Abstract
The invention discloses a square cross arm, belonging to cross arms. The square cross arm structurally comprises a cross arm body, wherein the cross section of the cross arm body is square; two sides of the end part of the cross arm body, connected with a main rod, are respectively provided with a cross arm connecting plate; the cross arm connecting plates are welded on the main rod; the tail end of the cross arm body is provided with a sealing plate; the upper part of the tail end of the cross arm body is provided with a wire hanging plate; the lower part of the wire hanging plate is provided with a wire hanging ring; the wire hanging ring is provided with a hardware tool; and the upper part of the cross arm body is provided with a cross arm handrail. Compared with the prior art, the square cross arm has the characteristics that: when the square cross arm is examined and repaired, a worker can examine and repair the square cross arm by holding the cross arm handrail with a hand so as to bring the convenience to the worker; and the cross arm is fixed with the main rod by virtue of the cross arm connecting plate, thus the mounting process is convenient. Therefore, the square cross arm has excellent popularization and application values.
Description
Technical field
The present invention relates to a kind of cross-arm, especially a kind of for the square cross arm on the power transmission line steel pipe rod.
Background technology
Along with the Chinese society rapid development of economy, electricity need load progressively increases, and ultra-high-tension power transmission line enters the city has become development trend.That steel pipe pole has is simple in structure, intensity is high, handsome in appearance, the process-cycle is short, floor space is few, transportation and the advantage such as save time easy for installation, being applicable to the utmost point such as different voltages of multiloop joint uses, coordinate mutually with the modern city development, be widely used in the construction of 10-220kv transmission line of electricity.But because the cross-arm that arranges on the steel pipe pole directly is connected by welding manner with mobile jib, make troubles for the installation of cross-arm, in addition, because without handrail, when overhauling, the staff can only hold cross-arm tightly by hand on the cross-arm, just can overhaul, make troubles to the staff.At present, good solution is not also arranged.
Summary of the invention
Technical assignment of the present invention is to provide a kind of square cross arm for above-mentioned deficiency of the prior art, this a kind of square cross arm has when overhauling, the staff can overhaul by holding the cross-arm handrail, bring convenience to the staff, cross-arm is fixed by cross-arm junction plate and mobile jib, characteristics easy for installation.
The technical solution adopted for the present invention to solve the technical problems is: it comprises the cross-arm body, described this body section of cross-arm is square, the both sides, end that described cross-arm body links to each other with mobile jib are respectively arranged with the cross-arm junction plate, described cross-arm junction plate is welded on the mobile jib, the end of described cross-arm body is provided with hush panel, the upper end of cross-arm body is provided with thread gripping-board, the thread gripping-board bottom is provided with the hanging wire ring, be provided with gold utensil on the described hanging wire ring, the top of described cross-arm body is provided with the cross-arm handrail, be provided with the cross-arm stiffened panel on the described cross-arm junction plate, an end of described cross-arm stiffened panel and mobile jib welding.
Described cross-arm body and cross-arm junction plate fix by bolt.
A kind of square cross arm of the present invention is compared with existing technology, have following outstanding beneficial effect: cross-arm top is provided with the cross-arm handrail, when overhauling, the staff can overhaul by holding the cross-arm handrail, brings convenience to the staff, cross-arm and mobile jib junction are provided with the cross-arm junction plate, cross-arm is fixed by cross-arm junction plate and mobile jib, and is easy for installation, alleviates staff's labour intensity, reasonable in design, the characteristics such as simple in structure.
Description of drawings
Accompanying drawing 1 is that a kind of master of square cross arm looks the sectional structure schematic diagram;
Accompanying drawing 2 be a kind of square cross arm overlook the sectional structure schematic diagram;
Description of reference numerals: 1, thread gripping-board, 2, the cross-arm handrail, 3, hush panel, 4, the cross-arm junction plate, 5, mobile jib, 6, bolt, 7, the cross-arm stiffened panel, 8, the cross-arm body, 9, gold utensil, 10, the hanging wire ring.
The specific embodiment
Explain below 6 pairs of a kind of square cross arms of the present invention of accompanying drawing are done with reference to Figure of description 1.
A kind of square cross arm of the present invention, its structure comprises cross-arm body 8, described cross-arm body 8 cross sections are square, the both sides, end that described cross-arm body 8 links to each other with mobile jib 5 are respectively arranged with cross-arm junction plate 4, described cross-arm junction plate 4 is welded on the mobile jib 5, the end of described cross-arm body 8 is provided with hush panel 3, the upper end of cross-arm body 8 is provided with thread gripping-board 1, thread gripping-board 1 bottom is provided with hanging wire ring 10, be provided with gold utensil 9 on the described hanging wire ring 10, be used for suspension insulator, the top of described cross-arm body 8 is provided with cross-arm handrail 2, makes things convenient for cross-arm body 8 to install.
Described cross-arm body 8 fixes by bolt 6 with cross-arm junction plate 4.
Be provided with cross-arm stiffened panel 7 on the described cross-arm junction plate 4, an end of described cross-arm stiffened panel 7 and mobile jib 5 welding.Increase the working strength of cross-arm junction plate 4.
When cross-arm was overhauled, the staff operated by the cross-arm handrail 2 of holding cross-arm top.
Except the described technical characterictic of manual, be the known technology of those skilled in the art.
