[0043] The embodiments of the present disclosure provide a fire truck, such as Figures 1 to 9 As shown, the fire truck comprises a vehicle frame 10, a water storage tank 20, a rotating platform 30, an arm support 40, and a plurality of breaking and dismantling devices. The vehicle frame 10 comprises a first end and a second end along a length direction X, the first end being a first end near the front of the vehicle, and the second end being an end near the rear of the vehicle. The water storage tank 20 is arranged on the vehicle frame 10. The rotating platform 30 is arranged on the vehicle frame 10 and located on a side of the water storage tank 20 near the second end. One end of the arm support 40 is connected to the rotating platform 30, so that the arm support 40 can rotate on the vehicle frame 10. A water spraying device and a connecting piece 410 for assembling the breaking and dismantling devices are arranged on the other end of the arm support 40. The water spraying device is in communication with the water storage tank 20, so as to perform high-altitude spraying through the arm support 40. The plurality of breaking and dismantling devices are connected to the arm support 40 through the connecting piece 410, so as to perform breaking and dismantling rescue. The vehicle frame 10 is provided with a first storage area 110 and a second storage area 120. The first storage area 110 is located on a side of the water storage tank 20 near the first end, and the second storage area 120 is located on a side of the water storage tank 20 near the second end. At least one breaking and dismantling device is stored in each of the first storage area 110 and the second storage area 120.

[0044] The fire truck provided by the present disclosure is provided with a water spraying device and a connecting piece 410 for assembling the breaking and dismantling devices on the free end of the arm support 40. The water spraying device is in communication with the water storage tank 20, so as to perform high-altitude spraying through the arm support 40. The plurality of breaking and dismantling devices are connected to the arm support 40 through the connecting piece 410, so as to perform breaking and dismantling rescue. The vehicle frame 10 is provided with a first storage area 110 and a second storage area 120. The first storage area 110 is located on a side of the water storage tank 20 near the first end, and the second storage area 120 is located between the water storage tank 20 and the rotating platform 30. A plurality of breaking and dismantling devices can be stored in the first storage area 110 and the second storage area 120, so as to improve the emergency rescue capability in response to various working conditions. The fire truck is a high-lift fire truck integrating breaking and dismantling rescue and fire extinguishing, and has high cost performance and practical functions.

[0045] Specifically, as shown in Figures 1 to 7 The first end of the vehicle frame 10 is provided with a driver's cabin 50, and the rotating platform 30 is arranged on the bottom platform away from the rear of the driver's cabin 50. When the fire truck is in standby state, the arm support 40 is retracted to the retracted position and laid flat through the corresponding area between the driver's cabin 50 and the rotating platform 30, so as to realize stable storage of the arm support 40.

[0046] Specifically, the arm 40 includes a telescopic arm, a demolition arm and a water cannon arm. One end of the telescopic arm is rotatably connected to the turntable 30, for example, pivotally connected to the turntable 30 to achieve adjustment of the pitch angle relative to the frame 10. At the same time, the turntable 30 can drive the telescopic arm to rotate 360° through the rotation of the turntable 30, so that the arm 40 can cover the three-dimensional space for rescue operations; the other end of the arm 40 is rotatably connected to the demolition arm and the water cannon arm; the water cannon arm is provided with a water spraying device, and the demolition arm is equipped with a connecting part 410.

[0047] Among them, the arm 40 rotates relative to the frame 10 and rotates between the turntable 30 through the turntable 30, so that the free end of the demolition arm can extend to the first storage area 110 and the second storage area 120, so that the connecting piece 410 on the free end of the demolition arm is connected to the demolition equipment on the first storage area 110 or the second storage area 120.

[0048] Specifically, if Figures 5 to 9 As shown, a storage rack 60 is provided on the first storage area 110 of the vehicle frame 10. The storage rack 60 forms a plurality of storage spaces. A first positioning structure corresponding to the corresponding demolition equipment is formed in each storage space to form a positioning for storing the demolition equipment.

[0049] The first storage area 110 can store a hydraulic shear 710 , a wood grapple 720 and a breaker 730 . The storage rack 60 forms three storage spaces, and the hydraulic shear 710 , the wood grapple 720 and the breaker 730 are respectively placed in one storage space.

