Technical Field
[0001] The utility model relates to the technical field of transformer maintenance, in particular to a rotary lifting type low-voltage connection box disassembly and assembly device. Background Art
[0002] The three-phase combined transformer of the underground power station is generally arranged in a closed space. Since it is impossible to use large construction equipment such as cranes, when disassembling and assembling equipment such as low-voltage connection boxes about 5 meters above the ground, the equipment weighing about 9 tons is lifted and moved horizontally by using a 13-meter-high crane on the roof. Not only is the operation risky and inefficient, but also the unnecessary workload is increased by erecting and disassembling a series of maintenance racks, which makes the working environment more narrow, further increasing the construction difficulty and risk of the corresponding space. For this reason, it is necessary to design a hydraulic device that can be fixed on the rails and the equipment casing, and can safely and conveniently lift and move large equipment on the ground, so as to fully meet the needs of disassembling and repairing high-altitude equipment such as low-voltage connection boxes. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide a rotary lifting low-voltage connection box disassembly and assembly device, which can safely and efficiently lift and translate large equipment in a closed space on the ground, and avoid using roof hanging points to lift and translate large equipment, so as to meet the needs of disassembly and assembly and maintenance of suspended equipment such as low-voltage connection boxes, and reduce related operation risks, construction difficulty and engineering workload.

[0005] Preferably, the lifting device includes a main rod, at the end of which is hingedly connected a connecting head, which is detachably connected to the first lifting rod and the second lifting rod; and also includes an auxiliary oil cylinder for driving the main rod to rotate.
[0006] Preferably, the main rod and the auxiliary oil cylinder are both hingedly connected to the base, and the upper end of the auxiliary oil cylinder is hingedly connected to the main rod.
[0007] Preferably, the main rod is a telescopic rod, and the connecting head is hinged to the front end of the telescopic part. The telescopic part adopts an oil cylinder.
[0008] Preferably, a fixing rod is further provided between the first lifting rod and the second lifting rod, and a limiting frame for limiting the position of the low-voltage connection box is detachably connected to the fixing rod.
[0009] Preferably, a stopper piece is provided at the end of the translation rod for preventing the low-voltage connection box from sliding out.
[0010] The utility model provides a rotary lifting low-voltage connection box disassembly and assembly device, which can safely and efficiently lift and translate large equipment such as aerial low-voltage connection boxes in a closed space on the ground, fully meet the needs of disassembly and assembly and seal replacement of suspended equipment such as low-voltage connection boxes, and avoid the related operation risks, construction difficulty and engineering workload of using roof hanging points. The device is easy to operate, safe and reliable, and can fully meet the operation needs of confined spaces. BRIEF DESCRIPTION OF THE DRAWINGS
