DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0034] As shown in Figures 1-10 The application provides a rail type fire-fighting appliance box for an ultra-long tunnel, which comprises a hanger 1, the lower surface of the hanger 1 is fixedly connected with a cabinet body 2, the upper surface of the hanger 1 is provided with a top plate 4, and the top plate 4 and the opposite surface of the hanger 1 are jointly installed with a plurality of support assemblies 3;

[0035] The upper surface of the top plate 4 is fixedly connected with two rotating seats 11, the surface of each rotating seat 11 is rotatably installed with a hanger wheel 12, and the surfaces of the two hanger wheels 12 are jointly slidably provided with a guide rail 13;

[0036] The surface of the hanger 1 is provided with a hanger cable 14 sliding with the top plate 4, one side of the cabinet body 2 is provided with a lifting control assembly 7 for winding the hanger cable 14 to control the lifting of the cabinet body 2, and one side of the lifting control assembly 7 is provided with a deceleration assembly 8 for deceleration control of the lifting control assembly 7.

[0037] The lower surface of the top plate 4 is fixedly connected with a water tank 15, and the lower part of the water tank 15 is communicated with an automatic water cannon 6, and the cabinet body 2 is provided with a water supply assembly 5 for supplying water to the water tank 15.

[0038] After the fire occurs, the fire-fighting cabinet body 2 can be quickly pushed close to the fire source by the cooperation of the guide rail 13 and the hanger wheel 12, so that rapid response and accurate positioning are realized. Compared with the traditional fixed or handheld fire extinguishing device, the efficiency of initial fire control in a complex tunnel environment is greatly improved. Secondly, the whole adopts a suspension design, so that the fire-fighting cabinet body 2 is completely suspended on the top of the tunnel, avoiding occupying the passage space, which not only ensures unobstructed passage, but also does not hinder personnel evacuation, and is especially suitable for emergency evacuation in dense scenes. When the fire is large and it is not easy to approach the fire source, the automatic water cannon 6 maintains a high position injection state to support remote fire extinguishing operation. After the water supply assembly 5 is communicated with the fire hydrant, the water flow can be stably delivered to the water cannon, so as to realize automatic fire extinguishing without manual operation, reduce the exposure risk of personnel in the high-temperature area, and realize remote and on-site collaborative operation, and further ensure the fire control effect.

[0039] Specifically, as shown in Figure 6 and Figure 10 The support assembly 3 includes two slide rails 31 symmetrically fixed on the opposite surfaces of the hanger 1 and the top plate 4, and a plurality of first struts 32 and second struts 33 are arranged on the opposite surfaces of the two slide rails 31. The first struts 32 and the second struts 33 are movably connected by pin shafts at the ends and form a shear structure.

[0040] The support assembly 3 is arranged symmetrically, so that the two first struts 32 and the second struts 33 at the uppermost and lowermost positions can slide in the slide rails 31 at one end. When the first struts 32 and the second struts 33 are moved, they form a scissor structure, which can adapt to the height position of the hanger 1 and maintain support during tilting. The design of the shear structure can effectively support the hanger 1 during the lifting of the fire-fighting cabinet body 2, so that the support between the hanger 1 and the top plate 4 is always stable, avoiding the inclination of the hanger 1 or the inclination of the hanger cable 14 under the action of gravity, thereby ensuring the stable suspension of the cabinet body 2 at different heights.

[0041] In addition, the shear structure can provide better buffering effect during the lifting of the cabinet 2, which helps to disperse the load and maintain the stability of the center of gravity of the system. Even in the case of fire emergency, the support assembly 3 can quickly respond to the movement and height adjustment requirements of the cabinet 2, and smoothly assist the cabinet 2 to reset after operation, ensuring the safety and reliability of the system.

[0042] Specifically, as shown in the figure: Figure 7 The lifting control assembly 7 includes a protective box 71 fixed on one side of the cabinet 2, and the speed reduction assembly 8 is rotatably arranged in the inner wall of the protective box 71. The lifting control assembly 7 further includes a winding roller 72 and an outer disc wheel 75 fixedly connected to the surface of the speed reduction assembly 8.

[0043] One side of the protective box 71 is fixedly connected with a threaded cylinder 73, the surface of the threaded cylinder 73 is threadedly connected with a threaded pressing piece 74, and the inner disc wheel 76 is fixedly connected to the threaded pressing piece 74.

[0044] By arranging the outer disc wheel 75, the outer disc wheel 75 can wind the hoisting cable 14. By using the threaded pressing piece 74, the threaded pressing piece 74 can be pressed into the fast rotating shaft 81 and the slow rotating cylinder 82 under the transmission action of the threaded cylinder 73, so that they cannot rotate relative to each other to achieve locking.

