Description

Technical Field

[0001] This utility model relates to the technical field of urban rail transit rescue equipment, specifically to a low-floor subway double-track equipment with a U-shaped beam structure, which is particularly suitable for lifting and lateral repositioning rescue operations after a low-floor subway derailment where the lifting apex is located on both sides of the car body and the distance between the car body and the U-beam is small. Background Technology

[0002] Low-floor metro systems are widely used in urban rail transit suburban lines and branch lines due to their convenient travel and small turning radius. Many of these lines are laid on U-shaped beam track structures, which are characterized by a small internal working space and a very close distance between the track sidewalls and the car body. At the same time, the car body structure design of low-floor metro systems means that the lifting apex is only distributed on both sides of the car body and the apex position is low, which has become a unique feature of this type of vehicle for derailment rescue.

[0003] Currently, existing hydraulic double-tracking equipment for rail vehicles is unsuitable for this specific scenario, mainly due to the following issues: The cylinders and lateral movement mechanisms of existing double-tracking equipment are large and tall, making them unsuitable for deployment within the narrow gap between the car body and the U-shaped beam. Furthermore, it is difficult to accurately align the lifting apexes on both sides of the car body. Moreover, existing double-tracking equipment cannot be deployed and operated as a whole within the narrow space of the U-shaped beam. In particular, the operating procedures of existing double-tracking equipment are not designed for "lifting the sides of the car body," easily leading to uneven force during lifting. After lateral movement, auxiliary components cannot be quickly removed within the narrow space, affecting double-tracking efficiency. Additionally, the connection methods of most existing components are complex, requiring specialized tools, making disassembly and assembly difficult within the confined working space of the U-shaped beam, failing to meet the rapid response requirements for emergency rescue. There is a lack of step-by-step operating procedures adapted to this scenario for rescue operations involving low-floor metro cars in the narrow space of U-shaped beam track structures, making it difficult to meet the needs for efficient, safe, and convenient rescue after a derailment of a low-floor metro car on a U-shaped beam track.

[0004] Therefore, there is an urgent need to develop a low-floor subway double-track system with a U-shaped beam structure to solve the above problems. Utility Model Content

[0005] This utility model is a double-track equipment for low-floor subway rescue on U-shaped beam structure tracks. By designing a lifting module and a lateral movement module, this utility model is modularly applied to the rescue process of subway cars in narrow spaces and with low floors, effectively solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-floor subway double-track device on a U-shaped beam structure track, comprising a hydraulic pump station, a lifting module, and a lateral movement module. The lifting module includes multi-stage lifting cylinders and cylinder supports, with the cylinder supports fixedly mounted on the top of each multi-stage lifting cylinder.

A high-pressure hose is fixedly connected to one side of the hydraulic pump station, and the hydraulic pump station is connected to the multi-stage lifting cylinders and the lateral movement mechanism via the high-pressure hose. Four sets of the lifting modules and four sets of the lateral movement modules are respectively installed above the U-shaped beam structure track for lifting and lateral movement of the subway car body.

[0010] Preferably, the lateral movement mechanism includes a lateral movement panel, a PTFE sliding plate, a lateral movement cylinder, a bearing platform, a quick-release stroke limit module, and a self-centering clamping seat. The lateral movement cylinder is fixedly connected inside the bearing platform, and the lateral movement panel is clamped and fixed above the lateral movement cylinder. The PTFE sliding plate is fixedly connected above the bearing platform. The extension and retraction of the lateral movement cylinder drives the lateral movement panel to reciprocate on the PTFE sliding plate.

[0011] Preferably, the overall length of the transverse mechanism is less than 500mm, the overall height of the transverse mechanism is less than 95mm, and the transverse stroke of the transverse mechanism is 0mm-200mm.

