[Industrial application]

 The present invention relates to a lifting platform with a port side fixing device (hereinafter, referred to as a fixing device) for simply and securely fixing the hull of a small boat on the table.

[0002]

[Prior Art]

 The repair, inspection, cleaning, repair, remodeling, inspection, and painting of small boats such as fishing boats and leisure ships are usually carried on the lifting platform. A rail is laid on a concrete slide having an inclination angle of about 8 to 10 degrees, and the slide and the rail extend into the sea. To and fro between the sea and land. To place the boat on the sill, guide the boat to the submerged sill, place the boat on the sill in the sea while fine-tuning the relationship between the boat and the sill, and then Taking advantage of the friction between the board and the keel part of the ship, the ship is lifted to the land along with the platform. The board of the ship supports the weight of the ship on the platform, and the abdomen board plays a role in preventing the ship from falling sideways. Therefore, the abdomen plank is indispensable together with the plank on the lifting platform.

[0003]

[Problems to be solved by the device]

 However, this abdomen must be prepared and set in advance according to the outer shape of the vessel, and the work of maneuvering at sea and placing the vessel on a submerged sill is not possible at sea. Since it is blind work, it requires a great deal of skill and manpower.

[0004] Next, since the part where the abdomen touches the side of the ship and comes into contact with and supports the hull cannot be repaired, inspected, cleaned, repaired, modified, inspected, painted, etc., it remains as a baldness and the next machine There was an inconvenience that the hull had to be slid and placed at the meeting, and that part of the hull had to be added again.

Further, the presence of the abdomen tree interferes with the work on the lift boat, narrowing the work space and reducing the work efficiency. The present invention solves the above-mentioned conventional problems, does not require skill and manpower, does not need to perform additional work again, and has a sufficient working space to improve working efficiency. It is an object of the present invention to provide a lifting platform with a fixing device that can be used.

[0006]

[Means for Solving the Problems]

 According to the present invention, the purpose is (a) a deck with a plank laid at a central position corresponding to the keel of the vessel and parallel to the lifting direction; and (b) both sides of the deck in the lifting direction. One or more stanchions that are erected at the edge of the symmetric position of (c), and (c) a structure with one end attached to the inside of the stanchion so as to face each other, and project horizontally in the structure. The other end is attached with a top plate that holds the fixed board, and the horizontal length of the structure is extended to fix the ship with the fixed board from both sides and to contract it. This can be achieved by a fixing device that releases the ship from a state where both sides are fixed, and a lifting platform with a fixing device.

Next, an object of the present invention is to provide a fixing device, which is a pantograph jack-shaped structure having a link mechanism including four arms attached to a column and four connecting portions. One of the two horizontal connecting parts of the object is attached to the pillar and the other is attached to the top plate for holding the fixed board, and the two connecting parts in the center are both provided with circular holes. One of the circular holes provided inside the frame is a female square screw thread and the other is smooth, and a male square screw thread is cut into the circular holes of both frames. And a spindle is inserted into the circular hole of one of the tops with a square screw thread, and is rotatably and axially locked to the circular hole of the other top. Configured, and one end of the spindle and / or This can be preferably achieved by the lifting boat with a fixing device, which is a fixing device in which handles are fixed to both ends and the horizontal length of the structure expands and contracts by the rotation of the handles.

[0010]

[Action]

 Hereinafter, the present invention will be described in more detail. This invention replaces the conventional siding plank with one or more stanchions on the edges of symmetrical positions on both sides of the hoisting direction in the hoisting direction, and one end of the structure facing each other inside the stanchion. A fixed board is attached to the top plate of the other end of the structure that protrudes in the horizontal direction, and the horizontal length of the structure is extended so that the ship is supported by the fixed board. By devising a fixing device that has the function of releasing the ship from the state where both sides were fixed by fixing from the side of the port and then contracting, we aimed to stabilize the hull laterally on the lifting platform. There are features.

In order to mount a ship on the lifting platform of the present invention, it is easy to guide the ship onto the submersion platform by maneuvering, because the support posts are exposed above the surface even when the platform is submerged. . The fixing device before starting this guiding work is attached to the support column in a contracted state. After the keel of the ship was brought into contact with the board on the sill by fine-tuning the vessel, the handle of the fixing device attached to the support was rotated to extend the arm in the horizontal direction. With both sides of the hull fixed, and the hull resting on the platform, the drive unit pulls the platform along the rails to the ground with a wire.

Since the port side is exposed above the water surface, the mounting work is simple and reliable, and one-man operation is possible. Also, since the outer surface on the port side is a flat surface unlike the boat side, it can be fixed easily and securely. The formation of the board-side fixed surface of the fixed board does not require special consideration. The part on the port side where the fixed board comes into contact with can be subjected to unloaded work such as repair, inspection, cleaning, repair, remodeling, inspection and painting from the ship on the afloat after the undercarriage. However, since the fixing device is mounted high on the upper part of the column, a large working space can be secured on the stool, and the usability of the sill is good in terms of work.

