Portable fire-fighting ladder with security performance

Abstract

The invention discloses a portable fire-fighting ladder with security performance. The portable fire-fighting ladder with the security performance comprises hanging hooks, a main rod and additional rods; the hanging hooks are rotatably connected with the main rod through a threaded connecting rod and a first circular groove; a regulating rod is inserted into the inner cavity of the first circulargroove in a sliding manner; first regulating grooves and second regulating grooves are respectively formed in the left end and the right end of each of the main rod and the additional rods; the bottomside wall of the inner cavity of each first regulating groove and each second regulating groove is rotatably connected with a supporting plate; the tip of each supporting plate is rotatably hinged toa pedal; the tip of each pedal is rotatably connected with the side wall of the regulating rod through a rotating block; a second circular groove of the main rod is connected with one regulating rodof the additional rod through screw threads in a plugging manner; a T-shaped lifting groove is formed in the vertical direction of the side walls of each of the main rod and the additional rods; the vertical direction of the inner cavity of the T-shaped lifting groove is clamped with a safety belt locking mechanism in a sliding manner. The portable fire-fighting ladder with the security performance is convenient to combine and convenient to accommodate, facilitates the use in a place where large rescue equipment cannot reach, and facilitates repeated use.

Description

technical field [0001] The invention relates to the technical field of fire-fighting related applications, in particular to a portable fire-fighting ladder with security performance. Background technique [0002] Today's firefighting facilities are very complete, gradually developing in the direction of intelligence, and the firefighting emergency warning mechanism is also very sound. Once an alarm notification is received, they will rush to the scene as quickly as possible. Fast, but there will still be some urban villages with narrow roads, and large fire trucks cannot reach them. They can only carry equipment on foot to carry out emergency rescue. Therefore, for firefighters, the equipment they carry has both functions. , and the structure is simple, which can speed up the speed of arriving at the scene. We know that the existing fire ladder is large in size, and the length can be retracted and elongated, but it is still troublesome to carry. Therefore, we design and prod...

[0002] Nowadays, the fire-fighting facilities are very complete, gradually developing towards the direction of intelligence, and the fire-fighting emergency warning mechanism is also very sound. Fast, but, there will still be some urban villages with narrow roads, and large fire trucks cannot reach the phenomenon. They can only carry equipment and rush to the phenomenon on foot for emergency rescue. Therefore, for firefighters, the equipment they carry is multi-functional , and the structure is simple, which can speed up the speed of reaching the scene. We know that the existing fire ladders are large in size, and the length can be contracted and elongated, but it is still troublesome to carry, so here we design and produce a kind of safety ladder. Portable fire ladder for multiple uses
