Abstract
The utility model provides a miter joint rail comprising two vertical planes and one inclined plane, wherein, the vertical plans are lengthways perpendicular to the rail on two sides, and the inclined plane and the rail are vertically of a sharp angle in the middle. When in construction, two rail heads are in opposite joint and are fixed on the two sides through joint plywood. The rail gap after assembled is a polyline rail gap. When the wheel passes through, a small wallop is exerted on the rail head, thereby reducing the noise, joint hurt, maintenance fee, and road resistance, and increasing the road safety factor.
Description
Technical field
The utility model discloses a kind of rail joint, particularly relate to a kind of Miter joint rail.
Background technology
Development along with society, progress of science and technology, the development of transportation, as the railway industry of communications and transportation also develop very fast, railway all has very big development, not only newly-built route every year, as old route, the speed of train raises speed several times, because the raising of speed also has new requirement to rail; At present, the rail of rail track all is the straight peen rail, the straight peen rail joint is one of three big weak links of track circuit, as shown in Figure 1, because rail gap and rail is vertical vertical, when wheel passes through the straight peen rail joint, wheel drops on whole rail gaps, rail is produced impact force, this impact force is along with the speed of a motor vehicle and rail gap increase and increase, be again the direct factor that causes joint disease and train noise, the annual according to statistics maintenance cost that is used to renovate joint disease and consumes accounts for more than 20% of railway line maintenance expense; Joint disease directly has influence on traffic safety in addition, also increases the resistance of train operation simultaneously, is badly in need of being improved.
The utility model content
According to the purpose of this utility model, shortcoming at above-mentioned straight peen rail joint existence, a kind of Miter joint rail is provided, its structure is faced directly with an inclined-plane by two and is formed, both sides are to face directly, vertically vertical with rail, middle inclined-plane and rail vertically acutangulate, because rail gap is made up of two vertical masonry joints and a R-joining, when wheel passes through the joint rail gap, just be pressed on the R-joining, be pressed in simultaneously again on two one steel rails, so just realized the continuity of rail, rail is produced very little impact force, thereby also can reduce caused noise of joint disease and maintenance cost, also reduce car resistance in addition, and increase the safety factor of driving.

The specific embodiment
To shown in the accompanying drawing 5, Miter joint rail of the present utility model faces (11) directly by two and an inclined-plane (12) is formed as accompanying drawing 2, and it is vertically vertical with rail that both sides are faced (11) directly; Middle inclined-plane (12) vertically acutangulates with rail; The rail head inclined-plane (12) at rail two ends is parallel, and all rail head of rail sections are the inclined-planes of a unified direction; Because being two vertical masonry joints and a R-joining, rail gap forms, when wheel passes through the joint rail gap, just be pressed on the R-joining, be pressed on two one steel rails again simultaneously, so just realize the continuity of rail, rail has only been produced very little impact force, thereby reduced joint disease and noise, also reduce maintenance cost and car resistance, and guaranteed traffic safety.
As shown in Figure 6, be embodiment of the present utility model, when the construction of rail, two one steel rail heads (1) are docked, rail gap is left in the centre, the rail temperature was determined when the size of rail gap was prepared according to rail, at both sides, docking section field joint clamping plate (2), penetrate bolt (3) then, spring washer (4) and nut (5) are installed again, it is 10mm that embodiment of the present utility model faces width directly, middle inclined-plane is 30 degree with the vertical acute angle that becomes of rail, each joint bolt, each 6 of nut and spring washers, rail gap after the assembling is a broken line type rail gap, when wheel passes through, rail's end portion is produced very little impact force, thereby reduce noise and joint disease, simultaneously also reduce maintenance cost and car resistance, increased safety factor of travel.
Claims (2)
1 one kinds of Miter joint rails is characterized in that: the end is faced directly with an inclined-plane by two and is formed, and both sides are to face directly vertically vertically with rail, and the centre is that inclined-plane and rail vertically acutangulate.
2 according to the described a kind of Miter joint rail of claim 1, and it is characterized in that: it is 10mm that said both sides are faced width directly, middle inclined-plane and rail vertically be 30 the degree angles.
