Description
Technical field:
The present invention relates to a kind of hydraulic pressure does not have the winch workover rig, belongs to the oil extraction machinery and equipment design field.
Background technology:
In recent years, hydraulic workover unit uses more and more widely in the oil field, the trend that replaces the mechanical transmission-type workover rig is arranged, this be since hydraulic workover unit have in light weight, volume is little, compact conformation, the power that feeds are big, stable drive, easy operation and realize infinitely variable speeds easily and series of advantages such as control automatically, and makes equipment can finish the several work function by the appropriate design to hydraulic system.
From the erecting equipment of hydraulic workover unit equipment, the hydraulic petroleum workover rig has two kinds of fundamental types at present, and a kind of is common hydraulic workover unit, and a kind of is that hydraulic pressure does not have the winch workover rig.
The hydraulic workover unit that generally use in present domestic each oil field is common hydraulic workover unit, the same with the mechanical transmission-type workover rig, the erecting equipment of common hydraulic workover unit mainly by winch, overhead traveling crane, derrick, hook block or power swivel, wire rope and other well head make a trip the operation machine tool form.Winch drives by prime mover group, and prime mover group is 2--4 platform engine normally, is used for promoting, transferring drilling rod etc.The hydraulic drive of common hydraulic workover unit is incomplete, is in half hydraulic pressure, half mechanically operated level.
And hydraulic pressure does not have the winch workover rig, its erecting equipment by hydraulic cylinder, assembly pulley, derrick, hook block or power swivel, wire rope and other well head make a trip the operation machine tool form.It replaces traditional winch, transmission mechanism, overhead traveling crane etc. by simple mechanisms such as hydraulic cylinder and pulley, wire rope are installed, thereby makes that the Hoisting System scheme is simple, compact conformation, and volume is little, light weight, cost is low.All parts that hydraulic pressure does not have the winch workover rig all adopt same hydraulic power supply to drive, and are complete hydraulicdriven workover rigs.
The employed hydraulic workover unit of China mostly is common hydraulic workover unit greatly at present, and its volume is big, and quality is heavy, complex structure, maintenance cost height, and fault rate is higher in workover treatment, far can not adapt to requirements of actual production.
Summary of the invention:
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of hydraulic pressure not have the winch workover rig, it is simple to make it have a system schema, compact conformation, volume is little, light weight, cost is low, advantages such as technical-economic index advanced person.
The present invention realizes above-mentioned purpose by following technical solution.
Do not have in the structure of winch workover rig at a kind of hydraulic pressure, be provided with and promote steel cable, long stroke hydraulic cylinder, guide rail, fluid cylinder leading truck, traveling sheave, piston rod, equalizer assembly, dead line anchor, fluid cylinder base; The fluid cylinder leading truck adopts the portal-framed structure form; In the fluid cylinder leading truck, be symmetrically installed with two fluid cylinder bases and long stroke hydraulic cylinder, the long stroke hydraulic cylinder is installed on the fluid cylinder base; In the fluid cylinder leading truck guide rail is housed, piston rod can move up and down along the guide rail in the fluid cylinder leading truck; Traveling sheave is installed in the top of piston rod; Outer lower portion at the fluid cylinder leading truck is provided with dead line anchor, and an end that promotes steel cable is fastened on the dead line anchor, and the other end is walked around traveling sheave and is fixed on the equalizer assembly.
The present invention has following beneficial effect compared with prior art:
1, adopted multiplication journey hydraulic jack pulley system, the movement velocity of hoisting mechanism, active force and output torque can be carried out step-less adjustment along with the variation of workover process, and the adjustable range broad; The hoisting mechanism commutation rapidly, and is accurate, and convenient, nothing is impacted; The movement velocity of equalizer assembly is two times of piston rod movement speed, has improved workover treatment efficient.
2, realized full hydraulic drive fully, no work spark makes workover treatment safer.
3, replace traditional winch, transmission mechanism, overhead traveling crane etc. by simple mechanisms such as mounting guide rail, hydraulic cylinder, pulley, wire rope in the fluid cylinder leading truck, make that the Hoisting System scheme is simple, compact conformation, volume is little, light weight, cost is low, the technical-economic index advanced person.
Description of drawings:
Fig. 1 does not have the general structure schematic diagram of winch workover rig for a kind of hydraulic pressure.
In the drawings: 1. promote steel cable, 2. long stroke hydraulic cylinder, 3. guide rail, 4. fluid cylinder leading truck, 5. traveling sheave, 6. piston rod, 7. equalizer assembly, 8. dead line anchor, 9. fluid cylinder base.
The specific embodiment:
A kind of hydraulic pressure of the present invention does not have the winch workover rig and is made up of lifting steel cable 1, long stroke hydraulic cylinder 2, guide rail 3, fluid cylinder leading truck 4, traveling sheave 5, piston rod 6, equalizer assembly 7, dead line anchor 8, fluid cylinder base 9; Fluid cylinder leading truck 4 adopts the portal-framed structure form; In fluid cylinder leading truck 4, be symmetrically installed with two fluid cylinder bases 9 and long stroke hydraulic cylinder 2, long stroke hydraulic cylinder 2 is installed on the fluid cylinder base 9; Guide rail 3 is housed in fluid cylinder leading truck 4, and piston rod 6 can move up and down along the guide rail 3 in the fluid cylinder leading truck 4, makes piston rod 6, traveling sheave 5 and equalizer assembly 7 not vibrate when moving up and down; Traveling sheave 5 is installed in the top of piston rod 6, and traveling sheave 5 is connected with the top of piston rod 6 by the screw thread of its bottom; Outer lower portion at fluid cylinder leading truck 4, be provided with dead line anchor 8, an end that promotes steel cable 1 is fastened on the dead line anchor 8, the other end is walked around traveling sheave 5 and is fixed on the equalizer assembly 7, can be so that the movement velocity of equalizer assembly 7 be twices of piston rod 6 movement velocitys of hydraulic cylinder, mention and transfer drilling rod thereby drive equalizer assembly 7.
During work, when protruding upward along with the piston rod 6 of hydraulic cylinder, the guide rails 3 that traveling sheave 5 is installed in the fluid cylinder leading truck 4 also move upward, and at this moment equalizer assembly 7 just can promote drilling rod.When the piston rod 6 of hydraulic cylinder was withdrawn downwards, traveling sheave 5 also moved downward along guide rail 3, and equalizer assembly 7 just can be transferred drilling rod at this moment.
