Well-mouth theft-prevention valve special spanner of the present utility model, by ratchet carriage, ratchet, spring, gripper shoe and handle are formed, two described gripper shoe hollow outs have hole clipping and symmetrical parallel arrangement, the termination of described handle is fixed in the middle of two gripper shoes, the end tail of this handle is hinged with flexible handle, described ratchet to be fixed between two gripper shoes by fixed axis activity and the pawl tail of this ratchet is fixedly connected with one end of spring respectively with the termination of handle, the pawl head of ratchet is meshed with the gear teeth of ratchet carriage, axially be actively tied between two gripper shoes in the hole clipping that this ratchet carriage is socketed on two gripper shoes.Well-mouth theft-prevention valve special spanner of the present utility model, structure is simple, easy to use.By the control of ratchet to ratchet carriage, avoid the complicated processes needing repeatedly to be set with, to extract out spanner.The flexible handle installed additional, can avoid due to spanner slippage, hand is encountered on well head hardware, damages, substantially increase job security.
Description
Technical field
The utility model relates to a kind of spanner, refers more particularly to a kind of well-mouth theft-prevention valve special spanner.
Background technology
In oildom, the event of theft crude oil is often had to occur, in order to prevent crude oil stolen, the valve of present oil well all adopts valve for guarding against theft, opening anti-theft valve then needs special box spanner, but box spanner is a kind of solid wrench, and it can not rotate neatly, all needing when unscrewing or tighten valve for guarding against theft constantly to take away from valve again on cover at every turn, using very inconvenient.And because the ring flange of pipeline is all very large, the space between itself and spanner is just very little, hand, when using spanner, accidentally will be clipped to by both, or the slippage when using box spanner, hand is met on other hardwares injured.
Summary of the invention
Well-mouth theft-prevention valve special spanner of the present utility model is exactly that a kind of structure proposed to solve the problem is simple, spanner easy to use.
Well-mouth theft-prevention valve special spanner of the present utility model, be made up of ratchet carriage, ratchet, supportive body and handle, described supportive body is by gripper shoe I and gripper shoe II is symmetrical parallel rearranges, in the hole clipping that gripper shoe I and gripper shoe II center all have symmetrical hole clipping, ratchet carriage to be axially socketed on supportive body and the ratchet of ratchet carriage between gripper shoe I and gripper shoe II; One end of handle to be placed in the middle of gripper shoe I and gripper shoe II and to fix; The ratchet being fixed between gripper shoe I and the gripper shoe II and termination of the pawl tail of this ratchet and the handle two ends of linking springs, the pawl head of ratchet and ratchet carriage respectively by fixed axis activity in the middle part of described ratchet fastens.
As further improvement of the utility model, described ratchet carriage is formed by a sleeve is fixed with the uniform gear teeth in its outer wall ring week.
As further improvement of the utility model, the end tail of described handle is hinged with flexible handle.
As further improvement of the utility model, described flexible handle is 90 ° ~-90 ° relative to the rotational angle of handle.
Well-mouth theft-prevention valve special spanner of the present utility model, structure is simple, easy to use, by the control of ratchet to ratchet carriage, avoids the complicated processes needing repeatedly to be set with, to extract out spanner; The flexible handle installed additional, can avoid due to spanner slippage, hand is encountered on well head hardware, damages, substantially increase job security.

Fig. 1 is the longitudinal sectional view of well-mouth theft-prevention valve special spanner of the present utility model;
Fig. 2 is the three-dimensional structure diagram of well-mouth theft-prevention valve special spanner of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Well-mouth theft-prevention valve special spanner of the present utility model, be made up of ratchet carriage 1, ratchet 2, supportive body 4 and handle 5, described supportive body 4 is by gripper shoe I 7 and gripper shoe II 8 is symmetrical parallel rearranges, in the hole clipping that gripper shoe I 7 and gripper shoe II 8 center all have symmetrical hole clipping, the ratchet carriage 1 adapting to ratchet carriage 1 to be axially socketed on supportive body 4 and the ratchet of ratchet carriage 1 between gripper shoe I 7 and gripper shoe II 8; One end of handle 5 to be placed in the middle of gripper shoe I 7 and gripper shoe II 8 and fix, the hinged flexible handle 6 of the other end; Flexible handle 6 can rotate relative to handle 5, and its rotational angle is 90 ° ~-90 °, can perpendicular to the plane at gripper shoe 4 place.
Sleeve part is each passed through the hole clipping of gripper shoe I 7 and gripper shoe II 8 by this ratchet carriage 1, ratchet part is held on therebetween by gripper shoe I 7 and gripper shoe II 8, can bearing be combined with between the hole clipping of ratchet carriage 1 and gripper shoe I 7 and gripper shoe II 8, ratchet carriage 1 can be axially moved between gripper shoe I 7 and gripper shoe II 8.
Be fixed between gripper shoe I 7 and gripper shoe II 8 by fixed axis 9 activity in the middle part of described ratchet 2, other positions can be that axle freely rotates around fixed axis, and the ratchet of the termination of the pawl tail of this ratchet 2 and handle 5 two ends of linking springs 3, the pawl head of ratchet 2 and ratchet carriage 1 respectively fastens.
In order to make ratchet 2 can firmly pin ratchet carriage 1, the distance of the pawl tail of ratchet 2 and the termination of handle 5 is wanted to make the pawl head of ratchet 2 can not do not departed to during highest point by ratchet carriage 1 at it.
The using method of described well-mouth theft-prevention valve special spanner of the present utility model is as follows:
By this well-mouth theft-prevention valve special spanner ratchet carriage 1 be placed on the nut of valve for guarding against theft, again flexible handle 6 is pulled to operating personnel direction vertical with handle 5, hold flexible handle 6, with sleeve be axle clockwise or counterclockwise movement, if now ratchet 2 pins ratchet carriage 1, then ratchet carriage 1 is equivalent to a fork spanner, thus unscrews nut.This well-mouth theft-prevention valve special spanner only need be rotated a bit of distance by operating personnel, counter motion is got final product after unscrewing nut, make ratchet 2 depart from from the ratchet ratchet carriage 1, unlock ratchet carriage 1, ratchet carriage 1 nut in the inner all can not be tightened along with the reset of handle 5 again.Handle 5 repeats motion on last stage again until the nut of valve is unscrewed completely after resetting.
Tighten the nut of same valve, only need the nut upset of this well-mouth theft-prevention valve special spanner being inserted in valve, then carry out operating according to step above.
Well-mouth theft-prevention valve special spanner of the present utility model, is controlled by ratchet 2 pairs of ratchet carriages 1, avoids the complicated processes needing repeatedly to be set with, to extract out spanner.And each operation spanner can ignore the obstruction of arm, only need to move back and forth in a bit of distance and can unscrew nut, reach time saving and energy saving object.The flexible handle installed additional, can avoid due to spanner slippage, hand is encountered on well head hardware thus damages, and improves job security.
