Abstract
In a conventional method for extracting a cable, a power cable is reeled in by rotating a reel drum using a drive motor, and therefore there are cases where a power cable in a conduit cannot be extracted with the driving force of the drive motor when a large extraction force is required to extract the power cable from the conduit. The present invention is capable of directly transmitting, to a cable drum (5), a rotational force of rubber tires (9) whose outer circumferential portions are made of elastic rubber, by rotating the rubber tires (9) while bringing the rubber tires (9) into intimate contact with outer faces of the cable drum (5), and is capable of reliably rotating the cable drum (5).
Claims4
A cable reeling device that is to be mounted in a vehicle for reeling in a power cable laid in an underground conduit, the device comprising:
- a turn table that is provided on a carrier and is capable of rotating;
- two arms that are provided in parallel on the turn table and each of which is capable of rotating in a vertical direction around a rotation center that is substantially a connection point between the arm and the turn table;
- drum support members that are attached to the respective arms and to which a cable drum disposed between the two arms is locked;
- and
- a drum rotating device for rotating the cable drum locked to the drum support members,
- wherein the drum rotating device comprising:
- rubber tires with outer circumferential portions having a circular shape thereof being made of elastic rubber, for rotating the cable drum by rotating with the outer circumferential portions being in intimate contact with outer faces of the cable drum locked to the drum support members;
- a rubber tire fixing shaft that is connected to at least two of the rubber tires and rotates around a rotation axis that is a center axis in a longitudinal direction thereof and
- a rubber tire rotation driving means for rotating the rubber tire fixing shaft.
