支柱一般采用型钢焊接而成，上部用螺栓与支架连接，下部用地脚螺栓与地坪固定。按用途支柱可分为对接支柱和中间支柱，两标准段支架之间采用对接支柱支承，其余（包括端部）则采用中间支柱支承。支柱的设计一般按受压柱的稳定性来控制。

The pillar is usually welded by the steel type steel, the upper part is connected with the bolt and the support, and the bottom is fixed with the ground bolt and the floor.to the use pillar, it can be divided into the docking pillar and the middle pillar. The two bracket is supported by the docking pillar, while the rest (including the ends) is supported by the intermediate support. The design of the pillar is generally by the stability of the compression column.

同时双层滚筒输送机采用一台电机进行驱动，和***的两台滚筒线相比，节约了一台电机和电控装置的开支，这样为企业节约了成本，但是要注意在设计时要注意两层滚筒线之间的高度要高于物料的高度。

At the same time, a double layer roller conveyor is driven by a motor. Compared with the two independent lines, it s***es the expenses of an electric motor and electronic device. This s***es the cost for the enterprise, but attention should be paid to the height of the two layers of the roller line when the design is higher than the material.

链板输送机以标准链板为承载面，由马达减速机为动力传动；我们可以通过多列链板并行，使链板输送机做的很宽并形成差速，利用多列链板的速度差使多列输送在无挤压的情况下变为单列输送。

The chain plate conveyer takes the standard chain plate as the bearing surface, and the motor reducer is driven by the motor. We can make the chain conveyor be very wide and form the differential speed through the multi chain chain plate.

随着科学技术的发展，工业自动化成为国民经济的支柱产业，工业自动化正在改变着人们的生产方式。由于中国潜在的巨大市场和丰富的劳动力资源，世界的工业生产正在向中国转移，中国正成为世界的制造大国。我国滚筒输送线等若干产品的产量已经居世界前列。

With the development of science and technology, industrial automation has become the pillar industry of the national economy, and industrial automation is changing people's production mode. Because of China's potential huge market and abundant labor resources, the world's industrial production is transferring to China, and China is becoming a manufacturing in the world. The output of some products such as roller conveyor lines in China has ranked the highest in the world.
