Description

  The present invention relates to a low pressure retention clamp hanger that connects a low pressure retention clamp and a low pressure retention insulator and retains a low voltage wire to a utility pole, and more particularly, when a hanger is attached for connection, the clamp on the hanger attachment end side is a hanger. TECHNICAL FIELD The present invention relates to a low-pressure retaining clamp hanger that does not fall off.

  In the installation work of the low-voltage electric wire laid on the utility pole, the low-pressure detention clamp that holds the low-voltage electric wire is connected to the low-pressure detention insulator attached to the utility pole by the low-pressure detention clamp hanger, and the low-voltage electric wire is secured to the utility pole. In the normal state where the erection operation is completely completed, the tension of the electric wires is balanced, and the low-pressure tension clamp does not fall off from the low-pressure tension clamp hanger.

  FIG. 2 is a tension correlation diagram showing the tension of the low-voltage wire in the construction work of the low-voltage wire. In FIG. 2, the left and right utility poles 60 are each attached with a low-pressure detention insulator 40, and the low-pressure detention clamps 20 are respectively attached to both ends of the low-voltage electric wire 50. Connected by the hanger 30, the low-voltage electric wire 50 is retained by the utility pole 60. In the normal state where the erection operation is completely completed, the tension of the low-voltage electric wire 50 acts in the directions of arrows 1 and 2, and the low-pressure tension clamp 20 does not fall off from the low-pressure tension clamp hanger 30.

  In FIG. 2, A is the working side, and B is the working end side. The tension of the low-voltage electric wire 50 on the work end side indicated by B acts in the direction of the arrow 1, and the low-voltage electric wire 50 is stably held by the electric pole 60 by the low-pressure tension clamp hanger 30. On the other hand, on the working side indicated by A, a force may be applied to the low voltage electric wire 50 in the direction of the arrow 3, and this force is transmitted as the arrow 4 to the working end side of B, and the low pressure tension clamp 20 is moved to the low pressure tension clamp hanger 30. May fall off. Next, this will be described in detail.

  FIG. 3 is a hanger mounting plan view showing a mounting state of a conventional low pressure tension clamp hanger. In FIG. 3, the conventional low-pressure retaining clamp hanger 30 includes an insulating coating portion 31, hanger flattening surfaces 33 and 35, and retaining portions 32 and 34. Further, the hanger flattening surface 33 on the side of the retaining portion 32 is formed closer to the side of the retaining portion 32 than the hanger flattening surface 35 on the side of the retaining portion 34, and the hanger flattening surfaces 33, 35 are provided. Are flattened in the same direction. The hanger is made of SUS material and can withstand a tension of 1 ton or more.

In FIG. 4, the low-pressure tension clamp 20 includes a low-pressure tension clamp main body 23 and a rotor 25, and both ends of the rotor 25 include hanger insertion slits 27. 3 and 4, when the low-voltage electric wire 50 is gripped by the low-pressure tension clamp body 23 of the low-pressure tension clamp 20, the conventional low-pressure tension clamp hanger 30 is first hung in the groove of the low-pressure tension insulator 40. The hanger flattening surface 35 on the side of the retaining portion 34 is inserted from one hanger insertion slit 27 of the rotor 25 of the low-pressure tension clamp main body 23 and set at the position shown in the figure. Since the diameter of the hanger is larger than the slit width, it does not slip out of the slit.

  Next, by pulling the hanger flattened surface 33 on the retaining part 32 side, the hanger insertion slit 27 of the rotor 25 of the low pressure tension clamp main body 23 is attracted to the hanger flattened surface 33 on the retaining part 32 side. The flat crushing surface 33 is inserted from the other hanger insertion slit 27 that has been drawn, and is set at the position shown in the figure.

  In this way, the low-voltage electric wire 50 is gripped by the low-voltage tension clamp main body 23 and placed by the low-voltage tension clamp hanger 30 at the time of a series of construction to be clamped to the utility pole 60, and a force is applied in the direction of the arrow 3 on the A side in FIG. This force is transmitted to the work end side of B as an arrow 4. At this time, the rotor 25 is pushed back in the direction of the low-pressure detention insulator 40, and the hanger flattening surface 33 comes out of the hanger insertion slit 27, and further pushed back, the hanger flattening surface 35 comes out of the hanger insertion slit 27 and low pressure The retaining clamp 20 falls off from the low-pressure retaining clamp hanger 30, and the low-voltage electric wire 50 droops greatly toward the ground, causing a serious accident.

