[0060] like Figure 1 As shown, in one embodiment of the present disclosure, the fire fighting vehicle provided by the present disclosure includes a vehicle body 100, a boom assembly 200 and a water cannon 300.

The structure, connection mode and functional relationship of each main component of the high-rise fire truck proposed in the present disclosure will be described in detail below in conjunction with the above drawings.

[0062] like Figures 1 to 7As shown, in one embodiment of the present disclosure, the arm assembly 200 is arranged on the vehicle body 100 via the rotating platform 130, and the arm assembly 200 can be driven to rotate relative to the vehicle body 100 as a whole through the rotating platform 130. For example, the vehicle body 100 may include a frame 110 and a carriage 120, the carriage 120 is arranged on the frame 110, and the rotating platform 130 is arranged on the carriage 120. The water cannon 300 includes a gun body 310 and a gun head 320. One end of the gun body 310 is movably connected to the end of the arm assembly 200 (for example, the top end of the arm assembly 200 after being unfolded, that is, the end farthest from the rotating platform 130), and the gun body 310 is driven by the gun body driving mechanism and can swing vertically relative to the arm assembly 200, and the so-called "vertical" means that the swinging surface of the gun body 310 is perpendicular to the plane where the chassis of the vehicle body 100 is located, for example, in the vertical direction. According to this, when the arm assembly 200 is folded to a horizontal state, the gun body 310 can swing relative to the arm assembly 200, so that the gun body 310 and the arm assembly 200 have an angle that is not 0 and 180 degrees, for example, the gun body 310 is swung to a state where the arm assembly 200 is perpendicular to the gun body 310, so as to achieve driving and pumping water. The gun head 320 is movably connected to the other end of the gun body 310, and the gun head 320 is driven by the gun head 320 driving mechanism to rotate and pitch relative to the gun body 310. Through the above design, the present disclosure utilizes the relative swing design of the gun body 310 and the arm in the vertical direction, which can realize the high-rise fire truck driving and pumping water at the same time, does not take up the time of moving the car, and can extinguish the fire while moving the car, effectively solving the shortcoming of the high-rise fire truck being unable to operate when moving the car, and expanding the practical function of the high-rise fire truck. In addition, the present disclosure utilizes the design of relative rotation and pitch of the gun body 310 and the gun head 320, which can increase the spraying and extinguishing range of the water cannon 300 and improve the fire extinguishing effect. In addition, the present invention has a simple structure and low cost.

[0063] like Figures 5 to 7 As shown, in one embodiment of the present disclosure, the gun body 310 includes a first part 311 and a second part 312, and the gun head 320 driving mechanism includes a rotation driving mechanism 341 and a pitch driving mechanism 342. Specifically, one end of the first part 311 is movably connected to the end of the arm assembly 200, and the first part 311 is driven by the gun body driving mechanism to swing vertically relative to the arm assembly 200. The other end of the first part 311 is movably connected to one end of the second part 312, and the second part 312 is driven by the rotation driving mechanism 341 to rotate relative to the first part 311. The gun head 320 is movably connected to the other end of the second part 312, and the gun head 320 is driven by the pitch driving mechanism 342 to pitch relative to the second part 312. Through the above design, the present disclosure can realize the rotation adjustment and pitch adjustment of the water cannon 300 itself, increase the spraying fire extinguishing range of the water cannon 300, and improve the fire extinguishing effect.

[0064] like Figure 5As shown, in one embodiment of the present disclosure, the high-rise fire truck proposed in the present disclosure may also include a mounting seat 351 and a connecting plate 352. The mounting seat 351 is movably connected to the end of the boom assembly 200, and the mounting seat 351 is driven by the gun body driving mechanism and can swing vertically relative to the boom assembly 200. One end of the connecting plate 352 is connected to the mounting seat 351, and the other end extends to one side in the horizontal direction, and one end of the gun body 310 is connected to the other end of the connecting plate 352. Through the above design, the present disclosure uses the mounting seat 351 and the connecting plate 352 to realize the movable arrangement of the water monitor 300 at the end of the boom assembly 200, which can facilitate the arrangement of the water pipe connected to the water monitor 300 on one side of the boom assembly 200 in the horizontal direction. When flipping, the boom assembly 200 is connected to the water monitor 300 using the mounting seat 351 and the connecting plate 352 to realize synchronous flipping linkage.

