Preferably, end of the cursor away from the sleeve is provided with for driving the dismantling device to turn after instrument clamping
Dynamic rotary head.
Preferably, the cross section of the rotary head is polygon.
Implement oil return pipe dismantling device of the present utility model, have the advantages that:The utility model dismantling device
Cursor can will not take big spatial dimension along protruding between the rocking arm shield of diesel engine cylinder block during rotation, can be easily
Drive locking nut rotate, make the dismounting enhanced convenience of locking nut quick.
Brief description of the drawings

Embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed
Illustrate embodiment of the present utility model.
Because of the cylinder head design structure of nuclear power station diesel engine, the locking nut 12 of oil return pipe 1 of diesel engine is located at the two of cylinder body and shaken
Between the crack of arm shield, need to remove the locking nut 12 of oil return pipe 1 in maintenance.
With reference to shown in Fig. 1 to Fig. 4, the oil return pipe dismantling device in one preferred embodiment of the utility model includes sleeve 21
And cursor 22.The opening 211 run through is offered on the side wall of sleeve 21 vertically, allows oil return pipe 1 laterally to snap onto set
In cylinder 21, the inwall facial contour of sleeve 21 is corresponding with the profile of the locking nut 12 of oil return pipe 1, allows 21 sets of sleeve to be set to locking screw
On mother 12.21 sets of sleeve, which is set to after locking nut 12, to be rotated by cursor 22 with moving sleeve 21, and locking nut 12 is removed
Or locking.
One end of cursor 22 is connected with one end end of sleeve 21, axially extended setting of the cursor 22 along sleeve 21,
Band moving sleeve 21 is rotated, with rotation lock nut 12.Cursor 22 can along protruding between the rocking arm shield of diesel engine cylinder block,
Big spatial dimension will not be taken during rotation, can easily drive locking nut 12 to rotate, allow locking nut 12 dismounting more
It is convenient and swift.
The section of sleeve 21 is C-shaped, both can guarantee that oil return pipe 1 can be caught in, moreover it is possible to which in sleeve, 21 sets are set to locking nut 12
Afterwards, it can well coordinate with locking nut 12, prevent from skidding between locking nut 12 in rotation process.In other embodiment
In, the profile of sleeve 21 is alternatively U-shaped.
Preferably, the internal face section profile of sleeve 21 and the section form fit of locking nut 12, allow sleeve 21 to be arranged
The cooperation in leading surface and face after to locking nut 12, lifts the stability after being arranged, and prevents from skidding.In other embodiments, cover
The internal face of cylinder 21 may also set up multiple snap fit tabs corresponding with the outer peripheral surface of locking nut 12, by multiple points and face
Coordinate, drive locking nut 12 to rotate.
In certain embodiments, cursor 22 is in rod-like structure, in other embodiments, and cursor 22 or section are
Polygonal column structure, when section is polygon, 2 turns of dismantling device is driven after can coordinating by instrument and cursor 22
It is dynamic, drive locking nut 12 to rotate.
In order to which oil return pipe 1 will not interfere between cursor 22 when dismantling device 2 is rotated, cursor 22 and set are also allowed for
Connected between cylinder 21, the axis of the axis runout sleeve 21 of cursor 22 allows the end face of cursor 22 and sleeve 21 to be welded to connect.
In other embodiments, the axis of cursor 22 also can be in certain small angle with the axis of sleeve 21.
End of the cursor 22 away from sleeve 21 is provided with the rotary head 221 for driving dismantling device 2 to rotate after instrument clamping,
Rotary head 221 can stretch out the crack of two rocking arm shields of cylinder body, when in use, and instrument is protected without extending into two rocking arms of cylinder body
Dismantling device 2 and locking nut 12 can be driven to rotate between the crack of cover.
The cross section of rotary head 221 is polygon, and such as triangle, hexagon are easily set to the set such as conventional spanner
Rotary head 221 drives dismantling device 2 to rotate, or other polymorphic structures, can have instrument to drive dismantling device 2 to rotate i.e.
Can.
It is to be appreciated that above-mentioned each technical characteristic can be used in any combination and unrestricted.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
