Abstract

The utility model relates to an oil well maintenance of equipment, concretely relates to utilizes spanner and bolt to combine together and makes the simpler convenient well head track wrench of maintenance work for one kind, its characterized in that: including the nut on 1 top of long handle cover 2, 1 upper portion of long handle is close to the position fixing bolt 3 of nut cover 2, and the cover has top nut 4 and lower nut 5 on the bolt, and top nut 4 and lower nut separate between 5 has baffle 6, and borehole jack that baffle 6 passes through the lower extreme is on bolt 3, and the beneficial effect that can reach is: instrument processing simple manufacture, it is with low costs, can old and uselessly utilize simultaneously, it is swiftly convenient to use, respond well in on -the -spot in -service use, only with alone dismantling the well head bolt, need not beat the back -up tong, has both reduced intensity of labour, has improved the production prescription again, in use has saved manpower and materials, stops the accident potential, improves operating condition, prevents the incident, and social is showing.

Description

A kind of well head track wrench

Technical field

This utility model relates to workover equipment, is specifically related to a kind of track wrench utilizing spanner and bolt to combine and make maintenance work more simple and easy.

Background technology

At present at center during each directorial area construction operation well, well head dismounting well head bolt must be loaded and unloaded, outside being often exposed to due to well head bolt length, maintain not in place, the reason such as burn into corrosion dismounting difficulty is relatively big, and aboveground then more serious in well, steam injection, dismounting well head bolt needs many people to coordinate, beat back-up tong, it is easy to injure by a crashing object because back-up tong skidding causes, squeeze the casualty accidents such as wound. Especially thermal production well rotating shaft or turn-week, all must change well head big four, owing to well head is low or platform well and oil pumping unit base, activity space is limited, need well head surrounding to dig a big dell, expose big four, could change, need consuming just can complete for 2��3 hours, not only waste time and energy but also have a strong impact on speed of application. In order to improve production timeliness, it is ensured that personal safety, accelerating speed of application, reduce the labor intensity of workman, dismounting well head Special bolt wrench has been improved by we.

Summary of the invention

The purpose of this utility model is to solve to take a lot of work effort when keeping in repair well head bolt, it is necessary to the problem beating back-up tong.

This utility model is so to solve technical problem: include the nut sleeve on long handle top, long handle top is fixing bolt near the position of nut sleeve, being cased with top nut and lower nut on bolt, be separated with dividing plate between top nut and lower nut, dividing plate passes through the borehole jack of lower end on bolt.

Screw thread within top nut and lower nut is corresponding with the screw thread outside bolt.

Bolt is fixed on 1/3 place of long handle front end length.

This utility model can reach to provide the benefit that: tool processes makes simple, and cost is low, can waste and old utilize simultaneously, use efficient and convenient, respond well in actually used at the scene, only dismantle well head bolt with a people, back-up tong need not be beaten, both reduced labor intensity, improve again production timeliness; In use saving manpower and materials, stop accident potential, improve working conditions, it is prevented that security incident, social benefit is notable.

Detailed description of the invention

Parts title representated by each label in accompanying drawing

Long handle (1), nut sleeve (2), bolt (3), top nut (4), lower nut (5), dividing plate (6).

Embodiment 1:

A kind of well head track wrench, it is characterized in that: include the nut sleeve 2 on long handle 1 top, long handle 1 top is fixing bolt 3 near the position of nut sleeve 2, and bolt is cased with top nut 4 and lower nut 5, being separated with dividing plate 6 between top nut 4 and lower nut 5, dividing plate 6 passes through the borehole jack of lower end on bolt 3.

Embodiment 2:

Screw thread within top nut 4 and lower nut 5 is corresponding with the screw thread outside bolt 3.

Embodiment 3:

Bolt 3 is fixed on 1/3 place of long handle 1 front end length.

Embodiment 4:

Bolt 3 is fixed on 1/3 place of long handle 1 front end length.

Processing method: first with gas cutting, well head bolt is slit into two halves, the fracture of the polishing intact part of screw thread from centre, processes solder side near solid wrench 2/3 position, solid wrench is welded with section, because the power of being hit is bigger, it is therefore necessary to firm welding. On nut on screw thread, on earth, then a hole is cut in divider ends position, makes well head bolt energy traverse, then bring a nut, tool processes completes.

So, in use, utilize welding half bar well head bolt to be adjacent to well head for back-up tong stress point, inject the gap between four-way and flange for fixing point with steel plate, define need not be hand steered well head Special bolt wrench, reached safely and fast dismantle well head bolt purpose.

Claims
