Background technology
Being used for steel construction self-supporting steel tower that communications transmit antenna and feeder line install generally has two kinds of rectangle tower and three turrets, because rectangle steel structure self-supporting steel tower floor space is big, the steel consumption is big, cost is high, is therefore replaced by triangle self standing tower gradually.Triangle self standing tower has the advantage that floor space is little, simple in structure firmly, the steel consumption is few, cost is low.Needs for communication system feeder line ground connection, the existing communication triangle self standing tower is provided with earthing strip in tower body, and the earth point of installing hole as the communication system feeder line be set on earthing strip, this structure has the following disadvantages: the one, and the ground hole position on the earthing strip is difficult to determine, if boring at the construction field (site), then can destroy the coating on the earthing strip, earth point gets rusty easily and causes loose contact, influences the ground connection effect; The 2nd, the mechanical strength that installing hole has had a strong impact on earthing strip is set on earthing strip, when earthing strip is installed rupture easily in the installing hole place of earthing strip, the setting of installing hole simultaneously reduces the net sectional area of earthing strip significantly, causes the earthing strip through-current capability to descend, and has influenced passing through of earth-current; The 3rd, because earthing strip generally adopts band steel to make, and the earth terminal of feeder line is a steel structure, and chemical change takes place in air easily in both junctions, thereby causes contact resistance to increase, and influences the ground connection performance of whole feeder system.
The utility model content
The utility model is low for the mechanical strength that the earthing strip that solves present communication triangle self standing tower exists, a little less than the through-current capability, the problem of ground connection weak effect provides the feeder line earthing device of a kind of mechanical strength height, through-current capability is strong, ground connection is effective triangle self standing tower.
The utility model is to reach the concrete technical scheme that above-mentioned technical purpose adopts to be: the feeder line earthing device of triangle self standing tower comprises earthing strip, and the upper end of earthing strip is unsettled, and the lower end is connected with the earth mat of column foot, and earthing strip is provided with some ground connection copper bars.Appropriate location on earthing strip is provided with the ground connection copper bar, the junction of earthing strip and feeder line ground connection copper sleeve all is arranged on the ground connection copper bar, like this, can avoid on earthing strip, being provided with installing hole, net sectional area, the through-current capability of earthing strip are kept, and the mechanical strength of earthing strip also is guaranteed, simultaneously, contact well between copper bar and the ground connection copper sleeve, guaranteed the ground connection effect of feeder line.
As preferably, the ground connection copper bar is a bow-shaped structural, and arched two ends are steel construction, and mid portion is a steel structure, and arched two ends and earthing strip welding are fixing, and steel structure is provided with the plurality of fixed hole.The steel construction at arched two ends earthing strip easy and steel welds, middle steel structure can guarantee with feeder line ground connection copper sleeve between contact well, fixing hole is used for fixing feeder line ground connection copper sleeve, and bow-shaped structural itself helps being spirally connected between ground connection copper bar and the feeder line ground connection copper sleeve.
As preferably, be provided with climbing frame in the triangle self standing tower, the centre of climbing frame is a mobile jib, and the both sides of mobile jib are provided with and scrunch, and earthing strip is provided with on the climbing frame.Climbing frame is set is and be convenient to staff's iron tower up and down, help installing and safeguarding, earthing strip is arranged on the climbing frame, can make things convenient for installing and fixing of earthing strip, also be convenient to being connected and regular maintenance of feeder line ground connection copper sleeve and ground connection copper bar.
As preferably, earthing strip is a flat structure, and the mobile jib of climbing frame is a rhs-structure, and mobile jib is fixed on the carriage that is provided with on the horizontal iron of triangle self standing tower one side by anchor ear, and earthing strip is arranged between mobile jib and the carriage.Earthing strip is arranged between mobile jib and the carriage, then need not to be provided with separately the earthing strip installing mechanism, climbing frame is installed is only to need earthing strip is clipped between mobile jib and the carriage and get final product, after mobile jib was fixing, earthing strip was fixing thereupon, like this can simplified structure, the saving cost.Earthing strip also can be arranged on an end that scrunches away from mobile jib.
As preferably, the ground connection copper bar is two, is separately positioned on the earthing strip that is positioned at body of the tower top and bottom.For higher iron tower, the ground connection copper bar also can be separately positioned on the earthing strip of climbing frame top, middle part and bottom with three.
As preferably, feeder line is arranged on the climbing frame, and the earth terminal of feeder line is fixed on the ground connection copper bar.Feeder line is arranged on the climbing frame, and the one, make things convenient for setting up and safeguarding of feeder line, the 2nd, feeder line is nearer from earthing strip, makes things convenient for the ground connection of feeder line.
The beneficial effects of the utility model are: it has solved effectively, and the mechanical strength that the earthing strip of present communication triangle self standing tower exists is low, through-current capability weak, the problem of ground connection weak effect, the utility model is simple in structure, mechanical strength is high, through-current capability is strong, ground connection is effective, is worthy of popularization.
