Technical field
The utility model relates to the electric power transportation art, especially relates to a kind of electric armour clamp, is specifically related to a kind of carbon fiber photoelectricity compound wire anchor clamps.
Background technology
Carbon fiber photoelectricity compound wire anchor clamps are the gold utensils a kind of commonly used that are used for fixing cord on sky frame power circuit and the electric substation's shaft tower in the electric power system; It is connected lead with insulator string; Insulator string is connected with iron tower again; In order to carry the pulling force of lead, reduce the sag of lead, crucial effect is played in the safe operation of electric power system.
Fig. 1 is the structural representation of existing carbon fiber photoelectricity compound wire anchor clamps, and is as shown in Figure 1, and these anchor clamps comprise the outer tube 16 of a pipe shape; The outer circumference surface of outer tube 16 right parts is provided with drainage plate 19, is provided with the clamping device of the carbon fiber complex core that is used for clamping wire in the inner chamber of outer tube 16, and clamping device is made up of locking sleeve 13 and locking inner core 14 suits; The outer surface of locking inner core 14 is round table-like and is provided with axially extending bore; Locking sleeve 13 is provided with and locks the suitable circular cone shape through hole of outer surface of inner core 14 vertically, and the left end right-to-left of steel anchor 15 inserts in the outer tube 16 and with locking sleeve 13 and is threaded, and the right-hand member of lead 12 inserts from the left end of outer tube 16; Carbon fiber complex core 18 1 ends insert in the lead 12; The other end is inserted in the axially extending bore on the locking inner core 14, and card presses outer tube 16 to make lead 12 clamp carbon fiber complex core 18, and promotes locking inner core 14 to the right through rotating steel anchor 15; Make locking inner core 14 produce radial deformation chucking carbon fiber complex core 18; During use, locking inner core 14 slides to the right under the pulling of lead 12, so the locking inner core 14 further radial deformations that produce clamp carbon fiber complex core 18 under the extruding of locking sleeve 13; Because locking sleeve 13 adopts taper seat to cooperate with locking inner core 14, therefore draws tighter and tighter.
There is following shortcoming in the carbon fiber photoelectricity compound wire anchor clamps of said structure:
(1), the thermal diffusivity of these anchor clamps is relatively poor.
(2), because drainage plate 19 is arranged on the right part of outer sleeve 16, the distance between lead 12 and the drainage plate 19 is longer, so the resistance of anchor clamps is bigger.
(3), locking sleeve 13 and locking inner core 14 are when clamping carbon fiber complex core 18; Under powerful external force pulling force, very easily make locking inner core 14 skew and block; Thereby make carbon fiber complex core 18 inhomogeneous at radial force; Very easily make it produce damage, even fracture, thereby reduced the axial carrying capacity of carbon fiber complex core 18.
(4), locking inner core 14 deformabilities are little, clamping force is little.
Simultaneously, existing anchor clamps can not be drawn the optical fiber in the photoelectricity compound wire, can't realize that light, electricity separate.In addition, existing anchor clamps receive wind-force easily and swing, and also receive clammy weather to form icing easily, and then cause transmission line galloping.
