Description

Technical Field

[0001] The present invention relates to the technical field of marine ship cargo transportation, and in particular to an automated cargo transportation device suitable for marine ship transportation. Background Art

[0002] Shipping is a mode of transportation that uses ships to transport passengers or goods by water. It can be divided into coastal transportation and ocean transportation. Usually, the maritime transportation between domestic coastal ports is called coastal transportation, while the maritime transportation between domestic ports and foreign ports or between foreign ports is called ocean transportation. Marine cargo ships can be divided into the following categories according to the types of goods they carry and the methods of loading and unloading: dry cargo ships, which are divided into general cargo ships and bulk cargo ships; general cargo ships are mainly used to carry various types of general cargo, and new general cargo ships are mostly designed as multi-purpose ships with strong adaptability to the types of cargo; bulk cargo ships are specially used to carry various bulk cargoes, and can be divided into coal carriers, ore carriers, bulk grain carriers, wood carriers and bulk cement carriers, etc.; Liquid cargo ship, a ship carrying various liquid cargoes, mainly oil tankers, liquid chemical tankers, liquefied gas tankers; in addition, there are also dual-purpose ships that can carry both liquid cargoes and dry bulk cargoes; Container ship, a cargo ship that uses standard containers as cargo units; this type of ship has high speed, sails on fixed routes, and uses special port equipment for rapid loading and unloading; There are also ro-ro ships and barges. When transporting general cargo, considering the packaging of the cargo, cranes are used to transport the packaged cargo. Operators are required to accompany the operation on the ship and continuously perform lifting and fixing. The overall risk is high. At the same time, the number of single liftings is limited, and most of them are intermittent clamping operations, which reduces the efficiency of the entire ship's cargo transportation; To this end, we propose an automated cargo conveying device suitable for marine vessel transportation. Summary of the invention

[0003] The object of the present invention is to provide an automated cargo conveying device suitable for marine ship transportation to solve the problems raised in the above background technology; To achieve the above-mentioned object, the present invention provides the following technical solution: an automated cargo conveying device suitable for marine ship transportation, comprising a transmission seat and a guide frame, the top of the transmission seat is fixed with the guide frame by bolts, the bottom of the guide frame is evenly slidably connected with a movable chuck, one side of the movable chuck is provided with a limiting groove 1, and the other side of the movable chuck is provided with a limiting groove 2, and the bottom of the movable chuck is movably connected with a limiting cylinder through a bearing; The two sides of the limit cylinder are symmetrically fixedly connected with tooth columns, and the bottom of the tooth column is slidably connected with an adaptive clamping plate assembly, and the adaptive clamping plate assembly includes a buckle plate, a clamping block, a transmission box and a clamping plate. The bottom of the tooth column is slidably connected with a buckle plate, and the top of the buckle plate is fixed with a clamping block by bolts. Gear sleeves are symmetrically slidably connected on the tracks on both sides of the buckle plate, and a plate clamp is fixed to the bottom of the gear sleeve by welding, and a transmission box is fixed with bolts on the top of the buckle plate and located on the tooth column side, and a gear shaft is movably connected in the transmission box, and the gear at one end of the gear shaft is meshed with the gear sleeve correspondingly, and the gear on the other side of the gear shaft is meshed with the gear column correspondingly.

[0004] Furthermore, a second blocking cover is fixed to the bottom inner wall of the limiting cylinder by bolts, and a first blocking cover is fixed to the top inner wall of the limiting cylinder by bolts. A lock column is slidably connected inside the second blocking cover, and a protrusion on the outer wall of the lock column abuts against the second blocking cover. One end of the lock column passes through the limiting cylinder and abuts against the clamping block.

[0005] Furthermore, a locking frame is fixed to the guide frame by bolts, a material storage plate is slidably connected to the locking frame, and a threaded sleeve is fixed to the top of the material storage plate by bolts.

[0006] Furthermore, a driving motor 1 is fixed to the top of the guide frame by bolts, a threaded rod is fixed to the output end of the driving motor 1, and one end of the threaded rod is threadedly connected to the threaded sleeve.

