The specific embodiment
As shown in Figure 1 and Figure 2, jumbolter stride mechanism is made up of the hydraulic system of three hydraulic cylinder assemblies, two armature assemblies, after-poppet assembly and rig itself, two preceding hydraulic cylinder assemblies 3 and 4 are fastened on the rig forebay 1 by two armature assemblies, 6 usefulness bolts 8 respectively, back hydraulic cylinder assembly 5 is fastened on the rig lower bearing bracket 2 by after-poppet assembly 7 usefulness bolts 8, two preceding hydraulic cylinder assemblies 3 and 4 link with the sleeve of two armature assemblies 6 by armature assembly respectively, and back hydraulic cylinder assembly 5 and after-poppet assembly 7 link by the sleeve of after-poppet assembly.
Hydraulic system principle figure shown in Figure 3 is in whole rig controlled hydraulic system, distributes a circuit's principle figure of control stride mechanism.The hydraulic system that jumbolter stride mechanism can be achieved and the hydraulic system of jumbolter itself are one, fuel feeding provides by a fuel tank 12, the control of its each several part is all carried out independent allocation and control to the action of various piece respectively by the tetrad multi-way control valve 14 that is installed in the hydraulic system.Duplex gear pump 11 can rationally be regulated the pump amount according to the needs of drilling process, reduces power loss, reduces the oil temperature, prolongs the life-span of Hydraulic Elements.By the reading of pointer on the pressure meter 9, can reflect the system pressure of hydraulic system at that time.Tetrad multi-way control valve 14 be by four can individual control loop control valve be formed in parallel, promptly stride mechanism controls valve and telephone-moving oil cylinder control valve are realized the control loop of three support oil cylinders and the control loop of telephone-moving oil cylinder respectively.
Distributing valve 10 is the conversion elements for the large and small pumpage of controlling duplex gear pump 11, when system needs big flow and high pressure, can make large and small pump interflow by distributing valve 10, thereby make the flow of system and pressure improve.Duplex gear pump 11 is in low discharge work, and the flow of its big pump directly flows back to fuel tank 12, when the change lever of rotating distributing valve 10 can realize large and small pump interflow, gives system works simultaneously.The effect of overflow valve 13 is the pressure limits that are no more than permission for the pressure that guarantees system; and a kind of control element that hydraulic system is protected; when system pressure surpasses the force value of overflow valve 13 settings; overflow valve 13 beginning pressure releases; part hydraulic oil flows back to fuel tank by overfall, plays the effect of protection equipment hydraulic system.Fuel tank 12 mainly be used for the required hydraulic oil of stores hydraulic pressure system and to system's hydraulic oil cool off container.
Rig is the realization of shift function voluntarily in the drilling operation process, is to finish by the alternating movement that moves car oil cylinder 15 of rising and falling and being installed on the lower bearing bracket 2 of handling the rig support oil cylinder.At first, handle the telephone-moving oil cylinder control valve on the tetrad multi-way control valve, make 1 reach of rig upper spider, open the stride mechanism controls valve oil road on the tetrad multi-way control valve then, make three oil cylinder work and stretch out supporting leg, make whole frame built on stilts, handle the telephone-moving oil cylinder control valve on the tetrad multi-way control valve then, make 2 reaches of rig lower bearing bracket, at last, the stride mechanism controls valve of handling on the tetrad multi-way control valve makes three oil cylinder supporting legs regain original positions, such course of work, just realized rig from line displacement.Continue to realize the reach of rig, repeat the above-mentioned control course of work and get final product.
As shown in Figure 3, the stride connected mode and the operating principle of organization cylinder voluntarily is: the mode that adopts the synchronization loop of series connection cylinder, with three cylinders series connection, make the cavity of resorption hydraulic fluid port of oil cylinder I connect the epicoele hydraulic fluid port of oil cylinder II, the cavity of resorption hydraulic fluid port of oil cylinder II connects the epicoele hydraulic fluid port of oil cylinder III.
This has just guaranteed that the following cavity area of oil cylinder I equates with the last cavity area of oil cylinder II, the following cavity area of oil cylinder II equates with the last cavity area of oil cylinder III, under the situation of fuel feeding certain (fuel delivery that is the unit interval is certain), the effective area of oil cylinder equates, then its displacement equates, has so just realized the displacement synchronous interlock between three cylinders.
Rig with walking-type self-walking mechanism is compared with other rig in the industry, has following main feature:
1, a tractor serves several purposes both can satisfy engineering hole and creep into needs, can satisfy the need that the geological mapping hole drill advances again Want.
2, be furnished with walking-type self-walking mechanism, on-site construction operations is flexible, conveniently moving.
3, have the rational range of speeds, nearly 8 grades of numbers of speeds, scope from 64 rev/mins-1200 turn to/ Divide.
4, appearance and size is little, and adopts the oild chuck clamping to feed, can be in comparatively narrow and small place construction.
5, adopt the oil immersed type multi-disc friction clutch, have in conjunction with steadily, reliable operation, easy to operate, The characteristics such as the life-span is long, overload protection is good.
6, hydraulic system adopts duplex gear pump, can rationally regulate the pump amount according to the needs of drilling process, subtracts Few power loss reduces the oil temperature, prolongs the life-span of Hydraulic Elements.
7, rigidity of frame is good, and center of gravity is low, and is in light weight, good stability when creeping into.
8, be furnished with corresponding instrument, be beneficial to and grasp operating mode in the hole at any time, operating grip is less, and is rationally distributed, flexible and convenient operation.
