DETAILED DESCRIPTION

[0015] The utility model will be described in detail in connection with the drawings:

[0016] As Figure 1 And 2As shown, a multi-stage pump middle section dismounting tool, including base 1, base 1 is provided with the baffle 2 that is vertically arranged, the length direction of baffle 2 one end is fixed with the first connecting rod 3 that is horizontally arranged and is perpendicular to baffle 2, the other end is fixed with the second connecting rod 4 that is arranged with the first connecting rod 3 and is located the same plane and is mutually parallel, the first connecting rod 3 away from baffle 2 one end is detachably connected with the first clamping rod 5, specifically, the first connecting rod 3 away from baffle 2 one end is provided with the first screw hole 6, the first clamping rod 5 is provided with the first through hole 7, the first screw hole 6 is provided with the first bolt 8, the first bolt 8 passes through the first through hole 7, that is, the installation of first clamping rod 5 is completed by bolt, the first clamping rod 5 is provided with a plurality of first clamping holes 9 along the first clamping rod length 5 direction, when using, the limiting block of multi-stage pump middle section can be placed into the first clamping hole 9, so that the first clamping rod 5 can exert external force on the multi-stage pump middle section, the second connecting rod 4 away from baffle 2 one end is detachably connected with the second clamping rod 10, similarly, the second connecting rod 4 away from baffle 2 one end is provided with the second screw hole 11, the second clamping rod 10 is provided with the second through hole 12, the second screw hole 11 is provided with the second bolt 13, the second bolt 13 passes through the second through hole 12, the second clamping rod 10 is provided with a plurality of second clamping holes 14 corresponding to the first clamping hole 9 along the second clamping rod length 10 direction, since every multi-stage pump middle section has two limiting blocks, and the second clamping hole 14 corresponding to the first clamping hole 9 can be used to dismount one multi-stage pump middle section, the middle part of baffle 2 is provided with the jack 15 that is arranged with the first connecting rod 3 and is mutually parallel, through the jack 15, external force can be exerted on the pump shaft of multi-stage pump, thereby completing the dismounting of multi-stage pump middle section.

[0017] The bottom of the base 1 is provided with a plurality of supporting pads 16, which are used to adjust the height of the base 1, thereby facilitating the co-axial state of the jack 15 and the pump shaft of the multi-stage pump during dismounting.

[0018] The use mode of the utility model is as follows:

[0019] In use, first prevent base 1 from one side of multi-stage pump, then according to the height of base 1, place corresponding number of support pads 16 at the bottom of base 1, so that the jack 15 is consistent with the pump shaft of multi-stage pump and is coaxial, then extend the jack 15, so that one end of the jack 15 abuts against the end of the pump shaft of multi-stage pump, then install the first clamping rod 5 and the second clamping rod 10, when installing, the limit blocks at the ends of multiple multi-stage pumps can be placed into multiple first clamping holes 9 of the first clamping rod 5, then the first bolt 8 is installed into the first screw hole 6 through the first through hole 7, then the second clamping rod 10 is installed in the same way, after installation, the jack 15 is extended to apply external force to the pump shaft of multi-stage pump, because the middle section of multi-stage pump is limited by the first clamping rod 5 and the second clamping rod 10, the middle section of multi-stage pump can move relative to the pump shaft of multi-stage pump, so that the middle section of multi-stage pump is detached from the pump shaft of multi-stage pump, the disassembly is completed, using the tool, multiple middle sections of multi-stage pump can be disassembled on one side, the efficiency is greatly improved, and the installation mode of the first clamping rod 5 and the second clamping rod 10 is simple and convenient, without the need to install the jack on the base, the use mode is convenient and fast.
