A hoist for shore bridges

Abstract

The invention discloses a hoister for a quay crane. The hoister comprises a control device, a back-pull bowing device arranged at one side of a stand column and a hoisting device, wherein the hoisting device comprises a hoisting mechanism arranged at the top of the stand column and a sling arranged at the bottom of a cross beam; the hoisting mechanism is connected with the sling; the back-pull bowing device comprises an upper supporting body, a lower supporting body, a steel strand and a driving oil cylinder arranged on the upper supporting body; the upper supporting body and the lower supporting body are both hinged to the stand column; one end of the steel strand is fixedly connected with the lower supporting body, while the other end of the steel strand penetrates through the lower supporting body and the upper supporting body and then is arranged on the driving oil cylinder; the control device is connected with the hoisting device and the driving oil cylinder. The hoister for the quay crane, disclosed by the invention, is simpler in structure and more convenient, and lowers the production cost of the whole elevator.

Description

technical field [0001] The invention belongs to the technical field of container cranes, and in particular relates to a hoist used in the assembly process of container quay bridges. Background technique [0002] Quay cranes, also known as quayside container cranes and bridge cranes, are equipment used to load and unload containers on ships on the shore, and play a very important role in the field of ship technology. [0003] The total weight of the quay crane is about 1600t, including two parts: the upper steel structure frame and the lower door frame. The door frame mainly consists of 4 columns and connecting beams arranged between the columns. The steel structure frame is spliced ​​with many large steel beams The bottom of the steel structure frame is a large beam that bears the overall weight. The total weight of the upper steel structure frame is about 900 tons. When assembling the quay bridge, the upper steel structure frame is usually assembled on the ground. Then lif...
