Abstract
The utility model discloses a kind of Novel power transmission power line steel tuble pole, comprise steel pipe pole mobile jib, the external surface of described steel pipe pole mobile jib is provided with at least one perforation group, and described perforation group is included in the first perforation and second that described steel pipe pole mobile jib external surface is oppositely arranged and bores a hole; Also comprise and described perforation group cross-arm connecting plate one to one, one end of described cross-arm connecting plate penetrates steel pipe pole mobile jib from described first and then passes described steel pipe pole mobile jib from described second, and described cross-arm connecting plate is welded to connect at described steel pipe pole mobile jib; Such structure is adopted to greatly reduce structural complexity, and run through steel pipe pole mobile jib because of cross-arm connecting plate instead of be directly welded to steel pipe pole mobile jib, the stress that such structure can offset part cross-arm root is concentrated, avoid stressedly concentrating on situation steel pipe pole mobile jib causing partial buckling, structure is simple, stress distribution is reasonable, and effectively can improve installation effectiveness, reduce costs.
Description
Technical field
The utility model relates to a kind of power transmission line steel pipe rod.
Background technology
The connected mode that transmission of electricity steel pipe pole cross-arm is conventional has connecting plate to put more energy into and Flange joint two kinds.Connecting plate employing two block plate of putting more energy into is joined 4 ~ 8 pieces of stiffeners and is soldered to mobile jib, Flange joint adopts companion flange and one week some stiffener to be soldered to supervisor, both all need a greater number stiffener, bring larger workload to the series of processes such as design, setting-out, blanking, assembling, welding, efficiency is lower.And concentrate because the pressurized position of cross-arm root during load action easily produces stress, make local compression easily cause mobile jib partial buckling, so cross-arm should not directly be connected with mobile jib again.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of safety is high, structure is simple, stress distribution is reasonable, and easy for installation, effectively can improve the Novel power transmission power line steel tuble pole of installation effectiveness.
For solving the problems of the technologies described above, the technical solution of the utility model is: Novel power transmission power line steel tuble pole, comprise steel pipe pole mobile jib, the external surface of described steel pipe pole mobile jib is provided with at least one perforation group, and described perforation group is included in the first perforation and second that described steel pipe pole mobile jib external surface is oppositely arranged and bores a hole; Also comprise and described perforation group cross-arm connecting plate one to one, one end of described cross-arm connecting plate penetrates steel pipe pole mobile jib from described first and then passes described steel pipe pole mobile jib from described second, and described cross-arm connecting plate is welded to connect at described steel pipe pole mobile jib.
As preferred technical scheme, described first perforation and described second perforation are bar hole, and described first perforation and described second perforation are longitudinally arranged at the external surface of described steel pipe pole mobile jib.
As preferred technical scheme, the external surface of described steel pipe pole mobile jib is provided with two described perforation groups.
Owing to have employed technique scheme, one end of described cross-arm connecting plate penetrates steel pipe pole mobile jib from described first and then passes described steel pipe pole mobile jib from described second, and described cross-arm connecting plate is welded to connect at described steel pipe pole mobile jib.Described first perforation and described second perforation are bar hole, and described first perforation and described second perforation are longitudinally arranged at the external surface of described steel pipe pole mobile jib.Such structure is adopted to greatly reduce structural complexity, and run through steel pipe pole mobile jib because of cross-arm connecting plate instead of be directly welded to steel pipe pole mobile jib, the stress that such structure can offset part cross-arm root is concentrated, avoid stressedly concentrating on situation steel pipe pole mobile jib causing partial buckling, structure is simple, stress distribution is reasonable, and effectively can improve installation effectiveness, reduce costs.

Detailed description of the invention
As depicted in figs. 1 and 2, Novel power transmission power line steel tuble pole, comprise steel pipe pole mobile jib 1, the external surface of described steel pipe pole mobile jib 1 is provided with two perforation groups, described steel pipe pole mobile jib also can be provided with the described perforation group of a described perforation group or other numbers plural, described perforation group is included in the first perforation 2 and the second perforation 3 that described steel pipe pole mobile jib external surface is oppositely arranged; Also comprise and described perforation group cross-arm connecting plate 4 one to one, the two ends of cross-arm connecting plate 4 are provided with the installing hole 5 installing cross-arm, one end of described cross-arm connecting plate 4 penetrates steel pipe pole mobile jib from described first perforation 2 and then passes described steel pipe pole mobile jib 1 from described second perforation 3, and described cross-arm connecting plate 4 is welded to connect at described steel pipe pole mobile jib 1.
As shown in Figure 3 and Figure 4, described first perforation 2 and described second perforation 3 are bar hole, and described first perforation 2 and described second perforation 3 are longitudinally arranged at the external surface of described steel pipe pole mobile jib 1.
The external surface of described steel pipe pole mobile jib 1 is provided with two described perforation groups.
One end of described cross-arm connecting plate 4 penetrates steel pipe pole mobile jib 1 from described first perforation 2 and then passes described steel pipe pole mobile jib 1 from described second perforation 3, and described cross-arm connecting plate 4 is welded to connect at described steel pipe pole mobile jib 1.Described first perforation 2 and described second perforation 3 are bar hole, and described first perforation 2 and described second perforation 3 are longitudinally arranged at the external surface of described steel pipe pole mobile jib 1.Such structure is adopted to greatly reduce structural complexity, and run through steel pipe pole mobile jib 1 because of cross-arm connecting plate 4 instead of be directly welded to steel pipe pole mobile jib 1, the stress that such structure can offset part cross-arm root is concentrated, avoid stressedly concentrating on situation steel pipe pole mobile jib 1 causing partial buckling, structure is simple, stress distribution is reasonable, and effectively can improve installation effectiveness, reduce costs.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
