High precision engineering survey setting out method

Abstract

The invention discloses a high-precision engineering measurement lofting discharge device and method. An X-direction guide rail of the device is arranged in a lofting frame, a Y-direction guide rail is arranged on the X-direction guide rail, a target seat provided with an internal thread is arranged on the Y-direction guide rail, a lofting device is arranged on the target seat through threads, X-direction horizontal bubbles and Y-direction horizontal bubbles are arranged on the top surface of a lofting frame respectively, and elevation adjusting bolts are arranged at four corners of the lofting frame respectively. According to the method, the lofting frame is placed in an area needing a lofting point and is adjusted to a horizontal position; the target ball is placed on the target seat, and the plane coordinates of the target ball are measured and the distance between the target ball and the lofting point is calculated through a laser tracker or a total station; the target ball is moved to the lofting point and is fixed, a lofting device is used for replacing the target seat to implement discharge operation. The device and the method can be used for high-precision lofting discharge of production field engineering measurement, so that the defects of a traditional measurement mode are overcome, the measurement precision is guaranteed, the measurement efficiency is effectively improved, the measurement workload is reduced, and the cost of equipment maintenance and overhaul is reduced.

Description

technical field [0001] The invention relates to a high-precision engineering measurement stakeout method. Background technique [0002] When using laser tracker, total station and other optical measuring equipment for high-precision engineering measurement and placement, the ball target is usually placed at the placement point, and the ball target is adjusted in two directions according to the measurement data to adjust to the target position Finally, the target ball is taken out, and the point operation is carried out at the approximate position where the target ball is placed. In this method, firstly, when the ball target moves in two directions, due to the ambiguity of the moving distance, the phenomenon of repeated movement will occur many times, which reduces the efficiency of the stakeout operation. The target ball is removed, and the point is placed at the approximate position of the ball target, which greatly reduces the accuracy of the point setting operation. The...

Problems solved by technology

Therefore, using the traditional method of setting out and setting out points, even if high-precision laser trackers, high-precision total stations and other equipment are used, the measurement efficiency of setting out points on site is low, the measurement time is long, and the measurement accuracy is poor, which affects the production site engineering stakeout. A little work efficiency
