A mechanical grounding device for a rail-mounted crane comprises a connecting frame and two rail contact sliding blocks, the connecting frame is connected with the crane, the two rail contact sliding blocks are in contact with a rail tread, and the two rail contact sliding blocks are connected into a whole through a herringbone support with certain elastic opening and closing capacity. The top end of the herringbone support is connected with a connecting frame, and the connecting frame is connected with the two contact rail sliding blocks through lightning protection conductive copper cables. By means of the elastic opening and closing capacity of the herringbone support and the self angle adjusting capacity of the contact rail sliding block, the height difference of the rail can be compensated, the condition that the rail surface is inclined can be adapted, and the contact rail sliding block makes close contact with the rail tread in the whole stroke. And the symmetrical structural design of the two grounding slide blocks is adopted, and two contact surfaces are formed between the two grounding slide blocks and the rail, so that the overall stability of the structure is improved, the operation is more stable and smooth, the service life is longer, the contact area between the grounding device and the rail surface is also increased, the point discharge phenomenon is avoided, and the guidance quality is better.
一种用于轨道式起重机的机械式接地装置,包括连接架、两个触轨滑块,所述连接架与起重机连接,两个所述触轨滑块均与轨道踏面接触设置,两个所述触轨滑块通过具有一定弹性张合能力的人字撑连接成一体,所述人字撑的顶端与连接架连接,所述连接架与两个触轨滑块之间均通过防雷导电铜索连接。本发明利用人字撑弹性张合的能力,再配合触轨滑块自身调节角度的能力,便能补偿轨道高低差和适应轨面倾斜的情况,使得触轨滑块全行程与轨道踏面紧密接触。并且采用两个触地滑块的对称结构设计,与轨道有两个接触面,增加了结构的整体稳定性,运行更加平稳顺畅,使用寿命更长,也增大了接地装置和轨面的接触面积,避免尖端放电现象,导向性更好。
