[0025] The preferred solution is Figure 2 As shown, the positioning clamp 1 includes a clamp ring 101, one end of which is hinged to a connecting plate 102, and the other end of the clamp ring 101 is connected via a locking device 3; the positioning clamp 1 can be flipped outwards to open through the connecting plate 102, and is tightly clamped to the outside of the GIL pipe body 4 through the locking device 3.

[0026] The preferred solution is Figure 2 As shown, the locking device 3 includes a fixing pin 301, which is movably connected to the end of the clamp ring 101 through a second bolt 302. When the fixing bolt 303 is stuck, the fixing pin 301 can be easily removed as a whole; when the position of the positioning clamp 1 is adjusted to the right position, the nut on the fixing bolt 303 can be tightened to lock and fix the ends of the clamp ring 101 on both sides.

[0027] The preferred solution is Figure 1 and 2 As shown, the positioning arm claw 2 includes a vertical plate 201 and a mounting plate 204, and the mounting plate 204 is movably connected to the positioning clamp 1 by a first bolt 205. The vertical plate 201 is arranged between the mounting plates 204, and the bottom of the vertical plate 201 is hinged to the mounting plate 204 by a hinge 203. The mounting plate 204 is provided with a flip positioning pin 206 to fix the flip angle of the vertical plate 201; the end of the vertical plate 201 is provided with a hook claw 202, and the hook claw 202 is clamped with the port of the GIL pipe body 4.

[0031] The operating principle of the device is as follows:

[0032] Step 1. Check the precision-cut end face of the GIL pipe body 4 butt joint to ensure that the verticality and flatness of the GIL pipe body 4 meet the requirements, and clean the burrs and impurity particles on the end face;

[0033] Step 2, open the positioning clamp 1, install it on the GIL pipe body 4, and appropriately tighten the locking device 3 at the end of the positioning clamp 1 to enable fine adjustment of the position;

[0034] Step 3, straighten the vertical plate 201 on the positioning arm claw 2, so that the hook claw 202 at the end of the positioning arm claw 2 lightly clamps the pipe opening of the GIL pipe body 4, and then tap the positioning arm claw 2 with a rubber hammer to make it close to the end face of the pipe opening without any gap; continue to tighten the fixing bolt 303 with a socket wrench until the positioning clamp 1 does not move and there is no gap between the four hook claws 202 and the pipe opening;

[0035] Note: When hitting the positioning arm claw 2 with a rubber hammer, be sure to hit it in turns, do not use too much force, pay attention to controlling the hitting force, and observe visually while hitting, and make sure that there is no bouncing on the contact surface;

[0036] Step 4. Straighten the vertical plate 201 on the positioning arm claw 2 downward, check that the reference surface of the track positioning clamp 1 meets the parallelism requirement from the pipe mouth, plug the welding machine track 6 into the positioning clamp 1, and then lock the welding machine track 6 to complete the installation of the welding machine track 6.
