Description

Technical Field

[0001] This application relates to the field of rail transit technology, and in particular to an equipment hoisting system and a rail vehicle. Background Technology

[0002] The installation of braking equipment is a crucial step in the installation of undercarriage equipment on rail vehicles. Traditional installation methods typically require installing each braking device individually onto the vehicle chassis, then hoisting and installing other miscellaneous equipment one by one, and finally connecting the pipelines to the equipment one by one.

[0003] In existing technologies, the installation process for braking equipment and other undercarriage components is cumbersome and inefficient. Because each braking device must be installed individually, followed by the individual hoisting of other scattered equipment, and finally the connection of pipelines, the entire installation process involves multiple steps that cannot be performed simultaneously. The scattered and complex installation of each component leads to low construction efficiency, increasing construction time and costs. Furthermore, this decentralized installation method results in low space utilization, increased vehicle weight, and negatively impacts the overall performance and economy of the rail vehicle. Summary of the Invention

[0004] The purpose of this application is to provide an equipment hoisting system that integrates braking equipment into independent single-position and double-position brake boxes, and connects the air circuits through longitudinal pipe rows. This achieves pre-assembly under the vehicle and integrated installation on board, effectively improving construction efficiency, reducing installation procedures, and increasing space utilization, thus solving the problems of cumbersome and inefficient installation in traditional methods. Another purpose of this application is to provide a rail vehicle.

[0005] To achieve the above objectives, this application provides an equipment hoisting system, comprising:

[0006] Both the first-position brake box and the second-position brake box are integrated with braking devices. The first-position brake box and the second-position brake box are installed as independent integrated modules at both ends of the rail vehicle.

[0007] The longitudinal pipe array is connected at both ends to the first-position brake box and the second-position brake box respectively, so as to realize the air circuit connection between the first-position brake box and the second-position brake box.

[0008] In some embodiments, the longitudinal tube bank includes:

[0009] The main body of the pipe bank is located between the first-position brake box and the second-position brake box;

[0010] Multiple hoses are distributed at both ends of the main body of the pipe bank. Each hose is connected to an air port of the main body of the pipe bank. Each hose is also connected to the first-position brake box or the second-position brake box.

[0011] In some embodiments, the pipe bank body includes:

[0012] A longitudinal pipeline extends longitudinally between the first-position brake box and the second-position brake box, and a plurality of the longitudinal pipelines are distributed laterally perpendicular to the extension direction of the pipeline.

[0013] A connecting bar extends laterally in the direction in which the longitudinal pipelines are distributed, the connecting bar is connected to the longitudinal pipelines, and the connecting bar is installed on the rail vehicle.

[0014] In some embodiments, at least one of the first-position brake box and the second-position brake box is provided with a support structure, which is mounted on the side beam of the rail vehicle.

[0015] In some embodiments, the support structure includes a lug and a liner, the side beam has a process hole for the lug to move from the lower side of the side beam to the upper side of the side beam, the liner is located between the upper side of the side beam and the lug, the lug is connected to the liner, and the liner is connected to the side beam.

[0016] In some embodiments, the first-position brake box and the second-position brake box are located between a pair of side beams, and the first-position brake box and the second-position brake box have an operation and maintenance area on the side facing the side beams.

[0017] In some embodiments, at least one of the first-position brake box and the second-position brake box includes a box frame, and the braking device includes a braking function component fixed to the box frame, a box pipeline, and a fluid control device.

[0018] In some embodiments, at least one of the first-position brake box and the second-position brake box is arranged in three layers in the height direction, with the upper layer arranging the box pipes and fluid control device, the middle layer arranging the braking function components, and the lower layer arranging the electrical transmission device.

[0019] This application also provides a rail vehicle including the aforementioned equipment hoisting system.

[0020] In some embodiments, the rail vehicle further includes a first-end bogie, a second-end bogie, and undercar electrical equipment. The first-end bogie is located on one side of the first-end brake box, the second-end bogie is located on one side of the second-end brake box, and the undercar electrical equipment is longitudinally distributed between the first-end brake box and the second-end brake box, and is located under the longitudinal tube bank.

