A stable fire ladder

Abstract

The invention relates to a stable type fire ladder. The stable type fire ladder comprises a first cat ladder and a second cat ladder, and further comprises a fixing mechanism and a connection mechanism, wherein the fixing mechanism comprises a supporting rod, a fixed sleeve, a second transmission rod, two first transmission rods, two movable sleeves, two clamping rods and two first springs; the connection mechanism comprises two movable blocks and two clamping assemblies; each clamping assembly comprises a connection shaft, a rotary sleeve, a rotary rod, a connection block, a second spring andtwo supporting plates. In the stable type fire ladder, the fixing mechanism drives the two clamping rods to move, so that the connection stability between the fire ladder and a windowsill is improvedthrough the clamping rods, and furthermore, the climbing safety of firefighters is improved; the connection mechanism can be used for enabling the second cat ladder to move along the first cat ladder; meanwhile, the connection and separation between the first cat ladder and the second cat ladder are realized, so that the convenience of storing the fire ladder is improved and the practicability ofthe fire ladder is improved.

Description

technical field [0001] The invention relates to the field of fire emergency equipment, in particular to a stable fire ladder. Background technique [0002] Fire-fighting facilities refer to fixed facilities such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings. Automatic fire-fighting facilities are divided into electrical system automatic facilities and water system automatic facilities. Electrical fire safety testing is based on the electrical facilities during operation. Modern physical phenomena such as thermal radiation, acoustic emission, and electromagnetic emission, adopt international advanced high-tech instruments and equipment, combined with traditional inspection methods to carry out all-round quantitative monitoring of electrical facilities, so as to reflect electrical fires more comprehensively, scientifically and accurately The existence of hidden dangers, the degree of danger and their exact locations, and correspo...

AI Technical Summary

Problems solved by technology

[0003] As a kind of fire-fighting equipment, the fire ladder plays an important role in the fire rescue process. When a fire occurs, the firefighters will hang the fire ladder on the window upstairs at the bottom of the building, and then the firefighters will pass the fire. The ladder climbs up the stairs. In the process, there is no effective fixation between the fire ladder and the window sill of the window, which reduces the stability of the fire ladder, thereby reducing the safety of firefighters climbing. Not only that, but generally in order to be able to climb On higher floors, the length of the fire ladder is longer, which makes the transportation of the fire ladder more difficult, thereby reducing the practicality of the fire ladder
