Description

Technical Field

[0001] The utility model relates to the field of transformer production, in particular to a device for transporting and hoisting porcelain parts on transformer bushings. Background Art

[0002] The transformer bushing is an insulator used to support the transformer and also protects the internal electrical components of the transformer. The porcelain parts on the bushing are components made of ceramic materials for electrical insulation and mechanical protection. They are an important part of the bushing. The higher the voltage level, the larger the volume and heavier the weight of the porcelain parts on the bushing, which makes the lifting and assembly of the porcelain parts on the bushing more difficult.

[0003] The traditional method for hoisting porcelain parts on transformer bushings is to use a lifting rope to directly tie the shed of the porcelain parts on the bushings and directly hoist them. The porcelain parts on the bushings are usually transported horizontally. When hoisting, it is generally necessary to first turn the porcelain parts on the bushings from a horizontal state to a vertical state, and then hoist them. During the hoisting process, the paint surface of the porcelain parts is easily scratched, and the porcelain parts are also easy to fall over, which greatly increases the risk of the operation. For example, the patent CN204416900U discloses a transformer bushing hoisting tool, which includes a convex-shaped lifting rod and a lifting rope, which completes the horizontal lifting of the bushing and the change of the horizontal position to the vertical position under the cooperation of the main hook and the auxiliary hook. For another example, the patent CN106429817B discloses a UHV bushing hoisting method, which installs a hoop on the UHV bushing for protective lifting of the UHV bushing, and ensures the integrity of the UHV bushing during the lifting process, avoids damage to the shed, and also ensures that the bushing is in a vertical position at the docking installation. However, the above method is relatively complicated to operate and has low production efficiency. Utility Model Content