[0021] Compared to the aforementioned background technology, the equipment hoisting system provided in this application mainly includes a first-position brake box, a second-position brake box, and a longitudinal pipe bank. Both the first-position brake box and the second-position brake box integrate braking devices. The first-position brake box and the second-position brake box are installed as independent integrated modules at both ends of the rail vehicle. The two ends of the longitudinal pipe bank are connected to the first-position brake box and the second-position brake box respectively to realize the air circuit connection between the first-position brake box and the second-position brake box.

[0022] In the traditional installation of equipment under rail vehicles, braking devices and other components are typically installed one by one, resulting in a cumbersome and inefficient process. This decentralized installation method not only increases construction time and costs but also reduces space utilization, increases vehicle weight, and affects the overall performance and economy of the rail vehicle.

[0023] The core of this system lies in integrating the braking equipment into two brake boxes: one for the first position and one for the second position. This integrated design consolidates the previously scattered braking devices into a single module, simplifying the installation process. The first and second position brake boxes, as independent modules, are installed at opposite ends of the rail vehicle. This modular installation method makes equipment installation more convenient and efficient. By pre-integrating the braking equipment into the boxes, pre-assembly can be performed under the vehicle, reducing the complexity and time consumption of on-site installation.

[0024] In addition, the system includes a longitudinal pipe bank, with its two ends connected to the first-position brake box and the second-position brake box respectively, ensuring air circuit connectivity between the two brake boxes. This design not only simplifies the air circuit connection process but also improves the system's reliability and stability. The longitudinal pipe bank connection achieves integrated air circuitry for the braking equipment, further reducing on-site installation procedures and time.

[0025] Based on the above structural and process descriptions, it can be seen that the equipment hoisting system has at least the following beneficial effects: By integrating the braking equipment into independent single-position brake boxes and two-position brake boxes, and achieving air circuit connection through longitudinal pipe rows, the equipment hoisting system realizes pre-assembly under the vehicle and integrated loading onto the vehicle, effectively improving construction efficiency, reducing installation procedures, increasing space utilization, and solving the problems of cumbersome and inefficient installation in traditional installation methods.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0037] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the equipment hoisting system provided in an embodiment of this application. Figure 2 A schematic diagram of the equipment hoisting system provided in the embodiments of this application.

[0039] In a first specific embodiment, the equipment hoisting system provided by this application mainly includes a first-position brake box 1, a second-position brake box 2, and a longitudinal pipe array 3. Both the first-position brake box 1 and the second-position brake box 2 are integrated with braking devices. The first-position brake box 1 and the second-position brake box 2 are installed as independent integral modules at both ends of the rail vehicle. The two ends of the longitudinal pipe array 3 are connected to the first-position brake box 1 and the second-position brake box 2 respectively to realize the air circuit connection between the first-position brake box 1 and the second-position brake box 2.

[0040] In the traditional installation of equipment under rail vehicles, braking devices and other components are typically installed one by one, resulting in a cumbersome and inefficient process. This decentralized installation method not only increases construction time and costs but also reduces space utilization, increases vehicle weight, and affects the overall performance and economy of the rail vehicle. To address these issues, this application provides an innovative equipment hoisting system.

[0041] The core of this system lies in integrating the braking equipment into two separate end brake boxes: one at the first position and one at the second position. This integrated design consolidates the previously dispersed braking devices into a single module, simplifying the installation process. The first-position brake box 1 and the second-position brake box 2 are installed as independent modules at both ends of the rail vehicle, respectively. This modular installation method makes equipment installation more convenient and efficient. By pre-integrating the braking equipment into the boxes, pre-assembly can be performed under the vehicle, reducing the complexity and time consumption of on-site installation.

[0042] In addition, the system includes a longitudinal pipe bank 3, whose two ends are connected to the first-position brake box 1 and the second-position brake box 2 respectively, ensuring air circuit connectivity between the two brake boxes. This design not only simplifies the air circuit connection process but also improves the system's reliability and stability. The connection of the longitudinal pipe bank 3 achieves integrated air circuitry for the braking equipment, further reducing on-site installation procedures and time.

[0043] Based on the above structural and process descriptions, it can be seen that the equipment hoisting system has at least the following beneficial effects: By integrating the braking equipment into independent single-position brake box 1 and double-position brake box 2, and achieving air circuit connection through longitudinal pipe row 3, the equipment hoisting system realizes pre-assembly under the vehicle and integrated loading onto the vehicle, effectively improving construction efficiency, reducing installation procedures, improving space utilization, and solving the problems of cumbersome and inefficient installation in traditional installation methods.

