Claims

[Scope of Utility Model Registration Claim] In the work of hoisting, transporting, and unloading a load using ropes, the proposed device automatically unloads the load when the load rope becomes loose. As shown in Fig. 1, the structure is that there is a spring chamber 18 in the middle of the curved hook-shaped piece body 1, a protrusion 20 for temporarily fixing the rope in the middle of the hook, and the tip of the hook is the tip of the pusher piece 2. It has a conical shape that can be easily inserted into the lower part 8, and the head has a cutout hole 9 into which the rope can be inserted, and on the left and right sides of the cutout hole 9 there are fitting hooks 3 and 5 for fitting and fixing the pusher piece 2. The lower part of the pusher piece 2 is cut out so that the hook-shaped tip of the piece body 1 can fit therein, and in the middle there is a spring chamber 19 cut out into a rectangular shape so that the tip of the spring attached to the piece body 1 can move from side to side. The upper part has an oval cutout hole 10 with an offset center for the rope to enter.
There are fitting hooks 4 and 6 on the left and right sides that fit into the fitting hook of the piece body 1, and a connecting ring 12 for connecting the piece body 1 and the pushing piece body 2 is attached to the brackets 21 and 22. The spring 14 is fixed in the spring chambers 18 and 19 by pins 23 and 24, and the hook is made of a material with a thickness that can withstand hanging loads. The two hooks shaped as shown in the three-dimensional diagram in Figure 1 work together to hold down the rope by the fitting hook until a load is applied, and when the load is applied, the fitting hook releases. The structure is such that when the rope is loosened, the hook support part is separated by the action of a spring, releasing the steel rope and removing the load.
