At the same time, the present invention also provides a fixing method for a suspension insulator fixing device, which adopts any suspension insulator fixing device as described above, and performs the following steps: (1) Open the opening of the lock, disconnect the The connection between the lock and the insulating rope sleeve; (2) Wrap the insulating rope around the angle steel of the cross arm of the tower; (3) Use the lock to lock the two ends of the insulating rope with the lugs together , and close the lock opening so that the insulating rope cover is fixed on the angle steel; (4) Pass the steel foot of the suspension insulator through the upper end of the long hole on the fixing plate, and slide to the lower end of the long hole so that it is stuck on the lower end of the long hole , to complete the fixation operation.

Compared with the prior art, the present invention has the following beneficial effects: the suspension insulator fixing device can reliably fix the suspension insulator on the cross-arm angle steel, which is convenient for the operator to take the insulator, and effectively eliminates the short-term placement of the suspension insulator. The danger of falling objects from high altitude exists when the cross arm is on, and the fixing method is simple, the operation is convenient, and the work efficiency is improved.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments and related drawings.

As shown in Figures 1 to 3, a suspension insulator fixing device includes a fixing plate 1, and the fixing plate 1 is provided with a long hole 2 with a large top and a small bottom, so that the steel feet 4 of the suspension insulator 3 can be adjusted by the length The upper part of the hole 2 passes through and slides down and is stuck in the lower part of the long hole; the fixed plate 1 is also provided with a through hole 5 located above the long hole 2, and the through hole 5 is pierced with an insulating rope sleeve 6, and the insulating The lifting lugs at the two ends of the rope cover 6 are fastened together by the lock buckle 7 . Among them, the insulation rope cover 6 is made of silk, with a strength of 1T and a length of 300mm. When live work is used, the length of the conductive part can be reduced, and the safety of tool transmission and use can be improved. When using, 6 sets of insulation rope sets Wrapped around the angle steel of the cross arm of the tower.

In this embodiment, the fixing plate 1 has a V-shaped structure, and the long hole 2 is composed of a circular hole at the upper part and a rectangular long hole at the lower part.

In this embodiment, in order to facilitate the access of the suspension insulator, the V-shaped angle of the fixing plate 1 is 120°, the diameter of the round hole is 40mm, and the width of the rectangular long hole is 25mm.

In this embodiment, the lock 7 includes a lock body 701 with an opening and a stop bar 702 for opening and closing. The first opening end at the opening of the lock body 701 is hinged to one end of the stop bar 702. The second opening end at the opening of the lock body 701 is buckled with the other end of the stop rod 702, and the stop rod 702 is sleeved with a sleeve 703, and the sleeve 703 is connected to the stop rod 702 through the internal thread of its inner wall.
