Abstract
The invention discloses a hook ladder for cable repairing.The hook ladder for cable repairing comprises a cylindrical rod body, multiple supporting feet arranged on the peripheral wall of the rod body, a hook arranged at the upper end of the rod body and a fixator arranged at the lower end of the rod body, wherein the supporting feet are in threaded connection with the rod body through threaded ends, a circumferential groove is formed in each supporting foot, and a matched rubber sleeve is arranged in the circumferential groove.The hook ladder has the advantages that one rubber sleeve is arranged on each supporting foot in the hook ladder, convex strips are further arranged on each rubber sleeve to increase a friction force between shoe soles and the supporting feet, and a slip phenomenon rarely occurs during climbing, the supporting feet are in threaded connection with the rod body, and the ladder can be used again by mounting one new supporting foot after one supporting foot is damaged, so that repair is very convenient.
Description
Technical field
The present invention relates to a kind of cat ladder, especially relate to a kind of cable and repair hanging ladder.
Background technology
nullAt present，In power system，Hanging ladder for detecting cable is usually and includes the body of rod、Hook、Leg，During use，Hang on cable，Staff steps on support and swashes，When but staff climbs，But existing leg is typically all a circular bar，When staff climbs，It is very easy to skid，Although having security protection rope to hang on hanging ladder，Will not be in peril of one's life，But staff still can be bumped to leg，Thus it is injured，The strength that also membership dues are very big returns on hanging ladder，Very big inconvenience is brought to staff，And the leg of existing hanging ladder is all welded on the body of rod，Need when climbing to support very big power，Often occur damaging，Ladder need to be taken repair shop during repairing，Then a new leg is welded again，The trouble very but this seems in carrying，During repairing, ladder can't use，Have influence on job schedule.
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 cable repairs hanging ladder, solves 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 cable repairs hanging 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，If son is at the holder of body of rod lower end，Described holder includes fixing bar and rotary joint，Rotary joint is a cylinder，The upper end of its one end and fixing bar is rotatably connected，The other end is threadedly coupled on body of rod lower end，Can turn mutually in a circumferential direction between rotary joint and fixing bar，But it is non-movable in the axial direction，The lower end of fixing bar is tip，On its perisporium, helical ring is wound with stop leaf，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 passes through the threaded body of rod of the end of thread，And the end of thread runs through the body of rod，Its termination is exposed from opposite side，The termination of the end of thread is connected to a nut，Leg arranges a circumferential groove，The bottom land of circumferential groove is provided with the tooth of circumferential arrangement，The rubber case of coupling it is provided with in circumferential groove，The periphery wall of rubber case is provided with axial raised line，Wherein in row's leg，Suspension ring it are both provided with between two adjacent legs.When this device uses, it is hooked on cable, holder according to circumstances screws in ground, it is usually the inclination body of rod, body of rod lower end ground clearance is coordinated with holder length, select place that holder turn enters ground, rotary joint bassets, rotary joint is connected with the body of rod, at this moment namely body of rod lower end is fixed, and upper end be hook with cable be tensioned state, namely making body of rod upper and lower side is all fixing shape, it is difficult to be shaken, even if hook breaks off relations, because lower end is fixing, the body of rod is without falling down, ensure that the safety of staff, and the fixed form of holder is to squeeze in ground by fixing bar, fixing bar arranges spiral helicine stop leaf, it is not too difficult for screwing in ground, but want directly to extract, because stopping the stop of leaf, extremely difficult, only rotate and extract, this ensure that the lower end of the body of rod is fixed.When staff swashes, namely step on leg to swash, 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 suspension ring, in the process constantly climbed, constantly change suspension ring.In prior art, leg is welded on the body of rod, after damage occurs, namely hanging ladder can not use, need to take workshop repair, this not only bothers very much, also work is caused and have impact on, in this device, leg is to be threaded on the body of rod, leg runs through the body of rod, it is fixed at offside nut, so as not in use, leg there will be rotation phenomenon, protect staff, and leg also sets up rubber case, rubber case arranges raised line, add and the frictional force of staff's sole, avoid staff's sole to skid, also staff is protected, rubber case inwall is also equipped with groove, it is to cooperate with tooth on the bottom land of circumferential groove, make not have between rubber case and leg to relatively rotate.
Further, being provided with groove in the groove of above-mentioned hook, the cell wall of groove is covered with salient point, when being hooked on cable, cable can be positioned at groove, arranges again salient point in groove, and such cable will not be easy to disengage in hook.
Further, the upper end of above-mentioned fixing bar is provided with two rotating handleses being oppositely arranged, and rotating handles is a straight-bar, and rotating handles is integrated with fixing bar to be connected.The turn of the convenient fixing bar of rotating handles, convenient fixing bar enters ground.
Further, above-mentioned fixing bar is provided with the helicla flute that the hand of spiral is consistent with stopping leaf.Fixing bar is that turn enters ground, arranges helicla flute so that fixing bar enters convenient.
The invention has the beneficial effects as follows:
(1) in this device, leg arranges a rubber case, rubber case arranges raised line again, adds the frictional force of sole and leg, when climbing, seldom there will be skidding；
(2) for threadeding between leg with the body of rod, after damage occurs in leg, changing a new leg, ladder can reuse so that maintenance is easily；
(3) groove is set in the groove linked up with, salient point is set in groove so that cable will not be easy to disengage from hook.
