DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] The embodiment of the present application discloses a rear-tensioned anchored electric construction hanging basket.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The rear-tensioned anchored electric construction hanging basket includes a special-shaped bracket 10 arranged on the structural beam 5. The special-shaped bracket 10 includes a bottom plate 101 anchored on the structural beam 5 and a support 102 welded on the bottom plate 101. The special-shaped bracket 10 is made of Q235 material, and a horizontal arm 1 is slidably penetrated and bolted on the top of the support 102.

[0031] Reference Figure 1 , Figure 2 and Figure 3In actual construction, the top of the structural beam 5 at different positions may have different inclination angles. Therefore, multiple special-shaped brackets 10 are often equipped. Different special-shaped brackets 10 have different angles between the base plate 101 and the support 102, which is suitable for the installation of the boom 1 on the structural beam 5 with different inclination angles to ensure that the boom 1 remains in a horizontal state.

[0032] Reference Figure 1 One end of the boom 1 is mounted with a hanging box 3 through a lifting wire rope 2. The hanging box 3 is equipped with a rope winding mechanism for winding and unwinding the lifting wire rope 2, so as to realize the lifting and lowering of the hanging box 3. The rope winding mechanism directly adopts the existing technology.

[0033] Reference Figure 1 and Figure 2 The other end of the boom 1 is hinged with a U-shaped frame (not shown in the figure), and the U-shaped frame is equipped with an oblique steel wire rope 4 that is tilted downward and anchored on the structural beam 5.

[0034] Reference Figure 1 , Figure 2 and Figure 4 An anchor plate 6 is pre-buried on the structural beam 5 and fastened by anchor bolts, a U-shaped steel frame 7 is welded on the anchor plate 6, and the inclined steel wire rope 4 passes through the U-shaped steel frame 7 and is fastened by a plurality of steel wire rope clamps 8. The anchor plate 6 cooperates with the U-shaped steel frame 7 to form a stable anchor point on the structural beam 5 for the inclined steel wire rope 4 to be connected.

[0035] Reference Figure 1 , Figure 2 and Figure 4 A basket bolt 9 is arranged at the bottom of the inclined steel wire rope 4, and the basket bolt 9 realizes the secondary pre-tightening after the inclined steel wire rope 4 is connected to the U-shaped steel frame 7, further enhancing the tension of the inclined steel wire rope 4.
