[0031] In order to make the purpose, structure, characteristics and functions of the utility model have further understanding, detailed description is as follows with example.

[0032] As Figures 1-5 shown, according to the utility model embodiment provides a kind of device of disassembling water pump rotor assembly impeller, comprising:

[0033] First support piece 1000, second support piece 2000, fixed pressing plate 3000, placement platform 4000, jacking assembly 5000, push assembly 6000 and blocking member 7000;

[0034] First support piece 1000 and second support piece 2000 are symmetrically arranged, fixed pressing plate 3000 is arranged at the top of first support piece 1000 and second support piece 2000, and the side wall of first support piece 1000 and second support piece 2000 is all arranged sliding groove 2100, and a plurality of first limit holes 2110 are arranged on sliding groove 2100, while the both ends of placement platform 4000 are provided with sliding block 4100, and a plurality of second limit holes 4110 are arranged on sliding block 4100, and placement platform 4000 is slid in sliding groove 2100 on first support piece 1000 and second support piece 2000 by sliding block 4100, and jacking assembly 5000 is arranged at the bottom of first support piece 1000 and second support piece 2000, jacking assembly 5000 is used for lifting placement platform 4000 in cooperation with sliding block 4100 of placement platform 4000, while push assembly 6000 is arranged at the central position of placement platform 4000, and blocking member 7000 is inserted in first limit hole 2110 and second limit hole 4110;

[0035] When the user uses the device for disassembling the impeller of the water pump rotor assembly to disassemble the inner impeller of the disassembled rotor assembly, first, the jacking assembly 5000 is installed at the bottom of the first support 1000 and the second support 2000, and the sliding blocks 4100 at both ends of the placement platform 4000 are clamped into the sliding grooves 2100 in the side walls of the first support 1000 and the second support 2000, so that the bottom of the sliding block 4100 cooperates with the jacking assembly 5000, and then the pushing assembly 6000 is installed at the center of the placement platform 4000. In actual use, the user places the rotor assembly with the impeller to be disassembled at the center of the placement platform 4000 by using a travelling crane or a hoisting device, ensures that the output end of the pushing assembly 6000 cooperates with the pump shaft of the impeller, and then fixes the fixed pressing plate 3000 to the top of the first support 1000 and the second support 2000. At this time, the user starts the jacking assembly 5000 to lift the placement platform 4000, so that the rotor assembly rises upward with the placement platform 4000, until the end of the rotor assembly contacts the fixed pressing plate 3000, thereby compressing the rotor assembly. After compression, the user starts the pushing assembly 6000 to push the impeller in the rotor assembly upward, the pushing assembly 6000 applies a pushing force upward, and the fixed pressing plate 3000 fixedly fixes the rotor assembly to generate a corresponding reaction force, so that the output end of the pushing assembly 6000 directly acts on the impeller, until the impeller is separated from the inner wall of the rotor assembly. After the impeller is separated, the user first removes the fixed pressing plate 3000, so as to facilitate personnel to take out the disassembled impeller, and finally the rotor assembly on the placement platform 4000 is unloaded by using a hoisting device.

[0036] Further, as shown in Figure 1 , Figure 2 and Figure 3 , the jacking assembly 5000 is a jacking hydraulic cylinder, and the jacking hydraulic cylinder is arranged at the bottom of the first support 1000 and the second support 2000. The output end of the jacking hydraulic cylinder cooperates with the bottom of the sliding block 4100. The position of the placement platform 4000 is adjusted according to the height of the rotor assembly. After the fixed pressing plate 3000 is installed, the jacking hydraulic cylinder can be started, and the output end of the jacking hydraulic cylinder lifts the sliding block 4100 upward in the sliding groove 2100, thereby driving the placement platform 4000 to rise, until the end of the rotor assembly contacts the fixed pressing plate 3000, thereby longitudinally clamping the rotor assembly.

[0037] Further, as shown in Figure 1 and Figure 5As shown, the fixed pressing plate 3000 is provided with a plurality of hollow grooves 3100. After the longitudinal clamping of the rotor assembly is completed, the user starts the pushing assembly 6000 to push the impeller in the rotor assembly. When the output end of the pushing assembly 6000 pushes out the impeller, the output end of the pushing assembly 6000 is pushed out by the hollow grooves 3100 of the fixed pressing plate 3000, which facilitates the continuous upward pushing force on the impeller and accelerates the impeller to separate from the rotor assembly.

[0038] Further, as shown in Figure 1 and Figure 5 , each hollow groove 3100 is provided with a sliding rail 3200, and a plurality of first fixing holes 3210 are arranged on the sliding rail 3200.

[0039] Preferably, as shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the device for disassembling the impeller of the water pump rotor assembly further comprises a clamping assembly 8000, the clamping assembly 8000 comprises a first clamping part 8100, a second clamping part 8200 and a fixed pin shaft 8140, the first clamping part 8100 and the second clamping part 8200 are the same structure, the first clamping part 8100 comprises a sliding block 8110, a connecting rod 8120 and a clamping piece 8130, the sliding block 8110 is provided with a groove, one end of the sliding block 8110 is connected with the connecting rod 8120, the connecting rod 8120 is connected with the clamping piece 8130, the sliding block 8110 is provided with a second fixing hole 8111, the sliding block 8110 is matched with the sliding rail 3200 through the groove, and the clamping assembly 8000 is positioned by inserting the fixed pin shaft 8140 into the first fixing hole 3210 and the second fixing hole 8111. In the actual operation of the device for disassembling the impeller of the water pump rotor assembly, the rotor assembly needs to be placed at the center position of the placing platform 4000 by manual operation to ensure that the output end of the pushing assembly 6000 directly acts on the center of the impeller. However, manual adjustment is prone to error. If the rotor assembly is not placed at the center position, the impeller will be offset in the rotor assembly, which is not conducive to pushing out the impeller again. To solve the above problems and ensure the smooth disassembly of the impeller, the clamping assembly 8000 is arranged to assist in positioning the rotor assembly and further apply a transverse force to the rotor assembly, so that the rotor assembly remains stable when the pushing assembly 6000 lifts the impeller. At the same time, the clamping assembly 8000 can meet the needs of rotor assemblies of different diameters, realizing the disassembly of rotor assemblies of multiple models.

[0040] The first clamping part 8100 and the second clamping part 8200 are arranged on the same sliding rail 3200, so that the first clamping part 8100 and the second clamping part 8200 move on the same straight line, the clamping pieces 8130 of the first clamping part 8100 and the clamping pieces 8130 of the second clamping part 8200 can clamp the rotor assembly at the same time, after the first clamping part 8100 and the second clamping part 8200 complete clamping of the rotor assembly, the second fixing hole 8111 of the sliding block 4100 of the first clamping part 8100 corresponds to the first fixing hole 3210 of the sliding rail 3200, and the second fixing hole 8111 of the sliding block 4100 of the second clamping part 8200 corresponds to the first fixing hole 3210 of the sliding rail 3200, and at this time, the clamped rotor assembly is located at the center of the placing platform 4000, and then the fixed pin shaft 8140 is inserted into the second fixing hole 8111 of the first clamping part 8100 and the second clamping part 8200 and the first fixing hole 3210 of the sliding rail 3200, so as to fix the positions of the first clamping part 8100 and the second clamping part 8200 on the sliding rail 3200, realize transverse fixing of the rotor assembly, improve the stability of the rotor assembly during disassembly of the impeller, and ensure that the rotor assembly is located at the center of the placing platform 4000.
