Technical field

The utility model relates to a kind of equipotential live line work device, particularly a kind of insulating flexible ladder head with anti-skidding defencive function.

Background technology

In high voltage power transmisson system, often need to process the foreign matter of the defect of high voltage power transmission and transforming circuit or suspension, its processing method is normally suspended on transmission line of electricity by insulating flexible ladder head and is slided to pending position by No. 1 equipotential live line work personnel, then No. 2 equipotential live line work personnel climb to insulating flexible ladder head along the rope ladder of insulating flexible ladder head lower end connection, process accordingly.The pulley that existing insulating flexible ladder head is mainly installed by rope ladder head support body, rope ladder head support body top forms, pulley is pressed on transmission line of electricity, in order to prevent insulating flexible ladder head slippage in operation process, in hook outside, secure latch is installed, operating personnel pins secure latch climbing to time on insulating flexible ladder head, then implements corresponding operation.The problem that this insulating flexible ladder head exists is: due to operating personnel need to climb along rope ladder could be by secure latch locking on insulating flexible ladder head time, therefore, in climbing process, insulating flexible ladder head easily and transmission line of electricity generation slippage, there is the accidents such as human body fall, there is certain potential safety hazard in existing insulating flexible ladder head, and because every circuit has sag, rope ladder head always slides to the direction of sag, cannot safety, work fast, only have with safety belt and around several circles, block pulley on wire, it is not slided toward the direction of sag, but this method is dangerous, can cause safety belt to destroy, when work firmly, health likely can be encountered the terraced head unit of protection, it is opened, the pulley of rope ladder head also may lift, greatly reduce safety factor.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of insulating flexible ladder head with anti-skidding defencive function that can prevent that rope ladder head from dropping and sliding.

To achieve these goals, the technical solution of the utility model is as follows:

A kind of insulating flexible ladder head with anti-skidding defencive function, comprise rope ladder head support body, pulley and blocking device, two tops of described rope ladder head support body are respectively equipped with the connected left column in top and right column, described blocking device is arranged on the left column of described pulley below, on described right column, be provided with the magnet that can coordinate with described blocking device, described blocking device comprises mounting plate, two fastening bolts and a jackscrew, described mounting plate with can freely rotate in the horizontal direction and can in the vertical direction under mobile mode be arranged on the left column of described pulley below, a described fastening bolt and left column can secure fit, another fastening bolt and right column can secure fit, described two fastening bolts are arranged at respectively described mounting plate both sides, described jackscrew is arranged at described mounting plate middle part.

Described mounting plate and described right column cooperation place are formed with one for placing the groove of right column.

Described fastening bolt top arranges annulus handle.

Described mounting plate is respectively arranged with limited block up and down.

Distance between described limited block is 300mm

The advantage of the insulating flexible ladder head with anti-skidding defencive function that the utility model provides is:

1,, by fastening bolt is set, can carry out the spacing between adjustable pulley according to the cross section of wire.

2, by jackscrew is set, make not produce relative sliding between rope ladder head and wire, the work that operating personnel can be felt at ease, guarantees safety.