[0044] It should be noted that the equipment hoisting system provided in this application is particularly suitable for equipment under the vehicle, and the "under the vehicle" referred to here actually refers to the area under the passenger compartment of the vehicle, which is different from the area under the entire vehicle.

[0045] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a longitudinal pipe bank provided in an embodiment of this application.

[0046] In some embodiments, the longitudinal tube bank 3 includes:

[0047] The main body of the pipe bank 31 is located between the first-position brake box 1 and the second-position brake box 2;

[0048] Multiple hoses 32 are distributed at both ends of the main body 31 of the pipe bank. The hoses 32 are connected to the air ports of the main body 31 of the pipe bank one by one. The hoses 32 are also connected to the first-position brake box 1 or the second-position brake box 2.

[0049] In this embodiment, the longitudinal pipe array 3 is designed to achieve air passage connection between the first-position brake box 1 and the second-position brake box 2. To this end, the longitudinal pipe array 3 includes a key component—the pipe array body 31. The pipe array body 31 is located between the first-position brake box 1 and the second-position brake box 2, and its main function is to serve as the main air passage, ensuring smooth air passage connection between the two brake boxes. Through the pipe array body 31, the air passage connection between the braking devices becomes more stable and efficient, providing a reliable air source transmission path for the braking system of the rail vehicle.

[0050] Furthermore, to enhance the flexibility and adaptability of the air circuit connection, the longitudinal pipe bank 3 also includes multiple hoses 32. These hoses 32 are distributed at both ends of the pipe bank body 31 and connect to the air ports of the pipe bank body 31 one by one. The design of the hoses 32 makes the air circuit connection more flexible and can adapt to different installation environments and equipment layouts. At the same time, the hoses 32 are also connected to the single-end brake box 1 or the double-end brake box 2, further ensuring the connectivity and reliability of the air circuit. This hose connection method not only improves the overall performance of the system, but also provides convenience for installation and maintenance, making the air circuit connection more stable and easier to operate.

[0051] Specifically, the first end of the pipe bank body 31 is connected to the air passage of the first-position brake box 1 through the first type of hose 32, and the second end of the pipe bank body 31 is connected to the air passage of the second-position brake box 2 through the second type of hose 32.

[0052] In one specific implementation, the equipment hoisting system is an integrated hoisting system consisting of "equipment housing + central pipe row module + flexible connection".

[0053] This hoisting system analyzes and reorganizes the braking components based on their size / weight, functional relevance, and location requirements, integrating them into two integrated equipment housings (one-position brake housing 1 and two-position brake housing 2) and a central pipe array module (longitudinal pipe array 3). The two integrated equipment housings and the pipe array module employ a flexible connection, enabling pre-assembly of the braking components under the vehicle and integrated installation. This flexible connection solves the problem of air circuit matching between modules, allowing for complete assembly and disassembly of modules without interference, and avoiding the need for passive disassembly of other components during assembly. This integrated hoisting system enables multiple processes to proceed in parallel, greatly improving construction efficiency.

[0054] In some embodiments, the pipe bank body 31 includes:

[0055] Longitudinal pipes 311 extend longitudinally between the first-position brake box 1 and the second-position brake box 2, and multiple longitudinal pipes 311 are distributed laterally perpendicular to the extension direction of the pipes.

[0056] The connecting row 312 extends laterally in the direction in which multiple longitudinal pipes 311 are distributed. The connecting row 312 is connected to the longitudinal pipes 311 and is installed on the rail vehicle.

[0057] In this embodiment, the structural design of the pipe array body 31 includes two key parts: longitudinal pipes 311 and connecting pipes 312. The longitudinal pipes 311 extend longitudinally between the first-position brake box 1 and the second-position brake box 2, forming the main channel of the air circuit. Multiple longitudinal pipes 311 are distributed laterally perpendicular to the extension direction of the pipes. This design allows the air circuit system to better adapt to the spatial layout of the rail vehicle, improving the flexibility and adaptability of the air circuit.

