摘要该论文设计的是10吨桥式起重机。桥式起重机的组成一般由起重小车、桥架运行机构、小车起升机构、主，端梁桥架金属结构构成。起重小车，起升机构，小车运行机构和小车架三部分组成。桥式起重机起升机构主要包括电动机，制动器，减速器，卷筒，滑轮组和吊钩。电动机通过减速机，传动滚筒的转动，使钢丝绳绕着卷筒起升或者放下的方式来起降重物。起重机小车及安装支架升降的机构和小车运行机构和机架的其他部分，一般采用焊接结构进行设计。

起重机运行机构的驱动方式可分为两大类：即用一台电动机带动长传动轴驱动两边的主动车轮的集中传动方式；另一类为分别驱动、即两边的主动车轮各用一台电动机驱动。本论文小车采用的是集中驱动，大车则采用的是分别驱动。

本论文从桥式起重机的起升机构开始设计，起升机构主要设计的内容主要是确定吊具、滑轮组及钢丝绳，卷筒的型号选择，滑轮的选择，电动机的选择，减速器的选择，制动器的选择，联轴器的选择，以及其中的相关计算：然后设计起重机的运行机构。运行机构设计的主要内容为大小车车轮与轨道的计算选择及其各自运行阻力的计算，电动机与减速器的选择，制动器、联轴器、缓冲器的选取及其相关计算与验算。运行机构分为小车的运行机构和大车的运行机构，小车为集中传动方式；大车为分别传动方式。最后设计起重机的主梁和端梁的金属结构，主梁采用双梁桥架结构，主梁和端梁采用的是焊接联接方式。53180

ABSTRACT This article is design for ten ton bridge crane. It can be pided into ordinary bridge crane; simple girder crane and metallurgical special bridge crane 3 kinds. Ordinary bridge crane is general by lifting trolley and bridge operation organization, bridge metal structure group into Lifting car again by lifting mechanism, trolley mechanism and the car frame of three parts. Lifting mechanism includes motor, brakes, reducer, drum and pulleys. Driving speed reducer electromotor through reel rotation of wire rope around the drum down and lifting weights with. Car frame is a tore and installation of hoisting mechanism and the car mechanism, etc. Parts of the frame are usually for welding structure. Crane operation organization drive mode can be pided into two kinds: one kind is concentrated drive, which is a motor driving long shaft drive on both sides of the active wheels, Another kind is respectively driven, namely on both sides of the active wheel each with a motor drives. The ordinary bridge crane in this article uses concentrated drive, the other uses the respectively driven.

     In this paper from the bridge crane hoisting mechanism began to design, hoisting mechanism is primarily designed to determine the content of the main spreader, pulley and rope, drum type selection, pulleys choice, the choice of motor, reducer choice, brakes selection, selection coupling, and wherein the correlation calculation: the operation and design of the crane mechanism. Operating agencies for the design of the main contents of the cart wheel and rail size calculation options and their respective running resistance calculations, the choice of motor and reduction gear, brakes, couplings, select its associated buffer calculation and checking. Run institutions run into car bodies and carts run institutions, the car is centralized transmission mode; carts to each transmission mode. Final design of the crane girders and metal structure of the end beam, dual-beam bridge girder structure, the main beam and end beam welding is used in connection mode.

Keywords: the bridge crane; structure design。
