Description
Technical field
The present invention relates to a kind of New well drilling hoisting system, belong to petroleum gas drilling field of mechanical technique.
Background technology
In petroleum drilling and mining, hoisting system major function is drilling, setting of casing, control the pressure of the drill and drill bit creeps into, it is made up of winch, overhead traveling crane and derrick, drilling process needs having cooperated of distinct device creep into, but energy consumption, maintenance are challenged by numerous equipment, the situation that current oil price faced by especially is too low, in the urgent need to novel erecting equipment is studied and is discussed, to meet the needs of the outer petroleum industry situation of Present Domestic.
Summary of the invention
The invention aims to the deficiency overcoming prior art to exist, it is provided that a kind of New well drilling hoisting system, become the hoisting system of rectilinear motion mode with worm drive, reduce the complexity of hoisting system so that it is structure tends to simplifying, and is substantially reduced drilling cost.
The present invention solves that proposed problem be the technical scheme is that
One New well drilling hoisting system of the present invention, including motor, reductor, shaft coupling, angular contact bearing, slide rail, frame, lift bench, guiding assemblage, hook, base, upside lead, middle lead, downside lead, screw rod. Described motor and speed reducer is positioned at frame top, adopts vertical installation, and two output shafts of reductor are coupled by shaft coupling and two screw rods, and two screw rods are oppositely oriented; Screw rod is all intersected by double thread groove and forms, contrary about the rotation direction of thread groove; Hook can be installed below described lift bench, it is also possible to top drive system is installed; Lift bench and guiding assemblage link together, guiding assemblage drive lift bench to pump; Lead includes upside lead, middle lead, downside lead; Lead in the guiding assemblage of two screw rods is symmetrically installed, the side force produced when rising with balanced spiral.
Described screw rod can be two, it is also possible to is four, and the worm drive of screw rod become during work the rectilinear motion of lift bench so that it is the motion on screw rod is more steady.
Advantages of the present invention and beneficial effect:
1, the drilling well hoisting system of the present invention may replace the winch in tradition hoisting system, overhead traveling crane and derrick;Simple in construction, effectively reduces drilling cost, and convenient for maintaining maintains. 2, adopt screw flight groove twist belt drive structure, overcome acceleration and the excessive problem of inertial load, it is ensured that motor Unidirectional makes smooth working. 3, whole hoisting system floor space is little, and complete machine adopts truss structure, and section bar is rectangle steel, and overall mass is lighter, and is readily transported. 4, can according to different drilling well situations, by increasing the length of screw rod, to meet the drilling well under different condition.
Accompanying drawing explanation

In figure, 1. motor; 2. reductor; 3. shaft coupling; 4. angular contact bearing; 5. slide rail; 6. frame; 7. lift bench; 8. guiding assemblage; 9. hook; 10. base; 11. upside lead; 12. middle lead; 13. downside lead; 14. screw rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical scheme is described specifically:
As shown in Figure 1, one New well drilling hoisting system of the present invention, including motor 1, reductor 2, shaft coupling 3, angular contact bearing 4, slide rail 5, frame 6, lift bench 7, guiding assemblage 8, hook 9, base 10, upside lead 11, middle lead 12, downside lead 13, screw rod 14. Described motor 1 and reductor 2 are positioned at frame top, adopt vertical installation, and 2 two output shafts of reductor are coupled with two screw rods 14 by shaft coupling 3, and two screw rods 14 are oppositely oriented; Screw rod 14 is all intersected by double thread groove and forms, contrary about the rotation direction of thread groove; Below described lift bench 7, hook can be installed, it is also possible to top drive system is installed; Lift bench 7 and guiding assemblage 8 link together, guiding assemblage 8 drive lift bench 7 to pump; Lead includes upside lead 11, middle lead 12, downside lead 13; Lead in the guiding assemblage 8 of two screw rods 14 is symmetrically installed, the side force produced when rising with balanced spiral.
Screw rod 14 can be two, it is also possible to is four, and the worm drive of screw rod 14 become during work the rectilinear motion of lift bench 7 so that it is the motion on screw rod 14 is more steady.
When hoisting system carries out normal operation, reductor 2 is driven to operate by motor 1, two output shafts of reductor 2 drive the rotation of two screw rods 14 by shaft coupling 3, two screw rods 14 are oppositely oriented, owing to screw rod 14 adopts the oppositely oriented combined crosswise of double thread groove, when the guiding assemblage 8 in lift bench 7 moves to the crossing of double spiral groove, upside lead 11 is firstly moved to helicla flute crossing, now only middle lead 12 and continues to roll along helicla flute at lower groove face bearing load with downside lead 13, when upside lead 11 is by behind spiral crossing, downside lead 13 and middle lead 12 alternately carrying respectively through residue lead, pass sequentially through double spiral groove crossing, realizing guiding assemblage 8 drives lift bench 7 along the steady transmission of screw rod 14.
After guiding assemblage 8 is by last double spiral groove crossing on screw rod 14 top, guiding assemblage 8 will move along a non-isometric helicla flute, when screw rod 14 spiral fluted tip position, upside lead 11 contacts with spiral fluted upper groove surface, owing to being subject to the active force of upper groove surface, thus upside lead 11 completes commutation, each lead is alternately subject to upper groove surface active force, is sequentially completed commutation; Break-in by guiding assemblage 8 top and bottom, it is achieved the single direction rotation of screw rod 14 becomes guiding assemblage 8 and drives the linear reciprocating motion of lift bench 7, lift bench 7 rectilinear motion up and down reciprocatingly to complete drilling, setting of casing, controls the pressure of the drill and drill bit creeps into.
