Abstract
The utility model provides a stepped rubber tie plate for a railway switch, which comprises a rectangular rubber sheet which is allocated with a bolt hole, longitudinal plow grooves are respectively arranged on the upper surface and the lower surface of the rubber sheet, the upper plate surface of the rubber plate is designed into a stepped structure whose traverse both sides and central portion are lower, and the groove bottom surface of the plow groove on the lower plate surface is lower than the groove bottom surface of the plow groove on a relative higher plate surface. Compared with the existing plain cushion type rubber tie plate, the utility model has the advantages of excellent elastic property, high self strength and long service span, which is convenient for achieving the desired value of the rigidity of switch zones.
Description
Technical field
The utility model relates to a kind of step rubber mat plate that is used for railway switch.
Background technology
Existing railway switch rubber mat plate generally adopts the flat pattern backing structure of offering longitudinal groove in the top and bottom of rectangular rubber plate, the variation that shape by changing groove and density realize track switch rigidity.But because the rubber mat plate material behavior, the rigidity of adjusting rubber cushion by the shape and the density change of groove is subjected to bigger restriction, particularly under the very low condition of no tiny fragments of stone, coal, etc. track section rigidity requirement, is difficult to realize; Circuit uniform elastic requirement simultaneously can cause backing plate groove specifications and models too much, and it is bigger to increase cost.In addition, in the use of rubber mat plate,, reduce the elasticity of rubber mat plate self, influence the ride comfort of switch area rigidity because the effect of train also can cause the further raising of railway rail pad rigidity.The elasticity of existing flat pattern rubber mat plate and flexible maintenance poor performance, application life is short, is difficult for realizing the desired value of switch area rigidity.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provides the maintenance performance of a kind of low rigidity and rigidity good, and long service life is easy to realize the step rubber mat plate of the composite rigidity desired value in the switch area.
The technical scheme that realizes above-mentioned purpose is: a kind of step rubber mat plate, it includes the rectangular rubber plate of configuration bolt hole, top and bottom at rubber tile are respectively arranged with longitudinal groove, the upper face of its described rubber tile is arranged to the lower staircase structural model of both lateral sides and middle part, and the groove bottom of its low locational groove of plate face is lower than the groove bottom of the groove on the higher relatively plate face.
The technical solution of the utility model also comprises: the described longitudinal groove that is arranged at the rubber tile top and bottom is the trapezoid cross section groove of width of rebate greater than the bottom land width.
The utility model in the certain limit, adopts the bigger groove pattern design of rigidity under rail; Adopt the relatively low stiffness design in the backing plate intermediate location, and make its thickness less than theoretic throat.Track switch is kept than low elasticity, under the heavy situation of macro-axis, the rubber mat plate contact area is increased, improve rigidity and avoid the rail distortion excessive, improve ride comfort.Because lifting surface area reduces,, improve application life so under the situation that realizes reasonable rigidity value, can effectively improve rubber mat plate self intensity.This step rubber mat plate can conveniently be realized the composite rigidity desired value in the switch area.

Fig. 2 is the vertical view of this step rubber mat plate;
Fig. 3 is the I partial enlarged drawing of Fig. 1.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described.
As accompanying drawing, this step rubber mat plate has the rectangular rubber plate 2 that both sides dispose bolt hole 1 respectively, the interlaced longitudinal groove 3 that is respectively arranged with in the top and bottom of rubber tile 2, its rubber tile 2 laterally is divided into three sections L sections and two sections H sections, the upper face of the L section at both sides and middle part is with respect to the low C value of upper face of therebetween H section, form the staircase structural model of backing plate upper face, the groove bottom of the groove 3 on its L section is lower than the groove bottom of the groove 3 on the H section.
The utility model is arranged at the trapezoid cross section groove of the longitudinal groove 3 preferred width of rebate of rubber tile 2 top and bottom greater than the bottom land width.
Step plate face structure of the present utility model also is suitable for the rubber mat plate that protruding block distributes.
Claims (2)
1, a kind of step rubber mat plate, include the rectangular rubber plate (2) of configuration bolt hole (1), on rubber tile and below be respectively arranged with longitudinal groove (3), it is characterized in that: the upper face of described rubber tile (2) is arranged to the lower staircase structural model of both lateral sides and middle part, and the groove bottom of its low locational groove of plate face (3) is lower than the groove bottom of the groove on the higher relatively plate face.
2, step rubber mat plate according to claim 1 is characterized in that: the described longitudinal groove (3) that is arranged at rubber tile (2) top and bottom is the trapezoid cross section groove of width of rebate greater than the bottom land width.
