Embodiment
below in conjunction with embodiment, the present invention is described in further details:
the present invention be a kind of low-voltage power line construction aid, be mainly used in low-voltage circuit run into small angle tower situation under auxiliary construction.Aid structure of the present invention is simple, facilitates installing/dismounting, reduces construction number, increases work efficiency.
as shown in Figures 1 to 3, the present invention includes pulley 3, the pulley fixing device be made up of pulley spindle 31, fixing chuck plate 8, U-shaped card 1 and J-shaped bolt 4 etc., and take off wheel mechanism for the wire that wire disengaging pulley is fixed on the insulator.The outer circumference surface of pulley 3 of the present invention offers groove, for limiting travel path during wire construction, making wire not depart from pulley 3 when constructing, can not ride on cross-arm; Described pulley 3 is connected with pulley spindle 31 by bearing, and pulley spindle 31 fixing (or relatively fixing) is on fixing chuck plate 8, and fixing chuck plate 8 is fixed on cross-arm by fixed mechanism; U-shaped card 1 and J-shaped bolt 4 form the fixed mechanism of fixing chuck plate 8, and wherein U-shaped card 1 adopts with fixing chuck plate 8 and is flexibly connected, and is connected to one end of fixing chuck plate 6, and J-shaped bolt 4 is through in the fixing hole 12 on U-shaped card 1; Described fixing chuck plate 8 is arranged L shape draw-in groove 7, the notch of L shape draw-in groove 7 is positioned at the mid portion of fixing chuck plate, the direction of the groove tail bearing of trend trend pulley 3 of L shape draw-in groove 7, the setting of L shape draw-in groove 7 is to be fixed on easily on cross-arm by fixing chuck plate 8, during use, the L shape draw-in groove 7 of fixing chuck plate 8 is blocked the fixed lever of insulator, owing to being subject to the extruding force of wire to pulley, the fixed lever of insulator can not be thrown off, see Fig. 4 from L shape draw-in groove 7.
after completing to make wire construction, easily take off from pulley, and further colligation on the insulator, the present invention devises wire and takes off wheel mechanism, this wire takes off wheel mechanism and realizes primarily of hydraulic jack 2, the cylinder body of described hydraulic jack 2 is fixed on fixing chuck plate 8, connected by an oil pipe 6 between the hydraulic oil import and export of hydraulic jack 2, in the middle of oil pipe 6, valve 5 is set, cylinder bar 21 end of hydraulic jack 2 connects pulley spindle 31, pulley spindle 31 is inverted T-shaped axle, T-shaped section is fixed in the chute on fixing chuck plate 8, straight section is through the axis hole of cylinder bar 21 end and fixed block 3.Moved back and forth along chute by the extension and contraction control pulley spindle 31 of hydraulic jack cylinder bar 21, thus band movable pulley moves back and forth, when hydraulic jack cylinder bar shrinks, pulley moves and the wire in pulley grooves is blocked by insulator, now, just can colligation wire, dismounting pulley.Hydraulic jack 2 hydraulic oil is connected by an oil pipe 6 between importing and exporting, and do not arrange external drive, oil circuit is completely closed, arrange valve 5 in the middle of oil pipe, by the circulation of valve 5 hydraulic control oil, thus hydraulic control oil cylinder bar is reciprocal, valve, by manually having come, during adjustment, is opened in the position of cylinder bar in hydraulic jack, hydraulic oil circulates, the position of artificial adjustment hydraulic jack cylinder bar, after adjusting, valve-off, hydraulic oil can not circulate, and cylinder bar position is fixed.
fixing chuck plate 8 of the present invention is fixed on cross-arm when using, make pulley relatively fixing, because pulley spindle is arranged in the chute of fixing chuck plate, conveniently installation and maintenance, described fixing chuck plate 8 is made up of two parts, a part is base plate 81, a part is top board 82, top board 82 is fixed on base plate 81, base plate 81 is arranged strip groove, top board 82 also arranges strip groove, position is put corresponding with the strip slot on base plate 81, geomery matches, and arranges elongate holes at the center of strip groove simultaneously; During assembling, strip groove one on top board 82 faces down, make base plate relative with the strip groove on top board, form chute, in chute, pulley spindle 31 is installed, the T-shaped section of pulley spindle 31 coordinates with chute, straight section stretches out from elongate holes, during installation, is first passed from the elongate holes of top board by pulley spindle, assemble top board and base plate again, top board and base plate adopt bolt to fix.
when fixing chuck plate 8 of the present invention is fixed on cross-arm, first the L shape draw-in groove card 7 of self is passed through on the fixed lever of insulator, simultaneously, adopt U-shaped card 1 and J-shaped bolt 4 spacing fixing, U-shaped card 1 is fixing critical component, described U-shaped card 1 is asymmetric board-like U-shaped card, comprise two straight plate section and arc sections of one, arc section is positioned between two straight plate sections, and connect two straight plate sections, two straight plate sections be arranged in parallel, but length is different, longer straight plate section arranges strip hole 11, and near end, fixing hole 12 is being set, see Fig. 3.Strip hole 11 is for being slidably connected with fixing chuck plate, by connector, U-shaped card is slidably connected on fixing chuck plate, during use, U-shaped card can be made to slide within the scope of strip hole along connector, thus make the openend of U-shaped card can be positioned at left side or the right side of fixing chuck plate, conveniently J-shaped bolt is caught on cross-arm, carry out fastening, fixing chuck plate and cross-arm are connected firmly.The J-shaped section of J-shaped bolt 4 catches on cross-arm, and thread segment (straight section), through the fixing hole 12 of U-shaped card 1, is undertaken fastening by bolt, is limited in the U groove of U-shaped card the end of fixing chuck plate, and makes it be pressed on cross-arm.Effect is see Fig. 4.
