Description

Technical Field

[0001] The invention belongs to the technical field of railway vehicle design and relates to a railway tunnel fire rescue vehicle. Background Art

[0002] Currently, my country's main railway freight cars have a maximum operating speed of 120 km / h and can carry up to 70 tons per train. my country's railway construction involves numerous tunnels along mountainous lines, with the length of individual tunnels constantly increasing, often reaching tens of kilometers. Subway construction also primarily involves tunnels.

[0003] Subway and railway tunnels operate in unique environments, with limited escape routes and numerous potential risk factors. Tunnels are typically long, presenting safety hazards such as difficult evacuation and rescue, long escape distances, and short escape times. Once a fire occurs, the heat and harmful smoke generated by the combustion are trapped in a confined space and difficult to dissipate, easily creating a high-temperature, smoky environment that can cause significant loss of life and property. Existing road fire trucks are unable to operate normally on railways. Dual-purpose road fire trucks typically operate at speeds of around 40 km / h on railway tracks, resulting in low track speeds and a gross vehicle weight generally exceeding 49 tons, with a load capacity far less than that of railway freight cars. Some dual-purpose road fire trucks have deficiencies in body size, track system balancing technology, and braking technology. These vehicles experience problems such as inability to brake after entering a tunnel and inability to open the cab door, making them unsuitable for rescue operations within railway tunnels. Therefore, it is necessary to develop a railway tunnel fire rescue vehicle that can meet the needs of firefighting and other rescue operations within railway tunnels. Summary of the Invention

DETAILED DESCRIPTION

[0038] The present invention is further described below in conjunction with specific embodiments. The specific embodiments are further explanations of the principles of the present invention and do not limit the present invention in any way. Technologies that are the same or similar to the present invention do not exceed the scope of protection of the present invention.

[0039] Combined with the attached drawings.

[0040] The railway tunnel fire rescue vehicle in this embodiment uses a railway flat car with a running speed of 120km / h. The flat car is as long as possible to improve the carrying capacity of rescue equipment and personnel. Figure 7 As shown, four container locking devices are fixed on both sides of the car body just above the bogie of the railway flat car, and four pad devices are fixed on both ends of the car body.

[0041] A carriage is made of plates, profiles and flame-retardant heat-insulating materials. The carriage comprises a base frame, a higher first side wall, a lower second side wall, an end wall, a partition wall, a double-end door and a flat roof.

[0042] The underframe is a frame structure with a full-length floor on the top surface. Four first ladders are fixed on both sides of the underframe. A rolling door with a wider door opening width L2 and an inward-opening side door are set on the first side wall. A second ladder made of a round tube is fixed on the outside of the second side wall. The first support of the mounting bracket is fixed on the upper end of the inner side of the second side wall. The underframe, first side wall, end wall and end door of the carriage form a box-shaped structure.

[0043] There is a partition wall with a passage door in the box, which divides the internal space of the box into a first cabin and a second cabin. The bottom, top and sides of the second cabin, as well as the side doors and passage doors are lined with flame-retardant insulation materials. When the side doors and passage doors are closed, the second cabin forms an enclosed space, providing protection for the personnel in the second cabin to prevent them from being burned by high temperatures at the scene of accidents such as fires. A window is set in the middle of the end wall to observe the situation outside the vehicle. A third ladder made of circular tubes is fixed on the outside of the end wall and the top cover. The lower part of the end wall is recessed toward the inside of the second cabin, forming a rectangular cavity with the chassis floor and the two first side walls, with the opening facing the front end of the car.

[0044] A water storage system is made of plates and pipes. The front end height h3 of the water storage system's container box is less than its rear end height h2 (i.e., h3 < h2), forming a stepped shape with a low front and a high rear. Space is reserved for installing a smoke exhaust fan above the front end of the water storage system, and h2 is slightly less than the height h1 from the top of the rectangular cavity to the floor of the chassis (i.e., h2 < h1). The water storage system is placed on the chassis at the front end of the car, and the rear end of the water storage system is stuffed into the rectangular cavity to form a semi-embedded structure, making full use of the space on the car, and then the water storage device is consolidated.

[0045] A bracket is made of plates and profiles, with bolt holes set at both ends. Bolts and other fasteners are used to fix the bracket to the first support on the inner side of the two second side walls, and ensure that the height h4 of the bottom of the bracket from the chassis floor is slightly greater than h3 (i.e. h3 < h4) to avoid interference between the bracket and the water storage device. A large hydraulically driven smoke exhaust fan that can rotate left and right is fixed in the middle of the top of the bracket. The air outlet of the smoke exhaust fan is located at the front end of the car, which can flexibly blow away the smoke and dust at the front end of the car and make full use of the space above the water storage device. A temperature sensor, a smoke concentration sensor and a gas composition sensor are installed on the first side of the bracket to respectively detect the ambient temperature, smoke concentration and concentration of dangerous gases such as CO. A pan-tilt infrared camera that can rotate in the vertical and horizontal planes is installed in the middle of the first side of the bracket to effectively record images even in dark environments.

