Accurate adjusting frame of high-speed railway ballastless track plate

Abstract

The invention provides an accurate adjusting frame of a high-speed railway ballastless track plate, which is convenient, accurate and stable to mount, has high precision, and is used for accurate adjusting work of CRTS II and CRTS III ballastless track plates of a high-speed railway. The accurate adjusting frame comprises a rack (1); a pair of through holes (5) is arranged on the rack (1); a connecting line of the centers of the through holes (5) is parallel to the straight-line long edge of the rack (1); bearings (2) are mounted at the two ends of a shaft (3) and are clamped by a clamping spring (4); the shaft (3) is provided with one pair of through holes and is mounted on the rack (1) through a screw rod (6) and the through holes (5); a positioning rod (10) is mounted on the through holes of the rack (1) through a nut (8); a magnet (9) is mounted at the top of the positioning rod (10) and is used for mounting a measuring ball; and the through holes (7) on the rack (1) are used for guaranteeing the vertical placing precision of the frame. According to the accurate adjusting frame of the high-speed railway ballastless track plate, the precise machining precision is controlled so that the rack (1) is horizontal; the vertical distance from the center of the positioning rod (10) to the straight-line long edge of the rack (1) is a fixed value; and after the measuring ball is mounted at the top of the positioning rod, the distance from the spherical center of the measuring ball to the supporting point of the positioning rod (10) is a fixed value. The frame disclosed by the invention has the advantages of small and light frame, convenience and accuracy for installation, good stability, high precision, small influences caused by a temperature and convenience for storage and transportation.

Description

technical field [0001] The invention relates to a high-speed railway ballastless track slab fine-adjustment measurement frame, in particular to CRTS II and CRTS III track slab fine-adjustment measurement frames. Background technique [0002] China's railway construction has entered a stage of rapid development of high-speed railways. China's high-speed railways have undergone processes of introduction, absorption, improvement, and innovation. At present, design, construction, trains, locomotives, and signal systems are all intellectual property rights. In the future, China's high-speed rail technology , equipment, construction, etc. will go abroad. Generally, the railway with a train running speed of more than 250 km / h is called a high-speed railway. If the original ballasted track is used, gravel will be rolled up when the train runs at high speed, so the ballastless track is used, and the ballastless track is divided into two blocks. Ballastless track and slab ballastless...