[0007] Furthermore, a belt pulley is symmetrically and movably connected to the bottom of the guide frame, and a rotating sleeve is movably connected to the guide frame and sleeved on the outer wall of the threaded rod. One of the belt pulleys is fixed to the rotating sleeve, and a second drive motor is fixed to the top of the guide frame by bolts. The second drive motor is meshed and connected with a gear sleeved on the rotating sleeve through a gear.

[0008] Furthermore, a transmission belt is sleeved and installed on the two belt pulleys, and the outer wall of the transmission belt is evenly fixedly connected with a limiting block, and the upper limit block of the transmission belt is correspondingly engaged with the limiting groove.

[0009] Furthermore, the top of the guide frame is evenly and movably connected to an electric push rod through a bearing, and the two sides of the top of the guide frame are symmetrically and movably connected to a transmission shaft. The outer wall of the transmission shaft is evenly sleeved and fixed with a clamping column, and the output end of the electric push rod is movably connected to the transmission shaft through a connecting rod.

[0010] The automated cargo delivery method suitable for marine vessel transportation is: Feed alternately, rotate the transmission seat, rotate the guide frame with the storage board side to the ship side, drive motor 1 to drive the transmission belt to rotate, and drive motor 2 to drive the entire storage board to move downward, at this time, move the packaged ship cargo to the storage board; Whenever the movable chuck moves to the top of the material storage plate, the lifted material storage plate moves the goods to the side of the plate clamp, abuts against the plate clamp and drives the entire buckle plate to rise. During the lifting process of the lock column at the bottom of the limit cylinder, it contacts the baffle cover and automatically rotates 90 degrees. The goods continue to push the plate clamp upward, causing the plate clamps on both sides to unfold and come to both sides of the goods. As the material storage plate descends, the plate clamps on both sides of the goods begin to close, completing the clamping of both sides of the goods, and rotating through the transmission belt to start driving the goods to move to the material storage area. When the plate clamps carrying the goods touch the sloped conveyor belt surface, the goods and the plate clamps are lifted up on the cut surface at the same time, and the plate clamps on both sides begin to expand and send the goods to the conveyor belt, completing the automatic transportation of the ship's goods to the port end.

[0011] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, on the basis of the original single-side driven lifting and conveying, a guide frame is installed, and a plurality of sets of movable chucks are arranged to carry out cyclic conveying, so as to improve the overall ship cargo transportation efficiency. At the same time, the adaptive clamping plate assembly arranged on the movable chuck cooperates with the material storage plate that lifts up and down to make up for the height difference between the ship and the port side, and can complete the clamping of the cargo by itself. Compared with the power-driven clamping, the overall power consumption of the cargo conveying equipment is reduced. At the same time, when the plate clamp moves on the cargo and the installed conveyor belt side, a height limiting mechanism is set to adjust the position of the buckle plate on the tooth column, so that the self-feeding and unloading of the cargo on the plate clamp side and the subsequent automatic stacking can be realized, which provides convenience for subsequent loading.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0015] See also Figure 1-6 , the present invention provides a technical solution: Example 1: Considering the bulk material transportation during the transportation of small ships, the grab bucket on the port side is used in conjunction with the crane to pick up and place the materials one by one. This involves the transportation of packaged materials, similar to cement. The bagged materials are also transported in batches by the crane. The overall transportation efficiency is low, and operators are required to accompany the whole process and fix them with straps. The material transportation risk is high. For this reason Figure 1 and Figure 2 As shown, the transmission seat 1 is installed on the transport port side, similar to the crane structure, and the guide frame 2 is installed on the top of the transmission seat 1. Due to the height difference between the ship silo and the port, a movable storage plate 14 is arranged on the side of the guide frame 2 to facilitate the transfer of ship materials. Similarly, since the guide frame 2 adopts a one-by-one cyclic feeding, there is no need to carry out combined packaging of materials on the ship. Bulk materials can be automatically stacked on the conveyor belt on the port side with the active chuck 10 for cyclic transportation, thereby improving the efficiency of automated cargo transportation for ship transportation; During specific operation, a movable chuck 10 is evenly arranged at the bottom of the guide frame 2, and the limiting wheel at the top of the movable chuck 10 is clamped with the inner raceway of the guide frame 2, which facilitates the driving of the movable chuck 10. A transmission belt 8 is installed on the belt pulley 7 at the bottom of the guide frame 2, and a limiting block 9 is evenly fixed on the outer side of the transmission belt 8. Figure 3As shown, a single limit block 9 is engaged with an upper limit groove 11 of a single movable chuck 10, and the entire movable chuck moves synchronously with the rotation of the transmission belt 8. For the drive of the belt pulley 7, a driving motor 2 5 is installed on the top of the guide frame 2, and a rotating sleeve 6 is fixedly connected to the middle of the belt pulley 7. The driving motor 2 5 drives the rotating sleeve 6 to rotate through the gear to control the circulation of the entire belt pulley 7. At the same time, a limiting groove 12 is provided on the other side of the movable chuck 10 to prevent the adaptive clamping plate assembly 21 at the bottom from automatically sliding when the entire guide frame 2 is no longer in use, causing the transmission mechanism to be unable to identify the specific placement position later. For this reason, when the automated cargo conveying device for ship transportation is not in use, the movable chuck 10 needs to be limited, and electric push rods 22 are evenly arranged on the top of the entire guide frame 2. Transmission shafts 23 are symmetrically and movably connected on both sides of the guide frame 2, and a clamping column 24 is fixedly mounted on the transmission shaft 23. The end of the electric push rod 22 is movably connected to the transmission shaft 23 by a connecting rod, and the transmission shaft 23 is pushed to rotate by the electric push rod 22, thereby driving the end of the clamping column 24 to abut against the upper limiting groove 12 of the movable chuck 10, thereby completing the constraint of the entire movable chuck 10.