[0012] Preferably, the bearing platform is provided with limiting transverse grooves on both sides, and a scale is provided on one side of the limiting transverse groove. The quick-release travel limiting module is fixed to the bearing platform by snapping together with the limiting transverse groove to fix and limit the transverse movement panel.

[0013] Preferably, the quick-release travel limit module includes a quick-release bolt, a limit frame, a limit slider, a limit buffer pad, and a pointer. The limit frame is fixedly connected to the top of the limit frame, the limit slider is threadedly connected to the limit frame, the quick-release bolt is movably connected to the limit slider, and a pointer is fixedly connected to the bottom of the limit frame. The pointer corresponds to the scale position of the limit groove to accurately control the transverse travel.

[0014] Preferably, a self-centering clamping seat is fixedly connected above the transverse panel. The multiple self-centering clamping seats clamp and fix the support pad. The self-centering clamping seat includes an arc-shaped clamping seat, a rubber buffer pad, a positioning seat, a spring, a shaft clip, and a seat handle. The positioning seat is bolted to the transverse panel. The seat handle passes through the positioning seat and is fixedly connected to the arc-shaped clamping seat. The spring is sleeved on the outside of the seat handle. The spring is located between the positioning seat and the arc-shaped clamping seat.

[0015] Preferably, the hydraulic pump station integrates a wireless remote control module, a multi-parameter real-time monitoring module, and a hydraulic self-locking protection module. The wireless remote control module is remotely controlled using a matching wireless remote controller.

[0016] This utility model provides a double-track equipment for low-floor subway rescue on U-beam structure tracks, which has the following advantages compared with the existing technology:

[0017] This utility model is specifically designed for the narrow space of U-shaped beam track and the lifting apexes on both sides of the low-floor subway car body. The multi-stage lifting cylinders and lateral movement mechanism are all ultra-thin structures, which can be precisely deployed within the narrow gap between the car body and the U-shaped beam. The four cylinders are arranged in pairs to correspond to the lifting apexes on both sides of the car body, ensuring uniform lifting force. It is fully adapted to the structural requirements of rescue scenarios with narrow gaps in the car body. At the same time, the application of quick-release stroke limit module and self-centering clamping seat makes the operation more precise and the limit more stable during the rescue process, effectively improving the overall safety of the device.

[0018] The components of this utility model adopt a lightweight and ultra-thin design, with a single component weighing ≤15kg. They can be carried by a single person. The components are connected by a quick-release structure and quick-change hydraulic joints, requiring no special tools throughout the process. They can be quickly deployed and disassembled in the narrow space of the U-shaped beam, meeting the rapid response needs of emergency rescue and flexibly adapting to various narrow spacing situations.

[0019] This invention solves the problems of integrated re-line equipment being unable to operate in narrow spaces and auxiliary parts being difficult to remove by using the operation steps of "lifting → deploying → resetting and removing → lowering" in narrow spaces. The operation steps of this invention are simple and easy for operators to learn.

[0020] This utility model's hydraulic pump station integrates a wireless remote control module, eliminating the need for close-range operation in narrow spaces, thus avoiding safety hazards such as bumps and squeezing during operation, and improving operational safety and efficiency.

[0038] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model. The technical solutions of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0039] Please see Figures 1-7 This utility model provides a technical solution:

[0040] A hydraulic double-tracking device for low-floor subways with a U-shaped beam structure includes a hydraulic pump station 1, a lifting module, and a lateral movement module. The lifting module includes a multi-stage lifting cylinder 2 and a cylinder support 3. The cylinder support 3 is fixedly mounted on the top of the multi-stage lifting cylinder 2. The lateral movement module includes a lateral movement mechanism 4 and a support pad 5. The support pad 5 is clamped and fixedly mounted on the top of the lateral movement mechanism 4. A high-pressure hose 6 is fixedly connected to one side of the hydraulic pump station 1. The hydraulic pump station 1 is connected to the multi-stage lifting cylinder 2 and the lateral movement mechanism 4 through the high-pressure hose 6. All components are lightweight, ultra-thin, and modular, adaptable to the narrow space operation requirements of lifting the inner apex 801 on both sides of the low-floor subway car body 8 and the distance between the car body and the U-shaped beam structure track 7 ≤ 300mm. Each component weighs ≤ 15kg, can be manually handled by a single person, and can be quickly disassembled and connected without special tools.

