电动车库门的安装 Installation and electric garage doors 1、轨道的安装：根据门板的宽度和高度确定两轨道固定性的位置并用水平管测水平，再用M8×41㎜的方头螺钉固定。用卷尺测准水平轨与墙壁及两水平轨之间的间距，用水平尺测准水平轨的水平，然后用M6.4×14㎜的小帽螺丝和六角螺帽将水平轨连接件与水平轨和轨道固定性连接固定。用带眼角钢制成两个三角架，然后将其与水平轨的末端用M6.4×14㎜的小帽螺丝、螺帽连接，并用M8×70㎜的膨胀螺栓固定到天棚或墙壁上。 1, rail installation: according to the width and height of the door plank that determines the location of the two orbital fixity and horizontal tube measurement level, reoccupy M8 x 41 ㎜ lag screw fixation. Use tape to measure quasi level track and wall and the spacing between the two levels of rail, use level of quasi level track level, then use M6.4 x 14 ㎜ cap screws and hex nuts to horizontal rail fittings and horizontal rail and rail fixed solid connection. Made two perforated Angle steel tripod, and then with the level of the end of the rail with M6.4 x 14 ㎜ cap screw, nut, connection, and the expansion of the M8 x 70 ㎜ bolted onto the ceiling or wall. 2、扭簧的安装：将扭簧中心支架、尼龙胶圈、固定法兰、与门体重量相匹配的扭簧、锁紧法兰、绕线轮、轴承支架按顺序（分清左右侧）套在镀锌钢管上，并注意各零部件是否安装正确。用M8×41㎜的方头螺钉将扭簧中心支架固定到洞口上部中间位置的短木板上，并注意避开链盒的安装位置。用M8×40㎜的螺栓将扭簧中心支架、尼龙胶圈、固定法兰和扭簧连接，再将扭簧和锁紧法兰连接。然后将轴承支架的下端用M9.5×19㎜的大帽螺丝和螺帽与水平轨连接件连接固定，轴承支架的上端用M8×41㎜的方头螺钉固定到侧木框上。 2, the installation of the torsional spring: at the center of the torsional spring bracket, nylon aprons, fixed flange, match the body weight of torsional spring, locking flange, reels, bearing bracket (distinguish between left and right side) in sequence on the galvanized steel pipe, and pay attention to all components are installed correctly. With the M8 x 41 ㎜ lag screw the hole at the center of the torsional spring bracket to the upper middle of short board, and pay attention to avoid the chain box installation location. Using M8 x 40 ㎜ bolt at the center of the torsional spring bracket, nylon aprons, fixed flange and the torsional spring connection, then torsional spring and locking flange connection. Then use the lower end of the bearing support M9.5 x 19 ㎜ cap screws and nuts and horizontal rail fittings fixed connection, with the top of the bearing support with M8 x 41 ㎜ lag screw fixation to the side of the wooden frame.
