[0035] During the transfer process of the vehicles currently used to transfer new energy vehicles, the fire further spread and may also pose a danger to the operators of the transfer vehicles.

[0036] The invention provides a forklift.

[0037] Please refer to Figure n. In one embodiment of the present invention, the forklift 100 includes a body 1, a water tank 2, a pipe assembly 3, a nozzle 4 and a drive assembly 5; the body 1 includes a fork 11; the water tank 2 is installed on the body 1 and is used to store fire extinguishing agent; the pipe assembly 3 has a water inlet and a water outlet, the water inlet is connected to the water tank 2, and the water outlet is arranged below the fork 11; the nozzle 4 is hinged to the pipe assembly 3 and connected to the water outlet, and the nozzle 4 and the fork 11 are staggered in the left and right directions; the drive assembly 5 is drivingly connected to the nozzle 4 to at least drive the nozzle 4 to rotate along the axis in the up and down directions.

[0038] The technical solution of the present invention stores fire extinguishing agent in a water tank 2, and sprays the fire extinguishing agent from a nozzle 4 at the water inlet through a pipe assembly 3. Since the fork plate is in contact with the bottom of the vehicle, the pipe assembly 3 is arranged below the fork plate and then extends with the fork plate. On the one hand, the fork plate can resist the fire for the pipe assembly 3, and on the other hand, the farther the water outlet is from the fork plate in the up and down directions, the wider the range of the fire extinguishing agent sprayed by the nozzle 4. In order to prevent the fork plate from blocking the fire extinguishing agent from spraying toward the bottom of the vehicle, the nozzle 4 and the fork 11 are staggered in the left and right directions. When the fork 11 forks the burning vehicle, the nozzle 4 arranged at the lower side of the fork 11 sprays the fire extinguishing agent toward the bottom of the vehicle. The opening position of the nozzle 4 is adjusted through the drive assembly 5, so that the fire extinguishing agent is sprayed toward the fire source, so as to achieve the technical effect of suppressing the fire when transporting the vehicle.

[0039] In order to adjust the angle of the nozzle 4 and to enable the nozzle 4 to rotate along the vertical axis, in one embodiment, the specific structure of the driving assembly 5 is as follows: the driving assembly 5 also includes: a mounting plate 51, a motor 52, a first connecting member 53 and a second connecting member 54; the mounting plate 51 extends in the left-right direction and is fixedly arranged on one side of the pipeline assembly 3, and the mounting plate 51 provides a mounting base for the installation of the motor 52; the motor 52 is fixedly installed on the mounting plate 51; one end of the first connecting member 53 is fixedly connected to the end of the motor 52, and the rotation of the motor 52 drives the other end of the first connecting member 53 to rotate around the vertical axis; one end of the second connecting member 54 is fixedly arranged at the other end of the first connecting member 53, and the other end is connected to the nozzle 4. Therefore, the rotation of the first connecting member 53 drives the second connecting member 54 and the nozzle 4 to rotate, wherein, if the nozzle 4 can only rotate along the vertical axis, then the nozzle 4 is tilted relative to the vertical direction, otherwise the rotation of the nozzle 4 cannot change the direction.

[0040] Since the nozzle 4 is only rotated along the vertical axis, the adjustment of the direction of the nozzle 4 is limited to a certain extent. Therefore, in one embodiment, the second connecting member 54 has a movable stroke that can be extended and retracted along the direction in which it extends, and the second connecting member 54 includes an electric cylinder 541. Through the extension and retraction of the electric cylinder 541, the inclination angle of the nozzle 4 relative to the vertical direction can be adjusted, so that the nozzle 4 has a larger adjustment range.

[0041] Since the upper side of the mounting plate 51 is opposite to the bottom of the vehicle, in order to protect the motor 52 and the main body 5411 of the electric cylinder 541, the motor 52 and the main body 5411 of the electric cylinder 541 need to be installed below the mounting plate 51, so that the mounting plate 51 can protect the motor 52 and the main body 5411 of the electric cylinder 541 and isolate the flame or falling objects. Specifically, the motor 52 is arranged below the first connecting member 53, the connecting shaft of the motor 52 passes through the mounting plate 51, extends to the upper side of the mounting plate 51, and is connected to the first connecting member 53, the mounting plate 51 is provided with an arc groove 511 corresponding to the active path of the end of the first connecting member 53 away from the motor 52, the electric cylinder 541 includes a main body 5411 and a telescopic rod 5412 installed on the main body 5411, the first connecting part is partially passed through the arc groove 511 to be connected to the main body 5411, and the telescopic rod 5412 passes through the arc groove 511 to be connected to the rotating shaft 6 of the nozzle 4. The telescopic rod 5412 and the first connecting member 53 on the upper side of the mounting plate 51 as well as the mounting plate 51 are all made of metal parts, which are resistant to high temperatures and not easily deformed.

