The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
Such as Fig. 1, Fig. 2, Fig. 3, a kind of hoop bracket for video monitoring system is installed on the steel tube tower in electric transmission line shown in Figure 4, comprisemounting base 1,secondary hoop bracket 2,main hoop bracket 3, mountingbase locking hole 4, mountingbase locking nut 5, hoopbracket lock bolt 6, hoopbracket locking nut 7, reinforcingrib 8, mainhoop bracket ear 9, main hoop bracket locking hole 10, secondary hoopbracket locking hole 11, secondaryhoop bracket ear 12.
Be used for the axis side views such as support of the main hoop bracket of installation video monitoring system on the steel tube tower in electric transmission line as shown in Figure 3.Main hoop bracket 3 comprises the arc anchor ear sheet of two-layer parallel arrangement, there is mainhoop bracket ear 9 at the two ends of every one deck arc anchor ear sheet, be welded with reinforcingrib 8 between mainhoop bracket ear 9 and the arc anchor ear sheet, mainhoop bracket ear 9 centers are drilled with main hoop bracket locking hole 10.Main hoop bracket and secondary hoop bracket fix and are connected by insert hoopbracket locking nut 7 between main hoop bracket locking hole 10, secondary hoop bracket locking hole 11.Mounting base 1 comprises two opening support frames, outside framework.The support frame of two openings is identical right angle U-shaped framework.Right angle U-shaped framework comprises the different parallel edges of two length and perpendicular to the right-angle side of parallel edges.The parallel edges of right angle U-shaped framework is welded on arc anchor ear sheet lateral wall center in the direction perpendicular to arc anchor ear sheet string, and the parallel edges of two right angle U-shaped frameworks is 90 degree angles simultaneously.Outside framework fits tightly and surrounds two right angle U-shaped frameworks, contacts and is welded on the main hoop bracket with 4 of each layer arc anchor ear sheets up and down.Be drilled with mountingbase locking hole 4 on the vertical edges of shell and the first right angle U-shaped framework, be drilled with mountingbase locking hole 4 on the vertical edges of shell and the second right angle U-shaped framework, be welded with mountingbase locking nut 5 in the mountingbase locking hole 4, be convenient to plug-in video monitoring equipment.The height ofmounting base 1 is determined according to the number of anchor ear sheet.
As shown in Figure 4,secondary hoop bracket 2 comprises the arc anchor ear sheet of two-layer parallel arrangement, there is secondaryhoop bracket ear 12 at the two ends of every one deck arc anchor ear sheet, be welded with reinforcingrib 8 between mainhoop bracket ear 12 and the arc anchor ear sheet, mainhoop bracket ear 12 centers are drilled with main hoop bracket locking hole 11.The arc anchor ear sheet of respective layer is fixedly connected with by the hoop bracket locking nut in every one deck arc anchor ear sheet in themain hoop bracket 3 and thesecondary hoop bracket 2.
As seen, mounting base has used triangle to stablize stressed principle, in the mounting base locking hole of mounting base both sides, be welded and fixed the mounting base locking nut, reduced at the aerial movable part of height, prevent high-altitude part accidental falling, it is simpler, faster, safer to make lifting high-altitude article reduce as much as possible to reach the high-altitude installation exercise.Main hoop bracket has adopted up and down multilayer anchor ear design, makes very firm of integral support load-bearing, and has increased the contact area between hoop bracket and the steel tube tower, can make hoop bracket to the sufficient Uniform Dispersion of the power of steel tube tower contact portion.Secondary hoop bracket adopts the structure structure identical with main hoop bracket to be fixedly connected with convenient disassembly by nut with main hoop bracket.
