The lifting seat 22 is used for adjusting the height of the ejector rod 23, and the ejector rod 23 is used for pressing the main shaft into the impeller shaft disc.
Specifically, as shown in fig. 3, the fixed chassis 11 is arranged along the axial direction, the fixed chassis 11 is composed of a flat steel 111 and channel steel 112, the channel steel 112 is welded on two sides of one end face of the flat steel 111, the channel steel 112 is used as a guide rail, and the channel steel 112 is fixed by screws.
As shown in fig. 4-5, the movable chassis 12 includes a fixed supporting frame 121, a connecting shaft 122 and rollers 123, the connecting shafts 122 are connected to two sides of the fixed supporting frame 121, the rollers 123 are connected to two ends of the connecting shaft 122, and a space between the corresponding rollers 123 on two sides is adapted to a space between two channel steels 112 on the fixed chassis 11, so that the rollers 123 are movably disposed on the guide rails. Preferably, the roller 123 employs a T-shaped single-sided rail wheel.
More specifically, the fixing support 121 is formed by folding a steel plate into a plate structure with a V-shaped plate with a cross section as a center and two L-shaped plates at two ends, wherein the bending angle of the V-shaped plate is 140 °. Preferably, a 3mm steel plate is hemmed. Wherein, the roller 123 is located inside the L-shaped board structure to protect the roller 123. The V-shaped plate is structurally matched with the circular impeller, so that the impeller can be conveniently carried.
