Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

[0043] Combine the following Figures 1 to 5 A series-connectable lifting module and a fire fighting machine provided by an embodiment of the present invention are described. It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute any particular limitation to the present invention.

[0044] The embodiment of the present invention provides a series-connectable lifting module 200, such as Figure 2 , Figure 4 and Figure 5 As shown, the serially connectable lifting module 200 includes: a frame 202, a walking device 201, a support assembly 300, a serial assembly and a lifting assembly.

[0045] The walking device 201 is connected to the vehicle frame 202. The support assembly 300 is connected to the vehicle frame 202. The support assembly 300 can be supported on the ground. The series assembly is used to connect a plurality of series-connectable lifting modules 200 in series. The lifting assembly is connected to the vehicle frame 202. For example, the series assembly can be connected to the support assembly 300. Alternatively, the series assembly can be installed on the vehicle frame 202.

[0046] Through this structural setting, the lifting modules 200 that can be connected in series can independently perform rescue work. Alternatively, multiple lifting modules 200 that can be connected in series can be connected in series through a series assembly, so that multiple lifting modules 200 that can be connected in series can work together and increase the working range of the rescue. As a result, the lifting modules 200 that can be connected in series can achieve the effect of increasing their working range. At the same time, the lifting modules 200 that can be connected in series can be applied to both small rescue sites and large rescue sites, and have high versatility and flexibility.

[0047] In one embodiment of the present invention, the support assembly 300 includes a first support portion 301 and a second support portion 302 rotatably connected to one side of the lifting module 200 , and a third support portion 303 and a fourth support portion 304 rotatably connected to the other side of the lifting module 200 .

[0048] Further, in one embodiment of the present invention, the first support portion 301, the second support portion 302, the third support portion 303 and the fourth support portion 304 have the same structure, and all include a connecting arm 305 and a telescopic support leg 308. The series assembly includes a telescopic male connector 307 and a telescopic female connector 306.

[0049] The connecting arm 305 is rotatably connected to the vehicle frame 202. The telescopic female head 306 is connected to the connecting arm 305. Moreover, the telescopic female head 306 can be telescoped along the axis direction of the connecting arm 305. The telescopic support leg 308 is connected to the telescopic female head 306, and the telescopic support leg 308 can be telescoped and supported on the ground. The telescopic male head 307 can be retracted to the inside of the telescopic female head 306 or extended to the outside of the telescopic female head 306 along the axis direction of the telescopic female head 306.

[0050] For example, Figure 2 and 4As shown, the support assembly 300 includes a first support part 301, a second support part 302, a third support part 303 and a fourth support part 304. The first support part 301 and the second support part 302 are connected to one side of the frame 202 by rotation at intervals; the third support part 303 and the fourth support part 304 are connected to the other side of the frame 202 by rotation at intervals. When the lifting module 200 needs to perform disaster relief work, the lifting module 200 is first allowed to independently walk to the disaster relief work site, and then the support angles of the first support part 301, the second support part 302, the third support part 303 and the fourth support part 304 are adjusted so that the lifting module 200 is stably supported on the ground. For example, the first support part 301, the second support part 302, the third support part 303 and the fourth support part 304 can form an X-shaped support. Or for example, the angle between the length extension direction of the first support portion 301 and the length extension direction of the lifting module 200 is 45°, the angle between the length extension direction of the second support portion 302 and the length extension direction of the lifting module 200 is 45°, and the angle between the length extension direction of the first support portion 301 and the length extension direction of the second support portion 302 is 90°. Similarly, the angle between the length extension direction of the third support portion 303 and the length extension direction of the lifting module 200 is 45°, the angle between the length extension direction of the fourth support portion 304 and the length extension direction of the lifting module 200 is 45°, and the angle between the length extension direction of the third support portion 303 and the length extension direction of the fourth support portion 304 is 90°.

