我们过去检测塔机的轨道水平,均采用专用水准仪。该仪器价格较高,携带不便。为此,我们根据连通管的原理,并考虑到检测轨道的实用性,自制了一台简易水平检测仪,见附图。此简易水平检测仪要成对使用。它可以通过螺钉调节刻度板的高低,用以校正仪器放在同一水平位置上两支玻璃管里的水柱面处于同一刻度高度。支座内镶嵌有圆柱形磁铁,是为了使用时保持支座紧贴在钢轨面上,不易摔倒。使用前,应将两个检测仪置于同一水平面上,从玻璃管口处灌入清水,使两个玻璃管内
In the past we used to measure the track level of the tower crane and used a dedicated level. The instrument is expensive and inconvenient to carry. For this reason, based on the principle of connecting pipes, and taking into account the practicality of the detection track, we have created a simple level detector, see attached figure. This simple level detector is used in pairs. It can adjust the height of the scale plate by screws to correct the water column surface of the two glass tubes at the same scale height. The cylindrical magnet is embedded in the support to keep the support close to the rail surface during use and it is not easy to fall. Before use, the two detectors should be placed on the same level, from the glass nozzle into the water, so that the two glass tubes
