During the final curtain wall construction stage of some buildings, window cleaning machines are used as the main construction machinery for curtain wall installation. For this kind of single-point and high-frequency use, some problem points in the original equipment design are exposed.
[0003] For example, in some upper-rotation window cleaning machines or folding-arm window cleaners, in such equipment, there are two sets of wire rope pulleys at the rotation or folding-arm positions. One set is fixed, and the other set is a pulley group that rotates around the fixed pulley group. When the center positions of these two sets of pulleys are relatively close and the positive and negative rotation angles are large, it is inevitable that the steel wire ropes will get tangled or the side of the rope groove of the pulley will be quickly worn by the steel wire ropes. Now, as a single-point and frequently used construction equipment, the service life of the pulleys and the steel wire ropes is greatly reduced. The original service life was more than 10 years, but now it needs to be replaced in 2 - 3 years.

[0035] The terms "first", "second", "third", "fourth", etc. in the description and claims of the present utility model are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence.
[0036] Embodiment 1
[0037] Figure 1 This is a plan view of the sliding variable-position anti-interference wheel group for the steel wire rope of the window cleaning machine provided by the embodiment of the present utility model, Figure 2 which is Figure 1 a cross-sectional view of the sliding variable-position anti-interference wheel group for the steel wire rope of the window cleaning machine in Figure 3 which is Figure 2 an enlarged view of part A in Figure 4 which is Figure 1 a side view of the sliding variable-position anti-interference wheel group for the steel wire rope of the window cleaning machine in. Please refer to Figure 1 、 Figure 2 、 Figure 4, the wire rope sliding displacement and anti-interference wheel set for window cleaning machines provided by the embodiments of the present utility model includes a limit turntable 1, a driven turntable 2, a fixing plate 3, a wheel frame assembly 4, a fixed pressing plate assembly 5, and a grooved copper steering wheel assembly 6; the fixing plate 3 is in the shape of a square plate, and the fixed pressing plate assemblies 5 are connected to the four corners of the fixing plate 3; a circular hole 31 is provided at the center position of the fixing plate 3; the grooved copper steering wheel assembly 6 includes a plunger screw 61, a self-lubricating flanged copper bushing 62, a self-lubricating copper flat washer 63, and a self-locking nut 64; the limit turntable 1 and the driven turntable 2 are in the shape of discs, four first through holes 11 are provided on the limit turntable 1, the four first through holes 11 are located on the same circumference, and the included angle between two adjacent first through holes 11 is 90 degrees; second through holes 21 matching the first through holes 11 are provided on the driven turntable 2, the plunger screws 61 respectively pass through the second through holes 21, the self-lubricating flanged copper bushings 62, the self-lubricating copper flat washers 63, and the first through holes 11, and are tightened on the other end of the plunger screws 61 through the self-locking nuts 64 to fix the limit turntable 1 and the driven turntable 2; a sliding groove 65 is formed between the self-lubricating flanged copper bushing 62 and the self-lubricating copper flat washer 63, and the sliding groove 65 is rotatably engaged with the edge of the circular hole 31; the wheel frame assemblies 4 are installed at the center positions of the limit turntable 1 and the driven turntable 2, and the two wheel frame assemblies 4 are symmetrical about the fixing plate 3.
[0038] It should be noted that the design of the sliding groove 65 on the grooved copper steering wheel assembly 6 enables the limit turntable 1 and the driven turntable 2 to freely rotate circumferentially around the edge of the circular hole 31, thereby driving the wheel frame assembly 4 to freely rotate. Further prevent the limit turntable 1 and the driven turntable 2 from falling off the fixing plate 3, and moreover, the rotation speed here is not fast and the force is small, so standard parts are used in the design, reducing the manufacturing cost and improving the component accuracy.
[0039] Figure 9 For Figure 1 the schematic diagram of the use of the wire rope sliding displacement and anti-interference wheel set for window cleaning machines. Please refer to Figure 9 , when there are two sets of wire rope pulleys in the window cleaning machine equipment, one set is a fixed-position wire guiding pulley 100, and the other set is a rotating-position wire guiding pulley 9 that rotates around the fixed pulley 100, and the center positions of the two sets of pulleys are relatively close, and the positive and negative rotation angles are large (for example: the wire rope pulley at the rope outlet of the hoisting mechanism of the upper-rotation window cleaning machine and the wire rope pulley at the head of the inner guiding arm of the boom. Since it is an upper-rotation equipment, the water outlet pulley of the hoisting mechanism is fixed, and the wire rope pulley at the head of the inner guiding arm of the boom rotates with the boom), then in order to prevent the wire rope 8 from getting entangled or the wire rope 8 from quickly wearing the side of the pulley rope groove, it is necessary to install the wire rope sliding displacement and anti-interference wheel set of the present utility model.
[0040] When in use, first change the appearance of the fixed plate 3 according to the size of the square hole of the internal reinforcing rib plate (there will be a reinforcing rib plate in the frame structure of the window cleaning machine equipment) (generally 20mm longer than the side length of the square hole of the reinforcing rib plate), select the reinforcing rib plate basically close to the middle position of the upper and lower wheel groups, and fix it with the fixed pressure plate assembly 5. In this way, the fixing work of the whole wheel group is completed; pass the wire rope 8 from the fixed position guide rope wheel 100, and pass through the wheel frame assembly 4 on the limiting turntable 1 in turn, pass through the wheel frame assembly 4 of the driven turntable 2, and finally enter the rotating position guide rope wheel 9 that needs to be rotated.
