Description

Technical Field

[0001] The present invention relates to the technical field of ship railings, and specifically relates to a multifunctional railing for ships. Background Art

[0002] Ship railings are important facilities to ensure the safety of crew members and passengers, mainly used to prevent people from falling, resist the impact of wind and waves, and provide temporary support. However, traditional ship railings have the following deficiencies: 1. Fixed height design: The height of most railings cannot be adjusted, making it difficult to adapt to different ship types or special operation requirements. For example, when loading and unloading goods or during emergency rescue, it is necessary to temporarily adjust the protection range. 2. Limited impact resistance: When a ship berths or encounters bad sea conditions, it is prone to collisions. Traditional railings lack a buffer structure, and long-term impacts are likely to cause deformation or damage, increasing maintenance costs. 3. Single function: Existing railings usually only have a protective function and cannot provide a temporary working platform or measures to prevent items from falling, lacking practicality. 4. Inconvenient installation and movement: Railings are mostly fixed by welding or bolts, which are time-consuming and laborious to disassemble and assemble, and lack flexibility when adjusting positions in narrow deck areas.

[0003] In view of this, we propose a multifunctional railing for ships. Summary of the Invention

[0025] Please refer to Figures 1-8 as shown, the present invention provides a technical solution: A multifunctional guardrail for a ship, comprising a fixed base 1, on which columns 2 are symmetrically arranged. On the opposite sides of the columns 2, a fixed box 3 is connected. Inside the fixed box 3, a height adjustment component 4 is arranged. The height adjustment component 4 can adjust the height of the guardrail to meet the needs of different people and different hulls. A moving groove 21 is opened on the outer side of the column 2, and a collision prevention device 5 is movably arranged between the two moving grooves 21 on both sides. Connection components 6 are arranged on both sides of the fixed base 1, and receiving grooves 11 are symmetrically opened at both ends of the bottom of the fixed base 1. A moving component 7 is arranged in the receiving grooves 11.

[0026] It should be noted that during installation, the fixed base 1 needs to be fixedly installed on the edge of the ship's deck. The moving component 7 is used to move the entire guardrail to a designated position for installation, and the connection components 6 are used to connect and fix two adjacent guardrails to ensure the stability of the entire device. The height adjustment component 4 can adjust the height of the guardrail, and the collision prevention device 5 can protect the guardrail and reduce the collision to the guardrail.

[0027] In this embodiment, the height adjustment component 4 includes a fixed frame 41. Inside the fixed frame 41, a plurality of rotating rods 42 are evenly and rotatably arranged. On both sides of the rotating rods 42, rotating plates 43 are symmetrically connected. On both sides of the fixed frame 41, lifting blocks 44 are arranged. In the middle of one lifting block 44, a first threaded hole 441 is opened, and in the middle of the other lifting block 44, a guiding hole 442 is opened. On both sides inside the fixed box 3, positioning grooves 31 are arranged. Inside one of the positioning grooves 31, a first threaded rod 32 is rotatably arranged, and inside the other positioning groove 31, a guiding rod 33 is arranged. One lifting block 44 is threadedly connected to the first threaded rod 32 through the first threaded hole 441, and the other lifting block 44 is movably sleeved on the guiding rod 33 through the guiding hole 442.

[0028] Furthermore, a receiving cavity 12 is opened at the top of the fixed base 1, and a first motor 121 is fixedly installed in the receiving cavity 12. The output end of the first motor 121 is fixedly connected to the bottom end of the first threaded rod 32.

[0029] During use, the first motor 121 controls the rotation of the first threaded rod 32, driving the lifting block 44 to move up and down, thereby controlling the lifting of the fixed frame 41. At the same time, the guide rod 33 limits the lifting of the fixed frame 41, so that the height of the guardrail can be adjusted to meet the requirements of different people and different hulls.

[0030] As a preferred embodiment of this embodiment, a second motor 411 is provided at the top of the fixed frame 41. A protective shell 4111 is fixedly sleeved outside the second motor 411. The output end of the second motor 411 is fixedly connected to the top end of one of the rotating rods 42. A gear 421 is fixedly sleeved at the top ends of the plurality of rotating rods 42, and adjacent two gears 421 are meshed with each other.

[0031] The second motor 411 controls the rotation of the rotating rod 42, driving the gear 421 fixedly sleeved at its top end to rotate, thereby driving the rotation of a plurality of meshed gears 421, causing the plurality of rotating plates 43 to rotate simultaneously. The protective shell 4111 protects the second motor 411.

[0032] Furthermore, a notch 431 is provided on one side of the rotating plate 43. When the plurality of rotating plates 43 rotate to the same plane, the notches 431 of adjacent rotating plates 43 are engaged with each other.

[0033] The rotation angle of the rotating plate 43 is controlled by the second motor 411, which is convenient for adjustment. And when the wind and waves are large, the plurality of rotating plates 43 can be rotated to the same plane to form a barrier to block the wind and waves.

[0034] In this embodiment, the column 2 is hollow inside. A second threaded rod 22 is rotatably arranged inside the column 2. A third motor 122 is fixedly installed in the accommodating cavity 12. The output end of the third motor 122 is fixedly connected to the bottom end of the second threaded rod 22. The anti-collision device 5 includes a connecting block 51 and a protection box 52. The connecting block 51 is threadedly connected to the second threaded rod 22. One end of the connecting block 51 passes through the moving groove 21 and is fixedly connected to the protection box 52. A sliding groove 521 is formed on one side of the protection box 52. A stop block 522 is slidably arranged in the sliding groove 521. A plurality of spring dampers 523 are uniformly arranged inside the protection box 52. One side of the stop block 522 is fixedly connected to the plurality of spring dampers 523.

