Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more particularly to a transfer device. Background Technology

[0002] Due to their complex structure and dispersed geographical locations, ships typically employ transfer platforms for material transport. Generally, tracks and transfer platforms are fixed on the ship. The transfer platforms carry cargo and are powered by a motor to move along the tracks and deliver the cargo to its destination. Once the transfer platform is in position, the motor stops outputting power, causing the platform to sway due to the loss of power, potentially leading to damage to personnel and equipment. To ensure the stability of the transfer platform, a locking device is needed to lock it in place after it has reached its designated position.

[0003] In the prior art, a pin-type locking structure is usually used. For example, holes need to be made on both the transfer platform and the track. When the transfer platform reaches the target location, the holes on the transfer platform and the track are aligned, and then the pin is passed through the two holes in sequence to lock the transfer platform. However, the above locking method requires high alignment accuracy, and the locking position is fixed, with low design margin and poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a transfer device that enables the mobile platform to be locked at any position along the track throughout its journey, avoiding the limitations of traditional locking methods that require fixed openings, adapting to the needs of different operating scenarios, and significantly improving design margin.

[0005] To achieve this objective, the present invention adopts the following technical solution: A transfer device, comprising: A track, which extends along a first direction; A mobile platform, which is mounted on the track and is capable of moving along the first direction; A locking assembly has an active state and an idle state. When the locking assembly is in the active state, the relative positions of the track and the moving platform are locked. When the locking assembly is in the idle state, the track and the moving platform are unlocked. The locking assembly includes a rack and a latching member. The rack is disposed on the track and extends along the first direction. The latching member is movably disposed on the moving platform and can rotate in a plane perpendicular to the first direction to selectively engage or disengage with the rack, thereby placing the locking assembly in the active state or the idle state.

[0006] Preferably, the snap-fit ​​component includes a snap-fit ​​tooth portion and a connecting portion. The end of the connecting portion is connected to the snap-fit ​​tooth portion. The snap-fit ​​tooth portion is used to engage with the rack. The middle portion of the connecting portion is disposed on the moving platform via a pin. The pin extends along the first direction. The connecting portion is rotatable around the pin, so that the snap-fit ​​tooth portion selectively engages with or disengages from the rack.

[0007] Preferably, there are two racks and two locking members. The two racks and the two locking members are arranged in a one-to-one correspondence. The two racks are spaced apart and opposite to each other along the second direction. The two locking members are spaced apart along the second direction and the two locking teeth are located between the two racks. When the locking assembly is in the working state, the opposite sides of the two locking teeth engage with the two racks. When the locking assembly is in the idle state, the opposite sides of the two locking teeth separate from the two racks. The first direction and the second direction are arranged at an angle.

[0008] Preferably, the locking assembly further includes a driving member, the two output ends of which are respectively connected to the ends of the two connecting portions away from the locking teeth, for driving the two locking members to rotate, so that the two locking teeth move away from or closer to each other, until the opposite sides of the two locking teeth simultaneously engage with the two racks or until the opposite sides of the two locking teeth simultaneously separate from the two racks.

[0009] Preferably, the locking assembly further includes a retainer, the two ends of which are respectively connected to the ends of the two connecting portions away from the locking teeth. The retainer has a continuous tendency to contract, causing the two locking teeth to have a continuous tendency to move away from each other, thereby keeping the locking assembly in the working state.

[0010] Preferably, the retainer is a spring.

[0011] Preferably, the transfer device further includes a base, and the snap-fit ​​members and the moving platform are connected through the base. The base includes a connecting plate and a bracket. The connecting plate is connected to the moving platform, and the two snap-fit ​​members are rotatably connected to the bracket. The bracket is provided with two limiting protrusions spaced apart along the second direction. The two limiting protrusions are both located between the two snap-fit ​​members. When the locking component is in the idle state, the two limiting protrusions can respectively abut against the sides of the two snap-fit ​​members that are close to each other.

[0012] Preferably, the track is provided with a groove extending along the first direction, the two groove walls are spaced apart along the second direction, the two racks are respectively connected to the two groove walls, and the two groove walls gradually approach each other in the direction from the bottom of the groove to the opening of the groove, and the first direction and the second direction are set at an angle.

[0013] Preferably, the transfer device further includes a moving component, which includes a guide rail and rollers. The guide rail extends along the first direction and is connected to the bottom of the chute. The rollers are mounted on the moving platform via axles that extend along the second direction, and the rollers are capable of rolling on the guide rail.

