Description

Variable cross-section cable tower reinforcing steel bar portion production lifting device Technical Field The utility model belongs to the field of bridge construction, relates to cable-stayed bridge or suspension bridge cable tower steel bar installation construction, and in particular relates to a variable cross-section cable tower steel bar part hoisting device. Background The construction method directly comprises the steps of splicing and installing the reinforcing steel bars at the tower position in a scattered manner, so that the risk of high-altitude construction can be reduced, the reinforcing steel bar binding quality can be improved, and the construction speed can be increased. When the lifting appliance is used for lifting the steel bar segments of the cable tower, a plurality of lifting points are arranged on the lifting appliance according to the tonnage, the size, the steel bar spacing and other parameters of the steel bar segments, and the steel bar segments are connected through the lifting points. The lifting point layout on the common lifting appliance is fixed, and is suitable for lifting the steel bar segments with fixed cross sections, and for diamond type cable towers, A type cable towers and the like, the cross sections of the steel bar segments gradually shrink along with the increase of the height, and the cross sections of the steel bar segments also continuously change, so that the common lifting appliance cannot adapt to the lifting requirements of the steel bar segments with variable cross sections. Disclosure of Invention The utility model aims to solve the problems and provides a variable cross-section rope tower steel bar part production lifting device which is flexible to adapt to the cross-section change of a steel bar section. The technical scheme of the utility model is as follows: A variable cross-section cable tower reinforcement portion production hoisting device is characterized by comprising a main beam, a plurality of hoisting point devices and a hoisting point serial screw rod, wherein the main beam comprises two parallel longitudinal beams, a certain gap is reserved between the two longitudinal beams, a positioning block is welded between the two ends of the two longitudinal beams respectively, the upper ends of the positioning blocks protrude to a certain height above the top surfaces of the two longitudinal beams, a through hole is formed in the upper end of each positioning block along the direction parallel to the longitudinal beams, each hoisting point device comprises a hoisting rod, two opposite sides of the upper end of the hoisting rod are respectively welded with a cross beam, a through hole penetrating through the hoisting rod is formed between the two cross beams, a lifting lug is welded at the lower end of the hoisting rod, the hoisting point devices are movably arranged on the main beam, the hoisting rod of each hoisting point device is inserted in a gap between the two longitudinal beams, the two cross beams are supported on the top surfaces of the two longitudinal beams along the direction perpendicular to the longitudinal beams, the hoisting point screw rod is inserted into the through holes on the two positioning blocks and the through holes on each hoisting point serial device, the two ends of the hoisting point serial screw rod are respectively screwed with a limiting nut on the two positioning blocks, and the two outer side of each hoisting point serial screw rod is respectively connected with a limiting nut on the two lateral beams of each hoisting point screw rod.
