Problems solved by technology

The following shortcomings and deficiencies of this technology have limited its widespread popularization and further improvement of train speed:
[0003] 1. Although the welded rails are long, there are still many harmful joints in the buffer joint area, which is enough to cause the train with a speed of more than 500 kilometers per hour to violently bump;
[0004] 2. Expansion of the track, track crawling, cold shrinkage, broken rails, and fatigue broken rails occur from time to time, endangering driving safety;
[0005] 3. The welding and fabrication of long rails, transportation, installation and commissioning, maintenance and repair are extremely troublesome and costly
[0006] 4. The construction period is too long

Embodiment Construction

[0014] A kind of "extreme speed railway", the elastic fasteners fix the rails on the track bed, and the ends (1) and (7) of each two adjacent rails are directly connected to the elastic components with V-shaped sections without expansion joints, and are placed together on the same Inside the channel-shaped steel (10), the channel-shaped steel (10) is placed in the reserved groove of the wide-body concrete pillow and fixed by secondary grouting (9); the elastic component is composed of an elastic body (4) and a sheath (3); the elastic body (4) It is as wide as the upper surface of the rail ends (1) and (7), and is of the same height as the rail ends, and the longitudinal groove is obliquely opened on the side, which is a serpentine spring from the top view, in order to absorb the rail Thermal expansion; the sheath (3) is composed of two parts, with a longitudinal expansion joint between them for the expansion of the elastic body. ), the inner length is equal to the length of th...

Abstract

The 'extreme speed railway' has tracks fixed on railway bed by means of elastic track fasteners. It features that each two adjacent tracks are connected directly with one elastic assembly without expansion joint in between. The elastic assembly and the ends of the connected tracks are set in one section of channel steel back grouting fixed inside wide concrete sleeper. The elastic assembly consists of one elastic part and one sheath. The railway has the tracks connected with the elastic assembly comprising assembled machined parts to form one integral for train to pass in extreme speed.

Description

Technical field [0001] The invention relates to railway connection and machinery manufacturing expertise Background technique [0002] The currently known railway connection technology is seamless connection technology. It welds common rails to grow rails, and puts the accumulated thermal expansion in the buffer joint area for centralized processing. The purpose is to reduce the number of joints, reduce the damage of joints, and increase the speed of train operation. This technology has a history of nearly 100 years, and the current commercial operation speed has been increased to 300-350 km / h. Its effect is obvious, and its progress is also very slow. The following shortcomings and deficiencies of this technology have limited its widespread popularization and further improvement of train speed: [0003] 1. Although the welded rails are long, there are still many harmful joints in the buffer joint area, which is enough to cause the train with a speed of more than 500 kilo...
