[0029] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0030] Please refer to Figure 1-Figure 8 The embodiment of the utility model provides a rope strength testing device, including an operating frame 1, on which slide grooves 20 are symmetrically opened, and a tensile member is slidably arranged in the slide groove 20, and the tensile member includes a support frame 3 slidably connected to the slide groove 20, and an axle rod 4 is arranged inside the support frame 3, and the two ends of the rope are respectively wound around the axle rod 4, and the rope is stretched and tested for strength by sliding the support frame 3 in the slide groove 20.
[0031] A groove is provided at the center of the shaft rod 4 to facilitate the winding of the rope.
[0032] Since cylinders 2 are installed on both sides of the operating frame 1, the piston ends of the two cylinders 2 are connected to the two support frames 3 respectively, and stretching sensors 5 are installed on one side of the two support frames 3. The sliding of the support frames 3 is achieved by the contraction of the cylinders 2, and the stretching force is collected by the stretching sensors 5. The strength of the cable is obtained through the existing calculation method.
[0033] In order to prevent the cable from detaching during the tensile test, a cable fixing mechanism is installed on one side of the upper end of the tensile member, and the cable fixing mechanism includes a mounting plate 6, a bottom fixing sleeve 10 is arranged on the mounting plate 6, slide rails 7 are arranged on both sides of the mounting plate 6, a movable plate 9 is slidably arranged in the slide rail 7, and an end fixing sleeve 11 is arranged on the lower side of the movable plate 9. One end of the wound cable is placed in the bottom fixing sleeve 10, and the movable plate 9 is lowered with the end fixing sleeve 11 to fix the upper side of the cable, thereby enhancing the stability of the cable.
[0034] Among them, a screw rod 8 is rotatably arranged in the slide rail 7, and is connected to the movable plate 9 through the screw rod 8 and the threaded connection, so that the movable plate 9 and the end fixing sleeve 11 are more stably fixed on the cable, and teeth are arranged at both ends of the bottom fixing sleeve 10 and the end fixing sleeve 11, which play an anti-slip role.
[0035] Furthermore, a fixing ring 14 is symmetrically arranged on the shaft rod 4, and a limiting groove 15 is symmetrically opened on one side of the fixing ring 14. Limiting blocks 19 are slidably arranged in the two limiting grooves 15, and a clamping plate 18 is arranged on the lower side of the limiting block 19.

One end of the screw rod 16 is connected to the gear 2 17, and the two ends of the double-headed gear 13 are respectively meshed with the gear 12 and the gear 2 17.
