Embodiment
First kind of embodiment of the utility model described below in conjunction with accompanying drawing 1-7.
The cable insulation support that is used for track traffic can be fixing with circular tunnel.The outer side surface of weight body 1 is the arc surface suitable with attachment face, is uniformly distributed with two overhangs 2 on the said weight body 1, and this support is one-body molded by the mold pressing of frpf SMC material.Weight body 1 is provided with and can it be mounted on circular attachment hole 4 and long strip attachment hole 5 on the tunnel, and circular attachment hole 4 is positioned at weight body 1 top, is designed with installation base 6 with the wall contact position; Long strip attachment hole 5 is positioned at the bottom of weight body 1, also is designed with installation base 6 with the wall contact position, is convenient to fix, and the design of long strip attachment hole 5 can be adjusted the mounting point of support.The exterior edge face of weight body 1 is arc surface or the straight wall suitable with attachment face, and said overhang 2 is shaped on two, is shaped on triangular groove 11 on the weight body 1 and makes the cross section of weight body 1 be " worker " font structure; (like Fig. 3); This kind structure Design not only can alleviate the weight of weight body 1, and elegant in appearance; Said overhang 2 is made up of weight-bearing surface 10 and the triangle stiffening rib 7 that is positioned at weight-bearing surface 10 belows; The bi-side symmetry of said triangle stiffening rib 7 has triangular groove 8 makes the cross section of overhang 2 be " worker " font structure, and inboard and through hole 3 both ends of the surface that said through hole 3 is positioned at triangular groove 8 have stiffening rib 13, makes this place's overhang cross section be two " worker " font structures; Can alleviate the impact of Piston Wind to support; And intensity is good, and weight-bearing surface 10 and its corresponding surface of overhang 2 all are shaped on boss 9, are convenient to binding, attached cable.The weight-bearing surface 10 and the horizontal plane of overhang 2 have upwarping of 2.5 degree, and overhang 2 is shaped on baffle plate 12 apart from weight body 1 than far-end, and cable is not easy to outer rolling, and this support wall thickness uniform Design is convenient to compression molding, is practiced thrift cost.
