Reduction gearbox counterweight energy-saving system for quay crane

Abstract

The invention discloses a reduction gearbox counterweight energy-saving system for a quay crane. The reduction gearbox counterweight energy-saving system comprises a hoisting mechanism, a balance reduction gearbox, a balance drum, a counterweight steel wire rope, a movable pulley and a counterweight, and the hoisting mechanism comprises a motor, a hoisting drum and a hoisting reduction gearbox; the motor, the hoisting reduction gearbox and the hoisting drum are connected in sequence; the hoisting drum, the balance reduction gearbox and the balance drum are sequentially connected, one end of the counterweight steel wire rope is wound on the balance drum, the other end of the counterweight steel wire rope bypasses the movable pulley and is fixedly connected with a quay crane structure, the movable pulley is fixedly arranged on the counterweight, and the torque of the counterweight acting on the balance drum is opposite to the torque of a quay crane trolley lifting appliance acting on thehoisting drum. According to the system, electric equipment or operation parameters of the quay crane are not required to be reduced, the operation energy consumption of the quay crane is reduced, thewinding structure of the counterweight steel wire rope is simplified, meanwhile, the length of the hoisting drum is not required to be prolonged, and the service life of the hoisting drum is prevented from being influenced.

Description

technical field [0001] The invention relates to the technical field of port equipment, in particular to an energy-saving system for a balance weight of a reduction box of a quay bridge. Background technique [0002] With the rapid development of the world economy, the scale of shipping logistics is also expanding rapidly, and the global container throughput continues to grow. In order to reduce the transportation cost of containers, container ships continue to be large-scale. At present, 3E-class container ships with a container capacity of 24,000 TEU have been put into use. The requirements for the loading and unloading capacity of ports are getting higher and higher, and port operating costs are also increasing year by year. Among them, the energy consumption of port machinery and equipment is one of the most important parts of port operating costs. [0003] The quay crane is the most important container handling machinery in the port. Its function is to complete the tran...

Problems solved by technology

[0004] The energy-saving technology of the quay crane is mainly to reduce the power consumption equipment and reduce the operating parameters of the quay crane. While reducing energy consumption, it will affect the normal use and loading and unloading efficiency of the quay crane, which cannot meet the loading and unloading requirements of the port.

At present, there is also an energy-saving method using counterweight technology. The traditional counterweight energy-saving technology directly connects the counterweight and the spreader through a steel wire rope to offset part of the weight and play a role in energy saving. However, this method is complicated for wire rope winding and requires It is relatively difficult to arrange a set of wire rope system separately. The other is to wind the counterweight directly on the hoisting drum of the quay bridge through the wire rope. This arrangement simplifies the winding method of the wire rope, but it needs to increase the lifting The length of the drum, increasing the length of the lifting drum will lead to a decrease in the strength of the lifting drum, which will affect the service life of the lifting drum. At the same time, it is difficult to arrange the machine room, and there is no practical engineering application at present
