Description

Technical Field

[0001] This invention relates to the field of urban rail transit emergency rescue technology, and in particular to a rapid rescue method for a rescue vehicle, a rescue mother vehicle, and a rail train. Background Technology

[0002] With the widespread adoption of urban rail transit systems such as subways and light rail in major cities, subway and light rail travel has become the preferred mode of transportation for ordinary people, leading to a continuous increase in the length and coverage of subway and light rail lines. Consequently, the operating time and frequency of light rail trains are constantly breaking records, and consequently, the failure rate of light rail trains is also constantly increasing.

[0003] The existing rescue method is as follows: when a train derails in a subway tunnel, rescuers travel by vehicle to the nearest subway station entrance. Once at the station entrance, the rescuers carry the tools by hand to the accident site. After the rescue is completed, the tools are carried back to the rescue vehicle by hand. The process of taking, carrying, and placing the rescue tools requires 12 rescuers and takes more than 45 minutes.

[0004] Existing rescue methods are labor-intensive, with a large number of rescue personnel being used to transport supplies, wasting valuable rescue time, prolonging the time required to restore rail transit operations, and reducing economic losses. Summary of the Invention

[0005] In view of this, it is necessary to provide a rapid rescue method for railcars to solve the problem of time-consuming and labor-intensive existing rescue methods.

[0006] The present invention provides a rescue vehicle, including a vehicle body, with rail wheel sets at the front and rear ends of the vehicle body to assist the movement of the rails, and a locking assembly, the locking assembly including a plurality of retractable limiting posts, the limiting posts being arranged perpendicular to the vehicle body and inserted into the vehicle body, the plurality of protruding limiting posts enclosing a limiting space for restricting the horizontal movement of the toolbox.

[0007] In some embodiments, the vehicle body is provided with straps, one end of which is connected to one side of the vehicle body, and the other end of which is detachably connected across the vehicle body to the other side of the vehicle body for securing a toolbox from the top.

[0010] On one hand, the present invention provides a rescue mother vehicle, including a carriage, with shelves on both sides of the interior of the carriage, the shelves being spaced apart, the distance between the shelves forming a carrying space for accommodating a rescue daughter vehicle, the height of the shelves being the same as the height of the vehicle body; the toolbox is movable between the shelves and the vehicle body.

[0011] In some embodiments, a crew compartment for accommodating maintenance personnel is provided between the carriage and the locomotive, and the crew compartment can accommodate 4-6 rescue personnel.

[0012] On the one hand, the present invention provides a rapid rescue method for railcars, which includes the following steps:

[0013] Derailment accident feedback: After a train derails and comes to an emergency stop, the vehicle automatically sends an alarm to the emergency rescue system, providing real-time information about the derailed train.

[0014] Emergency response of rescue vehicles: The emergency rescue system sends instructions to the maintenance center, and the mother rescue vehicle carries multiple rescue vehicles and rescue personnel to the station entrance closest to the train. The rescue vehicles move to the platform and enter the track area.

[0015] Rescue vehicle wheel conversion: The rescue vehicle is converted from ordinary pneumatic tires to rubber-coated steel wheels that fit the track, allowing the rescue vehicle to travel quickly along the track;

[0016] Categorized rescue: Multiple rescue vehicles are each equipped with a rerailing device to handle different degrees of derailment, and work together to deal with train derailment accidents.

[0017] In some embodiments, during the derailment incident feedback process, the vehicle's camera license plate system automatically takes pictures of the vehicle and uploads them to the emergency rescue system to determine the degree of train derailment.

[0018] In some embodiments, the emergency rescue system can determine the degree of train derailment based on real-time feedback from the accident site, and thus allocate different rescue vehicles.

[0019] In some embodiments, the emergency rescue system can determine the nearest station to the derailment accident site based on the location of the derailment and plan the optimal route for the rescue mother vehicle based on real-time traffic conditions. The emergency rescue system can also communicate with the public security traffic management system to control the operation of traffic lights, ensuring unimpeded access for the rescue mother vehicle.

