Abstract

The invention discloses a protective treatment device for the aluminothermic welding of rails, which includes a shearing treatment trolley, which is provided with a left and right through and upward shearing cavity, and the cooling cavity communicates with the shearing cavity. The shearing treatment trolley is provided with a left-right symmetrical iron plate shearing device at the welding point, and the iron plate shearing device at the welding position is used for cutting the high-temperature steel plates formed after the aluminothermic welding of the rails. The shearing treatment trolley is equipped with The lifting support device located on the lower side of the iron plate shearing device at the welding place, the left and right symmetrical vibration cutting device is installed in the iron plate shearing device at the welding place, and the iron plate shearing device at the welding place is installed in the shearing chamber The iron plate push storage device on the front side, the invention can directly cut out the I-shaped mechanism of the rail, which reduces the difficulty and workload of grinding the welding place in the later stage, and the processing process is located in a fully sealed space to avoid the risk of personnel being burned.

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...
