[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] See attached document Figure 1-10 As shown, a suspended platform fixing system includes a lifting mechanism 3 and a fixing mechanism 4. The lifting mechanism 3 includes a main positioning frame 311, which is installed on the roof of the building. A column a3111 and a counterweight 313 are mounted on the main positioning frame 311. A longitudinal beam 314 is mounted on the column a3111, and a winch 32 is mounted on the longitudinal beam 314. The fixing mechanism 4 includes a housing 41, a bottom cover 43 on the side of the housing 41 closest to the building, and a lifting ring 42 on the top of the housing 41. The lifting ring 42 is connected to the lifting rope 32 of the winch 32. 1. The bottom side of the outer casing 41 is connected to the bottom of the suspended basket 1 via a chain 6. An elongated hole 431 is provided on the bottom cover 43. An electromagnet 45 is fixedly installed on the inner side of the bottom cover 43. An anchoring device 44 is provided on the side of the electromagnet 45 away from the bottom cover 43. The side of the anchoring device 44 near the bottom cover 43 can move in the elongated hole 431 and contact the building. The control cabinet 2 is electrically connected to the winch 32 and the anchoring device 44 to control the operation of the anchoring device 44 and the electromagnet 45. It is also used to control the winch 32 and the suspended basket 1 to run synchronously during the lifting and lowering process.

[0033] It should be noted that the path of the fixing mechanism 4 is located in the part of the building containing steel bars so that the electromagnet 45 can perform magnetic attraction. The control cabinet 2 controls the operation of the basket 1 through the controller installed inside it (not shown in the attached figure). The anchoring device 44 and the winch 32 are both electrically connected to the controller to achieve the effect of being controlled.

[0034] Specifically, during the process of controlling the raising or lowering of the suspended platform 1 through the control cabinet 2, the control cabinet 2 synchronously controls the winch 32 to wind or unwind, so that the fixing mechanism 4 rises or falls synchronously with the suspended platform 1. During the operation on the suspended platform 1, if strong winds occur, in order to evacuate from the suspended platform 1 in time, the fixing mechanism 4 is activated through the control cabinet 2. The anchoring device 44 and electromagnet 45 in the fixing mechanism 4 are activated in sequence. The electromagnet 45 is attracted by the magnetic force of the steel bars inside the building, fixing the fixing structure to the wall of the building. Since the fixing mechanism 4 and the suspended platform 1 are connected by the chain 6, the position of the suspended platform 1 is fixed after the fixing structure is fixed.

[0035] In the above-mentioned sequential startup, the anchoring device 44 is started first, followed by the electromagnet 45. When shutting down, the operation is reversed.

[0036] In a preferred embodiment, a winding and unwinding device (not shown in the drawings) can also be provided at the bottom of the suspended basket 1. After the fixing mechanism 4 is activated, the winding and unwinding device winds up the chain 6 to further fix the suspended basket 1 and achieve a better fixing effect. The winding and unwinding device can be a winch 32.

[0037] In another preferred embodiment, a sensor (not shown in the figures) and an anemometer (not shown in the figures) may also be installed on the suspended platform 1. The sensor and anemometer are electrically connected to the controller in the control cabinet 2. When the swaying amplitude of the suspended platform 1 is detected to exceed the set threshold, the control cabinet 2 activates the fixing mechanism 4. The electromagnet 45 is magnetically attracted to the steel bars inside the building, fixing the fixing structure to the wall of the building. At the same time, the previously activated anchoring device 44 further enhances the anchoring effect with the wall. When the wind speed is lower than the threshold, the fixing mechanism 4 is automatically shut off or manually shut off.

[0038] See attached document Figures 1-2 As shown in Figures 5 to 10, in this embodiment of the invention, the anchoring device 44 includes a rack 441, a connecting frame 444, and a bracket 445. The rack 441 is inserted into the interior of the elongated hole 431. Baffles 442 are provided at both ends of the rack 441. A spring 443 is provided between the baffles 442 and the bottom cover 43. The connecting frame 444 covers the outside of the electromagnet 45 and does not contact the electromagnet 45. The bracket 445 is fixedly provided on the side of the electromagnet 45 away from the bottom cover 43. A motor 446 is provided on the bracket 445. The output end of the motor 446 is connected to a lead screw 447. The lead screw 447 is threadedly connected to the center of the connecting frame 444.

