Description

Technical Field

[0001] This utility model relates to the field of tank base technology, specifically a base for a fixed cryogenic storage tank. Background Technology

[0002] Storage tanks are sealed containers used to store liquids, gases (especially cryogenic media), and other materials. Their core function is to safely contain the medium and maintain its required physical state (such as cryogenic temperature), ensuring the stability of material storage and use. The base is the bottom support component of the storage tank, and its core function is to enhance the tank's stability on the ground.

[0003] In the prior art, utility model patent application number CN202320091650.6 discloses a light hydrocarbon storage tank base, including a support frame and two brackets. The bottom of the support frame is equipped with casters, and multiple arc-shaped support plates are fixed on the brackets. Flexible pads are provided on the support plates. This utility model, by setting arc-shaped support plates and providing flexible pads on them, on the one hand, increases the contact area between the light hydrocarbon storage tank and the flexible pads through the cooperation of the support plates and the flexible pads, providing better support for the light hydrocarbon storage tank. On the other hand, the flexible pads can effectively reduce the vibration of the light hydrocarbon storage tank, avoiding damage to the tank. Simultaneously, it avoids direct contact between the support plates and the light hydrocarbon storage tank, preventing friction and ensuring good safety.

[0004] The aforementioned patent provides a base for fixing storage tanks. However, existing bases are mainly used for fixing large storage tanks, and their function is relatively simple, only providing stability. For some storage tanks with a volume of less than 1 cubic meter, due to the small size of the tank, it is impossible to install accessories on the tank. Therefore, the base cannot assist in the installation of accessories and needs further improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a base for a fixed cryogenic storage tank, aiming to improve the existing bases for small cryogenic storage tanks with a volume of less than 1 cubic meter. These bases only have a single function, ensuring ground stability, and lack sufficient space to assist in the installation of external accessories such as vaporizers and supporting pipelines.

[0006] This utility model is implemented as follows:

[0007] A base for a fixed cryogenic storage tank includes a frame body, which has a tank cavity and an accessory cavity. Side protective frames are symmetrically arranged on both sides of the frame body, a support base is provided at the bottom, and lifting rings are evenly distributed at the four corners of the upper end. A lead screw shaft is rotatably installed in each of the side protective frames on both sides, and the lead screw shafts on both sides rotate synchronously. A fixed bracket is fixedly installed at one end of the tank cavity, and a movable bracket is adjustable at the other end through the lead screw shaft.

[0008] Preferably, the frame body includes several steel pipes and rectangular plates. The frame body is composed of several steel pipes and rectangular plates forming a rectangular frame with an open top. The rectangular frame is provided with partitions to divide it into a tank cavity and an accessory cavity. The side protection frame is integrally constructed and set on both sides of the frame body.

[0009] Preferably, the support bases are symmetrically arranged on both sides of the bottom of the frame body, and the height of the support bases is greater than 10cm.

[0010] Preferably, each of the four upper corners of the frame body is fixedly provided with a screw hole seat, and the lifting eye is threadedly installed on the screw hole seat.

[0011] Preferably, it also includes a linkage shaft, the two ends of which are rotatably mounted on the side protective frames on both sides, and the shaft is disposed through the accessory cavity, and the lead screw shafts on both sides are connected to the linkage shaft for transmission.

[0012] Preferably, the linkage shaft further includes a rotating handle, and one end of the linkage shaft extends to the outside of the side protective frame and is provided with a rotating handle.

[0013] Preferably, a first bevel gear is provided at one end of the lead screw shaft near the linkage shaft, and a second bevel gear that meshes with the first bevel gear is provided on the linkage shaft.

[0014] Preferably, it also includes a protective housing, wherein the interior of the accessory cavity is provided with a protective housing that covers the linkage shaft.

[0016] Preferably, it also includes sliding rods, with multiple sliding rods provided in both sides of the side protective frame, and sliding sleeves corresponding to each sliding rod provided on the side of the movable card seat, the sliding sleeves being slidably mounted on the sliding rods.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model addresses the pain point of small cryogenic storage tanks with a volume of less than 1 cubic meter being unable to externally install vaporizers, supporting pipelines, and other accessories by dividing the main frame into a tank cavity and an accessory cavity. The tank cavity focuses on fixing the storage tank, while the accessory cavity provides dedicated installation space for external equipment, avoiding collision damage or pipeline clutter caused by exposed accessories. This achieves integrated design of the storage tank and supporting components, ensuring the safety of cryogenic medium storage and improving the neatness of the equipment layout, thus adapting to the special usage scenarios of small storage tanks.

