Description

Technical Field

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

[0002] The installation of brake equipment is a key step in the installation of undercarriage equipment on rail vehicles. The traditional installation method usually requires the brake equipment to be installed one by one on the vehicle chassis, and then other scattered equipment is hung and installed one by one, and finally the pipelines are connected to the equipment one by one.

[0003] In the prior art, the installation process of brake equipment and other undercarriage components is cumbersome and inefficient. Since the brake equipment needs to be installed one by one, and then other scattered equipment is hung one by one, and finally the pipeline is connected, the entire installation process involves multiple steps and cannot be carried out simultaneously. The installation of each component is scattered and complicated, resulting in low construction efficiency, increasing construction time and cost. In addition, this decentralized installation method also results in low space utilization, increased vehicle weight, and affects the overall performance and economy of the rail vehicle. Summary of the invention

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

[0015] In some embodiments, the supporting structure includes a lifting ear and a lining plate. The side beam is provided with a process hole for the lifting ear to move from the lower side of the side beam to the upper side of the side beam. The lining plate is located between the upper side of the side beam and the lifting ear. The lifting ear is connected to the lining plate, and the lining plate is connected to the side beam.

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

[0017] In some embodiments, at least one of the first-end brake box and the second-end 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-end brake box and the second-end brake box is arranged in three layers in the height direction, with the box pipeline and fluid control device arranged on the upper layer, the braking function components arranged in the middle layer, and the electrical transmission device arranged on the lower layer.

[0019] The present application also provides a rail vehicle, comprising the above-mentioned equipment lifting system.

[0020] In some embodiments, the rail vehicle also includes a first-end bogie, a second-end bogie and under-vehicle 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, the under-vehicle electrical equipment is longitudinally distributed between the first-end brake box and the second-end brake box, and the under-vehicle electrical equipment is located on the lower side of the longitudinal pipe row.

The first-end brake box and the second-end brake box are independent integral modules, which are installed at both ends of the rail vehicle respectively. This modular installation method makes the installation of the equipment more convenient and efficient. By pre-integrating the brake equipment into the box, it can be pre-assembled under the vehicle, realizing pre-assembly under the vehicle, thereby reducing the complexity and time consumption of on-site installation.

[0024] In addition, the system also includes a longitudinal pipe row, whose two ends are connected to the first-end brake box and the second-end brake box respectively, ensuring the air circuit connection between the two brake boxes. This design not only simplifies the air circuit connection process, but also improves the reliability and stability of the system. Through the connection of the longitudinal pipe row, the air circuit integration of the brake equipment is realized, further reducing the process and time of on-site installation.

[0025] Combined with the above structure and process description, it can be seen that the equipment hoisting system has at least the following beneficial effects: the equipment hoisting system integrates the braking equipment into independent first-end brake boxes and second-end brake boxes, and realizes air path connectivity through longitudinal pipe rows, thereby realizing under-vehicle pre-assembly and integrated loading, effectively improving construction efficiency, reducing installation procedures, and improving space utilization, solving the problems of cumbersome installation and low efficiency in traditional installation methods.

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of an equipment hoisting system provided in an embodiment of the present application, Figure 2 A schematic diagram of the equipment lifting system provided in an embodiment of the present application.

[0039] In the first specific implementation manner, the equipment lifting system provided by the implementation scheme of the present application mainly includes a first-end brake box 1, a second-end brake box 2 and a longitudinal pipe row 3. The first-end brake box 1 and the second-end brake box 2 are both integrated with braking equipment. The first-end brake box 1 and the second-end brake box 2 are respectively installed at the two ends of the rail vehicle as independent integral modules; the two ends of the longitudinal pipe row 3 are respectively connected to the first-end brake box 1 and the second-end brake box 2 to realize the air circuit connection between the first-end brake box 1 and the second-end brake box 2.

[0040] In the traditional installation process of undercarriage equipment of rail vehicles, the installation of brake equipment and other components usually needs to be carried out one by one, which makes the installation process cumbersome and inefficient. This decentralized installation method not only increases construction time and cost, but also reduces space utilization, increases vehicle weight, and affects the overall performance and economy of rail vehicles. In order to solve these problems, the present application provides an innovative equipment lifting system.

