近几年来出现了采用油马达传动 V 型槽轮的动力滑车,特别是绞收围网,大大减轻了起网的劳动强度。浸透海水的网衣很滑,网衣在没有槽沟的鼓轮上无法控制,使 V型槽和网衣之间的滑移很厉害,损坏网衣,并大大降低了起网的效率和速度。目前,人们认识到滑车和网衣间的滑移问题,为此进行了种种试验。如美国专利第2875547号中,提出在 V 型槽轮的沟槽中设置凸缘(如加强筋)以解决这个问题。但这种形式还是没有完全解决好。本发明主要提供起网用动力滑车的 V 型槽轮的结构,以正确掌握网衣,特别是
In recent years there has been the use of oil motor drive V-sheave of the power pulley, especially the twist around the fence, greatly reducing the labor-intensive network. The net soaked in seawater is very slippery, the netting can not be controlled on the drum without the groove, so that the slip between the V-groove and the netting is very serious, the netting is damaged, and the efficiency and speed of netting are greatly reduced . At present, people recognize the slip between the trolley and the clothing, for which a variety of tests. As in U.S. Patent No. 2,875,547, it is proposed to provide flanges (such as stiffeners) in the grooves of the V-shaped sheave to solve this problem. However, this form is still not completely solved. The present invention mainly provides the structure of a V-shaped sheave for the power trolley used for the net, in order to correctly grasp the net clothes, in particular
