When standby, passed through with small winch wire rope out of rig floor middle body turret apertures, around rig floor bottom outer, blocking needs assembling
Equipment after lift.Need manually to have been hauled with rope because the equipment of lifting is on the tapered plane of rig floor bottom outer, during lifting
Hang, easily cause extension, the card of rope, or even break steel wire rope and cause the accidents such as lifting object landing.Not only easily cause operating personnel
Personal injury, while to equipment cause damage.
The content of the invention
The utility model is filled for the operation present situation of workover treatment rig floor handling facilities there is provided a kind of lifting of operation wellhead
Put, during workover treatment, used when the well head such as handling blowout preventer, production tree and well workover facility, reach the mesh of safety in production
, operating efficiency is improved, the labor intensity of operating personnel is reduced, production facility is protected.
What the utility model was realized in：A kind of operation wellhead hanging apparatus includes hydraulic wireline winch, and guide rail passes through guide rail
Suspension rod is fixed on the lower surface of rig floor, and operational hydraulic cylinder is fixed on the side of rig floor, the piston rod of operational hydraulic cylinder by fluid cylinder support
Welded with hydraulic wireline winch, hydraulic wireline winch is arranged in guide rail；Two oil-outs of hydraulicdirectional control valve are distinguished by hydraulic line
It is connected with the hydraulic oil port of hydraulic wireline winch and operational hydraulic cylinder, the oil inlet of hydraulicdirectional control valve is connected by hydraulic line and hydraulic power source
Connect.
The beneficial effects of the utility model are：The utility model be it is a kind of sling from rig floor bottom moved in parallel after equipment to
The device of well head top position, it is convenient to load and unload the wellhead components such as blowout preventer, production tree and well workover facility, it is to avoid artificial use
Rope hauls the defect of lifting, the personal safety of staff has been effectively ensured, production equipment is protected, it is to avoid safe thing
Therefore.The problem of solving the handling difficulty that current wellhead equipment and well workover facility are present, eliminates shaft mouth operation personal height peace
Dress operation, it is ensured that production safety, it is to avoid damage of the production equipment in cargo handling process, with good using effect and should
With value.
Brief description of the drawings
Fig. 1 is operation principle schematic diagram of the present utility model.
Embodiment
The present invention is described in detail below in conjunction with accompanying drawing, not limited the scope of the invention, all designs using the present invention are thought
The improvement that rood goes out belongs to the protection category of the present invention.
Referring to Fig. 1, a kind of operation wellhead hanging apparatus includes hydraulic wireline winch 6, and guide rail 7 is fixed on brill by guide rail suspension rod 8
The lower surface of platform 1, operational hydraulic cylinder 3 is fixed on the side of rig floor 1 by fluid cylinder support 2, and piston rod and the hydraulic pressure of operational hydraulic cylinder 3 are twisted
Car 6 is welded, and hydraulic wireline winch 6 is arranged in guide rail 7；Two oil-outs of hydraulicdirectional control valve 5 by hydraulic line 4 respectively with liquid
The hydraulic oil port connection of winch 6 and operational hydraulic cylinder 3 is pressed, the oil inlet of hydraulicdirectional control valve 5 is connected by hydraulic line 4 and hydraulic power source
Connect.The lower section of rig floor 1 is provided with rig floor pillar 9.
The base lower end of the hydraulic wireline winch 6 is equipped with roller, and the wheel face of the roller coordinates with the guide groove of guide rail 7, in liquid
Press the base lower end of winch 6 that roller is installed, make its slip smooth.
The front end of the piston rod of operational hydraulic cylinder 3 is more than with the tube chamber welds with base of hydraulic wireline winch 6, the collapsing length of piston rod
2m, such as 2.5m, 3m, are determined according to the size of rig floor 1.
The guide rail 7 is more than the radius of rig floor 1 provided with two, its length, and the front end of guide rail 7 is fixed by guide rail suspension rod 8
Lower section in the outer rim lower end of rig floor 1, the rear end fixed position of guide rail 7 is corresponding with the outer peripheral outside of well head.
The length of the guide rail suspension rod 8 is more than the height of hydraulic wireline winch 6, makes the roller and its rope above of hydraulic wireline winch 6
Rope retractable is operated freely.
The hydraulic power source includes workover rig hydraulic fluid tank and the hydraulic fluid tank of dedicated hydraulic equipment.
By the oil inlet of hydraulicdirectional control valve 5 of the present utility model and workover rig hydraulic fluid tank or dedicated hydraulic equipment hydraulic fluid tank
Power taking mouthful, i.e. oil-out are connected, and when operation wellhead needs to install the equipment such as blowout preventer, fracture well head, press hydraulicdirectional control valve 5,
Operation element fluid cylinder 3, moves to hydraulic wireline winch 6 marginal position of rig floor 1.Then hydraulicdirectional control valve 5 is pressed, hydraulic wireline winch is operated