[0041] The core of the system is to integrate the brake equipment into the first-end brake box 1 and the second-end brake box 2. This integrated design allows the originally dispersed brake equipment to be concentrated in one module, simplifying the installation steps. The first-end brake box 1 and the second-end brake box 2 are independent integral modules, which are installed at both ends of the rail vehicle respectively. This modular installation method makes the installation of the equipment more convenient and efficient. By pre-integrating the brake equipment into the box, it can be pre-assembled under the vehicle, realizing pre-assembly under the vehicle, thereby reducing the complexity and time consumption of on-site installation.

[0042] In addition, the system also includes a longitudinal pipe row 3, the two ends of which are respectively connected to the first-end brake box 1 and the second-end brake box 2, ensuring the air path connection between the two brake boxes. This design not only simplifies the air path connection process, but also improves the reliability and stability of the system. Through the connection of the longitudinal pipe row 3, the air path integration of the brake equipment is realized, further reducing the process and time of on-site installation.

[0043] Combined with the above structure and process description, it can be seen that the equipment hoisting system has at least the following beneficial effects: the equipment hoisting system integrates the braking equipment into independent first-end brake box 1 and second-end brake box 2, and realizes air path connection through longitudinal pipe row 3, thereby realizing under-vehicle pre-assembly and integrated loading, effectively improving construction efficiency, reducing installation procedures, improving space utilization, and solving the problems of cumbersome installation and low efficiency in traditional installation methods.

[0044] It should be noted that the equipment lifting system provided in the implementation scheme of the present application is particularly suitable for under-vehicle equipment, and the under-vehicle referred to here actually refers to the underside of the vehicle passenger compartment, which is different from the underside of the entire vehicle.

[0045] Please refer to Figure 3 , Figure 3 A schematic diagram of a longitudinal tube row provided in an embodiment of the present application.

[0046] In some embodiments, the longitudinal tube row 3 comprises:

[0047] The pipe row body 31 is arranged between the first end brake box 1 and the second end brake box 2;

[0048] A plurality of hoses 32 are distributed at both ends of the tube row body 31 . The hoses 32 are connected to the air ports of the tube row body 31 one by one. The hoses 32 are also connected to the first-end brake box 1 or the second-end brake box 2 .

[0049] In this embodiment, the longitudinal pipe row 3 is designed to achieve air path connection between the first-end brake box 1 and the second-end brake box 2. To this end, the longitudinal pipe row 3 includes a key component, the pipe row body 31. The pipe row body 31 is located between the first-end brake box 1 and the second-end brake box 2. Its main function is to serve as the main channel of the air path to ensure that the air path between the two brake boxes can be smoothly connected. Through the pipe row body 31, the air path connection between the brake devices becomes more stable and efficient, providing a reliable air source transmission path for the brake system of the rail vehicle.

[0050] In addition, in order to enhance the flexibility and adaptability of the gas circuit connection, the longitudinal pipe row 3 also includes a plurality of hoses 32. These hoses 32 are distributed at both ends of the pipe row body 31 and are connected to the gas ports of the pipe row body 31 one by one. The design of the hoses 32 makes the gas 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 first-end brake box 1 or the second-end brake box 2, further ensuring the connectivity and reliability of the gas circuit. This hose connection method not only improves the overall performance of the system, but also provides convenience for installation and maintenance, making the gas circuit connection more stable and easy to operate.

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

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

[0053] This hoisting system analyzes and reorganizes the brake components according to their size / weight, functional relevance, and location requirements, and integrates them into two integrated equipment boxes (first-end brake box 1, second-end brake box 2) and a middle pipe row module (longitudinal pipe row 3). The two integrated equipment boxes and the pipe row module are connected in a flexible manner, which enables the brake components to be pre-assembled off the vehicle and integrated onto the vehicle. The flexible connection solves the problem of gas path research and matching between modules, and enables the modules to be assembled and disassembled without interfering with each other, avoiding the problem of passive disassembly of other components when the components are assembled. This integrated hoisting system realizes multiple processes in parallel, greatly improving construction efficiency.

