[0063] Optionally, a through hole 11 is provided on the fork knife body 10 at a position corresponding to the spray port 22 , and the through hole 11 is used to spray the fire extinguishing medium sprayed from the spray port 22 toward the target object.

[0064] Specifically, the spray pipe 21 is fixedly connected to the second surface 102, and the spray port 22 is arranged on the spray pipe 21. At the position corresponding to the spray port 22, a through hole 11 is arranged on the fork knife body 10. On the one hand, when the fork knife body 10 contacts the target object, the heat transferred by the target object after contacting the fork knife body 10 can be released through the through hole 11. On the other hand, the fire extinguishing medium sprayed from the spray port 22 can be sprayed from the contact part of the fork knife and the target object to the fire place through the through hole 11, which further strengthens the heat dissipation of the through hole 11 and avoids overheating of the contact surface between the accident vehicle and the fork knife body 10, causing damage to the fork knife body 10. The number of through holes 11 can be 2, 3, 4, etc. The number of through holes 11 can be specifically set according to actual conditions, and the embodiment of the present application does not make specific restrictions.

The internal fire medium in the spray port 22 on the main flow pipe 211 and the branch pipe 212 is sprayed toward the target object through the through hole 11. The fire extinguishing medium can be sprayed toward the target object through the diversion pipe 212 in multiple directions along the fork knife body 10, further improving the fire extinguishing effect.

[0067] As a preferred solution, high-pressure nozzles can be installed on the spray ports 22 of the main pipe 211 and multiple branch pipes 212. The fire extinguishing medium can be sprayed toward the target object through the high-pressure nozzles. The fire extinguishing medium can be sprayed toward the target object more evenly and quickly, thereby improving the fire extinguishing efficiency.

In actual applications, the spray pipes 21 are respectively fixedly connected to the two third surfaces 103 of the fork knife body 10, so that the fire extinguishing medium can be sprayed toward the target object from both sides of the fork knife body 10, thereby further improving the fire extinguishing effect of spraying the target object from the side.

[0073] In the second aspect, the embodiment of the present application further provides a forklift, specifically, the forklift is mainly used to transfer vehicles in danger when a vehicle explosion and fire occurs. It is more applicable to the transfer of vehicles in danger after a new energy vehicle fire and explosion accident occurs.

[0074] Reference Figure 6-Figure 11 The forklift comprises: a vehicle body 2; a storage box 3, wherein the storage box 3 is arranged on the vehicle body 2 to store the fire extinguishing medium; and a fork knife 1 as described in any of the above embodiments; the fork knife 1 is connected to the vehicle body 2, and a spray mechanism on the fork knife is connected to the storage box 3.

[0075] Specifically, the vehicle body 2 carries a storage box 3 and the fork knife described in any of the above embodiments. The storage box 3 is arranged at a position near the fork knife body 10 of the vehicle body 2. The storage box 3 stores a fire extinguishing medium and is connected to the spray mechanism 20 on the fork knife, so that the fire extinguishing medium in the storage box 3 can be sprayed on the target object through the spray mechanism 20. The storage box 3 as a whole can be made of a steel-aluminum composite plate made of explosion-proof plate 7. The composite plate is made of steel plate and aluminum plate through a composite process, has good mechanical properties and high temperature resistance, is suitable for explosive hazardous environments, and can play an explosion-proof protection role when the target object suddenly explodes, preventing the high temperature and strong impact generated by the explosion from damaging the unmanned transport forklift body 2. The fire extinguishing medium can be a substance such as water that can be used for fire extinguishing and cooling.

[0076] The forklift also includes a vertical frame assembly 4 and a horizontal frame 5; the vertical frame assembly 4 is movably connected to the body 2, and the vertical frame assembly 4 can be movably set on the body 2; the horizontal frame 5 is fixedly connected to the vertical frame assembly 4, and the fork knife is connected to the horizontal frame 5; the horizontal frame 5 is provided with a first connecting rod 51 placed along the horizontal direction Y, the fork knife is movably connected to the first connecting rod 51, and the fork knife 1 is movably set on the first connecting rod 51 to drive the fork knife 1 to move along the horizontal direction Y.

