[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figures 1-5 As shown, a high-altitude operation device includes a bottom support mechanism 1, a vertical support mechanism 2, and a construction platform 3.

[0019] The bottom support mechanism 1 is a base structure for ground support. The vertical support mechanism 2 is installed on the bottom support mechanism 1 and can be pre-adjusted according to the construction height. The construction platform 3 is installed on top of the vertical support mechanism 2 and can be adjusted laterally according to the construction position requirements. The high-altitude operation device of this embodiment can be adjusted and combined according to actual construction needs, and has the advantages of small footprint and good stability. It is suitable for high-speed railway station rain shelter maintenance projects or similar projects with limited space.

[0020] Please refer to 1. Figure 3 and Figure 4 The bottom support mechanism 1 includes a base and an outer support member 11. The base has four installation areas, each with a bracket connection part 14 for bracket installation and connection. Each installation area also has an outer support member 11. Vertical support legs 13 are provided on the base and in the areas where the outer support member 11 extends beyond the base. The vertical support legs 13 are vertically adjustable. The vertical support legs 13 can also be vertically set hydraulic support legs. After the bottom support mechanism 1 is installed in the installation position, the vertical support legs 13 on each base and the vertical support legs 13 on each outer support member 11 are vertically adjusted. Each vertical support leg 13 supports the ground and cooperates to lift the base. The entire device is supported by multiple vertical support legs 13, which can ensure the stability of the device during construction.

[0021] The base is preferably a rectangular frame structure, with four mounting areas located at the four corners of the base. As a specific example, the base includes two bottom beams 12 arranged parallel to each other. There are two or more bottom connecting rods, with each end connected to one of the two bottom beams 12. The two bottom beams 12 are connected by at least two bottom connecting rods to form a rectangular frame structure. Each bottom beam 12 has mounting areas at both ends.

[0022] A support sleeve is provided on the bottom beam 12 at the installation area. The support sleeve is horizontally set and used to install the outer support member 11. The outer support member 11 is a rod with a cross-sectional shape corresponding to the inner contour of the support sleeve. The outer support member 11 passes through the support sleeve and can move and adjust along the support sleeve. The support sleeve is also provided with a threaded hole, which communicates with the internal space of the support sleeve. A fastening screw is provided in the threaded hole. After the outer support member 11 moves and is aligned relative to the support sleeve, the fastening screw is rotated and the end of the fastening screw is pressed against the outer support member 11, thereby fixing the outer support member 11.

[0023] In a further embodiment, each installation area is provided with a first sleeve 15 and a second sleeve 16. Both the first sleeve 15 and the second sleeve 16 are the aforementioned support sleeves. The first sleeve 15 is parallel to the bottom beam 12, and the second sleeve 16 is perpendicular to the bottom beam 12. An external support member 11 is provided inside the first sleeve 15 and / or the second sleeve 16. In an even further embodiment, there are two second sleeves 16, each of which is directly connected to the bottom beam 12. The first sleeve 15 is positioned above the second sleeves 16 and connected to each of the second sleeves 16.

[0024] Each external support 11 can be moved and adjusted horizontally relative to the base. When the construction height is low or the construction site is small, the external support 11 can extend a shorter length beyond the base. When the construction height is high or the construction site is reorganized, the external support 11 can extend a longer length beyond the base to ensure a stable support effect. Moreover, when the construction height is high, more external support 11 can be set to ensure a sufficiently stable support effect.

[0025] In some embodiments, for ease of handling and movement, the lower end face of the base beam 12 is provided with wheels 17. When the device is in the construction state, each vertical support leg 13 cooperates to lift the base and suspend the wheels 17 in the air.

[0026] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The vertical installation mechanism includes a top frame 21 and at least one bracket. The bracket includes a support rod 23 and four support legs 22. The support rod 23 has a vertically arranged insertion part at both ends. The insertion part is a short rod. The two insertion parts on the same support rod 23 are on the same side of the support rod 23 and are parallel to each other. Each support leg 22 is provided with at least two insertion tubes suitable for the insertion parts to be inserted and matched. When two support legs 22 are arranged parallel to each other, the two insertion parts of the support rod 23 respectively match the insertion tubes on the two support legs 22 and can connect the two support legs 22. When all four support legs 22 are arranged vertically and distributed in a rectangular four-corner distribution, the four support rods 23 connect the four support legs 22 in sequence to form a frame structure.

