Description

Technical Field

[0001] This invention relates to the field of hydraulic shearing of waste materials, and in particular to a hydraulic shearing device for marine waste disposal. Background Technology

[0002] With the continuous advancement of marine development, the service life of offshore oil platforms, pipelines, and other facilities is increasing year by year, and the need to dismantle facilities exceeding their service life is becoming increasingly urgent. The disposal of marine debris such as subsea pipelines, jacket platforms, and monopile platforms has become an important issue in the field of marine engineering. In the process of marine debris disposal, cutting operations are a key link. However, traditional cutting processes have many drawbacks: the conventional oxyacetylene thermoelectric cutting method has low construction efficiency, especially for complex structures such as double-layer casings, which require layer-by-layer cutting, seriously slowing down the construction progress and leading to a significant increase in the costs of offshore labor and vessels, increasing the difficulty of project cost control; at the same time, marine debris is often covered with oil, and thermoelectric cutting can easily cause fires, explosions, and other safety hazards, threatening the lives of workers, and the pollutants produced by combustion will damage the marine ecological environment.

[0003] Furthermore, existing shearing equipment suffers from insufficient adaptability and functionality: traditional hydraulic shears are mostly used in conjunction with excavators, but excavators are difficult to deploy on offshore work platforms such as ship decks, limiting the operational range; some shearing devices lack precise position adjustment functions, failing to flexibly adapt to different positions and angles of marine debris; and during the shearing process, debris is prone to swaying and shifting, affecting shearing accuracy and safety. The residue and oil contamination left on the shear blades after shearing also require additional manual cleaning, further reducing operational efficiency. Therefore, there is an urgent need for a safe, environmentally friendly, highly efficient, precise, adaptable marine debris shearing device with cleaning capabilities to address the shortcomings of traditional processes and existing equipment.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] like Figures 2-3As shown, the adjustment mechanism 1 includes an adjustment base 101 and an adjustment sliding plate 102 slidably disposed on the adjustment base 101.

[0031] like Figures 4-5 As shown, the shearing mechanism 2 includes a connecting plate 201 fixedly mounted on the support frame 107, a shearing frame 202 mounted on the connecting plate 201, a hydraulic cylinder 203 rotatably mounted on the shearing frame 202, a lower shearing blade 205 fixedly mounted on the shearing frame 202, and an upper shearing blade 204 rotatably mounted on the shearing frame 202. The telescopic end of the hydraulic cylinder 203 is rotatably connected to the upper shearing blade 204.

[0032] The shearing frame 202 is also fixedly equipped with an upper detection electric cylinder 2063 and a lower detection electric cylinder 2064. The upper detection electric cylinder 2063 is provided with an upper detection block at its telescopic end, and the upper detection block is provided with an upper detection head 2061. The lower detection electric cylinder 2064 is provided with a lower detection slider at its telescopic end. The lower detection slider is slidably connected to the shearing frame 202, and the lower detection slider is provided with a lower detection head 2062.

[0033] The shearing frame 202 is provided with cleaning nozzles 207 on both sides of the upper shear blade 204.

[0034] like Figures 6-9 As shown, the clamping mechanism 3 includes a clamping frame 301 slidably mounted on the shearing frame 202, and a push-in electric cylinder 307 fixedly mounted on the shearing frame 202. The telescopic end of the push-in electric cylinder 307 is fixedly connected to the clamping frame 301. A main clamping finger 303 is rotatably mounted on the clamping frame 301. The main clamping finger 303 is provided with an arc-shaped rack and a locking hole. A clamping motor 302 and a locking electric cylinder 305 are fixedly mounted on the clamping frame 301.

The main clamping finger 303 is also fixedly provided with a clamping electric cylinder 308. The extension end of the clamping electric cylinder 308 is provided with a secondary clamping finger 304.

[0035] like Figure 1 , Figure 10 As shown, a waste bin 4 is also provided at the bottom of the adjusting base 101, and a cleaning mechanism 5 is provided on one side of the adjusting base 101. The cleaning mechanism 5 includes a cleaning bracket 505 fixedly connected to the adjusting base 101. A cleaning motor 501 is fixedly provided on the cleaning bracket 505. A lead screw 502 is provided at the output end of the cleaning motor 501. A groove for accommodating the lead screw 502 is provided on the cleaning bracket 505. A movable frame 503 is also slidably provided on the cleaning bracket 505. The lead screw 502 is threadedly connected to the movable frame 503. A roller brush motor 506 is provided on the movable frame 503. A cleaning roller brush 504 is provided at the output end of the roller brush motor 506.