[0077] Specifically, the vertical frame assembly 4 includes an external vertical frame 40 and an internal vertical frame 41. The external vertical frame 40 is connected to the vehicle body 2. A movable pulley 401 is provided on the external vertical frame 40. The movable pulley 401 is connected to a chain. A slide rail is provided on the internal vertical frame 41. The movable pulley 401 is located in the slide rail of the internal vertical frame 41. The chain is connected to the internal vertical frame 41. Under the action of the movable pulley 401, the chain pulls the internal vertical frame 41 to move in the vertical direction Z. A fixed structure 410 is provided on the internal vertical frame 41. A slot structure 53 is provided on the cross frame 5. The slot structure is connected to the fixed structure 410, so that the cross frame 5 is fixedly connected to the internal vertical frame 41. A first connecting rod 51 is provided on the cross frame 5. There may be two forks 1. The two forks 1 are respectively connected to the first connecting rod 51 on the cross frame 5.

[0078] In actual application, the fork knife body 10 is movably connected to the horizontally placed first connecting rod 51 on the cross frame 5, and the fork knife body 10 can move horizontally along the first connecting rod 51, which can drive the fork knife body 10 to move in the horizontal direction Y, thereby avoiding driving the entire cross frame 5 to move in the horizontal direction Y, thereby reducing the weight of the fork knife moving in the horizontal direction Y and improving the stability of the fork knife horizontal movement.

[0079] Optionally, the external vertical frame 40 can be connected to the vehicle body 2 through a telescopic device 6, and the telescopic device 6 can be extended or retracted. During the forklift transportation process, the telescopic device 6 is extended, and the vertical external vertical frame 40 can be tilted forward, so that the fork knife changes from an inclined state to a horizontal state, aligns with the side of the target object to be transported, and inserts the fork knife into the bottom space of the target object to be transported. When the telescopic device 6 is retracted, the external vertical frame 40 is pulled backward to restore the fork knife to an inclined state, so that the tip of the fork knife contacts the bottom of the target object to be transported to form a force support point, thereby preventing the accident vehicle from moving forward and falling due to bumps during transportation. The telescopic device 6 in the embodiment of the present application can adopt a hydraulic telescopic device 6, etc., and its specific structure is the prior art, and the embodiment of the present application does not make specific limitations on this.

[0080] Optionally, transfer boxes 402 are fixedly installed on both sides of the external vertical frame 40, and the top of the transfer box 402 is connected to the storage box 3 by a pipe, and the bottom of the transfer box 402 is connected to the spray mechanism 20 on the fork knife by a hose. The transfer box 402 is used to transfer the fire extinguishing medium in the storage box 3 to the spray mechanism 20. By setting up the transfer box 402, it is possible to avoid the problem of excessive length of the pipeline caused by the direct connection of the pipeline to the storage box 3, which may make the spraying process of the spray mechanism 20 smooth. The transfer box 402 and the spray mechanism 20 are connected by a hose, so that the spray mechanism 20 is not affected when the vertical frame assembly 4 moves vertically.

[0081] Optionally, an insert 52 is further provided on the first connecting rod 51, the insert 52 is sleeved on the first connecting rod 51, and the insert 52 is movably provided on the first connecting rod 51; a connecting hole 12 is provided on the fork knife 1; a protrusion 521 is provided on the insert 52, and the protrusion 521 is embedded in the connecting hole 12.

[0082] Specifically, the horizontal frame 5 is provided with a first connecting rod 51 and a second connecting rod 50 at intervals. The first connecting rod 51 is provided with a horizontally movable insert 52. The protrusion 521 on the insert 52 is embedded in the connection hole 12 on the fork knife 1, so that the fork knife 1 can be driven to move in the horizontal direction by adjusting the position of the insert 52, thereby adjusting the horizontal distance between the two fork knives 1 and the horizontal position of the two fork knives 1. In addition, since the interlocking connection is a relatively simple connection method, the connection method between the insert 52 and the fork knife 1 is simpler by inserting the protrusion 521 on the insert 52 in the connection hole 12. The second connecting rod 50 is a cylindrical connecting rod. The two fork knives 1 are sleeved on the second connecting rod 50. On the one hand, the reliability of the connection between the fork knife 1 and the horizontal frame 5 can be improved. On the other hand, during the horizontal movement, the friction force is generated between the two fork knives 1 and the second connecting rod 50, and the friction force can provide resistance for the horizontal movement of the fork knife 1.

[0083] Optionally, the forklift may further include an explosion-proof plate 7 , which is arranged on a side of the vehicle body 2 close to the fork knife 1 .

[0084] In practical applications, the explosion-proof plate 7 can protect the vehicle body 2 when the dangerous vehicle explodes and catches fire during the process of transferring the dangerous vehicle by forklift, and prevent the vehicle body 2 from being damaged by the high temperature and strong impact caused by the explosion. Exemplarily, the explosion-proof plate 7 can be composed of a steel-aluminum composite plate made of steel and aluminum through a composite process, which has good mechanical properties and high temperature resistance, is suitable for explosion-hazardous environments, and can play an explosion-proof protection role when the accident vehicle suddenly explodes.

