Description

Power transmission lines overhauling ladder
Technical field
The present invention relates to a kind of maintenance ladders, and in particular to power transmission lines overhauling ladder.
Background technique
Currently, transmission line of electricity in restringing insulator, needs to enter side of wire, all none is effective always Tool, conventionally employed tool uses with significant limitation, can only be hung in one direction, so just It can only carry out the work in one direction, the flexibility used is poor.
Summary of the invention
The technical problem to be solved by the present invention is to conventionally employed tools to use with significant limitation, can only Hung, just can only be carried out the work in one direction so in one direction, the flexibility that uses difference, and it is an object of the present invention to provide Power transmission lines overhauling ladder, conducting wire hanging point can rotate left and right, and are able to carry out left and right adjusting in this way and hang left direction or the right side Conducting wire on edge direction, so just can, solve the problems, such as that the problem of because of direction can only carry out the work in one direction.
The present invention is achieved through the following technical solutions:
Power transmission lines overhauling ladder, including two support rods disposed in parallel, between two support rods alongst It is successively vertically connected with intermediate strut, the same end of two support rods is connected with cross-arm hook, hangs down between the other end of two support rods It is direct-connected to have two gag lever posts disposed in parallel, two struts, two struts and limit are connected on the gag lever post of cross-arm hook Angle between bar is 45-60 °, and the top of two struts is directed towards inclination, the plane where two struts and two supports The angle between plane where bar is in 25-30 °, is connected with the supporting plate vertical with support rod, supporting plate between the top of two struts On be equipped with wire hook, wire hook can be rotated up 360 ° of sides.
Maintenance ladder of the invention, conducting wire hanging point can rotate left and right, and are able to carry out left and right adjusting in this way and hang the left side Conducting wire on direction or the right direction, so just can, solve the problems, such as can only to carry out the work in one direction because of direction Problem.Ladder of the invention when in use, realizes that service personnel carries ladder and climbs to the top end of electric pole, then will be on ladder Cross-arm be hung on electric pole cross-arm, then wire hook rides upon on the conducting wire of side, and operator passes through ladder Intermediate strut just can climb to conducting wire the place for needing replacing insulator from the cross-arm of electric pole, again will after the completion of replacement Ladder is removed from cross-arm;Wire hook can be rotated up 360 ° of sides, in this way in the replacement for completing side wire insulation Later, wire hook is removed from conducting wire, then rotates 180 ° of wire hook and make hook towards the other side, this energy convenient to both is hung It is located on the conducting wire of the other side, allows to carry out left and right adjusting by the flexible design of wire hook convenient for being hung on difference On the conducting wire of side, time of the transmission line of electricity when replacing insulator is shortened;It is to pass through behaviour when ladder to be hung on conducting wire One end of ladder is lifted as personnel, then vacantly mobile ladder is that wire hook is hung on conducting wire, is easy to hang sky in this way, need more Operation can just be hung up several times, increase the time hung;Design of the present invention by strut and the plane where two struts Angle between the plane where two support rods is in 25-30 °, therefore when hanging conducting wire, can be first fastened on conducting wire In the 25-30 ° of angle formed between strut plane and support rod plane, then to operator direction reverse drawing ladder, lead in this way Line is just hung on wire hook along the track of strut, is greatly saved conducting wire and is hung the time, improves efficiency.
Further include safety hoop, safety rope and safety belt are connected in safety hoop, the end of safety rope is connected by latch closure On support rod, the end of safety belt is connected with locking device, and when operator overhauls, safety hoop is mounted on electric wire On bar, then safety belt is fastened on the waist of operator, is connected in service personnel and ladder, electric pole by safety hoop Together, the safety in maintenance process is greatly improved.
It is arranged with insulating sheath at the hook of wire hook, reduces the abrasion to conducting wire.
Blocking device is installed on the cross-arm hook, it being capable of more efficient, safety.
Support rod, intermediate strut are all made of aluminum alloy materials and are made, and reduce compared to quality for traditional ladder, light spirit Living, a people can be with independent operation.
Compared with prior art, the present invention having the following advantages and benefits:
1, power transmission lines overhauling ladder of the present invention, conducting wire hanging point can rotate left and right, and be able to carry out left and right adjusting extension in this way If the conducting wire on left direction or the right direction, so just can, solve the problems, such as to carry out in one direction because of direction The problem of work;
2, safety hoop is mounted on electric pole when operator overhauls by power transmission lines overhauling ladder of the present invention On, then safety belt is fastened on the waist of operator, service personnel and ladder, electric pole are connected in one by safety hoop It rises, greatly improves the safety in maintenance process;
3, power transmission lines overhauling ladder of the present invention is arranged with insulating sheath at the hook of wire hook, reduces to conducting wire Abrasion, the cross-arm are linked up with and are equipped with blocking device, can be more efficient, safe, and support rod, intermediate strut are all made of aluminium alloy Material is made, and reduces compared to quality for traditional ladder, light and flexible a, people can be with independent operation.
