Abstract

(57) [Summary] [Purpose] To obtain a suspension part of a cable trolley that does not move on a support cable. [Structure] A substantially reverse V integrally formed by a lining process in which a soft material having a hardness of 50 to 70 is closely adhered to the hook portion 1 serving as a core material over a predetermined position of the bent position of the hook portion 1 of the locking hook 2.
It is formed in a two-step groove shape having a V-shape 21 and a substantially inverted U-shape 22 at the center of the V-shaped bottom. [Effect] The support cable is held and fixed in the U-shaped groove, and it does not become impossible to support the cable at equal intervals because it is closer to the center of the span or closer to the utility pole.
The cable does not hang down or get damaged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

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

[0002]

[Prior art]

 As shown in Fig. 5, the cable laying wheel that has been conventionally used has an upper part connected with a hook part for retaining a supporting wire or the like and a lower part with a cable holding roller 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 an expansion rod, and the cap opening ring 6 that is continuous with the opening and closing cap 4 of the hook is operated to hang it on and off the support wire, and the roller that supports one end of the shaft of the holding roller. The line holding space is opened by operating the opening portion.

[0003]

[Problems of the prior art]

 The cable trolley of the conventional example having the above-mentioned configuration has a problem when the cable is hung by being hung on the support wire. In the conventional type, the hook part of the locking hook was curved with a round bar and covered with a heat-shrinkable tube, but it was locked to the support wire and the cable was held in the lower cable holding roller part. When holding and extending the wire, the wagon itself sometimes moved on the support cable, which interfered with the construction. Although the support cable is stretched with some tension between the utility poles, it is unavoidable that the center part of the span becomes low, and the support cable on the lower cable holding roller, which is integrally connected, is installed. When the cable with tension applied to the wire drawing passes, the metal train itself gradually starts to move due to its vibration, etc. Therefore, the original position where the cable was supported at equal intervals in the span was placed. In contrast to this, the cable may not be able to support the cables at equal intervals because it may be closer to the center of the span or closer to the utility pole.Therefore, there was concern that the cable might hang down or the cable might be damaged by overtension. .

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, in the present application, a protection part made of soft rubber is provided at the contact position of the locking hook with the support cable, and a small groove for holding the support cable and fixing the position is provided. The configuration is adopted. Specifically, when suspended on a supporting cable, lining is performed with soft rubber so that the bottom of the hook has a substantially inverted V shape, and the V-shaped bottom has a smaller diameter than the support cable, approximately U. Provide a groove in the shape of a letter. Therefore, a hook portion having a two-step groove of V groove and U groove is obtained, and the support cable is guided by the V groove and enters the U groove. Therefore, the support cable is operated from the ground by the telescopic operation rod, and the support cable is gripped and fixed in the U groove even in an unstable or uncertain situation. Further, this V groove can obtain a strong gripping force even when it is locked to other thick cords whose diameter cannot be discriminated from the ground.

【Example】

 To describe an example of the present application, a hook-shaped locking hook 2 is formed of a plate material. At the base end of the locking hook 2 part, a connecting hole is provided to connect the cable holding roller part 7 to the lower part, and the connecting part 3 is connected. The connecting portion 3 is formed by abutting the substantially U-shaped back surfaces to each other and rotatably connecting them by a shaft. The hook of the locking hook 2 is always closed by the opening / closing cap 4, and the cap operating piece 5 is connected to the tip of the cap 4. The cap operating piece 5 is supported on the hook main body side, and by operating the cap opening ring 6 provided at the end, the interlocking open / close cap 4 is rotated to open / close the hook opening. The cable holding roller portion 7 connected via the connecting portion 3 has a holding roller 9 pivoted between the tip ends of a substantially frame-shaped roller frame 8 whose base ends are superposed and joined. One end of the roller frame 8 is separated and is connected by a hinge 81. One end of a roller shaft 91 is fixed to a rotatable frame piece 82, and the other roller frame is U-shaped from the bottom to the tip. A cutout 83 is provided, and the other end of the roller shaft 91 is accommodated in the cutout 83. A shaft 91 in the cutout 83 is supported by a hook piece 11 at one end of a shaft support member 10 provided so as to be pivotally supported on 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 the telescopic rod from the ground. That is, the center of the shaft support member 10 is 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 is On the other hand, by rotating the hinge 81 of the roller frame 8, the cable on the holding roller 9 is released. The gist of the present application is that the hook 1 of the locking hook 2 is lined with the soft rubber 24 in a predetermined shape. The space between the position where the locking hook 2 is slightly inserted from the tip of the hook 1 to the position where the cap operating piece 5 is supported is housed in the mold shown in FIG. Lining with quality rubber 24. The shape is a substantially inverted V-shape 21 along the bottom of the hook 1, and a groove 23 having a substantially inverted U-shape 22 is further provided on the groove bottom of the V-shaped bottom. The diameter of the U-shaped groove is 6 mm, but since the diameter of the supporting wire of the cable is 6.3 mm, this is a configuration for fixing the position on the supporting wire by the sliding contact resistance, which is the purpose of this application. is there . Although the soft rubber 24 is used in the present application, the same effect can be obtained by using another material such as urethane resin as long as the hardness is the same.

[0006]

[Action]

 The cable erection wheel with the above configuration is used. A messenger wire or the like is supported on the roller 9 of the cable holding roller section 7, and the cap release ring 6 is hung by the operating rod. If the cap opening ring 6 is lifted, the opening / closing cap 4 is rotated in conjunction with it, the hook is opened, and it can be locked to the support wire. In engaging the support wire, the support wire first comes into contact with the V-shaped groove 21, which serves as a guiding effect, and then fits into the U-shaped groove 23 at the bottom of the soft wire 24. Since the U-shaped groove formed by is slightly smaller than the wire diameter, it does not move while maintaining its position on the support wire. After the messenger wires have been deployed by sequentially lifting and locking them with the operating rod and arranging a specified number of them in the construction radius as described above, the cable is connected to the rear end to extend the wire. . When the wire drawing is completed, operate the roller opening part 13 of each gold wheel to take out the cable in the wire holding space 14, then operate the cap opening ring 6 to unlock the support wire and collect it. Is.

[0007]

[Effect of device]

 By adopting the present invention as described above, the support wire can be locked from the ground, and the locked position can be easily held. Since the soft rubber is used to maintain the locked position so that it can be operated from the ground, it is the simplest method and has a great economic effect.
