Abstract
The utility model relates to a tubular axis eccentricity measuring tape. The tubular axis eccentricity measuring tape comprises a vertical dial plate, a ruler rod and a target plate. A bottom portion of the vertical dial plate is provided with a ruler rod fixing groove. The ruler rod fixing groove is internally provided with the ruler rod. The ruler rod is fixed through a ruler rod fixing nut on the ruler rod fixing groove. The vertical dial plate is connected with a bottom portion of a T-shaped magnet bracket through a rotating shaft. Two ends of a top portion of the T-shaped magnet bracket are respectively provided with magnets. The target plate is fixed on the ruler rod through a target plate moving nut in a bottom portion of the target plate. A pointer is arranged on the T-shaped magnet bracket. A bottom portion of the ruler rod is provided with a gravity pendulum. Two movable scales perpendicular to each other are arranged on the target plate. The tubular axis eccentricity measuring tape has the advantages that the midperpendicular where the center of the hollow tube is positioned is found out through the gravity pendulum, the center of the round tube is determined by using the known hollow tube internal diameter (or the actual measured internal diameter), the design theory tube line axis is made by using a measuring laser guiding beam, and then the deviation from the theory design is measured through target plate data.
Description
Technical field
The utility model relates to the eccentric chi of surveying of a kind of tubular axis.
Background technology
At present in hollow pipeline (diameter is above caliber pipeline more than or equal to 600mm) installation process; often can appear at the pipeline external environment and measure the situation that does not allow measure center; then can't determine whether whether the position of the pipeline axis of actual hollow pipeline exist deviation with theoretic pipeline axis this moment, can't realize that hollow pipeline effectively installs control according to existing design drawing.
The utility model content
The purpose of this utility model provides the eccentric chi of surveying of a kind of tubular axis, find out the perpendicular bisector at place, the hollow pipeline center of circle by the gravity pendulum, and utilize known hollow pipeline internal diameter to determine the center of circle of pipe, recycling is measured the laser guide light beam and is got the design theory pipeline axis, measure deviation with Theoretical Design by the target disc data, to solve present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
The eccentric chi of surveying of a kind of tubular axis, comprise vertical dial plate, bar chi and target disc, described vertical dial plate bottom is provided with bar chi pickup groove, the top of bar chi is fixed in the bar chi pickup groove, the bar chi is fixed by the bar chi hold-down nut on the bar chi pickup groove, vertical dial plate is connected by the bottom of rotating shaft with T shape magnetite support, and T shape magnetite support is provided with pointer, and the two ends that T shape magnetite props up top of the trellis are respectively equipped with magnetite; Described target disc is provided with orthogonal two mobile scales, and target disc is fixed on the bar chi by the target disc travelling nut of its bottom, and described bar chi bottom is provided with the gravity pendulum.
The beneficial effects of the utility model are: the perpendicular bisector of finding out place, the hollow pipeline center of circle by the gravity pendulum, and utilize known hollow pipeline internal diameter (or on-the-spot actual internal diameter that records) to determine the center of circle of pipe, recycling is measured the laser guide light beam and is got the design theory pipeline axis, measures deviation with Theoretical Design by the target disc data.