[0042] In order to effectively control the fire when transporting the vehicle, the maximum range of the fire extinguishing agent needs to be large enough to be able to spray all parts of the bottom of the vehicle. The nozzles 4 are arranged in a plurality at intervals along the front and rear directions, and the corresponding drive components 5 are also arranged in plurality, which are respectively driven and connected to the plurality of nozzles 4.

[0043] In order to make the fire extinguishing agent sprayed from the nozzle 4 diffuse and obtain a larger fire extinguishing area, the nozzle 4 has multiple water outlet pipes 41 and a central axis. The angle between the extension direction of the water outlet pipe 41 and the central axis is proportional to the distance from the extension direction of the water outlet pipe 41 to the central axis.

[0044] Since the best fire extinguishing effect can be obtained by treating the fire source, but the positions of batteries of different vehicles are different, it is necessary to know the position of the fire source. In one embodiment, the forklift 100 further includes a sensor and a control device. The infrared sensor is installed on the vehicle body 1 and is arranged in the area above the fork 11. The control device is electrically connected to the infrared sensor and the drive assembly 5 respectively. The infrared sensor is used to find the position of the fire source, and the control device drives the drive assembly 5 to deflect the nozzle 4 toward the position of the fire source.

[0045] Since the pipeline of the pipeline assembly 3 located in front of the mast 12 may be exposed to high temperature, the pipeline located in front of the mast 12 is set as a metal pipe 31, and with the rise and fall of the fork 11, the pipeline assembly 3 cannot be set as a metal pipe 31 as a whole, and the pipeline assembly 3 includes: a metal pipe 31 and a hose 32, the metal pipe 31 is set below the fork 11, the water outlet is set in the metal pipe 31; the hose 32 connects the metal pipe 31 and the water tank 2. Among them, the metal pipe 31 is in a position that may be exposed to high temperature, and the hose 32 is set in a reasonable temperature range, and can ensure that the metal pipe 31 rises and falls with the fork 11.

[0046] Since the fork 11 needs to rise or fall, the overall length of the hose 32 needs to be longer. When the fork 11 falls to the lowest point, the excess length of the hose 32 needs to be stored to prevent the hose 32 from falling or interfering with other parts. In one embodiment, the forklift 100 also includes: a rotating shaft 6 and a torsion spring; the rotating shaft 6 is rotatably mounted on the vehicle body 1 along its axial direction; the torsion spring is arranged between the rotating shaft 6 and the vehicle body 1, and two torsion springs are arranged at both ends of the rotating shaft 6 respectively; the hose 32 is wound around the rotating shaft 6, one end of the hose 32 extends forward to communicate with the metal pipe 31, and the other end extends backward to communicate with the water tank 2. When the fork 11 goes up, the fork 11 drives one end of the hose 32 to move, overcomes the elastic force of the torsion spring, rotates the rotating shaft 6, and separates the hose 32 from the rotating shaft 6; when the fork 11 goes down, under the elastic force of the torsion spring, the rotating shaft 6 rotates in the opposite direction, so that the hose 32 is wound around the rotating shaft 6 for storage.

[0047] In order to ensure the safety of the forklift 100 operator, the forklift 100 further includes explosion-proof glass 7, the vehicle body 1 includes a gantry 12, the cargo fork 11 is slidably mounted on one side of the gantry 12, and the explosion-proof glass 7 is fixedly mounted on the other side of the gantry 12 opposite to the cargo fork 11. The explosion-proof glass 7 is used to separate the driver and the vehicle. The explosion-proof glass 7 can not only block the fragments generated during the explosion relative to the protective net, but also block the flame, and the explosion-proof glass 7 has a better observation field relative to the protective net.

[0048] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
