Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for unwinding and winding cables that have a rigid connection part in the middle, such as a telemetry cable that is thrown into the water from the deck of an observation ship and suspended. This invention mainly relates to a winding device for spliced cables.

When performing remote underwater measurement of the required depth below the water surface using a ship, a hanging cable with a measurement sensor tied to the tip is fed out into the water using a winding device installed on the deck soil. However, depending on the type of measuring instrument, the sensor itself may be a long waterproof coated cable, and in such cases, the cable suspended from the ship is , 10 The cable sensor on the feeding side, that is, the outer cable, and the suspension cable on the intake side, that is, the inner cable, are connected in series to form a joint cable, and the connection part is For this reason, it is common to have a rod-shaped rigid part. However, the conventional means of delivering and taking in this type of spliced cable from a ship was to wind the cable onto a single drum either directly or through an I-equipment. Then, like a subordinate, he had many shortcomings.

(a) When winding is performed with the connecting part as it is In this case, the rigid part rises diagonally from the winding drum, so when winding the rigid part, it must be handled manually, causing problems such as getting caught. It is necessary to treat the joints so that they do not occur, and even if they are properly folded, excessive bending loads are applied to the rigid parts, which tends to cause damage to the connecting parts and deterioration due to bending.
In addition, electrical performance tends to deteriorate, resulting in mechanical, mechanical,
This may cause electrical failure. 30(b) If the connecting part is removed and operated each time the cable is wound, the problem described in the previous paragraph will be resolved because the rigid part will be stored separately. In addition, additional equipment is required to temporarily secure the cape when attaching and detaching, and the attachment and detachment operations require manpower.

(c) Danger of manual work The VC work described in the previous two items not only requires extra manpower, but also involves handling rotating drums and cables, which can be very dangerous during the work, especially when the ship is in rough weather. If the eyelids shake, it is extremely dangerous.

(d) Decrease in operability During the processing of the above-mentioned joints, the operation of the winding device must be temporarily interrupted, which reduces the operating rate of the device and leads to a decrease in the efficiency of measurement work. do.

(e) Larger structure The set diameter of the drum is determined by the cable diameter and cable flexibility, but of the two types of cables, outer and inner, the one with the larger diameter and less flexibility should be selected. Since the diameter of the drum is determined according to This will cause problems with mooring operations when entering and exiting port.

The present invention has been made in order to eliminate the above-mentioned drawbacks. Namely, an object of the present invention is to have a compact structure, and to continuously operate a spliced cable without using human hands.
The object of the present invention is to provide a winding device for a spliced cable that can be wound and wound. The present invention will be described below based on an illustrated embodiment.

First, on the floor of deck 1 of the ship, which is used as a cable work area,
A large-diameter, flat-type secondary drum 2 is installed horizontally, and this drum 2&$ is fixedly installed at the upper end of a hollow rotary cylinder 3 that is bearing on the deck 1 and extends below the deck.

Therefore, a gear 3a formed on the outer periphery of the lower end of the rotary cylinder 3
is engaged with the output pinion 5VC of the motor 4, which is energized by the secondary operation, so that the secondary drum 2&$ is rotated in a horizontal plane by the secondary operation drive.

Next, on the upper end plate b of the secondary drum 2, the small-diameter primary drum 1 is vertically mounted and equipped, and the front VC is connected with a cable parallel to the axial direction of the primary drum 1. A traverser 8 for lateral feeding is provided upright.

Furthermore, the right side of the primary drum 7, that is, the front right side in the drawing If
C is equipped with a take-up machine 9 and a double capstan 10 that constitute a part of the transmission mechanism, and the capstan 10
is driven by a motor (not shown) which is installed in the take-up machine 9 and is energized by the primary operation, and the primary drum 7 and the traverser 8 are connected to each other through a constant torque transmission mechanism. By being driven by the motor, the cabstan 101
(They are formed to rotate in a vertical plane in conjunction with each other.

On the other hand, on the hollow axis of rotating cylinder 3! IC is the primary drum 7
A small-diameter rotary cylinder 11 that rotates together with the rotary cylinder 11 is suspended, and a subhole 12 for winding a transmission line (described later) is fixed to the lower end 11C of the rotary cylinder 11. By the way, the joint cable 13 wound around both drums 2 and 7 is formed by a large-diameter rubber-coated outer cable 14 that serves as a cable sensor, and a small-diameter inner cable 15 that serves as a suspension cable. The connecting portion between both cables 14 and 15 forms a rod-shaped rigid portion 16 having a diameter X thicker than that of the outer cable 14. Further, an insertion hole 17a in the string direction having a length and diameter that can accommodate the rigid portion 16 is formed at one location on the winding drum 17 of the secondary drum 2, and at the right end of the insertion hole 17a in the drawing. is equipped with a cable sensor (not shown).

