Steel-aluminum structure fused four-degree-of-freedom economical active compensation gangway ladder

Abstract

The invention provides a steel-aluminum structure fused four-degree-of-freedom economical active compensation gangway ladder which comprises a movable ladder at the front end and a fixed ladder at the rear end which form a telescopic structure; the fixed ladder is installed on an operation table, the operation table is installed on a rotary table, and the rotary table is installed on a single-degree-of-freedom supporting mechanism. The single-degree-of-freedom supporting mechanism is used for replacing a six-degree-of-freedom compensation platform, and better economical efficiency and adaptability are achieved; the influence of the weight, the strength and the rigidity of the whole machine on the system function under the large-span condition is effectively avoided; double cylinders are used for replacing a traditional steel wire rope winch, and the precision measurement error is effectively improved.

Description

technical field [0001] The invention relates to a four-degree-of-freedom economical active compensation gangway with a steel-aluminum structure fusion. Background technique [0002] With the continuous development of the domestic offshore wind power industry, the requirements for operation and maintenance equipment in terms of functionality, reliability, safety and economical practicability are getting higher and higher. In particular, security and economic applicability are the key considerations for the development of the entire operation and maintenance field. In the field of marine operation and maintenance, there are the following shortcomings in the process of personnel transportation and landing: 1. Using the current relatively advanced six degrees of freedom as a compensation platform, there are situations where the technology is not mature, the application security is poor, and the application risk is relatively high. 2. Based on the consideration of large-scale op...

Problems solved by technology

In the field of marine operation and maintenance, there are the following deficiencies in the process of personnel transportation and landing: 1. Using the current relatively advanced six degrees of freedom as a compensation platform, there are situations where the technology is not mature, the application security is poor, and the application risk is relatively high.

If the six-degree-of-freedom compensation platform is still used for compensation, not only the cost is high, but also the control is complicated, and the later maintenance is relatively difficult

3. It is difficult to meet the precision requirements in the active compensation process by using the traditional wire rope winch to control the telescopic ladder. This is because the wire rope itself has elastic deformation, and the error is large in signal transmission, signal acquisition and output, and it is difficult to meet the closed-loop requirements of the system.

If a single component is still used, it is difficult to implement system redundancy and there is a large safety error
