Problems solved by technology

At present, when the high-speed turnouts of passenger-dedicated lines leave the factory, the switch packs and ships the entire set of turnouts to the site. The basic rail and the point rail are closely matched, and the elastic iron backing plate is assembled under the rail parts according to the distance between the switch sleepers. However, the point is not aligned. The bottom of the rail for overall protection
At the laying site of the point rail bottom, when the hoist lifts the point rail assembly, the sling or spreader will directly contact with the point rail bottom, which causes scratches on the point rail bottom, and the assembly and adjustment When installing rail components, it is necessary to open and close the switch rail. The tools used by the construction personnel will directly contact the bottom of the switch rail and apply force to it, which will also cause a certain degree of damage to the bottom of the switch rail.

Abstract

The invention discloses a switch rail bottom protective sleeve and a preparation method and application thereof, the protective sleeve comprises a bottom, a first side wall and a second side wall are vertically arranged at the two ends of the bottom respectively, and the first side wall and the second side wall are located on the same side of the bottom; a first hook-shaped structure and a second hook-shaped structure are arranged at the ends, far away from the bottom, of the first side wall and the second side wall correspondingly, the first hook-shaped structure and the second hook-shaped structure extend from one end of the first side wall and one end of the second side wall to the center line direction of the bottom correspondingly, and the extended ends are located on the sides, far away from the bottom, of the first side wall and the second side wall; the inclination of the first hook-shaped structure is 1: (2.76-13); and the inclination of the second hook-shaped structure is 1: (17-20). The protective sleeve is directly fixed to the rail bottom of the switch rail through the structure of the protective sleeve, on the premise that laying of the switch rail is not affected, damage to the switch rail due to direct contact between a lifting appliance or a construction tool and the rail bottom of the switch rail is avoided, and the rail bottom of the switch rail is effectively protected.

Description

technical field [0001] The invention relates to the technical field of turnouts, in particular to a switch rail bottom protective cover and a preparation method and application thereof. Background technique [0002] With the development of high-speed rail, the demand for high-speed turnouts is increasing, and the protection of high-speed turnout rails is becoming more and more important. At present, when the high-speed turnouts of passenger-dedicated lines leave the factory, the switch packs and ships the entire set of turnouts to the site. The basic rail and the point rail are closely matched, and the elastic iron backing plate is assembled under the rail parts according to the distance between the turnout sleepers. However, the point is not aligned. The bottom of the rail is fully protected. At the laying site of the point rail bottom, when the hoist lifts the point rail assembly, the sling or spreader will directly contact with the point rail bottom, which causes scratch...
