Abstract
The utility model belongs to the technical field of railway fitting devices, particularly discloses a rail fastener. The utility model is mainly characterized in that the utility model comprises a bottom plate, and a blocking shoulder is installed on the bottom plate; the blocking shoulder is connected with a lateral plate carrier frame of which the top end is provided with a rubber supporting wedge block, and end surface radian of the rubber supporting wedge block is inosculated with the side face radian of a steel rail. When trains pass through, only the steel rail of the rail fastener of the utility model has obvious deformation and vibration, without causing braided waviness due to resonance vibration between trains and steel rails; the utility model avoids noises caused by large-sized moving parts due to vibration and also has the advantage of convenient installation, overhaul and maintenance.
Description
Technical field
The utility model belongs to railway casting device technique field, relates in particular to a kind of railway fastener.
Background technology
At present, railway construction in China is maked rapid progress, and total kilometrage has ranked the prostatitis, countries in the world.In the city, ground rail and subterranean railway are interspersed, and for reducing the influence to railway resident along the line, just need carry out vibration and noise reducing to railway and handle.It is current that what adopt is that rubber mat plate is set under rail, track gauge block is set on rubber mat plate and compresses spring, though this mode can play certain effect, but its lateral deformation is big, when travelling in the city, train need slow down, and, be unfavorable for check and safeguard because rubber mat plate under rail, is observed and inspected very inconveniently.
The utility model content
The purpose of this utility model just provides that a kind of effect of vibration and noise reduction is good, repair and maintenance railway fastener easily.
The technical solution adopted in the utility model is: comprise base plate, on the described base plate shoulder block is installed, described shoulder block is connected with the side plate carriage that the top is provided with the rubber voussoir, and the end face radian of described rubber voussoir and the side radian of rail match.
Its additional technical feature comprises:
Described shoulder block and base plate are movable the installation, and described shoulder block is symmetry is installed on base plate two, is provided with locking wedge block and movable voussoir between shoulder block and the side plate carriage, and locking wedge block fixes by locking spring and shoulder block;
The contact surface of described shoulder block and locking wedge block, movable voussoir is a zigzag, and the contact surface of locking wedge block, movable voussoir and shoulder block also is a zigzag;
Described base plate is provided with cushion pad;
Described cushion pad is provided with the adjustment backing plate;
Described base plate is arranged with height adjusting cushion plate.
Railway fastener provided by the utility model compared with prior art has the following advantages: one, two shoulder blocks of symmetry pass through locking wedge block, movable voussoir makes the rubber voussoir on side plate carriage top be close to the rail two sides, and the end face radian of rubber voussoir and the side radian of rail match, fastener holds " V " type to be stepped up rail from the rail both sides, make this fastener have lower vertical dynamic rate and low longitudinal rigidity, not only can well absorb vehicle by the time vibration that produces, and make do not have heavily stressed transmission between rail and the parts below it, reduced longitudinal deformation.When train passes through, have only rail that tangible distortion and vibration are arranged, can not introduce the percent ripple that resonates and brought between vehicle and the rail, and the noise of avoiding large-scale moving component to produce because of vibration.Its two, shoulder block is movable the installation, and cushion pad is set, adjusts backing plate, height adjusting cushion plate, makes this fastener have very wide tuning range, can adapt to highly different rail, and easy for installation, the scope of application is very wide.Its three, fastener be installed in the where there is light, repair and maintenance is very convenient.
Description of drawings
Accompanying drawing is the structural representation of the utility model railway fastener.
The specific embodiment
Be described further below in conjunction with the structure of the drawings and specific embodiments railway fastener provided by the utility model.
As shown in the figure, railway fastener provided by the utility model comprises base plate 1, on base plate 1, be symmetrically installed with two movable shoulder blocks 2, movable shoulder block 2 is connected with side plate carriage 3, there is rubber voussoir 4 on the top of side plate carriage 3, the radian of the radian of the end face 41 of rubber voussoir 4 and the side 51 of rail 5 matches, between movable shoulder block 2 and the side plate carriage 3 locking wedge block 6 and movable voussoir 7 are arranged, locking wedge block 6 fixes with movable shoulder block 2 by locking spring 8, movable shoulder block 2 and locking wedge block 6, the contact surface 21 of movable voussoir 7 is a zigzag, locking wedge block 6, the contact surface 61 of movable voussoir 7 and movable shoulder block 2,71 also is zigzag, cushion pad 9 is arranged on the base plate 1, below the adjustment backing plate 10, base plate 1 height adjusting cushion plate 11 is arranged.
During use, below first the general height adjusting cushion plate 11 is arranged, there is the base plate 1 of cushion pad 9, adjustment backing plate 10 to be arranged on below the rail 5 above, adjusting activity shoulder block 2 then, make the end face 41 of the rubber voussoir 4 on side plate carriage 3 tops be close to the side 51 of rail 5, regulate locking wedge block 6, the moving voussoir 7 of words again and locking wedge block 5 is fixed with movable shoulder block 2 by locking spring 8, movable shoulder block 2 is fixed with base plate 1 get final product at last.