[0014] Preferably, the roller is provided with two shoulders, which are spaced apart along the second direction, and the guide rail is located between the two shoulders.

[0015] The beneficial effects of this invention are: This invention proposes a transfer device, including a track, a moving platform, and a locking assembly. The track extends along a first direction, the moving platform is disposed on the track and is movable along the first direction, and the locking assembly has a working state and an idle state. When the locking assembly is in the working state, the relative positions of the track and the moving platform are locked. When the locking assembly is in the idle state, the track and the moving platform are unlocked. Specifically, the locking assembly includes a rack and a latching member. The rack is disposed on the track and extends along the first direction, and the latching member is movably disposed on the moving platform and is rotatable in a plane perpendicular to the first direction to selectively engage or disengage with the rack, thereby enabling the locking assembly to be in a working state and an idle state. The track extends along the first direction, providing a movement path for the mobile platform. The locking component has two working states. During the normal movement of the mobile platform, the locking component is in an idle state. At this time, the latch rotates to the position where it is separated from the rack, and the mobile platform can slide smoothly along the track without mechanical obstruction. When the mobile platform reaches the target position, the locking component switches to the working state. At this time, the latch rotates to the angle where it engages with the rack. The tooth surface engagement restricts the displacement of the mobile platform along the first direction, achieving rigid locking. In the above transfer device, the latch can engage with any tooth on the rack, thereby achieving locking of the mobile platform at any position along the entire track. This avoids the limitations of fixed openings, adapts to the needs of different operating scenarios, and significantly improves the design margin. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0022] Reference Figures 1 to 5 This embodiment proposes a transfer device, including a track 1, a moving platform 2, and a locking assembly 3. The track 1 extends along a first direction X1, the moving platform 2 is disposed on the track 1 and can move along the first direction X1, and the locking assembly 3 has a working state and an idle state. When the locking assembly 3 is in the working state, the relative positions of the track 1 and the moving platform 2 are locked. When the locking assembly 3 is in the idle state, the track 1 and the moving platform 2 are unlocked. Specifically, the locking assembly 3 includes a rack 31 and a latching member 32. The rack 31 extends along the first direction X1 and is disposed on the track 1, and the latching member 32 is movably disposed on the moving platform 2 and can rotate in a plane perpendicular to the first direction X1 to selectively engage or disengage with the rack 31, so that the locking assembly 3 is in a working state and an idle state. When the locking component 3 is in the working state, that is, when the locking component 3 performs the locking function, the track 1 and the moving platform 2 are relatively locked by the locking component 3, and the moving platform 2 cannot move along the first direction X1 on the track 1. When the locking component 3 is in the idle state, that is, when the locking component 3 does not perform the locking function, the track 1 and the moving platform 2 are unlocked, and the moving platform 2 can move along the track 1 along the first direction X1.

[0023] Track 1 extends along the first direction X1, providing a movement path for the mobile platform 2. The locking component 3 has two working states. During the normal movement of the mobile platform 2, the locking component 3 is in an idle state. At this time, the latching member 32 rotates to the position where it is separated from the rack 31, and the mobile platform 2 can slide smoothly along the track 1 without mechanical obstruction. When the mobile platform 2 reaches the target position, the locking component 3 switches to the working state. At this time, the latching member 32 rotates to the angle where it meshes with the rack 31. The meshing of the teeth restricts the displacement of the mobile platform 2 along the first direction X1, achieving rigid locking. In the above transfer device, the latching member 32 can mesh with any tooth on the rack 31, thereby achieving locking of the mobile platform 2 at any position along the entire length of the track 1. This avoids the limitations of fixed openings, adapts to the needs of different operating scenarios, and significantly improves the design margin.

[0024] The rack 31 extends along the first direction X1, and the teeth on the rack 31 are arranged along the first direction X1. The side wall of the locking member 32 is provided with a toothed groove, which can mesh with the teeth on the rack 31, so that the locking assembly 3 is in the working state and locks. The locking member 32 can rotate in a plane perpendicular to the first direction X1. When the locking member 32 rotates to mesh with the rack 31, the locking force between the locking member 32 and the rack 31 is perpendicular to the first direction X1, which can optimally resist the movement force along the first direction X1 and achieve maximum locking force.

