Steel wire ropes are easily oxidized and, combined with long-term wear, are prone to breakage after long-term operation. At the same time, when the traction equipment fails (no traction is required), even if the steel wire rope is not broken, the car will fall under the action of gravity, which is not safe enough and cannot cope with these emergencies.

[0024] In this embodiment, the tensile property and strength are high, breakage is not likely to occur, and safety is high.
[0025] Specifically, a second groove 100 is provided at the bottom end of the first groove 70, and two pairs of slide grooves are provided on the inner wall below the second groove 100. The safety mechanism 80 includes a lifting seat 81 that is slidably connected to the first groove 70 up and down, and the lifting seat 81 is fixedly connected to the bottom surface of the cover plate 50 by bolts. A plurality of first springs 82 are welded to the bottom end of the lifting seat 81, and the bottom ends of the first springs 82 are welded to the inner wall below the second groove 100. The lifting seat 81 is hinged with movable long plates 83 at the front and rear, and a long slider 84 that is slidably connected to the slide groove is hinged on the movable long plate 83, and a squeezing clamp 85 is provided on the side away from each other of each pair of long sliders 84 at the front and rear.
[0026] In this embodiment, when the traction steel belt 40 breaks or the traction equipment 30 fails and cannot tow the car 60, the cover plate 50 loses the pull of the traction steel belt 40, and under the pull of its own weight and the strong elastic force of the first spring 82, the cover plate 50 automatically moves down.
