摘　　要：针对输电线路导地线接续管液压弯曲无通用校直工具的现状,为确保输电线路接续管压后弯曲变形满足输变电工程架空导线及地线液压压接工艺规程,研制了一种可调节式输电线路接续管弯曲校直工具,通过调节校直承力钩的安装位置,转动承力丝杆上端配有棘轮扳手,能完成不同长度、不同弯曲部的变形接续管的校直,限位杆防止用力过大或视觉误差造成的接续管反向弯曲。该工具确保了输电线路接续管弯曲变形校直质量,提高了设备的可靠性,在输电线路接续管施工工艺控制方面有很好的推广应用价值。Aiming at the current situation that there is no universal straightening tool for the hydraulic bending of the crimping pipe of the ground wire of the transmission line,in order to ensure that the bending deformation of the continuous pipe of the transmission line meets the hydraulic crimping process regulations of overhead conductor and ground wire of the transmission and transformation project,an adjustable transmission line continuous pipe bending and straightening tool is developed.By adjusting the installation position of the straightening load-bearing hook,the upper end of the rotating load-bearing screw is equipped with a ratchet wrench,which can complete the straightening of the deformed splicing tube of different lengths and different bending parts.The limiting rod shall prevent reverse bending of the connecting tube caused by excessive force or visual error.The tool ensures the bending deformation and straightening quality of the transmission line connecting pipe,improves the reliability of the equipment,and has a good promotion and application value in the construction process control of the transmission line connecting pipe.