[0054] In some embodiments, the tube array body 31 includes:

[0055] A longitudinal pipeline 311 extends longitudinally between the first-end brake box 1 and the second-end brake box 2, and a plurality of longitudinal pipelines 311 are distributed in a transverse direction perpendicular to the extending direction of the pipeline;

[0056] The connection row 312 extends transversely in the direction in which the plurality of longitudinal pipelines 311 are distributed. The connection row 312 is connected to the longitudinal pipelines 311 . The connection row 312 is installed on the rail vehicle.

[0057] In this embodiment, the structural design of the pipe row body 31 includes two key parts: a longitudinal pipe 311 and a connecting row 312. The longitudinal pipe 311 extends longitudinally between the first-end brake box 1 and the second-end brake box 2 to form the main passage of the gas circuit. Multiple longitudinal pipes 311 are distributed in a lateral direction perpendicular to the extension direction of the pipes. This design enables the gas circuit system to better adapt to the spatial layout of the rail vehicle and improves the flexibility and adaptability of the gas circuit.

[0058] The connecting row 312 extends transversely in the direction in which the plurality of longitudinal pipelines 311 are distributed, and its main function is to connect the longitudinal pipelines 311 together to form an integral pipe row structure. Through the connecting row 312, the entire pipe row body 31 is installed on the rail vehicle to achieve integrated boarding. This integrated design simplifies the installation process, improves construction efficiency, enables the entire gas circuit system to be more conveniently integrated into the rail vehicle, and enhances the stability and reliability of the system.

[0059] Please refer to Figure 4 , Figure 4A schematic diagram of the supporting structure provided in an embodiment of the present application.

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

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

[0062] By adopting the side beam hanging structure 4, the rail vehicle does not need to set an additional crossbeam on the vehicle body to support the brake box. This improvement significantly reduces the weight of the vehicle body and achieves weight reduction of the vehicle body. The weight reduction of the vehicle body not only improves the operating efficiency of the rail vehicle, reduces energy consumption, but also improves the overall economy of the rail vehicle. In addition, reducing the use of crossbeams also provides greater flexibility for the design and manufacture of rail vehicles, making the spatial layout more reasonable and further improving the space utilization of rail vehicles. This innovative hanging structure 4 provides a more efficient and economical solution for the installation of under-vehicle equipment on rail vehicles.

[0063] In some cases, the first-end brake box 1 and the second-end brake box 2 are located between a pair of side beams 01, and both lateral sides of the first-end brake box 1 are hung on the side beams 01 of the rail vehicle through a supporting structure 4, and both lateral sides of the second-end brake box 2 are hung on the side beams 01 of the rail vehicle through a supporting structure 4.

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

[0065] In this embodiment, the specific structure of the hanging structure 4 includes two key components: a lifting lug 41 and a lining plate 42. The lifting lug 41 is the connection point of the hanging structure 4, which is connected to the box frame 6 of the brake box, and is moved from the lower side of the side beam 01 to the upper side through the process hole 011 on the side beam 01, so as to lift the lifting lug 41 above the installation surface of the side beam 01. This design allows the brake box to be easily installed on the side beam 01, and also provides convenience for the removal of the brake box.

[0066] The lining plate 42 is located between the upper side of the side beam 01 and the lifting lug 41. The lining plate 42 is inserted between the side beam 01 and the lifting lug 41. At the same time, the length of the lining plate 42 must exceed the size of the process hole 011. The lining plate 42 plays a supporting and connecting role. The upper plane of the lining plate 42 supports the lifting lug 41, and the lifting lug 41 is connected to the lining plate 42, ensuring a firm connection between the brake box and the side beam 01. The lower plane of the lining plate 42 overlaps the mounting surface of the side beam 01. The connection between the lining plate 42 and the side beam 01 further enhances the stability and load-bearing capacity of the entire supporting structure 4.

[0067] Through this structural design, the supporting 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, while also providing reliable support for the braking system of the rail vehicle.

