Description

Technical Field

[0001] This utility model specifically relates to the field of underwater loading and unloading technology, and more specifically to an underwater loading and unloading machine. Background Technology

[0002] In fields such as water conservancy projects (river and reservoir dredging) and marine engineering (submarine pipeline maintenance and marine engineering facility foundation cleaning), it is often necessary to clean underwater silt and sediment. Ordinary land-based engineering machinery (such as excavators) lacks sufficient waterproof and pressure-resistant capabilities, making it difficult to operate stably underwater for extended periods. Its wading depth and sealing performance cannot meet the requirements of complex underwater environments (such as undercurrents and high pressure), making it prone to mechanical failure due to water ingress, resulting in high maintenance costs and a significant risk of operational interruption. The lack of targeted underwater loading and conveying structures leads to poor coordination between sludge dredging and transportation. For example, conventional dredging equipment relies on a "crush-suction" mode, which easily results in diluted sludge with excessively high water content, making subsequent processing difficult; it is also ineffective at clearing blocky debris and tangled objects (such as abandoned fishing nets and wooden stakes), and is prone to jamming the equipment. The underwater environment has poor visibility, making it difficult for traditional equipment to accurately locate the work area and control the loading force. This can easily damage underwater foundations (such as riverbed revetments and anti-corrosion layers for subsea pipelines), or cause equipment to shift due to rudimentary traction and guidance structures, resulting in missed cleaning dead spots. Dredging involves multiple stages, including loading, transportation, power supply, and control. In the existing scheme, the equipment is scattered (such as the power unit and the control panel being far away from the work area), the cables and ropes are messy, the signal transmission is easily interfered with, and the start-up and shutdown of each piece of equipment and the rhythm of operation are manually coordinated, making the process cumbersome and inefficient. Utility Model Content

[0003] The purpose of this utility model is to provide an underwater loading and unloading machine. In this device, through equipment location planning (ground transportation and hoisting, underground loading and unloading and discharge), a continuous operation chain of "loading → temporary storage → transportation → discharge" is constructed, reducing equipment waiting time and significantly improving dredging efficiency. Vibration motors are symmetrically installed on both sides of the hopper, and high-frequency vibration breaks up silt clumps, effectively avoiding blockage of the discharge port by large volumes of silt and ensuring continuous material transmission; thereby solving the problems mentioned above in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An underwater loading and unloading machine includes a sludge transport vehicle; wherein the sludge transport vehicle and the crane are arranged side by side in the ground operation area; it also includes a guide wheel assembly at the wellhead, a traction winch, a cable reel, a control console, and a generator set arranged sequentially on a ground support next to the wellhead, with the spacing between adjacent equipment being 0.5-1 meters. Meters; the lower guide wheel assembly at the wellhead is fixed below the inner wall of the wellhead and aligned vertically with the upper guide wheel assembly at the wellhead; the loader is located in the underwater working area, with a traction connection point above the rear of its vehicle body; the traction rope of the traction winch is led out from the winch body, passes sequentially around the upper pulley of the upper guide wheel assembly at the wellhead and the lower pulley of the lower guide wheel assembly at the wellhead, and is fixed to the traction connection point of the loader by a shackle; the hopper is suspended above the sludge transport bucket of the loader, with the edge of the hopper fitting against the inner wall of the sludge transport bucket; the feed end of the transmission pipe is inserted into the discharge port at the bottom of the hopper, and the discharge end is connected to the discharge port, which is fixed to the side of the loader's vehicle body by a bracket; there are two vibrating motors, symmetrically installed on the outer walls of both sides of the hopper; As a further technical solution of this utility model, the sludge bucket of the loader is a rectangular bucket with an open top; the top edge of the bucket is provided with a suspension ear plate, which is connected to the lifting point on the top of the loader body by a steel wire rope; one end of the transmission pipe is located above the bucket. As a further technical solution of this utility model, the guide wheel assembly at the wellhead includes two parallel fixed pulleys, which are mounted on a steel bracket above the edge of the wellhead via bearings. The bracket is fixed to the concrete foundation at the edge of the wellhead via expansion bolts. The guide wheel assembly at the wellhead includes two parallel fixed pulleys, which are mounted on a steel bracket below the inner wall of the wellhead via bearings. The bracket is welded and fixed to the pre-embedded steel plate on the inner wall of the wellhead. The traction rope of the traction winch is a steel wire rope, and a steel wire rope clamp is provided at the fixed point where the steel wire rope connects to the traction connection point of the loader. As a further technical solution of this utility model, two symmetrically arranged vibrating motors are fixedly installed on the outer wall of the sludge conveying bucket; multiple discharge ports are opened on the top of the side walls at both ends of the sludge conveying bucket. Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through equipment location planning (ground transportation and hoisting, underground loading and unloading), constructs a continuous operation chain of "loading → temporary storage → transportation → unloading", reducing equipment waiting time and improving dredging efficiency by more than 40%; 2. In this utility model, the upper and lower guide wheel groups are vertically aligned, which forcibly constrains the trajectory of the traction rope, so that the vertical lifting deviation of the loader is ≤5°, avoiding equipment tilting and damage, and ensuring full coverage of the dredging area; 3. In this utility model, vibrating motors are symmetrically installed on both sides of the hopper. The high-frequency vibration breaks up the sludge clumps, reducing the blockage rate of the discharge port from 35% to below 5%, ensuring continuous material transmission. 4. In this utility model, the generator set and the control panel are arranged close together, and the cables are wound and unwound in an orderly manner through the reel, which reduces the mess of wiring, shortens the troubleshooting time by 60%, and improves the energy utilization rate by centralized power supply. 5. This utility model: The nested connection between the hopper and the loading machine bucket and the transmission pipe eliminates gap leakage, increases the material collection rate to over 95%, and reduces underwater pollution.

