Detailed Description
The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1-13, an embodiment of the present invention provides a large-scale frequency converter shifting device, which includes a lifting frame 3, a wheel support 5 and a wheel 7.
The front end of the jacking frame 3 is provided with two parallel jacking frame connecting plates 1, and the jacking frame connecting plates 1 are provided with first pin holes.
The upper surface of the rear end of the jacking frame 3 is provided with a threaded hole, the lower surface is provided with a round hole, a threaded hole mounting bolt 4 is arranged, the round hole is communicated with the threaded hole, the round hole is penetrated through the upper end of the wheel support 5, the upper surface of the wheel support is butted with the bolt 4, and the jacking frame 3 can freely move up and down on the wheel support 5.
The wheel carrier 5 is connected with a wheel 7.
In one example, the frequency converter connecting plate 10 is further included, a second pin hole corresponding to the first pin hole is also formed in the frequency converter connecting plate 10, the frequency converter connecting plate 10 is welded at the bottom of the frequency converter, and the pin hole in the jacking frame connecting plate 1 is connected with the frequency converter connecting plate on the frequency converter through the mandrel 2.
In a more specific example, the distance between the two jack connecting plates 1 is larger than the thickness of the frequency converter connecting plate, and the difference between the distance and the thickness is not less than 0.5 mm.
In one example, the wheel carrier 5 is integrally connected to the wheel 7 by a wheel axle 6.
In one example, the fit clearance between the jacking frame 3 and the wheel bracket 5 is in the range of 0.05-0.1 mm.
The embodiment of the utility model also provides a large-scale frequency converter shifting method, which is applied to the large-scale frequency converter shifting device and comprises the following steps;
and step S1, welding a plurality of frequency converter connecting plates at the bottom of the large frequency converter.
And step S2, each frequency converter connecting plate is clamped between the jacking frame connecting plates of one jacking frame, and the core shaft penetrates through the first pin hole and the second pin hole to achieve the effect of connecting the large frequency converter and the jacking frame.
And step S3, when the large-scale frequency converter needs to be moved, the bolt is screwed clockwise, the large-scale frequency converter is lifted, and the large-scale frequency converter is pushed to a specified position.
And step S4, screwing the bolt anticlockwise, driving the large frequency converter to move downwards by the jacking frame until the large frequency converter falls to the ground, and finishing the movement of the large frequency converter.
