Inserting rod of window cleaning machine

Abstract

The invention provides an inserting rod of a window cleaning machine. The inserting rod comprises a supporting pillar and a cantilever which is arranged at the upper end of the supporting pillar, and further comprises an inclined support, wherein a triangular structure is defined by the inclined support, the cantilever and the upper part of the supporting pillar; a fixed stand is arranged on the lower part of the supporting pillar; rotary rollers are arranged on the fixed stand; a rotary disc is welded on the peripheral side of the supporting pillar; the rotary rollers are used for supporting the rotary disc in the radial direction of the rotary disc; rolling bearings are arranged at the bottom of the supporting pillar for supporting the supporting pillar in a longitudinal direction; and both the cantilever and the supporting pillar are rectangular pipes. Since all rotary positions are in the form of the rolling bearings and since the cantilever and the supporting pillar are rectangular pipes, the operation convenience is greatly improved, and meanwhile equipment weight is greatly reduced and cost is reduced.

Description

technical field [0001] The invention relates to a window cleaning machine, in particular to an insertion rod 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 loop is installed on the cantilever mechanism and also revolves around the pillar, that is, the roller is installed on the moving structure, the cantilever adopts a rectangular tube, and the pillar is used to allow the rotating roller connected to the cantilever to rotate around it. The other is that the cantilever and the pillar are integrated, that is, a large steel pipe is used, and a rolling bearing is installed at M, and a sliding bearing is installed a...

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 loop is installed on the cantilever mechanism and also revolves around the pillar, that is, the roller is installed on the moving structure, the cantilever adopts a rectangular tube, and the pillar is used to allow the rotating roller connected to the cantilever to rotate around it. The other is that the cantilever and the pillar are integrated, that is, a large steel pipe is used, and a rolling bearing is installed at M, and a sliding bearing is installed at L. Loading force, the bending moment formed by it will be borne by the pillars, but we all know that the bending modulus of circular steel pipes is not good, and under the same bending moment, the size of circular steel pipes is much larger than that of rectangular pipes

Due to the very large diameter of the circular steel pipe, the bearings in the national standard cannot be used or the cost is very expensive
