内容提要
物料搬运机械主要是在企业 ( 包括码头、料场、矿山和商业货仓等 ) 内部进行物料装卸、运输、升降、堆垛和储存的机械设备。一般包括起重机械、输送机、装卸机械、搬运车辆和仓储设备等；习惯上不包括汽车、铁路车辆、飞机和船舶等交通运输工具，以及输送气体和液体的管道。
本次毕业设计桥式装卸料机就是一种在生产领域可以广泛应用的物料搬运机械。经过四个多月的努力，终于在指导老师悉心指导下完成了本次毕业设计。桥式装卸料机是由起重机改进而来的，因此总体上来是参照起重机的原理来进行设计。本次设计我主要针对该机械的主梁和小车驱动系统进行设计。主梁已经是个成熟的技术项目了，根据不同情况进行不同的选择，按已有的设计准则进行设计。然后对主梁进行校核。小车驱动系统在参考了传统的方案后，进行了新旧方案的对比分析。对小车驱动系统进行了革新。依据已有的设计准则对小车驱动系统的各个零部件进行设计，然后对小车驱动系统的各个零部件进行了校核。使它的传动效率和安全性都有了提高，而且制造难度和传统方案差别不大，实现了经济和效益的双丰收。

Summary
The material transporting machinery mainly is in the enterprise (including wharf, materials yard, mine and commercial goods warehouse and so on) the interior carries on material loading and unloading, the transportation, the fluctuation, piles up with the storage mechanical device. Includes the hoisting machinery, the conveyer generally, loads and unloads the machinery, transports the vehicles and stores in a storehouse the equipment and so on; In custom not including transportation tool and so on automobile, railroad car, airplane and ships, as well as transportation gas and liquid pipeline.
This graduation design bridge type installs the unloading device is one kind in the realm of production may the widespread application material transporting machinery. After more than four months endeavors, finally in instructed teacher under the devotedly instruction to complete this graduation project. Feeder loading bridge is to improve from a crane, so the overall table with reference to the principle of a crane to carry out the design This time designs me mainly to aim at this machinery the king post and the car actuates the system to carry on the design. The king post already was the mature technical project, carries on the different choice according to the different situation, according to the design criterion which has has carried on the design. And then to check on the main beam. The car actuated the system after to refer to the traditional plan, has carried on the new old plan contrast analysis. Finally, actuated the system to the car to carry on the innovation. Design criteria based on the existing drive system on the car all the design components, and then drive to the car system to carry out the various parts of the check.Caused its transmission efficiency and the security all had the enhancement, moreover the manufacture difficulty and the traditional plan difference was not big, has realized the economical and the benefit double abundant harvest.