[0025] Furthermore, the snap-fit ​​component 32 includes a snap-fit ​​tooth portion 321 and a connecting portion 322. The end of the connecting portion 322 is connected to the snap-fit ​​tooth portion 321. The snap-fit ​​tooth portion 321 is used to engage with the rack 31. The middle part of the connecting portion 322 is mounted on the moving platform 2 via a pin 33. The pin 33 extends along the first direction X1, and the connecting portion 322 can rotate around the pin 33, allowing the snap-fit ​​tooth portion 321 to selectively engage or disengage with the rack 31. The tooth groove on the snap-fit ​​component 32 is located on the snap-fit ​​tooth portion 321. The pin 33 extends along the first direction X1, allowing the connecting portion 322 to rotate in a plane perpendicular to the first direction X1 via the pin 33. The rotation of the snap-fit ​​component 32 utilizes the lever principle; only a small force is required at the end of the connecting portion 322 away from the snap-fit ​​tooth portion 321 to achieve the rotation of the snap-fit ​​component 32, thereby driving the snap-fit ​​tooth portion 321 to complete the engagement and disengagement actions with the rack 31. For example, when it is necessary to lock the mobile platform 2, force is applied to the end of the connecting part 322 away from the locking tooth part 321. The connecting part 322 rotates in a plane perpendicular to the first direction X1 with the pin 33 as the fulcrum, and simultaneously drives the locking tooth part 321 at the end to move closer to the rack 31. Finally, the tooth groove on the locking tooth part 321 and the tooth on the rack 31 are precisely engaged.

[0026] Optionally, the snap-fit ​​component 32 is composed of two parts: a connecting part 322 and a snap-fit ​​tooth part 321. Both the connecting part 322 and the snap-fit ​​tooth part 321 are block structures. The end of the connecting part 322 is connected to the end of the snap-fit ​​tooth part 321, and the connecting part 322 and the snap-fit ​​tooth part 321 are set at an angle. The snap-fit ​​component 32 is in the shape of a "7". The connecting part 322 and the snap-fit ​​tooth part 321 in the snap-fit ​​component 32 are integrally formed to ensure the overall strength of the snap-fit ​​component 32.

[0027] Furthermore, two racks 31 and two locking members 32 are provided, with each rack 31 and locking member 32 corresponding to the other. The two racks 31 are spaced apart and opposite each other along the second direction X2, and the two locking members 32 are spaced apart along the second direction X2 with two locking teeth 321 located between the two racks 31. When the locking assembly 3 is in the working state, the opposite sides of the two locking teeth 321 simultaneously engage with the two racks 31. When the locking assembly 3 is in the idle state, the opposite sides of the two locking teeth 321 simultaneously disengage from the two racks 31. The grooves on the two locking members 32 are located on the opposite sides of the two locking teeth 321, and the teeth on the two racks 31 are all located on the side facing the other rack 31. The two locking teeth 321 are located between the two racks 31, thus enabling double-sided locking. When it is necessary to lock the moving platform 2 and the track 1, the two locking members 32 rotate synchronously in a plane perpendicular to the first direction X1, so that the opposite sides of the locking teeth 321 of the two locking members 32 simultaneously engage with the corresponding racks 31. The double-sided engagement restricts the displacement of the moving platform 2 along the first direction X1, thus completing the relative locking of the track 1 and the moving platform 2. The above-mentioned double-sided engagement design allows the locking force between the locking members 32 and the racks 31 to be evenly distributed on the two sets of racks 31 and locking members 32, maintaining force balance and avoiding the situation of force concentration in unilateral engagement. This prevents deformation and damage to the locking teeth 321 of the locking members 32 or the racks 31, effectively extending the service life of the locking assembly 3.

[0028] In this embodiment, the first direction X1 and the second direction X2 are set at an angle. The second direction X2 is located in a plane perpendicular to the first direction X1, that is, the first direction X1 is perpendicular to the second direction X2.