[0016] Embodiment 2: Considering that the automated cargo transportation of ship transportation requires cargo clamping, a lock frame 13 is fixedly connected to the top of the guide frame 2, such as Figure 4 As shown, a material storage plate 14 is slidably connected to the inner side of the lock frame 13. The material storage plate 14 that can move up and down is provided to receive the cargo on the ship side, and the movable chuck 10 that circulates is used to transfer the cargo on the material storage plate 14, thereby avoiding the height difference between the ship and the port, which causes the cargo to be unable to be lifted and transported normally; As for the driving of the entire storage plate, a driving motor 3 is installed on the top of the guide frame 2, and the threaded rod 4 fixed at its end is connected to the threaded sleeve 15 fixed on the storage plate. The driving motor 3 drives the threaded rod 4 to rotate, so that the entire storage plate can slide on the lock frame 13; At the same time, the goods on the storage board are automatically grabbed. Whenever the movable chuck 10 carrying the adaptive clamping plate assembly 21 rotates to the top of the storage board with the transmission belt 8, the storage board carrying the goods is automatically lifted, and the goods on the storage board gradually contact the board clamp 216. Figure 5 As shown, the plate clamp 216 is located on the tooth sleeve 215 at the top of the pinch plate 211, and the tooth sleeve 215 is slidably connected due to the groove on the pinch plate 211, and the entire pinch plate 211 is slidably connected to the limiting cylinder 16 at the bottom of the movable chuck 10, and is connected through the tooth column 20; The goods first contact the plate clamp 216 and drive the entire plate clamp 211 connected to the plate clamp 216 to move upward synchronously. A transmission box 213 is also fixedly arranged on the top of the plate clamp 211. A gear shaft 214 is movably connected in the transmission box 213. A gear is sleeved on the gear shaft 214 in the transmission box 213 and meshed with the gear column 20. A fixed gear is sleeved on the end of the gear shaft 214 outside the transmission box 213 and meshed with the gear sleeve 215. As the plate clamp 211 rises, the gear in the transmission box 213 starts to rotate, causing the gear shaft 214 to start driving the gear sleeves 215 on both sides to slide on the plate clamp 211, causing the distance between the two plate clamps 216 at the bottom of the gear sleeve 215 to gradually expand, and finally causing the goods on the storage board to start to move to the middle of the plate clamp 216 alone, and at this time, the plate clamp 216 starts to move downward without the push of the goods. like Figure 6 As shown, a blocking cover 17 and a blocking cover 2 18 are fixedly connected in the entire limiting cylinder 16, and the opposite surfaces of the blocking cover 17 and the blocking cover 2 18 are provided with staggered cutouts, and a lock column 19 is slidably connected to the blocking cover 2 18, and the protrusion on the outer wall of the lock column 19 abuts against the cutout on the blocking cover 2 18, so as to be fixed to the blocking cover 2 18, and at the same time, the lock column 19 is located on the outer side of the limiting cylinder 16 and abuts against the clamping block 212 fixedly set on the buckle plate 211. Therefore, when the entire buckle plate 211 rises with the goods, the clamping block 212 synchronously drives the lock column 19 to slide in the limiting cylinder 16, and when the protrusion on the lock column 19 contacts the cut surface of the blocking cover 17, it drives the entire lock column 19 to move. 90 degree rotation, at this time, the end of the lock column 19 rotates 90 degrees and begins to separate from the entire clamp block 212, returning to the entire plate clamp 216 and descending on the cargo side. The pinch plate 211 is no longer limited by the clamp block 212 and the lock column 19, and the descending distance increases. As the entire pinch plate 211 slides downward, the gear shaft 214 rotates at this time to drive the gear sleeve 215 and the side plate clamps 216 to move toward each other, thereby clamping the cargo on both sides during the ascending process. At this time, only the storage plate needs to move downward to leave the stacked cargo on the plate clamp 216, thus realizing automatic material removal of the cargo. Compared with the cargo clamping achieved by the power mechanism, it is easily affected by electricity and causes the clamp arm to fail, and the overall power consumption increases; The circulating movable chuck 10 will come to the top of the storage plate and start to clamp the ship. After a period of transportation on the guide frame 2, the clamped goods need to be unloaded. For this purpose, a conveyor belt can be set in the unloading area. At the same time, the transmission belt 8 adopts a section lifting type with a certain slope, such as Figure 6As shown, at this time, the goods located on the inner side of the plate clamp 216 begin to move toward the side of the transmission belt 8. As the height of the entire conveyor belt continues to increase, the sliding plate clamp 216 begins to move upward, causing the gear shaft 214 to drive the gear sleeve 215 to rotate in the opposite direction, thereby increasing the distance between the plate clamps 216 on both sides, and finally leaving the goods on the conveyor belt. At this time, the locking column 19 will also be driven to rise during the rising process of the buckle plate 211, and it will contact the baffle 17 again to realize its own 90-degree rotation, thereby completing the locking of the entire buckle plate 211, facilitating the subsequent continuous clamping operation.

