Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present application mainly relates to a gold wheel used when constructing a communication line or the like, and particularly to a hook portion for locking the communication cable or the like.

[0002]

[Problems to be solved by the device]

 When the above-mentioned locking hook is hung on the support wire stretched above the communication cable or the support wire and the cable are integrated (SS cable), a particular problem occurs if the installation state is horizontal. However, there are still problems to be solved when constructing on a sloping ground. In other words, in the horizontal state, the soft material is lined for a predetermined time in the curved part of the hook part of the locking hook to form a two-step groove in which the center of the V-shaped bottom of the integrally-formed substantially V-shaped groove is further narrowed. Due to the frictional resistance of the formed suspension part, the supporting wire is maintained in a fitted state, and the gold wheel does not move. However, the erection site is not only horizontal, but the support wires W and cables C are erected substantially parallel to the ground. Therefore, in the communication line erection work on a sloping ground, gold cars arranged at even intervals are in contact with each other. It may slip to the side and the distance may not be maintained, and the new line may hang down in places where there are wide distances between trains, which may cause injuries to pedestrians on the way, or may drop down to the ground and damage the new line. It was In addition, depending on the situation, even on a level ground, when a communication line with tension applied to the wire passes over the cable holding roller at the lower part, which is integrally connected, the car itself gradually vibrates due to vibrations and the like. Sometimes I started moving.

[0003]

[Means for Solving the Problems]

 In order to solve the above problems, in the present application, a pair of projecting frames 15 are provided on the side walls of the cap operating piece 5 of the locking hook 2, and the corrugated plate member 16 is fixed to the tip of the frame 15. A pressing plate 18 to which a soft rubber plate 17 is attached is provided on the surface of the corrugated plate member 16. Therefore, when locked by the support wire, the pressing plate 18 presses the cable from below, causing frictional resistance between the soft rubber plate 17 attached to the surface of the pressing plate 18 and the soft material on the cable surface, and for locking. By the frictional resistance between the support wire W and the thin groove in the center of the V-shaped bottom of the hook 2, the movement of the gold wheel on the support wire is prevented as much as possible.

[0004]

[Prior art]

 As shown in Utility Model Registration No. 300952, a cable erection wheel that has been conventionally used is one in which a hook portion for locking a support wire or the like is connected to the upper portion and a cable holding roller portion is connected to the lower portion. The operation was performed from the ground to remove the wire from the support wire, and to open and close the line-holding protrusion on the holding roller. This operation from the ground is performed with a telescopic operation rod, and a roller that supports one end of the holding roller shaft by operating the cap opening ring that is continuous with the opening and closing cap of the hook to hang it on the support wire. By operating the open part, the line holding space can be opened and the new line can be removed from the roller part. Therefore, there is no means for surely preventing the movement when locked on the inclined line.

[0005]

[Form of actual state of invention]

 In the present application, the locking hook 2 is provided with a movement preventing means at the time of locking to hold the locking position of the supporting wire and the cable on a sloping ground, and the cap operating piece 5 of the locking hook 2 is held. A pair of projecting frames 15 are provided on the side walls of the plate, a narrow corrugated plate member 16 is welded to the tip of the frame 15, and a pressing plate 18 having a soft rubber plate 17 attached to the surface of the corrugated plate member 16 is provided. The pressing plate 18 has a pressing force with respect to the direction in which the locking hook 2 rotates about the support wire W (arrow A in FIG. 5) and the inclination of the locking hook due to the sloping ground (arrow B in FIG. 6). ) The pressing force is applied by the lever action, resulting in a strong friction resistance. If the cable is further extended, the weight is added and the support wire W strongly enters into the inverted V-shaped narrow groove 22, increasing the frictional resistance between the pressing plate 18 and the cable C, and the force causes the cap operating piece to move. 5 is pressed by the locking pin 24, the opening / closing cap 4 does not open unintentionally, and a safe and reliable locking hook can be obtained.

【Example】

 To describe the embodiment of the present application in detail, as shown in the drawing, a hook-shaped locking hook 2 is formed of a plate material. At the base end of the hook 2 for locking, a link 3 is provided with a hole for connection so that the cable holding roller 7 can be connected to the lower part. The hook of the locking hook 2 part is always closed by the opening / closing cap 4.The cap 4 is connected to one end of the cap operating piece 5 so that both sides of the central portion of the cap operating piece 5 are connected. A pair of projecting frames 15 are provided on the front side of the projecting frame 15, and a narrow corrugated plate member 16 is welded and arranged at a right angle to the projecting frame 15 (parallel to the cap operating piece 5). A plate 17 is attached and a pressing plate 18 is provided. The other end is supported by the locking pin 24 on the hook main body side, and by operating the cap opening / closing ring 6 provided at the end with the operating rod P, the interlocking open / close cap 4 is rotated and the hook is opened. Will be opened and closed. A cable holding roller portion 7 connected via a link 3 has a holding roller 9 pivotally fixed between tip ends of a substantially U-shaped roller frame 8 whose base ends are superposed and connected. One end of the roller frame 8 is separated and the one end of the roller shaft 91 is fixed to a rotatable frame piece 82 connected by a hinge 81, and the other roller frame 8 is U-shaped from the bottom to the tip. -Shaped notch 83 is provided, and the other end of the roller shaft 91 is accommodated in the notch 83. The shaft in the notch 83 is supported by a hook piece 11 at one end of a shaft supporting member 10 which is pivotally supported by the roller frame 8. The other end of the shaft support member 10 is a curved operation piece 12, which is operated by the tip of a telescopic operation rod P from the ground. In other words, the center of the shaft support member 10 is pivotally supported by the roller frame 8, and when the operation piece 12 is pushed down, the hook piece 11 rotates to release the support of the roller shaft 91, so that the holding roller 9 becomes the other roller. The cable on the holding roller 9 is released by rotating the hinge 81 of the frame 8. The main structure of the present application is that a cable pressing plate 18 is provided near the hook opening of the hook portion 1 of the locking hook 2, and when the cable pressing plate 18 is suspended on the supporting wire W and the cable C, the cable C is pressed by the pressing plate 18. It is pressed from below to prevent the locking hook 2 from moving (sliding) to the valley side.