[0035] When the hull docks or collides with other hulls, the stop block 522 slides into the inside of the sliding groove 521, squeezing the spring dampers 523 to protect the guardrail and extend the service life of the guardrail.

[0036] Further, protective plates 524 are arranged around the top of the protection box 52, a protection cavity 525 is formed inside the protective plates 524, and a buffer sponge pad is arranged on the inner wall of the protection cavity 525.

[0037] The protection cavity 525 is formed by the protective plates 524 at the top of the protection box 52. When a person's personal belongings accidentally fall beside the guardrail, the items will fall into the protection cavity 525, and the buffer sponge pad in the protection cavity 525 will protect the fallen items. Then, the third motor 122 is used to control the rotation of the second threaded rod 22, driving the connection block 51 to rise, so that the protection box 52 rises, facilitating the person to retrieve the fallen items.

[0038] In this embodiment, the connection assembly 6 includes a first connection ear 61 arranged on the left side of the left column 2 and a second connection ear 62 arranged on the right side of the right column 2. A second threaded hole 63 is formed in the middle of the first connection ear 61 and the second connection ear 62, and the bottom end of the first connection ear 61 and the top end of the second connection ear 62 are on the same horizontal plane.

[0039] When connecting, align the second threaded hole 63 of the first connection ear 61 of one guardrail with the threaded hole of the second connection ear 62 of another guardrail and fix them with bolts. In this embodiment, two sets of first connection ears 61 and second connection ears 62 are provided to make the connection more stable. And when one set of connection ears is damaged, it does not affect the normal use of the guardrail. In addition, the connection of the guardrails facilitates their maintenance and replacement, reducing the replacement cost.

[0040] In this embodiment, the moving assembly 7 includes an electric cylinder 71, an L-shaped rotating rod 72, a first connecting rod 73, a second connecting rod 74, and a universal wheel 75. The electric cylinder 71 is fixedly installed on the top of the fixed base 1. The telescopic end of the electric cylinder 71 is rotatably connected to two sets of L-shaped rotating rods 72. The other end of the L-shaped rotating rod 72 is rotatably connected to the first connecting rod 73. The other end of the first connecting rod 73 is provided with a universal wheel 75. The middle of the L-shaped rotating rod 72 is rotatably arranged on the side wall of the receiving groove 11. One end of the second connecting rod 74 is rotatably arranged on the side wall of the receiving groove 11, and the other end is rotatably connected to the middle of the first connecting rod 73.

[0041] By arranging the moving component 7 in the receiving groove 11, when it is necessary to move the guardrail, the universal wheel 75 is moved downward out of the receiving groove 11, which facilitates the overall movement and angle adjustment of the guardrail. After the position of the guardrail is fixed, the universal wheel 75 is hidden upward inside the receiving groove 11, which is convenient for fixedly installing the fixed base 1 on the hull deck. Specifically, the electric cylinder 71 stretches downward to drive one end of the L-shaped rotating rod 72 to rotate downward. The other end of the L-shaped rotating rod 72 drives the first connecting rod 73 to rotate, and at the same time, the second connecting rod 74 rotates synchronously to retract the universal wheel 75 upward. At this time, the fixed base 1 can be fixedly installed. When it is necessary to move the guardrail, the electric cylinder 71 is compressed in the reverse direction to drive the universal wheel 75 to move downward out of the receiving groove 11.

[0042] Furthermore, when an emergency occurs or when it is necessary to carry goods, the connection components 6 of two adjacent guardrails are opened, and the electric cylinder 71 is used to drive the universal wheel 75 to move downward out of the receiving groove 11, which is convenient for quickly opening the guardrail.

[0043] In this embodiment, a side plate 34 is hinged to the upper part of one side of the fixed box 3. Card slots 341 are symmetrically arranged at both ends of the side plate 34. Support plates 35 are symmetrically hinged to the lower part of one side of the fixed box 3. A clamping block 351 is arranged on one side of the support plate 35. The other ends of the side plate 34 and the support plates 35 are respectively connected to the inner side of the fixed box 3 through a snap structure. When the two support plates 35 rotate 90° to the left and right respectively and the side plate 34 flips downward 90°, the clamping block 351 is clamped in the card slot 341.

[0044] When a person needs to rest beside the guardrail, the two support plates 35 are rotated 90° to the left and right respectively, and the side plate 34 is flipped downward 90°. The two support plates 35 stably support the side plate 34, which is convenient for people to rest. Moreover, the side plate 34 and the support plates 35 are convenient to store and the operation is simple. It should be noted that the other ends of the side plate 34 and the support plates 35 are respectively connected to the inner side of the fixed box 3 through a snap structure. The snap structure is a fixed structure in the prior art, as long as it can satisfy the fixation of the side plate 34 and the support plates 35, and no special limitation is made here.

[0045] When the multifunctional guardrail for ships in this embodiment is in use, the electric cylinder 71 is compressed in the reverse direction to drive the universal wheel 75 to move downward out of the receiving groove 11. The guardrail is moved to a designated place through the universal wheel 75, and the angle with other guardrails is adjusted. Then, the universal wheel 75 is retracted by the electric cylinder 71; The adjacent two guardrails are fixedly connected by using the connection component 6, and the fixed base 1 of the guardrail is installed at the edge of the hull deck; The rotation of the first threaded rod 32 is controlled by the first motor 121, and the lifting block 44 is driven to lift, so as to control the lifting of the fixed frame 41. At the same time, the lifting of the fixed frame 41 is limited by the guide rod 33, so that the height of the guardrail can be adjusted to meet the requirements of different people and different hulls; When the hull docks or collides with other hulls, the stop block 522 slides into the inside of the sliding groove 521, squeezing the spring damper 523 to protect the guardrail and extend the service life of the guardrail.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
