Problems solved by technology

However, strengthening the fastening pressure of fasteners requires higher material properties of fasteners, which affects the service life of fasteners; under the action of train loads, it is often difficult to meet safety requirements only by relying on ballast resistance. Currently, anti-climbing devices are made of cast iron. About 5% of the lock rail sleeves are broken, and due to vibration, dripping oil, water and other objects on the train, and the poor elasticity of cast iron, the anti-climbing device is loose, resulting in anti-climbing failure. It needs to be turned left and right, and the existing track anti-climbing device needs to be inserted into the ballast bed, so it cannot be applied in the turnout

Abstract

The invention relates to the technical field of rail transit, in particular to a novel steel rail anti-climbing device which comprises a stock rail and a switch rail, and the stock rail and the switchrail are installed on sleepers. A first limiting device is fixedly arranged on the inner side of the stock rail, and an anti-disengaging device is fixedly arranged on the inner side of the switch rail and matched with the first limiting device. Second limiting devices are arranged on the outer side of the stock rail and the outer side of the switch rail respectively and matched with fixing devices, and the fixing devices are fixed to sleepers. According to the invention, the point rail in the turnout can be well prevented from creeping.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a novel anti-climbing device for rails. Background technique [0002] Aiming at the anti-climbing problem of railway rails, existing technologies mainly focus on strengthening the buckle pressure of fasteners to keep the relative movement between rails and sleepers; compacting the ballast bed to increase the longitudinal resistance of the ballast bed; such as pin-type anti-climbing devices. However, strengthening the fastening pressure of fasteners requires higher material properties of fasteners, which affects the service life of fasteners; under the action of train loads, it is often difficult to meet safety requirements only by relying on ballast bed resistance. Currently, anti-climbers are made of cast iron. About 5% of the lock rail sleeves are broken, and due to vibration, dripping oil, water and other objects on the train, and the poor elasticity of cast iron, the ant...
