Embodiment

[0041] The length of the crane track in the first-phase machine repair workshop of a nuclear power plant is 102m, the span is 22.50m, and the track is installed on the crane beam with an elevation of +7.100m.

[0042] see Figure 1-2 , the present invention applies a kind of non-fixed measuring station method track position checking method, comprises the following steps:

[0043] Step 1: Set up the total station station, set up the total station at the ground position in the middle of the truss car track, and be able to see the positions of each detection point;

[0044] Step 2: track start point and end point measurement, measure the coordinates of the track start point and end point on one side. In this embodiment, the coordinates of the start point 2 are (7166.2459, 3014.4692), and the coordinates of the end point 3 are (7261.8414, 3051.4523);

[0045] Step 3: Calculate the azimuth angle. Calculate the azimuth angle of the starting point and the ending point according to t...

Abstract

The present invention relates to the technical field of civil construction, and provides a non-fixed measuring station truss vehicle track position checking method. The method comprises following steps: setting a station of a total station, measuring coordinates of a starting point and an end point of a track, calculating azimuth angle of the starting point and the ending point, rotating azimuth angle of the total station to the azimuth angle of the starting point and the ending point, setting the azimuth angle of the total station to zero, measuring three-dimensional coordinates of each detection point, calculating measured span, and comparing the measured span value with a theoretical span value to obtain a deviation value. In the process of checking track position, the method can set upthe total station according to actual situations of a scene and checking elements, to adapt to the actual situation of a construction site, the method can indirectly display mutual relationship between tracks, visually display the span value between the tracks, has simple operation, reliable data, greatly improves safety of checking on the position and the span, and helps to meet the need of quality control of the on-site construction.

Description

[0001] Technical field: [0002] The invention belongs to the technical field of civil construction, and in particular relates to a method for checking the track position of a truss vehicle at a non-fixed measuring station. [0003] Background technique: [0004] After the crane track of the industrial plant is installed, the span between the tracks should be checked; when the crane has been running for a period of time, in order to know the span of the crane track in time, the span should also be checked to prevent the crane wheel from Therefore, there is a need for a track position inspection method, which can reflect the relationship between the crane tracks in a timely and reliable manner, and provide first-hand information for the maintenance and maintenance of the crane. [0005] At present, the span inspection of the crane track usually uses the method of steel ruler and tension to directly measure the span length. The method is simple in theory and easy to operate. It ...
