[0021] The following Figure 1-2 further describes the technical solutions of the present utility model in conjunction with the attached drawings.

[0022] A fire truck, see Figure 1 - Figure 2 , including a chassis 1, a tank 2, a rotary platform support frame 3 and a high and low pressure fire pump system 4 provided on the chassis 1. Among them, the chassis 1, the tank 2, the rotary platform support frame 3 and the high and low pressure fire pump system 4 all adopt existing structures. The fire truck also includes other existing structures such as a cockpit 5, etc., which will not be elaborated here.

[0023] See Figure 1 - Figure 2 , the tank 2, the high and low pressure fire pump system 3 and the rotary platform support frame 4 are arranged in sequence from front to back. A rotary platform 6 is provided on the rotary platform support frame 4. A telescopic boom 7 is provided on the rotary platform 6. A fire cannon 8 is provided at the end of the telescopic boom 7, and a telescopic water pipe 9 connecting the fire cannon 8 and the high and low pressure fire pump system 4. A lower outrigger system structure 10 is provided at the bottom of the rear end of the chassis 1. Preferably, the lower outrigger system structure 10 is an H-shaped support leg. When performing high-altitude fire extinguishing, the telescopic boom 7 extends so that the fire cannon 8 can be lifted to a certain height, and water is taken from the high and low pressure fire pump system 4 and the tank 2 through the telescopic water pipe 9 to perform high-altitude fire extinguishing.

[0024] The above high and low pressure fire pump system 4 is arranged behind the rotary platform support frame 3, making the high and low pressure fire pump system 4 rear-mounted. When water needs to be taken from or the high and low pressure fire pump system 4 needs to be operated, the rotary platform support frame 3 will not cause obstruction, and water can be taken and operation can be directly carried out, which is more convenient to use. In the layout of the vehicle function system in the past, due to the limitation of the upper outrigger system, the high and low pressure fire pump system 4 could not be arranged at the rear of the vehicle. The support leg of the present utility model is the lower outrigger system structure 10, which is arranged at the bottom of the rear end of the chassis 1, avoiding the problem that it affects the rear-mounted of the high and low pressure fire pump system 4.

[0025] In this embodiment, a fire ladder 11 is provided on the telescopic boom 7, and a climbing ladder 12 is provided at the rear end of the fire truck. The rescued person can climb from the high-rise building to the fire truck through the fire ladder 11, and then climb to the ground through the climbing ladder 12, improving the rescue efficiency. And with the high and low pressure fire pump system rear-mounted and the rotary platform support frame 3 arranged behind the high and low pressure fire pump system 4, when the rescued person climbs onto the fire truck from the fire ladder 11, the top of the high and low pressure fire pump system 4 can provide a place to step on, facilitating the rescued person to climb downward and turn in the middle on the fire truck.

[0026] Furthermore, a box body 13 is provided outside the high and low pressure fire pump system 4. The box body 13 can not only cover the high and low pressure fire pump system 4, but also provide a storage space. In addition, the top of the box body is flat, facilitating the rescued person to climb downward and turn in the middle on the fire truck.

[0027] In this embodiment, there are two ladder trucks 11, which can improve the rescue efficiency. Further, the two ladder trucks are respectively located on both sides of the telescopic water pipe 9. When multiple rescued persons climb down along the two ladder trucks, the two ladder trucks 11 will not affect the climbing due to being too close to each other, ensuring the climbing speed and safety.

[0028] In this embodiment, the rotary table support frame 3 is welded to the chassis 1, which improves the connection strength and reliability.

[0029] In this embodiment, the telescopic boom 7 adopts a three-section synchronous telescopic boom structure, greatly shortening the basic boom length, enabling the position of the rotary table to move forward, and avoiding the excessive length of the telescopic boom. The cross-section of the telescopic boom is hexagonal, and a lighting lamp, a piercing mechanism, etc. are also provided at its front end.

[0030] In this embodiment, the rotary table 6 can rotate 360°, and its structure can be designed according to actual needs.

[0031] In this embodiment, a compartment is also provided outside the tank body 2, and a rolling door, a flip pedal, warning lights and signs, decorative components, etc. are attached to the outside of the compartment, which are all existing structural designs.

[0032] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here.
