Description
Technical Field
[0001] The utility model relates to the technical field of fire safety, in particular to an underground emergency fire extinguishing cart. Background Art
[0002] Due to the nature of coal mines, fires are extremely common underground. To ensure safety underground, numerous firefighting devices are required, including fire trolleys. A fire trolley, typically a wheeled fire extinguisher, can be pushed (or pulled) to the fire scene by one person. Under pressure, the trolley releases the extinguishing agent to extinguish the fire.
[0003] When the fire extinguishing cart is in use, after the cart is moved to the fire scene, the pipe of the fire extinguishing tank is held and aimed at the fire point. After the valve is opened, the fire extinguishing agent in the fire extinguishing tank is ejected from the end of the pipe at high pressure, thereby achieving the effect of extinguishing the fire. However, in existing fire extinguishing carts, the fire extinguishing tank is directly placed on the cart frame and is stabilized to a certain extent by a limit frame. However, the upper end of the fire extinguishing tank is not effectively pressed and fixed. When the fire extinguishing cart is pushed or pulled, the fire extinguishing tank shakes on the cart frame, affecting the normal movement of the entire fire extinguishing cart. At the same time, the fire extinguishing cart has no structure to store and fix the pipe. The pipe on the fire extinguishing tank is directly placed on the upper end of the fire extinguishing tank after being rolled up. It is easy to become loose during transportation, and the staff needs to re-roll it, which makes the storage stability poor. Utility Model Content

[0019] When using the fire extinguishing cart, the staff pushes or pulls the frame 1 through the handrail 4, and the frame 1 moves through the wheels 2. When the fire extinguishing cart is moved to the fire scene, the limiting fixing structure 5 is operated to make way, and the connecting pipe 8 at the end 7 is held at the fire point. After opening the valve, the fire extinguishing agent inside the fire extinguishing tank 6 is ejected from the end of the connecting pipe 8 at high pressure, thereby extinguishing the fire. In the process of moving the fire extinguishing cart, the limiting frame 3 cooperates with the limiting fixing structure 5 to ensure the stability of the fire extinguishing tank 6. When the fire is extinguished, the winding connecting pipe 8 is placed on the upper end of the fire extinguishing tank 6, and the limiting fixing structure 5 is used to press and fix it. When the fire extinguishing tank 6 needs to be replaced, the limiting fixing structure 5 is also operated to make way, and the fire extinguishing tank 6 is taken out and replaced. After replacement, the limiting fixing structure 5 is used to fix and limit it.
[0020] According to the above embodiment, the position-limiting fixing structure 5 includes a fixing rod 501, a connecting plate 502, a connecting screw 503, a nut 504 and a limiting ring 505.

The tightening spring 5096 is connected between the tightening plate 5094 and the adjusting block 5092. By setting the limit fixing structure 5, the fire extinguishing tank 6 can be effectively pressed and fixed to ensure the stability of the fire extinguishing tank 6. The connecting plate 502 is installed on the fixing rod 501 through the connecting screw 503 and the nut 504, and can be adjusted to a certain height, which is suitable for fire extinguishing tanks 6 of different heights. In order to carry out the pressing and fixing work, a fixing column 508, a pressing plate 506 and an elastic component 509 are set on the connecting plate 502. When the connecting pipe 8 for spraying the fire extinguishing agent is rolled up and placed on the upper end of the fire extinguishing tank 6, the elastic component 509 can be used to press the pressing plate 506 tightly against the connecting pipe 8 to ensure the stability of the connecting pipe 8 after storage. A waist-shaped hole 507 is provided on the pressing plate 506 to facilitate the pulling and pulling of the pressing plate 506 to make it convenient to hold the connecting pipe 8 for fire extinguishing. The elastic component 509 is installed in a threaded connection manner and can be adjusted in height according to actual conditions. It has high flexibility and adaptability.
[0021] After the fire extinguisher 6 is placed on the vehicle frame 1, the limiting ring 505 is placed on the upper end of the fire extinguisher 6, the connecting screw 503 on the connecting plate 502 passes through the fixing rod 501, and a nut 504 is set at the lower end of the connecting screw 503, so that the limiting ring 505 is tightly pressed on the fire extinguisher 6, thereby completing the fixation of the fire extinguisher 6, and then the pressure plate 506 is set on the fixing column 508 through the waist-shaped hole 507, and the adjusting block 5092 in the elastic component 509 is installed on the stud 5091 through the screw hole 5093, and the connecting sleeve 5095 and the pressing plate 5094 at the lower end of the tightening spring 5096 are set on the fixing column 508. Under the action of the tightening spring 5096, the tightening plate 5094 exerts a force on the pressure plate 506, so that the pressure plate 506 is tightly pressed on the rolled connecting tube 8.
