A fixture for strain strengthening of small cryogenic containers

Abstract

This utility model discloses a fixing device for strain strengthening of small cryogenic containers, comprising an operating platform with a ladder on one side; several bases spaced apart from each other at the bottom of the operating platform, the top of each base being inclined; and several annular plates disposed between two of the bases. Compared to a pit-type fixing device, this device is movable without damaging the ground and is convenient for operation and observation; compared to a horizontal saddle-type fixing device, this structure has a smaller contact area with the inner container, thus less restricting plastic deformation during the strain strengthening process of the container.

Description

Technical Field

[0001] This utility model relates to the field of cryogenic container fixing technology, and in particular to a fixing device for strain strengthening of small cryogenic containers. Background Technology

[0002] With the sustained and rapid development of the national economy and the continuous improvement of industrialization, the market demand for gases is increasing. Cryogenic liquefied gas transportation has experienced rapid development due to its advantages of low cost, convenience, high product purity, and easy liquid-gas conversion. The maturity of strain-intensified manufacturing technology, which can significantly increase the design pressure of containers or reduce the design wall thickness, has brought new opportunities and challenges to the cryogenic container industry. Small cryogenic containers, in particular, are favored by many small gas-consuming plants due to their convenience and miniaturization. Therefore, the securing of small cryogenic containers during the strain-intensified manufacturing process is especially important; safe, convenient, reliable, and quick securing devices can save manufacturing time and costs. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned technical problems and provide a fixing device for strain strengthening of small cryogenic containers.

[0004] The technical solution of this utility model: a fixing device for strain strengthening of small cryogenic containers, comprising:

[0005] The operating platform has an escalator on one side;

[0006] Several bases are arranged at intervals at the bottom of the operating platform, and the top of each base is a slope.

[0007] Several annular plates are disposed between the two bases.

[0008] Preferably, the upper surface of the operating platform is patterned.

[0009] Preferably, the operating platform is equipped with guardrails.

[0010] Preferably, the operating platform is equipped with a protective ring.

[0011] Preferably, the base is provided with a rubber pad.

[0012] The beneficial effects of this utility model are as follows: Compared with the pit-type fixing device, this device is movable without damaging the ground and is convenient to operate and observe; compared with the horizontal saddle-type fixing device, this structure has a smaller contact area with the inner container, less restriction on plastic deformation during the strain strengthening process of the container, and this device can be moved during hoisting.

[0016] 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.

[0017] Reference Figures 1 to 2 A fixture for strain strengthening of small cryogenic containers, comprising:

[0018] The operating platform 10 has an escalator 101 on one side;

[0019] Several bases 2 are arranged at intervals at the bottom of the operating platform 10, and the top of each base 2 is a slope.

[0020] Several annular plates 3 are disposed between two bases 2. In this invention, the cryogenic container is hoisted into the device, and the bottom of the cryogenic container contacts the base 2 for support. Workers can climb onto the operating platform 10 via the ladder 101. The annular plates 3 improve the connection strength between the bases 2. The device is movable without damaging the ground, is convenient for operation and observation, and has a smaller contact area with the container, thus reducing the restriction on plastic deformation during the strain strengthening process of the container.

[0021] As a preferred embodiment of this utility model, it may also have the following additional technical features:

[0022] In this embodiment, the upper surface of the operating platform 10 is patterned to effectively prevent people from slipping.

[0023] In this embodiment, the operating platform 10 is equipped with a guardrail 102, which can effectively prevent personnel from falling from the operating platform 10.

[0024] In this embodiment, the operating platform 10 is provided with a protective ring 103. This is used to protect the small cryogenic container from tilting due to improper hoisting. The protective ring 103 has a gap with the cryogenic container and does not have direct contact, which is beneficial to the overall plastic deformation of the container during strain strengthening.

[0025] In this embodiment, a rubber pad 201 is provided on the base 2. This pad is used to prevent impact during hoisting.

[0026] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0027] 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.
