Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and the utility model is described.
As depicted in figs. 1 and 2, the utility model provides a kind of compression-type Damping fastening, and described compression-type Damping fastening comprises:
Base 1, is arranged on sleeper 20; The base shoulder block 11 that described base 1 has base plate and extends out from described base plate, base shoulder block 11 is spacing to floating backing plate; The number of described base shoulder block is two, and two base shoulder blocks lay respectively at the both sides of described base plate and stretch out vertically upward, thus can be spacing to floating backing plate from both sides;
Floating backing plate 2, is arranged on described base 1, the backing plate sidewall that described floating backing plate 2 has bed piece and extends out from described bed piece 13; Bed piece extends in the horizontal direction, and backing plate sidewall vertically extends;
Lateral displacement restraint layer 3, be folded between described backing plate sidewall and described base shoulder block 11, lateral displacement restraint layer 3 is vertically arranged;
Vertical displacement restraint layer 4, be folded between described bed piece and described base plate 13, vertical displacement restraint layer 4 is horizontally disposed with;
First set bolt 7, is fastened on base 1 on sleeper 20;
Second set bolt 9, is fixed on rail 30 on described floating backing plate 2 by elastic device 10.
Described lateral displacement restraint layer 3 and vertical displacement constraint 4 floating backing plate 2 is floating or separate from described base 1, to play the effect of buffering or vibration isolation to rail; Because lateral displacement restraint layer 3 is mutually vertical with the constraint direction of vertical displacement constraint 4, therefore, two constraint impacts are each other lower, fastener can be allowed to carry out independent value at the rigidity value of all directions and damping value according to actual needs, thus realize high-grade vibration vibration isolation amount under guarantee travel safety.
Further, described base 1 is also provided with the positive stop lug boss 12 limiting floating backing plate length travel, described positive stop lug boss 12 is protruding upward from described base plate 13.In this lug boss position, floating backing plate 2 has dug corresponding groove, can limit the length travel of floating backing plate 2 along rail after boss and groove fit.
Further, described first set bolt 7 is stud; First 71 (first nut) of described stud, between described bed piece and described base plate, base 1 through base plate, thus is fastened on sleeper 20 by the screw rod of stud; Second 72 (second nut) of described stud be positioned at described first 71 top and above the bed piece being pushed against described floating backing plate by spring 75, adopt stud can firm banking and floating backing plate preferably, and by bolt, packing ring and spring, precompressed is carried out to floating backing plate 2.
Further, described lateral displacement restraint layer 3 is elastomeric material, is connected with base by vulcanization process with floating backing plate.At this moment, this rubber has the mechanical characteristic of resistance to compression not shearing resistance, adds face effect of restraint, makes floating backing plate 2 can be subject to very big constraint in lateral displacement and flip angle, and the motion effects of lateral displacement constraint rubber pad to floating backing plate 2 vertical direction is less.
Lateral displacement restraint layer 3 also can have certain degree of hardness, elastic layer that friction factor is low and wear-resisting for surface, and this bed course is only fixed with base shoulder block 11 and is connected.Under floating backing plate 2 lateral turnover of restriction and displacement, do not limit the sliding relative movement of its vertical direction.
Further, between described floating backing plate 2 and stud, there is clearance space.Have larger radial clearance between stud 7 and floating backing plate 2, the two can not directly contact, and prevents floating backing plate 2 from vibration processes, producing larger cross shear to stud.
Further, described elastic pressed piece 10 is spring, can elastic compression rail 30.Second set bolt 9 is such as the T-shaped bolt of fastening spring.
Further, described compression-type Damping fastening also comprises: be arranged on the sleeper height adjusting cushion plate 5 between described base plate 13 and described sleeper 20, to play the effect of heightening.
Further, described vertical displacement restraint layer 4 is rubber pad, to play the effect of vibration isolation.
Further, the material model of described vertical displacement restraint layer 4, thickness and space structures form, determine anti-vibration performance, suitable material model can be selected according to parameter requirements, thickness and space structures form, selection vertical displacement restraint layer 4 is solid rectangular rubber plate or the backing plate be made up of multiple rubber cone or is the rubber mat plate with hole slot.
The Damping fastening that the utility model provides, be such as compression-type Damping fastening JT-YS-01 or be applicable to compression-type Damping fastening JT-YS-01, high-grade anti-vibration performance can be realized under guarantee travel safety, solve train through the out-of-date vibration pollution to surrounding enviroment.
The foregoing is only the schematic detailed description of the invention of the utility model, and be not used to limit scope of the present utility model.For each ingredient of the present utility model can mutually combine under the condition of not conflicting; any those skilled in the art; equivalent variations done under the prerequisite not departing from design of the present utility model and principle and amendment, all should belong to the scope of the utility model protection.
