Abstract

The invention relates to a mechanical structure, in particular to a mobile counterweight achieving mechanism of a luffing jib tower crane. The mechanism comprises an inhaul cable, a herringbone framefront supporting rod, a steel wire rope pulley set, a guide pulley, a hydraulic cylinder with an energy accumulator, a counterweight, an inclined track, a tower crane platform and a herringbone framerear pulling rod. The bottom end of the herringbone frame rear pulling rod is hinged to the tower crane platform, the top end of the herringbone frame front supporting rod and the top end of the herringbone frame rear pulling rod are hinged together, the bottom end of the herringbone frame front supporting rod is fixedly connected with a cylinder barrel of the hydraulic cylinder with the energy accumulator, a piston rod of the hydraulic cylinder with the energy accumulator and the tower crane platform are hinged together, the tower crane platform is provided with the inclined track, the counterweight is suspended on the inclined track, the steel wire rope pulley set is connected with the herringbone frame front supporting rod and the tower crane platform, and the inhaul cable is hinged tothe joint between the herringbone frame front supporting rod and the herringbone frame rear pulling rod. The torque balance problem of the luffing jib tower crane can be solved, and the overall safetyof the tower crane is improved.

Description

technical field [0001] The invention relates to a mechanical structure, in particular to a moving counterweight realization mechanism of a boom-type tower crane. Background technique [0002] With the rise and rapid development of high-rise buildings, the demand for boom-type tower cranes is increasing, especially in the small space of high-rise buildings, and the balance and safety of the boom-type luffing tower cranes are put forward. Higher requirements, which require that the jib tower crane should ensure a balance between the lifting moment and the stabilizing moment during the operation, so as to ensure the overall stability of the tower crane and reduce the bending moment on the tower body. , to improve the strength of the tower body. The use of mobile counterweights to change the change of the balance moment to meet the needs of changes in the lifting moment is currently the main method used, but the movement of the existing mobile counterweights of the boom-type to...
