[0012] In one embodiment, the moving part includes a base plate and a plurality of pulleys; the base plate is disposed above the transport track; the plurality of pulleys are rotatably disposed on the base plate and roll along the transport track.
[0013] In one embodiment, the surface of the load-bearing part is covered with an anti-slip mat; and / or, a plurality of limiting baffles are provided at the top of the load-bearing part, the plurality of limiting baffles being used to block each side of the cooling device to fix the cooling device.
[0014] In one embodiment, the support portion includes a reinforcing rib and a support rod; the reinforcing rib is disposed on the inner sidewall of the housing; the support rod is disposed on the reinforcing rib and extends downward to fix the second mating portion.
[0015] In one embodiment, a sealing ring is provided between the end cap and the tower body.
[0016] The technical solution of this utility model is to set an opening in the main body of the tower and set a first guide rail.

[0028] The cold box is one of the key pieces of equipment in air separation equipment. It belongs to the cryogenic separation unit. Air separation units utilize the different physical properties of various components in the air and use methods such as deep freezing, adsorption, and membrane separation to separate oxygen, nitrogen, argon, and the expensive "golden gases" krypton and xenon from the air. At the same time, it produces some liquid oxygen, liquid nitrogen, and liquid argon products. At present, my country is vigorously developing its manufacturing industry, involving electronic chip manufacturing, liquid crystal display device manufacturing, petrochemical, food manufacturing, automobile manufacturing, aerospace and other manufacturing industries. However, due to factors such as manufacturing difficulty and transportation conditions, cold boxes are often assembled on-site, which is difficult to assemble and has a long construction period.
[0029] In related technologies, cold box towers include a tower body and a refrigeration unit. The tower body provides support and protection, while the refrigeration unit is installed inside the tower body. During installation, the tower body is first erected around its perimeter, then the refrigeration unit is hoisted into the tower body, and finally the tower body is capped. The hoisting weight is large and difficult to control, and the refrigeration unit is at risk of damage during the hoisting process, requiring high strength from the refrigeration unit.
[0030] Based on this, this utility model proposes a cold box tower installation system 100. Please refer to [link / reference]. Figures 1 to 2 ,
[0031] In one embodiment of this utility model, the cold box tower installation system 100 includes a tower body 1, a transport component 2, a cooling device 3, and an end cap 4; the tower body 1 has an opening 11 end, and an opening 11 is provided at the opening 11 end; a first guide rail 12 extending in the front-rear direction is provided inside the tower body 1; the transport component 2 includes a base 21, a second guide rail 22, and a carrier 23; the base 21 is disposed outside the tower body 1 and located at the opening 11 end; the second guide rail 22 is disposed on the base 21 and extends in the front-rear direction. The second guide rail 22 is detachably connected to the first guide rail 12. When the second guide rail 22 is connected to the first guide rail 12, the second guide rail 22 and the first guide rail 12 are connected to form a transport track. The carrier 23 is movably arranged on the transport track. The cooling device 3 is placed on the carrier 23 and moves along the transport track from the outside to the inside of the tower body 1 under the drive of the carrier 23. When the second guide rail 22 and the first guide rail 12 are disassembled to move away from each other, the end cover 4 is placed on the opening 11.
[0032] The technical solution of this utility model is to set an opening 11 and a first guide rail 12 in the main body 1 of the tower. When the cooling device 3 is installed, the installation and transportation component 2 drives the cooling device 3 to move from the outside to the inside along the transportation guide rail composed of the first guide rail 12 and the second guide rail 22 until the carrier 23 drives the cooling device 3 to the installation position inside the main body 1 of the tower. Then the installation is carried out. After installation, the transportation component 2 is disassembled and the end cover 4 is finally installed to achieve rapid installation. During the installation process, there is no need to hoist the cooling device 3, which reduces the construction difficulty and shortens the installation period.
[0033] Please refer to the following: Figure 3 and Figure 4In one embodiment of this utility model, the first guide rail 12 includes an unloading section 121 facing away from the opening 11. Along a direction away from the second guide rail 22, the unloading section 121 is inclined downwards. In the unloading section 121, the carrier 23 drives the cooling device 3 to move downwards. The cold box tower installation system 100 also includes an assembly component 5, which includes a support part 51, a first mating part 52, and a second mating part 53. The support part 51 is disposed on the inner side wall of the tower body 1. The first mating part 52 is fixedly disposed on the support part 51, located above the unloading section 121. The second mating part 53 is fixedly disposed above the cooling device 3. The second mating part 53 cooperates with the first mating part 52. When the carrier 23 drives the cooling device 3 to move to the unloading section 121, the second mating part 53 cooperates with the first mating part 52, causing the cooling device 3 to separate from the carrier 23 and fixing the cooling device 3 to the support part 51.
[0034] Thus, the carrier 23 drives the cooling device 3 from the outside of the tower body 1 along the transport track to the inside, and then to the unloading section 121. The carrier 23 drives the cooling device 3 to move downward along the unloading section 121. During the downward movement, the first mating part 52 and the second mating part 53 cooperate to separate the cooling device 3 from the carrier 23 and fix the cooling device 3 to the support part 51. The arrangement of the transport track and the carrier 23 enables the cooling device 3 to move into the tower body 1. The arrangement of the unloading section 121 and the assembly component 5 enables the cooling device 3 to separate from the carrier 23 when it reaches a certain position, thus realizing convenient unloading and installation.
