Problems solved by technology

[0004] In order to overcome the disadvantage that the existing subway vehicles have no space to design the roof side beams, that is, the design space is limited, so the roof structure with side beams cannot be installed with a relatively high plug door, the present invention aims to provide a subway without side beams Vehicle roof structure, which can ensure the installation of a high-height electric sliding door, and at the same time strengthen the roof to meet the strength requirements of the roof itself and the connection strength with the side wall

Embodiment Construction

[0034] A roof structure for subway vehicles without side beams, such as figure 1 As shown, the roof frame is composed of side roof 1, middle roof 7, air-conditioning connecting curved beam 2, roof curved beam 3, and air-conditioning beam assembly 4 spot welding connections, and the air-conditioning installation platform 5 is respectively placed in the gaps at both ends of the roof frame , the two sides of the corrugated roof 6 are lapped on the middle roof 7 and the side roof 1 respectively, and spot welding with the roof frame is completed. Wherein the side top plate 1 is provided with a row of connection holes for plug welding connection with the side wall parts to enhance the connection strength and rigidity between the large parts, and the middle top plate 7 is set to compensate for the loss of stiffness caused by canceling the roof side beams. The sealing performance of the roof and the reduction of arc welding deformation, the corrugated roof 6 and the middle roof 7 are ...

Abstract

The invention discloses a metro car roof structure without a boundary beam. In order to solve the problems that the traditional car roof structure with a boundary beam can not be equipped with a higher sliding plug door, the metro car roof structure without the boundary beam comprises a car roof bending beam, two side top plates arranged at the two ends of the car roof bending beam, and air-conditioning installation platforms fixedly arranged at the two ends of the side top plates through air-conditioning connecting bending beams; connecting holes which are directly and fixedly arranged in the upper parts of car side walls are formed in the side top plates, and a middle top plate fixedly arranged on the car roof bending beam is arranged between the two air-conditioning installation platform; and a corrugated top plate fixedly arranged on the car top bending beam and the air-conditioning connecting bending beams is arranged between the middle top plate and the side top plate. The car roof provided by the invention has the advantages of simple structure, lighter weight, good strength, no water accumulation, and convenience in lifting.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicle body structure, in particular to a roof structure of a subway vehicle without side beams. Background technique [0002] At present, the roof of the stainless steel rail vehicle body is usually provided with a full-length rolled steel as a side beam, and the side beam is usually directly spot-welded with the roof curved beam on the inner side, or between the roof curved beam and the roof side beam There are connecting angle irons to connect the curved beams to each other as a whole; the outer side is spot welded with the side roof to form a semi-closed structure with greater rigidity. The side beam is one of the main structures for the vehicle body to transmit longitudinal force and vertical force, which can improve the overall rigidity of the roof and facilitate lifting and installation. Due to the abundant design space of existing vehicles, there is no motivation to design a subway ...
