[0029] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0030] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figure 1As shown, in some embodiments of the present invention, a hatch 5 transport device is provided, including: a bottom support frame 1, a support assembly 2, a drive assembly 3, a rotating assembly 4, and a limiting assembly 6; the support assembly 2 is provided in two sets, and is respectively disposed at both ends of the bottom support frame 1 in the left-right direction; the drive assembly 3 is provided in two sets, and is respectively mounted on the two sets of support assemblies 2; the left and right ends of the rotating assembly 4 are respectively connected to the output ends of the two drive assemblies 3, the drive assembly 3 drives the rotating assembly 4 to rotate around a horizontal axis, the hatch 5 is fixedly installed on the rotating assembly 4, and the hatch 5 rotates with the rotating assembly 4 to have a horizontal state and a vertical state; the limiting assembly 6 is provided on the support assembly 2, and the limiting assembly 6 is provided in at least two sets, one set of limiting assembly 6 is located above the rotating assembly 4 in the horizontal state to be suitable for limiting and fixing the hatch 5 in the horizontal state; the other set of limiting assembly 6 is located on the front and rear sides of the rotating assembly 4 in the vertical state to be suitable for limiting and fixing the hatch 5 in the vertical state.

[0034] Specifically, the support assembly 2 is fixedly installed on the bottom support frame 1, the drive assembly 3 is fixedly installed on the support assembly 2, and the rotating assembly 4 is driven by the output end of the drive assembly 3. When the drive assembly 3 drives the rotating assembly 4 to rotate, it drives the hatch 5 to rotate, thus allowing the hatch 5 to have both a horizontal and a vertical state. At least two sets of limiting components 6 are provided on the support assembly 2. One set is located above the rotating assembly 4 in the horizontal state to limit and fix the hatch 5 in the horizontal state; the other set of limiting components 6 is located on the front and rear sides of the rotating assembly 4 in the vertical state to limit and fix the hatch 5 in the vertical state. This hatch 5 transport equipment, by driving the rotating assembly 4 to rotate through the drive assembly 3, changes the transport posture of the hatch 5, and simultaneously limits and fixes the rotating assembly 4 through the limiting components 6, thereby ensuring the safety of the hatch 5 during transport, improving structural reliability, and reducing the occurrence of safety accidents.

[0035] It is understandable that by setting two drive components 3 to drive the rotation of the rotating component 4 in the same direction, the force balance during the rotation of the rotating component 4 is ensured, thereby improving the stability and reliability of the structure. It should be noted that the drive component 3 includes a transmission component fixedly mounted on the bracket assembly, a drive wheel connected to the transmission component, and the output end of the transmission component connected to the left and right sides of the rotating component 4. The rotation of the drive wheel drives the transmission component to rotate, thereby driving the rotating component 4 to rotate. In some embodiments of the present invention, the transmission component is a worm gear reducer.

[0036] It is understood that the limiting components 6 can be uniformly disposed on any one of the support components 2, or disposed on two support components 2 respectively. In some embodiments of the present invention, each support component 2 is provided with two sets of limiting components 6, wherein the limiting components 6 on the two support components 2 are relatively distributed, thereby achieving uniform force limiting on the hatch 5, thereby improving the reliability and safety of the structure.

[0037] In some embodiments of the present invention, each set of limiting components 6 is provided with two, and the two limiting components 6 in each set are symmetrically distributed to uniformly apply force to the hatch 5, ensure the balance of force on the hatch 5, and improve the structural reliability.

[0038] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the limiting component 6 includes: a slide 61 and a slide plate 62. The slide 61 is disposed on the support component 2, and the slide 61 is provided with a groove 611 extending through both ends along the length direction. The slide plate 62 passes through the groove 611 and is adapted to extend and retract within the groove 611 to have an extended state for limiting and fixing the rotating component 4, and a retracted state for avoiding the rotating component 4. In the extended state, the extended end of the slide plate 62 is adapted to limit and fix the hatch 5 in a horizontal or vertical state. In the retracted state, the slide plate 62 is adapted to avoid the rotating component 4 so that the hatch 5 rotates with the rotating component 4.

[0039] It is understood that the limiting component 6 includes a slide table 61 and a sliding plate 62. The slide table 61 is provided with a groove 611 that runs through both ends along its length. The sliding plate 62 slides within the groove 611. When the rotating component 4 rotates to a horizontal or vertical position, the sliding plate 62 has an extended position that fixes and limits the rotating component 4. When the rotating component 4 needs to switch between a horizontal and a vertical position, the sliding plate 62 has a retracted position that avoids the rotating component 4, thereby ensuring that the hatch 5 rotates relative to the rotating component 4, so that the hatch 5 has multiple transport postures, improving transport efficiency and transport versatility.