It is preferable that the main body of the boat is made of zinc-plated steel and the fixing device is made of stainless steel and phosphor bronze so that there is no corrosion of seawater, maintenance is easy, and meshing between the members is good. It is preferable to use an H-shaped steel for maintaining the rigidity of the column and to reinforce it with an angle because of its structure. Further, when rigidity is required, it is preferable to use two fixing devices that share a spindle in a continuous manner. Further, it is of course preferable to attach and use a fixing device or two fixed fixing devices to two or more columns.

The fixing device can be attached to the column with an inclination angle from horizontal to vertical. When attaching the fixing device to the column, it is preferable to have a certain inclination angle because it facilitates the handle operation of the spindle.

It is preferable that one or more adjusting boards be detachably attached to the fixed board because the stroke can be increased and the adaptability to the type of ship is increased. For buffering reasons, it is preferable to use wood for the fixed and adjustment planks.

【Example】

 Next, embodiments of the present invention will be described in more detail with reference to the drawings, but the present invention is not limited to these embodiments. In this embodiment, a fixing device having a pantograph jack shape was adopted and implemented, and therefore, a lifting stool attached with the fixing device through a column will be described. FIG. 1 is an explanatory view showing a state in which a hull is fixed to a lifting boat with a fixing device according to the present invention. In the figure, 1 is a platform, 2 is a support, 3 is a fixing device, 4 is a board, 5 is a fixing board of the fixing device 3, 6 is a hull, 7 is a port side of the hull 6, 8 is a rail, 9 is a bed 1 The lifting / launching wheels of 10 are hooks for hooking the lifting / launching wires of the platform 1, and 11 is the reinforcing angle of the supporting column 2.

FIG. 1 is an explanatory view as seen from the bow direction. However, struts are erected at both end edges of the platform 1 in the pulling direction (the direction perpendicular to the paper surface), and the struts 2 corresponding to the port side of the hull are The fixing device 3 is attached to the position. The hull 6 is fixed to the platform 1 by the block 4 and the fixing device 3, and the weight of the hull 6 is directly supported by the block 4. Since the rail 8 extends in the water at an inclination of about 8 to 10 degrees, after the ship is set in the water in a state where the hull 6 shown in FIG. By indexing with a device (not shown), the entire hull will be lifted to land and repair, inspection, cleaning, repair, remodeling, inspection, painting, etc. will be performed. One or more stanchions 2 can be erected depending on the type of hull.

FIG. 2 is a front view of the fixing device 3. In the figure, 21 is an arm, 22 is a pin, 23 is a circular hole at both ends of the arm 21, 24 and 25 are tops, and 26 is a pair of circular holes 23 at the connecting portion of the arm 21 and the arm 21 is a top. A bolt screwed to 24 and 25, 27 a spindle screwed with a male square screw thread, 28 a handle for rotating the spindle 27, 29 a bearing, 30 a thrust stopper and 35 a bottom plate, 36 is a stop plate, 37 is a screw, 38 is a top plate, and 39 is a spacer.

In the fixing device 3, a link mechanism is formed such that the pairs of two solid arms face each other, and the circular holes 23 at both ends of the two solid arms are close to the top plate 38 and the bottom plate 35. It is configured such that the arms are engaged with each other by gears formed at both ends of the two fixed arms so that the arms can be rotated.

At the center of the pair of the two fixed arms of the fixing device 3, the tops 24 and 25 are clamped by the arm 21, and the bolts 26 penetrate the circular holes 23 of the arm 21 and the bolts 26 and 25. It is screwed to 25. The tops 24 and 25 are provided with a circular hole through which the spindle 27 passes. The inner surface of the circular hole of the top 24 is smooth, and a square screw thread of a female is screwed into the circular hole of the top 25. The top 24 is not movable in the axial direction of the spindle 27 because the front and rear of the shaft of the spindle 27 are sandwiched by thrust stoppers 30, but the top is freely rotatable. Therefore, when the handle 28 is rotated, the top 25 is moved along the axis of the spindle 27 accordingly, and the link mechanism formed by the four arms is deformed. At this time, the thrust stopper 30 receives a pressing force due to the rotation of the spindle 27. When the top 24 and the top 25 approach each other, that is, when the horizontal stroke of the fixing device 3 is extended, a pressing force acts on the inner thrust thruster 30, and when the top 24 and the top 25 separate from each other, that is, when contracted, the thrust thruster 30 on the outer side exerts a pressing force. To do. The lateral component force of the hull 6 fixed to the platform 1 by the fixing device 3 acts to contract the horizontal stroke of the fixing device 3, and via the fixing board 5 and the arm 21, finally to the outside. Thrust thrust stopper 30 resists the lateral force and supports this.

