Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tent for connecting overhead cables on a pole for forming a space where the work can be performed without being affected by weather conditions.

The work involved in connecting overhead cables on utility poles is affected by weather conditions such as rain, wind, and temperature, and the work often has to be stopped during rainy or cold weather, which often causes problems.

Therefore, as a convenient measure, as shown in Fig. 1, the messenger wire 2 for supporting the cable 1 is covered with a sheet 3 such as cloth, and a pole-mounted workbench 5 attached to a telephone pole 4 is used as a scaffold. At present, connection work is being carried out while protecting against wind and other factors. However, there is a risk that the sheet 3 may be blown away by the wind or rain may enter the connecting portion, and there is also a drawback that the sheet gets in the way of the work and degrades work efficiency. Currently, as shown in Fig. 2, a pole tent 7 has been developed that can be attached to a ladder truck 6 for pole work, but this can only be applied to ladder trucks, and ladder trucks are expensive. It could not be used in places where the topography and environment made it impossible to use a ladder truck. On the other hand, it could not be used when the connection work required a floor space of eight or more work platforms of the ladder truck. Recently, even when connecting overhead cables, connection devices and measuring instruments have been used, and the scale of the connection has become larger.In addition, when connecting optical cables, which are expected to be introduced in recent years, the floor space of the work space requires a minimum size of about lm x lm, which cannot be handled by the equipment shown in Fig. 2. In view of the above points, the present invention can be manufactured at low cost, can be easily assembled by attaching it to a telephone pole, and can be used without being restricted by the surrounding environment or location when combined with a conventional pole-top workbench as a scaffold. The present invention provides an overhead cable connection work tent that can be used in combination with a wide scaffold when a wide work space is required, and will be described in detail with reference to the drawings below.

FIG. 3 shows an embodiment of the present invention, in which reference numeral 11 denotes a roof portion, and a plurality of support rods 12 are bent at right angles near the base.
and a fan-shaped roof sheet 13 made of cloth, vinyl, etc. and having waterproof properties attached to each of the plurality of support rods 12, respectively.

Reference numeral 14 denotes an exposed column attachment portion of the roof portion 11, and each support beam 12
A support rod support member 15 that supports the support rod 12 so as to extend in a direction orthogonal to the utility pole 4, and a chain 16 that is wound around the utility pole 4, each having a vertical hole into which the bent portions of the base of the support rod are rotatably inserted. It consists of a tightening adjustment part 17 made of bolts and nuts for adjusting the distance between the two metal fittings attached to the chain 16 and tightening them to the utility pole 4.

Note that the chain 16 may be replaced by a band. 1
Reference numeral 8 denotes a side member made of a waterproof sheet such as cloth or vinyl similar to the roof sheet 13;
It is removably attached by a connecting ring 19 at the green end of the ring.

Instead of a strap, it may be attached with a hook, snap, or Velcro. It is a lower part of the second river, and has a support rod 21 similar to that of the roof part 11, and a floor part 22 made of a sheet or silk-like material of cloth or vinyl attached to this support rod 21. This floor member 22 has the role of preventing objects from falling.
The side member 18 is removably fixed and fixed by a connecting member 23 such as a string or chain.

Further, when the lower green of the floor member 22 and the side member 18 are in contact with each other, they may be fixed by a connecting tool similar to the connecting tool 19 used between the roof portion 11 and the side member 18. Each support beam 21 is similarly supported by a utility pole attachment portion 24 similar to the box pole attachment portion 14 on the roof. Note that the support ridges 12 and lower member 2 of the roof portion 11
In the support rods 21 of 0, spacing fittings may be installed between each support rod, and the support rods 12 may be provided with hanging metal fittings for holding tools necessary for connection and cable connection parts. By increasing the length of the support beams 12 and 21, the fan-shaped width of the sheet 13 and the floor member 22, and the distance between the exposed poles of the utility pole attachment portion 14 on the roof and the utility pole attachment portion 24 on the lower member, a larger connection can be achieved. , it is possible to create sufficient work space necessary for optical cable connections, etc. As a scaffold, a conventional platform or a pole workbench as shown in Figure 1 may be installed side by side, or a pole workbench and a polework workbench as shown in Figure 2 may be used. It may be used in combination with the work platform of the ladder truck, and it can be made sufficiently spacious as a scaffold for work. If the work space is relatively narrow, the spacing between the support rods 12 and 21 may be narrowed, and only one pillar workbench may be used as the scaffold. Such a scaffold may be inserted between the side member 18 and the lower member 20. Further, the cable to be connected may be inserted into the interior from between the roof portion 11 and the side member 18. As described above, the overhead cable connection work tent of the present invention has a simple structure, so it can be manufactured at low cost, and since it is attached to a utility pole, it can be installed on a subordinate pole if a small work space is sufficient. By using one workbench as a scaffold, it can be used in surrounding environments or places where it is difficult to use a pole-mounted work ladder truck, and stable work can be performed.

Furthermore, since the roof extends in a direction perpendicular to the utility pole, it can be installed without being affected by the large number of existing cables. It is also easy to install and remove from utility poles. On the other hand, it can be separated into various parts, and the roof and lower parts can be folded down to make it easier to transport and store. Furthermore, by increasing the size and shape of each part, a sufficiently wide work space necessary for connection work of large connection parts, connection work of optical cables, etc. can be obtained by using a wide scaffold. In this case, by reducing the fan-shaped opening of the roof and lower member to the required size and using it together with as many scaffolds as necessary, it can be used even when only a small work space is required.