[0050] The storage space may be provided with positioning structures corresponding to the structures of the hydraulic shears 710, the wood grabber 720, and the breaker 730, so that they are stably placed in the storage space and prevent shaking. For example, when the demolition tools are installed and fixed, they are aligned using guide holes, which serve as positioning structures.

[0051] The storage rack 60 may be formed by connecting rods, that is, a frame structure, and door panels may be provided on the frame structure to give it a box-like appearance.

[0052] Specifically, if Figures 10 to 12 As shown, the multiple storage spaces formed on the storage rack 60 are arranged in parallel in the width direction Y of the frame 10 to avoid occupying too much space in the length direction X, thereby increasing the length of the water tank 20 and improving the water storage capacity of the water tank 20.

[0053] The angle between the central axes of the demolition equipment placed in two adjacent storage spaces along the second end toward the first end is 4° to 8°. Figure 12As shown, the central axis of the wood grabber 720 can be parallel to the central axis of the vehicle frame 10; the angle ∠A between the central axis of the hydraulic shear 710 and the central axis of the wood grabber 720 is 4° to 8°, such as 4°, 5°, 6°, 7°, 8°, etc.; the angle ∠A between the central axis of the wood grabber 720 and the central axis of the breaker 730 is 4° to 8°, such as 4°, 5°, 6°, 7°, 8°, etc.; since the turntable 30 is usually arranged in the middle position of the width direction Y of the vehicle frame 10, by making the central axis of the wood grabber 720 parallel to the central axis of the vehicle frame 10, the central axis of the arm 40 and the wood grabber 720 can be parallel, which is convenient for the arm 40 to grab; by making the three demolition tool mounting positions installed at an angle, after the arm 40 is rotated, the arm 40 and the central axis of the hydraulic shear 710 or the breaker 730 can be parallel, which is convenient for the arm 40 to grab.

[0054] Specifically, the second storage area 120 is located on the side of the water tank 20 close to the vehicle frame 10, that is, in any area on the side of the water tank 20 close to the vehicle frame 10 other than the area where the turntable 30 is located. For example, the second storage area 120 can be located in the area between the water tank 20 and the turntable 30, or in the rear area of ​​the vehicle on the side of the turntable 30 away from the water tank 20, or in both the area between the water tank 20 and the turntable 30 and the rear area of ​​the vehicle on the side of the turntable 30 away from the water tank 20.

[0055] Among them, such as Figure 8 and Figure 9 As shown, a bucket 750 and a cutting saw 740 are provided on the second storage area 120 of the vehicle frame 10 , and the bucket 750 and the cutting saw 740 are spaced apart and arranged on both sides of the width direction Y of the vehicle frame 10 .

[0056] Among them, a vehicle plate 100, i.e. a sub-frame 10, is provided on the vehicle frame 10, and a second storage area 120 is formed on the vehicle plate 100. A second positioning structure corresponding to the corresponding demolition equipment is formed on the vehicle plate 100 in the second storage area 120 to form a positioning for storing the demolition equipment.

[0057] The storage rack 60 and the turntable 30 may be mounted on the sub-frame 10 , and the sub-frame 10 may further be equipped with horizontal legs, vertical legs and other components.

[0058] Specifically, if Figure 13 and Figure 14 As shown, the connecting piece 410 on the free end of the arm 40 can be a hydraulic clamping device, which is used to grab the target demolition equipment.

[0059] The hydraulic clamping device includes two clamping jaws, and the distance between the two clamping jaws can be adjusted by a hydraulic rod, thereby achieving the purpose of spreading and clamping. The rescue device is provided with two clamping rods that match the hydraulic clamping device. When the rescue device is grasped by the hydraulic clamping device, the two clamping jaws are first placed on a relatively close turntable by the hydraulic rod, and then the two clamping jaws are inserted between the two clamping rods of the rescue device. The two clamping jaws are then spread apart by the hydraulic parts, so that they are clamped on the two clamping rods, thereby achieving the grasping of the rescue device. Of course, those skilled in the art may also adopt other grasping methods, such as clamping, threaded connection, magnetic attraction, etc., and this disclosure does not limit this.