[0036] Furthermore, this equipment is specifically designed for near-surface offshore operations, facing harsh working environments characterized by high humidity, high salt spray, and strong corrosion. To ensure operational stability, extend service life, and prevent functional failures caused by corrosion, all core components employ targeted protective designs: metal structural parts are made of seawater-resistant 316L stainless steel or treated with a composite coating of epoxy zinc-rich primer and fluorocarbon topcoat; piston rods of moving parts such as electric and hydraulic cylinders are chrome-plated or nitrided, coupled with double fluororubber seals to prevent seawater from seeping into the cylinder body; electrical components such as the detection head and motor are designed with an IP67 or higher protection rating, with sealed outer shells and internal electronic components encapsulated with epoxy resin to isolate moisture and salt spray; auxiliary components such as the cleaning nozzle 207 and cleaning roller brush 504 are made of aging-resistant and corrosion-resistant materials, and the waste bin 4 is equipped with a drainage structure to prevent seawater accumulation. This comprehensive anti-corrosion design ensures continuous and reliable operation of the equipment in high-humidity and high-corrosion environments, effectively reducing maintenance costs and the risk of failure.

[0037] Working principle: The adjusting base 101 is fixed on the offshore working platform, such as the deck of a ship. Then, the telescopic electric cylinder 103 is activated to push the adjusting base 101 into the near-water area where the clamping operation is to be carried out. Then, the pitch electric cylinder 104 is activated. The quadrilateral linkage structure formed by the adjusting sliding plate 102, U-shaped frame 105, connecting arm 106 and support frame 107 can realize the pitch angle adjustment of the shearing mechanism 2 and the clamping mechanism 3.

[0038] Start the push-in electric cylinder 307 to adjust the clamping frame 301 to the working position. In the initial state, the main clamping finger 303 is perpendicular to the shearing frame 202. Use the adjustment mechanism 1 to adjust the shearing mechanism 2 and the clamping mechanism 3 in front of the workpiece to be sheared. Start the clamping motor 302 to lift the main clamping finger 303 and support the workpiece to be sheared. At this time, the workpiece to be sheared is lifted by the two main clamping fingers 303 and the lower shearing blade 205. Start the locking electric cylinder 305. The locking pin on the locking frame 306 cooperates with the locking hole on the main clamping finger 303 to lock the position of the main clamping finger 303. Start the clamping electric cylinder 308 to push the auxiliary clamping finger 304 to clamp the workpiece to be sheared. Then use the adjustment mechanism 1 to transport the workpiece to be sheared to the offshore operation platform.

[0039] Before starting the shearing operation, it is necessary to check whether there are foreign objects such as oil stains on the surface of the workpiece to be sheared. If there are foreign objects such as oil stains on the surface of the tool to be sheared, open the cleaning nozzle 207 and spray cleaning fluid into the shearing operation position to further ensure the shearing effect.

[0040] After clamping the workpiece, the clamping mechanism 3 starts the upper detection cylinder 2063 and the lower detection cylinder 2064 to move the upper detection head 2061 and the lower detection head 2062 to the upper and lower positions of the workpiece and detect the position of the workpiece. If an accident occurs during the shearing process, the shearing can be stopped immediately to ensure the safety of the operation.

[0041] Start the hydraulic cylinder 203, and the upper shear blade 204 moves downward to shear the workpiece. The waste generated by shearing falls into the waste bin 4 below. After the shearing operation is completed, release the clamping mechanism 3 and remove the workpiece to complete the shearing operation.

[0042] After the shearing operation is completed, the upper shear blade 204 and lower shear blade 205 on the shearing mechanism 2 are adjusted to the positions corresponding to the cleaning roller brush 504 using the adjusting mechanism 1. The cleaning motor 501 is started, so that the cleaning roller brush 504 moves between the upper shear blade 204 and the lower shear blade 205. Then the roller brush motor 506 is started, so that the cleaning roller brush 504 rotates to start cleaning the upper and lower shear blades. After cleaning is completed, the cleaning motor 501 is reversed to reset, and the cleaning operation is completed.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
