Description

Technical Field

[0001] This utility model relates to the field of marine loading and unloading arm sealing technology, and in particular to an ERC clamp locking and sealing mechanism. Background Technology

[0002] Marine loading arms are specialized devices used at port terminals to dock with ships for loading and unloading liquids. The ERS (Emergency Release System) is a crucial component ensuring the safe operation of the loading arm. It automatically or manually cuts off the medium and quickly separates the loading arm from the ship in emergencies to prevent media leakage and accidents. The emergency release clamp device ensures the upper and lower ball valves are connected without loosening or gaps. A seal exists between the upper and lower ball valves; loosening can lead to cross-sectional leakage. In more serious cases, if the clamp fails during loading and unloading, causing accidental opening and separation of the upper and lower ball valves, a large amount of medium will leak onto the ship or into the sea, causing incalculable losses and environmental pollution. Utility Model Content

[0003] The technical problem this invention aims to solve is that the tightness of the emergency release clamp cannot be adjusted when it becomes loose, resulting in limited safety and adaptability.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an ERC clamp locking and sealing mechanism, including a clamp body, the clamp body being composed of a first clamp, a second clamp and a third clamp, an adjusting screw being provided between the first clamp and the second clamp, between the second clamp and the third clamp and the third clamp, and between the third clamp and the first clamp, an adjusting oil cylinder being provided on the outside of the first clamp, and the inner side of the first clamp, the second clamp and the third clamp being a trapezoidal wedge surface.

[0005] Mounting brackets are provided on both sides of the outer surfaces of the first clamp, the second clamp, and the third clamp.

[0006] The two ends of the adjusting screw between the second clamp and the third clamp are respectively movably connected to the mounting bracket.

[0007] A lateral mounting frame is movably mounted on the mounting bracket near the third clamp end of the first clamp, and a lateral adjustment frame is movably mounted on the mounting bracket near the second clamp end of the first clamp.

[0008] The cylinder body of the regulating cylinder is connected to the regulating screw on the second clamp via a lateral adjusting frame.

[0009] The two ends of the lateral mounting frame are respectively connected to the adjusting screw on the third clamp and the extended end of the adjusting cylinder.

[0010] The beneficial effects of this utility model are:

[0011] (1) The ERC clamp locking and sealing mechanism of this utility model is provided with adjusting screws between the first clamp, the second clamp and the third clamp, which can adjust the clamping force of the clamp;

[0012] (2) The inner side of the first clamp, the second clamp and the third clamp is a trapezoidal wedge surface, which can fit tightly against the double ball valve assembly surface to improve friction and sealing.

[0013] (3) The design of three adjusting screws reduces the transmission path of the locking force along the circumferential direction, which significantly improves the sealing effect;

[0014] (4) The newly improved design of the three adjusting screws allows for precise control of the preload of each screw using a torque wrench, thereby ensuring uniform force on the sealing surface of the double ball valve;

[0015] (5) The newly improved design of the three adjusting screws shortens the length of the clamp, making the clamp's application of locking force on the wedge surface of the double ball valve more concentrated and effective. Attached Figure Description

[0020] 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.

[0021] 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.

[0022] Figure 1 , Figure 2 and Figure 3The ERC clamp locking and sealing mechanism shown includes a clamp body, which is composed of a first clamp 1, a second clamp 2, and a third clamp 3. Adjusting screws 4 are provided between the first clamp 1 and the second clamp 2, between the second clamp 2 and the third clamp 3, and between the third clamp 3 and the first clamp 1. An adjusting cylinder 5 is provided on the outside of the first clamp 1. The inner sides of the first clamp 1, the second clamp 2, and the third clamp 3 are all trapezoidal wedge surfaces. After the double ball valve assembly is installed, the middle is also a trapezoidal wedge surface. The inner sides of clamp 2 and the third clamp 3 are secured to the wedge surfaces between the double ball valves via wedge surfaces. The clamps are then tightened by the adjusting screw 4 between the first clamp 1 and the third clamp 3, so that all clamps tightly hold the double ball valves. However, because the outer diameter of the entire clamp is large, the friction between the clamp wedge surfaces and the double ball valve wedge surfaces is also large. The pre-tightening force obtained by the original adjusting screw 4 is far from sufficient. Therefore, evenly spaced adjusting screws 4 are used in conjunction with adjusting cylinder 5 to ensure a tight fit between the clamps and the valve body, and the force applied in one circle is also more even.

[0023] Mounting brackets 6 are provided on both sides of the outer side of the first clamp 1, the second clamp 2, and the third clamp 3.

[0024] The adjusting screw 4 between the second clamp 2 and the third clamp 3 is movably connected to the mounting bracket 6 at both ends.

[0025] A lateral mounting frame 7 is movably mounted on the mounting bracket 6 at the end of the first clamp 1 near the end of the third clamp 3, and a lateral adjustment frame 8 is movably mounted on the mounting bracket 6 at the end of the first clamp 1 near the end of the second clamp 2.

[0026] The cylinder body section of the adjusting cylinder 5 is connected to the adjusting screw 4 on the second clamp 2 via the lateral adjusting frame 8.

[0027] The two ends of the lateral mounting frame 7 are respectively connected to the adjusting screw 4 on the third clamp 3 and the extended end of the adjusting cylinder 5.

[0028] 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.
