Description

Technical Field

[0001] The invention relates to the technical field of fire fighting equipment, and in particular to a fire fighting truck for quickly laying water hoses. Background Art

[0002] As a special vehicle specially used for fighting fires and performing emergency rescue tasks, fire trucks are equipped with a variety of firefighting equipment and tools, which can reach the fire scene in the first time and take effective measures to extinguish the fire and rescue. In the process of fire fighting, the rapid laying of fire hoses is one of the key factors to ensure the efficiency of fire fighting. Traditional fire trucks are usually equipped with a winch device for winding and unfolding fire hoses to increase the laying speed of the hoses, shorten the fire fighting time, and thus improve the fire fighting efficiency.

[0003] However, the winch device in the prior art still has some shortcomings in actual use. Specifically, when the fire truck arrives at the fire scene, the firefighters still need to take out the end of the fire hose from the car and unfold the hose through the winch device. Although the winch device can accelerate the unfolding of the hose to a certain extent, it still takes a certain amount of time for the hose wound on the winch device to be fully unfolded. This process not only increases the operational burden of the firefighters, but may also cause delays in laying the hose, thereby affecting the efficiency of fire fighting;

The other end of the water outlet pipe 22 is connected to the other end of the rotating joint 43. The outer wall of the rotating shaft 42 is fixedly installed with a drain pipe 422 connected to the inside of the water passage cavity 421, and the end of the drain pipe 422 is detachably connected with a fire hose 423. The bracket 41 is installed with a driving mechanism 44 for driving the rotating shaft 42 to rotate. When in use, the high-pressure water pump 21 is controlled to work to pump out the water source stored in the water storage tank 12 through the water inlet pipe, and then transport it to the water passage cavity 421 through the water outlet pipe 22, and then transport it to the fire hose 423 through the drain pipe 422, and then discharge it through the other end of the fire hose 423 to perform fire extinguishing operations;

The hinged plate 632 is installed with a length measuring component 8, which is used to measure the length of the fire hose 423 passing through the hinged plate 632 and the lower clamping plate 61. When in use, the connecting block 323 can be moved closer to or farther away from the displacement block 321 along the two telescopic rods 322 through the electric cylinder 324, thereby adjusting the position of the upper clamping plate 63 and the lower clamping plate 61, thereby adjusting the position between the fire hose 423 and the lower clamping plate 61, thereby effectively ensuring that the fire hose 423 is located between the connecting plate 631 and the lower clamping plate 61 or between the hinge plate 632 and the lower clamping plate 61; through the length measuring component 8, the length of the fire hose 423 passing through the hinge plate 632 and the lower clamping plate 61 is measured, thereby achieving the effect of measuring the length of the fire hose 423 wound around the outside of the rotating shaft 42, which is conducive to controlling the motor 362 to drive the clamping mechanism 6 to wind and reel the fire hose 423.

[0055] In this embodiment, the length measuring assembly 8 includes a measuring roller 81, an infrared signal transmitter 82 and an infrared signal receiver 83.

When the infrared signal receiver 83 faces the infrared signal transmitter 82, it receives the infrared signal emitted by the infrared signal transmitter 82, and it can be known that the measuring roller 81 rotates one circle in the mounting hole 6321. By measuring the circumference of the outer wall of the measuring roller 81, it can be known that the moving length of the fire hose 423 from the measuring roller 81 to the lower clamping plate 61 can be obtained, so as to achieve the effect of measuring the length of the fire hose 423 passing between the hinge plate 632 and the lower clamping plate 61.
