Quay crane container loading and unloading device having function of deflecting lifting appliance

Abstract

The invention discloses a quay crane container loading and unloading device having a function of deflecting a lifting appliance. The quay crane container loading and unloading device comprises a power drive device (1), a front pulley block (2), a rear pulley block (3), a lifting trolley (4) and the lifting appliance (5), wherein the power drive device (1) is arranged above a quay crane main walking beam (6), the front pulley block (2) is arranged at one end of the quay crane main walking beam (6), the rear pulley block (3) is arranged at the other end of the quay crane main walking beam (6), the lifting trolley (4) is arranged on a walking track of the quay crane main walking beam (6), two steel wire ropes (7) connected with the power drive device (1) are sequentially wound around the front pulley block (2), a pulley block A (13) on the lifting trolley (14), a pulley block B (14) on the lifting appliance (5), and the rear pulley block (3), and finally wound back to the power drive device (1), and a lifting appliance deflecting device (8) is arranged on the quay crane main walking beam (6). The quay crane container loading and unloading device can effectively solve the problem that the container lifting appliance cannot be accurately aligned with a container during unloading of a ship, and the ship unloading efficiency is effectively improved.

Description

technical field [0001] The invention relates to a container loading and unloading device of a quay crane with the deflection function of a spreader, and belongs to the field of engineering machinery. Background technique [0002] With the continuous increase of cargo ships, the throughput of container ports continues to increase, and there are higher requirements for the efficiency of container loading and unloading. In order to improve the efficiency of container loading and unloading, people mostly improve the lifting trolley and invented the double spreader. The lifting trolley can load and unload 2 containers at a time, and the loading and unloading efficiency of containers is twice that of traditional spreaders. [0003] However, in actual operation, it is found that the ship is usually unloaded in order, that is, one end of the ship is unloaded first and then the other end is unloaded, so that the ship will tilt. Since the spreader is horizontal, When grabbing the con...

Problems solved by technology

[0003] However, in actual operation, it is found that the ship is usually unloaded in order, that is, one end of the ship is unloaded first and then the other end is unloaded, so that the ship will tilt. Since the spreader is horizontal, It is difficult to dock with the container when grabbing the container, and manual assistance is required. On the one hand, it will greatly affect the efficiency of unloading the ship, and on the other hand, it will bring danger to the staff.
