Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, in particular to a pneumatic fire fighting cannon. Background Art

[0002] Fire monitor is an important fire fighting equipment for long distance fire fighting. Fire monitor is divided into two series: fire water monitor and fire foam monitor. Among them, fire water monitor is a fire fighting equipment that sprays water to fight general solid materials at a long distance. It is widely used in petrochemical enterprises, storage tank areas, hangars, warehouses, port terminals and other places because of its wide pressure range, long range, light weight, small size, full functions and good fire extinguishing effect.

[0003] However, the existing fire cannon has some defects during use. The length of the existing fire cannon barrel is fixed and cannot be spliced ​​and used according to the use requirements. Moreover, the fire cannon with a longer barrel is not convenient to load and store after use. The existing fire cannon is not fixed firmly enough. When the barrel sprays a high-pressure water column, the strong recoil force will cause the barrel of the fire cannon to shake, resulting in the fire cannon being unable to accurately spray the high-pressure water column to the optimal fire extinguishing point, thereby reducing the fire extinguishing effect. The existing fire cannon cannot send the barrel forward. When there is an obstacle before the fire, the sprayed water column will be blocked by the obstacle, resulting in very little water reaching the fire point. At the same time, since the barrel of the fire cannon cannot be sent forward, in use, the fire cannon needs to be not too far away from the fire point, resulting in the firefighters operating the fire cannon being easily burned by the fire. The activity adjustment of the existing fire cannon all depends on the motor. The motor has limited power and is easily damaged before the fire, and is not reliable enough to use. Summary of the invention

[0004] In view of the problems in the prior art, the present invention provides a pneumatic fire monitor.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a pneumatic fire monitor, including a traveling component, a lifting component, a pipe connecting component, a fire extinguishing gun tube and a connecting component, wherein the lifting component is installed on the top of the traveling component, and the traveling component is arranged at the bottom of the fire monitor, so that the mobile transportation is more convenient, and in the process of fire fighting, the position can be easily moved, and the use is more convenient and flexible. By arranging the lifting component, the height of the fire monitor can be flexibly adjusted, so that the fire monitor can handle fires at higher places, improve the fire extinguishing range of the fire monitor, and make the application range of the fire monitor wider, the top of the lifting component is rotatably matched with a bogie, the top of the bogie is hinged with an adjustment frame, the top of the adjustment frame is horizontally fixed with a support bracket, and the support bracket is rotatably matched with a plurality of conveying bottom wheels, a fixed side plate is vertically welded on one side of the support bracket, the top of the fixed side plate is hinged with a limiting frame, and the top of the limiting frame is rotatably matched with a plurality of conveying pressure wheels, and the support bracket of the fire monitor is provided with a conveying bottom wheel, and a conveying drive motor drives one of the conveying bottom wheels to rotate, and the bottom of the limiting frame is rotatably matched with a plurality of conveying bottom wheels. The utility model is equipped with a conveying pressure wheel, which is driven by the conveying driving motor to rotate the conveying bottom wheel, so that the extension length of the combined fire-fighting gun tube can be adjusted. By adjusting the extension length of the fire-fighting gun tube, on the one hand, the combined fire-fighting gun tube used for spraying water in the fire-fighting gun can pass through the obstacle in front of the fire, and the water spray port can be delivered to the fire area, so that the high-pressure water column sprayed by the fire-fighting gun can reach the fire area behind the obstacle, so that the fire-fighting gun can extinguish the fire in the lane, the indoor of the building, etc., which is not easy to be sprayed with the high-pressure water column, and on the other hand, the fire-fighting gun can extinguish the fire in the lane, the indoor of the building, etc. The position of the water spray end can be flexibly changed according to the fire situation. On the other hand, multiple fire extinguishing gun tubes can be combined and transported with the conveying bottom wheel, so that the fire cannon can handle the fire from a long distance, avoiding the fire cannon vehicle body and the firefighters operating the fire cannon from being too close to the fire area, thereby avoiding the fire cannon being damaged by the fire and avoiding the firefighters being burned by the fire.

The rotating bottom wheel in the fire-fighting gun can rotate under the drive of the rotating drive motor. The rotating bottom wheel cooperates with the rotating pressure wheel to drive the combined fire-fighting gun barrel to rotate. After one section of the fire-fighting gun barrel is fixed by the supporting bracket and the limiting frame, the connecting pipe assembly drives the other section of the fire-fighting gun barrel to help firefighters assemble or disassemble the fire-fighting gun barrel, making the installation and use of the fire-fighting gun more labor-saving and the assembly speed of the fire-fighting gun faster.

On the other hand, the fire monitor can flexibly change the position of the water spray end according to the fire situation, making the fire extinguishing process more flexible and the fire extinguishing efficiency higher. On another hand, multiple fire extinguishing gun tubes can be combined and transported in conjunction with the conveying bottom wheel, so that the fire monitor can deal with the fire from a long distance, avoiding the fire monitor body and the firefighters operating the fire monitor from being too close to the fire area, thereby avoiding the fire monitor being burned by the fire and avoiding the firefighters being burned by the fire, thereby making the use of the fire monitor safer and more reliable.

