Abstract
The invention belongs to union mounting and dismounting equipment and discloses a spanner. The spanner consists of a long handle, a short handle and spanner claws, wherein one end of the short handle is detachably connected with the long handle; the other end of the short handle is detachably connected with the spanner claws; each spanner claw is an arc-shaped member and is provided with a positioning groove matched with a union lug boss. The spanner can be used for screwing or unscrewing a union and also preventing breakage or deformation of the union lug boss; therefore, the spanner has the advantages of satisfying the required mechanical strength, saving raw materials for production, lowering the manufacturing cost and being simple and light in structure, hard to damage and capable of smoothly finishing a dismounting task of the union.
Description
Technical field
The present invention relates to union handling facilities field, particularly a kind of spanner.
Background technology
Union is a kind of conduit coupling facilitating installing/dismounting, be widely used in corrosive liquid conducting pipes, main under discharge pipe, intake pipeline, temporary fluid pipeline and other operating mode, carry the pipeline of fluid to connect in use, can motionless pipe and by two pipes separately.At present, the sealing of known union is that outer power is tightened onto and to a certain degree seals afterwards, more dangerous during operation under the occasion of high-low pressure test.
Because the three-jaw volume of union is large, so more difficult by common wrench holding workpiece, the operating efficiency of installing/dismounting is reduced, the instrument that currently available technology is installed, dismounting union uses is iron hammer, but iron hammer is too heavy, be not easy to carry, and iron hammer can produce larger impulsive force to union, union is caused to rupture or distortion, particularly to speedily carry out rescue work scene in blowout, because blowout scene is full of natural gas, hammer union can not be used, in order to avoid cause spark to cause the accident expansion, cause the connection of pipeline comparatively difficult.Therefore, a kind of union spanner of portable construction is provided to have important function.
Summary of the invention
In order to solve the problem that union provision for disengagement of the prior art is too heavy, cause union to rupture or be out of shape, the invention provides a kind of spanner.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of spanner, comprise long handle, short handle and pull pawl, one end and the long handle of short handle removably connect, the other end of short handle and pull pawl and removably connect; Pulling pawl is arc component, pulls on pawl and arranges and the suitable locating slot of union boss.
Short handle and long handle and short handle and pull pawl and adopt the mode that removably connects, this movable connection method can connect for pin, can realize short handle and long handle and short handle and pull pawl detachable, for the union of different sizes, that changes different size locating slot pulls pawl; Also long handle or the short handle of damage can be changed.
Because the volume of union is larger, if pull the periphery that pawl fixes union, pulling pawl needs large-sized setting, and of the present invention pulling on pawl is arranged and the suitable locating slot of union boss, so arrange and can avoid pulling pawl and be arranged to large scale, the boss only need pulling the locating slot of pawl and union is suitable; In addition, only arrange and locating slot that boss is suitable if to pull on pawl, time spanner screws and unscrews union, if strength is excessive, easily causes the boss of union to rupture or distortion thus the dismounting task of union can not be completed, and damage union and can increase cost, therefore, pawl of pulling of the present invention is designed to arcuate structure, and while locating slot fastens union boss, pulling pawl can also agree with very well with the portion perimeter of union.The pawl of pulling of spanner provided by the invention is arc component, and arranges and the suitable locating slot of union boss pulling on pawl, can complete union screw unscrew while prevent union boss from rupturing or be out of shape.
As preferably, the end of long handle arranges some roads gusset.What short handle and long handle directly contacted is gusset, instead of the terminal surface of long handle, and long handle and short handle are all not easy to be compromised.
As preferably, short handle provided by the invention is U-shaped joint pin with pulling one end that pawl is connected, and the end face of U-shaped joint pin is spill, and suitable with the curved end pulling pawl; If adopt plane contact of the prior art, contact surface straight line discontinuity, cause the unbalance stress pulled between pawl and union, in spanner use procedure, if mechanical force is very large, short handle and pull pawl serious wear, spanner provided by the invention, the end face of the U-shaped joint pin of its short handle can well agree with the curved end pulling pawl, and while mechanical force can well be transmitted, the degree of wear of spanner also drops to minimum.
As preferably, the U-shaped joint pin of short handle provided by the invention is arranged one group of through hole.
As preferably, pawl two side of pulling provided by the invention arranges two groups of through holes, mounting bush in through hole, and the material of lining is different with the material of pulling pawl, can adopt hard rigid material such as tin bronze, and the materials such as cheap material such as cast iron also can be adopted to be prepared from; Pull in the through hole of pawl two side wherein one group be connected by pin with group through hole of on U-shaped joint pin, according to needs of production, the through hole pulled on pawl two side can select suitable one group to be connected with the through hole of U-shaped joint pin; In order to avoid the wearing and tearing of equipment, be connected with the through hole of U-shaped joint pin again after mounting bush pulling in the through hole on pawl sidewall, lining adopts hard rigid material to be prepared from, be not easy to wear and tear, avoid the Contact pulling pawl through hole and short handle through hole and produce wearing and tearing, direct more resleeve after lining damages, short handle need not be changed and pull pawl, while making spanner meet required mechanical strength, save raw materials for production, reduce cost.
The invention provides a kind of spanner, this spanner long handle, short handle and pull pawl, one end and the long handle of short handle removably connect, the other end of short handle and pull pawl and removably connect; Pulling pawl is arc component, pulls on pawl and arranges and the suitable locating slot of union boss.This spanner can realize complete union screw unscrew while prevent union boss rupture or distortion; While making spanner meet required mechanical strength, save raw materials for production, reduce cost; Structure simply lightly, is not easily damaged, and completes the dismounting task of union smoothly.
