Description
Technical field
The utility model relates to a kind of workover rig, particularly one novel adjustable wellhead formula workover rig.
Background technology
Workover rig is mainly used in the salvaging of drilling tool, the completion of Oil/gas Well, and the operations such as oil well maintenance, in oil well industry extensive application.Workover rig operation is generally after shaping oil field or drilling technology, and pithead position is established, and due to interference such as surrounding obstacles, makes traditional vehicle-mounted workover rig be difficult to accurately aim at well head.The utility model provides a kind of novel adjustable wellhead formula workover rig, and the adjustable movement of derrick, conveniently realizes the centering of well head, and structure is simple, has stronger practical value.
Summary of the invention
The purpose of this utility model is exactly the deficiency existed for prior art, and provide a kind of novel adjustable wellhead formula workover rig, the adjustable movement of derrick, conveniently realizes the centering of well head, and structure is simple, has stronger practical value.
It is characterized in that: a kind of novel adjustable wellhead formula workover rig, primarily of frame, bearing, cylinder, crossbeam, axle bed, leading screw, base, clamp nut, feed rod, derrick and head sheave composition, described frame is provided with guide rail hole and lower discharge hole, described bearing is fixed in frame, described cylinder is arranged on bearing, above described bearing, crossbeam is installed, described four axle beds are fixed in frame, described leading screw is arranged on a pair axle bed, described leading screw is provided with handwheel, described feed rod is arranged on another on axle bed, base is fixed in frame through the guide rail hole of frame by described clamp nut, described base is provided with support, described base lower end is provided with unthreaded hole and screwed hole, described unthreaded hole coordinates with feed rod, described screwed hole coordinates with leading screw, described derrick installation is on support, described derrick top is provided with head sheave.
Loosen described clamp nut, regulate the handwheel of described leading screw, derrick can advance or retreat under the effect of leading screw and feed rod, realize the well head centering of workover tool, again tighten clamp nut after completing well head centering and fix base, derrick is fastened on the support of base, described cylinder relies on wire rope to walk around crown head sheave to hang workover tool, workover tool enters well head through the lower discharge hole of described frame, derrick can be loosened on the support of base after completing workover treatment, derrick is retreated on being poured on above cylinder crossbeam, save space.
Accompanying drawing explanation
Accompanying drawing 1 is well workover view of the present utility model.
Accompanying drawing 2 is that schematic diagram toppled over by derrick of the present utility model.
In upper figure: frame 1, guide rail hole 1.1, lower discharge hole 1.2, bearing 2, cylinder 3, crossbeam 4, axle bed 5, leading screw 6, handwheel 6.1, base 7, support 7.1, unthreaded hole 7.2, screwed hole 7.3, clamp nut 8, feed rod 9, derrick 10, head sheave 11.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model is primarily of frame 1, bearing 2, cylinder 3, crossbeam 4, axle bed 5, leading screw 6, base 7, clamp nut 8, feed rod 9, derrick 10 and head sheave 11 form, described frame 1 is provided with guide rail hole 1.1 and lower discharge hole 1.2, described bearing 2 is fixed in frame 1, described cylinder 3 is arranged on bearing 2, above described bearing 2, crossbeam 4 is installed, described four axle beds 5 are fixed in frame 1, described leading screw 6 is arranged on a pair axle bed 5, described leading screw 6 is provided with handwheel 6.1, described feed rod 9 is arranged on another on axle bed 5, base 7 is fixed in frame 1 through the guide rail hole 1.1 of frame 1 by described clamp nut 8, described base is provided with support 7.1, described base 7 lower end is provided with unthreaded hole 7.2 and screwed hole 7.3, described unthreaded hole 7.2 coordinates with feed rod 9, described screwed hole 7.3 coordinates with leading screw 6, described derrick 10 is arranged on support 7.1, described derrick 10 top is provided with head sheave 11.
Loosen described clamp nut 8, regulate the handwheel 6.1 of described leading screw 6, derrick 10 can advance or retreat under the effect of leading screw 6 and feed rod 9, realize the well head centering of workover tool, again tighten clamp nut 8 after completing well head centering and fix base 7, derrick 10 is fastened on the support 7.1 of base 7, described cylinder 3 relies on wire rope to walk around derrick 10 top head sheave 11 to hang workover tool, workover tool enters well head through the lower discharge hole 1.2 of described frame 1, derrick 10 can be loosened on the support 7.1 of base 7 after completing workover treatment, derrick 10 is retreated on being poured on above cylinder 3 crossbeam 4, save space.
The invention has the beneficial effects as follows: the adjustable movement of derrick, conveniently realizes the centering of well head, structure is simple, has stronger practical value.
