Description

Technical Field

[0001] The utility model relates to the technical field of lightering operation equipment, in particular to a lightering loading system. Background Art

[0002] Lightering operation is a kind of operation and loading method for transferring goods between two ships. For example, transferring the crushed stone materials loaded on a small ship to a large ship. In the prior art, generally, a lifting device (equipped with a material grabbing bucket) arranged on the shore is used to grab the materials on the small ship, and then after rotating a certain distance (angle), it falls onto the large ship. This requires the large ship and the small ship to be arranged side by side in front of the shore, with the large ship and the small ship parked one in front of the other. During actual operation, the small ship can flexibly approach the shore and achieve positioning. However, when the large ship approaches the shore, due to its larger hull, it is relatively inflexible. Improper operation is likely to cause a greater impact on the shore, making it difficult to load the ship. At the same time, the cargo hold of the large ship is also relatively longer. During loading, the lifting device needs to rotate within a larger range, and it is not easy to control the material dropping position (the material grabbing bucket needs to move horizontally in a direction parallel to the shore during the rotation of the lifting device). Eventually, the efficiency of the entire loading process is relatively low. Summary of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides a lightering loading system, which solves the problems in the prior art that it is not easy to move the large ship and it is not easy to control the material dropping position of the lifting device, resulting in a relatively low efficiency of the entire loading process.

[0004] According to an embodiment of the utility model, a lightering loading system includes a lifting device and a conveying device arranged side by side on the shore, wherein: the lifting device includes a mounting seat fixed on the shore and a lifting arm rotatably opposite to the mounting seat, and a material grabbing bucket is further connected to the lifting arm; the conveying device includes a feeding hopper and a first belt conveyor. The feeding hopper is fixedly arranged on the shore, and the materials in the feeding hopper can fall onto one end of the first belt conveyor, and the other end of the first belt conveyor extends in a direction perpendicular to the shore; the material grabbing bucket can be located directly above the feeding hopper during the rotation of the lifting arm.

[0005] In the above embodiment, the small ship and the large ship are arranged side by side, with the small ship close to the shore and the large ship on the other side of the small ship away from the shore. In this way, after the lifting device grabs the materials of the small ship through the material grabbing bucket, it transfers them to the feeding hopper, then falls onto the first belt conveyor through the feeding hopper, and then is conveyed onto the large ship through the first belt conveyor. During the process, the lifting device does not need to control the material dropping position, and the rotation adjustment is faster. The large ship does not need to approach the shore and is relatively easier to control. Therefore, the problems in the prior art that it is not easy to move the large ship and it is not easy to control the material dropping position of the lifting device, resulting in a relatively low efficiency of the entire loading process, are solved.

[0006] Further, the feeding hopper, the mounting seat, and one end of the first belt conveyor are all horizontally arranged on the shore. The lower end of the feeding hopper is the discharging port, and a second belt conveyor is also arranged between directly below the discharging port and directly above the end of the first belt conveyor located on the shore.

[0007] Further, the second belt conveyor is inclined, with the lower end located directly below the discharging port, and the higher end is also connected to a guiding hopper located directly above the first belt conveyor.

[0008] Further, the first belt conveyor extends horizontally.

[0009] Further, positioning piles are also fixedly connected to the shore.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The material is first transferred to the feeding hopper by the lifting device, and then conveyed to the large ship by the first belt conveyor. There is no need to control the falling point of the material by the lifting device, and at the same time, the large ship does not need to operate close to the shore. Therefore, the operation is more convenient, thus solving the problems in the prior art that it is difficult for the large ship to move and it is difficult to control the falling position of the lifting device, resulting in a low efficiency of the entire ship loading process.

[0016] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0017] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0018] In an exemplary embodiment, as Figure 1 , 2 shown, this embodiment provides a lightering and loading system, which includes a lifting device 2 and a conveying device 3 arranged side by side on the shore 1, wherein: the lifting device 2 includes a mounting seat 4 fixed on the shore 1 and a lifting arm 5 rotatably relative to the mounting seat 4, and a grab bucket 6 is further connected to the lifting arm 5; the conveying device 3 includes a feed hopper 7 and a first belt conveyor 8, the feed hopper 7 is fixedly arranged on the shore 1, and the material in the feed hopper 7 can fall onto one end of the first belt conveyor 8, and the other end of the first belt conveyor 8 extends in a direction perpendicular to the shore 1; the grab bucket 6 can be located directly above the feed hopper 7 during the rotation of the lifting arm 5.

[0019] In the above embodiment, the small boat 10 and the large ship 11 are arranged side by side, the small boat 10 is close to the shore 1, and the small boat 10 can be relatively positioned by the positioning piles 9 arranged on the shore 1. The large ship 11 is located on the other side of the small boat 10 away from the shore 1. In this way, after the lifting device 2 grabs the material of the small boat 10 through the grab bucket 6, it is transferred to the feed hopper 7, then falls onto the first belt conveyor 8 through the feed hopper 7, and then is conveyed onto the large ship 11 through the first belt conveyor 8. During the process, the lifting device 2 does not need to control the material dropping position, and the rotation adjustment is faster. The large ship 11 does not need to be close to the shore 1 and is relatively easier to control. Therefore, it solves the problems in the prior art that the large ship 11 is not easy to move and the material dropping position of the lifting device 2 is not easy to control, resulting in a lower efficiency of the entire loading process; the end of the first belt conveyor 8 away from the shore 1 is the material dropping point, which is relatively fixedly arranged. During the loading process, the material dropping point can be changed by moving the large ship 11 forward and backward, so as to achieve more uniform loading. Although the position of the large ship 11 needs to be adjusted, the large ship 11 does not need to be closer to the shore 1, only needs to move forward or backward, and the operation is simpler. Therefore, the overall efficiency is still improved.

[0020] In a further exemplary solution, as Figure 1 , 2As shown, the feed hopper 7, the mounting base 4, and one end of the first belt conveyor 8 are all horizontally arranged on the shore 1. The lower end of the feed hopper 7 is the discharge port, and there is also a second belt conveyor 12 provided between directly below the discharge port and directly above one end of the first belt conveyor 8 located on the shore 1. That is, the second belt conveyor 12 is also horizontally arranged. In particular, the second belt conveyor 12 can also be inclined. Its lower end is directly below the discharge port, and its higher end is also connected to a material guiding hopper 13 located directly above the first belt conveyor 8. The material guiding hopper 13 is vertically arranged, with the upper end being the inlet connected to the higher end of the second belt conveyor 12 and the lower end being provided with an outlet. The orthographic projection of the outlet is located on the first belt conveyor 8. The material in the feed hopper 7 is transferred to the first belt conveyor 8 through the second belt conveyor 12, and then falls onto the large ship 11 through the end of the first belt conveyor 8 that horizontally extends above the large ship 11, achieving ship loading. The reason for not directly dropping the material in the grab bucket 6 onto the first belt conveyor 8 is to avoid the impact on the first belt conveyor 8 during the falling process of the material. At the same time, the feed hopper 7 can also play a role in gathering the material, preventing it from falling off from the side and onto the ground after falling.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
