Description

Technical Field

[0001] This utility model relates to the field of fire rescue equipment technology, specifically a fire truck-mounted rubber boat tilting device. Background Technology

[0002] In fire and rescue operations, rubber boats are a commonly used rescue tool, playing a particularly important role in water rescues. Currently, a common transportation method involves securing the rubber boat to the roof of a fire truck. However, with this method, once the fire truck arrives at the rescue site, firefighters need to detach the boat from the roof before deploying it to the rescue operation. This process is time-consuming and hinders the rapid commencement of rescue efforts.

[0003] A search revealed two patent documents: CN217945375U, which discloses a trailer for fire and water rescue equipment, and CN221660648U, which discloses a suspension device for fire truck-mounted inflatable boats. These two patents address the purpose of using fire trucks to transport inflatable boats from different perspectives. However, existing transportation methods, such as using trailers, require additional trailers, increasing equipment costs. Furthermore, on uneven roads, this increases the difficulty of operation for the fire truck driver. While suspension devices can provide a stable anchor to prevent slippage or swaying during transport, their disassembly and reassembly remain time-consuming.

[0004] To reduce the space occupied by inflatable boats and to utilize fire trucks for transportation, while also ensuring effective securing of the boats during transport so that firefighters can easily remove them from the fire truck roof, thus facilitating rapid rescue operations, it is essential to provide a unique overturning device that differs from existing technologies.

[0025] The base 1 includes a mounting plate 11, a connecting plate 12, a support base 13, and connectors.

[0026] The connecting components include a first connecting component 14 and a second connecting component 15. The first connecting component 14 is a connecting shaft, and the second connecting component 15 is a scissor-type connecting rod. The connecting shaft is rotatably mounted in a support seat 13 located in the middle of the mounting plate 11, and the lower end of the flipping mechanism 2 is fixedly connected to the connecting shaft. One end of the scissor-type connecting rod is rotatably connected to the support seat 13 located at the end of the mounting plate 11, and the other end is connected to the lower side of the extension mechanism 3. In the specific manufacturing process, to enhance its stability, the second connecting component 15 can be constructed using a four-rod structure to form the scissor-type connecting rod. The specific structure is as follows... Figure 5 As shown, the four rods are interconnected, which enhances the stability between the base 1 and the extension mechanism 3 and prevents instability when the flipping mechanism 2 drives the extension mechanism 3 to rotate.

[0027] Furthermore, using the fire truck-mounted rubber boat tipping device provided in this embodiment, the tipping mechanism 2 includes a tipping arm 21 and a connecting arm 22. The tipping arm 21 is provided in two sets. The lower ends of the two sets of tipping arms 21 are rotatably connected to the support seat 13 in the base 1 through corresponding first connecting members 14, while their upper ends are connected to the upper side of the extension mechanism 3.

The upper end of the telescopic hydraulic rod 61 is connected to the middle part of the tipping arm 21 through a hinge, while its lower end is connected to the mounting plate 11 through a hinge. The telescopic hydraulic rod 61 drives the tipping arm 21 to rotate around the support seat 13 located in the middle of the mounting plate 11.

[0028] Furthermore, in the fire truck-mounted rubber boat tipping device provided in this embodiment, the extension mechanism 3 includes an extension frame 31 and an extension support plate 32.

The specific connection structure is as follows: Figure 6 As shown, its lower side is connected to the second connector 15 in the base 1 via an extension support plate 32, and the specific connection structure is as follows. Figure 5 As shown, the extension mechanism 3, under the action of the flipping arm 21 and the second connecting member 15, can drive the extension frame 31 to tilt.

[0029] Furthermore, in the fire truck-mounted rubber boat tipping device provided in this embodiment, the lifting mechanism 4 includes a first telescopic frame 41 and a second telescopic frame 42. The lifting mechanism 4 forms a telescopic ladder structure through the first telescopic frame 41 and the second telescopic frame 42. The lifting mechanism 4 is slidably connected to the extension frame 31 in the extension mechanism 3 through the first telescopic frame 41. Two sets of telescopic hydraulic cylinders 62 are provided, and the two sets of telescopic hydraulic cylinders 62 are symmetrically installed on the extension frame 31 in the extension mechanism 3, and their hydraulic telescopic ends are connected to the first telescopic frame 41. Under the action of the telescopic hydraulic cylinders 62, the lifting mechanism 4 can move up and down along the extension mechanism 3. The lifting mechanism 4 forms a telescopic ladder structure through the first telescopic frame 41 and the second telescopic frame 42, and the specific structure is similar to that of existing fire truck telescopic ladders, therefore, it is not described in detail here.

