Alignment measurement method and device for straddle-type monorail transit lines

Abstract

The present invention discloses a straddle type monorail transit line linear measurement method, comprising the steps: step S1, arranging a flat measurement block on the side, having the higher surface, of a joint plate on a beam end walking face of a track beam, an inclined measurement block having a slope is arranged on the side, having the lower surface, of the joint plate, making the slope face to the flat measurement block, and arranging a frame level on the flat measurement block and the inclined measurement block simultaneously; step S2, adjusting the relative positions of the inclined measurement block and the flat measurement block, to make the frame level to be at the level state; and step S3, obtaining the height differences between the contact positions of the frame level and the flat measurement block as well as the flat measurement block and a contact plate. The straddle type monorail transit line linear measurement method adopts the way of combining the frame level and the two measurement blocks and has the advantage that no professional measurement technical personnel are needed, the accuracy measured by the frame level is higher, the measurement tool is portable, convenient to operate and safe to use, and the detection efficiency is high. The present invention also discloses a measurement device used for implementing the measurement method.

Description

technical field [0001] The invention relates to the technical field of track beam manufacturing, more specifically, to a method for measuring the alignment of a straddle-type monorail transit line. In addition, the present invention also relates to a straddle-type monorail line alignment measuring device for realizing the above-mentioned measuring method. Background technique [0002] Straddle-type monorail traffic lines run rubber-tyred trains, and the track of the running line is a high-precision post-tensioned prestressed reinforced concrete beam prefabricated in the factory, referred to as PC track beam. The section of the PC track beam is I-shaped. Usually, the beam body is 0.85m wide and 1.5m high. Together with the cast steel tension support, the beam height is 2m in total. The maximum beam length is 24m, and the maximum beam body weight is about 65t. The top surface and both sides of the beam body are vehicle running surfaces, the top surface of the beam body is the...

Problems solved by technology

[0005] In the prior art, for the detection of the superelevation value or horizontal error value of the installation cross slope of the track beam, a tower ruler level is usually used, and the measuring instrument must be supported by a professional technician during the detection; due to the narrow track surface, the measuring instrument must be repeatedly supported At the same time, the measurement of the tower ruler level is affected by many environmental factors, and the measurement accuracy is relatively low.
