Description

Technical Field

[0001] This invention relates to the field of loading and unloading equipment technology, specifically a port bulk material loading and unloading barge. Background Technology

[0002] In the process of loading and unloading cargo at port terminals, when existing port or terminal facilities are insufficient or have limited capacity for shore-based loading and unloading, or when large bulk carriers cannot be directly berthed, barges are often used to achieve efficient transfer of cargo between ships and shore, and between ships.

[0003] When existing ports or wharves lack sufficient shore-based loading and unloading equipment or cannot directly berth large bulk carriers; and in inland waterways such as the Yangtze River and Pearl River, large ocean-going vessels cannot directly reach inland ports due to insufficient water depth; in all these scenarios, pontoons are needed to transfer materials to achieve material transshipment.

[0004] In most existing pontoons, the loading and unloading of materials is carried out using lifting equipment, which is a loading-then-unloading method. This method is inefficient and has poor applicability. For some complex operating environments, it cannot effectively get rid of the dependence on fixed docks. At the same time, due to the different heights of cargo ships, the material conveying height cannot be adjusted in a timely and effective manner during the transfer process, resulting in instability and poor flexibility in material conveying. In addition, dust will fly at high altitudes during the conveying of some powdery and granular materials, and adhesive substances will also adhere to the equipment, affecting the subsequent material conveying.

[0005] Therefore, the present invention provides a port bulk material loading and unloading barge to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a port bulk material loading and unloading barge, which is effectively applicable to different operating environments, can flexibly transfer materials to achieve simultaneous loading and transportation, improves transfer efficiency, and does not rely on a fixed dock, can dock in any water area such as anchorage, shoal, and temporary operation point, solving the problem of difficult operation in areas without docks or with insufficient dock facilities.

[0007] The present invention includes a barge, a clamshell grab bucket, and a conveying device. A rotating base is fixedly connected to the barge, and the clamshell grab bucket is rotatably connected to the rotating base, enabling the clamshell grab bucket to rotate in a circumferential direction to grab materials. A rotating disk is connected to the other end of the barge, and the rotating disk is connected to a drive structure located inside the barge. The conveying device is fixedly connected to the rotating disk, enabling the conveying device to rotate around the barge and transfer materials to a cargo ship. The conveying equipment includes a rotating base fixedly connected to the rotating disk, a primary conveyor frame fixedly connected to the rotating base, a secondary conveyor frame connected to the rotating base at the end of the primary conveyor frame away from the grab bucket, and drive rollers rotatably connected to the ends of both the primary and secondary conveyor frames. The primary, secondary, and drive rollers are all connected to a conveyor belt, which is U-shaped to prevent material from slipping during conveying. One of the drive rollers is connected to an external motor. A feeding hopper is fixedly connected to the upper end of the rotating base, located above the primary conveyor frame, allowing material to enter the conveyor belt through the feeding hopper.

[0008] Preferably, the secondary conveyor frame and the rotating base are rotatably connected. The rotating base is connected to two sets of symmetrically distributed lifting and adjusting mechanisms. Each lifting and adjusting mechanism includes a primary telescopic cylinder rotatably connected to the rotating base. The other end of the primary telescopic cylinder is rotatably connected to a connecting crossbar, and the other end of the connecting crossbar is rotatably connected to a secondary telescopic cylinder.

[0010] Preferably, the secondary conveyor frame is fixedly connected to two opposing support vertical frames at one end near the primary conveyor frame. Each support vertical frame is slidably connected to a lifting bracket. A rotating shaft is rotatably connected between the two lifting brackets. Two symmetrically distributed pressure rollers are coaxially fixedly connected to the rotating shaft. The pressure rollers are elastic rollers. The lifting bracket and the supporting vertical frame are connected by a strong spring. Under the action of the strong spring, the pressure roller and the conveyor belt are in close contact.

[0011] Preferably, the feeding hopper includes a feeding bin fixedly connected to the rotating base. The lower end of the feeding bin is in the shape of a conical funnel. A material gathering hopper is placed at the lower end of the feeding bin and fixedly connected to the primary conveyor frame. The lower end face of the material gathering hopper is parallel to the conveyor belt. The lower end of the material gathering hopper has a shape with a larger opening at the top and a smaller opening at the bottom.

[0012] Preferably, an adjusting sealing plate is connected between the feeding hopper and the collecting hopper. The upper end of the adjusting sealing plate wraps around the lower part of the feeding hopper, and the lower end of the adjusting sealing plate is placed inside the collecting hopper.

