Abstract

The utility model relates to an integral type floating vibration-reducing floor for high-speed trains, comprising the floor, wherein a plurality of vibration-reducing pads are arranged on the underframe crossbeam of a car body; the floor is overlapped on the vibration-reducing pads; and the periphery of the floor is hermetically connected with the car body. According to the utility model, the floor is installed by adopting a mode of direct overlap and no connection fixing point exists between the floor and the car body; and compared with a floor installed by adopting a mode in general use at present, the floor has better sound-insulating vibration-reducing effect and energy-absorbing vibration-resisting performance, so that the noise in the car is greatly reduced and the passenger comfort is improved.

Description

The high speed train integral type vibration damping floor of floating
Technical field
The utility model relates to a kind of rolling stock equipment, and particularly a kind of high speed train integral type vibration damping floor of floating belongs to the rolling stock equipment technical field.
Background technology
Existing high speed train floor is commonly the single laminated structure of surface coverage floor cloth, through support fixation on the car body corrugated floor.Often this floor panel structure has its deficiency: because there is the constraint that is fixedly connected between floor-support-car body underframe, major part just is delivered to the guest room through them from the vibration between high-speed cruising wheel and the rail, and the traveling comfort that car load is taken is greatly diminished.
Summary of the invention
The utility model main purpose is to address the above problem and is not enough, provides a kind of high speed train integral type rational in infrastructure, that have favorable damping, soundproof effect unsteady vibration damping floor.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of high speed train integral type vibration damping floor of floating comprises the floor, and the car body body transom is provided with several shock pads, and said floor is taken and put on said shock pad, is tightly connected around the said floor and between the car body.
Further, said shock pad is the mushroom-shaped rubber damper.
Further, on said crossbeam, be designed with several knock holees, the bottom of said mushroom-shaped rubber damper has the registration mast that stretches out downwards, and said registration mast inserts and realizes the fixing of said shock pad in the said knock hole.
Further, between said mushroom-shaped rubber damper and said car body body transom, be provided with the bearing cap shim that is used to adjust height.
Further, said floor realizes sealing through rubber weather strip and sealant all around.
Further, the side on said floor has the frame section bar, and said frame section bar is the arcuate structure that is upturned.
Further, said floor is a compoiste wood floor, from top to bottom by floor cloth, veneer sheet, acoustic, metal sheet is bonding forms, and in the middle of said floor, is compounded with the beams of metal of multi-ribbon C shape groove.
Further, said metal sheet is stainless steel sheet or aluminium sheet.
Further, the beams of metal of said band C shape groove is an aluminium alloy extrusions.
Further, the beams of metal and the compoiste wood floor of said band C shape groove are pegged graft and are adhesively fixed.
Content to sum up, the high speed train integral type that the utility model the provided vibration damping floor of floating is adopted and is directly taken the mode of putting and install; With no any attachment point that is connected between the car body; Floor mounting means with generally adopting is at present compared, and has better sound insulation effectiveness in vibration suppression and energy-absorbing resistance to shock, and the interior noise of car is reduced greatly; Satisfy speed per hour more than or equal to 200 kilometers/hour operating needss that wait high speed train, also can improve passenger comfort simultaneously.
Description of drawings
Fig. 1 the utility model structural representation.
As shown in Figure 1, floor 1, crossbeam 2, shock pad 3, registration mast 4, bearing cap shim 5, frame section bar 6, rubber weather strip 7, floor cloth 8, veneer sheet 9, acoustic 10, metal sheet 11, beams of metal 12.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1; The described high speed train integral type of the utility model vibration damping floor of floating comprises floor 1, on many car body body transoms 2, evenly is provided with several shock pads 3; After in floor 1 integral hoisting to the car; Directly take and put on several shock pads 3, no any attachment point that is connected between floor 1 and the car body, the position that is provided with of shock pad 3 can be provided with according to the stressed distribution situation on floor 1.In this mounting structure; Crossbeam 2 not only has enough strength support floors 1; Can also effective attenuation come from the vibration amplitude of equipment under car body, the car, the vibration of equipment can directly not be passed in the car through being rigidly connected under car body, the car, guarantees the stationarity and the traveling comfort of vehicle interior.
In the present embodiment, the shock pad 3 preferred mushroom-shaped rubber dampers that adopt, mushroom-shaped is up-small and down-big shape; This shape is after the weight distortion of bearing floor 1; Can increase the area of contact on shock pad 3 and floor 1, improve the reliability and the support strength of this shock pad 3, play good buffer action simultaneously; Can strengthen the sound insulation effectiveness in vibration suppression and the energy-absorbing resistance to shock of shock pad 3 significantly, satisfy the operating needs of high-speed track vehicle.
The bottom of mushroom-shaped rubber damper 3 has the cylindrical registration mast 4 that stretches out downwards; Registration mast 4 is a component part of mushroom-shaped rubber damper 3; On crossbeam 1, be designed with several knock holees (not indicating among the figure), registration mast 4 inserts and realizes the spacing and fixing of shock pad 3 in the knock hole.
Between mushroom-shaped rubber damper 3 and crossbeam 2, also be provided with the bearing cap shim 5 that is used to adjust height, when floor 1 is installed, be used to adjust the planeness on floor 1.
The side on floor 1 has frame section bar 6; Frame section bar 6 is the arcuate structure that is upturned; Realize being tightly connected through rubber weather strip 7 and sealant between frame section bar 6 and the car body, avoid on the floor 1 water or foreign material etc. from around the gap enter in the car body of 1 below, floor.
In this enforcement row; Compoiste wood floor is adopted on floor 1; From top to bottom by floor cloth 8, veneer sheet 9, acoustic 10, damp-proof metal sheet 11 bonding the forming of sound insulation; Be compounded with the beams of metal 12 of many elongated band C shape grooves in the middle of 1 on the floor, the beams of metal 12 of band C shape groove is used for fixing seat, the sofa interior equipment of waiting for bus.The beams of metal 12 of band C shape groove is pegged graft and is adhesively fixed with floor 1.Bond together through special-purpose adhesive between floor cloth 8 and the veneer sheet 9, be adhesively fixed through acoustic 10 between veneer sheet 9 and the metal sheet 11, this floor 1 structure has good anti-soak properties.
Wherein, for guaranteeing the bulk strength on floor 1, metal sheet 11 adopts stainless steel sheet or aluminium sheet, and the beams of metal 12 of band C shape groove adopts aluminium alloy extrusions.
As stated, in conjunction with accompanying drawing and the given scheme content of embodiment, can derive the similar techniques scheme.In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
