Abstract
The utility model discloses a kind of travelling car for the dismounting of large volume frequency converter, it is characterized in that: described travelling car is that base plate is provided with two tracks, and mobile flat board is established by wheel and arranged in orbit, and mobile flat board is held the bottom of frequency converter.Owing to adopting above-mentioned structure, the utility model is used easy to operate, and manufacturing cost is cheap, can effectively improve dismounting and frequency converter efficiency is installed, and by removing and installing a frequency converter, needs to use till now for 7～10 hours 1～2 hour of this dolly.Greatly shorten the repair time, guaranteed the normal production of coke oven, reduced the stove rate of losing, directly or indirectly improved the productivity effect of coke oven.
Description
Technical field
The utility model relates to electrical overhaul field, particularly a kind of travelling car for the dismounting of large volume frequency converter.
Background technology
Existing coking coke oven coke quenching car has all adopted advanced variable-frequency control technique, in order to meet its high-speed cruising condition, the engineering frequency converter that crawler body is equipped with, because its volume is large, weight is heavier, and be arranged in narrow and small regulator cubicle, to plant maintenance, bring great inconvenience.
Because affected by electric elements layout in cabinet, in the process that large volume frequency converter is overhauled, dismounting and mounting single-conversion device need be with 7～10 hour, have a strong impact on normally the carrying out of production of coke oven, in addition because of the fluctuating of motorcycle track, locomotive, in operational process, vibrates greatlyr, and the backboard bolt of rear end plate that causes fixing frequency converter damages and buries the unsafe hidden danger of locomotive operation.
For the problems referred to above, a kind of novel travelling car is provided, realizing and dismantling at short notice and install large volume frequency converter is the problem that prior art need to solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of travelling car for the dismounting of large volume frequency converter, to reach the object of dismantling at short notice and installing large volume frequency converter.
For achieving the above object, the technical solution of the utility model is that a kind of travelling car for the dismounting of large volume frequency converter, is characterized in that: described travelling car is that base plate is provided with two tracks, mobile flat board is established by wheel and is arranged in orbit, and mobile flat board is held the bottom of frequency converter.
Described base plate bottom is provided with lower margin.
The height of described lower margin is that bolt connects, and conveniently it is highly regulated.
The dull and stereotyped size of described movement is identical with the bottom size of frequency converter.
A kind of travelling car for the dismounting of large volume frequency converter, owing to adopting above-mentioned structure, the utility model is used easy to operate, manufacturing cost is cheap, can effectively improve dismounting and frequency converter efficiency is installed, by removing and installing a frequency converter, need to use till now for 7～10 hours 1～2 hour of this dolly.Greatly shorten the repair time, guaranteed the normal production of coke oven, reduced the stove rate of losing, directly or indirectly improved the productivity effect of coke oven.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is a kind of travelling car structural representation for the dismounting of large volume frequency converter of the utility model;
Fig. 2 is a kind of travelling car construction profile schematic diagram for the dismounting of large volume frequency converter of the utility model;
Fig. 3 is a kind of travelling car principle of work schematic diagram for the dismounting of large volume frequency converter of the utility model;
In Fig. 1,1, base plate; 2, track; 3, mobile dull and stereotyped; 4, lower margin; 5, frequency converter.
The specific embodiment
Large volume frequency converter can be dismantled and install to the utility model at short notice.In the situation that reducing service personnel labour intensity, resume production fast, thereby can reduce to greatest extent the off-time of causing because of frequency converter failure.
Concrete the utility model is that base plate 1 is provided with two tracks 2 as Figure 1-3, and mobile flat board 3 is established by wheel and is arranged on track 2, mobile dull and stereotyped 3 bottoms of holding frequency converter 5.Base plate 1 bottom is provided with lower margin 4.The height of lower margin 4 is that bolt connects, and conveniently it is highly regulated.Mobile dull and stereotyped 3 size is identical with the bottom size of frequency converter 5.
During dismounting, the wiring of frequency converter 5 bottoms is removed, frequency converter 5 bottoms, as the electric elementss such as reactor shift out outside cabinet, are pushed to frequency converter bottom by dolly, regulate the bolt of lower margin 4, make mobile dull and stereotyped 3 bottoms of being close to frequency converter 5, dolly rear side is carried out counterweight, in case frequency converter 5 is while departing from fixed base plate, there is " nose " phenomenon in dolly, after frequency converter 5 drops on dolly completely reposefully, dolly can be pulled out outside cabinet, dismounting finishes.
During installation, new frequency converter 5 is put on mobile dull and stereotyped 3 and slowly pushes in cabinet and (carry out equally counterweight), slowly regulate the bolt of lower margin 4, make the fixed orifice of frequency converter 5 and the fixed orifice contraposition on cabinet base plate, with bolt of rear end plate, frequency converter is fixed on cabinet tank top plate.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted technical solutions of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
