The second loop sheave group 5 connected to the loop car is a movable pulley, including a second sheave shaft and a plurality of second sheaves arranged on the second sheave shaft, and the circumferential outer wall of the second sheave has a second wheel groove. One end of the steel rope 4 is wound on the winch 6, and the winch 6 is installed on the steel structure below the pulley group base 2, and the crane 7 is placed on the outside of the pulley group base 2.

[0029] The first main support 8 and the second main support 9 are respectively mounted on either side of the sheave assembly base 2. A plurality of first steel rope slings 10 are arranged at intervals on the first main support 8, and a plurality of second steel rope slings 11 are arranged at intervals on the second main support 9. A first steel rope sling 10 and a second steel rope sling 11 are arranged on either side of the center of each sheave. A winch 6 is located on one side of the second main support 9, and is used to retract and extend the entire steel rope 4.

[0030] Each first rope pulley, the second rope pulley below the first rope pulley, and the first steel rope sling 10 and the second steel rope sling 11 on both sides of the first rope pulley constitute a group of winding structures. In this group of winding structures, the steel rope 4 passes through the second steel rope sling 11 from bottom to top and is wound around the first wheel groove of the first rope pulley, and then passes through the first steel rope sling 10 from top to bottom and is wound around the second wheel groove of the second rope pulley. After bypassing the second rope pulley, it passes through the second steel rope sling 11 of the adjacent group of winding structures from bottom to top again; the other end of the steel rope 4 is connected to the steel structure after bypassing multiple groups of winding structures in sequence; the first steel rope sling 10 and the second steel rope sling 11 are used to realize the locking and releasing of the steel rope 4, and the crane 7 is used to lift the multiple turns of steel rope 4 and the first rope pulley shaft wound on the first rope pulley.

[0031] In this embodiment, the sheave assembly base 2 and steel structure are existing equipment. The first sheave shaft has four coaxial first sheaves, the second sheave shaft has four coaxial second sheaves, four first steel rope slings 10 are evenly spaced on the first main support 8, and four second steel rope slings 11 are evenly spaced on the second main support 9. The first steel rope slings 10 and the second steel rope slings 11 have the same structure and are symmetrically distributed about the central axis of the first sheave shaft. A first steel rope sling 10 and a second steel rope sling 11 are symmetrically arranged on either side of the center of each first sheave. Specifically, the steel rope 4 emitted from the winch 6 first passes through the second steel rope sling 11 of the first group from bottom to top, then winds around the wheel groove of the first rope wheel of the first group, then passes through the first steel rope sling 10 of the first group from top to bottom, then winds around the wheel groove of the second rope wheel of the first group below, then passes through the second steel rope sling 11 of the second group from bottom to top, then winds around the wheel groove of the first rope wheel of the second group, then passes through the first steel rope sling 10 of the second group from top to bottom, then winds around the wheel groove of the second rope wheel of the second group below, then passes through the second steel rope sling 11 of the third group from bottom to top, and so on, until it winds around the wheel groove of the second rope wheel of the fourth group below, the tail end of the steel rope 4 is fixedly connected to the steel structure through the rope head lock 3, wherein the rope head lock 3 includes a pin connected to the tail end of the steel rope 4, and the pin is inserted into the steel structure. The steel rope 4 is retracted and released by the winch 6, so that the second looper pulley group 5 moves up and down with the looper car.

[0032] As a preferred embodiment, the first steel rope sling 10 and the second steel rope sling 11 both utilize a U-shaped clamp. The U-shaped clamp includes a U-shaped clamp and a bolt. The U-shaped clamp includes a connected U-shaped slot and two long, strip-shaped fixing rods. The steel rope 4 runs through the U-shaped slot. The first main bracket 8 and the second main bracket 9 each have multiple groups of mounting holes, each group having two mounting holes. The two fixing rods of each steel rope sling run through a group of mounting holes, and one end extending through the mounting hole is connected to a bolt. A hole is provided between the U-shaped slot and the main bracket for the steel rope 4 to pass through. By tightening and loosening the bolt, the size of the hole is changed, thereby achieving the locking and release of the steel rope 4.

[0033] Specifically, during the process of winding and releasing the steel rope 4, the U-shaped clamp is in a non-locked state so that the steel rope 4 can slide through the U-shaped slot. When the four coils of steel rope 4 wound on the four sheaves need to be lifted to the required height by the crane 7, the two sides of each coil of steel rope 4 are locked and fixed to the corresponding main body bracket by the first steel rope sling 10 and the second steel rope sling 11 on both sides, leaving space between the four coils of steel rope 4 and the four first sheaves so that the first sheave shaft can be lifted and removed by the crane 7. Figure 3-6 The figure shows the process in which the crane 7 lifts up the four coils of steel rope 4 and then lifts up the first sheave shaft and gradually moves it out.

[0034] As a preferred embodiment, the first main body bracket 8 and the second main body bracket 9 have the same structure.

[0035] As a preferred embodiment, the first main body bracket 8 and the second main body bracket 9 are welded to the sheave assembly base 2 .
