Description

Technical Field

[0001] The utility model relates to the technical field of wire ropes, in particular to a wire rope tensioning mechanism. Background Technique

[0002] A wire rope is a rope mainly used for hoisting, traction, tensioning, and load-bearing in industry. Due to its high strength and toughness, and relatively light self-weight, it is widely used in industries such as steel, chemical, transportation, and ports. However, during use, because the workpiece being carried is heavy or the environment is harsh, the wire rope will gradually stretch after being used for a period of time, and the position of the workpiece hanging on the wire rope will drop, affecting the working effect. Therefore, it is necessary to adjust the tightness of the wire rope.

[0003] When the existing wire rope needs to adjust its tightness, the entire wire rope will be loosened and then tightened again. Such a wire rope tensioning process is relatively dangerous and time-consuming and laborious. Therefore, a device that can adjust the tightness of the wire rope at any time is needed.

The steel wire fixing mechanism 4 includes a fixing block 41, a bolt frame 42 and a nut 43. A steel wire tightening mechanism 6 is fixedly installed on the top of the steel wire connecting frame 1 through a fixing bolt 5. The steel wire tightening mechanism 6 includes a winding connecting frame 601, a winding roller 602, a card hole 603, a cartridge 604, a connecting rod 605, a hexagonal block 606, a ratchet tooth 607, a tooth block 608, a spring 609, a slider 610 and a baffle 611.

[0028] As Figure 4 shown, the right side of the fixing block 41 is fixedly connected to the left side of the bolt frame 42. The outer surface of the bolt frame 42 is threadedly connected to the inner surface of the nut 43. The outer surface of the steel wire rope 3 is fixedly connected to the inner surface of the bolt frame 42.

[0029] As Figure 1 and 2As shown, the inner surface of the winding connecting frame 601 is rotatably connected to the outer surface of the connecting rod 605. The outer surface of the connecting rod 605 is fixedly connected to the inner surface of the winding roller 602. The outer surface of the connecting rod 605 is fixedly connected to the outer surface of the ratchet 607. The card hole 603 is formed in the outer surface of the winding roller 602, and the inner surface of the card hole 603 is clamped with the outer surface of the steel wire rope 3.

[0030] The steel wire rope 3 passes through the card hole 603, and then the steel wire rope 3 is wound around the winding roller 602 so that the steel wire rope 3 is wound up on the winding roller 602.

[0031] As Figure 2 and 3 shown, the outer surface of the connecting rod 605 is rotatably connected to the inner surface of the card box 604. The front end of the connecting rod 605 is fixedly connected to the rear end of the hexagonal block 606. The front surface of the card box 604 is fixedly connected to the inner wall of the winding connecting frame 601.

[0032] As Figure 3 shown, the outer surface of the ratchet 607 is movably connected to the outer surface of the tooth block 608. The outer surface of the tooth block 608 is slidably connected to the inner surface of the card box 604. The right side of the tooth block 608 is fixedly connected to one end of the spring 609.

[0033] As Figure 3 shown, the tooth block 608 and the ratchet 607 cooperate with each other so that the ratchet 607 can only rotate in one direction.

Pass one end of the wire rope 3 through the clamping hole 603 of the winding roller 602. Then the user rotates the hexagonal block 606, and the hexagonal block 606 drives the ratchet 607 and the winding roller 602 to rotate through the connecting rod 605. The winding roller 602 winds the wire rope 3 onto the winding roller 602, preventing the wire rope 3 from loosening from the winding roller 602. Then the user loosens the nut 43 and the tightening bolt 2, and then rotates the connecting rod 605. The connecting rod 605 drives the winding roller 602 to tension the wire rope 3. At the same time, the connecting rod 605 drives the ratchet 607 to rotate, and the ratchet 607 drives the tooth block 608 to slide in the clamping box 604. When the ratchet 607 stops rotating, the tooth block 608 blocks the ratchet 607, stopping the rotation of the connecting rod 605. Then the user first rotates the nut 43 on the bolt frame 42, and then screws the two tightening bolts 2 into the wire rope connection frame 1 to fix the wire rope 3 in the wire rope connection frame 1. Then rotate the fixing bolt 5 to remove the winding connection frame 601 from the wire rope connection frame 1.