[0041] In some embodiments, the multi-stage lifting cylinder 2 is an ultra-thin double-acting hydraulic cylinder with an overall height of ≤170mm and a rated single-cylinder load of ≥7.5t. Each cylinder is equipped with a hydraulic lock 201 with unloading function. After the four cylinders are positioned and installed with cylinder top supports 3 through grooves 202, they are precisely aligned with the inner lifting apex 801 on both sides of the low-floor subway car body 8. Synchronous lifting can be achieved through the hydraulic pump station 1, lifting the car body until the wheels are separated from the rails 9 by no less than 30mm, which meets the deployment space requirements of the subsequent transverse movement mechanism 4.

[0042] In some embodiments, the cylinder top support 3 has an arc-shaped structure with anti-slip texture 301 on the surface. The lower end of the cylinder top support 3 has a boss 302, which is connected to the lifting end groove 202 of the multi-stage lifting cylinder 2. It can be quickly disassembled and assembled without slipping during lifting, thus avoiding damage to the vehicle body.

[0043] In some embodiments, the four transverse movement mechanisms 4 are miniaturized ultra-thin horizontal transverse movement structures with an overall height of ≤95mm. They include a transverse movement panel 401, a PTFE sliding plate 402, a transverse movement cylinder 403, a support platform 404, a quick-release stroke limit module 405, and a self-centering clamping seat 406. The transverse movement stroke of the transverse movement cylinder 403 is 0mm-200mm, and the thrust is 4.5t. After the support pad 5 is installed on the support platform 404, it is adapted to the outer apex 802 of the lifting on both sides of the vehicle body to ensure that the vehicle body is subjected to uniform force during the transverse movement. The quick-release travel limit module 405 includes a quick-release bolt 4051, a limit frame 4052, a limit slider 4053, a limit buffer pad 4054, and a pointer 4055. The limit frame 4052 is installed in the limit mounting hole of the bearing platform 404 by the quick-release bolt. The pointer 4055 is set on the limit frame 4052. The position of the limit frame 4052 can be quickly adjusted according to the wheel offset distance to achieve precise mechanical limit of the lateral travel. In conjunction with the electro-hydraulic control of the hydraulic pump station 1, dual travel protection is achieved. The self-centering clamping seat 406 includes an arc-shaped clamping seat 4061, a rubber buffer pad 4062, a positioning seat 4063, a spring 4064, a shaft clip 4065, and a seat handle 4066. The seat handle passes through the positioning seat 4063 and is fixedly connected to the arc-shaped clamping seat 4061. The spring 4064 is sleeved on the outside of the seat handle 4066 and is located between the positioning seat 4063 and the arc-shaped clamping seat 4061. The spring 4064 is kept in a compressed state. The shaft clip 4065 is sleeved on the outer part of the seat handle 4066 of the positioning seat 4063 and limits the seat handle 4066 by snapping it in place. The rubber buffer pad 4062 is fixedly connected to the inner side of the arc-shaped clamping seat 4061 to protect the support pad 5 during the clamping process. After assembly, it is installed on the transverse sliding panel 401 by bolts to realize the self-centering clamping function of the support pad 5. The rubber buffer pad 4062 is installed on the arc-shaped clamping seat 4061 to better protect the support pad 5.

[0044] In some embodiments, the support pad 5 is made of lightweight aluminum alloy, which reduces its weight while ensuring strength. Each support pad 5 has an insertion hole at the top for stacking height and a block at the bottom for positioning. After the support pad 5 is installed on the transverse mechanism 4, it can realize the horizontal leveling and stable support of the transverse mechanism 4.

