Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 and 2, the roof of the truck of the present embodiment includes a roof panel 10, a plurality of sills 20, and a side rail 30. The plurality of curved beams 20 are connected with the roof panel 10, and the plurality of curved beams 20 are arranged at intervals along the length direction of the roof panel 10; the side member 30 is connected to the roof panel 10, and the side member 30 extends in the longitudinal direction of the roof panel 10.

By applying the technical scheme of the utility model, the longitudinal beam 30 is additionally arranged on the roof panel 10, and the extending direction of the longitudinal beam 30 is the same as the length direction of the roof panel 10. The side rail 30 can improve the overall rigidity and strength of the roof in the longitudinal direction of the roof, thereby reducing the probability of collapse of the middle of the roof and improving the corrosion resistance of the roof.

As shown in fig. 1 and 2, in the present embodiment, the side members 30 are a plurality of members arranged at intervals in the width direction of the roof panel 10. The structure can further improve the rigidity and the strength of the roof in the length direction, so that the probability of collapse of the middle part of the roof is further reduced, and the corrosion resistance of the roof is improved.

As shown in fig. 1, 2, and 4, in the present embodiment, the plurality of side members 30 are uniformly arranged in the width direction of the roof panel 10, and the distance between two adjacent side members 30 is 300mm to 1500 mm. In the structure, the plurality of longitudinal beams 30 uniformly improve the rigidity and the strength of the roof, and the phenomenon that the local rigidity and the strength of the roof are weak is prevented. In addition, if the distance between two adjacent side rails 30 is too far, the effect of improving the rigidity and strength of the roof is limited. If the distance between two adjacent stringers 30 is too close, this results in a waste of production material for the stringers 30. The above structure enables the side rails 30 to be provided as little as possible while ensuring the rigidity and strength of the roof, thereby achieving the effect of saving the production cost.

As shown in fig. 1, 2 and 4, in the present embodiment, the curved beam 20 and the longitudinal beam 30 are located on the same side of the roof panel 10, the longitudinal beam 30 includes a plurality of longitudinal beam sections 31 arranged at intervals in the longitudinal direction of the roof panel 10, the longitudinal beam sections 31 and the curved beams 20 are alternately arranged in the longitudinal direction of the roof panel 10, and both ends of the longitudinal beam sections 31 are connected to two adjacent curved beams 20. In the above structure, the camber beam 20 and the longitudinal beam 30 are arranged on the same side, so that the rigidity and the strength of the whole roof can be improved better. In addition, the connection between the camber beam 20 and the longitudinal beam 30 can further improve the connection stability between the camber beam 20 and the longitudinal beam 30, thereby further improving the rigidity and strength of the whole roof. When the rocker 20 and the side member 30 are provided on the inner surface of the roof panel 10, a lining panel is further provided on the roof. The above-described structure, in which the side member segments 31 and the side members 20 are alternately arranged in the longitudinal direction of the roof panel 10, enables the lower surfaces of the side members 30 and the side members 20 to be located on the same arc-shaped surface, thereby facilitating the connection of the inner panel to the roof.

As shown in fig. 2, 3 and 6, in the present embodiment, the curved beam 20 is a hat-shaped steel, the longitudinal beam section 31 is a channel steel, the curved beam 20 includes a boss 21 and wing plates 22 located at both sides of the boss 21 in the longitudinal direction of the roof panel 10, the wing plates 22 are connected to the roof panel 10, the end surface of the longitudinal beam 30 close to the notch is connected to the roof panel 10, and the end surface of the longitudinal beam section 31 close to the curved beam 20 is provided with a first notch 311 avoiding the wing plate 22 of the curved beam 20. In the structure, the roof panel 10 is of an arc-shaped structure, and the longitudinal beam 30 is arranged to be the channel steel to ensure that the longitudinal beam 30 is abutted to the roof panel 10 effectively due to the narrow upper end face of the channel steel, so that the longitudinal beam 30 is connected with the roof panel 10 conveniently. In addition, since the curved beam 20 has the wing plate 22, when the end portion of the side member segment 31 abuts against the boss 21 of the curved beam 20, the side member segment 31 is directly pressed against the wing plate 22 of the curved beam 20, so that a gap is formed between the side member segment 31 and the roof panel 10, and therefore, when the side member segment 31 is welded to the roof panel 10, the side member segment 31 needs to be pushed to abut against the roof panel 10, which causes inconvenience in welding. The first notch 311 avoiding the wing plate 22 of the curved beam 20 is formed in the longitudinal beam section 31, so that the longitudinal beam section 31 can be directly abutted against the roof panel 10, and the longitudinal beam section 31 can be conveniently welded on the roof panel 10. It should be noted that, when the longitudinal beam section 31 and the roof panel 10 are welded, the longitudinal beam section 31 and the roof panel 10 may be welded in a section welding manner, which can reduce the length of the welding seam between the longitudinal beam section 31 and the roof panel 10, thereby reducing the deformation degree of the roof panel 10 after welding, and ensuring the flatness of the roof panel 10.

