Description

Technical Field

[0001] This invention relates to the field of hatch cover technology, specifically to a protective tooling for hatch covers. Background Technology

[0002] A hatch is a door or lattice cover that allows vertical access to a ship's hold. It is an opening on the ship's deck for loading and unloading cargo, machinery, or personnel. Hatches are usually equipped with hatch covers, which are devices used to seal hatches on a ship.

[0003] When using hatch covers, some hatch covers are installed above the hatch surface to prevent rainwater from entering. However, if the hatch cover is accidentally bumped during the handling of cargo containers, it can easily deform, reducing the internal space and causing the inner wall to fit tightly against the protrusion, making it difficult to open. Furthermore, once opened, the hatch cover may come into contact with the ship's surface or the ground. Due to its weight, this contact can easily cause damage to the surface of the hatch cover. Summary of the Invention

[0004] The purpose of this invention is to provide a protective tooling for hatch covers to solve the problems existing in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a protective fixture for a hatch cover, comprising a hatch cover body and a cover plate, and further comprising:

[0006] A connecting plate is fixedly connected to the front and rear left sides of the hatch cover body. A fixing rod is rotatably connected inside the connecting plate, and the surface of the fixing rod is fixed to the connecting end of the cover plate.

[0007] A fixing plate is fixed on the right side of the cover plate. The surface of the fixing plate has a groove, and a first airbag is arranged around the inner side of the groove. A second airbag is arranged inside the hatch cover body, and a limiting protrusion is provided above the second airbag. A connecting pipe is connected between the front and rear sides of the top left side of the second airbag and the first airbag.

[0008] The convex plate on the right side of the fixed plate is fixed by bolts. The front and rear sides of both sides of the convex plate are rotatably connected to screws. The surface of the screws is threaded with a fixing sleeve. The other end of the fixing sleeve extends to the outside of the convex plate and is fixed to one side of the abutment plate.

[0009] A force-applying structure disposed on the outside of the convex plate and used to drive the screw to rotate;

[0010] A support plate is movably connected to the surface of the hatch cover body and is used to protect the cover plate. A transmission structure for moving the support plate is provided between the support plate and the fixed rod.

[0011] A buffer structure is located on the left side of the top of the support plate and is used to cushion the cover plate.

[0012] Preferably, the force-applying structure includes turntables respectively disposed on the outer and inner sides of the cover plate, a rotating rod with both ends fixed to opposite sides of the two turntables, a conical gear disk fixed on the surface of the rotating rod, and a first conical gear fixed to one end of the screw, wherein the first conical gear meshes with the surface of the conical gear disk.

[0013] Preferably, the buffer structure includes a round rod movably connected to the front and rear sides inside the support plate, a buffer plate fixed to one end of the round rod, and a spring sleeved on the surface of the round rod, wherein the two ends of the spring are respectively fixed to the top of the buffer plate and the support plate.

[0014] Preferably, the transmission structure includes a second bevel gear fixed at both ends of the fixed rod, a third bevel gear meshing with the surface of the second bevel gear, a transmission rod fixed on the other side of the third bevel gear, a gear fixed at the other end of the transmission rod, and a plurality of teeth fixed on the front and rear sides of the support plate, wherein the support plate meshes with the gear through the teeth.

[0015] Preferably, the hatch cover body has sliding grooves on both the front and rear sides, and the inner sides of both ends of the support plate are fixedly connected to sliders, the surface of the sliders being movably connected to the inside of the sliding grooves.

[0016] Preferably, limiting plates are fixedly connected to both the front and rear sides of the hatch cover body, and the interior of the limiting plates is movably connected to the surface of the support plate.

[0017] Preferably, an indicator rod is fixedly connected to the top of one end of the turntable, and baffles for limiting the position of the indicator rod are fixed on both the upper and lower sides of the left side of the cover plate.

[0018] Preferably, each of the four sides of the convex plate is movably connected with a movable rod, and one end of the movable rod is fixed to one side of the abutment plate.

[0019] Preferably, a limiting groove is formed on the left and right sides of both sides of the inner cavity of the convex plate, and a limiting block is fixedly connected to both sides of the fixed sleeve, with the surface of the limiting block being movably connected to the inside of the limiting groove.

