Description

Technical Field

[0001] This utility model relates to the field of transfer equipment, and in particular to a port transfer equipment with an anti-slip structure. Background Technology

[0002] In shipping, goods with different physical characteristics are generally stored in different containers. Grain needs to be protected from moisture absorption, mold growth, and insect and rodent damage during transportation. In particular, starch needs to be packaged and sealed in separate containers. When transporting starch, storage barrels are used to store it, which can effectively prevent starch from getting damp and being damaged by insects and rodents. If the starch in a single storage barrel deteriorates, it will not affect other storage barrels, thus reducing cargo loss during shipping.

[0003] Currently, ports extensively use AGVs to transport cargo when it is loaded onto ships, reducing manual management. Most of the cargo carried by existing AGVs is rectangular, such as containers, which have a large bottom contact area and are not easy to slip off the AGV. However, storage barrels are cylindrical, with a small bottom contact area and a tall body. When the AGV travels too fast, the storage barrels are easy to slip off the AGV, causing the AGV to stop working and requiring worker intervention to clear the obstruction, thus affecting the transfer efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a port transfer device with an anti-slip structure, which uses two clamping mechanisms to clamp the storage barrels when the AGV is moving, thus preventing the storage barrels from slipping off the AGV.

[0006] The device includes a traveling device, a frame, and two lead screw mechanisms. The frame is fixedly connected to the top of the traveling device. A reciprocating mechanism is provided on the frame, and a support plate is slidably connected to the reciprocating mechanism. The two lead screw mechanisms are respectively connected to both sides of the frame, and a clamping mechanism is slidably connected to the lead screw mechanism. The two clamping mechanisms are opposite to each other, forming a clamping area between them. The support plate is located below the clamping area. Each clamping mechanism includes a connecting seat and two first clamping arms. The connecting seat is slidably connected to the lead screw mechanism. A first gear and a second gear are rotatably connected to the connecting seat. The first gear and the second gear are engaged. A clamping motor is provided on the connecting seat, and the output shaft of the clamping motor is connected to the first gear. The first clamping arms are rotatably connected to the connecting seat, and a third gear is provided on the first clamping arm. The two third gears are engaged with the first gear and the second gear, respectively. A contact wheel is provided on the first clamping arm, and the contact wheel is close to the clamping area.

[0007] As a preferred embodiment, a second clamping arm is rotatably connected to the first clamping arm, the contact wheel is rotatably connected to the second clamping arm, a connecting rod is rotatably connected to the second clamping arm, and the connecting rod is rotatably connected to the connecting seat.

[0008] As a preferred embodiment, the frame is provided with a support platform, and the reciprocating mechanism includes a mounting base, a sliding plate, and a drive assembly. The mounting base is placed on the support platform, the sliding plate is slidably connected to the mounting base, the support plate is slidably connected to the sliding plate, the drive assembly is connected to the mounting base, and a chain is sleeved on the drive assembly. Both ends of the chain are fixedly connected to the support plate.

[0009] As a preferred embodiment, the drive assembly includes a reciprocating bracket and a drive motor. A first ratchet is rotatably connected to the reciprocating bracket, and a central shaft extends from the center of the first ratchet. Pulleys are fixedly connected to both the central shaft and the output shaft of the drive motor. A transmission belt is fitted onto the two pulleys. A second ratchet and a third ratchet are rotatably connected to the reciprocating bracket, and the second and third ratchets are located on both sides of the first ratchet.

[0010] As a preferred embodiment, the bottom of the skateboard is provided with two parallel I-beam guide rails, and two rows of first rollers are rotatably connected to both sides of the mounting base. The first rollers are slidably connected to the I-beam guide rails, and two rows of second rollers are rotatably connected to both sides of the support plate.

[0011] As a preferred embodiment, the top of the skateboard is fixedly connected to two first limiting blocks, and the bottom of the bearing plate is fixedly connected to a second limiting block, with the second limiting block located between the two first limiting blocks.

[0012] As a preferred embodiment, the support platform is provided with two support brackets, which are located on both sides of the reciprocating mechanism, and multiple third rollers are rotatably connected to the support brackets.

[0013] The beneficial effects of the port transfer equipment with an anti-slip structure disclosed in this utility model are:

[0014] The traveling device moves the equipment to the loading and unloading areas. When the equipment enters the loading area, the reciprocating mechanism drives the support plate to slide out of the equipment, allowing the external loading device to place the storage bins on the support plate. The reciprocating mechanism then drives the support plate to slide back into the equipment, bringing the storage bins into the clamping area. Depending on the height of the storage bins, the screw mechanism drives the clamping mechanism to slide to the middle position of the storage bins. The clamping motor drives the second gear and two third gears to rotate through the first gear, causing the contact wheels of the two clamping mechanisms to contact and clamp the storage bins. This ensures that the storage bins are firmly contained within the clamping area during equipment movement, preventing them from slipping off the equipment. When the equipment enters the loading area, the reciprocating mechanism drives the support plate to slide the storage bins out of the equipment, allowing the external unloading device to remove the storage bins from the equipment.