[0045] In some embodiments, the hydraulic pump station 1 is a miniaturized, mobile integrated pump station with an overall weight of ≤40kg. It is equipped with casters at the bottom for easy on-site movement outside the U-shaped beam structure track 7. The pump station integrates a wireless remote control module 101, a multi-parameter real-time monitoring module, and a hydraulic self-locking protection module. The matching 2.4G wireless remote controller 102 has a remote control distance of ≥50m, allowing operators to remotely control the cylinder lifting and lateral movement mechanism 4. The wireless remote controller 102 is equipped with an LCD screen that can display the working pressure, lifting height, and lateral movement stroke in real time. When the working pressure, oil temperature, or liquid level exceeds the set values, the hydraulic self-locking protection module automatically locks the cylinder to ensure operational safety.

[0046] This utility model relates to the derailment rescue operation procedure for a low-floor subway car body 8 on a U-shaped beam structure track 7. The specific operation steps are as follows:

[0047] S1. First, the operators precisely deploy the multi-stage lifting cylinders 2 below the inner tops 801 on both sides of the low-floor subway car body 8, and position and install the cylinder top support 3 with the boss 302 in the groove 202 of the multi-stage lifting cylinder 2; place the hydraulic pump station 1 in the safe area outside the U-shaped beam structure track 7, and hydraulically connect the hydraulic pump station 1 to the multi-stage lifting cylinder 2 through the high-pressure hose 6, and check the sealing of the connection.

[0048] S2. The operator retreats to the outside of the accident vehicle body and starts the hydraulic pump station 1 through the wireless remote control 102. The multi-stage lifting cylinder 2 is controlled to lift synchronously, so that the cylinder support 3 is in close contact with the inner lifting apex 801 on both sides of the subway car body 8. The lifting continues until the wheels of the car body are separated from the rails 9 by at least 30mm, and then the lifting stops. The hydraulic lock 201 lifts and locks itself to keep the car body in the lifting state, reserving operating space for the subsequent deployment of the transverse movement mechanism 4.

[0049] S3. In the reserved space after the car body is lifted, four sets of transverse movement mechanisms 4 are deployed below the outer lifting apex 802 on both sides of the low-floor subway car body 8. The support pads 5 are installed on the transverse movement panel 401. After the support pads 5 are stacked, they fit with the outer lifting apex 802 on both sides of the car body. The position of the limiting frame 4052 is quickly adjusted according to the wheel offset distance. The hydraulic pump station 1 and the transverse movement mechanism 4 are hydraulically connected through the high-pressure hose 6.

[0050] S4. The lateral movement cylinder 403 of the lateral movement mechanism 4 is controlled by the wireless remote controller 102 to move the car body horizontally until the wheels of the subway car body 8 are aligned with the rails 9 to complete the car body reset. After the lateral movement is completed, the lateral movement mechanism 4 is kept in a self-locking state.

[0051] S5. Reposition the multi-stage lifting cylinder 2 and cylinder top support 3 below the inner lifting top 801 on both sides of the low-floor subway car body 8. Control the multi-stage lifting cylinder 2 to lift the car body again using the wireless remote control 102, leaving space for the removal of the lateral movement mechanism 4 and support pad 5. Then, manually remove the lateral movement mechanism 4 from under the car body in the narrow space.

[0052] S6. After confirming that the lateral movement mechanism 4 has been completely withdrawn, the multi-stage lifting cylinder 2 is slowly and synchronously lowered by the wireless remote controller 102, so that the wheels of the vehicle body fall on the rail 9, completing the entire re-tracking operation; finally, the hydraulic connection between the multi-stage lifting cylinder 2 and the hydraulic pump station 1 is disconnected, the cylinder top support 3 and the multi-stage lifting cylinder 2 are removed in sequence, all equipment is manually moved to the rescue vehicle, the on-site working environment is cleaned up, and the on-site rescue closing procedures are completed.

