[0035] The working principle and use process of the utility model are as follows: when using the hoist suspension tension travel detection device, the hoist wire rope is directly closed on the surface of the positioning wheel 108 and limited by the limiting structure, and when it is installed and used, when the wire rope is suspended and stressed, the threaded rod 107 is held again to drive the connecting block 105 and the tension detection support wheel 106 to move until the tension detection support wheel 106 is squeezed and contacts the surface of the wire rope and moves to the inner surface of the detection body 101 to perform tension detection, and the tension detection result is displayed on the display screen 102, and when the tension is When the surface of the positioning wheel 108 at the wire rope rolls during force detection, the travel of the wire rope is transmitted to the traveling travel detection module 103 through the positioning wheel 108, and the data is transmitted to the detection body 101 through the traveling travel detection module 103 and displayed on the display screen 102 (and this part is described in detail in the wire rope detection system for shore crane equipment disclosed in the authorized patent application No. 202121636759.0, and will not be described in detail here), thereby facilitating the detection of the traveling travel of the hoist wire rope tension through the detection device body 100;

[0036] Then, before the detection and use, the detection device body 100 is engaged with the clamping plate 1083 in the clamping groove 1082 to close the friction plate 1081 on the inner surface of the positioning wheel 108, and the fixing bolt 1086 is rotated to pass through the inner threaded connection hole 1085 until the end of the fixing bolt 1086 is screwed into the inner threaded hole 1084 and fixed, thereby fixing the friction plate 1081 on the surface of the positioning wheel 108. Therefore, when the wire rope is on the outer surface of the positioning wheel 108 for tension detection, the wire rope contacts the surface wear-resistant and anti-skid protection of the friction plate 1081, and it is not easy to slip during detection. The wire rope drives the positioning wheel 108 to rotate stably through the friction plate 1081, and it is not easy to slip, so as to accurately detect the travel of the wire rope, thereby improving the accuracy of the detection device body 100 in the wear-resistant and anti-skid detection of the positioning wheel 108 during the travel of the hoist wire rope tension.

[0037] Finally, when the detection device body 100 is in the tension travel detection, the handheld threaded rod 107 drives the connecting block 105 and the tension detection support wheel 106 to adjust the support connecting plate 1051 and the control slider 1054 to slide inside the control slide groove 1053 when the support connecting plate 1051 moves, so that the support connecting plate 1051 and the side of the positioning block 104 are stably controlled. The locking bolt 1052 is rotated again to be embedded in the internal threaded hole 1055 to fix the support connecting plate 1051 and the bottom end of the positioning block 104, so as to facilitate stable reinforcement installation during extrusion adjustment. It is not easy for the connecting block 105 to be deformed and skewed during the wire rope movement tension detection, and it is stable for extrusion detection, thereby more accurate tension detection is achieved, thereby improving the accuracy of the detection device body 100 in the stable control detection of the connecting block 105 during the hoist wire rope tension travel detection.
