[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0022] The utility model is a special tool for disassembling the pump shaft of a long shaft deep well pump. Figure 1 As shown ( Figure 2 、 Figure 3 、 Figure 4 The tool comprises an upper clamping device 1, a rotary transmission disc 2, a hydraulic drive 3 and a lower clamping device 4. The exploded view of the tool is shown in FIG. Figure 6 shown.

[0023] like Figure 5 As shown, the hydraulic drive 3 includes a fixed plate 32 and a rotating plate 31 driven by hydraulic pressure. The fixed plate 32 is fastened to the lower clamping device 4, and the rotating plate 31 is fastened to the upper clamping device 1 through the rotating transmission plate 2.

[0024] like Figure 7 As shown, the hydraulic drive 3 is connected to the mobile hydraulic station 6 through a dedicated oil pipe 5.

[0025] Further, such as Figure 7 As shown, the oil supply and discharge ports of the hydraulic driver 3 are connected to the oil supply and discharge ports of the mobile hydraulic station 6 through dedicated oil pipes 5.

[0026] Further, such as Figure 1 As shown, three upper fastening claws 11 are provided on the upper clamping device 1 for clamping the pump shaft 7 , and a claw adjustment hole is provided on one side of the upper clamping device 1 .

[0027] Further, such as Figure 1 As shown, three lower fastening claws 41 are provided on the lower clamping device 4 for clamping the coupling of the pump shaft 7, and a claw adjustment hole is provided on one side of the lower clamping device 4.

[0028] Furthermore, the hydraulic driver 3 and the upper clamping device 1 and the lower clamping device 4 are fastened with bolts and nuts.

[0029] Specific usage of this utility model:
