[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] like Figs. 1-3 As shown, this utility model embodiment discloses an auxiliary tooling for a load-bearing cable saddle, including a fixing buckle 3, a pry bar 1, a traction rod 2, and a traction rope 4;
[0028] The fixing buckle 3 can be snapped onto the flat bracket of the contact wire; the pry bar 1 is rotatably connected to one side of the fixing buckle 3, and one end of the pry bar 1 can pry the new load-bearing cable.
[0029] One end of the traction rod 2 is rotatably connected to the other side of the fixing buckle 3; one end of the traction rope 4 is fixed to the end of the traction rod 2 near the fixing buckle 3, and the other end can pull the new load-bearing rope to enter the saddle.
[0030] like Fig. 1 and 2 As shown, pry bars and traction rods are symmetrically arranged on both sides of the fixing buckle. The fixing buckle is snapped onto the flat arm. Both the pry bar and the traction rod can rotate relative to the flat arm. In actual application, the new load-bearing cable below the flat arm is pried up by the pry bar and positioned above the flat arm. Then, the new load-bearing cable is pulled into the saddle by the traction rod and traction rope to realize the installation of the new load-bearing cable.
[0031] In this embodiment, both the crowbar 1 and the traction rod 2 are made of scrap steel pipes with a wall thickness of not less than 4mm and a diameter of 3cm. The length of the crowbar 1 is not less than 2 meters and the length of the traction rod 2 is not less than 1m.
[0032] To further optimize the above technical solution, the fixing buckle 3 includes a semi-circular clamp 32 and a connector 31; there are two semi-circular clamps 32, which are fastened to each other on the outer periphery of the flat wrist arm and secured with bolts; there are two connectors 31, one end of which is rotatably connected to the outer wall of the two semi-circular clamps 32, and the other end is fixed with a sleeve and can be fitted with a pry bar 1 and a traction rod 2 respectively; wherein, the pry bar 1 can slide along the corresponding sleeve, and the traction rod 2 can rotate relative to the corresponding sleeve.
[0033] The connector can be a long support from electrified railways. The sleeve of the long support can be fitted around the outer periphery of the pry bar and the traction rod, and the other end is rotatably connected to the side wall of the semi-circular clamp. The connection between the semi-circular clamp and the pry bar and the traction rod is achieved through the connector.
[0034] In some other specific embodiments, it also includes a base plate 33 and fastening bolts 34; one end of each of the two semi-circular clamps 32 is fixed with a lifting lug, and the base plate 33 is arranged corresponding to the lifting lug; the fastening bolts 34 pass through the base plate 33 and the lifting lug in sequence and are fastened by nuts; one end of the connector 31 is rotatably connected to the panel of the base plate 33.
[0035] like Fig. 3 As shown, two semi-circular clamps are provided with lifting lugs at one end and a cantilever arm at the other end, which is fastened with bolts.

One end of the traction rope is fixed, and the other end is connected to the new load-bearing cable. When the traction rod rotates, the traction rope will wrap around the traction rod. As the number of wrapping turns increases, the effective length of the traction rope will shorten, thereby achieving the pulling of the new load-bearing cable. Once the cable is pulled into place, it can be put into the saddle with a gentle push.
[0037] To further optimize the above technical solution and prevent the new load-bearing cable from slipping off the pry bar during the process of prying it up, a support member 6 is fixed to one end of the pry bar 1 that pryes the new load-bearing cable.
