Description

Technical Field

[0001] This utility model relates to the field of maintenance technology, specifically a quick-assembly and assembly inverted ladder maintenance platform. Background Technology

[0002] The issue involves an AV100 electric blower. This model is quite large, and during maintenance, it was discovered that the bolts on the air cylinder mating surface are 2.05 meters above the ground. This is too high for an average person to stand on the ground to disassemble or install the bolts, and the maintenance space is too confined to accommodate mobile scaffolding or a lifting platform. Because the air cylinder mating surface bolts are large (a total of 136 bolts with 80mm nuts), specialized disassembly tools (hydraulic wrenches, electric hydraulic pumps) are required for their removal or installation.

[0003] Currently, patent application number 202020680837.6 discloses a maintenance platform for inspecting rail transit systems. The rail transit system includes tracks and trains traveling along the tracks. The maintenance platform includes a platform body and a guiding device. The platform body is adapted to be positioned on one side of the train's width. The lower end of the platform body has running wheels. The guiding device is connected to the platform body and has supporting components located on the side of the track and supporting the track to prevent the platform body from moving towards the train. Although the maintenance platform according to this utility model can protect the train, has good adaptability, and is simple, flexible, and has low maintenance costs, it has some drawbacks: it occupies a large area and is not easy to place, and its manufacturing cost is relatively high. It is also not flexible in its use and is not very convenient to operate during maintenance. Therefore, this utility model provides a quick-assembly and disassembly modular inverted ladder maintenance platform to solve the above problems. Utility Model Content

"Multiple" means two or more, and unless otherwise explicitly limited, all of them fall within the scope of protection of this utility model.

[0024] Example: Figure 1-3 This utility model provides a technical solution: including a first bracket 1, a protective frame 2, a connecting screw cylinder 3, a second bracket 5, and a foot platform 6. The inner end of the first bracket 1 is detachably connected to the second bracket 5 through a crossbeam 8. The first bracket 1 and the second bracket 5 have the same structure and are symmetrical. A connecting screw cylinder 3 is welded to the rear side of the top of both the first bracket 1 and the second bracket 5. A fixing bolt 4 is installed on the connecting screw cylinder 3.

[0025] Both the first bracket 1 and the second bracket 5 are equipped with an integrated protective frame 2 at the bottom front side. The foot platform 6 is detachably connected to the bottom inner side of the first bracket 1 and the second bracket 5 through a connecting rod 9.

[0026] The first bracket 1 and the second bracket 5 are installed on the ladder station by fixing bolts 4, which increases the safety of the brackets and also ensures the safety of the staff.

[0027] The first hanger 1 and the second hanger 5 have an S-structure, which facilitates hanging. They can be used individually or spliced ​​together as needed.

[0028] The inner middle of both protective frames 2 is welded to the first hanging frame 1 and the second hanging frame 5 by reinforcing rods 7, which increases the strength and safety of the protective frames.

[0029] The connecting rod 9 on the second bracket 5 passes through the foot platform 6 and through the first bracket 1, and a nut 10 is installed on the left end of the connecting rod 9, so that the foot platform can be more stably installed on the inner ends of the two brackets.

[0030] The upper surface of the footrest 6 is frosted, which increases the friction between the sole of the shoe and the footrest, preventing slippage.

[0031] The connecting columns 11 at both ends of the crossbeam 8 pass through the first bracket 1 and the second bracket 5 respectively and are fixed with nuts, making the connection between the first bracket and the second bracket more secure.

[0032] The crossbeam 8 has a rectangular structure, and multiple crossbeams are evenly spaced from top to bottom, which improves the safety of the hanger.

[0033] Working principle:

[0034] When using, choose to use the first bracket 1 alone or to use the first bracket 1 and the second bracket 5 together, depending on the usage requirements. Insert the connecting column 11 at the left end of the crossbeam 8 through the first bracket 1 and fix it with a nut. Then, align the second bracket 5 with the connecting column 11 at the right end of the crossbeam 8 and fix it with a nut. Then, place the foot platform 6 inside the bottom of the first bracket 1 and the second bracket 5. Then, insert the connecting rod 9 through the second bracket 5, the foot platform 6 and the first bracket 1 in sequence and fix it with a nut 10. Then, suspend the bracket at the required position and fix it with the fixing bolt 4.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
