Abstract
The utility model relates to a two-stage spring highness adjusting device which is used for fixing and adjusting the highness of rails. The two-stage spring highness adjusting device is comprises a spike 1, a nut 2, a gasket 3, an elastic bar 4, a stop strip 5, an insulation rail gauge pad 6, an insulating buffer shim 7, a height-adjusting liner plate, an anti-rust cap 9, a big iron liner plate 11 and a big plastic liner plate 12. The two-stage spring highness adjusting device can increase the amplitude of the highness adjustment of the rails. The amplitude is changed from the original 0 mm to 25 mm to the present 0 mm to 50 mm. Simultaneously, the adjusting range of the rail gauge can be enlarged into-12-+20 mm. In addition, the high precision requirement of the trackway with the unbalance over balance of 2 mm can be satisfied. Two-stage spring highness adjusting device has the advantages of simple structure and easy application.
Description
The utility model relates to a kind of tightening means for height-adjusting device of fixedly railway track, especially a kind of two-stage elasticity tightening means for height-adjusting device.
The tightening means for height-adjusting device is a kind of being installed on the railway concrete sleeper, the fastener device that is used for fixing rail, behind the train running certain hour, sinkage appears in its rail, for smooth driving must be adjusted rail, existing tightening means for height-adjusting device, because its structure limit is 0-25mm to the scope of heightening of rail, and the amplitude that actual rail sinks is 0-50mm, so existing tightening means for height-adjusting device can not satisfy actual requirement, the two other rail is through after using for a long time, its gauge increases, also needs to adjust, but existing tightening means for height-adjusting device, adjusting range to gauge is little, can not thoroughly solve practical problem.
The purpose of this utility model is by the architecture advances to existing tightening means for height-adjusting device, develops a kind ofly can save the height of railway track and the fastener device of gauge significantly.
The utility model is made up of apart from pad 6, buffer insulation pad 7, height adjusting cushion plate 8, anti-rust cap 9, big iron chair 11, big plastic base plate 12 screw spike 1, nut 2, packing ring 3, spring 4, baffle plate 5, insulation rail, and its architectural feature has following 5 points:
1, baffle plate 5 is divided into four kinds of specifications:
1. baffle plate 5 bottom surfaces are wide is 77.8mm, and the retaining rail level height of baffle plate 5 is 55mm.
2. baffle plate 5 bottom surfaces are wide is 83.8mm, and the retaining rail level height of baffle plate 5 is 55mm.
3. baffle plate 5 bottom surfaces are wide is 75.8mm, and the retaining rail level height of baffle plate 5 is 55mm.
4. baffle plate 5 bottom surfaces are wide is 85.8mm, and the retaining rail level height of baffle plate 5 is 55mm.
2, the total length of screw spike 1 is 227mm, and its screw thread length is 80mm.
Distance to its top end face above the round platform of screw spike 1 is 107mm.
The embedding protruded length of screw spike 1 is 110-117mm.
3, insulation rail is a rectangle apart from pad 6, is made by nylon 6 or nylon 66.
4, big iron chair 11 length of rail grooved are 160mm, and going up wide is the wide 305mm of being under the 333.8-363.8mm, and thickness is 16mm-18mm
5, big plastic base plate 12 length of rail grooved are 162-166mm, and going up wide is 331.8-371.8mm, following wide be 305mm, thickness is 5mm-10mm.
Below in conjunction with accompanying drawing architectural feature of the present utility model is further specified.
Fig. 1 is that the rail one-level is heightened structural representation, also is rail assembling structure schematic diagram just, and it heightens amplitude is 0-25mm.Wherein the structural relation between each part is identical with each part structural relation in the existing fastener, as shown in Figure 1: earlier screw spike 1 usefulness Sulphur concrete mortar is separately fixed in two railway spike holes of sleeper, insulation rail is mated formation on the shoulder block of sleeper apart from pad 6, buffer insulation pad 7 is mated formation below rail 10, according to the actual conditions of just adorning at that time, determine whether to mat formation height adjusting cushion plate 8.And then the wide baffle plate 5 for 77.8mm and 83.8mm in bottom surface mated formation respectively on the screw spike 1 of rail 10 both sides.Pack into behind the spring 4.The rear end of spring 4 is pressed in the pit of baffle plate, and its front end is pressed in the bottom of rail 10, and the packing ring 3 of packing on screw spike 1 at last, nut 2 and anti-rust cap are the first dress program of rail 10 more than 9, also are that the one-level of rail 10 is heightened program.In order to increase the amplitude of accommodation, carry out the secondary adjustment, the screw spike 1 among Fig. 1, baffle plate 5 and insulation rail are 6 different with original structure apart from pad, have all carried out bigger improvement, and its concrete condition is all identical with existing part as other each parts as described in the above-mentioned feature.Two baffle plate 5 bottom width among Fig. 1 are different, and its retaining rail level height is the same, all is 55mm, and these two baffle plates 5 are installed in the both sides of rail 10 as one group, one of every side.Bottom width is that the baffle plate 5 of 75.8mm and 85.8mm is one group, uses as the secondary adjustment.
Fig. 2 is that rail 10 secondarys are heightened structural representation.After rail 10 used certain hour, appearance was sunk and gauge increases phenomenon, and general sinking this moment,, is all taken off the screw spike 1 when adjusting in Fig. 1 for ease driving must carry out the secondary adjustment to rail 10 for more than the 25mm.After rail 10 lifted certain altitude, be encased inside down the wide 305mm of being, going up wide is 357.8mm, and length is that 164mm, thickness are the big plastic base plate 12 of rail grooved of 5mm.And then be encased inside down the wide 305mm of being, upward wide is that 353.8mm, length are that 160mm, thickness are the big iron chair 11 of 16mm.After big plastic base plate 12 and big iron chair 11 adorns, with baffle plate 5 changes of 10 both sides of rail among Fig. 1 be bottom panel wide be the baffle plate of 75.8mm and 85.8mm, according to the program of Fig. 1 each parts is installed at last.
Because screw spike 1, baffle plate 5 and insulation rail in the utility model are structurally improved apart from pad 6,, increase to 0-50mm by original 0-25mm so that rail is heightened the amplitude increase is bigger.The steel plate 5 bottom width differences of rail 10 both sides ratio increased 4mm originally among Fig. 2 in addition, so the also corresponding increase of the regulated quantity of gauge.To 60 kilograms every meter rail gauge adjustable ranges be-8-+12mm with 75 kilograms every meter.Rail gauge adjustable range to 50 kilograms every meter and 43 kilograms is-12-+20mm and-8-+20mm.Can also satisfy the uneven favorable balance of track in addition is the high-precision requirement of 2mm, thereby can prolong the application life of rail.This device is easy to operate, when adjusting, need not the disturbance railway roadbed, need not to install anti-creep equipment at steep gradient and braking location again, can adjust rail height and gauge easily.In the sharp radius curve location, use the big iron chair 11 of rail grooved to heighten in addition, can reduce rail distance rod quantity.The big plastic base plate 12 of rail grooved in the utility model has elasticity preferably, can reduce abrasion and the impact force of wheel to rail 10, helps high speed traveling.
The utility model enforcement simple in structure, easy, easy to operate, the amplitude of accommodation is big, helps the vehicle smooth-ride.
