The entire mechanism of the track type window cleaner is installed on a chassis that can walk on a horizontal track, and the horizontal operation of the entire window cleaner is completed by the movement of the walking chassis. This type of window cleaner is generally installed on a roof with a small slope, which is relatively independent from the building and has a high safety factor. Due to the flexible and diverse mechanisms of the window cleaner, such as lifting, slewing, and hoisting, the rail window cleaner can meet the requirements of most buildings. As long as sufficient space and allowable load are reserved on the roof of the building, the arm length can be changed from Several meters to tens of meters, because the weight increases with the increase of the arm, and the weight of the whole machine ranges from 2 to 3 tons to tens of tons. Therefore, the concentrated load of the window cleaner must be considered in the design of the building structure. Influence of the structure, adding necessary bearing beams and other structures to meet the necessary conditions for installing window cleaners.
The track type window cleaner is connected to the building structure through the track system, and the gauge is generally 0.8 to 2.0m. The two tracks can be set on one plane or not on one plane. The track system consists of a base, a connector and a track. The embedded part of the foundation is composed of one embedded steel plate and four φ16 anchor bolts. The embedded bolts are fixed to the embedded steel plate with nuts, and the civil unit is poured into the window cleaner base before the building structure is capped. The height should be more than 80mm above the roofing layer. After the construction of the foundation is completed, all the embedded steel plates are adjusted to the same level by adjusting the nuts on the embedded bolts. After the second grouting fills the gap, the embedded steel plates are fixed. Finally, the rails are fixed to the embedded steel plates with rail connectors (pressure plates) on. The window cleaner track uses I-shaped steel or H-shaped steel. Generally, the track is directly welded to the embedded steel plate. Due to the advantages of simple and reliable construction and smooth operation of the window cleaner, it is widely used. After the installation of the track is completed, the base and the roof are uniformly waterproofed.
