Description

Technical Field

[0001] The utility model belongs to the field of transformer substation inspection and maintenance, and particularly relates to an auxiliary device for disassembling a rear door of a high-voltage cabinet. Background Art

[0002] Currently, many centrally mounted high-voltage switchgear cabinets in use use a method of fixing the rear cabinet doors by fixing nuts to the cabinet frame and then configuring movable bolts to fix the rear cabinet doors. When conducting preventive tests, the rear cabinet doors need to be opened to conduct relevant work tests on the internal equipment. Due to the heavy weight of the switchgear cabinet doors, the process of opening the rear cabinet doors requires the cooperation of three people, two of whom fix them and the other removes the fixing bolts. However, during the actual disassembly process, although personnel have been arranged to fix the cabinet doors, due to the heavy cabinet doors, a certain degree of displacement will still occur. When the bolts exit or enter the cabinet door bolt openings, they will produce hard friction with the cabinet door, and the edge of the cabinet door will cut the bolt threads. After a period of use, the bolt threads will be damaged. If the damaged bolts are not replaced in time, the damaged bolt threads will also damage the nut threads fixed to the frame during reinstallation, and the cabinet will eventually become unusable, resulting in the loss of maintenance spare parts and an increase in maintenance workload.

DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 As shown, an auxiliary device for disassembling the rear cabinet door of a high-voltage cabinet comprises an operating rod 1 and a support plate 2 arranged at one end of the operating rod 1, a roller mechanism 3 is arranged on the bottom surface of the operating rod 1, a connecting vertical rod 4 is arranged at one end of the operating rod 1, a handle 6 is arranged at the end of the operating rod 1 away from the connecting vertical rod 4, a thread is arranged on the top of the connecting vertical rod 4, and the support plate 2 is "Z"-shaped. The support plate 2 comprises an upper horizontal plate 2-1, a vertical plate 2-2 and a lower horizontal plate 2-3 connected in sequence, a through hole is arranged on the upper horizontal plate 2-1, the top end of the connecting vertical rod 4 is passed through the through hole, two nuts 5 are screwed on the connecting vertical rod 4, and the two nuts 5 are respectively clamped on the top and bottom surfaces of the upper horizontal plate 2-1, the connecting vertical rod 4 is perpendicular to the operating rod 1, the upper horizontal plate 2-1 and the lower horizontal plate 2-3 are parallel to the operating rod 1, and the vertical plate 2-2 is parallel to the connecting vertical rod 4.