[0020] Preferably, a support plate is fixedly connected to both the front and rear sides of the left side of the hatch cover body, and the interior of the support plate is rotatably connected to the surface of the transmission rod.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. When the hatch cover body is deformed by external force, the present invention can rotate the screw through the force-applying structure, which can drive the fixed sleeve and the abutment to move, so that the size between the protruding plate and the abutment is deformed, and the space inside the hatch cover body becomes larger. At this time, the cover can be easily opened from the inside of the hatch cover body.

[0023] 2. After the cover plate and the hatch cover body are closed, the present invention uses a force-applying structure to drive the movement of the abutment plate. When the abutment plate contacts and fixes itself to the inner wall of the hatch cover body, it can compress the second airbag, so that the gas inside the second airbag is transported to the inside of the first airbag through the connecting pipe. At this time, the first airbag will inflate, and the inflated first airbag will contact the inner wall of the hatch cover body, thereby improving the sealing effect after closure.

[0024] 3. After the cover plate is opened, the transmission structure can drive the support plate to move to the left. As the deflection angle of the cover plate increases, the support plate will contact one end of the cover plate, thereby facilitating the support and protection of the cover plate and preventing it from being worn against the ground or the hull.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-7 A protective fixture for a hatch cover includes a hatch cover body 1 and a cover plate 4. Connecting plates 2 are fixedly connected to the front and rear sides of the left side of the hatch cover body 1. A fixing rod 3 is rotatably connected inside the connecting plate 2, and the surface of the fixing rod 3 is fixed to the connecting end of the cover plate 4. A fixing plate 5 is fixed to the right side of the cover plate 4. A groove 6 is formed on the surface of the fixing plate 5, and a first airbag 7 is arranged around the inner side of the groove 6. A second airbag 8 is arranged inside the hatch cover body 1, and a limiting protrusion 24 is provided above the second airbag 8. A connecting pipe 9 connects the front and rear sides of the top left side of the second airbag 8 to the first airbag 7. The right side of the fixing plate 5 is fixed by bolts. A convex plate 10 is connected, and screws 11 are rotatably connected to the front and rear sides of both sides inside the convex plate 10. A fixing sleeve 12 is threadedly connected to the surface of the screw 11. The other end of the fixing sleeve 12 extends to the outside of the convex plate 10 and is fixed to one side of the abutment plate 13. A force-applying structure 14 for driving the screws 11 to rotate is provided on the outside of the convex plate 10. A support plate 18 for protecting the cover plate 4 is movably connected to the surface of the hatch cover body 1. A transmission structure 20 for driving the support plate 18 to move is provided between the support plate 18 and the fixing rod 3. A buffer structure 19 for buffering the cover plate 4 is provided on the left side of the top of the support plate 18.

[0035] The force-applying structure 14 includes a turntable 141, a rotating rod 142, a bevel gear disk 143, and a first bevel gear 144. There are two turntables 141, which are respectively located on the outer and inner sides of the cover plate 4. The surface of the rotating rod 142 penetrates the interior of the protruding plate 10, the cover plate 4, and the fixing plate 5, and both ends of the rotating rod 142 are fixed to the two turntables 141 respectively. The bevel gear disk 143 is fixed to the surface of the rotating rod 142. There are several first bevel gears 144, and they all mesh with the surface of the bevel gear disk 143. One side of the first bevel gear 144 is fixed to one end of the screw 11. Thus, when the screw 11 is driven to rotate, the turntable 141 can be rotated, which drives the rotating rod 142 to rotate, and at the same time drives the bevel gear disk 143 to rotate, and drives several first bevel gears 144 to rotate on the surface of the bevel gear disk 143, thereby driving the screw 11 to rotate.

[0036] The buffer structure 19 includes a round rod 191, a buffer plate 192, and a spring 193. There are two round rods 191, and they are movably connected to the front and rear sides inside the support plate 18. The top of the round rod 191 is fixed to the bottom of the buffer plate 192. The spring 193 is sleeved on the surface of the buffer plate 192, and the two ends of the spring 193 are fixed to the top of the buffer plate 192 and the top of the support plate 18, respectively. After the cover plate 4 falls, it will contact the top surface of the buffer plate 192 and exert downward force on the buffer plate 192. At this time, the downward pressure on the buffer plate 192 can be reduced by the elastic force of the spring 193 itself, thereby facilitating the protection of the cover plate 4.

