[0028] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0029] A lifting tool for GIS casing lifting operation includes an adjusting frame 1. The adjusting frame 1 is provided with two groups. A pair of lifting rings 101 are fixedly connected on the sides of the adjusting frame 1 that are far away from each other. The lifting hook drives the adjusting frame 1 to be lifted through the lifting ring 101. A reinforcing rib 1011 is fixedly connected at the connection between the lifting ring 101 and the adjusting frame 1. The reinforcing rib 1011 enhances the connection strength between the lifting ring 101 and the adjusting frame 1. A guide slide bar 102 is fixedly connected inside the left adjusting frame 1. A bidirectional threaded rod 103 is rotatably connected inside the right adjusting frame 1. One end of the bidirectional threaded rod 103 is located outside the right adjusting frame 1 and a rotating motor 1031 is installed.

[0030] Among them, see Figure 1 and Figure 3 A positioning frame 2 is provided between the two adjustment frames 1. The corresponding sides of the two positioning frames 2 are rotatably connected with a cross plug joint 201. A through hole 202 is provided at the position corresponding to the positioning frame 2 and the guide slide bar 102. The positioning frame 2 is slidably connected with the guide slide bar 102 through the through hole 202, so as to improve the stability of the spacing adjustment of the positioning frame 2. A threaded adjustment hole 203 is provided at the position corresponding to the positioning frame 2 and the bidirectional threaded rod 103. The rotating motor 1031 drives the bidirectional threaded rod 103 to rotate, so that the positioning frame 2 is threadedly connected with the bidirectional threaded rod 103 through the threaded adjustment hole 203 to adjust the spacing, and drives the cross plug joint 201 to be plugged and connected with the cross plug groove 301, so that the clamping frame 3 is installed between the positioning frames 2.

[0031] For further information, see Figure 1 , Figure 2 and Figure 4 A pair of clamping frames 3 are rotatably connected between the two groups of positioning frames 2. A cross plug groove 301 is provided at the position corresponding to the clamping frame 3 and the cross plug joint 201. The clamping frame 3 is plugged and connected with the cross plug joint 201 through the cross plug groove 301, so that the clamping frame 3 drives the cross plug joint 201 to be rotatably connected with the positioning frame 2 through the cross plug groove 301. The clamping frame 3 is rotated to a vertical state between the positioning frames 2 as a whole, thereby improving the stability of the sleeve body 4 from the horizontal state to the vertical state. A clamping groove 302 is provided on the corresponding side of the two groups of clamping frames 3. A foam protective layer 303 is provided on the inner wall of the clamping groove 302. The clamping groove 302 provides clamping protection for the umbrella skirt part of the sleeve body 4 through the foam protective layer 303. A threaded adjustment hole 2 304 is provided at the center of the bottom side of the clamping frame 3. A through hole 2 305 is provided on both sides of the threaded adjustment hole 2 304 on the bottom side of the clamping frame 3. The sleeve body 4 is clamped between the clamping frames 3.

[0032] For further information, see Figure 2A clamping adjustment mechanism 5 is provided below the clamping frame 3. The clamping adjustment mechanism 5 is composed of an adjusting platform 501, a two-way threaded rod 502, a two-way rotating motor 5021 and a two-way guiding slide bar 503. The top of the adjusting platform 501 and the position corresponding to the two-way threaded adjustment hole 304 are rotatably connected with the two-way threaded rod 502. One end of the two-way threaded rod 502 is located on the outer side of the adjusting platform 501 and a two-way rotating motor 5021 is installed. The two-way rotating motor 5021 drives the two-way threaded rod 502 to rotate, so that the clamping frame 3 is threadedly connected with the two-way threaded rod 502 through the two-way threaded adjustment hole 304. The umbrella skirt part of the sleeve body 4 is clamped and fixed by the clamping groove 302. The top of the adjusting platform 501 and the position corresponding to the two-way through hole 305 are fixedly connected with the two-way guiding slide bar 503. The clamping frame 3 is slidably connected with the two-way guiding slide bar 503 through the two-way through hole 305, thereby improving the stability of the spacing adjustment of the clamping frame 3.

[0033] For further information, see Figure 2 A pair of lifting rings 2 6 are fixedly connected to the left side of the clamping and adjusting mechanism 5, and a pair of lifting rings 3 7 are fixedly connected to the right side of the clamping and adjusting mechanism 5. The hook uses the lifting rings 2 6 and the lifting rings 3 7 to convert the state of the casing body 4 through the clamping and adjusting mechanism 5. The connection between the lifting rings 2 6 and the lifting rings 3 7 and the adjusting platform 501 is fixedly connected with reinforcing ribs 2. The reinforcing ribs 2 enhance the connection strength between the lifting rings 2 6 and the lifting rings 3 7 and the adjusting platform 501.

[0034] The working process of the utility model is as follows: first, the clamping adjustment mechanism 5 is placed together with the clamping frame 3 between the positioning frames 2, and the rotating motor 2 5021 drives the two-way threaded rod 2 502 to rotate, so that the clamping frame 3 is threadedly connected with the two-way threaded rod 2 502 through the threaded adjustment hole 2 304, and the umbrella skirt part of the casing body 4 is clamped and fixed by the clamping groove 302. The clamping groove 302 provides clamping protection for the umbrella skirt part of the casing body 4 through the foam protective layer 303 to avoid collision during the lifting process and damage to the porcelain umbrella skirt. The rotating motor 1031 drives the two-way threaded rod 103 to rotate, so that the positioning frame 2 is threadedly connected with the two-way threaded rod 103 through the threaded adjustment hole 203 to adjust the spacing, and drives the cross plug 20 1 is plugged into the cross plug groove 301, so that the clamping frame 3 is installed between the positioning frames 2, and the hook lifts the lifting ring 101, the lifting ring 26 and the lifting ring 3 7 at the same time. When the state of the casing body 4 needs to be changed, the hook lifts the lifting ring 26 upward, and the hooks at the lifting ring 101 and the lifting ring 3 7 remain stationary, so that the clamping frame 3 drives the cross plug connector 201 to rotate and connect with the positioning frame 2 through the cross plug groove 301, and the clamping frame 3 is rotated to a vertical state between the positioning frames 2 as a whole, so as to improve the stability of the casing body 4 from the horizontal state to the vertical state. The rotating motor 1031 drives the bidirectional threaded rod 103 to rotate, so that the positioning frame 2 releases the fixing of the clamping frame 3, so that the casing body 4 can be taken out for installation.

[0035] The entire operation process is simple and convenient. Compared with the existing lifting tooling, the utility model can provide protection for the casing during the lifting process through design, avoid collisions during the lifting process that may cause damage to the porcelain shed, and improve the stability of the casing when it is converted from a horizontal state to a vertical state.