The traction rope of the winch 4 is led out from the winch body, passes in sequence around the upper pulley of the upper guide wheel group 3 at the wellhead and the lower pulley of the lower guide wheel group 8 at the wellhead, and is fixed to the traction connection point of the loader 12 by a shackle; the hopper 9 is suspended above the sludge transport hopper 13 of the loader 12, and the edge of the hopper 9 is in contact with the inner wall of the sludge transport hopper 13; the feed end of the transmission pipe 10 is inserted into the discharge port at the bottom of the hopper 9, and the discharge end is connected to the discharge port 11, which is fixed to the side of the loader 12 by a bracket; there are two vibrating motors 14, which are symmetrically installed on the outer walls of both sides of the hopper 9; The sludge hopper 13 of the loader 12 is a rectangular hopper with an open top; the top edge of the hopper 9 is provided with a hanging ear plate, which is connected to the top suspension point of the loader 12 by a steel wire rope; one end of the transmission pipe 10 is located above the hopper 9.

[0011] By adopting the above technical solution, the crane 2 is used to lift the loader 12, which is connected with the cable and the traction wire rope, into the drainage pipe. The traction winch and cable drum are controlled to run the loader 12 to wind up and unwind the wire rope and cable. The crane 2 is used to lift the sludge bucket 13 into the drainage pipe. The loader 12 is remotely controlled to connect the linkage manipulator to the sludge bucket. In this embodiment, the upper guide wheel assembly 3 at the wellhead includes two parallel fixed pulleys, which are mounted on a steel bracket above the edge of the wellhead via bearings. The bracket is fixed to the concrete foundation at the edge of the wellhead via expansion bolts. The lower guide wheel assembly 8 at the wellhead includes two parallel fixed pulleys, which are mounted on a steel bracket below the inner wall of the wellhead via bearings. The bracket is welded and fixed to the pre-embedded steel plate on the inner wall of the wellhead. The traction rope of the traction winch 4 is a steel wire rope, and a steel wire rope clamp is provided at the fixed point of the steel wire rope and the traction connection point of the loading machine 12.

By adopting the above technical solution, the remotely controlled crane 2 pulls the sludge bucket 13 to the work area, controls the crane 2 bucket to carry out sludge removal operations, and digs or shovels the deposited sludge into the sludge bucket 13 behind. Furthermore, after the sludge bucket 13 is filled with sludge, it retreats to below the wellhead, and the loader 12 disconnects from the sludge bucket 13; the crane 2 lifts the sludge bucket 13 up and transfers the sludge to the sludge transport vehicle 1, which then transports the sludge to the designated storage site. In this embodiment, during the filling of sludge, the load of the sludge bucket 13 is effectively controlled by the discharge ports 11 opened on the side walls at both ends of the sludge bucket 13. When the filled sludge exceeds the position of the discharge port 11, it can be automatically discharged, avoiding damage to the traction device caused by the large size of the sludge bucket 13. Furthermore, during the discharge process, the vibration motors 14 installed on both sides of the sludge bucket 13 are controlled to work, effectively cleaning the inside of the sludge bucket 13. This prevents a large amount of sludge from adhering to the inner wall of the sludge bucket 13 during long-term use, thus affecting the load capacity of the sludge bucket 13.
