The impeller installation by using the ventilator impeller assembling device comprises three steps of operations, namely:

the piston rod 322 of the expansion part 32 of the first-step expansion mechanism 3 is inserted into the impeller shaft hole 83: as shown in fig. 7 and 8, firstly, the ventilator impeller assembling device is moved to the impeller 8 through the wheel mechanism 5, the lifting hook 41 of the hoisting mechanism 4 is hooked with the impeller inlet 82 of the impeller 8 to be installed (the shaft hole key slot 831 of the impeller 8 is ensured to be upward before hoisting), an operator controls the lifting hook 41 of the hoisting mechanism 4 to vertically move upward, after the impeller 8 leaves the ground, the slide connecting part 31 of the telescopic mechanism 3 is controlled to vertically move downward, and at the moment, the slide connecting part 31 of the telescopic mechanism 3 and the lifting hook 41 of the hoisting mechanism 4 move in opposite directions, so that the time is saved, and the installation efficiency is improved. After the operation is carried out for a period of time, the piston rod 322 of the telescopic mechanism 3 and the impeller shaft hole 83 are at the same horizontal height, the operation of the hoisting mechanism 4 is suspended, the position of the key groove 323 of the telescopic part on the piston rod 322 is aligned with the key groove 831 of the shaft hole, then the piston rod 322 is controlled to move towards the direction of the impeller shaft hole 83, the flat key is clamped into the key groove 831 of the shaft hole at the moment, the impeller 8 is fixed and does not rotate any more, as shown in fig. 8, the lifting hook 41 can be removed at the moment, and therefore the operation of inserting the piston rod 322 of the telescopic part 32 of the telescopic mechanism 3 into the impeller shaft hole 83 is completed.

The second step moves the ventilator wheel assembly with the impeller 8 to a position close to the housing to be installed and positioned horizontally: the casing weight is usually hundreds of kilograms, and weight is heavier, drives wheel mechanism 5 through power unit 6 and moves to the position that is close to the casing, and the casing includes the main shaft, and the main shaft is the part that links to each other with impeller shaft hole 83 after the installation, in order to realize the main shaft and impeller shaft hole 83 are coaxial, need to guarantee that piston rod 322 is coaxial with the main shaft. The horizontal direction positioning is completed by adjusting the vehicle body mechanism 1.

Thirdly, positioning in the vertical direction and pushing the impeller 8 to the main shaft: the slide coupling portion 31 of the telescopic mechanism 3 is controlled to move vertically up and down in the slide rail 21, and the positioning in the vertical direction is performed, and the movement is stopped when the piston rod 322 of the telescopic mechanism 3 moves to be flush with the main shaft. At this time, the piston rod 322 of the telescopic mechanism 3 is moved towards the inside of the housing until it abuts against the spindle, and the flat key on the telescopic mechanism 3 is aligned with the flat key on the spindle. At this time, the installer pushes the impeller 8 up to the main shaft in the axial direction of the main shaft, and the installation is completed.

When impeller 8 was dismantled from the casing to ventilation blower impeller assembly quality, stretched into the casing with telescopic machanism 3's piston rod 322 earlier, the parallel key on the telescopic machanism 3 aligns with the epaxial parallel key of main, and the installer moves out of casing with telescopic machanism 3's piston rod 322 slowly with the cooperation of the parallel key of impeller 8 and telescopic machanism 3. At this time, the lifting hook 41 of the hoisting mechanism 4 is put down to hook the impeller 8, then the piston rod 322 of the telescopic mechanism 3 is withdrawn, the impeller 8 is slowly put down by the hoisting mechanism 4, and the impeller 8 is completely disassembled at this time.

In the step of inserting the first telescopic mechanism 3 into the impeller shaft hole 83, after the piston rod 322 of the telescopic mechanism 3 is inserted into the impeller shaft hole 83, the hoisting mechanism 4 is started to vertically move downwards for a period of time, then the telescopic part 32 retracts along the length direction of the telescopic part, and finally the lifting hook 41 of the hoisting mechanism 4 is started again to vertically move upwards, so that the step of separating the lifting hook 41 of the hoisting mechanism 4 from the impeller 8 is realized.

Example 2

The difference between this example and example 1 is: hoisting machine constructs 4 and includes electro-magnet portion, and electro-magnet portion is located hoisting machine and constructs 4 bottoms, and when the assembly, electro-magnet portion and 8 magnetism of impeller are connected.

Example 3

The difference between this example and example 1 is: the ventilator impeller assembling device further comprises a vehicle body lengthening mechanism detachably connected with the rear end of the vehicle body.

Generally, the impeller weight is about 100 kilograms, the weight is heavier, the specifications of the impellers 8 are different, the weight difference of the impellers 8 is larger, therefore, when the impellers 8 with larger specifications and heavier weights are conveyed, the stacking heights of a plurality of balancing weights 7 are higher simply by increasing the number of the balancing weights 7, the gravity center is higher, certain potential safety hazards exist, the whole length of the vehicle body mechanism 1 is increased by increasing the vehicle body lengthening mechanism, the area for placing the balancing weights 7 is further increased, the rollover when the heavier impellers 8 are conveyed is avoided, the conveying range of the fan impeller assembling device is enlarged, and the safety is improved.

Example 4

The difference between this example and example 1 is: in this embodiment, the telescoping mechanism 3 does not include a driving device, and a through hole is formed on the slide rail 21 of the support mechanism 2; an internal threaded hole is formed in the side, away from the telescopic part 32, of the slide block of the slide way connecting part 31; when the slide block of the slide way connecting part 31 needs to be fixed, the bolt penetrates through the through hole of the bracket mechanism 2 to be matched with the internal thread hole of the slide block of the slide way connecting part 31.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes to be applied in other fields, but all the technical matters of the present invention are not departed from the technical contents of the present invention, and any simple modification and equivalent changes made to the above embodiments according to the technical matters of the present invention still belong to the protection scope of the technical solution of the present invention.
