Description

Special multifunctional wrench for oil field well head

Technical Field

The utility model belongs to the supporting instrument of oil field well head device, concretely relates to special multi-functional spanner of oil field well head.

Background

The fastening and dismounting of wellhead screws and plugs is a routine work in the oil field. Because screws and plugs of different specifications need to be used for corresponding tools in work, the problems of multiple tools, low tool replacement efficiency and the like exist. Many people have studied wellhead tools, and the problems are expected to be solved, but the existing professional tools are single in function, inconvenient to carry and poor in practicability. At present, F-shaped wrenches, single socket wrenches and other tools are mostly used in the oilfield first line. Therefore, it is necessary to develop a multifunctional wellhead tool to improve the working efficiency and reduce the number of tools to be carried.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a special multifunctional wrench of oil field well head for it is single to solve current well head instrument usage, carries inconvenient problem.

A special multifunctional wrench for an oil field wellhead comprises: the wrench comprises a handle, a small socket wrench, a medium socket wrench and a large socket wrench, wherein the small socket wrench and the medium socket wrench are arranged at two ends of the handle; the small-size socket wrench, the medium-size socket wrench and the large-size socket wrench respectively comprise two sizes of sockets.

Furthermore, the number of the first through holes and the number of the second through holes are three respectively; the diameter of the first through hole is 15mm, and the diameter of the second through hole is 12 mm.

Furthermore, the F-shaped wrench fitting is connected with the first through hole and the second through hole through threads.

The utility model discloses the fastening of the well head screw of six specifications and end cap can be carried out and the auxiliary switch who dismantles and carry out multiple type valve to the instrument of the line work that significantly reduces carries quantity, reduces the number of times of change instrument, thereby promotes work efficiency.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

The present invention will be further explained with reference to the accompanying drawings:

as shown in figures 1-6, a special multifunctional wrench for oil field well head, including the handle, set up the small size box spanner 1 at handle both ends, medium size box spanner 3 and set up the large size box spanner 2 at the handle center, set up on the handle and lie in the first through-hole 4 between small size box spanner 1 and large size box spanner 2, set up on the handle and lie in the second through-hole 5 between medium size box spanner 3 and large size box spanner 2, with first through-hole 4, the F type spanner accessory 7 that second through-hole 5 is connected.

Small-size box spanner 1, medium-size box spanner 3 and large-size box spanner 2 each contain two kinds of size box spanner, can be used to not unidimensional well head screw and end cap dismantlement. The diameter of the circumscribed circle of the small-size socket wrench 1 is 32mm and 36mm, the diameter of the circumscribed circle of the large-size socket wrench 2 is 56mm and 61mm, and the diameter of the circumscribed circle of the medium-size socket wrench 3 is 41mm and 46 mm.

The first through hole 4 and the second through hole 5 are respectively three, threads are arranged in each through hole, and six F wrench sizes can be formed after the through holes are assembled with the F-shaped wrench fitting 7. The diameter of the first through hole 4 is 15mm, and the diameter of the second through hole 5 is 12 mm.

As shown in fig. 5a to 5b, the F-shaped wrench fitting 7 has a screw thread at one end and is connected to the first through hole 4 and the second through hole 5 through the screw thread.

As shown in fig. 7, during the in-service use, to not unidimensional well head screw and end cap, operating personnel only need select the utility model discloses the box spanner who corresponds the size carries out nested loading and unloading. And aiming at the fastening of valves with different sizes, selecting an F-shaped wrench fitting 7 with a proper size, connecting the fitting with the corresponding first through hole 4 or second through hole 5, and assembling to form six F-shaped wrenches with different models. The utility model discloses the instrument that will present oil field operation commonly used has carried out the rational combination, and the function is various, easy operation, and convenient to carry is with low costs, does benefit to the popularization.

Details not described in this specification are within the skill of the art that are well known to those skilled in the art.
