如图 3所示， 左剪刀杆 14和右剪刀杆 9铰接后在图 3所示的鹰形颈贯体 15的上部运 动， 主导杆 7在鹰形颈贯体 15的下部移动， 舌桩具 19连接左剪刀杆 14、 右剪刀杆 9和 主导杆 7， 它在鹰形颈贯体 15的上部和下部之间的空间内移动。 As shown in Fig. 3, the left scissor bar 14 and the right scissor bar 9 are hinged and moved in the upper portion of the eagle-shaped neck body 15 shown in Fig. 3, and the main rod 7 is moved in the lower portion of the eagle-shaped neck body 15, the tongue pile 19 connects the left scissor bar 14, the right scissor bar 9 and the capstan 7, which move in the space between the upper and lower portions of the eagle-shaped neck body 15.
工作原理： working principle:
当使用本发明的平衡式船用拖钩拉住重物 （通常为大的船体） 时， 钩子 10钩住重物， 拖船拖住重物向前移动， 与钩子 10铰接在一起的主导杆 7受到拉力后被拉伸， 主导杆 7 在鹰形颈贯体 15内移动，主导杆 7将钩子 10的拉力通过鹰形颈贯体 15传递给主承梁 16， 由于主承梁 16的一端与船的后端壁 1铰接， 重物对钩子 10的拉力传递给了拖船。 由于钩 子 10的拉力， 主导杆 7拉伸， 与主导杆 7铰接在一起的左剪刀杆 14和右剪刀杆 9在左滚 轮 20和右滚轮 21的挤压下， 左剪刀杆 14和右剪刀杆 9之间的夹角减小， 由此使左副导 杆 13和右副导杆 6之间的夹角也减小，这时左导球 11和右导球 4分别沿着导轨 3向中心 移动， 由于导轨 3的半径大于连接销 17到导轨的垂直距离， 因此左导球 11和右导球 4向 中心移动后， 缩短了连接销 17到左导球 11和右导球 4与导轨 3接触点之间的距离， 左副 弹簧 12和右副弹簧 5被同时压缩， 导轨 3受到左导球 11和右导球 4的压力， 由于导轨 3 安装在拖船上， 因此这时拖船受到了左导球 11和右导球 4给它的两个对称压力和主承梁 16给它的一个拉力， 这时无论拖船拐弯或由于风浪产生颠簸， 左导球 11和右导球 4施加 到拖船上的压力均相等， 这样就保证了拖船的平衡， 使拖船不致产生倾斜或侧翻。
工业实用性 When the weighted marine tow hook of the present invention is used to pull a heavy object (usually a large hull), the hook 10 hooks the weight, the tugboat drags the weight forward, and the main rod 7 hinged with the hook 10 is subjected to After the pulling force is stretched, the main rod 7 moves in the eagle-shaped neck body 15, and the main rod 7 transmits the pulling force of the hook 10 to the main bolster 16 through the eagle-shaped neck body 15, since one end of the main bolster 16 and the ship The rear end wall 1 is hinged, and the pulling force of the heavy object to the hook 10 is transmitted to the tug. Due to the pulling force of the hook 10, the main rod 7 is stretched, and the left scissor rod 14 and the right scissor rod 9 hinged with the main rod 7 are pressed by the left and right rollers 20, 21, the left and right scissor rods The angle between the nine is reduced, whereby the angle between the left and right sub-guides 13 and the right sub-guide 6 is also reduced, at which time the left and right guides 11 and 4 are respectively centered along the guide 3 Moving, since the radius of the guide rail 3 is larger than the vertical distance of the connecting pin 17 to the guide rail, the left guide ball 11 and the right guide ball 4 are moved toward the center, and the connecting pin 17 to the left guide ball 11 and the right guide ball 4 and the guide rail 3 are shortened. The distance between the contact points, the left sub-spring 12 and the right sub-spring 5 are simultaneously compressed, and the guide rail 3 is subjected to the pressure of the left guide ball 11 and the right guide ball 4. Since the guide rail 3 is mounted on the tug, the tugboat is left. The guide ball 11 and the right guide ball 4 give it two symmetrical pressures and a pulling force to the main bolster 16 when the tugboat turns or the bumps due to wind and waves, the left guide ball 11 and the right guide ball 4 are applied to the tugboat. The pressures are equal, which ensures the balance of the tugboat so that the tug does not cause tilting or rollover. Industrial applicability
本发明的平衡式船用拖钩与现有的船用拖钩相比， 由于本发明的平衡式船用拖钩采用 了左副导杆、 右副导杆、 左剪刀杆、 右剪刀杆和主导杆组成的菱形结构， 将钩子对拖船的 拉力转化成左副导杆和右副导杆对导轨的压力， 使得拖船多受到左右平衡的两个力的作 用， 避免了拖船发生倾斜或侧翻， 它能有效改善拖船工的急牵稳性， 从而设计师在卑躬屈 膝船工总体设计时， 就可以更多考虑适航性等性能。 The balanced marine towing hook of the present invention is compared with the existing marine towing hook. The balanced marine towing hook of the present invention comprises a left auxiliary guide, a right secondary guide, a left shear rod, a right scissors rod and a dominant rod. The rhombic structure converts the pulling force of the hook on the tug into the pressure of the left auxiliary guide and the right auxiliary guide on the guide rail, so that the tugboat is subjected to two forces balanced left and right, avoiding the tilting or rolling of the tug, which can Effectively improve the emergency stability of the tugboat, so that the designer can consider the airworthiness and other performances when designing the overall design of the boat.
