As a kind of prioritization scheme, the upper and lower of support frame as described above is respectively arranged with link, and said link and bracing frame removably connect.
A kind of concrete prioritization scheme, the link on support frame as described above top is provided with a plurality of through holes.
A kind of concrete prioritization scheme, the link of support frame as described above bottom is provided with pedal, and said pedal and link removably connect.
As a kind of prioritization scheme, said link is a connecting rod, and the two ends of one of them connecting rod bend to the same side.
As a kind of prioritization scheme, support frame as described above is connected with fixed lever.
A kind of concrete prioritization scheme, the quantity of said fixed lever are two.
As a kind of prioritization scheme, said cross-arm is provided with bearing, and said bearing is provided with arc groove, and the top of said bearing is provided with fixed cap.
As a kind of prioritization scheme, the quantity of said support bar is three.
A kind of concrete prioritization scheme, the support bar in the middle of being positioned at is provided with three cross-arms, is positioned at wherein that the support bar of an end is provided with a cross-arm, and the support bar that is positioned at the other end is provided with two cross-arms.
The utility model is taked above technical scheme; Have the following advantages: because the end of each support bar is positioned on the same circumference; Said support bar is provided with the cross-arm of placing cable, so after bracing frame is installed, have the gap between support bar and the pipeline; Earth connection is arranged between the gap, and earth connection is easy for installation; The end of each support bar of bracing frame is positioned on the inwall of pipeline; Bracing frame is not fixedly connected with pipeline, and cable bearer is easy for installation, under cable bearer and pipeline expansion and contraction condition of different; Can not damage pipeline and cable bearer, prolong the useful life of pipeline and cable bearer greatly.
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
