Specific embodiment
As shown in figure 1, the coronal plug of the present invention transfers installation tool, mainly includes lifting component 1, connecting component and shaft；
The lifting component 1 is mainly made of threaded cap 16, indicating arm 17 and spring 18；Indicating arm 17 vertically penetrates promotion
In the through-hole of component 1,18 sets of spring provide acting force of the spring on indicating arm 17, for indicating arm 17, and limit in lifting component 1
Through-hole in；The lower end of indicating arm 17 and the upper contact of connecting component；The upper end of indicating arm 17 with entire tool movement
Expose liquid level, decentralization installation process complete monitoring is realized in show tools present position.Threaded cap 16 is for sealing lifting component 1
Through-hole.
Shaft vertically passes through the shaft through-hole of connecting component, and the upper end of shaft, i.e. shaft upper body 15 connect with lifting component 1
It connects, such as by being threadedly engaged connection or clamping；The lower end of shaft is integrated between shaft lower body 14, with shaft upper body 15
Formula structure is fabricated to a root long axis；Or segmentation structure, it is fabricated separately, connects into one by screw thread or clamping, pin connection etc.
Body.The tail end of shaft lower body 14, diameter reduce, and are trapezoidal, wedge structure.
In shaft through-hole, the shaft shoulder slot 31 of the through-hole diameter is greater than equipped with size, the convex shoulder 32 being arranged on shaft is placed
In the shaft shoulder slot 31, can be moved up and down in shaft shoulder slot 31, and 32 upper and lower surfaces of the convex shoulder of shaft respectively with the shaft shoulder slot
The upper and lower side of 31 inner cavities contacts and limits, and limits the stroke up and down of shaft.In connecting component, pin hole 33 is laterally set, it should
Pin hole 33 intersects with shaft through-hole, and shear pin 5 is arranged in the pin hole 33, and shear pin 5 passes through the transverse direction being equipped on shaft
Cotter way 34 positions and limits the position of shaft by the cooperation of shear pin 5 and the transverse direction cotter way 34.In order to reduce manufacture difficulty,
Convenient for assembly manipulation, connecting component is also split production, 13 structure of the connecting component upper body 3 by being equipped with and connecting component lower body
At being linked into an integrated entity by screw thread, clamping or pin connection etc..Venthole 4 is provided in connecting component to be connected to shaft shoulder slot 31,
Convenient for being vented and keeping pressure to stablize.In connecting component upper surface, it is additionally provided with shearing finger setting instruction notch 2, is used to indicate
The position of shear pin 5, convenient for checking.
Connection sleeve 9 is connected to connecting component lower end, and specific structure as shown in the figure is connected under connecting component by bolt 6
On body 13；It connects sleeve 9 and is axially arranged along shaft, be enclosed in around shaft, the lower end connection or setting of connection sleeve 9 being capable of edges
The claw 12 for radially expanding or shrinking is the lower end that claw 12 is connected to connection sleeve 9 by fixing screws 10 as shown in the figure,
Claw 12 can be flared out by the tail end outward force of shaft lower body 14.The cooperation of the tail end of claw 12 and shaft lower body 14
There are many structures, and shown in figure be the tail end of shaft lower body 14 is trapezoidal shaft end 11, and diameter becomes smaller, for trapezoidal or wedge-shaped knot
Structure, when moving shaft up, the tail end of shaft lower body 14 releases the thrust outside to claw 12, and claw 12 is whole to contract
The diameter that a tool protrudes into the part of coronal plug is both less than coronal consent diameter, and mentioning 1 side of lifting component upwards can complete under coronal plug
Put the recycling of installation tool.
On shaft lower body 14, it is provided with shaft groove 35, shaft groove 35 is axially having certain length；Corresponding shaft is recessed
Slot 35 has been arranged radially closing piece 7, and spring 8 is provided on closing piece 7 and generates acting force of the spring, 7 front end of closing piece and shaft lower body 14
Surface contact；When shaft lower body 14 moves up and down, promotion closing piece 7 is moved radially outward；When shaft groove 35 and 7 position phase of closing piece
When corresponding (coincidence), the moving left into figure under the spring effect of spring 8 of closing piece 7 is protruded into shaft groove 35, generates unlock
Effect；When shaft groove 35 is not overlapped with 7 position of closing piece, the moving right into figure of closing piece 7 is pushed, generates locking effect.
The course of work of the invention:
Refering to fig. 1, it is necessary first to complete the decentralization of coronal plug, the shaft groove 35 and spring 8 of shaft lower body 14 are overlapped, lock
Block 7 and claw 12 all do not open, are inserted into coronal plug after tool is assembled, until connecting component lower body 13 lower surface with it is coronal
Plug connection 9 upper surface of sleeve contact, then pushes down on lifting component 1, lateral cotter way 34 and interconnecting piece on shaft upper body 15
When the pin hole 33 of part lower body 13 is overlapped, it is inserted into shear pin 5 in the pin hole 33 of connecting component lower body 13 at this time, mentions tool upwards, is locked
Movement (moving right in figure) is retracted spring 8 to block 7 from inside to outside under shaft impetus, the overhanging locking of closing piece 7 at this time
Connect coronal plug decentralization tool (coronal plug connect sleeve 9) and coronal plug, be identified through closing piece 7 and claw 12 by it is coronal beyond the Great Wall under
It clamps, the locking of implementation tool and installing component.
Referring to Fig.2, shear pin 5 fixes shaft position at this time, by mentioning after the locking of the tool of completion and installing component
Ascending part part 1 applies gravity, and entire tool is pushed to move down, and connecting component lower body 13 squeezes coronal plug connection sleeve 9, due to even
The wedge-shaped external surface shape of female connector cylinder 9, can move down and the claw 12 for squeezing coronal plug expands outward into tree body groove,
Realize the locking of coronal plug and tree body.
It needs to unlock and recycles tool after completing coronal plug and tree body locking refering to Fig. 3.Pass through bumper jar accentuated push
Dynamic lifting component 1, which moves downward, interrupts shear pin 5, and shaft can be moved up and down freely at this time.
Refering to Fig. 4, after interrupting shear pin 5, shaft is pulled up by lifting component 1, when the shaft of shaft lower body 14
When groove 35 and spring 8 are overlapped, compressed spring extends so that closing piece 7 inwardly moves, and shaft groove is protruded into the inside of closing piece 7
In 35, completes closing piece 7 and coronal plug pushes the unlock of sleeve, shaft also has left claw 12 at the same time, loses extruding force
Claw 12 to contract, the diameter that tool protrudes into the part of coronal plug is both less than coronal consent diameter, mentions 1 side of lifting component upwards
The recycling of achievable coronal plug decentralization installation tool.
Finally, it should be noted that technical side the above examples are only used to illustrate the technical scheme of the present invention and are not limiting
Case, although applicant describes the invention in detail referring to preferred embodiment, those skilled in the art should be managed
Solution, modification or equivalent replacement of the technical solution of the present invention are made for those, without departing from the objective and range of the technical program,
It is intended to be within the scope of the claims of the invention.
