Abstract

The invention discloses automatic grinding equipment for a rail welding position. Rail, a power platform is arranged on the upper side of the rail; two mounting and fixing devices which are symmetrical front and back are arranged on the end surface of the lower side of the power platform; the mounting and fixing device is used for mounting and fixing the equipment on a rail; a power device is arranged on the power platform; the power device is used for providing left-right reciprocating motion for polishing the upper side end surface of the rail; the power platform is provided with a reciprocating motion device located on the upper side of the power device. The reciprocating device is used for providing front-back reciprocating motion for polishing the end faces of the left side and the right side of the rail, and the power device and the reciprocating device are provided with three grinding devices in total, so that the rail welding position can be automatically polished, manual auxiliary operation is not needed in the polishing process, and the polishing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of grinding rail welds, in particular to automatic grinding equipment for rail welds. Background technique [0002] Welded long rail refers to a long rail of a certain length that is welded with 25m standard soft welding without drilling joint bolt holes at the rail end and without quenching. Usually, contact welding, air pressure welding and other welding methods are used in the welding rail factory to weld the long rails of 125-500m first, and after the full-length quenching heat treatment, they are transported to the track laying site by special rail trains, and then use aluminum heat flats or small air pressure welding machines. The welding is connected to the design length. After the welding of the rail on the site is completed, the rail welding is usually ground. The current grinding equipment needs to be manually driven to reciprocate the equipment to achieve the grinding of the rail, and the grinding...