[0026] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 8 The detailed description of the embodiments will make this clear. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0027] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] This invention relates to a port bulk material loading and unloading barge, comprising a barge 1, a grab barge 2, and a conveying device 3. The barge 1 is an existing type of barge. The grab barge 2 and the conveying device 3 are located at both ends of the barge 1. The grab barge 2 grabs bulk materials on the dock, and the grab barge 2 and the conveying device 3 work together to place the grabbed bulk materials onto the conveying device 3 for transport. A rotating base 4 is fixedly connected to the barge 1, and the grab barge 2 is rotatably connected to the rotating base 4, allowing the grab barge 2 to rotate circumferentially. The material is now being grabbed by rotating the rotating seat 4, which drives the rotating clamshell grab 2. After grabbing the material, the clamshell grab 2 is rotated and adjusted, and then the material is placed in the conveying equipment 3. The other end of the pontoon 1 is connected to a rotating disk 5, which is connected to a drive structure inside the pontoon 1. The conveying equipment 3 and the rotating disk 5 are fixedly connected, so that the conveying equipment 3 rotates around the pontoon 1 to transfer the material to the cargo ship. This ensures that after receiving the material, the conveying equipment 3 can adaptively adjust its unloading position according to different loading and unloading positions to ensure that the material can be loaded onto the ship.

[0029] The conveying device 3 includes a rotating base 6 fixedly connected to the rotating disk 5. The rotating base 6 and the rotating disk 5 are connected, and the rotation of the rotating disk 5 drives the rotating base 6 to rotate synchronously. A primary conveyor frame 7 is fixedly connected to the rotating base 6. A secondary conveyor frame 8 connected to the rotating base 6 is located at the end of the primary conveyor frame 7 away from the grab bucket 2. The primary conveyor frame 7 and the secondary conveyor frame 8 form a conveying system. A drive roller 9 is rotatably connected to the ends of the primary conveyor frame 7 and the secondary conveyor frame 8. The primary conveyor frame 7, the secondary conveyor frame 8 and the drive roller 9 are all connected to a conveyor belt 10. The conveyor belt 10 is concave. The conveyor belt 10 is shaped like the letter "U" to prevent material from slipping during the conveying process. One of the drive rollers 9 is connected to an external motor. When the drive roller 9 rotates, it drives the conveyor belt 10 to roll on the primary conveyor frame 7 and the secondary conveyor frame 8, thereby realizing the conveying of bulk materials. At the same time, the conveyor belt 10 is shaped like the letter "U" to prevent the bulk materials from falling off and to ensure that the materials will not slip to the sides during the conveying process. The upper end of the rotating base 6 is fixedly connected to the feeding hopper 11. The feeding hopper 11 is located at the upper end of the primary conveyor frame 7, so that the materials enter the conveyor belt 10 through the feeding hopper 11. The materials are then transferred from the shell grab bucket machine 2 to the conveying equipment 3 through the feeding hopper 11.

[0030] During the loading process, as the cargo gradually increases in height, and different transport devices have different heights, this embodiment provides a structure for adjusting the height of the unloading end of the conveying device 3. Specifically, the secondary conveyor frame 8 and the rotating base 6 are rotatably connected, allowing the secondary conveyor frame 8 to rotate around the rotating base 6, thus adjusting the height of the unloading end of the secondary conveyor frame 8. Two symmetrically distributed lifting adjustment mechanisms are connected to the rotating base 6, and the two sets of lifting adjustment mechanisms synchronously extend and retract. Each lifting adjustment mechanism includes a primary telescopic hydraulic cylinder 12 rotatably connected to the rotating base 6. The other end of the primary telescopic cylinder 12 is rotatably connected to a connecting crossbar 13, and the other end of the connecting crossbar 13 is rotatably connected to a secondary telescopic cylinder 14. The secondary telescopic cylinder 14 is rotatably connected to the secondary conveyor frame 8. The lifting and lowering adjustment of the secondary telescopic frame is achieved by the extension and retraction of the primary telescopic cylinder 12 and the secondary telescopic cylinder 14. When the unloading end of the secondary conveyor frame 8 needs to be adjusted downward, the primary telescopic cylinder 12 and the secondary telescopic cylinder 14 extend. Under the action of the connecting crossbar 13, the secondary conveyor frame 8 rotates downward, thereby moving the unloading end of the secondary conveyor frame 8 downward. The reverse is also true.

[0031] To ensure precise adjustment of the secondary conveyor frame 8 and prevent instability, a lifting lug 15 is fixedly connected to the secondary conveyor frame 8. A guide wheel 16 is rotatably connected to the upper end of the rotating base 6, and an adjusting wheel 17 is rotatably connected to the middle of the rotating base 6. The adjusting wheel 17 is connected to an adjusting motor connected to the rotating base 6. A pull rope is fixedly connected to the lifting lug 15. The pull rope passes around the guide wheel 16 and connects to the adjusting wheel 17. The adjusting motor drives the adjusting wheel 17, and the rotation of the adjusting wheel 17 stretches the pull rope. During the stretching process, the pitch adjustment of the secondary conveyor frame 8 is achieved. At the same time, the adjusting motor is a self-locking motor, which can prevent the pull rope from slipping under the gravity of the secondary conveyor frame 8.