[0051] Furthermore, Figure 1 and Figure 5 As shown, in one embodiment of the present invention, two lifting modules 200 that can be connected in series are included. When the two lifting modules 200 that can be connected in series need to work together, as shown in FIG. Figure 5 As shown, firstly, two lifting modules 200 that can be connected in series are parked side by side at the disaster relief work site, and then the support angles of the first support part 301 and the second support part 302 of one of the lifting modules 200 that can be connected in series are adjusted. For example, the angle between the length extension direction of the first support part 301 and the length extension direction of the lifting module 200 is 45°, the angle between the length extension direction of the second support part 302 and the length extension direction of the lifting module 200 is 45°, and the angle between the length extension direction of the first support part 301 and the length extension direction of the second support part 302 is 90°.

[0052] Continue to adjust the third support portion 303 and the fourth support portion 304 of the serially connected lifting module 200, so that the length extension directions of the third support portion 303 and the fourth support portion 304 are parallel to each other and perpendicular to the length extension direction of the serially connected lifting module 200. Retract the telescopic male connectors 307 in the third support portion 303 and the fourth support portion 304 into their respective telescopic female connectors 306.

[0053] Subsequently, the support angles of the first support portion 301 and the second support portion 302 of another serially connected lifting module 200 are adjusted so that the length extension directions of the first support portion 301 and the second support portion 302 are parallel to each other and perpendicular to the length extension direction of the serially connected lifting module 200. The telescopic male connectors 307 in the first support portion 301 and the second support portion 302 are retracted into the interiors of their respective telescopic female connectors 306.

[0054] Then, the telescopic female head 306 in the third supporting part 303 of the last serially connected lifting module 200 is aligned with the central axis of the telescopic female head 306 of the first supporting part 301 of the current serially connected lifting module 200; the telescopic female head 306 in the fourth supporting part 304 of the last serially connected lifting module 200 is aligned with the central axis of the telescopic female head 306 of the second supporting part 302 of the current serially connected lifting module 200. The telescopic male head 307 of the first supporting part 301 of the current serially connected lifting module 200 is extended into the inner cavity of the telescopic female head 306 of the third supporting part 303 of the last serially connected lifting module 200; the telescopic male head 307 of the second supporting part 302 of the current serially connected lifting module 200 is extended into the inner cavity of the telescopic female head 306 of the fourth supporting part 304 of the last serially connected lifting module 200.

[0055] Continue to adjust the support angles of the third support portion 303 and the fourth support portion 304 in the cascaded lifting module 200. For example, the angle between the length extension direction of the third support portion 303 and the length extension direction of the cascaded lifting module 200 is 45°, the angle between the length extension direction of the fourth support portion 304 and the length extension direction of the cascaded lifting module 200 is 45°, and the angle between the length extension direction of the third support portion 303 and the length extension direction of the fourth support portion 304 is 90°. Finally, extend the telescopic support legs 308 in the two cascaded lifting modules 200 until they are stably supported on the ground.

[0056] According to the above described embodiments, when multiple lifting modules 200 that can be connected in series are working together, part of the telescopic male head 307 of the lifting module 200 can be extended into the telescopic female head 306 of the lifting module 200 on the adjacent side. Therefore, on the one hand, the support strength of the lifting module 200 can be enhanced, thereby improving the safety of disaster relief work. On the other hand, compared with the prior art in which multiple firefighting machines work at the same time, the lifting module 200 that can be connected in series can expand the scope of disaster relief work and improve its flexibility and versatility of use.

[0057] It should be noted here that the power source for driving the telescopic female head 306, the telescopic support leg 308 and the telescopic male head 307 to perform telescopic movements includes a hydraulic system. For example, a hydraulic cylinder can be used to drive the telescopic female head 306, the telescopic male head 307 and the telescopic support leg 308 to perform telescopic movements.

[0058] In another embodiment of the present invention, the first support portion 301, the second support portion 302, the third support portion 303 and the fourth support portion 304 have the same structure, and all include a connecting arm 305 and a telescopic support leg 308. The connecting arm 305 is rotatably connected to the frame 202. The telescopic support leg 308 is connected to the connecting arm 305 and can be telescopic and supported on the ground.

