[0034] The adjusting mechanism 40 is arranged on the adsorption bracket 10 and has a plurality of adjusting ends penetrating through the adsorption bracket 10 and the heat preservation box 20. The adjusting mechanism 40 is used to adjust the position of the heating mechanism 30 in the adjusting cavity so that the heating end of the heating mechanism 30 abuts against the weld of the large vertical equipment.

[0035] Compared with the prior art, the fixing device for the vertical seam heat treatment heating belt 33 provided by this embodiment is provided with an adsorption bracket 10, which can be detachably connected to the large vertical equipment. A heat preservation box 20 is provided, and the heating mechanism 30 can be carried through the adjusting cavity. The heating mechanism 30 can be slidably arranged in the adjusting cavity and always abuts its heating end against the weld of the large vertical equipment. An adjusting mechanism 40 is provided. The position of the heating mechanism 30 in the adjusting cavity can be adjusted so that the heating end of the heating mechanism 30 abuts against the weld of the large vertical equipment, which can make the heating belt 33 closely fit the tank body, with good adaptability and practicability.

[0036] In some embodiments, the above-mentioned adsorption bracket 10 can adopt structures such as Figure 1 , Figure 2 as shown. Referring to Figure 1 , Figure 2 , the adsorption bracket 10 includes: a connecting frame 11, adsorption units 12, and a control switch. The connecting frame 11 is fixedly connected to the insulation box 20. A plurality of adsorption units 12 are provided, and each adsorption unit 12 is disposed on the connecting frame 11. Each adsorption unit 12 abuts against the large vertical equipment and is used for adsorbing on the side wall of the large vertical equipment. The control switch is used to control the start and stop of each adsorption unit 12.

[0037] The connecting frame 11 can be fixedly connected to the insulation box 20. The adsorption units 12 on the connecting frame 11 can adsorb on the side wall of the large vertical equipment, so that the heating end of the heating mechanism 30 abuts against the weld of the large vertical equipment. The control switch can control the start and stop of each adsorption unit 12.

[0038] In some embodiments, the above-mentioned adsorption unit 12 can adopt structures such as Figure 1 , Figure 2 as shown. Referring to Figure 1 , Figure 2 , the adsorption unit 12 is an electromagnet.

[0039] An electromagnet is a device that uses an electric current passing through its coil to generate a magnetic field, which can attract or repel magnetic materials. When an electric current passes through the coil, a magnetic field will be generated around the coil. If there is an iron core inside the coil, this magnetic field will magnetize the iron core, thereby enhancing the magnetic field strength of the entire system. Electromagnets are prior art and will not be elaborated here.

[0040] In some embodiments, the above-mentioned heating mechanism 30 can adopt structures such as Figure 3 as shown. Referring to Figure 3 , the heating mechanism 30 includes: a sliding plate 31, a heat preservation plate 32, and a heating tape 33. The sliding plate 31 is slidably disposed in the adjustment cavity. One end of the heat preservation plate 32 is connected to the sliding plate 31 and slides with the sliding plate 31. One end of the heating tape 33 is connected to the other end of the heat preservation plate 32 and slides synchronously with the sliding plate 31 and the heat preservation plate 32, so that the other end of the heating tape 33 abuts against the side wall of the large vertical equipment.

[0041] The sliding plate 31 can be slidably disposed in the adjustment cavity and slides driven by the adjustment mechanism 40. The heat preservation plate 32 is connected to one side of the sliding plate 31 and can slide with the sliding plate 31. The heating tape 33 is connected to the other side of the heat preservation plate 32 and can slide synchronously with the sliding plate 31 and the heat preservation plate 32. The heating tape 33 can abut against the weld of the large vertical equipment.

[0042] It should be noted that the heating tape 33 is an electric heating device used to provide a stable heat source. The heating tape 33 is mainly composed of an electrothermal material (usually a nickel-chromium alloy tape) and an insulating material (such as multi-layer alkali-free glass fiber). The electrothermal material is responsible for generating heat, while the insulating material ensures safety in use and prevents current leakage. The heating tape 33 is an existing technology and will not be elaborated here.

[0043] In some embodiments, the above-mentioned heat preservation board 32 can adopt a structure as Figure 3 shown. Refer to Figure 3 , the heat preservation board 32 is made of aluminosilicate.

[0044] Aluminosilicate is a multi-functional inorganic compound with wide application value and excellent physical and chemical properties. Aluminosilicate is a composite silicon-aluminum oxide compound composed of aluminum oxide (Al2O3) and silicon dioxide (SiO2), with low thermal conductivity, excellent thermal stability and chemical stability. Aluminosilicate is an existing technology and will not be elaborated here.

[0045] In some embodiments, the above-mentioned adjusting mechanism 40 can adopt a structure as Figures 1 to 3 shown. Refer to Figures 1 to 3 , the adjusting mechanism 40 includes a plurality of adjusting lead screws 41. One end of each adjusting lead screw 41 penetrates through the adsorption bracket 10 and the heat preservation box 20 and abuts against the sliding plate 31, so that the sliding plate 31, the heat preservation board 32 and the heating tape 33 slide in the adjusting cavity. The penetrating end of the adjusting lead screw 41 is the adjusting end.

[0046] The adjusting lead screw 41 can penetrate through the adsorption bracket 10 and the heat preservation box 20 and abut against the sliding plate 31. By rotating the adjusting lead screw 41, the sliding plate 31, the heat preservation board 32 and the heating tape 33 slide in the adjusting cavity, so that the heating tape 33 abuts against the weld of the large vertical equipment.

[0047] In some embodiments, the above-mentioned adjusting lead screw 41 can adopt a structure as Figures 1 to 3 shown. Refer to Figures 1 to 3 , a handle 411 is provided at the other end of each adjusting lead screw 41. The handle 411 is used to facilitate the rotation of the adjusting lead screw 41.
