Description
Technical field
It the utility model is related to overhaul of line breaker field, more particularly to disposed withdrawn type vacuum circuit breaker inspection platform.
Background technology
Since more than ten years, vacuum circuit breaker has obtained vigorous growth, especially 10kV withdraw-types vacuum circuit breaker in China
Device, because its replacing is convenient, suitable for frequent operation, arc-chutes do not have to maintenance the advantages that, in electricity substation and switching station
To being widely applied.Handcart is the important component in 10kV withdraw-type breakers, positioned at breaker bottom.In breaker disjunction
In the case of, spread after guide rail and can be extracted out of switch cubicle it out with hand, to be overhauled or to be changed.Because that can pull out by hand,
And shape is similar to trolley, so being called handcart.
When the overhaul of 10kV disposed withdrawn type vacuum circuit breakers or handcart are broken down, it is necessary to dismount handcart, and manpower mode
During maintenance, due to 10kV breaker small volumes, weight weight, and it can not collide so that this, which works, has the person easily injury, equipment
It is easily damaged, the problems such as working strength is big, efficiency is low.Therefore, how to simplify 10kV withdraw-type breakers overhaul operation, improve maintenance
Quality, reduce the problem of maintenance risk becomes a worth thinking.
In the prior art, the transfer car(buggy) of breaker all only has this function of breaker transfer, if will be to circuit breaker internal
And breaker bottom handcart repaired if just must have hanging device or manpower lifts breaker, spend substantial amounts of
Artificial and transhipment time, and hanging device can also be limited to by switchgear house space.
Authorization Notice No. is that CN206099126U Chinese patent literature discloses " a kind of vacuum circuit breaker overhaul scaffold ", is wrapped
Jacking system, pallet and suspension hook are included, in use, handcart and breaker are positioned on pallet, pallet rises to jacking system
At suspension hook, by the disassembling bolts between handcart and breaker, breaker is hooked by suspension hook, then adjusting jacking system makes pallet
Downwards, so as to breaker it is hanging, now handcart still on pallet, can rival car overhauled.
This prior art floor space is small, is easy to deposit, and can not only be used for breaker transfer trolley, and and can realizes circuit breaker cart
Maintenance, but there is also following defect：1st, there is no handcart fixing device on the pallet of the overhaul of line breaker frame, breaker is rising
Or easily it is subjected to displacement during declining.And there is no handcart slide rail adjustment hole, narrow application range in the pallet, it is impossible to meet all
The use demand of the breaker of model.2nd, the overhaul of line breaker frame hangs breaker by suspension hook, and suspension hook slidable connection is in horizontal stroke
Liang Shang, under this hang, breaker easily shakes.3rd, the up-down mode of the overhaul of line breaker frame is to twist height manually to adjust
Knob is saved, automaticity is low, waste of manpower, and the mode of manual adjustment has the problem of lifting speed is irregular, can also make
Rock or even collide into breaker.4th, the overhaul of line breaker frame does not have brake system, whole during rising on-board the circuit breaker
Repairing frame easily slides.
