Evacuation ladder with adjustable level

Abstract

The invention discloses a horizontal-height-adjusting evacuating escalator and relates to the field of evacuating escalators. The evacuating escalator comprises a stand column guiding mechanism, a connecting rod mechanism, a driving mechanism and side supports. A movable pedal is arranged between the side supports. The stand column guiding mechanism comprises a lifting chain and a stand column. A guiding groove is formed in the stand column. The stand column is connected with the side supports. The connecting rod mechanism comprises a connecting rod plate, a chain fixing plate and a guiding shaft. The connecting rod plate is movably connected to one side of the stand column. The lifting chain is movably connected to the other side of the stand column. The chain fixing plate is connected to the middle portion of the lifting chain. The two ends of the guiding shaft penetrate through the connecting rod plate and the guiding groove respectively and then are connected with the chain fixing plate. The movable pedal is movably connected with the side supports. A pedal connecting rod is arranged on one side of each support. The movable pedal is connected with the pedal connecting rods which are connected with the connecting rod plate. The horizontal-height-adjusting evacuating escalator is convenient to use, resources can be saved, practicability is high, the safety of evacuating can be increased, labor intensity can be lowered, and the reliability of the escalator can be guaranteed.

Description

technical field [0001] The invention relates to the field of evacuation escalators, in particular to an evacuation escalator for adjusting the horizontal height. Background technique [0002] The evacuation escalator is a kind of equipment used for evacuation of personnel in emergency situations in large-scale equipment and places such as airports, docks, road traffic, factories and mines. At present, most evacuation escalators are fixed evacuation escalators. The dimensions of the fixed evacuation escalators are fixed and cannot be adjusted in height. In order to adapt to the evacuation of people in different places, the user often needs to configure fixed evacuation escalators of various heights to adapt to emergency situations. , resulting in unnecessary waste of resources. If there are special circumstances, this type of escalator will not be able to adapt to the application under various conditions, such as the height of the existing escalator is not enough, the terrai...

Problems solved by technology

At present, most evacuation escalators are fixed evacuation escalators. The dimensions of the fixed evacuation escalators are fixed and cannot be adjusted in height. In order to adapt to the evacuation of people in different places, the user often needs to configure fixed evacuation escalators of various heights to adapt to emergency situations. , resulting in unnecessary waste of resources

In case of special circumstances, this type of escalator will not be able to adapt to the application under various conditions, such as the height of the existing escalator is not enough, the terrain is complex and difficult to move, etc., and the practicability is poor

[0003] In the case of emergency evacuation, when it is necessary to evacuate people at different heights, it is necessary to place multiple sets of fixed evacuation escalators, and placing multiple sets of fixed evacuation escalators will take a long time, which will increase the evacuation time. Seriously affect the speed of evacuation. At the same time, placing multiple sets of fixed evacuation escalators in a short period of time will also increase labor intensity.
