The utility model discloses a trapezoidal nylon baffle seat for railways, which is installed in a rail bearing groove of a concrete sleeper, and comprises two trapezoidal seats connected together by an extendable and shortened connecting plate at the bottom. The upper end of the trapezoidal seat is used to install the rail, and the two trapezoidal seats are fixed on the concrete sleeper by hexagon screws and fastened by insulating special-shaped splints. The bottom edge of the trapezoidal seat is provided with a raised rib. An arc-shaped locating groove is provided on the knitting edge of the insulating special-shaped splint, one side of the insulating special-shaped splint is limited by the retaining edge, and the other side of the insulating special-shaped splint is clamped in the locating groove. Compared with the common nylon baffle seat, the utility model increases the force bearing area with the concrete sleeper, reduces the impact force of the lateral force generated when the train passes on the shoulder of the rail bearing groove of the concrete sleeper, and is beneficial to improve the service life of the concrete sleeper and driving safety.
Description
Technical field
The utility model relates to railroad track accessories field more particularly to a kind of trapezoidal nylon baffle seats of railway.
Background technique
Railway is fixed on the two sides of the concrete crosstie of rail two sides with nylon baffle seat, plays fastening rail, keeps and adjusts
The important function for saving two rail spacing, in train operation, apron block can bear the cross force that train is given and by the transverse direction
Power passes to apron block and sleeper shoulder block.
The contact surface of existing rail and concrete crosstie is small, powerful cross force can be generated when train passes through, to concrete
The rail support groove shoulder block of pillow generates stronger impact force, so as to shorten the service life of concrete crosstie, reduces travel safety；It is existing
Nylon baffle seat only pass through screw and be attached with concrete crosstie, this connection type is easy to happen pine after long-term use
It is dynamic, and torque resistant ability is poor, does not have the effect of good fastening rail.
Summary of the invention
In view of this, the present invention provides a kind of trapezoidal nylon baffle seats of railway, can increase concrete crosstie and steel
The forced area of rail is conducive to the service life and traffic safety that improve concrete crosstie.
The utility model is solved the above problems by following technological means:
The trapezoidal nylon baffle seat of the railway of the utility model, is installed in the rail support groove of concrete crosstie, including pass through bottom
Two trapezoid seats that the connecting plate that is extending and shortening in portion links together, the upper end of the connecting plate are used to install rail,
Two trapezoid seats are fixed on concrete crosstie by hex screw, and are fastened by the compromise joint that insulate, the ladder
The bottom edge edge of shape seat is equipped with the rib of protrusion, and the edge of delimiting the organizational structure of the trapezoid seat is equipped with the locating slot of arc, and the insulation is different
The side of clevis plate is limited by the rib, and the other side of the insulation compromise joint is stuck in the locating slot.
Preferably, the connecting plate is elastic cushion.
Preferably, the connecting plate is mechanical type expansion plate.
The trapezoidal nylon baffle seat of the railway of the utility model connects two trapezoid seats by connecting plate to bear rail
Weight, and concrete crosstie will be passed to after the dispersion of the weight of rail, it is increased and concrete crosstie compared to common nylon apron block
Forced area, reduce train by when the cross force that generates to the impact force of the rail support groove shoulder block of concrete crosstie, be conducive to mention
The service life of high concrete pillow and traffic safety；And it can be convenient for rail being put into two ladders by connecting plate that is extending and shortening
Between shape seat and rail is clamped, then is fixed by the hex screw, stabilization is firmly installed, there is good torque resistant energy
Power extends service life.

Device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this is practical
Novel limitation.
The utility model is described in detail below with reference to attached drawing: railway described in the present embodiment is kept off with trapezoidal nylon
Panel seat is installed in the rail support groove of concrete crosstie 1, including being linked together by the extending of bottom and the connecting plate 3 shortened
Two trapezoid seats 4, the upper end of the connecting plate 3 passes through the fixation of hex screw 5 for installing rail 2, two trapezoid seats 4
It is fastened on concrete crosstie 1, and by the compromise joint 6 that insulate, the bottom edge edge of the trapezoid seat 4 is equipped with the rib of protrusion
7, the edge of delimiting the organizational structure of the trapezoid seat 4 is equipped with the locating slot 8 of arc, and the side of the insulation compromise joint 6 passes through the rib 7
It is limited, the other side of the insulation compromise joint 6 is stuck in the locating slot 8.
The trapezoidal nylon baffle seat of railway described in the present embodiment connects two trapezoid seats 4 by connecting plate 3 to bear steel
The weight of rail 2, and concrete crosstie 1 will be passed to after the dispersion of the weight of rail 2, it is increased compared to common nylon apron block and coagulation
The forced area of soil pillow 1, reduce train by when the cross force that generates to the impact force of the rail support groove shoulder block of concrete crosstie 1,
Be conducive to improve service life and the traffic safety of concrete crosstie 1；And it can be convenient for by connecting plate 3 that is extending and shortening by rail
2 are put between two trapezoid seats 4 and clamp rail 2, then are fixed by the hex screw 5, firmly install stabilization, have
Good torque resistant ability extends service life.
As an embodiment of the present embodiment, the connecting plate 3 is elastic cushion.
As the another embodiment of the present embodiment, the connecting plate 3 is mechanical type expansion plate.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
