Description

New type power tong transfer device
Technical field:
A kind of new type power tong transfer device, particularly oil drilling and workover treatment instrument.
Background technology:
Power tongs is one of bank head machinery equipment in drilling well and the well workover process, and its completion tightening and dismantling tubing string, comprises rotary tong, casing tong and tubing tongs.Power tongs is installed in shaft mouth operation platform (rig floor and base) and goes up the plane.At present the power tongs of land rig and workover rig well head all is semi-automatic, the sending to, return of power tongs; Clamp, unclamp; Last button and shackle are manual operation; Need operative employee 1 people, well head worker 2 people.
Conventional power tongs is sent to, is return with oil cylinder, and an end of oil cylinder connects power tongs, and the other end is fixed on the column through a cutting ferrule.During power tongs work, oil cylinder stretches out, and promotes tong to well head; When power tongs is not worked,, make things convenient for shaft mouth operation worker operation, need power tongs, boosting oil cylinder and oil cylinder be installed column and dismantle in order to reserve well head operating space (with the well head is that central diameter is in the scope of 3000mm, does not allow obstruction).This structure send clamp device disassemble and assemble work amount big, time is long, the coupling part is through after repeatedly dismantling, installing, supporting capacity reduces even lost efficacy.The oil cylinder boosting, the sealing ring of oil cylinder often lost efficacy, and leakage of oil is sprayed on the rig floor face, skids easily above not only the shaft mouth operation worker steps down in and falls, and causes security incident, and the cleaning difficulty, contaminated environment; The maintenance difficult of oil cylinder often need be disintegrated cylinder barrel sealing ring is installed, and maintenance time is long, delays operation.
Summary of the invention:
The goal of the invention of the utility model power tongs transfer device is to tong transfer device powered by conventional energy the problem that need dismantle with use to be installed to improve, provide a kind of safe, make things convenient for and power tongs transfer device efficiently.
The utility model is to realize above-mentioned purpose through following technical scheme:
A kind of new type power tong transfer device; Form by drive part and running part; It is characterized in that: drive part comprises bearing one, bearing two, cylinder, bearing pin one, bearing pin two, bearing pin three, bearing one, bearing two, cursor; Cylinder is connected between bearing one, the bearing two through bearing pin one, bearing pin two, and bearing one, bearing two are installed in cursor up and down on the axle at two ends, and bearing pin three is installed on the pin-and-hole of cursor; Link to each other with running part, drive part is connected on the derrick through bearing one, bearing two; Running part comprises compositions such as bearing pin four, bearing pin five, swing arm, adjusting rod, otic placode; Swing arm connects power tongs through an end of adjusting rod; The other end with link through bearing pin three and cursor; Described cylinder liner is connected with bearing one, bearing two, and the cylinder piston end links to each other with otic placode on the cursor.Be evenly equipped with row's pin-and-hole on the described cursor, scalable swing arm, power tongs height; Cursor is installed bearing, bearing up and down; Described adjusting rod is enclosed within the swing arm, and there is row pin-and-hole, the length of adjusting rod as required the inside.
During operation, stretch out or regain through cylinder and drive cursor and rotate, the rotation of cursor drives swing arm around axis swing, and stretching out and regaining the drive power tongs of cylinder is in operating position and off-position.
The utility model compared with prior art has following beneficial effect:
1. because power tongs drive part structure is installed on the derrick, swing arm is fixed on the cursor, is uniformly distributed with a plurality of pin-and-holes on the cursor and makes power tongs setting height(from bottom) scalable; Swing arm is provided with adjusting rod makes the distance adjustment of power tongs and well head convenient, when power tongs is not worked, does not need dismounting, and efficient is high, and the well head operating space is big on the rig floor face, and safety is good.
2. when complete machine was moved, cylinder, bearing, cursor, adjusting rod did not need dismounting, and resettlement efficient is high.

Fig. 2 is this transfer device duty front view;
Fig. 3 is this transfer device off working state vertical view;
Fig. 4 is this transfer device off working state front view;
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe:
In Fig. 1, Fig. 2; New type power tong transfer device; Be made up of drive part and running part, drive part comprises bearing one (9), bearing two (11), cylinder (8), bearing pin one (15), bearing pin two (16), bearing pin three (17), bearing one (12), bearing two (13), cursor (14), and cylinder (8) is connected between bearing one (9), the bearing two (11) through bearing pin one (15), bearing pin two (16); Bearing one (12), bearing two (13) be installed in cursor (14) up and down two ends the axle on; Bearing pin three (17) is installed on the pin-and-hole of cursor (14), links to each other with running part, and drive part is connected on the derrick on (1) through bearing one (9), bearing two (11); Running part comprises bearing pin four (4), bearing pin five (6), swing arm (7), adjusting rod (5), otic placode compositions such as (10), and the end of swing arm (7) through adjusting rod (5) connects power tongs (3), the other end with link through bearing pin three (17) and cursor (14).Described cylinder (8) cylinder sleeve is connected with bearing one (9), bearing two (11), and cylinder (8) piston end links to each other with otic placode (10) on the cursor (14).Be evenly equipped with row's pin-and-hole on the described cursor (14), scalable swing arm (7), power tongs (3) are highly; In described adjusting rod (5) was enclosed within swing arm (7), there was row pin-and-hole, the length of adjusting rod (5) as required the inside; At cursor (14) bearing (12), bearing (13) are installed up and down.