[0035] Furthermore, the first mating part 52 and the second mating part 53 have mutually engaging grooves and protrusions on their respective end faces. The protrusions are inserted into the grooves when the carrier 23 moves the cooling device 3 to the unloading section 121. In this way, the precise fit between the protrusions and grooves ensures that the cooling device 3 is firmly fixed, avoiding shaking and deviation during installation, improving installation accuracy and safety. This design simplifies the operation steps, reduces manpower requirements, further shortens the overall installation time, and optimizes work efficiency.
[0036] Because the cold box operates at a low temperature, to prevent the protrusion from deforming and elongating within the groove due to temperature changes, thus affecting the movement of the cooling device 3, in one embodiment of this invention, the depth of the groove is H, and the length of the protrusion is L, where 1.2L ≤ H ≤ 1.5L. In this way, after the protrusion is inserted into the groove, there is still sufficient space to accommodate minor deformations caused by temperature changes, ensuring the cooling device 3 is stably fixed and does not affect its movement or installation.
[0037] In one embodiment of this invention, the cross-sectional area of the protrusion gradually decreases along the direction close to the second mating part 53. This arrangement allows the protrusion to be inserted into the groove more smoothly, reducing frictional resistance while maintaining a tight fit. This ensures that the cooling device 3 remains stable under temperature fluctuations, further improving installation efficiency and safety.
[0038] In one embodiment of this utility model, the carrier 23 includes a movable part 231 and a load-bearing part 232; the movable part 231 contacts the transport track and moves along the transport track; the load-bearing part 232 is detachably disposed above the movable part 231 for placing the cooling device 3. Thus, after the cooling device 3 is installed, the load-bearing part 232 can be quickly disassembled to prevent the carrier 23 from getting stuck on the transport track.
[0039] In one embodiment of this utility model, the moving part 231 includes a base plate 231A and a plurality of pulleys 231B; the base plate 231A is disposed above the transport track; the plurality of pulleys 231B are rotatably disposed on the base plate 231A and roll along the transport track. Thus, the pulley 231B design reduces friction, ensuring smooth movement of the carrier 23. The synergistic effect of the base plate 231A and the pulleys 231B improves the flexibility and stability of the carrier 23 on the transport track, further optimizing the transportation and installation process of the cooling device 3.
[0040] Furthermore, multiple pulleys 231B are elastically connected to the base plate 231A. After the cooling device 3 is installed, the moving part 231 can automatically retract, and the spacing of the pulleys 231B is adjusted to ensure that the carrier 23 can smoothly leave the track, avoid jamming, improve the ease of operation, further shorten the installation time, and optimize the overall work efficiency.
[0041] In one embodiment of this utility model, an anti-slip pad is laid on the surface of the load-bearing part 232. This arrangement, with its slip-resistant material, effectively increases the friction between the cooling device 3 and the load-bearing part 232, preventing the cooling device 3 from sliding during movement and ensuring safety and stability.
[0042] In one embodiment of this utility model, a plurality of limiting baffles 233 are provided at the top of the load-bearing part 232. The multiple limiting baffles 233 are used to block the sides of the cooling device 3 to fix the cooling device 3. With this arrangement, the limiting baffles 233 effectively prevent the cooling device 3 from shifting during transportation, ensuring that it is stably placed on the load-bearing part 232, and further improving the stability and safety of the installation process.
[0043] In one embodiment of this utility model, the support portion 51 includes a reinforcing rib 511 and a support rod 512; the reinforcing rib 511 is disposed on the inner sidewall of the outer shell; the support rod 512 is disposed on the reinforcing rib 511 and extends downward to fix the second mating portion 53. This arrangement ensures a tight connection between the support rod 512 and the reinforcing rib 511, enhancing the overall rigidity of the outer shell, ensuring the stability of the second mating portion 53 under high temperature and high pressure conditions, further improving the durability and reliability of the cooling device 3, and optimizing the overall structural safety.
[0044] In one embodiment of this utility model, a sealing ring is provided between the end cap 4 and the tower body 1. This arrangement ensures that the end cap 4 and the tower body 1 fit tightly together, preventing leakage of the cooling medium, improving sealing performance, ensuring cooling effect, extending equipment service life, and further enhancing the overall stability and safety of the cooling device 3.
[0045] The installation steps for installing an air separation cold box using the cold box tower installation system 100 are as follows:
[0046] Step 1: Construct the main body of the tower;
[0047] Step 2: Install base 21 and second guide rail 22 in sequence;
[0048] The third step is to place the carrier 23 on the second guide rail 22, place the cooling device 3 on the carrier 23, and push the carrier 23 to the unloading section 121. The carrier 23 tilts downward in the unloading section 121, and the first mating part 52 and the second mating part 53 automatically dock to complete the precise positioning of the cooling device 3.
[0049] Step 4: Disassemble the load-bearing part 232 and the moving part 231, and take out the moving part 231 and the load-bearing part 232 in sequence.
[0050] Step 5: Disassemble and install the base 21, the second guide rail 22 and the carrier 23, and install the end cover 4.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