[0032] In the process of adjusting the pitch angle of the secondary conveyor frame 8, in order to ensure that the conveyor belt 10 can slide smoothly and that the pitch of the secondary conveyor frame 8 does not cause the conveyor belt 10 to lift up or even deform and tear, resulting in material spillage during the material conveying process, this embodiment provides a structure to ensure that the conveyor belt 10 will not deform or tear and to ensure the smooth conveying of the conveyor belt 10. Specifically, two opposing support vertical frames 19 are fixedly connected to one end of the secondary conveyor frame 8 near the primary conveyor frame 7. Each support vertical frame 19 is slidably connected to a lifting bracket 20, and the two lifting brackets 20 are rotatably connected to each other. A rotating shaft 21 is provided, on which two symmetrically distributed pressure rollers 22 are coaxially fixedly connected. The pressure rollers 22 are elastic rollers. A sliding track is provided on the supporting vertical frame 19. A sliding limit block that cooperates with the sliding track is fixedly connected to the lifting bracket 20. The sliding limit block and the lifting bracket 20 are fixedly connected. A strong spring is connected between the sliding limit block and the sliding track. Under the action of the strong spring, the pressure rollers 22 contact the inner wall of the conveyor belt 10, thereby pressing the conveyor belt 10 and preventing it from tilting or deforming, thus avoiding a "U" shape.

[0033] To ensure that the material falls smoothly onto the conveyor belt 10, prevents it from floating outwards, and gathers it to ensure it lands in the middle of the conveyor belt 10, the hopper includes a feeding bin 23 fixedly connected to the rotating base 6. The lower end of the feeding bin 23 is cone-shaped funnel-shaped, collecting the material and then feeding it to the middle of the conveyor belt 10. A gathering hopper 24 is fixedly connected to the primary conveyor frame 7 at the lower end of the feeding bin 23. The lower end of the gathering hopper 24 is parallel to the conveyor belt 10, and its lower end has a shape with a larger opening at the top and a smaller opening at the bottom, ensuring that loose material falls into the middle of the conveyor belt 10. Simultaneously, the rear end of the gathering hopper 24 extends into the interior of the conveyor belt 10. Since the primary conveyor frame 7 is inclined, this prevents the material from sliding off the rear end of the primary conveyor frame 7.

[0034] An adjusting sealing plate is connected between the feeding bin 23 and the hopper 24. The upper end of the adjusting sealing plate wraps around the lower part of the feeding bin 23 to ensure that the material enters the interior of the adjusting sealing plate. The lower end of the adjusting sealing plate is placed inside the hopper 24. The adjusting sealing plate includes two arc-shaped guide chambers 25 rotatably connected to the lower end of the feeding bin 23. Each of the two arc-shaped guide chambers 25 is fixedly connected to a rotating gear 26. The two rotating gears 26 mesh with each other. One of the rotating gears 26 is connected to a drive mechanism connected inside the feeding bin 23. The drive mechanism drives the rotating gear 26, thereby ensuring that the arc-shaped guide chamber 25 rotates in the opposite direction, realizing the adjustment of the opening of the adjusting sealing plate. The opening of the adjusting sealing plate can be adaptively adjusted according to the material form, the amount of material fed per unit time, and the mass of the material.

[0035] Since the material conveying process mainly relies on the secondary conveyor frame 8 for high-altitude conveying, and given the significant impact of wind on the port environment, some lightweight materials may be blown off by the wind. Therefore, this embodiment provides a windproof structure. Specifically, an arc-shaped protective cover 27 is fixedly connected to the secondary conveyor frame 8 to protect the materials and prevent the environment from affecting them.

[0036] During the conveying process of some granular or easily rolling materials, the material may slide downwards. Prolonged sliding can lead to material accumulation, which in turn affects the material conveying process and may even cause the material conveying to be obstructed. Therefore, a structure is provided to prevent the material from slipping. Specifically, the conveyor belt 10 is fixedly connected with several sets of equally spaced stop block 28 assemblies. The stop block 28 assembly includes several sets of staggered stop blocks 28. The stop blocks 28 are rectangular and staggered to ensure that the stop blocks 28 can form a barrier line, thereby preventing the material from slipping.

[0037] The output end of the secondary conveyor frame 8 is fixedly connected to a cleaning frame 29. Several cleaning brushes 30 that cooperate with the conveyor belt 10 are fixedly connected to the cleaning frame 29. The cleaning brushes 30 are evenly distributed and connected to a storage box 31 connected to the lower end of the cleaning frame 29. The cleaning brushes 30 are used to clean the conveyor belt 10, preventing some adhesive substances from being conveyed and circulated again with the conveyor belt 10. At the same time, since there are several cleaning brushes 30, the conveyor belt 10 can be cleaned multiple times to ensure complete cleaning.

[0038] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
