[0022] Embodiment 2:
[0023] As Figure 3 shown in the figure, on the basis of the bearing device for the heat exchanger tube sheet described in Embodiment 1, the device further includes two limit blocks 5. The cross-section of the placement table 4 is approximately "T"-shaped. The placement table 4 includes a vertical support plate 41 and a placement plate 42 horizontally arranged at one end of the support plate 41. The rubber gasket 3 is arranged between the bottom of the support plate 41 and the placement groove 2. The two limit blocks 5 are respectively arranged in the gaps formed between the placement plates 42 on both sides of the lower part of the support plate 41 and the placement groove 2 to limit the horizontal position of the placement plate 42 through the limit blocks 5 on both sides of the lower part of the placement table 4.
[0024] Furthermore, a first groove 21 matching the number of rubber gaskets 3 is provided at the bottom of the placement groove 2. The rubber gasket 3 is arranged in the first groove 21 and the thickness of the rubber gasket 3 is higher than the depth of the first groove 21. By providing the first groove 21, the rubber gasket 3 is prevented from sliding due to accidental factors.
[0025] Furthermore, a cylindrical hole 6 is horizontally and penetratingly provided in the clamping plate 1, the placement table 4 and the limit blocks 5, and a rope can pass through the cylindrical hole 6, so as to achieve the purpose of convenient transportation.
[0026] Furthermore, the clamping plate 1, the placement table 4 and the limit blocks 5 are all made of high-hardness materials to ensure the overall load-bearing performance of the device, and the tube sheet is not easily deformed when placed thereon.

[0028] Under the working conditions of this embodiment, the requirements for placing the heat exchanger tube sheet are relatively strict, and it is necessary to ensure that the tube sheet is placed horizontally. Therefore, by setting the limit block 5, the horizontal position of the placing plate 42 on the placing table 4 is further fixed. Moreover, the clamping plate 1, the placing table 4, and the limit block 5 are all made of high-hardness materials, so that when the tube sheet is placed on the placing table 4, it is not easy to tilt. At the same time, a first groove 21 for placing the rubber gasket 3 is also provided, so that the rubber gasket 3 is not easy to slide. Cylindrical holes 6 are horizontally penetrated through the clamping plate 1, the placing table 4, and the limit block 5, which is convenient for transporting the device. A second groove 43 is also provided on the placing table 4, and a preheating device can be installed therein to preheat the tube sheet, thereby improving the thermal efficiency when the tube sheet is put into use. In addition, the clamping plate 1, the placing table 4, and the limit block 5 in this embodiment can also be made of hard metal materials to ensure the overall load-bearing performance of the device and prevent the tube sheet from deforming when placed thereon.