[0065] like Figure 6 As shown, in one embodiment of the present disclosure, the gun barrel driving mechanism may be a cylinder, which includes a cylinder barrel and a cylinder rod. A protective plate 331 may be provided at the bottom of the end of the arm support assembly 200, for example, a rib plate is welded to the bottom of the end of the arm support assembly 200 to serve as the protective plate 331. The position of the gun barrel driving mechanism not marked in the drawings may be roughly referred to Figure 6 The position of the protective plate 331 is shown. Accordingly, in the normal retracted state, the protective plate 331 can protect the water cannon 300. On this basis, the cylinder is arranged at the bottom of the protective plate 331, the cylinder rod can be extended and retracted by the cylinder, and the end of the cylinder rod extending out of the cylinder is rotatably connected to the gun body 310. Specifically, when the above-mentioned mounting seat 351 and connecting plate 352 are included, the end of the cylinder rod extending out of the cylinder can also be rotatably connected to the mounting seat 351, thereby realizing an indirect rotation connection between the cylinder rod and the gun body 310 via the mounting seat 351 and the connecting plate 352. For example, Figure 3 In the process, the cylinder rod is retracted so that the water monitor 300 is substantially extended in a direction parallel to the arm assembly 200 (for example, the first arm 210), and the fire truck can be in a normal driving state at this time. Figure 4 In the process, the cylinder rod extends from the cylinder barrel so that the water cannon 300 is rotated vertically relative to the boom assembly 200 to a substantially vertical state, so that the water cannon can perform water pumping operations while driving.

[0066] In one embodiment of the present disclosure, the gun body driving mechanism, the slewing driving mechanism 341 and the pitching driving mechanism 342 can all be coupled to the control unit of the high-rise fire truck. Accordingly, when the gun body driving mechanism drives the water monitor 300 to reach a vertical state relative to the arm assembly 200, the control unit can further control the slewing driving mechanism 341 and the pitching driving mechanism 342 to adjust the gun head 320 of the water monitor 300 to pitch, swing horizontally, etc., so as to cover the fire extinguishing range, thereby completing the function of driving and pumping water. Among them, the control unit can be a control component such as a control cabinet electrically connected to the above-mentioned driving mechanism through a cable, or it can be a wireless remote control or application software on a mobile device.

[0067] like Figure 6 As shown, in one embodiment of the present disclosure, the water monitor 300 may be connected to a water pipe, for example, the water monitor 300 may be connected to a water tank or used to connect to an external water source via the water pipe. The water pipe includes a main pipe 410 and a first connecting pipe 420. The first connecting pipe 420 is a hose, and the first connecting pipe 420 is arranged at the end of the boom assembly 200. One end of the first connecting pipe 420 is connected to the main pipe 410, and the other end is connected to the water monitor 300. Through the above design, the present disclosure can use the first connecting pipe 420 to bend and deform when the water monitor 300 and the boom assembly 200 move relative to each other to adapt to the adjustment action of the water monitor 300. Among them, in the folded state, the internal space of the water pipe does not have the situation of closing, deformation, etc., and is in a normally open state, and when a hose is used, the liquid flow will not be prevented due to factors such as the turning radius.

[0068] Based on the design that the water monitor 300 is connected to a water pipe and the water pipe includes a main pipe 410 , in one embodiment of the present disclosure, the main pipe 410 can be fixed to the boom assembly 200 via a pipe clamp 401 .

[0069] Based on the design that the water monitor 300 is connected to a water pipe and the water pipe includes a first connecting pipe 420, in one embodiment of the present disclosure, the first connecting pipe 420 may be a steel hose or a rubber hose.

[0070] like Figure 5 As shown, based on the design that the water monitor 300 is connected to a water pipe and the water pipe includes a main pipe 410 and a first connecting pipe 420, in one embodiment of the present disclosure, the main pipe 410 and the first connecting pipe 420 can be connected via a connecting flange.

[0071] like Figure 8As shown, in one embodiment of the present disclosure, the transmission mechanism of the elevated fire truck proposed in the present disclosure may include a main transmission mechanism and a water pump transmission mechanism. Specifically, the gearbox of the elevated fire truck itself has a set of main transmission mechanisms, and the main transmission mechanism includes a main transmission shaft 111, which is used to connect the chassis transmission shaft to drive each wheel to rotate and realize the movement of the entire vehicle. In addition, the gearbox may also have a set of transmission interfaces, namely a water pump transmission mechanism, which includes a water pump transmission shaft 112, through which the water pump transmission shaft 112 can be connected to the water pump and drive the water pump to make the water in the water tank pass through the water pipe to reach the water cannon 300 for water spraying.

