Description

[0001] The invention relates to the technical field of insulator detection, in particular to a vibration testing device for detecting the strength of porcelain post insulators. Background Art

[0002] Porcelain post insulators and knife-operated insulators are numerous in power transmission and transformation systems.

A connecting plate (40) for connecting to a detection member (5) located on the same assembly (4) is provided on the assembly (4), and locking holes (44) are provided at both ends of the connecting plate (40). A straight groove (43) is provided on the connecting plate (40), and the straight groove (43) is slidably connected to the slide rod (260); The detection member (5) includes a tool holder (51), a symmetrically distributed guide rod (52) is provided on one side of the tool holder (51), the guide rod (52) is slidably connected to the slide hole (46), a connecting plate (521) is fixedly provided on one end of the guide rod (52), the connecting plate (521) is tightly connected to the return spring (47), a right-angle baffle (522) is provided on the guide rod (52), and a right-angle baffle (552) and a connecting plate (521) are respectively provided on both sides of the same connecting portion (45) for limiting the movement of the tool holder (51); A connecting seat (523) is fixedly provided on the guide rod (52), and a screw rod (524) is fixedly provided on the connecting seat (523). The screw rod (524) passes through a locking hole (44) on a connecting plate (40) located above the detection member (5) and cooperates with a nut to fix the connecting plate (40) used to connect adjacent detection members (5), thereby fixing all detection members (5) located on the same mounting rod (22), so that all detection members (5) located on the same mounting rod (22) move synchronously to detect the insulator. A mounting groove (55) is provided on one side of the detection member (5), and a plurality of fixing grooves are provided in the mounting groove (55). The fixing grooves are used to set different detection angles along the surface of the tool holder (51); A detection block (56) is installed in the fixing groove, and a detection convex portion (57) is fixedly provided at one end of the detection block (56). The detection convex portion (57) is installed in different fixing grooves on the tool holder (51) to form different detection directions. A fixing hole (58) is provided on the tool holder (51). A bolt passes through the fixing hole (58) and is connected to the detection block (56) to fix the detection block (56). The tool holder (51) and the guide rod (52) are connected via a shaft rod (59).
