[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] See also Figures 1 to 3 Now, a slurry pump impeller lifting tool provided by the utility model is described. A slurry pump impeller lifting tool comprises a longitudinally arranged main beam 1, a lifting plate 2 is horizontally arranged at the upper end of the main beam 1, a fixing sleeve 3 is arranged on the outer side of the lower part of the main beam 1, an adjusting screw 4 is longitudinally penetrated in the fixing sleeve 3, the upper and lower ends of the adjusting screw 4 are respectively provided with threaded sections with opposite rotation directions, a first clamping claw 5 is horizontally arranged above the fixing sleeve 3, and a second clamping claw 6 is horizontally arranged below the fixing sleeve 3, the first clamping claw 5 and the second clamping claw 6 are both slidably arranged along the length direction of the main beam 1, the first clamping claw 5 and the second clamping claw 6 are respectively connected with two threaded sections in a one-to-one correspondence, and positioning notches 7 are provided on the opposite sides of the inner sides of the first clamping claw 5 and the second clamping claw 6.

[0021] The utility model provides a slurry pump impeller lifting tool. Compared with the prior art, the top of the main beam 1 is provided with a lifting plate 2, the lower outer side is provided with a fixing sleeve 3, the fixing sleeve 3 is penetrated with an adjusting screw 4, the upper and lower parts of the fixing sleeve 3 are respectively provided with a first claw 5 and a second claw 6, the two claws are slidably arranged along the main beam 1, the outer sides of the first claw 5 and the second claw 6 are respectively threadedly connected with the adjusting screw 4, and the opposite sides of the inner sides of the first claw 5 and the second claw 6 are respectively provided with positioning notches 7. When the slurry pump impeller lifting tool provided by the utility model is used to lift the impeller, the lifting plate 2 is connected to the lifting device, the adjusting screw 4 is first rotated, and the two claws are close to each other and inserted into the impeller water inlet. The adjusting screw 4 is rotated in the opposite direction again, the two claws are separated from each other, and the two positioning notches 7 are respectively clamped on the inner edge of the impeller water inlet. The lifting device lifts the lifting plate to lift the impeller as a whole, replacing the way of lifting the impeller by an iron chain or a lifting belt, which is easy to operate and will not cause damage to the impeller.

[0022] Among them, the distance between the opposite sides of the first claw 5 and the second claw 6 is adjustable, the maximum gap can reach 800mm, and the minimum spacing is 270mm. It can adapt to the water inlet size of most slurry pump impellers and is suitable for lifting most slurry pump impellers.

[0023] The main beam 1 includes two angle steel plates 15, which are symmetrically spaced and form a connection gap between them. The lifting plate 2 is fixed to the upper end of the connection gap, the lower end of the connection gap is fixed with a support plate 8, the lower part of the connection gap is fixed with a fixing plate 9, and the fixing sleeve 3 is fixed to the outer side of the fixing plate 9. The lifting plate 2, the support plate 8 and the fixing plate 9 are respectively welded and fixed in the connection gap formed by the two angle steel plates 15, so that the overall main beam 1 remains stable.

[0024] Specifically, one end of the lifting plate 2 is fixed in the connecting gap, and the other end of the lifting plate 2 extends inward and is provided with a lifting hole 10. The lifting hole 10 is used to connect the rope or hook of the lifting equipment, so that the center of gravity of the tooling can be moved toward the impeller side as a whole in the lifting state to ensure the stability of the impeller in the lifting state.

[0025] Specifically, the height of the lifting plate 2 gradually increases from the inside to the outside, which can reduce the material consumption and reduce the weight of the entire tooling.

[0026] In addition, a balancing block 11 is horizontally fixed in the middle and upper part of the connecting gap. The balancing block 11 extends to the outside of the two angle steel plates 15 and is provided with a balancing hole 12. The balancing block 11 extends to the outside of the two angle steel plates 15, which can ensure the balance of the overall tooling during lifting. If the dead weight of the lifted impeller is large, the corresponding counterweight block can also be hung using the balancing hole 12 to prevent the impeller from tilting significantly during the lifting state.

[0027] See also Figure 1 and Figure 2 , both sides of the first claw 5 and the second claw 6 are provided with limit blocks 13, and the limit blocks 13 are located on the inner sides of the two angle steel plates 15. The limit blocks 13 can prevent the two claws from moving outward, and restrict them from lateral separation from the connection gap, and can only slide in the connection gap along the length direction of the main beam 1.

[0028] In addition, the middle of the adjusting screw 4 is provided with a polished rod section, which penetrates the fixing sleeve 3 and rotates along the axial direction of the fixing sleeve 3, and the two sides of the polished rod section are respectively provided with positioning nuts 14. There is a gap between the outer peripheral wall of the polished rod section and the central hole of the fixing sleeve 3 to ensure that the adjusting screw 4 can rotate freely in the fixing sleeve 3, and the positioning nut 14 can prevent the adjusting screw 4 from moving along the axial direction to prevent it from escaping from the fixing sleeve 3.

[0029] Preferably, the positioning notch 7 is a triangular notch, which is adapted to the shape of the inner edge of the impeller water inlet. The triangular notch can perfectly fit the inner edge of the impeller water inlet. When lifting the impeller, the triangular notch fits tightly with the inner edge of the impeller water inlet and will not cause any bumps to the inner edge of the impeller water inlet.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
