic cylinder that pushes away card, block card moves on the one hand, makes and pushes away card, block card stretches out downwards.Pushing away card forces down by force along the arc surface (wiping the right steel pipe cambered surface) of following steel pipe.In this course, the right steel pipe is altered to the right immediately, is blocked by block card.Such as B figure among Fig. 6, steel pipe alters to the right that process does not draw.Subsequently, dolly is walked to the right, and rotate under Hydraulic Cylinder on exploration card top, and the bottom is all upwards regained and gone.Steel pipe rolls to the right pushing away between card and the block card.Scheme such as the C among Fig. 6.When dolly apart from push away termination, beam 2 the right also have suitably apart from the time, block card is just upwards regained in the guide pipe.Dolly continues right lateral, stops to pushing away the beam-ends head.Steel pipe rolls in cat road machine 5 " V " the shape groove because inertia also continues to roll at once.For reducing narration, save the transition frame said process, Fig. 6 directly draws cat road machine.

Pushing away the distance between the signaling switch 27 on card 11 and the exploration card, generally just is steel pipe 1 diameter.Become large such as diameter of steel tube, generally be no more than former steel pipe diameter 30%,, pushing away Ka Kajian is the inclined-plane, inserts down from pushing away steel pipe cambered surface again, can accomplish, and exploration card can swing to the right, and block card and push away larger distance is arranged again between the card can adapt to than big steel pipe and pushes.When pushing the larger diameter steel pipe, control system makes the piston rod of exploration card hydraulic cylinder stretch out a bit at the location-appropriate that originally shrank back, and can make the following signaling switch of exploration card and push away card apart from becoming large.Just can adapt to the more propelling movement of big steel pipe.

The cat road is confidential to be obtained on the raised platform around a well upwards transporting steel pipe after the instruction again.Subsequently, dolly is awaited orders to the suitable distance of left side walking.

Control frame and be installed in steel tube stacking district two ends.Push away beam on the steel pipe of discharging.For drawing clear (the too many pipe circle of termination, steel tube stacking district peaceful look like lines intensive among Fig. 1), the steel tube stacking district does not all draw in Fig. 7～10.Control base plate the right of frame against the pad pipe of having placed part in addition, it is following all will to be placed into the steel tube stacking district, referring to Fig. 9, Figure 10." wall " that the steel tube head in steel tube stacking district forms as a lot of circles.This together " wall " against clamp 38 by wire rope play can be smoothly up and down position, namely do not affect clamp up and down just.Pushing away beam and can also raise again among Fig. 8 is to desired location topmost.Go up row's steel pipe most and push away beam and only stays a little gap in the steel tube stacking district.By pushing away the distance of beam adjustment with the discharging steel pipe, do not contact steel pipe and be as the criterion to push away beam below.

Push away beam and push away in the steel pipe process, clamp is moved by the column direction of interior dolly 32 from inner slide 31 to shelf assembly 37.In the moving process, clamp is pulled on, and namely moves in steel pipe top, steel tube stacking district.Clamp in Figure 10 be moved to the left put in place after, wire rope puts down situation maps after some.In a word, when pushing away card work, clamp is abdicated the space, does not disturb.

Push away beam and push steel pipe by situation among Fig. 5, Fig. 6.When one deck steel pipe above the steel tube stacking district pushed complete after, two pad pipes just appear in steel tube stacking district topmost one deck.Subsequently, push away beam and just quit work, the space is abdicated in work to clamp.At this moment the hydraulic cylinder on the outer dolly left side pushes away outer dolly and moves right, shifts extreme position onto and stops, and top and the rear of pad pipe are available fully.Subsequently, clamp is lifted, and interior dolly is walked to the right.In the time of directly over going to the pad pipe, interior dolly stops.Clamp opens jaw, and wire rope slowly puts down clamp, over against the pad pipe.When the pad pipe enters jaw, when the top hits signaling switch in the jaw, this signaling switch sends a signal to control system at once, control system is the hydraulic cylinder action of instruction clamp at once, receive in the jaw and clamp pad pipe (not clamping), and the wire rope that dolly stops on the clamp immediately in the instruction descends.Subsequently, interior dolly is sling clamp together with the pad pipe.Until setting height, interior dolly is walking left on inner slide.When walking behind desired location, stop.Dolly begins slowly to put down clamp, pad pipe.After in the pad pipe descends, falling assigned position, stop.Because after clamp is clamped the pad pipe, appropriate gap is arranged, at this moment clamp continues, after putting in place, the pad pipe again hits signaling switch, and control system is after obtaining for the second time signal, and the instruction dolly stops to put down wire rope at once.Simultaneously, the hydraulic cylinder counteragent of instruction clamp opens jaw.Subsequently, dolly is awaited orders mentioning on the clamp such as Figure 10 position.Clamp is abdicated again the space and is started working to pushing away beam.

Subsequently, push away beam the hydraulic cylinder effect of the dolly left side is drop-down outside and go back, and readjust height and adapt with new " first row " steel pipe.Support arm middle part institute connected the hydraulic cylinder adjustment and pushed away depth of beam among Figure 10 before this, again by distance about the hydraulic cylinder adjustment on the outer dolly left side.Make and push away each time rise and fall of beam substantially at (error is as far as possible in 10 centimeters) on the same vertical line.Push away depth of beam with the wire rope adjustment among Fig. 8, only the hydraulic cylinder on the mobile outer dolly left side with regard to capable of regulating about distance.At last, the verticality that pushes away beam (it doesn't matter for a small amount of deviation, pushes away just that beam drops to lower position and degree perpendicular to the ground when differing too large, just is necessary adjustment) is adjusted in the hydraulic cylinder of supporting arm front end action.

