Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This device is mainly used for laying cables such as power cables and communication cables in subway tracks, pulling out the cables wound around a cable drum placed on the ground and following the stairs. Regarding the guide gutter for carrying in the cable used when carrying it inside.

[0002]

[Prior art]

 Conventionally, when pulling out the cable wound around the cable drum placed on the ground and carrying it along the stairs into the trackbed, hanging a fishing wheel on the handrail of the stairs or putting the roller directly on the floor surface I left it and put the cable on this fishing wheel and roller.

In such a case, the cable often comes off the fishing wheel or roller, and therefore, it was necessary to arrange some workers near the fishing wheel or roller for monitoring the cable.

[0004]

[Problems to be solved by the device]

 However, when the cable is carried in by the above-mentioned conventional method, there is a problem that the labor cost is increased because many workers are required for monitoring. In addition, when the cable is placed on a fishing wheel or roller, it may cause injuries due to a hand or foot injury, which is not preferable from the viewpoint of safety management.

[0007] Furthermore, if the cable is dropped from the fishing wheel or roller, or if the cable is loosened between the fishing wheels or between the rollers, there is a drawback that the cable is rubbed against the edge of the stairs or the ground and is damaged. There is also the drawback that workability is poor because a large amount of tension is required to eliminate this.

[0006] Therefore, the present invention can save labor, prevent damage to the cable, have less risk from the viewpoint of safety management, and can carry out the carrying-in work efficiently. An object of the present invention is to provide a device dedicated to carrying in a cable.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a roller having a length substantially equal to the width of the bottom wall at a predetermined distance to a bottom wall of a gutter member having both ends open. Rotatably mounted in a direction in which the axis of rotation of the gutter corresponds to the width direction of the bottom wall, and a roller having a length substantially equal to the height of the side wall at required intervals on both side walls of the gutter member, A structure in which a rotation shaft of the roller is rotatably mounted in a direction coinciding with a height direction of the side wall, and connecting portions are provided at both ends of the gutter member so that the plurality of gutter members are vertically bendably connected to each other. Alternatively, a structure in which a gutter member curved in an arc shape is connected to a required place is adopted.

[0008]

[Action]

 When the gutter members are placed on the stairs or floors leading to the underground and the connecting parts of the adjacent gutter members are connected, each gutter member is flexibly connected in the vertical direction, and along the slopes of the stairs and the floor surface. A guide gutter for carrying in cables is installed.

When the cable is placed on the gutter member, the cables are sequentially loaded by the rotation of the roller provided on the bottom wall.

When the cable rattles in the gutter member and swings to the left or right, the cables are sequentially carried in by the rotation of the rollers provided on both side walls.

[0011]

【Example】

 As shown in FIG. 1, a cable carrying-in gutter according to the present invention comprises a plurality of gutter members 1 connected to each other, and an arc-shaped curved gutter member 2 connected to a corner portion thereof.

As shown in FIG. 2, each of the gutter members 1 is composed of a gutter having a required length and having an open U-shaped cross section.

A roller 4 having a length substantially equal to the width of the bottom wall 3 is provided on the bottom wall 3 of the gutter member 1 at an interval of 1 m in a direction in which the rotation axis thereof coincides with the width direction of the bottom wall 3. It is installed.

Rollers 6 having a length substantially equal to the height of the side walls 5 are provided on both side walls 5 of the gutter member 1 at intervals of 1 m in a direction in which a rotation axis thereof coincides with a height direction of the side walls 5. , And they are installed facing each other.

Bearings 7 a are provided at both ends of the bottom wall 3 at one end of the gutter member 1, and bearings 7 b are provided at the center of the bottom wall 3 at the other end.

As shown in FIG. 1, when the bearings 7a and 7b of the adjacent gutter members 1 are fitted to each other and a pin (not shown) is inserted, the adjacent gutter members 1 are connected so as to be bendable in the vertical direction. It That is, in this embodiment, the bearings 7a and 7b and the pin form a connecting portion.

As shown in FIG. 3, the cable carrying-in gutter configured as described above is placed on the stairs leading to the underground and on the platform. Since each gutter member 1 is flexibly connected in the vertical direction, even if there are portions having different steps, they can be placed along the slope.

When the cable 12 is pulled out from the cable drum 11 placed on the ground and placed on the first gutter member 1 a and the cable drum 11 is rotated, the rollers provided on the bottom wall 3 of each gutter member 1 are rotated. By the rotation of 4, the cable 12 is guided in the length direction of the bottom wall 3 and carried in.

Even if the cable 12 rattles in the middle and swings to the left or right, it is guided in the longitudinal direction of the side wall 5 and carried in by the rotation of the rollers 6 provided on both side walls 5 of the gutter member 1.

In FIG. 3, the cable 12 pulled out from the cable drum 11 may hit the edge of the first gutter member 1a and be damaged. To prevent this, the protective cover 13 shown in FIGS. 4 and 5 is used. May be attached.

As shown in FIGS. 4 and 5, the fixing ring 14 is attached to the tip of the bellows-shaped protective cover 13, and the screws 15 attached to the both side walls 5 of the gutter member 1 a are attached as shown in FIG. The front end of the protective cover 13 is supported by closing and abutting on the side surface of the fixing ring 14.

Further, in order to prevent this cable carrying-in gutter from sliding down on the stairs, as shown in FIGS. 4 and 5, the lower surface of the end part of the bottom wall 3 of the first gutter member 1a is supported by a support base. It is preferable that the bars 18 are welded to each other, the bars 18 are inserted into the bearings 17 provided at both ends of the support base 16, and both ends of the bars 18 are brought into contact with the wall surfaces on both sides of the stairs as shown in FIG. .

Further, in order to prevent the cable 12 from jumping out of the cable carrying-in gutter, a belt may be attached to the outer periphery of each gutter member 1 if necessary.

[0024]

[Effect of device]

 By using the cable carrying-in gutter configured as described above, the number of workers arranged on the way can be reduced to a necessary minimum, and labor can be saved.

The cable rarely jumps out of the cable carrying-in gutter, and in some cases it may jump out, and if it needs to be placed again, it will not be injured by a hand or foot injury. It is also excellent in terms of safety management.

Since the cables are sequentially carried in by the rotation of the rollers in the gutter member, damage due to wear or the like can be prevented and work efficiency is good.
