[0037] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present invention will be further described below with reference to the drawings and through specific implementation modes. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present invention are shown in the drawings, rather than all of them.

[0038] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components.

[0039] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature can include the first and second features being in direct contact, or can also include the first and second features not being in direct contact but being in contact through other features between them. Moreover, the first feature being "above", "above the", and "on the" of the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "below the", and "under the" of the second feature includes the first feature being directly below and obliquely below the second feature, or simply indicating that the first feature has a lower horizontal height than the second feature.

In addition, the terms "first" and "second" are only used for differentiation in description and have no special meaning.

[0041] The technical solutions of the present invention will be further described below with reference to the drawings and through specific implementation modes.

[0042] This embodiment discloses a ship, which is a scientific research ship or a test ship. Of course, the ship can also be other types of passenger ships or cargo ships, etc.

[0043] like Figure 1 As shown, this embodiment further discloses a work platform 10 . One or more laboratories 20 are provided on the ship. Multiple work platforms 10 are placed on the bottom plate of the laboratory 20 . Scientific researchers or crew members can complete various scientific research experiments and other tasks on the work platform 10 .

[0044] At present, the lower end surface of the working platform 10 is directly abutted against the bottom plate of the laboratory 20 to achieve a stable placement of the working platform 10 and avoid the influence of the shaking of the ship. When the working platform 10 needs to be moved, the working platform 10 is lifted onto a moving trolley or a moving plate, or universal wheels are installed at the bottom of the working platform 10, which makes the moving process of the working platform 10 more complicated, increases the workload, is not only time-consuming, but also easily causes damage to the working platform 10.

[0045] In order to solve the above problems, the present embodiment further discloses a moving structure of a working platform. The two opposite outer side walls of the working platform 10 are both provided with the moving structure of the working platform to achieve fast and flexible movement through the moving structure of the working platform.

[0046] Specifically, Figure 2 and Figure 3 As shown, the mobile structure of the working platform includes a caster 1, a support plate 2, a pull rod 3 and a locking block 4, and the support plate 2 is provided with the caster 1. A limit cavity (not shown in the figure) is provided in the working platform 10, and the pull rod 3 is rotatably provided in the limit cavity. One end of the pull rod 3 extends out of the limit cavity and is connected to the support plate 2, so that the support plate 2 can rotate between the stowed position and the deployed position relative to the working platform 10. When the support plate 2 is in the stowed position, the caster 1 is located above the support plate 2, and the lower end surface of the support plate 2 is higher than the lower end surface of the working platform 10. When the support plate 2 is in the deployed position, the caster 1 is located below the support plate 2, and the lower end surface of the support plate 2 is lower than or flush with the lower end surface of the working platform 10. The locking block 4 can lock the support plate 2 in the stowed position or the deployed position.

[0047] In this embodiment, when the working platform 10 needs to be fixed, the support plate 2 is in the retracted position, the casters 1 are located above the support plate 2, the locking block 4 locks the support plate 2 in the retracted position, and the lower end surface of the support plate 2 is higher than the lower end surface of the working platform 10, so that the lower end surface of the working platform 10 abuts against the bottom plate of the laboratory 20, realizing the stable placement of the working platform 10. When the working platform 10 needs to be moved, the support plate 2 is rotated from the retracted position to the deployed position. At this time, the lower end surface of the support plate 2 is lower than or flush with the lower end surface of the working platform 10, and the casters 1 are located below the support plate 2 to support the working platform 10, and the locking block 4 locks the support plate 2 in the deployed position. The working platform 10 is quickly and flexibly moved through the casters 1, improving the moving efficiency of the working platform 10.

[0048] It should be noted that four moving structures of the working platform are installed on the working platform 10 of this embodiment, and the four moving structures of the working platform are grouped in pairs. The two groups of moving structures of the working platform are respectively installed on two opposite outer side walls of the working platform 10, so that the working platform 10 is quickly moved through the four casters 1, improving the stability of the working platform 10 during the moving process.

