Description
Technical Field
The invention belongs to the field of floor structures of rail transit vehicle equipment, and particularly relates to a floor supporting structure.
Background
With the rapid development of rail transit, the requirement for the lightweight of the carriage is higher and higher, and among them, the light high-strength floor becomes the main development trend of the rail transit floor. At present, domestic rail transit floors mainly adopt sandwich structures, for example, high-speed train floors mostly adopt foam sandwich structure floors, and subway floors with higher bearing requirements adopt aluminum honeycomb sandwich structure floors. But the mechanical property of the foam sandwich structure floor is limited, and the later repair difficulty is large; and aluminium honeycomb sandwich structure floor is overweight relatively, and when the heavy object falls from higher department, when exceeding the ability bearing pressure of aluminium honeycomb, causes easily and collapses, hardly restores, does not also possess good sound insulation, the performance of making an uproar simultaneously. In addition, the skin and the middle core layer of the traditional foam and honeycomb sandwich structure floor are formed by a glue joint process, so that the traditional foam and honeycomb sandwich structure floor is easy to delaminate in the using process, the mechanical property is greatly reduced, and finally the material is failed, so that the delamination resistance is poor.
Current floor supporting seat is installed between floor and floor chassis, bonds the aluminum plate of floor supporting seat at aluminium honeycomb floor through the double faced adhesive tape, installs the lower part rubber of floor supporting seat in the middle of the floor chassis simultaneously, plays the vertical load of transmission, and the effect of buffering vibration improves the train and takes the travelling comfort. When the lower rubber is arranged in the middle of the floor underframe, the lower rubber is not enough in design, so that the installation efficiency is low, and the rigidity adjusting capability is limited.
Therefore, the invention needs to provide a floor supporting structure which can effectively adjust the vertical rigidity and is convenient to install, and has great practical significance and economic value.

The vacant part can be arranged at the center of the bottom surface of the support seat body, and can increase and adjust vertical rigidity, increase the free surface of rubber and prolong the fatigue life while being uniformly stressed; two clamping parts can be symmetrically arranged at two ends of the seat body, so that the installation with the inner wall of the clamping part is more convenient, and the efficiency is improved; of course, two modes can be selected to coexist, namely, the middle part and the connecting end are both provided with the empty parts, and in the case, every two empty parts are not communicated, so that the rubber sealing ring can be quickly installed, and the free surface of rubber is increased.
Further, the groove body is one or two of an arch shape, a rectangular shape and a polygonal shape.
Further, the guide part comprises a combination of a straight line section and a guide arc, one end of the guide arc is connected with the straight line section, and the other end of the guide arc is connected with the installation bottom plate. The structure of the guide part can ensure that the supporting seat body is easily arranged in the two clamping parts.
Further, the block portion includes the spacing portion of vertical direction and the horizontal spacing portion that is the angle setting with the spacing portion of vertical direction.
Furthermore, the extending direction of the groove body is parallel to the transverse limiting part of the clamping part of the floor underframe.
Furthermore, the height of the vertical limiting part is larger than the thickness of the cross section of the supporting seat body attached to the vertical limiting part.
Compared with the prior art, the invention has the beneficial effects that:
the floor supporting structure can adjust vertical rigidity on one hand, increase rubber free surface and prolong fatigue life on the other hand by arranging the concave hollow part towards the top surface.
The floor supporting structure of the invention enables the installation of the supporting seat body and the floor underframe to be more convenient through the arrangement of the clearance part on the side surface of the supporting seat body; meanwhile, the vertical rigidity is effectively adjusted by matching the empty phase and the solid phase of the supporting seat body, and a deformation storage space is provided for the supporting seat body deformed by compression; make whole floor bearing structure guarantee to bear under the prerequisite, lightweight more.
According to the floor supporting structure, due to the design of the guide part protruding outwards and the straight line section of the guide part, the floor supporting seat can be vertically pressed into the floor underframe after the bottom rubber deforms in the vertical pressing process. Meanwhile, after the floor underframe is completely pressed in, the rubber deformation is recovered, and the displacement limitation in the horizontal direction and the vertical direction can be realized.
