A swivel arm swivel device for a built-in brush belt type oil spill recovery ship

Abstract

The invention belongs to the related field of spilt oil recovery vessel accessory equipment and discloses a rotary arm rotary device used for a brushing belt built-in type spilt oil recovery vessel. The rotary arm rotary device comprises a rotary base, a rotary central shaft, a rotary arm, a deep groove ball bearing, a thrust conical bearing and double rotary oil cylinders. The front end of the rotary base is provided with an upper cover plate and a lower cover plate which are provided with an upper locking cap and a lower locking cap. The rotary central shaft is mounted between the upper locking cap and the lower locking cap. An upper shaft sleeve of the rotary central shaft is fixed to the rotary arm, and a lower shaft sleeve of the rotary central shaft is fixedly connected with a bearing seat and then fixed to a lower plate of the rotary arm. The deep groove ball bearing and the thrust conical bearing are arranged in the mode that inner rings and shaft washers of the deep groove ball bearing and the thrust conical bearing and the bearing seat are mounted in an interference fit mode. The two oil cylinders are in parallel connection to achieve driving on the rotary arm. Through the rotary arm rotary device, axis perpendicularity can be further ensured while friction in the rotating process is effectively reduced, mechanical property requirements are fully met, and meanwhile, the rotary arm rotary device has the advantages of being stable in operation, high in bearing capacity, easy to control and the like.

Description

technical field [0001] The invention belongs to the related field of auxiliary equipment of an oil spill recovery ship, and more particularly relates to a rotating arm rotation device for a built-in brush belt type oil spill recovery ship. Background technique [0002] With the rapid development of maritime oil transportation, oil spill accidents from ships have also increased significantly. The frequent occurrence of marine oil spill accidents not only pollutes the marine ecological environment, but also brings serious harm to the world's ecological environment, affecting the sustainable development of the entire human race. Therefore, the timely recovery of sea oil spills is related to the development of the marine environment and even the entire human race. [0003] At present, the main function of the rotating arm rotating device of the large built-in brush belt type oil recovery ship is to complete the deployment of the oil containment boom on the sea surface. During t...

Problems solved by technology

However, further studies have shown that (1) most of the rotating devices currently used are gear transmissions or swing cylinders, which not only require a large installation space, but also make it difficult to lubricate the friction surfaces; During work, the rotating running-in surface is easily corroded by seawater and sea breeze, and the control operation is relatively difficult, and the bearing capacity is limited
