Abstract

The entitled ring spanner of the present invention.Present invention design belongs to the technical field of hand-held tool spanner, specifically a kind of instrument that reciprocal continuous spinner can be achieved.Using screw sheet as rotating shaft, screw outer surface is acted on ratchet, screw is bitten under the collective effect of clamp handle, annular sleeve and ratchet, then applied torsion moment in further rotating for clamp handle on screw under effect.During convolution, clamp handle revolution rotates with ratchet to radius extroversion, the space for allowing open screw to be needed when rotating.This instrument mainly solves the spinner of large scale screw and the problem that links closely.Particularly narrow space, conventional pipe wrench, spanner is want during spinner, otherwise often size does not reach, otherwise it is limited to space, it is impossible to work.Present invention mainly solves the continuous spinner of small space and work of linking closely.Certainly, it is also equally applicable that the unrestricted place in space, which is used,.Corresponding annular sleeve is changed for different screw matchings, you can realize and the spinner of various sizes of screw is worked.

Description

Ring spanner

Technical field

Present invention design belongs to the technical field of hand-held tool spanner, specifically a kind of instrument that continuous spinner can be achieved, Spinner mainly for large scale screw and link closely.

Large-sized screw often Relatively centralized, narrow space, existing instrument is as usual to regulate pincers, and spanner is want in spinner During realize efficient operation, or often size do not reach, or be limited to space, it is impossible to put to good use.This instrument is good This problem is solved, continuous reciprocal spinner can be realized in small space, and certain torque value can be reached.Using During substantially increase timeliness, the labor intensity of personnel is reduced well, so as to create bid value.The present invention can be fine Solution petroleum industry, heavy-duty machinery, the quickly upper shackle for the BIG SIZE BOLTS used in heavy construction and work of linking closely in advance.

Background technology

By taking petroleum industry as an example, in industry in generally require to use fastening between large-sized screw, such as blowout preventer, well The fixation of frame, these places are often again in narrow space, or are suspended in the air, in this process of the full screw thread of rotation, or dismantle When needing to outward winding screw after moment of torsion, or conventional tool is limited to size, or operating space is difficult to play a role.Present each factory Instrument provisioned in family is usually hydraulic torque wrench and striking wrench, and both is not originally asked when fastening and dismantling moment of torsion Shackle ability is strong on topic, hydraulic torque wrench, and striking wrench cost is relatively low；But both has inborn shortcoming again：Hydraulic spanner Dead weight is larger, and dismounting is hard, and rotary speed is very slow, and efficiency is very low, and striking wrench needs repeated disassembled and assembled, itself quality Not light, particularly large-sized screw, the labor intensity of personnel is larger.Although traditional spanner ratchet can continuously rotate, It is that can only often bear less moment of torsion, and for being also smaller screw.Under this background, ring spanner is devised. This instrument has advantages below：, can back and forth be worked continuously as ratchet spanner；Cost is low, and material therefor is common steel； Easily maintain, member replacing is simple, and only one of which bearing pin and headgear inner surface need lubricating maintenance；For various sizes of spiral shell Silk, only need to change the annular sleeve of matching；Convenient operation, gross mass is lighter, can meet certain upper break-out torque requirement.This Instrument is not limited solely to petroleum industry, as long as large-sized this instrument of screw is applicable.

The content of the invention

It is an object of the invention to provide one kind is simple in construction, the instrument of continuous spinner can be achieved, primarily directed to large scale Screw.The similarly suitable small size screw of this instrument principle, it is only necessary to which fitting dimension is accordingly turned down.

The technical scheme is that：

1st, this instrument includes annular sleeve, bearing pin, clamp handle, ratchet and its lock screw composition.

2nd, this instrument ratchet angle：The angle on ratchet leading portion top is between 65 ° to 85 °, and the occlusion angle of front lower portion is 120°。

3rd, it is using being characterized in：

(1) before use, loading onto corresponding annular sleeve, ratchet direction is inclined to the direction that screw needs to rotate, to use When clamp handle is got rid of to the opposite direction of spinner ratchet is biased to outside the inner circle of annular sleeve, then annular sleeve is enclosed on the outside of screw, so Clamp handle is moved to the spinner direction of needs afterwards, " tooth " of ratchet front end bites screw outer rim and then embrace screw, is further continued for Rotation is just applied torsion moment on screw.

(2) toward opposite direction rotary handle, screw promotes ratchet leading portion away from annular sleeve inner circle, so whole pliers The next position just can be turned to, repeats (1) to reach the purpose of continuous rotary screw.

Embodiment：

Part function is introduced：

Annular sleeve：Screw outer rim is acted on, rotational trajectory is provided for reciprocating action, side is provided to sting tight screw during upper shackle Xiang Li.It is to follow each size screw external diameter to change, and performs standard GB/T4392-1995 and (taps fork spanner and tap beautification and pull Hand), smooth circle simply is made in the percussion spanner inner ring of the correspondingly-sized.

Clamp handle：It using the pin-and-hole of annular sleeve as the center of circle, can be rotated in setting range, promote ratchet to be revolved to painstaking direction Turn, until biting screw.

Main pin：Axis of rotation is provided for occlusion process, fulcrum power is provided during occlusion.

Ratchet：It is responsible for biting screw outer surface, during counter-rotating, retreats to outside the inner circle of headgear and allow in clamp handle counter-rotating Open behind space, so that whole pliers is rotated to occlusal position next time.It is any that the unique shape of front end can be engaged screw Position.Its same size follows screw external diameter to change.

Ratchet fixed screw：Fixed pawl, makes it arbitrarily not shifted one's position after installing, and is loosened i.e. when changing ratchet Can.

Operation principle：As illustrated, operationally, annular sleeve is on the outside of the square toes of screw six, using six square toes outward flanges as rail Mark can be rotated freely.With the rotation of clamp handle, pawl rotation is whole after screw is tightly bitten by the anti-slop serrations of ratchet front end Individual pliers produces moment of torsion with screw one entirety of formation under clamp handle B continuation effect.

Claims
