Embodiment
Below with reference to accompanying drawing, give the specific descriptions of Alternate embodiments of the present invention.
As shown in Figure 1, frequency converter 10 comprises framework 100 and multiple power model 200, its middle frame 100 comprises multiple crossbeam 110 and multiple column 120, these crossbeams and column are staggered to form multiple interval for holding power model 200, in multiple intervals that power model 200 can be inserted into along guide rail 150 as drawer-like in framework 100.After power model 200 is inserted in framework 100, then power model 200 and framework 100 are fixed together.Needs change or maintenance power model 200 time, along from the dorsal part of frequency converter 100 to the direction (direction of arrow namely shown in Fig. 1) of front side, power model 200 can be pulled out.
Fig. 2 illustrates the power model schematic diagram with fixed structure the latter half according to one embodiment of the present invention.As shown in Figure 2, the top of power model 200 is provided with the first baffle plate 210, second baffle 220 and fixed dam 230, and wherein the height at least partially of the first baffle plate 210 and second baffle 220 is less than the height along the corresponding part in block length direction (i.e. the direction of arrow shown in frequency converter depth direction or Fig. 1) on fixed dam 230.
Fig. 3 A and 3B illustrates the partial schematic diagram of the framework 100 with fixed structure the first half according to one embodiment of the present invention.As shown in the figure, crossbeam 110 above power model 100 is provided with positioner standing part 130 and positioner slipper 140, wherein positioner slipper 140 can slide up and down between stroke upper end and stroke lower end relative to positioner standing part 130.Preferably, as shown in the figure, the lower end of positioner slipper 140 is bending towards the dorsal part (direction in Fig. 4 shown in arrow) of frequency converter, so that when power model 200 inserts in the interval of framework 100, along with the insertion of power model 200, positioner slipper 140 can relative to positioner standing part 130 upward sliding automatically under the promotion of power model 200, thus allow power model 200 to insert.After power model 200 inserts, positioner slipper 140 relies on self gravitation to get back to home position, thus prevents power model from outwards skidding off.When pulling out power model 200 from framework 100, manually must upwards mention positioner slipper could pull out power model 200.
Positioner standing part 130 shown in Fig. 3 A and 3B forms the structure of bending, the upper end of the upper end of standing part 130 and slipper 140 is made to be placed in the both sides of crossbeam 110, and (right side of Fig. 4 middle cross beam 110) forms the space allowing slipper 140 to slide up and down between the bending part and crossbeam 110 of standing part 130, but scope of the present invention is not limited thereto.Such as, positioner standing part 130 can not formed the structure of bending yet, but directly between itself and crossbeam 110 (left side of Fig. 4 middle cross beam 110 or right side) form certain interval thus allow slipper 140 to slide up and down.
In addition, bending structure or similar structure can be formed in the upper end of slipper 140, in case sliding stop part 140 is fallen in the absence of external forces.Shown in Fig. 3 A, 3B and Fig. 4 only exemplarily, the scope of the application is not limited thereto.
Figure 4 and 5 schematically show the position relationship schematic diagram between power model 200 and framework 100, and the position relationship between the fixed structure on power model 200 and the fixed structure on framework 100 and matching relationship schematic diagram are shown.
As shown in Figures 4 and 5, pushed by power model 200 in the process of framework 100, first slipper 140 bumps against with the first baffle plate 210, thus upward sliding, allow power model 200 to move inward further.Then, slipper 140 and second baffle (not shown) bump against, thus upward sliding, allow power model 200 to move inward further.Finally, relatively high fixed dam 230 is fixed together via bolt and fixed structure the first half.In figure, fixed dam 230 three on standing part 130, slipper 140 and power model 200 is fixed together, but the scope of the application is not limited thereto.Such as, only standing part 130 and fixed dam 230 can be fixed together, and not fix slipper 140.
Here be to be understood that, when slipper 140 is in its stroke lower end, the height of the lower end of slipper 140 should lower than the height of the appropriate section of the first baffle plate 210 and second baffle 220, as shown in the partial sectional view in Fig. 4, but the maximum height of the first baffle plate 210 and second baffle 220 allows power model 200 can be inserted in framework 100 again, namely at least lower than the downside of crossbeam 110.Although the lower end of the standing part of positioner shown in Fig. 4 130 is lower than crossbeam 110, also can be set to and flushes.
Fig. 6 to Fig. 8 illustrates the process pulled out from framework 100 by power model 200.Preferably, the small crane 300 be placed on rack or independently arrange can be coordinated to be pulled out by power model 200.
As shown in Figure 6, first turn on the bolt between fixed dam 230 and fixed structure the first half, by lifting rope through the hole on fixed dam 230, and pull out power model 200.After pulling out a segment distance, because the lower end of the slipper 140 in fixed structure the first half is by the upper end of deadweight lower than the appropriate section of second baffle 220, so can prevent power model 200 from sliding out because of carelessness.Treat, manually by after slipper 140 upward sliding, just power model 200 to be pulled out further.Now, then lifting rope is further passed through the hole on second baffle 220, as shown in Figure 7.Now, power model 200 is hung safely by crane 300, and therefore can manually move up slipper 140 further, slings to be pulled out completely by power model 200.
By above-mentioned all or part of structure; in the process of installation and removal power model, automatically can prevent power model from falling in a kind of mode very simply and easily; thus protection power model is not broken on the one hand; the safety of protection operating personnel on the other hand, and significantly do not increase the cost of frequency converter.
Although should be appreciated that in aforementioned structure and comprise the first baffle plate 210 and second baffle 220, also only one of them can be set, instead of both arrange.In order to it being sling safely when power model is pulled out, the position hanging lifting rope can also be set in addition on power model, and be not limited to baffle plate itself.
Although illustrate and describe the present invention with reference to some preferred embodiment of the present invention, but it will be appreciated by those skilled in the art that, when not deviating from the spirit and scope of the present invention as defined in appended claims, can make a variety of changes it in the form and details.
