Abstract
The invention discloses a safety hook ladder which comprises a cylindrical rod body, a plurality of supporting feet arranged on the peripheral wall of the rod body and a hook arranged at the upper end of the rod body.The hook comprises an upper hook body and a lower hook body.The upper hook body is fixed to the end of the rod body, the lower hook body is located below the upper hook body, the lower hook body is fixedly connected to a connecting rod inside the rod body, and the connecting rod can move in the extending direction inside the rod body.The safety hook ladder has the advantages that the upper hook body and the lower hook body in the hook can be separated and combined; when the upper hook body and the lower hook body are separated, an inlet is formed for enabling a cable to enter the upper hook body; after the upper hook body and the lower hook body are combined, the cable will not be disengaged from the hook, and safety is ensured.
Description
Technical field
The present invention relates to a kind of cat ladder, especially relate to a kind of safety ladder.
Background technology
At present, in power system, the hanging ladder for detecting cable is usually and includes the body of rod, hook, leg, during use, hang on cable, after body of rod lower end fixes, staff steps on support and swashes, but when staff climbs, it is easy to rock cable, probably occur that cable breaks off relations, at this moment, namely body of rod upper end does not support, and only lower end is fixed, the safety aligning the staff of climbing causes very big threat, it is easy to cause casualty accident.
Summary of the invention
It is an object of the invention to overcome the shortcoming and defect of above-mentioned prior art, it is provided that a kind of safety ladder, solve existing hanging ladder, in use, when rocking cable, it is easy to occur breaking off relations, it is possible to can cause casualties accident.
nullThe purpose of the present invention is achieved through the following technical solutions: a kind of safety ladder，Including a cylindrical body of rod，It is arranged on a plurality of leg on body of rod perisporium，It is arranged on the hook of body of rod upper end，Described leg is all perpendicular to the body of rod，Leg is divided into two rows，Orientation is all along the bearing of trend of the body of rod，Two row's leg opposing settings on the perisporium of the body of rod，And this two rows leg transpostion interval arrangement，Described leg is both provided with a link，Described hook includes rising to the bait and lower hook，Described rising to the bait is fixed on body of rod termination，Lower hook is positioned at lower section of rising to the bait，Lower hook is fixedly attached in the connecting rod being positioned at the body of rod，The body of rod is provided with the guide groove of bearing of trend at lower hook place，Connecting rod extends to the other end of the body of rod from one end of the body of rod，Connecting rod can be moved along bearing of trend in the body of rod，Thus promoting lower hook to move along guide groove，Lower hook is movable to laminating and rises to the bait，At this moment，Rise to the bait、Lower hook constitutes one and closes space，The lower end perisporium of the body of rod is provided with push rod，Push rod connects connecting rod，For promoting connecting rod.nullWhen this device uses，Staff pulls push rod，Connecting rod is moved down，So that lower hook separates with rising to the bait，Reveal import，Then import alignment cable，Cable is entered in hook，Staff promotes push rod again，Make connecting rod is moved，Promote and lower hook moves，Contact with rising to the bait，Complete to close space，Namely cable is positioned at closing space，At this moment，How cable rocks，All cannot disengage in hook，After body of rod lower end fixes，Staff is upwards climbed by leg，The setting of leg is that two rows are arranged dorsad，Namely it is parallel，When staff is positioned at before the body of rod，One row's leg is positioned at the left side，Another row's leg is positioned at the right，Two row's legs or transpostion interval arrangement，Namely first leg on the left side is as being positioned at body of rod bottom，First leg on the right is higher than first left leg，Second leg on the left side is higher than first leg in the right，Second right leg is again higher than second left leg，The like，And differ height should be consistent，And meet organization of human body，Staff is facilitated to climb，Staff is first leg that left foot first steps on the left side，Then right crus of diaphragm steps on first leg in the right，Then alternately climb，In climbing，Safety buckle is buckled on link，In the process constantly climbed，Constantly change link.
Further, the above-mentioned body of rod is provided with sliding tray at push rod place, push rod is perpendicular to the body of rod, and with connecting rod for being rotatably connected, sliding tray includes the major trough along body of rod bearing of trend, and two draw-in grooves laying respectively at major trough two ends, draw-in groove extends along body of rod circumferencial direction, and push rod moves in major trough, then promote connecting rod motion, when push rod is positioned at arbitrary draw-in groove, connecting rod then cannot move.Push rod promotes connecting rod to make lower hook and composition of rising to the bait closes space, and at this moment namely push rod arrives the draw-in groove place of upper end, and namely push rod enters this draw-in groove, consolidates connecting rod and lower hook, it is ensured that security performance.
The invention has the beneficial effects as follows: in hook rise to the bait and lower hook is separable and close, during separation, namely have an import, in rising to the bait for the entrance of cable, after closing, namely cable will not disengage in hook, it is ensured that safety.
