DETAILED DESCRIPTION

[0031] Example 1:

[0032] As Figure 1 , take 400mm inner height and 4 pieces of 400mm equal length ∠5 angle steel, weld the angle steel 6 and the gravity adjustment counterweight 5; take appropriate filler to fill in the hollow box of the counterweight, ensure the filling to be dense, prevent the filler from sliding and the gravity from deviating laterally, so as to overturn the hanging basket; the bottom gravity adjustment counterweight and the upper safety hanging basket are connected by the flexible rod 4, and the flexible rod 4 is connected with the outer frame 1 by the first hinged seat 601 and the second hinged seat 606. Figure 2The connection is fixed; the arc-shaped horizontal protective net 4 is made of soft metal, which is made into a soft metal cable net and reliably connected to the rectangular rigid horizontal protective net 3. When the protective net is fully extended, it can provide complete protection for the personnel-carrying basket. The outermost ring of the overall horizontal protective net structure is wrapped with a soft foam or rubber protective strip to prevent the basket structure from colliding with the construction building and causing the construction object to suffer metal scratches and cosmetic damage. The horizontal protective nets 3 and 4 are reliably connected to the safety basket guardrail 1 through the connecting chain 5. In addition to increasing the load-bearing capacity of the horizontal safety nets 3 and 4, it can also provide the function of freely extending and retracting the horizontal net.

[0033] The device is easy to use, highly applicable, and low in cost. It further enhances the stability of the manned suspended platform, improves the safety of workers operating at heights, and has a high degree of standardization. This, in turn, improves the dismantling progress of the high-altitude construction platform of the steel structure tower and reduces the risks of high-altitude operations.

[0034] Example 2:

[0035] like Figures 1-14 In the present invention, a crane basket with a stabilizing and balancing device includes an outer frame 1, a plurality of protective net frames 2 are provided on the outer side of the outer frame 1 near the lower end, a counterweight box 5 is provided at the lower end of the outer frame 1, and a counterweight block 501 is provided inside the counterweight box 5.

[0036] The protective mesh frame 2 surrounds the outer frame 1 and is horizontal or nearly horizontal. During placement and operation, debris falls down. The outer frame 1 is usually a rectangular frame structure. Therefore, the protective mesh frame 2 has four panels. The adjacent protective mesh frames 2 are connected by flexible rods 4 at the gaps on the outside of the right angle of the rectangle. Then, a flexible mesh is installed to fill the gaps.

[0037] Because the counterweight 501 is relatively heavy, the overall center of gravity of the suspended platform is lower, making it more stable for the operator to stand.

[0038] The outer frame 1 is equipped with a kickboard 3 near the lower end, and the standing plane is a grid frame or a thin lentil-shaped anti-slip plate laid flat on the frame structure.

[0039] In the preferred embodiment, the counterweight box 5 has an opening at its lower end, and the counterweight block 501 is connected to the lower end of the outer frame 1 via a connecting rope, the length of which is adjustable.

[0040] The overall center of gravity height of the suspended basket can be adjusted by controlling the position of the counterweight 501.

[0041] In the preferred embodiment, the counterweight 501 is provided with a plurality of second suction cups 502 on its outer side.

[0042] In the preferred embodiment, the lower end of the protective mesh frame 2 is hinged to the outer side of the outer frame 1 near the lower end.

[0043] The protective net frame 2 can be flattened to be close to horizontal, or be flipped up against the outer wall of the outer frame 1 for storage.

[0044] In the preferred embodiment, the protective net frame 2 is provided with a plurality of anti-collision sleeves 201.

[0045] In the preferred embodiment, the anti-collision sleeve 201 is provided with a plurality of first suction cups 202 in the circumferential direction.

[0046] The counterweight 501 is a hollow structure, and the inside can be filled with counterweight sand. The outer layer of the anti-collision sleeve 201 and the counterweight 501 is a flexible material. If the gondola swings and collides with the wall or glass curtain wall in windy weather, the anti-collision sleeve 201 plays a role in buffering and shock absorption.

[0047] The counterweight 501 is connected to the lower end of the outer frame 1 through a winding mechanism. When the wind blows, the hoist rope is first wound to reduce the vertical distance of the gondola, and at the same time, the winding mechanism is released, so that the counterweight 501 is lowered. Because the counterweight 501 is heavy and the connecting rope is long, the gondola is separated into two parts with concentrated weight, and the natural frequencies of the two parts when swinging are different, so they interfere with each other. Therefore, the swing amplitude of the outer frame 1 in the middle is well suppressed, and the safety of the operator inside is ensured.

[0048] If the wall is a glass curtain wall, when the counterweight 501 swings to collide with the glass curtain wall, part of the second suction cups 502 on the outside of the counterweight 501 will inevitably contact the glass plane and squeeze out air to be adsorbed on the glass.

[0049] Similarly, when the outer frame 1 swings close to the glass curtain wall, the anti-collision sleeve 201 collides with the glass to form a buffer, preventing the glass from being broken and causing secondary damage to the operator or people downstairs. The first suction cup 202 is also adsorbed on the glass to fix the gondola structure.

[0050] When the swing amplitude is large, the first suction cup 202 and the second suction cup 502 will adsorb the glass surface and then be pulled away, losing kinetic energy and reducing the swing amplitude. After repeated times, finally when the swing amplitude is small enough, the outer frame 1 and the counterweight 501 are adsorbed and anchored on the glass surface.

[0051] In the preferred embodiment, a buffer rod device 6 is also provided. The buffer rod device 6 includes a first hinged seat 601, a guide rod 602, a sliding sleeve 604, and a second hinged seat 606. The first hinged seat 601 is hinged to one end of the guide rod 602. The guide rod 602 is sleeved with the sliding sleeve 604. The sliding sleeve 604 is hinged to the second hinged seat 606. The first hinged seat 601 is connected with the protective net frame 2, and the second hinged seat 606 is connected with the outer frame 1.

[0052] The first hinged seat 601 is connected with the protective net frame 2 away from the hinged shaft, forming a rocker mechanism. Pulling the guide rod 602 can lift and store the protective net frame 2.

[0053] The sliding sleeve 604 is further provided with a clamping cavity 607, and a stop ring 608 is arranged in the clamping cavity 607.

[0058] Since the buffer rod device 6 is a moving mechanism, it is easy to injure the personnel in the outer frame 1, so the inner frame 7 is arranged to separate the personnel from the mechanism, thereby improving the safety, and the hollow part of the side wall of the inner frame 7 is provided with a protective net.

[0059] The inner frame 7 and the outer frame 1 are indirectly connected through a damping block 701, and the impact of the outer frame 1 is weakened when it is transmitted to the inner frame 7. The operator stands in the inner frame 7, and each buffer rod device 6 is arranged between the outer frame 1 and the inner frame 7 to separate the moving mechanism from the personnel. The inner frame 7 is lower than the outer frame 1, so that the pulling sleeve 605 can be easily operated from above.
