Abstract
The invention discloses a base plate of an equipment compartment for a railway vehicle. A basic structure that reinforcing rib plates are pivoted on two sides of a single-layer stainless steel corrugated plate is adopted, and the requirements of the design of light weight and installation stability of the base plate are met by adding a multi-point fastening mode which improves safety redundancy on the base plated and by a fixing structure between the base plate and a framework of the equipment compartment. Two ends of the base plate of the equipment compartment are overlapped on the framework of the equipment compartment. The base plate comprises the single-layer corrugated plate; the two sides of the corrugated plate are pivoted with the reinforcing rib plates through a plurality of circular groove rivets respectively; and two sides of each reinforcing rib plate are provided with flangings which are perpendicular to the corrugation extending direction of the corrugated plate. According to the base plate, the single-layer stainless steel corrugated plate is used as a basic structure, so that the design of light weight is realized, the circular groove rivet pivoting structure which is obvious in connection fastening performance is adopted by the local part of the corrugated plate and the reinforcing ribs, and the conventional welding structure which is low in fatigue resistance is eliminated.
Description
Technical field
The present invention be directed to the structural development of rail vehicle equipment compartment base board, be applicable to the light-weight design of high speed railway car, belong to mechanical manufacturing field.
Background technology
With the significantly lifting of current domestic main line railway, urban light rail traffic operation speed, higher design standard is proposed for vehicle lightweight and safe running performance.
The car cross sill place of existing guideway vehicle is provided with equipment compartment at large, with equipment under additionally arranging wire casing, spool and other cars in the confined space inside of equipment compartment, the component damage such as to hit, freezing to avoid the stone being subject to occurring in high-speed cruising process.
For the guideway vehicle of the speed per hour more than 380 kilometers/hour of domestic place in operation at present, the structure of equipment compartment and in-use performance, except the key property of equipment under satisfied accommodation car, also requirement can realize lightweight as much as possible, possesses suitable anti-seismic performance and prevent link from occurring safety problems such as getting loose.
Existing rail vehicle equipment compartment base board is also far from reaching or meet above-mentioned designing and employing requirement.
Summary of the invention
Rail vehicle equipment compartment base board of the present invention, it is to solve above-mentioned technological deficiency and problem and takes to strengthen in the riveted joint of individual layer stainless steel wave card both sides the basic structure of gusset, by the Multi-point fastening mode of raising safety redundancy that increases on base plate and the fixed sturcture between base plate and equipment compartment skeleton, realize base plate light-weight design to take into account and stability requirement is installed.
Not only the object of the invention is to, realize the lightweight structure design of base plate, but also the safe application performance that the violent Pneumatic immpacting of carrying or circuit gravel impact can be reached.
Another goal of the invention is, meets the safety suspension of base plate and equipment compartment skeleton, prevents the stress rupture because high-speed cruising, severe jolt produce equipment compartment connection structure, prevents base plate from occurring getting loose, landing.
For achieving the above object, described rail vehicle equipment compartment base board, its two ends are overlapped in equipment compartment skeleton.
Mainly include, described base plate includes the corrugated plating of an individual layer, strengthens gusset in corrugated plating both sides respectively by several hooked riveting with lock rivet;
Each strengthens the dual-side of gusset, is respectively arranged with flange;
Flange is mutually vertical with the corrugated stretch direction of corrugated plating.
As above-mentioned basic scheme feature, the installation of described base plate cooperating equipment cabin skeleton, its two ends are overlapped in stretching out on face of equipment compartment framework aluminum section bar, and adopt the more much higher point of safety redundancy to fix fastening means.
Base plate adopts individual layer stainless steel wave card as basic design, first achieves a kind of light-weight design, and corrugated plating local adopts with reinforcement gusset and is connected the outstanding hooked riveting with lock rivet structure of tightness again, abandons the welded structure that conventional fatigue resistance is poor.
Individual layer corrugated plating has comparatively significant rigidity on its corrugated stretch direction, and two side flangings strengthening gusset are mutually vertical with corrugated stretch direction, can increase the rigidity of base plate entirety further.
For ease of manufacturing and controlled working precision, described corrugated plating is the monoblock stainless steel sheet made by single cavity die.
For optimizing and improve the rigidity of base plate entirety further, the flange of described reinforcement gusset both sides, respectively to upper and lower 2 direction bendings, namely takes the symmetrical turnup structure of different wrap direction.
Or based on same design design, the flange of described reinforcement gusset both sides, simultaneously upwards or simultaneously downward bending, namely take the turnup structure in opposite directions of identical wrap direction.
For ensureing that base plate is installed to the stability after equipment compartment skeleton, comparatively reliably arrangement is, the corrugated stretch direction of described corrugated plating is the longitudinal direction along car body, and mutually vertical with the installation direction of equipment compartment skeleton.
The comparatively preferred connection mode of described base plate and equipment compartment skeleton, in the both sides of base plate, by several bolt, base plate and equipment compartment skeleton is carried out fastening installation.
For installing or removing base plate more easily on equipment compartment skeleton, at corrugated plating and the sidepiece strengthening link of boards, several that riveted by countersunkrivet, screwed screw seat can be provided with;
Above-mentioned bolt-through is bolted in screw seat.
Owing to having riveted threaded steel screw seat on the surface of base plate by countersunkrivet, then can at the enterprising line operate of one side during installation or removal base plate.
When guideway vehicle is runed at a high speed, for the decline of the shock resistance of reply base plate, antifatigue degree and the connection structure that causes because of severe jolt damage problem, at corrugated plating and the sidepiece strengthening link of boards, several locating dowel pin can be provided with.
Base plate increases locating dowel pin, the effect of more easily locating can be played on the one hand when mounting base, if the situation that loosens appears in the bolt of gap-bridging device cabin skeleton on the other hand, also play the mounting of maintenance base plate by locating dowel pin, increase the booster action installing safety.
In sum, rail vehicle equipment compartment base board of the present invention has the following advantages and beneficial effect:
1, achieve the lightweight structure design of base plate, be conducive to the operation of running at high speed improving guideway vehicle.
2, base plate self has higher and rigidity, and can carry violent pneumatic or circuit gravel and impact, safety is high.
3, the safety suspension with equipment compartment skeleton can be met, prevent the stress rupture because high-speed cruising, severe jolt produce equipment compartment connection structure, avoid base plate to occur getting loose, the safety misadventure such as landing.
4, base plate and equipment compartment skeleton installation, dismantle more simple and direct, be conducive to the work capacity reducing making in site or maintenance.