[0030] Furthermore, in the fire truck-mounted rubber boat tipping device described in this utility model, the lifting mechanism 5 is configured as a support frame capable of accommodating the rubber boat. The support frame is detachably installed on the second telescopic frame 42 in the lifting mechanism 4 using screws or binding. In practical applications, the lifting mechanism 5 can be manufactured according to the actual size of the rubber boat, as long as it can support the rubber boat; therefore, it is not described in detail here. Example 2

[0031] This embodiment is based on Embodiment 1. Firstly, it facilitates operation by firefighters, and secondly, it reduces safety hazards and prevents the inflatable boat from becoming loose during transportation due to uneven road surfaces, thereby improving its stability. The fire truck-mounted inflatable boat tipping device provided in this embodiment includes a dedicated lock or hook for securing the inflatable boat within the support frame of the lifting mechanism 5. This dedicated lock or hook can be a mechanical structure, or it can be an electronic lock or a hydraulic lock. If an electronic lock or hydraulic lock is used, it is electrically connected to the control system for convenient operation via the control system.

[0032] In practical applications, the control system includes a logic controller and an operating interface. The logic controller is electrically connected to the operating interface, and the operating interface is equipped with control buttons. The control system is electrically connected to the telescopic hydraulic rod 61 and telescopic hydraulic cylinder 62 in the drive mechanism 6, as well as the electronic lock or hydraulic lock, through the logic controller.

[0033] Meanwhile, for convenient monitoring, the control system is also equipped with sensors and cameras. The sensors include position sensors and pressure sensors. Both the position sensors and the camera are installed on the roof of the fire truck. The position sensors are used to monitor the position status of the tilting mechanism 2, and the camera is used to photograph the rubber boat placed in the lifting mechanism 5. The pressure sensor is located in the extension mechanism 3 to monitor the force state of the extension mechanism 3. The position sensors, pressure sensors, and camera are electrically connected to the logic controller and are displayed in real time through the operation interface.

[0034] The fire truck-mounted rubber boat tipping device described in this utility model uses a control system, configured sensors and cameras, and selected telescopic hydraulic rods 61 and telescopic hydraulic cylinders 62, as well as electronic locks or hydraulic locks, all of which are commonly used devices in the prior art. Their application in the tipping device of this utility model is for the purpose of facilitating control and monitoring, without involving any modification to their specific structure. They can simply be purchased from the existing market and installed according to the usage situation, and therefore no detailed description is provided.

[0035] like Figure 7and Figure 8 As shown, in practical applications, the fire truck-mounted rubber boat tilting device described in this utility model utilizes a tilting mechanism 2 and an extension mechanism 3. The tilting mechanism 2 allows the extension mechanism 3 to be tilted and positioned on the side and roof of the fire truck. Under the action of the telescopic hydraulic cylinder 62, the telescopic hydraulic cylinder 62 is activated, pushing the lifting mechanism 4 down to the side closest to the ground. This facilitates securing the rubber boat in the lifting mechanism 5. After the rubber boat is secured, the telescopic hydraulic cylinder 62 is activated again, pulling the lifting mechanism 4 upward. The first telescopic frame 41 in the lifting mechanism 4 retracts into the extension frame 31 in the extension mechanism 3, simultaneously driving the second telescopic frame 42 to retract into the first telescopic frame 31. The frame 41 moves in the direction of movement, thereby causing the rubber boat fixed in the lifting mechanism 5 to move upward along the lifting mechanism 4. Finally, the telescopic hydraulic rod 61 is activated. Since the upper end of the telescopic hydraulic rod 61 is connected to the middle of the tilting arm 21 through a hinge, and its lower end is connected to the mounting plate 11 through a hinge, the telescopic hydraulic rod 61 can drive the tilting arm 21 to rotate around the support seat 13 located in the middle of the mounting plate 11. During the rotation of the tilting arm 21, the extension mechanism 3 can be tilted. The tilting arm 21 drives the extension mechanism 3 to a horizontal state, and the extension mechanism 3 on the side away from the tilting arm 21 is located on the roof of the vehicle, supported by the top of the side of the vehicle roof. In this way, the rubber boat fixed in the lifting mechanism 5 can be located on the roof of the fire truck, achieving the purpose of vehicle-mounted transport.

[0036] Upon reaching the rescue destination, the telescopic hydraulic rod 61 is activated via the control system. This causes the extension mechanism 3, driven by the tilting arm 21, to rotate until it is tilted and positioned on the side of the vehicle. Then, the telescopic hydraulic cylinder 62 is activated. This allows firefighters to easily remove the rubber boat from the lifting mechanism 5 from the ground, rather than manually carrying it from the ground to the roof or removing it from the roof. This significantly improves work efficiency and reduces the physical exertion on firefighters.

[0037] In summary, the tilting device described in this utility model, utilizing existing fire trucks, not only facilitates the transportation of the rubber boats needed to the rescue site via the fire truck, but also makes it easy to remove the rubber boats from the fire truck, which is conducive to rapid rescue operations, thereby reducing the physical exertion of firefighters and meeting the needs of fire rescue missions. Its overall structure is simple, easy to operate and use, and has strong applicability, making it suitable for widespread application.

[0038] Other aspects of this utility model that are not detailed herein are all conventional techniques known to those skilled in the art.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Various modifications and variations can be made by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made using the present utility model should be included within the protection scope of the present utility model.