[0068] Specifically, the supporting structure 4 also includes bolts 43, washers 44 and nuts 45. The side beam 01 is provided with a mounting hole 012. The lining plate 42 and the side beam 01 are fastened by setting bolts 43 in the mounting hole 012 and connecting them with the bolts 43 with washers 44 and nuts 45.

[0069] Please refer to Figure 5 , Figure 5 A schematic diagram of a brake box provided in an embodiment of the present application.

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

[0071] In this embodiment, the first-end brake box 1 and the second-end brake box 2 are cleverly arranged between a pair of side beams 01 of the rail vehicle, and the side beams 01 support the equipment hoisting system by supporting the brake box. This layout not only optimizes the use 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 is specially designed with an operation and maintenance area 5, making daily operation and maintenance work more efficient. The design of the operation and maintenance area 5 takes into account two forms: an exposed form and a cover-shielded form. The exposed form facilitates quick and direct access to the parts that need to be operated or repaired, and is suitable for rapid processing in emergency situations. The cover-shielded form provides additional protection for the parts to prevent the intrusion of dust and foreign objects, and also makes the appearance of the equipment under the vehicle neater. Regardless of the form, the parts that require daily operation, inspection and maintenance are set on the side of the brake box close to the side beam of the vehicle body. This design allows staff to complete related work on the side beam of the vehicle body without entering the vehicle during daily operation and maintenance, which greatly improves the convenience and safety of operation, and also reduces maintenance costs and time.

[0073] In some embodiments, at least one of the first-end brake box 1 and the second-end 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 box frame 6 serves as the basic support structure of the brake box, providing a solid framework for the installation of the brake device. The core components of the brake device include a brake function component 7, a box pipeline 8, and a fluid control device 9, all of which are fixed to the box frame 6 to ensure the stability and reliability of the device.

[0075] The braking function component 7 can be a braking function component and module, which is responsible for realizing the braking function of the rail vehicle. It is connected to the braking system of the rail vehicle to control the deceleration or stop of the rail vehicle, and is the most critical part of the brake box. The box pipeline 8 is responsible for the connection of the air circuit. It connects the braking function component 7 with other pneumatic systems of the rail vehicle to ensure that the airflow can flow smoothly in the entire braking system, thereby ensuring the normal performance of the braking function. The fluid control device 9 can be a shut-off valve and valve type, which is used to control the opening and closing of the air circuit, and adjust the pressure and flow of the airflow, so as to achieve 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 brake function component 7 mainly includes an air cylinder, and the fluid control device 9 mainly includes a differential pressure valve and a balance valve. In particular, the operation and maintenance area 5 is provided with a cut-off valve, a BP rescue conversion device that needs to be opened for maintenance, a gas circuit board module that needs to be operated and maintained, a wheel rim lubrication device that needs to be oiled and maintained, an air conditioning outdoor unit that needs to be cooled, a brake relief display that needs to be observed, and a single inverter power supply that needs to be opened for maintenance and heat dissipation; in addition, the following can be arranged in order according to the different rail vehicles: a safety interlock box that needs to be operated, and a sand spreading control box that needs to be maintained.

[0077] In some embodiments, at least one of the first-end brake box 1 and the second-end brake box 2 is arranged in three layers in the height direction, with the box pipeline 8 and the fluid control device 9 arranged on the upper layer, the braking 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 first-end brake box 1 and the second-end brake box 2 adopts a layered arrangement in the height direction to achieve efficient use of space and reasonable functional division. Specifically, the interior of the brake box is divided into three layers: the upper layer, the middle layer and the lower layer. The upper layer mainly arranges the box pipeline 8 and the fluid control device 9, that is, the pipeline valve type. These components are responsible for realizing the connection of the air path and the control of the fluid, ensuring that the brake system can stably transmit the airflow and adjust the pressure. The middle layer is used to arrange the brake function component 7, that is, the brake equipment. As the core part of the brake box, the brake function component 7 undertakes the important task of realizing the braking function of the rail vehicle. It is located in the middle layer to facilitate connection and coordination with other related components. The lower layer arranges the electrical transmission device, that is, the wiring harness and the electrical connector, which are responsible for processing and transmitting the electrical signals related to the brake system, ensuring that the electrical control and monitoring functions of the brake system can be smoothly realized. Through this layered arrangement, not only the internal structure of the brake box is clearer and more orderly, but also it provides convenience for the installation, maintenance and overhaul of each component, and also improves the stability and reliability of the entire brake system.