[0053] Example 1:

[0054] In this embodiment, the low-floor subway car 8 derailed in the section of the U-shaped beam structure track 7. The wheels shifted laterally without serious tilting. The distance between the subway car 8 and the side wall of the U-shaped beam was approximately 280mm. Rescue personnel carried out the rescue operation. First, they manually moved four ultra-thin multi-stage lifting cylinders 2 with an overall height of 165mm and the arc-shaped cylinder support 3 to the inner apex 801 on both sides of the car body. After connecting the hydraulic lines, the operator remotely controlled the car body from a safe area 50 meters away, lifting it synchronously by 40mm. The lifting process was smooth, and the display screen of the wireless remote controller 102 provided real-time feedback on the uniform pressure of each cylinder.

[0055] Four lateral movement mechanisms 4 are placed within the jacking space. Aluminum alloy support pads 5 are placed into the fixing holes of the lateral movement panel and automatically clamped by self-centering clamping brackets 406. Based on the measured offset, the travel limit slider 4053 is set to the corresponding scale position via quick-release bolts 4051. The lateral movement cylinder 403 is remotely activated, and the vehicle body moves smoothly laterally. When the lateral movement panel 401 reaches the quick-release travel limit module 405, the lateral movement automatically stops. The mechanical limit and hydraulic control provide dual protection, ensuring precise wheel return.

[0056] The process involves a second lifting, removal of the lateral movement mechanism 4 and support pad 5, and finally lowering of the vehicle body. The entire core operation is completed within 30 minutes. All components are manually disassembled using a quick-release structure, requiring no electric or pneumatic tools.

[0057] Example 2:

[0058] This embodiment focuses on rapid deployment in extremely confined or time-sensitive scenarios. In this embodiment, the support platform 404 of the traverse mechanism 4 is made of high-strength carbon fiber composite material, making it lighter than the titanium alloy solution. All quick-release handles are equipped with anti-slip textures 301 and fluorescent markings for easy operation while wearing gloves and identification in low light conditions.

[0059] The lifting operation is controlled remotely by one person. The lifting module and the lateral movement module are quickly deployed and removed by two groups of people before and after the lifting. Due to the lighter weight of the components and faster connection, the lateral movement reset and removal process consumes less physical strength and is faster.

[0060] Example 3:

[0061] During the deployment of the multi-stage lifting cylinders 2 and the initial lifting operation, the operator uses the total pressure and oil temperature displayed on the wireless remote control 102 screen to check the stress on four locations of the vehicle body. When the vehicle body tilts slightly due to uneven road surfaces, it is possible to observe whether there are reasonable differences in the pressure of the multiple cylinders in the hydraulic pump station 1.

[0062] During the lateral repositioning process, the working pressure of the lateral cylinder 403 briefly increases due to slightly greater resistance in the curve. When the pressure value approaches the system's preset safety threshold, the remote control issues an audible and visual warning. The operator can then pause the operation for adjustments. Simultaneously, the multi-parameter monitoring module integrates data from a simple tilt sensor. During the lifting and lateral movement, the screen displays the approximate tilt angle change of the vehicle body, assisting the operator in judging whether the repositioning process is smooth. If the tilt angle exceeds the limit, the hydraulic self-locking protection module will intervene.

[0063] The wireless module of hydraulic pump station 1 can transmit key operating parameters (such as pressure and alarm events) to the rear command terminal in real time, enabling visual monitoring and recording of the rescue process. When a derailment accident occurs on a curve and the car body is slightly tilted, more precise force and attitude monitoring is required during the rescue to prevent secondary skidding.

[0064] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments. For those skilled in the art to which the present invention pertains, several simple deductions or substitutions can be made without departing from the present invention, and all such deductions or substitutions should be considered as falling within the scope of patent protection determined by the submitted claims.
