Description
Technical field
The utility model relates to a kind of long-range hydraulic selector well device of speedily carrying out rescue work for oil and gas wellhead, belongs to petroleum gas well head emergency technique field.
Background technology
Oil gas well well head leaks not only serious threat people's the life security of catching fire, and contaminated environment is serious, if deal with improperly, consequence is hardly imaginable, and key measure is to strive for robbing closing well port strobe (particularly 1# master control valve) in the very first time.The existing way in each oil field is to rely on the personnel of speedily carrying out rescue work to wear fire proximity suit to rush in the scene of a fire, with common pipe wrench closed-in well port strobe., valve core rod big owing to borehole pressure easily flies out and secondary may take place and dodge reasons such as quick-fried, and the personnel that speedily carry out rescue work are very big in the danger that well head faces.Simultaneously, the big pressure reduction of valve upstream and downstream has increased the moment of torsion of valve-off, even two people also are difficult to pull gate.
Summary of the invention
The purpose of this utility model is to provide a kind of long-range hydraulic selector well device of speedily carrying out rescue work for oil and gas wellhead, and it can catch fire that well head carries out rapidly to oil gas well accident, safety and rob the pass effectively.
Concrete technical scheme of the present utility model is as follows:
Hydraulic power station is connected and composed by fuel tank, hydraulic pump, overflow valve, switch valve and pressure regulator valve; Hydraulic power station connects the hydraulic gerotor motor by hydraulic line; Balancing pole is fixed on the work car by swivel pin and The Cloud Terrace; The hydraulic gerotor motor is fixed on the balancing pole, and its output connects the bevel gear group by power transmission shaft, and bevel gear group output connects tire.
The utility model can directly act on the mechanical torque that increases the gate of accident well head by long-range electronic control, realizes that the gate in the very first time is robbed the pass, and the personnel's that can keep the scene intact life security avoids environment by severe contamination.This device can be widely used in the switching operations of the large-scale ball valve manual executing agency in emergency circumstances of surging.
Description of drawings
Fig. 1 is for being used for the long-range hydraulic selector well schematic representation of apparatus that oil and gas wellhead is speedily carried out rescue work.
Fig. 2 is the connection diagram of hydraulic power station equipment.
The specific embodiment
With reference to Fig. 1 and 2 embodiment of the present utility model is further specified:
Embodiment:
The utility model is made up of hydraulic power station 1, hydraulic line 2, hydraulic gerotor motor 3, power transmission shaft 4, bevel gear group 5, tire 6, The Cloud Terrace 7, work car 8, swivel pin 9 and balancing pole 10:
Hydraulic power station 1 is connected and composed by fuel tank 11, hydraulic pump 12, overflow valve 13, switch valve 14 and pressure regulator valve 15.Hydraulic power station 1 connects hydraulic gerotor motor 3 by hydraulic line 2.Balancing pole 10 is fixed on the work car 8 by swivel pin 9 and The Cloud Terrace 7.Hydraulic gerotor motor 3 is fixed on the balancing pole 10, and its output connects bevel gear group 5 by power transmission shaft 4, and bevel gear group 5 outputs connect tire 6.
According to actual needs, hydraulic power station 1 can be regulated moment of torsion by pressure regulator valve 15, if moment of torsion exceeds design, is then protected by overflow valve 13 releasing pressure automaticallies.Switch valve 14 adopts spring 3-position 4-way valve arrangement, by the direct far-end control of the personnel of speedily carrying out rescue work.Hydraulic gerotor motor 3 is passed to bevel gear group 5 and tire 6 with outputting torsion, to increase steering torque, realizes that working distal tip turns to, the risk that also can avoid spool to fly out and cause simultaneously.For fear of temperatures involved, hydraulic line 2 adopts high temperature resistant model, and hydraulic gerotor motor 3 adopts inflammable material parcel.Balancing pole 10 is used to the working end counterweight, and it can horizontally rotate and swing up and down, and tire 6 is aimed at gate handwheel 16 like a cork.Balancing pole 10 length 2m can decide voluntarily according to on-the-spot needs, carry and on-the-spot assembling so that speedily carry out rescue work.Tire 6 is connected bevel gear group 5 by inside and outside four directions with pin, if the well head gate is provided with handwheel, then adopt the tire working end, if there is not handwheel (handwheel is lost or damaged), then adopts six square socket working ends.
The course of work of the present utility model is as follows:
When oil and gas wellhead take place to leak and catches fire, the personnel that speedily carry out rescue work namely carried each parts of device of originally speedily carrying out rescue work and enter scene of the accident weather and assemble fast.The lineup is connected in bevel gear group 5 outputs with pin with tire 6, and balancing pole 10, hydraulic gerotor motor 3 and bevel gear group 5 are connected, and again 10 of balancing poles is swung balancing pole 10 then on The Cloud Terrace 7, tire 6 is docked on the gate handwheel 16 of well head.Simultaneously, the lineup pushes the scene with hydraulic power station 1 in addition, is connected hydraulic power station 1 and hydraulic motor 3 with hydraulic line 2 with snap joint.The operator stands on the operating desk at a distance, by observing last group of personnel's the signal operating switch valve 14 of waving, starts hydraulic power station 1.Power is delivered to bevel gear group 5 and tire 6 through hydraulic gerotor motor 3 and power transmission shaft 4, and tire 6 pins gate handwheels 16, and drives gate handwheel 16 with the reinforcement moment of torsion of its acquisition and rotate, rapidly, safety and effectively well head main control valve door out of control being closed.
At the beginning of 2011, in natural gas well site, Su Lige gas field, carry out the natural gas well and leak the emergency repair combat exercise of catching fire, christmas tree model KQ-65/70, comburant are natural gas and condensate mixture in the well.After the device assembles, the safety zone easily to upper lock gate, is removed then in this switch well device working end.The rear personnel that speedily carry out rescue work start the device of speedily carrying out rescue work, and only more than 20 second time spent, have just closed well head 1# valve rapidly, and big fire is extinguished immediately, the success of speedily carrying out rescue work.
