Abstract
The invention relates to a technology largely reducing manufacturing material of a steel cap and especially relates to a needle-type composite insulator special steel cap. According to the technical scheme, the upper part of the steel cap is oval with two ears, and the lower part is designed to be in a hollow cylindrical shape. The distance a1 between the two ears of the oval is designed to be not greater than 65 mm, a2 between the two ears is designed to be not greater than 35 mm, and a3 of the two ears is designed to be not greater than 10 mm. Each ear is provided with a round screw hole, and the distance a4 between the two screw holes is designed to be not greater than 50 mm. The length b1 of the hollow cylinder at the lower part of the steel cap is designed to be not greater than 30 mm. The outer diameter b2 of the bottom of the hollow cylinder at the lower part of the steel cap is designed to be not greater than 33 mm. The inner diameter b3 of the hollow cylinder at the lower part of the steel cap is designed to be not greater than 25 mm. The oval design with the two ears is convenient for use, and the manufacturing material of the steel cap is greatly reduced. The technical conditions are as follows: hot galvanizing of the steel cap meets the JB/T8177 standard; the thickness of a zinc layer is greater than 86 [mu]m; hot galvanizing of an inner hole and a spigot are done later; and the rated bending load is greater than 5 kN.
Description
Technical field
The present invention relates to a kind of steel cap that is substantially reduced and prepare the technology of material, particularly to a kind of needle type composite insulator special-purpose steel cap.
Background technology
In recent years, along with the increase of composite insulator producer, the surface insulation performance of insulator also, constantly before degenerating not, occurs that accident is the most continuous.The use of composite insulator is in the case of ensureing normal use, and the component demand amount such as steel cap is the most all greatly improved.Due to for insulator industry, its not only prescription the highest, and demand is infinitely great, and supply falls short of demand in the most raw-material use, thus affects the production of parts, affect the shipment of composite insulator, and impact society normally uses.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, it is provided that the technology of material prepared by a kind of steel cap that is substantially reduced, scene need not change production stage, only need to change size to improve production yields, to reduce material consumption.
For reaching above-mentioned purpose, the technical solution used in the present invention is as follows:
A kind of needle type composite insulator special-purpose steel cap, it is characterized in that: the top of steel cap is oval ears shape, bottom is designed as hollow cylindrical, size a1 between the top ellipse ears of steel cap is designed as less than or equal to 65mm, a2 between the top ellipse ears of steel cap is designed as less than or equal to 35mm, the top ellipse ears a3 of steel cap is designed as less than or equal to 10mm, both sides ears are respectively provided with circular screwhole, between two screws, size a4 is designed as being less than and waits 50mm, the lower hollow body length b1 of steel cap is designed as less than or equal to 30mm, the hollow circuit cylinder bottom surface overall diameter b2 of steel cap bottom is designed as being less than or equal to, the lower hollow cylinder interior diameter b3 of steel cap is designed as being less than or equal to, due to its oval convenient use of ears shape design, it is substantially reduced steel cap and prepares material.
Preferably, described steel cap top is set to oval ears shape, and both sides ears are respectively provided with circular screwhole.
Preferably, described steel cap bottom is set to hollow cylindrical, and convenient other structures are connected with steel foot etc..
Preferably, it is set to crescent between ellipse ears both sides, the top screw of described steel cap.
Preferably, the galvanizing that designing technique condition is steel cap of described steel cap should meet JB/T8177 standard, and zinc coating thickness is more than 86 μm, endoporus, seam galvanizing post-treatment, and specified bend loading is more than 5kN.
The present invention solves defect present in background technology, the composite insulator more reliable performance that the composite insulator that the technology of a kind of needle type composite insulator special-purpose steel cap that the present invention provides is produced is produced than general composite insulator steel cap, safer, it is greatly saved the most exactly and prepares material.
Accompanying drawing explanation
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 Fig. 2 is the structural representation of the preferred embodiments of the present invention；
Detailed description of the invention
Presently in connection with drawings and Examples, the present invention is further detailed explanation, and these accompanying drawings are the schematic diagram of simplification, and the basic structure of the present invention is described the most in a schematic way, and therefore it only shows the composition relevant with the present invention.
nullAs shown in Fig. 1 Fig. 2，A kind of needle type composite insulator special-purpose steel cap of the present invention includes that the top of described steel cap is oval ears shape，Bottom is designed as hollow cylindrical，Size a1 between the top ellipse ears of steel cap is designed as less than or equal to 65mm，A2 between the top ellipse ears of steel cap is designed as less than or equal to 35mm，The top ellipse ears a3 of steel cap is designed as less than or equal to 10mm，Both sides ears are respectively provided with circular screwhole，Between two screws, size a4 is designed as being less than and waits 50mm，The lower hollow body length b1 of steel cap is designed as less than or equal to 30mm，The hollow circuit cylinder bottom surface overall diameter b2 of steel cap bottom is designed as being less than or equal to，The lower hollow cylinder interior diameter b3 of steel cap is designed as being less than or equal to，Due to its oval convenient use of ears shape design，It is substantially reduced steel cap and prepares material，Described steel cap top is set to oval ears shape，Both sides ears are respectively provided with circular screwhole，It is set to crescent between ellipse ears both sides, the top screw of described steel cap，Described steel cap bottom is set to hollow cylindrical，It is convenient that other structures are connected with steel foot etc..Technical conditions: the galvanizing of steel cap should meet JB/T8177 standard, zinc coating thickness is more than 86 μm, endoporus, seam galvanizing post-treatment, and specified bend loading is more than 5kN.
Desirable embodiment according to the present invention is enlightenment above, and by above-mentioned description, related personnel can carry out various change and amendment completely in the range of without departing from this invention technological thought.The content that the technical scope of this invention is not limited in description, it is necessary to determine technical scope according to right.
