Description
Technical field
The utility model belongs to the anticorrosion of iron tower of power transmission line stone bolt and antitheft field, especially a kind of iron tower of power transmission line anchor bolt protective cap.
Background technology
Protective cap cast by stone bolt is after losing stone bolt or nut long-play, loosen the accident of falling tower caused in order to preventing, is to the important flow process that shaft tower tower boots are protected after electric power line pole tower group is stood.
According to the storehouse requirement of State Grid Corporation of China's project of transmitting and converting electricity technological standards, cast in process at protective cap, have very high requirement to protective cap with water, sand, stone, cement.And prevention & protection crown portion construction technology is especially added to the strict demand of " protective cap end face should leave drainage grade, end face must not ponding ".Protective cap upper surface should carry out receipts light 3-4 time before solidifying, and casts end and need receive light 2 times, receives once after 2 hours thin.Rear striking time cast by protective cap must not be less than 8 hours.Protective cap should carry out maintenance on request.These requirements, main purpose prevents from casting in process at protective cap, selects not pass a test and construction technology is not in place causes protective cap main body ponding due to raw material, causes the corrosion of tower material, affect circuit security of operation.
The ratio that transmission line of electricity due to current erection is positioned at mountain region is higher, casts protective cap in mountain region, and raw material transport inconvenient and duration is nervous to cause part unit in charge of construction to adopt undesirable rubble, silt particle to fill casting protective cap.And to the technological standards that various needs " slow work fine work " just can reach; part unit in charge of construction especially with after building initial set namely form removal go to the village fair processing, do not note protective cap end face discharge structure; for these newly-built transmission lines of electricity leave potential safety hazard, the corrosion of generation can have a strong impact on the application life of transmission line of electricity.
These potential safety hazards casting improper existence due to protective cap have:
1, protective cap body material is inferior, causes protective cap to ftracture, infiltration, and then causes tower material and stone bolt corrosion.
2, protective cap construction technology operating difficulties, due to the limitation of field construction, is difficult to reach the requirements such as the wiping one's face of technological requirement, maintenance, causes protective cap total quality can not meet technological requirement, affect the protective cap life-span.
3, because the technique level of constructor exists deviation, relevant criterion requires to be difficult to realize, and part protective cap top and the oblique material of side, main volume of timber water, cause because constructor's technological level is low substantially.
4, construction process is improper.Namely department's circuit carries out the phenomenon of protective cap construction after there is tower erection, after shaft tower is stressed, bottom column boots local torsion, causes the avalanche of protective cap cracking.
The existence of these potential safety hazards, affects the safe operation of transmission line of electricity dramatically.
Utility model content
Technical problem to be solved in the utility model is the defect overcoming the existence of above-mentioned prior art; the iron tower of power transmission line anchor bolt protective cap that a kind of structure is improved is provided, to simplify the construction technology that it is cast, convenient construction; and guarantee construction quality, meet protection requirement.
For this reason; the utility model adopts following technical scheme: a kind of iron tower of power transmission line anchor bolt protective cap; comprise tower base plate and the stone bolt running through tower base plate; described stone bolt overlaps the second nut having the circular plain cushion be pressed on tower base plate, be pressed in the first nut on plain cushion and be pressed on the first nut; the thread segment of stone bolt is positioned at above plain cushion; it is characterized in that
On the thread segment of described stone bolt, connection one is pressed in the central point fixed cover on the second nut, and described central point fixed cover, the second nut, the first nut and plain cushion overcoat have a containment vessel, the open top of this containment vessel, and bottom is pressed on tower base plate; There is the space of 2-10mm between the outermost end of described central point fixed cover and the inwall of containment vessel, in the cavity in containment vessel, be full of rapid solidification filler.Center fixed cover is consistent for the center at the center with stone bolt that make containment vessel, avoids containment vessel eccentric.Containment vessel plays mould action when pouring into a mould rapid solidification filler, makes rapid solidification filler rapid solidification in containment vessel, casts and plays some protective effects to filler afterwards.The space of 2-10mm can be avoided containment vessel to be enclosed within stone bolt Shang Shiyu center fixed cover and produce friction, also within the scope of the allowable error that the center of guarantee containment vessel is consistent with the center of stone bolt.
Further, described central point fixed cover comprises cylindrical body and many circumferences and is distributed in positioning strip on body periphery wall, there is the space of 2-10mm between the outer end of described positioning strip and the inwall of containment vessel.Body is used for being connected with stone bolt, and positioning strip is consistent for the center at the center with stone bolt that make containment vessel, avoids containment vessel eccentric.
Further, many described positioning strips are symmetric, and make the center uniformity of the center of containment vessel and stone bolt high.
Further, the external diameter of described body, the first nut and the second nut is all consistent, and is less than the external diameter of plain cushion.
Further, described containment vessel foot bolt above Ground, the top of rapid solidification filler mulched ground foot bolt, uses rapid solidification filler coated completely by stone bolt.
Further, the material of described containment vessel is plastics, because containment vessel mainly plays mould action, therefore to the not too large requirement of the intensity of containment vessel, can reduce construction cost and easy to make with plastics.
Further, the material of central point fixed cover is metal, and after rapid solidification filler solidifies, central point fixed cover also plays booster action to the structure of stone bolt, therefore adopts metal to make.
Protective cap of the present utility model has bolt waterproof, and isolated air, prevents the effect that bolt is oxidized, after protective cap solidifies, also possess the function preventing stone bolt upper cap nut from losing.
Accompanying drawing explanation
Fig. 1-2 is the structural representation of the utility model iron tower of power transmission line anchor bolt protective cap.
