[0009] The setting of the locking bolt can prevent the supporting legs from automatically rotating and changing their positions after being subjected to force, thereby affecting the stability of the base frame.
[0010] Furthermore, the base frame includes a T-shaped mounting plate and two rear leg mounting plates, a ground nail is provided at the middle position of the lower surface of the T-shaped mounting plate, the middle end of the T-shaped mounting plate is connected to the mounting seat, and the other opposite ends of the T-shaped mounting plate are respectively hinged with support legs, and the two rear leg mounting plates are arranged on the mounting seat at two symmetrical ends away from the side of the T-shaped mounting plate, and each of the rear leg mounting plates is hinged with a support leg.
[0011] The T-shaped mounting plate and two rear leg mounting plates facilitate disassembly and replacement of components, making maintenance easier. The simple structure and light weight make it more portable. Ground spikes are located in the middle of the chassis to ensure better stability and prevent easy displacement.
[0012] Furthermore, the mounting base is detachably connected to the base frame.
[0013] The mounting base and the base frame are detachably connected, making it easy to store and replace parts.
[0014] Furthermore, a connecting plate is provided at one end of the base frame, and a hook and pull ring is provided on the connecting plate.
[0015] The mounting plate is mainly used to fix the hook pull ring. The setting of the hook pull ring makes it convenient to pull or lift the fire monitor through a wire rope or a lifting rope.
[0016] Furthermore, a weight-reducing long hole is provided on the side surface of the supporting leg.
[0017] The setting of the weight-reducing long holes makes it easy to reduce the weight of the supporting legs, making it lighter to carry.
[0018] Furthermore, an identification strip is provided on the top surface of the supporting leg.
[0019] The setting of the identification strip helps to remind the position of the supporting legs to prevent firefighters from tripping, and also serves as an identification and distinction.
[0020] Beneficial effect: The utility model fixes the mobile fire cannon on the mounting base. When not in use, the supporting legs are folded and stored at the base frame, which is convenient for carrying and storage and does not take up space. When needed, each supporting leg is rotated and unfolded and fixed to the ground to ensure the stability of the base frame. The setting of the mounting base position structure makes it easy to shift the center of gravity to the rear, and the distance between the two rear supporting legs is smaller, which will make the center of gravity more stable and provide stronger supporting force, thereby ensuring the stability of the fire cannon base frame.
