Technical Field

[0001] This utility model relates to the field of train rerailing equipment technology, and in particular to a hollow carbon composite load-bearing beam for train rescue. Background Technology

[0002] The support beam is one of the most critical components of the rerailing equipment. It is used to bear the weight of the derailed train and resist localized concentrated loads. It weighs about 60 kg and has the characteristics of high load capacity and small deformation.

[0003] The current focus of train rerailing equipment is on lightweighting and automation. As the most important support beam in the train rerailing equipment, it forms a stable support through internal profiles to prevent the support beam from tilting or becoming unstable during the rerailing process.

[0004] However, the existing support beams also have significant drawbacks. They are heavy, requiring at least two people to place them during train rerailing operations, which is laborious and affects work efficiency. Furthermore, the exterior of the support beams is directly exposed to the elements, and after prolonged use, they will react with the air, becoming corroded and oxidized, which affects the strength of the support beams. Therefore, hollow carbon composite load-bearing beams for train rescue are proposed to solve the above problems. Utility Model Content

[0009] As a further description of the above technical solution:

[0010] The protective component includes a covering layer disposed on the outside of the top plate and the bottom plate, and the end plate located on the inside of the covering layer. The covering layer is made of carbon fiber material and is formed by winding.

[0011] As a further description of the above technical solution:

[0012] The top plate has multiple through holes in the middle, and all of the through holes are circular.

[0013] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The side panel has two 90° bends at both the top and bottom, and the side panel is located between the covering layer and the profile.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 2-4 An embodiment of this utility model provides a hollow carbon composite load-bearing beam for train rescue, including a top plate 2, which is the main structure of the load-bearing beam and enables the load-bearing beam to be formed. Both ends of the top plate 2 are fixedly connected to end plates 6, and the bottom of the end plates 6 is fixedly connected to a bottom plate 7. The bottom of the top plate 2 is connected to the bottom plate 7 through two end plates 6. At the same time, the two end plates 6 close the ends of the top plate 2 and the bottom plate 7 to form the main frame, which facilitates the installation of subsequent structures. A support component is provided between the top plate 2 and the bottom plate 7, and a protective component is provided on the outside of the top plate 2 and the bottom plate 7.

[0034] The support assembly includes a profile 4, which is fixedly connected between the top plate 2 and the bottom plate 7. The profile 4 provides excellent support between the top plate 2 and the bottom plate 7, forming a support structure. Both ends of the profile 4 are fixedly connected to the inner sides of two end plates 6. Fixing the ends of the profile 4 to the inner sides of the two end plates 6 not only protects the profile 4 but also makes the load-bearing beam more stable, preventing internal structural swaying and thus affecting the overall structural strength. The profile 4 is made of carbon fiber, which has high structural strength and is very lightweight, perfectly compensating for the heavy weight of the load-bearing beam without affecting its structural strength. Two side plates 3 are fixedly connected between the top plate 2 and the bottom plate 7, located on both sides of the profile 4. The side plates 3 on both sides of the profile 4 form a stronger support structure, further enhancing the overall structural strength. The side plates 3 are equipped with [missing information - likely related to structural strength]. Two 90° bends form the side plate 3, which, through bending on both sides, forms a channel steel structure, enhancing its compressive strength. The side plate 3 is located between the cladding layer 5 and the profile 4, and is also protected by the cladding layer 5. The material of the two side plates 3 is carbon fiber. Using carbon fiber reduces weight and increases strength, making the load-bearing beam easier to use. The two end plates 6 are both square, and their cross-sections are the same as those of the top plate 2 and the bottom plate 7. They are fixed together to form a box beam structure. The end plates 6 are located between the profile 4 and the cladding layer 5. The end plates 6 are supported by the profile 4 to increase the support strength. At the same time, the external cladding layer 5 reduces external corrosion and damage, extending service life. A cavity is set in the middle of the profile 4. Designing the profile 4 as a hollow structure further reduces its weight. By setting up support components, carbon fiber material supports multiple support structures, significantly reducing the weight of the load-bearing beam while maintaining strength, making it easier to use and improving efficiency during rescue operations.

[0035] Reference Figure 2 and Figure 4 The protective component includes a covering layer 5, which is located on the outside of the top plate 2 and the bottom plate 7, and the end plates 6 are located on the inside of the covering layer 5. The covering layer 5 surrounds the top plate 2, the bottom plate 7 and the two end plates 6, preventing them from contacting the outside world and enhancing the service life of the load-bearing beam. The covering layer 5 is made of carbon fiber material and is formed by winding. The covering layer 5 is formed by winding carbon fiber material along the top plate 2 and the bottom plate 7, surrounding the internal structure and forming a protective structure to prevent the internal steel from being contaminated and corroded by the outside, thus extending its service life.

[0036] Reference Figure 3 The top plate 2 has multiple through holes 1 in the middle, and all through holes 1 are circular. By setting the circular through holes 1 in the middle of the top plate 2, it is convenient to use other tools to cooperate with the through holes 1 for support, and at the same time to rescue the train.

[0037] Working principle: First, the top plate 2 and the bottom plate 7 serve as the main frame of the load-bearing beam. The main frame is formed by fixing the upper end plate 6 to both ends of the top plate 2 and the bottom plate 7. The weight of the load-bearing beam is reduced by a small amount of structural material. Then, the profile 4 is fixed between the top plate 2 and the bottom plate 7 as the main support. Two side plates 3 are fixed on both sides of the profile 4. The profile 4 and the side plates 3 serve as the main support components, which provide compressive strength to the load-bearing beam while reducing its weight. When in use, it can be moved by a single person, improving work efficiency.

[0038] Secondly, a covering layer 5 is provided on the outside of the top plate 2, bottom plate 7 and two side plates 3 to cover the internal structure. When in use, the covering layer 5 is in direct contact with the outside, which can effectively protect the internal components, improve the service life of the load-bearing beam, and save costs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
