Description

Technical Field

[0001] This utility model relates to the field of marine oil engineering technology, and in particular to a stone transfer and cleaning device for marine sand dumping and backfilling equipment. Background Technology

[0002] With the continuous development of shallow-sea oil fields, submarine pipelines and cables have become crucial development facilities. Due to the complex marine dynamics, shallow engineering geology, and seabed dynamic geomorphology in shallow sea areas, the soft seabed foundation undergoes complex changes under repeated wave and current erosion, resulting in numerous submarine pipelines and cables being suspended near their bottoms. This suspension and exposure of submarine pipelines and cables pose a serious safety hazard, and is quite common in shallow-sea areas with soft seabed foundations at depths of 20-30 meters. Over time, this phenomenon is intensifying, seriously jeopardizing the production capacity and safety of offshore oil fields. If not detected and addressed promptly, the external forces caused by the suspension may exceed the stress strength of the pipeline itself, leading to leaks or cable breakage, resulting in significant environmental pollution and economic losses.

[0003] While various remediation methods exist, bottom sand filling and compaction remain the primary approach for exposed, suspended submarine cable sections. Although sand filling equipment can solve the current challenges of managing suspended submarine cables and ensure construction safety, its automation level during stone transport and cleaning is relatively low. This makes stone cleaning time-consuming, labor-intensive, and lacks specialized machinery. If there is a large amount of accumulated stone and conditions permit, loaders such as bulldozers can be used to shovel and transport thicker piles of stone to designated locations, effectively improving material transport and cleaning efficiency, but this is easily limited by site constraints. Using more efficient automated equipment, such as intelligent robotic arms, to clean and transport stone, and utilizing advanced sensor technology to monitor and analyze stone accumulation, offers high accuracy and speed, significantly reducing manual labor and improving overall efficiency, but at a relatively high cost.

Detailed Implementation

[0026] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0027] like Figure 1-2 As shown, a stone material transfer and cleaning device mainly includes a trolley frame 1, a horizontal conveying mechanism 2, a screw conveying mechanism 3, a hoisting mechanism 4, an operating room 5, a cleaning mechanism 6, and a lifting trolley 7.

[0028] The lifting trolley 7 is slidably connected to the main frame 1. The lifting trolley 7 is equipped with a horizontal conveying mechanism 2. The upper ends of the horizontal conveying mechanism 2 and the screw conveying mechanism 3 are fixedly connected. The horizontal conveying mechanism 2 and the screw conveying mechanism 3 move back and forth with the main frame 1.

[0029] The large vehicle frame 1 is also equipped with a winch lifting mechanism 4, which is fixedly connected to the horizontal conveying mechanism 2 and the screw material handling mechanism 3. The horizontal conveying mechanism 2 and the screw material handling mechanism 3 move up and down under the action of the winch lifting mechanism 4.

[0030] like Figure 3As shown, the screw conveyor mechanism 3 is mounted on the lifting trolley 7 and can move up and down along the main frame 1 with the lifting trolley 7, and also move back and forth with the main frame 1. Specifically, the screw conveyor mechanism 3 includes a bearing seat 10, screw blades 11, a material receiving roller 12, screw conveyor cutting teeth 13, and a screw conveyor inlet 14. The outer wall of the material receiving roller 12 is fixedly connected to the screw blades 11, the bottom of the material receiving roller 12 is fixedly connected to the screw conveyor inlet 14, the screw conveyor cutting teeth 13 and the screw blades 11 are fixedly connected, and the upper part of the material receiving roller 12 is pivotally connected to the bearing seat 10, causing relative rotation.

[0031] like Figure 4 As shown, the cleaning mechanism 6 is vertically mounted on the lower surface of the lifting trolley 7, installed on the side opposite to the forward movement of the device, and rigidly connected to it. It is used to clean the remaining stone material after the spiral material handling mechanism 3 has worked. Specifically, the cleaning mechanism 6 includes cleaning mechanism cutting teeth 15, a wire brush 16, and a rotating drum 17. The cleaning mechanism cutting teeth 15, wire brush 16, and rotating drum 17 are fixedly connected. The rotating drum 17 is driven to rotate by a motor. The wire brush 16 is used to clean the remaining smaller stone debris in the stone pool 9 after the spiral material handling mechanism 3 has worked.

[0032] like Figure 5 As shown, the horizontal conveying mechanism 2 includes a horizontal conveying mechanism inlet 18, a material receiving wall 19, a screw shaft 20, and a horizontal conveying mechanism outlet 21. The sections of the long-distance conveying cylinder are connected by flanges and sealed with gaskets. When the horizontal conveying mechanism 2 is working, the screw shaft 20 is driven to rotate by a motor.

