[0024] When using, first the tool is handled to the position where magnetic suspension vacuum pump frequency converter electric cabinet is located, according to the approximate size of frequency converter, the distance between two guide rails 3 is preliminarily adjusted by first drive assembly 5, so that the spacing between guide rail 3 is slightly greater than the width of frequency converter, so that subsequent tool can be placed in the appropriate position of frequency converter smoothly.

[0025] Then, the connecting hole 2 on the crossbeam 1 is connected with the external fixed support structure (such as gantry or other stable frame) by bolt connector, to ensure that the crossbeam 1 is fixed firmly and horizontally placed, to provide stable basis for the whole dismounting operation, and one end of two guide rails 3 extends into the electric cabinet and is located above the frequency converter.

[0026] Then, first drive assembly 5 is started again, and the positions of two guide rails 3 are accurately adjusted, so that they can be aligned with the edges of the two sides of the frequency converter.

[0027] Subsequently, according to the shape structure of the frequency converter and the position to be fixed, the second driving assembly 7 is used to drive the rope winding assembly 6 to move along the length direction of the guide rail 3, so that the rope winding assembly 6 is moved to a suitable position above the frequency converter, the rope winding assembly 6 is operated to lower the rope, the rope is wound around a suitable part (such as a lifting lug or a structural reinforcement part on the shell) of the frequency converter, and then the rope is tightened, so that the frequency converter is firmly bound on the rope winding assembly 6, and the frequency converter is removed at this time.

[0028] Subsequently, the second driving assembly 7 is started, the second driving assembly 7 moves the frequency converter out of the electric cabinet through the rope winding assembly 6, and then the rope winding assembly 6 is started again, so that the frequency converter is lowered and placed on a designated device, thereby facilitating maintenance of the frequency converter.

[0029] In this way, firstly, the parallel and spaced apart cross beams 1 build a stable frame, can disperse and bear the weight, and guarantee the stability of use, and the connecting holes 2 at the two ends are convenient for being connected with external support structures, further strengthen the stability, and can adapt to different working environments and the weight of the frequency converter.

[0030] Secondly, the first driving assembly 5 in the mounting groove 4 of the cross beam 1 can adjust the spacing of the guide rails 3, so that the tool can adapt to various models and sizes of the magnetic suspension vacuum pump frequency converter, and the universality of the tool in the actual application scene and the adaptability to different products are enhanced, and special disassembly tools do not need to be prepared for each frequency converter, thereby saving the cost and resources.

[0031] Thirdly, the guide rails 3 are arranged perpendicularly to the cross beams 1, cooperate with the second driving assembly 7 to drive the rope winding assembly 6 to move, and the operator can accurately control the position of the rope winding assembly 6 according to the shape, gravity center and fixing point of the frequency converter, so that the rope is fixed, and the balance and stability of the frequency converter during disassembly are ensured.

[0032] Finally, the tool realizes automatic movement of the disassembled frequency converter, so that a single person can complete the disassembly and replacement of the frequency converter, thereby effectively reducing the labor cost and the cost of employing workers, greatly improving the disassembly speed of the frequency converter, and finally improving the efficiency of the magnetic suspension vacuum pump system after-sales maintenance.

[0033] The first driving assembly 5 comprises a first driving motor 51 fixedly installed on the inner wall of one side of the mounting groove 4, a double-headed threaded rod 52 fixedly connected to the power output end of the first driving motor 51, the other end of the double-headed threaded rod 52 rotatably connected to the inner wall of the other side of the mounting groove 4, and two first driving blocks 53 symmetrically screwed on the double-headed threaded rod 52.

[0034] The bottom of the mounting groove 4 is provided with a movable groove 54 along the length direction thereof, two sliding blocks 55 are symmetrically and slidably connected in the movable groove 54, the top of the sliding block 55 is fixedly connected with the corresponding first driving block 53, and the bottom of the sliding block 55 is fixedly connected with the corresponding guide rail 3.

[0035] When it is necessary to adapt to the width of the frequency converter, first start the first driving motor 51, the rotation of the first driving motor 51 drives the double-headed threaded rod 52 to rotate, since the double-headed threaded rod 52 is threadedly connected with the two first driving blocks 53, and the first driving blocks 53 are limited to move along the axial direction of the double-headed threaded rod 52 under the cooperation of the movable slot 54 and the sliding block 55, with the rotation of the double-headed threaded rod 52, the two first driving blocks 53 will move towards or away from each other on the double-headed threaded rod 52 (depending on the rotation direction of the double-headed threaded rod 52), and since the first driving block 53 is fixedly connected with the sliding block 55, and the sliding block 55 is fixedly connected with the guide rail 3, the movement of the first driving block 53 will drive the guide rail 3 to realize corresponding translational movement, and adapt to the width of the frequency converter.