[0027] In a preferred embodiment, the four support poles 23 or two support poles 23 in opposite directions are set at the same height to facilitate the installation of scaffold boards on the scaffold. More sets of inserts can also be installed on each support leg 22 to allow for the installation of more sets of support poles 23 on the scaffold, thereby enabling the installation of multiple layers of scaffold boards. These multiple layers of scaffold boards can also be used as ladders, facilitating personnel to climb to or descend from the construction platform 3 above to the ground.

[0028] Each support leg 22 has a bracket connecting part 14 at its top and at each mounting area on the base. The bracket connecting part 14 is a vertically arranged sleeve, and each sleeve has a connecting hole on its wall. When there is one bracket, the bottom end of each support leg 22 of the bracket extends into the bracket connecting part 14 on the base, and each leg is connected to the corresponding bracket connecting part 14. When there are two or more brackets, the bottom end of each support leg 22 of the lowest layer bracket extends into the corresponding bracket connecting part 14 on the base and is connected to the corresponding bracket connecting part 14. The bottom end of each support leg 22 of the upper layer bracket extends into the bracket connecting part 14 at the top of the support leg 22 of the adjacent layer bracket below. The layers of brackets are stacked and connected in sequence. The bottom of the top frame 21 is provided with a vertical connecting pipe, and each connecting pipe of the top frame 21 is inserted into and connected to the bracket connecting part 14 of the uppermost layer bracket.

[0029] In some embodiments, each support leg 22 has a mating hole near the bottom and on each connecting pipe of the top frame 21. When the support leg 22 and the connecting pipe are inserted into the corresponding bracket connecting part 14, the mating hole corresponds to the connecting hole on the bracket connecting part 14. At this time, inserting a locking pin, screw, or other component can stably connect the support leg 22, the connecting pipe, and the corresponding bracket connecting part 14. In other embodiments, the connecting hole is a threaded hole and a screw is installed in the threaded hole. When the support leg 22 and the connecting pipe are inserted into the bracket connecting part 14, the screw is rotated and the screw abuts and presses against the corresponding support leg 22 or connecting pipe, thereby achieving a stable connection between the support leg 22, the connecting pipe, and the corresponding bracket connecting part 14.

[0030] According to the actual construction requirements, an appropriate number of supports can be installed on the bottom support mechanism 1. With the stable support effect of the bottom support mechanism 1, the operation requirements of the high-speed railway station rain shelter maintenance project or similar projects with limited space can be met.

[0031] Please see Figure 1 and Figure 2 The construction platform 3 includes a lower platform and an upper platform.

After the upper cross brace 33 is adjusted to the corresponding position, the lug connecting part of the upper cross brace 33 is connected to the connecting lug 32 of the lower cross brace 31 to connect the upper cross brace 33 and the lower cross brace 31. The platform plate 34 is supported and installed by the cooperation of each upper cross brace 33 of the upper platform.

[0032] The lower cross brace 31 has at least two connecting lugs 32 axially arranged on both opposite sides. Each connecting lug 32 defines a guide channel on the upper end face of the lower cross brace 31, suitable for the movement of the upper cross brace 33. Each lug connecting part and each connecting lug 32 is provided with holes. The lug connecting part and the connecting lug 32 can be connected by connecting parts such as bolts passing through the holes on the lug connecting parts and the corresponding connecting lug 32.

[0033] At least one end of the upper cross brace 33 extends to the outside of the lower cross brace 31, allowing the upper platform to extend to the outside of the vertical support mechanism 2, thereby increasing the working area of ​​the device.

[0034] In some embodiments, the upper platform includes two upper horizontal supports 33 and at least two top connecting rods. The two ends of each top connecting rod are connected to the two upper horizontal supports 33 respectively.
