Description
Technical field
The utility model belongs to electric power network technical field, particularly relates to a kind of for the special bearing tool of power transmission line steel pipe rod replacing insulator under electrified.
Background technology
The circuit of steel pipe pole has the advantages such as good looking appearance, floor space are little, shaft tower material is not easily lost, but also there is the shortcomings such as cost is high, maintenance inconvenience, transport inconvenience, applied to some extent in transmission line in recent years, but not very extensive, only have when minority area or special requirement and just set up this type of transmission line.Tradition live line working is installed, is safeguarded that insulating tool used and method of operation do not update to new standard.Particularly need when steel pipe pole cross-arm Head suspension suspension centre, because the similar cuboid component of steel pipe pole is succinct, cross-arm head is smooth and do not have installing hole, and hot line job is difficult to launch.The load entablature of conventional steel cast shaft tower live line working replacing insulator under electrified work tower head jig used is the gravity that level design is difficult to bear Great span, large load.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of special bearing tool of confession power transmission line steel pipe rod replacing insulator under electrified that can bear the gravity of Great span, greatly load.
The utility model realizes like this, a kind of for the special bearing tool of power transmission line steel pipe rod replacing insulator under electrified, this instrument comprises trapezoidal load crossbeam, this trapezoidal load crossbeam comprises parallel load entablature and load sill, and connect the oblique pull beam of load entablature and load sill, load sill lies in a horizontal plane in steel pipe pole cross-arm head upper strata, both sides are provided with equidistant adjustable elongated hole, for adjusting the position of installing needed for fastening bolt and the width adapting to steel pipe pole cross-arm head, it is parallel with load sill that one fastening sill is set, lie in a horizontal plane in steel pipe pole cross-arm head lower floor, both sides are provided with equidistant adjustable elongated hole to adapt to the width of steel pipe pole cross-arm head simultaneously, be fixed as one through adjustable elongated hole by fastening bolt between fastening sill and load sill.
Further, the two ends of load sill are provided with instrument hitch point, for hanging insulating tool, can turn on all kinds of insulating tool of convenient connection by hitch point bolt.
Further, in the framework of trapezoidal load crossbeam, arrange two reinforce cant beam.
Compared with prior art, beneficial effect is the utility model:
1, the utility model changes the just achievable events in operation that in the past need to have a power failure, and can carry out, improve power supply reliability on alive circuit;
2, the utility model can adapt to the installation of this area all 220 kilovolts and 66 KV transmission line steel pipe pole cross-arm heads, and the steel pipe type shaft tower transmission line being suitable for all Great span, large load, single conductor and multiple wire uses, and improves versatility;
3, while the utility model is arranged on steel pipe pole cross-arm head, also effectively increases live wire distance to the ground, air gap, the insulating coefficient enhancing insulating tool and insulation level, improve fail safe;
4, can improve when the utility model uses on dead line because coaster suspension centre is too low and cause insulator to install difficulty, setting fastening and difficulty of triping, improve ranges of operability.
Accompanying drawing explanation
Fig. 1 is the tool construction schematic diagram that the utility model embodiment provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
See Fig. 1, a kind of for the special bearing tool of power transmission line steel pipe rod replacing insulator under electrified, this instrument comprises trapezoidal load crossbeam, this trapezoidal load crossbeam comprises parallel load entablature 2 and load sill 7, and connect the oblique pull beam 3 of load entablature 2 and load sill 7, the two ends of load sill 7 are provided with instrument hitch point 3, for hanging insulating tool, can turn on all kinds of insulating tool of convenient connection by hitch point bolt.In the framework of trapezoidal load crossbeam, arrange two reinforce cant beam 8.Load sill 7 lies in a horizontal plane in steel pipe pole cross-arm head upper strata, both sides are provided with equidistant adjustable elongated hole 5, for adjusting the position of installing needed for fastening bolt and the width adapting to steel pipe pole cross-arm head, it is parallel with load sill 7 that one fastening sill 4 is set, lie in a horizontal plane in steel pipe pole cross-arm head lower floor, both sides are provided with equidistant adjustable elongated hole to adapt to the width of steel pipe pole cross-arm head simultaneously, are fixed as one between fastening sill 4 and load sill 7 by fastening bolt 6 through adjustable elongated hole.
Trapezoidal load crossbeam: trapezoidal load crossbeam is stressed maximum component in this cover instrument, for carrying from all vertical loads of wire, trapezoidal load crossbeam is reinforced cant beam 8 by 1 load entablature, 2,1 load sill, 7,2 oblique pull beams 1 and two and is formed.
Load entablature 2 lies in a horizontal plane in load sill 7 upper strata, utilizes oblique pull beam 1 and reinforce cant beam 8 to be rationally connected with load sill 7.Load sill 7 lies in a horizontal plane in steel pipe pole cross-arm head upper strata, and both sides are provided with equidistant adjustable elongated hole, for adjusting the position of installing needed for fastening bolt and the width adapting to steel pipe pole cross-arm head.Its two ends are provided with instrument hitch point 3, and for hanging insulating tool, hitch point bolt can turn on all kinds of insulating tool of convenient connection.Fastening sill 4: lie in a horizontal plane in steel pipe pole cross-arm head lower floor, both sides are provided with equidistant adjustable elongated hole to adapt to the width of steel pipe pole cross-arm head simultaneously.Utilize fastening bolt 6 to connect levels crossbeam, make the utility model firmly be located in steel pipe pole cross-arm head.Adjustable elongated hole, design is in load sill and appropriate location, fastening sill both sides, make this jig width adjustable, vertically penetrate fastening bolt and connect levels crossbeam, fastening bolt: using the development of high strength manganese steel material, for connecting load sill and fastening sill, vertically penetrating the adjustable elongated hole of load sill and fastening sill, this cover jig is made to keep balance, for carrying the uneven pulling force from producing in operation.Instrument hitch point: for hanging insulating tool, its bolt adopts high strength manganese steel material to manufacture can turn on all kinds of insulating tool of convenient connection.
