Abstract

The utility model belongs to the technical field of electric power overhaul apparatus and discloses a multifunctional insulated ladder. The main technical characteristics are that the multifunctional insulated ladder comprises cross rods and vertical rods. The upper parts of the vertical rods are provided with outer fixed holes. Hook rods with inner fixed holes are connected with the vertical rods. A plurality of outer fixed holes are matched with the inner fixed holes. When using the multifunctional insulated ladder provided by the utility model, the connection length of the hook rods with the vertical rods is adjusted according to the height of a climbing ladder on a steel tube rod, the hook rods and the vertical rods are connected to be a whole body through the outer fixed holes and the inner fixed holes, then the hook rods are hung on the steel tube rod climbing ladder, and the staff can climb up and down successfully. The multifunctional insulated ladder can be used for steel tube rod maintenance and the replacement of an insulator in a 110kV to 220kV environment, a problem of difficult climbing in the process of steel tube rod overhaul maintenance is solved, the multifunctional insulated ladder can be applied to steel tube rod of various climbing ladders, the working efficiency of maintenance work can be raised, the labor intensity is reduced, and the security of work is raised significantly.

Description

The multifunction insulating ladder
Technical field
The utility model belongs to electric power overhaul utensil technical field, relates in particular to a kind of multifunction insulating ladder.
Background technology
Development along with Development of China's Urbanization, steel pipe pole with succinctly attractive in appearance, take up an area of few, in the construction of line of cities and towns, generally adopt, because the position that steel pipe pole sets up all is in the city or cities and towns periphery, it all is the movable ratio of people place more frequently, for preventing that the unrelated person climbing from causing danger, it is very high that the cat ladder of steel pipe pole is all installed, generally all apart from about 1.8 meters-2.3 meters on ground, the maintainer need jump just can catch below cat ladder, the smooth pin of steel pipe pole can't be borrowed power, and personnel's climbing that arm strength is little is very difficult, often needs 2 people to cooperate could climb mutually.If adopt common ladder, the one, volume is big, uses inconvenience, and the 2nd, common ladder props up on steel pipe pole unstable, slides easily.Be easy to cause in operating personnel's the work and pound the phenomenon of hurting sb.'s feelings, have potential safety hazard.In addition, the raw material of composite insulator porcelain patticoat are silicon rubber all, have excellent electrical insulation properties, but its mechanical strength are low, up and down in the process, can cause direct damage or internal injury along synthetic insulator to insulator the operating personnel.
The utility model content
The technical problems to be solved in the utility model just provide a kind of can be easily steel pipe pole up and down, quick and easy for installation, use the multifunction insulating ladder of safety.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise cross bar and montant, the top of described montant is provided with outer fixing hole, and the shank of fixing hole is connected with montant in having, and outer fixing hole and interior fixing hole are be complementary a plurality of.
Its additional technical feature is: described cross bar is provided with carrying bolt; The top of described carrying bolt is with rubber cap; Described cross bar is provided with the adjusting bolt; Described adjusting bolt is two.
When the multifunction insulating ladder that the utility model provides uses, adjust the length that is connected of shank and montant according to the height of cat ladder on the steel pipe pole, connect by outer fixing hole and interior fixing hole and to be one, then shank is hooked on the steel pipe pole cat ladder, the staff can be smoothly about.And the cross bar of lower end is provided with carrying bolt, makes the multifunction insulating ladder be connected the back with cat ladder in same plane, makes things convenient for the staff to climb.Carrying bolt top cover rubber cap increases friction, slides when preventing from climbing.The cross bar of upper end is provided with the adjusting bolt, when rolling off the production line operation, regulating bolt with two firmly is fixed on the shaft tower cross-arm, the operating personnel uses multi-functional maintenance ladder along synthetic insulator operation up and down, the operating personnel can not touch synthetic insulator in the process up and down, the phenomenon of synthetic insulator can not occur damaging, reach safety and operation purpose easily.The multifunction insulating ladder that the utility model provides namely can be used for steel pipe pole maintenance difficulty can also be used for 110kV-220kV replacing insulator work, has solved in the tubular pole repair and maintenance process problem of climbing difficulty; Can be applicable to the tubular pole of various cat ladders, can improve the upkeep operation operating efficiency, reduce labour intensity, significantly improve operational security.
Description of drawings
Fig. 1 is the structural representation of the utility model multifunction insulating ladder.
Embodiment
Be described further below in conjunction with the structure of accompanying drawing to the utility model multifunction insulating ladder.
As shown in Figure 1, the utility model multifunction insulating ladder comprises cross bar 1 and montant 2, the top of montant 2 is provided with outer fixing hole 3, the shank 5 of fixing hole 4 is connected with montant 2 in having, outer fixing hole 3 is a plurality of for what be complementary with interior fixing hole 4, and the cross bar 1 of lower end is provided with carrying bolt 6, and the top of carrying bolt 6 is with rubber cap, the cross bar 1 of upper end is provided with regulates bolt 7, and regulating bolt 7 is two.
When the multifunction insulating ladder that the utility model provides uses, adjust the length that is connected of shank 5 and montant 2 according to the height of cat ladder on the steel pipe pole, connect by outer fixing hole 3 and interior fixing hole 4 and to be one, then shank 5 is hooked on the steel pipe pole cat ladder, the staff can be smoothly about.And the cross bar 1 of lower end is provided with carrying bolt 6, makes the multifunction insulating ladder be connected the back with cat ladder in same plane, makes things convenient for the staff to climb.Carrying bolt 6 tops cover rubber cap increases friction, slides when preventing from climbing.The cross bar 1 of upper end is provided with regulates bolt 7, when rolling off the production line operation, regulating bolt 7 with two firmly is fixed on the shaft tower cross-arm, the operating personnel uses multi-functional maintenance ladder along synthetic insulator operation up and down, the operating personnel can not touch synthetic insulator in the process up and down, the phenomenon of synthetic insulator can not occur damaging, reach safety and operation purpose easily.The multifunction insulating ladder that the utility model provides namely can be used for steel pipe pole maintenance difficulty can also be used for 110kV-220kV replacing insulator work, has solved in the tubular pole repair and maintenance process problem of climbing difficulty; Can be applicable to the tubular pole of various cat ladders, can improve the upkeep operation operating efficiency, reduce labour intensity, significantly improve operational security.
Protection range of the present utility model not only is confined to above-described embodiment, as long as structure is identical with the utility model multifunction insulating ladder structure, just drops on the scope of the utility model protection.

Claims (1)

1. the multifunction insulating ladder comprises cross bar and montant, it is characterized in that: the top of described montant is provided with outer fixing hole, and the shank of fixing hole is connected with montant in having, and outer fixing hole and interior fixing hole are be complementary a plurality of.
