Description

Technical Field

[0001] The present invention relates to the technical field of bulk carrier unloading equipment, and in particular to an automatic unloading equipment for bulk carriers. Background Art

[0002] Bulk carriers are cargo ships that specialize in transporting unpackaged bulk cargo, such as sand, gravel, coal and other goods. They need to unload bulk cargo after entering the port. In order to improve the unloading efficiency of the ship, dedicated ship unloading equipment is often used. Through background control, the automatic unloading equipment can unload in an orderly manner according to the size of the ship.

[0003] The common bulk carrier loading and unloading equipment is mostly controlled by the backstage staff when in use. The unloading bucket is installed with the corresponding gantry crane so that the unloading bucket can grab the cargo and carry out lifting and unloading. The common bulk carrier loading and unloading equipment has good convenience when in use, but there are still some problems:

[0004] When the common bulk carrier's loading and unloading equipment is in use, two sets of buckets are pushed by a hydraulic press to grab the bulk cargo, and the gantry crane controls the bucket to transfer and unload. In this process, due to the hinged flipping of the two sets of buckets, the connection may become loose due to wear, resulting in a large gap between the two sets of buckets. At this time, the bulk cargo is easy to leak from the bucket and fall from a high altitude, which poses a safety hazard to the bulk carrier's loading and unloading equipment. Summary of the invention

[0005] The object of the present invention is to provide an automatic loading and unloading device for bulk carriers, so as to solve the defect that the existing automatic loading and unloading device for bulk carriers is easy to be loosened due to wear and tear, resulting in leakage of cargo from bucket gaps.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an automatic loading and unloading device for bulk carriers, comprising a connecting seat and a first bucket frame, the bottom end of the connecting seat is fixedly connected to a connecting frame, the tops on both sides of the connecting frame are hinged with hydraulic push-pull rods, the bottoms at both ends of the connecting frame are hinged with the first bucket frame, the middle position of the bottom end of the connecting frame is fixedly connected with a first articulated frame, one side of the first bucket frame is provided with a second bucket frame, and both ends of the first bucket frame are provided with auxiliary structures, the auxiliary structures include a limit frame, a limit groove, a rotating plate, a linkage rod, an insertion rod, a guide groove, a push block and a first spring, the limit frame is fixedly connected to one end of the second bucket frame, the first bucket frame and the top ends of the inner side walls of the second bucket frame are fixedly connected with a second articulated frame, and cleaning structures are fixedly connected to both sides of the first articulated frame.

[0007] When in use, the connecting seat is connected to the corresponding gantry crane through chains, ropes and other connecting objects, and then the staff operates the gantry crane to move the unloading equipment into the bulk carrier's cabin, and then starts the hydraulic push-pull rod to retract its bottom. At this time, since the first bucket frame, the second bucket frame and the bottom of both sides of the connecting frame are hinged structures, as the bottom of the hydraulic push-pull rod retracts, the first bucket frame and the second bucket frame are gradually unfolded and inserted into the bulk cargo area in the cabin under the control of the gantry crane, and then the bottom of the hydraulic push-pull rod extends and pushes the first bucket frame and the second bucket frame to close and dig a large amount of bulk cargo, and then moves the excavated bulk cargo to the designated storage place under the control of the gantry crane, and unfolds the first bucket frame and the second bucket frame to make the bulk cargo fall, and repeats the above operations to complete the automatic unloading operation of bulk cargo in the bulk carrier.

[0008] Preferably, a limiting groove is provided on one side of the top of the limiting frame, a rotating plate is rotatably connected to one side of one end of the first bucket frame, linkage rods are slidably connected to the interior of both ends of one side of the first bucket frame, an insertion rod is rotatably connected to the top of one end of the rotating plate, guide grooves are provided inside one side of both ends of the first bucket frame, a push block is fixedly connected to one end of the linkage rod, and a first spring is fixedly connected to one side of the linkage rod. When the first bucket frame and the second bucket frame are closed under the push of the hydraulic push-pull rod, the second bucket frame will squeeze the linkage rod to retract it, causing the insertion rod to be stuck in the limiting groove to form a self-locking.

[0009] Preferably, the rotating plate and the first bucket frame are in a rotating structure, and the guide groove and the push block are in a sliding structure, so that the rotating plate can rotate stably.

[0010] Preferably, the linkage rods are symmetrically distributed at two ends of one side of the first bucket frame, and the rotating plate and the inserting rod are in a rotating structure.

[0011] Preferably, the linkage rod is perpendicular to one side of the first bucket frame.

[0012] Preferably, a torsion spring is sleeved at the connection between the rotating plate and the first bucket frame, so that the rotating plate can be kept stable.

[0013] Preferably, the cleaning structure includes a sleeve, a connecting plate, a support frame, a brush plate and a second spring, the sleeve is fixedly connected to both sides of the first hinged frame, one side of the interior of the sleeve is sleeved with a connecting plate, one side of the connecting plate is fixedly connected to the support frame, one side of the support frame is fixedly connected to the brush plate, and one side of the interior of the sleeve is fixedly connected to the second spring. As the first bucket frame and the second bucket frame are unfolded, closed and flipped, the brush plate will gradually scrape off the adsorbed residues on the inner walls of the first bucket frame and the second bucket frame.

