[0026] Example
[0027] This embodiment provides a test device for disconnecting switch support pillars, including a body 1 and a testing mechanism disposed above the body 1. The testing mechanism includes a tensile actuator 2 and a connecting component 3 connected to the tensile actuator 2. The connecting component 3 includes a first connecting member 4 connected to the tensile actuator 2 and a plurality of second connecting members 5 connected to the first connecting member 4. The first connecting member 4 is connected to the tensile actuator 2, and insulating supports 10 are connected at intervals between the second connecting members 5.
[0028] The specific improvements mentioned above are as follows: Figures 1-3As shown, compared to existing technologies, when inspecting the insulating support 10, the first insulating support 10 is connected to the first connector 4, and then the second connector 5 is connected to the other side of this insulating support 10. Then, a home support is connected to the other side of the second connector 5, and so on, in series with one second connector 5 and one insulating support 10. After series connection, the tension actuator 2 starts working, applying a specified tension at a steady speed (the tension can be set by the user). It checks in turn whether the core rod of each insulating support 10 is pulled out from the end, and whether the end accessories are cracked or deformed. If nothing is found, all products in the series are qualified; if any unqualified products are found, they are selected, and another product is replaced in the series for re-inspection. This is superior to existing technologies, as multiple insulating supports 10 can be inspected at once, improving inspection efficiency and effectively reducing costs.
[0029] Based on the above embodiments: the body 1 includes a base plate 11 and a first positioning frame 12 and a second positioning frame 13 arranged on the base plate 11 and facing each other. The stretching actuator 2 is arranged on the first positioning frame 12 and / or the second positioning frame 13. The stretching actuator 2 is provided with a moving shaft 21 that is linked to the stretching actuator 2. An extension shaft 22 connected to the first connecting member 4 is provided on the side of the moving shaft 21 facing away from the stretching actuator 2. The moving shaft 21 can drive the extension shaft 22 to move.
[0030] The specific improvements mentioned above are as follows: Figure 1 As shown, the machine body 1 includes a base plate 11 and a first positioning frame 12 and a second positioning frame 13 disposed on the base plate 11.

The first connecting member 4 on the first positioning frame 12 is fixed to the extension shaft 22. The connecting member on the second positioning frame 13 is fixed to the second positioning frame 13. When the tension driver 2 drives the moving shaft 21 to stretch outward, the extension shaft 22 will move with the movement of the moving shaft 21. The extension shaft 22 drives the first connecting member 4 to stretch from the middle to the side, thereby performing a tensile test on the insulating support column 10.
[0031] Based on the above embodiments: the first connecting member 4 includes a first intermediate block 41, a first connecting rod 42, a second connecting rod 43, and a third connecting rod 44.

[0032] Based on the above embodiments: the insulating support column 10 is provided with connecting blocks 101 at both ends, the connecting blocks 101 are provided with internal threads, and the second connecting rod 43, the third connecting rod 44, the first series rod 52 and the second series rod 53 are all provided with external threads that connect with the internal threads of the connecting blocks 101.
[0033] Based on the above embodiments: the first connecting rod 42, the second connecting rod 43 and the third connecting rod 44 are fastened to the first intermediate block 41 by the first nut 54, and the first series rod 52 and the second series rod 53 are fastened to the second intermediate block 51 by the second nut 55.
[0034] The specific improvements mentioned above are as follows: Figures 2-5 As shown, the first connecting member 4 includes a first intermediate block 41, a first connecting rod 42, a second connecting rod 43, and a third connecting rod 44. The first connecting rod 42 is located on the side where the first intermediate block 41 connects to the extension shaft 22, while the second connecting rod 43 and the third connecting rod 44 are located on the other side. During installation, the first connecting rod 42 and the extension shaft 22 are pressed together. The first intermediate block 41 has three circular grooves. During installation, the first connecting rod 42 is first inserted into the circular groove of the first intermediate block 41, and then tightened with the first nut 54. Then, the second connecting rod 43 and the third connecting rod 44 are inserted into the remaining circular grooves in sequence, and then the second connecting rod 44 is inserted into the third connecting rod 44. 3. The threaded end of the second connecting rod 43 is inserted into the connecting block 101 of the insulating support 10 to complete the threaded connection. Then, the two first connecting rods 52 on the second connecting piece 5 are installed into the connecting block 101 of the insulating support 10. The other end of the first connecting rod 52 is inserted into the second intermediate block 51 and tightened with the second nut 55.

The other side of the second connecting rod 53 is connected to the adjacent insulating support 10. This process is repeated to connect multiple insulating supports 10 together for simultaneous testing.
[0035] Based on the above embodiments: the extension shaft 22 and the first connecting shaft have a sleeve structure 6 for connecting the two. The sleeve structure 6 includes a sleeve plate 61 disposed at one end of the extension shaft 22 or the first connecting shaft and a sleeve shaft 62 disposed at the other end and sleeved with the sleeve plate 61. The sleeve plate 61 is provided with a through groove 63 for the sleeve shaft 62 to pass through, and the sleeve shaft 62 can rotate within the through groove 63.
[0036] Based on the above embodiments: the socket plate 61 is connected to the extension shaft 22 and a pin for connecting the two is provided between the socket plate 61 and the extension shaft 22.
[0037] The specific improvements mentioned above are as follows: Figure 5 As shown, a sleeve structure 6 is provided between the extension shaft 22 and the first connecting shaft.
