Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a guiding device for positioning a leisure craft in a predetermined width direction in a floating state when the leisure craft is mounted on a cradle and stored above the water surface.

``Conventional technology'' Traditionally, recreational boats were stored and managed by floating on the surface of the water, but the boats were damaged due to contact with each other due to vibrations caused by waves, etc., or due to dirt due to adhesion of seaweed, shells, etc. Land-based storage management has recently become mainstream due to the decline in the quality of storage, or due to the trend of the times and the deterioration of important aspects.

This land storage management device is disclosed in Japanese Utility Model Application Publication No. 175557 or Showa 63-3762. A building with a storage floor of It is to be stored and managed by In addition, the latter Japanese Utility Model Publication No. 633762 targets recreational craft having protrusions such as masts, and comprises a multi-stage storage tank, which is collected by a lifting device in the same manner as above and used for recreational craft. The vessels are loaded and stored at intervals, and leisure craft, which are stored in upper tanks, are mounted in the intervals and managed for storage. In addition to the above, there is a device in which a leisure craft is mounted on a slanted salvage platform attached to a salvage truck that reaches an appropriate depth underwater from land, and is salvaged onto land using a winch or the like.

As mentioned above, there are various methods and devices for retrieving recreational craft, but the recreational craft must be positioned in a predetermined position before using the retrieving method or device. However, the reality is that there is currently no guidance device for positioning a leisure boat at a predetermined position.

[Problems to be Solved by the Invention] In the various above-mentioned land storage management devices, it has been a problem to position the leisure boat at a predetermined position on the leisure boat mount. In other words, leisure boats generally have all the cross-sectional shapes in the length direction, including a rectangular stationary structure, a bilge keel, protrusions such as propulsion jet nozzles, and, in the case of yachts, a centerboard elevating recess. Because of the openings such as the above, each type of leisure boat cradle has to be specially designed. Taking these items into account, we have created a leisure boat cradle with a shape that matches the predetermined position of the leisure boat. Prepared and secured for loading.

When a leisure boat is retrieved from the water surface and stored on land, the pre-fixed leisure boat mount is lowered to a depth that does not interfere with the navigation of the leisure boat, and the operator or shore storage manager The leisure boat is stopped at the specified stopping position according to the judgment of the person, the leisure boat mount is raised and touched to the bottom of the leisure boat, and after confirming the specified position, if there is no problem, the load is transferred to the leisure boat mount. It is moved above the water surface and stored on land as a temporary loading condition. If there is any deviation when the predetermined position is confirmed, the leisure boat mount is lowered again to determine the position of the leisure boat, and the above procedure is repeated. Conventionally, this process is often repeated due to movement caused by waves, agitation, or movement due to wind, and because the recreational boat mount is installed below the water surface, it is difficult to visually confirm the specified position. Nowadays, as the population increases, lost time due to this repetitive work has become a problem. Particularly near sunset when the onshore storage facility closes, all these recreational boats return to port all at once, making unloading and unloading work at the marina extremely complicated, and people are waiting for their turn to be stored onshore.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention aims to develop a device for shortening the time required for positioning a leisure craft.

[Means for Solving Problem 1] A guidance device for lifting and retrieving a leisure boat according to the present invention moves up and down in accordance with changes in the tide level inside each erected guidance guide provided on the side of an opposing quay or pier. The floating body includes a roller retraction air cylinder on the opposite side of the floating body, a rack that is attached to the roller retraction air cylinder and moves substantially horizontally in the length direction of the leisure craft, and a slide that guides the movement of the rack. A guide is installed, and a pinion gear that fits into the rack and rotates, a pinion shaft that supports the rotation of this pinion gear, a bearing that supports both ends of this pinion shaft, and a guide that is attached to the opposite side of the floating body, and A roller lever that is fitted onto the pinion shaft and rotates horizontally, a rubber roller that is located at the tip of this roller lever and rotates in contact with the leisure boat, and a torsion bar that is inserted through the pinion shaft. A spring is provided, one end of which is attached to the floating body, and the other end of which is attached to the roller lever, and the leisure boat that enters the port is guided to a predetermined landing place.

[Function] The guidance device for lifting and retrieving a leisure craft according to the present invention engages the side of a leisure craft floating on the water surface with a pinion shaft attached to the side of a floating body located relative to the side of a quay or pier. The leisure craft is guided by a rubber roller at the tip of a roller lever that rotates horizontally, and is fixed in a predetermined position for hoisting and retrieval.The operation is as follows.

a) Before the leisure boat enters the port, the roller retraction air cylinder is set to an idle state, the roller lever is placed on standby with the roller lever extended in the relative direction, and the lifting and retrieval platform is lowered to an appropriate depth underwater.

b) Rubber rollers attached to the tip of the roller lever are brought into contact with both sides of the leisure boat that has entered the port, and the roller lever is moved forward to the designated lifting and retrieval position, and by rotating the roller lever, one end becomes a floating body and the other end A biasing force is applied to the torsion bar spring attached to the roller lever, and the left and right positions of the leisure boat are fixed at the predetermined lifting and retracting positions.