[0029] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] This application discloses a rapid rescue method involving a rescue subcar, a rescue mother car, and a rail train, which relates to the field of urban rail transit emergency rescue technology. By utilizing the cooperative rescue subcar 100 and rescue mother car 200, the rescue mother car 200 carries the rescue subcar 100. The rescue subcar 100 can travel rapidly on the rail using the rail wheel set 120, which can shorten the rescue time and improve the rescue efficiency.

[0031] Please see Figure 1 A rescue vehicle 100 includes a vehicle body 110, with rail wheel sets 120 at both the front and rear ends of the vehicle body 110. The rail wheel sets 120 can assist the vehicle body 110 in moving quickly on the rails. The rescue vehicle 100 also includes a locking assembly 130, which includes multiple retractable limiting posts 131. The limiting posts 131 are perpendicular to the vehicle body 110 and inserted into the vehicle body 110. The multiple protruding limiting posts 131 enclose a limiting space, which hinders the movement of a toolbox 300 from multiple directions, restricts the movement of the toolbox 300 on the vehicle body 110, and prevents the toolbox 300 from excessively vibrating and tipping over when the vehicle body 110 is moving.

[0032] In some embodiments, please continue reading Figure 1 The vehicle body 110 is provided with a strap 140. One end of the strap 140 is connected to one side of the vehicle body 110, and the other end of the strap 140 is detachably connected across the vehicle body 110 to the other side of the vehicle body 110. When the toolbox 300 is surrounded by the limiting post 131 on the vehicle body 110, the strap 140 can restrain the top of the toolbox 300 to prevent the toolbox 300 from coming out of the top of the limiting space.

[0033] In some embodiments, the vehicle body 110 is equipped with a drive motor and a remote sensing controller. The remote sensing controller is electrically connected to the drive motor and is connected to a remote controller via electromagnetic waves. Rescue personnel on the ground can wirelessly control the movement and steering of the vehicle body 110 via the remote controller.

[0034] It should be noted that the rescue vehicle 100 is fully electric and automatically driven, with a lithium battery and a drive motor inside. The drive motor is used to drive the movement and steering of the rescue vehicle 100, making it easier to operate. The rescue vehicle 100 abandons the internal combustion engine and will not emit various pollutants in the relatively sealed subway tunnel, thus not interfering with the rescue operations of rescue personnel.

[0035] In some embodiments, the track wheel assembly 120 is connected to the vehicle body 110 via a bracket, and the track wheel assembly 120 can move or rotate vertically relative to the vehicle body 110.

[0036] In the specific implementation process, the track wheel set 120 includes two rubber-coated steel wheels arranged opposite each other. The bracket is T-shaped and includes a first connecting rod and a second connecting rod that are perpendicular to each other. One end of the first connecting rod is fixedly connected to the middle of the second connecting rod. The two rubber-coated steel wheels are installed at both ends of the second connecting rod and are rotatably connected to the second connecting rod.

[0037] In some embodiments, the other end of the first link is hinged to the vehicle body 110, and the track wheel assembly 120 can be driven to cooperate with the rail by setting a cylinder or hydraulic cylinder between the second link and the vehicle body 110.

[0038] In other embodiments, the first connecting rod is vertically arranged, and the two ends of the cylinder or hydraulic cylinder are respectively connected to the first connecting rod and the bottom of the vehicle body 110. The cylinder or hydraulic cylinder can drive the track wheel assembly 120 to move up and down, thereby causing the rubber-coated steel wheel to cooperate with the rail.

[0039] Rubber-coated steel wheels can be used with steel rails to guide the movement of the rescue trolley and prevent it from detaching from the rails, thus avoiding unnecessary damage.

