A jacking device for a low-voltage connecting box of a three-phase combined transformer comprises a main transformer box body, the upper end of the main transformer box body is connected with the low-voltage connecting box, a lifting lug is arranged on the side wall of the main transformer box body, a hook is arranged on the side wall of the low-voltage connecting box, a supporting platform is connected to the lifting lug, and a steel beam is fixedly connected to the supporting platform. A jacking oil cylinder is arranged on the steel beam, the upper end of the jacking oil cylinder is connected with the hook, and the jacking oil cylinder is used for driving the low-pressure connecting box to ascend and descend. According to the three-phase combined transformer low-voltage connection box jacking device and the using method, modular building can be adopted, dismounting and mounting are convenient, application is flexible, the requirement for jacking suspended equipment in various complex environments is met, heavy and long low-voltage connection boxes in the air can be safely and efficiently jacked, and the low-voltage connection boxes can be safely and efficiently jacked. By means of multi-point and peripheral symmetrical jacking, equipment can be prevented from sliding off, the connecting box can be prevented from shaking, and the quality and safety of follow-up sealing replacement are guaranteed. Besides, lifting lugs, hooks and a box body of the equipment are fully utilized, roof lifting points are not adopted, a high-altitude overhauling bent frame does not need to be erected either, therefore, the operation risk and workload are greatly reduced, and the technical problems of lifting of the suspended equipment in the closed space and replacement of sealing pieces are successfully solved.

    一种三相组合变压器低压连接箱顶升装置,包括主变箱体,主变箱体的上端连接有低压连接箱,在主变箱体的侧壁上设有吊耳,在低压连接箱的侧壁上设有挂钩,在吊耳上连接有支撑平台,在支撑平台上固定连接有钢梁,在钢梁上设有顶升油缸,顶升油缸的上端与挂钩连接,用于带动低压连接箱升降。本发明提供一种三相组合变压器低压连接箱顶升装置及用方法,可采用模块化搭建,拆装便捷、运用灵活,适用于各种复杂环境悬空设备顶升的需求,既能够能安全高效顶升空中较重、较长的低压连接箱,也能够顶升相对较轻、较短的低压连接箱,通过多点及四周对称顶升,可以避免设备滑落,也可以防止连接箱晃动,确保后续密封更换的质量、安全。此外,充分利用设备自身吊耳、挂钩、箱体,既不采取屋顶吊点,也不需要搭设高空检修排架,从而大大降低了作业风险及工作量,本发明成功解决了封闭空间悬空设备升降及密封件更换的技术难题。
