Problems solved by technology

Due to the large mass and large inertia of the balance weight, vibration will occur when the balance weight starts to brake, which will increase the tension on the balance weight wire rope, which is not conducive to the stability of the structure. At the same time, the vibration of the balance weight may collide with the quay bridge structure , causing potential safety hazards, so it is necessary to design an energy-saving system for quay cranes with vibration reduction functions

Abstract

The invention discloses a quay crane reduction gearbox counterweight energy-saving system with a vibration reduction function. The system is characterized in that a motor, a hoisting reduction gearbox and a hoisting drum are in transmission connection in sequence; and one end of a hoist rope is wound on the hoisting drum while the other end of the hoist rope is wound on a quay crane lifting appliance. The hoisting drum, a balance reduction gearbox and a balance drum are in transmission connection in sequence, one end of a counterweight steel wire rope is wound on the balance drum while the other end of the counterweight steel wire rope bypasses a movable pulley and then is fixedly connected to a quay crane structure through an oil-gas damper, and the movable pulley is fixedly arranged on a counterweight. The direction of the torque of the counterweight acting on the balance drum is opposite to that of the torque of a quay crane trolley lifting appliance acting on the hoisting drum. According to the system, the torque acting on the balance drum by the balance weight is used for counteracting torque acting on the hoisting drum by the quay crane lifting appliance, 25% of energy consumption of quay crane operation is reduced, vibration of the counterweight can be weakened, tension on the counterweight steel wire rope is reduced, the stability of the energy-saving system is improved, and the protection is provided for the quay crane structure and the counterweight.

Description

technical field [0001] The invention relates to the technical field of port loading and unloading equipment, in particular to an energy-saving balance weight system of a quay crane reduction box with a vibration reduction function. Background technique [0002] International ocean cargo transportation has a large volume and low cost. It is the most important mode of transportation for international logistics. At present, 2 / 3 of the total international trade volume is transported by ocean, and more than 90% of my country's total import and export trade volume is through ocean transportation. Ocean transportation is realized. Ports and wharfs are transportation hubs for water and land transportation, and distribution centers for import and export trade materials, and play an important role in promoting the development of the world economy and the prosperity of international trade. With the rapid development of international trade in recent years, the freight volume of port ter...