[0085] In one embodiment, the forklift has an unmanned control function, which can be realized by remote control. Fig.12 , showing a schematic diagram of a forklift remote control system provided in an embodiment of the present application.

[0086] Specifically, the vehicle body 2 is also equipped with an unmanned intelligent control box 8, which is arranged at the head position of the vehicle body 2. The principle of remote control is: the command signal sent by the remote control is converted into a wireless signal through wireless communication technology and transmitted to the receiver in the unmanned intelligent control box 8 through radio waves, and then the wireless signal is converted into a control signal, and the remote control of the forklift is realized through the control signal.

[0087] like Fig.12 As shown, the specific implementation process is: the operator operates the remote control to issue a control command, the signal transmitter in the remote control transmits a radio wave with a command signal, and the signal receiver in the unmanned intelligent control box 8 receives the transmitted radio wave and converts it into a control signal. After the control signal is processed by the circuit of the central controller, it is output to the vehicle controller ECU (Electronic Control Unit) via the CAN (Controller Area Network) bus, and then output to the drive unit ECU, the transport unit ECU and the fire unit ECU according to the command action issued. Each unit ECU controls each system or mechanism to act according to the command. The main remote control functions include the driving function of the transfer vehicle, the lateral and vertical movement of the transport unit, and the remote control of the sprinkler. In order to increase the stability of the remote control, frequency hopping technology is used to change the frequency of the radio wave to improve the safety and anti-interference ability of the operating system. There is a screen on the remote control panel, and the external vertical frame 40 is connected to a high-definition camera 403, which monitors the real-time picture through the high-definition camera 403 for remote operation.

[0088] Specifically, the drive unit ECU is used to control the power system and steering system of the forklift. The drive unit ECU is electrically connected to the power system and the steering system. The power system includes the engine, drive wheels and other components of the forklift that enable the forklift to move. The steering system includes components that enable the forklift to perform steering operations. The specific components included in the power system and the steering system can be specifically set according to actual conditions, and the embodiments of the present application do not specifically limit this. The transport unit ECU is used to control the forward tilting mechanism, lifting mechanism and transverse movement mechanism of the forklift. The transport unit ECU is electrically connected to the forward tilting mechanism, lifting mechanism and transverse movement mechanism. The forward tilting mechanism includes: a telescopic device 6 and an external vertical frame 40, and the lifting mechanism includes: an external vertical frame 40 and an internal vertical frame 41. The transverse movement mechanism includes: a horizontal frame 5 and a fork knife 1. The fire unit ECU is used to control the spraying mechanism 20 and the supplementary mechanism. The spraying mechanism 20 includes: a spray pipe 21 and a spray port 22. The supplementary mechanism includes: a storage box 3 and a transfer box 402.

[0089] The specific control process is as follows: the drive unit ECU controls the power system and the steering system to drive the forklift to the designated location, the transport unit ECU controls the telescopic device 6 to extend and retract, so that the fork knife 1 changes from an inclined state to a horizontal state, and then controls the lifting mechanism to lower the fork knife 1 to the lowest position, the drive unit ECU controls the power system and the steering system to drive the forklift to move until the fork knife 1 is inserted into the bottom of the object to be transported, and then controls the lifting mechanism to move the fork knife 1 upward until the object to be transferred is off the ground, and then controls the power system and the steering system to drive the forklift to transport the target object to the designated location, and then controls the lifting mechanism to lower the fork knife 1 until the vehicle to be transported stably touches the ground, and then controls the forklift to reverse to complete the transport operation. If the designated location has a certain height, the lifting mechanism can be controlled to move the fork knife 1 upward to lift the object to be transported to the designated height, and then the forklift can be controlled to move forward, and then the fork knife 1 can be lowered and reversed to complete the transport operation.

[0090] During the transport process, if there is smoke or fire at the bottom of the object to be transported, the fire unit ECU controls the spray mechanism 20 to spray, and the fire extinguishing coolant is transported from the transfer box 402 to the spray port 22 through the spray pipe 21 and then sprayed out to cool the bottom area of ​​the vehicle to be transported. When the storage of the transfer box 402 is insufficient, the fire unit ECU controls the storage box 3 to add the fire extinguishing coolant to the transfer box 402, and keeps the spray port 22 spraying for cooling.