[0059] Furthermore, in one embodiment of the present invention, the series assembly includes a swing arm rotatably connected to the frame 202 and a slot portion adapted to the swing arm, and the swing arm of each serially connected lifting module 200 can be swung and clamped in the slot portion of the adjacent serially connected lifting module 200, so that multiple serially connected lifting modules 200 are connected in series with each other.

[0060] When multiple lifting modules 200 that can be connected in series need to be connected in series, the swing arm of each lifting module 200 that can be connected in series can be swung and clamped in the clamping groove of the adjacent lifting module 200, so that multiple lifting modules 200 that can be connected in series can work together.

[0061] In one embodiment of the present invention, the lifting assembly includes a lifting arm 400. A water channel for getting on a vehicle and a fire monitor are arranged in the lifting arm 400. For example, the lifting arm 400 can be extended and retracted and the angle can be adjusted by using an oil cylinder as a driving force.

[0062] Further, in one embodiment of the present invention, an electrical control system 203 is provided on the vehicle frame 202. The electrical control system 203 can control the working state of the cascade-connected lifting module 200. In addition, the cascade-connected lifting module 200 is provided with a wireless control module. The wireless control module can remotely and wirelessly control the working state of the cascade-connected lifting module 200.

[0063] Specifically, if Figures 1 to 5As shown, an electrical control system 203 is provided inside the vehicle frame 202. The lifting assembly includes a lifting arm 400. The lifting arm 400 is provided with a water channel for loading the vehicle and a fire monitor. The electrical control system 203 can control the working state of the lifting module 200 that can be connected in series. For example, the electrical control system 203 can control the walking device 201 of the lifting module 200 that can be connected in series. The electrical control system 203 can also control the support angle and telescopic length of the support assembly 300 in the lifting module 200 that can be connected in series. At the same time, the electrical control module 203 can also control the working state of the water channel for loading the vehicle and the fire monitor on the lifting arm 400.

[0064] In addition, the tandem lifting module 200 is provided with a wireless control module. The wireless control module can remotely and wirelessly control the working state of the tandem lifting module 200. In other words, the staff can remotely control the walking device 201 of the tandem lifting module 200, the support angle and telescopic length of the support assembly 300, and the working state of the vehicle waterway and fire monitor on the lifting arm 400, etc.

[0065] It should be understood that the above embodiment is only an exemplary embodiment of the present invention and does not constitute any limitation to the present invention. That is, the control scope of the electrical control system 203 and the wireless control module is not limited to the scope described in the above embodiment.

[0066] It can be seen from the above described embodiments that the lifting module 200 has a remote control function, and firefighters can remotely control the lifting module 200 to perform disaster relief work, thereby effectively ensuring the personal safety of firefighters.

[0067] Meanwhile, in one embodiment of the present invention, a water hose inlet is also provided on the frame 202 of the serially connectable lifting module 200. The other end of the water hose connected to the water hose inlet is connected to other water tank fire fighting operation machinery or a fire hydrant water source interface.

[0068] The embodiment of the second aspect of the present invention provides a fire fighting machine, comprising: a transport device 100 and a lifting module 200 that can be connected in series as described above.

[0069] The transport device 100 and the serially connectable lifting module 200 are independently arranged. The serially connectable lifting module 200 can move and park in the transport device 100 and be transported to a target location by the transport device 100.

[0070] Through this structural setting, the transport device 100 and the lifting module 200 are independently set. The lifting module 200 can independently move into the transport device 100. After the transport device 100 transports the lifting module 200 to the target location, the transport device 100 evacuates the site, and the lifting module 200 can independently move to the working point. As a result, the lifting module 200 does not need to be based on the transport device 100 for disaster relief work, and its footprint is reduced. At the same time, the passability and flexibility of the lifting module 200 are also greatly improved.

