DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 A super wear-resistant port machinery lifting pulley comprises an axle 1, both sides of the axle 1 are rotatably connected with a wheel body 2, the inside of the wheel body 2 is slidably connected with a connecting rod 3, one end of the connecting rod 3 is fixedly connected with a control block 4, one side of the control block 4 is slidably connected to the wheel body 2, the outer side of the axle 1 is rotatably connected with an adjusting ring 5, one side of the adjusting ring 5 is meshingly connected with an adjusting component, and the adjusting component can drive the control block 4 to slide left and right.

[0024] The adjustment assembly includes an adjustment gear 601 , one end of which is fixedly connected to a transmission sleeve 602 , and the other end of the connecting rod 3 extends into the interior of the transmission sleeve 602 and is threadedly connected to the transmission sleeve 602 .

[0025] The working principle of this embodiment is as follows: when using the lifting pulley, the rope is inserted into the notch on the side wall of the control block 4. When the rope slides, it will be controlled by the notch on the control block 4 to prevent the rope from sliding left and right and rubbing against the side wall of the wheel body 2, thereby providing good protection for the wheel body 2 and improving its wear resistance.

[0026] When the diameters of the ropes are different, the position of the control block 4 can be adjusted. During adjustment, the adjusting ring 5 is rotated, and the adjusting ring 5 drives the adjusting gear 601 to rotate. The adjusting gear 601 drives the transmission sleeve 602 to rotate, and the transmission sleeve 602 drives the connecting rod 3 to move to the side away from the adjusting gear 601, so that the connecting rod 3 pushes the control block 4 to move to the side away from the adjusting gear 601, and then the gap is shortened by the two control blocks 4 approaching each other, so that a rope with a smaller diameter can be adapted. When the adjusting ring 5 is rotated in the opposite direction, the two control blocks 4 will be driven to move to the opposite side to increase the gap. At this time, a rope with a longer diameter can be inserted between the two control blocks 4. By flexibly adjusting the left and right positions of the control blocks 4, ropes of different diameters can be adapted, thereby improving the applicability of the control blocks 4.