[0027] In this embodiment, the preferred traveling device 1 is an AGV vehicle. The traveling device 1 drives the equipment to travel back and forth between the loading area and the unloading area. The frame 2 is fixedly connected to the top of the traveling device 1, and the frame 2 is provided with a support platform 21.

[0028] Please refer to Figures 1-6 .

[0029] A reciprocating mechanism 3 is provided on the frame 2, and a support plate 36 is slidably connected to the reciprocating mechanism 3. The reciprocating mechanism 3 includes a mounting base 31, a sliding plate 35, and a drive assembly. The mounting base 31 is placed on the support platform 21, and two rows of first rollers 311 are rotatably connected to both sides of the mounting base 31. The drive assembly is connected to the mounting base 31. The drive assembly includes a reciprocating bracket 32 ​​and a drive motor 34. A first ratchet 321 is rotatably connected to the reciprocating bracket 32. A central shaft extends from the center of the first ratchet 321. Pulleys are fixedly connected to both the central shaft and the output shaft of the drive motor 34. A transmission belt 341 is sleeved on the two pulleys. The drive motor 34 drives the central shaft and the first ratchet 321 to rotate through the transmission belt 341. A second ratchet 322 and a third ratchet 323 are rotatably connected to the reciprocating bracket 32. The second ratchet 322 and the third ratchet 323 are located on both sides of the first ratchet 321, respectively.

[0030] Furthermore, the bottom of the slide plate 35 is provided with two parallel I-beam guide rails 351. The slide plate 35 is slidably connected to the first roller 311 of the mounting base 31 through the I-beam guide rails 351. The mounting base 31 is located between the two I-beam guide rails 351. The two ends of the slide plate 35 are respectively rotatably connected with a fourth ratchet 353 and a fifth ratchet 354. The top of the slide plate 35 is fixedly connected with two first limit blocks 352, and the two first limit blocks 352 are spaced a certain distance apart.

[0031] Furthermore, two rows of second rollers 361 are rotatably connected to both sides of the support plate 36. The support plate 36 is slidably connected to the I-beam guide rail 351 of the slide plate 35 via the second rollers 361, and the slide plate 35 is located between the two rows of second rollers 361. A second limiting block 362 is fixedly connected to the bottom of the support plate 36, and the second limiting block 362 is located between two first limiting blocks 352. A chain 37 is sleeved on the drive assembly, and the chain 37 is sleeved on the first ratchet 321, the second ratchet 322, and the third ratchet 322. On the outer sides of the first ratchet 321, second ratchet 322, third ratchet 323, fourth ratchet 353 and fifth ratchet 354, the first ratchet 321, second ratchet 322, third ratchet 323, fourth ratchet 353 and fifth ratchet 354 are all connected to the chain 37. The first ratchet 321, second ratchet 322, third ratchet 323, fourth ratchet 353 and fifth ratchet 354 unfold the chain 37 so that the chain 37 can be coiled on the slide plate 35 and the mounting base 31. Both ends of the chain 37 are fixedly connected to the support plate 36.

[0032] Please refer to Figure 1 and Figure 2 .

[0033] The support platform 21 is provided with two support brackets 22, which are located on both sides of the reciprocating mechanism 3. The sliding path of the support brackets 22 is parallel to that of the support plate 36. Multiple third rollers 221 are rotatably connected to the support brackets 22. When the support plate 36 is retracted into the support platform 21, the bottom of the storage barrel contacts the outer side of the third roller 221 and pushes it to rotate. The rotation of the third roller 221 can reduce the reaction force on the storage barrel when it is retracted into the frame 2. The support brackets 22 and the third rollers 221 can assist in supporting the storage barrel and share the downward pressure applied by the storage barrel to the support plate 36 and the reciprocating mechanism 3.

[0034] Please refer to Figure 1 and Figures 7-9 .

[0035] Two lead screw mechanisms 4 are respectively connected to both sides of the frame 2. The lead screw mechanism 4 includes a lead screw motor 41, a ball screw 42, and two guide rods 43. The two lead screw motors 41 are fixedly connected to both sides of the frame 2. One end of the ball screw 42 is rotatably connected to the frame 2, and the other end of the ball screw 42 is fixedly connected to the output shaft of the lead screw motor 41. The two ball screws 42 are parallel to each other and perpendicular to the support platform 21. A ball bearing seat is slidably connected to the ball screw 42. Both ends of the guide rods 43 are fixedly connected to the frame 2. The two guide rods 43 are located on both sides of the ball screw 42 and are parallel to each other. The lead screw motor 41 drives the ball screw 42 to rotate, so that the ball screw 42 drives the ball bearing seat to slide up or down on the ball screw 42.

[0036] A clamping mechanism 5 is slidably connected to the lead screw mechanism 4. The two clamping mechanisms 5 are symmetrical and opposite to each other, and a clamping area is formed between the clamping mechanisms 5. The bearing plate 36 is located below the clamping area.