[0058] The connecting strip 312 extends laterally along the direction of the multiple longitudinal pipes 311, and its main function is to connect the various longitudinal pipes 311 together to form an integrated pipe strip structure. Through the connecting strip 312, the entire pipe strip body 31 is installed onto the rail vehicle, achieving integrated onboard installation. This integrated design simplifies the installation process, improves construction efficiency, and allows the entire pneumatic system to be more easily integrated into the rail vehicle, enhancing the system's stability and reliability.

[0059] Please refer to Figure 4 , Figure 4This is a schematic diagram of the support structure provided in an embodiment of this application.

[0060] In some embodiments, at least one of the first-position brake box 1 and the second-position brake box 2 is provided with a support structure 4, which is mounted on the side beam 01 of the rail vehicle.

[0061] In this embodiment, the design of the first-position brake box 1 and the second-position brake box 2 introduces an innovative support structure 4. This support structure 4 is installed in at least one brake box, and its main function is to fix the brake box to the side beam 01 of the rail vehicle. Compared with the traditional crossbeam suspension method, the use of the support structure 4 realizes the transformation from crossbeam suspension to side beam support. This transformation not only simplifies the installation process but also reduces the dependence on the car body structure, making the installation of the brake box more flexible and efficient.

[0062] By adopting the side beam support structure 4, the rail vehicle eliminates the need for additional crossbeams on the car body to support the brake box. This improvement significantly reduces the car body weight, achieving weight reduction. Weight reduction not only improves the operating efficiency and reduces energy consumption of the rail vehicle but also enhances its overall economic efficiency. Furthermore, reducing the use of crossbeams provides greater flexibility in the design and manufacturing of the rail vehicle, allowing for a more rational spatial layout and further improving space utilization. This innovative support structure 4 provides a more efficient and economical solution for the installation of undercarriage equipment on rail vehicles.

[0063] In some cases, the first-position brake box 1 and the second-position brake box 2 are located between a pair of side beams 01. The lateral sides of the first-position brake box 1 are both suspended on the side beams 01 of the rail vehicle via the support structure 4, and the lateral sides of the second-position brake box 2 are both suspended on the side beams 01 of the rail vehicle via the support structure 4.

[0064] In some embodiments, the support structure 4 includes a lifting lug 41 and a liner 42. The side beam 01 is provided with a process hole 011 for the lifting lug 41 to move from the lower side of the side beam 01 to the upper side of the side beam 01. The liner 42 is located between the upper side of the side beam 01 and the lifting lug 41. The lifting lug 41 is connected to the liner 42, and the liner 42 is connected to the side beam 01.

[0065] In this embodiment, the specific structure of the support structure 4 includes two key components: a lifting lug 41 and a liner plate 42. The lifting lug 41 is the connection point of the support structure 4. It is connected to the frame 6 of the brake box and moves from the lower side to the upper side of the side beam 01 through the process hole 011 on the side beam 01, so as to lift the lifting lug 41 above the mounting surface of the side beam 01. This design allows the brake box to be easily installed on the side beam 01, and also facilitates the disassembly of the brake box.

[0066] The liner 42 is located between the upper side of the side beam 01 and the lifting lug 41. By inserting the liner 42 between the side beam 01 and the lifting lug 41, and ensuring that the length of the liner 42 exceeds the size of the process hole 011, the liner 42 serves as a support and connector. The upper surface of the liner 42 supports the lifting lug 41, and the lifting lug 41 is connected to the liner 42, ensuring a secure connection between the brake box and the side beam 01. The lower surface of the liner 42 overlaps the mounting surface of the side beam 01, and the connection between the liner 42 and the side beam 01 further enhances the stability and load-bearing capacity of the entire support structure 4.

[0067] Through this structural design, the support structure 4 can effectively transfer the weight of the brake box to the side beam 01, ensuring that the brake box remains stable during the operation of the rail vehicle, and also providing reliable support for the braking system of the rail vehicle.

[0068] Specifically, the support structure 4 also includes bolts 43, washers 44 and nuts 45. The side beam 01 is provided with mounting holes 012. The liner 42 and the side beam 01 are fastened by bolts 43 in the mounting holes 012 and by washers 44 and nuts 45 connected to the bolts 43.

[0069] Please refer to Figure 5 , Figure 5 This is a schematic diagram of a brake box provided in an embodiment of this application.

[0070] In some embodiments, the first-position brake box 1 and the second-position brake box 2 are located between a pair of side beams 01, and the first-position brake box 1 and the second-position brake box 2 are provided with an operation and maintenance area 5 on the side facing the side beams 01.