[0022] (3) In the present invention, the rotating bottom wheel in the fire monitor can rotate under the drive of the rotating drive motor. The rotating bottom wheel cooperates with the rotating pressure wheel to drive the combined fire extinguishing gun barrel to rotate. After one section of the fire extinguishing gun barrel is fixed by the support bracket and the limit frame, the connecting pipe assembly drives the other section of the fire extinguishing gun barrel to help firefighters assemble or disassemble the fire extinguishing gun barrel, making the installation and use of the fire monitor more labor-saving, and making the assembly speed of the fire monitor faster, thereby improving the timeliness of fire handling.

[0023] (4) In the present invention, the steering drive motor is used to rotate the steering frame to adjust the direction of the fire cannon, and the cylinder two is used to drive and adjust the tilt angle of the fire cannon, so that the fire cannon is more flexible in handling fires, thereby making the fire cannon more effective in handling fires. The angle of the adjustment frame in the fire cannon is driven and adjusted by the cylinder two. The adjustment frame supports the combined fire extinguishing gun barrel. The cylinder two can provide more stable support, and in terms of angle adjustment, the cylinder two is more powerful than the motor drive. Similarly, the lifting top plate in the lifting assembly is subjected to greater force. The use of cylinder one in the lifting assembly for driving also provides stable support for the lifting and adjustment of the fire cannon. The fire cannon uses cylinders at key force points and key adjustment points, and uses pneumatics to make the fire cannon more reliable when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] When in use, first, the travel drive motor 103 drives the travel wheel 102 to rotate, and the travel assembly 1 is moved by rotating the travel wheel 102. The travel assembly 1 is moved to move the pneumatic fire monitor to the fire scene, and the cylinder 206 drives the push rod 207 to move. The push rod 207 pushes the two lowest scissor-type brackets 203 in the lifting assembly 2 to move, thereby driving all the scissor-type brackets 203 to move, so that the lifting top plate 202 moves up and down. By moving the lifting top plate 202 up and down, the height of the pneumatic fire monitor is adjusted, and the pneumatic fire monitor is adjusted to the corresponding height according to the location of the fire. The travel assembly 1 is set at the bottom of the fire monitor, which is more convenient to move and transport, and can be easily moved during the fire fighting process. The use is more convenient and flexible. Each traveling wheel 102 in the traveling component 1 is driven separately by a traveling drive motor 103, so that the power of the fire cannon to move is stronger and the movement in the complex terrain of the fire scene is more reliable. At the same time, the rotation speed of each traveling wheel 102 can be independently controlled, so that the steering of the fire cannon is more sensitive when traveling, thereby making the fire cannon more flexible to move in the complex terrain of the fire scene. By setting the lifting component 2, the height of the fire cannon can be flexibly adjusted, so that the fire cannon can handle fires at higher places, improve the fire extinguishing range of the fire cannon, and make the application range of the fire cannon wider. Then, the two threaded pipes 802 on the connecting component 8 are respectively matched with the ends of the two fire extinguishing cannon pipes 7, so that the two fire extinguishing cannons can be connected. The gun barrels 7 are combined together. Through this combination, several fire-fighting gun barrels 7 are connected together. The push rod 3 507 is driven by the cylinder 3 506. The push rod 3 507 drives the limit frame 504 to flip, so that the limit frame 504 is flipped down from just above the support bracket 5, and the combined fire-fighting gun barrel 7 is placed on the support bracket 5 and the two sets of rotating bottom wheels 602. The cylinder 3 506 is driven again to flip the limit frame 504 back to just above the support bracket 5. The position of the fire-fighting gun barrel 7 is limited by the limit frame 504 and the support bracket 5. At the same time, the screw rod 605 is driven to rotate by the lifting drive motor 606. By rotating the screw rod 605, the nut 608 moves along the screw rod 605, and the nut 608 drives the rotating pressure wheel 6 through the lifting block 607. 09 moves up and down, moves the rotating pressure wheel 609 downward, and further limits the position of the combined fire-fighting gun barrel 7 by rotating the pressure wheel 609 and the rotating bottom wheel 602. The inner walls of the ports at both ends of the fire-fighting gun barrel 7 of the fire-fighting gun are provided with internal threads 701, and two threaded tubes 802 are provided on the connecting component 8. The threaded tubes 802 at both ends of the connecting component 8 are threadedly connected to the ends of the two fire-fighting gun barrels 7, so that the two fire-fighting gun barrels 7 can be combined. By using multiple connecting components 8, multiple fire-fighting gun barrels 7 can be combined. In this way, on the one hand, by combining the fire-fighting gun barrels 7, the extension distance of the water spraying end of the fire-fighting gun is changed, so that the fire-fighting gun and the fire occurrence position can effectively deal with the fire in the case of short distance, medium distance and long distance.Thereby further improving the coverage of the fire cannon. On the other hand, a plurality of fire extinguishing gun tubes 7 are combined by the connecting assembly 8 and are easy to disassemble. After