Cross-type counterweight energy-saving quay crane double-trolley steel wire rope winding system

Abstract

The invention discloses a crossing type counterweight energy-saving quay crane double-trolley steel wire rope winding system which comprises an upper trolley energy-saving winding system, a lower trolley energy-saving winding system, an upper trolley lifting winding system, a lower trolley lifting winding system, an upper trolley walking winding system and a lower trolley walking winding system. The torque of the upper trolley energy-saving steel wire rope acting on the upper trolley lifting winding drum is opposite to the torque of the upper trolley lifting steel wire rope acting on the upper trolley lifting winding drum in direction. The torque of the lower trolley energy-saving steel wire rope acting on the lower trolley lifting winding drum is opposite to the torque of the lower trolley lifting steel wire rope acting on the lower trolley lifting winding drum in direction. Mutual interference of the steel wire ropes of the crossing type counterweight energy-saving quay crane is effectively avoided, the crossing type counterweight energy-saving quay crane is prevented from running faults or influencing the running efficiency due to winding of the steel wire ropes, the structural stability and the running safety of the crossing type counterweight energy-saving quay crane are improved, and the container loading and unloading efficiency of ports and wharfs is improved.

Description

technical field [0001] The invention relates to the technical field of container loading and unloading equipment at ports and wharves, in particular to a double trolley steel wire rope winding system for a traversing balance weight energy-saving quay bridge. Background technique [0002] The quay crane is the most important container handling equipment in the port terminal. The working efficiency of the quay crane directly affects the working efficiency and economic benefits of the port terminal to a large extent. Therefore, it is of great significance to study and improve the working efficiency of the quay crane. [0003] Traditional quayside cranes generally only have one trolley to transfer containers, and the work efficiency is low. Due to the need for a safe distance for the arrangement of the quay cranes in the port wharf, the increase in the number of quay cranes is limited, and it has been unable to meet the working needs of the port wharf. Therefore, the work effic...

Problems solved by technology

[0004] In order to reduce the energy consumption of the double-trolley crossing type quay crane, the method of increasing the balance weight is adopted in the prior art, but since the two trolleys of the crossing type quay crane work together, the wire rope winding system related to the balance weight is added again after the crossing type quay crane The wire rope winding system is more complex and more difficult to arrange, so it is necessary to develop a wire rope winding system suitable for double-car crossing energy-saving quayside cranes to overcome the above problems
