1、　其实在对于电动的葫芦上可以知道电动葫芦在作业上先启动起升电动机，把重物起升到适当的高度，再启动运行电动机把重物运到指定的位置，运行小车在单工字钢梁的下缘行走。行走时采用一个电动机驱动运行小车两边的车轮。同时在随着社会的发展和进步上可以知道对于机械行业上的发展，无疑是其中的核心技术的掌握。 其中这样对于电动的葫芦的认识亦是需要注意其中的启动的原理。　　生产线托辊即指应用于各类生产流水线上的托辊，在以往，可能一提到托辊大家联想到的就是输送机、输送带等工业机械或环境较为恶劣的场合，其实在这些环境中也可以将托辊理解为是在生产线上，其实无论哪一种托辊，都是通过运行为企业实现连续不断的生产加工模式，只不过生产线托辊的名称更为贴切。

1, in fact, on to the electric hoist electric hoist can know on the job to start the first lifting motor, a heavy lifting to the appropriate height, weight is up and running again motor shipped to the location specified, run the car walking on the edge of simplex word of girder. When walking, use an electric motor to drive the wheels on both sides of the car. At the same time, as society develops and progresses, we can understand the development of the mechanical industry, which is undoubtedly the core technology. The idea of electric gourds is also something to be aware of. Production line roller which is applied to all kinds of roller on the production line, in the past, probably at the mention of roller is everyone associated with the conveyor, conveyor belt and other industrial machinery or environment is relatively bad, in fact, in these environments can also understand roller as is on the production line, in fact, no matter which kind of roller, is by running for the enterprise to realize continuous mode of production and processing, production line only, it is more suitable to be the name of the roller.

　　事实上，中国辊业网提供的生产线托辊与其他托辊还是存在着一定的差异的。生产线托辊与其他托辊最大的不同就是安装的位置，一般托辊都是安装在输送机上，而输送机械则是直接矗立地面上的。但生产线托辊却是安装在流水线上，而流水线的操作工人们，多站在流水线的两旁，所以如果生产线托辊的安装也是较低或者与地面较近的话，是不利于工人操作的，因此生产线托辊的安装一般高度跟桌子差不多。

In fact, there are still some differences between the production line and the other rolls. Production line roller and other rollers of the biggest difference is the location of the installation, general rollers are installed on the conveyor, conveying machinery is standing on the ground directly. But production line roller is installed on the assembly line, and assembly line operators, many on both sides of a standing in line, so if the installation of production line roller is lower or close to the ground, is not conducive to the workers, so the installation of the production line roller generally highly similar to the table.

　　由生产线托辊组成的生产线的结构优势有：流水过程中由多个相关的子过程组成，这些子过程被称为流水线的“级”或“段”，而段的数目又称为流水线的“深度”。并且，每个子过程都是由专用的功能段组成实现，各个功能段的运行时间应保持基本的向同性，通常时间周期为一个时钟，也称之为一拍。同时，生产流水线的运行需要经过一段的通过时长才可保持稳定性，其流水技术适合于大量重复的加工流程。

Production line composed of production line roller structure advantages are: in the process of water is composed of multiple related sub-processes, these sub-processes are called lines of "level" or "period", and the period of "depth" is also known as the number of lines. And the function of each process are made by special period of implementation of each functional segment running time should maintain the basic isotropic, usually time period as a clock, also called a beat. At the same time, the production line needs to be run through a period of time to be stable, and the running water technology is suitable for a large number of repetitive processes.