[0072] like Figures 1 to 4 , Fig. 9 As shown, in one embodiment of the present disclosure, the boom assembly 200 may include a first boom 210 and a second boom 220. One end of the first boom 210 is movably connected to the rotary platform 130, and the first boom 210 can swing vertically relative to the rotary platform 130. One end of the second boom 220 is movably connected to the other end of the first boom 210, and the second boom 220 can swing vertically relative to the first boom 210, and the other end of the second boom 220 is the end of the boom assembly 200.

[0073] like Fig.10 As shown, based on the design that the boom assembly 200 includes the first boom 210 and the second boom 220, in one embodiment of the present disclosure, the water monitor 300 is still connected to a water pipe and the water pipe includes a main pipe 410 as an example, the main pipe 410 can specifically include a first pipe 411 and a second pipe 412, the first pipe 411 is arranged corresponding to the first boom 210, and the second pipe 412 is arranged corresponding to the second boom 220. Among them, the first pipe 411 can be arranged on one side of the first boom 210 in the horizontal direction, the second pipe 412 can be arranged on one side of the second boom 220 in the horizontal direction, and the first pipe 411 and the second pipe 412 can be located on the same side of the boom assembly 200 in the horizontal direction. On this basis, the first pipe 411 and the second pipe 412 can be connected via two curved pipe structures 413 connected by rotation, and the curved pipe structure 413 is located on one side of the connection between the first boom 210 and the second boom 220 in the horizontal direction. In some embodiments, the first pipe 411 and the second pipe 412 may also be connected via a connecting pipe such as a hose, and the present embodiment is not limited thereto. In addition, a set of elbows may also be provided at the position of the main pipe 410 corresponding to the end of the boom assembly 200, that is, one elbow is connected to the water monitor 300, and the other elbow is connected to the main pipe 410, and the two elbows are rotatably connected.

[0074] See also Figures 12 to 17 , Fig.12 and Fig.132 and 3 respectively show three-dimensional schematic diagrams of a partial structure of a fire-lift truck in another exemplary embodiment that can embody the principles of the present disclosure in two different states; Fig.14 A three-dimensional schematic diagram of the first swing driving mechanism 223 is representatively shown in FIG. Fig.15 A schematic diagram of an application scenario of a high-rise fire truck for high-rise fire fighting is representatively shown in FIG. Fig.16 Representatively shown in Fig.15 A top view of Fig.17 A schematic diagram of the principle of the swing locking mechanism 226 is representatively shown in FIG.

[0075] like Figures 12 to 16 As shown, in one embodiment of the present disclosure, the arm assembly 200 still includes a first arm 210 and a second arm 220 as an example, and the second arm 220 can include at least a lower folding arm 221 and an upper folding arm 222. One end of the lower folding arm 221 is movably connected to the other end of the first arm 210, and the lower folding arm 221 can swing vertically relative to the first arm 210. One end of the upper folding arm 222 is movably connected to the other end of the lower folding arm 221, and the other end of the upper folding arm 222 is the end of the arm assembly 200, and a swing driving mechanism is provided between the lower folding arm 221 and the upper folding arm 222. Driven by the swing driving mechanism, the upper folding arm 222 can swing bidirectionally relative to the lower folding arm 221. For example, the upper folding arm 222 can swing left and right relative to the lower folding arm 221, that is, in the extension direction of the lower folding arm 221, the upper folding arm 222 takes one end connected to the lower folding arm 221 as an axis, and the other end can swing relatively to the left or right. Through the above design, the present invention adopts a multi-section structure for the second arm 220 that can swing relatively left and right, further expanding the swing angle range of the water cannon 300 in the horizontal direction. The self-swinging of the second arm 220 is a supplement between the swing range of the water cannon 300 and the swing range of the rotating platform 130, increasing the spraying fire extinguishing range of the water cannon 300 and improving the fire extinguishing effect. At the same time, it can make up for the deficiencies of the water cannon 300 and the rotating platform 130 in the control of the fire extinguishing range and realize precise fire extinguishing.

