[0025] Please also refer to Figure 1 and Figure 2The utility model provides an explanation of the gas-insulated ring main unit gas box casing assembly tool. The gas-insulated ring main unit gas box casing assembly tool comprises a crossbar 10, a plurality of positioning members 20, and two sliding push members 30. The crossbar 10 is used to be arranged in the gas box of the gas-insulated ring main unit and extends along the arrangement direction of the casing holes. The crossbar 10 is provided with a first slide groove 11 along its axial direction. Each positioning member 20 is slidably connected to the first slide groove 11 and is aligned with each casing hole. Each positioning member 20 is used to insert and position the casing 40 to be installed. The two sliding push members 30 are slidably connected to the two ends of the crossbar 10, and the pushing ends of the two sliding push members 30 are respectively in contact with the two opposite side inner walls of the gas box of the gas-insulated ring main unit.

[0026] It should be noted that the cross bar 10 is suitable for a four-unit gas box body. The cross bar 10 is located in the four-unit gas box body and is fixed in the gas box body by two sliding push pieces 30 abutting against the inner wall of the gas box; a plurality of sleeve holes are provided on the gas box of the environmentally friendly gas insulated ring network cabinet, and a plurality of sleeves 40 to be installed are respectively inserted into each sleeve hole, and the positions of the sleeves 40 to be installed are positioned by inserting a plurality of positioning pieces 20, and then the position of the cross bar 10 is fixed by the sliding push piece 30, so that the sleeves 40 to be installed can be fixed in the sleeve hole for assembly and installation.

[0027] The beneficial effects of the environmentally friendly gas insulated ring network cabinet gas box casing assembly tool provided by the present invention are: compared with the existing technology, the present invention can adjust the position of each positioning member 20 on the cross bar 10 through multiple positioning members 20 slidingly connected to the cross bar 10, so that each positioning member 20 is inserted into the casing 40 to be installed and positions the casing 40 to be installed; the sliding push members 30 at both ends of the cross bar 10 fix the cross bar 10 to the inner wall of the environmentally friendly gas insulated ring network cabinet gas box, so that each positioning member 20 can effectively position the casing 40 to be installed, and a single operator can complete the fixed installation of multiple casings 40 to be installed, which can save the assembly and installation time of the casing 40 to be installed and save human resources.

[0028] In one possible implementation, see Figure 3 The positioning member 20 includes a first slider 21, a positioning tube 22 and a positioning column 23; the first slider 21 is slidably embedded in the first slide groove 11, and the first slider 21 is provided with an internal threaded hole; one end of the positioning tube 22 passes through the first slide groove 11 and is connected to the internal threaded hole; the positioning column 23 is sleeved on the positioning tube 22 and is used to insert the sleeve 40 to be installed.

[0029] It should be noted that the positioning member 20 consists of a first slider 21, a positioning tube 22, and positioning posts 23.

[0031] It should be noted that a through hole 231 can be opened at the center of one end of the positioning column 23. The diameter of the through hole 231 needs to be smaller than the outer diameter of the positioning tube 22. The positioning tube 22 is inserted into the through hole 231 and can be interference fit with the positioning column 23; since the positioning column 23 is made of rubber, the positioning tube 22 inserted into the positioning column 23 can cause the through hole 231 to expand, increase the friction between the positioning tube 22 and the positioning column 23, avoid relative sliding between the positioning tube 22 and the positioning column 23, and prevent shaking when positioning the sleeve 40 to be installed, which can improve the positioning effect of the sleeve 40 to be installed.

[0032] In one possible implementation, see Figure 3 The first sliding groove 11 is a trapezoidal groove or a T-shaped groove.

[0033] It should be noted that the first slide groove 11 can be a trapezoidal groove or a T-shaped groove, and is preferably a T-shaped groove. The first slider 21 is embedded in the first slide groove 11, and a fastening bolt 221 can be provided at one end of the positioning tube 22. The fastening bolt 221 forms a threaded section.