[0049] As Figure 2 and Figure 3 shown, the support plate 2 includes a main plate 21 and a sub-plate 22. The main plate 21 is provided with casters 1 and is connected to the pull rod 3. The sub-plate 22 is arranged on the main plate 21, and a chute is formed inside the sub-plate 22. The locking block 4 is slidably arranged in the chute. The moving structure of the working platform further includes a first elastic member 5. A locking hole 101 is formed on the outer side wall of the working platform 10. The first elastic member 5 is used to drive the locking block 4 to pass through the locking hole 101 to lock the support plate 2 in the retracted position. The locking block 4 realizes the locking of the support plate 2 and the working platform 10 in the retracted position under the driving force of the first elastic member 5, improving the stability and reliability of the clamping fit between the locking block 4 and the working platform 10.

[0050] Specifically, a guiding groove 221 is concavely formed on the end surface of the sub-plate 22 opposite to the main plate 21, and the guiding groove 221 is communicated with the chute. One end of the locking block 4 extends upward to be provided with a handle 41, and two ends of the first elastic member 5 are respectively connected to the inner wall of the guiding groove 221 and the handle 41. The handle 41 passes through the sub-plate 22 from the guiding groove 221 and can slide along the guiding groove 221 to push the locking block 4 to disengage from the clamping connection with the working platform 10. While the handle 41 moves along the guiding groove 221, it can drive the locking block 4 to move synchronously along the chute. The locking block 4 can be manually disengaged from the clamping connection with the working platform 10 through the handle 41, thereby unlocking the support plate 2 in the retracted position.

[0051] The first elastic member 5 in this embodiment is a spring and is always in a compressed state. When the handle 41 is not subjected to an external force, the first elastic member 5 always has an elastic restoring force, thereby pushing the locking block 4 to firmly engage in the locking hole 101 of the working platform 10. When the handle 41 is manually toggled to move in the guiding groove 221 in a direction away from the working platform 10, the handle 41 squeezes the first elastic member 5 and drives the locking block 4 to be withdrawn from the locking hole 101, realizing the unlocking of the support plate 2 in the retracted position. By manually toggling the handle 41, the support plate 2 can be unlocked in the retracted position, with simple operation, convenient and fast.

[0052] As Figure 2 and Figure 3 shown, the main body plate 21 includes a vertical plate 211 and a horizontal plate 212. The vertical plate 211 is connected to the pull rod 3. The vertical plate 211 is closely attached to the outer side wall of the working platform 10 under the pulling of the pull rod 3, so that the main body plate 21 and the working platform 10 are compactly installed, reducing the floor area of the moving structure of the working platform. The horizontal plate 212 is connected to the vertical plate 211 to form an L shape. The auxiliary plate 22 and the casters 1 are both arranged on the horizontal plate 212. When the support plate 2 is in the retracted position, the horizontal plate 212 is above the vertical plate 211, and the lower end surface of the vertical plate 211 is flush with or higher than the lower end surface of the working platform 10, so that the lower end surface of the working platform 10 abuts against the bottom plate of the laboratory 20, realizing the stable placement of the working platform 10. When the locking block 4 unlocks the support plate 2 from the retracted position, the support plate 2 rotates 180° clockwise or counterclockwise, so that the support plate 2 rotates to the deployed position, and the horizontal plate 212 is below the vertical plate 211, and the lower end surface of the horizontal plate 212 is lower than or flush with the lower end surface of the working platform 10. At this time, the casters 1 are at the lowest position and abut against the bottom plate of the laboratory 20, enabling the working platform 10 to move quickly and flexibly through the casters 1.

[0053] It should be noted that when the support plate 2 is in the deployed position, the locking block 4 is in clamping fit with the lower end surface of the working platform 10 under the drive of the first elastic member 5. In this embodiment, when the support plate 2 is in the deployed position, the lower end surface of the horizontal plate 212 is flush with the lower end surface of the working platform 10, so that the auxiliary plate 22 is lower than the lower end surface of the working platform 10, and the upper end surface of the locking block 4 is coplanar with the lower end surface of the working platform 10. Thus, the locking block 4 extends below the lower end surface of the working platform 10 under the drive of the first elastic member 5, and the locking block 4 is firmly clamped to the lower end surface of the working platform 10, thereby locking the support plate 2 in the deployed position, avoiding the swing of the casters 1 during the movement of the working platform 10, and improving the stability and safety during the movement of the working platform 10.

