Abstract
The utility model relates to an oil pipe tong, which is used for assembling and disassembling flow string in oil fields. The utility model comprises a tong rod, a pin shaft, and tong head, wherein, the tong rod and the tong head are connected through the pin shaft. The utility model is characterized in that the connection end between the tong rod and the tong head is provided with a blind hole; the blind hole is provided with a spring rod; one end of the spring rod extends into an inner hole of the tong rod, and the other end extends into the inner hole of the tong head; alloy steel tong teeth are inlaid on the end part of the tong head. The tong head and the tong rod adopt equal intensity structures with an H-shaped profile and various sections. A groove on the front end of the tong rod and a gap on the back of the tong head make the angle of the swing of tong head controlled at about 10 DEG. The utility model can be clamped and loosened conveniently. The utility model has the advantages of reliable use, high efficiency, long service life, simple structure, low cost, and simplified manufacture processes.
Description
The utility model relates to a kind of tubing tongs that is used for oil field flow string loading and unloading.
The general pipe wrench of the existing use in oil field at present uses very inconvenient, need be according to the different-diameter adjustable pipe jaw footpath of oil pipe, because pipe wrench is hung oil seriously during work, regulate to get up usually to be restricted, reduced operating efficiency, general pipe wrench is difficult for chucking simultaneously, and service life is short, complex structure, cost is higher.
The purpose of this utility model provides a kind of chucking, unclamps conveniently, uses tubing tongs reliable, that efficient is high, the life-span is long.
For achieving the above object, the technical solution of the utility model is: a kind of tubing tongs, comprise claw beam, bearing pin, binding clip, claw beam is connected by bearing pin with binding clip, it is characterized in that claw beam and binding clip join the end be provided with blind hole, spring lever is housed in the blind hole, spring lever one end stretches into the claw beam endoporus, the other end stretches into the binding clip endoporus, and alloy pucellas tooth is embedded in the end of binding clip.Binding clip, claw beam adopt " I shape " section variable cross-section equal strength structure, and end slot and gap, binding clip back are controlled at about 10 degree the binding clip swing before the claw beam.
The utility model has been cancelled numerous and diverse retaining mechanism owing to adopt said structure, makes whole pipe wrench simple and direct, practical; Replace extension spring with spring lever, not only use reliably, make easyly, and enough auto-lock functions are arranged; Adopt inserted pincers tooth, quick, firm when making pipe wrench clamping oil pipe, because the pincers tooth adopts the manufacturing of high duty alloy tool steel, so durable in use especially; Binding clip, claw beam are all taked the design of I shape section variable cross-section equal strength, have improved the utilization rate of material, have reduced manufacturing cost; By the gap at reasonable Arrangement claw beam groove and binding clip back, decided the movable relatively scope of claw beam, binding clip from ceiling structure, cancelled the trouble that structures such as original limited block are brought to manufacturing.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further: a kind of tubing tongs, comprise claw beam 1, bearing pin 3, binding clip 4, claw beam 1 is connected by bearing pin 3 with binding clip 4, claw beam 1 joins to holding with binding clip 4 and is provided with blind hole, spring lever 2 is housed in the blind hole, spring lever 2 one ends stretch into claw beam 1 endoporus, and the other end stretches into binding clip 4 endoporus, and alloy pucellas tooth 5 is embedded in the end of binding clip 4.Binding clip, claw beam adopt " I shape " section variable cross-section equal strength structure, and end slot and gap, binding clip back are controlled at about 10 degree the binding clip swing before the claw beam.The moment that acts on claw beam during use tightens oil pipe by the pincers tooth of rod end shoulder plane and binding clip, and this moment, spring lever was in case of bending, and its bounce makes tubing tongs be in self-locking state and blocks the jail on oil pipe.The pipe wrench card must be tight more more for opplied moment when twisting pipe, when unclamping, need only oppositely just throw off from oil pipe with very little solenoid pincers.