[0079] In a specific implementation, the installation process of the equipment hoisting system is described as follows.

[0080] First, the first-end brake box 1 and the second-end brake box 2 are respectively supported on a pair of side beams 01 of the rail vehicle. The two brake boxes are stably fixed by the supporting structure 4 to ensure that they remain stable during the operation of the rail vehicle. Next, the two ends of the longitudinal pipe row 3 are respectively connected to the first-end brake box 1 and the second-end brake box 2 to achieve air communication between the two brake boxes. The longitudinal pipe row 3 includes a pipe row main body 31 and a plurality of hoses 32. The pipe row main body 31 is arranged between the two brake boxes to achieve an orderly arrangement without crossing the pipelines. The hoses 32 are connected to the air ports of the pipe row main body 31 one by one, and are connected to the corresponding brake boxes. This flexible connection solves the error problem, and there is no need to research and match the interface connection pipeline.

[0081] Before the first-end brake box 1 and the second-end brake box 2 are installed as a whole, it is also necessary to ensure that the brake function components 7, box pipes 8 and fluid control devices 9 in the brake box are correctly installed and fixed on the box frame 6. The equipment is installed in a scattered manner to form two independent brake boxes with specific functions. Each brake box can be installed as a whole on the vehicle body, and the brake box can realize the functions of braking under the vehicle, storing air, brake relief display, and air path cutoff. In addition, the components that require daily operation, inspection and maintenance are set on the side of the brake box close to the side of the vehicle body side beam 01 to facilitate daily operation and inspection and maintenance, and related work can be completed without entering under the vehicle.

[0082] The present application also provides a rail vehicle, comprising the above-mentioned equipment hoisting system. The rail vehicle should have all the beneficial effects of the above-mentioned equipment hoisting system.

[0083] It should be noted that conventional rail vehicles are based on a car body crossbeam bearing structure, with components under the vehicle of varying sizes and dispersed layouts, and with greatly varying installation structures. They occupy a large space and have low space utilization.

[0084] It is necessary to install pipelines, pipe joints, valves and other components on the vehicle chassis one by one, and then hang and install the scattered equipment one by one. Finally, the connecting pipes between the longitudinal pipelines and the equipment are installed one by one to meet the air demand of each equipment. It involves multiple processes and cannot be carried out simultaneously. The installation of components is scattered and complicated, resulting in low construction efficiency.

[0085] Rigid pipe connections are generally used to connect the air supply pipe to the equipment interface terminal. Due to the accumulation of installation errors, the terminal interfaces of the two cannot be connected normally or the air tightness is poor after connection. At this time, it is necessary to constantly adjust the position of the middle pipe interface or temporarily adjust the length and angle of the connecting pipe for matching. This matching process is time-consuming and labor-intensive, and the installation quality is not stable enough.

[0086] In the early stage, pipelines, valves and other components were installed in a scattered manner. When the equipment needed to be dismantled and taken off the vehicle for inspection and maintenance, they could not be directly removed due to obstruction by other equipment or local pipelines. Individual equipment or pipelines had to be removed first before the components could be removed for inspection, resulting in poor maintainability.

[0087] In response to these problems, the rail vehicle provided in the present application is analyzed and integrated through braking principles and mounting components to form a first-end brake box 1, a second-end brake box 2 and a longitudinal pipe row 3. The first-end brake box 1 and the second-end brake box 2 are flexibly connected to the longitudinal pipe row 3, and the braking, operation, display and air supply functions are realized through the brake box.

