Description

TECHNICAL FIELD The present invention relates to a workbench used for connecting overhead lines.

[Conventional technology and its problems]

In the overhead line work, the messenger wire is first stretched between the utility poles, then the overhead wire is attached to the messenger wire, and the two left and right overhead lines are connected to the utility pole. It is done by connecting at the position.

To connect the above-mentioned overhead wire ends, an operator gets into the work box attached to the tip of the crane of the pole car, pulls the above-mentioned two overhead wires into this box, and They are connected to each other by a connector or the like, and this connection part is housed in a connection box fixed to a messenger wire.

By the way, in the above connecting work, since the overhead wire is drawn into the box for connection, an extra length of the overhead wire needs to be drawn into the box, and the extra length portion is stored in the connection box. Therefore, the connection box becomes large, and further, since the connection jig and the workbench are placed in the box, the inside of the box becomes narrow and the workability is deteriorated.

[Means for solving the problem]

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and an object of the present invention is to provide an overhead wire connection workbench which requires only a short extra wire length for connection and is excellent in connection workability.

That is, the present invention relates to an overhead wire connecting work table 1 that is used by suspending it on a messenger wire 11, which comprises a plurality of pairs of frames 2 for suspending on the messenger wire 11, and a connection suspended on the messenger wire 11. Fastening rods 3 provided at the bottom of the pair of frames 2 for pressing and fixing the bottom plate 17 of the box 10 with the inner walls of the pair of frames 2, and a connection attached to one side of the side of the pair of frames 2. A fixed base 4 for fixing the jig 9, and the fixed base 4 attached to the opposite side of the fixed base 4 with the counter frame 2 interposed therebetween.
Is a work balancer 1 for connecting overhead cables, which comprises a balancer 5 for horizontally holding

Further, in the workbench of the present invention, when the connection jig is fixed, the weight of the fixed stand causes the fixed stand 4 to be tilted. Therefore, the position of the balancer 5 can be screw-rotated to move the fixed stand 4 horizontally.

[Action]

Since the connection box is fixed to the workbench and the workbench is suspended from the messenger wire to perform the connection work, the extra length of the wire at the time of connection can be short and the connection box can be downsized. Further, since the connection jig is fixed to the work table adjacent to the connection box, the work space in the pole car box can be wide, and the fixing table is horizontally held by the balancer, so that the connection work can be efficiently performed. .

Also, the work table of the present invention is a portable work table, and a connection work is performed by holding a grip portion provided on an upper portion of a pair frame of the work table with, for example, a messenger wire, and removing the work table after the work is completed. Is something that can be done.

〔Example〕

Hereinafter, the configuration of the work table of the present invention will be specifically described with reference to FIG.

FIG. 1 is a partially cutaway perspective view showing an embodiment of a workbench of the present invention. In the figure, 1 is a workbench, 2 is a frame,
3 is a fastening rod, 4 is a fixed base, and 5 is a balancer.

The workbench 1 includes two pairs of frames 2 with grips 6 for suspending the workbench 1 on a messenger wire or the like, and a bottom plate 17 of a connection box provided at the lower portion of the frame 2 on an inner wall of each of the frames 2. Two fastening rods 3 for pressing and fixing with, a fixing base 4 for attaching a connecting jig attached to one side of the frame 2, the fixing base attached to the other side of the frame 2. And a balancer 5 for maintaining the horizontal position of the balance 4. Further, the fixing base 4 is provided with a positioning hole 7 for inserting a fixing screw.

Next, the method of performing the connection work using the work table of the present invention, the second,
This will be specifically described with reference to FIG.

FIG. 2 is an explanatory view of a method of connecting the optical fiber cable by suspending the workbench of the present invention shown in FIG. 1 above on a messenger wire. In the figure, 9 is a connection jig, 10 is a connection box with the cover removed, and 11 is a messenger wire.

A connecting jig 9 for connecting the wires to each other is previously attached to the fixed table 4 of the work table 1, and the balancer 5 is set at a predetermined position so that the fixed table 4 is held horizontally.
Is lifted from below the junction box 10 attached to the messenger wire 11, and the grip portion 6 of the workbench 1 is screwed onto the messenger wire 11 to be grasped, and then the fastening rod 3 is tightened with the thumbscrew 16 to connect the junction box 10. The bottom plate 17 is fixed by being sandwiched between the frames 2.

Then, the operator reached out from the inside of the box of the pole car and connected the ends of the optical fibers of the two optical fiber cables 15 with the connection jig 9.

The fixing base 4 is provided with a positioning hole 7 for the connecting jig 9, and a fixing screw 8 is inserted into this hole 7 and the fixing screw 8 is inserted into a screw hole 18 provided at the bottom of the connecting jig 9. The connecting jig 9 was fixed to the fixed base 4 by screwing.

FIG. 3 is a side view of the junction box 10 shown in FIG. In the figure, 12 is a connector. The connection box 10 is fixed to the messenger wire 11, and each optical fiber 13 of the two optical fiber cables 15 from the left and right is the above connection box.
It is connected by a connector 12 introduced at 10.

The connector 12 and the optical fiber extra length portion 14 are housed in the connection box 10.

Then, remove the worktable 1 from the messenger wire 11,
The connection work was completed by attaching a cover (not shown) to the connection box 10.

Although the connection of the optical fiber cable has been described in the present embodiment, the workbench of the present invention can be applied to the connection of an arbitrary overhead line such as an overhead power transmission line or a communication line.

〔effect〕

According to the overhead wire connection work table of the present invention, the extra wire length required to connect the overhead wire is short, and the connection box can be downsized, and further, it can be widely used in the box of a pole car to perform connection work. Various advantages, such as efficiency, can be obtained.