[0014] Preferably, the sleeve and the connecting plate are in a sliding structure, and the connecting plate is perpendicular to the supporting frame.

[0015] Preferably, the connecting plate and the second spring are in an elastic connection structure, so that the brush plate can be closely attached to the inner wall of the bucket.

[0016] The present invention provides an automatic loading and unloading device for bulk carriers, which has the advantages that: by providing an auxiliary structure, when the first bucket frame and the second bucket frame are closed under the push of the hydraulic push-pull rod, the second bucket frame will squeeze the linkage rod to retract it, and make the push block slide along the guide groove and push the rotating plate to rotate, so that the insertion rod is stuck in the limiting groove to form a self-locking, so that the closure of the first bucket frame and the second bucket frame maintains good stability, thereby achieving the goal of improving the tightness of the bucket docking.

[0028] Refer to the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6When the automatic unloading equipment is in use, the connecting seat 1 is connected to the corresponding gantry crane by connecting objects such as chains and ropes, and then the staff operates the gantry crane to move the unloading equipment into the bulk carrier's cabin, and then starts the hydraulic push-pull rod 3 to retract its bottom. At this time, since the first bucket frame 4, the second bucket frame 5 and the bottom of both sides of the connecting frame 2 are hinged structures, as the bottom of the hydraulic push-pull rod 3 retracts, the first bucket frame 4 and the second bucket frame 5 are gradually unfolded and inserted into the bulk cargo in the cabin under the control of the gantry crane, and then the bottom of the hydraulic push-pull rod 3 extends and pushes the first bucket frame 4 and the second bucket frame 5 to close and dig a large amount of bulk cargo, and then moves the excavated bulk cargo to the designated storage place under the control of the gantry crane, and unfolds the first bucket frame 4 and the second bucket frame 5 to make the bulk cargo fall, and repeats the above operations to complete the automatic unloading operation of the bulk cargo in the bulk carrier. In this process, since the first bucket frame 4 and the second bucket frame 5 need to be extended and retracted by the hydraulic push-pull rod 3 The first bucket frame 4 and the second bucket frame 5 are retracted to complete the digging and unloading of the bulk cargo. Since the connection between the first bucket frame 4 and the second bucket frame 5 is prone to certain wear, a certain gap is prone to appear between the first bucket frame 4 and the second bucket frame 5 after they are closed and flipped. The gap is increasingly larger as the lock wear increases. Moreover, since the unloading equipment is at a high altitude, if the bulk cargo falls from the gap, a safety accident is likely to occur. For this reason, the linkage rod 604 is slidably connected to the inside of both ends of one side of the first bucket frame 4. When the first bucket frame 4 and the second bucket frame 5 are closed under the push of the hydraulic push-pull rod 3, the second bucket frame 5 will squeeze the linkage rod 604 to retract it, and make the push block 607 slide along the guide groove 606. At this time, the sliding of the push block 607 will push the rotating plate 603 to rotate, prompting the insertion rod 605 to be stuck in the limiting groove 602 to form a self-locking, so that the closure of the first bucket frame 4 and the second bucket frame 5 maintains a good stability, and avoids the gap between the first bucket frame 4 and the second bucket frame 5 from increasing due to heavy cargo.

[0029] A cleaning structure 9 is fixedly connected to both sides of the first articulated frame 7, and the cleaning structure 9 includes a sleeve 901, a connecting plate 902, a support frame 903, a brush plate 904 and a second spring 905. The sleeve 901 is fixedly connected to both sides of the first articulated frame 7, a connecting plate 902 is sleeved on one side inside the sleeve 901, a support frame 903 is fixedly connected to one side of the connecting plate 902, a brush plate 904 is fixedly connected to one side of the support frame 903, and a second spring 905 is fixedly connected to one side inside the sleeve 901. The sleeve 901 and the connecting plate 902 are in a sliding structure, the connecting plate 902 is perpendicular to the support frame 903, and the connecting plate 902 and the second spring 905 are in an elastic connection structure.

[0030] Refer to the attached Figure 1 , Figure 7 and Figure 8When the unloading equipment is in use, a large amount of residue is easily adsorbed on the inner wall of the bucket when unloading bulk goods such as coal, sand and gravel. When the adsorption force of the bulk cargo residue is too large and is not scraped off in time, some of the residue is easy to condense into a ball and reduce the unloading space of the bucket, thereby reducing the unloading efficiency of the unloading equipment. Therefore, after the bucket is used, it is often necessary to manually clean it and scrape off the adsorbed bulk cargo residue. In order to improve its cleaning efficiency, a connecting sleeve 901 is fixed on the outer side of the first articulated frame 7, and under the elastic force of the second spring 905, the limiting groove 602 pushes the support frame 903, and then the brush plate 904 is close to the inner wall of the bucket. As the first bucket frame 4 and the second bucket frame 5 are unfolded and closed, the brush plate 904 will gradually scrape off the adsorbed residue on the inner wall of the first bucket frame 4 and the second bucket frame 5, so that after the unloading equipment is used, there is no need to spend a lot of manpower and material resources for cleaning.
