Answer the body of various different-diameters.
Description of the drawings
Fig. 1 is the schematic diagram that the centralizer reducing of the present invention adjusts to major diameter pipe well the state that detects.
Fig. 2 is the schematic diagram that the centralizer reducing of the present invention adjusts to minimum diameter pipe well the state that detects.
Specific embodiment
Below in conjunction with the accompanying drawings technical scheme is elaborated.
As described in Figure 1, a kind of reducing integration centralizer of the invention, including Instrument shell 1 and setting and instrument shell
Body upper shell erection device, housing erection device include fixed cover 3, reducing adjusting means and at least one pair of be symmetricly set in instrument
The righting arm of the reducing of device housing both sides；The righting arm of reducing is articulated and connected and is formed by upper pendulum bar 41 and draft link 42；On
Fork 41 is connected with fixed cover 3, and fixed cover 3 is spacing by limited block 2, and draft link 42 is connected with reducing adjusting means, and reducing is adjusted
Regulating device is mobile on Instrument shell 1 to control angle between upper pendulum bar 41 and draft link 42, and upper pendulum bar 41 and draft link 42 are hinged
Place is provided with roller A5, and roller A5 is pressed on tube wall to be detected, is provided with roller B6, reducing adjusting means at the top of draft link 42
Including reducing adjusting set 9 and the slip cap being set in reducing adjusting set 97 and spring 8, reducing adjusting set 9 can be in instrument shell
Move and be fixed on Instrument shell by holding screw on body 1；Slip cap 7 can be moved in reducing adjusting set 9, slip cap
7 one end is connected with draft link 42, one end of other end connecting spring 8；The other end of spring 8 is fixedly mounted on reducing adjusting set
On 9.
The centralizer of the present invention need not change righting arm for the body of different-diameter before detection, be adjusted by reducing, first
Holding screw in reducing adjusting set 9 is unclamped first, now reducing adjusting set 9 freely can be slided on Instrument shell, change righting
The angle of the upper pendulum bar 41 and draft link 42 of arm so that righting arm opens or shrinks, makes peak on the outside of 4 roller A form circle
Diameter slightly larger than workpiece body to be checked 11 internal diameter, the holding screw in reducing adjusting set is tightened, you can to the diameter
Body is detected, convenient and swift, need not be changed centralizer arm and be carried standby redundancy.
The spring 8 and slip cap 7 of the present invention is arranged in reducing adjusting set 9, and spring 8 has initial pressure when mounted,
During detection, as on the outside of 4 roller A, peak forms internal diameter of the diameter of a circle slightly larger than workpiece body to be checked 11, when detection dress
It is placed in workpiece for measurement body, inner-walls of duct extruding righting arm, righting arm open, and draft link promotes slip cap, slip cap to receive
Slide in reducing adjusting set 9 after power, extrusion spring 8, roller A5 produce outside component, pressure in the presence of 8 elastic force of spring
On the inwall of workpiece body to be checked 11, so as to reach righting effect.In the present invention, fixed cover 3 passes through 4 righting arms and cunning
Dynamic set 7 connects, and 4 righting arms are uniformly distributed in the surrounding of Instrument shell 1.
Centralizer in the present invention, generally requires 2-3 erection device, be respectively arranged on Instrument shell it is upper, in,
Lower three positions, it is ensured that instrument stabilizer works, and during detection, the four rolling A5 of erection device is contacted with inboard wall of tube body, makes detection
Rolling frictional resistance is only existed between instrument and body, makes detection resistance minimum；When pipe joint groove or step, it is arranged on
Roller B on righting arm draft link is acted on body, can effectively be prevented roller A from falling into groove or blocking step and be caused instrumentation card
Phenomenon.
Embodiment described above is only that the preferred embodiment of the present invention is described, the not design to the present invention
It is defined with scope, on the premise of without departing from design concept of the present invention, in this area, ordinary skill technical staff is to this