[0076] Specifically, when the high-rise fire truck proposed in the present disclosure is driving and pumping water, it can be suitable for ground firefighting operations. When performing high-altitude firefighting operations, the boom assembly 200 is unfolded and the water cannon 300 is used to pump water. In addition, if the fire range is large, the pitching and tilting of the boom assembly 200 and the pitching and rotation of the water cannon 300 may not meet the actual firefighting needs. At this time, the horizontal swing of the boom assembly 200 can further expand the water pumping and firefighting range. However, in the existing scheme, the horizontal swing of the boom can only be achieved by the turntable connected to its lower end, but the accuracy of the swinging action is poor. The swinging of the turntable will cause the entire boom to shake. Moreover, since the boom is relatively long after being unfolded, a small rotation of the turntable will cause a large swing at the end of the boom. From the perspective of fire extinguishing control, it is not perfect and it is difficult to achieve accurate fire extinguishing. In this regard, in this case, the second boom 220 adopts a multi-stage swing design, which can improve the accuracy of the swing adjustment of the boom assembly 200 itself, reduce shaking, improve the level of fire extinguishing control, and facilitate accurate fire extinguishing.

[0077] As mentioned above, since the second boom 220 adopts a horizontal self-swinging design, when the boom is recovered, it can perform a return to center identification (i.e., a reset function). Specifically, Fig.11 Wherever you go Fig.13 As shown, the manual reset control requires that when the boom assembly 200 is retracted, the upper folding arm 222 is controlled to rotate back to the middle position, and the entire second boom 220 is in a straight line. Only then can all the booms be retracted. Otherwise, the boom is not allowed to implement one-key retraction control, because the horizontal swing is not reset and it will collide with the lower folding arm 221 when it is retracted. Furthermore, an automatic reset function can also be added to the one-key recovery, that is: when using the boom assembly 200 for one-key recovery, the sensor first detects whether there is an angle difference between the upper folding arm 222 and the lower folding arm 221. If so, the reset to center function is automatically started, and then the first boom 210 is retracted (for example, the telescopic cylinder used to drive the extension and retraction of the first boom 210 is retracted), and then the second boom 220 is retracted, and finally the first boom 210 is lowered to complete the recovery of all boom assemblies 200).

[0078] like Figure 12 to Figure 14 As shown, based on the design that the second arm 220 includes a lower folding arm 221 and an upper folding arm 222, in one embodiment of the present disclosure, the lower folding arm 221 and the upper folding arm 222 can be directly connected. The so-called "direct connection" means that no other arm structure (for example, Fig.18 and Fig.19The upper folding arm 222 is directly rotatably connected to the lower folding arm 221 by a swing mechanism. A first swing driving mechanism 223 is provided between the lower folding arm 221 and the upper folding arm 222. The upper folding arm 222 can swing left and right relative to the lower folding arm 221 by the drive of the first swing driving mechanism 223.

[0079] like Fig.14 As shown, in one embodiment of the present disclosure, the first swing drive mechanism 223 may include a fixed seat 2231 and a rotating mechanism 2232, wherein the fixed seat 2231 is disposed on one of the lower folding arm 221 and the upper folding arm 222, and the rotating mechanism 2232 is rotatably disposed on the fixed seat 2231 and connected to the other of the lower folding arm 221 and the upper folding arm 222. For example, the first swing drive mechanism 223 may specifically adopt a rotating oil cylinder. An oil inlet pipe and an oil return pipe are connected to the side of the oil cylinder, and the horizontal rotation direction of the oil cylinder can be controlled. Through the connection of such a rotating oil cylinder, the left and right swing of the upper folding arm 222 relative to the lower folding arm 221 can be directly controlled, and there is no need to reset before performing the next action, which is easier to use in terms of operation.

[0080] like Fig.12 and Fig.13 As shown, in one embodiment of the present disclosure, the water monitor 300 is connected to a water pipe, the water pipe includes a main pipe 410, the main pipe 410 includes a first pipe 411 and a second pipe 412, the first pipe 411 is arranged corresponding to the first arm 210, and the second pipe 412 is arranged corresponding to the second arm 220. On this basis, the second pipe 412 can be arranged on the top of the second arm 220. Through the above design, the present disclosure can avoid interference between the arm assembly 200 and the water pipe when swinging.

