As shown in fig. 3, the embodiment of the present invention further provides a method for rail detection of a straddle type monorail, where the method is used for the rail detection device, and specifically includes:
installing a total station in the extending direction of the monorail, adjusting the three prism rods to the same height, arranging a prism forward direction total station, placing a track traveling device with a triple prism at one end of the monorail beam, and ensuring that the total station and the prism have good sight lines for reading data of the three prisms in real time;
and moving the traveling rail device, recording the central coordinates of the three prisms by the total station, combining the three coordinates with the elevation scales of the corresponding prisms, further calculating three coordinate points corresponding to the traveling rail surface, and comparing and analyzing the three coordinate points with the designed value to detect the linear precision of the single rail.
The features of this study and other related features are described in further detail below by way of example for the purpose of understanding by those of ordinary skill in the art:
before the measurement of the monorail beam, a running gear 13 is placed at one end of the monorail beam 11 and a total station 12 is erected at a distance from the beam end in a direction extending longitudinally along the beam. And then three prisms 10 are respectively installed and fixed on the three prism rods for connection, the prisms longitudinally face the total station 12 along the beam, the three prism rods must be adjusted to the same height before measurement, and meanwhile, the sight line from the total station 12 to each prism 10 is ensured not to be shielded. Since the device 13 moves to different positions of the monorail beam 11 during measurement, the arrangement ensures that the prism 10 is always directed to the total station 12 during the whole measurement process.
Assuming that the total station 12 is erected at the right end of the monorail beam 11 in the extending direction as shown in fig. 2, the track device 13 can be pushed from the left end to the right end of the monorail beam 11, or from the right end to the left end of the monorail beam 11, but the starting point and the ending point should be the contact points of the corresponding rear and front track wheels 8 and the monorail beam 11 at the beam end, so as to ensure that the measuring range covers the whole monorail beam 11.
Each time the tracking device 13 is pushed to a position, the observer records the readings of the prism 10 with the total station 12, and records the corresponding position coordinates and scale values of the prism rods 1, 2, 3. The measuring point position and the measuring times of the track device 13 during the crossing are determined according to the length of the monorail beam 11 and the fine requirement of measurement.
The scale value of the prism rod represents the distance h between the center point of the corresponding prism 10 and the bottom of the rail wheel 8, the recorded coordinates of the three prisms can form a plane, the normal unit vector of the plane is calculated, then the normal vector with the mode of h is obtained, and the coordinates of the measuring point of the walking surface can be converted by combining the original three coordinates. Furthermore, the three-dimensional coordinates of all points of the track beam can be obtained according to the shape of the beam body, and then the three-dimensional coordinates are compared with the design value.
A rail detection method for a straddle type monorail comprises the steps that three prism rod groups are adjusted to be equal in height, a rail travelling device with three prisms is placed at one end of a monorail beam, a total station is installed in the extending direction of the monorail, and the total station and the three prisms are adjusted to be not shielded in sight and used for reading data of the three prisms in real time;
