Problems solved by technology

[0003] When the crane is lifting objects in the port, it is easily affected by the wind force in the port. Although the current slings can use windproof slings to avoid instability caused by the swaying of the loading plate, it cannot be carried out in time when there are strong winds and waves in the port. Blocking protection will cause strong winds to disperse or damage items due to the impact of waves, resulting in certain economic losses

Abstract

The invention discloses a hoisting device with a horizontal displacement combined jib, which belongs to the technical field of port hoisting. A lifting device with a horizontal displacement combined jib, comprising a walking base, a rotating column connected to the top of the walking base, a turntable connected to the outer wall of the rotating column, and a large tie rod connected to the outer wall of the rotating column, which is far away from the center of the rotating column One end is hingedly connected with the elephant trunk beam, the outer wall of the turntable is connected with the main body of the boom, the end of the boom body away from the turntable is connected with the outer wall of the elephant trunk beam, the outer wall of the elephant trunk bridge is connected with a steel wire rope, the outer wall of the steel wire rope is connected with a sling, and the bottom of the sling is connected There is a loading plate, the bottom of the loading plate is connected with a base shell, the outer wall of the base shell is connected with a wind sensor, the base shell is provided with a driving mechanism, and the driving mechanism is electrically connected with the wind sensor; It can automatically cover the hoisted items to prevent them from being blown away by strong winds or damaged by the impact of waves, which plays a very good protective role.

Description

technical field [0001] The invention relates to the technical field of port hoisting, in particular to a hoisting device with a horizontal displacement combined jib. Background technique [0002] In the normal operation of the port, cranes are an indispensable part. Cranes can transfer items. At present, there are two main types of shoreside container cranes: bridge cranes and portal cranes. Portal cranes are jib cranes. The horizontal movement of the goods is mainly completed by the luffing mechanism. The jib structure of the portal crane mostly adopts a single jib or a rigid four-link combined jib structure, and uses the pulley block compensation method in the hoisting and winding device or uses the rigid four-link The movement track of the end point of the elephant trunk beam in the combined boom realizes the approximate horizontal displacement of the cargo during the luffing process, and the lever live-to-weight balance device is used to compensate the lifting and loweri...