[0033] like Figure 6 As shown, the trolley frame 1 includes a column guide rail 22, a column 23, limiters 24, and traveling wheels 25. The column 23 is equipped with the column guide rail 22 for lifting the trolley 7, ensuring normal lifting and lowering movement. Limiters 24 are located at both the upper and lower ends of the column guide rail 22 to control the maximum lifting position of the trolley 7. A through-beam laser detector 8 (model DA208Y-2) is mounted on the bottom crossbeam of the trolley frame 1 to detect edge signals of the stone quarry 9. The trolley frame 1 also includes an operator's cab 5.

[0034] like Figure 7As shown, the lifting trolley 7 mainly provides lifting motion and load-bearing function, including the lifting trolley discharge port 26, trolley frame 28, material conveying transfer 29, bottom support guide wheels 30, and lifting guide block 31. The trolley frame 28 is equipped with a horizontal material conveying mechanism 2, which is connected to the screw conveyor mechanism 3 via the material conveying transfer 29. The stone material conveyed by the screw conveyor mechanism 3 is buffered in the material conveying transfer 29 before entering the horizontal material conveying mechanism 2. The horizontal material conveying mechanism discharge port 21 is connected to the lifting trolley discharge port 26 and is located above the lifting trolley discharge port 26. The lifting guide block 31 moves along the main trolley column guide rail 22 to ensure the normal lifting motion of the lifting trolley 7.

[0035] like Figure 8 As shown, the hoisting mechanism 4 is mounted on the main frame 1 and is used to drive the lifting trolley 7, the screw conveyor mechanism 3, the horizontal conveying mechanism 2, and the cleaning mechanism 6 to move in the vertical plane. Specifically, the hoisting mechanism 4 mainly consists of a motor 34, a hydraulic brake 33, a reducer 32, a drum 27, and a locking device 35. During operation, the motor 34 drives the drum 36 to rotate, winding the rope to complete the lifting process.

[0036] The working process of this utility model:

[0037] When the device is started, the trolley frame 1 moves forward. When the through-beam laser detector 8 on the crossbeam at the bottom of the trolley detects the edge of the stone hopper 9, the traveling mechanism of the trolley frame 1 brakes, and the hoisting mechanism 4 on the top of the trolley operates, lowering the lifting trolley 7 along the column guide rail 22. The spiral material handling mechanism 3 connected to the lower end of the lifting trolley 7 rotates and descends. The spiral material handling mechanism cutting teeth 13 of the spiral material handling mechanism 3 feeds the stone from the spiral material handling mechanism inlet 14 into the spiral material handling mechanism 3. The lifting spiral inside the spiral material handling mechanism 3 rotates in the opposite direction to the spiral material handling mechanism cutting teeth 13, pushing the stone vertically upward. When it reaches the top of the lifting spiral, it enters the horizontal material handling mechanism 2 through the material transfer 29, and is then sent to the designated position outside the stone hopper 9. As the lifting trolley 7 continues to descend, the bottom support guide wheel 30 under the trolley contacts the bottom wall of the stone quarry 9. At this time, the steel wire rope connecting the lifting trolley 7 releases tension. When the pin-type sensor in the winch detects that the tension of the steel wire rope is less than the set value, the winch lifting mechanism 4 stops operating, and the traveling mechanism of the trolley frame 1 operates, driving the bottom support guide wheel 30 at the bottom of the lifting trolley 7 to continue moving forward. The spiral blades 11 on the outside of the spiral material handling mechanism 3 are equipped with high-strength spiral material handling mechanism cutting teeth 13. The two symmetrically arranged spiral material handling mechanisms 3 move forward under the drive of the trolley in opposite directions of rotation. The stone enters the spiral material handling mechanism inlet 14 along the spiral blades 11 on the outside of the spiral material handling mechanism 3, and is finally transported out of the stone quarry 9 by the horizontal conveying mechanism 2. The cleaning mechanism 6 is also a roller cutting tooth mechanism. The roller cutting tooth mechanism rotates, and the power is provided by the motor. It is lowered together with the lifting trolley 7. It collects the stones that are missed after the spiral material handling mechanism 3 has worked, and transfers the missed stones to the spiral material handling mechanism 3 through the rotation of the four roller cutting tooth mechanisms, so as to realize the transfer of stones.

[0038] When the through-beam laser detector 8 on the trolley frame 1 detects the edge signal at the end of the stone hopper 9, the trolley frame 1 brakes, the horizontal conveying mechanism 2 transports all the stones to the designated location, and the hoisting mechanism 4 lifts the lifting trolley 7, thus ending the operation.

[0039] This invention enables the transfer of stone materials in marine sand dumping and backfilling equipment. It features a simple structural design, greatly improved automation, safe and convenient operation, and reduced workload for workers while enhancing safety.

[0040] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully described in the technical requirements.