the fire cannon is used to extinguish the fire, the combined fire extinguishing gun tubes 7 can be disassembled into separate individuals, making it easier to load and store the fire cannon after use, thereby improving the convenience of carrying and using the fire cannon. By arranging a sealing gasket 803 on the connecting assembly 8, the sealing between the fire extinguishing gun tubes 7 connected by the connecting assembly 8 is made stronger, thereby ensuring the stability of the water pressure when the fire cannon is extinguishing the fire, thereby making the use of the fire cannon more reliable. The fire cannon uses the support bracket 5 and the limit frame 504 to cooperate with the rotating bottom wheel 602 and the rotating pressure wheel 609 to limit the combined fire extinguishing gun tube 7. The double limitation makes the combined fire cannon more reliable. The combined fire-fighting gun tube 7 is more secure in the fire-fighting gun, ensuring the smooth use of the fire-fighting gun, so that the fire-fighting gun can spray high-pressure water columns to the fire area more accurately, thereby improving the fire-fighting effect of the fire-fighting gun. A conveying bottom wheel 501 is arranged on the supporting bracket 5 of the fire-fighting gun, and a conveying drive motor 502 drives one of the conveying bottom wheels 501 to rotate. The bottom of the limit frame 504 is rotated with a conveying pressure wheel 505. Driven by the conveying drive motor 502, the conveying bottom wheel 501 is rotated to adjust the extension length of the combined fire-fighting gun tube 7. By adjusting the extension length of the fire-fighting gun tube 7, on the one hand, the combined fire-fighting gun tube 7 used for spraying water in the fire-fighting gun can pass through the obstacles in front of the fire, and the water spray port is delivered to the fire area, ensuring The high-pressure water column sprayed by the fire monitor can reach the fire area behind the obstacle, making it more convenient for the fire monitor to extinguish fires in lanes, building interiors and other areas that are not easy to be sprayed with high-pressure water columns, thereby making the application range of the fire monitor wider and making the fire extinguishing ability of the fire monitor stronger. On the other hand, the fire monitor can flexibly change the position of the water spray end according to the fire situation, making the fire extinguishing process more flexible and the fire extinguishing efficiency higher. On the other hand, multiple fire extinguishing gun tubes 7 can be combined and transported in conjunction with the conveying bottom wheel 501, so that the fire monitor can handle the fire from a long distance, avoiding the fire monitor vehicle body and the firefighters operating the fire monitor from being too close to the fire area, thereby avoiding the fire monitor being burned by the fire and avoiding the firefighters being burned by the fire, thereby making the fire monitor The use of the fire cannon is safer and more reliable. The rotating bottom wheel 602 in the fire cannon can rotate under the drive of the rotating drive motor 603. The rotating bottom wheel 602 cooperates with the rotating pressure wheel 609 to drive the combined fire extinguishing gun barrel 7 to rotate. After one section of the fire extinguishing gun barrel 7 is fixed by the support bracket 5 and the limit frame 504, the connecting pipe assembly 6 drives the other section of the fire extinguishing gun barrel 7 to help firefighters assemble or disassemble the fire extinguishing gun barrel 7, making the installation and use of the fire cannon more labor-saving, and making the assembly speed of the fire cannon faster, thereby improving the timeliness of fire handling. Finally, one end of the fire extinguishing gun barrel 7 on the support bracket 5 is connected to the high-pressure water pump through a hose, and a corresponding nozzle is installed at the water spraying end of the fire extinguishing gun barrel 7. The steering frame 3 is driven to rotate by the steering drive motor 301.Adjust the direction of the pneumatic fire monitor so that the fire extinguishing gun barrel 7 on the supporting bracket 5 faces the direction of the fire, and drive the push rod 2 402 to move through the cylinder 2 401, and the push rod 2 402 pushes the adjusting frame 4 to rotate, and the adjusting frame 4 drives the fire extinguishing gun barrel 7 to rotate through the supporting bracket 5, and adjusts the inclination angle of the fire extinguishing gun barrel 7. After adjusting the angle of the fire extinguishing gun barrel 7, the fire extinguishing gun barrel 7 can spray water pumped by the high-pressure water pump on the fire occurrence area to extinguish the fire in the area, and the steering frame 3 is rotated to adjust the direction of the fire monitor through the steering drive motor 301, and the cylinder 2 401 is used to drive and adjust the inclination angle of the fire monitor so that the fire monitor is in the direction of the fire. It is more flexible in handling fire, so that the fire monitor can handle fire more effectively. The angle of the adjustment frame 4 in the fire monitor is driven and adjusted by the cylinder 2 401. The adjustment frame 4 supports the combined fire extinguishing gun tube 7. The cylinder 2 401 can provide a more stable support, and in terms of angle adjustment, the cylinder 2 401 is more powerful than the motor drive. Similarly, the lifting top plate 202 in the lifting assembly 2 is subjected to greater force. The lifting assembly 2 uses the cylinder 1 206 for driving, which also provides stable support for the lifting and adjustment of the fire monitor. The fire monitor uses cylinders at key force points and key adjustment points, and uses pneumatics to make the fire monitor more reliable when in use.