[0029] To achieve synchronous rotation of the two locking members 32, the locking assembly 3 also includes a driving member 34. The two output ends of the driving member 34 are respectively connected to the ends of the two connecting parts 322 away from the locking teeth 321, and are used to drive the two locking members 32 to rotate, so that the two locking teeth 321 move away from each other or move closer to each other, until the opposite sides of the two locking teeth 321 simultaneously engage with the two racks 31 or until the opposite sides of the two locking teeth 321 simultaneously separate from the two racks 31. When it is necessary to lock the mobile platform 2 and the track 1 relative to each other, the two output ends of the drive member 34 retract simultaneously, driving the two locking members 32 to rotate in a plane perpendicular to the first direction X1. At this time, the ends of the two connecting parts 322 away from the locking teeth 321 move closer to each other, thereby causing the two locking teeth 321 to move away from each other until the opposite sides of the two locking teeth 321 engage with the two racks 31 simultaneously, and the locking assembly 3 enters the working state to achieve locking. When it is necessary to unlock the mobile platform 2 and the track 1, the two output ends of the drive member 34 extend simultaneously, driving the two locking members 32 to rotate in a plane perpendicular to the first direction X1. At this time, the ends of the two connecting parts 322 away from the locking teeth 321 move away from each other, thereby causing the two locking teeth 321 to move closer to each other until the opposite sides of the two locking teeth 321 disengage from the two racks 31 simultaneously, and the locking assembly 3 enters the idle state to achieve unlocking. Optionally, the drive member 34 can be a hydraulic cylinder. Each of the two connecting parts 322 has a first connecting seat 323 on one side facing each other, and the two output ends of the driving member 34 are respectively fixedly connected to the two first connecting seats 323. In more embodiments, the driving member 34 can also be a large motor.

[0030] Furthermore, to ensure the stability of the locking assembly 3 when it is in operation, the locking assembly 3 also includes a retaining member 35. The two ends of the retaining member 35 are respectively connected to the ends of the two connecting portions 322 away from the locking teeth 321. The retaining member 35 has a continuous contraction tendency, causing the two locking teeth 321 to have a continuous tendency to move away from each other, thereby keeping the locking assembly 3 in the working state. When the locking assembly 3 is in the working state, the driving member 34 completes the driving and the two locking teeth 321 engage with the two racks 31. The retaining member 35, with its continuous contraction tendency, applies opposing pulling forces to the ends of the two connecting portions 322 away from the locking teeth 321, causing the two connecting portions 322 to move closer to each other. This tendency causes the two locking teeth 321 to have an outward pushing force, keeping the two locking teeth 321 always in a state of moving away from each other. Thus, the sides of the two locking teeth 321 that are moving away from each other are firmly engaged with the corresponding racks 31, achieving stable operation of the locking assembly 3. The combination of the inward driving force of the drive component 34 and the contraction force of the retainer 35 forms a double locking guarantee. Even if the drive component 34 fails during operation and cannot continue to provide locking power, the retainer 35 can still maintain the meshing of the toothed part 321 and the rack 31 by relying on the contraction tension, so as to avoid the uncontrolled sliding of the moving platform 2 and greatly improve the operating safety factor of the entire transfer device.

[0031] Additionally, it is understandable that when unlocking is required, the drive member 34 outputs sufficient driving force to overcome the contraction tension of the retainer 35, thereby pushing the two connecting parts 322 away from each other, thereby causing the two locking teeth 321 to move closer to each other to disengage from the rack 31.

[0032] Optionally, the retainer 35 is a spring, with both ends connected to the connecting portions 322 of the two latching members 32. When the driving member 34 drives the two latching members 32 to complete the engagement action, the spring is in a stretched state. Its contraction and rebound force will exert opposing tensions on the two connecting portions 322. The tension is transmitted to the latching teeth 321 through the connecting portions 322, so that the two latching teeth 321 have an outward expanding thrust, ensuring that the latching teeth 321 are always firmly engaged with the rack 31. A second connecting seat 324 is provided on the side of each of the two connecting portions 322 facing each other, and both ends of the spring are fixedly connected to the two second connecting seats 324.

[0033] Reference Figure 1 and Figure 4The transfer device also includes a base 4, with the locking components 32 and the moving platform 2 connected via the base 4. The base 4 includes a connecting plate 41 and a bracket 42. The connecting plate 41 is connected to the moving platform 2, and the two locking components 32 are rotatably connected to the bracket 42. The bracket 42 is provided with two limiting protrusions 421 spaced apart along the second direction X2. Both limiting protrusions 421 are located between the two locking components 32. When the locking assembly 3 is in an idle state, the two limiting protrusions 421 can respectively abut against the sides of the two locking components 32 that are close to each other. The plates of the connecting plate 41 and the moving platform 2 are arranged relatively parallel, and the connecting plate 41 and the moving platform 2 are fixedly connected by multiple screws. The bracket 42 is provided with two limiting protrusions 421. When the locking assembly 3 is in an idle state, that is, when the locking components 32 are separated from the rack 31, the two limiting protrusions 421 respectively abut against the sides of the locking components 32 that are close to each other, preventing the two locking components 32 from accidentally colliding and causing damage. Optionally, flexible pads can also be provided on both limiting protrusions 421 to ensure flexible contact when the locking member 32 abuts against the limiting protrusion 421, further protecting the limiting protrusion 421. It should be explained that when the locking assembly 3 is in the idle state, the locking teeth 321 on the locking member 32 are completely disengaged from the rack 31, and at this time, the two limiting protrusions 421 abut against the sides of the two locking members 32 that are close to each other. Therefore, the two limiting protrusions 421 can also provide a clear reference position for the locking member 32. When the locking assembly 3 switches back to the working state, the locking member 32 can quickly rotate from the stable reference position to the engagement state with the rack 31, shortening the response time.

