[Structure] A pair of roller bases 5 having a plurality of rollers 6 for rotatably supporting the discs 22 at both ends of the cable drum 2, and at least one of the front and rear parts of the roller bases 5 is detachable or attachable. Adjustablely mounted drum detent frames 7,8.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable drum turntable that enables rotation of a cable drum when a cable is extended from the cable drum.

[0002]

[Prior Art]

 Conventionally, when a cable is extended from a cable drum, a steel pipe is passed through a hole in the center of the cable drum, the steel pipe is placed on a pedestal, and the cable drum is supported on the steel pipe and floated to rotate the cable drum. Is possible.

[0003]

[Problems to be solved by the device]

 Although the conventional cable drum rotating means is as described above, there are problems that the rotation is not smooth and that the pedestal may tip over if the cable is strongly pulled from the wire extension side.

The present invention was made in order to solve the above problems, and an object thereof is to obtain a cable drum turntable that smoothly rotates and does not fall over.

[0005]

[Means for Solving the Problems]

 The cable drum turntable according to the present invention comprises a pair of roller bases having a plurality of rollers for rotatably supporting the discs at both ends of the cable drum, and at least one of the roller bases is attachable to and detachable from the front and rear portions of the roller base. It is provided with a drum detent frame that is mounted so that the mounting position can be adjusted.

[0006]

[Action]

 Discs at both ends of the cable drum are placed on a pair of roller bases of the cable drum rotary base in this invention, and a drum stopping frame is attached to the front and rear parts of the roller base to extend the cable from the cable drum. If the wire is drawn, the cable drum is subjected to a pulling force and a rotating force, but since the discs at both ends of this cable drum rest on the rollers of the roller stand, this roller freely rotates this cable drum. Further, the drum retaining frame prevents the cable drum from moving out of the roller stand, which tends to move due to the pulling force of the cable.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 2 is a cable drum, 22 is a disk at both ends of the cable drum 2, 3 is a cable, 5 is a roller base, 6 is a roller, 7 is a front drum stop frame, and 8 is a rear drum stop frame. It is the body. The pair of roller bases 5 has a structure like a roller conveyor, and a large number of rollers 6 are provided so as to be exposed on the upper surface of the roller bases 5. The front drum stopping frame 7 has a height equal to or larger than the radius of the drum end disc 22 and has an L shape or an inverted T shape, and is attached to the front portion of each roller base 5 by the attachment bolts 75. Be done. The hole 7h through which the mounting bolt 75 at the base of the front drum stop frame 7 is inserted is an elongated hole. The rear drum stop frame 8 also has the same shape as the front drum stop frame 7, and is detachably attached to the rear portion of each roller base 5 by the attachment bolts 85.

Next, the operation will be described. As shown in FIG. 1, a pair of roller bases 5 of this cable drum rotary base are arranged in the extending direction to the left and right at the same intervals as the width of the cable drum 2, and the discs 22 at both ends of the cable drum 2 are arranged thereon. The front drum stop frame 7 is attached to the front part of each roller base 5 with the mounting bolts 75, and the rear drum stop frame 8 is attached to the rear part with the mounting bolts 85. Since the hole 7h of the mounting bolt 75 for mounting the front drum stop frame 7 is a long hole, the mounting position of the front drum stop frame 7 can be adjusted in the front-back direction (left and right in the figure). Yes, the position of the front drum detent frame 7 is set according to the diameter of the discs 22 at both ends of the cable drum 2. Now that the wiring is ready, the cable 3 is extended. Then, due to the drawing tension of the cable 3, a pulling force to the right in the figure and a rotational force in the clockwise direction in the figure are applied to the cable drum 2. Since both end discs 22 of the cable drum 2 are placed on the rollers 6 of the roller base 5, the rollers 6 rotate the cable drum 2 freely. Further, the front drum stop frame 7 prevents the cable drum 2, which is about to move due to the pulling force of the cable, from deviating from between the front and rear drum stop frames 7 and 8 on the roller base 5. . Thus, the cable drum 2 freely rotates and unwinds the cable 3 on the roller base 5 by the wire drawing force without falling or deviating.

As shown in FIG. 1 (C), when a roller 9 such as a roller conveyor is provided on the front drum stop frame 7, a pulling force of the cable 3 causes both end circles of the cable drum 2 to move. When the plate 22 comes into contact with the front drum stopping frame 7, the frictional force between the discs 22 at both ends of the drum and the front drum stopping frame 7 becomes rolling friction resistance of the roller 9. The size of the cable drum 2 is reduced, and the smoothness of rotation of the cable drum 2 is more reliably maintained.

In the above embodiment, the front drum stop frame 7 is attached to the roller base 5 so that the mounting position can be adjusted, and the rear drum stop frame 8 is detachably attached. The drum stop frame 7 may be fixed to the roller base 5, and the rear drum stop frame 8 may be attached to the roller base 5 in a detachable and adjustable mounting position.

[0011]

[Effect of the device]

 As described above, according to the present invention, the rollers of the pair of roller bases freely rotate the cable drum, and the drum stopping frame prevents the cable drum from deviating, so that the cable drum rotates smoothly, A cable drum turntable that does not fall over can be obtained.
