Abstract
The utility model relates to a self-locking spring sheet fastener with adjustable fastening pressure for rails, belonging to the rail accessories for fixing rail strips on rail bearings. The utility model is characterized in that an inserting position of a spring sheet and a fastening socket is provided with an anti-loosing structure; a fastening pressure adjusting device is combined of rail tread blocks and adjusting blocks. The self-locking spring sheet fastener with reliable work can effectively prevent the spring strips from loosening and falling off in use. The fastening pressure adjusting device can be combined according to the needed fastening pressure. With easy construction and material saving, the utility model is suitable for installing new railways with standard rails and reforming old railways.
Description
The rail that buckle press is adjustable self-locking elastic bar fastener belongs on the sleeper the fixedly railroad track annex of rail bar.
The existing fixedly elastic bar fastener of rail bar that is used on the sleeper, frequently be subjected under the high-speed overload load impact effect of locomotive traction for a long time, its spring easily produces tired and deforms, cause the buckle press of spring to descend rapidly, cause rail creeping, gauge is out of control, even spring occurs and come off and lose, and influences the normal operation of railway.For guaranteeing traffic safety, must often change spring and track gauge block in the maintenance, exist material consumption many, the expense height, engineering quantity is big.CN2321806Y discloses a kind of self-locking rail elastic bar fastener, the step-like recess that is along its axis is arranged on its spring, the step-like boss that is along its axis is arranged in the jack of Button Block, be intended to solve existing rail elastic bar fastener and be easy to the problem of becoming flexible, come off, losing, but the problem that elastic-strip pressure is descended is not effectively solved yet.
The purpose of this utility model is to provide a kind of convenient adjustable rail of buckle press self-locking elastic bar fastener of adjusting buckle press and effectively preventing the spring loose or dislocation.
The utility model is to realize above-mentioned purpose like this.The plugging position of spring and Button Block is shaped on anti-loose structure, is shaped on the oblique shape boss that is cone at the inserted terminal of spring along axis, is shaped on the groove that matches with the spring inserted terminal along axis in the jack of Button Block.The buckle press adjusting device is combined by track gauge block and regulating block, and regulating block places between track gauge block and the track below, is shaped on reference column on regulating block, then is shaped on the hole of matching with reference column on the regulating block on the track gauge block.
The utlity model has simple in structure, the characteristics of the easy to adjust and reliable operation of buckle press.Self-locking elastic bar fastener reliable operation can prevent effectively that loose or dislocation from use appearring in spring; The needs of the visual buckle press of buckle press adjusting device make up, and are easy to construction and save material, are applicable to the installation of standard gage railway ew line and the transformation of old line.
Accompanying drawing is a cross-sectional view of the present utility model.Give being embedded with Button Block 6 on the sleeper 2, the bottom of rail 1 is equipped with regulating block 3 and track gauge block 4, and self-locking spring 5 has been withheld on its top.
Embodiment of the present utility model is 60Kg/m rail self-locking elastic bar fastener, adopts standard III type elastic bar fastener transformation of the way processing.The inserted terminal of self-locking spring 5 is shaped on the oblique shape boss that is cone, is shaped on groove in the jack of Button Block 6.Track gauge block 4 is furnished with 6 kinds of specifications, and regulating block 3 thickness are 2～3mm.Be shaped on φ 8 cylinders on the regulating block 3, be shaped on the hole of matching on the track gauge block 4, the two all adopts high-strength toughening composition to make.