Of course, in other embodiments not shown in the figures, the camber beam and the longitudinal beam may both be provided as channel steel, or both the camber beam and the longitudinal beam may be provided as hat steel, or the camber beam may be provided as channel steel and the longitudinal beam may be provided as hat steel.

It should be noted that, the roof panel 10 and the camber beam 20 are made of metal plates with a thickness of 2mm to 3mm, and if the thickness of the metal plates is too large, the weight of the whole roof is increased, and further the self weight of the whole truck is increased, which results in the reduction of the loading capacity of the truck. If the thickness of the metal plate is too small, the rigidity of the roof is low and the roof is easily damaged. Therefore, the thickness of the metal plate is set to be between 2mm and 3mm, so that the weight of the side wall can be reduced as much as possible under the condition that the strength of the pressing plate assembly is ensured.

Because the roof panel 10 and the camber beam 20 have small thicknesses, when the camber beam 20 is welded to the roof panel 10, if the edge of the camber beam 20 is welded to the roof panel 10 as a whole, the welded roof panel 10 and the camber beam 20 may be deformed seriously or even generate weld leakage. In order to solve the above problem, as shown in fig. 2 and 6, in the present embodiment, the curved beam 20 is made of hat-shaped steel, the curved beam 20 is provided with a plurality of welding holes 221, the curved beam 20 includes a boss 21 and wing plates 22 located on both sides of the boss 21 in the longitudinal direction of the roof panel 10, the plurality of welding holes 221 are spaced on the wing plates 22 in the longitudinal direction of the curved beam 20, and the distance between adjacent welding holes 221 is between 150mm and 250 mm. In the structure, the welding area of the roof panel 10 and the camber beam 20 is small, the deformation amount of the roof panel 10 and the camber beam 20 can be reduced to the greatest extent, the flatness of the roof panel 10 is favorably improved, and the probability of welding leakage can be reduced. Preferably, the distance between adjacent solder holes 221 is 200 mm.

As shown in fig. 1 to 4, in the present embodiment, the curved beam 20 and the side member 30 are provided on the inner side surface of the roof panel 10. If the camber beam 20 and the longitudinal beam 30 are disposed on the outer side surface of the roof panel 10, the air resistance to which the truck is subjected during operation may increase, and the maximum operation speed of the truck may be reduced. The structure arranges the camber beam 20 and the longitudinal beam 30 on the inner side surface of the roof panel 10, which can significantly reduce the air resistance of the truck in the operation process, thereby increasing the maximum operation speed of the truck.

The traditional roof plate 10 is formed by welding a plurality of metal plates, the assembly difficulty is high, and the flatness of the welded roof plate 10 is difficult to guarantee. Poor flatness of the roof panel 10 results in a depressed location in the roof that is prone to water and corrosion. To solve the above problem, as shown in fig. 1, in the present embodiment, the roof panel 10 is made of a single plate. The structure can improve the flatness of the roof panel 10, thereby improving the corrosion resistance of the roof panel 10 and prolonging the service life of the roof panel 10.

As shown in fig. 1, 2 and 5, in the present embodiment, the roof further includes side rails 40, the two long sides of the roof panel 10 are each provided with the side rail 40, the two side rails 40 are symmetrical along the longitudinal plane of the roof panel 10, the side rails 40 are bent plates, and the side rails 40 include first connecting plates 41 connected to the long sides and second connecting plates 42 connected to the ends of the bent beams 20. In the above structure, the side members 40 are provided to facilitate connection between the roof of the truck and the side walls of the body of the carriage. Specifically, when the roof and the side wall are connected, the roof and the side wall can be welded by the second connecting plate 42, so that the roof can be conveniently connected to the side wall. The need of welding each camber beam 20 on the side wall is avoided, and the installation efficiency of the truck is improved.

As shown in fig. 1, 2 and 5, in the present embodiment, the curved beam 20 is provided on the inner surface of the roof panel 10, the first connecting plate 41 is connected to the inner surface of the roof panel 10, and the curved beam 20 is provided with the second notch 23 that avoids the first connecting plate 41. In the above structure, the first connecting plate 41 is connected to the inner surface of the roof panel 10, and the second notch 23 avoiding the first connecting plate 41 is provided on the curved beam 20, so that the curved beam 20 can abut against the roof panel 10 and the first connecting plate 41 at the same time, thereby preventing the curved beam 20 from directly abutting against the first connecting plate 41 and generating a gap with the roof panel 10, and facilitating the welding of the curved beam 20 on the roof panel 10.

As shown in fig. 7, the present application further provides a car, an embodiment of a car according to the present application includes a car body 50 and a roof 70. The roof 70 is provided on the cabin body 50, and the roof 70 is the roof described above. In the structure, the car roof has the advantages that the middle part is not easy to collapse and the corrosion resistance is high, so that the car with the car roof also has the advantages.

The present application further provides a truck (not shown), an embodiment of the truck according to the present application comprises a plurality of wagons 60, the plurality of wagons 60 being connected end to end, the wagons 60 being as described above. In the above configuration, since the vehicle compartment 60 has an advantage that the roof is not easily collapsed, the truck having the same also has the above advantage.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