[0041] The utility model discloses a window cleaning machine wire rope sliding displacement rotation anti-interference wheel group, which solves the fundamental reason that when there are two sets of corresponding pulley groups inside the window cleaning machine, one set is fixed and the other set is in a rotating working state around the fixed pulley group, and the two sets of pulleys have large positive and negative rotation angles and small center distances, the wire rope may be tangled and the wire rope and the side surfaces of the rope groove of the rope wheel may wear quickly. This problem is effectively solved through the principle of simple mechanical transmission structure. The pulley group in special position has a simple and compact structure and high safety performance, which greatly improves the service life of the window cleaning machine components and reduces the operation and maintenance costs of the window cleaning machine.
[0042] Figure 5 for Figure 1 Front view of the wheel frame assembly of the wire rope sliding displacement anti-interference wheel set of the central window cleaning machine, Figure 6 for Figure 1 Cross-sectional diagram of the wheel frame assembly of the wire rope sliding displacement anti-interference wheel set of the central window cleaning machine. Please refer to Figure 5 , Figure 6 The wheel frame assembly 4 of the utility model includes a wheel frame vertical plate 41, a wheel axle 42, a steering wheel 43, a bearing 44 and a locking nut 45; the wheel frame vertical plate 41 includes a base plate 411 and a support plate 412, the base plate 411 and the support plate 412 are vertically connected, two mounting holes 413 are arranged on the support plate 412, the wheel axle 42 is inserted into the two mounting holes 413, a plurality of bearings 44 are sleeved on the wheel axle 42, the steering wheel 43 is sleeved on the bearing 44, and another support plate 412 is passed through the mounting hole 413 at the other end of the wheel axle 42 and locked by the locking nut 45.
[0043] It should be noted that each of the steering wheels 43 is equipped with a bearing 44, so that they can rotate freely and independently, effectively preventing the diameters of the rope grooves of each wheel and the tangent position of the wire rope 8 from being different during the rotation process, thereby causing wear due to the speed difference, and because the spacing between the two sets of steering wheels 43 is small, the risk of the wire rope 8 escaping from the rope groove is prevented.
[0044] Figure 7 for Figure 1Top view schematic diagram of the wheel frame assembly of the anti-interference wheel set for the sliding displacement rotation of the wire rope of the window cleaning machine Figure 8 is Figure 1 Top view schematic diagram of the anti-interference wheel set for the sliding displacement rotation of the wire rope of the window cleaning machine. Please refer to 7 Figure 8 In the present utility model, a sector-shaped waist hole 414 is provided on the bottom plate 411, and two said wheel frame assemblies 4 are respectively fixed on the limit turntable 1 and the driven turntable 2 by bolts 415 passing through the sector-shaped waist hole 414; further, the axis of the sector-shaped waist hole 414 is the same as the axis of the round hole 31.
[0045] It should be noted that the design that the axis of the sector-shaped waist hole 414 is the same as the axis of the round hole 31 enables the fixing plate 3 and the upper and lower wheel frame assemblies 4 to be pre-adjusted and fixed in angle when encountering a window cleaning machine with a relatively large single-sided rotation angle, improving the adaptability to a large single-sided angle. This special-position pulley group has a simple, compact structure and high safety performance, meeting the requirements of pulley groups with large positive and negative rotation angles.
[0046] Further referring to Figure 8 、 Figure 9 The anti-interference wheel set for the sliding displacement rotation of the wire rope of the window cleaning machine of the present utility model further includes corner limit screws 7. A plurality of screw holes 32 cooperating with the corner limit screws 7 are provided on the fixing plate 3 on the side away from the limit turntable 1, and the plurality of screw holes 32 are located on the same circumference; two said corner limit screws 7 are installed in the corresponding screw holes 32, and a limit protrusion 12 is provided on the circumference of the limit turntable 1; when the limit protrusion 12 on the limit turntable 1 rotates to the position where the corner limit screw 7 is located, the corner limit screw 7 will limit the rotation of the limit turntable 1. Specifically, 12 said screw holes 32 are provided on the fixing plate 3, and the included angle between adjacent screw holes 32 is 30 degrees.
[0047] It should be noted that two installed corner limit screws 7 are used to solve the problem of how many angles of auxiliary rotation are required (when setting, taking the center position of the required positive and negative rotation angles as the center point, deflecting 1 / 2 angle to the left and right respectively. For example, if it is required to deflect ±90°, then the included angle of the two corner limit screws 7 at this time during setting is ±45°). When the rotation angle center points of the fixed-position guide rope wheel 100 and the rotating-position guide rope wheel 9 are determined, the corner limit screws 7 are screwed on at the corner points to be controlled respectively.
[0048] Based on the above description, the advantages of the present utility model are as follows:
[0049] The wire rope sliding displacement and anti-interference pulley group of the window cleaning machine of the utility model solves the root cause that inside the window cleaning machine, when two corresponding pulley groups, one is fixed and the other rotates around the fixed pulley group, and the positive and negative rotation angles of these two groups of pulleys are large and the center distance is small, resulting in wire rope entanglement and rapid wear on the side of the wire rope and the rope groove of the rope pulley. This problem point is effectively solved through the principle of simple mechanical transmission structure. This special-position pulley group has a simple, compact structure and high safety performance, greatly improving the service life of the components of the window cleaning machine and reducing the operation and maintenance costs of the window cleaning machine.
[0050] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