The purpose of the present invention is to fix the hanger mounting end clamp from the hanger when the hanger is attached to connect the low pressure detent clamp to the low pressure detent insulator. A low-pressure retaining clamp hanger that does not fall off is provided.

  The low-pressure retention clamp hanger of the present invention is a low-pressure retention clamp hanger that connects a low-pressure retention clamp and a low-pressure retention insulator and retains a low-voltage electric wire on a utility pole. A hanger flattened surface between the retaining portion and the insulation covering portion, and the hanger flattened surface of one retaining portion and the hanger flattened surface of the other retaining portion are The hanger flattened surfaces have different distances from the stop portions and are arranged at different positions, and the flattened surfaces of the hanger flattened surfaces are formed to be orthogonal to each other.

  The insulation coating portion of the low-pressure tension clamp hanger of the present invention has a horseshoe shape.

  ADVANTAGE OF THE INVENTION According to this invention, when attaching a hanger for the connection of a low pressure retention clamp and a low pressure retention insulator, the low pressure retention clamp hanger by which the clamp of the hanger attachment completion side does not drop from a hanger can be provided.

The tension correlation diagram which shows the tension of the low voltage electric wire in the construction work of the low voltage electric wire. The hanger attachment top view which shows the attachment state of the conventional low voltage | pressure retention clamp hanger. The hanger attachment front view which shows the attachment state of the conventional low voltage | pressure retention clamp hanger.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a hanger mounting plan view showing a mounting state of the low-pressure detention clamp hanger according to the present invention, and the portions of the low-voltage detention insulator 40 and the low-voltage electric wire 50 in FIG. 3 are omitted. In FIG. 1, the low-pressure tension clamp hanger 10 includes an insulating covering portion 11 having a horseshoe shape, and retaining portions 12 and 14 at both ends of the insulating covering portion 11, and the retaining portions 12 and 14 and the insulating covering portion 11. The hanger flattened surfaces 13 and 15 are respectively provided between the hanger flattened surfaces 13 and 15, and the hanger flattened surface 13 of the one retaining portion and the hanger flattened surface 15 of the other retaining portion are the retaining portions 12 and 14. The hanger flattened surfaces 13 and 15 are disposed at different positions from each other, and the flattened surfaces of the hanger flattened surfaces 13 and 15 are orthogonal to each other.

  3 and 4, when the low-voltage electric wire 50 is gripped by the low-pressure tension clamp body 23 of the low-pressure tension clamp 20, the low-pressure tension clamp hanger 10 is first hung in the groove of the low-pressure tension insulator 40, and then Further, the hanger flattening surface 15 on the side of the retaining portion 14 is inserted from one hanger insertion slit 27 of the rotor 25 of the low-pressure tension clamp main body 23 and set at the position shown in the figure.

  Next, the other hanger insertion slit 27 of the rotor 25 of the low-pressure tension clamp main body 23 is drawn toward the hanger flattening surface 13 on the retaining portion 12 side by pulling the hanger flattening surface 13 on the retaining portion 12 side. . The rotor 25 is rotated to a desired position, the hanger flattened surface 13 and the hanger insertion slit 27 are positioned in the same plane, and then the hanger flattened surface 13 is inserted and set at the position shown in the figure.

  In this case, when a force is applied in the direction of the arrow 3 on the A side in FIG. 2 and transmitted as an arrow 4 to the work end side of B, the rotor 25 is pushed back in the direction of the low-pressure detention lever 40 as in the conventional case. The hanger flattening surface 13 comes out of the hanger insertion slit 27. When pushed back further, the end of the hanger insertion slit 27 comes into contact with the hanger flattened surface 15, but the hanger insert slit 27 and the hanger flattened surface 15 are not in the same plane, so that they come out of the hanger insert slit 27 and are low pressure. The retention clamp 20 falls off from the low-pressure retention clamp hanger 30, and the low-voltage electric wire 50 does not drastically drop toward the ground. Since the hanger is a SUS material that can withstand a tension of 1 ton or more, the horseshoe shape does not extend in a short time and does not come off the groove of the low-pressure retaining insulator 40. During that time, the hanger flattened surface 13 senses the impact vibration that has come out of the hanger insertion slit 27 and immediately performs repair work, thereby preventing a serious accident.

  As described above, according to the present invention, when one hanger flattened surface comes out of the hanger insertion slit, it is possible to prevent a serious accident by detecting the shock vibration that has come out and immediately performing repair work. Therefore, it is possible to provide a low-pressure retaining clamp hanger in which the clamp on the hanger attachment end side does not fall off the hanger.
