Steep hill railway adjustable anti creeping stake device

Abstract

The invention discloses a soft adjustable anti-crawling pile device of railway with steep slope for railway transportation of deep open-pit mine, comprising vertical piles (4) constituted by two steel rails, beam (1) constituted by a steel rail and rubber wedge oblique pad wedging between the beam (1) and cement pillow / wood pillow (3). The invention is suitable for the railway with steep slope, of which the slope is 40per mill -50per mill . It is provided with simple structure, convenience installation and good anti-crawling performance. In using, the space between anti-crawling pile and track panel is adjusted automatically by gravity to combine the anti-crawling pile and the track panel tightly so as to prevent the crawling effect of rail ladder. At the same time soft material is used to prolong the service life and decrease the maintenance workload.

Description

technical field [0001] The invention relates to an anti-climbing pile device for railway transportation in deep concave open-pit mines, in particular to an anti-climbing pile device for steep slope railway transportation with a gradient of 40‰ to 50‰. Background technique [0002] Steep slope railway transportation technology is mainly used in large-scale open-pit mines. It can shorten the distance of railway transportation, reduce the investment in transportation equipment, improve the transportation mode of mine development, improve transportation efficiency, extend the depth of railway transportation, save transportation costs, and improve the ecological environment at the deep level of the stope. It is a new and practical transportation technology for deep concave open-pit mines, making full use of mineral resources and stabilizing the service life of mines. But when the train loaded with ore runs on the steep slope railway with a larger gradient,...

AI Technical Summary

Problems solved by technology

At present, there is no anti-climbing pile device for steep slope railways in China

The gentle-slope railway building with a slope below 30‰ adopts the "Overlord Pile" anti-climbing device, such as the device introduced in the eighth special issue of "China Mining" in 1999 (total No. 42), but this anti-climbing pile device is rigid and frequently withstands heavy loads. Large vibration and crawling force impact loads can easily cause damage to the anti-climbing piles. The most common ones are looseness, inclination, and failure.
