Description
Technical field
The utility model is related to oil production equipment fields, and in particular to a kind of friction transposition cylinder.
Background technology
Friction transposition cylinder is tested for petroleum gas underground, in the rotating circulating inversion mechanism of exploitation tool.It is existing
It rubs
It wipes transposition cylinder and uses split structure, detachably, use clip and spring ring mechanism in middle interconnecting piece point, profit
Use clip
Transposition set is connected, spring ring is used for banding clip.The deficiency of this design structure is：Radially there are three layers points
Cloth,
Small size tool is difficult to realize in limited space；And exist in addition to being rotated about axis, to remaining five freedom
Degree limitation is not
Thorough problem has axial gap play that can make fortune when until making transposition set mechanism assembly there are concentricitys poor, movement
Dynamic accumulation misses
Difference is increasing, and rotation is dumb card resistance etc., influences rotation transposition accuracy, poor reliability.
Utility model content
The technical problems to be solved in the utility model is to have overcome the deficiencies of the prior art and provide a kind of friction transposition cylinder,
It adopts
With integrated design scheme, mechanism assembly number is simplified, while ensureing to rotate about the axis flexible, is eliminated
Movement
Gap；Whole concentricity improves；Break original split type fixed mode, improves rotation transposition performance, work
Make reliable.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of friction transposition cylinder, including cylinder, should
Cylinder upper end is equipped with friction head, and engaging slot is equipped in cylinder periphery, which is equipped with location hole；It is described
Friction head
It is equipped with commutation hole, triangle block is equipped on the downside of the commutation hole；Exhibition of the commutation hole in friction head periphery
Open figure
Socket and lower socket are included, the triangle block is between upper socket and lower socket.
Further improved as the utility model, the upper socket is coaxially disposed with one of engaging slot, the card
It closes
The equivalent width of the width of slot and upper socket.
Further improved as the utility model, the barrel lenght is 1.5~2.5 times of friction head length.
Further improved as the utility model, expanded angle of the commutation hole on friction head periphery is ranging from
35 °~55 °.
Due to the application of the above technical scheme, the utility model has following advantages compared with prior art：
Using integrated design scheme, mechanism assembly number is simplified, while ensureing to rotate about the axis flexible, is disappeared
In addition to
Movement clearance；Whole concentricity improves；Break original split type fixed mode, improves rotation transposition property
Can, work
Reliably.
Description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Fig. 1 is the novel structural schematic diagram of the utility model；
Fig. 2 is the novel cross-sectional structure schematic diagram of the utility model；
Fig. 3 is the novel commutation hole deployed configuration schematic diagram of the utility model.
In figure：1, friction head；2, upper socket；3, lower socket；4, triangle block；5, cylinder；6, location hole；
7, engaging slot.
Specific implementation mode
With reference to specific embodiment, the utility model is described in further detail.
A kind of friction as shown in Fig. 1 to Fig. 3 replaces cylinder, and 5 upper end of cylinder is equipped with friction head 1, outside cylinder 5
Engaging slot 7 is equipped in disc, which is equipped with location hole 6；Engaging slot 7 plays positioning and fixed function, ensures
Friction transposition cylinder orientation remains unchanged when without ex-situ operations.Location hole 6 and oil recovery bar or the corresponding vacancy bar of test
Cooperation ensures positioning accuracy.
Friction head 1 is equipped with commutation hole, and triangle block 4 is equipped on the downside of the commutation hole；Hole commutate in friction head outer circle
The displaypattern in face includes upper socket 2 and lower socket 3, triangle block 4 be located at upper socket 2 and lower socket 3 it
Between.Drive rod on driver is driven by the conversion driving transposition cylinder rotation between upper socket 2 and lower socket 3
Other components realize ex-situ operations.
Upper socket 2 is coaxially disposed with one of engaging slot 7, the width of the width of engaging slot 7 and upper socket 2
Unanimously, facilitate the correction of exchange parallactic angle degree.
5 length of cylinder is 1.5~2.5 times of 1 length of friction head, preferably 2 times settings, and can be according to wanting
It asks and adjusts multiple value in the case of proof strength.
Commutate expanded angle ranging from 35 °~55 ° of the hole on friction head periphery, which determines that transposition cylinder is every
Secondary transposition angle.
The specific application example that the above is only the utility model does not constitute the scope of protection of the utility model any limit
System.
Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all falls within the utility model rights protection model
Within enclosing.
