The U-shaped left probe plate 604 is fixedly connected to the upper portion of the support arm 603 of the left probe 601, the U-shaped right probe plate 605 is fixedly connected to the upper portion of the support arm 603 of the right probe 602, the length of the right probe plate 605 is larger than that of the left probe plate 604, a magnet 606 is installed at the position where the right probe plate 605 and the left probe plate 604 are spliced, four distance detection sensors 607 are distributed on the vertical wall side of the left probe plate 604 side by side, four distance detection sensors 607 are distributed on the vertical wall side of the right probe plate 605 side by side, and four distance detection sensors 607 are distributed on the upper and lower cross arm sides of the right probe plate 605 side by side. Thus, a total of 16 distance detection sensors 607, up, down, left, right, and the like, constitute a leveling detection net, wherein half of the distance detection sensors 607 detect the shaft extension end of the centrifugal motor 4; the other half of the distance detection sensor 607 detects the shaft extension end of the pump body 5.

The specific use of this example is as follows:

for the condition that damage needs to be maintained and replaced

No matter the centrifugal motor 4 or the pump body 5 is damaged, only the damaged part needs to be detached for independent maintenance, and the spare part is quickly installed on the whole machine, so that the chemical production cannot be influenced.

The following description will be made in detail, taking the centrifugal motor 4 damaged as an example, of the whole procedure of installing the standby centrifugal motor 4:

firstly, breaking off and placing a left detector and a right detector of a leveling detection mechanism 6 at two sides, and then detaching a damaged centrifugal motor 4;

then, fixing the motor base 401 of the standby centrifugal motor 4 at the center position of the fixture block 402, and then inserting and fixing the fixture block 402 into the matching fixture seat 3;

then, the left and right detectors of the leveling detection mechanism 6 are folded, the leveling step is performed, the 8 distance detection sensors 607 in the first half of the leveling detection mechanism 6 detect the horizontal degree of the shaft extension of the pump body 5, the 8 distance detection sensors 607 in the second half detect the horizontal degree of the shaft extension of the newly installed centrifugal motor 4, and when the shaft extension of the newly installed centrifugal motor 4 is detected to be higher or lower than the shaft extension of the pump body 5, the PLC controller controls the main lifting platform 102 at the bottom of the centrifugal motor 4 to lift to the nearest position, so that the two shaft extensions are aligned up and down;

similarly, the distance detection sensor 607 of the leveling detection mechanism 6 can also detect whether the shaft extension of the pump body 5 is level with the shaft extension of the centrifugal motor 4 from left to right, and when the shaft extension is not level from left to right, the PLC controller controls the linear module 204 to drive the left and right moving plates 205 to drive the centrifugal motor 4, so that the two shaft extensions are level from left to right;

if the pump body 5 and the back-up centrifugal motor 4 are not subject to other problems or if they are not seriously aged, then the leveling is substantially completed by the above steps, and the coupling can be installed, but if the pump body 5 or the back-up centrifugal motor 4 are aged or otherwise damaged, and the rotating shafts of the pump body and the back-up centrifugal motor have coaxiality deviation, then the inclined moving device and the plane rotating device in the fine adjustment mechanism 2 are required to intervene for further leveling;

for example, after leveling through the above steps, when the up-and-down 8 distance detection sensors 607 of the rear half part of the leveling detection mechanism 6 detect that the shaft extension of the newly installed centrifugal motor 4 has a condition that one end is tilted up and down, the one set of hydraulic telescopic rods 202 will extend and retract, and the shaft extension is made horizontal by tilting the machine body;

for another example, when the left and right 8 distance detection sensors 607 at the rear half of the leveling detection mechanism 6 detect that one end of the shaft extension of the newly installed centrifugal motor 4 is deviated left and right, the pivoting support driving motor 207 drives the motor to rotate in a plane through the pivoting support 206, so that the shaft extension is flush with the left and right sides.

Through the steps, the two shaft extensions can be leveled accurately, and the shaft coupling can be continuously used after being installed.

Secondly, for monitoring and maintaining in daily practical use

The coaxiality of the two shaft extensions can be continuously monitored by the leveling detection mechanism 6, when deviation occurs, an alarm can be given at once, or the angle position of the centrifugal motor 4 or the pump body 5 can be automatically adjusted through the PLC according to the principle, so that the coaxiality of the shaft extensions is consistent all the time.

In addition, in this embodiment, the PLC controller may be preset with an automatic adjustment algorithm, or may be manually adjusted by an external PC device.

Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent substitutions made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
