A dockside oil loading and unloading boom with a quick release device

Abstract

This utility model discloses a dock oil loading and unloading arm with a quick separation device, including a support arm structure, a flange adapter pipe, a synchronization mechanism, and a driver. A first ball valve is installed on the support arm structure, and the first ball valve is connected to a second ball valve. Two clamps are slidably connected to the flange adapter pipe via sliding parts. The two clamps fit around the joint between the second ball valve and the flange adapter pipe. Two synchronization mechanisms are provided and rotatably connected to the flange adapter pipe. The clamps are rotatably connected to the synchronization mechanisms. The driver is connected to the two clamps. When the second ball valve and the flange adapter pipe are quickly separated, the driver uses a fixed seat to push the two clamps to move horizontally. The two clamps move simultaneously under the action of a central rod and push-pull, no longer jamming the joint between the second ball valve and the flange adapter pipe. The second ball valve separates from the flange adapter pipe without damage to any parts. After the second ball valve and the flange adapter pipe are reconnected, the two clamps are locked, allowing for quick resumption of use.

Description

Technical Field

[0001] This utility model relates to the field of marine loading and unloading arm technology, specifically a dock oil loading and unloading arm with a quick release device. Background Technology

[0002] With the rapid development of the domestic liquefied natural gas market, the application of LNG receiving terminals in major ports is becoming more and more widespread, and the transportation volume of LNG ships is also expanding rapidly. After LNG ships berth at the terminal, the pipeline between the ship and the terminal needs to be connected by loading and unloading arms to realize the transfer of LNG from the ship to the terminal.

[0003] In related technologies, a search revealed a solution for an LNG shore-based intelligent loading and unloading arm (announcement number CN111664353B). The clamping rod is equipped with a shearing pin, which is inserted into the clamping rod and another valve clamp. The shearing pin acts as an anti-detachment component of the clamping rod, preventing the clamping rod from falling off during normal operation. During separation operations, the clamping rod can be pushed by a push block to cut off the shearing pin, thus functioning as an emergency detachment device.

[0004] However, the above solution, after cutting off the shear pin to separate the cryogenic upper ball valve and the cryogenic lower ball valve, requires a new shear pin to be prepared and the shear pin to be reset when connecting the cryogenic upper ball valve and the cryogenic lower ball valve. This is not convenient enough and cannot achieve non-destructive separation of the cryogenic upper ball valve and the cryogenic lower ball valve. Utility Model Content

[0005] The purpose of this invention is to provide a dock oil loading and unloading arm with a quick release device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dock oil loading and unloading arm with a quick release device, including a support arm structure, on which a first ball valve is installed, the first ball valve is connected to a second ball valve, the first ball valve and the second ball valve can be closed independently, and when the first ball valve and the second ball valve are separated, a large amount of oil leakage can be prevented.

[0007] A flange adapter pipe is connected between the first ball valve and the second ball valve. Two clamps are slidably connected to the flange adapter pipe via sliding parts. The two clamps fit around the joint between the second ball valve and the flange adapter pipe to ensure a sealed connection between the first ball valve and the second ball valve and prevent oil leakage.

[0008] A synchronization mechanism, wherein two synchronization mechanisms are provided and are rotatably connected to the flange adapter pipe, and the clamp is rotatably connected to the synchronization mechanism;

[0009] The actuator is connected to two clamps. The actuator drives the two clamps to separate from the second ball valve and the flange adapter. Under the action of the synchronizing mechanism, the two clamps move simultaneously, ensuring that the second ball valve and the flange adapter separate quickly, and also facilitating the subsequent docking of the second ball valve and the flange adapter.

[0010] Furthermore, the first ball valve and the second ball valve are respectively connected to a first actuator and a second actuator. When the second ball valve is urgently separated from the flange transfer pipe, the first actuator and the second actuator automatically close the first ball valve and the second ball valve, which can prevent oil leakage in time.

[0011] Furthermore, the sliding element includes a slide rail and a slider, which are respectively connected to the flange adapter pipe and the clamp. When the clamp moves, the slide rail can improve the accuracy and increase the clamping accuracy of the second ball valve and the flange adapter pipe.

[0012] Furthermore, the synchronization mechanism includes a central rod with push-pull arms rotatably connected to both ends of the central rod. The push-pull arms are rotatably connected to the clamps, enabling the two clamps to move simultaneously. When the second ball valve and the flange adapter separate, it will not be stuck by one of the clamps.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the second ball valve and the flange adapter are quickly separated, the driver uses the fixed seat to push the two clamps to move horizontally. The two clamps move simultaneously under the action of the center rod and the push and pull, and no longer jam the connection between the second ball valve and the flange adapter. The second ball valve and the flange adapter are separated without any damage to the components. After the second ball valve and the flange adapter are connected, the two clamps are locked and can be quickly restored to use.

