[0031] It should be noted that the fixed rod 32 and the opposite side of the electric push rod 5 are both hingedly connected to the limit rod through a hinge seat to form a triangular stable support, providing a suspended support force for the outward-extending side of the suspension beam 1 to prevent bending.

[0032] See also Figures 2 to 3 In order to facilitate the adjustment of the position of the left support mechanism 3, the adjustment mechanism 4 in this embodiment includes a driving motor 42, two threaded rods 43, two rotating gears 44, two screw sleeves 45, two mounting plates 46 and a sliding seat 47. A placement cavity 41 is provided at the right end of the inner cavity of the reinforcement frame 2, and the driving motor 42 is fixed in the inner cavity of the placement cavity 41. A receiving hole 48 is provided on the front side of the reinforcement frame 2.

Start the driving motor 42, and the output shaft of the driving motor 42 rotates to drive the front threaded rod 43 to rotate. The rotation of the front threaded rod 43 can drive the rotating gear 44 fixed on its surface to rotate, and the rotation of the front rotating gear 44 can cause the rear rotating gear 44 meshing with it to rotate.

[0033] The rotating gear 44 is fixed to the right end of the outer surface of the threaded rod 43, the screw sleeve 45 is threadedly connected to the threaded rod 43, and the two mounting plates 46 are fixed on the opposite sides of the two screw sleeves 45. The rotation of the two threaded rods 43 causes the screw sleeves 45 threadedly connected to their surfaces to move, and the movement of the screw sleeves 45 drives the movement of the mounting plate 46. The sliding seat 47 is provided on the outer surface of the reinforcement frame 2. The movement of the mounting plate 46 can make the sliding seat 47 move horizontally on the outer surface of the reinforcement frame 2, so that the position of the left support mechanism 3 can be adjusted.

[0034] In this embodiment, a fixing plate is fixed to the upper surface of the reinforcement frame 2 and the sliding seat 47, and a guide wheel is rotatably installed on the upper surface of the fixing plate. The output shaft of the drive motor 42 passes through the placement cavity 41 and extends to the inner cavity of the accommodating hole 48 and is fixed to the front threaded rod 43, and the two rotating gears 44 are engaged and connected.

[0035] Among them, a connecting plate is fixed between the opposite sides of the two screw sleeves 45, and the opposite sides of the two mounting plates 46 are fixed to the sliding seat 47. The sliding seat 47 is in the shape of a rectangular parallelepiped with a hollow interior and missing left and right sides. Slide grooves are provided on the upper and lower sides of the reinforcement frame 2, and sliders are fixed on the inner top wall and the inner bottom wall of the sliding seat 47.

[0036] It should be noted that the provided adjustment mechanism 4 can adjust the position of the left support mechanism 3, thereby adjusting the suspended lateral distance without the need for fixing or disassembling with the aid of tools, which greatly improves the adjustment efficiency of the staff.

[0037] See also Figure 4 In order to adapt to the tops of high-rise buildings of different heights, the support mechanism 3 in this embodiment includes a base 31, a fixing rod 32, an inner screw 33, a sleeve 34, a driven bevel gear 35, a driving bevel gear 36 and an outer screw 37. The base 31 is arranged on the lower side of the suspension beam 1 and the reinforcement frame 2, the fixing rod 32 is fixed to the upper surface of the base 31, the inner screw 33 is arranged in the inner cavity of the fixing rod 32, and the sleeve 34 is fixed to the bottom of the inner cavity of the inner screw 33. The rotation of the sleeve 34 drives the inner screw 33 to rotate, and the lower surface of the sleeve 34 The driven bevel gear 35 is rotatably connected to the inner bottom wall of the fixed rod 32 through a bearing. The driven bevel gear 35 is fixed to the outer surface of the sleeve 34. The driving bevel gear 36 is meshed and connected to the right side of the driven bevel gear 35. The rotation of the driving bevel gear 36 causes the driven bevel gear 35 meshed with it to rotate. The rotation of the driven bevel gear 35 causes the sleeve 34 fixed in its inner cavity to rotate. The outer screw 37 is threadedly connected to the inner cavity of the inner screw 33. The rotation of the inner screw 33 causes the outer screw 37 threadedly connected to its inner cavity to move upward.

[0038] In this embodiment, the shape of the fixed rod 32 is a rectangular parallelepiped with a hollow interior and a missing upper surface. Three annular grooves are opened on the inner wall of the fixed rod 32, and three annular blocks are fixed on the outer surface of the inner screw 33. The annular blocks make horizontal circular motion in the inner cavity of the annular grooves. When the inner screw 33 rotates, the three annular blocks fixed on its outer surface rotate in the inner cavity of the three annular grooves opened in the inner cavity of the fixed rod 32, which can limit the rotation of the inner screw 33.

[0039] Among them, a rotating rod is fixed to the inner cavity of the active bevel gear 36, and the right side of the rotating rod passes through the fixed rod 32 and extends to the right side of the fixed rod 32. The upper surface of the outer screw 37 is fixed to the sliding seat 47 and the suspension beam 1, and a triangular column is fixed to the upper surface of the sleeve 34. The inner cavity of the outer screw 37 is provided with a triangular groove that is adapted to the size of the triangular column. The set triangular column can limit the movement of the outer screw 37 so that it can only perform linear up and down motion.

[0040] It should be noted that the movement of the outer screw 37 increases the height of the suspension beam 1 and the reinforcement frame 2, so that they can adapt to the tops of high-rise buildings of different heights, thereby improving the applicability and flexibility of the cleaning bracket.

[0041] The working principle of the above embodiment is:

[0042] (1) When adjusting the horizontal position of the left support mechanism 3, first fix the base 31 in the right support mechanism 3 to the ground at the top of the high-rise building by bolts, then start the drive motor 42, and the output shaft of the drive motor 42 rotates to drive the front threaded rod 43 to rotate. The rotation of the front threaded rod 43 can drive the rotating gear 44 fixed on its surface to rotate, and the rotation of the front rotating gear 44 can cause the rear rotating gear 44 meshed with it to rotate, so that the rotation of the two threaded rods 43 causes the screw sleeve 45 threadedly connected to its surface to move, and the movement of the screw sleeve 45 drives the movement of the mounting plate 46. The movement of the mounting plate 46 can cause the sliding seat 47 to move horizontally on the outer surface of the reinforcement frame 2, so that the position of the left support mechanism 3 can be adjusted. Finally, fix the base 31 in the left support mechanism 3 to the ground at the top of the high-rise building by bolts.

[0043] (2) In order to adapt to the ground at the top of high-rise buildings of different heights, the rotating rod can be rotated. The rotation of the rotating rod drives the active bevel gear 36 to rotate. The rotation of the active bevel gear 36 causes the driven bevel gear 35 meshing with it to rotate. The rotation of the driven bevel gear 35 causes the sleeve 34 fixed in its inner cavity to rotate. The rotation of the sleeve 34 drives the inner screw 33 to rotate. When the inner screw 33 rotates, the three annular blocks fixed on its outer surface rotate in the inner cavity of the three annular grooves opened in the inner cavity of the fixed rod 32, which can limit the rotation of the inner screw 33. The rotation of the inner screw 33 causes the outer screw 37 threadedly connected to its inner cavity to move upward. At this time, due to the limiting effect of the triangular column, the outer screw 37 can only move linearly. The movement of the outer screw 37 increases the height of the cantilever beam 1 and the reinforcement frame 2, so that it can adapt to the top of high-rise buildings of different heights.
