Abstract

The embodiment of the invention provides an application method of a track retesting frame. The method comprises the following steps: placing the track retesting frame on a track bearing surface of a sleeper to be tested, so that a positioning surface of the track retesting frame is attached to the track bearing surface, and covering of fasteners of the sleeper to be tested by the track retesting frame is avoided; adjusting a tensioning mechanism and a positioning mechanism to enable the height between the center of a prism and a positioning surface to be within a first preset range; adjustingthe deviation between the center of the prism and the center of a track bearing groove of the sleeper to be measured to be within a second preset range; and measuring a midpoint of the sleeper to be measured , and obtaining the track center position where the track is installed in the track bearing groove. According to the application method of the track retesting frame, the track retesting framecan be directly placed on the track bearing groove provided with a fastener system, the retesting precision requirement is met, the fastener disassembling and assembling cost can be saved, and the retesting efficiency is improved.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a method for using a track retesting frame. Background technique [0002] With the development of high-speed rail technology, high-speed rail construction has entered the era of informatization and refined management. With the application of big data, the construction of CRTS double-block ballastless track has retesting procedures one by one, which can not only guide the construction on site, but also provide Subsequent construction saves costs. Therefore, this process has entered the sequence of information management, accepted by the majority of construction units, and is ready to be widely promoted. At present, the sleeper-by-sleeper re-measurement mainly adopts the self-centering measurement frame based on the positioning of small jaws. The use of this type of frame requires no objects on the groove surface of the rail to ensure that the positioning surface of the frame ...
