Description

新型输电线路钢管杆New steel pipe poles for transmission lines

技术领域technical field

背景技术Background technique

输电钢管杆横担常用的连接方式有连板加劲和法兰连接两种。连板加劲采用两块钢板配4~8块加劲板焊接至主杆,法兰连接采用配对法兰和一周若干加劲板焊接至主管,两者均需较多数量加劲板,给设计、放样、下料、组装、焊接等一系列工序带来较大的工作量,效率较低。而且因荷载作用时横担根部的受压部位容易产生应力集中,使局部受压易导致主杆局部压曲,所以横担又不宜直接与主杆连接。There are two commonly used connection methods for transmission steel pipe pole cross arms: connecting plate stiffening and flange connection. Two steel plates and 4 to 8 stiffening plates are used to weld the connecting plate to the main rod. The flange connection adopts matching flanges and several stiffening plates welded to the main pipe. Both require a large number of stiffening plates for design, lofting, A series of processes such as blanking, assembly, and welding bring a large workload and low efficiency. Moreover, stress concentration is likely to occur at the compressed part of the root of the cross-arm when the load acts, and local compression can easily lead to local buckling of the main rod, so the cross-arm should not be directly connected to the main rod.

The first through-hole and the second through-hole are strip-shaped holes, and the first through-hole and the second through-hole are arranged longitudinally on the outer surface of the main rod of the steel pipe rod. The use of such a structure greatly reduces the structural complexity, and because the cross-arm connecting plate runs through the main rod of the steel pipe rod instead of being directly welded to the main rod of the steel pipe rod, this structure can offset the stress concentration at the root of some cross-arms and avoid the concentration of force on the In the case of local buckling caused by the main rod of the steel pipe rod, the structure is simple, the stress distribution is reasonable, and the installation efficiency can be effectively improved and the cost can be reduced.
