Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is used for work on telephone poles, especially for connecting telephone cables in rainy weather.

(Conventional technology and problems) Conventionally, in connection work of telephone cables in rainy weather,
A fixed awning was used for the suspension line. However, there are many problems in the design, and about 30% is required for work on rainy days.
Had to reduce the work efficiency of.

In other words, since it was spread out like an umbrella and the supporting legs were fixed to the suspension line of the telephone cable, the center of gravity was high and it had to be supported at an unstable position on the pole until the end of assembly, and if there was a gust of wind, There was also a risk of falling. Further, since the pipe is an assembling type, the assembling work itself is time-consuming, such as crawling hands or other parts coming out during the assembling. Moreover, since the center of gravity is lowered to be as stable as possible, the awning of the awning is lowered, the seat leans on the head, and the storage space for the material tools is narrowed. In addition, the awning was opaque and the interior became dim, which sometimes hindered the cable connection work itself.

(Means for Solving the Problems) Therefore, in the present invention, the conventional method of fixing to the suspension wire is to be fixed by inserting into the pipe fastened to the utility pole, and the assembly on the utility pole is minimized and it is opaque. The sheet is made transparent to solve the problems that have conventionally occurred in the curtain system.

(Embodiment) As an embodiment of the present invention, a fastening means 1 for a utility pole is provided at both upper and lower ends of a pipe material having a predetermined length, and a collar is provided at the upper end periphery.
21 is provided and is joined to a brim 31 provided on the base of the fitting leg 3 described later, and a pin 32 is fitted to fix the angle of the arm 4. The fastening means 1 has one side fixed to the pipe material and the other side abutting against the utility pole. Therefore, the belt or chain tightening material 12 is arranged between both ends of the two rounded fixing plates 11. is there. An auxiliary rope 13 is fixed to the upper fastening means, and one end of the auxiliary rope 13 is hooked on a utility pole bolt to cope with a drop at the time of installation.

The fitting leg 3 made of a small-diameter pipe material is provided with a brim 31 at a predetermined position so as to be fitted to the arm receiving portion 2 having the above-described configuration.
The pin 32 is connected to the upper position of the arm 31 with a rope, and the position is fixed by making it correspond to the hole of the collar 21 of the arm receiving portion 2.
In addition, like the arm receiving part 2, an auxiliary rope 33 for preventing fall
The arm portion 4 is provided by bending the upper portion of the brim 31 from above. Short rail material fixing pieces 41, 41 are fixed to the base end and the tip of the arm portion 4 at right angles, and the corresponding rail material fixing pieces 41, 41 on the one side of the arm portion 4 are substantially U-shaped. The rail material 5 is connected so as to be rotatable upward. The state in which it is rotated upward is the state during transportation and lifting, and the state in which it is rotated to the horizontal position is the state during use. A ridge material 43 is projectively fixed to the upper side of the center position of the arm 42 between the rail material fixing pieces 41, 41 with a U-shaped frame. Also, the arm 42 at the ridge material 43 position has a tape to prevent slipping during transportation. Stick 44. Using the building material 43 as a building, a vinyl roof material is stretched between the rails 5 to provide the roof portion 8.
Further, curtain rails 51 are fixed to the lower surfaces of both rail members 5, and a transparent synthetic resin sheet 6 is hung vertically. Therefore, a small room is formed, which is covered with the substantially U-shaped curtain 61 on both sides of the arm 42. Both ends of the curtain 61 positioned on the left and right with the arm 42 sandwiched therebetween are joined by a surface fastener, and are positioned in the middle of the curtain 61 in the height direction. A window 62 is provided as a path for the suspension line and the cable, and the same fastener can be used to open and close the window. The roofing material 7 drips outside the curtain 61, and rainwater falls outside the curtain 61 and does not enter the inside.

In the invention of the present application having the above-mentioned configuration, in use, first, the arm receiving portion 2 is hung on the electric pole, and the fastening means 1 is wound and fixed on the electric pole. At this time, the auxiliary rope 13 is hung on a scaffolding bolt or the like of an electric pole to prepare for a fall. Next, the arm portion 4 in a state where the rail material 5 is folded is lifted, the fitting leg 3 is fitted to the arm receiving portion, and the pin 32 is attached to both the brims 21,3.
Insert into the hole of 1 to determine the angle, then unfold both rail members 5, 5 horizontally, and extend the roof member 7. The curtain 61 hung from the bottom of both rails 5 and 5 is stretched, and the hook-and-loop fastener at the position where the hanging wire and the cable are sandwiched is aligned, and both wires are passed through the window 62, and work preparation is completed. is there.

(Effect of the Invention) By using the present invention having the above-mentioned configuration, the assembling work on the unstable pillar can be simplified and can be performed in a short time. Therefore, it will lead to the reduction of crash accidents,
Also, by using a transparent curtain, the inside of the awning becomes brighter and it becomes easier to identify the color of the core wire during connection work.
In addition, the structure in which the legs are inserted into the arm receiving portion 2 that supports the utility pole makes it possible to raise the center of gravity of the awning, the overhead space is wide, and the rain-free roof sheet does not touch the head or body, This reduces operator fatigue. Further, since the arm receiving portion 2 and the arm portion 4 are fixed by the pin 32, the awning does not change the angle due to the wind,
Since it is a curtain type, it can be opened and closed immediately, and in summer work, it can be used as a shade using only the roofing material 7, which has many advantages.