[0037] The clamping mechanism 5 includes a connecting seat 51 and two symmetrical first clamping arms 52. The connecting seat 51 is fixedly connected to the ball bearing seat, and the connecting seat 51 is slidably connected to the ball screw 42 through the ball bearing seat. The connecting seat 51 is also slidably connected to the guide rod 43. A first gear 511 and a second gear 512 are rotatably connected to the connecting seat 51. The first gear 511 and the second gear 512 are engaged and connected. A clamping motor 513 is provided on the connecting seat 51. The output shaft of the clamping motor 513 is connected to the first gear 511, and the clamping motor 513 drives the first gear 511 to rotate.

[0038] Furthermore, the first clamping arm 52 is rotatably connected to the connecting seat 51. The first clamping arm 52 is provided with a third gear 521, and the two third gears 521 are respectively connected to the first gear 511 and the second gear 512. The first clamping arm 52 is rotatably connected to the second clamping arm 53, and the first clamping arm 52 is provided with a contact wheel 531. In this embodiment, the contact wheel 531 is preferably made of rubber to reduce the squeezing force when the contact wheel 531 touches the storage barrel. The contact wheel 531 is rotatably connected to the second clamping arm 53 and is close to the clamping area. The second clamping arm 53 is rotatably connected to the connecting rod 532, and the connecting rod 532 is rotatably connected to the connecting seat 51.

[0039] Please refer to Figures 1-9 .

[0040] When the traveling device 1 drives the equipment into the loading area, the drive motor 34 drives the first ratchet 321 to rotate. The first ratchet 321 drives the chain 37 to move. The chain 37 pulls the bearing plate 36 to slide on the slide plate 35 and extend it out of the bearing platform 21. The second limit block 362 on the bearing plate 36 touches one of the second limit blocks 362. The bearing plate 36 pulls the slide plate 35 to slide on the mounting base 31, increasing the length of the bearing plate 36 extending on the equipment. The slide plate 35 also increases the contact area between the bearing plate 36 and the mounting base 31, improving the bearing plate 36's ability to bear weight when extending out of the equipment. The external loading device places the storage barrel on the bearing plate 36. The drive motor 34 drives the first ratchet 321 to rotate. The first ratchet 321 drives the chain 37 to move. The chain 37 pulls the bearing plate 36 to slide on the slide plate 35 and retract into the bearing platform 21. The bearing plate 36 retracts the storage barrel placed on top into the frame 2.

[0041] As the storage barrel is retracted into the frame 2, it is also located within the clamping area. Depending on the height of the storage barrel, the screw mechanism 4 drives the clamping mechanism 5 to rise or fall to the middle of the storage barrel. The clamping motor 513 sequentially drives the first gear 511, the second gear 512, and the two third gears 521 to rotate, causing the two first clamping arms 52 to rotate on the connecting seat 51. The connecting rod 532 pulls the second clamping arm 53 to rotate on the first clamping arm 52, ensuring that the contact wheel 531 always faces the clamping area and that the contact wheels 531 of the two clamping mechanisms 5 abut against the outside of the storage barrel, thereby limiting the storage barrel within the clamping area and preventing the storage barrel from slipping off the equipment when it is moved.

[0042] When the traveling device 1 drives the equipment into the unloading area, the clamping motor 513 sequentially drives the first gear 511, the second gear 512 and the two third gears 521 to rotate, so that the two first clamping arms 52 rotate on the connecting seat 51, so that the contact wheel 531 moves away from the storage barrel, and releases the clamping mechanism 5 from the limit on the storage barrel.

[0043] The drive motor 34 drives the first ratchet 321 to rotate, which in turn drives the chain 37 to move. The chain 37 pulls the support plate 36 to slide on the slide plate 35 and extend it out of the support platform 21, allowing the external unloading device to remove the storage barrels from the support plate 36, thus completing the transfer of the storage barrels. The drive motor 34 drives the first ratchet 321 to rotate, which in turn drives the chain 37 to move. The chain 37 pulls the support plate 36 to slide on the slide plate 35 and retract it into the support platform 21.

[0044] This utility model provides a port transfer device with an anti-slip structure. A traveling device moves the device to the loading and unloading areas. When the device enters the loading area, a reciprocating mechanism drives a support plate to slide out of the device, allowing an external loading device to place storage containers on the support plate. The reciprocating mechanism then drives the support plate to slide back into the device, holding the storage containers in the clamping area. Based on the height of the storage containers, a screw mechanism drives the clamping mechanism to slide to the middle position of the containers. The clamping motor, through a first gear, drives a second gear and two third gears to rotate, causing the contact wheels of the two clamping mechanisms to contact and clamp the storage containers. This ensures that the containers are firmly contained within the clamping area during movement, preventing them from slipping off the device. When the device enters the loading area, the reciprocating mechanism drives the support plate to slide the storage containers out of the device, allowing an external unloading device to remove the containers from the device.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
