Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As Fig. 3, Fig. 4, shown in Fig. 8, the utility model tram fastener system, comprise, screw spike 1, plain washer 2, spring 3, service sleeve 4, gauge apron 5, backing plate 6, height adjusting cushion plate 7 under rail, overall height adjusting cushion plate 8 and pedestal 9, described screw spike 1 is through plain washer 2, spring 3, gauge apron 5 be embedded in service sleeve 4 in concrete sleeper 9 and be connected, spring 3 is pressed in gauge apron 5 and grooved rail structure by screw spike, described pedestal 9 is formed with right angle shoulder block, base bottom surface contacts with concrete, close contact inside the outside of described gauge apron 5 and pedestal 9, the lateral surface of gauge apron 5 near rail side contacts with rail, backing plate 6 is installed between rail foot and pedestal 9.When the fastener of tram needs elevation to adjust, the maximum adjustment amount 10mm of height adjusting cushion plate 7(under backing plate 6 times mounting rails), or under described rubber mat plate or compound backing plate 6 times simultaneously mounting rail height adjusting cushion plate 7 and the maximum adjustment amount 30mm of overall height adjusting cushion plate 8().
As shown in Fig. 5, Fig. 6, Fig. 8, screw spike 1 stretches in the service sleeve 4 in concrete sleeper, be easy to laying and the maintenance in later stage, the head of a nail of screw spike 1 is turret head 1a, screw spike 1 has circular arc type ridge 1b, canine tooth is optimized, reduces transportation and collide with to the damage of bolt thread; Sleeve upper end arranged outside two encloses protruding 4a, prevents sleeve upper end use procedure Fracture from coming off; Plain washer 2 is set between screw spike 1 and spring 3, plays the effect of protection screw spike 1 and spring 3; Backing plate 6 is rubber mat plate or compound backing plate, backing plate provides elasticity for fastener system, rubber mat plate take natural rubber as material, compound backing plate with natural rubber and macromolecular material for material, during compound backing plate 6 nonrubber part employing macromolecular material 6a, the fastener resistance caused after avoiding existing compound backing plate to get rusty is on the contrary higher than the problem of common fastener.
As shown in figures 7 and 9, gauge apron 5 arranges the gear platform 5a raised up, and limits location of rail; Gauge apron both sides arrange diagonal rib 5b, increase baffle plate intensity; Groove 5c is provided with, location spring on rear side of gauge apron; The lateral outer side of gauge apron afterbody has convex shoulder 5d, this convex shoulder 5d and concrete sleeper shoulder block shape suitable, constraint gauge apron lateral displacement, gauge apron afterbody is right angle 5e, matches, and do circular arc process with pedestal 9 right angle shoulder block 9a.During tram fastener system gauge adjustment, adopt the gauge apron 5 of different model, gauge adjustment amount+8mm ~-12mm.The material of gauge apron 5 is macromolecular material.
The simple component of the utility model tram fastener system structure are few, can greatly save fastener material therefor, reduce tram construction cost, easy construction, and heighten with roll adjustment ability comparatively large, maintenance work amount is little; By the gauge apron of different model, realize roll adjustment ability; Height adjusting cushion plate and overall height adjusting cushion plate under rail are set under rubber mat plate, realize elevation adjustment; Except spring and bolt, all adopt nonmetals, extend fastener application life.Screw spike stretches in the service sleeve in concrete sleeper, be easy to laying and the maintenance in later stage, screw spike circular arc type ridge can reduce transportation and collide with to the damage of bolt thread, sleeve upper end arranged outside two encloses projection, can prevent sleeve upper end use procedure Fracture from coming off.During compound backing plate nonrubber part employing macromolecular material, the fastener resistance caused after avoiding existing compound backing plate to get rusty is on the contrary higher than the problem of common fastener, and adopt overall height adjusting cushion plate, the amount of heightening improves greatly; This fastener in-site installation is convenient, late maintaining maintenance load is little, and strong adaptability, can be widely used in streetcar track system.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to allow the technology personage being familiar with this field can understand the utility model content and be implemented, can not limit protection domain of the present utility model with this.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
