Landscape elevator escape door opening method

Abstract

The invention relates to an underground landscape elevator horizontal type escape door opening method. A first door panel, a second door panel, a lower base, a first rotation shaft, a second rotationshaft, a wheel, a chain, a fixed pulley, a heavy object, a hinge supporting rod, a clamp groove, a sliding way, a longitudinal beam, a transverse beam, a panel and pins are included. When the emergency situation happens, a person firstly dismounts the pins, located at the upper end of the heavy object, limiting heavy object moving in the underground space, then, the chain at the position of the heavy object is pulled by hand, the hinge supporting rod generates vertical upward force to the first door panel and the second door panel under the action of the chain, meanwhile, the wheel rolls in the sliding way under the action of the traction force of the chain, the first door panel rotates around the second rotation shaft, and the second door panel rotates around the first rotation shaft andis folded. When the wheel arrives at the position of the clamp groove, the wheel falls into the clamp groove of the lower base, the door is opened, and trapped crowds can rapidly, effectively and safely excavate. According to the opening method, manual opening is adopted, and the opening method is simple, reliable, safe and effective.

Description

technical field [0001] The invention relates to a method for opening an escape door of an underground landscape ladder, which belongs to the field of escape doors. Background technique [0002] With the rapid development of economy and society, large-scale and comprehensive urban underground spaces are constantly being developed and constructed. Underground commercial buildings have special spatial structures, dense population, high fire risk, and difficult rescue, so their fire evacuation safety is particularly important. . At present, most of the escape doors in our country are vertical doors installed on the ground, which are in the form of side-hung doors opened on both sides. However, in terms of economy and safety, such doors are generally locked, which has great potential Potential safety hazards, and the existing double-leaf doors are found in use. When an emergency occurs and the crowd needs to be evacuated quickly, the state of the door will affect the evacuation ...

AI Technical Summary

Problems solved by technology

At present, most of the escape doors in our country are vertical doors installed on the ground, which are in the form of side-hung doors opened on both sides. Potential safety hazards, and the existing double-leaf doors are found in use. When an emergency occurs and the crowd needs to be evacuated quickly, the state of the door will affect the evacuation efficiency of the crowd. When the double-leaf doors are fully opened, the crowd will move towards the door. Evacuation in one direction makes the door crowded or even a stampede occurs, which greatly reduces the safety of the escape door
