Steel rail surface jacking device

Abstract

The invention relates to the technical field of track detection, in particular to a steel rail surface jacking device. The steel rail surface jacking device comprises a guide rod 1, a sleeve 2, a gear 3, a rack 4, a spring 5, a handle 6, a steel rail 7, a side beam 8, a guide wheel 9, a guide wheel 10 and a sliding block 11; the guide wheel 9 is arranged on the steel rail, the side beam is arranged on the guide wheel 9, the guide wheel 10 is installed below the side beam, the sleeve 2 is arranged on the guide rod 1, the rack 4 is arranged beside the sleeve 2, and the gear 3 is used in cooperation with the rack 4. The spring is arranged on the outer side of the sleeve 2, and the handle 6 is connected to the gear 3.

Description

technical field [0001] The present invention is a research on the rail surface of the left rail for rail detection: when the rail inspection trolley is walking on the rail, a spring tightening device is used to realize the effect of being tightly attached to the inner rim of the left rail. Background technique [0002] With the development of high-speed and heavy-duty railways, various problems occur when the rails are running-in with the wheel sets during use, such as corrugation, polygons, and contact spots. In order to solve the above problems and extend the service life of the rails, it is necessary to The rail surface is inspected, but during the inspection process, the laid rail is not horizontal, so the guide wheel cannot cling to the rail surface when walking, and the rail inspection trolley moves left and right on the rail, resulting in insufficient stability of the inspection data. At the same time, when the track inspection trolley passes through the gaps between ...

Problems solved by technology

[0002] With the development of high-speed and heavy-duty railways, various problems occur when the rails are running-in with the wheel sets during use, such as corrugation, polygons, and contact spots. In order to solve the above problems and extend the service life of the rails, it is necessary to The rail surface is inspected, but during the inspection process, since the laid rail is not horizontal, the guide wheel cannot cling to the rail surface when walking, and the rail inspection trolley moves left and right on the rail, resulting in insufficient stability of the inspection data

At the same time, when the track inspection trolley passes through the gaps between (1) rails and guard rails, (2) rails and switch rails, and (3) turnout tips, the traditionally designed device passes through these gaps, and the guide wheels are easy to get stuck in the gaps; however , if you choose to use manual measurement instead of using detection devices, not only the efficiency is low, the workload is heavy, the workers are hard, but the quality of the measurement data is not enough and there are errors
