Abstract
The utility model belongs to a suspension clamp on an overhead transmission line, which is provided with a bracket with a concave curved groove and a pressing plate with a raised concave curved groove, wherein, the bracket and the pressing plate are provided with four couples of symmetrical screw holes which can fasten a conducting wire for wrapping preformed armor rods between crankshafts of the bracket and the pressing plate, and both sides of the bracket are respectively provided with a buckle which is connected with a hanging plate. The bracket, the pressing plate, the hanging plate, the preformed armor rods and bolts of the utility model are all made of aluminum alloy material, and the utility model has the characteristics of no magnetic hysteresis loss, low energy consumption, reasonable structure, small moment inertia, convenient operation, easy producing, etc.
Description
The utility model belongs to a kind of suspension clamp that is used on the overhead transmission line.
Disclosed a kind of suspension clamp among prior art such as the GB2313-85, wire clamp hull of being made by malleable cast iron or steel plate and pressing plate and U-shaped screw are formed.It utilizes two U-shaped screw clamping platens to make lead fixed in the hull of wire clamp, and hull is hung by the link plate that two block plates are stamped to form, and link plate is installed on the hanging scroll of hull both sides, and is fastening by split pin.There is following weak point in this wire clamp: 1. big, the Heavy Weight of volume; 2. being connected of wire clamp and link plate adopts bearing pin and split pin fastening, and overhead transmission line is in service both at home and abroad, and tens of accidents that cause packing ring rotation keeper fourth because of conductor vibration have taken place; 3. make wire clamp by ferrimagnet, magnetic hysteresis loss is serious, and power consumption is big.
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of rational in infrastructure, dependable performance, no magnetic hysteresis loss are provided, the pre-twisted fastener type suspension clamp of being made by aluminum alloy materials.
The utility model is achieved by the following technical solution: have with the carriage of recessed crank slot and the pressing plate of the recessed crank slot of a band protrusion, the screw that four pairs of symmetries are arranged on carriage and the pressing plate, be fastened between the bent axle of carriage and pressing plate by the lead of bolt the looping preformed armor rods, the carriage both sides respectively have a buckle to be connected with link plate, each buckle is made up of a cylinder and a kidney piece, two right-angle sides and the cylinder of kidney piece are tangent, two bent limits of kidney piece have with a certain distance from the fillet of cylinder and kidney piece, and the carriage bottom is smooth comprehensive arching face.
The utility model compared with prior art has carriage, pressing plate, link plate, preformed armor rods and bolt by the aluminum alloy materials manufacturing, no magnetic hysteresis loss, and energy consumption is low, and is rational in infrastructure, and moment of inertia is little, and is easy to use, makes characteristics such as simple.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the structural representation of carriage 1.
Fig. 4 is the structural representation of pressing plate 5.
Below in conjunction with accompanying drawing the utility model is described in detail.By the suspension clamp that carriage 1, pressing plate 5, link plate 8 are formed, in the middle of the carriage 1 a recessed crank slot 2 is arranged, the exit of recessed crank slot 2 is half bell mouth shape.Respectively there is a buckle carriage 1 both sides, each buckle is made up of a cylinder 3 and a kidney piece 4, two right-angle sides and the cylinder 3 of kidney piece 4 are tangent, and two bent limits of kidney piece 4 have with a certain distance from the fillet of cylinder 3 and kidney piece 4, and carriage 1 bottom is smooth comprehensive arching face.
The one recessed crank slot 6 that protrudes is arranged in the middle of pressing plate 5 belows, and more greatly, the recessed crank slot 6 of pressing plate 5 is more shallow and narrow than the recessed crank slot 2 of carriage 1 than the radius of curvature of the recessed crank slot 2 of carriage 1 for the radius of curvature of recessed crank slot 6.
The plane geometric shape that contacts of carriage 1 and pressing plate 5 is consistent, and the screw 7 of four pairs of symmetries is arranged, and by bolt lead (preformed armor rods that contains looping) is fastened between carriage 1 and the pressing plate 5.Preformed armor rods is shape in the shape of a spiral, and the internal diameter of shaping is littler than wire diameter, tightly is entangled in wire external layer, in the recessed crank slot of the carriage 1 of packing into.Preformed armor rods can with rubber-like high-strength aluminum alloy silk in accordance with regulations radical be one group and be prefabricated into helical form.But nationality helps elastic properties of materials to be pressed on the lead, does not produce slippage.
Link plate 8 is that one pair of cross section is oblateness, and both ends are the circular arc limit, and an end band circular port 9, the folding shape plate of other end band mounting hole 10.The angle of oscillation that link plate 8 and carriage are 1 can reach 1 to 45 °.
Claims (6)
1. the suspension clamp on the overhead transmission line, it is characterized in that having with the carriage of recessed crank slot and the pressing plate of the recessed crank slot of a band protrusion, the screw that four pairs of symmetries are arranged on carriage and the pressing plate, be fastened between the bent axle of carriage and pressing plate by the lead of bolt the looping preformed armor rods, the carriage both sides respectively have a buckle to be connected with link plate, each buckle is made up of a cylinder and a kidney piece, two right-angle sides and the cylinder of kidney piece are tangent, two bent limits of kidney piece have with a certain distance from the fillet of cylinder and kidney piece, and the carriage bottom is smooth comprehensive arching face.
2. suspension clamp according to claim 1, more greatly, the recessed crank slot of pressing plate is more shallow and narrow than the recessed crank slot of carriage than the radius of curvature of the recessed crank slot of carriage for the radius of curvature that it is characterized in that the recessed crank slot of pressing plate.
