[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution: a cantilever axial flow fan platform, including an outer frame 10, channel steel 20, angle steel 30, cushion block 40, protective fence 50, ladder 60, protective cage 601, gear lever 602, card slot 603, anti-slip pad 604 and reflective strip 605;

[0029] This cantilever axial flow fan platform is convenient for improving the safety and stability of the device. The specific implementation method is as follows:

[0030] The outer frame 10 is set as a square structure with openings at both the top and bottom, and channel steel 20 is arranged on the surface of the outer frame 10; a plurality of angle steels 30 are arranged on the surface of the outer frame 10, a cushion block 40 is installed on the top surface of the outer frame 10, and a guardrail 50 is connected to the top surface of the outer frame 10. A ladder 60 is welded and installed on the surface of the outer frame 10, and a safety cage 601 is fixedly connected to the surface of the ladder 60. An anti-slip mechanism is arranged on the surface of the ladder 60, and the anti-slip mechanism includes: a retaining rod 602 is rotatably installed on one side surface of the ladder 60, and a clamping groove 603 is fixedly connected to one side surface of the ladder 60. Anti-slip pads 604 are arranged around the tread bars of the ladder 60, and reflective strips 605 are symmetrically arranged on the tread bars of the ladder 60. Reflective strips 605 are symmetrically arranged on the surface of the retaining rod 602. The channel steel 20 is horizontally installed on the surface of the outer frame 10, and the cushion block 40 is installed on the surface of the channel steel 20. The channel steel 20 is horizontally installed on the surface of the outer frame 10 and is installed on the outer side surface of the outer frame 10. The angle steels 30 are diagonally installed on the four side surfaces of the outer frame 10, and the two ends of the angle steels 30 are in contact with the channel steel 20. The ladder 60 is connected to the surface of the guardrail 50, and the positions of the ladder 60 and the guardrail 50 are staggered. An opening is arranged at the overlapping part of the ladder 60 and the guardrail 50. The retaining rod 602 is arranged at the opening of the ladder 60 and the guardrail 50, and one end of the retaining rod 602 is rotatably connected to the ladder 60. The other side of the retaining rod 602 is correspondingly arranged with the clamping groove 603, and the clamping connection is between the clamping groove 603 and the retaining rod 602.

[0031] As Figure 1 , the channel steel 20 is welded to the outer surface around the outer frame 10. At the same time, the two ends of the angle steel 30 are welded to the diagonal positions on the outer sides around the outer frame 10. The ends of the angle steel 30 are in contact with the channel steel 20 on the upper and lower sides. At this time, the strength of the outer frame 10 can be increased, and the stability of the support for the axial flow fan can be increased. At the same time, the guardrail 50 can shield the outside of the outer frame 10 and protect the workers. At the same time, when the worker stands above the outer frame 10, the end of the retaining rod 602 is clamped inside the clamping groove 603. At this time, the retaining rod 602 can protect the opening of the ladder 60 and the guardrail 50 to prevent the worker from falling from this place;

[0032] Meanwhile, the worker climbs the ladder 60. At this time, the worker enters the space between the ladder 60 and the protective cage 601. At this time, the protective cage 601 can enhance the safety of the device. At this time, the hands and feet of the worker come into contact with the anti-slip pad 604, and the friction is increased through the anti-slip pad 604, which can prevent slipping during climbing. At the same time, the reflective strip 605 on the surface of the ladder 60 can prompt the worker's foothold, enhancing the safety of the ladder 60. When the worker climbs to the opening between the ladder 60 and the guardrail 50, one side of the shift lever 602 can be pushed upward, so that the end of the shift lever 602 at this position is taken out from the inside of the card slot 603. At this time, the other side of the shift lever 602 rotates on the surface of the ladder 60, so that the shift lever 602 is moved out from the opening between the ladder 60 and the guardrail 50. At this time, the worker enters above the outer frame 10 from the opening between the ladder 60 and the guardrail 50. At this time, the shift lever 602 is rotated in the reverse direction again, so that the shift lever 602 is engaged with the card slot 603.

[0033] Working principle: When using this cantilever axial flow fan platform, the channel steel 20, angle steel 30, shift lever 602, and card slot 603 are provided, which can improve the safety of the platform and increase the overall practicality.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
