Description

Technical Field

[0001] This utility model relates to the field of pulleys, and in particular to a pulley that can be quickly disassembled. Background Technology

[0002] Pulley assemblies are typically used in conjunction with rigging, lifting equipment, winches, etc., in lifting operations to transport and hoist various structural equipment and components, and are an indispensable lifting tool.

[0003] Currently, when using pulley assemblies, the rope is usually passed through the pulley and positioned on the pulley's sheave. However, if one end of the rope is pre-attached to a weight, and the pulley and rope are transported separately, such as in a marine winch where the pulley is fixed to the ship, the rope, due to its length, needs to be spliced ​​and the winch frame replaced. In the initial winch frame, because the rope and probe are fixed on the winch frame, it is difficult to pass the probe and rope through the pulley. Moreover, because splicing is required midway, the knot is difficult to pass through the pulley, making the pulley difficult to use. Utility Model Content

The spring 612 is compressed, and the left side of the limiting cylinder 611 leaves the second opening of the second baffle 2. The limiting cylinder 611 is rotated counterclockwise upward. At this time, the right side of the second rotating shaft 416 passes through the square through hole, releasing the limiting cylinder 611. The spring 612 rebounds, and the limiting cylinder 611 returns to its original position. Continue rotating upwards, that is, rotate the second pulley 415 to the left side of the first baffle 1; Step 4: Repeat Step 3 until the second pulleys 415 of both second pulley assemblies 4 are located on the left side of the first baffle 1; Step 5: Pass the cable between the bottom of the two second fixing plates 511 and the top of the second baffle 2, and place it on the top of several first pulleys 311; Step Six: Rotate each limiting cylinder 611 clockwise. When the limiting cylinder 611 reaches the square through hole, the operator holds the first baffle 1 and the second baffle 2 and pulls the limiting cylinder 611 to the right. The spring 612 is compressed. Continue to rotate the limiting cylinder 611 clockwise. Each second rotating shaft 416 enters the second opening through the square through hole.
