This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0019] like Figure 1-3As shown, the magnetic flux cable tension meter winding device for monitoring cable tension in bridge engineering described in the utility model comprises a cable sleeve 1, which is rotatably connected to a cable 2, and a hand-cranked driving mechanism 3 located at one end of the cable sleeve 1 is provided on the cable 2, and the hand-cranked driving mechanism 3 and the cable sleeve 1 are connected through a gear pair 4 (composed of a driving wheel 41 and a driven wheel 42); the cable 2 is also provided with a cable guide rod 5 parallel to the cable 2, and a fixed guide wheel 6 and a sliding guide wheel 7 are provided on the cable guide rod 5, and the sliding guide wheel 7 is correspondingly arranged above the cable sleeve 1 and moves within its length range.

[0020] Specifically, the cable sleeve 1 is a two-half structure, which can be conveniently snap-fitted and installed on the cable 2. Rotary bearings are provided at both ends of the cable sleeve 1, so that the cable sleeve 1 can smoothly rotate around the cable 2. A driven wheel 42 is installed on one outer end surface of the cable sleeve 1 to facilitate connection with the hand-cranked drive mechanism 3. Since the cable sleeve 1 is a two-half structure, the rotary bearing and the driven wheel 42 installed thereon are also two-half structures (wherein the rotary bearing can adopt a two-half bearing as described in ZL201020643771.X).

[0021] The hand-cranked driving mechanism 3 comprises a frame 31 connected to the cable 2, the bottom plate of the frame 31 is an arc-shaped structure adapted to the cable 2, and is fixed to the cable 2 via a belt buckle 32. A rotating shaft is arranged on the frame 31, a crank 33 is mounted on one end of the rotating shaft, and a driving wheel 41 meshing with a driven wheel 42 is mounted on the other end.

[0022] The length of the cable guide rod 5 is usually greater than that of the cable sleeve 1, and both ends thereof are provided with clamps 51 adapted to the cable 2. Each clamp 51 comprises a fixed arm 511 connected to the cable guide rod 5 and a movable arm 512 hingedly connected to the fixed arm 511, and the handheld ends of the fixed arm 511 and the movable arm 512 are provided with a return spring 513 connecting the two, and the clamping ends of the fixed arm 511 and the movable arm 512 are also provided with a rubber anti-slip pad layer 514.

[0023] A U-shaped fixing frame 52 is provided at one end of the cable guide rod 5, on which a fixed guide wheel 6 is installed; a sliding ring 53 is slidably installed in the middle of the cable guide rod 5, on which a sliding guide wheel 7 is installed. The central axes of the fixed guide wheel 6 and the sliding guide wheel 7 are parallel to each other, and the peripheries of the fixed guide wheel 6 and the sliding guide wheel 7 are both provided with an annular groove adapted to the cable.

[0024] When in use, first install the cable sleeve 1 on the cable 2, and then fix the frame 31 of the hand-cranked drive mechanism 3 on the cable 2 so that it is located at one end of the cable sleeve 1 and the gear pair 4 is meshed; then, fix the cable guide rod 5 on the cable 2 through the clamp 51, pass the cable through the annular grooves of the fixed guide wheel 6 and the sliding guide wheel 7 in turn, and manually fix the end of the cable by wrapping several turns around one end of the cable sleeve 1. Then, hold the sliding ring 53 with one hand and turn the crank 33 with the other hand. According to the rotation speed of the crank 33, gradually push the sliding ring 53 toward the other end of the cable sleeve 1, so that the cable is tightly wound on the cable sleeve 1 in the first layer; then, according to the above method, move the sliding ring 53 in the opposite direction, and tightly wind the second layer on the cable sleeve 1 to complete the cable winding construction.
