Abstract
The utility model discloses a steel rail fastener, which comprises an iron base plate, an anchor bolt and a buckling assembly, wherein the anchor bolt is connected with a sleeper to fix the iron base plate on the sleeper; because the two ends of the spring are propped against the sleeper and the end parts of the anchoring bolt, and the spring passes through the through hole on the iron backing plate, the spring can not deform when the iron backing plate floats, so that the propping force of the bolt is kept unchanged all the time, and the anchoring bolt has a good anti-loosening effect.
Description
Technical Field
The utility model relates to the field of rail transit, in particular to a steel rail vibration reduction fastener.
Background
With the development of urban rail transit, the functions of the buckle are required to be high, and particularly, the buckle is required to be high in criticism for vibration generated when a train passes through the peripheral circuits of ancient buildings, laboratories and scientific research institutions. In order to enable the fastener to have certain vibration reduction performance, the vertical rigidity of the fastener is generally reduced, so that a certain vertical displacement can be generated by the steel rail when a train passes by, vibration is buffered, vibration energy is absorbed, and riding comfort is improved. The fastener is mainly fastened and installed by the implementation of an anchor bolt on a sleeper, because an iron backing plate can float when a train passes through, the iron backing plate is caused to impact the anchor bolt, therefore, the anti-loosening treatment of the anchor bolt is very important, the traditional method is to adopt an anti-loosening gasket to carry out anti-loosening treatment on the anchor bolt, and a structure for realizing anti-loosening by adopting a spring is also disclosed in China patent with a publication number of CN203700882U, such as a track buckle fastener with an anti-loosening structure, the spring is sleeved on the anchor bolt, two ends of the spring are propped against the upper surface of the iron backing plate and the end part of the anchor bolt to realize anti-loosening treatment on the anchor bolt, but because the iron backing plate can float when the train passes through, the elasticity of the spring can be changed continuously, and the anti-loosening effect on the anchor bolt can be changed, so that the anti-loosening effect is not ideal.
Disclosure of utility model
In order to solve the defects in the prior art, the utility model provides a fastener with good anti-loosening effect on an anchor bolt, and the technical scheme adopted by the utility model is as follows:
The utility model provides a rail fastener, includes iron backing plate, anchor bolt and withhold the assembly, anchor bolt be connected with the sleeper and fix iron backing plate to the sleeper on iron backing plate on be provided with the bullet strip seat and be used for setting up the installation and withhold the assembly, withhold the assembly and withhold and realize fixed and track gauge adjustment to the rail at the rail end iron backing plate and sleeper between be provided with the board backing plate rail and iron backing plate between be provided with the rail backing plate iron backing plate on be provided with the through-hole that supplies anchor bolt to pass anchor bolt on the cover be equipped with the spring of arranging in the through-hole, spring both ends can be propped up respectively and lean on sleeper and anchor bolt end.
Further, the lower plate backing plate is coated on the iron backing plate, a plurality of columnar protrusions are arranged on the surface of the lower plate backing plate opposite to the sleeper, and a pair of rectangular protrusions are arranged at the center of the lower plate backing plate.
Further, the buckling assembly comprises a spring strip, buckling bolts and a gauge block, wherein the spring strip is arranged on a spring strip seat and is fixed through the buckling bolts, and a shoulder for positioning the gauge block is arranged on one side of the spring strip seat close to a steel rail.
By adopting the scheme, as the two ends of the spring are propped against the end parts of the sleeper and the anchor bolt, and the spring passes through the through hole on the iron backing plate, the spring cannot deform when the iron backing plate floats, so that the propping force of the bolt is always kept unchanged, and the anchor bolt has a good anti-loosening effect.

Detailed Description
The fastener shown in fig. 1 to 3 comprises an iron backing plate 1, an anchor bolt 2, a buckling assembly 3, a rail lower backing plate 5 and a plate lower backing plate 4, wherein the buckling assembly 3 shown in fig. 2 comprises elastic strips 3-1, buckling bolts 3-2 and a track gauge block 3-3, an elastic strip seat 1-1 is arranged on the iron backing plate 1, the buckling bolts 3-2 are arranged on the elastic strip seat 1-1 to compress and fix the elastic strips 3-1, a shoulder 1-3 is arranged on one side of the elastic strip seat 1, close to a steel rail, the track gauge block 3-3 is installed and positioned by the shoulder 1-3, the track gauge block 3-3 is compressed on the edge of a rail bottom through the elastic strips 3-1, and the track gauge is adjusted by replacing the track gauge blocks 3-3 with different specifications.
The iron pad plate 1 is provided with the through hole 1-2 through which the anchor bolt 2 passes, as shown in fig. 3, the anchor bolt 2 passes through the through hole 1-2 to be connected with the sleeper to mount the iron pad plate on the sleeper, in order to prevent loosening of the anchor bolt 2, the anchor bolt 2 is sleeved with the spring 6, the spring 6 also passes through the through hole 1-2, and two ends of the spring 6 respectively lean against the sleeper and the end part of the anchor bolt 2 in a state that the anchor bolt 2 is screwed, so that the iron pad plate 1 can float when a train passes through, but the spring 6 cannot always keep the jacking force of the anchor bolt 2 unchanged under the influence of the floating of the iron pad plate 1, and therefore the anchor bolt 2 has a better loosening preventing effect.
In order to effectively avoid stray current corrosion of the iron pad 1, as shown in fig. 4, the lower pad 4 is formed into a whole with the iron pad 1 through a vulcanization process and is coated on the periphery of the iron pad 1, and in order to provide a better vibration reduction effect, a group of columnar protrusions 4-1 are arranged on the surface of the lower pad 4 opposite to the sleeper, and a pair of rectangular protrusions 4-2 are arranged at the center of the lower pad 4 to improve rigidity, so that the lower pad 4 has higher elasticity and more stable support.
