Problems solved by technology

As the hoisting load increases, the diameter of the wire rope used for the hoisting mechanism becomes larger, the specifications of the pulley and the reel increase exponentially, the working load increases, and the parameters of the lifting cylinder also increase, which will result in a huge hoisting mechanism, which is not conducive to the mechanism. Optimizing the layout also increases the weight of the hoisting mechanism, resulting in a decrease in the performance of the hoisting mechanism and an increase in cost

Abstract

The invention discloses a compact type telescopic wave compensation device. The compact type telescopic wave compensation device is connected to a rack and comprises a multi-stage sliding rod mechanism, a chain wheel transmission mechanism and a hook head; the upper end of the multi-stage sliding rod mechanism is connected to the rack, and the lower end of the multi-stage sliding rod mechanism is connected with the hook head; and the chain wheel transmission mechanism is arranged in the multi-stage sliding rod mechanism, connected with the multi-stage sliding rod mechanism and used for driving the multi-stage sliding rod mechanism to stretch out and draw back. The compact type telescopic wave compensation device is simple and compact in structure, convenient to install, good in flexibility and low in cost.

Description

technical field [0001] The invention relates to the field of marine engineering ships, and more specifically relates to a compact telescopic wave compensating device. Background technique [0002] As the most commonly used engineering ship in marine engineering, the crane ship is an essential tool for offshore loading and unloading, port construction, and various offshore platform construction and hoisting. In the process of offshore operation, the standby rate of the hoisting mechanism due to the seakeeping performance of the ship and the serious swing of the hook head exceeds 50%, resulting in delays in the construction period and reduction in production efficiency, resulting in huge economic losses. Wave compensation refers to the compensation and correction of operating equipment caused by fluctuations in the sea surface. Wave compensation technology plays an important role in offshore replenishment, ocean drilling, and deep-sea exploration. [0003] At present, there ...
