Description

Technical Field

[0001] The utility model relates to the technical field of semi-trailers, and specifically, to a novel main cross beam with a water sprinkler fixing plate and a semi-trailer. Background Art

[0002] During the transportation of existing semi-trailers, the brakes are used frequently, which may cause the temperature of the braking system to be too high, and safety hazards such as brake failure and fire are likely to occur. Therefore, most semi-trailer owners will choose to install a water sprinkler on the semi-trailer. When installing the water sprinkler, it is necessary to assemble and weld the fixing device of the water sprinkler on the main cross beam in the middle of the semi-trailer frame girder. This method requires positioning on the main cross beam first and then welding, which is complex and time-consuming. Moreover, welding will also cause stress concentration, affecting the structural strength of the main cross beam.

[0003] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, and thus provide a novel main cross beam with a water sprinkler fixing plate and a semi-trailer. The utility model not only meets all the functional requirements of existing semi-trailers, but also solves the problem that the assembly and welding of the water sprinkler fixing device on the main cross beam of existing semi-trailers are inconvenient, realizing the diversified needs of semi-trailers.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a novel main cross beam with a water sprinkler fixing plate, including a main cross beam. The main cross beam is a plate structure. Two symmetrically arranged water sprinkler fixing plates are integrally cast and stamped on the main cross beam. The water sprinkler fixing plates are bent on the front side of the main cross beam and are U-shaped plates with openings on the upper side, front side and rear side. Mounting holes for connecting the water sprinkler are punched on the lower side plate of the water sprinkler fixing plate.

[0006] Based on the above, both the upper side edge and the lower side edge of the main cross beam are integrally formed with horizontally bent edges backward.

[0007] Based on the above, the middle part of the lower side edge of the main cross beam has an arc-shaped groove.

[0008] Based on the above, round holes are punched in the middle of the main cross beam, and semi-circular grooves are provided in the middle of both side edges of the main cross beam.

[0009] A semi-trailer includes the novel main cross beam with a water sprinkler fixing plate as described above.

[0010] The utility model has substantial features and progress compared with the prior art. Specifically, the main beam of the utility model is integrally cast and stamped by a mold during production and manufacturing. Two symmetrically arranged sprinkler fixing plates are directly stamped on the main beam. Compared with the existing main beam, the main beam prefabricates the sprinkler fixing plates. In this way, after the semi-trailer leaves the factory, if the semi-trailer owner wants to install a sprinkler, the sprinkler can be directly installed on the sprinkler fixing plate, with simple operation, without the need to assemble and weld the fixing device for installing the sprinkler, saving time and effort. The main beam increases the diversified needs of the semi-trailer and is convenient and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following further describes the technical solutions of the utility model in detail through specific embodiments.

[0017] Embodiment 1

[0018] As Figures 1-3 shown, a new type of main beam with a sprinkler fixing plate includes a main beam 1. The main beam 1 is a plate structure. Two symmetrically arranged sprinkler fixing plates 2 are integrally cast and stamped on the main beam 1. The sprinkler fixing plate 2 is bent on the front side of the main beam 1 and is a U-shaped plate with openings on the upper side, front side and rear side. Installation holes 3 for connecting the sprinkler are punched on the lower side plate of the sprinkler fixing plate 2.

[0019] Flanges 4 that are horizontally bent backward are integrally formed on the upper side edge and the lower side edge of the main beam 1. The flanges 4 can increase the structural strength.

[0020] The middle part of the lower side edge of the main beam 1 has an arc groove 5.

[0021] Round holes 6 are punched in the middle of the main beam 1, and semi-circular grooves 7 are provided in the middle of both side edges of the main beam 1.

[0022] Compared with the existing main crossbeam, a water sprinkler fixing plate 2 is prefabricated on this main crossbeam. After the semi-trailer leaves the factory, when the semi-trailer owner wants to install a water sprinkler, the water sprinkler can be directly installed on the water sprinkler fixing plate 2. The operation is simple and there is no need to assemble and weld the fixing device for installing the water sprinkler again, which saves time and effort. This main crossbeam increases the diversified needs of the semi-trailer and is convenient and practical.

[0023] Embodiment 2

[0024] As Figure 4 shown, this embodiment provides a semi-trailer, which includes the new main crossbeam with a water sprinkler fixing plate as described in Embodiment 1.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
