Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described:

[0024] As shown in the figure, the present invention proposes a special sucker for transformer maintenance. The sucker includes an electromagnetic locking device 1, a safety rope collar 2 and a controller 3. The safety rope collar 2 is connected to the electromagnetic locking device 1 to control The device 3 is arranged on the electromagnetic locking device 1.

[0025] Such as Figure 5 As shown, the electromagnetic locking device 1 includes a housing 4 and a magnet layer 5 built in the housing 4. The magnet layer 5 is two upper and lower layers capable of relative translation, and a plurality of magnets 6 are arranged in each layer. The south pole and the north pole correspond between the two adjacent magnets, and the magnets are connected by a yoke. The controller 3 is a device for controlling the mutual translation of the upper and lower magnet layers 5 .

Abstract

The invention discloses a special sucking disc for examining and repairing a transformer. The special sucking disc comprises an electromagnetic type locking device, a safety rope sleeve ring and a controller, wherein the safety rope sleeve ring is connected with the electromagnetic type locking device; and the controller is arranged on the electromagnetic type locking device. According to the special sucking disc for examining and repairing the transformer, in work, the sucking disc is adsorbed on the top of the transformer as an anchor point for a safety belt and a tying rope, and can bear impact gravity of 300kg without dropping, so that the purpose of improving personal and equipment safety during maintenance of the transformer is achieved, a major accident caused by transformer maintenance is reduced, and a target of a low annular accident rate is realized.

Description

technical field [0001] The utility model relates to a special suction cup for transformer maintenance. Background technique [0002] Regular maintenance and defect elimination of substation equipment are inseparable from various climbing tools. At present, there are many kinds of equipment in the substation, such as hydraulic lifting platform, arm truck and so on. Due to the lagging of the corresponding safe climbing operation standards, the existing high-elevating operation tools in the market are messy and of uneven quality, which pose a great threat to personal safety and the safe operation of electrical equipment. [0003] Especially in the work of disconnecting the lead wires of the transformer, because the lead wires are very thick and the tension is very large, it needs to be tied and pulled by one person with a large rope, and one person disassembles and installs the screws to complete. During this process, the safety belts of the staff and the large ropes used for...
