Description

Technical Field

[0001] This utility model relates to the field of sealing control technology, and in particular to a quick-connect connector manual opening device. Background Technology

[0002] Marine loading arms are specialized devices used at port terminals for docking with ships to load and unload liquid media. The quick-connect device (QCDC) is a crucial component for enabling rapid docking between the loading arm and the ship. Before docking begins, the cover at the front of the quick-connect device must be removed, and after loading and unloading are completed, the cover must be replaced to prevent dust and moisture from entering the pipeline.

[0003] When the QCDC is not in use for loading or unloading, the blind flange is typically clamped with QCDC clamps to prevent dust and moisture from entering the pipeline. Currently, the blind flange is made of aluminum plate, and it needs to be removed and properly secured by on-site personnel before docking with the ship. Consequently, after loading and unloading operations are completed and the QCDC is separated from the ship, on-site personnel still need to reinstall the blind flange onto the QCDC. In summary, the previous conventional design was cumbersome for on-site loading and unloading operations and required consideration of storage and protection after removing the blind flange, reducing on-site production efficiency.

[0004] Blind flanges are independent components and require manual handling by on-site personnel. When large loading arms are in operation, and given the increased weight of the blind flanges, multiple people are needed to coordinate the work, increasing labor costs and posing safety hazards. After removal, on-site storage and protection measures must be considered to prevent damage that could affect the sealing performance. Utility Model Content

[0005] The technical problem this utility model aims to solve is that when a large loading and unloading arm is used for loading and unloading operations, multiple people are required to work together, which increases labor costs, reduces production efficiency, and poses safety hazards; it is also necessary to consider the on-site storage and protection of blind flanges.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a quick-connecting connector manual cover opening device, including a cover plate and a sealing flange that cooperates with the cover plate. A limit block is welded and fixed on one side of the sealing flange, and a support is welded and fixed on the other side of the sealing flange. A first connecting block is fixedly assembled on the end of the cover plate near the support. A second connecting block is welded and fixed on the cover plate at the position corresponding to the limit block. A guide sleeve is fixed on the outer end of the support. The cover plate is movably assembled with the support through a pin on the first connecting block through the guide sleeve. A guide shaft for locking the angle of the cover plate is fixedly assembled on the outer side of the pin.

[0007] A spring is sleeved on the outer side of the pin at the lower end of the first connecting block.

[0008] The guide sleeve has an arc-shaped transition opening that mates with the guide shaft, and the bottom surface of the arc-shaped transition opening has limiting grooves at both ends that mate with the guide shaft.

[0009] External positioning blind holes are provided at both the upper and lower ends of the limiting block.

[0010] The second connecting block has positioning balls that mate with external positioning blind holes on its inner top and bottom surfaces.

[0011] Both ends of the pin are axially fixed with top extrusion heads.

[0012] The beneficial effects of this utility model are:

[0013] (1) The quick-connecting connector manual opening device of this utility model consists of a hinge and a blind plate. The blind plate is manually rotated by the handle on the blind plate, which reduces the disassembly operation of on-site personnel and improves work efficiency.

[0014] (2) This opening device moves and stops by the movement of the pin and guide shaft in the guide sleeve, which improves the flipping limit capability and enhances the structural stability. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Figure 1 and Figure 2The quick-connecting connector manual opening device shown includes a cover plate 1 and a sealing flange 2 that mates with the cover plate 1. A limit block 3 is welded and fixed on one side of the sealing flange 2, and a support 4 is welded and fixed on the other side of the sealing flange 2. A first connecting block 5 is fixedly assembled on the end of the cover plate 1 near the support 4. A second connecting block 6 is welded and fixed on the cover plate 1 at the position corresponding to the limit block 3. A guide sleeve 7 is fixed on the outer end of the support 4. The cover plate 1 is movably assembled with the support 4 through the guide sleeve 7 via a pin 8 on the first connecting block 5. A guide shaft 9 for locking the angle of the cover plate 1 is fixedly assembled on the outer side of the pin 8.

[0021] A spring 10 is sleeved on the outer side of the pin 8 at the lower end of the first connecting block 5.

[0022] The guide sleeve 7 has an arc-shaped transition opening 11 that mates with the guide shaft 9. The bottom surface of the arc-shaped transition opening 11 has limiting grooves 12 that mate with the guide shaft 7 at both ends.

[0023] External positioning blind holes 13 are provided at both the upper and lower ends of the limiting block 3.

[0024] The second connecting block 6 has a positioning ball 14 that mates with the external positioning blind hole 13 on both its inner top and inner bottom surfaces.

[0025] Both ends of the pin 8 are axially fixed with top extrusion heads 15

[0026] This cover opening device has a recessed groove on the outer side of the cover plate 1. A handle is fixed inside the recessed groove for easy external control. The movement and stopping are achieved by the movement of the pin 8 and the guide shaft 9 within the guide sleeve 7. When rotation is required, the pin 8 is manually pulled to rotate the cover plate 1 to the open or closed state. When the spring 10 is released again, the guide shaft 9 automatically returns to the limiting slot 12 under the action of the spring force, restricting the rotation of the cover plate 1.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
