It can be understood that, in the positioning device provided by the utility model, the driving component 22 is movably connected with the swing arm component 21 by arranging the driving component 22 on the positioning body 10. Adopt drive unit 22 to replace the rope to pull in order to adjust the swing angle of maintenance platform, adjustment efficiency is higher, and in the adjustment process, the rocking of maintenance platform is less, can avoid maintenance platform and the collision of being detected thing.

When the swing angle of the swing arm part 21 relative to the positioning body 10 needs to be adjusted, and thus the swing angle of the positioning body 10 relative to the object to be positioned (such as a tower wall), the driving part 22 arranged on the positioning body 10 works to drive the swing arm part 21 to swing, and thus the swing angle of the positioning body 10 relative to the object to be positioned is adjusted.

As shown in fig. 1, the swing assembly 20 further includes a mounting component 23, the mounting component 23 is disposed between the positioning body 10 and the swing arm component 21, the mounting component 23 is fixedly connected with the swing arm component 21, and the mounting component 23 is movably connected with the positioning body 10. The driving part 22 is movably connected to the mounting part 23.

That is, an intermediate connecting part, namely, a mounting part 23 is arranged between the positioning body 10 and the swing arm part 21, and the positioning body 10 and the swing arm part 21 are indirectly connected through the mounting part 23, so that the disassembly and the assembly between the positioning body 10 and the swing arm part 21 are convenient, and the overall stability of the positioning device structure can be improved.

In addition, the swing arm part 21 and the positioning body 10 may be directly connected, for example, an extension portion having a structure adapted to that of the mounting part 23 is formed on the side of the swing arm part 21 facing the positioning body 10 by extending the swing arm part 21, and the swing arm part 21 is movably connected with the positioning body 10 through the extension portion, that is, the mounting part 23 and the swing arm part 21 are integrally formed, and the extension portion is provided to ensure sufficient moving space between the swing arm part 21 and the positioning body 10.

When the positioning device is used for a long time and the mounting part 23 is worn to influence the use and needs to be replaced, the mounting part 23 is only required to be detached from between the positioning body 10 and the swing arm part 21, and a new mounting part 23 is replaced, so that the operation is convenient.

Compared with the direct connection of the swing arm part 21 and the positioning body 10, the installation part 23 is adopted to indirectly connect the swing arm part 21 and the positioning body 10, so that the positioning device is more convenient to detach and replace, and meanwhile, the installation part 23 is replaced without influencing the structural installation of the swing arm part 21, so that the operation is more convenient.

Specifically, as shown in fig. 2, the mounting member 23 includes a mounting body 231 and a connecting body 232, the mounting body 231 is a plate-like member or a channel steel member extending in the longitudinal direction of the swing arm member 21, and the mounting body 231 is fixedly connected to the swing arm member 21.

The mounting body 231 has a first side and a second side which are oppositely arranged along the height direction of the mounting body 231, the first side and the second side of the mounting body 231 respectively extend towards the direction where the positioning body 10 is located to form a connecting body 232, a connecting hole 2321 is formed in the connecting body 232 in a penetrating manner, and the connecting body 232 is rotatably connected with the positioning body 10 through the connecting hole 2321 in a penetrating manner through a rotating shaft, a pin shaft and other parts.
