Abstract
The present invention relates to oil drilling corollary equipment technical fields, specifically disclose a kind of novel hinge pin formula chuck, the slips of shell and inside clamping oil pipe, casing or drilling rod including outside, it is provided with liner between the shell and slips, realizes the chuck size of different size by increasing or decreasing the number of liner to meet the requirement of the size of corresponding oil pipe, casing or drilling rod.The beneficial effects of the present invention are: 1, it by replacement slips body and increases or decreases liner meets the oil pipe of various sizes, casing or the clamping effect of drilling rod, the specification span of chuck is big, has in oil equipment and has good promotion and practical value；2, structure is simple, easy to disassemble.
Description
Technical field
The present invention relates to oil drilling corollary equipment technical fields, and in particular to a kind of novel hinge pin formula chuck.
Background technique
In Process of Oil Well Drilling, oil pipe, casing or drilling rod are clamped all the time by chuck.Under normal conditions, a kind of specification
The clamping caliber of chuck is very limited, and the chuck of small dimension is generally not applied for the caliber of big specification, the chuck of big specification
The caliber of small dimension is not suitable for it, user usually adapts to various sizes of oil pipe, casing by buying the chuck of different size
Or drilling rod.
Summary of the invention
In view of the deficiency of the prior art, the present invention provides a kind of novel hinge pin formula chuck, by increasing or
It reduces liner and converts slips body quantity to realize the chuck size of plurality of specifications.
The technical solution adopted by the invention is as follows: a kind of novel hinge pin formula chuck, shell and inside folder including outside
The slips of oil pipe, casing or drilling rod is held, is provided with liner between the shell and slips, by the number for increasing or decreasing liner
To realize the chuck size of different size to meet the requirement of the size of corresponding oil pipe, casing or drilling rod.
Further, the number of the liner can be one or more, the specific number of liner according to oil pipe, casing or
The size of drilling rod is set.
Further, the slips includes multiple slips bodies, and the specific number of the slips body is according to oil pipe, casing or brill
The size of bar increases or decreases.
Further, the inside of the shell and the two sides of liner are in the tilt angle of 1:3 or 1:4.
Further, the inner wall setting of the shell is fluted, and what the liner was in contact with shell is provided with convex on one side
Platform, groove is corresponding with boss to be arranged and is bolted between groove and boss.
Further, the interior lining is equipped with bolt hole, is fastened by bolts between two adjacent liners.
The beneficial effects of the present invention are: 1, it by replacement slips body and increases or decreases liner meets various sizes
Oil pipe, casing or drilling rod clamping effect, the specification span of chuck is big, has in oil equipment and promotes well and practical
Value；2, structure is simple, easy to disassemble.

Specific embodiment
In order to which the purpose of the present invention, technical solution is more clearly understood, with reference to the accompanying drawings and examples to the present invention
It is described in further detail, it should be understood that described herein the specific embodiments are only for explaining the present invention, is not used to the present invention
The restriction of protection scope, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention.
Fig. 1-Fig. 5 is please referred to, a kind of novel hinge pin formula chuck is specifically mounted on turntable.Shell 1 including outside and
Inside clamps the slips 4 of oil pipe, casing or drilling rod 5, and liner 6 is provided between shell 1 and slips 4, by increasing or decreasing
The number of lining 6 and change the number of 4 upper slips body 7 of slips to realize the chuck size of different size, to meet corresponding oil
The size requirement of pipe, casing or drilling rod 5.
In the present embodiment, for ease of description, two are set by liner 6, is specifically divided into liner I 2 and liner II 3.
Chuck successively includes shell 1, liner I 2, liner II 3 and slips 4 from outside to inside, and slips 4 includes multiple slips bodies 7, slips body
7 number is arranged according to the size of oil pipe, casing or drilling rod 5, to achieve the effect that clamp oil pipe, casing or drilling rod 5 just.Shell
The inner wall and liner I 2 of body 1, the two sides of liner II 3 are in the tilt angle of 1:3 or 1:4, in order to slips 4 clamp oil pipe,
Casing or drilling rod 5.Fluted 8 are arranged on the inner wall of shell 1, the one side that liner I 2 is in contact with shell 1 is equipped with boss, groove 8
It is correspondingly arranged with boss and is bolted between groove 8 and boss, prevent liner I 2 from rotating or squeezing to 1 top of shell,
Bolt hole 9 is equipped on liner I 2, liner II 3 again, is fastened by bolts between liner I 2 and liner II 3.
In general, the number of liner 6 can be one or more, the specific number of liner is according to oil pipe, casing or drilling rod 5
Size depending on, the number of 4 upper slips body 7 of slips also according to oil pipe, casing or drilling rod 5 specific size and change.
