Measuring device and control method applicable to evacuation platforms in subway tunnels

Abstract

The invention belongs to the engineering technological science, mainly relates to limit control on construction for evacuation platforms in urban trail transit, and particularly discloses a measuring device and a control method for heights, widths and inner and outer edge lines of evacuation platforms. The measuring device is characterized in that a group of single-sided wheel flanges are arranged at the bottom of the right side of a stereoscopic rectangular cabinet frame, a group of double-sided wheel flanges are arranged at the bottom of the left side of the cabinet frame, three vertical beams are arranged on the cabinet frame, a crossbeam scale which is controlled via a first adjusting bolt and a second adjusting bolt is arranged on a groove of the first vertical beam and a groove of the second vertical beam, an extending block with a strut is erected on a front section of the upper portion of the left surface of the cabinet frame and is positioned on the lower portion of the crossbeam scale, a laser marking instrument platform is arranged in an inner cavity of the left portion of the cabinet frame, vertical adjusting bolts are arranged at four corners of the laser marking instrument platform, a reserved hole is formed in the center of the laser marking instrument platform, and a tool box is arranged on the right surface of the cabinet frame. The measuring device and the control method have the advantages that measurement and control data of the measuring device can be read visually and quickly, the measurement accuracy is high, operation is simple, and requirements on limit and line appearance quality of the evacuation platforms are met.

Description

[technical field] [0001] The invention belongs to the science of engineering technology, and mainly relates to the boundary control of evacuation platform construction in urban rail transit, specifically including a measuring device and control method for the height, width, and inner and outer edges of the evacuation platform. [Background technique] [0002] Urban rail transit is an important part of urban public transportation. With the development of the national economy and the acceleration of urbanization, the development of rail transit is also accelerating. The popularity of evacuation platforms in rail transit is also increasing. Domestic Guangzhou, Tianjin, Suzhou, Hangzhou and other subway tunnels have begun to set up evacuation platforms in interval tunnels to overcome the slow travel speed of passengers or workers on the track bed during accidents. And prone to dangerous disadvantages. During the construction of the Guangzhou Metro, a linear motor induction plate...
