Abstract
The utility model discloses a rust -resistant metal protection cap of transmission line iron tower rag bolt. Present protective cap is cast improper meeting and is had the potential safety hazard, and very big degree ground is influencing transmission line's safe operation. The utility model discloses a characterized in that, rag bolt on connect one and be located the connecting piece between tower base board and flat the pad, the connecting piece, it is flat that fill up and the nut is covered with metal protection cover outward, the top of this metal protection cover is sealed, the bottom is connected with the connecting piece, the metal protection covers interior vacuole formation. The utility model discloses a metal protection cover plays waterproof effect to the bolt, avoids the bolt to rust with water direct contact, outside protective cover installs the back, also possesses the function that prevents the rag bolt upper cap nut and lose, need not adopt the concrete to cast, satisfy under protection requirement's the prerequisite simple structure, simple to operate.
Description
Technical field
This utility model belongs to iron tower of power transmission line foundation bolt anticorrosion and antitheft field, especially a kind of iron tower of power transmission line foundation bolt anti-rust metal protective cap.
Background technology
Concrete protective cap cast by foundation bolt is to prevent because loosening the accident of falling tower caused after losing foundation bolt or nut (nut) long-play, is the important flow process after electric power line pole tower group is stood, shaft tower tower boots protected.
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, protective cap had significantly high requirement 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 hydrops ". Protective cap upper surface should carry out receiving light 3-4 time before solidification, casts end and need to receive light 2 times, receives once thin after 2 hours. Protective cap is cast rear striking time and be cannot be less than 8 hours. Protective cap should carry out maintenance on request. These requirements, main purpose is to prevent from casting in process at protective cap, does not pass a test due to material choice and construction technology is not in place causes protective cap main body hydrops, cause tower material corrosion, affects circuit and runs safety.
The ratio that transmission line of electricity owing to currently setting up is positioned at mountain region is higher, casts protective cap in mountain region, and raw material transport inconvenience and duration anxiety cause that part unit in charge of construction adopts undesirable rubble, silt particle to fill and casts protective cap. And to the technological standards that various needs " slow work fine work " can be only achieved; 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; leaving potential safety hazard for these newly-built transmission lines of electricity, the corrosion of generation can have a strong impact on the service 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, in turn results in tower material and foundation bolt corrosion.
2, protective cap construction technology operating difficulties, due to the limitation of field construction, it is difficult to reaches 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, owing to the technique level of workmen exists deviation, relevant criterion requires to be difficult to, and part protective cap top and the oblique material of side, main volume of timber water cause owing to workmen'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 stress, bottom column boots local torsion, causes protective cap cracking avalanche.
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 above-mentioned prior art to exist; a kind of iron tower of power transmission line foundation bolt anti-rust metal protective cap is provided; it need not adopt concrete to cast, and under the premise that satisfied protection requires, simplifies structure and installation.
For this, this utility model adopts the following technical scheme that: iron tower of power transmission line foundation bolt anti-rust metal protective cap, including tower base plate and the foundation bolt running through tower base plate, described foundation bolt is cased with plain cushion and the nut being pressed on plain cushion, it is characterised in that
Connecting a connector between tower base plate and plain cushion on described foundation bolt, described connector, plain cushion and nut are covered with a protective cover, the top seal of this protective cover, and bottom is connected with connector, protective cover interior formation cavity.
Protective cover, except the bolt in protective cover, nut, also functions to anti-theft function. Cavity is beneficial to the steam natural air drying in cover.
Further, the bottom of described protective cover adopts screw thread to be connected with connector, and what make between the two is easy to assembly and firm.
Further, the thread segment of described foundation bolt is positioned at above plain cushion, and thread segment is for being connected with nut.
Further, described nut has two, strengthens fixing bolt.
Further, described protective cover is barrel-shaped, and described plain cushion and connector are circular, convenient processing.
Further, the external diameter of described nut is less than plain cushion, and the external diameter of described plain cushion is less than connector.
Further, described protective cover foot bolt above Ground, it is provided that bigger cavity, is beneficial to the steam natural air drying in cover.
Further, the material of described protective cover is rustless steel or weathering steel, and protective action is better.
Further, the material of described connector is rustless steel or weathering steel so that it is and the connection between protective cover is more firm.
Further, described protective cover be provided externally with antitheft unidirectional screw thread, tighten for back-up wrench.
Bolt is played the effect of waterproof by protective cover of the present utility model, it is to avoid bolt directly contacts with water and gets rusty; After outside protective covers is installed, also possesses the function preventing foundation bolt upper cap nut from losing; Concrete need not be adopted to cast, under the premise that satisfied protection requires, simple in construction, easy for installation.
