Description

Rail vehicle roof flaps

technical field

The utility model relates to a composition and installation structure of a roof movable cover of a rail vehicle, which is used for hoisting in, hoisting out and installation of large equipment from the outside of the roof to the inside of the car body, and belongs to the field of mechanical processing and transportation.

Background technique

The existing rail transportation vehicles commonly used at home and abroad, such as EMUs, subways, urban light rails, etc., in order to meet the installation requirements of large-scale equipment and module structures in the car, and improve production efficiency. It is usually necessary to reserve an opening of sufficient size in the roof. After the hoisting of the equipment in the car is completed, the roof opening is sealed.

The limitation of this type of car body structure and sealing method is that the installation structure is complicated, which leads to low work efficiency, and the sealing effect is poor.

Utility model content

The rail vehicle roof flap described in the utility model is to solve the problems and defects of the above-mentioned prior art and innovatively propose a hoisting flap structure specially set on the roof, which can be directly installed when the equipment in the car is hoisted. Just open the roof flap. After the equipment is hoisted, a good connection and seal is formed between the movable cover and the roof, which does not affect the overall rigidity and sealing requirements of the roof.

The design purpose of the utility model is to reserve a hoisting passage through the roof flap, and simultaneously take into account the design requirements of light weight, sealing performance and rigidity of the vehicle body.

In order to achieve the above-mentioned design purpose, the described rail vehicle roof flap mainly includes:

flap body and inspection door,

The flap body is bolted to the mount on the roof,

The inspection door is fixedly installed on the outside of the main body of the flap through a hinge and an inspection door lock.

As in the above-mentioned basic scheme features, the main body of the flap is installed on the roof to form a reserved hoisting space for the equipment in the car. When the equipment needs to be hoisted, the main body of the flap can be directly removed, which saves time and effort and does not damage the roof. The original connection and sealing structure.

When performing online maintenance on the equipment in the vehicle, it is only necessary to open the inspection door.

In order to further improve the connection stability and sealing performance between the main body of the flap and the roof, the improvement plan that can be adopted is:

The main body of the flap is welded by a skeleton, an outer skin and an inner skin, and an aluminum honeycomb panel is filled between the outer skin and the inner skin.

The main body of the above-mentioned movable cover forms a lightweight structure. The aluminum honeycomb panel can be bonded with the inner skin and the outer skin with an adhesive, and the inner skin, the outer skin and the skeleton can also be sealed by coating. Glue to seal.

The improvement for the overall sealing structure of the roof is that a sealing material and a sealing rubber strip are lined between the flap main body and the roof to isolate the noise of the external environment and prevent rainwater or other impurities from entering the car.

The improvement for the sealing structure of the main body of the flap is that a sealing material is lined between the main body of the flap and the inspection door to prevent rainwater or other impurities from entering the vehicle through the inspection door.

In order to improve the temperature-proof performance of the roof position, at least one layer of heat-insulating material is adhered to the inner side of the main body of the flap.

In addition, at least one layer of thermal insulation material may also be adhered to the inner side of the inspection door.

For convenience the flap main body is unloaded from the roof, a handle can be provided on the flap main body.

The flap body, the inspection door and the roof have the same outer contour shape.

In summary, the advantages and beneficial effects of the utility model rail vehicle roof flap are:

1. Realize a hoisting movable cover structure specially reserved for the roof. The original sealing and connection structure of the roof will not be damaged during the hoisting operation, which eliminates the complicated workload of repeated welding of the roof and reduces the labor load of operators.

2. A good sealing connection is formed between the movable cover and the roof, which is conducive to the overall rigidity and sealing requirements of the roof.

3. It is beneficial to improve the lightweight design of the car body and greatly reduce the weight of the roof.
