Detachable guide edge and inner side rerailer

Abstract

The invention relates to auxiliary railway equipment and discloses a detachable guide edge and inner side rerailer, which overcomes the defects that the original rerailer cannot be firmly fixed to rails, cannot effectively guid the rerailing due to absence of a rim slot and has a short rerailing distance, and an included angle between a guide edge and the steel rail after installation is large. According to the detachable guide edge and inner side rerailer, the upper sliding surface of the inner side rerailer is a curved surface, and the side face of the inner side rerailer is provided with a reinforcing frame; crossed gridded reinforcing ribs are arranged in the frame in a staggered mode; an arched notch which corresponds to a sleeper is arranged in the middle of the bottom surface of the rerailer, the side face of the bottom surface of the rerailer is provided with a clamping groove, and the two ends of the bottom surface of the rerailer are provided with insertion slots, jacks and mounting hole grooves matched with configuration bolts; the guide edge and the inner side rerailer are detachably arranged; the cross section of the guide edge is in the shape of a paraboloid or a triangle or a rectangle or a trapezoid; and an included angle between the guide edge and the steel rail ranges from 15 to 25 degrees. The detachable guide edge and inner side rerailer can meet the requirements on rescue under different road conditions and is firm to mount, easy to guide, light in weight and convenient to mount and transport.

Description

technical field [0001] The invention relates to railway auxiliary equipment, in particular to a detachable guide rib and inner rerailer. Background technique [0002] At present, with the rapid development of my country's railway transportation, derailment of railway locomotives also occurs occasionally. Once derailment occurs, it may cause serious loss of personnel and property, so rerailers also appear in large numbers. Existing rerailers can be divided into herringbone rerailers, sea cucumber type rerailers, two-way rerailers and single-piece rerailers from the structure, but they all have some problems, such as not universal, large guide angle , The installation is too high and the hardness of the material is poor. Chinese patent ZL200920092182.4 discloses "A Rerailing Device". The rerailing device relies on iron chains to fix the rails, and the force is not stable when rerailing, and it is easy to collide with parts at the bottom of the locomotive when it is installed ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is: aiming at the deficiencies of the prior art, to propose a detachable guide rib and an inner rerailer, which overcomes the inability of the original rerailer and the track to be fixed firmly and the lack of wheel flange grooves to effectively guide the Disadvantages of re-tracking, short re-tracking distance, poor casting material hardness and large angle between guide rib and rail after installation
