The present invention relates to a cable drum pedestal, and more particularly, a plurality of support rollers are provided between the bottom edge of the rotating plate on which the cable drum is substantially placed and the upper surface of the support plate, so that the cable drum is unwound when the cable is wound around the cable drum. The present invention relates to a cable drum pedestal so as to stably support and distribute an eccentric load of the cable so that the cable can be loosened smoothly.

As is well known, cables are generally wound and shipped on cable drums so that volume reduction and smooth unwinding are possible, and at construction sites, one end of the cable wound on the cable drum is pulled out to be used for construction.

In the related art, a dedicated pedestal for easily unwinding a cable wound on the cable drum is not provided in a ready-made form, and in the field, a cable drum pedestal of the form shown in FIG. 1 is manufactured by itself and used for electric work. .

However, the self-produced cable drum pedestal 2 has a support plate 10 ', a support shaft 20' installed at the center of the support plate 10 ', and the support shaft 20 as shown in FIG. ') Is installed in a structure spaced apart from the support plate 10', and includes a rotating plate 30 'on which the cable drum 100 is placed.

Here, the rotating plate 30 'is installed on the support shaft 20' through the rotating bush 31 ', so that the natural rotation is possible when the cable drum 100 is not placed.

However, when the cable drum 100 is seated on the rotating plate 30 'and the operator pulls one end of the cable, the load of the cable drum is biased to the edge portion, so that the smooth rotation of the rotating plate becomes difficult.

When the rotation of the rotating plate is reduced, the loosening of the cable drum is not made smoothly, the air supply field may cause a problem that the cable drum placed on the pedestal is detached from the rotating plate, or the cable drum pedestal placed on the cable drum is overturned.

In this field, in order to prevent such a phenomenon, the height of the support shaft is increased, and the volume of the support plate is made large, but it is not a fundamental solution, and when this volume is enlarged, it is not carried in a passenger car or the like with a narrow loading space. I can't.

An object of the present invention devised to solve the above problems is to provide a plurality of support rollers between the bottom edge of the rotating plate on which the cable drum is substantially placed and the upper surface of the support plate, so that the cable drum is eccentric when the cable drum is released. The present invention provides a cable drum pedestal for stably supporting and distributing loads.

The above object is achieved by the following configuration provided in the present invention.

Cable drum pedestal according to the present invention,

A support plate; A support shaft installed vertically in the center of the support plate; And a rotating plate installed on the support shaft in a state spaced apart from the supporting plate by a rotation bush to become a space in which the cable drum is seated.

A plurality of support rollers are arranged circumferentially between the bottom edge of the rotating plate and the upper surface of the supporting plate, and the eccentric load of the cable drum generated when the cable of the cable drum placed on the rotating plate is released is supported and dispersed by the supporting roller. It is characterized in that configured to implement a stable loosening of the cable wound on the cable drum.

In the above configuration, the support roller supporting the edge of the rotating plate may include, for example, a radial support roller provided with a roller bearing at the end of the arm and a caster support roller, wherein the radial support roller is formed of a support plate. The roller bearing provided at the end of the arm radially installed on the support shaft formed between the rotating plate is a form that supports the edge of the rotating plate.

And the caster-type support roller is configured to support the edge of the rotating plate, the caster is provided on the upper surface of the support plate facing the bottom edge of the rotating plate, or both of them circumferentially.

Hereinafter, with reference to the accompanying drawings it will be described in detail a cable drum pedestal proposed as a preferred embodiment in the present invention.

2A to 2C are exploded perspective views, perspective views, and cross-sectional views, respectively, showing an overall configuration in a state where a cable drum is placed on a cable drum pedestal according to an embodiment of the present invention, and FIGS. 3A and 3B are respectively views of the present invention; 4 is a perspective view and a cross-sectional view showing the overall configuration in a state where the cable drum is placed in the cable drum pedestal according to another embodiment.

Cable drum pedestal (1, 1 ') according to the present invention, as shown in Figures 2 to 3, the support plate 10 having a support function, and the support shaft 20 installed vertically in the center of the support plate 10 And, the disk drum 100 is mounted on the upper surface of the disk-like plate material, the support plate 20 is configured to include a rotating plate 30 installed in a state spaced apart from the support plate 10 a predetermined interval in common.

Here, the rotating plate 30 is installed to be rotatable about the supporting shaft 20 through the rotating bush 31 provided on the supporting shaft 20.

Meanwhile, in the present invention, in implementing such cable drum pedestals 1 and 1 ', a plurality of support rollers 41A and 41B are provided between an edge of the bottom surface of the rotating plate 30 and an upper surface of the support plate 10 formed at the bottom thereof. They are arranged circumferentially so that the edges of the rotating plate 30 are always supported by the support rollers 41A and 41B.

Here, the edge does not necessarily mean the outermost part of the rotating plate, but it means that a point where the rotation radius is largely spaced apart from the support shaft 20 as much as possible is preferable.

And, these support rollers are preferably arranged to form one circumference as shown in the drawings, but is not limited thereto, and may be arranged to form two or more concentric trajectories around the support shaft 20. Do.

On the other hand, as an installation form of these support rollers, as shown in Figs. 2a to 2c, the arms 41A-a are disposed radially around the support shaft 20 formed between the support plate 10 and the rotating plate 30. The roller bearing 41A-b is provided in the edge part of each said arm 41A-a, and the radial support roller 40A is provided, respectively. At this time, the arms (41A-a) is fixed in position and may be configured to rotate only the bearings (41A-b), but preferably can be rotated about the support shaft 20 to allow the bearing (41A-) b) Ensure that the rotation is smooth.
