Description
Technical field
The utility model relates to a kind of aid that oil drilling production scene, oil field uses, and is a kind of surface pipe screw thread helmet extracting tool.
Background technology
In recent years, along with the fast development of shallow sea (such as: Bohai Sea Gulf) oil gas field probing exploitation, the production well group of current offshore drilling platform construction is all generally more than 20 mouthfuls of wells, bit speed is fast, cycle of creeping into is short, because every mouthful of well is after first time spuds in, all want the surface pipe (Bohai Bay oil-gas field) that lower going-into-well intraocular 450 meters to 700 meters is dark, before layer sleeve pipe, first the screw thread helmet of surface pipe rear and front end to be unloaded, but because the surface pipe of upper well can collide in transportation, result in the surface pipe screw thread helmet after well to be difficult to unload, in addition specific purpose tool is not had, manpower can only be leaned at the scene to use pipe wrench to unload surface pipe screw thread helmet, because pipe wrench is not the specific purpose tool being used for dismantling surface pipe screw thread helmet specially, also be rather difficult so operate, and labour intensity is large, speed is very slow, easily skid when biting surface pipe screw thread helmet with pipe wrench in addition, so the accident that hand touches pin often can be knocked.
Summary of the invention
The purpose of this utility model is to provide a kind of surface pipe screw thread helmet extracting tool, can be disassembled on surface pipe by surface pipe screw thread helmet easily and fast, safely.
Use the technical program can achieve the above object: surface pipe screw thread helmet extracting tool by: clamping head, connecting screw rod, locking nut, dismounting dop, intermediate connecting part, clamping screw die and caging bolt form.Described clamping head is provided with the screw die groove installing clamping screw die, clamping screw die is arranged in the screw die groove on clamping head; Described intermediate connecting part two ends are provided with screwed hole, and this screwed hole specification conforms to connecting screw rod external screw thread; Described locking nut is GB hex nut, and its specification conforms to connecting screw rod external screw thread; Described intermediate connecting part middle part arranged outside has dismounting dop, and use in order to connecting the instruments such as monkey wrench, inner side is provided with caging bolt, and caging bolt and intermediate connecting part are threaded connection.
The beneficial effects of the utility model: structure is simple, cheap, in use clamp effective, so in application process, safe and reliable, surface pipe screw thread helmet can be dismantled safely and fast, improve produced on-site efficiency, there is significant economic and social benefit.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing is the contour structures schematic diagram after the utility model assembling.
Detailed description of the invention
In conjunction with Figure of description, the utility model will be further described: surface pipe screw thread helmet extracting tool mainly comprises clamping head 1, connecting screw rod 2, locking nut 3, dismounting dop 4, intermediate connecting part 5, component names such as clamping screw die 6 and caging bolt 7 etc.Described intermediate connecting part 5 adopts 45
#steel are made, and the screwed hole screwed mutually with connecting screw rod 2 is provided with at its two ends, the connecting screw rod 2 on intermediate connecting part 5 two ends and clamping head 1, is connected by threaded engagement, after length adjustment is suitable, use locking nut 3 itself and intermediate connecting part 5 to be locked and be integrated; Described clamping head 1 and the as a whole parts of connecting screw rod 2, the working face place of clamping head 1 is provided with the mounting groove installing clamping screw die 6, by clamping the installation of screw die 6, the utility model can be made effectively to be clamped on surface pipe screw thread helmet, caging bolt 7 rightings of intermediate connecting part 5 now, supporting role, after regulating the A/F of monkey wrench, be clamped on by monkey wrench on dismounting dop 4, pulling monkey wrench handle can disassemble safely and fast by surface pipe screw thread helmet.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, the common technique personnel of this area are to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
