Description

Technical Field

[0001] The utility model relates to the technical field of tank containers, in particular to a high-strength conch-shaped head structure for tank containers. Background Art

[0002] Semicircular fiberglass reinforced plastic is a composite reinforcing material with excellent comprehensive properties such as light weight, high strength, corrosion resistance, and impact resistance. It is usually used as an anti-corrosion material. In recent years, due to its advantages such as beauty, safety, and convenient installation, the semicircular fiberglass reinforced plastic head has been increasingly used in tank containers.

[0003] With the increasingly wide range of applications of tank containers, customers have more and more functional requirements for them, such as the pressure and temperature inside the tank. However, the commonly used heads at present only meet the requirements of strength and appearance, and generally can only meet the use requirements of tank containers with a diameter less than 2.5m, and cannot meet the use needs of large multi-functional tank containers with a diameter greater than 2.5m, even exceeding 3m. In addition, at present, each specification of tank container is equipped with a corresponding head, which inevitably requires the production of various specifications of heads to adapt to different specifications of tank containers, bringing certain difficulties to the production process and also being inconvenient for later classification management. Therefore, the above problems need to be solved urgently. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a high-strength conch-shaped head structure for tank containers, which adopts the combination of a head body and an airbag, and the head body is tightly pressed and fitted against the port of the tank container through an electric push rod, thereby improving the sealing performance.

[0005] To solve the above technical problem, the utility model adopts the following technical solutions: A high-strength conch-shaped head structure for tank containers of the utility model is characterized in that: it includes a head body, a connecting component and an airbag; a head body matching with it is coaxially sleeved on the right end face of the horizontally and transversely arranged tank container, the head body is a horizontally and transversely arranged hollow cylindrical structure, and its outer diameter is larger than the outer diameter of the tank container; a circular groove matching with the outer diameter of the tank container is coaxially embedded and opened on the left outer side of the head body, the circular groove is communicated with the inside of the head body, and the right inner side of the head body is tightly pressed and fitted against the right end face of the tank container through the circular groove, and is fixedly connected with the tank container through the connecting component, thereby blocking the tank container; an airbag is also coaxially sleeved between the inside of the head body and the tank container, and the airbag is tightly pressed and fitted against the inside of the head body and the outer circumferential surface of the tank container respectively through inflation, thereby performing secondary blocking on the port of the tank container.

[0006] Preferably, a fixing plate matching with the head body is coaxially sleeved and fixed on the left outer side of the head body relative to the outside of the circular groove. The fixing plate is an open-ended circular ring structure at both ends. The inner diameter of the fixing plate is larger than the diameter of the circular groove, and its outer diameter is smaller than the outer diameter of the head body.

[0007] Preferably, the connecting component includes an electric push rod and an arc-shaped plate. At the middle position of the outer circumferential surface of the fixing plate, several electric push rods are evenly spaced and vertically arranged along the circumferential direction. Each electric push rod is arranged along the radial direction of the fixing plate, and its tail part is screwed and fixed to the corresponding position of the outer circumferential surface of the fixing plate respectively. The pushing end of each electric push rod extends radially into the interior of the fixing plate along the radial direction of the tank container, and is respectively screwed and fixed to the middle position of the outer arc surface of the corresponding arc-shaped plate, and drives the corresponding arc-shaped plate to reciprocate radially relative to the outside of the tank container. Each arc-shaped plate matches with the tank container and is coaxially arranged with the tank container. Therefore, under the drive of the electric push rod, each arc-shaped plate is respectively in tight contact with the corresponding position of the outer circumferential surface of the tank container to tightly fix the head body.

[0008] Preferably, it further includes a rib plate. A rib plate is horizontally and vertically fixed between the tail part of each electric push rod and the left side surface of the head body to respectively fix and strengthen the corresponding electric push rod through the rib plate.

[0009] Preferably, anti-slip protrusions are fixedly attached to the inner arc surface of each arc-shaped plate to ensure the stability of the tight contact between the arc-shaped plate and the tank container through the anti-slip protrusions.

[0010] Preferably, lifting lugs are vertically and symmetrically fixed on the front and rear sides of the outer circumferential surface of the head body near its top. The two lifting lugs do not interfere with the fixing action of the connecting component, and thus the head body is lifted through the lifting lugs.

[0011] Preferably, it further includes arc panel Ⅰ, arc panel Ⅱ, arc panel Ⅲ and arc panel Ⅳ. Arc panel Ⅰ, arc panel Ⅱ, arc panel Ⅲ and arc panel Ⅳ are fixedly attached coaxially in sequence from left to right on the right side surface of the head body. Arc panel Ⅰ, arc panel Ⅱ, arc panel Ⅲ and arc panel Ⅳ are gradually and smoothly transitioned in sections from the edge of the head body to the center direction, and their diameters gradually decrease, so as to form a conch shape on the right side surface of the head body to reinforce and strengthen the head body.

[0012] Preferably, the outer diameter of the circular groove is 3.5 m, and the adjacent center distances between arc panel Ⅰ, arc panel Ⅱ, arc panel Ⅲ and arc panel Ⅳ are all 20 cm.
