Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting facilities, and in particular to a fire hose auxiliary device. Background Art

[0002] At present, in the field of firefighting, in order to cope with various complex and special environments, firefighting robots have come into being. Although firefighting robots can replace manpower to enter dangerous and complex environments to extinguish fires, they also need to drag water hoses to operate. During normal firefighting operations, it is often necessary to move the water hoses in time according to the fire situation to complete the firefighting task in time. The weight of a water hose filled with water is very alarming. As its length increases, the overall weight of the water hose will gradually increase. The load capacity of the firefighting robot is limited. Coupled with the friction between the water hose and the ground, the firefighting robot moves slowly or even cannot move. Although the simple auxiliary moving devices on the market can assist the movement of the water hose, they often require additional locking structures to prevent the water hose from falling. The installation and use are troublesome, resulting in a waste of firefighting time. Summary of the Invention

[0027] Example

[0028] Combine Figure 1 and Figure 2 , this embodiment provides a fire hose auxiliary device, comprising: a base 10, a fixing assembly disposed on the base 10, and a supporting wheel assembly disposed under the base 10;

[0029] The base 10 is provided with a support column; the fixing assembly includes a trigger 20, a transmission rod 30 and an upper fixing member 40; one end of the trigger 20 is provided with a lower fixing member 21 for placing and supporting a water hose, and the other end is rotatably connected to the support column and is also provided with a first transmission member 22;

[0030] The transmission rod 30 is rotatably mounted on the support column and is placed above the trigger member 20. The transmission rod 30 is also provided with a second transmission member 31 corresponding to the first transmission member 22. One end of the upper fixing member 40 is connected to the transmission rod 30; the first transmission member 22 is configured to drive the second transmission member 31 when the lower fixing member 21 is acted upon by the gravity of the water hose, so that the transmission rod 30 rotates, and then drives the upper fixing member 40 to flip over to engage with the lower fixing member 21.

[0031] In this embodiment, the support column includes a first support column 11 and a second support column 12. The transmission rod 30 is arranged on the first support column 11, and the other end of the trigger member 20 is connected to the second support column 12. In other embodiments, there can be only one support column, and the other ends of the transmission rod 30 and the trigger member 20 are connected to the same support column.

[0032] In this embodiment, the supporting wheel assembly includes four universal casters 50, which are steel casters, not only having strong load-bearing capacity but also high temperature resistance. Of course, in other embodiments, the casters can also be non-metallic high-temperature resistant casters.

[0033] In this embodiment, if Figure 2 As shown, the first transmission member 22 is a first protrusion, and the second transmission member 31 is a second protrusion. When the lower fixing member 21 is acted upon by the gravity of the water hose, the first protrusion lifts the second protrusion, causing the transmission rod 30 to rotate, thereby driving the upper fixing member 40 to flip over to engage with the lower fixing member 21. In other embodiments, the first transmission member 22 and the second transmission member 31 can also be an integrated connecting rod, connected between the transmission rod 30 and the other end of the trigger member 20.

[0034] In this embodiment, the fire hose auxiliary device further includes a first elastic member 60, which is connected between the transmission rod 30 and the base 10 and is configured to drive the transmission rod 30 to rotate, so that the upper fixing member 40 flips away from the lower fixing member 21; Figure 2 The first elastic member 60 includes two springs, and the springs are made of silicon manganese spring steel. Two connecting columns 70 are provided on the base 10. The two springs are connected between the transmission rod 30 and the connecting column 70. When the lower fixing member 21 is free of water belt gravity, the transmission rod 30 rotates under the elastic force of the spring, thereby driving the upper fixing member 40 to flip and move away from the lower fixing member 21. In other embodiments, the spring can also be directly connected to the base 10, and the number of the springs can be more. The present invention does not make specific limitations here.

[0035] In this embodiment, if Figure 2As shown, the fire hose auxiliary device also includes a second elastic member 80, which is an elastic sheet. One end of the elastic sheet is connected to the bottom of the lower fixing member 21, and a supporting protrusion 13 corresponding to the position of the other end of the elastic sheet is provided on the base 10. The elastic sheet can assist the lower fixing member 21 in being in an untriggered state before use. Of course, in other embodiments, the second elastic member 80 can also be a spring directly provided between the lower fixing member 21 and the base 10.

[0036] The present invention assists the fire-fighting robot in dragging the water hose to perform operations by providing a base 10 with a supporting wheel assembly, thereby increasing its moving speed. At the same time, an upper fixing part 40 and a lower fixing part 21 are also provided on the base 10. The lower fixing part 21 will be triggered according to the weight of the water hose and drive the upper fixing part 40 to flip over, so that it is firmly fastened with the lower fixing part 21, fixing the water hose on the base 10, and preventing the water hose from slipping off the base 10 during movement. There is no need to fix the water hose through other locking devices. The water hose only needs to be placed on the lower fixing part 21, thereby improving efficiency.

[0037] Preferably, the fixing assembly further includes a magnet, which is arranged on the end surfaces of the two fixing members that are buckled with each other. The magnetism of the magnet can better assist the upper fixing member 40 and the lower fixing member 21 to be buckled.

[0038] Preferably, the fire hose auxiliary device further includes a housing 90 , which is connected to the base 10 and is used to cover the fixing assembly, leaving space for the upper fixing member 40 and the lower fixing member 21 to protect other transmission mechanisms.

[0039] Preferably, the upper fixing member 40 and the lower fixing member 21 are semicircular columnar structures, which can better fit the shape of the water hose.

[0040] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
