Shaftless Cable Winding Device {AXISLESS CABLE REEL}

The present invention relates to a cable 41 winding device used for irradiating ground through a borehole, and the like, wherein a rotating shaft is installed at the center of a drum in which the cable 41 is wound and wound outside of the cable 41 and the winding device. In order to connect the power source and various devices, the cable reel 59, which requires a rotary terminal, is essentially required to remove the central rotary shaft of the winding part 30 of the cable 41 and is wound. The mounting portion 30 is formed in a hollow structure so as to incorporate a driving portion 40 such as a power supply and a data logger, and a disk body supported by the support rollers 14 at both ends of the winding portion 30.

When a long distance cable 41 is required for various field tests and remote sensing performed through wire communication and current supply, a cable reel 59 in which a cable 41 is wound in a cylindrical drum having a rotating shaft coupled to a center is provided. Used.

FIG. 1 illustrates a ground survey situation through a borehole, and as shown, a sensor 45 inserted into a borehole and a driver 40 for supplying power to the sensor 45 or receiving a signal from the sensor 45. ) Is connected via a cable 41 wound on a cable reel (59).

As shown in FIG. 1, when the in-hole sensor 45 is inserted, the cable 41 is unwound by rotating the drum on which the cable 41 is wound around the axis of rotation of the center of the cable reel 59. At the time of withdrawal, the cable 41 is wound up by rotating the drum against the axis of rotation.

The conventional cable reel (59) is a structure in which the cable 41 is wound around a drum rotating around a rotating shaft, and the input and output terminals for connecting the wound cable 41 and an external device are generally exposed to the outside. to be.

That is, as shown in FIG. 1, detection or transmission equipment such as a sensor 45 is connected to the end of the cable 41 wound on the cable reel 59, an input / output terminal of the cable reel 59, a battery, a receiver, and the like. As the drive unit 40 such as a data logger is connected, a large number of equipments are complicatedly arranged in the field, and excessive space is required, and a long time is also required for transportation, arrangement, and connection of equipment.

In particular, while the input and output terminals connected to the drive unit 40, which is an external device, must maintain a stop state between operations, while the cable 41 wound on the cable reel 59 is continuously rotated to maintain an electrical connection state. In order to the cable reel (59), a rotary terminal (rotary 필수적 子) is essentially required.

The rotary terminal is a terminal which always maintains a contact even when the terminal of either side rotates. In the case of the cable reel 59, the rotary terminal is normally installed around the rotating shaft, but the electrical connection state of the rotating body can be maintained through the rotary terminal. Due to the influence of the minute undulation and induction current, there is a problem that unnecessary changes occur in the current passing through the rotary terminal or is interrupted momentarily.

The current change due to the rotary terminal may cause distortion or noise of the signal when performing communication through the cable 41, and serious malfunction when performing various precision tests and remote detections requiring precise detection. To misleading.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has a winding device in which a cable 41 is wound and unwound as the winding part 30 is rotated, respectively, at a central portion thereof. The front plate 11 and the rear plate 12 having the opening 13 cut out are connected and fixed to be spaced apart from each other. 21 and the rear turntable 22 are installed, respectively, the outer front plate 11 of the front turntable 21 so that a plurality of support rollers 14 in contact with the outer circumferential surface of the front turntable 21 are rotatable.
