Cross-arm double telescopic mechanism of window cleaning machine

Abstract

The invention relates to a machine for wiping windows on the outer wall of a building, in particular to a double telescopic mechanism of a cross arm of a window cleaning machine. According to the technical solution provided by the present invention, the cross-arm double-telescopic mechanism of the window cleaning machine includes a hollow fixed arm, which is characterized in that: the first telescopic arm is connected in the fixed arm, and the first telescopic arm is connected in the first telescopic arm. A telescopic second telescopic arm; a first drive mechanism is set at the end of the fixed arm close to the first telescopic arm, a first gear is set at the power output end of the first drive mechanism, and a first gear is set on the first telescopic arm The first rack, the first gear meshes with the first rack; a second drive mechanism is arranged at the end of the first telescopic arm close to the second telescopic arm, and the power output end of the second drive mechanism is provided with the first Two gears, a second rack is arranged on the second telescopic arm, and the second gear meshes with the second rack. The invention can facilitate the use of the window cleaning machine.

Description

technical field [0001] The invention relates to a machine for wiping windows on the outer wall of a building, in particular to a double telescopic mechanism of a cross arm of a window cleaning machine. Background technique [0002] Window cleaning machines are mainly used in the decoration and cleaning of the exterior walls of high-rise buildings. For buildings with complex roof structures and the window cleaning machines are far away from the exterior walls, the cross arm of the window cleaning machine must be made longer. If it encounters arcs or other changes If the external wall is damaged, the extension distance of the cross arm cannot be changed, and the size of this change puts forward new requirements for the expansion and contraction of the cross arm, and the current window cleaning machine cannot meet the needs of users. Contents of the invention [0003] The purpose of the present invention is to design a cross-arm double telescopic mechanism of the window clean...
