Description

Technical Field

[0001] The utility model relates to an impeller flipping, hoisting and fastening tooling, belonging to the technical field of ore car impeller assembly. Background Technique

[0002] The existing process of flipping and hoisting the blower impeller is as follows: during the operation, the operator directly binds the lifting rope to the impeller and directly performs the flipping, hoisting, installation and fastening operations.

[0003] During the flipping and hoisting process, it is easy to interfere with the blower when hoisting the impeller. The lifting rope gets in the way, the installation steps are too complex and it is difficult to hoist it in. The position of the hoisting and installation hole cannot be controlled, the hoisting is prone to loosening and the efficiency is low. Moreover, when fastening the impeller, it is easy to drive the engine crankshaft to rotate, which cannot meet the production efficiency and work safety.

[0004] The main reasons for the above are that there is no special hoisting and installation equipment, and the clearance between the ore car impeller and the blower is small. It is easy to loosen when using a lifting rope to bind, it is not easy to position the flat key, and the engine crankshaft is in a non-fixed state, making the installation process difficult.

When assembling the impeller, the connection through hole can cooperate with a crowbar to fasten the impeller; the bottom of the connection component II is inserted into the connection through hole, and the connection component I can rotate on the connection component II, thereby driving the connection disk 7 and the impeller to rotate together, so as to adjust the hoisting center of gravity of the entire tooling; the locking component acts on the connection between the connection component I and the connection component II to fix the two together; the hoisting component is installed at the top of the connection component II and can flip and lift the impeller by 90 degrees after cooperating with a lifting tool.

[0039] The following further describes the above-mentioned connection disk.

[0040] As Figure 1 、 Figure 2 、 Figure 3 shown, the axial side surface of the connection disk 7 is provided with a circumferential through hole, which corresponds to the circumferential threaded hole on the impeller one by one; the fasteners are a plurality of bolts 6, and the bolts are installed from the connection disk 7 to the impeller circumference to fixedly connect the two.

[0041] In a further solution, the inner hole diameter dimension of the connection disk 7 is not less than the center hole diameter dimension of the impeller, so as to avoid interference between the connection disk 7 and the motor shaft inserted into the center hole of the impeller.

[0042] In a further solution, after the connecting component I rotates on the connecting component II to form a Z-shaped structure, the lifting component and the lifting tool cooperate to flip the impeller by 90 degrees; after the connecting component I rotates on the connecting component II to form a C-shaped structure, the lifting point of the lifting component and the center of gravity of the impeller are on the same straight line, and the lifting component and the lifting tool cooperate to lift the impeller.

[0043] The following further explains the above-mentioned connecting component I.

[0044] As Figure 1 、 Figure 2 、 Figure 4 shown, the connecting component I includes a connecting plate 8 and a bushing 4; the inner end face of the connecting plate 8 is a flat structure, and it is fixed to the connecting disk 7 perpendicular to it; the outer end face of the connecting plate 8 is a concave arc surface structure, and it is fixed together after being fitted with the radial outer peripheral surface of the bushing 4, and the inner hole of the bushing 4 is used as a connecting through hole.

[0045] In a further solution, continuing to refer to Figure 4 shown, the connecting component I further includes at least one rib plate 3, which is fixed at the connection between the connecting plate 8 and the bushing 4.

[0048] In a further solution, continuing to refer to Figure 4 、 Figure 5 shown, the locking component is at least one nut 5, and at least one nut 5 is screwed onto the rod part of the bolt 6. After continuous screwing in, the bushing 4 is pressed against the head of the bolt 6, and then the bushing 4 is clamped between the nut 5 and the head of the bolt 6.

[0049] In a further solution, continuing to refer to Figure 1 、 Figure 2 shown, the lifting component is a lifting plate 1 with at least one lifting hole.

[0050] The following gives the working process of the above-mentioned impeller flipping, lifting and fastening tooling in combination with the attached Figure 6 drawing.

[0051] As shown in Figure 6a, first, adjust the elbow pipe 2 and the connecting plate 8 by loosening the nut 5 so that the elbow pipe 2 and the connecting plate 8 form a Z-shaped structure. Then, the connecting disk 7 is fastened to the impeller through the circumferential bolts. The lifting rope passes through the lifting plate 1 to turn over the impeller.

After adjusting the elbow pipe 2 and the connecting plate 8 to a C-shaped structure, make the lifting point of the lifting plate 1 and the center of gravity of the impeller on the same straight line. Then, fasten the nut 5 again. As Figure 6 shown in Figure 6c, hoist the impeller into the blower. Pass the center hole of the impeller through the generator shaft. Then, remove the nut 5 and remove the elbow pipe 2, the lifting plate 1, and the bolt 6 as a whole. Insert a crowbar into the shaft sleeve 4 to fix the engine crankshaft and assist in torque setting of the impeller closing nut. As Figure 6 shown in Figure 6d.

[0052] In summary, the utility model adopts a detachable design. By rotating the tooling components, it is convenient to adjust the tooling and the center of gravity of the impeller to be on the same straight line, realizing the synchronous completion of the impeller turning-over and hoisting actions, and the hoisting effect is safer. By using the tooling, the lifting point is separated from the workpiece to avoid interference when the impeller is installed inside the blower. After the elbow pipe, the lifting plate, and the bolt are removed as a whole, they can be used as the impeller installation tooling. Insert a crowbar against the shaft sleeve to fasten the impeller. The overall structure is simple, the turning-over and hoisting process is easy to operate, the hoisting efficiency is higher, and the labor intensity is greatly reduced. The structure is designed with lightweight, reducing the self-weight while ensuring the strength. The rib plate is welded on the connecting plate to increase the strength of the structural member. There is sufficient space margin during the turning-over and hoisting process to avoid bumping and scratching during the process. The overall structure is simple and the operation is convenient and fast.
