The external end head of described ratchet fuse (9) is square, and is furnished with cubic spanner (17) on it.
Described hook (7) is the hook of band spiral tension spring (15), and the inner of spiral tension spring (15) is connected with the outer end of steel rope (4).
Advantage that the utility model compared with prior art has and effect:
1, the utility model ratchet and steel rope winding position thoroughly isolates, and wire rope grip rope phenomenon can not take place;
2, the utility model steel rope inner termination is fixed in the roller bearing by anchor fitting, and more change steel rope is very convenient;
3, the utility model steel rope external end head connects extension spring, and the phenomenon by tension spring buffering wheel lineoutofservice signal pull when the displacement of rim brake opposite sense suddenly increases prevents wire cable rupture;
4, the utility model free wrench is fixed on the roller bearing, does not need other strap wrenches during operation, and is easy to use, alleviated labor intensity of operating personnel.
5, reasonable, durable in use, safe and reliable, the freedom from repairs of the utility model unit design can be widely used in the anti-slide braking of no locomotive standing vehicle on the rail yard, loading and unloading vehicle and garage maintenance vehicle.
