Auxiliary steel ladder for transformer and use method of auxiliary steel ladder
The invention relates to an auxiliary steel ladder for a transformer and a using method of the auxiliary steel ladder, and belongs to the technical field of transformer manufacturing equipment. According to the technical scheme, a hole (22) and a notch (21) are formed in a connecting pipe (2), the diameter of the hole is matched with that of round steel (3), the round steel (3) is perpendicularly welded to the connecting pipe through the hole, and a connecting rod (1) is welded to the top end of the connecting pipe (2) through the notch (21); a round hole I (11) is formed in the connecting rod, the round hole I is matched with the fastener, and the connecting rod is connected to the lower end of the original steel ladder (5) through the fastener (4). The auxiliary steel ladder has the beneficial effects that the auxiliary steel ladder is connected below the original steel ladder through the fastener, so that the problem that the lowermost end of the conventional steel ladder cannot be lower than the lower surface of the transformer oil tank when an underframe, a trolley or a high foundation are arranged below the oil tank is solved, and the height from the first-stage stepping stick at the lowermost end of the steel ladder to the reference surface can meet the national standard; and the device has the advantages of being easy to manufacture, low in cost, convenient to disassemble and assemble and the like.
本发明涉及一种用于变压器的辅助钢梯及其使用方法，属于变压器制造设备技术领域。技术方案是：联管（2）上开有孔洞（22）和豁口（21），孔洞与圆钢（3）的直径相匹配，圆钢（3）与联管通过孔洞垂直焊接，连杆（1）通过豁口（21）焊接在联管（2）的顶端；连杆上开有圆孔一（11），圆孔一与紧固件相匹配，连杆通过紧固件（4）连接在原有钢梯（5）的下端。本发明的有益效果是：在原有钢梯下通过紧固件连接辅助钢梯，既解决了油箱下方有底架、小车或地基较高时常规钢梯最下端无法低于变压器油箱下表面的问题，又能保证钢梯最下端的第一级踏棍距基准面的高度符合国标，且方便拆卸和安装，具有制作简单、成本低廉、拆装方便等优点。
