Figure 10a is a cross-sectional view of the main part for explaining the structure of the reducer in the feeding wire laying apparatus according to the present invention. As shown in FIG. 10B, when the driving shaft adapter 15 is fastened to the driving shaft 14, the driving shaft adapter 15 is bitten and fixed by a snap ring groove 18 on the driving shaft. The driving shaft adapter 15 is not detached by the rotation of the speed reducer 3.

Therefore, the fixed drive shaft 14 and each rotary tire 17 as described above is connected to the reducer 3 for lowering the rotation ratio while increasing the torque of the motor 4 to receive the driving force. Such a reducer can be used in various forms, but the present invention proposes the use of a worm reducer suitable for a compact and lightweight power transmission structure, wherein the worm reducer performs a deceleration at a ratio of 50: 1.

13 to 16 is a view for explaining the structure of the loss prevention pin of the feeding wire laying apparatus according to the present invention.

Meanwhile, reference numeral 34 denotes a hinge, reference numeral 35 denotes a fixing bracket, and reference numeral 36 denotes an upper limit guide.

That is, in the above configuration, the upper limit guide 36 shown in FIG. 13 is installed at a wire feeding part to prevent the wire to be transferred from being separated from the upper or lower portion of the rotary tire 17. The lower limit guide 37 shown is installed at the wire outlet.

In addition, as shown in Figure 14, the upper limit guide 36 of the feeding portion of the wire has a structure that can be folded to reduce the volume and move conveniently when the installation apparatus, as shown in FIG. The pin 30 has a structure that is penetrated by the ball screw 33 so that the pin 32 does not fall out due to natural vibration while being connected to the upper limit guide bracket 31 by a string 32 or the like so as not to be lost.

Looking at the operating principle of the feeding wire laying device configured as described above are as follows.

First, each reducer 3 is connected to a pair of rotation shafts of the motor 4, and the drive shaft 14 is connected to the reducer 3 to be interlocked. At this time, the drive shaft 14 is assembled with the wheel 16 and the rotary tire 17 is integrally rotated.

When the motor 4 generates the driving force under the control of the controller 7 by this configuration, the reducer connected thereto increases the torque while decelerating the rotational speed and transfers the torque to the drive shaft 14.

Accordingly, the wheel 16 and the rotary tire 17 axially coupled to the pair of drive shafts 14 rotate integrally, wherein the pair of motors 4 rotate in opposite directions to each other. The pair of rotary tires 17 also rotate in opposite directions. Therefore, the cable closely adhered between the pair of rotary tires 17 is transferred.

On the other hand, in the present invention, the motor is required to meet the performance of torque 300Kg, traction speed 12m / min or more is required more than 0.8HP. When using the 220V motor, it is convenient to use the internal power supply of the hull, and when using the 24V motor, the motor weight is reduced and the motor power source can be separated separately. Therefore, the motor power unit is included in the controller box during the feeder controller design step.

In addition, the motor uses a 3600rpm, 300W BLDC motor, and generates a torque of 300Kg by connecting a 25: 1 reducer to reduce the weight of the device.

On the other hand, it is common to use 6: 1 in the 1st row, 26: 1 in the 2nd row, and 156: 1 in the 3rd row.However, if the bevel gear 2nd row reducer is adopted to obtain a reduction ratio of 26: 1, the weight of the reducer Is rather heavy, making it difficult to manufacture with a lightweight, portable structure.

Therefore, in order to maintain the 26: 1 reduction ratio, the reducer should be used in two rows, but the worm gear reducer is used to maintain the reduction ratio of 25: 1. At this time, since the worm gear reducer has the disadvantage of being light and severely worn down, it will be used under the traction force of 300Kg. Plan.

Finally, in order to obtain more than 12m / min cable feed speed, the reduction ratio should be about 156: 1 when the tire diameter is 10 ". Table 1 shows the estimation of cable traction speed by motor and reduction ratio.

The rotary tire 17 is formed on the trishaft adapter 15 so as to have a stacked structure, and the gap may be adjusted by the operation of the gap adjusting means, and the electric wire may flow between the rotary tires 17 to install the electric wire. .

In particular, Figure 18 is a combined state diagram of Figure 17, the wire feeding procedure is the same as the above-described procedure, the connector connector of reference numeral 40 can be connected to the cable installation device of the present invention at regular intervals by a cable Connector connector.

It installs a plurality of wire laying devices at regular intervals and connects the wire laying device using the connector connector 40 to deliver the same power and power to each laying device regardless of the length of the wire to be fed. Can feed the wire with the same torque.

That is, the motor is equipped with a controller to control the driving direction and speed, and an electric fuse or a self-blocking circuit so that overcurrent does not flow to the controller or the control device due to overload of the wheels or shafts or short circuits. In order to start or stop at speed, a variable resistor of up to 10 kΩ is connected to the motor speed controller so that the applied voltage can be changed by the change of the resistance value. When several units are operated at the same time, if the same resistance value is given, the connector can be electrically connected to external equipment so that the motor can rotate at the same speed even at a long distance.