[0040] Reference Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the slide table 61 is provided with limiting holes 612 that pass through the upper and lower sides along the height direction, and the slide plate 62 is provided with a plurality of positioning holes 621 evenly spaced along the length direction. The positioning holes 621 pass through the slide groove 611. The limiting component 6 also includes a positioning member 63, which passes through the limiting hole 612 and any positioning hole 621 to fix the slide plate 62 in the slide groove 611.

[0041] Specifically, by inserting the positioning member 63 through the limiting hole 612 and any positioning hole 621, the position of the slide plate 62 in the slide groove 611 is limited, thereby ensuring that the position of the rotating component 4 is limited by the slide plate 62 in the extended state. When the slide plate 62 needs to be in the retracted state, the positioning member 63 is pulled out from the limiting hole 612 and the positioning hole 621, so that the slide plate 62 can slide in the slide groove 611, realizing the transformation of the slide plate 62 in the extended state and the retracted state.

[0042] It should be noted that elastic blocks are provided at both ends of the slide plate 62 and an elastic block is provided on the side of the slide plate 62 near the rotating component 4 to reduce the impact force between the rotating component 4 and the slide plate 62, improve the service life of the slide plate 62, and reduce damage to the hatch 5.

[0043] In some embodiments of the present invention, the upper end of the slide table 61 is provided with a relief groove 613 that communicates with the slide groove 611. The limiting component 6 also includes a pusher 64, which is fixedly installed on the slide plate 62 and passes through the relief groove 613. The pusher 64 slides along the length direction of the relief groove 613 to drive the slide plate 62 to slide within the slide groove 611.

[0044] Specifically, a clearance groove 613 communicating with the sliding groove 611 is provided on the upper end surface of the slide table 61. The pusher 64 is fixedly installed on the slide plate 62 and passes through the clearance groove 613. The pusher 64 slides along the length of the clearance groove 613, thereby driving the slide plate 62 to slide. The pusher 64 improves the convenience of operation, thereby improving the efficiency of the slide plate 62 in switching between the extended and retracted states.

[0045] Reference Figure 5 As shown, in some embodiments of the present invention, the rotating component 4 includes: a main frame 41 and a locking component 42; the main frame 41 is adapted to fix the hatch 5, and the left and right ends of the main frame 41 are respectively connected to the output ends of two driving components 3; the locking component 42 is disposed on the main frame 41 and is correspondingly disposed with the limiting component 6, and the locking component 42 includes a telescopically adjustable lead screw 421, which is adapted to abut against the extended slide plate 62 to lock the main frame 41 in a horizontal or vertical state.

[0046] Specifically, the main frame 41 serves as the mounting body for the rotating assembly 4, providing a foundation for the installation of the hatch 5. The left and right sides of the main frame 41 are connected to the output ends of the drive assembly 3, and the rotation of the main frame 41 drives the hatch 5 to rotate. It is understood that locking assemblies 42 are provided on the main frame 41, with the locking assemblies 42 positioned opposite to the limiting assemblies 6, and the number of locking assemblies 42 matching the number of limiting assemblies 6, to ensure structural stability.

[0047] Reference Figure 6As shown, the locking assembly 42 includes a telescopically adjustable lead screw 421. When the slide plate 62 is in the extended state, the lead screw extends and abuts against the extended end of the slide plate 62, thereby locking the main frame 41 to ensure that the main frame 41 is in a fixed horizontal or vertical state during transportation, and to prevent the main frame 41 from shaking during transportation.

[0048] Reference Figure 6 As shown, in some embodiments of the present invention, the locking assembly 42 further includes: a fixed base 422 and a handwheel mechanism 423; the fixed base 422 is fixed on the main frame 41, and the fixed base 422 is provided with a through hole, a nut is fixedly installed in the through hole, and the lead screw 421 passes through the nut; the handwheel mechanism 423 is provided at one end of the lead screw 421, and the handwheel mechanism 423 drives the lead screw 421 to rotate so that the other end of the lead screw 421 abuts against the slide plate 62 in the extended state.

[0049] Specifically, the fixed base 422 is fixed on the main frame 41. The fixed base 422 has a through hole, and a nut is installed in the through hole. The lead screw 421 passes through the nut. The handwheel mechanism 423 is located at one end of the lead screw 421. By rotating the handwheel mechanism 423, the lead screw is driven to rotate, so that the other end of the lead screw 421 abuts against the extended slide plate 62, which is suitable for fixing the rotating component 4 and preventing the rotating component 4 from shaking.

