Problems solved by technology
[0002] The roof of a railway freight car is generally a welded structure of plate shell and curved beam. Due to the limitation of the width of the steel plate, the plate shell of the roof is now welded by multiple plates arranged horizontally. There are many, so the welding workload is large, and the quality of the welds is not easy to guarantee. The roof of the car transporter in the truck is this structure, because the roof plate shell is a horizontal combination structure of thin steel plates, and the car body is longer and has many seams. , so the manufacturing process is complicated and the production efficiency is low
Therefore, whether the roof of this structure is a riveted structure or a welded structure, quality problems are prone to occur at the seams.

Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the examples.
[0024] Such as Figure 1~2 As shown, the present invention proposes an integral vertical roof for railway wagons, which includes a plate-shaped first side panel 1 and a second side panel 2, and the first side panel 1 and the second side panel 2 both include a horizontal plate, the second angled facade 16 connected obliquely to the first end of the horizontal plate, and the first angled facade 15 vertically connected to the second angled facade 16, the first side panel 1 and the second side panel 2 The second end of the middle horizontal plate is bent into a hook-shaped structure 3, and the two hook-shaped structures 3 form a hook-shaped nest, so that the overall longitudinal roof is leak-proof, and the first side panel 1 is close to the back. The hook structure 3 is provided with a semicircular protrusion 4 for positioning.
[0025] In the above-mentioned embodiment, the protru...

The invention relates to an integral longitudinal paved roof for a rail wagon and a production method thereof. The integral longitudinal paved roof for the rail wagon includes a first side panel and asecond panel which are in a plate shape, the first side panel and the second side panel both include horizontal plates, second included angle vertical faces which are aslant connected with the horizontal plates and first included angle vertical faces which are vertically connected with the second included angle vertical faces, and second ends of the horizontal plates of the first side panel and the second side panel are bent to form swivel-clasp-shaped structures; and the two swivel-clasp-shaped structures form a swivel-clasp-shaped imbedded sleeve, and the position, next to the swivel-clasp-shaped structures, of the first side panel is provided with a semicircle protrusion for location. According to the integral longitudinal paved roof for the rail wagon and the production method thereof, the second end of the first side panel and the second end of the second panel are connected as a whole through the swivel-clasp-shaped structures in a mutual embedded sleeving mode, the process problems of welding deformation and the like caused by welding seams can be eliminated, the production line manufacturing is facilitated, leakage accidents can be completely eradicated, and the manufacturing quality can be ensured.
Description
technical field [0001] The invention relates to a roof shell of a railway freight car, in particular to an integral vertically laid roof for a railway freight car and a manufacturing method thereof.

Due to the limitation of the width of the steel plate, the plate shell of the roof is now welded by multiple plates arranged horizontally. There are many, so the welding workload is large, and the quality of the welds is not easy to guarantee. The roof of the car transporter in the truck is this structure, because the roof plate shell is a horizontal combination structure of thin steel plates, and the car body is longer and has many seams. , so the manufacturing process is complicated and the production efficiency is low. Therefore no matter whether the roof of this structure is a riveted structure or a welded structure, quality problems are prone to oc...
