Wherein, 1---heelpiece; 1.1---damper unit; The non-damper unit of 1.2---; 2---side pad; 3---designs tread face; 4---substrate; 5---checks cylinder; 6---line midline; 7---central row ditch; 8---supporting steel plate.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
As shown in Figure 1, the utility model provides a kind of and is applied to non-fragment orbit there being the vibration insulating system under water condition with excellent effectiveness in vibration suppression, comprises heelpiece 1 and side pad 2;
Side pad 2 comprises left side pad and right side pad, and left side pad is arranged at the left surface of the track bed board of non-fragment orbit; Right side pad is arranged at the right flank of the track bed board of non-fragment orbit; During specific implementation, left side pad and right side pad are pasted on respectively in left side wall and right-side wall, by the mode of concreting, make left side pad between left side wall and the left surface of track bed board; Make right side pad between right-side wall and the right flank of track bed board.
Left side pad or right side pad all adopt the macromolecular material having elasticity and damping concurrently, and such as, be polyurethane high molecule material or rubber etc., its effect is vibration damping and elastomeric isolation.And, because side pad 2 is arranged at the side of track bed board, the vibration force be subject to is less, therefore, damping property is required it is not very high, according to the actual requirements, both full closed pore expanded material can be adopted, also can adopt opening and closing hole combination construction material, its thickness range, also lower than heelpiece, is generally 8mm-30mm.
Heelpiece 1 is arranged at the below of track bed board, and is positioned at substrate; The left side of heelpiece 1 and the bottom surface close contact of left side pad, the right side of heelpiece 1 and the bottom surface close contact of right side pad; In addition, for anti-sealing or foreign material enter into heelpiece, reduce effectiveness in vibration suppression, in the utility model, the contact position of the left side of heelpiece 1 and the bottom surface of left side pad seals, such as, by rubber belt sealing, or, by filling viscose glue sealing to intersection location; Same, the right side of heelpiece 1 and the underrun adhesive tape of right side pad or the mode of filling viscose glue seal.
In addition, because heelpiece 1 is arranged at the below of track bed board, compared with the pad of side, be subject to larger vibration force, therefore, the damping property of heelpiece directly have influence on train by time the magnitude of vibrations that produces.
In the utility model, Fine design is carried out to the structure of heelpiece, both there is excellent damping property, there is again excellent support performance, also have that structure is simple, advantage simply and easily of constructing.Concrete, heelpiece is that the damper unit 1.1 of bar shape and non-damper unit 1.2 are spaced and form by direction along ng a path; Such as, press direction from left to right, lay non-damper unit, damper unit, non-damper unit successively ...According to the width of concrete technology Demand Design damper unit and non-damper unit.Damper unit 1.1 act as vibration damping, adopting and have the macromolecular material of elasticity and damping concurrently, such as, is polyurethane high molecule material or rubber; Thickness range 12.5mm-50mm; Acting as of non-damper unit 1.2 provides support and fills, and adopting the macromolecular material with plastic strain, such as, is plastics or polyester sheet, thickness range 12.5mm-50mm.
Wherein, damper unit 1.1 and non-damper unit 1.2 are full closed pore expanded material, solve in prior art, because cushion blocking is opening and closing hole combination construction, easily make water enter into perforate and the problem causing effectiveness in vibration suppression to decay.
In installation process, first, after laying damper unit and non-damper unit, the spaced slot position of damper unit and non-damper unit needs sealing, such as, adopt the mode of adhesive tape or filling viscose glue to seal, thus make the spaced slot position of damper unit 1.1 and non-damper unit 1.2 can not fall into dust foreign material, as: enter the foreign material such as the grains of sand or a large amount of concrete; And then build track bed.Due to damper unit and non-damper unit closely connected coincide, further increase effectiveness in vibration suppression.
What the utility model provided is having the vibration insulating system under water condition with excellent effectiveness in vibration suppression, and feature is as follows:
(1) heelpiece adopts full closed pore expanded material, solve in prior art, because cushion blocking is opening and closing hole combination construction, easily make water enter into perforate and the problem causing effectiveness in vibration suppression to decay, therefore, ensure that the effectiveness in vibration suppression of vibration insulating system under water environment;
(2) heelpiece is slabbed construction, upper surface contacts completely with track bed board, and area is substantially identical with the floor space of track bed board, and soffit contacts completely with track substrate, achieve evenly distributed load, time stressed, realized the decay of vibrational energy by the elasticity of self.And be the decay relying on the vertebral deformation of soffit to realize vibrational energy with the elastomeric material of centrum, the existence because of centrum makes the contact area of itself and substrate relatively little, and local pressure is larger.In the environment having water, water occupies the deformation space of centrum and causes effectiveness in vibration suppression partially or completely to lose; Therefore, the relevant deficiency that the elastomeric material that the invention solves traditional centrum has;
(3) damper unit of heelpiece and non-damper unit interval are arranged, and have both had good support force, can have again excellent effectiveness in vibration suppression, and, also there is the simple advantage of construction; In addition, damper unit and non-damper unit are that bar shaped is arranged, compare the full paving mode generally adopted at present, have less lifting surface area, can realize more excellent effectiveness in vibration suppression.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
