Electric system Rapid Combination lifting device
Technical field
The present invention relates to a kind of electric system Rapid Combination lifting device.
Background technology
In the routine of electric system, often need to carry out energising experiment to various electrical equipment, instrument etc. or utilize power tool to keep in repair, now just need to use source of AC.The access approaches of source of AC mainly contains two kinds, and a kind of is power supply on on-the-spot power equipment supply, and the second is generator set.Owing to being all generally power-off operation during field condition maintenance activity, therefore need to lay very long cable, both inconvenience was also dangerous.Even if scene is hot line work once in a while, not only need during on-the-spot power taking to use climbing tool, such as ladder etc., and can have a negative impact to Electro-metering and Electrical Safety.Therefore, when scene utilizes source of AC to carry out operation, generally all need the middle-size and small-size equipment such as delivery generator set in the wild.
Because the middle-size and small-size equipment qualities such as generator set are heavier, a three-phase diesel-engine generator about one ton of weight, generally needs 5,6 people to lift, and therefore deposits at outdoor or storehouse, mobile, field condition is unloaded, carry, entrucking is all very inconvenient.Buy fork truck fund too large (about 100,000 yuan), rent crane cost too greatly, by artificial lift to move not possibility, and there are very large danger factor, easily cause the crowded wound of staff, weigh wounded, injure by a crashing object.At ordinary times during the middle-size and small-size equipment such as dislocation generation unit, there are three kinds of operating mode: one, rent crane and carry out entrucking, be finished when returning and unload with crane again, crane lifting approximately needs 40 minutes to one hour (containing dispatching buses and the time of advent), not only lost time but also cost of idleness, and need to preengage crane in advance, have a strong impact on job schedule.Two, buy fork truck, about 100,000 yuan of fork truck, costly, and fork truck can not be dragged to field work scene by maintenance car, can only arrange driver driving fork truck in addition, very uneconomical.Three, use manual trailer to shift, first electrical generator manual trailer be transported in overhaul shop and (plan his use because overhaul shop separately has, do not allow to deposit this kind equipment), then use the row sling cart in overhaul shop, row sling cart approximately needs 20 minutes.Because electrical generator storage place also has segment distance apart from overhaul shop, be finished rear same mode and unload, very loaded down with trivial details and trouble.This mode is only suitable for using in intra-company's transfer, is not suitable for operation in the wild and uses.
In addition, when current electric system is safeguarded in the wild, generally can only carry ladder for ascending a height, therefore ladder has become must configuring of electric power maintenance car.Ladder on current electric power maintenance car is common foldable structure, and except electric power is ascended a height, do not have other purposes, therefore function ratio is more single.