[0017] The working principle of the present invention is as follows: the guide frame 2 with the material storage plate 14 is rotated to the ship side by the rotation of the transmission seat 1, the driving motor 1 3 drives the transmission belt 8 to rotate, and the driving motor 2 5 drives the entire material storage plate 14 to move downward, and at this time, the packaged ship cargo is moved to the material storage plate 14; Whenever the movable chuck 10 moves to the top of the material storage plate 14, the lifted material storage plate 14 moves the goods to the side of the plate clamp 216, abuts against the plate clamp 216 and drives the entire buckle plate 211 to rise. During the lifting process, the lock column 19 at the bottom of the limit cylinder 16 contacts the baffle 17 and automatically rotates 90 degrees. During the continuous pushing of the plate clamp 216 by the goods, the plate clamps 216 on both sides are unfolded, and then come to the two sides of the goods. With the descending of the material storage plate 14, the plate clamps 216 on both sides of the goods begin to close, completing the clamping of the two sides of the goods, and rotating through the transmission belt 8, start to drive the goods to move to the material storage area; When the plate clamp 216 carrying the goods contacts the sloped conveyor belt surface, the goods and the plate clamp 216 are lifted up on the cut surface at the same time, and the plate clamps 216 on both sides begin to expand and send the goods to the conveyor belt, completing the automatic transportation of the ship's goods to the port end.
