A slurry pump casing 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 slideway is arranged downwardly inclined from the outside to the inside at the upper part of the main beam 1, a first clamping claw 3 is arranged in the slideway, a first driving member is arranged at the outer end of the first clamping claw 3, and the first driving member is used to drive the first clamping claw 3 to slide along the slideway, a second clamping claw 4 is transversely arranged at the lower part of the main beam 1, the second clamping claw 4 is slidably arranged along the length direction of the main beam 1, a slide groove 6 is provided in the second clamping claw 4 along the length direction, a second driving member is provided at the outer end of the second clamping claw 4, and the second driving member is used to drive the second clamping claw 4 to slide along the slide groove 6, and the first clamping claw 3 and the second clamping claw 4 are provided with positioning notches 8 on the opposite sides of the inner sides.

[0023] The utility model provides a slurry pump jacket lifting tool. Compared with the prior art, the top of the main beam 1 is provided with a lifting plate 2, the upper part of the main beam 1 is provided with a slideway, the slideway is provided with a first claw 3, and the first driving member drives the first claw 3 to slide along the slideway. The lower part of the main beam 1 is provided with a second claw 4 for sliding, the second claw 4 is provided with a slideway 6 along the length direction, the second driving member drives the second claw 4 to slide along the slideway 6, and the first claw 3 and the second claw 4 are provided with positioning notches 8 on the opposite sides of the inner sides. When using the slurry pump jacket lifting tool provided by the utility model, the lifting plate 2 is connected to the lifting device, the second claw 4 is first slid upward, the first claw 3 and the second claw 4 are inserted into the jacket water inlet, the first claw 3 slides along the slideway toward the inner side of the jacket water inlet, and the second claw 4 slides along the slideway 6 toward the inner side of the jacket water inlet. The second claw 4 is gradually slid downward until the lower end surface of the second claw 4 fits the lower edge of the water inlet of the sheath, and the first claw 3 and the second claw 4 are slid outward until the positioning notches 8 of the two are respectively clamped on the inner edge of the water inlet of the sheath. The lifting equipment lifts the lifting plate 2 to lift the sheath as a whole, replacing the method of lifting the sheath with an iron chain or a lifting belt, which is easy to operate and will not cause damage to the sheath.

[0024] Among them, the distance between the opposite sides of the first claw 3 and the second claw 4 is adjustable, the maximum gap can reach 500mm, and the minimum spacing is 150mm. It can adapt to the water inlet size of most slurry pump jackets and is suitable for lifting most slurry pump jackets.

[0025] 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, a fixing block is fixed to the lower end of the connection gap, a slide is provided at the upper part of the connection gap, and the second clamping claw 4 is slidably provided at the lower part of the connection gap. The lifting plate 2 and the fixing plate are welded in the connection gap formed by the two angle steel plates 15, so that the overall main beam 1 remains stable.

[0026] Specifically, one end of the lifting plate 2 is fixed in the connection gap, and the other end of the lifting plate 2 extends inward and is provided with a lifting hole 9. The lifting hole 9 is used to connect the rope or hook of the lifting equipment, so that the center of gravity of the tooling can be moved to one side of the sheath as a whole in the lifting state to ensure the stability of the sheath in the lifting state.

[0027] 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.

[0028] In addition, a balancing block 10 is fixedly arranged horizontally in the middle of the connection gap, and the balancing block 10 extends to the outside of the two angle steel plates 15 and is provided with a balancing hole 11. The balancing block 10 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 lifting sleeve is large, the corresponding counterweight block can be hung using the balancing hole 11 to prevent the sleeve from tilting significantly during lifting.

[0029] See also Figure 1 Two guide slide blocks 12 are provided at the upper part of the connecting gap. The opposite sides of the two guide slide blocks 12 are provided with guide slide surfaces parallel to each other. The guide slide surfaces are planes inclined downward from the outside to the inside. A slideway is formed between the two guide slide surfaces. The width between the two guide slide surfaces is adapted to the width of the first claw 3, ensuring that the first claw 3 can slide along the two guide slide surfaces.

[0030] Specifically, the outer side of the first clamping claw 3 is provided with a first bent portion bent upward, and the first driving member is a first bolt 13. The first bolt 13 is transversely threaded and passes through the first bent portion, and one inner end of the first bolt 13 abuts against the outer side of the guide slider 12. By rotating the first bolt 13, the first clamping claw 3 can slide along the slideway, so that the positioning notch 8 on the inner side of the first clamping claw 3 is completely fitted on the upper edge of the water inlet of the sheath.

[0031] See also Figure 1 The lower parts of the two angle steel plates 15 are provided with strip grooves 5 along their length direction, and positioning bolts 7 are provided in the two strip grooves 5, and the positioning bolts 7 penetrate the slide groove 6. Two strip grooves 5 are provided on each angle steel plate 15, and each positioning bolt 7 penetrates the strip groove 5 and the slide groove 6 horizontally to achieve the horizontal and vertical adjustment of the second clamping claw 4. When the second clamping claw 4 is adjusted into place, it is locked by a nut to keep the second clamping claw 4 stable.

[0032] Specifically, the outer side of the second clamping claw 4 is provided with a second bent portion bent upward, and the second driving member is a second bolt 14, the second bolt 14 is transversely threaded and penetrates the second bent portion, and one inner end of the second bolt 14 abuts against the outer side of the angle steel plate 15. By rotating the second bolt 14, the second clamping claw 4 can slide along the slide groove 6, so that the positioning notch 8 on the inner side of the second clamping claw 4 is completely fitted on the lower edge of the water inlet of the sheath.

[0033] Preferably, the positioning notch 8 is a triangular notch, which is adapted to the shape of the inner edge of the sheath water inlet. The triangular notch can perfectly fit the inner edge of the sheath water inlet, and when the sheath is lifted, the triangular notch fits tightly with the inner edge of the sheath water inlet without causing bumps to the inner edge of the sheath water inlet.

[0034] 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.