[0034] Additionally, refer to Figure 1 , Figure 4 and Figure 5 The track 1 is provided with a groove 11 extending along the first direction X1. The two groove walls of the groove 11 are spaced apart along the second direction X2. Two racks 31 are respectively connected to the two groove walls. The groove 11 extends from the bottom to the opening, and the two groove walls gradually approach each other. The groove 11 has a narrower top and wider bottom from the opening to the bottom. The cross-section of the groove 11 is an inverted trapezoid. The two racks 31 are respectively connected to the two groove walls, and both racks 31 are inclined and close to each other on the same side. Therefore, when the engaging member 32 engages with the racks 31, the inclined racks 31 can restrict the lateral movement of the racks 31, ensuring that the engaging part 321 and the racks 31 always maintain good engagement. The first direction X1 and the second direction X2 are set at an angle. In this embodiment, the first direction X1 and the second direction X2 are set perpendicularly.

[0035] Furthermore, the rack 31 and the groove wall of the slide 11 are connected by bolts. A connecting groove is provided on the side of the rack 31 away from the teeth. The bottom of the connecting groove and the teeth on the rack 31 are spaced apart. The bolts are placed in the connecting groove to fix the rack 31 to the groove wall of the slide 11.

[0036] The transfer device also includes a moving component, which comprises a guide rail 51 and rollers 52. The guide rail 51 extends along a first direction X1 and is connected to the bottom of the chute 11. The rollers 52 are mounted on the moving platform 2 via axles 53, which extend along a second direction X2, allowing the rollers 52 to roll on the guide rail 51. The guide rail 51 provides guidance for the movement of the moving platform 2, ensuring that the movement path of the moving platform 2 is completely parallel to the track 1, thus guaranteeing the smooth operation of the moving platform 2. The guide rail 51 has an "I"-shaped cross-section and is fixed to the bottom of the chute 11 by bolts.

[0037] Optionally, the roller 52 is provided with two shoulders 521, which are spaced apart along the second direction. The guide rail 51 is located between the two shoulders 521 to ensure the stability of the roller 52 when it moves on the guide rail 51. In this embodiment, the two shoulders 521 are respectively provided at both ends of the roller 52. When the roller 52 rolls on the guide rail 51, the guide rail 51 is located between the two shoulders 521 to prevent the guide rail 51 and the roller 52 from shifting.

[0038] To ensure the stability of the moving components, two rollers 52 are provided. Further, the bracket 42 includes two mounting frames 422, spaced apart along a first direction X1. The openings of the two mounting frames 422 are opposite in the first direction X1. The two rollers 52 are respectively mounted inside the two mounting frames 422, and the axle 53 passes through the mounting frames 422 to connect the rollers 52 inside the mounting frames 422. The two mounting frames 422 are spaced apart along the first direction X1, thus leaving a mounting area between them. Both snap-fit ​​pieces 32 are located in the mounting area. The pin 33 extends along the first direction X1 and passes through the frame walls of the two mounting frames 422 to connect the snap-fit ​​pieces 32 within the mounting area. Both limiting protrusions 421 are located within the mounting area to limit the movement of the two snap-fit ​​pieces 32. The two limiting protrusions 421 are both located on the outer wall of the mounting frame 422, i.e., on the side of the mounting frame 422 closest to the snap-fit ​​pieces 32.

[0039] Furthermore, the transfer device proposed in this embodiment can be specifically applied to ships to realize the transportation of goods on ships. Specifically, the transfer device is installed on a ship, the mobile platform 2 moves and locks on the track 1, the mobile platform 2 can carry goods, and thus transfer goods on the ship. In the ship environment, when the locking component 3 enters the working state, it can lock the mobile platform 2 to the track 1 to prevent the goods from slipping and tipping over, reduce the risk of accidents, and has high stability and safety.

[0040] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
