Grinding mechanism for track welding spots

Abstract

The invention relates to the technical field of track welding and grinding equipment, and discloses a grinding mechanism for track welding spots. The grinding mechanism comprises a steel rail, wherein a walking bracket is clamped on the surface of the steel rail, a track sliding plate is arranged at the bottom end of an inner cavity of the walking bracket, a track sliding groove which is through left and right is formed in the track sliding plate, a vertically-through fixed sliding groove is formed in the track sliding plate, and a grinding mechanism body is movably connected into the track sliding plate in a sleeved mode. According to the grinding mechanism for the track welding spots, the track sliding plate, the track sliding groove and the fixed sliding groove are arranged, so that the grinding mechanism can drive a grinding disc on the grinding mechanism to conduct movable grinding operation on the surface of the steel rail along the track of the track sliding groove; and compared with an existing track grinding mechanism, the whole grinding mechanism does not need to be moved when the welding spots on the steel rail are ground, operation of the grinding mechanism is greatly simplified, time and labor are saved when the grinding mechanism is used, and controllability and stability are relatively high.

Description

technical field [0001] The invention relates to the technical field of orbital welding and grinding equipment, in particular to a grinding mechanism for orbital welding spots. Background technique [0002] The laying of railway rails is to weld several sections of rails to form a whole track, but when two adjacent sets of rails are welded, due to welding technology, the surface of the rails is welded. For the safe and stable operation of the track, the surface of the track must be kept flat. Therefore, after the track is welded, it is necessary to polish the welding points to ensure the smoothness of the track. [0003] However, due to the curved surface structure design of the track surface, when the existing track welding and grinding equipment mechanism is grinding its welding points, it needs to swing the grinding mechanism as a whole so that the grinding sheet on the track surface can be polished along the curved track of the track surface , As a result, the operation ...

Problems solved by technology

[0005] The invention provides a grinding mechanism for track solder joints, which does not need to move the grinding mechanism as a whole so that the grinding sheet on it can move along the track of the curved surface of the track, the operation is simple, convenient, time-saving and labor-saving, and the accuracy and stability are relatively high. High advantages, solve the problem that due to the curved surface structure design of the track surface, when the existing track welding and grinding equipment mechanism grinds its welding points, it needs to swing the grinding mechanism as a whole so that the grinding sheet on it can follow the curved surface of the track surface The orbital grinding operation makes the operation of the orbital welding and grinding equipment mechanism more cumbersome during use, which consumes a lot of physical strength for the operator, and the accuracy and stability are poor, and the work efficiency for orbital welding point grinding is relatively low.
