Abstract
The utility model provides a rail vehicle equipment compartment base board, which meets the requirements for a base board lightweight design and installation stability by riveting reinforced ribbed plates on two sides of a single-layer stainless steel corrugated plate and utilizing a multipoint fastening method for improving safety redundancy and a fixing structure between the base board and an equipment compartment framework. Two ends of the equipment compartment base board are overlapped on the equipment compartment framework. The base board comprises a single-layer corrugated plate, the reinforced ribbed plates are riveted to two sides of the corrugated plate through a plurality of ring-grooved rivets respectively; turnups are arranged on the two sides of each reinforced ribbed board respectively and perpendicular to a corrugation extending direction of the corrugated plate. The stainless steel corrugated plate is utilized as a basic structure to realize the lightweight design, further a ring-grooved rivet structure of strong connection tightness are utilized to connect partial corrugated plates and the reinforced ribbed boards to replace a conventional welding structure with poor fatigue resistance.
Description
Technical field
The utility model is the structural development at the railway vehicle device ceiling board, is applicable to the light-weight design of high-speed track vehicle, belongs to mechanical manufacturing field.
Background technology
Follow the significantly lifting of present domestic main line railway, urban light rail traffic operation speed, proposed higher design standard for vehicle lightweight and safe running performance.
The car cross sill place of existing guideway vehicle is provided with equipment compartment at large, with at the inner auxilliary equipment under wire casing, spool and other cars of establishing of the confined space of equipment compartment, with the stone of avoiding being subjected to occurring in the high-speed cruising process hit, component damage such as freezing.
The guideway vehicle of speed per hour more than 380 kilometers/hour for present domestic place in operation, the structure of equipment compartment and in-use performance, hold the key property of equipment under the car except that satisfying, also requirement can realize lightweight as much as possible, possesses cooresponding anti-seismic performance and prevent safety problems such as getting loose appears in link.
Existing railway vehicle device ceiling board also be far from reaching or meeting above-mentioned design and operating needs.
The utility model content
Railway vehicle device ceiling board described in the utility model, 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 at the multiple spot fastening means of the raising safety redundancy that increases on the base plate and the fixed sturcture between base plate and the equipment compartment skeleton, realize the base plate light-weight design and stability requirement is installed to take into account.
Design goal of the present utility model is, promptly realizes the lightweight structure design of base plate, can reach the safe application performance that carries violent Pneumatic immpacting or the impact of circuit gravel again.
Another design goal is, the safety that satisfies base plate and equipment compartment skeleton hangs, prevent because of high-speed cruising, severe jolt to the stress rupture that the equipment compartment connection structure produces, prevent that getting loose from appearring in base plate, landing.
For realizing above-mentioned design goal, described railway vehicle device ceiling board, its two ends are overlapped in the equipment compartment skeleton.
Mainly include, described base plate includes a single layer corrugated plating, strengthens gusset by several hooked riveting with lock rivet respectively in the corrugated plating both sides;
The dual-side that each strengthens gusset is respectively arranged with flange;
Flange is vertical mutually 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 the face of equipment compartment framework aluminum section bar, and adopt fixedly fastening means of the higher multiple spot of safety redundancy.
Base plate adopts individual layer stainless steel wave card as basic design, has at first realized a kind of light-weight design, and local the employing with the reinforcement gusset of corrugated plating is connected the outstanding hooked riveting with lock rivet structure of tightness once more, abandoned the relatively poor welded structure of conventional fatigue resistance.
The individual layer corrugated plating has comparatively significant rigidity on its corrugated stretch direction, and two side flangings of reinforcement gusset are vertical mutually with the corrugated stretch direction, can increase base plate single-piece rigidity further.
For ease of making and the control working accuracy, described corrugated plating is a monoblock stainless steel sheet of making by single cavity die.
Be further to optimize and improve base plate single-piece rigidity, the flange of described reinforcement gusset both sides is distinguished 2 direction bendings up and down, promptly takes the symmetrical turnup structure of different wrap direction.
Or based on the same design design, the flange of described reinforcement gusset both sides makes progress or bending downwards simultaneously simultaneously, promptly takes the turnup structure in opposite directions of identical wrap direction.
For guaranteeing the stability after base plate is installed to the equipment compartment skeleton, arrangement is comparatively reliably, and the corrugated stretch direction of described corrugated plating is the longitudinal direction along car body, and vertical mutually with the installation direction of equipment compartment skeleton.
The comparatively preferred connection mode of described base plate and equipment compartment skeleton is in the both sides of base plate, by several bolts base plate and equipment compartment skeleton to be carried out fastening installation.
Be installation or removal base plate on the equipment compartment skeleton more easily, can corrugated plating with strengthen gusset bonded assembly sidepiece, be provided with several, screwed screw seats riveted joint by countersunkrivet;
Above-mentioned bolt-through is bolted in the screw seat.
Owing to riveted threaded steel screw seat by countersunkrivet, then can get final product at the enterprising line operate of single face during the installation or removal base plate on the surface of base plate.
When guideway vehicle was runed at a high speed, the connection structure that causes for the decline of reply base plate shock resistance, antifatigue degree and because of severe jolt was damaged problem, can corrugated plating with strengthen gusset bonded assembly sidepiece, be provided with several locating dowel pins.
On base plate, increase locating dowel pin, can when being installed, play base plate the effect of easier location on the one hand, if loosening situation appears in the bolt of gap-bridging device cabin skeleton on the other hand, also can play the maintenance base plate and articulate, increase the booster action that safety is installed by locating dowel pin.
In sum, the utility model railway vehicle device ceiling board has the following advantages and beneficial effect:
1, realized the lightweight structure design of base plate, the operation of running at high speed that helps improving guideway vehicle.
2, base plate self has higher and rigidity, can carry violent pneumatic or circuit gravel and impact, and is safe.
3, the safety that can satisfy with the equipment compartment skeleton hangs, prevent because of high-speed cruising, severe jolt to the stress rupture that the equipment compartment connection structure produces, avoid safety misadventures such as getting loose appears in base plate, landing.
4, the installation of base plate and equipment compartment skeleton, dismounting are more simple and direct, help reducing on-the-spot the manufacturing or the work capacity of maintenance.
