Abstract

The invention discloses a creeping prevention elastic device for a large deep open-pit mine steep slope railway track. The device is composed of B-shaped elastic strips (6) made from rolled steel and a fixing clamp (2) in a combined mode. The B-shaped elastic strips (6) are used in pair, are mounted on the upper surface of a sleeper (7) through adjusting nuts (4) and are clamped on the bottom faces of the two sides of a base of a steel rail (1). The lower portion of the fixing clamp (2) is mounted on the side face of the sleeper (7) through a fixing nut (3). Clamping strips on the two sides of the upper portion of the fixing clamp (2) are clamped on the base of the steel rail (1). Clamping force of the creeping prevention elastic device composed of the pair of B-shaped elastic strips (6), the fixing clamp (2), the adjusting nuts (4) and the fixing nut (3) is adjusted to be no less than 15.68 KN per sleeper. The creeping prevention elastic device can bear longitudinal force generated by locomotive running to the track, and the longitudinal force and consolidation force between the steel track and ballasts are in balance, so that the steel track is prevented from moving along the sleeper under the action of wheels of running trains.

Description

technical field [0001] The invention relates to an anti-climbing device for railway tracks, in particular to an anti-climbing device for steep-slope railway tracks in open-pit mines, which is especially suitable for application in large-scale deep concave open-pit mines in steep-slope railway transportation systems with a gradient of 40‰-50‰. Background technique [0002] In the steep-slope railway transportation system of open-pit mines, a creeping force is applied to the track during the train’s travel. When the force exceeds the track resistance, it will cause the track to move, which is called track crawling. Track crawling includes two aspects: 1. It is rail crawling, and the rail moves longitudinally along the sleeper under the action of the train wheels. The second is rail ladder crawling, which refers to the longitudinal movement of the rail row along the track bed under the action of the running train wheels. Crawling can seriously disrupt the normal operation of a...
