Abstract
The utility model relates to a connector of rails, in particular to wedge-shaped connected rails with obliquely crossed or overlapped tail ends. The wedge-shaped connected rails are characterized in that two rail connectors all take the wedge shapes, the wedge shape consists of two sections of planes which are vertical to the length direction of the rail and a section of inclined plane, the arrangement sequence of the wedge shape is the plane, the inclined plane and the plane, and the two sections of planes and the inclined plane are all vertical to the horizontal plane; the wedge surfaces at the connector of two rails are mutually corresponding, the inclined planes are mutually clung, and a certain clearance is left between the two sections of planes; and an angle from 0 degree to 20 degrees is formed between the inclined plane and the length direction of the rail. In the utility model, the wedge-shaped connectors are utilized to connected the rails so that wheels of a vehicle can realize the smooth transition at the seam of the rails, thereby the noise and the vibration can be eliminated, and the service life of the rail components and the vehicle can be improved; in addition, the clearance which expands with heat and contracts with cold is left, the structure is simple, the processing cost is low, other components of the rails are not changed, old rails can be transformed directly, and the practicability is strong.
Description
Technical field
The utility model relates to a kind of piecing devices of rail, and especially the wedge shape of terminal oblique of rail or overlap joint connects rail.
Background technology
At present, railroad track commonly used is an i iron, and rail joint is to flush, and a fixed gap is arranged between two lengths of rail, so can knock during locomotive operation, and the influence driving steadily and the speed of a motor vehicle and can cause damage to track.The seamless rail of long distance welding is adopted in some track traffic, and such rail can produce bending when temperature is higher, and the meeting double swerve also can produce certain noise during locomotive driving.
Chinese patent CN2437563Y discloses a kind of rail Shock-damping joint, it comprises linking rail, joint bar, joint backing plate, it is the isosceles trapezoid of miter angle that linking rail rail level becomes the base angle, and rail head rail level becomes the angle stake of miter angle, is connected rail becomes miter angle with the rail capitiform oblique gap.This patent rail joint is to adopt oblique connection, but still gapped between the rail, and has increased parts such as linking rail, joint bar, joint backing plate, complex structure, and cost is higher.
The utility model content
The purpose of this utility model is to provide a kind of wedge shape to connect rail, and this rail can effectively be eliminated the locomotive vibration that cause in the rail gap, and simple in structure, and it is convenient to implement.
The utility model is achieved in that a kind of wedge shape connects rail, two rail joint places are wedge shape, this wedge shape is made up of two sections plane and one section inclined-planes perpendicular to the rail length direction, putting in order of wedge shape is plane, inclined-plane, plane, and two sections planes and one section inclined-plane are all perpendicular to horizontal plane, the joint lozenges of two rails in correspondence with each other, the inclined-plane is close to mutually, between two sections planes certain interval is arranged all.
Described inclined-plane becomes 0～20 degree angle with the rail length direction.
The utility model is compared with the rail joint of prior art has following beneficial effect: the utility model utilizes wedge joint that rail is connected, make locomotive wheel in the smooth transition of track interface place, do not produce bump, can eliminate noise and vibrations, improve the application life of rail parts and locomotive, improve motor supply shop's vehicle speed, and the utility model leaves the gap of expanding with heat and contract with cold, simple in structure, processing cost is low, the rail miscellaneous part does not change, and can also directly transform old rail, and is practical.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 connects the rail front schematic view for the utility model wedge shape;
Fig. 2 connects the rail schematic top plan view for the utility model wedge shape;
Among the figure: 1 rail A, 2 first plane A, 3 second plane A, 4 inclined-plane A, 5 rail B, 6 first plane B, 7 second plane B, 8 inclined-plane B.
The specific embodiment
Referring to Fig. 1, Fig. 2.A kind of wedge shape connects rail, two rail joint places are wedge shape, this wedge shape is made up of two sections plane and one section inclined-planes perpendicular to the rail length direction, putting in order of wedge shape is plane, inclined-plane, plane, and two sections planes and one section inclined-plane be all perpendicular to horizontal plane, the joint lozenges of two rails in correspondence with each other, the inclined-plane is close to mutually, between two sections planes certain interval is arranged all, described inclined-plane becomes 0～20 degree angle with the rail length direction.The first plane A2 of rail A1 and the first plane B6 of rail B5 are corresponding, and the second plane A3 of rail A1 and the second plane B7 of rail B5 are corresponding, and the inclined-plane A4 of rail A1 and the inclined-plane B8 of rail B5 are close to mutually.
Wedge shape connects rail and both can be processed through machine-tooled methods such as milling machine or line cuttings by i iron, each sharp corner of wedge shape carries out chamfering or rounding according to a conventional method to be handled, the utility model wedge shape connection rail also can be transformed with old rail machine in addition, process simple and convenient, with low cost.Other links of rail such as pressing plate, set bolt, packing ring etc. are the existing conventional parts.
Claims (2)
1, a kind of wedge shape connects rail, it is characterized in that, two rail joint places are wedge shape, this wedge shape is made up of two sections plane and one section inclined-planes perpendicular to the rail length direction, putting in order of wedge shape is plane, inclined-plane, plane, and two sections planes and one section inclined-plane be all perpendicular to horizontal plane, and the joint lozenges of two rails in correspondence with each other, the inclined-plane is close to mutually, between two sections planes certain interval is arranged all.
2, wedge shape as claimed in claim 1 connects rail, it is characterized in that, described inclined-plane becomes 0～20 degree angle with the rail length direction.