[0045] Specifically, as shown in the figure: Figure 8 The speed reduction assembly 8 includes a slow rotating cylinder 82 rotatably arranged in the inner wall of the protective box 71. The inner wall of the slow rotating cylinder 82 rotatably penetrates a fast rotating shaft 81. One end of the fast rotating shaft 81 is fixedly connected with the outer disc wheel 75. The other end of the fast rotating shaft 81 is connected with a central gear 84. The surface of the central gear 84 is engaged with a plurality of first planetary gears 85. The plurality of first planetary gears 85 are rotatably connected with an engagement ring frame 86 on one side. The surface of the engagement ring frame 86 is engaged with a plurality of second planetary gears 87. The plurality of second planetary gears 87 are rotatably connected on one side of the slow rotating cylinder 82. The surfaces of the first planetary gears 85 and the second planetary gears 87 are jointly engaged with a threaded ring 83. The threaded ring 83 is fixedly connected to one side of the protective box 71.

[0046] The winding roller 72 is fixedly connected to the slow rotating cylinder 82. The outer disc wheel 75 is fixedly connected to one end of the fast rotating shaft 81. The inner wall of the threaded ring 83 is fixedly connected with a shaft frame 88. The engagement ring frame 86 is rotatably arranged in the inner wall of the shaft frame 88.

[0047] The fast rotating shaft 81 of the deceleration assembly 8 is engaged with a plurality of first planetary gears 85 through the central gear 84, and the first planetary gears 85 are engaged with the inner wall of the threaded ring 83 to rotate as a whole around the fast rotating shaft 81, the first planetary gears 85 are engaged with the engaging ring frame 86 to rotate while engaging the second planetary gears 87, the second planetary gears 87 are engaged with the inner wall of the threaded ring 83 to rotate, and the second planetary gears 87 rotate with the slow rotating cylinder 82 to form a large speed difference between the fast rotating shaft 81 and the slow rotating cylinder 82, so that the fast rotating shaft 81 can be rotated to achieve small force to wind the hoisting cable 14, and the cabinet body 2 is kept moving upward, while the slow rotating cylinder 82 rotates to rotate the high-speed shaft when the cabinet body 2 moves downward, so that the slow rotating cylinder 82 does not rotate too fast, and the cabinet body 2 is kept slowly descending.

[0048] Specifically, as shown in Figure 5 The automatic water cannon 6 includes a horizontal rotating pipe 61 rotatably connected to the lower surface of the water tank 15, a vertical rotating pipe 62 rotatably connected to the bottom end of the horizontal rotating pipe 61, a first drive 63 mounted on the surface of the horizontal rotating pipe 61 for driving the rotation thereof, a second drive 64 mounted on the surface of the vertical rotating pipe 62, and a pressurizing pipe 65 fixedly connected to the bottom end of the vertical rotating pipe 62, and an adjusting nozzle 66 provided at one end of the pressurizing pipe 65.

[0049] The first drive 63 and the second drive 64 can respectively drive the deflection angles of the horizontal rotating pipe 61 and the vertical rotating pipe 62, so that they can realize aiming in multiple directions and spraying water flow, and the water flow can be pressurized through the pressurizing pipe 65 and sprayed as water mist through the adjusting nozzle 66.

[0050] Specifically, as shown in Figure 9 The water supply assembly 5 includes a winding disc pipe 51 rotatably installed in the inner wall of the cabinet body 2, a rotating connector pipe 52 rotatably connected to one end of the winding disc pipe 51, and a hose 53 communicating the rotating connector pipe 52 with the water tank 15.

[0051] By providing the winding disc pipe 51, the winding disc pipe 51 can be directly connected to the fire hydrant to make the water flow enter the rotating connector pipe 52 through the winding disc pipe 51, and store the water flow in the water tank 15 through the rotating connector pipe 52, and the water tank 15 can keep providing water flow to the automatic water cannon 6 as a transfer station.

[0052] Specifically, as shown in Figure 6 The surface of the top plate 4 is mounted with a first guide wheel 9 and a second guide wheel 10 for sliding the hoisting cable 14.

[0053] The first guide wheel 9 and the second guide wheel 10 can keep the hoisting cable 14 sliding along the surface and change the force direction of the hoisting cable 14.

[0054] Specifically, as shown in Figure 4As shown: the cabinet body 2 and the top of the hanger 1 are provided with an opening 16 for the water tank 15 to slide, the front of the cabinet body 2 is provided with a cabinet door 17.

[0055] The opening 16 can keep the water tank 15 and the automatic water cannon 6 slide out of the cabinet body 2, and when the cabinet body 2 is lowered, the water tank 15 and the automatic water cannon 6 are always in a higher position.

