Abstract

(57) [Summary] [Purpose] To reduce the bulk and improve the handling. [Constitution] Opening / closing cap 3 for opening / closing the hook 2 of the locking hook portion 1 is provided with a tip of a cap operating piece 4 rotatably at the tip thereof, and a cap opening ring 5 is turned at the base end of the cap operating piece 4. The locking hook portion 1 and the holding roller portion 7 are connected by a connecting belt 18 while being freely provided. [Effect] The bulk is reduced, and the packing case can be made smaller, which facilitates transportation. It also improves the handleability.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present application mainly relates to a gold wheel used when constructing a communication line or the like.

[0002]

[Prior art]

 As shown in Figs. 4 and 5, the cable laying wheel that has been used in the past has a hook part for locking support wires etc. on the upper part and a cable holding roller part on the lower part. The operation was to hang it on and off the support wire and to open and close the wire holding space on the holding roller. This operation from the ground is performed with the telescopic rod, and the cap opening / closing ring 5 that is continuous with the opening / closing cap 3 of the hook is operated to hang it on the support wire and to support one end of the shaft of the holding roller. The line holding space was opened by operating the roller opening part.

[0003]

[Problems to be solved by the device]

 In the conventional cable erection wheel with the above-mentioned configuration, the cap opening ring protrudes, and the connecting metal fittings that connect the locking hook portion and the lower holding roller portion are substantially U-shaped back to back. Since they were abutted against each other and rotatably connected by a shaft, they were bulky and poor in handleability to carry dozens of wagons suspended in the construction span. In addition, the fact that the hook part and the holding roller part are rigidly connected means that when there is a bend in the construction radius, when tension is applied to the wire, the hook part will have a certain angle more than when it is suspended from the support line. The left and right sides of the roller, the extended line moves not to the center of the valley of the roller but to the frame sides on both sides, and in extreme cases, the line may come into contact with the frame and cause damage. It was seen to receive.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the protruding cap opening ring is of a bent type, and the connection between the upper hook part and the lower holding roller part is of the belt type to increase flexibility and reduce bulk. To improve handleability.

[0005]

【Example】

 To describe an example of the present application, it is composed of a hook-shaped locking hook portion 1 arranged on the upper portion and a cable holding roller portion 7 arranged on the lower portion, and the locking hook portion 1 opens and closes the hook port 2. It is always closed by the opening / closing cap 3, and a cap operating piece 4 is rotatably connected to the tip of the cap 3. The cap operating piece 4 is supported on the hook main body side, and by operating the cap opening ring 5 provided at the end, the interlocking open / close cap 3 is rotated to open / close the hook opening 2. The cap opening ring 5 is rotatably attached to the end of the cap operating piece 4 and is provided as a rotation stop at the end of the cap operating piece 4 through the spring pin 6 to prevent the cap opening ring 5. It is designed so that 5 does not rotate upward from a substantially horizontal position. The lower cable holding roller portion 7 pivotally supports the holding roller 9 between the tips of the inverted U-shaped roller frame 8. One end of the roller frame 8 is separated, the one end of the roller shaft 12 is fixed to a rotatable frame piece 11 connected by a hinge 10, and the other end of the roller frame has a U-shape from below. A notch 13 is provided, and the other end of the roller shaft 12 is accommodated in the notch 13. The shaft 12 in the notch 13 is supported by a hook piece 15 at one end of a shaft support member 14 which is pivotally supported by the roller frame 8. The other end of the shaft support member 14 is a curved operation piece 16, which is operated by the tip of the telescopic rod from the ground. That is, the center of the shaft support member 14 is pivotally supported by the roller frame 8, and by pushing down the operation piece 16, the hook piece 15 rotates to release the support of the roller shaft 12, so that the holding roller 9 is the other roller frame. It is rotated by 10 hinges of 8 to release the cable on the holding roller 9. To connect the locking hook part 1 and the cable holding roller part 7 described above, a hole is provided at the lower end of the hook part, one end of the connecting metal fitting 17 is axially attached, and both end parts of the belt are folded back inside to overlap. Then, the center portion is sewn, one end of the connecting belt 18 provided with ring portions at both ends is pivotally attached to the other end of the connecting fitting 17, and the other end of the connecting belt 18 is provided at the U-shaped bottom of the roller frame 8. The fitting shaft 19 is fitted in and connected.

[0006]

[Effect of device]

 By adopting the present invention as described above, the bulk can be reduced and the transportation becomes easy. In addition, the handleability is improved, and even if there is a bend in the diameter of the drawn wire, the wire being drawn is not damaged.
