设计简介
摘 要
现实当中我们看到的登船梯给我们的感觉是很笨重,不方便,如果用于游船是可行的,但是如果用于航母或军舰的话,那肯定不能符合使用要求了(一旦码头情况不允许那就会带来麻烦),所以必须研制出一种既轻巧方便又安全能适应军用的登船梯系统,这就是我的课题所要做达到的要求。
我所设计的跳板装置不仅设计了一些机械传动,还在原有的基础上采用了液压传动。采用液压传动的突出优点是:易于实现频繁的起动、换向和变速,且对船舶电站的影响较小;惯性小、位置控制精度较高;输出的力和转矩可以很大,但线速度和转速可以很低,体积和重量却很小;调速范围广。因此,液压传动现已广泛应用在各类船舶上。本课题是我国首艘航母上液压登船梯的设计。跳板(登船梯)主要用于军舰与码头之间人员及限重物资通过或迁移。本登船梯系统即可电动也可手动,手动是通过手摇泵来实现的,手摇泵的运用是为了防止断电情况下登船梯不能使用而设计的。

Abstract
Reality we have seen boarding ladder gives us the feeling is very heavy, inconvenient for cruise ships is feasible, but if for aircraft carriers or warships, it certainly does not meet the requirements (once the pier is notit will cause trouble), it is necessary to develop a lightweight and convenient and safe to be able to adapt to a military boarding ladder system, this is my topic have to do to achieve the requirements.
I designed a springboard device not only designed a number of mechanical transmission, hydraulic transmission still in the original basis. With hydraulic drive of the outstanding advantages: easy to implement frequent starting, commutation and variable speed, and less impact on the ship's power plant; inertia, high precision position control; force and torque of the output can be large, but the line speed and the speed can be very low, very small size and weight; wide speed range. Therefore, the hydraulic drive is now widely used in all types of vessels. The issue is China's first aircraft carrier, the hydraulic design of the boarding ladder. Springboard (boarding ladder) is mainly used for warships to the pier and weight limit supplies through or migrate. The boarding ladder system to the electric can also be manually manually by hand pump, the use of the hand pump is designed to prevent the boarding ladder in case of power failure can not be used.
