Abstract
The utility model discloses a roof structure of a rail car and provides a novel roof structure. The roof is formed by welding air conditioner flat roofs and a flat roof framework, and the flat roof framework is formed by welding a cap-shaped beam and a flat roof plate. With the car roof structure and the processing method provided by the utility model, the welding work capacity and the welding deformation amount of the car roof structure are reduced, and the flatness of the car roof surface is improved. The car roof structure comprises two air conditioner flat roofs for mounting a vehicle-mounted air conditioner and a flat roof framework formed by welding the beam and the flat roof plate; drain pipes for draining water are arranged on the two longitudinal sides of the flat roof framework; and the air conditioner flat roofs each are provided with an inward-concave basin-shaped structure with respect to the flat roof framework. The flat roof framework effectively realizes the lightening design while satisfying the rigidity and the mechanical intensity, and is easy to improve the flatness of the car roof surface. The basin-shaped structure formed by the air conditioner flat roofs is easy to carry out water test experiment so that the defect in the welding can be found in advance, thus rectifying and reforming can be carried out purposefully.
Description
Technical field
The utility model is to the improvement of guideway vehicle vehicle top air conditioner installation with discharge structure, takes a kind of modular flat-tope structure specifically, belongs to mechanical manufacturing field.
Background technology
The present guideway vehicle of place in operation, interior environment system is installed on roof at large and rainwater is set, snow-broth compiles discharging mechanism, may be summarized to be the structural pattern of roof carrying platform+ceiling+drain hose.
When roof installs an air-conditioner device; Its carrying platform generally adopts plate-girder formula structure; Promptly overlap out earlier the roof skeleton to carry the weight of roof equipment such as air-conditioning; Auxilliaryly above skeleton again establish the platform components such as ceiling of monoblock, cause roof heavier and be unfavorable for optimizing light-weighted car body design and improve moving velocity.
In addition because vehicle adopts the steel car body structure, flat-top welding job amount is big and be prone to cause producing bigger distortion when installing an air-conditioner, and welding quality is difficult to control.
After the assembly welding completion, the planeness on roof surface can be overproof significantly, therefore needs the follow-up flame that carries out to regulate, and not only wastes time and energy, and also can directly reduce the intensity of roof mother metal.
Air-conditioning flat top surface planeness is relatively poor, also can form the water at air-conditioning flat-top place and influences the vehicle operation life-span.
Because in the prior art, the air-conditioning flat-top can't carry out water earlier and detect, and the sealing property of the steel structure of car body behind the assembly welding can only rely on subsequent handling to detect, in case water occurs and leakage problems promptly is difficult to handle appropriate.
In view of this special present patent application that proposes.
The utility model content
The described guideway vehicle roof structure of the utility model; Its design goal is to solve the problem of prior art existence and provides a kind of later-model roof structure; Roof is welded by air-conditioning flat-top and flat-top skeleton, and the flat-top skeleton is welded by the beam and the ceiling of hat.Roof structure and job operation through the utility model proposes to reach the roof structure that reduces welding job amount, deflection, improve the planeness on roof surface.
Another design goal is to realize reducing the flash welding amount to the air-conditioning flat-top, through trying the water behind bathtub construction and the assembly welding to control the water-stop quality effectively.
Design goal also is, improves the light-weight design level of roof global facility.
For realizing above-mentioned design goal, described guideway vehicle roof structure mainly includes:
Be used to install 2 air-conditioning flat-tops of on-board air conditioner, and the flat-top skeleton that is welded by beam and ceiling;
Be provided with the drain hose that is used for draining in the vertical both sides of flat-top skeleton;
The air-conditioning flat-top has the bathtub construction of indent with respect to the flat-top skeleton.
Like above-mentioned basic scheme characteristic, above-mentioned flat-top skeleton has been realized light-weight design effectively under the prerequisite that satisfies rigidity and mechanical strength, and is easy to improve the planeness on roof surface.
The bathtub construction that the air-conditioning flat-top forms is easy to try the water experiment and the defective that can find to weld existence in advance, thereby rectifies and improves targetedly.
For improving surface evenness and welding quality further, the improvement project that can take is, described beam has the cross-section structure of hat, and the planar section of beam carries out spot welding mutually with ceiling and is connected, and the hat flanging of adjacent two beams carries out spot welding each other and connects.
The flat-top skeleton adopts hat Liangping face and the mutual spot welding mode of ceiling, can guarantee the surface evenness of ceiling point postwelding effectively, can't be because of the both sides of the hat beam welding processing quality that has influence on not in the same plane.
Further improve and refinement roof whole rigidity, described drain hose has wing flanging, and the wing flanging of drain hose carries out spot welding with ceiling and is connected.
Drain hose both can weld with ceiling, also can be used as post and beam construction simultaneously and carried out reinforcement for the integral rigidity of roof.
Be that to connection of air-conditioning flat-top and hermetically-sealed construction improvement described air-conditioning flat-top, its installation frame inner ring adopt the welding connection of flanging bight, its outer ring adopts angle bar spot welding to beat the glue connection mode.
Adopt the welding of flanging bight at air-conditioning flat-top sealing frame inner ring, can directly reduce welding deformation amount, also play the leak free effect simultaneously.
Adopt angle bar spot welding to beat the glue mode in its outer ring, can cancel original full weld mode with reduction welding job amount, but still can reach identical sealing, waterproof effect.
Content to sum up, advantage and beneficial effect that the utility model guideway vehicle roof structure has are:
1, realizes a kind of new car roof construction and job operation, can reduce welding job amount and deflection effectively, improve the planeness on roof surface.
2, air-conditioning flat-top flash welding work amount is able to reduce, behind the assembly welding through trying the water to control the water-stop crudy effectively.
3, help improving the light-weight design level of roof global facility.
