In this embodiment, the opening/closing direction of the sliding hatch cover coincides with the horizontal direction and width direction of the ship. The length direction of the rain shelter for shipping coincides with the longitudinal direction and the length direction of the ship, and the width direction of the rain shelter for shipping coincides with the lateral direction and the width direction of the ship.

First, the ship loader and ship will be described. As shown in FIG. 1, a ship loader 1 includes a traveling portion 4 that travels on a rail 3 laid on a quay 2, a turning portion 5 that is rotatably provided on the traveling portion 4, and a rotating portion 5 that can be elevated. A freely provided boom 6 and a nozzle portion 8 suspended from the tip of the boom 6 for supplying cargo such as grain into a hold 7 are provided. The boom 6 is provided with a conveyor (not shown) for transferring cargo from the wharf 2 to the nozzle section 8 . It should be noted that cargo is not limited to grain. The load may also be other bulk items that do not like to get wet in the rain.

As shown in FIG. 1, ship 9 is a cargo ship. A ship 9 includes a hold 7 having an upper opening 10 and a sliding hatch cover 11 for opening and closing the upper opening 10 . A pair of sliding hatch covers 11 are provided on the left and right sides of the ship 9 so as to be slidable in the left and right direction. That is, the sliding hatch cover 11 is of a left and right double-opening type, and the upper opening 10 is closed by abutting the opposite ends 12 and the upper opening 10 is opened by separating the opposite ends 12 from each other. Also, the sliding hatch cover 11 is formed so as to open the upper opening 10 at arbitrary intervals. Hereinafter, an opening between the sliding hatch covers 11 formed by opening the sliding hatch covers 11 will be referred to as a hatch opening 13 . In addition, the sliding hatch cover 11 may be provided so as to be openable and closable in the longitudinal direction of the ship 9 .

Next, a rain protection device for shipping according to this embodiment will be described.

As shown in FIGS. 1 to 3, the shipping rain shelter 20 includes a device body 20A configured to cover the hatch opening 13. As shown in FIGS. The apparatus main body 20A is arranged across the pair of sliding hatch covers 11 when the pair of sliding hatch covers 11 are opened, and covers the hatch opening 13. - 特許庁

The apparatus main body 20A includes a rail 19 arranged on the sliding hatch cover 11, a shipboard chute 22 provided on the rail 19 so as to be free to travel and covering a part of the hatch opening 13, and a lid covering the other part of the hatch opening 13. a member 23;

The rails 19 are arranged on the left and right sliding hatch covers 11 in parallel and extending in the front-rear direction. The rail 19 is configured by connecting a plurality of rail pieces 21 shorter than the longitudinal dimension of the hatch opening 13 in the longitudinal direction (front-rear direction). The length of the rail 19 is set so as to be approximately the same as the front-rear length of the hatch opening 13 when a predetermined number of rail pieces 21 are connected. Note that the rails 19 may not have a connecting structure. In this case, one rail piece 21 constitutes the rail 19 , and the length of the rail piece 21 is preferably set substantially equal to the length of the hatch opening 13 .

As shown in FIG. 2 , the shipboard chute 22 includes a running portion 31 provided on the rail 19 so as to be free to run, and a substantially cylindrical chute body portion 32 into which the nozzle portion 8 is inserted. The traveling part 31 has a plurality of fixed casters. The fixed casters are common to the fixed casters 34 of the lid member 23 shown in FIG.

The nozzle portion 8 of the ship loader 1 is provided with a cover member 14 that covers the chute body portion 32 from above to prevent the cargo from getting wet.

The cover member 23 is formed to be extendable in the front-rear direction, and is arranged in front of and behind the shipboard chute 22 . One end of the lid member 23 in the front-rear direction is fixed to the shipboard chute 22 . The other end of the cover member 23 in the front-rear direction is detachably fixed to the rail 19 near the end of the hatch opening 13 . The cover member 23 expands and contracts according to the travel of the shipboard chute 22 . For example, as shown in FIGS. 5 and 6, when the on-board chute 22 is pushed by the nozzle portion 8 when the cargo B is supplied and the on-board chute 22 travels forward, the cover member 23 ahead of the on-board chute 22 moves forward. It contracts, and the lid member 23 behind the shipboard chute 22 extends forward.

The lid member 23 includes a plurality of bellows portions 69 that are formed to be stretchable in the front-rear direction, and a bellows support portion 70 that supports the bellows portions 69 .

The bellows portion 69 covers a plurality of arch frames 42 formed in an arch shape extending over the left and right rail pieces 21, an elastic link 43 connecting the arch frames 42 to each other so as to be close to each other in the front-rear direction. A waterproof sheet 41 is provided.

