Similarly, the right rotary actuator 32 is also flanged to a second support plate member 35 disposed at an intermediate position of the pipe column 14 with the output shaft 33 facing upward.
The rotary actuator 31 (the same applies to the rotary actuator 32) is flange-attached to the first support plate member 34, and the portion excluding the output shaft 33 is housed in the pipe column 13 in a sealed state.

A cylindrical first connecting shaft member 36 is mounted on the output shaft 33 of the left rotary actuator 31 so that the shaft centers thereof are aligned, and a cylindrical first connecting shaft member 36 is attached to the upper end portion of the connecting shaft member 36. A bearing member 37 is connected with its axis aligned. Similarly, the second rotary shaft 32 on the right side is mounted with a cylindrical second connecting shaft member 38 with its axial center aligned, and a cylindrical second bearing member 39 is attached to the upper end of the connecting shaft member 38. The axes are connected together.
Since the rotary actuators 31 and 32 described above can limit the rotational movement angle of each output shaft 33, the connecting shaft member 36 and the bearing member 37 can rotate within the pipe column 13 by driving the left rotary actuator 31. The connecting shaft member 38 and the bearing member 39 can be rotated in the pipe column 14 by driving the right rotary actuator 32.

Then, the base portion of the first arm 40 arranged horizontally is fixed to the left bearing member 37, and the base portion of the second arm 41 arranged horizontally is fixed to the right bearing member 39. Thus, by rotating the rotary actuators 31 and 32 synchronously, the left and right arms 40 and 41 arranged opposite to each other can be opened / closed around the base, and the angle or biasing direction can be adjusted.
A first bearing 42 whose vertical center is the axis is attached to the tip of the left arm 40, and a first rotating shaft 43 is rotatably provided via the bearing 42, and the right arm A second bearing 44 whose axis is in the vertical direction is also attached to the front portion of 41, and a second rotating shaft 45 is rotatably provided through this bearing 44.

Thus, the tires 47 and 48 are arranged to face each other with the arms 40 and 41 between the pipe columns 13 and 14.
Here, a rubber hollow tire having a drum shape with a bulging center is used as the tire, but the present invention is not limited to this. For example, depending on the rubber material, a solid tire may be used. It can also be used, and tires of other materials can also be used.

First and second hydraulic motors (examples of first and second rotational power sources) 49 and 50 are arranged in the pipe pillars 13 and 14, respectively. An electric motor or the like can be used instead of the hydraulic motor.
The left hydraulic motor 49 is flange-attached to a third support plate 52 arranged at an upper position of the pipe column 13 with the output shaft 51 directed downward and the axis aligned with the axis of the pipe column 13. Has been. Similarly, the right hydraulic motor 50 is flange-attached to a fourth support plate member 53 disposed at the upper position of the pipe column 14 with the output shaft 51 facing downward.
Since the hydraulic motor 49 (same for the hydraulic motor 50) is flanged to the third support plate member 52, the portion excluding the output shaft 51 is housed in the pipe column 13 in a sealed state.

A first intermediate shaft 54 is attached to the output shaft 51 of the left hydraulic motor 49 so that its axes are aligned, and a second intermediate shaft 55 is also attached to the output shaft 51 of the right hydraulic motor 50. It is installed with its axis aligned. The front sides of the intermediate shafts 54 and 55 are freely mounted in bearing members 37 and 39, which are bearings, with their rotation centers aligned with the rotation centers of the output shafts 33 of the rotary actuators 31 and 32, respectively. It has been.
An oil seal 56 is attached to the inner peripheral portion of each bearing member 37, 39 to prevent oil from flowing out between the bearing member 37 and the intermediate shaft 54 and between the bearing member 39 and the intermediate shaft 55. It is out.
Thereby, the left hydraulic motor 49 and the rotary actuator 31 and the right hydraulic motor 50 and the rotary actuator 32 can be arranged on the same axis, respectively, and the hydraulic motors 49 and 50 and the rotary actuators 31 and 32 can be arranged. Can be driven individually.

They are connected by a chain (an example of a second endless power transmission member) 62. As a result, the driving force of the hydraulic motors 49 and 50 can be transmitted to the tires 47 and 48 via the chains 61 and 62, respectively. Here, the sprocket 57, sprocket 59, and chain 61 arranged on the left side are covered with a cover (not shown), and the sprocket 58, sprocket 60, and chain 62 arranged on the right side are also covered (not shown). It is covered with water to prevent water from splashing from the outside. Each cover covers the bearing member 37, the arm 40, and the bearing 42, and the bearing member 39, the arm 41, and the bearing 44, but may not be covered.
In addition, if it is the structure which can each transmit the driving force of each hydraulic motor to a tire, a gear and a pulley can be used instead of a sprocket, and a belt can also be used instead of a chain, for example.

