Description

Technical Field

[0001] This utility model relates to railway tank cars, specifically to a railway tank car with a top protective device. Background Technology

[0002] Railway tank cars are mostly used to transport liquid or gaseous media such as light oil, chemicals, and liquefied gas. These media are generally flammable, explosive, and toxic, requiring high safety standards during transportation. In particular, in the event of derailment or overturning, leakage of media should be avoided to prevent secondary hazards.

[0003] Currently, manholes, valves, and other components on the top of railway tank cars typically lack protective devices. If these components are damaged after a derailment or overturning, media leakage may occur, potentially leading to serious consequences such as combustion or explosion. To ensure the safety of railway tank car transportation and further improve the leakage prevention performance of tank cars in the event of derailment or overturning, the development of a protective device for the top of railway tank cars is imperative. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problem that existing railway tank cars often lack protective devices for components such as manholes and valves on the top, which may be damaged after the tank car derails and overturns, leading to leakage of the medium and potentially causing serious consequences such as combustion and explosion. The present invention provides a railway tank car with a top protective device.

[0005] To achieve the above objectives, the technical solution proposed by this utility model is as follows:

[0006] A railway tank car with a top protective device includes a tank body and a manhole and safety valve assembly located on top of the tank body; its special feature is that:

[0007] It also includes two sets of protective components that are fixed to the top of the tank along the extension direction of the tank body and are correspondingly set on the front and rear sides of the manhole and safety valve assembly on the top of the tank.

[0008] Each set of protective components includes a fixed pad, multiple sets of support frames and a cover plate. The fixed pad is fixedly installed on the top of the tank and extends in an axial direction perpendicular to the tank. The multiple sets of support frames are evenly fixed on the fixed pad along the extension direction of the fixed pad.

[0009] Each set of support frames includes a first support plate, a second support plate, and a third support plate connected in sequence. The first support plate, the second support plate, and the third support plate form a trapezoidal cavity structure. The large end of the trapezoidal cavity structure is connected to the fixed pad. The second support plate is located on the side near the manhole on the top of the tank. The two second support plates located at both ends of the fixed pad are also provided with reinforcing ribs connected to the fixed pad on the lower side.

[0010] The cover plate includes an upper cover plate and a side cover plate that are connected to each other. The upper cover plate is used to connect the small end of the trapezoidal cavity structure of each set of support frames, and the side cover plate is used to connect the side end of the trapezoidal cavity structure of each set of support frames.

[0011] Furthermore, the front and rear sides of the fixing pad are both arc-shaped and curved inward, with the two ends near the manhole on the top of the tank extending towards the manhole on the top of the tank to form an extension section for installing the reinforcing rib plate, which is fixedly connected to the second support plate and the fixing pad.

[0012] Furthermore, the support frame consists of 3 sets.

[0013] Furthermore, the height of the protective assembly is higher than the height of the manhole on the tank top and the safety valve.

[0014] Furthermore, the width of the protective component is greater than the diameter of the manhole on the tank top, and also greater than the width of the safety valve assembly.

[0015] Furthermore, the fixing pad, multiple sets of support frames, and cover plate are all made of steel plates.

[0016] Furthermore, the fixed pad, multiple sets of support frames, and cover plate are all fixedly connected by welding.

[0017] Furthermore, the two sets of protective components are respectively installed below the tank top guardrails on opposite sides of the tank top, and their upper covers are fixedly connected to the tank top guardrails.

[0018] The beneficial effects of this utility model are:

[0019] [1] The structure of the railway tank car with a top protection device is simple and the stability is strong. By setting protective components on both sides of the manhole and safety valve group on the top of the tank, the manhole and safety valve group on the top of the tank can be effectively protected in three directions: horizontal, lateral and vertical. This prevents external uncontrollable factors from damaging the manhole and safety valve group in the case of derailment and overturning, which would lead to media leakage. This effectively improves the safety performance of the railway tank car and ensures the integrity of the tank body.

[0020] [2] The support frame of this utility model forms a trapezoidal cavity structure, which is covered by an upper cover plate and a side cover plate. The side cover plate is at a certain angle to the top of the tank, which can effectively reduce the wind resistance of the protective components and ensure the stability of the protective components.

[0021] [3] The height and width of the protective component of this utility model are both greater than the height and width of the manhole on the tank top and the safety valve group. The manhole on the tank top and the safety valve group are completely placed in the protective cavity formed by the two symmetrically arranged protective components, which can effectively ensure the protection of the manhole on the tank top and the safety valve group, and improve the reliability and practicality of the device.

[0026] like Figure 1 As shown, a railway tank car with a top protective device includes a tank body and a top manhole 1 and a safety valve group 2 disposed on the top of the tank body. It also includes two sets of protective components 3 fixed to the top of the tank body along the extension direction of the tank body and correspondingly disposed on the front and rear sides of the top manhole 1 and the safety valve group 2. The height of each set of protective components 3 is higher than the height of the top manhole 1 and the safety valve group 2, and the width of the protective component 3 is greater than the diameter of the top manhole 1 and also greater than the width of the safety valve group 2. The top manhole 1 and the safety valve group 2 are completely placed in the protective cavity formed by the two symmetrically arranged protective components 3, which can effectively ensure the protection of the top manhole 1 and the safety valve group 2.

[0027] like Figure 2 As shown, the protective assembly 3 includes a fixed pad 4, three sets of support frames 5, and a cover plate 6. The fixed pad 4 is fixedly installed on the top of the tank and extends in a direction perpendicular to the axial direction of the tank. The front and rear sides of the fixed pad 4 are arc-shaped and both bend inward. The two ends near the manhole 1 on the top of the tank extend towards the manhole 1 on the top of the tank to form an extension section for installing the reinforcing rib plate 10. The reinforcing rib plate 10 is fixedly connected to the second support plate 8 and the fixed pad 4. The three sets of support frames 5 are fixed on the fixed pad 4 along the extension direction of the fixed pad 4. Each set of support frames 5 includes a first support plate 7, a second support plate 8, and a third support plate 9 connected in sequence. The first support plate 7, the second support plate 8, and the third support plate 9 form a trapezoidal cavity structure. The large end of the trapezoidal cavity structure is connected to the fixed pad 4. The second support plate 8 is located on the side near the manhole 1 on the top of the tank. The two second support plates 8 located at both ends of the fixed pad 4 are also provided with reinforcing rib plates 10 connected to the fixed pad 4 on the lower side to keep the device stable.

[0028] The cover plate 6 includes an upper cover plate 11 and a side cover plate 12 that are connected to each other. The upper cover plate 11 is used to connect the small end of the trapezoidal cavity structure of each set of support frames 5, and the side cover plate 12 is used to connect the side end of the trapezoidal cavity structure of each set of support frames 5. The side cover plate 12 has a certain angle with the top of the tank, which can effectively reduce the wind resistance of the protective component 3 and ensure the stability of the protective component 3.

[0029] The fixing pad 4, the multiple sets of support frames 5 and the cover plate 6 are all steel plates, and the fixing pad 4, the multiple sets of support frames 5 and the cover plate 6 are all fixedly connected by welding.

[0030] The two sets of protective components 3 can also be respectively installed on the opposite sides of the tank top guardrail. The upper cover plate 11 is fixedly connected to the tank top guardrail, which not only improves the structural stability of the tank top guardrail, but also saves the operating space on the top of the tank, effectively improving the overall stability and reliability of the structure.
