[0002] In existing high-altitude box girder track construction, the main method used is to install fixed safety devices at the construction location to protect the personal safety of workers. However, since construction along the high-altitude box girder track requires frequent movement to reach different work points, the current fixed safety devices are extremely inconvenient for frequent changes in position on the track. They cannot facilitate the movement of construction workers as the work location changes, and the construction requires more manpower and resources.

[0003] Therefore, it is necessary to propose a high-altitude work safety trolley to solve the problems existing in the current technology. Utility Model Content

[0004] The purpose of this utility model is to provide a convenient and mobile high-altitude work safety vehicle to solve the problems mentioned in the background art. The technical solution is as follows: A safety trolley for working at heights includes a carrying platform, a first moving component, a second moving component, and a fixed component; The first moving component and the second moving component are detachably mounted on the bearing platform. The first moving component is slidably mounted on the top of the track beam. There are at least two sets of the second moving component, and the two sets of the second moving component are slidably mounted on both sides of the track beam. The fixing component can abut against the track beam.

[0005] Preferably, the first moving component includes an upper shaft detachably mounted on the support platform and a front bearing roller rotatably mounted on the upper shaft. The front-facing pressure roller can also roll along the top of the track beam.
