Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hoisting equipment, in particular to a anti-swing hoisting device for steel structure bridge construction. BACKGROUND

[0002] The construction of a bridge is usually formed by splicing a plurality of prefabricated steel box girders, and during the construction process, the prefabricated steel box girders need to be hoisted to the construction point by hoisting equipment. During the hoisting operation, the accurate positioning of the steel box girder is directly related to the quality of bridge erection. For an ultra-wide and ultra-high large segment steel box girder, when hoisted by multiple point hoisting ropes, the segment box girder will sway back and forth due to factors such as high wind, etc., resulting in unstable hoisting of the box girder. In combination with factors such as high-altitude crosswind installation, multi-layer interchange bridge collision, high-altitude posture difficult to control, and hoisting machinery stability, the installation operation is inconvenient and the hoisting construction risk is increased.

[0003] An invention with the authorized announcement number "CN111824928B" discloses a complex environment steel box girder hoisting equipment, which comprises: a lower beam body, four hoisting points are arranged on the lower beam body; an upper beam body located above the lower beam body; four connecting columns are arranged on the upper beam body, the lower end of any connecting column passes through the lower beam body and is connected with the steel box girder to be hoisted at the bottom of the distribution beam mechanism; a rotating shaft is located between the upper beam body and the lower beam body, and the middle part of the upper beam body and the lower beam body is rotationally connected; three telescopic rods are located between the upper beam body and the lower beam body, and the two ends of any telescopic rod are connected with the upper beam body and the lower beam body respectively. The transition piece of the upper beam body and the lower beam body is arranged between the steel wire rope connected with the hoisting machine and the steel box girder to be hoisted, which greatly reduces the shaking amplitude of the steel box girder caused by other external forces (such as wind force) in complex environment, greatly reduces the probability of construction accidents caused by the shaking of the steel box girder during hoisting, and improves the completeness of construction.

[0058] The working principle and beneficial effects of the above technical scheme are as follows: when the hoisting rope 4 above the fixed plate 7 shakes under the external force, the hoisting rope 4 drives the counterweight 19 to shake, the counterweight 19 drives the plurality of telescopic rods 2001 to stretch and contract, the elastic element in the telescopic rod 2001 can buffer and damp the shaking of the counterweight 19, thereby reducing the shaking amplitude of the counterweight 19, at the same time, the telescopic rod 2001 transmits the force to the damping ring 2002, the contact rod 2005 in the damping ring 2002 slides in the fixed pipe 2003, and the damping spring 2004 stretches and contracts, thereby further damping the shaking of the counterweight 19, as the height of the fixed plate 7 increases, the pulley 2006 slides along the outer wall of the sleeve pipe 901 step by step, as the diameter of the sleeve pipe 901 gradually increases, the compression degree of the damping spring 2004 gradually increases, on the one hand, the connection strength between the damping ring 2002 and the sleeve pipe 901 is improved, and the shaking of the damping ring 2002 is reduced, on the other hand, the damping force of the damping ring 2002 on the telescopic rod 2001 increases, and the restriction on the counterweight 19 gradually increases, when facing the larger wind force at a high place, the counterweight 19 is more stable, and the shaking degree of the hoisting rope 4 above the fixed plate 7 is reduced, by arranging the damping assembly 20, the vibration force generated by the hoisting rope 4 above the fixed plate 7 can be subjected to one-stage damping through the stretching and contraction of the telescopic rod 2001, and subjected to two-stage damping through the damping spring 2004 with variable compression length, thereby reducing the vibration force transmitted to the steel box girder 13, reducing the influence of the external force on the hoisted steel box girder 13, and greatly reducing the shaking amplitude of the steel box girder 13 in the hoisting process, thereby reducing the hoisting risk.
