Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The embodiment of the invention comprises the following steps:
as shown in figure 1, the invention comprises a U-shaped buckle main beam 1, an adjusting screw 2 and a fixing screw 3 which are matched with the main beam part on the U-shaped buckle main beam 1 to fix the whole structure, and a U-shaped buckle lower plate 4 and an insulating shaft sleeve 5 which are matched with a U-shaped buckle 9 on the U-shaped buckle main beam 1 to fix a stepping motor 10.
The structure of the U-shaped buckle main beam 1 is shown in fig. 2, the main beam 6 is made of square hollow section steel, a first side plate 7 and a second side plate 8 are welded on two sides of the main beam 6, 2 screw holes are formed in the first side plate 7, 1 screw hole is formed in the second side plate 8, and the number of the screw holes is 3 in total, and the screw holes are used for fixing and adjusting the installation position of the main beam. The U-shaped buckle 9 is welded on the side surface of the main beam 6 through a support arm 15 extending out from the side surface of the main beam 6 and used for installing the stepping motor 10, and a reinforcing rib 17 can be arranged on the support arm 15 to enhance the supporting force. The U-shaped buckle 9 comprises a semicircular arc plate 16, a U-shaped buckle upper plate 14 serving as an ear structure is arranged on the side edge of the U-shaped buckle 9, the insulating shaft sleeve 5 is placed in a semicircular arc below the semicircular arc plate 16, and the U-shaped buckle upper plate 14 and the support arm 15 are fixed through bolts after being superposed with bolt holes of U-shaped buckle lower plates 4 on two sides of the insulating shaft sleeve 5 to form the structure of figure 1.
When the current distribution detection device clamp 13 is used, as shown in fig. 3, firstly, the stepping motor 10 is installed on the U-shaped buckle 9 of the U-shaped buckle main beam 1 sleeved with the insulating shaft sleeve 5 and is fixed by bolts.
