In order to make the back of the fixing frame (2) flat, the telescopic ladder fixing head (19) uses a countersunk screw to pass through the countersunk hole on the back of the fixing frame (2).

[0034] The second part, the support unit mainly includes a support frame (3), a housing (5), a maintenance light (16), a lighting light (6), a vent (11), a vent jacket (12), a fixture mounting plate (10), a lock (14), a handle (8), and a button (13). The support frame (3) is connected to one end of a hinge through a screw and nut, and the other end of the hinge is connected to a fixed frame (2) through a screw and nut. The support frame (3), the housing (5), the maintenance light (16), the lighting light (6), the fixture mounting plate (10), the lock (14), and the handle (8) are all fixed to the support frame (3) through screws, so that the support frame (3) is rotatably connected to the fixed frame (2) through two pairs of hinges. The button (13) passes through the mounting hole on the housing (5) and is tightened using its own screws. The vent (11) passes through a hole on the housing (5) and is screwed to the vent jacket (12). A rubber pad (29) is attached between the vent jacket (12) and the housing (5). The friction force generated by the compression of the rubber pad (29) is used to fix the vent jacket (12) and the vent (11) on the housing (5). The specific connection structure of the vent (11) is as follows: Figure 5 As shown, the ventilation holes are used to facilitate the sound transmission of the subsequently installed speakers (44) and to trigger the smoke sensor (42) through the ventilation holes when a fire occurs. At the same time, the lock buckle (14) can be locked with the electronic lock (15) fixed on the fixing frame (2). After the electronic lock is locked, the maintenance platform is retracted, saving space in the simulator and ensuring that the aisle below the maintenance platform is unobstructed.

[0035] The housing (5) is made of glass fiber reinforced plastic. A groove is formed on the outer surface of the housing (5) to sink the lighting lamp (6), the handle (8) and the button (13) therein, and the mounting threaded hole of the handle (8) is used as a fixing point to connect the support frame (3) and the housing (5). The handle (8) and the support frame (3) are mounted in the groove of the housing (5) by screws and nuts, and the lighting lamp (6) is mounted in the groove. The lighting lamp (6) covers the screws and nuts, so as to ensure that the lower surface of the maintenance platform is flat and no screws or nuts are exposed.

[0036] The third part, the fixture unit is a set of fixtures (9), the specific structure is as follows Figure 2As shown, it mainly includes a clamp (25), a chuck (27), a spring (23), a quick release (24), and a rubber sticker (26). The quick release (24) passes through the clamp (25), the spring (23), the nut (22), the chuck (27), and the hand-tightening nut (28) in sequence, and the chuck (27) is fixed to the quick release (24) of the eccentric structure through the nut (22) and the hand-tightening nut (28), and then the rubber sticker (26) is attached to the clamping surface of the clamp (25) and the chuck (27), and the clamp (9) is clamped and released by toggling the quick release (24) and utilizing its eccentric structure. The clamp (9) is rotatably connected to the clamp mounting plate (10) fixed on the support frame (3) through a hinge; the rubber sticker (26) is adhered to the clamping surface of the clamp (25) and the chuck (27) through its own adhesive. The clamping plate (25) is fixed to the hinge by screws, and the other end of the hinge is fixed to the fixture mounting plate (10) by screws.

[0037] The fourth part, the telescopic ladder unit mainly includes a telescopic ladder (17), a telescopic ladder rotating head (18), and a tension gas spring (7). After the telescopic ladder rotating head (18) is inserted into the vertical pipe of the telescopic ladder (17), the two parts are fixed from the side with screws and nuts. The axial screw (30) passes through the deep groove ball bearing (31) in the inner hole of the telescopic ladder rotating head (18) and the telescopic ladder fixed head (19), so that the telescopic ladder (17) can rotate around the telescopic ladder fixed head (19). The specific connection structure is as follows: Figure 6 One end of the two rotating heads of the tension gas spring (7) is fixed to the fixed head (19) of the telescopic ladder by means of screws and nuts, and the other end of the rotating head is fixed to the support frame (3); the tension gas spring (7) is used to provide tension to offset gravity, thereby reducing the labor intensity during operation.

[0038] The fifth part mainly includes a handrail (20) and a handrail reinforcement plate (21). Screws pass through the handrail (20), the gantry (40), and the handrail reinforcement plate (21) in sequence to fix them on the gantry (40). The handrail reinforcement plate (21) is placed on the back of the gantry (40) to increase the contact area.

[0039] Auxiliary items such as speakers (44), temperature and humidity sensors (41), smoke sensors (42), sound and light alarms (43) etc. can be installed at appropriate locations on the maintenance platform as needed. Figure 4 shown.

[0040] The retracting and releasing process of the present invention:

[0041] After holding the handle (8) with both hands, press the button (13) with the thumb of the right hand, the electronic lock (15) opens, and the housing (5) is rotated and lowered. Since the rotation center of the telescopic ladder (17) does not coincide with the rotation center of the maintenance platform support frame (3), the support frame (3) and the telescopic ladder (17) produce relative motion when rotating. In order to ensure smooth rotation of the support frame (3), the clamp (9) is rotatably connected to the support frame (3). The clamp (9), the telescopic ladder (17), the support frame (3), and the fixed frame (2) form a crank slider mechanism, the principle of which is as follows: Figure 4 shown.

[0042] After the maintenance platform is lowered, the quick release (24) of the clamp (9) is opened, and the distance between the clamp (25) and the clamp (27) increases under the action of the spring force, thereby loosening the crossbeam of the telescopic ladder (17). The telescopic ladder (17) is first pushed upward and then rotated outward and pulled down to the ground. The steps of folding up are opposite to those of putting down.

[0043] Finally, the support frame (3) and the fixing parts thereon can rotate relative to the fixing frame (2) around the hinge axis, the clamp (9) can rotate relative to the support frame (3) around the hinge axis, the telescopic ladder (17) can rotate relative to the fixing frame around the inner hole axis of the telescopic ladder fixing head (19), and the fixing frame (2) is fixed on the gantry (40). The effect of the maintenance platform when it is finally used is as follows: Figure 7 shown.

[0044] The present invention has a simple structure, is safe and reliable, and is easy to operate. By fixing the rotating connection point of the telescopic ladder (17) on the fixed frame (2) rather than the support frame (3), the total height requirement of the telescopic ladder is met while the height of the handle (8) of the maintenance platform is effectively reduced. The maintenance personnel can directly operate the maintenance platform by hand without the help of a pull rod. Therefore, more auxiliary items can be integrated on the maintenance platform without worrying about operating difficulties due to excessive weight. The clamp (9) is rotatably connected to the support frame (3) through a hinge to ensure that the maintenance platform rotates smoothly after the electronic lock (15) is quickly opened. The lighting lamp (6), handle (8), and button (13) are sunk into the housing (5), and the screws and nuts used for connection are covered at the same time, so that the lower surface is flat.

[0045] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.