[0019] 2. This utility model uses a linkage shaft in conjunction with a bevel gear transmission to achieve synchronous rotation of the lead screw shafts on both sides, which drives the movable bracket to accurately approach or move away from the fixed bracket, and can flexibly adapt to small cryogenic storage tanks of different diameters.

[0020] 3. The threaded lifting rings at the four corners of the upper part of the frame body of this utility model facilitate the overall hoisting and transportation of the equipment, and the detachable design does not affect daily use; the support base with a bottom height of more than 10cm facilitates forklift movement and improves the flexibility of equipment transfer. The side protection frame is integrally constructed with the frame body, enhancing the overall structural strength and providing protection for the sides of the tank. Attached Figure Description

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0029] Example 1

[0030] like Figures 1-4 As shown, a base for a fixed cryogenic storage tank includes a frame body 1. The frame body 1 has a tank cavity 101 and an accessory cavity 102. Side protective frames 2 are symmetrically arranged on both sides of the frame body 1, a support base 3 is provided at the bottom, and lifting rings 5 ​​are evenly distributed at the four corners of the upper end. The frame body 1 includes several steel pipes and rectangular plates. The steel pipes are square hollow steel pipes, which are welded to form the frame body 1. The frame body 1 is formed by several steel pipes and rectangular plates to form a rectangular frame with an open upper end. The rectangular frame is provided with a partition to divide it into the tank cavity 101 and the accessory cavity 102. The side protective frames 2 are integrally constructed and arranged on both sides of the frame body 1. Support bases 3 are symmetrically arranged on both sides of the bottom of the frame body 1. The height of the support bases 3 is greater than 10cm, which facilitates the user's movement using a forklift or overhead crane. During movement, the tank cavity 101 stores the storage tank, and the accessory cavity 102 is mainly used to store electrical components. Therefore, the weight at one end of the tank cavity 101 is greater than that at the other end of the accessory cavity 102. The forklift can lift the tank cavity 101 by lifting it from one end, thus achieving stable lifting and ensuring that the frame body 1 will not shift. Screw holes 103 are fixedly installed at the four corners of the upper end of the frame body 1. The lifting rings 5 ​​are threaded onto the screw holes 103. The threaded installation of the lifting rings 5 ​​onto the screw holes 103 not only facilitates disassembly but also allows the operator to easily control the fixing angle of the lifting rings 5. Furthermore, turning the thread in or out by one turn will not affect the normal use of the lifting rings 5.

[0031] like Figure 1 , Figure 3 and Figure 5As shown, each of the two side protective frames 2 is rotatably equipped with a lead screw shaft 4, which rotates synchronously. A fixed retainer 8 is fixedly installed at one end inside the tank cavity 101, and a movable retainer 9 is adjustable at the other end via the lead screw shaft 4. The movable retainer 9 includes a threaded sleeve 902, with threaded sleeves 902 on both sides corresponding to each lead screw shaft 4, and the threaded sleeves 902 are threaded onto the corresponding lead screw shaft 4. Additionally, a linkage shaft 7 is included, with both ends rotatably mounted on the two side protective frames 2, and the shaft extending through the accessory cavity 102. Both lead screw shafts 4 on both sides are connected to the linkage shaft 7. The linkage shaft 7 also includes a rotating handle 702, with one end extending to the outside of the side protective frame 2. A first bevel gear 401 is located at the end of the lead screw shaft 4 near the linkage shaft 7, and a second bevel gear 701 meshing with the first bevel gear 401 is located on the linkage shaft 7. Additionally, a protective housing 6 is included, with the accessory cavity 102 housing a protective housing 6 that encloses the linkage shaft 7. The lead screw shaft 4 uses a Tr40×6 left-hand trapezoidal thread with a thread helix angle of approximately 3.4° (less than the equivalent friction angle between steels, which is 15°-20°), possessing natural self-locking properties and preventing axial movement due to the tank's weight or vibration when no external force is applied. Furthermore, sliding rods 10 are included; multiple sliding rods 10 are installed in the side protective frames 2 on both sides. The movable mounting base 9 has sliding sleeves 901 on its side, corresponding to each sliding rod 10, which are slidably mounted on the sliding rods 10. By manually operating the handle 702, the lead screw shafts 4 on both sides can be rotated synchronously, thereby moving the movable mounting base 9 closer to or further away from the fixed mounting base 8, thus clamping and securing the tank. The operation is simple. The slide rod 10 is made of 45# steel, with a diameter of 25mm and a length of 1450mm. Both ends are welded and fixed to the side protection frame 2, and it is in clearance fit with the slide sleeve 901 (clearance 0.2mm). It is coated with lubricating oil to reduce sliding resistance and extend service life.
