Description

Technical Field

[0001] This utility model relates to the field of loading arm technology, and in particular to a double-sealed oil depot loading arm. Background Technology

[0002] An loading arm is a specialized piece of equipment used for loading and unloading liquid materials (such as petroleum, chemicals, and liquefied natural gas). It is typically installed between storage and transportation facilities such as tanks, tank trucks, and ships. Its main body usually consists of a rotary joint, piping, balancing device, and control mechanism, enabling flexible rotation and precise positioning to meet loading and unloading requirements at different heights and angles. Based on application scenarios, loading arms are divided into land-based and marine types. They feature strong sealing, high safety, and convenient operation, and are widely used in industries such as petrochemicals, metallurgy, and ports, serving as a key piece of equipment in liquid material loading and unloading systems.

[0003] When existing loading arms are connected to tank trucks, the relative displacement between the loading arms and the tank truck opening is easily caused by vibration and shaking during the oil transfer process. This causes the connection between the loading arms and the tank truck to deviate, resulting in a reduced sealing effect at the connection point. This can easily lead to oil and gas leaks and pose a great safety hazard.

[0004] Therefore, we propose a double-sealed oil depot loading arm to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-sealed oil depot loading arm includes a loading arm support, on the output end of which a loading arm body is fixedly installed. A sealing ring and a clamping base are fixedly fitted on the loading arm body. The clamping base has a clamping chamber inside and multiple flip-out openings on the outside of the clamping base, all of which are connected to the same clamping chamber.

[0007] Specifically, a sealing rubber block is fixedly fitted on the outer side of the loading arm body, which can weaken and buffer the vibration and shaking generated during oil transportation, and prevent the loading arm body from colliding with the inner wall of the tank opening.

[0008] Specifically, the same sealing sleeve is fixedly fitted on the outer side of both the sealing rubber block and the main body of the loading arm, and there is a gap between the inner wall of the sealing sleeve and the sealing rubber block.

[0009] Specifically, a fixed post is fixedly installed on the inner side of each of the multiple flip-out ports, and a flip-out metal strip is rotatably sleeved on each of the multiple fixed posts. The flip-out metal strip can be limited so that it can only flip around the fixed post as the center.

[0010] Specifically, two guide posts are fixedly installed on the inner side of the clamping chamber, and the same linkage ring is slidably sleeved on both guide posts. The bottom of the linkage ring extends out to form a clamping base, and an annular groove is formed on the outer side of the linkage ring.

[0011] Specifically, each of the multiple flip metal strips has a fixed linkage base on one side, each of the multiple linkage bases has a linkage groove on one side, each of the multiple linkage grooves has a fixed linkage column on the inside, each of the multiple linkage columns has a rotatable linkage metal block, and each of the multiple linkage metal blocks is slidably installed inside the same annular groove, so that the multiple linkage metal blocks can be moved by the linkage ring.

[0012] Specifically, clips are fixedly installed on one side of each of the multiple flip metal strips, and anti-slip pads are fixedly installed on one side of each of the multiple clips to increase the tightness of the connection.

[0013] Specifically, a return spring is fixedly installed on the top inner wall of the clamping chamber, and the other end of the return spring is fixedly connected to the top of the linkage ring to facilitate the reset of the linkage ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the multiple clamps can clamp the tank opening of the oil tanker, preventing relative displacement between the loading arm and the tank opening of the oil tanker due to vibration, shaking and other reasons during oil transportation, so as to keep the loading arm and the oil tanker firmly connected, ensure the smooth operation of oil loading and unloading, avoid the reduction of the sealing effect at the connection and the occurrence of oil and gas leakage, and increase the practicality and safety of the equipment.

[0021] Reference Figure 1-5 A double-sealed oil depot loading arm includes a loading arm support 1, a loading arm body 2 fixedly installed on the output end of the loading arm support 1, a sealing rubber ring 3 and a clamping base 6 fixedly sleeved on the loading arm body 2; the clamping base 6 has a clamping chamber inside, and multiple flip-out openings are opened on the outside of the clamping base 6, and the multiple flip-out openings are all connected to the same clamping chamber.

[0022] In this embodiment, a sealing rubber block 5 is fixedly sleeved on the outside of the loading arm body 2, which can weaken and buffer the vibration and shaking generated during the oil transportation process, and prevent the loading arm body 2 from colliding with the inner wall of the tank opening.

[0023] In this embodiment, the same sealing rubber sleeve 4 is fixedly fitted on the outer side of both the sealing rubber block 5 and the loading arm body 2, and there is a gap between the inner wall of the sealing rubber sleeve 4 and the sealing rubber block 5.

