Abstract

The invention discloses a rail thermite welding joint protective treatment device. The rail thermite welding joint protective treatment device comprises a cutoff treatment trolley. The cutoff treatment trolley is internally provided with a left-right through cutoff chamber with an upward opening. A cooling chamber communicates with the cutoff chamber. A welding joint iron plate cutoff device in bilateral symmetry is arranged on the cutoff treatment trolley. The welding joint iron plate cutoff device is used for cutting off a high-temperature steel plate formed after rail thermite welding. A lifting supporting device located on the lower side of the welding joint iron plate cutoff device is arranged on the cutoff treatment trolley. The welding joint iron plate cutoff device is internally provided with vibration cutoff devices in bilateral symmetry. The cutoff chamber is internally provided with an iron plate push and storage device located on the front side of the welding joint iron plate cutoff device. The rail thermite welding joint protective treatment device can be used for directly cutting an I-shaped mechanism of a rail and reduces the later-period welding joint grinding treatment difficulty and the workload. Moreover, the machining process is located in a fully-sealed space, and workers are protected against scalding.

Description

technical field [0001] The invention relates to the technical field of rail welding protective treatment, in particular to a protective treatment device for rail aluminothermic welding. Background technique [0002] The on-site welding of rails usually uses the aluminothermic reaction for welding. After the aluminothermic reaction is completed, a high-temperature iron plate will be formed at the welding place. After that, the worker needs to manually install the hydraulic shearing machine on the track to cut the high-temperature iron plate. The cutting process is high temperature. The iron plate is directly exposed to the outside, and there is a risk of scalding personnel. Since the hydraulic shearing machine cannot directly cut out the I-shaped mechanism of the rail, it is necessary for the worker to hammer the high-temperature iron plate with a hammer for further processing after the hydraulic shearing machine completes the cutting. processing, so that the efficiency of th...
