Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The tubing string Arc Center Probe device that embodiments of the invention provide is for measuring for example center of circle of steel pipe column of all kinds of tubular pillars.Please refer to Fig. 1 to Fig. 3, the second connecting rod 150 that this tubing string Arc Center Probe device comprises first connecting rod 110, be arranged on the spring 130 at first connecting rod 110 two ends, be connected with the other end of spring 130 respectively, the pulley 170 being rotatably assorted with second connecting rod 150 free ends respectively and be connected to the ball 190 on first connecting rod 110.Head rod 110, spring 130 and the second connecting link 150 are arranged in a linear; First connecting rod 110, spring 130, the second connecting link 150 and pulley 170 arrange axisymmetricly.Ball 190 is connected on first connecting rod 110 by the web member 192 perpendicular to first connecting rod 110, and web member 192 is positioned on the axis of symmetry of tubing string Arc Center Probe device with the tie point of head rod 110.In the present embodiment, web member 192 is rigid arm, and certainly, in other embodiments, web member can be also flexible connection line or connection cord.
Spring 130 is for elastic force is identical and have Compress Spring or the compression shell fragment of enough elastic force, guarantee that pulley 170 and the force of sliding friction of pipe string internal wall are greater than the gravity of tubing string Arc Center Probe device self, avoid tubing string Arc Center Probe device along tubing string axis direction, to slide under Action of Gravity Field.
After the vertical bending of free end of second connecting rod 150, through pulley 170 center, make pulley 170 be rotatably mounted to the free end of second connecting rod 150, the rotational plane of pulley 170 is vertical with the axis of symmetry of tubing string Arc Center Probe device.Mode by riveted joint between pulley 170 and second connecting rod 150 is combined together, or can also be combined together by the mode of screw lock, as long as the assurance rotational plane of pulley 170 and the axis of symmetry of tubing string Arc Center Probe device are vertical and allow pulley 170 rotate at the free end of second connecting rod 150.The outer most edge of pulley 170 is curved, the resistance rolling on tubular pillar inwall to reduce pulley 170.In addition, the outer most edge of pulley 170 is also circumferentially laid some parallel grooves, the resistance rolling on tubular pillar inwall further to reduce pulley 170 along pulley.
During use, only need this tubing string Arc Center Probe device to be placed in tubular pillar, under the effect of spring 130 elastic force, pulley 170 is produced to a component forward or backward, band travelling block 170 rolls, and spring 130 increases the force of sliding friction between pulley 170 and steel pipe column inwall to the pressure of pulley 170, avoid instrument to drop.When the pressure bearing at pulley 170 equates with spring 130 elastic force, pulley 170 stops rolling, tubular pillar inwall will be with the elastic force of spring 130 on same straight line to the pressure potential of pulley 170, and this straight line is on a diameter of tubular pillar, when head rod 110 is static, elastic force between two springs 130 also reaches balance, therefore the i.e. home position of steel pipe column for this reason of the ball 190 in steady arm center.
Adopt technical scheme of the present invention, at least have the following advantages: this tubing string Arc Center Probe utensil has automatic location feature, only this instrument need be placed in tubular pillar, device to be positioned is when transfixion, the position of ball is tubular pillar home position, need not manually operate, and this tubing string Arc Center Probe device is not subject to the restriction of tubular pillar sectional dimension, applicable to various round tubes column section, this steady arm is safe and convenient to use as seen, measuring accuracy is high.In addition, this tubing string Arc Center Probe device is simple in structure, is convenient to deposit.
The above is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
