Description

[Detailed description of the invention]

[0001]

The present invention relates to a method for removing a suspension line extending from a utility pole to a utility pole in order to lay a communication cable such as a telephone cable. The present invention relates to a gold wheel used for dragging guidance.

[0002]

2. Description of the Related Art There has been no wheel train used for removing a suspension line with a cable ring. cable·
Ordinary wheels that are used for the extension or removal of wires or the like to guide the wires are constructed by rotatably supporting a grooved vehicle on a suspension frame.

[0003]

Conventionally, a suspension line with a cable ring has been removed from the terminal in the entire removal section by sequentially dropping to the ground every one pole (span), and the cable ring is removed from the suspension line on the ground of the corresponding span. The hanging wire is repeatedly cut into one span lengths and processed into a looped bundle.

[0004] However, there are many places where work is difficult due to the terrestrial environment (eg, water fields, rivers, shopping streets, traffic obstructions, etc.), which is a problem. To establish a new removal method to solve the problem, a special wheel was required.

In the new removal method, a pulling wheel is attached to all pillars in a removal section, and at the same time, a suspension line with a cable ring is transferred to a pulling wheel, one end of the suspension line is pulled by a towing machine, and the entire removal section is cabled to the suspension line. Pull out all at once with the ring attached,
At the same time, the suspension line attempts to process the entire section into one bundle.

[0006] Conventionally, all relied on human power. However, according to the above-mentioned new removal method, since large-scale mechanization can be performed, it is expected that both the number of operating personnel and the required time will be reduced by half.

[0007] The required wheel for this purpose is too small with the existing wheel and the suspension line with the cable ring cannot be passed through. However, simply increasing the size of this pulley results in a pulley having a diameter of about 10 times, a width of about 5 times, and a weight of about 5 times, so that practical use cannot be expected in terms of workability, transportability, storage, and cost. For this reason, the present invention has been devised to obtain a light and small gold wheel that can be pulled through with the cable ring attached.

[0008]

Means for Solving the Problems The wheel of the present invention has the following configuration to achieve the above object . You
In other words, the support shaft that extends between the side frames facing each other of the substantially gate-shaped hanging frame is bifurcated radially outward.
A plurality of Y-shaped arm members are provided radially at substantially equal intervals.
The rotating body is freely rotatable and one of the side frames can be opened and closed.
And each of the Y-shaped arm members has a bifurcated portion.
It is characterized by having a car .

[0009]

Function The wheel of the present invention is mounted at an arbitrary height on a utility pole, and the hanging wire with a cable ring attached to the utility pole with a hanging wire is removed and replaced with a wheel. If you handle one end of the suspension line,
The suspension line enters the forked portion of the Y-shaped arm member and moves while rotating the pulley while being supported by the wheel. When the cable ring attached to the suspension line hits the front Y-shaped arm member, the wheel rotates, the cable ring enters between the front and rear Y-shaped arm members, and then touches the front Y-shaped arm member to remove the wheel. It pushes out and goes out between the front and rear Y-shaped arm members, during which the suspension line does not come off from the Y-shaped arm member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of an embodiment of the suspension wheel with a cable ring of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the entire structure, in which gate-shaped hanging frames 1 are opposed to each other.
The support shaft 2 is passed between the lower ends of the side frames 1A and 1B. One end of the support shaft 2 is fixed to one side frame 1A by welding or the like as shown in FIG. The other side frame 1B is
The upper end is attached to the end of the horizontal frame 1C by the horizontal pin 3 and can swing as shown by a chain line 1b. The hole 4 at the lower end of the side frame 1B is loosely fitted to the other end of the support shaft 2. As its fit waited side frame 1B to the support shaft 2 does not come off from the support shaft 2 swings outwardly or disconnect pin 5 penetrating the 1B1 part of the end and side frame 1B of the support shaft 2 in the radial direction of the support shaft 2 It has. Its insertion and removal pin 5, knob wheels 6 are attached to the knob wheel 6, a chain for loss prevention fixed at an appropriate position of the lower frame 1 hanging one end
(Not shown) can be connected. At the center of the upper surface of the horizontal frame 1C of the hanging frame 1, there is provided a mounting portion 1D having a bolt through hole 1H for mounting the hanging frame 1.

A tube shaft 7 as a rotating body is rotatably fitted on the outer periphery of the support shaft 2. And the outer periphery of the boss portion 7A which is formed in the center of the tube axis 7, two radially outwardly
Several double branched crotch shape (illustrated case five) Y-shaped arm member 8 is attached at equal intervals radially. The bifurcated portions 8A of the respective Y-shaped arm members 8 are arranged intermittently in the circumferential direction.
The two rows of the forked portions 8A form a single groove in the circumferential direction. Also at the bottom of each of the bifurcated portions 8A <br/> pulley 9 is mounted.

FIG. 3 shows a state of use of the wheel & pinion K according to the present invention. The hanging wire with the cable ring is removed from the hanging wire fitting attached to the telephone pole 10, and the bracket 11 is attached to the hanging wire fitting. The bracket 11 is attached to the electric pole 10 at an arbitrary height by a belt 12 or the like, and the wheel K of the present invention is attached thereto.

[0013] The suspension wire cable ring with hanging line D, which has been stopped in the bracket, one of the side frame of the lower frame 1 hanging of the gate-shaped 1
B is inserted into the inside of the frame 1 from the gap formed by opening B, and is hooked on the forked portion 8A of the Y-shaped arm member 8. Side frame 1
Close B, side frame 1B and supported through insert pin 5 to the support shaft 2
Stop lifting shaft 2 (see FIG. 2). The suspension line D is shown in FIG.
Pull the Oite right, the catenary D second Y-shaped arm member 8
Since Tsu mounting the crotch portion 8A move while turning the pulley 9,
When the cable ring R hits the Y-shaped arm member 8 on the front side, the wheel K rotates, and the cable ring R is connected to the front and rear Y-shaped arm members 8.
8 and then touching the front Y-shaped arm member 8 and pushing out the wheel while turning out of the space between the front and rear Y-shaped arm members 8.8 , the suspension line D is a forked portion 8A. There is no departure from.

[0014]

[Effect of the invention The present invention cable ringed catenary mold vehicle according to, as described above, mutual suspension frame in a substantially gate shape
A support shaft passed between the side frame opposite to, the two radially outward
A plurality of Y-shaped arm members branched in a crotch shape are radially almost equally spaced
The rotating body provided at a distance is freely rotatably supported, and the side frame
Is openable and closable, and each of the Y-shaped arms is
Since the forks were provided with pulleys at the fork , the wheel could be made much smaller and lighter, making it practical for workability, transportability, storage and cost. Therefore, there is an effect of eliminating the trouble of removing the cable ring from the suspension line beforehand when removing the suspension line with the cable ring, thereby improving the work efficiency.