Further, the rear end of this insertion hole 17a communicates with a through hole 6a provided in the end plate 6, and this through hole 6a is provided close to the double capstan 10. Next, the manner in which the cable 13 is wound as shown in the attached figure is the manner in which most of the inner cable 15 is wound around the primary drum 7. Explain the state of.

First, the secondary drum 2 is stopped and fixed at the rotational position shown in the figure, and in that state, the winding side of the inner cable 15 is
The cable 15 is passed through the insertion hole 17a through the through-hole 6a, and then the cable 15 is pulled out from the insertion hole 17a through the through-hole 6a and then folded upward and wound around the capstan 10i1C several times. supported sheep 18f1
C, and then the L-order drum 7 via the traverser 8.
Winding the winding drum 1911C, and finally, the inner cable 15
After the winding end of the drum 7 is tied to one place on the drum 7, the capstan 10, the primary drum 7, and the traverser 8 are rotated in the winding direction by the primary operation drive, resulting in the illustrated embodiment.
Note that the wound end of the inner cable 15 that is tied to the primary drum 7 is electrically connected to the transmission line 20 wound on the spool 12 through the inner space of the rotary cylinder 11 by electrical connection. The detailed structure adopts the structure of a transmission line connection device proposed in Japanese Patent Application Laid-Open No. 52-119247.

Next, the operation of the winding device of the embodiment configured as described above will be described.

When the operator performs a winding command operation in the illustrated state of the device, the primary operation drive starts and the carburetor stans 10, 1
The next drum 7 and the traverser 8 rotate in the winding direction,
As a result, the cable 13 is pulled out and the inner wire 1
5 is wound onto the primary drum 7.

When the rigid part 16 is pulled into the insertion hole 17aVC by this operation and is completely accommodated in the hole 17a, the cable sensor detects the inner end of the rigid part 16 and automatically changes the VCl next operation drive to the second operation. As a result, the capstan 10, drum 7, and traverser 8 stop, and
The motor 4 starts and the secondary drum 2 rotates in the winding direction AflC.

As a result, the outer cable 14 is sequentially wound around the winding drum 17 of the secondary drum 2, and the entire length of the cable 14 is wound onto the secondary drum 2. In addition, during this secondary operation VC&$,
It goes without saying that the primary drum 7 horizontally rotates together with the secondary drum 2 while remaining on top of it.

With the entire length of the cable 13 inserted into the device in this way, the rigid portion 16 can be easily inserted into the insertion hole 17afC.
Since the cable 13 is stored in the cable 13, no unreasonable load stress is applied to any part of the cable 13, and all of the above-mentioned operations are performed automatically, so there is no need for any particular operator's intervention, i.e. One-man control is possible.

Note that when the cable 13 is fed out, it operates in the opposite direction to that described above, and specifically, first, the secondary operation drive is performed and the outer cable 14 is fed out, and then the rigid part 16 is pulled out from the insertion hole 17a. The cable sensor detects the starting point and switches to the primary operation drive, which allows the 1st operation to continue.
Next, the drum 7 rotates in the feeding direction and the inner cable 15
As a result, the cable 13f1$ is continuously paid out.

In this way, according to the configuration of the embodiment, the outer cable 1
4 and the inner cable 15 are wound on separate drums 2 and 7, so the diameter of the winding drum 19 of the primary drum 7 for the small diameter and highly flexible inner cable 15 is set small. Therefore, the entire device can be downsized.

It should be noted that the structure of the embodiment can be widely applied to the above-mentioned winding device for suspension cables for measurement, as well as winding devices for various spliced cables used in construction machinery, etc., and similar effects can be obtained. Chill.

As explained above, the cable winding device according to the present invention includes an inner cable, a rigid part whose one end is connected to the tip of the inner cable, and an outer cable whose base end is connected to the other end of the rigid part. A cable winding device for winding a cable, comprising: a primary drum for winding the inner cable; and the primary drum is provided on a side plate, and the winding drum is provided with a rigid part storage section. a secondary drum for winding the outer cable; a guide mechanism for guiding the inner cable to be wound up through the rigid part storage section of the secondary drum to the primary drum; Only the primary drum is driven with the drive stopped, and then when the rigid part is stored in the rigid part storage part l, the driving of the primary drum is stopped and the secondary drum is started to be driven. At the time of feeding, the secondary drum is driven in the reverse direction with the drive of the primary drum stopped, and after that, when the rigid part is paid out from the rigid part storage part, the reverse driving of the secondary drum is stopped. At the same time, since a drive mechanism is provided to start driving the primary drum in reverse, it is possible to continuously feed out or take in a cable having a rigid part, etc. in the middle, without requiring any manual labor. ,
Furthermore, separation of the drums allows the structure to be made more compact, which has the effect of improving usability, safety, and labor saving of the winding device.