[0040] The rescue trolley 100 is converted from ordinary pneumatic tires to rubber-coated steel wheels that work with steel rails. With the assistance of these rubber-coated steel wheels, the rescue trolley 100 can move quickly along the rails at a uniform speed and with stable operation. A hinged bracket is installed between the rubber-coated steel wheels and the rescue trolley 100. Both ends of the bracket are connected to the rubber-coated steel wheels and the rescue trolley 100, respectively. By driving the bracket to rotate relative to the rescue trolley 100, the distance between the rubber-coated steel wheels and the ground is changed, controlling the contact and disengagement of the rubber-coated steel wheels with the steel rails, ultimately achieving the switching between pneumatic tires and rubber-coated steel wheels relative to the steel rails.

[0041] A rescue mother vehicle includes a carriage with shelves 210 on both sides of the interior. The shelves 210 are spaced apart, forming a carrying space for a rescue trolley 100. The spacing between the shelves 210 is consistent with the width of the rescue trolley. The shelves 210 can limit the movement of the rescue trolley within the carrying space. The height of the shelves 210 is the same as the height of the vehicle body 110, allowing a toolbox 300 to move on a flat surface without height difference, thus facilitating the transfer of the toolbox 300 between the shelves 210 and the vehicle body 110.

[0042] In some embodiments, a crew compartment 220 for accommodating maintenance personnel is provided between the carriages and the locomotive of the car body 110. The crew compartment 220 can accommodate 4-6 rescue personnel. The crew compartment 220 is equipped with seats and a communication system. Rescue personnel can use the communication system to contact the train to be rescued. The train to be rescued can provide the rescue personnel with real-time information about the accident scene and rescue plans, assisting the rescue personnel in subsequent rescue efforts and saving time in emergency rescue.

[0043] Meanwhile, a navigation system is installed in the driver's cab, which can guide the driver and plan the shortest route between the rescue mother vehicle 200 and the platform, reducing the time spent on the road.

[0044] Please see Figure 3 This embodiment of a rapid rescue method for railcars includes the following steps:

[0045] Derailment accident feedback: After a train derails due to various accidents, it will detach from the rails and stop running immediately. The train's various sensors will send alarms to the rail transit central control system and report the partial derailment. The rail transit central control system will then feed back the relevant information to the emergency rescue system.

[0046] At the same time, the train's onboard monitoring and imaging equipment will capture images of the train's position and condition, and upload the photos and videos to the emergency rescue system. The emergency rescue system will then assess the extent of the train's derailment and develop a contingency plan.

[0047] Emergency Response by Rescue Vehicles: Upon receiving relevant information, the emergency rescue system analyzes the distances between the accident site and multiple nearby stations to determine the closest station. Based on real-time traffic conditions, the system plans the optimal route for the main rescue vehicle (200). The system can also communicate with the public security traffic management system to control traffic lights, ensuring unimpeded access for the main rescue vehicle (200). Through these steps, the time it takes for the main rescue vehicle (200) to reach the target station can be shortened.

[0048] Wheelset conversion for Rescue Trolley 100: Rescue Trolley 100 is converted from ordinary pneumatic tires to rubber-coated steel wheels that fit the track. With the assistance of the rubber-coated steel wheels, Rescue Trolley 100 can move quickly along the track at a uniform speed and run stably.

[0049] Categorized Rescue: Multiple rescue vehicles 100 are each equipped with rerailing devices for different degrees of derailment, working together to handle train derailment accidents of varying severity. The emergency rescue system can determine the severity of the derailment accident based on real-time feedback from the accident site, thus equipping the main rescue vehicle 200 with the appropriate rescue vehicles 100. Each rescue vehicle 100 carries the corresponding tools to handle the specific accident, enabling more precise and targeted rescue operations.

[0050] As one implementation method, when a minor train derailment occurs, with the train's position approximately 20cm off the track, the following steps are required to re-track the train:

[0051]

[0052]

[0053] As one implementation method, when a moderate train derailment occurs, and the train's position deviates from the track by more than 20cm, the following steps are required to re-track the train:

[0054]

[0055]

[0056]

[0057] As one implementation method, when a train derails severely and overturns, the following steps are required to re-track the train:

[0058]

[0059]
