Description
Technical field
It the utility model is related to oil exploration monitoring technical field, more particularly to a kind of preventer lifting mobile device.
Background technology
Preventer lift mobile device exclusively for meet petroleum drilling drilling team installation, dismounting preventer and design.Using
All-hydraulic control, it is supporting available for large and medium-sized drilling equipment.Its major function：Mobile single preventer or the blowout prevention combined
Device group is installed.The lifting machine hung on by the control of hydraulic operation platform on the guide rail of drilling floor surface bottom two, realizes synchronization onwards
Rise, decentralization, reach, it is rear move, and respectively raising, decentralization and the reach of limited separating distance (maximum separation distance≤1m), after
Move, greatly facilitate the installation and removal of preventer, and there is the characteristics of explosion-proof, simple to operate, reliable, safe.
The mobile device of domestic preventer lifting at present, as executing agency, passes through oil cylinder head and oil using hydraulic jack
Wire rope rope between the assembly pulley that cylinder is fixed on body realizes the hoisting function of preventer.Increased simultaneously using two strand systems
Add raising stroke, reduce oil cylinder stroke.Some producers are then in order to obtain bigger raising stroke, using double forms for stretching oil cylinder.
Also can only achieve that raising stroke is oil cylinder stroke using two strand systems twice.Single oil cylinder is although reduced using double oil cylinders of stretching
Stroke, but add the length and weight of whole device.It has impact on the manipulation space under limited drilling floor surface.
Utility model content
The purpose of this utility model is to provide a kind of preventer lifting mobile device, solves oil cylinder row of the prior art
Cheng Gao, the technical problem for manipulating space that have impact under limited drilling floor surface.
A kind of preventer lifts mobile device, including oil cylinder, assembly pulley and lifting rope, and first is disposed with the oil cylinder
Guide roller frame, second pulley framework and the 3rd guide roller frame, the 3rd guide roller frame is located at the piston rod end of oil cylinder, described
Assembly pulley includes movable pulley, leading block and fixed pulley, and the leading block installs first pulley lower portion, the fixed pulley
Installed in second pulley lower portion, the movable pulley is arranged on inside the 3rd guide roller frame, and described lifting rope one end is fixed on the
Bypass on three guide roller frames and successively vertical lower section after fixed pulley, movable pulley and leading block.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement：
Further, the fixed pulley tilts installation, and the fixed pulley top is located at same level with the 3rd guide roller frame
Face, the fixed pulley bottom are located at same level with movable pulley.
Further, angle is equal between the two sections of lifting ropes and the axis of the oil cylinder on the fixed pulley.
Further, at least two hangers are set above the oil cylinder.
The beneficial effects of the utility model：
The utility model is that a kind of preventer lifts mobile device, by the way that fag end is fixed on oil cylinder head, realizes three sections
Rope system, the two sections of lifting ropes tilted using fixed pulley in installation and fixed pulley are equal with the angle between oil cylinder axis, so ensure
Cylinder piston rod is only stressed, not bending moment power；The utility model is simple in construction, and can realize that oil cylinder stroke does not increase, but
Add raising stroke.
Brief description of the drawings
, below will be right in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
The required accompanying drawing used is briefly described in embodiment or description of the prior art, it should be apparent that, describe below
In accompanying drawing be some embodiments of the present utility model, for those of ordinary skill in the art, do not paying creativeness
On the premise of work, other accompanying drawings can also be obtained according to these accompanying drawings.

Embodiment
The technical solution of the utility model is clearly and completely described below in conjunction with accompanying drawing, it is clear that described
Embodiment is the utility model part of the embodiment, rather than whole embodiments.Based on the embodiment in the utility model, sheet
The every other embodiment that field those of ordinary skill is obtained under the premise of creative work is not made, belongs to this practicality
Novel protected scope.
As shown in figure 1, a kind of preventer lifting mobile device provided by the utility model, including oil cylinder 1, assembly pulley 2
With lifting rope 3, first pulley framework 4, the guide roller frame 6 of second pulley framework 5 and the 3rd are disposed with the oil cylinder 1, it is described
3rd guide roller frame 6 is located at the piston rod end of oil cylinder 1, and the assembly pulley 2 includes movable pulley 7, leading block 8 and fixed pulley 9,
The leading block 8 is installed inside first pulley framework 4, and the fixed pulley 9 is arranged on inside second pulley framework 5, described dynamic
Pulley 7 is arranged on inside the 3rd guide roller frame 6, and described one end of lifting rope 3 is fixed on the 3rd guide roller frame 6 and successively around fixed sliding
Vertical lower section after wheel 9, movable pulley 7 and leading block 8；Using the cooperation of lifting rope 3 and assembly pulley 2, so same oil cylinder stroke,
The raising stroke of fag end but adds.
Wherein, the fixed pulley 9 tilts installation, and the top of fixed pulley 9 is located at same level with the 3rd guide roller frame 6
Face, the bottom of fixed pulley 9 are located at same level with movable pulley 7, and can so ensure the piston rod of oil cylinder can only be pressed
