Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] Such as Figure 1-Figure 5 As shown, the present invention includes a T-shaped frame 3, clamping grooves are arranged on both sides of the large end of the T-shaped frame 3, and a pair of fixed contacts 1 are respectively limited to the clamping grooves on both sides by a pair of pressure plates 2 and first fixing screws 29. Inside, the adjustment screw 30 adjusts the extension of the fixed contact 1 to reach the calibration position; the prism base 4 is fixed in the corresponding hole in the middle of the small end of the T-shaped frame 3 by the second fixing screw 21, and the prism rod 5 is inserted into the prism base 4, and tightened and fixed by the tension bolt 7 at the lower end.

[0026] The screw hole adapter is installed in the waist-shaped slot on the small end side of the T-shaped frame 3 . The screw hole adapter includes a mandrel 12 , a compression sp...

Abstract

The invention provides a high-precision high-speed railway track board small-jaw measuring frame and a measuring method thereof. The track board small-jaw measuring frame comprises a T-shaped frame, wherein a pair of fixed contacts is arranged on two sides of a big end of the T-shaped frame, a prism table is fixed in a corresponding hole in the middle part of a small end of the T-shaped frame, a screw hole adapter is arranged in a corresponding hole in the end part of the small end of the T-shaped frame, an inner hole of a bushing is matched with an outer cylindrical surface of a shell of the screw hole adapter, an inner hole of a cam is matched with an outer cylindrical surface of the bushing in an embedding manner, the pair of fixed contacts pushes against a support rail surface by utilizing the eccentricity of the cam in the rotation process, and the screw hole adapter, the bushing and the cam form a link mechanism. According to the track board small-jaw measuring frame, a geometric state of a track board is adequately simulated, the location problem in the mile direction is solved, relative reliability in location is achieved by utilizing the screw hole adapter, the installation interference caused by a dimensional error and a position error of a track nail hole can be simultaneously avoided, and the center of a ball prism is located on a transverse central plane of a rail sleeper.

Description

technical field [0001] The invention relates to a high-speed railway track slab fine adjustment device, in particular to a track slab small jaw measuring frame and a measuring method thereof. Background technique [0002] In the fine adjustment operation of CRTS III track slabs of high-speed railways, it is necessary to install measurement auxiliary devices on the track slabs. The traditional auxiliary measurement devices use screw holes or a jaw surface as the reference reference for lateral measurement, and the final lateral limit of the track It is realized by the jaw surface, and the screw hole only provides a downward anchoring force for the fastener. The screw hole is made of plastic. If it is not reasonable as a horizontal measurement reference for the fine adjustment measurement of the track plate, the fine adjustment accuracy will not be achieved. The traditional measuring device that takes the jaw surface as the reference datum for lateral measurement has been gre...
