Description

Technical Field

[0001] This utility model relates to the field of sand loading and unloading technology, specifically a sand loading and unloading device. Background Technology

[0002] Sand extraction and loading refers to the process of transferring dredged sand from dredgers or transport vehicles to barges or other loading vehicles using lifting equipment (such as floating cranes and shore cranes) during dredging projects. This operation is a special application scenario of lifting operations and requires special management in combination with the water environment, vessel cooperation and safety regulations. Dredging vessels carry out dredging operations in accordance with conventional construction methods. Underwater soil is transported to the barge platform through the floating pipe connecting the dredging vessel and the loading platform. After that, it flows through the modified mud conveying branch pipe to load sand transport vessels moored on both sides of the barge. After the sand transport vessels reach the target loading volume, they sail away to the designated location to dump mud, completing one cycle of dredging and sand extraction operation.

[0003] However, existing sand extraction and barge loading processes suffer from the following problems: During cutter suction barge loading, due to differences in sand transport vessel size and compartment structure, frequent adjustments to the vertical height and horizontal swing amplitude of the loading pipe are necessary to control the flatness of the loading compartments, increase the loading capacity, and improve overall operational efficiency. However, existing sand extraction and barge loading equipment has a low degree of automation during the lifting process and insufficient flexibility in adjusting the loading pipe. Therefore, corresponding technical solutions need to be designed to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a sand-taking barge hoisting device, which solves the technical problem that in the process of cutter suction barge construction, due to the different sizes and compartment structures of sand transport vessels, it is necessary to frequently adjust the vertical height and horizontal swing amplitude of the barge loading pipe to control the flatness of the loading compartment, increase the loading capacity, and improve the overall operation efficiency. However, the existing sand-taking barge hoisting devices have a low degree of automation during the hoisting process and insufficient flexibility in adjusting the barge loading pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand-collecting and barge-loading hoisting device, comprising a column, reinforcing plates, a rectangular tube, a winch, lifting wires, ground wheels, roller assemblies, and an electric hoist.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a sand-loading and barge-lifting device, comprising a column 1, a reinforcing plate 2, a rectangular tube 3, a winch 4, a lifting wire 5, a ground wheel 6, a roller assembly 7, and an electric hoist 8. The column 1 is vertically welded to the barge platform deck. The reinforcing plate 2 is divided into several groups and evenly welded between the column 1 and the barge platform deck. The rectangular tube 3 has a four-section structure and includes a horizontal tube 9, a horizontal tube 10, a bushing 11, a vertical tube 12, and an inclined tube 13. The horizontal tube 9 and the horizontal tube 10 are horizontally arranged and rotatably connected by the bushing 11. The vertical tube 12 is vertically installed directly below the horizontal tube 10, and its lower end is connected to the roller assembly 7. The roller assembly 7 is located on the side of the column 1. The inclined tube 13 is fixed at an angle between the horizontal tube 10 and the vertical tube 12. The winch 4 is installed on the horizontal tube 9 and connected to the lifting wire 5. The ground wheel 6 is installed at the outer end of the horizontal tube 10. The lifting wire 5 passes through the ground wheel 6. The ground wheel 6 is located at the end of the rectangular tube 3 near the outlet of the loading pipe and is mainly used to guide the lifting wire 5. The electric hoist 8 is divided into two groups and located on both sides of the rectangular tube 3. In addition, the roller assembly 7 includes a welding plate 14 and two sets of rollers 15 installed on the inner side of the welding plate 14. The welding plate 14 is welded to the lower end of the vertical tube 12. The rollers 15 are in contact with the side of the column 1.

[0019] Further improvements, such as Figure 2 As shown, two sets of reinforcing plates 16 are welded to the middle and top of the column 1. The outer ends of the reinforcing plates 16 are fixedly connected to the deck of the loading platform, and the reinforcing plates 16 are set horizontally.

[0020] Further improvements, such as Figure 1 As shown, the traction end of the electric hoist 8 is connected to the rectangular tube 3 via a steel wire. The electric hoist 8 is installed within a 2-meter range on both sides of the rectangular tube and is used to adjust the left and right swing amplitude of the rectangular tube 3.

[0021] Further improvements, such as Figure 4 As shown, the two sets of rollers 15 are symmetrically arranged and are horizontally distributed. The two sets of rollers 15 rotate along the surface of the column 1. During the rotation of the rectangular tube 3, the rollers 15 rotate and adjust along the surface of the column 1.

[0022] Specifically, a pipe sealing plate 17 is welded to the tail of the horizontal pipe 9, and a sealing plate 18 is welded to the upper end of the inclined pipe 13 to prevent rainwater and mud from entering the pipe body.

[0023] In use: When it is necessary to adjust the height of the loading pipe, the hoist 4 pulls the lifting wire 5 along the ground wheel 6 to adjust the height of the loading pipe. When it is necessary to adjust the left and right position of the loading pipe, the electric hoist 8 pulls the wire 5, and the wire 5 pulls the rectangular tube 3 to swing left and right. The rectangular tube 3 rotates around the bushing 11, and at the same time, the roller 15 at the lower end rotates along the surface of the column 1 to achieve the purpose of smooth and efficient left and right swing adjustment of the rectangular tube 3 and the loading pipe.