[0056] When the scheme is used, the two hanger wheels 12 slide in the guide rail 13, which can quickly move personnel to the delivery position after a fire occurs, and then directly push the bottom of the cabinet body 2. The cabinet body 2 slides in the guide rail 13 through the hanger wheels 12 at the top to move quickly, and after being pushed to the fire point position, the inner disc wheel 76 is rotated to make the cabinet body 2 as a whole slowly descend, and when the cabinet body 2 is lowered to the appropriate height, the cabinet door 17 can be opened to take out fire-fighting equipment including fire extinguishers;

[0057] In the process of rotating the inner disc wheel 76, the threaded pressure piece 74 is rotated on the surface of the threaded cylinder 73 and is displaced between the fast rotating shaft 81 and the slow rotating cylinder 82 under the cooperation of the threads, so that the fast rotating shaft 81 and the slow rotating cylinder 82 are in a non-acting relationship with each other, and then the winding roller 72 on the surface of the slow rotating cylinder 82 is rotated to release the hanger cable 14. When the cabinet body 2 is lowered, the hanger cable 14 slides on the surface of the first guide wheel 9 and the second guide wheel 10, and as the length of the hanger cable 14 increases, the hanger 1 and the cabinet body 2 move away from the top plate 4, and the support assembly 3 between the hanger 1 and the top plate 4 is elongated to keep the hanger cable 14 stable and prevent it from tilting or deflecting;

[0058] When the use is completed, the outer disc wheel 75 can be rotated. When the outer disc wheel 75 is rotated, the fast rotating shaft 81 is rotated, the fast rotating shaft 81 revolves through the central gear 84 with the first planetary gear 85, the first planetary gear 85 revolves while rotating slowly with the meshing ring frame 86, the meshing ring frame 86 meshes with the second planetary gear 87 to revolve on the inner wall of the threaded ring 83, and the slow rotating cylinder 82 further rotates slowly, so that the winding roller 72 on the surface of the slow rotating cylinder 82 realizes the winding of the hanger cable 14, and the overall height gradually increases. When the height is appropriate, hold the outer disc wheel 75 with one hand while rotating the inner disc wheel 76. When the inner disc wheel 76 is rotated, the threaded pressure piece 74 on the surface of the threaded cylinder 73 is pressed between the fast rotating shaft 81 and the slow rotating cylinder 82, so that it remains stationary under the action of the friction force between them, and the height remains constant.

[0059] When the fire is larger, as the cabinet 2 is lowered, the water tank 15 is fixed to the lower surface of the top plate 4, so that it slides in the opening 16 and does not move downward with the hanger 1 and the cabinet 2, and the water supply assembly 5 always communicates with the water tank 15 when it moves downward, when the cabinet moves to a certain height, the automatic water cannon 6 is completely exposed and in a high suspension state, when the operator connects the coiled pipe 51 of the water supply assembly 5 to the nearest fire hydrant, the water flows through the coiled pipe 51, the rotating connector 52 and the hose 53 into the water tank 15, at this time, the remote personnel can remotely control the automatic water cannon 6 to cooperate in extinguishing the fire, so that the on-site personnel can use the equipment to extinguish the fire, and at the same time, the remote personnel can cooperate to maximize the control of the fire in the tunnel, and the on-site personnel can cooperate to achieve the fire extinguishing operation.

[0060] The cabinet 2 further includes a mobile power supply, a controller, a signal transceiver, a fire extinguisher, a fire hose, etc., which are not produced and directly installed by purchasing parts, and are not shown in the figure.

[0061] The fire-fighting cabinet 2 is pushed by the operator to quickly approach the fire source through the sliding of the top hanger wheel 12, when the cabinet 2 moves to the target position, the cabinet 2 can slowly descend to an appropriate height under the buffering of the speed reduction assembly 8 after the inner disc wheel 76 is rotated to be unlocked, so that the operator can directly take out the fire-fighting equipment, and the situation that the terrain is blocked and difficult to reach can be avoided, the fire can be timely controlled, the overall volume is large, more fire-fighting equipment can be placed and installed, the whole is suspended overhead, needs to lift the hand to grab and move, and will not occupy the road passage, and the personnel evacuation and walking will not block each other. At the same time, the supporting assembly 3 maintains stability during lifting, effectively avoids the deflection of the hanger cable 14 or the deflection of the hanger 1, so that the overall height is controlled by one hanger cable 14, and the operation safety of the whole system is ensured.

[0062] In addition, through the cooperation of the transmission mechanism of the speed reduction assembly 8, the lifting control assembly 7 provides labor-saving and convenient lifting control, after the fire-fighting operation is completed, the operator can realize the stable lifting of the cabinet 2 through the outer disc wheel 75, so that the cabinet 2 can be safely reset to the original height. Especially when the fire is larger, as the cabinet 2 moves downward, the water tank 15 communicates with the nearest fire hydrant through the water supply assembly 5, and the automatic water cannon 6 is always in a high position and exposed state, which can spray water on the fire source without manual control. This design enables the on-site personnel to use the equipment in the cabinet to extinguish the fire, and the remote control personnel can use the automatic water cannon 6 to cooperate in extinguishing the fire, forming a double fire extinguishing measure. The overall scheme greatly improves the flexibility and rapid response ability of fire control, so that the fire in the tunnel can be effectively controlled, and a more safe and effective guarantee is provided for tunnel rescue.

[0063] The above merely describes preferred embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacements or changes within the technical scope disclosed by the present application and according to the technical solutions and inventive concept of the present application, which should be covered within the protection scope of the present application.
