轨道式高空作业平台

1、起重机钢轨的顶部是凸状的，底部是具有一定宽度的平板，这就增加了与基础的接触面。轨道的截面多为工字形，具有良好的抗弯强度。方钢可以看作平顶钢轨，由于对车轮磨损大，冶金起重机一般只用于起重量较小、运行速度较慢、工作不频繁的起重机。

The top 1, crane rail is convex, the bottom is flat with a certain width, which increases the contact surface with the base. The section of the rail is I-shaped, with good bending strength. The steel can be seen as the top rail, due to wheel wear, metallurgical cranes generally only used from the weight of the smaller, slower, work is not frequent crane.

2、起重机轨道接头接缝一般为一到两毫米，在寒冷地区或安装时气温低于常年使用气温且相差在二十摄氏度以上时，应考虑温度补偿缝隙，取四到六毫米为宜。轨道的接头可为直头，也可制成四十五度角的斜接头，斜接头可使车轮在接头处平稳过渡。

2, crane rail joints is generally one to two mm, in cold areas or installation temperatures below year-round use temperature and a difference of twenty degrees Celsius, the temperature compensation gap should be considered, taking four to six millimeter advisable. Rail joint can be straight head, also can be made into a bevel joint forty-five degree angle, oblique joints can make the wheels at the joints is a smooth transition.

接头处两轨道横向错位和高低差均不得大于一毫米。焊接轨道接头的顺序是由下而上，先轨底后轨腰、轨头，逐层逐道进行堆焊，最后修补周围。焊接其轨道接头时，设置临时卡具固定钢轨，以便焊接。

Joint of two rail transverse displacement and differential height shall not be more than one millimetre. Welded rail joint order is bottom-up, after the end of the first rail rail, rail, welding layer by road for around, finally repair. Welding the rail joints, rail fixed temporary fixtures, for welding.

3、在进行焊接时，其在施焊轨底的每层焊波时，应使用一根焊条焊完，中间避免接用焊条而断弧，前后两层焊波的施焊方向应相反。每个轨道接头的焊接工作应连续进行。以使轨端头保持在较高温度下焊接。

3, in the welding, the welding of rail base of each weld layer wave, should use a welding rod welding end, intermediate to prevent the electrode and arc break, before and after the two layer welding wave welding direction should be the opposite. Each rail joint welding work shall be carried out continuously. To make the rail end keep welding under high temperature.

4、在焊接后，当消除应力热处理后尚未冷却前，须防雨水等淋湿；烧热的紫铜板可以取下沾水冷却，以便于下次再用。当焊接凸起过大时,用砂轮磨光机进行打磨处理，直到与轨头齐平，最后将表面磨光。

4, after welding, when the stress relief heat treatment after the cooling has not been before, beware of rain and other wet; hot plate can be removed with water cooling, in order to facilitate the next time. When the solder bump is too large, the grinding wheel grinder for grinding process, until flush with the rail head, and finally polished surface.

5、轨道的间距应根据门吊跨度尺寸来辅设。轨道纵坡不允许大于百分之一，超过此值时应对大车驱动功率及整机稳定性进行检测，不符合要求应对轨道坡度进行修正，满足此要求后方可投入使用。

5, track spacing should be based on the gantry crane span dimension to the auxiliary. Rail longitudinal slope does not allow more than one percent, more than this value should drive power carts and machine stability testing, do not meet the requirements to track gradient corrected, meet the requirements before put into use.
