Description

Technical Field

[0001] The utility model relates to the technical field of concrete poles, in particular to a two-point lifting anti-rotation device for a concrete pole production crane. Background Art

[0002] Electric poles are made of concrete and steel bars or steel wires. There are two types of concrete poles: ordinary reinforced concrete poles and prestressed concrete poles. The cross-sections of the poles include square, octagonal, I-shaped, circular or other special-shaped sections. The most commonly used are circular and square sections. The length of the poles is generally 4.5 to 15 meters.

[0003] After searching, a utility model patent with patent announcement number CN212893532U discloses a two-point lifting anti-rotation device for a concrete pole production crane. The utility model adopts a first pulley group and a second pulley group arranged relatively to jointly transmit the lifting force of the cable on the crane. The distribution range of the cable is large, and the transmission component is not easy to rotate at the cable, thereby avoiding the entire concrete pole production crane two-point lifting anti-rotation device from rotating at the cable, thereby avoiding the safety hazards caused by the rotation of the lifting beam or the pole.

[0004] However, the above design still has some shortcomings. In the above design, the concrete pole is lifted only by a hook, and the hook lacks a stable structure, which cannot ensure the smooth transportation and lifting of the concrete pole. When the hook shakes, it is very likely to cause the hook to loosen, causing the concrete pole to fall. In addition, when facing concrete poles of different lengths, it is inconvenient for the staff to adjust the position of the hook, and there are certain limitations. Utility Model Content
