Description

[Detailed Description of the Invention] The present invention relates to a joint lead work stand used when joining a lead pipe divided into two at the connection point of a communication cable.

Conventionally, when connecting lead pipes that have been split into two, the two lead pipes that have been fitted to the communication cable in advance are manually brought over the cable connection point, and the cut surfaces are butted together to quickly unite the lead pipes. After soldering in several places and integrating the parts while rotating the lead pipe as needed,
The lead work was done evenly around the entire circumference of the cut surface, and the joint lead work was completed.

However, this method requires a lot of manpower, has poor work efficiency as the heavy lead pipes are brought into a narrow space such as a manhole, and is difficult to hold the lead pipes horizontally and stably, making it difficult to connect the cut surfaces. There was a drawback that it was difficult to perform the alignment reliably.

This invention was made in order to eliminate all of the above-mentioned drawbacks of the conventional method.It is installed at the bottom of the lead pipe where joint lead work is being performed, and the lead pipe divided into two parts is placed horizontally and stably on top of the pipe. To provide a lead-jointing stand for a communication cable, which can easily and reliably perform lead-jointing work while supporting the pipe and butting its cut surfaces, and rotating the lead pipe in this state.

The drawing shows one embodiment of the present invention. In the figure, reference numeral 10 denotes a main body of a lead pipe work which is to be installed at the bottom of a lead pipe divided into two parts, which is to be used for joint lead work. It is longer than the entire length of the lead pipe.

Reference numeral 11 denotes attachments for communication cable receivers, which will be described later, provided at both ends of the main body 10.

This mounting tool 11 includes a mounting bolt 11a passing through the center of the upper and lower surfaces of the main body 10, an engagement tool 11b fixed to the upper end of the mounting bolt 11a, and a mounting bolt 11b screwed into the lower end of the mounting bolt 11a for position adjustment. It consists of a thumbscrew 11C.

The engagement fitting 11b is provided with a fitting hole 11b' for a communication cable receiver 30 that is previously installed in the manhole as shown in FIG.

20 slides in the longitudinal direction of the main body 10.
There are at least four supports for the lead pipes that are straddled across the pipe.

Arm rods 21 are symmetrically provided on both sides of the support body 20 and extend obliquely upward so as to be perpendicular to the longitudinal direction of the main body 10, and support rollers 21 are provided at each tip of the arm rods 21 to support the lead pipe for splicing. 22 is pivotally supported.

Next, a method of using the communication cable trunk lead assembly according to the present invention will be explained with reference to FIG.

First, with the two-part lead pipes 50 a and 50 b fitted in advance on the communication cable 40 drawn to the connection point of the communication cable 40 , the main body 10 of the pierced lead work stand is connected to the connection point of the communication cable 40 . Lead pipe 50a.

50 b, and fit the tip end side of the communication cable receiver 30 into the fitting 71, llb' of the engagement fitting 11 b, and then attach the spliced lead work stand main body 10 to the communication cable receiver 30. Support.

Next, the supports 20 on the main body 10 are appropriately slid to position each support 20 on both sides of the lead pipes 50a and sob in the longitudinal direction.

After that, while moving the main body 10 up and down by appropriately rotating the thumbscrew 11C for position adjustment, the lead pipes 50a, 5
Adjust so that 0b is horizontal on the support roller 22 of the support body 20.

Once the cut surfaces of the lead pipes 50 a and 50 b have been brought together in this manner, the lead pipes 50 a and 50 b are rotated on the support roller 22 and jointed lead work is carried out using the conventional method.

It should be noted that this body joint lead work stand shall be removed by the reverse operation as described above after the body joint lead work is completed.

As explained above, according to the communication cable body joint lead work stand according to the present invention, there is no need to carry out body joint lead work while holding the lead pipe manually, resulting in labor saving, improved workability, and This has the advantage of improving the quality of the parts.
