公路渡船在使用的过程中往往发现,一艘新渡船用上2-3年船头便逐渐低垂下去,使整个渡船变成两头低中间高。一方面对汽车上下渡船有影响、更重要的是渡船船头日渐下垂而加速渡船捐坏,大大的减少渡船的使用年限,因此,渡船这种变形情况是值得我们重视的。1963年我们对两艘出现船头变形的六车渡船进行了加固,今年又对两艘双车渡船进行加固,从已加固的渡船观测,半年多来,船头下垂情况并无发展,效果良好。现将我们加固的方法介绍如下,供大家研究参考,并请给予批评指正。一、渡船船头加固简单装置的构造 1.渡船船头下垂变形的原因,主要有几方面,第一,船头是悬空的,所以结构本身重量作用会引起船头下垂变形;第二,汽车上下渡船的荷重和冲击;第三,长期搁吊在船头的跳板荷重(有些渡口为了渡运方
During the course of using the highway ferry, it is often found that when a new ferry boat is used for 2-3 years, the bow of the vessel gradually lowers and the entire ferry boat turns into two low middle highs. On the one hand, it has an impact on the ferry from top to bottom. On the one hand, it is more important that the bow of a ferry boat droops and accelerates the donation of the ferry boat. This greatly reduces the useful life of the ferry boat. Therefore, the deformation of a ferry boat deserves our attention. In 1963, we strengthened two six-ferry ferries with bow deformations and reinforced two double-ferries this year. From the reinforced ferry vessels, we have seen no progress in bow sagging for more than six months and have achieved good results . Now we reinforce the method described below, for your reference, and please give criticism. First, the ferry bow reinforced simple device structure 1. Ferry bow sag deformation causes, there are several aspects, first, the bow is vacant, so the structure of its own weight will cause sagging bow deformation; second, the car Ferry up and down the load and impact of the ship; third, long-term hanging load at the bow of the springboard (some ferries in order to ferry side
