Description

Technical Field

[0001] The utility model relates to the technical field of crane control, and particularly relates to a remote control system for a crane. Background Art

[0002] At present, the pile-wrapping slewing crane is usually installed on the pile legs of various offshore platforms, and is widely used because of its advantages of small platform space occupation, compact structure, large lifting capacity, and long lifting radius.

[0003] For example, a patent document with the Chinese patent application number 201711236045.9 and the publication date of October 15, 2019 discloses a crane, including a mechanical part and a control part. The control part includes a hydraulic system. The hydraulic control system includes a PLC automatic control system, an emergency manual system, a luffing system for driving a luffing winch, a main hoisting system for driving a main hoisting winch, a secondary main hoisting system for driving a secondary main hoisting winch, a slewing system for driving a slewing mechanism, a main motor, a main pump, and a hydraulic oil tank. The main motor drives the main pump, the main pump is connected to the hydraulic oil tank, and the main oil supply pipeline formed at the output end of the main pump supplies oil to the luffing system, the main hoisting system, the secondary main hoisting system, and the slewing system respectively through a hydraulic control proportional multi-way valve. The PLC automatic control system controls the hydraulic control proportional multi-way valve through an electro-hydraulic proportional pressure reducing valve group; the emergency manual system includes an emergency pump group and a hydraulic handle connected to the hydraulic oil tank, and the emergency pump group controls the luffing system, the main hoisting system, the secondary main hoisting system, and the slewing system through the hydraulic handle.

[0004] However, for some cranes in this document, various operations still need to be carried out manually on the crane. Since the pile-wrapping slewing crane is usually installed on an offshore platform, and due to the weak wireless signal on the offshore platform, remote control cannot be reliably achieved, and once an emergency occurs, the safety of workers at sea is difficult to guarantee.
