Abstract
A silent steel rail joint for railway is disclosed, which consists of a V-shaped block (1) and a wedge block (2). A V-shaped opening is formed on one side of the V-shaped block (1), a positioning mortise-tenon (3) is formed at central position of the opening, a positioning mortise-tenon through hole (4) is formed at central position of the wedge block (2), the wedge block (2) is wedged into the opening of the V-shaped block (1), and the positioning mortise-tenon (3) on the V-shaped block (1) is inserted into the positioning mortise-tenon through hole (4) of the wedge block (2). The advantages are: the gap at steel rail joint forms small acute angle instead of vertical angle with the steel rail, so that the direct collision between train wheel and the entire gap can be avoided; the positioning mortise-tenon (3) is firmly positioned in the positioning mortise-tenon through hole (4) to form smooth and uniform joint surface, round tip part of the wedge block (2) faces downwards, so the wheels of train in reverse driving direction will not touch the tip part, so as to avoid sound of collision, allebyte abrasion, and prolong service lives of train wheel and steel rail.
Description
Technical field
The utility model relates to a kind of train railway rail joint device, is used for the train railway rail joint and connects.
Background technology
Deformation takes place because of variations in temperature in railway track, makes the rail bending for preventing the elongation of rail expanded by heating, leaves the slit about 10mm at the rail joint place, because the slit is vertical with rail, when train passed through, head-on clashed into simultaneously in wheel and whole piece slit, sends the strong bump sound.In order to reduce or reduce to clash into the sound, China railways department once taked some technical measures, changed long rail into as lacking rail; Last century end, with the slit seam at rail joint place, the seam material strain has characteristics alone on the arterial railway main line in China railways department, when rail is subjected to thermal stretching, seam material pressurized shortens, and cooling causes that seam material tension stretched thereupon when rail shortened.After the seam of the slit at rail joint place, train does not have a bump sound again through out-of-date, only hears the grating of wheel and rail.Yet,, seam this technology in rail joint place is not extensively promoted because of multiple reason.Therefore, solve the bump sound that the rail joint place produces, remain the technical problem of a pendulum in face of people.
Summary of the invention
The utility model is intended to release a kind of novel joint that is installed in the rail joint place, and during this joint of train wheel process, the sound that do not knock claims the silent rail joint.
The technical solution of the utility model is:
This joint is made of vee-block and wedge, and an end of vee-block is " V " font opening, and there are location male and female tenon, location male and female tenon and vee-block global formation in the centre of opening.Wedge is wedge shape, and the tip of wedge is downwards slick and sly, and there is location male and female mortise break-through in the wedge centre, and the position of location male and female tenon is corresponding mutually with the position of location male and female mortise.In the opening of wedge wedging vee-block, and the location male and female tenon on the vee-block injects in the location male and female mortise on the wedge, the mutual interlock of vee-block and wedge and firmly locating, and the upper surface of vee-block upper surface and wedge is smooth to be harmonious.
When on the railway track of having completed the silent rail joint being installed, the position of mobile rail does not only need to cut the sanction rail identical with the silent rail joint length at the rail joint place, silent rail joint plug-in mounting is welded between the former rail joint again.For the railway of new shop, need not cut sanction, only need that the silent rail joint is welded in rail joint and get final product.
The utility model has the advantages that: not vertical in slit, rail joint place with rail, and angled very little acute angle when train passes through, avoids wheel and whole piece slit head-on to clash into simultaneously; Location male and female tenon firmly is positioned to locate in the male and female mortise, the smooth unanimity of joint surface, and the wedge tip is downwards slick and sly, and the reverse wheel that crosses can not hit and bump the tip, therefore can not produce impact sound.Because do not clash into, wheel steadily contacts with rail, reduce noise, alleviate wearing and tearing, can prolong the application life of wheel and rail.
Description of drawings
Fig. 1, the utility model structural representation.
Fig. 2, the utility model are not mounted to whole schematic diagram.
Among the figure: 1, vee-block, 2, wedge shape, 3, location male and female tenon, 4, location male and female mortise.
The specific embodiment
In conjunction with the accompanying drawings, introduce the specific embodiment of the present utility model:
The utility model is made of vee-block (1) and wedge (2), and an end of vee-block (1) is " V " font opening, and there are location male and female tenon (3), location male and female tenon (3) and vee-block (1) global formation in the centre of opening.Wedge (2) is wedge shape, and the tip of wedge (2) is downwards slick and sly, and there is location male and female mortise (4) break-through in wedge (2) centre.The position of location male and female tenon (3) is corresponding mutually with the position of location male and female mortise (4).In the opening of wedge (2) wedging vee-block (1), and the location male and female tenon (3) on the vee-block (1) injects location male and female mortise (4) lining on the wedge (2).
The opening angle of vee-block (1) is 25 °.
Claims (1)
1, the silent rail joint, it is characterized in that constituting by vee-block (1) and wedge (2), one end of vee-block (1) is " V " font opening, there is location male and female tenon (3) in the centre of opening, location male and female tenon (3) and vee-block (1) global formation, wedge (2) is wedge shape, the tip of wedge (2) is downwards slick and sly, there is location male and female mortise (4) break-through in wedge (2) centre, the position of location male and female tenon (3) is corresponding mutually with the position of location male and female mortise (4), in the opening of wedge (2) wedging vee-block (1), and the location male and female tenon (3) on the vee-block (1) injects location male and female mortise (4) lining on the wedge (2).
