Compared with the prior art, the novel effect of this realization is as follows:
this travelling crane dolly design is exquisite, and occupation space is little, overhauls the handling switch at the electric substation in the pit and has fine practicality. The movable crane trolley is used in the maintenance of the underground high-voltage explosion-proof switch, so that the safety risk of the original manual lifting switch body is eliminated, and the labor intensity of maintenance personnel is greatly reduced. Especially, the transformer substation is unattended, the number of maintainers and inspection personnel is correspondingly reduced, particularly in the middle and night shifts, once the high-explosion body has problems and needs to be moved, people need to be dispatched from a new city to go into a well in the past, and the delay time is long. At present, only one person is needed to operate the simple crane, so that the maintenance time is saved, and the influence on production is reduced.
The input-output ratio is as follows: the total investment cost for developing the mobile lifting trolley is about 1200 yuan, and about 46 workers can be saved every year according to the number of the underground explosion-proof high-voltage switches which are currently maintained by a locomotive team. The labor cost saved by the maintainers is about =46 × 200=9200 (yuan) per year, and the input-output ratio is 1200:9600= 1: 8. If the trolley is put into use, the labor intensity of workers is reduced, the switch moving safety is improved, and maintenance events are saved, so that the trolley has greater value significance.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
