Abstract
The utility model relates to a copper aluminium transition hanging string wire clamp. Circular arc shaped copper aluminium composite gaskets the shape of each of which is basically dovetailed with the shape of each of semicircular arc faces are fixed on the semicircular arc faces which are arranged at the inner side of a compression joint clamping plate and the inner side of a thread clamping plate. The outer circular arc faces of the circular arc shaped copper aluminium composite gaskets, which are made from copper materials, closely cling to the semicircular arc faces of the inner sides of the clamping plates, and the radius of each of inner circular arc faces which are made from aluminium materials is basically consistent with the radius of a catenary. The utility model can solve the electro-corrosion problem of a diversion hanging string through the transition of the copper aluminium composite gaskets under the condition that the volume of the main body of the wire clamp is not increased, and the intensity of the main body of the wire clamp is ensured, wherein, the electro-corrosion problem of the diversion hanging string occurs when a contact wire and a catenary are made from different materials. The utility model also has the advantages of strong versatility, favorable performance, low cost, convenient operation, and safety.
Description
The utility model relates to a kind of copper-aluminium transition hanger ear.
Existing hanger ear is generally made by a kind of material, and with folded clue is similar material, when contact wire and catenary material not simultaneously, with the material of its contact wire hanger ear that matches and catenary hanger ear also with different, if the hanger ear of two kinds of unlike materials is mechanically connected into integral body by the dropper line, as the water conservancy diversion dropper, then between the unlike material electrocorrosion problem will appear.
The purpose of this utility model is to design a kind of copper-aluminium transition hanger ear, when contact wire and catenary material not simultaneously, adopt the composite metal transient mode to make the catenary hanger ear identical with dropper wire rod matter with the material of dropper wire joint part, and it is identical with the material of catenary connecting bridge with the catenary material, it is reliable to guarantee that not only the mechanical electric performance connects, and can prevent that the electrocorrosion problem from producing.
Design plan of the present utility model: a kind of copper-aluminium transition hanger ear, comprise crimping clamping plate (1), screw thread clamping plate (2), bolt (3), nut (4) and packing ring (5), be fixed with the circular arc copper aluminium composite pad (6) that shape and semicircle cambered surface are coincide substantially on the semicircle cambered surface of crimping clamping plate (1) and screw thread clamping plate (2) inboard, the exterior arc surface (7) of circular arc copper aluminium composite pad (6) is a copper material, and must be closely connected with the semicircle cambered surface of crimping clamping plate (1) and screw thread clamping plate (2) inboard, inner arc surface (8) is an aluminium material, and its radius and catenary radius basically identical.Circular arc copper aluminium composite pad (6) is made by copper-aluminum composite board.
The utility model compared with prior art, the one, be the atom combination between the copper aluminum composite material, mature production technology is stable, can prevent electrocorrosion fully; The 2nd, copper aluminium composite pad thickness can be very thin, can utilize the existing hanger ear semi arch radius surface that it is inboard a little more greatly, can be fixed on the semicircle cambered surface copper aluminium composite pad is closely connected, needn't increase the wire clip body volume, still can guarantee its intensity; The 3rd, highly versatile, performance is good, and cost is low, and is easy to use, safe and reliable.
Fig. 1 is this practical structural representation;
Fig. 2 is the left view of Fig. 1
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of copper-aluminium transition hanger ear, comprise crimping clamping plate (1), screw thread clamping plate (2), bolt (3), nut (4) and packing ring (5), be fixed with the circular arc copper aluminium composite pad (6) that shape and semicircle cambered surface are coincide substantially on the semicircle cambered surface of crimping clamping plate (1) and screw thread clamping plate (2) inboard, the exterior arc surface (7) of circular arc copper aluminium composite pad (6) is a copper material, and must be closely connected with the semicircle cambered surface of crimping clamping plate (1) and screw thread clamping plate (2) inboard, inner arc surface (8) is an aluminium material, and its radius and catenary radius basically identical.Circular arc copper aluminium composite pad (6) is made by copper-aluminum composite board, and crimping clamping plate (1) and screw thread clamping plate (2) are made by copper alloy.Using method: when contact wire, dropper line are copper material, when catenary is aluminium material, the contact wire hanger ear is a copper material, after the catenary hanger ear is selected the utility model for use, at first the dropper line pressure is connected in the crimping handle of crimping clamping plate (1), by bolt (3), nut (4) and packing ring (5) the utility model is clamped on the catenary then, make it partly to be copper material with the dropper wire joint, and with the catenary connecting bridge be aluminium material, can fundamentally solve the electrocorrosion problem, be specially adapted to the flow-guiding type dropper.
Claims (2)
1, a kind of copper-aluminium transition hanger ear, comprise crimping clamping plate (1), screw thread clamping plate (2), bolt (3), nut (4) and packing ring (5), it is characterized in that: be fixed with the circular arc copper aluminium composite pad (6) that shape and semicircle cambered surface are coincide substantially on the semicircle cambered surface of crimping clamping plate (1) and screw thread clamping plate (2) inboard, the exterior arc surface (7) of circular arc copper aluminium composite pad (6) is a copper material, and must be closely connected with the semicircle cambered surface of crimping clamping plate (1) and screw thread clamping plate (2) inboard, inner arc surface (8) is an aluminium material, and its radius and catenary radius basically identical.
2, copper-aluminium transition hanger ear according to claim 1 is characterized in that: circular arc copper aluminium composite pad (6) is made by copper-aluminum composite board.
