[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 3 , the auxiliary tool for the catenary joint clamp in this embodiment includes a first positioning clip 1 and a second positioning clip 2. A connecting piece 3 is arranged between the first positioning clip 1 and the second positioning clip 2. A support rod 4 is fixedly installed at the bottom of the connecting piece 3, and a clamp 5 is arranged at the bottom of the support rod 4.

[0023] After the catenary is broken, maintenance personnel need to use a tapered catenary joint clamp to connect the broken part of the catenary. The catenary joint consists of two threaded wedge sleeves, which are respectively sleeved on the two ends of the catenary head. The threaded wedge sleeve is connected to the catenary end through threads to realize the direct transmission of the mechanical tension of the catenary. This auxiliary tool fixes the two threaded wedge sleeves through the first positioning clip 1 and the second positioning clip 2, adjusts the distance between the two threaded wedge sleeves through the connecting piece 3, and fixes the auxiliary tool on the plane through the clamp 5.

[0024] Embodiment 1: The connecting piece 3 includes a mounting rod 301. The mounting rod 301 is fixedly installed on the right side of the first positioning clip 1. A slot 302 is opened at the right end of the mounting rod 301. A threaded rod 303 is inserted into the slot 302, and a nut 304 is threadedly connected to the outer surface of the threaded rod 303.

[0025] During use, the two threaded wedge sleeves of the catenary joint are respectively clamped into the hexagonal groove of the first positioning clip 1 and the second positioning clip 2, and then the wire sleeve of the catenary joint is sleeved between the two threaded wedge sleeves. The two threaded wedge sleeves are connected to the wire sleeve through threads to realize the direct transmission of the mechanical tension of the catenary.

[0026] After the wire sleeve is sleeved between the two threaded wedge sleeves, loosen the nut 304, then move the positioning clamp two 2 to the left. The positioning clamp two 2 drives the threaded rod 303 to move to the left inside the slot 302 until the two threaded wedge sleeves contact the wire sleeve, and then tighten the nut 304 to lock the position of the threaded rod 303.

[0027] Embodiment two: The fixture 5 includes a top plate 501. The bottom of the support rod 4 is fixedly installed with a top plate 501. The bottom of the top plate 501 is fixedly installed with a side plate 502. The bottom of the side plate 502 is fixedly installed with a bottom plate 503. An adjusting rod 504 is threadedly connected to the bottom plate 503. The top of the adjusting rod 504 is movably installed with a movable plate 505. The bottom of the top plate 501 is fixedly installed with a fixing plate 507.

[0028] Before the fastening operation, first fix the device on the plane through the fixture 5. According to the thickness of the plane, rotate the knob 506. The rotation of the adjusting rod 504 drives the movable plate 505 to slide upward in the chute of the side plate 502 through the slider at the rear until the fixing plate 507 and the movable plate 505 clamp both sides of the plane, completing the fixation of the device, and then the fastening operation can be carried out.

[0029] In order to improve the stability and reliability of the fixture 5 during fixation, anti-slip pads are provided on the opposite sides of the movable plate 505 and the fixing plate 507 to increase the friction force, thereby ensuring the clamping effect.

[0030] In summary, for this auxiliary tool for the catenary joint clamp, by setting the positioning clamp one 1 and the positioning clamp two 2, the two threaded wedge sleeves on the catenary joint can be respectively clamped into the hexagonal side card slots of the positioning clamp one 1 and the positioning clamp two 2. Since the positioning clamp one 1 and the positioning clamp two 2 are connected by the connecting piece 3, it can be ensured that the threaded wedge sleeves on the positioning clamp one 1 and the positioning clamp two 2 are on the same horizontal line, making the fastening more uniform and labor-saving.

[0031] Moreover, under the action of the connecting piece 3, the horizontal position of the positioning clamp two 2 can be adjusted, and the distance from the positioning clamp one 1 can be adjusted, so as to facilitate inserting the wire sleeve of the catenary joint between the two threaded wedge sleeves to achieve the fastening operation.

[0032] Furthermore, by setting the fixture 5, the device can be fixed on the plane, so that manual support is not required, and one person can also smoothly complete the fastening operation of the catenary joint wire.