[0015] (2) The first actuator and the second actuator can automatically close the first ball valve and the second ball valve. After the second ball valve and the flange transfer pipe are separated, oil can be prevented from leaking out through the first ball valve and the second ball valve, reducing pollution and avoiding oil waste.

[0021] 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.

[0022] Example:

[0023] Please see Figure 1-4 This utility model provides a technical solution: a dock oil loading and unloading arm with a quick release device, including a support arm structure, on which a first ball valve 5 is installed, the first ball valve 5 is connected to a second ball valve 6, and the support arm structure controls the movement of the first ball valve 5 and the second ball valve 6.

[0024] The flange adapter pipe 9 is connected between the first ball valve 5 and the second ball valve 6. Two clamps 10 are slidably connected to the flange adapter pipe 9 by sliding parts. The sliding parts improve the movement accuracy and smoothness of the clamps 10 and reduce the likelihood of jamming. The two clamps 10 fit over the joint between the second ball valve 6 and the flange adapter pipe 9. The clamps 10 are arc-shaped, which can connect the second ball valve 6 and the flange adapter pipe 9 over a larger range, ensuring stable sealing and preventing oil leakage.

[0025] The synchronization mechanism is provided in two parts and is rotatably connected to the flange adapter pipe 9. The clamp 10 is rotatably connected to the synchronization mechanism. The synchronization mechanism ensures that the two clamps 10 move at the same time. When the second ball valve 6 and the flange adapter pipe 9 are separated, it ensures that the two clamps 10 are separated from the second ball valve 6 at the same time, and the second ball valve 6 is separated smoothly.

[0026] The actuator 14 is connected to two clamps 10. The actuator 14 drives the two clamps 10 to separate from the second ball valve 6 and the flange adapter 9. The actuator 14 automatically controls the movement of the clamps 10. In case of emergency, it can automatically separate the second ball valve 6 from the flange adapter 9.

[0027] In this embodiment, as Figure 1As shown, the support arm structure includes a column 1, an inner arm 2 rotatably connected to the column 1 via a hinge seat 4, an outer arm 3 rotatably connected to the inner arm 2, and an outer arm 3 connected to a first ball valve 5. The inner arm 2 and the outer arm 3 transport oil. When the first ball valve 5 is closed, oil leakage in the outer arm 3 can be prevented.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, the first ball valve 5 and the second ball valve 6 are respectively connected to the first actuator 7 and the second actuator 8. The first actuator 7 and the second actuator 8 can automatically control the opening and closing of the first ball valve 5 and the second ball valve 6. When the flange adapter pipe 9 is separated and the second ball valve 6 is separated, the first ball valve 5 and the second ball valve 6 are automatically closed.

[0029] In this embodiment, as Figure 3 and Figure 4 As shown, the sliding component includes a slide rail 12 and a slider 11. The slide rail 12 and the slider 11 are respectively connected to the flange adapter pipe 9 and the clamp 10. The slide rail 12 supports the clamp 10 through the slider 11, ensuring that the clamp 10 moves along the slide rail 12 when it moves, thus achieving precise linear movement of the clamp 10. When it is necessary to connect the second ball valve 6 and the flange adapter pipe 9, it is less likely to cause error problems.

[0030] In this embodiment, as Figure 4 As shown, the synchronization mechanism includes a central rod 13, with push-pull arms 16 rotatably connected to both ends of the central rod 13. The push-pull arms 16 are rotatably connected to the clamps 10. When the central rod 13 rotates, the two push-pull arms 16 rotate synchronously, and the clamps 10 connected to the push-pull arms 16 also move accordingly, ensuring that the movement of the two clamps 10 will not deviate.

[0031] In this embodiment, as Figure 4 As shown, the driver 14 is connected to fixed seats 15 at both ends, and the fixed seats 15 are connected to the clamp 10 to realize the fixed connection between the clamp 10 and the driver 14.

[0032] Specifically, during use, when it is necessary to separate the second ball valve 6 and the flange adapter 9, the first actuator 7 controls the first ball valve 5 to close, the second actuator 8 controls the second ball valve 6 to close, the driver 14 extends and controls the movement of the two clamps 10 through the fixed seat 15, and the push-pull arm 16 and the center rod 13 ensure that the two clamps 10 move synchronously. The clamps 10 move along the slide rail 12. When the two clamps 10 are separated from the second ball valve 6, the second ball valve 6 is smoothly separated from the flange adapter 9.

[0033] When it is necessary to reconnect the flange adapter 9 and the second ball valve 6, the connection points of the flange adapter 9 and the second ball valve 6 are aligned. The actuator 14 shortens and drives the two clamps 10 to move closer to each other. The clamps 10 lock the flange adapter 9 and the second ball valve 6 together, so that the loading and unloading arm can be put into use quickly without delaying oil transportation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