[0039] It should be noted that when the anchoring device 44 is not activated, the rack 441 is retracted into the elongated hole 431 on the side near the building. The rack 441 is made of aluminum alloy and has a toothed groove on the side near the building. The surface of the rack 441 on the side near the building is coated with a rubber coating to further prevent it from sliding on the wall and enhance the anchoring effect with the building wall.

[0040] Specifically, the motor 446 is electrically connected to the controller inside the control cabinet 2. When the control cabinet 2 starts the fixing mechanism 4, the control cabinet 2 controls the motor 446 to rotate forward. The motor 446 drives the rack 441 to extend out from the elongated hole 431 and abut against the building wall through the threaded connection between the lead screw 447 and the connecting frame 444, thus preventing the fixing mechanism 4 from sliding on the building wall during the swing of the suspended basket 1.

[0041] In a preferred embodiment, a lip is provided at the elongated hole 431 on the inner side of the bottom cover 43 to guide the rack 441.

[0042] In another preferred embodiment, a magnetic shielding sheet 5 made of iron-nickel alloy is also provided between the electromagnet 45 and the bracket 445 to reduce the influence of the electromagnet 45 on the motor 446.

[0043] See attached document Figures 1-8As shown, in a preferred embodiment of the present invention, an auxiliary positioning frame 312 is also included. The auxiliary positioning frame 312 is set on the ground floor of the building. A counterweight 313 and a column b3121 are provided on the auxiliary positioning frame 312. A crossbeam b316 is provided on the column b3121. A crossbeam a315 is also provided on the longitudinal beam 314. Two cables 317 are provided between the crossbeam a315 and the crossbeam b316. Through holes 411 are opened on both sides of the top of the outer shell 41. The cables 317 pass through the through holes 411 and do not contact the anchoring device 44.

[0044] Specifically, the fixing mechanism 4 is guided and limited by two cables 317, which can prevent the fixing mechanism 4 from swinging and being difficult to fix to the wall in windy weather. At the same time, it can also fix the position of the suspended basket 1. Combined with the fixing mechanism 4 and the wall, the position of the suspended basket 1 is further fixed, and the fixing effect is enhanced.

[0045] The specific working principle of this suspended platform fixing system is as follows: During the ascent or descent of the suspended platform 1, the control cabinet 2 synchronously controls the winch 32 to wind or unwind, causing the fixing mechanism 4 to rise or fall synchronously with the suspended platform 1. If strong winds occur during operation on the suspended platform 1, and to facilitate timely evacuation, the control cabinet 2 activates the fixing mechanism 4. First, the anchoring device 44 is activated, followed by the electromagnet 45. After the control cabinet 2 activates the fixing mechanism 4, it controls the motor 446 to rotate forward. The motor 446, through a lead screw 447 threaded connection to the connecting frame 444, drives the rack 441 to extend from the elongated hole 431 and abut against the building wall. When the control cabinet 2 starts the fixing mechanism 4, the electromagnet 45 attracts the steel bars inside the building with magnetic force, fixing the fixing structure to the wall of the building. On the other hand, the fixing mechanism 4 is guided and limited by two cables 317, which can prevent the fixing mechanism 4 from swinging and not being easy to fix to the wall in windy weather. At the same time, it can also fix the position of the suspended basket 1. Combined with the fixing mechanism 4 and the wall, the position of the suspended basket 1 is further fixed, enhancing the fixing effect. This solves the problem that the suspended basket 1 will swing violently due to strong airflow during the use of the suspended basket 1, which may lead to safety accidents.

[0046] It should be noted that the specific models and specifications of the winch 32, control cabinet 2, motor 446 and electromagnet 45 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0047] The power supply and operating principle of the winch 32, control cabinet 2, motor 446 and electromagnet 45 are clear to those skilled in the art and will not be described in detail here.

[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
