[0040] Embodiment 1

[0041] Please refer to Figures 1-7 An adjustable front support rear pull knot hanging basket, comprising: a support column 102 mounted on a building roof concrete beam 101, and a support beam 103 horizontally arranged on the support column 102; a pulley 104 is arranged at one end of the support beam 103 close to the building facade; a hoisting steel wire 105, one end connected to a power source, the other end connected to a hanging basket 106 through the pulley 104; the other end of the support beam 103 is provided with a counterweight steel wire assembly 200; wherein one end of the counterweight steel wire assembly 200 is connected with the support beam 103, and the other end is detachably connected with a building steel structure beam 107 located below the concrete beam 101.

[0042] In the above embodiment, first, the support column 102 is stably installed on the building roof concrete beam 101, and the support column 102 provides vertical support for the horizontally arranged support beam 103, realizes the positioning of the support beam 103 on the roof, and then the pulley 104 is assembled on one end of the support beam 103 close to the building facade, and the force direction of the hoisting steel wire 105 is changed by using the guiding effect of the pulley 104, to ensure that the driving force output by the power source can be stably transmitted to the hanging basket 106. One end of the hoisting steel wire 105 is connected to the power source, such as an electric hoist 106 lifting machine, to establish a power connection, and the other end is vertically extended to the lower side of the building facade after being turned by the pulley 104, and is fixed with the hanging basket 106 to form a complete lifting transmission path. The start and stop of the power source controls the up and down movement of the hanging basket 106.

[0043] The counterweight steel wire assembly 200 is connected to one end of the support beam 103 away from the building facade, and the other end is locked with the building steel structure beam 107 below the concrete beam 101 in a detachable manner, and the stable bearing capacity of the building steel structure beam 107 provides a counteracting force to the support beam 103, which offsets the overturning moment generated by the hanging basket 106 and the working load on the support beam 103, and realizes the force balance of the hoisting system.

[0044] Compared with the rigid counterweight structure of the traditional steel rod and counterweight block, through the flexible connection of the counterweight steel wire assembly 200, it is not necessary to rely on the length limitation of the steel rod to adapt to the space, and it is not necessary to stack the counterweight blocks. When installing, only the detachable fixing of the steel wire assembly and the steel structure beam 107 needs to be completed, and the stable counterweight effect can be quickly formed.

[0045] Adapt to the structural layout difference of different building roofs, wider application range, and the detachable connection simplifies the installation process, without the need to carry and stack a large number of counterweight blocks, the fixing of the counterweight steel wire assembly 200 and the steel structure beam 107 can be quickly completed, which greatly reduces the construction strength and improves the installation efficiency.

[0046] The traditional steel rod counterweight is easy to produce stress concentration when the rigid connection is subjected to outdoor wind vibration and load change, and is easy to deform and lose stability after long-term use. The counterweight block is easy to loosen and fall off, while the counterweight steel wire assembly 200 can absorb vibration energy through flexible connection, reduce the stress impact of the hoisting beam and the hoisting column, and reduce the fatigue damage risk of the overall structure. At the same time, the stable bearing capacity of the building steel structure beam 107 is used to replace the counterweight block, which avoids the counterweight failure problem caused by the loss and displacement of the counterweight block, and cooperates with the high strength characteristics of the steel wire itself, which further improves the operation reliability of the hoisting system.

[0047] Without relying on the rigid support of steel rods, the counterweight steel wire assembly 200 can flexibly bypass other structural components of the roof, adapt to complex roof environments, and be detachably connected to facilitate position adjustment during construction and post-maintenance, while avoiding the safety hazards of high-altitude falling during traditional counterweight installation, balancing construction safety and maintenance convenience.

[0048] Embodiment 2

[0050] In the above embodiment, one end of each group of steel wire bodies 210 is fixed to the support beam 103, and the other end is connected to the steel structure beam 107 in a V-shaped distribution structure. During operation, the V-shaped layout resolves the overturning moment of the support beam 103 through the tension of the two steel wire bodies 210 on both sides, and uniformly transmits the load to the steel structure beam 107 using the stability of the triangle force, avoiding stress concentration on a single steel wire.

[0051] The V-shaped structure improves the lateral displacement resistance compared to a single steel wire, can offset the sway caused by wind, and reduces the risk of deformation of the support beam 103. The two groups of steel wires are arranged in a spaced manner to avoid mutual friction and wear, and are suitable for different space layouts in combination with the flexibility of the steel wire. The installation does not require a counterweight block, which simplifies the operation and improves the reliability, further optimizing the stability and safety of the hoisting system.

In work, the first fixing rod 241 is fixed with the steel wire body 210 through the connecting plate 248, and the L-shaped structure can be directly hung on the steel structure beam 107. The steel wire body 210 is rotated and tightened by means of the basket bolt 220, and the positioning and fixing of the hook and the steel structure beam 107 are preliminarily completed. No additional fasteners are needed, and the initial installation process is greatly simplified. In order to avoid the shaking and wear caused by environmental factors, the second fixing rod 242 is rotated around the hinge point of the hinge plate 246 and the first opening 245 after positioning, so that the inner wall of the second fixing rod 242 abuts against the outer wall of the steel structure beam 107.
