Detailed description of the invention
In order to make the technical problem to be solved, technical scheme and beneficial effect clearer,
Below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that this place is retouched
The specific embodiment stated only in order to explain the present invention, is not intended to limit the present invention.
The Automatic positioner of pipe column circle center that embodiments of the invention are provided is for measuring all kinds of tubular pillar such as steel
The center of circle of tubing string.Refer to Fig. 1 to Fig. 3, this Automatic positioner of pipe column circle center includes first connecting rod 110, sets
Put the second connecting rod that the spring 130 at first connecting rod 110 two ends, the respectively other end with spring 130 are connected
150, the pulley 170 that is rotatably assorted with second connecting rod 150 free end respectively and be connected to first connecting rod 110
On ball 190.Head rod 110, spring 130 and the second connecting rod 150 are arranged in a linear；First
Connecting rod 110, spring the 130, second connecting rod 150 and pulley 170 are arranged axisymmetricly.Ball 190
It is connected on first connecting rod 110 by being perpendicular to the connector 192 of first connecting rod 110, and connector 192
It is positioned on the symmetry axis of Automatic positioner of pipe column circle center with the tie point of head rod 110.At the present embodiment
In, connector 192 is rigid arm, and certainly, in other embodiments, connector can also be flexible company
Wiring or connection rope.
Spring 130 be elastic force identical and have enough elastic force compression spring or compression shell fragment, it is ensured that pulley 170
Force of sliding friction with pipe string internal wall is more than the gravity of Automatic positioner of pipe column circle center self, it is to avoid the tubing string center of circle
Autonavigator slides along column axis direction under gravity.
The free end of second connecting rod 150 passes the center of pulley 170 after vertically bending, make pulley 170 to turn
It is fixed on the free end of second connecting rod 150, the rotational plane of pulley 170 and tubing string Arc Center Probe dynamicly
The symmetry axis of device is vertical.It is combined together by the way of riveting between pulley 170 and second connecting rod 150,
Or can also be combined together by the way of screw lock, as long as ensureing rotational plane and the tubing string of pulley 170
The symmetry axis of Arc Center Probe device is vertical and pulley 170 can be rotated i.e. at the free end of second connecting rod 150
Can.The outer most edge of pulley 170 is curved, to reduce the resistance that pulley 170 rolls on tubular pillar inwall.
Additionally, the outer most edge of pulley 170 also lays some parallel grooves along pulley circumference, to reduce pulley further
170 resistances rolled on tubular pillar inwall.
During use, only this Automatic positioner of pipe column circle center need to be placed in tubular pillar, at spring 130 elastic force
Under effect, pulley 170 producing a component forward or backward, band movable pulley 170 rolls, and bullet
Spring 130 makes the force of sliding friction between pulley 170 and steel pipe column inwall increase to the pressure of pulley 170,
Instrument is avoided to drop.When the pressure that pulley 170 bears is equal with spring 130 elastic force, pulley 170 stops
Rolling, the pressure potential of pulley 170 will be on same straight line by tubular pillar inwall with the elastic force of spring 130,
And this straight line is i.e. at one of tubular pillar diametrically, when head rod 110 is static, two springs 130
Between elastic force also reach balance, therefore the ball 190 being in locator center is the position, the center of circle of this steel pipe column
Put.
Use technical scheme, at least have the advantage that this Automatic positioner of pipe column circle center has
It is automatically positioned feature, only this instrument need to be placed in tubular pillar, when device to be positioned is in transfixion, ball
Position be tubular pillar home position, need not manually operate, and this Automatic positioner of pipe column circle center
Do not limited by tubular pillar sectional dimension, be applicable to various round tubes column section, it is seen that this locator is used peace
Complete convenient, certainty of measurement height.Additionally, this Automatic positioner of pipe column circle center simple in construction, it is simple to deposit.
The upper described presently preferred embodiments of the present invention that is only, not in order to limit the present invention, all in the present invention
Spirit and principle within any amendment, equivalent and the improvement etc. made, should be included in the present invention's
Within protection domain.
