Description
Technical field
The present invention relates to body construction technical field, be specifically related to a kind of city rail stainless steel vihicle ceiling section structure.
Background technology
The ceiling steel structure of current city rail stainless steel vihicle primarily of the as a whole ceiling structure of the parts assembly welding such as the beam that winds up, camber beam, corrugated plating of air-conditioning platform, pantograph platform and ceiling, as shown in Figure 1.At the top, position of air-conditioning platform and pantograph platform lower than ripple top panel area, such ceiling structure requires higher to parts assembly welding technique, weld the bad control of amount of deflection of rear whole ceiling, at car load assembly welding space-time leveling platform, Altitude control between pantograph mesa base and vehicle floor is bad, unstable on diff-H.In addition because in-built middle apex distance is from the distant steel structure smallclothes needing secondary transition of ceiling corrugated plating place camber beam, the quantity of these type of smallclothes design is more, and complex-shaped welding capacity is large.This type of weldment is unfavorable for vehicle loss of weight, reduces production efficiency, improves design and productive costs.
City rail stainless steel car body light-weight design is extremely important for vehicle loss of weight, because of corrosion-resistant steel mechanical characteristics meeting rapid drawdown when welding is heated, current stainless steel car body welding for steel structure technology extensively adopts spot welding, seam weldering and TIG, MIG welding manner, caused by stainless welding characteristic, the basic structure adopting spot welding overlap joint between plate and plate, body construction requirement of strength and materials'use cost limit, cannot improve body construction intensity from the intensity of car body stainless steel material own and sheet metal thickness, only redesign from welding manner or body construction.It is a vital link that ceiling section redesigns in loss of weight.
Summary of the invention
The invention discloses a kind of city rail stainless steel vihicle ceiling section structure, under the prerequisite ensureing interior space height, the camber beam radian bottom ceiling corrugated plating is reduced, reduce the height between top corrugated plating and floor, the object of vehicle loss of weight can be reached.
The technical solution adopted in the present invention is city rail stainless steel vihicle ceiling section structure, comprise 2 beams and transverse to winding up beam and parallel interval arranges multiple camber beam of winding up, the two ends of camber beam lean respectively on the locating surface winding up beam, the end face at the two ends of camber beam engages with side top board respectively, the middle top surface of camber beam is provided with protection face, protection face comprises corrugated plating region and arc plate region, and corrugated plating region is connected by arc-welding with arc plate region, and air-conditioning platform is arranged in arc plate region; The end face in corrugated plating region and arc plate region end face are at same plane.
Described arc plate region comprises many stringers, and stringer lateral separation is welded on camber beam.
Described camber beam two ends also comprise 2 pieces of stay bearing plates, stay bearing plate is laterally fixed with camber beam.
The radian of described multiple camber beams is identical and section different.
The invention has the beneficial effects as follows: novel corrosion-resistant steel ceiling section structure, effective solution body construction light-weight design difficult point, 20kg can be about by loss of weight in unit length, simplify the technological process of production and enhance productivity, reduce due to material therefor thus reduce material cost.In-built steel structure smallclothes quantity obviously reduces, and smallclothes structure is simply easy to produce and welding, for new type stainless steel. corrosion resistance body construction provides design considerations.

Detailed description of the invention
Below in conjunction with accompanying drawing 1 to accompanying drawing 13, the invention will be further described, city rail stainless steel vihicle ceiling steel structure comprises 2 beams 2 and transverse to winding up beam 2 and parallel interval arranges multiple camber beam 5 of winding up, the two ends of camber beam 5 lean respectively on the locating surface 12 winding up beam 2, the end face at the two ends of camber beam 5 engages with side top board 1 respectively, the middle top surface of camber beam 5 is provided with protection face, protection face forms same plane by corrugated plating region and arc plate region, corrugated plating region is connected by arc-welding with arc plate region, and air-conditioning platform 9 is arranged in arc plate region; The end face in corrugated plating region and arc plate region end face are at same plane.That is reduce at the connection smallclothes consumption in corrugated plating region and arc plate region, directly connect for same plane.As shown in Figure 6, original connection mode is as shown in Figure 3, need to connect as transition with in-built smallclothes 10, the quantity of the part both increased like this, increase car body weight, make troubles also can to production installation, the arc plate region of new design comprises many stringers 8, stringer 8 lateral separation is welded on camber beam 5, plays the effect be fixedly connected with.
