Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of rail vehicle roof mounting structure, belong to rail vehicle roof structure technical field. BACKGROUND

[0002] The subway car is a dense flow of people, relatively closed space, larger flow of people leads to more serious air pollution in the car. The train air conditioning system can only maintain the comfort of the temperature in the car, and cannot purify the air, and the fresh air of the train air conditioning system is taken from the air in the subway tunnel, the air quality is affected by the particulate matter and emissions generated by subway operation, including dust deposited in the tunnel. The air filter device of the air conditioning system is only set to protect the air conditioning equipment, and cannot filter small particles and dust. To effectively solve the air pollution of the vehicle, it is necessary for each operating unit to improve the maintenance period of air conditioning duct cleaning to maintain the air quality in the car.

[0003] The subway vehicle air conditioning system is mostly arranged on the roof, and the air supply duct is arranged above the interior decorative plate of the vehicle. The air duct needs to form a closed structure. After long-term use of the vehicle, dust and debris will enter the inside of the air duct. In the long-term operation process of the urban rail train, dust will accumulate in the air conditioning duct, affecting the air supply quality of the train and the health of passengers. Each vehicle operator hopes that the roof structure can be quickly disassembled to realize regular cleaning of the vehicle air duct. At present, the solution to regular cleaning of the air duct mainly has two kinds. One is to set a maintenance opening at the bottom of each air duct. This scheme achieves the purpose of cleaning without disassembling the air duct. If the passenger compartment air duct needs to be cleaned, the passenger compartment handrail, air outlet grille, interior top plate and lighting equipment need to be disassembled, and then the air duct needs to be disassembled for cleaning. The handrail, grille and top plate are multiple components that are connected to each other, which requires a large amount of manpower, and frequent disassembly of interior components can easily cause problems such as loosening of connecting parts, thread mismatch, surface paint scratches and component wear. More importantly, it takes a lot of time to complete the above processes, which makes the train unable to operate for a long time, increasing the pressure on the use of the vehicle. Such a process cannot match the existing repair schedule of the vehicle. If this work is carried out during the repair or overhaul period, the repair period is too long, and the purpose of keeping the air duct clean cannot be achieved.

[0004] Another scheme integrates the interior top plate with the air duct, and uses the interior top plate as the bottom of the air duct. A Chinese patent application with application number CN201410820715.1 discloses a kind of rail vehicle air duct plate, middle roof and ventilation grille integrated structure, which integrates the air duct, middle roof and ventilation grille into a whole structure. To clean the air duct, the interior handrail and grille need to be disassembled, and the interior top plate needs to be disassembled for full cleaning of the air duct. This scheme has an advantage over the previous scheme in terms of repair space and disassembly workload, but the air duct has poor air tightness and thermal insulation performance. UTILITY MODEL CONTENT

[0005] In order to overcome the problems in the prior art, the utility model provides a rail vehicle top plate mounting structure, which is beneficial to saving vehicle maintenance cost and shortening the maintenance period, and the specific technical scheme is as follows.

[0007] Characterized in that the top of the rail vehicle further has a middle beam and side beams, the two side beams are located at the two sides of the middle beam, the inner side of the middle top plate is hingedly connected with the middle beam, and the outer side of the air outlet grille is detachably connected with the side beams.

[0008] When the air duct needs to be cleaned, the air outlet grille and the middle top plate can be quickly opened together, so that the air duct is in an exposed state, and the cleaning operation can be performed by opening the maintenance door on the air duct. Since the air outlet grille and the middle top plate are arranged between the middle beam and the side beams, when the air outlet grille and the middle top plate are opened, the handrails (part of the handrails are fixed to the middle beam, and part of the handrails are fixed to the side beams) do not need to be removed, thereby greatly reducing the cleaning difficulty and improving the cleaning efficiency.

[0009] Further, the air outlet grille and the middle top plate are connected through a plurality of first fasteners, the air outlet grille further has a lap plate, the lap plate is lapped below the middle top plate, and sealing material is arranged between the lap plate and the middle top plate. Preferably, the sealing material is sound-absorbing cotton or a rubber sealing strip. The sealing material is beneficial to providing better sealing performance, preventing air conditioner air from leaking from the connection between the air outlet grille and the middle top plate, and reducing vibration and preventing noise; meanwhile, by arranging the lap plate, the connection between the air outlet grille and the middle top plate can be shielded, and the aesthetic degree is improved.

[0010] Further, the air outlet grille is fixed to the side beam through a second fastener, and the air outlet grille further has a shielding plate, which is located below the second fastener. The shielding plate can shield the second fastener, and the aesthetic degree is improved.

[0011] Further, the inner side of the middle top plate is hingedly connected with the middle beam through a hinge.

[0012] Further, the middle beam is connected with a handrail, and the upper end of the handrail is fixedly connected with the middle beam. When the middle top plate is in an open state, the middle top plate does not interfere with the handrail.

[0013] The utility model discloses a rail vehicle roof installation structure, which can realize quick opening of the middle roof inside the rail vehicle, solve the problem of excessive workload and long cycle in the air duct cleaning process. BRIEF DESCRIPTION OF DRAWINGS
