Abstract
The utility model discloses a fastening piece for an auxiliary rail, comprising an under-rail cushion plate for pressing between a steel rail and a sleeper, wherein embedded sleeves are fixed in the sleeper and below the under-rail cushion plate; rail spikes which are in threaded connection with inner holes of the embedded sleeves are arranged in the under-rail cushion plate in a penetrating manner; fastening plates matched with the steel rail are sheathed on the rail spikes; a boss integrated with each fastening plate is arranged between each fastening plate and the under-rail cushion plate in a supporting manner; a blocking shoulder matched with the steel rail in a pushing manner is fixed at the part on the lower surface of each fastening plate between the steel rail and each rail spike; and flat washers and spring washers are arranged above and below the rail spikes and between the fastening plates and nuts of the rail spikes in a vertical direction. The fastening piece has the advantages that the structure is simple, the disassembly is convenient, and the installation requirement for the auxiliary rail can be met.
Description
Technical field
The utility model relates to a kind of rail fastening, is specifically related to non-fragment orbit and has the changeover portion track auxiliary rail between the tiny fragments of stone, coal, etc. track to use fastener.
Background technology
At present, on the occasion of the peak period of China Railway High-speed Line for Passenger Transportation and inter-city passenger rail construction, on the same line road, existing non-fragment orbit also has tiny fragments of stone, coal, etc. track.Non-fragment orbit with have tiny fragments of stone, coal, etc. track to have the inconsistent phenomenon of rigidity, as not adding processing, can produce rigidity sudden change in transitional region.Evidence, during vehicle process rigidity saltation zone, the accessory power effect obviously increases, and causes roadbed to produce distortion, causes track irregularity, and this problem is along with the raising of train speed is more serious.In order to ensure train operation comfort level, stationarity and reliability; Non-fragment orbit with have tiny fragments of stone, coal, etc. track boundary that the elasticity transition section should be set; Between two strands of stock rails; Two one steel rails are set make auxiliary rail, realize that through increasing the section of track bending rigidity orbit rigidity is even along transition to increase rigidity of track panel.The stock rail fastener of changeover portion is identical with main track, and the auxiliary rail fastener need design again.
The utility model content
The purpose of the utility model provides a kind of fastener that is applicable to auxiliary rail.
The utility model adopts following technical scheme: a kind of auxiliary rail is used fastener; Comprise and be used to be fitted in the railway rail pad between rail and the sleeper; The below that is positioned at railway rail pad in the sleeper is fixed with service sleeve; Be equipped with the railway spike that is connected with the service sleeve inner hole thread in the said railway rail pad, be arranged with the buckle with the rail compression fit on the railway spike, support being provided with the convexity that is wholely set with buckle between buckle and the railway rail pad; And with partial fixing between the railway spike shoulder block that cooperates with the rail pushing tow is arranged at rail on the soffit of buckle, between the nut of buckle and railway spike, be pressed with plain washer and spring washer on the railway spike up and down.
Said railway rail pad comprises plastic base plate, and the quantity of plastic base plate is one or two of closed assembly up and down.
Said railway rail pad also comprises steel height adjusting cushion plate and the plastics height adjusting cushion plate that is stacked in up and down between plastic base plate and the sleeper, offers the installing hole that supplies said railway spike to pass on steel height adjusting cushion plate and the plastics height adjusting cushion plate.
The threaded rod surfaces coated of said railway spike is provided with the slushing oil layer.
Adopt the auxiliary rail of said structure to use fastener, between rail and the sleeper railway rail pad is set, and the thickness of railway rail pad requires to lay according to actual design; To guarantee that auxiliary rail has suitable height; The service sleeve that railway spike passes in railway rail pad and the sleeper is connected, and good stability is not fragile; And buckle compresses rail under the effect of railway spike, simultaneously on the soffit of buckle between rail and railway spike partial fixing the shoulder block that cooperates with the rail pushing tow is arranged, prevent the rail lateral displacement; Sheathed spring washer can cushion the impact of rail to railway rail pad on the railway spike.This fastener structures is simple, and convenient disassembly can satisfy the installation requirement of auxiliary rail.
Description of drawings
Fig. 1 is the example structure sketch map of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A portion enlarged drawing of Fig. 1.
The specific embodiment
The utility model auxiliary rail is with the embodiment of fastener: like Fig. 1, Fig. 2, shown in Figure 3, the railway rail pad 9 of fastener is fitted between rail 2 and the sleeper 1, when the design thickness of railway rail pad 9 is no more than 10mm; Generally speaking; Railway rail pad 9 is the thick plastic base plate of 3mm, and in particular cases, railway rail pad 9 is the thick plastic base plate of 4-10mm; The use that can certainly superpose, but the sum of plastic base plate is no more than two; When the design thickness of railway rail pad 9 surpasses 10mm, be pressed with steel height adjusting cushion plate and plastics height adjusting cushion plate between plastic base plate and the sleeper 1 up and down.The below that is positioned at railway rail pad 9 in the sleeper 1 is fixed with service sleeve 10; The endoporus of service sleeve 10 has internal thread; Be equipped with the railway spike 4 that is threaded with service sleeve 10 in the railway rail pad 9 from top to bottom; Be arranged with buckle 7 on the railway spike 4 with rail 2 compression fit; The bottom surface section away from rail 2 of buckle 7 is fixed with railway rail pad 9 and supports the convexity that cooperates, and in order to prevent laterally moving of rail 2, the partial fixing on the soffit of buckle 7 between rail 2 and railway spike 4 has the shoulder block that cooperates with rail 2 pushing tows.Between the nut of railway spike 4 and buckle 7, be arranged with spring washer 6 on the said railway spike 4, be top-loaded with plain washer 5 between the nut of spring washer 6 and railway spike 4, plain washer 5 is sheathed on the railway spike 4.
Be coated with the slushing oil layer on the threaded rod surface of said railway spike 4, thereby prevent that service sleeve 10 inside from getting rusty.
When the foregoing description is specifically used; Laid rail lower bolster 9 between rail 2 and sleeper 1; The confession railway spike 4 that makes railway rail pad 9 is corresponding with service sleeve 10 endoporus in the sleeper 1 through installing hole, and railway rail pad 9 puts plain washer 5, spring washer 6 and buckle 7 according to the designing requirement selection with railway spike 4 successively; And on the threaded rod of railway spike 4, be coated with slushing oil, be screwed into then in the service sleeve 10.