[0081] for Fig.12 and Fig.13 The embodiment shown, an example of its specific rotation range can be referred to Fig.15 and Fig.16 As shown, the rotating platform 130 of the aerial fire truck can achieve 360° rotation, the water monitor 300 swing angle is ±45°, and the second arm 220 itself swings at ±45°, that is, the overall swing angle of the water monitor 300 can reach ±90°, that is, an angle range of 180°. On this basis, when performing firefighting operations, the aerial fire truck does not need to move twice, and only needs to stop once to cover the firefighting range of 180° on the side of the building, achieving full coverage of the firefighting angle of the building. In contrast, when the second arm 220 cannot swing horizontally, the overall swing angle of the water monitor 300 is only ±45°, that is, an angle range of 90°.

[0082] See also Figures 18 to 20 , Fig.18 and Fig.192 and 3 respectively show top views of a partial structure of a fire-lift truck in another exemplary embodiment that can embody the principles of the present disclosure in two different states; Fig. 20 The figure shows a representative top view of an application scenario of a fire fighting truck during high-altitude fire fighting.

[0083] like Fig.18 and Fig.19 As shown, in one embodiment of the present disclosure, the arm assembly 200 still includes the first arm 210 and the second arm 220 as an example, and the second arm 220 includes the lower folding arm 221 and the upper folding arm 222 as an example, and the second arm 220 can also include a middle folding arm 224. Specifically, one end of the middle folding arm 224 is movably connected to the other end of the lower folding arm 221, and a second swing driving mechanism 225 is provided between the middle folding arm 224 and the lower folding arm 221. Through the drive of the second swing driving mechanism 225, the middle folding arm 224 can swing in one direction relative to the lower folding arm 221. The other end of the middle folding arm 224 is movably connected to one end of the upper folding arm 222, and a third swing driving mechanism is provided between the middle folding arm 224 and the upper folding arm 222. Through the drive of the third swing driving mechanism, the upper folding arm 222 can swing in another opposite direction relative to the middle folding arm 224. For example, the middle folding arm 224 can swing to the left (or right) relative to the lower folding arm 221, that is, in the extension direction of the lower folding arm 221, the middle folding arm 224 uses one end connected to the lower folding arm 221 as an axis, and the other end (including the upper folding arm 222 connected to the other end) can swing relatively to the left (or right). And, the upper folding arm 222 can swing to the right (or left) relative to the middle folding arm 224, that is, in the extension direction of the middle folding arm 224, the upper folding arm 222 uses one end connected to the middle folding arm 224 as an axis, and the other end (including the water cannon 300 connected to the other end) can swing relatively to the right (or left). In other words, different from Fig.12 and Fig.13 In the embodiment shown, the lower folding arm 221 and the upper folding arm 222 are directly connected. In this embodiment, a middle folding arm 224 is further provided between the lower folding arm 221 and the upper folding arm 222. Fig.12 and Fig.13 The embodiment shown adopts that the second arm 220 itself has a swing point (i.e., the rotation connection position of the lower folding arm 221 and the upper folding arm 222). Fig.18 and Fig.19The embodiment shown adopts that the second arm 220 itself has two swing points (i.e., the rotation connection position of the lower folding arm 221 and the middle folding arm 224 and the rotation connection position of the middle folding arm 224 and the upper folding arm 222). Accordingly, unlike the previous embodiment that uses one swing point to achieve the left and right swing at the same time, this embodiment uses one swing point to achieve the left swing and uses another swing point to achieve the right swing. On this basis, since the second arm 220 will produce a rotation angle offset when the two swing points swing at the same time, the present disclosure further designs the control strategy of the first swing drive mechanism 223 and the second swing drive mechanism 225, so that: when the middle folding arm 224 swings relative to the lower folding arm 221, the middle folding arm 224 and the upper folding arm 222 remain in a state of extending in the same direction, and when the upper folding arm 222 swings relative to the middle folding arm 224, the middle folding arm 224 and the lower folding arm 221 remain in a state of extending in the same direction.

[0084] In one embodiment of the present disclosure, the second swing drive mechanism 225 may be a cylinder, that is, an oil cylinder is provided between the lower folding arm 221 and the middle folding arm 224 , and another oil cylinder is provided between the middle folding arm 224 and the upper folding arm 222 .