[0088] The first-end brake box 1 and the second-end brake box 2 adopt the side beam hanging form, which changes the traditional crossbeam hanging method and forms a new type of hanging structure 4. This structure does not need to set the body crossbeam, thereby reducing the weight of the body, while avoiding the scattered installation of equipment, making the equipment installation more compact, saving a lot of space, and improving the integrity and modularity.

[0089] The design of the middle longitudinal pipe row 3 realizes complete assembly and disassembly, avoiding the problem that the middle pipes need to be installed one by one, greatly simplifying the installation process and improving construction efficiency. In addition, the fluid control devices 9 such as the cut-off valve have been integrated into the equipment box, and the cut-off valve does not need to be separately set and installed in the middle pipe, further simplifying the system structure.

[0090] The equipment box and the middle longitudinal pipe row 3 are connected by a flexible hose, which effectively solves the matching problem caused by errors between the terminal gas circuit interfaces of the two, and improves the stability and reliability of the installation. At the same time, the installation and disassembly of the equipment box and the longitudinal pipe row 3 are independent of each other and do not interfere with each other, which solves the problem that the pipeline cannot be disassembled separately due to equipment obstruction, greatly improving the maintenance and repair. The pipelines under the vehicle are arranged in order according to functional requirements, and there is no crossing between the longitudinal pipelines, which further improves 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 lifting system provided in an embodiment of the present application in a rail vehicle.

[0092] In some embodiments, the rail vehicle also includes a first-end bogie 02, a second-end bogie 03 and under-vehicle 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, the under-vehicle electrical equipment 04 is longitudinally distributed between the first-end brake box 1 and the second-end brake box 2, and the under-vehicle electrical equipment 04 is located on the lower side of the longitudinal pipe row 3.

[0093] In this embodiment, the bogies, as an important part of the rail vehicle, are responsible for supporting the weight of the rail vehicle and guiding the rail vehicle to travel along the track. Their layout corresponds to the brake box, making the weight distribution of the rail vehicle more balanced, which helps to improve the stability and running performance of the rail vehicle. When working, 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.

[0094] The undercarriage electrical equipment 04 is longitudinally distributed between the first-end brake box 1 and the second-end brake box 2, and is located at the lower side of the longitudinal pipe row 3. This layout allows the electrical equipment and the brake system to cooperate with each other, facilitating the coordinated work of the electrical control and brake control of the rail vehicle. The undercarriage electrical equipment 04 is responsible for providing power supply, signal transmission and control functions for the rail vehicle. The longitudinal distribution of the electrical equipment and its placement at the lower side of the longitudinal pipe row 3 is conducive to optimizing the spatial layout of the rail vehicle and improving the integration and maintenance efficiency of the equipment.

[0095] In the specific implementation of the present application, the installation and layout of the equipment hoisting system are carefully designed to ensure its efficiency and reliability. First, the installation positions of the first-end brake box 1 and the second-end brake box 2 are optimized so that they can achieve the best weight distribution and function at both ends of the rail vehicle. This layout not only helps to improve the operating stability of the rail vehicle, but also reduces the vibration and noise generated by the rail vehicle during driving to a certain extent, thereby improving the riding experience of passengers.

[0096] During the installation process, the use of the supporting structure 4 has also been carefully considered. The design of the lifting lug 41 and the lining plate 42 not only ensures a firm connection between the brake box and the side beam 01, but also takes into account the convenience of installation and disassembly. By setting the process hole 011 on the side beam 01, the lifting lug 41 can be smoothly moved from the lower side of the side beam 01 to the upper side. This design greatly simplifies the installation steps and reduces the installation time and labor intensity. At the same time, the use of the lining plate 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 work of the first-end bogie 02 and the second-end bogie 03 and the brake box has also been fully considered. The layout of the bogie corresponds to the brake box, making the weight distribution of the rail vehicle more balanced, which helps to improve the stability and operating performance of the rail vehicle. When working, 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 can achieve precise braking and steering of the rail vehicle and improve the controllability 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 the design and implementation process to ensure their efficient, stable and reliable operation. By optimizing the installation layout, improving the structural strength and enhancing the coordinated control capability, this application provides strong technical support and guarantee for the operation of rail vehicles.