As shown in FIG. 7, the telescopic link 43 is configured by connecting a plurality of cross members 52 each having a pair of rod-shaped frames 50 connected via pins 51 in an X shape. The cross members 52 are connected to each other by connecting the ends of the rod-shaped frames 50 via the pins 51 . The ends of the cross member 52 are classified into a fixed end 52a fixed to the arch frame 42 and a movable end 52b slidably provided on the arch frame 42. As shown in FIG. The movable end 52b is rotatably connected to the slider 53 via the pin 51. As shown in FIG. The slider 53 is a tubular member and is slidably fitted to the arch frame 42 .

The waterproof sheet 41 is a flexible sheet, and can be deformed so as to expand and contract between the arch frames 42 .

As shown in FIGS. 2 and 8 , the bellows support portion 70 is provided at the end portion of the bellows portion 69 and formed in an arch shape extending over the pair of hatch covers 11 . The lower end of the bellows support portion 70 is also provided with fixed casters similar to those described above. A rain protection sheet 76 is provided on the bellows support portion 70 .

Further, as shown in FIGS. 2 and 8 , an end sheet 64 is provided on the bellows support portion 70 positioned at the other end of the lid member 23 . Thereby, the hatch opening 13 formed between the side surfaces of the sliding hatch cover 11 can also be closed.

By the way, there is a gap between the device main body 20A and the sliding hatch cover 11, and it is conceivable that rainwater may enter the hatch opening side through this gap. Specifically, the waterproof sheet 41 forming the outer skin of the bellows portion 69 in FIG. 4 deforms into a bellows shape. Therefore, there is a gap between the rail 19 and the waterproof sheet 41, and it is conceivable that rainwater may enter the hatch opening 13 through this gap. In addition, when the sliding hatch cover 11 and the rail 19 shown in FIG. It is conceivable that rainwater may infiltrate into

Therefore, as shown in FIGS. 4 and 9, the rain protection device 20 for shipping includes a water stop portion 100 that suppresses water from entering the hatch opening 13 side (right side) from the gap between the sliding hatch cover 11 and the device main body 20A. Prepare. The water stop part 100 is provided between a first seal 80 and a second seal 81 for suppressing wind and water from entering from between the rail 19 and the sliding hatch cover 11, and between the water stop sheet 41 and the rail 19. A water stop member 88 is provided.

Here, the rail 19 forms a base portion 20B provided on the apparatus main body 20A and placed on the sliding hatch cover 11. As shown in FIG. The base 20B is positioned at the lowest end of the apparatus main body 20A and serves to support the weight of the upper portion of the apparatus main body 20A.

The water stop member 88 is composed of a brush and includes a brush head 89 and brush bristles 90 planted on the brush head 89 . Brush head 89 is supported on rail 19 via bracket 82 . The brush bristles 90 are made of resin, metal, animal hair, or the like. The tips of the brush bristles 90 are brought into contact with the inner surface of the waterproof sheet 41 . The waterproof member 88 is made of a brush and has air permeability. Thereby, the pressure in the hold 7 can be released. The waterproof member 88 may be made of a mesh-like soft resin sheet or the like. By providing a water stop member 88 consisting of a brush or the like in the gap between the rail 19 and the water stop sheet 41, the appropriately deformed brush or the like for the gap that changes due to the expansion and contraction of the water stop sheet 41 prevents entry of wind and water from the outside. can work to prevent

The first seal 80 is made of a relatively soft elastic material such as rubber in the form of a thin sheet with a constant thickness. A base end portion of the first seal 80 is supported by the rail 19 via a bracket 82 , and a tip end portion of the first seal 80 is overlapped with the upper surface of the slide type hatch cover 11 . The bracket 82 is formed to extend continuously in the extending direction (horizontal direction) of the rail 19 and extends to the opposite side of the hatch opening 13, that is, to the side opposite to the hatch opening (left side). A base end portion of the first seal 80 is attached to the inclined attachment surface 82 a of the bracket 82 with a bolt 91 . The middle portion of the first seal 80 is curved to accommodate the angular difference created between the proximal and distal ends. As a result, a force is generated in the intermediate portion in a direction to restore the shape of the first seal 80 , and this force presses the tip portion against the sliding hatch cover 11 . Brush head 89 is bolted to bracket 82 with common bolt 91 along with the proximal end of first seal 80 . As a result, the water stop member 88 and the first seal 80 are continuously connected, and water can be stopped from the sliding hatch cover 11 to the water stop sheet 41 .

The second seal 81 constitutes a seal device referred to in the claims, and is a characteristic part of this embodiment.

