A bottom plate 14 is arranged on the fixing frame 1, and the bottom plate 14 is connected with the rotating shaft 20 through the tension spring 4; once the cable breaks, the cable collecting wheel loses the tensioning function, the cable collecting wheel 2 moves downwards under the action of gravity, so that the rotating shaft 20 drives the free ends of the two rocking bars 3 to move downwards under the contraction function of the tension springs 4, and self-locking is generated between the vertical through holes and the steel wire ropes 9.
In the actual use process, the friction protrusions used for being in contact with the steel wire rope 9 are arranged in the vertical through holes. And the diameter of the vertical through hole is slightly larger than that of the steel wire rope, once the rocker rotates, friction is generated between the inner wall of the vertical through hole and two side surfaces of the steel wire rope, and the steel wire rope can deform in an S shape at the vertical through hole, so that friction force is further increased, and the effect of locking the steel wire rope is achieved.
In general, in order to ensure that the steel wire rope passes through two vertical through holes in parallel, two groups of guide sliding holes 19 are arranged on the fixing frame 1; the two groups of guide sliding holes 19 are respectively arranged on the upper side and the lower side of the self-locking mechanism; each group of guide sliding holes 19 is two, and corresponds to the vertical through holes in the vertical direction respectively.
In the embodiment of the utility model, the cable collecting wheel loses the action of tension and automatically drops after the cable is broken, so that the rocker of the self-locking mechanism is pulled down, the side wall of the vertical through hole on the rocker and the steel wire rope generate static friction, the locking with the steel wire rope is further realized, and the risk of dropping the cable collecting mechanism is avoided.
In the self-locking cable collecting device for travelers in this embodiment, preferably, the bottom plate 14 is provided with an adjusting bolt 40, and the bottom plate 14 is connected with the tension spring 4 through the adjusting bolt 40, so that the tension of the tension spring can be adjusted to meet the actual requirements of different cable collecting devices.