C) Lower the lifting and retrieval platform to an appropriate depth underwater, raise it and place it in contact with the bottom of the leisure craft, and after confirming that it will not move due to waves, etc., set the air cylinder for retracting the roller in a floating state. A roller lever that rotates horizontally by being fitted into a pinion shaft that supports the rotation of the pinion gear, which rotates when activated and is fitted to a rack that moves while being guided by a slide guide. is rotated while applying a biasing force to the torsion bar spring to a position where there is no problem in raising the lifting and retrieving frame of the leisure boat above the water surface.

d) When the lifting and retrieving stand of the leisure boat has risen above the water surface and the lifting and retrieving stand of the next leisure boat has been lowered to an appropriate depth in the water, the air in the air cylinder for drawing in the rollers is released to make it idle. As a result, the torsion bar spring to which the biasing force is applied automatically returns to the state of item a) in which the roller lever is extended in the relative direction, and the actions from item b) are repeated.

[Example 1] An example of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4.

Inside each of the erected guidance guides 1a and 1b provided on the opposite quay wall 1 or the side of the pier, there is a floating body 2 that moves up and down in accordance with the change in the tide level, and a floating body 2 that is parallel to the above-mentioned opposite side surface of the floating body 2 and is horizontally aligned. A rack 5 which is attached to the entry side of the leisure boat 4 of the roller retraction air cylinder 3 and which moves approximately horizontally in the longitudinal direction of the leisure boat 4; A slide guide 6 for guiding the front and back movement of the rack 5 is attached, a pinion gear 7 that fits into the rack 6 and rotates approximately horizontally, a pinion shaft 8 that supports the rotation of the pinion gear 7, and a pinion shaft 8 that supports the rotation of the pinion gear 7. Bearings 8a and 8b that rotatably support the upper and lower ends of the pinion shaft 8 are attached to opposite sides of the floating body 2, and a roller lever 9 whose base end 9a is fitted to the pinion shaft 8 and rotates approximately horizontally A rubber roller 10 that rotates in contact with the leisure boat 4 is attached to the tip of the roller lever 9, and a torsion bar spring 11 is provided by inserting the pinion shaft 8, and one end 11 is attached.
a to the floating body 2, and the other end 11b to the roller lever 9.
The roller lever 9 is attached to the proximal end 9a of the pier, and with the roller lever 9 jutting out in the direction relative to the opposing quay 1 or the pier, the roller lever 9 is brought into contact with the vicinity of the side 4a of the leisure boat 4 that has entered the port, and the roller lever 9 is moved with forward force. A guiding device which applies a biasing force by rotating is guided at two locations, front and rear of the leisure boat 40, to guide the leisure boat entering the port to a predetermined pick-up location.

With the above configuration, before the leisure boat 4 enters the port,
The roller retraction air cylinder 3 is put into an idle state, and the roller lever 9 is kept in a standby state extending in the relative direction of the A position shown in FIG.
0 is submerged in the water to a suitable depth, and the rubber rollers 10 attached to the tips of the roller levers 9 are brought into contact with both sides 4a of the leisure craft 4 that has entered the port, and the leisure craft 4 is then raised to a predetermined position. Move it forward and release the roller lever 9.
By rotating the torsion bar spring 11 from the A position to the B position shown in FIG. The left and right positions of the charter boat 4 are fixed at predetermined positions. Thereafter, after confirming that the hoisting and retrieval platform 50, which had first been lowered to an appropriate depth underwater, was raised and brought into contact with the bottom 4b of the leisure boat 4, and a load was applied to the extent that it would not move due to waves, etc. Air cylinder 3 for drawing rollers in an idle state
is actuated to rotate the pinion gear 7 that rotates by fitting into the rack 5 that moves while being guided by the slide guide 6, and is fitted to the pinion shaft 8 that supports the rotation of the pinion gear 7. A biasing force is applied to the torsion bar spring 11 to move the roller lever 9, which rotates almost horizontally, to the C position shown in FIG. Rotate while doing so. When the lifting and retrieving stand 50 of the leisure boat 4 has risen above the water surface 51 and the lifting and retrieving stand 50 has been lowered to an appropriate depth in the water 51 in order to lift and retrieve the next leisure boat 4, the roller retraction air cylinder 3 By releasing the air and making it in a floating state, the torsion bar spring 11 with biasing force automatically moves the roller lever 9 to the relative direction of the opposite quay wall 1 or the side of the pier at position A shown in Figure 1. It returns to the extended state and becomes ready to guide the next leisure boat 4 to be retrieved.

[Effects of the Invention] As described above, according to the guidance device for displaying a recreational boat of the present invention, the positioning work for lifting and collecting had to be redone many times, but Since it is a fixed place for unloading and retrieval, it is possible to significantly shorten the time for retrieving and retrieving boats, reduce the number of workers, improve work safety, and centralize control at a management office on land. .