[0050] In some embodiments of the present invention, the locking assembly 42 further includes a rotating rod 424, which is fixedly disposed at one end of the lead screw 421. The rotating rod 424 rotates so that the other end of the lead screw 421 abuts against the extended slide plate 62.

[0051] Specifically, by setting a rotating rod 424 at one end of the lead screw component 421, the ease of force application is increased, thereby improving the ease of driving the lead screw.

[0052] It is understandable that a locking assembly 42 is installed on the main frame 41, and the output end of the drive assembly 3 is connected to the left and right ends of the main frame 41 to drive the main frame 41 to rotate. When the main frame 41 is in a horizontal or vertical state, the limiting assembly 6 is in the extended state to limit and fix the main frame 41. The locking assembly 42 is equipped with a telescopically adjustable lead screw 421, which extends to abut against the sliding plate 62 of the locking assembly 42, thereby locking and fixing the main frame 41. By setting the locking assembly 42, the reliability and safety of the structure are further improved, ensuring the smooth transport of the hatch 5 and reducing the occurrence of safety accidents.

[0053] In some embodiments of the present invention, the rotating assembly 4 further includes: at least two fixed bases 43, and the two fixed bases 43 are respectively disposed on the left and right sides of the bottom of the main frame 41. The upper end surface of the fixed base 43 is provided with a height equalization pad, and a groove plate is provided above the height equalization pad. The fixing member is sequentially passed through the groove plate, the height equalization pad and the fixed base 43. The front and rear ends of the groove plate are provided with limit blocks, and an adjustment shaft is passed through the limit block. The adjustment shaft is adapted to extend and retract on the limit block to adjust the position parameters of the hatch 5.

[0054] Specifically, by setting equal-height pads on the fixed base 43, the height of the hatch 5 can be adjusted. By adjusting the extension and retraction of the shaft on the limit block, the front and rear position parameters of the hatch 5 can be adjusted, thereby adjusting the center of gravity of the hatch 5 so that the center of gravity is closer to the center of rotation, reducing the torque required for rotation and improving structural stability.

[0055] It is understandable that an auxiliary support plate is provided between the two fixed bases 43. There can be multiple auxiliary support plates, and the auxiliary support plates can slide at the bottom of the main frame 41, thereby improving the support force on the hatch 5, ensuring the force balance of the hatch 5, and improving the stability of the structure.

[0056] It is understandable that an adjustment and positioning component is provided at the bottom of the fixed base 43. The adjustment and positioning component passes through the fixed base 43 and one end of it abuts against the groove plate. By adjusting the height of the groove plate, it is suitable for adjusting the height of the hatch 5, thereby reducing the resistance torque required when the hatch 5 rotates.

[0057] In some embodiments of the present invention, the rotating assembly 4 further includes two support corner plates 44 disposed on the left and right sides of the main frame 41, and the support corner plates 44 are provided with an elastic plate on the side near the hatch 5.

[0058] Specifically, by installing an elastic plate on the support corner plate 44, the hard contact between the support corner plate 44 and the hatch 5 is reduced, thus preventing wear on the hatch 5. A slotted hole is provided on the main frame 41, through which fasteners pass and connect to the support corner plate 44. By adjusting the connection position of the fasteners, the positional parameters of the support corner plate 44 are adjusted to ensure the hatch 5 is securely fastened, thereby improving transportation stability.

[0059] Reference Figure 7As shown, in some embodiments of the present invention, the rotating assembly 4 further includes pressing assemblies 45 disposed on the left and right sides of the main frame 41. The pressing assembly 45 includes: a pressing fixing plate 451, a pressing ear plate 452, a shaft pin 453, and a pressing member 454. The pressing fixing plate 451 is disposed on the main frame 41 and has a shaft end limiting plate. One end of the pressing ear plate 452 is fixedly connected to the pressing fixing plate 451. The shaft pin 453 passes through the pressing ear plate 452 and is fixedly connected to the shaft end limiting plate at one end. The pressing member 454 is disposed at the other end of the shaft pin 453. The pressing member 454 rotates on the shaft pin 453 to drive the other end of the pressing ear plate 452 to move toward one side of the pressing fixing plate 451 to press the hatch 5.

[0060] Specifically, the clamping assembly 45 is used to clamp the hatch 5. During installation, one side of the hatch 5 is inserted into the clamping ear plate 452. By tightening the clamping member 454, the clamping ear plate 452 is pressed against the hatch 5 to fix the hatch 5. An elastic block is provided on the inner side of the clamping ear plate 452 to avoid hard contact between the clamping ear plate 452 and the hatch 5 and reduce wear on the hatch 5.

[0061] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