[0071] In this embodiment, the first-position brake box 1 and the second-position brake box 2 are cleverly arranged between a pair of side beams 01 of the rail vehicle. The side beams 01 support the brake boxes, thereby enabling the pair of side beams 01 to support the equipment hoisting system. This layout not only optimizes the utilization of the space under the vehicle but also provides convenience for operation and maintenance.

[0072] On the side facing the side beam 01, the brake box features a specially designed operation and maintenance area 5, making daily operation and maintenance more efficient. The operation and maintenance area 5 is designed in two forms: exposed and covered. The exposed form allows for quick and direct access to the components requiring operation or maintenance, suitable for rapid handling in emergencies. The covered form provides additional protection for the components, preventing dust and foreign objects from entering, while also making the under-vehicle equipment look cleaner. Regardless of the form, the components requiring daily operation and maintenance are located on the side of the brake box near the vehicle body side beam. This design allows personnel to perform related work from the side beam without entering the vehicle, greatly improving operational convenience and safety, while also reducing maintenance costs and time.

[0073] In some embodiments, at least one of the single-position brake box 1 and the two-position brake box 2 includes a box frame 6, and the braking device includes a braking function component 7 fixed to the box frame 6, a box pipeline 8, and a fluid control device 9.

[0074] In this embodiment, the housing frame 6 serves as the basic support structure for the brake housing, providing a robust framework for the installation of the braking device. The core components of the braking device include the braking function components 7, the housing piping 8, and the fluid control device 9, all of which are fixed to the housing frame 6, ensuring the stability and reliability of the device.

[0075] The braking function component 7 can be a braking function component or module responsible for realizing the braking function of the rail vehicle. Connected to the rail vehicle's braking system, it controls the deceleration or stopping of the rail vehicle and is the most critical part of the brake box. The box piping 8 is responsible for the air passage connection, connecting the braking function component 7 to other pneumatic systems of the rail vehicle, ensuring smooth airflow throughout the braking system, thereby guaranteeing the normal operation of the braking function. The fluid control device 9 can be a shut-off valve or similar device used to control the opening and closing of the air passage, and to regulate the pressure and flow rate of the airflow, thereby achieving precise control of the braking system. Through the coordinated work of these components, the brake box can efficiently and stably complete its braking task, providing a solid guarantee for the safe operation of the rail vehicle.

[0076] In some cases, the braking function component 7 mainly includes an air cylinder, and the fluid control device 9 mainly includes a differential pressure valve and a balance valve. Specifically, the operation and maintenance area 5 is equipped with a shut-off valve, a BP rescue conversion device requiring door opening for maintenance, an air circuit board module requiring operation and maintenance, a wheel flange lubrication device requiring oil filling and maintenance, an outdoor air conditioning unit requiring heat dissipation, a brake release display requiring observation, and a single-phase inverter power supply requiring door opening for maintenance and heat dissipation. In addition, depending on the rail vehicle, the following may be installed in sequence: a safety interlock box requiring operation, and a sand-spreading control box requiring maintenance.

[0077] In some embodiments, at least one of the one-position brake box 1 and the two-position brake box 2 is arranged in three layers in the height direction, with the box pipe 8 and fluid control device 9 arranged in the upper layer, the brake function component 7 arranged in the middle layer, and the electrical transmission device arranged in the lower layer.

[0078] In this embodiment, the design of the single-position brake box 1 and the two-position brake box 2 adopts a layered arrangement in the vertical direction to achieve efficient space utilization and reasonable functional zoning. Specifically, the interior of the brake box is divided into three layers: an upper layer, a middle layer, and a lower layer. The upper layer mainly houses the box pipes 8 and fluid control devices 9, i.e., pipe valves. These components are responsible for ensuring the connectivity of the air passages and the control of the fluid, ensuring that the braking system can stably transmit airflow and regulate pressure. The middle layer is used to house the braking function components 7, i.e., the braking equipment. As the core part of the brake box, the braking function components 7 undertake the important task of realizing the braking function of the rail vehicle. Its location in the middle layer facilitates connection and collaborative work with other related components. The lower layer houses the electrical transmission devices, i.e., wiring harnesses and electrical connectors, responsible for processing and transmitting electrical signals related to the braking system, ensuring the smooth realization of the electrical control and monitoring functions of the braking system. This layered arrangement not only makes the internal structure of the brake box clearer and more orderly, but also facilitates the installation, maintenance, and repair of each component, while improving the stability and reliability of the entire braking system.

