[0023] The following will describe in detail the embodiments of the utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the utility model and should not be construed as a limitation of the utility model.

[0024] Please refer to Figure 1 and 5 , a turnover tooling for the moving contact module of GCB, comprising a cross bar 10, a lifting rope 20 and a connecting member 30. A lifting lug 11 is arranged in the middle of the upper side of the cross bar 10. The two ends of the cross bar 10 are respectively connected with a lifting rope 20. Two connecting members 30 are respectively installed at the lower ends of the two lifting ropes 20. The connecting member 30 includes a block 31. Two mounting holes 32 are arranged on the block 31. A plurality of lifting holes for installing eyebolt 34 are also arranged on the block 31. The lower end of the lifting rope 20 is connected with the eyebolt 34.

[0025] The lifting lug 11 on the cross bar 10 is used for connecting with the hook of the lifting equipment. The two ends of the cross bar 10 are respectively connected with a lifting rope 20. The lower end of the lifting rope 20 is connected with a connecting member 30. The connecting member 30 is bolted to the GCB arc extinguishing chamber 40 or the moving contact module 41 of the GCB arc extinguishing chamber through the mounting hole 32. The connecting member 30 is provided with lifting holes for installing eyebolt 34. By connecting the eyebolt 34 with the lifting holes at different positions, it is convenient to turn over the GCB arc extinguishing chamber or the moving contact module of the GCB during maintenance.

[0026] Refer to Figure 5 , one end of the GCB arc extinguishing chamber 40 is the moving contact module 41 of the GCB, and the other end is the static contact module of the GCB. When turning over the GCB arc extinguishing chamber 40 or the moving contact module 41 of the GCB, the connecting member 30 is connected to the moving contact module 41 of the GCB.

[0027] In this embodiment, the lifting rope 20 is made of steel wire rope.

[0028] In this embodiment, refer to Figure 1 , lifting rings 12 are respectively installed at the two ends of the cross bar 10. The upper end of the lifting rope 20 is connected with the lifting ring 12, which is convenient for connecting the lifting rope 20 with the cross bar 10.

[0029] Furthermore, refer to Figure 2 and 3 , a protruding part 321 is arranged on one side of the block 31 where the mounting hole 32 is located. The mounting hole 32 penetrates through the protruding part 321. When installing the connecting member 30, the protruding part 321 is placed in the counterbore of the corresponding threaded hole of the moving contact module of the GCB, and then a bolt is passed through the protruding part 321 and then connected to the corresponding threaded hole of the moving contact module of the GCB, improving the connection stability between the connecting member 30 and the moving contact module 41 of the GCB.

[0030] Refer to Figure 2 and 3, the lifting hole includes a plurality of first connection holes 37 disposed between two mounting holes 32. In this way, the eyebolt 34 can be connected to one of the first connection holes 37 as needed, so as to turn over the GCB moving contact module 41. In this embodiment, the first connection hole 37 is a threaded hole.

[0031] Furthermore, a limiting member 38 is installed at one end of the first connection hole 37, and an extension column 33 is installed at the other end. After the threaded end of the bolt 39 passes through the limiting member 38, it is screwed and fixed to one end of the threaded through hole 331 in the extension column 33, and the other end of the threaded through hole 331 is used to screw and install the eyebolt 34; the limiting member 38 includes an insertion portion 381 and a limiting disk 382. A counterbore is provided on one side of the extension column 33 in contact with the block 31. After the insertion portion 381 passes through the first connection hole 37, it is inserted into the counterbore. Through the above structure, not only the installation position of the eyebolt 34 is extended outward to prevent the lifting rope 20 from interfering with the GCB arc extinguishing chamber 40, but also the installation stability of the eyebolt 34 is improved.

[0032] In this embodiment, second connection holes 35 and third connection holes 36 are respectively provided at both ends of the block 31, and the second connection holes 35 and the third connection holes 36 are respectively threaded holes. Refer to Figure 5 , when the eyebolt 34 is screwed into the second connection hole 35, it is convenient for the GCB arc extinguishing chamber 40 to be in an upright state, and when the eyebolt 34 is screwed into the third connection hole 36, it is convenient for the GCB arc extinguishing chamber 40 to be in a horizontal state.

[0033] The working principle or operation process of the present utility model is as follows:

[0034] Refer to Figure 5 , the connecting member 30 is bolted to the GCB arc extinguishing chamber 40 or the GCB moving contact module 41 of the GCB arc extinguishing chamber through the mounting holes 32.

[0035] Among them, when turning over the GCB arc extinguishing chamber 40, when the eyebolt 34 is screwed into the second connection hole 35, the GCB arc extinguishing chamber 40 is in an upright state, and when the eyebolt 34 is screwed into the third connection hole 36, the GCB arc extinguishing chamber 40 is in a horizontal state; when turning over the GCB moving contact module 41, when the eyebolt 34 is screwed into the second connection hole 35 or the third connection hole 36, the GCB moving contact module 41 is in an upright state, and when the eyebolt 34 is installed in the first connection hole 37, the GCB moving contact module 41 is in an inclined or horizontal state.
