[0014] The specific implementation of the present utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1-4 As shown, the utility model H8800 crusher positive pressure fan impeller remover is characterized by comprising a card plate Ⅰ2 and a card plate Ⅱ3, two embedded grooves 5 are respectively arranged on the inner side of the card plate Ⅰ2 and the card plate Ⅱ3, a semi-threaded hole 6 is respectively arranged at the lower part of each embedded groove, a bolt 4 connecting the card plate Ⅰ2 and the card plate Ⅱ3, a top screw 1,
[0016] The clamping plate I2 and the clamping plate II3 are matched together and tightened by the bolt 4, the two embedded grooves 5 are matched to form a stepped circular groove, the two semi-threaded holes 6 are matched to form a threaded hole, and the top screw 1 is threadedly connected to the threaded hole.
[0017] The shape of the embedded groove 5 matches the disassembly groove on the upper part of the impeller.
[0018] The utility model of the H8800 crusher positive pressure fan impeller remover adopts C45E4 high-quality carbon structural steel as raw material; the processing route is: cutting → forging → milling machine processing → drilling → machining → heat treatment. The processing technology of each stage is described as follows: 1. Cutting the material with 40 thick high-quality carbon structural steel plate, gas cutting into a prototype; 2. Forging requires air hammer forging, and heat preservation treatment after forging; 3. Milling machine processes the center plane and shape structure of the card plate; 4. Drilling, closing, and tightening the card plate 2 and the card plate 3 with bolts 4;
[0019] The present invention will be further described below:
[0020] 1. This impeller remover adopts an open-close structure and is tightened with two bolts 4 when in use;
[0021] 2. The impeller remover has two pairs of built-in grooves, which are composed of stepped circular grooves and are used to be embedded in the removal groove on the upper part of the impeller;
[0022] 3. When disassembling the impeller, first use half of the two clamps, for example, use clamp Ⅰ2, align the embedded groove 5 with the disassembly groove of the impeller, and then use the same method to put clamp Ⅱ3 in place, put on the two bolts 4 and tighten them with a wrench.
[0023] 4. Put a steel ball into the position where the two half-threaded holes 6 in the center of the clamping plate are combined into one threaded hole to reduce the resistance of the top screw 1 when it is twisted, so as to ensure flexibility and effort when grabbing the impeller; rotate the top screw 1 until the impeller is removed.
[0024] The utility model H8800 crusher positive pressure fan impeller disassembler improves the disassembly efficiency, ensures the disassembly quality, does not damage the crusher positive pressure fan impeller original parts, provides practical and convenient special tools for maintenance workers, reduces the damage rate of the crusher positive pressure fan impeller original parts to zero, and reduces the maintenance cost by more than 30%.
