Abstract
Description
Technical Field
[0001] The utility model relates to a component for a folding-arm window cleaning machine, in particular to a split-rope pulley device for a folding-arm window cleaning machine. Background Art
[0002] When the working and stopping angles of the folding arms of the existing folding-arm window cleaning machine are greater than 120 degrees, the steel wire ropes of the window cleaning machine will interfere with each other, thus affecting the normal operation of the window cleaning machine. Utility Model Content
[0003] The utility model provides a rope splitting pulley device for a folding-arm window cleaning machine.
[0004] The utility model aims to solve the problem that when the working and stopping angles of the folding arms of the existing folding-arm window cleaning machine are greater than 120 degrees, the steel wire ropes of the window cleaning machine will interfere with each other, thus affecting the normal operation of the window cleaning machine.
[0005] The utility model solves the technical problem by adopting the following technical solution: a rope splitting pulley device for a folding arm window cleaning machine, comprising a pulley frame, a pulley mounted on the pulley frame, the pulley frame being arranged on a chassis, the chassis being arranged on a bracket, and a rolling bearing being arranged under the chassis.
[0006] Preferably, there are two pulleys, which are arranged parallel to each other on the pulley frame.
[0007] Preferably, the chassis comprises a disc and a round tube, the disc is arranged on the upper part of the round tube, the round tube is arranged on a bracket, and the pulley is mounted on the disc.
[0008] Preferably, at least one bracket is provided below the disc, a rolling bearing is provided on the bracket, and an outer ring of the rolling bearing is attached to the bracket.
[0009] Preferably, a bearing is provided in the middle of the bracket, and the round tube is installed on the inner ring of the bearing.
[0010] The beneficial effect of the utility model is that the utility model can avoid mutual interference of steel wires when the folding arm window cleaning machine is working, and is particularly suitable for avoiding mutual interference of steel wires when the folding arm window cleaning machine is working at a large folding angle (the parking angle is greater than 120 degrees). BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a structural schematic diagram of the utility model.
[0012] Figure 2 This is a schematic diagram of the structure of the front side of the utility model (excluding the bracket).
[0013] Figure 3 This is a schematic diagram of the structure of the side surface of the utility model (excluding the bracket). DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] As shown in the figure, a rope splitting pulley device for a folding-arm window cleaning machine described in the utility model includes a pulley frame 6, a pulley 4 and a pulley 5 installed on the pulley frame 6, the pulley frame 6 is arranged on a chassis, the chassis is arranged on a bracket 1, and rolling bearings 2, 7 and 9 are arranged under the chassis.
[0016] The pulley 4 and the pulley 5 are arranged on the pulley frame 6 in parallel with each other.
[0017] The chassis includes a disc 3 and a round tube 8. The disc 3 is arranged on the upper part of the round tube 8. The round tube 8 is arranged on the bracket 1. The pulley is mounted on the disc. Brackets 31, 32 and 33 are arranged below the disc 3. The brackets 31, 32 and 33 are respectively provided with rolling bearings 2, 7 and 9. The outer rings of the rolling bearings 2, 7 and 9 are attached to the bracket. A bearing (not shown in the figure) is arranged in the middle of the bracket 1. The round tube 8 is installed on the inner ring of the bearing.
[0018] The working principle of the utility model is that when the steel wire rope of the folding arm of the folding arm window cleaning machine rotates, it will drive the pulley frame 6 and the chassis to rotate, thereby avoiding the mutual interference of the steel wire ropes. Therefore, the folding arm of the utility model uses a rope separation pulley device to separate the steel wire ropes, thereby avoiding the mutual interference of the steel wire ropes when the arm is folded at a large angle.
