Description

Tension monitoring device for power transmission line Technical Field The utility model relates to the technical field of tension detection of electric lines, in particular to a tension monitoring device of an electric transmission line. Background In the wire conveying process, the wire is driven to be conveyed forward through a conveying roller, and a certain tension is required to be maintained in the wire conveying process. At present, in the wire conveying device, tension is provided by winding a cable on a tension pulley, and the simplest method is to arrange a balancing weight directly below the tension pulley, and provide tension by the weight of the balancing weight. The patent of publication number CN212374609U discloses an electric wire tension buffer rack, which comprises a support frame, wherein at least two winding wheels are arranged on the support frame, a tension wheel is further arranged on the support frame, the tension wheel is connected with the support frame through a swinging rod, the swinging rod is hinged with the support frame through a transmission shaft, the transmission shaft is connected with a driving mechanism, a tension sensor is further arranged on the support frame, the driving mechanism and the tension sensor are connected with a controller, and the controller controls the driving mechanism to drive the transmission shaft to rotate; This structure is being belonged to, and wire tension buffer frame when using, the tension size of accessible tension sensor real-time supervision electric wire transmission time, and the swing angle control cable's of accessible actuating mechanism control tension wheel tension size simultaneously, but this structure is difficult to spacing the electric wire when using, and the phenomenon that drops appears easily when causing the electric wire distortion causes tension detection not accurate enough. Disclosure of utility model In order to overcome the above-mentioned drawbacks of the prior art, the present utility model provides a tension monitoring device for a power transmission line, which aims to solve the problems set forth in the above-mentioned background art. The utility model provides a tension monitoring device of a power transmission line, which comprises a base, wherein a supporting and monitoring assembly is arranged on the base; The support monitoring assembly comprises a guide cylinder arranged at the top of the base, a support disc is arranged at the top end of the guide cylinder, and a reinforced lifting pad disc for supporting the electric wire is embedded in the middle of the support disc; The middle part of the guide cylinder is connected with a pressurizing rod in a sliding manner, a tension sensor for tension detection is arranged at the bottom of the pressurizing rod, a limiting cavity is formed between the outer side of the supporting disc and the reinforced lifting pad disc, and a plurality of anti-slip pads for slip prevention are fixedly arranged on the outer side of the reinforced lifting pad disc; According to the technical scheme, the cable is positioned through the limiting cavity, the supporting disc can separate the cable, the cable is prevented from falling from the limiting cavity, and meanwhile, the friction force between the cable and the reinforced lifting pad disc is improved through the anti-slip pad on the outer side of the reinforced lifting pad disc; Optionally, in one possible implementation manner, the middle part of the reinforced lifting pad is rotatably connected with a transverse shaft, the transverse shaft is inserted into the top end of the pressurizing rod, the outer side of the pressurizing rod is provided with a slip ring through a bolt, the slip ring is located in the middle part of the guide cylinder and is in sliding connection with the guide cylinder, the bottom of the slip ring is provided with a spring, the spring is sleeved on the outer side of the pressurizing rod, the bottom of the spring extends to the tension sensor, a guide groove is formed in the outer side of the pressurizing rod in a penetrating manner, a guide rod is connected in the guide groove in a sliding manner, and the guide rod is inserted into the top of the guide cylinder; it can be seen that in the above technical scheme, with supporting disk atress drive forcing rod drive sliding ring displacement in the guide cylinder, make the forcing rod displacement simultaneously exert pressure to the spring then, make the pressure transfer to tension sensor on, detect the pressure through tension sensor and realize detecting the tension of cable then, and the supporting disk can effectually avoid the cable to drop, ensure monitoring accuracy, guide and spacing when can displacing the forcing rod through guide way and guide bar, ensure the stability when the forcing rod displacement, ensure tension detection accuracy.