First, before describing the second seal 81 of the present embodiment, the second seal of the device of Patent Document 1 (referred to as a comparative example) will be described.

As shown in FIG. 14, in the comparative example, a lip seal 150 having a V-shaped cross section is used as the second seal. The lip seal 150 is made of an elastic material such as rubber, and is detachably attached to the bottom surface of the rail 19 .

Specifically, a metallic seal holder 151 is provided on the bottom surface of the rail 19 and the lip seal 150 is held by this seal holder 151 . The seal holder 151 includes a mounting base 152 integrally attached to the bottom surface of the rail 19, and a pair of legs 154 detachably attached to the bottom surface of the mounting base 152 with bolts 153 and separated from each other. The pair of leg portions 154 hold the lip seal 150 between them and have claws 155 and 156 that engage with the lip seal 150 . A third seal 157 is provided on the bottom surfaces of the pair of legs 154 by adhesion or the like.

However, since the lip seal 150 of the comparative example is composed of a single elastic member, there is still room for improvement in terms of improving sealing performance.

For example, the lip seal 150 is an elastic member having a V-shaped cross section, and seals the gap by opening and closing according to the size of the gap between the leg portion 154 and the hatch cover 11 . However, since the maximum opening is not so large, if the gap becomes large, the gap cannot be completely closed, or the surface pressure on the hatch cover 11 becomes weak. Therefore, when the gap is large, a seal having an appropriate surface pressure and a displacement to close the gap is required.

Therefore, in this embodiment, as shown in FIG. 9, the second seal 81 is configured by a seal device 101 different from the lip seal 150 of the comparative example. The configuration of this embodiment will be described below with reference to FIG. 10 showing an enlarged main part.

FIG. 10A shows the state in which the base 20B is not placed on the hatch cover 11 and the second seal 81 is in a natural state not in contact with the hatch cover 11. FIG. FIG. 10B shows the state when the base 20B is placed on the hatch cover 11 and the second seal 81 is in contact with the hatch cover 11. FIG. In FIG. 10C, although the base 20B is basically placed on the hatch cover 11, the hatch cover 11 is not flat in the longitudinal direction (front-rear direction) of the base 20B. 11, the second seal 81 is in contact with the hatch cover 11. FIG.

As illustrated, the second seal 81 as the sealing device 101 includes an elastic member 102 that contacts the hatch cover 11 and a biasing mechanism 103 that biases the elastic member 102 toward the hatch cover 11 .

A base 104 similar to the seal holder 151 of the comparative example is provided on the bottom surface of the rail 19 . This base 104 also forms the base 20B of the apparatus main body 20A. The base 104 includes a mounting base 105 integrally attached to the bottom surface of the rail 19, and a pair of spaced apart mounting bases 105 that are detachably attached to the left and right ends of the bottom surface of the mounting base 105 with bolts (not shown). and legs 106 of the . However, since the legs 106 are not provided with claws as in the comparative example, the cost required for machining the claws can be reduced. A third seal 107 is provided on the bottom surface of the pair of legs 106 .

The second seal 81 is arranged between the pair of legs 106 and below the mounting base 105 . The elastic member 102 is made of an elastic material such as rubber, has a substantially square cross-sectional shape, and its bottom surface is curved in an arcuate cross-section. The elastic member 102 has a relatively large vertical height H, and is sufficiently tall that rainwater cannot get over it when it contacts the hatch cover 11 as shown in FIGS. 10B and 10C. has a height H. The width (width in the left-right direction) of the elastic member 102 is made smaller than the interval between the pair of leg portions 106 .

The elastic member 102 can be made of a solid elastic material (eg, rubber) having a relatively high hardness in consideration of durability. However, the form of the elastic member 102 is not limited to this. The elastic member 102 may be made of a solid elastic material with relatively low hardness, or a porous elastic material (eg, foam rubber).

Biasing mechanism 103 includes a mechanical spring. As the biasing mechanism 103, a soft rubber having elastic properties like a spring may be used. The biasing mechanism 103 of this embodiment is formed by a coil spring 108 which is a kind of mechanical spring. The coil spring 108 is made of metal and arranged so as to be able to expand and contract in the vertical direction.

The third seal 107 is formed of a sheet of constant thickness made of an elastic material such as solid rubber. The vertical thickness of the third seal 107 is significantly smaller than the height H of the elastic member 102 . The width of the third seal 107 is made equal to the width of the bottom portion of the leg portion 106 .

As shown in FIG. 10B, the third seal 107 seals the gap between the base portion 20B and the hatch cover 11, and damages (dents) the hatch cover 11 due to the base portion 20B being directly placed on the hatch cover 11. , scratches, etc.).

