[0032] The following will further describe the present utility model in detail through specific embodiments in conjunction with the drawings.

[0033] See Figure 1 As shown, this embodiment provides a disassembly device for the thrust bearing of a vertical pump, including a jacking rod 100, a limiting plate 200, and multiple suspension rods 300; a threaded hole 210 is provided on the limiting plate 200, and the jacking rod 100 is threadedly connected in the threaded hole 210; a connecting through hole 220 is provided on the limiting plate 200, the suspension rod 300 is inserted into the connecting through hole 220, and the maximum outer diameter of the suspension rod 300 is greater than the diameter of the connecting through hole 220. The end with a smaller outer diameter of the suspension rod 300 is connected to the thrust bearing 500.

[0034] Specifically, during use, the suspension rod 300 is inserted into the connecting through hole 220 of the limiting plate 200, and one end of the suspension rod 300 is installed on the thrust bearing 500. Then, the user rotates the jacking rod 100, and one end of the jacking rod abuts against the end of the pump shaft 400. Continuously rotating the jacking rod 100 can cause the jacking rod 100 to drive the limiting plate 200 to move upward, so that the limiting plate 200 drives multiple suspension rods 300 to move upward, thereby moving the thrust bearing 500 upward to complete the disassembly work, which is convenient for the staff to operate.

[0035] See Figure 1 As shown, a connecting through hole 220 is provided on the limiting plate 200. The end with a smaller outer diameter of the suspension rod 300 is inserted into the connecting through hole 220, and the end with a larger outer diameter of the suspension rod 300 abuts against the top surface of the limiting plate 200.

[0036] One end of the suspension rod 300 is provided with an external thread, and a threaded connection hole adapted to the suspension rod 300 is provided on the thrust bearing 500. Thus, the suspension rod 300 can be connected to the thrust bearing 500, facilitating the upward movement of the thrust bearing 500 when the suspension rod 300 moves upward.

[0037] The jacking rod 100 is a bolt. In addition, those skilled in the art can select the structure of the jacking rod 100 according to actual needs, which will not be elaborated here.

[0038] SeeFigure 1 As shown in the figure, in an alternative solution of this embodiment, one end of the suspension rod 300 is provided with a blocking convex ring 310, and the maximum outer diameter of the blocking convex ring 310 is greater than the diameter of the connecting through hole 220.

[0039] Specifically, a blocking convex ring 310 is provided at one end of the suspension rod 300, and the blocking convex ring 310 is located above the limiting plate 200. When the user rotates the jacking rod 100 to jack it open, one end of the jacking rod 100 abuts against the pump shaft 400, so that the rotation of the jacking rod 100 drives the limiting plate 200 to move up and down, so that the limiting plate 200 can drive the blocking convex ring 310 to rise, the blocking convex ring 310 drives the suspension rod 300 to rise synchronously, and the suspension rod 300 can drive the thrust bearing 500 to rise.

[0040] Among them, a plurality of connecting through holes 220 are symmetrically arranged on the limiting plate 200 with the threaded hole 210 as the symmetry center. Through such a setting, when the limiting plate 200 drives multiple suspension rods 300 to rise, the external forces applied by the multiple suspension rods 300 to the limiting plate 200 are balanced, so that the limiting plate 200 can rise smoothly.

[0041] Among them, the number of the connecting through holes 220 is two, and the two connecting through holes 220 are symmetrically arranged with the threaded hole 210 as the symmetry center.

[0042] Among them, the number of the connecting through holes 220 is four, and the four connecting through holes 220 are evenly distributed along the circumferential direction of the threaded hole 210.

[0043] Preferably, the connecting through holes 220 are evenly distributed along the circumferential direction of the threaded hole 210.

[0044] In addition, those skilled in the art can set the number of the connecting through holes 220 according to actual needs, which will not be elaborated here.

[0045] See Figure 1 As shown in the figure, in an alternative solution of this embodiment, a connecting seat 110 is provided at one end of the jacking rod 100, and a labor-saving through hole 120 is provided on the connecting seat 110.

[0046] Specifically, a connecting seat 110 is provided at one end of the jacking rod 100, and a labor-saving through hole 120 is provided on the connecting seat 110. A driving rod is inserted into the labor-saving through hole 120, and the user can rotate the jacking rod 100 labor-savingly through the driving rod for the convenience of the user's operation.

[0047] Among them, the driving rod can be a smooth rod, and retaining pins are inserted at both ends of the driving rod, so that the driving rod will not fall off after being inserted into the labor-saving through hole 120 on the connecting seat 110 for the convenience of the user's operation.

[0048] In an alternative solution of this embodiment, a flexible pad is provided at the end of the jacking rod 100 that contacts the pump shaft 400.

[0049] Specifically, a flexible pad is provided at one end of the ejector rod 100 in contact with the pump shaft 400 to avoid adverse effects of the ejector rod 100 on the pump shaft 400.

[0050] Among them, those skilled in the art can select the material of the flexible pad according to actual needs, and details will not be elaborated here.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
