[0002] The cable-laying pulley is an indispensable auxiliary equipment in the laying of high-voltage cables. It provides important support for cable installation projects by protecting cables, reducing friction, increasing construction speed, and adapting to complex environments.

[0003] In order to facilitate the loading and unloading of cables in the closed space thereon, the wheel frame of the existing wire-laying pulley is often equipped with a flip-over cover assembly that can open the closed space. However, these cover assemblies are mostly locked and fixed by threaded components in the closed state, resulting in the need to tighten and loosen the threaded components multiple times when closing and opening the cover assembly, which is more troublesome to operate and use. In addition, after the cover assembly is loosened and unlocked, additional manual effort is required to flip it open, which further aggravates the trouble in operating and using the wire-laying pulley.

[0006] A horizontal bearing plate is welded to the top of the V-shaped extension plate, and an insertion frame is installed on the horizontal bearing plate by spring pushing and sliding. The insertion frame is a U-structure as a whole, and is composed of two horizontal support rods and a U-shaped connection frame welded to the tail ends of the two support rods;

[0007] The top end of the vertical support plate on the right side of the U-shaped wheel frame is rotatably connected to a V-shaped flip plate, and the head end of the V-shaped flip plate is symmetrically welded with two positioning sleeves. Under normal conditions, the protruding parts of the head ends of the two horizontal support rods are correspondingly plugged into the two positioning sleeves;

[0008] Two vertical hanging plates are welded at intervals on the bottom side of the right half of the horizontal bearing plate. Top shafts are installed on the two vertical hanging plates through spring pushing and sliding. The top shafts are laterally supported, and the head ends are in contact with the head end of the V-shaped flip plate that is flipped upright upward.

[0009] Furthermore, two ear blocks are welded on the long sides of the horizontal bearing plate at intervals on the left and right, the cross brace rod is pushed by a spring to slide through the two ear blocks, and the U-shaped connecting frame is slidably inserted into the horizontal bearing plate.

[0010] Furthermore, a hook is rotatably mounted on the horizontal bearing plate, a rotating shaft is welded to the bottom of the hook, and the rotating shaft penetrates and rotatably cooperates with the middle position of the horizontal bearing plate.

The V-shaped flip plate 102 is flipped down and opened, and the cables can be loaded and unloaded inside the U-shaped wheel frame 1. The head end of the V-shaped flip plate 102 is symmetrically welded with two positioning sleeves 1021. Under normal circumstances, the protruding parts of the head ends of the two horizontal support rods correspond to the two positioning sleeves 1021 for plugging and matching, so that the V-shaped flip plate 102 can be plugged and positioned in an upwardly flipped upright closed use state. Compared with the existing technology of using threaded components to lock and fix the V-shaped flip plate 102, this can save the trouble of tightening and loosening the threaded components for multiple turns when closing and opening the V-shaped flip plate 102, and the operation is convenient and time-saving.

[0038] Two vertical hanging plates are welded at intervals on the bottom side of the right half of the horizontal bearing plate 103, and top shafts 105 are slidably installed on the two vertical hanging plates through the pushing of springs.