In the natural state shown in FIG. 10(A), the coil spring 108 is most stretched and the elastic member 102 is positioned below the third seal 107 . As shown in FIG. 10B, when the base portion 20B is placed on the hatch cover 11, the elastic member 102 is brought into contact with the hatch cover 11 and the coil spring 108 is contracted. At this time, the coil spring 108 urges the elastic member 102 toward the hatch cover 11 to press the elastic member 102 against the hatch cover 11 . Thereby, the gap between the base portion 20B and the hatch cover 11 is sealed.

In addition, the second seal 81 and the third seal 107 are provided over the entire length of the rail 19 .

Now, as shown in FIG. 9, when rainwater exists on the hatch cover 11 on the left side (the side opposite to the hatch opening) of the first seal 80, the flow of the rainwater toward the right side (the side opposite to the hatch opening) is first It is blocked by the first seal 80 .

Even if rainwater flows through the first seal 80 , the rainwater flow is blocked by the second seal 81 and the third seal 107 .

As shown in FIG. 10 , the second seal 81 has an elastic member 102 and a coil spring 108 as a biasing mechanism 103 . Therefore, the sealing performance can be significantly improved compared to the lip seal 150 of the comparative example.

That is, in the second seal 81, the coil spring 108 expands and contracts according to the size of the gap between the base portion 20B and the hatch cover 11, thereby bringing the elastic member 102 into contact with the hatch cover 11 and sealing the gap. At this time, since the expansion and contraction stroke of the coil spring 108 can be made large, the vertical movable range of the elastic member 102 can be made large, and the elastic member 102 can be kept in contact with the hatch cover 11 . As shown in FIG. 10(C), even if the gap between the base portion 20B (strictly speaking, the third seal 107) and the hatch cover 11 is large, the elastic member 102 is largely moved downward and brought into contact with the hatch cover 11. be able to. Moreover, the pressing force at this time can be optimally set by appropriately setting the spring constant of the coil spring 108 . Therefore, it is possible to prevent or suppress the inability to close the gap and the weakening of the surface pressure on the hatch cover 11, thereby significantly improving the sealing performance.

The mechanical spring in the biasing mechanism 103 may be a spring other than the coil spring 108, such as a plate spring or spiral spring. The elastic member 102 may be detachably attached to the biasing mechanism 103 . This allows the elastic member 102 to be replaced. Similarly, biasing mechanism 103 may be removably attached to base 20B. This allows the biasing mechanism 103 to be replaced.

Next, a modified example will be described. The description of the same parts as those of the basic embodiment will be omitted, and the differences from the basic embodiment will be mainly described below.

[First modification]
As shown in FIGS. 11 and 12, a second seal 81 similar to that described above is also provided in the first modification. However, unlike the basic embodiment, the second seal 81 is attached to the base 20B so as to be detachable from the side of the base 20B.

In the case of this modification, the second seal 81 is attached to the base 20B so as to be detachable from the left side (the side opposite to the hatch opening) of the base 20B. The left leg portion 106 is located on the right side of the basic embodiment, and the second seal 81 is detachably attached to the bottom surface of the mounting base portion 105 in the space on the left side of the left leg portion 106 .

The second seal 81 includes an elastic member 102 and a coil spring 108 similar to those described above. The second seal 81 also includes a mounting plate 109 to which the upper end of the coil spring 108 is fixed, and bolts 110 that fix the mounting plate 109 to the bottom surface of the mounting base 105 .

A bolt insertion hole 111 is provided in the mounting plate 109 at a position on the left side of the coil spring 108 , and a female threaded bolt hole 112 is provided in the bottom surface of the mounting base 105 . The bolt 110 is inserted through the bolt insertion hole 111 from below and then tightened into the bolt hole 112 . As a result, the mounting plate 109 and thus the second seal 81 are fixed to the base portion 20B. Although any type of bolt 110 may be used, for example, a hexagon socket head bolt can be used.

These bolt insertion holes 111 , bolt holes 112 and bolts 110 constitute bolt mounting portions 113 . A plurality of such bolt attachment portions 113 are provided at predetermined intervals in the longitudinal direction (front-rear direction) of the second seal 81 .

According to this modified example, in addition to the same effects as those of the basic embodiment, the following effects can be exhibited. That is, the second seal 81 can be attached/detached and replaced only by attaching/detaching the bolt 110 from the left side of the base portion 20B. Therefore, when the second seal 81 (especially the elastic member 102) deteriorates, the second seal 81 can be easily replaced.

