Abstract
A special combination tool for a well head in an oil field is applicable to maintenance of the well head in the oil field, and is characterized in that a cylindrical stress application rod is perpendicularly welded on the outer wall of one end of a wrench main body, a main body joint is welded on the surface of other end of the wrench main body, and the main body joint is cylindrical and has a regular hexagonal center hole; and a wrench inserter comprises a baffle, hexagonal prism bodies, an outside-hexagonal wrench head and a square open end wrench head. The hexagonal prism bodies are respectively arranged on the two side surfaces of the baffle, the outside-hexagonal wrench head is arranged at the other end of one hexagonal prism body and is a regular hexagonal hole; and the square open end wrench head is arranged at the other end of the other hexagonal prism body, and the two side surfaces of the square open end wrench head are parallel to each other. The utility model has the benefits that the special combination tool is convenient to carry and is simple to operate, and the labor efficiency is improved.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, and particularly the special tool of maintaining oil-extracting well mouth is a kind of combination wrench of maintaining oil field shaft mouth.
Background technology
At present, in the viscous crude field manufacturing process, the oil recovery employee when patrolling well, runs into stewing driving a well daily sometimes.At this moment need to dismantle pressure meter, change the pressure meter of suitable range.Patrolling needs to be with the manometric instrument of dismounting before well sets out.Sometimes it is incomplete to carry instrument, and runs into the stewing situation that drives a well, and the oil recovery employee will go back to the toolhouse and get the manometric instrument of dismounting.Run into the instrument that needs to adjust the belt of oil pumping machine degree of tightness sometimes, the oil recovery employee needs back the toolhouse to get spanner or sleeve again.Thus, the oil recovery employee just need be with several instruments in patrolling the well process, increased working strength of workers, has influenced operating efficiency.
The utility model content
The purpose of this utility model is: a kind of oil field shaft mouth special combination instrument is provided, reduces the workpeople and carry instrument in patrolling the well process, reduce labor intensity, can finish well mouth of oil well maintaining work again, increase work efficiency, reduce labour intensity.
The technical solution adopted in the utility model is: oil field shaft mouth special combination instrument, mainly form by wrench body, main body joint and spanner plug-in unit, and it is characterized in that: wrench body is a cylinder type; Vertical welding is connected to cylinder bodily form boosting-rod on wrench body one end outer wall; The other end of wrench body is welded with the main body joint, and the main body joint is the cylinder bodily form, and the main body joint has centre bore, and the cross section of main body joint centre bore is a regular hexagon, the spanner plug-in unit can be inserted in the main body joint centre bore and the energy transfer torque; The spanner plug-in unit is made of at hand baffle plate, hexagonal prism, outer hexagon head and cubic open spanner.Two sides at baffle plate have hexagonal prism respectively, and hexagonal prism can insert in interior six sides of main body joint; Hexagon head outside the other end of a hexagonal prism has, outer hexagon head is positive hexagonal hole; The other end at another hexagonal prism has cubic open spanner at hand, and cubic open spanner is that two sides are parallel at hand.
For the ease of making and weight reduction, the plane of symmetry is arranged respectively on described two hexagonal prisms, two planes be parallel to each other and two planes vertical with the center line of outer hexagon head.
The using method of summary oil field shaft mouth special combination instrument.Consult Fig. 1.The regular hexagon centre bore of main body joint 2 can dismounting oil well nozzle.Consult Fig. 4.Also have two kinds of combinations in addition.First kind of combination: in six sides in the cubic open spanner 7 ends insertion at hand main body joint 2 of spanner plug-in unit, the outer hexagon head 6 of spanner plug-in unit can be combined into the dismounting of a lengthening arm of force, the special spanner of installation motor hex nut in the outside.Second kind of combination: outer hexagon head 6 ends of spanner plug-in unit are inserted in the main body joint 2 among six sides, and the cubic open spanner of spanner plug-in unit is combined into the demolition, installation pressure meter special spanner of the arm of force that extends at hand 7 in the outside.Because dismounting position, manometric below is a square.
The beneficial effects of the utility model: the utility model oil field shaft mouth special combination instrument, weight are half of the instrument weight sum that is equal to of its purposes, and cost price is also for being equal to half of instrument; And easy to carry, simple to operate, therefore greatly reduce oil recovery worker's labour intensity, improved efficiency.
