Due to the design limitations of the slurry pump, the gap between the volute and the impeller is less than 10mm. When installing the volute, the fingers of maintenance personnel are easily squeezed by the volute and the impeller, which is prone to safety accidents; 2) The labor intensity is high. The weight of the volute is about 50kg. Three people are required to lift and install it at the same time during installation, and multiple adjustments are required, which consumes labor costs and has low work efficiency.

The terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0017] like Figures 1 to 3 As shown, the slurry pump volute installation tool involved in the present application includes a first installation handle 1 and a second installation handle 2, and the first installation handle 1 and the second installation handle 2 have the same structure and both include a horizontal portion 12, a first inclined portion 13 and a second inclined portion 14, wherein a lifting ring is provided on the upper surface of the left end of the horizontal portion 12, the right end of the horizontal portion 12 is connected to the upper end of the first inclined portion 13, the first inclined portion 13 is inclined toward the lower right direction, the angle between the horizontal portion 12 and the first inclined portion 13 is an obtuse angle, the lower end of the first inclined portion 13 is connected to the upper end of the second inclined portion 14, the second inclined portion 14 is inclined toward the lower left direction, the angle between the first inclined portion 13 and the second inclined portion 14 is an acute angle or a right angle, and a claw is provided at the lower end of the second inclined portion 14, and the claw is located below the horizontal portion 12. In this embodiment, the horizontal portion 12, the first inclined portion 13 and the second inclined portion 14 are integrally formed, the lifting ring on the first mounting handle 1 is recorded as the first lifting ring 10, the claw on the first mounting handle 1 is recorded as the first claw 8, the lifting ring on the second mounting handle 2 is recorded as the second lifting ring 11, and the claw on the second mounting handle 2 is recorded as the second claw 9.

[0018] The second mounting handle 2 is horizontally flipped relative to the first mounting handle 1 so that the two can be used together. A pin mounting hole is provided on the first mounting handle 1, and a pin mounting hole is also provided at a corresponding position of the second mounting handle 2. The first mounting handle 1 and the second mounting handle 2 are hinged together through the cooperation of the pin 3 and the pin mounting hole. The two claws can extend into the volute 7 and can clamp the volute 7.

[0019] In this embodiment, the first mounting handle 1 and the second mounting handle 2 are made of 30*50mm galvanized square tubes to increase the strength of the structure. The clamping claws are made of 50mm angle steel, and their mounting strength is greater than 100kg. The distance between the two clamping claws matches the inner diameter of the volute 7.

[0020] In order to adapt to slurry pump volutes 7 of various specifications, the hinge positions of the first mounting handle 1 and the second mounting handle 2 are adjustable to adjust the distance between the two claws when the horizontal parts 12 of the first mounting handle 1 and the second mounting handle 2 are in a horizontal state. Specifically, a first group of pin shaft mounting holes 4 are provided on the second inclined part 14 of the first mounting handle 1, and a second group of pin shaft mounting holes 5 are provided on the second inclined part 14 of the second mounting handle 2. Each pin shaft mounting hole in the first group of pin shaft mounting holes 4 corresponds to each pin shaft mounting hole in the second group of pin shaft mounting holes 5. When it is necessary to adapt to slurry pump volutes 7 of different specifications, the corresponding pin shaft mounting holes are selected so that the distance between the two claws matches the inner diameter size of the volute 7, and the first mounting handle 1 and the second mounting handle 2 are hinged together through the cooperation of the pin shaft 3 and the pin shaft mounting holes.

[0021] In this embodiment, a support spring 6 is provided between the first inclined portion 13 of the first mounting handle 1 and the first inclined portion 13 of the second mounting handle 2. When the horizontal portion 12 of the first mounting handle 1 and the horizontal portion 12 of the second mounting handle 2 move, the support spring 6 applies a force to restore the two to a horizontal state.

[0022] In the specific use process, firstly, according to the inner diameter of the volute 7, two corresponding pin shaft mounting holes in the first group of pin shaft mounting holes 4 and the second group of pin shaft mounting holes 5 are selected, and the first mounting handle 1 and the second mounting handle 2 are hinged together through the cooperation of the pin shaft 3 and the pin shaft mounting holes, so that when the horizontal parts 12 of the first mounting handle 1 and the second mounting handle 2 are in a horizontal state, the distance between the two claws matches the inner diameter of the volute 7. Then, the first mounting handle 1 and the second mounting handle 2 are manipulated to reduce the distance between the two claws, and the two claws are placed inside the volute 7, and the two ends of the lifting belt are respectively placed in the two lifting rings, and the crane is operated to move upward, and the distance between the two claws automatically increases to match the inner diameter of the volute 7 until it is tightened, and the lifting operation is completed.

[0023] The slurry pump volute installation tool involved in the present application only needs one person to operate when using a crane for lifting operations, and two people are required to operate when using manual installation. The lifting process is fast, safe and reliable. According to the weight of the volute 7 and the working site environment, two operation methods can be selected: manual lifting and lifting operations.

[0024] The slurry pump volute installation tool involved in the present application has the advantages of simple structure, simple manufacturing process, easy operation, high installation safety factor and low cost. By adjusting the distance between the two claws, it can be used in the installation site of slurry pump volutes of various specifications, and can meet the requirements of fast, tight and installation. If it is promoted and used in the same industry, it will have great safety and social benefits.

[0025] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