[0071] Existing high-rise fire fighting machines, such as high-rise jet fire trucks, generally need to rely on larger and longer chassis and supports to achieve a large operating range, which requires a large deployment space and occupies a large area. However, existing fire fighting machines cannot meet the requirements of large-scale operations in narrow spaces or when multiple fire fighting machines need to work together to extinguish fires efficiently.

[0072] In the fire fighting machine provided by the present invention, by combining the transport device 100 and the lifting module 200 that can be connected in series, long-distance rapid transportation can be achieved through the transport device 100. The lifting module 200 that can be connected in series does not need long-distance maneuverability, and it can be designed as a smaller structure, and its ability to pass through and operate in narrow spaces is stronger. Through the serial cooperative operation of multiple lifting modules 200 that can be connected in series, the support range and chassis stability of the fire fighting machine can be increased, thereby achieving a wider range of rescue operations.

[0073] In one embodiment of the present invention, the transport device 100 includes a box 101. The tandem lifting modules 200 can travel and park inside the box 101. In addition, a flip pedal 102 is provided at the rear of the box 101 for the tandem lifting modules 200 to travel. A locking device 103 is provided inside the box 101 to prevent the tandem lifting modules 200 from shaking.

[0074] Furthermore, in one embodiment of the present invention, the fire fighting machine includes at least one lifting module 200 that can be connected in series.

[0075] For example, Figure 1As shown, two lifting modules 200 that can be connected in series are parked in the transport device 100. After the transport device 100 transports the two lifting modules 200 that can be connected in series to the target location, the lifting modules 200 that can be connected in series can walk to the disaster relief site to perform rescue work according to actual disaster relief needs. The two lifting modules 200 can perform disaster relief work independently. At this time, the support angles of the first support part 301, the second support part 302, the third support part 303 and the fourth support part 304 in the two lifting modules 200 are adjusted respectively. When each lifting module 200 is working independently, the telescopic male head 307 in the support assembly 300 can be retracted to the inside of each telescopic female head 306 to reduce the floor space.

[0076] In one embodiment of the present invention, the fire fighting machine includes a plurality of lifting modules 200 that can be connected in series.

[0077] The telescopic male connector 307 of each serially connected lifting module 200 can be inserted into the telescopic female connector 306 of an adjacent serially connected lifting module 200 to achieve serial connection of multiple serially connected lifting modules 200 .

[0078] For example, Figure 1 As shown, the fire fighting machine includes a transport device 100 and two independent lifting modules 200. The transport device 100 includes a box 101. A flip pedal 102 is provided at the rear of the box 101. A locking device 103 is provided inside the box 101. Both independent lifting modules 200 are provided with a walking device 201.

[0079] When the lifting module 200 needs to enter the compartment 101, the flip pedal 102 is flipped to a state where it can overlap with the ground and the rear of the compartment 101, and two independent lifting modules 200 move into the compartment 101 in sequence. Subsequently, the locking device 103 inside the compartment 101 is flipped upward and clamped on the walking device 201 of each lifting module 200 to prevent each lifting module 200 from moving in the compartment 101. Finally, the flip pedal 102 is retracted to the rear of the compartment 101 and away from the ground. The transport device 100 transports the lifting module 200 to the vicinity of the target location.

[0080] When the lifting module 200 needs to evacuate the compartment 101, first unlock the locking device 103 inside the compartment 101. Then, flip the flip pedal 102 again to a state where it can overlap with the ground and the rear of the compartment 101, and the two independent lifting modules 200 move to the outside of the compartment 101 in turn. The lifting module 200 moves independently to the disaster relief site to carry out rescue work. The transport device 100 evacuates the site.

[0081] According to the above described embodiments, by providing a flip pedal 102 at the rear of the compartment 101, it is convenient for the lifting module 200 to move into the compartment 101. A locking device 103 is provided in the compartment 101, which can effectively ensure that the lifting module 200 does not slide during transportation, thereby improving the safety of the walking and transportation of the fire fighting operation machinery.
