Description

Portable multi-function insulation operation ladder

Technical field

The utility model belongs to electric power overhaul utensil technical field, relates in particular to a kind of portable multi-function insulation operation ladder.

Background technology

Install in the professional site operation operation at electric power, many times can use insulating ladder.As a whole before and after the current insulating ladder, exist very big inconvenience in transit, the safe distance enough with the charging equipment maintenance to be noted in the onsite moving process, otherwise security incident can be caused.And function singleness, can not use as other instruments.

The utility model content

The technical problems to be solved in the utility model just provides a kind of convenient transportation, and the operation ladder can insulate at the portable multi-function that many occasions are used.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise the terraced body that is made of cross bar and montant, described terraced body is provided with first joint lock, second joint lock, the 3rd joint lock.

Its additional technical feature is: described first joint lock, second joint lock, the 3rd joint lock are unidirectional lock; The formation splayed is outwards rolled at the both ends of described montant; The both ends of described montant are provided with Slippery proof foot pad.

The portable multi-function insulation operation ladder that the utility model provides, terraced body is provided with first joint lock, second joint lock, the 3rd joint lock, a long ladder is transform as the combination of the short ladder of four joints.In the use, lock when all pinning in first joint lock, second joint lock, the 3rd joint, and ladder is in full swing, and can be used as the work high above the ground ladder and use; When the second joint lock curves inwardly, when first joint lock, the lock pinning of the 3rd joint, can be used as the fork ladder and use; When first joint lock, the 3rd joint lock curve inwardly, when the second joint lock pins, can be used as job platform and use; Lock and all curve inwardly when first joint lock, second joint lock, the 3rd joint, whole ladder is folded, convenient transportation.First joint lock, second joint lock, the 3rd joint lock are for unidirectional lock, and be easy to use, need not fix in addition.The formation splayed is outwards rolled at the both ends of montant, and is more firm.The both ends of montant are provided with Slippery proof foot pad, improve anti-slide performance.In order to guarantee the good insulation properties of ladder, terraced body adopts fiberglass insulation to make.