[0036] In this way, first, the two first driving blocks 53 are synchronously moved relative to or towards each other through the double-headed threaded rod 52, which ensures balanced and symmetrical movement of the two guide rails 3, and is beneficial to stable support and positioning of the object.

[0037] Secondly, the driving assembly is arranged in the mounting slot 4, which is reasonable in layout, saves space compared with double-motor driving, and avoids the problems of synchronization coordination and complex control.

[0038] Thirdly, the movable slot 54 cooperates with the sliding block 55 to provide stable linear motion guidance for the guide rail 3, which can reduce movement error and improve precision.

[0039] Finally, it is easy to realize automatic control, and the rotation direction and number of turns of the control driving motor can conveniently control the movement of the guide rail 3, which is convenient for integration with the control system to realize automatic operation.

[0040] The second driving assembly 7 comprises a second driving motor 71 fixedly installed in the guide rail 3, and a one-way threaded rod 72 fixedly connected with the power output end of the second driving motor 71, the other end of the one-way threaded rod 72 being rotatably connected with the inner wall of the guide rail 3.

[0041] Two sliding grooves 73 are symmetrically formed on the inner walls of the guide rail 3 along the length direction thereof, and a second driving block 74 is threadedly connected with the one-way threaded rod 72.

[0042] The two ends of the second driving block 74 respectively slide through the corresponding sliding grooves 73 to extend to the outer side thereof and are fixedly connected with mounting plates 75, and the rope winding assembly 6 is arranged between the two mounting plates 75.

[0043] When it is necessary to adjust the position of the rope winding assembly 6, the second driving motor 71 is started, and the second driving motor 71 drives the unidirectional threaded rod 72 connected thereto to rotate. Since the unidirectional threaded rod 72 is in threaded connection with the second driving block 74, and the two ends of the second driving block 74 are limited to be able to only linearly slide in the sliding grooves 73 on the two sides of the guide rail 3, during the rotation of the unidirectional threaded rod 72, the second driving block 74 will linearly move along the axial direction of the unidirectional threaded rod 72, and the mounting plate 75 fixedly connected at the two ends of the second driving block 74 will also synchronously move, thereby driving the rope winding assembly 6 located between the two mounting plates 75 to move along the length direction of the guide rail 3 to the required position.

[0044] In this way, first, the second driving motor 71 drives the unidirectional threaded rod 72 to drive the second driving block 74 to linearly displace through threaded transmission. The accurate control of the rotation angle and the number of turns of the second driving motor 71 can accurately position the rope winding assembly 6, and is suitable for high-precision winding hoisting scenes.

[0045] Secondly, the sliding grooves 73 of the guide rail 3 limit the linear movement of the second driving block 74, so that the mounting plate 75 and the rope winding assembly 6 move stably, reduce the winding and collision problems, and are beneficial to dynamic accurate winding.

[0046] Thirdly, the threaded connection has large transmission force, and the symmetrical connection of the driving block and the rope winding assembly 6 allows the load to be uniformly distributed, enhances the stability and service life, and meets the heavy load demand.

[0047] Finally, it is easy to realize automatic control. The rotation direction and the number of turns of the second driving motor 71 can be conveniently controlled to control the movement of the rope winding assembly 6, and it is convenient to integrate with a control system to realize automatic operation.

[0048] The rope winding assembly 6 comprises an electric hoist 61 fixed between the two mounting plates 75, and a steel wire rope 62 is arranged on the electric hoist 61.

[0049] In use, the electric hoist 61 is controlled to lower the steel wire rope 62, and the steel wire rope 62 is manually wound around appropriate parts of the frequency converter, such as lifting ears or structure reinforcing parts on the shell, to ensure that the winding mode of the steel wire rope 62 on the frequency converter is correct and stable, and no sliding or other situations occur in subsequent operations. Then, the electric hoist 61 is controlled again to start the lifting function, and the steel wire rope 62 is gradually tightened, so that the frequency converter is firmly bound on the steel wire rope 62.

[0050] The electric hoist 61 is a prior art and can be obtained by purchase. The working principle and the installation mode thereof are known to those skilled in the art, and thus will not be described in detail in the embodiment.

[0051] For those skilled in the art, according to the teachings of the present application, without departing from the principles and spirit of the present application, the changes, modifications, replacements and variations of the embodiments still fall within the scope of the present application.