The left and right arms 40 and 41 are provided above the middle of the pipe columns 13 and 14 (a height position that is ½ the height of the pipe columns 13 and 14). Immediately below the left and right tires 47, 48, there is provided a water storage part 64 with a drain outlet 63 for accumulating water entering through the rope 12. In addition, it is preferable to comprise the water storage part 64 with stainless steel, and this can improve corrosion resistance, for example, can prevent the pool water containing a rust from flowing out outside. Moreover, since the water storage part 64 inclines toward the drain extraction 63 provided in the center lower part, the water in the water storage part 64 can be drained outside via the drain extraction 63. Further, by setting the distance between the lower end position of each of the long holes 18 and 19 and the bottom surface of the water storage portion 64 to be, for example, 10 to 20 mm, the water in the water storage portion 64 is supplied to each length without operating the drain removal 63. It can also be discharged to the outside through the holes 18 and 19.
Reference numerals 65 and 66 shown in FIGS. 1 and 2 are external connection ports of the rotary actuators 31 and 32 and the hydraulic motors 49 and 50, and reference numeral 67 is an inspection port inside the rope guide device 10.

With this configuration, as shown in FIG. 6A, the left and right tires 47 and 48 are rotationally driven by the hydraulic motors 49 and 50 so that the sandwiched rope 12 is sent out from the rear to the front. Can do. Specifically, in FIG. 6A, the left tire 47 is rotated clockwise (clockwise) and the right tire 48 is rotated counterclockwise (counterclockwise).
As a result, the left and right tires 47 and 48 are rotated by the rotation of the hydraulic motors 49 and 50 so that the angle between the left and right arms 40 and 41 is about 90 degrees as shown in FIGS. 6 (A) to 6 (B). Approaches 180 degrees. Then, as shown in FIG. 6B, the left and right tires 47 and 48 come into contact with the rope 12, and the rope 12 is fed out.
FIG. 6C shows a state where the rope 12 is not provided and the angle between the left and right arms 40 and 41 is 180 degrees.

Then, operation | movement of the rope guide apparatus 10 which concerns on the 1st Embodiment of this invention is demonstrated.
First, in the “standby” (non-operating) state, the hydraulic motors 49 and 50 are stopped, the left and right tires 47 and 48 are not rotated, and the rotary actuators 31 and 32 are not operated. Between the tires 47 and 48 is in an open state (see FIG. 6A).
Next, the state shown in FIG. 6A is a “rope through” state, in which the hydraulic motors 49 and 50 are stopped to cause the left and right tires 47 and 48 to be non-rotating, and the rotary actuators 31 and Since 32 is not operated, the state where the left and right tires 47 and 48 are opened is maintained.

FIG. 6B shows a state in which the rope 12 is fed from a winch drum (not shown) using the rope guide device 10, and the hydraulic motors 49, 50 are fed so that the clamped rope 12 is fed forward from the rear. Is driven to rotate the left and right tires 47, 48. At this time, the left and right arms 40 and 41 move to the inside (between) the pipe columns 13 and 14 by the driving reaction force of the hydraulic motors 49 and 50 so that the left and right tires 47 and 48 fasten the rope 12 from both sides. become. In this way, after the left and right tires 47, 48 come into contact with the rope 12, the tightening force of the rope 12 is increased by the rotational reaction force of the left and right tires 47, 48, and the rope 12 is attached to the left and right tires 47. , 48 can be sent out.
As a result, it is not necessary to sandwich the left and right tires with a cylinder or the like as in the prior art, and the apparatus configuration can be simplified.

If the holding force of the rope 12 by the left and right tires 47 and 48 is weak depending on the size and type of the rope 12, the rotary actuators 31 and 32 are operated to adjust the angles or urging directions of the arms 40 and 41. You can also
With the above method, the work of drawing out the rope 12 can be carried out smoothly.
When the rope 12 is wound by the winch drum, the hydraulic motors 49 and 50 are stopped, the left and right tires 47 and 48 are not rotated, and the left and right tires 47 and 48 are opened (see FIG. 6 (A)). As a result, the rope 12 can freely pass through the rope passage 20.

After the rope 12 is recovered by the above-described method, seawater is discharged into the rope guide device 10 to perform cleaning and cleaning work. However, the device configuration is simple, and the oil outflow is suppressed and further prevented. Therefore, it is possible to reduce the risk of grease leaking out and adhering to the rope during cleaning.
When the rope guide device 10 is maintained, the inspection cover 24 of the rear cover member 16 is removed from the wall member 23 and the rotary actuators 31 and 32 are operated so that the angles formed by the arms 40 and 41 approach 90 degrees. Thus, the tires 47 and 48 can be retracted to the rear of the rope guide device 10. As a result, the tires 47 and 48 can be easily inspected and cleaned, and the inside of the rope guide device 10 can be easily cleaned.
