The escape sliding frame (2) is arranged in the escape sliding rail (1) and used for bearing sliding movement of an evacuee to the ground, and comprises a bearing beam (7) with one end used for hanging a load, an upper supporting wheel shaft (12) rotationally connected with the other end of the bearing beam (7), an upper supporting wheel (11) rotationally connected with the outer end of the upper supporting wheel shaft (12) and meshed with the anti-slip travelling rack (4) for rotation, a supporting beam (9) with the upper end slidingly connected with a sliding groove arranged on one side of the bearing beam (7) and used for supporting and stabilizing the escape sliding frame (2) and enabling the escape sliding frame (2) to have a foldable connection function, a lower supporting wheel (10) rotationally connected with the lower end of the supporting beam (9) and used for matching the integral sliding of the escape sliding frame (2), and a damping descent control device (13) fixedly connected with the bearing beam (7) and rotationally connected with the upper supporting wheel shaft (12) and used for controlling the rotation speed of the upper supporting wheel (11) and further controlling the downward sliding speed of the escape sliding frame (2);
The escape slide rail (1) is formed by splicing a plurality of unit standard length modules;
The mounting holes (3) are oblong and are positioned on two sides of the back surface area of the escape slide rail (1);
The escape carriage (2) comprises a brake and slip speed control handle (14) which is arranged at one end of the bearing beam (7) close to an evacuee and used for controlling the slow-descent degree of the damping slow-descent device (13);
the number of the upper supporting wheels (11) is two, and the upper supporting wheels are symmetrically arranged about the bearing beam (7);
The escape slide rail 1 further comprises an anti-theft reverse travel stop tongue (5) which is arranged on the inner side of the back of the escape slide rail 1 and is used for playing an anti-theft role, one end of the anti-theft reverse travel stop tongue is rotationally connected with the inner side of the back of the escape slide rail 1, the anti-theft reverse travel stop tongue (5) is fixedly connected with one end of an elastic device capable of bouncing the anti-theft reverse travel stop tongue (5), and the other end of the elastic device is fixedly connected with the inner side of the back of the escape slide rail 1;
The number of the anti-theft reverse running stop tongues (5) is two, and the anti-theft reverse running stop tongues are symmetrically arranged opposite to the anti-skid running racks relative to the bearing beam (7);
The supporting beam (7), the supporting beam (9), the lower supporting wheel (10) and the upper supporting wheel (11) are arranged to form a stable double-triangle supporting structure, so that the structure of the escape carriage (2) is ensured to be reliable and stable; the upper end of the supporting beam (9) and the bearing beam (7) are arranged to slide relatively to form a folding and unfolding locking mechanism, so that the escape carriage (2) can be folded and stored, and the occupied storage space is reduced; the lower supporting wheel (10) runs in the middle of the escape slide rail (1) to ensure stable stress balance running;
The use process comprises the following steps:
S100, firstly, vertically and permanently mounting an escape slide rail (1) at a position which is close to an escape window (16) on an outer side wall body (15) of a high-rise building through a mounting hole (3), and when a dangerous situation occurs, mounting the escape slide rail (2) in the escape slide rail (1) and enabling an upper supporting wheel (11) on the escape slide rail (2) to be meshed with an anti-skid travelling rack (4) of the escape slide rail (1);
S200: the manned platform is hung to the extending end of the bearing beam (7) and fixedly connected with a hanging hole (6) arranged at the end part of the bearing beam (7), so that the manned platform is prevented from moving along the horizontal direction of the bearing beam (7);
s300, controlling the upper supporting wheel (11) to rotate through the damping descent control device (13) so as to be meshed with the anti-skid walking rack (4) for rotation, preventing the escape sliding frame (2) from deflecting in the falling process, and completing the lowering of the evacuee to the ground for escape;
The step S100 further includes the following steps:
s101: when the escape sliding frame (2) is arranged in the escape sliding rail (1), the escape sliding frame (2) is firstly inclined to enable the two upper supporting wheels (11) to be embedded into the opening of the escape sliding rail (1);
s102: rotating the escape sliding frame (2) to enable the two upper supporting wheels (11) to be embedded into the left side groove and the right side groove of the escape sliding rail (1);
s103: the escape carriage (2) is rotated to enable the two upper supporting wheel shafts (12) to be in a horizontal position, and the lower supporting wheels (10) are enabled to contact the escape sliding rail (1), at the moment, the escape carriage (1) is installed in place and is in a locking state, and an escape person to be escaped is hung and escaped through the safety belt.
2. A total floor sharing permanent wall-embedded high-rise building fire escape system as claimed in claim 1, wherein:
The number of the mounting holes (3) in the escape slide rail (1) is not less than 4.
