The sub-cat ladder of Portable insulation
The utility model relates to a kind of tools manufacturing technology field, and specifically one is applied to the sub-cat ladder of Portable insulation of pendency (compound) insulator.
There is insulator miscellaneous to occur on transmission line of electricity year by year, in maintenance process, climb up that to climb down be all utilize the climbing of insulator ladder body, easily injury insulator itself, particularly composite insulator, insulator umbrella is many by meeting material, as silica gel etc., very easily damages full skirt; And on shaft tower the position of reserved upper and lower insulator, upper and lower space constraint and the requirement such as protection full skirt is not injured, upper and lower insulator spindle does not have favourable support point, require great effort very much, and security risk is large.
Utility model content
Technical problem to be solved in the utility model is to provide the sub-cat ladder of a kind of Portable insulation, can, not touched insulator, not injure insulator, and have the strong point on hand with on pin, safety labor-saving up and down on cross-arm and wire by this cat ladder.
The utility model solves the problems of the technologies described above with following technical scheme:
The sub-cat ladder of a kind of Portable insulation of the utility model, it is connected to form by least three sections of terraced bodies 1, connected by foldable connecting part 2 between two sections of adjacent terraced bodies, every section of ladder is evenly equipped with the draw-in groove 6 for installation foot pedal 7 with it, is connected and can realizes folding between foot rest 7 with draw-in groove 7 by set bolt 4; In the bottom of lowermost ladder body, "eight" shape cable clamping interface 10 is installed, connect removable cross bar 8 on the top of uppermost ladder body by rotating bolt 3, the top of the two ends of removable cross bar 8 and uppermost ladder body is connected with the binding strap 9 for being connected with cross arm of tower.
Described foldable connecting part 2 is separately fixed at the terraced body termination connected card by two panels is connected and composed by hinge axis, and set bolt 4 is housed to be locked.
Described ladder as box section, and adopts high hardness alloy material to make.
The utility model portable folding cat ladder tool has the following advantages:
1, use alloy material to make, be convenient for carrying, cable clamping interface be stuck on wire as fixed point, top is fixed on cross-arm brilliance steel, and people just can prolong on the upper and lower cross-arm of this ladder and wire, does not touch insulator, do not injure feel insulator, and have the strong point on hand with on pin, safety labor-saving;
2, use the utility model cat ladder dangle up and down (compound) insulator string time, working strength reduces greatly, climbs up and down without the need to the weight with the hands bearing self, and the strength major part that staff's both hands bear is transferred on leg, up and down freely;
3, greatly reduce the risk that staff damages, sprains, falls, safety factor is improved greatly;
4, instrument lighter in weight, terraced body and foot rest collapsible, easy to carry, occupy little space, easily take care of;
5, structure is simple, easy to operate;
6, the utility model cat ladder also can solve shaft tower, and particularly steel pipe column foot nail is overhead too high, the problem that personnel's inconvenience is upper and lower, and be fixed on pin nail position with this terraced upper end, lower end is fixed on ground, and personnel just can be easily upper and lower.

Detailed description of the invention
As shown in Figure 1, the sub-cat ladder of the utility model Portable insulation by three sections (as required, also can be more than three sections) high hardness alloy material make rectangular tube-type ladder body 1 be connected to form, connected by foldable connecting part 2 between two sections of adjacent terraced bodies, the card that described foldable connecting part 2 can be separately fixed at by two panels the terraced body termination connected is connected and composed by hinge axis 11, and to be coordinated with bolt hole 5 by set bolt 4 and be locked, also the foldable connecting part of other structure can be adopted, as long as terraced body 1 can be folded, deployable and fix during use.
The utility model is evenly equipped with the draw-in groove 6 for installation foot pedal 7 with it at every section of ladder, draw-in groove 6 is fixed on by welding manner with it ladder, be connected by set bolt 4 between foot rest 7 with draw-in groove 6 and can realize folding, in use, foot rest 7 is fixed on draw-in groove 7 by set bolt 4 with it after ladder launches, when non-working condition, set bolt 4 can be unclamped, foot rest 7 is turned to and is close to terraced body, be easy to carry; In the bottom of lowermost ladder body, "eight" shape cable clamping interface 10 is installed, is stuck in the wire of different model for terraced body lower end.Removable cross bar 8 is connected by rotating bolt 3 on the top of uppermost ladder body, removable cross bar 8 can as required along terraced its position of body up-down adjustment, and the top of the two ends of removable cross bar 8 and uppermost ladder body is connected with the binding strap 9 for being connected with cross arm of tower.
During use, take the rotating bolt 3 on two foldable connecting parts 2 apart, tighten rotating bolt 3 after launching three sections of terraced bodies 1 again and three sections of terraced bodies are formed a fixed connection; Cable clamping interface 10 is stuck on the wire of wire clamp mouth, uppermost ladder removable cross bar 8 is with it moved to after cross arm of tower place is fixed and is locked by rotating bolt 3, be fixed on cross-arm by the binding strap 9 at two ends and the binding strap 9 at top by cat ladder again, staff just can carry out operation along the upper and lower cross-arm of ladder and wire.
