Description
Technical field
The utility model relates to the novel of a kind of back-up tong of the effective Power Tong in oil field more particularly to a kind of small dimension Power Tong
The structure of back-up tong belongs to petroleum equipment design and manufacturing technology field.
Background technique
Need to use a kind of progress of effective Power Tong to oil pipe, sucker rod, macaroni screw thread in oil well repairing operation
Upper, shackle operation, it can make the threaded connection convenient disassembly of above-mentioned tubing string.The above-mentioned general caliber of tubing string all very littles, it is required
Torque is also little, but tubing string is often replaced when operation, it is desirable that easy to carry, operation, therefore effective Power Tong is compact-sized, again
Amount is light, outer dimension is small and relative complex.Traditional Power Tong is generally open power-spider, most of using steel-casting
It is fabricated with steel alloy, steel-casting is generally used for the part of complex contour, in order to consider intensity and cast structure and opening
The needs of structure, what is be typically designed is more thick and solid, and weight also increases many, and following process difficulty also compares larger, causes
Cost is relatively high, and weight ratio is heavier, and difficulty of processing is bigger, uses relatively difficult.At present since country is to environmental requirement
It improves, if can also also increase environment more pollutions using steel-casting, therefore to low energy consumption, low cost, lighter, more environmentally friendly suitable
Power Tong for small dimension tubing string has that there is an urgent need to being able to achieve also has great social benefit and economic value.
Summary of the invention
The purpose of this utility model seeks to solve the problems, such as lightweight, the low energy consumption of small dimension Power Tong, and provides one kind
The novel back-up tong of small dimension Power Tong uses steel plate cold stamping shaped, weight to the main load-bearing part top panel and lower panel of back-up tong
1/3 or more is reduced, work work load is light and cold stamping shaped high-efficient, is easy to produce in batches, stable product quality, to ring
Border influences also small.
To achieve the goals above, the utility model is implemented by the following technical programs: the program include top panel, below
Plate, back-up tong head clamping assembly, back-up tong head circle, duplicate gear, oil cylinder with gear racks transmission mechanism, fulcrum bearing, back-up tong head clamping assembly packet
Containing jaw plate frame, jaw assembly, ramp, oil cylinder with gear racks transmission mechanism includes cylinder seat, rack gear, piston, the upper surface of described plate, lower panel
It is all Steel Sheet；The back-up tong head circle is fixed in the above between plate and lower panel, and in the both ends of the surface of back-up tong head circle
It is respectively equipped with the annular key of protrusion, is respectively equipped with recessed annular groove, the annular key in back-up tong head circle on top panel and lower panel
It is embedded in the annular groove of top panel and lower panel and plays support and positioning action；The ramp is fixed in back-up tong head circle,
It can be rotated between jaw plate frame plate located in the above and lower panel；Cylinder seat in the oil cylinder with gear racks transmission mechanism is fixed on
Between top panel and lower panel, the rack gear passes through the tooth engagement on duplicate gear and jaw plate frame；On the back-up tong tail portion
Fulcrum bearing is equipped between panel and lower panel, fulcrum bearing upper and lower end is equipped with step surface and positioning spindle nose, and top panel and lower panel are logical
Cross respective location hole respectively with position spindle nose clearance fit in fulcrum bearing, top panel and lower panel be close in fulcrum bearing respectively,
Leave from office terrace and axially position fastening.
In a kind of novel back-up tong of above-mentioned small dimension Power Tong be it is further mitigate weight, the top panel and following
Plate is aluminum alloy plate materials.
Top panel and lower panel steel plate use cold punching pressing formation in the utility model, and the mechanical performance of steel plate is better than same
Steel-casting, in the case of plate thickness reduces 1/3 than conventional steel-casting wall thickness, intensity can increase instead.And in stamping process
In, shape, opening, most of hole can stamp out, and following process amount very little once stamps out and, and precision and size also can
Guarantee that unification with accurately, is convenient for mass production.Therefore the utility model meets the lightweight of small dimension Power Tong, low energy consumption
Requirement, not only environmental protection but also alleviate weight, reduce cost, and intensity increases instead, social benefit is huge, and economic benefit can
It sees.
