Specific implementation
[0016] The specific implementation of the utility model will be further explained below in combination with the drawings.
[0017] As Figures 1-5 shown, an impeller taking-out tool, including two sides open frame 4, one side of frame 4 is provided with side plate 5, and the both ends of side plate 5 are connected with the upper and lower ends of frame 4 through fixed plate 6 respectively, wherein the fixed plate 6 located at the top and the upper end of frame 4 are provided with through groove 7, the lower surface of this fixed plate 6 and the lower surface of the upper end of frame 4 are provided with sliding groove, and the inside of sliding groove is slidably connected with sliding plate 8, the upper end of sliding plate 8 is provided with handle 9, handle 9 can move along through groove 7, further including jack 10, jack 10 has input end and output end, the output end of jack 10 is fixedly connected with sliding plate 8, the lower end of jack 10 is provided with fixed rod 11, the lower end of frame 4 is provided with through hole 12, the both sides of through hole 12 are provided with side groove 13 penetrating through through hole 12 respectively, the inside of two side grooves 13 is slidably connected with clamping block 14 respectively, threaded hole 15 is formed in clamping block 14, bolt 16 is threadedly connected in threaded hole 15 of clamping block 14, and the both sides of frame 4 and one side of side plate 5 are provided with support leg 17 respectively.
[0018] The impeller 2 taken out by the tool should have a balance hole 20, two balance holes 20 are arranged on the impeller 2, the impeller 2 is provided with a mounting groove matched with the pump shaft 3, the balance holes 20 are symmetrically arranged on both sides of the mounting groove, some balance holes 20 have internal threads, and some balance holes 20 are smooth holes, so it is necessary to first open threads in the balance holes 20, and then use the tool to take out the impeller 2 in the pump body 1.
[0019] When the impeller 2 is taken out, first, the pump body 1 is placed vertically on the ground with the impeller 2 upward, then the frame 4 in the tool is placed above the pump body 1, and the center hole on the frame 4 is aligned with the pump shaft 3 upward and downward, at this time, there is a certain gap between the lower end of the frame 4 and the pump body 1, so that the supporting leg 17 can be placed on the ground and support the frame 4, after the tool is placed, the sliding plate 8 is moved along the sliding groove by the handle 9, the jack 10 is moved from the inside of the frame 4 to the position close to the side plate 5, and the upper part of the center hole is fully exposed, so that the worker can operate in the inside of the frame 4, after the jack 10 is moved out, the clamping block 14 is moved, the bolt 16 in the clamping block 14 is aligned with the balance hole 20 on the impeller 2, and then the bolt 16 is screwed with the balance hole 20, when the two bolts 16 are respectively screwed with the two balance holes 20, the jack 10 is moved by the handle 9, and the fixed rod 11 at the bottom of the jack 10 is aligned with the center hole, when the fixed rod 11 is aligned with the center hole, the jack 10 stops moving, then the output end of the jack 10 is controlled by the input end of the jack 10 to extend out, when the output end of the jack 10 extends out, the fixed rod 11 at the bottom of the jack 10 moves downward, and the fixed rod 11 passes through the center hole and abuts against the pump shaft 3, when the fixed rod 11 contacts the pump shaft 3, the bottom of the jack 10 cannot continue to move downward, and with the continuous extension of the output end of the jack 10, the frame 4 is moved upward, when the frame 4 moves upward, the lower impeller 2 is also moved upward, so that the impeller 2 is pulled out from the pump shaft 3, after the impeller 2 is separated from the pump shaft 3, the tool is directly removed from the pump body 1 together with the impeller 2.
[0020] The outer diameter of the fixed rod 11 is smaller than the inner diameter of the center hole, and the outer diameter of the fixed rod 11 is also smaller than the outer diameter of the pump shaft 3, so that the fixed rod 11 can pass through the center hole and abut against the pump shaft 3, and at the same time, the fixed rod 11 avoids staggered abutment with the pump shaft 3, so as to hinder the upward movement of the impeller 2.
[0021] Further, the bottom of the supporting leg 17 is provided with a universal wheel 18, which facilitates the movement and adjustment of the position of the tool.
[0022] Further, one side of the frame 4 is symmetrically provided with a handrail 19, which facilitates the movement of the tool.
[0023] Further, when the handle 9 is in contact with one end of the through groove 7, the fixing rod 11 is located directly above the center hole, facilitating the quick movement of the fixing rod 11 to the position directly above the center hole.
[0024] The tool can conveniently and quickly take out the impeller 2 on the pump shaft 3, and when the impeller 2 is connected to the frame 4, the jack 10 is moved away to leave sufficient space for the operation of the staff, facilitate the adjustment of the position of the bolt 16, and fix the impeller 2 on the frame 4, and the movement and position adjustment of the tool are also more convenient through the setting of the universal wheel 18, and the use effect is good.
