The tooling assembly 1 includes a first rod 11 and a second rod 12, which can slide relative to each other to adjust their length. The pipe hook 2 is located at the outer end of the first rod 11 and hooks onto the top tube 41 of the pantograph head, thus fixing the auxiliary tooling for pantograph head maintenance to the top tube 41. The lower frame fixing clamp 3 is located at the outer end of the second rod 12 and clamps onto the lower frame 42 of the pantograph, thus fixing the auxiliary tooling for pantograph head maintenance to the lower frame 42.

[0028] In this embodiment, as Figure 2As shown, a slide rail is fixedly mounted on the second rod 12. The first rod 11 is slidably mounted to the second rod 12 along the length of the slide rail. The first rod 11 slides along the length of the slide rail to adjust the length of the tooling assembly 1. A locking clamp 13 is provided at the inner end of the first rod 11 and the second rod 12 to lock or unlock the tooling assembly 1. The locking clamp 13 is connected to the inner end of the first rod 11 and the second rod 12 by a quick-release screw. In this preferred embodiment, when the locking clamp 13 is unlocked, the first rod 11 and the second rod 12 slide relative to each other to adjust the length of the tooling assembly 1. When the locking clamp 13 is locked, the first rod 11 and the second rod 12 cannot slide to fix the length of the tooling assembly 1.

[0029] Furthermore, the first rod 11 and the second rod 12 are made of 40mm-40mm aluminum alloy profiles with a length of 800mm.

[0030] Furthermore, such as Figure 3 As shown, the pipe hook 2 includes a hook body 21, which has a square opening and a drilled hole at the square opening.

[0031] Furthermore, the pipe hook 2 also includes a locking tongue 22, which has a corresponding drilled hole. The hook body 21 and the locking tongue 22 are connected by a butterfly screw 23, which adjusts the size of the opening between the thumb and forefinger of the pipe hook 2.

[0032] Furthermore, the pipe hook 2 also includes a bottom surface, and the bottom surface of the pipe hook 2 is provided with a drilled hole. The outer end of the first rod 11 is provided with a corresponding drilled hole, and the bottom surface of the pipe hook 2 is connected to the outer end of the first rod 11 by a screw.

[0033] Furthermore, such as Figure 4 As shown, the lower frame fixing clip 3 includes a square clamping opening 31, and the left side, bottom side and right side of the square clamping opening 31 are provided with drill holes.

[0034] Furthermore, the left side of the square clamp 31 is drilled and fixed with screws, and the right side of the square clamp 31 is drilled and adjusted in size with butterfly screws 33.

[0035] Furthermore, the lower frame fixing clip 3 also includes a square interface 32, with drilled holes on the left, bottom and right sides of the square interface 32.

[0036] Furthermore, the bottom surface of the square interface 32 is connected to the bottom surface of the square clamp 31 by screws, and the outer end of the second rod 12 is provided with a corresponding drill hole. The left side and the right side of the square interface 32 are fixedly connected to the outer end of the second rod 12 by screws.

[0037] Furthermore, such as Figure 5As shown, the lower frame fixing clamp 3 clamps the lower frame 42 of the pantograph, fixing the pantograph head maintenance auxiliary tooling to the lower frame 42 of the pantograph. Unlock the locking clamp 13 at the inner end of the tooling, extend the tooling to its maximum length, and then lock the locking clamp 13 at the inner end of the tooling. The pipe hook 2 hooks the top tube 41 of the pantograph head, fixing the pantograph head maintenance auxiliary tooling to the top tube 41 of the pantograph head. Unlock the locking clamp 13 at the inner end of the tooling, adjust the pantograph head position to a suitable maintenance height, and then lock the locking clamp 13 at the inner end of the tooling to inspect the pantograph head horn 43.

[0038] The operation method of an auxiliary tooling for pantograph head maintenance according to an embodiment of this utility model is as follows: First, put the pantograph in the inflated and raised state. Adjust the butterfly screw of the lower frame fixing clamp to a suitable position so that the lower frame fixing clamp clamps the lower frame of the pantograph. Unlock the locking clamp at the inner end of the tooling, extend the tooling to its maximum length, and then lock the locking clamp at the inner end of the tooling. Pull down the pantograph so that the pipe hook fully hooks the top tube of the pantograph head, and then adjust the butterfly screw of the pipe hook to a suitable position so that the pipe hook locks the top tube of the pantograph head. Finally, unlock the locking clamp at the inner end of the tooling, adjust the position of the pantograph head to a suitable maintenance height, and then lock the locking clamp at the inner end of the tooling to begin the maintenance of the pantograph.
