[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] like Figure 1-2 As shown, an impeller main shaft installation tool includes a mounting base 1 and a column assembly 2 that cooperate with each other. The mounting base 1 is located on one side of the column assembly 2. The mounting base 1 is used to realize the forward and backward movement of the impeller, and the column assembly 2 is used to press the main shaft into the impeller shaft disk.

[0030] Among them, the mounting base 1 is composed of a fixed chassis 11 and a movable chassis 12. The movable chassis 12 carries the impeller, and the movable chassis 12 can move forward and backward on the fixed chassis 11. The forward and backward movement of the impeller is realized by the forward and backward movement of the movable chassis 12 on the fixed chassis 11.

[0031] The column assembly 2 includes a column 21, a lifting seat 22 and a push rod 23. The lifting seat 22 can be vertically lifted on the column 21. The push rod 23 is fixed on the lifting seat 22 and arranged axially along the column 21. The lifting seat 22 is used to adjust the height of the push rod 23, and the push rod 23 is used to press the main shaft into the impeller shaft disc.

[0032] Specifically, Figure 3 As shown, the fixed chassis 11 is arranged along the axial direction, and is composed of a flat steel 111 and a channel steel 112. Channel steel 112 is welded on both sides of one end surface of the flat steel 111. The channel steel 112 is used as a guide rail and is fixed by screws.

[0033] like Figure 4-5 As shown, the mobile chassis 12 includes a fixed support frame 121, a connecting shaft 122 and a roller 123. The connecting shaft 122 is connected to both sides of the fixed support frame 121. Both ends of the connecting shaft 122 are connected to rollers 123. The spacing between the corresponding rollers 123 on both sides is adapted to the spacing between the two channel steels 112 on the fixed chassis 11, so that the rollers 123 can be movably arranged on the guide rail. Preferably, the rollers 123 are T-shaped single-sided track wheels.

[0034] More specifically, the fixed support frame 121 is formed by folding a steel plate into a plate structure with a cross section of a V-shaped plate in the center and L-shaped plates at both ends, wherein the bending angle of the V-shaped plate is 140°. Preferably, a 3mm steel plate is used for folding. The roller 123 is located inside the L-shaped plate structure to protect the roller 123. The V-shaped plate structure is adapted to the circular impeller, which is convenient for carrying the impeller.

[0035] In addition, a reinforcing rib 124 is provided at the bottom of the V-shaped plate. The reinforcing rib 124 is formed by two channel steels, which are respectively located at two ends of the bottom surface of the V-shaped plate. The function of the reinforcing rib 124 is to increase the strength of the fixed support frame 121.

[0036] like Figure 6 As shown, combined with Figure 1-2 In the column assembly 2, the column 21 includes a bottom mounting plate 211 and a vertical seat 212. The bottom mounting plate 211 is evenly provided with a plurality of screw holes, and the column 21 is fixed to the working surface by screws penetrating the screw holes; a lifting seat 22 is installed on the vertical seat 212, and a strip hole 213 for avoiding the lifting seat 22 is vertically provided on one side of the vertical seat 212 facing the lifting seat 22 (see Figure 7 ) to meet the lifting and lowering of the lifting seat 22 on the vertical seat 212.

[0037] The lifting seat 22 includes a lifting plate 221 . A lifting block (not shown) is disposed on one side of the lifting plate 221 facing the vertical seat 212 . The lifting block passes through the strip hole 213 and extends into the vertical seat 212 .

[0038] like Figure 8 As shown, the lifting seat 22 has a bearing 223, and the lifting seat 22 is connected to the column 21 through the bearing 223. Specifically, the lifting plate 221 is provided with connecting plates 222 on both sides of one end surface facing the vertical seat 212, and the connecting plate 222 is rotatably connected with the bearing 223, and the bearing 223 is in contact with the side of the vertical seat 212, so that when the lifting seat 22 is lifted and lowered on the vertical seat 212, the bearing 223 acts to reduce the friction coefficient during the movement, thereby improving the lifting stability of the lifting seat 22.

[0039] like Fig. 9 As shown, the push rod 23 is composed of a seamless tube 231 and an end plate 232. The end plate 232 is provided with a plurality of mounting holes along its circumference, and the end surface of the lifting plate 221 is provided with connecting holes matching the mounting holes. The end plate 232 is fixed to the lifting seat 22 by fastening screws in conjunction with the mounting holes and the connecting holes, and the spindle is inserted into the seamless tube 231 to be pressed in.

[0040] Back to Figure 1-2 , and combined with Figure 6The column assembly 2 also includes a lifting screw 24, which penetrates into the vertical seat 212 and is connected to the lifting block screw nut pair on the lifting seat 22, and a hand wheel 25 is connected to the top of the lifting screw 24. By turning the hand wheel 25, the lifting screw 24 is driven to rotate. Since the lifting seat 22 itself does not rotate, the rotation of the lifting screw 24 drives the lifting seat 22 to rise and fall along the height direction of the vertical seat 212. The top rod 23 is fixed on the lifting seat 22, and the lifting seat 22 is raised and lowered to drive the top rod 23 to rise and fall. By adjusting the height of the top rod 23, the installation of spindles of different heights can be adapted to improve the applicable range of the installation tool.

[0041] The specific implementation principle of the utility model is: when installing the impeller spindle, the impeller is placed on the mobile chassis 12, the spindle is placed on the push rod 23, the hand wheel 25 is turned to adjust the height of the lifting seat 22 to adjust the height of the push rod 23, so that the center axis of the spindle on the push rod 23 is consistent with the center axis of the impeller, and then the mobile chassis 12 is pushed in the direction of the spindle to move the impeller in the direction of the spindle until the spindle is pressed into the impeller shaft disc, and the installation is completed. The installation process is convenient and labor-saving, and effectively saves work time.

[0042] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
