The invention provides a connecting device, a wire drawing device and a wire drawing tower. The connecting device is used for connecting an inhaul cable with a wire drawing disc base and comprises a wire drawing bar, a first connector and a second connector, wherein the first end of the wire drawing bar is connected with the first connector, and the first connector is used for being connected with the inhaul cable; the second end of the wire drawing bar is connected with the second connector, and the second connector is used for being connected with the wire drawing disc base. Neither of the two ends of the wire drawing bar of the connecting device need to be bent, so that the diameter and material of the wire drawing bar are not limited and can be selected as needed, and then the strength and stiffness of the wire drawing bar are guaranteed, the bearing capacity of the wire drawing bar is improved, and stress concentration of the wire drawing bar caused by bending of the ends of the wire drawing bar is effectively avoided; when the connecting device is applied to the wire drawing tower, stability and bearing capacity of the wire drawing tower can be ensured.
Description
technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a connecting device, a wire pulling device and a wire pulling tower. Background technique [0002] The guy rod is used to connect the cable and the cable reel foundation, and is mostly used for cable towers, overhead lines, etc. see Figure 1 to Figure 3 , For example, in the guyed tower, the tower body 1' of the guyed tower is fixed underground by the guyed cable 2'. Specifically, the stay cable 2' is connected to the underground cable tray foundation 4' through the stay rod 3', so that part of the stay rod 3' is placed above the ground, and the other part is placed below the ground. In order to ensure a stable connection between the stay bar 3' and the stay cable 2' and the stay base 4', usually, the stay cable 2' and the stay bar 3' are connected through the first connecting hardware 5', and the stay bar 3 ' is connected with the cable tray foundation 4' thr...
