JP3051047U - Cable erection wheel - Google Patents

Abstract

(57) [Summary] [Problem] In a structure in which a cable on a holding roller is detached by a natural fall by turning the roller downward, a bounce of a cable erection wheel is large due to a recoil when the cable is detached. This caused the gold wheels to move, increasing the distance between the wheels and causing new cables to hang, causing harm to pedestrians and disrupting ground traffic. SOLUTION: In order to detach a new cable, one of the substantially inverted U-shaped frames of the holding roller is opened, and the entire wheel is lifted again by the operating rod, removed from the support wire W, and then removed from the opening. It is a detachable structure that does not generate bounce.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present application relates mainly to a wheel train used when erection of a communication line or the like, and particularly to a roller portion for holding a communication cable or the like.

[0002]

[Prior art]

 A conventionally used cable erection wheel has a hook portion for locking to a support wire or the like and a holding roller portion for a cable or the like connected to a lower portion as shown in Utility Model Registration No. 2510626. In this case, the wire was detached from the support wire W by an operation from the ground, and the line holding space on the holding roller was opened and closed. This operation from the ground is performed by a telescopic control rod, and a ring connected to the opening and closing piece of the hook is operated to detach from the support wire and to support one end of the shaft of the holding roller. By operating the roller opening section, the line holding space was opened, and the new line could be removed from the roller section.

[0003]

[Problems to be solved by the invention]

 The above-mentioned holding roller (pulley) pivots downward and drops the new cable naturally and removes it from the holding roller. If the cable is thin (light), there is no particular problem. However, if the cable was thick (heavy), the problem remained. In other words, the new cable is installed and then the cables are sequentially removed. The thick (heavy) cable has a large recoil when it is removed, and the support wire bounces and the next wheel of the cable falls down. Moved forward due to weight, and where the wheelchairs are wide open, the new cable dropped drops further, causing harm to pedestrians, obstructing ground traffic, and hanging down to the ground to damage the new cable. It was conceivable to receive it.

[0004]

[Means for Solving the Problems] In order to solve the problems as described above, instead of a conventional structure in which a holding roller (pulley) is rotated downward and a cable is naturally dropped, the holding roller is not used. The frame is open on one side and does not fall naturally. That is, the cable is on the holding roller, and the entire wheel is lifted again by the telescopic rod and removed from the support wire W, and then the cable on the holding roller is slowly opened. It is a detachable structure that does not generate a bounce.

【Example】

 The embodiment of the present application will be described in detail. As shown in the figure, a hook portion 1 for locking to a support wire W and a cable C by an operation from the ground with a telescopic operation rod P at an upper portion, and a rope and a lower portion at a lower portion. This is a cable erection wheel including a holding roller portion 2 for holding a cable C and the like. The holding roller portion 2 is provided with an attachment portion 32 for attachment to the locking hook portion 1 at the center of the horizontal frame 31 of the substantially inverted L-shaped fixed frame 3, and the roller 4 is rotatable at the lower end of the vertical frame 33. The roller shaft 41 is supported in a cantilevered state to form a substantially U-shape, and the end of the roller shaft 41 constituting the lower U-shape is fitted with a long hole 61 at one end and freely rotatably connected to the other end. The fitting protrusion 62 provided at the end is arranged so as to be able to fit into the slit 34 at the tip of the fixed frame 3, and one end of the support shaft 63 fixed at the intermediate portion is a contact piece 66 with the roller shaft 41, and the like. The end has a pressing piece 68 for pressing a spring 65 for maintaining the contact state, and a substantially T-shaped piece protruding from an intermediate portion of the two pieces and having a tip bent slightly upward at a substantially right angle. The opening / closing lid 6 is constituted by supporting the U-shaped operating piece 64, and the space above the roller is closed by the fixed frame 3, the roller 4 and the opening / closing lid 6. doing.

The locking hook 1 is connected to the holding roller 2 at the lower end of a support 7 having a vertically long shaft support hole 71 at the upper end. A lever rod 8 having a pressing portion 82 at the other end is pivotally supported 9, and the support 7 is inserted and accommodated in a slide space 10 provided at the base end near the pressing portion 82. Then, an intermediate portion of a hook member 12 having a hook-like portion 11 at its tip is rotatably supported by a shaft 13, and the lever 8 is rotated by the weight of the holding roller portion 2, and is hung over the support wire W and the cable C. The inside of the hook-like portion 11 and the pressing portion 82 of the lever 8 are gripped and fixed, and the swinging of the roller portion when the cable or the like is extended is performed by moving the shaft of the lever 8 in the vertically long shaft supporting hole 71 provided in the support 7. 9 and the hook member 12 connected thereto is operated by the slide space 10 without interfering with the movement of the support member 7, so that the support wire W and the cable The bull C has a structure that does not loosen the grip.

[0007] The method of using the cable erection wheel of the present invention is as follows: the tip of the operating rod P is fitted to the operating ring 81 as shown in FIG. A hook is formed between the hook 11 and the hook 11. In this state, when the support wire W and the cable C are further lifted and hung on the existing support wire W and the cable C, the support wire W and the cable C are gripped and fixed by the hook-shaped portion 11 and the pressing portion 82 of the lever 8 as shown in FIG. I do. In addition, a rope for wire drawing is put in the holding roller unit 2 in advance. As described above, a predetermined number of cable erection wheels are sequentially hung between the extending wire diameters, and then a new cable is connected to the rear end of the extending rope and pulled out. At this time, the swinging of the roller portion is supported by the shaft 9 of the lever 8 in the vertically long shaft support hole 71 provided in the support member 7 and the slide space 10 by the hook member connected thereto. Since it operates without interfering with the movement of the body 7, the holding and fixing of the support wire W and the cable C are not loosened. Next, when disconnecting the new cable, as shown in FIG. 6, the tip metal of the operating rod P is hung on the hook 67 and pulled down, so that the contact piece 66 rotates and comes off from the end of the roller shaft 41, and at the same time, the elongated hole. The opening / closing lid 6 is pulled down by 61, the upper fitting projection 62 is disengaged from the slit 34, and the opening / closing lid 6 rotates as shown in FIG. From this state, when the metal fitting of the operating rod P is fitted to the operating ring 81 again and lifted, the lever rod 8 rotates downward, and a hook hole is formed between the operating rod 81 and the hook-shaped portion 11. Can be removed. The new cable can be removed from the opening by removing the hook part 1 for locking and moving it in the lateral direction, thereby making it possible to remove the cable without bounce.

[0008]

[Effects of the Invention] As described above, by adopting the gold wheel of the present invention, the gold wheel can be operated from the ground, and the cable that does not cause bouncing can be removed. Therefore, the problem can be solved.
