[0002] When working outside the windows of buildings (for example, installing or maintaining outdoor work such as gluing the edges of aluminum alloy doors and windows), a lifting device is usually installed on the roof, and a hanging basket is hung outside the building. Workers enter the hanging basket in a suspended state to perform related work. After the construction is completed, the hanging basket is folded up to end the work.

[0041] The support frame 1 is installed on the inner side of the building, and is connected to two mounting rods 3. The mounting rods 3 extend to the outside of the building through the windows. The workbench 2 is arranged on the top of the mounting rods 3, and a guardrail assembly 4 is detachably connected to the top of the workbench 2.

[0042] Two sets of fixed sleeves 5 are arranged at the bottom of the workbench 2. Figure 5 As shown, two groups of the fixed sleeves 5 are symmetrically arranged on both sides of the workbench 2, each group of the fixed sleeves 5 includes a first sleeve 51 and a second sleeve 52, and the support frame 1 is connected to two third sleeves 6, and the two third sleeves 6 are symmetrically arranged on both sides of the support frame 1, and the axes of the first sleeve 51, the second sleeve 52 and the third sleeve 6 on the same side coincide;

[0043] The horizontal platform bracket also includes two connecting pins 7 for fixing the workbench 2, each of the connecting pins 7 is respectively inserted into the first sleeve 51, the second sleeve 52 and the third sleeve 6 located on the same side, the second sleeve 52 is connected with a first nut, the first bolt fixing the connecting pin 7 is connected to the first nut, and the first bolt passes through the first nut and the second sleeve 52 and abuts against the outer wall of the connecting pin 7.

[0044] In order to prevent the connection pin 7 from falling off from the first sleeve 51, the second sleeve 52 and the third sleeve 6 during use, the end of the connection pin 7 close to the third sleeve 6 is connected to an anti-drop rod 8, the axis of the anti-drop rod 8 is perpendicular to the axis of the connection pin 7, and the end of the connection pin 7 away from the anti-drop rod 8 is provided with a second through hole, and one end of the third bolt 9 is connected to the third nut through the second through hole. If the first bolt is loose, as the operator moves during the operation, the connection pin 7 and the first sleeve 51, the second sleeve 52 and the third sleeve 6 will slide relative to each other, and the anti-drop rod 8, the third bolt 9 and the third nut can prevent the connection pin 7 from sliding out of the first sleeve 51, the second sleeve 52 and the third sleeve 6. The anti-drop rod 8, the third bolt 9 and the third nut can improve the reliability of the connection between the workbench 2 and the mounting rod 3.

[0045] Specifically, the support frame 1 includes two vertically adjustable adjustment rods 11, a top crossbar 12, a middle crossbar 13 and a bottom crossbar 14. Figure 6 As shown, the top cross bar 12 is connected to the top of the adjusting rod 11, the middle cross bar 13 and the bottom cross bar 14 are connected to the side of the adjusting rod 11 away from the building, and the middle cross bar 13 is connected near the upper end of the adjusting rod 11, and the bottom cross bar 14 is connected near the lower end of the adjusting rod 11, and the mounting rod 3 is located between the middle cross bar 13 and the bottom cross bar 14, and the mounting rod 3 is fixedly connected to the adjusting rod 11;

[0046] The top crossbar 12, the middle crossbar 13 and the bottom crossbar 14 are connected to the adjustment rod 11 by fixing bolts, and the top crossbar 12, the middle crossbar 13 and the bottom crossbar 14 are respectively provided with a plurality of adjustment holes 15 along their respective length directions, and the fixing bolts are connected to the adjustment rod 11 through the corresponding adjustment holes 15. The plurality of adjustment holes 15 on the top crossbar 12, the middle crossbar 13 and the bottom crossbar 14 correspond to different spacings of the adjustment rods 11, so that in the present application, the widths of the two adjustment rods 11 can correspond to different window sizes.

[0047] After the distance between the two adjusting rods 11 is adjusted, the axis of the third sleeve 6 is offset from the axis of the first sleeve 51 and the second sleeve 52, resulting in the inability to fix the workbench 2 by the connecting pin 7. In order to avoid the problem that the workbench 2 cannot be fixed, each set of fixed sleeves 5 also includes a plurality of pairs of connecting sleeves 53, and each pair of connecting sleeves 53 is symmetrically arranged on the left and right sides of the workbench 2, such as Figure 5 The position of the connecting sleeve 53 corresponds to the position of the adjusting hole 15, so that after the spacing of the adjusting rod 11 changes, the third sleeve 6 can be aligned with the connecting sleeve 53, so that the connecting pin 7 can be inserted, avoiding the problem that the workbench 2 cannot be fixed.

[0048] Specifically, the length of the top cross bar 12 and the middle cross bar 13 is greater than the length of the workbench 2, and the length of the top cross bar 12 and the middle cross bar 13 is also greater than the width of the window.