[0085] Based on the design that the second arm 220 adopts a multi-stage structure and can swing horizontally by itself, Fig.17 As shown, in some embodiments of the present disclosure, the driving mechanism (eg Fig.12 and Fig.13 The swing drive mechanism shown, Fig.18 and Fig.19 The first swing drive mechanism 223 and the second swing drive mechanism 225 shown in the figure can be provided with a swing locking mechanism 226, which can lock the relevant drive mechanism when the water cannon 300 is pumping water, so as to lock the relative position between the lower folding arm 221 and the upper folding arm 222, so that the second arm 220 can be locked to maintain its current swing angle when the water cannon 300 is pumping water, thereby avoiding the sliding (mis-swinging) of the rotating connection position of the second arm 220 itself due to the recoil of the water cannon 300 pumping water, and better aiming at the predetermined fire extinguishing position for precise fire extinguishing.

[0086] like Fig.12 and Fig.13 , Fig.18 and Fig.19As shown, in some embodiments of the present disclosure, taking the water monitor 300 connected with a water pipe and the water pipe including the main pipe 410 as an example, the main pipe 410 may include a first pipe 411 and a second pipe 412, the first pipe 411 is arranged corresponding to the first arm 210, and the second pipe 412 is arranged corresponding to the second arm 220. On this basis, the second pipe 412 may include at least two sub-pipes 4121 and at least one second connecting pipe 4122, for example, when the second arm 220 is a two-stage structure (i.e., including a lower folding arm 221 and an upper folding arm 222), the number of sub-pipes 4121 is two and the number of second connecting pipes 4122 is one, and when the second arm 220 is a three-stage structure (i.e., including a lower folding arm 221, an upper folding arm 222 and a middle folding arm 224), the number of sub-pipes 4121 is three and the number of second connecting pipes 4122 is two. Among them, a second connecting pipe 4122 is connected between two adjacent sub-tubes 4121, and the second connecting pipe 4122 is a soft tube. The second connecting pipe 4122 is arranged corresponding to the connection between the lower folding arm 221 and the upper folding arm 222 (or the connection between the lower folding arm 221 and the middle folding arm 224, and the connection between the middle folding arm 224 and the upper folding arm 222). Through the above design, the present disclosure can utilize the second connecting pipe 4122 to bend and deform when the sections of the second arm frame 220 swing relative to each other, so as to adapt to the adjustment action of the second arm frame 220.

[0087] Based on the design that the main pipe 410 includes the second pipe 412 and the second pipe 412 includes the second connecting pipe 4122, in one embodiment of the present disclosure, the second connecting pipe 4122 may be a steel hose or a rubber hose.

[0088] for Fig.18 and Fig.19 The embodiment shown, an example of its specific rotation range can be referred to Fig. 20 As shown, the rotating platform 130 of the fire truck can achieve 360° rotation, the water monitor 300 swings at an angle of ±45°, and the second arm 220 swings at an angle of ±30°, that is, the overall swing angle of the water monitor 300 can reach ±75°, that is, an angle range of 150°. In contrast, when the second arm 220 cannot swing horizontally, the overall swing angle of the water monitor 300 is only ±45°, that is, an angle range of 90°.

[0089] It should be noted that the fire-lift trucks shown in the drawings and described in this specification are only a few examples of many fire-lift trucks that can adopt the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are by no means limited to any details or any components of the fire-lift trucks shown in the drawings or described in this specification.

[0090] In summary, the high-rise fire truck proposed in the present disclosure includes a vehicle body 100, a boom assembly 200 and a water cannon 300, and the boom assembly 200 is arranged on the vehicle body 100 via a rotating platform 130. Among them: the water cannon 300 includes a gun body 310 and a gun head 320. One end of the gun body 310 is movably connected to the end of the boom assembly 200, and the gun body 310 is driven by the gun body driving mechanism to swing vertically relative to the boom assembly 200. When the boom assembly 200 is folded into a horizontal state, the gun body 310 can swing to a state perpendicular to the boom assembly 200 to achieve driving and pumping water. The gun head 320 is movably connected to the other end of the gun body 310, and the gun head 320 is driven by the gun head 320 driving mechanism to rotate and pitch relative to the gun body 310. Through the above design, the disclosure utilizes the relative swing design of the gun body 310 and the arm in the vertical direction to realize the elevated fire truck driving and pumping water at the same time, thereby expanding the practical function of the elevated fire truck. In addition, the disclosure utilizes the relative rotation and pitch design of the gun body 310 and the gun head 320 to increase the spraying and extinguishing range of the water monitor 300 and improve the fire extinguishing effect.