Pad pipe hoisting mechanism independence handling pad pipe is take Fig. 9 as example.Among Fig. 9, be handling of clamp two pad pipes are placed on base plate and take on the piece, also in the situation of filling up pipe of slinging.

First pad pipe of clamp handling is placed on the base plate.Take piece and dropping under the hydraulic cylinder effect on this pad pipe for following first group subsequently.After second pad pipe put in place by handling, be placed on taking on the piece of having set level.Subsequently, one group of top is taken piece and is put down again and drop on second pad pipe.Clamp clamp the pad pipe after, rise first be raised to setting height after, interior dolly is walked left.Behind desired location, stop.Then, clamp falls, and puts down the pad pipe.

When getting drilling rod on the raised platform around a well, process is opposite with the top.Be from the steel tube stacking district bottom one deck pad pipe begin to discharge steel pipe.Bottom one deck pad pipe steel pipe heap above that send complete after, can not hang away.Cat road machine send steel pipe and gets off to push transition frame from raised platform around a well.Concordant with this one deck pad pipe after the transition frame lifting.Dolly has waited and has pushed away beam near this square end head of transition frame.In this process, push away card and block card uses conversely, push away card variable block card, block card becomes and pushes away card.Referring to Fig. 6, only to take here and push away card, exploration card, the original position of block card three, its each card motion changes and order, redescribes fully.1, push away card, block card and upwards regain guide pipe, the exploration card lower end is under the hydraulic cylinder effect, and upwards rotation is completely retracted into and pushes away more than the beam lower plane.2, the transition frame supporting plate left side is a little more than the pad pipe, and the right pipe clamp raises, and steel pipe " is fallen " on the pad pipe.Steel pipe is because inertia is managed the other direction rolling to pad.3, block card falls immediately, and exploration card also falls, and pushes away card and does not fall.Dolly is walking left immediately, and when catching up with this root steel pipe, the signaling switch on the exploration card gives a signal to control system, and the control system instruction pushes away card and falls.Simultaneously instruction exploration card inhour is rotated to get back to and is pushed away more than the following plane of beam.Like this, push away card and be used as block card usefulness, block card pushes away steel pipe to pad pipe other end appropriate location.Dolly stops, and pushes away card, the block card withdrawal is gone.Dolly is walking to the right again, repeats said process.After the discharging of first floor steel pipe is complete, push away beam and rise, abdicate the space to the operation of pad pipe hoisting mechanism.Clamp is clamped one of the top of the pad pipe of placing among Fig. 9 (at this moment having placed many pad pipes), rise, and walking to the right is to setpoint distance.Interior dolly stops.Clamp puts down the pad pipe.Push away beam and start working, until the discharging drilling rod is complete.The lifting of pad pipe has two kinds of modes, and a kind of is above-mentioned clamp lifting method, and another kind is magnetic force lifting method (not shown in FIG.).

Under the restriction of well site orographic condition, in the more situation of steel pipe specifications and models that maybe will push, can be arranged in machine side in cat road to two above steel tube stacking districts.Plural steel tube stacking district is arranged in cat road machine one side, and the transition frame of the steel pipe above the outside steel tube stacking district through the centre is rolled on the pad pipe of the steel tube stacking district the superiors placement near apart from cat road machine, pushes through pushing away beam, arrives transition frame, to cat road machine again.Followingly claim " square formation " a steel tube stacking district, such as Figure 11.Here claiming the first square formation by the steel tube stacking district of cat road machine direction, the left side be the second square formation.The steel pipe model specification of setting two square formations is different.The beam that pushes away of the first square formation is put row's steel pipe and row's pad is managed following lacking than the second square formation.If the steel pipe of the second square formation is pushed on the cat road machine, is sling two by the first square formation pad pipe hoisting mechanism and to fill up pipe and be placed on topmost on one deck steel pipe.If the pushed part of one deck steel pipe and reducing topmost then pushes 1～2 steel pipe again and puts well to appropriate location, termination, pad pipe the right by pushing away beam from the left side.Subsequently, hoisting mechanism hang two the pad pipes be placed on this row steel pipe on.This situation just among Figure 11.Steel pipe in the second square formation is pushed away beam and is pushed, and is rolled into through the lifting of middle transition frame on the pad pipe of the first square formation.The beam that pushes away of the first square formation namely pushes away this root steel pipe to the right transition frame, in cat road machine V-shaped groove.When needs push the specifications and models steel pipe of the first square formation, by pad pipe hoisting mechanism the top two pads pipes are hung out again.Namely recover the first square formation course of work in the past.

Above-mentioned control system refers to travel switch, signaling switch, relay switch in mainboard, each circuit etc., and with the relevant line of each component.More than in the narration, for simply, straight-line beginning with stop, the beginning of tumbler with stop, travel switch, signaling switch have all been installed in the place of all not mentioned travel switches, signaling switch.

Can only adapt to, finish picking of each floor steel pipe of steel tube stacking district with the machine lifting of cat road, pick each layer steel pipe with the machine lifting of cat road, machine both sides, cat road just do not arrange transition frame.

Without the well site of cat road machine, can directly deliver to assigned address to steel pipe with transition frame.

Be the part of power with hydraulic pressure, also available air pressure is power.

The full-automatic dispatch machine of drilling rod also applies to drilling rod manufacturing, workshop, and discharge and sends steel pipe the steel tube factory.
