Abstract
The invention discloses an auxiliary device for installation of an inner tube of a heat exchanger. The auxiliary device comprises an object stage and a supporting frame. The carrying plate is used for placing the inner tube. The object stage is provided with a rolling mechanism. When the inner tube moves axially, the inner tube is in rolling contact with the object stage through the rolling mechanism. The supporting frame supports the object stage. The supporting frame is provided with a lifting mechanism which is used for adjusting the height of the object stage. The base of the supporting frame is provided with rollers for walking. By using the auxiliary device provided by the invention for installing the inner tube of the heat exchanger, since the inner tube is in rolling contact with the object stage through the rolling mechanism, when the inner tube moves axially, the friction between the inner tube and the object stage is rolling friction, the rolling friction is smaller, the inner tube can be manually pushed into installation holes in tube plates by an operator, the installation of the inner tube can be realized without needing the cooperation of an insertion car and a joist barrow and the installation process is simplified.