3 and 4 are front and side views of the top 25, FIGS. 5 and 6 are front and side views of the top 24, and FIGS. 7 and 8 are front and side views of the bolt 26. 3 to 8, 31 is a circular hole provided in the top 25, 32 and 52 are concave portions to which the tip 72 of the bolt 26 is screwed, and 33 and 53 are end faces of the arm 21 contacting the tops 25 and 24. Surface 51, a circular hole provided in the top 24, 72 a screwing portion of the bolt 26 into the recesses 32, 52 of the tops 24, 25, 71 a shaft portion around which the circular holes at both ends of the arm 21 rotate. The reference numeral 73 indicates a surface where the bolt 26 presses the end surface of the arm 21.

The spindle 27 is inserted into the circular holes 31 and 51 provided in the tops 24 and 25, and the tops approach or separate as the spindle 27 rotates. At this time, the circular hole 23 in the end surface of the arm 21 holding the tops 24 and 25 is pivotally supported by the shaft portion 71 of the bolt 26 to rotate.

FIG. 9 is an explanatory view showing a state in which the fixing device 3 is expanded and the hull 6 is fixed on the port side. The rotation of the spindle 27 causes the tops 25 and 24 to approach each other, and the maximum extension up to about twice the stroke of the arm 21 is shown.

FIG. 10 is an explanatory view showing a contracted state when the fixing device 3 is not used. By the rotation of the spindle 27, the tops 25 and 24 are separated from each other, and the horizontal stroke of the fixing device 3 is minimized.

FIG. 11 is an explanatory view showing a situation in which two fixing devices 3 are continuously connected. The two fixing devices 3 connected in series share the spindle 27 and are placed in series (tandem) on one axis. Handles 28 are attached to the upper and lower ends of the spindle 27. Before launching the platform 1, adjust with the lower handle 28 so that the width of the hull to be secured fits in, and after launch, secure the hull using the upper handle 28. Since the upper handle 28 is located higher than the port side of the hull, the operator can turn the handle in a comfortable posture. By connecting the fixing device 3 to the two solid tandems, it can be applied to a larger ship. Therefore, the thickness of each member was increased to create a structure with high rigidity. This makes it possible to withstand the impact of landing.

FIG. 12 is an explanatory view showing a situation at the time of expanding the two fixing devices 3 which are continuously connected. 2 The fixing devices 3 that are fixedly connected to each other are interlocked while maintaining a similar shape to each other.

FIG. 13 is an explanatory diagram showing a situation when an adjusting board is added to the fixed board 5 in order to increase the stroke of the fixing device 3. In the figure, 131 is a connecting hook, 132 is a connecting pin, 134 is a bolt, and 135 is an adjusting board. The connecting hook 131 is hooked on the pin 132 and fixed with the bolt 134 so that the structure can be freely attached and detached. Adjustment boards were implemented for two types of thickness 100 mm and 300 mm. And these were combined appropriately and used according to the ship width.

When the fixing device 3 is attached to the column 2, the inclination of the stationary platen 5 with respect to the column 2 can be changed by selecting the attachment position. The above description has been made for the one parallel to the stanchion 2, that is, perpendicular to the upper surface of the stool 1, but a quadrangle parallel to the stanchion 2 and parallel to the upper surface of the stool 1 was also implemented. This was effective in preventing the hull from moving back and forth. Also, in order to make the steering wheel easy to operate and to use a large steering wheel, we also implemented the one with a 20 degree inclination with respect to the column 2.

A ship width compatibility test was carried out by using the fixing device 3 that is fixedly connected in two. The results are shown in Table 1.

[0030]

[Table 1]

The pedestal 1 used in this test has a width of 4400 mm, H200 steel is used, the post 2 is 3000 mm in height, H150 steel is used, the reinforcing angle is H100 steel, and the fixing device 3 is attached to the stanchion 2 at the pedestal. It was taken 1540 mm and 2210 mm from the upper surface of 1. Further, three columns 2 are used, and a girder is provided at the height of the top and the mounting position of the fixing device 3. In Table 1, the inside air refers to the distance between the adjustment boards that can be expropriated and mounted on the hull. In addition, the stroke can be adjusted by changing the thickness of the spacer 36.

In this embodiment, a pantograph jack-shaped fixing device was used. However, if there is no hindrance to the adjacent deck even if the cylinder protrudes, the cylinder parts of the long jack, the worm jack, and the screw jack are supported by the strut. It is also possible to achieve the same purpose by mounting the fixed board on the end of the jack rod in a play state.

[0033]

[Effect of the device]

 As described in detail above, according to the lifting device with a fixing device of the present invention, since the port side of the hull is fixed, the hull can be easily and reliably fixed to the lifting device with one person's hand on the water or at sea. can do. Since there is no abdomen, the work space on the deck can be wide, and the work can be performed over the entire surface of the ship. The part on the side of the fixed equipment where the fixed board or adjustment board comes into contact can be additionally processed by afloat after the undercarriage. Therefore, there is no leftover part after work. One in which the fixing device 3 is connected in tandem has increased rigidity, and a larger hull can be fixed. Since there are no protrusions on the outside in the width direction of the sill, it does not hinder the adjacent sill. In addition, excellent effects such as easy stroke adjustment can be obtained.
