Abstract

This invention is a guided wheel that can avoid the rail edge. The wheel's outside is cone-shaped so that it can dodge the rail edge. When the invention is fixed in the rail-testing car, it can ensure the car to run smoothly and without effect. Therefore, the stability of the car and the accuracy of the testing value will be guaranteed.

Description

technical field [0001] The invention relates to a guide wheel on a rail inspection trolley, in particular to a guide wheel of the rail inspection trolley. Background technique [0002] The rail is under the heavy pressure of the train, and the upper side of the rail is extruded and protruded, forming what is often called "flash". The flash causes the inner side of the rail to be uneven. The rail inspection trolley runs along the rail, and the walking mechanisms at both ends are equipped with guide wheels to move forward along the side of the rail. The shape of the current guide wheel is cylindrical, and the cylindrical surface is in contact with the inner side of the rail to move forward, and the flash of the rail will cause the cylindrical guide wheel to be easily blocked when it runs on the rail. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a guide wheel for a rail inspection trolley. [0004] The invention is realized in this wa...