[0079] In one specific implementation, the installation process of the equipment hoisting system is described below.

[0080] First, the first-position brake box 1 and the second-position brake box 2 are respectively mounted on a pair of side beams 01 of the rail vehicle. These two brake boxes are stably fixed by the mounting structure 4, ensuring their stability during rail vehicle operation. Next, the two ends of the longitudinal pipe array 3 are connected to the first-position brake box 1 and the second-position brake box 2 respectively, to achieve air passage connection between the two brake boxes. The longitudinal pipe array 3 includes a main body 31 and multiple flexible hoses 32. The main body 31 is located between the two brake boxes, achieving an orderly arrangement without any crossing between pipes. The flexible hoses 32 are connected one by one to the air ports of the main body 31 and then to the corresponding brake box. This flexible connection solves the error problem, eliminating the need for further fitting of the interface connection pipes.

[0081] Before mounting the first-position brake box 1 and the second-position brake box 2 onto the vehicle, it is necessary to ensure that the braking function components 7, box piping 8, and fluid control device 9 within the brake box are correctly installed and fixed to the box frame 6. The equipment is installed piecemeal to form two independent brake boxes with specific functions. Each brake box can be installed entirely on the vehicle body, allowing for complete assembly and disassembly. The brake boxes perform functions such as under-vehicle braking, air storage, brake release display, and air circuit cutoff. In addition, components requiring daily operation, inspection, and maintenance are located on the side of the brake box near the vehicle body side beam 01 to facilitate daily operation and maintenance without needing to enter under the vehicle.

[0082] This application also provides a rail vehicle including the aforementioned equipment hoisting system. The rail vehicle should possess all the beneficial effects of the aforementioned equipment hoisting system.

[0083] It should be noted that conventional rail vehicles are based on a crossbeam load-bearing structure, with various sizes and dispersed layouts of undercarriage components, resulting in significant differences in installation structure, large space occupation, and low space utilization.

[0084] Pipelines, pipe fittings, valves, and other components need to be installed one by one on the vehicle chassis. Then, the scattered equipment is hoisted and installed one by one. Finally, the connecting pipes between the longitudinal pipelines and the equipment are installed one by one to meet the air requirements of each piece of equipment. This involves multiple processes that cannot be carried out simultaneously. The installation of components is scattered and complicated, resulting in low construction efficiency.

[0085] When connecting air supply ducts to equipment interface terminals, rigid pipe connections are generally used. Due to the accumulation of installation errors, problems often arise where the two terminal interfaces cannot be properly connected or where the airtightness is poor after connection. In this case, it is necessary to continuously adjust the position of the middle pipe interface or temporarily adjust the length and angle of the connecting pipe for fitting. This fitting process is time-consuming and labor-intensive, and the installation quality is not stable enough.

[0086] In the early stages, pipelines, valves, and other components are installed piecemeal. When the equipment needs to be disassembled for inspection and maintenance, it cannot be directly removed due to obstruction by other equipment or local pipelines. Individual equipment or pipelines must be disassembled first before the components can be removed for inspection and maintenance, resulting in poor maintainability.

[0087] To address these issues, the rail vehicle provided in this application analyzes and integrates braking principles and installation components to form a single-end brake box 1, a two-end brake box 2, and a longitudinal pipe array 3. The single-end brake box 1 and the two-end brake box 2 are flexibly connected to the longitudinal pipe array 3, and the braking, operation, display, and air supply functions are realized through the brake boxes.

[0088] The first-position brake box 1 and the second-position brake box 2 adopt a side beam support form, which changes the traditional crossbeam suspension method and forms a new type of support structure 4. This structure eliminates the need for vehicle body crossbeams, thereby reducing the weight of the vehicle body. At the same time, it avoids the scattered installation of equipment, making the equipment installation more compact, saving a lot of space, and improving the overall integrity and modularity.

