Abstract

A seaming technology for railroad track with 45degreeinclination can efficiently conquer attacking, shaking and hammering generated by the gap which is set aside when the road wheel rolls by the joint of traditional track in rail transport, and prolong loose time of roadbed under the joint. Only original 90degreeshearing against to the length direction is changed into 45degreeshearing during track production. Left-right track is symmetric and sharp angle is abated. Track is jointed by traditional method, but the gap H (expressed by figure) between rear and front track is equal to the length set aside in traditional joint method and inclination degree of left-and-right tracks is symmetrical so as to satisfy the designing demand. The invention is especially applied in comfortable and express trunk line demanded by passenger and high-cold zone and tundra influenced by shake sensitively.

Description

45 ° of sloping railway track joint techniques

Technical field

The invention belongs to the railway construction rail lay in the improvement of rail joint technique, can effectively eliminate by the rail gaping of joints and cause vibrations and noise in the train operation, delay the loosening time of rail seam crossing roadbed.

Background technology

The seam of present two rails in front and back all adopts perpendicular to the train direction of advance, and according to this place region weather conditions, leaving certain reasonable clearance splices, it has solved the problem of expanding with heat and contract with cold of rail, make two rails remain parallel, so that train passage, the manufacturing that has simultaneously also solved rail, transportation and installation question, but because the existence of gaping of joints, wheel made of iron is produced through herein the time impact, vibrations and noise are particularly when launch train or even more serious when travelling at a slow speed, the seam crossing that tangible example is the station rail weares and teares especially easily, and roadbed herein is also loosening especially easily.

Summary of the invention

In order to overcome the impact that causes during by the rail gaping of joints when train wheel, vibrations and and the noise that sends, avoid bringing discomfort to occupant and passenger, prolong the loosening time limit of ground of seam crossing, reduce the wearing and tearing of the seam crossing of rail, to change the gap with current of traffic angle at 45 perpendicular to the gap of current of traffic into, to eliminate those shortcoming that original seam method is brought.

The technical scheme that the present invention takes is: in the rail manufacture process, change 90 ° when in type rail is cut off by former specific length and be cut to 45 ° of cut-outs, left and right sides rail is symmetry each other, and with the acute angle abate.Also symmetry installation of rail about during installation.Gap between two rails in the front and back of one side should be measured by current of traffic, adopts that traditional rail splicing method is calculated, predetermined gap (seeing accompanying drawing) if must be equal to this region.Therefore, when train wheel is rolling from a back rail during to last rail (come with the train direction of advance fixed) motion, the contact surface of wheel and rail is progressively to be shifted to last rail by a back rail, that is to say because present rail seam exists 45 ° of oblique angles, the contact area of a wheel and a back rail reduces gradually because of train rolls forward, but the contact area of wheel and last rail also increases simultaneously gradually, thereby make train wheel in the whole service process be close to the rail face all the time, eliminated wheel intermittence that rolling current situation necessity runs in the conventional seams method, also just eliminated impact, vibrations and noise, and improved wear condition herein.

This beneficial effect of the invention is:

(1) changes by part, need not increase any component, just can effectively overcome vibrations and the noise that produces in the train travelling process, make railway transportation humanized rail; Particularly overcoming of vibrations do not have the maintenance of appointing train and railway bed and all brings very big benefit, is more suitable for severe cold areas and tundra etc. and promotes, uses shaking responsive area.

(2) change to rail production division technology and equipment neither be very big.

(3) also comparatively convenient to the improvement of original railway: an energy travels on railway as long as make, and can cut and the locomotive that can punch gets final product.The rail of paving the way still can utilize original equipment.

Description of drawings

Among the figure: plain cushion (3) clamping plate (4) rails (5) nut (1) nut (2))

H-is the gap between two rails in front and back

The specific embodiment

New construction: after will transporting to the building site by the production of the drawing after improving rail, get final product according to traditional mounting method, will note 2 points here: bilateral symmetry is wanted at two rail angles of inclination one).Two) the gap H before and after between the seam of rail is meant the distance that This train is bound for XXX, and the gap that calculates should equal this highway section design department by conventional method splicing rail the time.

Alteration work: in the period that allows construction, the locomotive of will constructing is opened railway, constantly each root rail is cut, punches in the mode that retreats, in order manufactured rail is spliced one by one with track-laying machine, the gap of seam and original gaping of joints are consistent (referring to the distance that This train is bound for XXX) again.The each construction of suggestion, the radical that the length summation of the cut-out of rail can be increased is divided exactly.

Claims

A kind of 45 ° of novel sloping railway track joint techniques, the gap of leaving when it is characterized in that only with the two rail splicings in traditional front and back, by originally perpendicular to current of traffic, change the current of traffic that favours at 45, about two rails symmetry each other, and gap length constant (with respect to current of traffic), pressing plate, bolt, nut and fastening method are constant.New rail can be in manufacture process cuts two ends section at 45; Old rail is as long as make the locomotive that can walk, can cut, can punch, the transformation of can constructing on the spot on railway.
