A kind of mechanism of walking certainly of whole movement oil-well rig main computer unit
Technical field
The utility model belongs to a kind of transportation equipment of oil drilling and extracting equipment, and is particularly a kind of in the in running order walking mechanism of carrying out whole movement down of drill main body parts.
Background technology
Petroleum industry with the rig of various models experienced by machine dimensions drill to electric drilling machine, direct current drive rig after the development of AC frequency conversion electric drilling machine, reached a stage that can meet drilling technology and modern industry production requirement, comparatively speaking, the frequent removal of home of rig and then more and more obvious in petroleum drilling operation by the high expense that produced of removal of home, so the removal of home performance of rig becomes the another bottleneck that influence the whole advance of rig.
At present, what rig was moved roughly can be divided into two kinds in form, and a kind of is that drill main body is splitted into a plurality of individual components, transports with flat car then.Like this, the rig of 5000-7000 rice removal of home roughly needs the freight volume of 130 train numbers, and because the dismounting and the entrucking length consuming time of rig, so even also at least will be with 7-10 days time under the very near situation of the distance of removal of home.
Another kind is to pull rig, pull rig and can be divided into again that integral body is pulled rig and two kinds of forms of rig are pulled in split, the realization that integral body is pulled mode is by train wheel apparatus is linked to each other with base through gooseneck structure, therefore the drill main body equipment that base connected is not torn open except that liquid, gas, water pipeline and cable substantially, but incidental disconnected equipment thribble need resolve into drilling rod and is thrown under the platform on the base, transfer base then to low level, keep the derrick erectility to carry out whole movement, as shown in Figure 1.
This rig idol of pulling form has several examples, and there is following shortcoming in it:
1. this whole movement mode is had relatively high expectations to road, to guarantee the stability of delivery unit.
2. the pattern that turns to of huge delivery unit and machinery makes its turning radius very big.
3. this means of transportation all needs to get rid of single in the operation of each removal of home and makes up a joint and waits repetition and insignificant work, and not only labour intensity is big, and length consuming time.
4. this whole movement often needs the next also car of tractor more than two to drag the difficulty of the asynchronism of while many tractors and the waste that the deviation on the direction all can cause power resource and increase transportation greatly because of overall weight.
5. this power traction mode makes the mobile very flexible of drill main body equipment, therefore aims at difficulty of well head.
Split is pulled rig and is meant and is divided into two delivery units based on derrick and base with comprising drill floor equipment in interior drill main body structure.As shown in Figure 2, the derrick delivery unit generally comprises overhead traveling crane, derrick, tourist bus, hook, water tap and drilling line; As shown in Figure 3, the base delivery unit generally comprises base, derrick man-like shelf, rig-floor tools, rotating disk and drive unit thereof, winch, driller's concubine and driller control house etc.Because also be mechanical whole dragging, therefore and integral body pull rig similar shortcoming arranged, but also the winch fast line of will dismantling, it is more loaded down with trivial details to seem in dismounting, but because of the appearance and size and the weight of its each delivery unit all significantly reduces, therefore is easier to realization.Much more comparatively the at present this whole mode of dragging sees.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned deficiency of the prior art, proposes a kind ofly to have hydraulic suspension, fluid-link steering, hydraulic-driven technology in the interior mechanism of walking certainly, to satisfy the whole movement of rig band drilling tool.What walking mechanism of the present utility model made the whole movement of rig band drilling tool has possibility and a reliability, it is reduced restriction of the volume and weight of delivery unit, but make only whole Transporting just under the situation that disconnects liquid, gas, power and water cable of drill main body unit.
In order to reach the foregoing invention purpose, rig of the present utility model is as follows from the technical scheme of the mechanism of walking:
A kind of mechanism of walking certainly of whole movement oil-well rig main computer unit, connect gooseneck, revolution support and driver element described comprising from the mechanism of walking, described connection gooseneck has two, removably be connected in the both sides, front and back of rig substructure respectively by bearing pin, connect gooseneck and be provided with the revolution support that can turn to, the revolution support base is provided with driver element, connect gooseneck top and be provided with power station and control system, this power station is connected by oil pipe with driver element, also is provided with steering mechanism on the connection gooseneck.
Described driver element comprises hanging oil cylinder, suspension, drive axle axle, hydraulic motor and reduction box, wheel rim and tire, the upper end of described suspension and hanging oil cylinder is connected revolution and supports, the lower end of suspension and hanging oil cylinder is fixed on the drive axle axle, described drive axle axle two ends are equipped with hydraulic motor and reduction box, hydraulic motor is connected with described wheel rim with reduction box, be fixed with described tire on the wheel rim, described hydraulic motor is connected with power station by oil pipe with reduction box.
Described steering mechanism is made up of first pivoted arm and second pivoted arm and driving oil cylinder, and described first pivoted arm supports top in revolution, and described second pivoted arm is in bottom that revolution is supported.
Described revolution support base can also be provided with driven unit.Described driven unit comprises driven bridge axle, hanging oil cylinder, suspension and tire, described suspension is connected revolution and supports and driven bridge axle with hanging oil cylinder, the two ends of described driven bridge axle are provided with wheel rim, be fixed with described tire on the wheel rim, the revolution that turns to the oil cylinder connection to be connected with driven unit in the steering mechanism is supported.
Based on technique scheme, of the present utility model have following technological merit from the mechanism of walking than prior art:
1. adopt of the present utility model from walking mechanism, but can make only whole Transporting just under the situation that disconnects liquid, gas, power and water cable of drill main body unit, this has saved the time of disassemblerassembler greatly, also saves the labour intensity and the man-hour of dismounting and transportation separately greatly.
2. this mechanism can guarantee the stationarity that drill main body equipment is walked on complex road surface, and each tyre load is all carried on a shoulder pole, and has therefore increased Transport Safety greatly.
3. this mechanism makes drill main body equipment action realize craspedodrome, diagonal smoothly, accurately and the multiple pattern that turns to such as walks crosswise, and the incomparable advantage of other mechanism is arranged when beating cluster well or regional well.
4. this mechanism adopts self power, has the automatic catch technology of total power coupling, makes huge, heavily loaded rig realize movement under the situation of no external impetus traction, and its development to drilling rig technique has revolutionary meaning equally.
5. the control mode of this mechanism is versatile and flexible, can be operating desk, driver's cabin, remote control panel, also can dispose wherein both, so that user flexibility is selected for use.
6. this mechanism is after connecting into integral body with rig substructure, utilize himself automatic walking function can move to the position and the delivery unit that connect drill main body accurately and connect into integral body, so whole connection procedure is very simple and convenient.