[0089] The design of the central longitudinal pipe array 3 allows for complete assembly and disassembly, avoiding the need for individual installation of each pipe in the central pipeline, greatly simplifying the installation process and improving construction efficiency. Furthermore, fluid control devices 9, such as shut-off valves, are integrated into the equipment housing, eliminating the need for separate shut-off valves in the central pipeline and further simplifying the system structure.

[0090] The equipment housing and the central longitudinal pipe array 3 are connected by flexible hoses, effectively solving the fitting problems caused by errors at the terminal air interface of the two, and improving the stability and reliability of the installation. At the same time, the installation and disassembly of the equipment housing and the longitudinal pipe array 3 are independent and do not interfere with each other, solving the problem of not being able to disassemble the pipelines individually due to equipment obstruction, which greatly improves the ease of maintenance. The pipelines under the vehicle are arranged in an orderly manner according to functional requirements, and there is no intersection between the longitudinal pipelines, further improving the overall performance and maintenance efficiency of the system.

[0091] Please refer to Figure 6 , Figure 6 This is a layout diagram of the equipment hoisting system provided in the embodiments of this application in a rail vehicle.

[0092] In some embodiments, the rail vehicle further includes a first-end bogie 02, a second-end bogie 03, and undercar electrical equipment 04. The first-end bogie 02 is located on one side of the first-end brake box 1, the second-end bogie 03 is located on one side of the second-end brake box 2, and the undercar electrical equipment 04 is longitudinally distributed between the first-end brake box 1 and the second-end brake box 2. The undercar electrical equipment 04 is located on the underside of the longitudinal tube bank 3.

[0093] In this embodiment, the bogies, as an important component of the rail vehicle, are responsible for supporting the weight of the rail vehicle and guiding it along the track. Their layout corresponds to the brake boxes, resulting in a more balanced weight distribution for the rail vehicle, which helps improve its stability and operational performance. During operation, the first-position bogie 02 is controlled by the first-position brake box 1, and the second-position bogie 03 is controlled by the second-position brake box 2.

[0094] The undercar electrical equipment 04 is longitudinally distributed between the first-position brake box 1 and the second-position brake box 2, and located below the longitudinal pipe row 3. This layout allows the electrical equipment to cooperate with the braking system, facilitating the coordinated operation of the electrical control and braking control of the rail vehicle. The undercar electrical equipment 04 is responsible for providing power supply, signal transmission, and control functions for the rail vehicle. Its longitudinal distribution and placement below the longitudinal pipe row 3 optimizes the spatial layout of the rail vehicle, improves equipment integration, and enhances maintenance efficiency.

[0095] In the specific embodiments of this application, the installation and layout of the equipment hoisting system are carefully designed to ensure its efficiency and reliability. Firstly, the installation positions of the first-position brake box 1 and the second-position brake box 2 are optimized to achieve the best weight distribution and functional performance at both ends of the rail vehicle. This layout not only helps improve the operational stability of the rail vehicle but also reduces vibration and noise generated during operation to a certain extent, thereby enhancing the passenger experience.

[0096] The use of the support structure 4 was carefully considered during installation. The design of the lifting lug 41 and the liner 42 not only ensures a secure connection between the brake box and the side beam 01, but also takes into account the ease of installation and disassembly. By setting process holes 011 on the side beam 01, the lifting lug 41 can be easily moved from the lower side to the upper side of the side beam 01. This design greatly simplifies the installation steps and reduces installation time and labor intensity. At the same time, the use of the liner 42 also improves the load-bearing capacity of the brake box, ensuring that it can withstand various loads and impacts during the operation of the rail vehicle.

[0097] During the operation of the rail vehicle, the coordinated operation of the first-end bogie 02 and the second-end bogie 03 with the brake box has been fully considered. The layout of the bogies corresponds to the brake box, resulting in a more balanced weight distribution of the rail vehicle, which helps to improve the stability and running performance of the rail vehicle. During operation, the first-end bogie 02 is controlled by the first-end brake box 1, and the second-end bogie 03 is controlled by the second-end brake box 2. This control method enables precise braking and steering of the rail vehicle, improving the handling and safety of the rail vehicle.

[0098] In summary, the equipment hoisting system and rail vehicle of this application have fully considered various factors during design and implementation to ensure their efficient, stable, and reliable operation. By optimizing the installation layout, improving structural strength, and enhancing collaborative control capabilities, this application provides strong technical support and assurance for the operation of the rail vehicle.
