The specific embodiment
At first referring to Fig. 3, Fig. 4, the utility model base is by lower guideway (1), (11), and П shape block (2), some connections support (3) and walking mechanism (4) are formed.In the well site is to install like this: elder generation is lower guideway (1), (11) fixedly, needs according to well head, two lower guideways (1), (11) are parallel and keep at a certain distance away and be placed on the platform, and adopt bolt or bearing pin connected mode that lower guideway (1), (11) are fixed as one with platform; Also lower guideway (1), (11) directly can be welded as a whole with platform.Lower guideway (1), (11) are welding steel I-beam structure or welding II shape steel beam structure (referring to Fig. 9, Figure 10).Lower guideway (1), (11) are respectively arranged with petroleum well servicing rig walking hole, Figure 11, Figure 11 A, Figure 12, Figure 12 A are respectively the arrangement architecture in two kinds of walking holes on the lower guideway, a kind of is single I-shaped setting, a kind of is double block form setting, the mobile point of application that provides that is set to petroleum well servicing rig in walking hole.
Referring to Fig. 3, Fig. 5, Fig. 6, П shape block (2) is two box trussed constructions, is made up of left block (21) and right block (22), can be set to open type trussed construction or enclosed container formula structure according to the petroleum well servicing rig needs.Open type trussed construction weight is lighter relatively, and it is little to hold the wind face, and the relative function of enclosed container formula structure is more, can serve as material room, toolhouse, pneumatics room etc.Present embodiment is the box trussed construction of open type.
Referring to Fig. 4, Fig. 7, it is (211), (212) as upper rall that left side block (21), right block (22) top respectively are provided with two longerons, (221), (222), and main guide rail (211), (221) realize that petroleum well servicing rig moves, inferior guide rail (212), (222) be as auxiliary carrying, about on two blocks main guide rail (211), (221) workover rig walking hole all is set.Primary and secondary two guide rail structures in top are all welding steel I-beam structure or welding II shape steel beam structure (referring to Fig. 9, Figure 10) mutually with the lower guideway structure; On two blocks on the main guide rail on the arrangement mode in walking hole and the lower guideway arrangement architecture in walking hole identical, a kind of is double block form setting, a kind of is single I-shaped setting (referring to Figure 11, Figure 12).
Referring to Fig. 3, Fig. 8 left side block (21), right block (22) is parallel and keep at a certain distance away and place the top of two lower guideways (1), (11) with lower guideway in vertical direction, two blocks (21), (22) bottom and lower guideway by slide block (52), place slide block (52) following clamp (53), bolt (51) to be connected, constitute the U-shaped position limiting structure by slide block (52), clamp (53), bolt (51), can effectively prevent the block derailing.Main frame sledge seat (50) and block top primary and secondary guide rail bindiny mechanism are identical with being connected of lower guideway with two blocks bottom, by slide block (52), place clamp (53), bolt (51) below the slide block (52) to constitute the connection of U-shaped position limiting structure.Article two, girder steel (6), (7) connect as one left block (21), right block (22) by bearing pin.
Adopt the П shape block of the box trussed construction of this open type, petroleum well servicing rig supporting capacity height, distance can be arranged very big between left block (21) and the right block (22).This structure makes that the well head space is open, adapts to than the multi-well location platform.Two pairs of guide rails on lower guideway (1), (11) and the П shape block (2) are in length and breadth to be arranged.
Middle connect support: several connect support (3), (8), (9), (10) by bearing pin respectively with fixing about junction plate on the junction plate on two blocks and two girder steels (6), (7) be connected, when whole base moves, play the transfer function of power, when normal brill, workover treatment, play the reinforcement stabilization.
The power that last lower guideway all utilizes walking mechanism (4) to provide can realize that petroleum well servicing rig moves in length and breadth.
Place the walking mechanism (4) on lower guideway (1), (11) to be connected with one of them block (21), place the walking mechanism of upper rail to be connected with petroleum well workover machine host sledge seat 50 (shown in the figure double dot dash line) by bearing pin by bearing pin.
Referring to Figure 13, Figure 14, walking mechanism is made up of junction plate (41), walking hydraulic cylinder (42), walking seat (43), ratchet (44), reversing handle (45).Junction plate (41) links together by bearing pin with the piston rod (46) of walking hydraulic cylinder (42), the piston rod of its other end (47) is connected with walking seat (43) by bearing pin, and the outer of walking seat (43) connects as one reversing handle and ratchet, ratchet, walking seat by pin framework.
By reversing handle (45) ratchet (44) is implemented commutation, ratchet (44) may be stuck in the guide rail walking hole, does two-way moving thereby promote or spur base by walking hydraulic cylinder (42), and the walking mechanism of this structure is simple in structure, and appearance and size is little, conveniently moving.Operating principle is as follows: b mouth oil-feed (rodless cavity loading), during the oil return of a mouth, walking hydraulic cylinder (42) piston rod stretches out, ratchet (44) is stuck in the guide rail walking hole, moves forward a setpoint distance thereby promote base, allows a mouth oil-feed (rod chamber loading) then, the oil return of b mouth, deadweight is regained walking fluid cylinder (42) by base, moves forward a setpoint distance thereby drive ratchet (44), promptly finishes an impulse stroke.According to same principle, allow b mouth oil-feed (rodless cavity loading) again, the oil return of a mouth makes base continue to move forward; When the reverse movable base of needs, by reversing handle (45) ratchet (44) is implemented commutation, promptly ratchet (44) is opposite with direction among the figure.A mouth oil-feed (rod chamber loading), during the oil return of b mouth, walking fluid cylinder (42) piston rod is regained, ratchet (44) is stuck in the guide rail walking hole, thereby the pulling base moves one backward and sets stroke, allows b mouth oil-feed (rodless cavity loading) then, the oil return of a mouth, deadweight is stretched out walking fluid cylinder (42) piston rod by base, thereby drives walking seat (43) and the mobile backward setting stroke of ratchet (44).According to same principle, allow a mouth oil-feed (rod chamber loadings) again, the oil return of b mouth, it is mobile backward that base is continued.
In sum, the utility model has quick for installation, safety owing to adopt technique scheme; The reliability height, supporting capacity is big, convenient transportation; It is many to adapt to well location, and the well head space is open; Be applicable to land and ocean cluster well operation.