[0054] As Figure 3As shown in the figure, the pull rod 3 includes a first rod 31 and a second rod 32. The first rod 31 is rotatably arranged in the limit cavity. One end of the first rod 31 extends out of the limit cavity and is connected to the second rod 32 to form a T-shaped rod. The second rod 32 is connected to the support plate 2, so that the support plate 2 can rotate at any angle relative to the working platform 10 around the axis of the first rod 31, enabling the support plate 2 to quickly switch between the retracted position and the deployed position.

[0055] Specifically, an avoidance groove 2111 is formed in the support plate 2. Two opposite inner side walls of the avoidance groove 2111 are provided with mounting holes 2112. The second rod 32 is located in the avoidance groove 2111, and both ends of the second rod 32 are rotatably inserted into the corresponding mounting holes 2112 respectively, that is, the second rod 32 is pivotally connected to the support plate 2, enabling the support plate 2 to further rotate around the axis of the second rod 32, so that there is a certain angle between the vertical plate 211 of the support plate 2 and the outer side wall of the working platform 10, facilitating the operator to push the lock block 4.

[0056] As Figure 3 shown in the figure, the moving structure of the working platform further includes a second elastic member 6. A first retaining ring 311 is fixedly arranged at the end of the first rod 31 away from the second rod 32. A second retaining ring 312 is movably sleeved on the first rod 31. The second elastic member 6 is located between the first retaining ring 311 and the second retaining ring 312, and the second elastic member 6 is always in a compressed state to pull the support plate 2 against the outer side wall of the working platform 10.

[0057] The second elastic member 6 in this embodiment is a spring and is always in a compressed state. The first retaining ring 311 is integrally connected to the first rod 31. The second elastic member 6 is slidably sleeved on the first rod 31. One end of the second elastic member 6 is connected to the second retaining ring 312, and the other end abuts against or is connected to the first retaining ring 311, enabling the second retaining ring 312 to slide along the axis of the first rod 31 to approach or move away from the first retaining ring 311.

[0058] When the support plate 2 is in the retracted position, the second elastic member 6 pushes the second retaining ring 312 against the inner side wall of the limiting cavity, so as to tension the support plate 2 by the pull rod 3, so that the vertical plate 211 is closely attached to the outer side wall of the working platform 10. The pull rod 3 and the locking block 4 realize the double fixation of the support plate 2 in the retracted position, further improving the stability and reliability of the support plate 2 in the retracted position. During the process of the support plate 2 rotating from the retracted position to the deployed position, after the locking block 4 unlocks the support plate 2 in the retracted position, manually pull the support plate 2 outwards, so that the support plate 2 is separated from the outer side wall of the working platform 10. The second elastic member 6 is compressed, and the length of the first rod 31 extending out of the limiting cavity increases, so that the vertical plate 211 of the support plate 2 will not rub against the outer side wall of the working platform 10, reducing the frictional resistance suffered by the support plate 2 during rotation, which is beneficial to the support plate 2 quickly rotating to the deployed position. When the support plate 2 rotates to the deployed position, release the support plate 2, the second elastic member 6 drives the first rod 31 to retract into the limiting cavity, and makes the vertical plate 211 closely attached to the outer side wall of the working platform 10 again, so that the pull rod 3 and the locking block 4 jointly realize the double fixation of the support plate 2 in the deployed position, further improving the stability and reliability of the support plate 2 in the deployed position.

[0059] It should be noted that when the support plate 2 is in the deployed position, only need to toggle the locking block 4 again, so that the locking block 4 is disengaged from the clamping connection with the lower end surface of the working platform 10, and then rotate the support plate 2 180° clockwise or counterclockwise around the axis of the first rod 31, so that the support plate 2 rotates to the retracted position, and the locking block 4 extends into the locking hole 101 again under the drive of the first elastic member 5, locking the support plate 2 in the retracted position again.

[0060] The caster 1 of this embodiment is a universal wheel, so as to facilitate the working platform 10 to move or turn in any direction through the caster 1.

[0061] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed.