[0024] In this embodiment, a fixing post 7 is fixedly installed on the inner side of each of the multiple flip-out ports, and a flip metal strip 8 is rotatably sleeved on each of the multiple fixing posts 7. The flip metal strip 8 can be limited so that it can only flip around the fixing post 7 as the center.

[0025] In this embodiment, two guide posts 13 are fixedly installed on the inner side of the clamping chamber. The same linkage ring 14 is slidably sleeved on both guide posts 13. The bottom of the linkage ring 14 extends out to the clamping base 6 and contacts the tank opening of the oil tanker. When the loading arm body 2 is connected to the tank opening of the oil tanker, the tank opening squeezes the linkage ring 14, thereby causing the linkage ring 14 to move. An annular groove is provided on the outer side of the linkage ring 14.

[0026] In this embodiment, a linkage base 9 is fixedly installed on one side of each of the multiple flip metal strips 8, a linkage groove is opened on one side of each of the multiple linkage bases 9, a linkage column 10 is fixedly installed on the inner side of each of the multiple linkage grooves, a linkage metal block 11 is rotatably sleeved on each of the multiple linkage columns 10, and the multiple linkage metal blocks 11 are slidably installed on the inner side of the same annular groove, so as to facilitate the movement of the multiple linkage metal blocks 11 by the linkage ring 14.

[0027] In this embodiment, a clip 12 is fixedly installed on one side of each of the multiple flip metal strips 8, and an anti-slip pad is fixedly installed on one side of each of the multiple clips 12. The multiple clips 12 are in contact with the same tank opening of the oil tanker, which makes it easier for the multiple clips 12 to clamp the tank opening of the oil tanker and can increase the tightness of the connection.

[0028] In this embodiment, a reset spring 15 is fixedly installed on the top inner wall of the clamping chamber, and the other end of the reset spring 15 is fixedly connected to the top of the linkage ring 14, so as to facilitate the reset of the linkage ring 14.

[0029] Working Principle: During oil transfer, the operator moves the loading arm body 2 directly above the tanker opening. Then, the loading arm body 2 descends into the tank opening, and the sealing sleeve 4 and sealing rubber block 5 enter the opening. The sealing sleeve 4 expands and contracts elastically, adhering tightly to the inner wall of the tank opening to accommodate dimensional deviations and form a flexible sealing layer. Simultaneously, the sealing rubber block 5 provides support to the sealing sleeve 4 and, being a block structure, weakens and buffers vibrations and swaying during oil transfer, preventing collisions between the loading arm body 2 and the inner wall of the tank opening. The sealing ring 3, when the loading arm connects to the tank opening, fills the annular gap through compression deformation, preventing oil, gas, or liquid leakage from the interface. The sealing ring 3 achieves a static seal by filling the annular gap between the loading arm body 2 and the tank opening, while the sealing sleeve 4 flexibly fills the inner side of the tank opening, working with the sealing rubber block 5 to fill local gaps for dynamic compensation sealing. This achieves a double sealing effect, preventing oil and gas leakage. 2. When the arm moves downward, the linkage ring 14 comes into contact with the tank opening. At this time, the linkage ring 14 is squeezed and moves. An annular groove is provided on the outer side of the linkage ring 14. The movement of the linkage ring 14 causes the annular groove to move upward, which in turn causes multiple linkage metal blocks 11 to move. The movement of multiple linkage metal blocks 11 causes the corresponding linkage column 10 to move. The movement of multiple linkage column 10 causes the corresponding linkage base 9 to move. The movement of multiple linkage base 9 causes the corresponding flipping metal strip 8 to move. However, multiple flipping metal strips 8 are all rotated and sleeved on the corresponding fixed column 7. Therefore, multiple flipping metal strips 8 can only flip around the corresponding fixed column 7 as the center. The flipping of multiple flipping metal strips 8 causes the corresponding clamp 12 to clamp the tank opening of the oil tanker, thereby increasing the tightness of the connection and preventing relative displacement between the arm body 2 and the tank opening of the oil tanker due to vibration, shaking and other reasons during the oil transportation process, ensuring the smooth progress of oil loading and unloading operations. When the arm body 2 is lifted away from the tank opening, the return spring 15 pulls the linkage ring 14 upward, causing multiple clamps 12 to release the tank opening and achieve quick unlocking.

[0030] The technological advancement of this invention compared to the prior art is that the multiple clamps 12 can hold the tank opening of the oil tanker, preventing relative displacement between the loading arm body 2 and the tank opening of the oil tanker due to vibration, shaking, or other reasons during oil transportation. This ensures a stable connection between the loading arm body 2 and the oil tanker, guaranteeing smooth loading and unloading operations, preventing reduced sealing at the connection point and potential oil and gas leaks, and increasing the practicality and safety of the equipment.
