The invention discloses a wire rope internal stress slow release device, and relates to mine equipment. The device consists of two parts, namely a fixed rod 2 and a lock, wherein a counter bore is formed in the center of the fixed rod 2; an open groove 2-1 is formed on the tube wall of the counter bore; a hollow section of the fixed rod 2 is cut into symmetric tube clamps 2-2 by the open groove 2-1; a clamp plate 3 is fixed on the tube clamps 2-2; a wire rope 1 is clamped between the two tube clamps 2-2 and is fixed by using a bolt and nut component 4; the lock comprises a lock body 8, a U-shaped rod 11, a lock sleeve 10 and a lock rod 9; the lock rod 2 is connected with the lock body 8 through a bearing 7; the outer end of the bearing 7 is provided with a pressing cover 6; a long straight edge of the U-shaped rod 11 is connected with the end part of the lock body 8; the lock rod 9 is fixed on the lock body 8; the lock sleeve 10 is inserted on the lock rod 9 and a short straight edge of the U-shaped rod 11; and when the coiled wire rope 1 is loosened, an extended rope end is clamped on the fixed rod 2, the U-shaped rod 11 is arranged on a transport tool, and the U-shaped rod 11 and the lock rod 9 are firmly sleeved by utilizing the lock sleeve 10.
Description
technical field [0001] The invention relates to a mine equipment, in particular to a steel wire rope internal stress slowing device used when a mine hoisting winch replaces a steel wire rope. Background technique [0002] A large number of steel wire ropes are used in the lifting and transportation of coal mines, and the steel wire ropes often generate large internal stress during the coiling and unwinding process. If they are not handled properly, safety accidents are prone to occur. Especially when the winch replaces the steel wire, sometimes it is necessary to connect the new and old steel wire rope heads. This connection must be able to make the two ropes rotate with each other, so as to eliminate the radial internal stress of the steel wire rope, so as to avoid the rotation of the steel wire rope and hurt people. ACCIDENT. At present, in many mines, when the winch is changing the rope to loosen the new steel wire rope, the connecting device used generally does not have...
