Abstract

The invention relates to the technical field of rail traffic, and discloses a railway turnout switch machine which comprises a stock rail, sleepers are fixedly connected to the back face of the stock rail, a turnout switch rail is movably connected to one side of the stock rail, a hydraulic machine is fixedly installed on one side of the turnout switch rail, and a hydraulic cylinder is fixedly connected to one side of the hydraulic machine. One side of the hydraulic cylinder is movably connected with an actuating rod, one end of the actuating rod is fixedly connected with an induction coil, an outer ring of the induction coil is movably connected with an induction magnet, one side of the induction coil is fixedly connected with a fan, the other end of the actuating rod is fixedly provided with an electric heating block, and the two sides of the electric heating block are fixedly connected with air blowing openings. The force of pushing the actuating rod to move by the hydraulic machine is utilized to enable the induction magnet to quickly rotate in the moving process, so that induction current is generated to enable the electric heating block to heat, and ice covered on a guide rail is melted.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a railway switch switch machine. Background technique [0002] The switch machine refers to the important signal infrastructure equipment used to reliably change the position of the turnout, change the opening direction of the turnout, lock the tip rail of the turnout, and reflect the position of the turnout. It can well ensure driving safety, improve transportation efficiency, and improve the safety of driving personnel labor intensity. [0003] However, there are still some deficiencies in the use of the switch machine. In the cold season in the north, ice blocks are produced on the rails due to the severe cold, so that the point of the turnout rail and the basic rail do not reach the specified degree of closeness, and the switching process of the turnout cannot be completed. The vibration of the train passing through will cause unlocking and displacement, and safety acci...