[0046] The air supply device, storage rack, power control cabinet, fire pump, generator, and hydraulic station are sequentially consolidated between the partition wall and the end door in the first cabin. The air supply device is close to the partition wall. Several high-pressure gas cylinders are integrated in the air supply device, which can carry a large amount of compressed air. In a thick smoke environment, the compressed air is reduced in pressure by a pressure reducing valve and introduced into the second cabin through a release pipe to meet the long-term breathing needs of the personnel in the second cabin; the storage rack is arranged between the two rolling doors of the carriage to store on-board equipment, shortening the distance for taking and placing equipment and increasing the rescue speed. The power control cabinet is close to the first side wall of the carriage, and transforms and rectifies the electricity generated by the generator and distributes it to electrical equipment such as fire pumps, hydraulic stations, and lighting. The fire pump, generator, and hydraulic station are arranged close to the end door to leave a walking passage in the middle of the first cabin; a display is consolidated on the inner wall of the partition wall in the second cabin, which is connected to sensors and cameras through a wired network to dynamically display environmental safety information such as the outside temperature, gas composition, and images collected by sensors and cameras.

[0047] There are several side lights on the upper part of the first side wall of the carriage, and 4 front lights on the front end of the second side wall, which provide lighting in dim environments such as tunnels to ensure the illumination of the rescue environment.

[0048] There are two sets of sprinkler devices on the car roof, which include a second support, a main pipe, a first branch pipe, a second branch pipe, a nozzle and a water supply hose. The main pipe is set close to the edge of the car roof and parallel to the longitudinal center line of the car. Several second supports are fixed to the bottom of each main pipe. The second support is fixed to the car roof by screws, etc. The water supply hose is arranged on the inside of the main pipe, one end is connected to the main pipe, and the other end penetrates the top cover and is connected to the third branch pipe and the fourth branch pipe of the fire pump respectively. Several first branch pipes are arranged on the outside of the main pipe, and their first axes are perpendicular to the longitudinal center line of the car. The ends of the first branch pipes are horizontally connected to the nozzles to spray conical water mist to the sides of the car. Several L-shaped second branch pipes are arranged on the main pipe The two ends are located on the inner side of the main pipe, and the second axis of the second branch pipe is tilted to point to the front end or the rear end of the car. The ends of the second branch pipes are connected to nozzles, which spray conical water mist upward at an angle toward the front end or the rear end of the car. Under the limited tunnel height, the spraying distance and spraying height of the water mist are taken into account. Pipes and stop valves are used to connect the water storage device, fire pump, and sprinkler device to form a water supply passage with controllable on and off. The clean water in the water storage device is pressurized by the fire pump and transported to the sprinkler device. The pressurized water flows through several nozzles and is atomized to form a fine water mist surrounding the rescue vehicle, which physically cools the rescue vehicle to prevent the high temperature at the accident scene from damaging the vehicle and the people on board, and washes the smoke and dust, significantly reducing the smoke and dust concentration.

[0049] One end of the fifth branch pipe is connected to the fire pump outlet pipe, and the other end is connected to the fire water pipe. The outlets at both ends of the fire water pipe are located on both sides of the carriage, and are equipped with standard fire interfaces that match the fire hoses. The fire hoses and fire guns are connected through the fire interfaces to perform fire extinguishing operations.

[0050] After completing the installation of the above-mentioned devices, the carriage is hoisted above the flat car, and the bottom hole of the container bottom corner piece is aligned with the container locking device on the railway flat car and then dropped. The carriage is supported, restrained and fixed on the railway flat car. The container locking device mainly bears the weight of the carriage and transfers the load to the bogie in the shortest path. The pad device supports both ends of the carriage to prevent them from being suspended in the air.

[0051] The method of using the present invention is as follows: first, the vehicle is prepared, and sufficient water, compressed air, generator fuel and other necessary rescue materials and equipment are loaded on the railway tunnel fire rescue vehicle. Then, a locomotive is used to quickly tow the railway tunnel fire rescue vehicle to the accident site such as a fire, and perform rescue tasks such as fire extinguishing and transporting trapped people. When performing rescue tasks in the tunnel, the railway tunnel fire rescue vehicle should be located at the front end of the locomotive to play the role of smoke exhaust and environmental monitoring of the rescue vehicle. When sensors and cameras monitor and detect dangerous situations, the rescue vehicle should be evacuated in time.