In the case of the comparative example, the entire rain protection device must be placed on its side when replacing the lip seal 150, but this need not be done in the present modified example. Therefore, the replacement work is remarkably easy.

[Second modification]
As shown in FIG. 13, in the second modification, the biasing mechanism 103 of the second seal 81 includes a fluid spring. The biasing mechanism 103 of this embodiment is formed by an air spring 114, which is a type of fluid spring.

The air spring 114 has a piston 115 to which the elastic member 102 is fixed on the bottom surface, and a piston case 116 that accommodates the piston 115 so as to be vertically slidable. The upper end of the piston case 116 is open and fixed to the bottom surface of the mounting base 105 at a position between the pair of legs 106 . However, the biasing mechanism 103 and the base 104 may be detachable for replacement of the elastic member 102 .

A piston hole 117 through which the piston 115 can enter and exit is provided at the lower end of the piston case 116 . Stepped protrusions 118 and 119 are formed at the lower end of the piston case 116 and the upper end of the piston 115. These protrusions 118 and 119 are engaged with each other to prevent the piston 115 from slipping off, and to prevent the piston 115 from slipping off. A bottom dead center position is defined. A side surface of the projection 119 of the piston 115 slides on the inner surface of the piston case 116 .

The lower end of the piston 115 and the elastic member 102 have the same width so that the elastic member 102 can pass through the piston hole 117 when the piston 115 is raised.

The piston 115 , piston case 116 and elastic member 102 extend over the entire length of the rail 19 .

The second seal 81 has an air passage 120 for supplying compressed air to push down the piston 115 into the piston case 116 . The air passages 120 are provided inside the mounting base 105 and extend in the longitudinal direction (front-rear direction) of the mounting base 105 , and are provided at predetermined intervals in the longitudinal direction of the main passages 121 . A plurality of communication paths 122 (only one is shown) are provided. Compressed air is supplied to the main passage 121 from a supply source (air tank, compressor, etc.) not shown.

In this modified example, an air spring 114 instead of the coil spring 108 can be used to press the elastic member 102 against the hatch cover 11 to seal the gap. Since a large stroke of the piston 115 can be obtained, a large vertical movable range of the elastic member 102 can be obtained, and the elastic member 102 can be kept in contact with the hatch cover 11 . As shown in FIG. 13(C), even if the gap between the base portion 20B (strictly speaking, the third seal 107) and the hatch cover 11 is large, the elastic member 102 is largely moved downward and brought into contact with the hatch cover 11. be able to. Moreover, the pressing force at this time can be optimally set by appropriately setting the air pressure of the compressed air. Therefore, it is possible to prevent or suppress the inability to close the gap and the weakening of the surface pressure on the hatch cover 11, thereby significantly improving the sealing performance.

Moreover, since it is only necessary to supply compressed air to press the elastic member 102 against the hatch cover 11 only when it is in use, the supply of compressed air can be stopped and the pressing of the elastic member 102 can be stopped when the hatch cover 11 is not in use. Therefore, the durability of the elastic member 102 can be improved.

Also in this modified example, the second seal 81 may be attached to the base portion 20B so as to be detachable from the side of the base portion 20B. The fluid spring is not limited to the air spring 114, and may be, for example, a gas spring that uses a gas other than air as a working fluid, or a liquid spring that uses a liquid (for example, oil) as a working fluid.

Although the embodiments of the present disclosure have been described in detail above, various other embodiments and modifications of the present disclosure are conceivable.

For example, in the above-described embodiment, the main body of the device has a bellows structure and can be expanded and contracted. For example, the device main body may be of a fixed type that does not expand and contract. In this case, the device main body may be made of a relatively lightweight material such as resin (including FRP), aluminum, or the like.

The second seal 81 may be split longitudinally of the rail 19 . In this way, when the size of the gap between the base portion 20B and the hatch cover 11 changes according to the position of the rail 19 in the longitudinal direction, the elastic member 102 can be positioned at the optimum position according to the size of the gap at each position. can improve the sealing performance. In this case, the second seal 81 can be divided for each rail piece 21 .

In a first variant (FIG. 11), the relative placement of the second seal 81 with respect to the base 20B may be reversed. In other words, the second seal 81 may be arranged on the right side (hatch opening side) of the base portion 20B by reversing left and right.

The configurations of the above-described embodiments and modifications can be partially or wholly combined as long as there is no particular contradiction. Embodiments of the present disclosure are not limited to the above-described embodiments, and include all modifications, applications, and equivalents encompassed by the concept of the present disclosure defined by the claims. Accordingly, the present disclosure should not be construed in a restrictive manner, and can be applied to any other technology that falls within the spirit of the present disclosure.
