Detailed Description

The escape ladder (1) is high-temperature resistant by adopting an aluminum alloy material, a glass enclosing wall is replaced by a front end baffle (9), the outer surface of the baffle is made of the same material as that of a glass curtain wall and is attached to the baffle, the escape ladder is arranged on a track (5) and is controlled to slide by a three-phase motor (6), a control box is arranged on the wall surface of a refuge layer, the motor is controlled to rotate forwards, reversely, stop and open an electromagnetic lock (7), a special power supply for the refuge layer is used and is provided with a battery, the power failure caused by fire disaster is prevented, two sides of the escape ladder (1) are used for hanging a rope (4) by welding metal rings (10) inside and two rows of universal beads (11) outside and are welded on the two sides to reduce friction, the universal beads are sunken in the escape ladder, one bead is arranged in each meter, the design friction of the escape ladder is increased except for ripples (12) on, this structure can ensure that personnel slowly, safely walk down behind the rotatable part of front end rotation downwards, and the front end adopts electromagnetic lock (7), the double-lock insurance design of mechanical lock, if need the downward rotation then open mechanical lock before escape ladder (1) stretches out, treat that the escape ladder stretches out the back and open electromagnetic lock (7), and rotation angle can be adjusted as required.

The track (5) is divided into three parts, all made of aluminum alloy, two sides of the middle gear way (14) are meshed with the concave slideways on the two sides, the two layers of concave slideways are fixed on the ground of a refuge layer after the escape ladder (1) is placed, the gear way (14) is converted into a smooth plane after the end of the escape ladder is reached, and the escape ladder is braked together with the self-locking motor by matching the concave limiting slideways, so that the stability of the escape ladder is ensured.

Lifting rope (2) and screen cloth (3) combine together, all adopt the fire prevention, it is heat-resisting, resistant drawing, the material, fixing on the roof directly over refuge layer track lifting rope (2) upper end, adjustable fastening degree, below end-to-end connection D type padlock (4), hang during the use on escape ladder both sides becket (10), lifting rope (2) increase in proper order to the out-of-building length from the building, treat that every lifting rope (2) pulling force is the same after escape ladder (1) stretches out, screen cloth (3) are used for the security of protection personnel to fix on lifting rope (2), screen cloth (3) are parallel from top to bottom after escape ladder (1) stretches out, screen cloth (3) outside excessive part is used for hanging on escape ladder (1) front end baffle (9) becket, both can stabilize escape ladder (1) and can protect personnel's security again.

The device has the advantages that the device is large in size, is very suitable for being installed on an empty refuge layer, is simple to operate, can provide boarding platforms for rescuing unmanned aerial vehicles and rescuing helicopters when a fire disaster happens, increases the distance between the unmanned aerial vehicles and the helicopters and buildings, ensures safety, and is added with a new fire rescue mode.
