Description

Technical Field

[0001] This utility model relates to a multi-functional emergency rescue fire truck, belonging to the field of fire equipment technology. Background Technology

[0002] Urban fires present significant challenges in evacuation and rescue, creating escape routes, and confined spaces, resulting in insufficient rescue capacity. In some developed areas, township fire brigades are requesting a reduction in the number of vehicles they operate, necessitating multi-functional vehicles. This is particularly relevant in complex rescue scenarios where large aerial ladder trucks are difficult to access, such as small factories and highways. Therefore, there is an urgent need for new, multi-functional emergency rescue equipment.

[0003] For example, a lifting and emergency fire truck with application number 202011133608.3 has two boom structures. The front boom only supports the lifting ladder and high-altitude spraying functions. Note that the rear folding boom must be operated separately for heavy lifting. This structure is complex and occupies space, failing to effectively improve the vehicle's lifting capacity and overall space. Its operating mode is limited, hindering rapid operation and resulting in low vehicle utilization. The double-boom structure occupies a significant amount of space, leading to a small equipment compartment and preventing further improvement in key operational parameters such as liquid capacity, fire-fighting performance, and equipment storage space.

[0004] It is evident that a multi-functional emergency rescue fire truck is urgently needed to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a multi-functional emergency rescue fire truck. By integrating fire monitors, side ladders and lighting components on the boom of a straight boom crane, it realizes the functions of raising the boom for fire extinguishing and rescue. It maximizes the use of the boom function without increasing the boom size. With the cooperation of the telescopic outrigger assembly, it can effectively support the boom of the straight boom crane, ensure the stability of fire fighting, and effectively cope with various complex rescue scenarios.

[0006] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution:

[0026] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0027] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a multi-functional emergency rescue fire truck, including a vehicle body 1, a turntable 2, a telescopic outrigger assembly 3, and a straight boom crane arm 4, wherein...

[0030] The turntable 2 is installed at the rear of the vehicle body 1;

[0031] The boom 4 of the straight boom crane is mounted on the turntable 2. The boom 4 of the straight boom crane integrates a fire monitor 5, a side ladder 6 and a lighting assembly 7.

[0032] The telescopic outrigger assembly 3 is installed on the bottom side of the turntable 2 and connected to the vehicle body 1.

[0033] In the above technical solution, by integrating fire monitor 5, side ladder 6 and lighting components 7 on the boom 4 of the straight boom crane, the functions of raising for fire extinguishing and raising for rescue are realized. The boom function is maximized without increasing the boom size. Thus, a single lifting boom can perform lifting, rescue and spraying functions. Multifunctional switching control can be achieved without switching controllers. The single boom structure provides more space to arrange tanks and equipment boxes, improving fire protection performance and equipment storage space. At the same time, the telescopic outrigger assembly 3 is set at the bottom of the turntable 2 where the boom 4 of the straight boom crane is installed, which can effectively support the boom 4 of the straight boom crane and ensure the stability of fire protection work.

[0034] Among them, the telescopic outrigger assembly 3 is an outrigger structure with horizontal and vertical outriggers commonly used in existing fire trucks. It can support outrigger-less, vertical outrigger, and fully outrigger operation modes, effectively improving fire rescue efficiency. In narrow, low-altitude areas, the vehicle can quickly perform lifting and spraying operations without outrigger support, with the same operating speed and efficiency as ordinary foam fire trucks. In narrow, high-altitude areas, it can operate with only the vertical outriggers, meeting the requirements for small-span, high-height lifting operations. In open areas and during lifting operations, it can operate with both horizontal and vertical outriggers fully deployed, effectively ensuring the safety and efficiency of vehicle lifting operations.

[0035] The vehicle's operating modes are divided into firefighting operation mode, lifting operation mode, and personnel rescue ladder operation mode. The firefighting operation mode has three working conditions: First, when the outriggers are not supported, the upper vehicle's boom must be fully retracted, and the boom's movement is limited to a certain range; second, when only the vertical outriggers are supported, small-amplitude operations are possible, with the boom's position restricted according to angle and length, allowing operation in certain areas; third, when both horizontal and vertical outriggers are fully supported, large-amplitude operations are possible, and the boom can operate within the entire working range permitted by the vehicle. Example 2

[0036] like Figures 1-3 As shown, the multi-functional emergency rescue fire truck provided in this embodiment differs from the multi-functional emergency rescue fire truck provided in Embodiment 1 in that:

[0037] Because of the adoption of a single-arm structure, the fire truck has more space to arrange relevant fire-fighting equipment, thereby improving fire-fighting performance and equipment placement space. Therefore, it also includes an integrated equipment box 8, which is located in the middle of the vehicle body 1.

[0038] To accommodate the placement of relevant fire-fighting equipment, the system also includes a fire tank 9, a fire pump 10, a foam system 11, and a proportioning mixing system 12, which are installed inside the integrated equipment box 8.

[0039] like Figure 3 As shown, in order to connect the fire pump 10 and the fire monitor 5, a delivery pipeline 13 is also included. The delivery pipeline 13 is installed on the boom 4 of the straight boom crane, and one end of the delivery pipeline 13 is connected to the fire pump 10 through the central rotating body 14, and the other end is connected to the fire monitor 5.

[0040] To supply fire-fighting liquid to the fire monitor 5, the output end of the foam system 11 and the output end of the fire tank 9 are connected to the fire pump 10 through the proportional mixing system 12. The fire pump 10 is driven by the chassis engine of the vehicle body 1 through the drive shaft. The power take-off method of the fire pump 10 is generally also equipped with a power take-off device, which is a common technical means in the field and will not be described in detail here.

[0041] The foam output from the foam system 11 is mixed with the water from the fire tank 9 through the proportioning mixing system 12. The mixture is pressurized by the fire pump 10 and then transported to the high altitude through the lifting device consisting of the lower structure and the boom. Finally, it is sprayed out through the fire monitor 5 set at the end of the boom.

[0042] It should be noted that the foam system 11, the proportioning mixing system 12, and the fire pump 10 are all commonly used fire-fighting equipment in existing fire trucks and are conventional technical means in this field, so they will not be described in detail here.

[0043] It also includes a vacuum pump 15 installed in the integrated equipment box 8. The vacuum pump 15 is connected to the delivery pipeline 13 through a hose. When the vehicle needs to perform external water suction operation, the vacuum pump 15 works first to expel the air in the delivery pipeline 13 and form a negative pressure in the delivery pipeline 13. As a result, the external water source is sucked into the delivery pipeline 13. Then the fire pump 10 is started, and the external water source is continuously sucked in. At this time, the vacuum pump 15 can stop working.

[0044] To connect the side ladder 6 to the boom of the straight boom crane 4, the side ladder 6 is installed on the side of the boom of the straight boom crane 4, and the length of the side ladder 6 is the same as the length of the boom of the straight boom crane 4.

[0045] To enable the connection between the fire monitor 5 and the lighting assembly 6 and the boom of the straight boom crane 4, both the fire monitor 5 and the lighting assembly 6 are installed at the end of the boom of the straight boom crane 4 away from the turntable 2.

[0046] In summary, the multi-functional emergency rescue fire truck provided in this embodiment arranges various fire-fighting equipment in the middle of the vehicle body 1 through an integrated equipment box 8, making reasonable use of the larger vehicle space under the single boom setup, which can effectively improve fire-fighting performance; by installing a vacuum pump 15 in the integrated equipment box 8, the external water suction operation can be achieved through the cooperation of the vacuum pump 15 and the fire pump 10, ensuring fire-fighting performance.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