[0060] Specifically, if Figures 1 to 4 As shown, the water tank 20 is located between the driver's cab 50 and the turntable 30. A relief groove 210 is formed on the top surface of the water tank 20, facing away from the vehicle frame 10. The relief groove 210 extends along the longitudinal direction X of the vehicle frame 10. The boom 40 is rotatably connected to the turntable 30 and can be positioned in either a retracted or raised position relative to the vehicle frame 10. When the boom 40 is in the retracted position, the portion of the boom 40 corresponding to the water tank 20 is located in the relief groove 210. The provision of the relief groove 210 prevents the water tank from obstructing the retraction of the boom 40 in the height direction Z, allowing the water tank to be set relatively high, thereby allowing the water tank to store more water or other firefighting liquids.

[0061] When the boom 40 is retracted into the avoidance groove 210, the boom 40 is horizontal relative to the vehicle frame 10. This horizontal position of the boom 40 relative to the vehicle frame 10 improves the stability of the boom 40 during driving of the fire truck. Furthermore, this horizontal position of the boom 40 relative to the vehicle frame 10 assists in determining whether the boom 40 is fully retracted.

[0062] Specifically, a bracket 610 is provided on the frame 10 and is located on a side of the water tank 20 close to the first end; when the boom 40 is in the retracted position, the bracket 610 supports the boom 40 to enhance the stability of the boom 40 in the retracted position.

[0063] Among them, such as Figure 10 and Figure 11 As shown, a bracket 610 is provided on the storage rack 60, so that the storage rack 60 can simultaneously store the demolition equipment and support the arm 40.

[0064] A detection device may be provided on the bracket 610. When the boom 40 is supported by the bracket 610 at the retracted position, the detection device can detect that the boom 40 is at the retracted position and output a detection signal to determine that the boom 40 is at the retracted position.

[0065] The detection device may be a detection switch. When the boom 40 is in the retracted position, the detection switch abuts against the detection switch, and the switch key of the detection switch is pressed to turn it on. The detection switch then outputs a conduction signal, which serves as a detection signal to assist in determining whether the boom 40 is in the retracted position. The detection switch may be, for example, a trigger switch.

[0066] Among them, the detection device can also be a distance sensor, which is fixedly mounted on the bracket 610. By setting the detection angle, when the arm 40 is in the retracted position, the distance sensor can detect the presence of the target detection object (i.e., the arm 40) within the detection range, and at this time, a detection signal can be output to assist in determining whether the arm 40 is in the retracted position. When the arm 40 is not in the retracted position, the distance sensor cannot detect the presence of the target detection object within the detection range to assist in determining that the arm 40 is not in the retracted position. The present disclosure does not limit the specific type of detection device, and any technical solution that realizes the detection of whether the arm 40 is in the retracted position by changing the type of detection device falls within the scope of protection of the present disclosure.

[0067] Specifically, a liquid supply assembly 220 and a liquid outlet assembly 230 are provided on the side of the frame 10 for easy quick connection.

[0068] A water tank 20 and a foam tank can be provided on the vehicle frame 10 so that the vehicle frame 10 can be used as a high-pressure spray truck to perform firefighting operations independently when there is no external water supply source.

[0069] The liquid outlet component 230 may include a water outlet and an external foam supply port, and the liquid supply component 220 may include a water suction port and a water tank filling port.

[0070] The rear end of the vehicle frame 10 is provided with an arm liquid supply port 130 to supply liquid to the pipeline on the arm 40 through the arm liquid supply port 130, thereby achieving the purpose of high-pressure spray fire extinguishing. A plurality of arm liquid supply ports 130 can be provided to connect different liquid supply pipelines.

[0071] A sewage outlet may be provided on the side of the vehicle frame 10 to discharge sewage from the water tank 20 regularly.

[0072] The frame 10 may be provided with a pump body to provide the injection pressure. The pump body may be provided at the rear end of the gearbox on the frame 10 and may be connected to the gearbox in a broken shaft manner.

[0073] A water channel panel may be provided on the side of the vehicle frame 10 to facilitate quick operation of the electronically controlled valves and monitoring of the water channel status.

[0074] Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the features disclosed herein. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.
