Abstract
For changing the hand truck of 500kV current transformer, include two matching used large transport trolleys (1) and handling operation car (2), large transport trolley and handling operation car are installed with large bearing support frame (3) and little bearing support frame (4) respectively; The top carrying surface of large bearing support frame and little bearing support frame is recessed circular arc carrying surface, is respectively used to the major part and the microcephaly that carry 500kV current transformer; All be provided with in the outside of large transport trolley and handling operation car and adjustablely turn to handle (5), cardan wheel (6) is all equipped with in the bottom of large transport trolley and handling operation car.Adopt the utility model to change 500kV current transformer, can not power cut construction, safe and reliable, save time, laborsaving, economize and drop into.
Description
Technical field
The utility model belongs to the electric power reconstruction and extension project constructing device technical field at scene, high voltage installation charging operation place.Be specially and in advance new 500kV current transformer transported to the other hand truck of 500kV current transformer to be replaced.
Background technology
500kV SF6 current transformer or oil-immersed current transformer bulky, length is 6.3 meters, weight can reach 2.5 tons, and it is top-heavy, in the electric power reconstruction and extension project camp site in high voltage installation charging operation place, when changing this kind of current transformer, the current transformer transport Intrusive way of current employing is power failure operation, namely after grid equipment has a power failure and handled work permit formality, with crane, the new 500kV current transformer being placed on spacious appointment harbor is winched on lorry together with transport fixed mount, lorry is slowly transported to by current transformer to be replaced, with crane, new 500kV current transformer is hung on ground again, the old current transformer changed is hung on the transport fixed mount on lorry.New 500kV current transformer is installed afterwards.After installation, the old current transformer changed slowly is transported to spacious appointment harbor by lorry again, to hang oneself lower old current transformer from lorry with crane.By that analogy.
Adopt said method, because lorry body is higher, in high voltage installation charging operation place, current transformer is placed on railway carriage and when lifting by crane, can cause the electrical safety of camp site distance not (namely crane and current transformer equidistant, the electrical safety distance of high-voltage charged body not), therefore after must having a power failure, the transport work in place carrying out new 500kV current transformer could be started, cause the operational use time short, inefficiency, and operational space is narrow, transfer and portage difficulty is large.Not only time-consuming, effort, cost have high input, and also there is larger potential safety hazard, careless slightly, just likely injure the equipment such as current transformer, even injure workmen.
Summary of the invention
The purpose of this utility model be solve the deficiencies in the prior art, provide a kind of can not power cut construction, safe and reliable and save time, laborsaving, economize drop into the hand truck for changing 500kV current transformer.
The purpose of this utility model is achieved through the following technical solutions.
For changing the hand truck of 500kV current transformer, include two matching used large transport trolleys and handling operation car, large transport trolley and handling operation car are installed with large bearing support frame and little bearing support frame respectively; The top carrying surface of large bearing support frame and little bearing support frame is recessed circular arc carrying surface, is respectively used to the major part and the microcephaly that carry 500kV current transformer; All be provided with in the outside of large transport trolley and handling operation car and adjustablely turn to handle, cardan wheel is all equipped with in the bottom of large transport trolley and handling operation car.
This hand truck is provided with flexible cushion material on the circular arc carrying surface of the large bearing support frame of large transport trolley and the little bearing support frame of handling operation car.
The utility model is owing to adopting the hand truck carrying 500kV current transformer being positioned at ground, make in camp site, high voltage installation charging operation place, the electrical safety distance of 500kV current transformer and high-voltage charged body is enough far away, thus can when not having a power failure, just adopt large transport trolley and handling operation car to be transported to by current transformer to be replaced in advance by new 500kV current transformer, then having a power failure more changes jobs.Can be energized after replacing completes at once, then with large transport trolley and handling operation car, the old current transformer changed be transported out of high voltage installation charging operation place.Adopt the utility model, adjusted by operation, in advance new current transformer is transported to position to be replaced, effectively reduce equipment power off time, improve work efficiency.And operational space is openr, transport carrying difficulty reduces greatly, and operational risk also significantly reduces, and improves working security.The utility model structure is simple, easy to use, drops into little.Transport trolley adopts large and small two transport trolleys to support the use, and the large and small bearing support frame of difference mounting strap circular arc bearing surface on large and small two transport trolleys, for major part and the microcephaly of difference loaded current transformer, solve the carrying risk easily brought because current transformer is top-heavy in transportation.Promote large and small transport trolley by manpower during carrying simultaneously, save time, laborsaving, safe and reliable, in advance new current transformer can be pushed into and change immediately below place, be convenient to more change jobs.

Fig. 1 is front view of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the left view of Fig. 1.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model includes two matching used large transport trolleys 1 and handling operation car 2, large transport trolley 1 and handling operation car 2 are installed with large bearing support frame 3 and little bearing support frame 4 respectively, the top carrying surface of large bearing support frame 3 and little bearing support frame 4 is recessed circular arc carrying surface, is respectively used to the major part and the microcephaly that carry 500kV current transformer.The circular arc carrying surface of large bearing support frame 3 and little bearing support frame 4 is provided with flexible cushion material.All be provided with in the outside of large transport trolley 1 and handling operation car 2 and adjustablely turn to handle 5, cardan wheel 6 is all equipped with in the bottom of large transport trolley 1 and handling operation car 2.
Adopt the method for the utility model replacing 500kV current transformer as follows:
A. large transport trolley 1 and handling operation car 2 are pushed into be placed on specify harbor new 500kV current transformer by, be placed on large transport trolley 1 and handling operation car 2 after new 500kV current transformer being sling with crane; The major part of current transformer and microcephaly are placed on the large bearing support frame 3 of large transport trolley and the little bearing support frame 4 of handling operation car respectively;
B. promote large transport trolley 1 with manpower and handling operation car 2 moves simultaneously, new 500kV current transformer is transported to the position of current transformer to be replaced; Turn to handle 5 to adjust its respective cardan wheel 6 by large transport trolley 1 and respective adjustable of handling operation car 2, thus control the moving direction of large transport trolley 1 and handling operation car 2;
C. the old current transformer two ends changed from high voltage installation charging operation place are placed on respectively on the large bearing support frame 3 of large transport trolley and the little bearing support frame 4 of handling operation car, promote large transport trolley 1 with manpower and handling operation car 2 moves simultaneously, old current transformer is transported to appointment stowed location.
