[0002] The shell and tube heat exchanger is mainly composed of a shell, a tube sheet, heat exchange tubes, a head, a baffle, etc. The two ends of the tube bundle of the heat exchanger pass through two tube sheets respectively, and a number of baffles are vertically mounted in the middle of the tube bundle. In actual production, the outer circle of the tube sheet is always much larger than the outer circle of the baffle. In the process of manufacturing the tube bundle, the baffle needs to be supported so that the tube holes of the baffle and the tube holes of the tube sheet are at the same horizontal position, and the tube sheet and the baffle are both in a vertical state. The existing support device is only a support, and the verticality of the baffle and the concentricity with the tube sheet are not reasonably and effectively positioned, which leads to the jamming of the heat exchange tube and the difficulty of tube threading. The support device needs to be artificially raised to facilitate tube threading, which causes a lot of inconvenience in actual production and affects work efficiency. Summary of the invention
