Description

Wire Gripper and Wire Pole Supporting Wire with It {A Wire Gripper and An Electric Pole Supporting Wire Theirof}

The present invention relates to a support wire for supporting poles, in particular, a distribution pole, and more particularly, to a wire gripper and a branch wire using the same, which can conveniently and firmly connect the intermediate pole for supporting poles.

The conventional ground wire for preventing the collapse of the electric pole of the distribution is a ground wire that connects the ground wire buried in the ground from the top of the pole pole has a structure in which the insulator for the steel wire and insulation and the ground rod for fixing the ground value is connected. At this time, the part for connecting to the upper part of the pole and the part for connecting with the insulator connection part and the branch wire rod are used to wrap the wires by overlapping the wires by releasing the rigidity used as the branch wire to be joined by manpower during the construction of the site, or by using the connecting sleeve come. To this end, although it takes a lot of construction time, it has been difficult to secure a strong bonding force.

As shown in FIG. 1, the conventional branch wire has a hook that is coupled to the upper branch connection part provided at the upper side of the pole, and the insulator for insulator and the lower side fixing branch wire rod are connected to the lower side through the steel wire, The floor is provided and buried in the ground floor.

Here, the state of connecting the wire to the hook, insulator or branch rod is shown in a state in which the wires are unwound and rolled up. A method of using the sleeve for connection is also disclosed as an improved method, but the drawing is omitted.

In order to solve the difficulties in connection construction in the field as described above, the present invention is to provide a new type of wire gripper and branch line using the same. In particular, the present invention is to provide a wire gripper that can be firmly coupled to the stranded steel made of a twisted strand of several strands commonly used for branch lines. This aims to reduce construction time, manpower and cost for branch work on site, and to reduce the risk of industrial accidents.

In order to achieve the above object, the present invention includes an improved wire gripper. More specifically, it consists of a pair of upper and lower bodies facing each other, the inner surface of the lower body (or upper body) is formed with a groove of the 'X' plane so that two rows of seating grooves where steel wire is seated intersect at the center The inner surface of the upper body (or lower body) has two rows of protrusions formed in corresponding shapes along the seating groove, and is seated by the protrusions of the upper body in a state in which wires cross the seating grooves of the lower body. It characterized in that it comprises a fastening means for binding by pressing the wire seated in the groove.

The present invention also aims to provide an intermediate branch wire in which the above-described wire gripper is employed at one end or both ends.

According to the configuration features as described above, the present invention is expected to reduce the construction time, manpower and cost of branch line construction while providing a firm grip. In addition, it is expected to reduce the need for construction work on the site, thereby reducing the causes of industrial accidents.

With reference to Figure 2 looks at an embodiment of the present invention in detail.

The intermediate branch line 400 to which the present invention is applied is provided between the upper branch line 300 connected to the upper portion of the electric pole 200 and the branch line fixing rod 500 for forming a branch line, and a pair facing each other. Consists of the upper and lower body, the inner surface of the lower body 110, the groove of the X-shaped plane is formed so that the two rows of mounting grooves (111a, 111b) on which the steel wire (W2) is seated to cross in the center, On the inner surface of the body 120, two rows of protrusions 121a and 121b are formed in corresponding shapes along the seating grooves 111a and 111b, and wires are formed in the seating grooves 111a and 111b of the lower body 110. W2) includes a fastening means 140 for pressing and binding the wire (W2) seated in the seating grooves (111a, 111b) by the protrusions (121a, 121b) of the upper body 120 in a state seated so as to cross. It is characterized by.

In the seating recesses 111a and 111b and the protrusions 121a and 121b, the stranding seating recesses 112 and 122, in which several strands of the strands can be reliably located, are formed to be twisted along the length direction. .

In addition, one of the two rows of seating grooves (111a, 111b) is formed deeper and the other one is formed shallower, one of the two rows of protrusions (121a, 121b) corresponding to the lower formed and the other is formed high It is further provided.

In addition, the present invention is the through-hole 131 is formed in the upper body 120 and the groove (screw hole 130) is formed in the lower body 110 to a predetermined depth is formed through the bolt 141, the upper body ( 120 and the lower body 110 to be fixedly coupled.

By using the wire grippers (100A, 100B) of the present invention will be described a process of fixing the wire (W2) and branch line construction.

The upper branch line 300 used in the present invention as shown in FIG. 3 is assembled in a factory and modularized in advance. In the conventional method, which is generally used, the steel wire (W1) is cut to an appropriate length as necessary in the field, then bent and wound around the connection ring 310 and the insulator 330 to finish the sleeve (or element wire). There is a problem in that the construction of the field is complicated because of the audit. Therefore, the present invention standardizes the upper branch line 300 to produce a modular product in the factory and to exclude the processing process in the field. Since distribution poles are standardized, the upper branch line 300 standardized by the length of the pole is manufactured and supplied by the factory, and in the field construction, the branch line construction can be optimized and constructed by adjusting the length of the middle branch line 400. do.

In the state where the wire gripper 100A according to the present invention is disassembled, one end of the wire W2 is bent by 180 degrees on the insulator 330 connected to the upper branch line 300, and the wire W2 is bent to cross the portion where the wire W2 is bent. The wire gripper (100A) formed by the letter 'X' is seated in the seating grooves (111a, 111b) of the lower body 110 and then coupled to the upper body 120 to face the lower body 110, the protrusions (121a, The upper branch line 300 and the middle branch line 400 may be firmly coupled by pressing and fixing the wires W2 seated on the seating grooves 111a and 111b. In the same manner, in the state in which the wire gripper 100B is disassembled, the wire W2 is bent 180 degrees by hanging on the connecting ring 510 of the branch rod 500, and the wire W2 crosses the bent portion, After seating in the seating grooves 111a and 111b of the lower body 110 formed by X ', the upper body 120 is coupled to face the lower body 110 so that the protrusions 121a and 121b are seated in the seating grooves 111a and 111b. The upper branch line 300 and the middle branch line 400 may be firmly coupled by a method of fixedly coupling through the fastening means 140 while pressing the wire W2 seated on the 111b).

When the fastening means 140 is described in detail, the lower body 110 has a screw hole 130 formed at a predetermined depth from an inner surface to an outer surface, and a through hole 131 is provided at the upper body 120 to provide a bolt ( 141 through the through hole 131 of the upper body 120 is coupled to the upper and lower body 120, 110 by a method of fastening to the screw hole 130 of the lower body 110 to complete the connection work.

In the above branch line construction, the upper branch line 300 and the lower branch line rod 500 use standardized products, and in the field, only the wire W2 used for the middle branch line 400 is cut and used to improve constructability. Can be.
