Description
Technical field
The utility model is related to a kind of tool, specifically a kind of easy single rack ladder device for substation equipment maintenance and repair work.
Background technology
In existing substation equipment maintenance and repair work, since power transformation primary equipment framework is higher or equipment is higher, upkeep operation process
In need using insulating ladder carry out upkeep operation work.General 6 meters of glass fibre reinforced plastic insulating stepladder total amounts are 75kg, ordinary circumstance descending stair
Son needs 3 to 4 people resultant force to set up, and is easy to cause band electrical distance insufficient with neighbouring charging operation equipment in erection process
Electric shock injures and deaths are caused to operating personnel；Operating personnel in erection process due to the effect of weight is easy to damage, sprain, weigh wounded,
Cause personal injury.
Utility model content
The technical issues of the utility model is solved be provided for on-site personnel it is a kind of safe, simple, light, efficient
Simple rack ladder device, can effectively reduce the risk that electric shock injures and deaths and personal injury occur during ladder for staff, carry
The operating efficiency of high operating personnel mitigates the labor intensity of operating personnel.
The utility model solves above-mentioned technical problem with following technical solution：
The utility model Simple rack ladder device, it includes carrying wheel and ladder holder, and ladder branch is placed on carrying wheel top
Just it moves, roller is installed at the top of ladder holder, the top of ladder holder is equipped with double-hook wire grip, the lower part of ladder holder
Live roller is installed, the bracing wire of double-hook wire grip connect around after live roller with one of insulating ladder, insulating ladder it is another
Head is placed in above roller.
The fixation suspension hook of the double-hook wire grip is fixedly connected with ladder holder, the guy hook and insulating ladder of double-hook wire grip
Connection.
The middle part of ladder holder described in the utility model has been connected with the support leg for reinforcing supporting role by articulated manner.
The utility model Simple rack ladder device has the following advantages that：
1, ladder is set up using the utility model Simple rack ladder device, can effectively reduces touching in operating personnel's operation process
Risk and personal injury risk, substantially reduce the labor intensity of on-site personnel, during setting up ladder and carrying ladder
Heavier glass fibre reinforced plastic insulating stepladder is manually carried, staff can be reduced to completion with 2 people from 3 to 4 original people and (set up ladder
In the process also can 1 people's complete independently, people's whole process monitoring).
2, the risk that staff damages, sprains, weighing wounded is greatly reduced, personal injury risk is effectively controlled and subtracts
Low operating risk；
3, carry wheel due to being provided with, can alleviator personnel in the handling process labor intensity, also using simple
Ladder device carries ladder.
4, the utility model is simple in structure, easy to operate, can easily found the glass fibre reinforced plastic insulating ladder stay for the 75kg that weighs
With put down；
5, the utility model can easily erect ladder in the 35kV outdoor electricity distributions battery limits that both sides interval is charged and fall
Ladder can reduce about 60% due to carrying out erection and work of falling merely with the space above device during erecting and falling
Erection and be put into the space of ladder, avoid that personal electric shock casualty accident occurs during setting up or being put into ladder.

Specific implementation mode
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model Simple rack ladder device includes carrying wheel 1 and ladder holder 2, ladder branch
Frame 2 is placed on carrying wheel 1 and can be moved easily, and the top of ladder holder 2 is equipped with roller 2-1 by bearing, ladder holder 2 it is upper
Portion is equipped with double-hook wire grip 2-2, and the lower part of ladder holder 2 is equipped with live roller 2-4, the bracing wire 2-5 of double-hook wire grip 2-2
It is connect with one of insulating ladder 3 around after live roller 2-4, the other end of insulating ladder 3 is placed on roller 2-1.
The fixation suspension hook (not shown) of the double-hook wire grip 2-2 forms a fixed connection with ladder holder 2, and double hook is tight
The guy hook (not shown) of line device 2-2 is formed with insulating ladder 3 and is connected.
In order to reinforce supporting, support leg 2-3 is symmetrically connected by articulated manner in the on both sides of the middle of ladder holder 2.
The ladder holder 2 can be welded by angle steel or aluminium alloy light framework is bolted, and angle steel is 4 × 4cm
It makes.
Triangle wheel can be used in the carrying wheel 1, to be conveniently steered and move.
The double-hook wire grip 2-2 is universal hook cord holder comprising two hooks, one is fixed suspension hook, separately
One is the guy hook being connect with bracing wire external part.
In use, ladder holder 2 is transported in field process by toolhouse as shown in Figure 1, insulating ladder 3 is hung over ladder
On holder 2, staff lifts the front end of insulating ladder 3 by hand, using carry wheel 1 carry insulating ladder 3, staff just as with
Carrier carries ladder.
After insulating ladder 3 is transported to working site, insulating ladder 3 is placed into ground by staff, and ladder holder 2 is fixed
It is good, a lift of insulating ladder 3 is placed on the roller 2-1 of ladder holder 2, as shown in Figure 2.Then again by double-hook wire grip 2-
2 guy hook is connect with the other end of insulating ladder 3, is started the tightening action of double-hook wire grip 2-2, is driven by bracing wire 2-5 exhausted
The lower end of edge ladder 3 moves horizontally, the upper end of insulating ladder 3 slowly uplink under the action of roller 2-1 and live roller 2-4, until
Until ladder upper end rides on equipment frame.
When ladder needs to fall, insulating ladder 3 being placed on the roller of ladder holder 2, a people stands on carrying wheel, and one
People drags ladder lower end, ladder slowly downlink under the action of its own gravity and roller.