[0037] The transmission structure 20 includes a second bevel gear 201, a third bevel gear 202, a transmission rod 203, a gear 204, and teeth 205. The second bevel gear 201 is fixed to both ends of the fixed rod 3. One side of the third bevel gear 202 meshes with the second bevel gear 201. The bottom of the third bevel gear 202 is fixed to one end of the transmission rod 203, and the other end of the transmission rod 203 is fixed to one side of the gear 204. There are several teeth 205, all of which are fixed to the front and rear sides of the support plate 18. Plate 18 meshes with gear 204 through teeth 205. When cover plate 4 is opened, it will drive the fixing rod 3 to rotate inside the connecting plate 2. As the fixing rod 3 rotates, it will drive the second bevel gear 201 to rotate as well, and drive the third bevel gear 202, transmission rod 203 and gear 204 to rotate. Then, through teeth 205, it will drive the support plate 18 to move to the left until the left side of cover plate 4 contacts the top surface of support plate 18, thereby preventing cover plate 4 from contacting the hull or the ground.

[0038] The hatch cover body 1 has sliding grooves 22 on both the front and rear sides. The inner sides of both ends of the support plate 18 are fixedly connected to sliders 23. The surface of the sliders 23 is movably connected to the inside of the sliding grooves 22, so as to provide auxiliary limit for the support plate 18 and facilitate its movement.

[0039] Limiting plates 21 are fixedly connected to both the front and rear sides of the hatch cover body 1. The interior of the limiting plates 21 is movably connected to the surface of the support plate 18, so as to provide auxiliary support for the support plate 18 and maintain its stability when moving.

[0040] An indicator rod 25 is fixedly connected to the top of one end of the turntable 141. Baffles 26 for limiting the position of the indicator rod 25 are fixed on the upper and lower sides of the left side of the cover plate 4. This can limit the rotation range of the turntable 141, the rotating rod 142 and the bevel gear disk 143, making it convenient for staff to understand the rotation position.

[0041] Movable rods 15 are movably connected to all four sides of the protruding plate 10. One end of the movable rod 15 is fixed to one side of the abutment plate 13, which can provide auxiliary support for the abutment plate 13 and maintain its stability when moving.

[0042] Limiting grooves 16 are provided on the left and right sides of the inner cavity of the convex plate 10. Limiting blocks 17 are fixedly connected to both sides of the fixed sleeve 12. The surface of the limiting block 17 is movably connected to the inside of the limiting groove 16. This can provide auxiliary limiting for the fixed sleeve 12 and prevent the fixed sleeve 12 from moving excessively from the surface of the screw 11.

[0043] Support plates 27 are fixedly connected to the front and rear sides of the left side of the hatch cover body 1. The interior of the support plate 27 is rotatably connected to the surface of the transmission rod 203, so as to provide auxiliary support for the transmission rod 203 and maintain its stability during rotation.

[0044] It should be noted that the expansion coefficient of the first airbag 7 is greater than that of the second airbag 8. Therefore, when the first airbag 7 and the second airbag 8 are subjected to uniform force, the gas will enter the interior of the second airbag 8 and expand.

[0045] Working principle: In use, after the cover plate 4 is placed on the top surface of the hatch cover body 1, the abutment plate 13 at the protruding plate 10 is flush with the second airbag 8. The screw 11 can be rotated by the force application structure 14, which in turn drives the fixing sleeve 12 and the abutment plate 13 to move outward, causing the abutment plate 13 to move towards one side of the second airbag 8 and compress the second airbag 8. After being compressed, the second airbag 8 will transport the gas inside it to the inside of the first airbag 7 through the connecting pipe 9, so that the first airbag 7 can inflate. The inflated first airbag 7 and the hatch cover body are then connected. The inner wall of 1 is fitted together to improve the sealing effect. If the hatch cover body 1 is deformed under the action of external force, in order to facilitate the opening of the cover plate 4, the screw 11 and the fixing sleeve 12 can be driven back to the starting position by the force application structure 14, thereby reducing the size of the protruding plate 10, so as to facilitate the opening of the cover plate 4. As the cover plate 4 is opened, the fixing rod 3 will be driven to rotate, and the support plate 18 will be driven to move to the left through the transmission structure 20 until one end of the left side of the cover plate 4 contacts the support plate 18, and the cover plate 4 can be supported and protected by the buffer structure 19.
