Description

Technical Field

[0001] This utility model relates to the field of wire and cable technology, and in particular to a steel strip coil lifting tool for cable armoring machines. Background Technology

[0002] Armored cables have an added armor layer on the outer sheath to increase the cable's mechanical strength and improve its corrosion resistance. Steel tape armored cables are produced by winding steel tape around the cable using a wrapping head. The steel tape used in production is usually purchased in rolls. During installation, the center hole of the steel tape roll is used as the hanging point. A hook passes through the center hole to lift the roll and moves it to the wrapping head. The center hole of the roll is then fitted onto the wrapping shaft, completing the installation. However, because the hanging point is at the center hole of the roll, the hook positioned at the wrapping head hinders the wrapping shaft from passing through the center hole, making loading the roll difficult, resulting in low work efficiency and high labor intensity. Summary of the Invention

[0003] The purpose of this utility model is to provide a steel strip coil lifting tool for cable armoring machines to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel strip coil lifting device for cable armoring machines includes a central ring, which is a circular steel plate with a through hole at its center. Two sets of drag rods are symmetrically fixed at the lower part of the central ring, with one end of each drag rod fixed to the central ring and the other end having a drag hook. A lifting rod is fixed at the top center of the central ring, with one end fixed to the central ring and the other end having a lifting ring. The middle section of the lifting rod has threads, and a limit nut one and a limit nut two are installed on the lifting rod through the threads. A sliding sleeve is slidably mounted on the lifting rod, and a pressure hook is provided on the side of the sliding sleeve. The limit nut one, the sliding sleeve, the pressure spring, and the limit nut two are sequentially pressed together. The drag hook and the pressure hook are used for positioning and fixing the steel strip coil.

[0006] The tow rod and the lifting rod are on the same plane.

[0007] The horizontal section of the tow hook and the horizontal section of the pressure hook are parallel to each other, and the horizontal sections of the tow hook and the pressure hook are perpendicular to the tow rod and the lifting rod. The length of the horizontal sections of the tow hook and the pressure hook is greater than the width of the steel strip.

[0008] The diameter of the through hole is larger than the diameter of the center hole of the steel strip and the diameter of the wrapping shaft.

[0009] During operation, the center of the lifting ring and the center of gravity of the steel strip are in the same vertical plane.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] The mounting and unloading operations of this utility model are simple and convenient, the hoisting is reliable and not easy to slip off; it is suitable for steel strip coils of different diameters; the mounting point is on the outer edge of the steel strip coil, which does not affect the insertion of the steel strip coil center hole into the wrapping shaft, resulting in high working efficiency; the structure is simple and the manufacturing cost is low.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] like Figure 1-3As shown, this utility model provides a steel strip coil lifting tool for cable armoring machines, including a central ring 1, a through hole 2, a drag rod 3, a drag hook 4, a lifting rod 5, a lifting ring 6, a first limiting nut 7, a sliding sleeve 8, a pressure hook 9, a second limiting nut 10, a compression spring 11, and a steel strip 12. The central ring 1 is a circular steel plate with a through hole 2 in its center. One end of the drag rod 3 is fixed to the central ring 1, and the other end of the drag rod 3 is provided with a drag hook 4.
