Inserting rod slewing mechanism of window cleaning machine

Abstract

The invention provides an inserting rod slewing mechanism of a window cleaning machine. The inserting rod slewing mechanism comprises a strut and a cantilever which is arranged at the upper end of the strut, and further comprises an inclined support, wherein a triangular structure is constituted by the inclined support, the cantilever and the upper part of the strut; a fixed stand is arranged on the lower part of the strut; a circle of rotating rollers are arranged on the fixed stand; a rotary tray is welded on the periphery of the strut; the rotary tray is supported by the rotating rollers in the radial direction of the rotary tray; and a rolling bearing is arranged at the bottom of the strut for supporting the strut in a longitudinal direction. The inserting rod slewing mechanism disclosed by the invention, through the adoption of the rolling bearing on all rotating positions, can greatly enhance the convenience of operation.

Description

technical field [0001] The invention relates to a window cleaning machine, in particular to a plug-in rod rotary mechanism of the window cleaning machine. Background technique [0002] In the prior art, such as figure 1 As shown, there are two types of slewing mechanism in the form of a plunger: one is that the cantilever and the pillar have relative motion, that is, the cantilever revolves around the pillar, a sliding bearing is installed at the H point, and more than 3 bearings are installed at the M point. The rotating roller in a circle is installed on the cantilever mechanism and rotates around the pillar, that is, the roller is installed on the moving structure; the other is that the cantilever and the pillar are integrated, that is, a large steel pipe is used, and it is installed at M. There are rolling bearings, and sliding bearings are installed at L. Due to the use of integrated steel pipes and the need to withstand external load bending moments, the corresponding...

Problems solved by technology

[0002] In the existing technology, such as figure 1 As shown, there are two types of slewing mechanism in the form of a plunger: one is that the cantilever and the pillar have relative motion, that is, the cantilever revolves around the pillar, a sliding bearing is installed at the H point, and more than 3 bearings are installed at the M point. The rotating roller in a circle is installed on the cantilever mechanism and rotates around the pillar, that is, the roller is installed on the moving structure; the other is that the cantilever and the pillar are integrated, that is, a large steel pipe is used, and it is installed at M. There are rolling bearings, and sliding bearings are installed at L. Due to the use of integrated steel pipes and the need to withstand external load bending moments, the corresponding circular steel pipes have a very large diameter. The bearings in the national standard are not available or the cost is very expensive.
