Summary of the invention
Technical problem to be solved in the utility model is: a kind of electric force pole tower lead and the shared cross-arm device of ground wire of reasonable in design are provided, can reduce the shaft tower height, alleviate cross-arm weight, solved the ground wire cross-arm Layout Problem of the shaft tower of restriction tower height.
For solving the problems of the technologies described above, the technical solution of the utility model is: the shared cross-arm device of electric force pole tower lead and ground wire, comprise the lead cross-arm of fixedlying connected with the tower bar, be provided with the lead suspension arrangement at described lead cross-arm away from an end of tower bar, be fixedly connected with the ground wire cross-arm that upwarps at described lead cross-arm away from the end of tower bar one end, be provided with the ground wire suspension arrangement on the top of described ground wire cross-arm.
As a kind of optimized technical scheme, it is polygonal Taper Pipe that described lead cross-arm and described ground wire cross-arm are the cross section.
As a kind of optimized technical scheme, described lead cross-arm and described ground wire cross-arm are the cross section and are circular Taper Pipe.
As a kind of optimized technical scheme, described lead suspension arrangement comprises the lead thread gripping-board that is fixedly connected on the described lead cross-arm outer wall, and described lead thread gripping-board is provided with three lead hanging wire holes, and described three lead hanging wire holes are triangularly arranged.
Described ground wire suspension arrangement comprises fixedlys connected with the top port of described ground wire cross-arm and with the ground wire thread gripping-board of port closed, described ground wire thread gripping-board is provided with a ground wire hanging wire hole.
After having adopted technique scheme, the beneficial effects of the utility model are: because lead of the present utility model and the shared cross-arm device of ground wire, be fixedly connected with the ground wire cross-arm that upwarps at the lead cross-arm away from the end of tower bar one end, be provided with the ground wire suspension arrangement on the top of ground wire cross-arm, therefore the utility model connects as one lead cross-arm and ground wire cross-arm, during the assembling shaft tower, a ground wire cross-arm and a layer conductor cross-arm only account for the space of one deck cross-arm, therefore, the utility model can effectively reduce the height of shaft tower, and alleviated the weight of cross-arm,, solved the Layout Problem of its ground wire cross-arm for the special shaft tower of restriction tower height.
