Description

Technical Field

[0001] This application relates to a lifting device, and particularly to a cable reel lifting device. Background Art

[0002] A cable reel is a flanged barrel around which various types of electrical and optical cables can be wound. The barrel of the reel has flanges attached to the top and bottom of the barrel, and each flange typically includes a circular opening through which a mandrel can be inserted to allow the reel to rotate by pulling on the cable, thereby unwinding the cable from the reel. However, the volume and weight of a reel loaded with cables generally do not allow it to be directly lifted manually by a single worker alone, and for convenience during transportation to prevent the increased workload of making multiple round trips, it is generally most appropriate to make a single transportation. This often requires a larger volume of cable reel to achieve the purpose, but the problems encountered during transportation still cannot be solved. Summary of the Utility Model

[0003] To solve the above deficiencies of the prior art, this application provides a cable reel lifting device that can achieve the transportation of large-volume and heavy cable reels.

[0004] To achieve the above object, the present utility model adopts the following technologies:

[0005] A cable reel lifting device includes a hook, a suspension rod, and a swing support mechanism;

[0006] The swing support mechanism includes a mounting plate, along the circumference of which at least two swing rods are arranged in an array. The upper ends of the swing rods are hinged to the mounting plate, and the hinge axis is consistent with the tangent direction of the mounting plate. Chutes are provided on the inner side walls of the swing rods, and claw jaws are provided at the lower ends of the swing rods, and the side surfaces thereof are in a wedge-shaped structure, with the inclined surface inclined upward toward the outside of the mounting plate;

[0007] The suspension rod coaxially and perpendicularly passes through the mounting plate. A sliding disc is coaxially provided below the suspension rod. Pulleys are arranged in an array along the circumference of the outer periphery of the sliding disc. The pulleys roll one by one in the chutes. The distance between the upper end of the swing rod and the axis of the mounting plate is greater than the distance between the pulley and the axis of the suspension rod. A hook is provided at the top of the suspension rod.

[0008] The beneficial effect of the present utility model is that when transporting a cable reel, the cable reel lifting device can make the suspension rod and the swing support mechanism move relative to each other by lifting with the hook to clamp the cable reel, so that a large-weight and large-volume cable reel can be stably lifted and transported; the arrangement of the one-to-one cooperation between the pulley and the chute can make the relative movement between the suspension rod and the swing support mechanism more controllable and adjustable, improving the stability of their cooperative work.

[0011] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0012] The embodiments of the present application provide a cable reel lifting device, as Figure 1 shown, which includes a hook 3, a swing support mechanism, and a boom 2. The swing support mechanism includes a mounting plate 1, which is provided with at least two swing rods 11 arranged in a circumferential array. In this embodiment, three swing rods 11 are adopted. The upper ends of the swing rods 11 are hinged to the mounting plate 1, and the hinge axis is consistent with the tangential direction of the mounting plate 1. Slide grooves 14 are provided on the inner side walls of the swing rods 11, and claw 12 are provided at the lower ends of the swing rods 11, and the side surfaces thereof are in a wedge-shaped structure, with the inclined surface inclined upward toward the outside of the mounting plate 1. The boom 2 coaxially and perpendicularly passes through the mounting plate 1, and a sliding disk 21 is coaxially provided below the boom 2. Pulley 13 are arranged in a circumferential array on the outer periphery of the sliding disk 21, and the pulley 13 roll in the slide grooves 14 one by one. The distance between the upper end of the swing rod 11 and the axis of the mounting plate 1 is greater than the distance between the pulley 13 and the axis of the boom 2. A hook 3 is provided at the top of the boom 2.

[0013] During use, lift the hook 3, and the hook 3 drives the boom 2 and the sliding disk 21 to move upward. The upward movement of the sliding disk 21 causes the swing rods 11 to rotate outward, and the rotation of the swing rods 11 drives the claw 12 to move synchronously. When the pulley 13 on the sliding disk 21 moves to the upper end point of the slide groove 14, there will be no relative movement inside the entire device. At this time, place the cable reel outside the cable reel lifting device, and the claw 12 clamps it at the bottom of the cable reel. Then continue to drive the entire device upward through the hook 3, and the cable reel clamped by the claw 12 will move along with the movement of the entire device, thereby achieving the purpose of transporting the cable reel.

[0014] When it is necessary to take out the cable reel after the transportation, first take out the cable reel from the outside of the device, and then use the method of manual knocking to move the boom 2 downward. The boom 2 drives the sliding disk 21 to move downward. When the pulley 13 of the sliding disk 21 moves to the lower end point of the slide groove 14, the sliding disk 21 descends to the lowest point it can reach, and there will be no relative movement in the entire device. At this time, the swing rods 11 and the claw 12 contract inward along the radial direction of the mounting plate 1.

[0015] Specifically, as Figure 1As shown, the jaw 12 is hinged to the lower end of the swing rod 11, and the axis of its hinge is parallel to the axis of the pulley 13. A limiting portion 121 is provided at the top of the rear end of the jaw 12. When the swing rod 11 is parallel to the suspension rod 2, the limiting portion 121 abuts against the inner side wall of the swing rod 11, and the bottom surface of the jaw 12 is perpendicular to the suspension rod 2. The limiting portion 121 is used to limit the downward rotation angle of the jaw 12 to ensure the structural stability of the jaw 12 when lifting the drum.

[0016] Specifically, as Figure 1 shown, a torsion spring is provided on the hinge shaft of the jaw 12. When the torsion spring is in its natural state, the limiting portion 121 abuts against the inner side wall of the swing rod 11, so that during the process of inserting the jaw 12 into the bottom of the cable drum, the bottom surface of the jaw 12 can always be kept in close contact with the ground, thereby enabling the jaw 12 to be inserted into the bottom of the cable drum more smoothly.

[0017] More specifically, an acute angle is formed between the upper end of the chute 14 and the upper end of the swing rod 11 to facilitate increasing the swing angle of the swing rod 11.

[0018] During application, as Figure 2 shown, the lifting hook 3 is lifted, and the lifting hook 3 drives the suspension rod 2 and the sliding disc 21 to move upward. The upward movement of the sliding disc 21 causes the swing rod 11 to rotate outward through the mutual cooperation of the pulley 13 and the chute 14. The rotation of the swing rod 11 drives the jaw 12 to move synchronously. When the pulley 13 on the sliding disc 21 moves to the upper end point of the chute 14, there will be no relative movement inside the entire device. Adjust the angle between the swing rod 11 and the jaw 12 so that the cable drum can be sleeved outside the cable drum lifting device, and the jaw 12 is clamped at the bottom of the cable drum. Then, continue to drive the entire device upward through the lifting hook 3. Due to the limitation of the limiting portion 121 at the top of the jaw 12, the jaw 12 will no longer rotate downward and plays a role in supporting the load, and the cable drum clamped by the jaw 12 will move along with the movement of the entire device, thereby achieving the purpose of transporting the cable drum.

[0019] The above are only the preferred embodiments of the present application and are not used to limit the present application. Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
