Abstract

An anti-drop insulating ladder head belongs to the technical field of design and manufacture of insulating ladder heads. The anti-drop insulating ladder head comprises an insulating ladder body and a suspension pulley. A movable shaft is provided with a locking piece. A spring is arranged between the locking piece and a pulley yoke. The end part of a transmission rod is provided with a single-piece shifting fork. The middle part of the transmission rod is provided with a double-piece shifting fork. The lower part of the insulating ladder body is provided with a rope ladder. An operator standing on the ground pulls a lifting rope, so that the transmission connecting rod drives the single-piece shifting fork to rotate downwards, and the single-piece shifting fork drives the locking piece on a pull rope and enables the head of the locking piece to erect upwards to form an opening with the pulley yoke, therefore, the suspension pulley can be lap-suspended on a ground lead very conveniently. After the lifting rope of the pulley is loosened, the locking piece returns to the original position under the action of the spring, thus closing the opening between the locking piece and the pulley yoke, therefore, the ladder can be safely suspended on the ground lead, and through the rope ladder, the operator can go to high position to work; and as the opening between the locking piece and the pulley yoke is closed, the ladder can not drop from the ground lead even when the ground lead swings greatly, thus ensuring the personnel safety of builders.

Description

Slip-off preventing Insulation ladder head
Technical field
The utility model belongs to the design and the manufacturing technology field of Insulation ladder head.
Background technology
At present in the maintenance of high voltage circuit or installing, the staff carries out aerial work often, adopts ladder shaft tower or hang on the lead wire and earth wire with ladder up and down, and the staff stands on the ladder and works.The hook on used ladder top all is open, and operating personnel are shaft tower or stand in top-operation up and down.Sometimes because conductor galloping or other reasons cause hook to come off easily, bring hidden danger to safety in production.
Summary of the invention
At above-mentioned situation, the purpose of this utility model provides a kind of slip-off preventing Insulation ladder head, to solve the problem that existing product exists.
Structure of the present utility model is as shown in drawings: by the insulating ladder body with hang pulley and constitute.Have one to hang pulley yoke at the top of insulating ladder body.On pulley yoke, have one to hang pulley.In the bottom of pulley yoke one movable axis is arranged.One locking sheet is arranged on movable axis.One spring is arranged between locking sheet and pulley yoke.On the top of terraced body one drive link is arranged.Have the monolithic shift fork in the end of drive link.At the drive link pars intermedia one biplate shift fork is arranged.Between monolithic shift fork and locking sheet, a backguy is arranged.Between two sheets of biplate shift fork, a shift fork backguy is arranged.Use of the present utility model is peace one pulley on lead wire and earth wire, and the pulley lifting rope ties up in the shift fork backguy.Rope ladder is installed in the bottom of insulating ladder body.Operating personnel stand in ground pulling lifting rope, make kinematic link drive the monolithic shift fork and rotate, and the monolithic shift fork drives the locking sheet in the backguy, and locking sheet head is upwards erected.And form opening between the pulley yoke.Hang pulley just at an easy rate lodge on lead wire and earth wire.Unclamp the pulley lifting rope then, the locking sheet is return-to-home position under spring action, closes the opening between locking sheet and the pulley yoke.So promptly ladder can be suspended on the lead wire and earth wire safely.Operating personnel just can from the rope ladder to top work because the opening between locking sheet and the pulley yoke is closed, even waving significantly appears in lead, ladder can not come off from lead yet.Thereby guaranteed constructor's personal safety.The utility model is simple in structure, and is reasonable in design.It is a kind of desirable safe hanging ladder.
