Abstract
The utility model discloses a kind of spring erection device, including top connection, lower contact, supporting positive cover, spring base, multi-directional ball and air spring, and multi-diameter shaft of the supporting positive cover along top connection loads, and supporting positive cover is annular body structure, and annular body uniformly opens up blind round hole；Spring base is installed on by screw in the blind hole of the supporting positive cover, and multi-directional ball mounts elastically portion, and air spring is arranged between supporting positive cover and lower contact.The utility model can pass through the irregular duct section of bore, moreover it is possible to reduce the friction that centralizer is gone between duct wall, reduce the radial and axial impulsive force that centralizer is subject to.
Description
Technical field
The present invention relates to a kind of oil, natural gas fishing operation field, more particularly to a kind of underground fishing tool is helped
Equipment.
Background technology
The centralizer of fishing tool in the wellbore is the important factor of success processing salvaging accident, and matched
Centralizer is one of visual plant for ensureing that fishing tool is placed in the middle.The existing roller either with axial direction or radial direction roller shaft is helped
Positive device, its roller shaft are affixed on centralizer, although can reduce friction resistance in handling fishing tool to a certain degree
Power, but when hole diameter is irregular, pair roller causes larger impulsive force with roller shaft, has a strong impact on the centralizer life-span, particularly
When centralizer run to salvage accident pipeline section, because accident may cause hole diameter to deform, the existing easy jam of centralizer, make
Into secondary salvaging accident.
Utility model content
Purpose of utility model：In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of spring base
Formula centralizer, for ensureing erection device of the fishing tool by irregular hole diameter.
Technical scheme：In order to realize above-mentioned purpose of utility model, the technical solution adopted in the utility model is as follows：
A kind of spring erection device, including top connection, lower contact, supporting positive cover, spring base, multi-directional ball and air spring,
Multi-diameter shaft of the supporting positive cover along the top connection loads, and supporting positive cover is annular body structure, and annular ring body uniformly opens up
Blind round hole；Spring base is installed on by screw in the blind hole of the supporting positive cover, and the multi-directional ball mounts elastically portion, institute
Air spring is stated to be arranged between supporting positive cover and lower contact.
Preferably, the top connection is multi-diameter shaft, one end is set to external thread structure, and the other end is set to external screw thread, middle
It is set to central through hole；The lower contact is cylindric, and one end is provided with external screw thread, and the other end is set to internal thread, and centre is set to center
Through hole；Sealing ring is additionally provided among the supporting positive cover and top connection.
Preferably, the supporting positive cover is axially being uniformly provided with 4 blind round hole, 8 circles are uniformly provided with circumferencial direction
Shape blind hole.
Preferably, the spring base is bolted with multi-directional ball.
Preferably, sealing ring is rubber seal, air spring is rubber air spring.
Beneficial effect：Compared with prior art, the utility model has advantages below：
The utility model employs spring base, and centralizer can be made to pass through the irregular salvaging pipeline section of bore；In bullet
Spring is taken to be rolled flexible provided with multi-directional ball, multi-directional ball, it is possible to reduce friction during decentralization between centralizer and duct wall；Multi-directional ball
It is bolted, can removes and installs with spring base so that multi-directional ball easy to wear is changed convenient；Spring base can be reduced and helped
Radial impact force suffered by positive device, the rubber air spring between spring base and lower contact can be not only reduced suffered by centralizer
To axial impact force can also play sealing function.
