[0002] Offshore platform oil-water supply is a routine work, and also a high-risk operation. The traditional way of supplying oil and water is to suspend the supply pipeline by crane, and then manually connect the quick connector of the supply pipeline with the fixed pipeline of the platform. The traditional operation method requires the cooperation of the crane throughout the process, and the operation method has great limitations and risks. If the weather and sea conditions are bad, the high risk of this operation is particularly prominent, and its disadvantages mainly manifest in the following aspects:

[0019] As Figs. 1-3 shown, an offshore platform diesel fresh water supply operation anti-unlocking locking device, including rolling bearing 1, hose push rod 2, fixed locking pin 3, main support frame 4, brake support frame 5, mechanical brake 6, fixed support column 7, driving motor 8, drum 9, hose stopper 10, hose locking pin 11, stopper handle 12, driving wheel 13, driven wheel 14, speed reducer 15, push disc 16.
[0020] The horizontal fixed pillar 7 is connected to the main support frame 4, and the end of the fixed pillar 7 away from the main support frame 4 is connected to the driven wheel 14 through the rolling bearing 1. The driven wheel 14 is below the driving wheel 13, and the driven wheel 14 is engaged with the driving wheel 13. The driving wheel 13 is sleeved on the output end of the driving motor 8, and the driving motor 8 is arranged on the main support frame 4. When the driving motor 8 works, the driving wheel 13 rotates, and the driving wheel 13 drives the driven wheel 14 to rotate. Since the rolling bearing 1 is arranged between the fixed pillar 7 and the driven wheel 14, the fixed pillar 7 does not rotate with the driven wheel 14, and the fixed pillar 7 plays a role in stabilizing the support of the roller 9.
[0021] The side of the driven wheel 14 of the utility model is sequentially connected with the speed reducer 15 and the roller 9. The speed reducer 15 is provided with the mechanical brake 6, and the mechanical brake 6 is arranged on the brake support frame 5. In daily operation or emergency, the mechanical brake 6 can brake the roller 9 in cooperation with the fixed locking pin 3. Specifically, the mechanical brake 6 includes a roller brake disc 61, the roller brake disc 61 is sleeved on the speed reducer 15, the roller brake disc 61 is formed with an opening, and a locking mechanism is arranged in the opening. More specifically, the locking mechanism includes connecting ears arranged on both sides of the opening of the roller brake disc 61, and locking bolts are arranged on the two connecting ears. The size of the opening of the roller brake disc 61 is controlled by the locking bolts, so as to limit the angular velocity of the rotation of the roller 9, and prevent the roller 9 from being accidentally pulled and the rotation speed being too fast to injure the operator.
[0022] A plurality of cutting seams 91 are formed in the end of the roller 9 away from the speed reducer 15. The cutting seams 91 are formed along the axial direction of the roller 9, and the cutting seams 91 can clamp the water (oil) supply pipe into the device. In order to prevent the water (oil) supply pipe from slipping out of the device, the soft pipe block 10 is slidably arranged on the end face of the roller 9. Specifically, the soft pipe block 10 is arranged on the end face of the roller 9, and the soft pipe block 10 is formed with an elongated through groove. The soft pipe block 11 is arranged in the through groove, and the soft pipe block 11 can slide in the through groove. In addition, in order to facilitate the movement of the soft pipe block 10, the block handle 12 is arranged on the soft pipe block 10.
[0023] The fixed pillar 7 is arranged in a hollow structure, and the soft pipe push rod 2 is arranged in the fixed pillar 7. One end of the soft pipe push rod 2 is connected to the push disc 16 and arranged on the roller 9, and the other end of the soft pipe push rod 2 is sleeved with a spring. The two ends of the spring are respectively arranged on the end handle of the soft pipe push rod 2 and the main support frame 4. After the operation is completed, the soft pipe push rod 2 can smoothly push the supply pipeline out of the device, so that the device is safely separated from the device. The arrangement of the spring facilitates the resetting of the soft pipe push rod 2 after the supply pipeline is pushed out.
[0024] The fixed locking pin 3 is arranged on the main support frame 4, and one end of the fixed locking pin 3 is inserted into a locking hole of the driven wheel 14.
[0025] The implementation process of the utility model includes two processes, first, the supply pipeline butt joint platform supply interface. When the crane hoists the flat supply pipeline to the utility model drum 9, the pipeline is manually entered into the winch drum inside along the slit 91 of the drum 9. Start the winch drum clockwise rotation, winding the pipeline on the drum 9 2-3 turns. After winding, the drum brake disc 61 is locked, and the fixed locking pin 3 is inserted into the locking hole of the driven wheel 14. Disconnect the crane and the supply pipeline, and hand over the supply pipeline to the utility model device stress. After manually butt joint pipeline and platform interface, rotate the corresponding hose block 10 in the counterclockwise direction, block the hose in the drum 9, prevent the hose from separating from the drum 9 when the drum 9 rotates, and slowly release the pipeline until the pipeline is completely separated from the utility model device. Second, after the supply operation is completed, the crane hoists the supply pipeline to the drum 9, and the subsequent steps are consistent with the butt joint pipeline steps. After the butt joint quick connector is released, the hose block 10 is rotated to the initial position, the supply pipeline is pushed out of the drum 9 by the hose push rod 2, and the supply pipeline is completely separated from the utility model device. Then, the crane is used to recover the pipeline.
[0026] In the operation and implementation process of the utility model device, the participation of the crane and the personnel is greatly reduced, and the damage to the personnel and the equipment caused by the hose rupture is reduced. At the same time, the whole implementation process is simple, safe and reliable, and has no additional safety risk.
[0027] The embodiments of the specific embodiment are preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so that: any equivalent changes made according to the structure, shape and principle of the utility model should be covered in the protection scope of the utility model.
