For the fixation of the screw pump of tripping in oil well.
Background technology
Subsurface progressive cavity anchor substantially has support card tile style tubing anchor, turnover plate type tubing anchor, hydraulic tubing anchor at present
With torque anchor etc..Support card tile style tubing anchor is completed to be anchored by pressuring oil pipe, easily causes oil pipe severe bends, causes oil pipe radially
Eccentric wear is serious, vibration aggravation；The reliability of turnover plate type tubing anchor is low；Hydraulic tubing anchor sets and unseals process complexity；Torque
The twisting resistance of anchor is insufficient.Above method there are the problem of make current subsurface progressive cavity anchor that can not meet complicated underground work
Condition requirement constrains screw pump oil production technology and applies and development.
Utility model content
In order to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of screw pump cam-type righting turnover panel
Dual anti-rotating protection is realized in anchor, the generation of oil pipe severe bends phenomenon caused by avoiding pressuring oil pipe, is eliminated vibration, is avoided bar
Column is in direct contact with tube inner wall.
The purpose of this utility model is achieved through the following technical solutions：A kind of screw pump cam-type righting turnover panel
Anchor, including top connection, upper center tube, lower center tube, slips, it is characterized in that：Upper center tube top is equipped with number uniformly distributed in an axial direction
A translating cam face；Centralizer main body is sleeved on top connection lower end, spring socket sleeve on upper center tube and with main righting body
Threaded connection, assemble big spring between the locating piece on spring base and lower center tube；Centralizer body top is equipped with several
Bar hole sets slips in hole, and the arc-shaped lower face of slips is contacted with sliding cam face, and connecting spring bottom is distinguished at the both ends of slips
Seat sets several spring eyes in centralizer main body, is pressed spring on spring pedestal by spring eye, in the righting of spring upper end
Device main body welding gasket；Centralizer lower body part is evenly distributed the several bar-shaped troughs of setting, and setting is with ratchet in half bar-shaped trough
Turnover panel, turnover panel bottom setting leaf spring, setting friction plate in the alternate bar-shaped trough of another half, setting is more below each friction plate
A spring, turnover panel and friction plate both ends are rotatably connected in centralizer main body.
The beneficial effects of the utility model：The generation of oil pipe severe bends phenomenon, realizes caused by avoiding pressuring oil pipe
Dual anti-rotating protection eliminates vibration, and can prevent product soil is too many to influence spring performance.

Shape hole 15, spring eye 16, bar-shaped trough 17, big spring 18, locating part 19, screw thread J.
Specific embodiment
The utility model is described in further detail by 1-5 below in conjunction with the accompanying drawings：
Concrete structure is as follows：Top connection 1 is connected through a screw thread upper center tube 12；12 top of upper center tube is equipped with circumferentially
Four sliding cam faces 7 of cloth；Main body 2 is sleeved on 1 lower end of top connection, and spring base 10 is sleeved on upper center tube 12 and and main body
2 screw thread J connections, upper center tube 12 are connected through a screw thread with lower center tube 13, in spring base 10 with determining on lower center tube 13
Big spring 18 is assembled between the part 19 of position；Centralizer body top is set there are four bar hole 15, setting slips 4,4 circular arc of slips in hole
Shape lower face is contacted with sliding cam face 7, the both ends difference connecting spring pedestal of slips 4, the righting positioned at 15 both ends of bar hole
Several spring eyes 16 in device main body are set, spring 3 are pressed on spring pedestal by spring eye 16, in the centralizer of spring upper end
Main body welding gasket 5, circumferentially arranged several sand discharge holes 11 on the gasket 5 of 15 lower end of bar hole；Centralizer lower body part edge
It is circumferentially uniformly arranged in 6 bar-shaped troughs, 17,3 slots and the turnover panel 14 with ratchet 14-1 is set, turnover panel bottom setting leaf spring 6, another 3
Friction plate 8 in alternate slot is set, the springs 9 of 4 arrangements, 8 both ends of turnover panel 14 and friction plate are set below each friction plate 8
It is rotatably connected in centralizer main body 2, i.e., is limited by gasket 5 and spring base 10.
Operation principle：
1. screw pump cam-type righting turnover panel anchor is anchored：1 upper end of top connection is connected with screw pump lower end, by this practicality
It is novel to transfer to design well depth position, oil pipe is rotated clockwise, screw pump and top connection 1 is driven to rotate clockwise, then band
Dynamic upper center tube 12 rotates clockwise, and slips 4 rotates to D1 relative to sliding cam face 7 by D2, makes slips 4 from 2 bar shaped of main body
In hole 15 in ejection to internal surface of sleeve pipe.Since main body is under the action of turnover panel 14, facing sleeve is static, and upper center tube 12 is relatively main
Body 2 rotates, and slips 4 struts, anchoring string.
2. screw pump cam-type righting turnover panel anchor unseals：Oil pipe is above carried, top connection 1 is driven to move up, then drives upper center
Pipe 12 moves up, and under the effect of spring 3, upper center tube 12 rotates, and slips 4 rotates to D2 relative to cam surface by D1, and slips 4 is received
It returns, completes deblocking.
