长期以来,建筑工地上,木作工程中锯材这一工序完全系用手工操作。石钢建筑工程公司三工区木工刘延斌,自己动手制成了一台适合于现场需要的流动电锯(兄图9)。这台电锯已在现场上使用,情况良好。这台机具构造简单,制作方便。它是用2.8瓩电动机作动力,通过三角皮带带动主轴(13)耱动。主轴一端安锯片,锯片旋转就可以工作。主轴的轴承固定于用∠60×60毫米焊接的角钢支架上,角钢支承架焊在卓轮轴的水平承重架上。上部为工作平台台面,固定于四个支承桂上(∠40×40毫米),支承往下边落脚用活动管制作。
For a long time, on the construction site, the process of lumbering in the woodworking project was entirely manual. Liu Yanbin, a woodworking engineer in the Sangong District of Shigang Construction Engineering Company, made a mobile electric saw suitable for the needs of the site (Brother Figure 9). This saw has been used on site and is in good condition. This machine is simple in construction and easy to make. It is powered by a 2.8-inch motor that drives the spindle (13) through the V-belt. One end of the spindle is mounted on a saw blade and the saw blade rotates to work. The bearing of the main shaft is fixed on an angle bracket welded with ∠60×60 millimeters, and the angle bracket is welded to the horizontal bracket of the shaft. The upper part is the working platform table top, which is fixed on four supports Gui (∠40×40 mm), and the support is made with the movable tube under the foot.
