Embodiment
Below with reference to accompanying drawing, the specific descriptions of the optional embodiment of the present invention are given.
As shown in figure 1, frequency converter 10 includes framework 100 and multiple power models 200, its middle frame 100 includes multiple horizontal strokes
Beam 110 and multiple columns 120, these crossbeams and column are staggered to form multiple intervals for being used to accommodate power model 200 so that work(
Rate module 200 can be inserted into multiple intervals in framework 100 along guide rail 150 such as drawer-like.Inserted in power model 200
It is fixed together into framework 100 and then by power model 200 and framework 100.Needing to change or repair power model
When 200, direction (direction of arrow i.e. shown in Fig. 1) from the dorsal part from frequency converter 100 to front side that can be along is by power model
200 pull out.
Fig. 2 shows to be illustrated according to the power model with fixed structure the latter half of one embodiment of the present invention
Figure.As shown in Fig. 2 the top of power model 200 is provided with first baffle 210, second baffle 220 and fixed dam 230, its
At least one of height of middle first baffle 210 and second baffle 220 is less than on fixed dam 230 along block length side
To the height of the corresponding part in (direction of arrow i.e. shown in frequency converter depth direction or Fig. 1).
Fig. 3 A and 3B are shown according to the framework 100 with fixed structure top half of one embodiment of the present invention
Partial schematic diagram.As illustrated, positioner fixed part 130 and fixed is provided with crossbeam 110 above power model 100
Position device slipper 140, wherein positioner slipper 140 can be relative to positioner fixed part 130 on stroke
Slided up and down between end and stroke lower end.Preferably, as illustrated, the lower end of positioner slipper 140 is towards frequency converter
Dorsal part (direction in Fig. 4 shown in arrow) bending, so as to power model 200 insert framework 100 interval in when, with work(
The insertion of rate module 200, positioner slipper 140 can be consolidated under the promotion of power model 200 relative to positioner
130 automatic upward sliding of part is determined, so as to allow power model 200 to insert.After the insertion of power model 200, positioner
Slipper 140 returns to home position by self gravitation, so as to prevent power model from outwards skidding off.Pulled out from framework 100
During power model 200, it is necessary to which the manual-up positioner slipper that lifts could pull out power model 200.
The positioner fixed part 130 that is shown in Fig. 3 A and 3B forms the structure of bending so that fixed part 130 it is upper
End and the upper end of slipper 140 are placed in the both sides of crossbeam 110, and between the bending part and crossbeam 110 of fixed part 130
(right side of Fig. 4 middle cross beams 110) forms the space for allowing slipper 140 to slide up and down, but the scope of the present invention is not limited to
This.For example, it is also possible to positioner fixed part 130 is not formed to the structure of bending, but directly at it between crossbeam 110
(left side or right side of Fig. 4 middle cross beams 110) forms certain interval so as to allow slipper 140 to slide up and down.
Furthermore, it is possible to bending structure or similar structure are formed in the upper end of slipper 140, to prevent sliding stop part
140 fall in the absence of external forces.Only as an example, scope of the present application is not limited to shown in Fig. 3 A, 3B and Fig. 4
This.
Figure 4 and 5 schematically show the position relationship schematic diagram between power model 200 and framework 100, and show power
The position relationship and matching relationship schematic diagram between the fixed structure on fixed structure and framework 100 in module 200.
As shown in Figures 4 and 5, during power model 200 is pushed into framework 100, slipper 140 is first with first
Baffle plate 210 bumps against, so as to upward sliding, it is allowed to which power model 200 further moves inward.Then, slipper 140 and second
Baffle plate (not shown) bumps against, so as to upward sliding, it is allowed to which power model 200 further moves inward.Finally, it is of a relatively high to consolidate
Determine baffle plate 230 to be fixed together via bolt and fixed structure top half.In figure by fixed part 130, slipper 140 with
And the three of fixed dam 230 on power model 200 is fixed together, but scope of the present application is not limited thereto.For example,
Only fixed part 130 and fixed dam 230 can be fixed together, without fixed slipper 140.
It should here be understood that when slipper 140 is in its stroke lower end, the height of the lower end of slipper 140 should
When the height less than first baffle 210 and the appropriate section of second baffle 220, as shown in the partial sectional view in Fig. 4, but
The maximum height of one baffle plate 210 and second baffle 220 allows power model 200 to be inserted into framework 100 again, i.e., at least
Less than the downside of crossbeam 110.Although showing that the lower end of positioner fixed part 130 is less than crossbeam 110 in Fig. 4, also may be used
Flushed with being set to.
Fig. 6 to Fig. 8 shows the process for pulling out power model 200 from framework 100.Preferably, it can coordinate and be placed in rack
Small crane 300 that is upper or being independently arranged pulls out power model 200.
As shown in fig. 6, turning on the bolt between fixed dam 230 and fixed structure top half first, lifting rope is passed through
Hole on fixed dam 230, and pull out power model 200.After a segment distance is pulled out, because fixed structure upper half
The lower end of slipper 140 on part is by conducting oneself with dignity less than the upper end of the appropriate section of second baffle 220, so power can be prevented
The imprudence of module 200 slides out.Treat just power model 200 can be entered into one by after the upward sliding of slipper 140 manually
Step pulls out.Now, then by lifting rope the hole on second baffle 220 is further passed through, as shown in Figure 7.Now, power model
200 are hung by the safety of crane 300, thus can further manual-up mobile slipper 140, by power model
200 are completely pulled out slinging.
By above-mentioned all or part of structure, can by it is a kind of very simply and easily in a manner of in installation and removal power mould
It is automatically prevented from power model during block to fall, so as on the one hand protect power model not broken, on the other hand protection is grasped
Make the safety of personnel, the cost without dramatically increasing frequency converter.
It will be appreciated that though including first baffle 210 and second baffle 220 in aforementioned structure, but can also only set
One of those, rather than both set., can also be in power mould in order to sling its safety when power model is pulled out
The position for hanging lifting rope is set in addition on block, and is not limited to baffle plate in itself.
Although the present invention has shown and described with reference to some preferred embodiments of the present invention, those skilled in the art should
, can be in form in the case of without departing substantially from the spirit and scope of the present invention as defined in appended claims when understanding
It is made a variety of changes in upper and details.
