[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rope connecting tool for a pole safety belt.

[0002]

[Prior Art]

 There are various types of pole work in the telecommunications field, such as cable retention, cable connection, and cable branching. In order to ensure that such work at heights can be performed safely and smoothly, a pole safety belt to protect the body of the worker from falling accidents and a pole work platform that is a foothold for the worker are provided. ing. However, even if the platform is used to secure the foothold, proper use of the pole safety belt is indispensable to ensure the safety on the pole. FIG. 6 shows the mounting state of the pole workbench and the standard mounting state of the pole safety belt 20. That is, the hook fitting 22 of the rope 21 is connected to the safety belt fitting 24 of the pole workbench 23, the other end side of the rope 21 is wound around the utility pole, and then the 8-shaped ring 25 at the tip thereof. To secure the safety by the main rope 21 first, and then connect the hook metal fitting 27 at the tip of the auxiliary rope 26 to the messenger 16 to connect the main rope 21. A double safety is ensured by the auxiliary rope 26 in order to cope with accidental disconnection, disconnection or accident.

[0003]

[Problems to be solved by the device]

 If the workbench is not equipped with the safety belt attachment 24, attach one end of the rope 21 to the messenger 16 on the opposite side of the utility pole as shown in FIG. To the messenger 16 in the open position, attach the bond metal fitting 28 that is originally used for grounding and bonding, and attach the hook metal fitting 27 of the auxiliary rope 26 to the outside of the bond metal fitting 28 to attach the auxiliary metal fitting 26. I was trying to reduce slippage.

However, the handling of the pole safety belt in which the auxiliary rope is used instead of the main rope by using the bond metal is to double the safety by using the main rope and the auxiliary rope. Considering that it deviates from the original purpose of securing it, and considering that the bond hardware is designed for ground connection, it is necessary to add weight to the worker, for example, cable connection work. It would be extremely dangerous if you do.

An object of the present invention is to provide a rope connecting tool for mounting a rope on a messenger without slipping the rope.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention inserts a moving side frame into a pulling side screw provided on a fixed side frame and sends the moving side frame to the fixed side frame. A cable is constructed so that a moving messenger frame is joined to and separated from a fixed side by the nut member for screwing together, and the messenger of the cable is sandwiched between these frames. In the bull suspension tool, lower portions of the fixed side frame and the movable side frame are recessed in mutually opposite sides in a V-groove shape to form a messenger holding portion, and either the fixed side frame or the movable side frame is formed. It is equipped with an annular metal fitting for connecting the hook of the rope for the safety belt on the pole.

[0007]

[Action]

 Since the messenger gripping groove has a V-shaped cross section, the tightening force of the screw and nut members is applied to the messenger on average. For this reason, sufficient frictional force is generated, and even if the weight is applied to the annular metal fitting through this rope, no deviation occurs, and there is no accidental disengagement. Safety is greatly improved.

[0008]

【Example】

 A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a rope connecting tool for a pole safety belt according to the present invention. Reference numeral 1 is a fixed-side frame formed in a semi-cylindrical shape, and 2 is a moving-side frame formed in a semi-cylindrical shape like the fixed-side frame.

At one end of the fixed side frame 1 in the circumferential direction, both ends thereof are curled outward as shown in FIG. 2 to form a first hinge part 3, and at the other end thereof is formed. Is extended along the radial direction to form a bolt mounting frame portion 4. The bolt mounting frame portion 4 is formed with a first notch 5 at the center in the width direction of the bolt mounting frame portion 4 from the tip end surface of the bolt mounting frame portion 4 toward the base side thereof. An annular hinge member 6 is integrally attached to the base portion side of the portion 4 at left and right symmetrical positions sandwiching the first notch 5. The hinge member 6 has a rod 7 rotatably inserted therein, and a male screw 8 is formed only on the outer periphery of the mounting side of the rod 7, and a wing nut 9 is screwed onto the male screw 8. The screw member 10 in the state is attached by welding. The external dimensions of the screw member 10 are appropriately smaller than the notch width of the first notch 5, and when rotated, the screw member 10 passes through the first notch 5 and is opposite to the bolt mounting frame portion 4. It is designed to rotate to the surface (inner surface) side.

On the other hand, a second hinge portion 11 is formed at one end of the moving side frame 2 on the base side in the circumferential direction by curling the center side portion outward as shown in FIG. A nut seating frame portion 12 is formed at the other end so as to extend along the radial direction. The nut seating frame portion 12 is formed with a second notch 13 having the same width as the first notch 5 at the center portion in the width direction of the nut seating frame portion 12 from the front end surface thereof toward the base portion.

The fixed side frame 1 and the movable side frame 2 are arranged such that the first and second hinge portions 3 and 11 are coaxially aligned, and both ends of an annular metal member 14 formed by bending them into a D shape. It is inserted in the rotation. The fixed side frame 1 and the movable side frame 2 have the same parts on the base side from the first and second notches 5.13, respectively, which are recessed outward along the width direction and are messenger-shaped. A grip groove 15 is formed. The cross section of each messenger-holding groove 15 is formed to have a substantially V-shaped cross section.

The handling of the rope connecting tool for the pole safety belt according to the present invention will be described.

First, the wing nut 9 is loosened, the screw member 10 is turned over to the outside of the fixed side frame 1, the moving side frame 2 is opened around the annular metal fitting 14, and the fixed side frame 1 and the moving side are moved. The CCP cable is accommodated in the frame 2 and the messenger-holding groove 15 is engaged with the messenger 16. After that, the moving frame 2 is rotated to the closing side, and the screw member 10 is rotated to the opposite inner side to completely tighten the wing nut 9. As a result, the rope connecting tool is integrated with the messenger 16. After that, the hook fitting of this loop is connected to the annular fitting 14.

The messenger-holding groove 15 of the rope connecting tool has a sufficient length with respect to the messenger 16, and applies a uniform and sufficient tightening force thereto. For this reason, frictional force is effectively generated, no displacement occurs even if the weight of the annular metal fitting 14 is applied, and since the cross section of the messenger-holding groove 15 is set to V, there is no possibility of disengagement. Compared to this, installation and safety are dramatically improved.

4 and 5, the fixed side frame 1 does not have the first cutout 5 and the screw member 10 is integrally fixed to the fixed side frame 1, while the second cutout 13 of the moving side frame 2 is fixed. Instead of this, an elongated hole 13a is formed, and the annular metal fitting 12 is rotatably supported on the upper side of the moving side frame 2.

That is, in this embodiment, the fixed side frame 1 and the moving side frame 2 are not configured to be hingedly connected to each other by using the annular metal fitting 14 as in the above-described embodiment, but the fixed side frame 1 is used. The other moving side frame 2 is rotatable with respect to the screw member 10 integrated with the screw member 10, and the moving side frame 2 is movable upward and downward with respect to the screw member 10 by the elongated hole 13a. is doing.

Therefore, for attachment to the messenger, after rotating the moving side frame 2 by 180 degrees with respect to the fixed side frame 1, the messenger holding groove 15 of the fixed side frame 1 is engaged with the messenger 16, and then the state is changed. The procedure is to rotate the moving side frame 2 to the original position while holding it, engage the messenger grip groove 15 with the messenger 16, and tighten the wing nut 9. Further, the mounting position of the ring-shaped metal fitting 14 is advantageous in the vicinity of the messenger 16 where the cable is not twisted as shown in FIGS.
