Description

Technical Field

[0001] The utility model relates to the manufacturing field of pressure vessel assembly technology, in particular to a slideway type supporting device for internal parts of variable diameter equipment. Background Art

[0002] There are two types of heat exchanger internals (or pipe system) and shell sets: non-fixed diameter and variable diameter. The non-fixed diameter form is more common. For the non-fixed diameter set, the usual practice is to use a crane to lift it into the cylinder and then drag it. For the variable diameter cylinder set, especially when the diameter of the variable diameter cylinder is large and the length is long, the crane cannot be sent into the internal track.

[0003] At present, the structural form of the horizontal installation of ordinary cylinders is: two support tubes are arranged in the cylinder for horizontal transportation and installation of equipment, which are usually composed of pipes and steel sections. The steel sections play a stabilizing role and the two support tubes play a sliding role. However, for variable diameter cylinders, the tubular guide rails can only provide support when the internal parts are at the corresponding position. The sliding effect of large-diameter cylinders on the support rails is poor, and the transition problem on large-diameter cylinders cannot be solved. In particular, when the large-diameter cylinder is too long, during the delivery process, the large-diameter cylinder and the two support tubes are gradually increased and cannot move forward. For this reason, we propose a slideway support device for the installation of internal parts of variable-diameter equipment. Utility Model Content

[0004] The purpose of the utility model is to provide a slideway type supporting device for the internal parts set of variable diameter equipment to solve the above-mentioned shortcomings in the technology.

[0006] Preferably, the inner wall of one end of the sleeve shell is fixedly provided with positioning columns distributed at equal distances, and is connected with the large-diameter cylinder through the positioning columns, so as to facilitate the positioning of the large-diameter cylinder.

[0007] Preferably, the inner wall of the expansion tube is fixedly provided with positioning brackets which are distributed at equal distances by welding, one end of the positioning bracket is welded with a positioning plate, and the outer wall of the positioning plate is provided with two positioning holes.

[0009] Preferably, two support plates are fixedly provided on the outer wall of the bottom of the sleeve shell and the expansion tube, respectively, so that the utility model can be placed at a designated position conveniently through the support plates.
