Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present invention includes the earth connection fixture and insulation adjusting rod that removably connect, described earth connection fixture comprises standing part and movable part, standing part comprises train wheel bridge 1 and bus conductive plate 2, train wheel bridge 1 is connected with bus conductive plate 2 is vertical, the lower surface of train wheel bridge 1 is provided with the wire casing 20 to fovea superior, and wire casing 20, for clamping bus, prevents bus landing.The end of bus conductive plate 2 is provided with ground wire gim peg 11, and bus conductive plate 2 offers through hole 8 by left side to right side.Movable part comprises lower clamping piece 5, screw rod 6, polygon-shaped seat 7 and locating rack, locating rack comprises vertical connecting plate 3 and cross connecting plate 4, the right-hand member of cross connecting plate 4 vertically connects the end of vertical connecting plate 3, the right side wall of vertical connecting plate 3 connects two pilot pins 9, and pilot pin 9 is also fixed by nut 10 through through hole 8; Cross connecting plate 4 offers screw 19 from top to bottom, and screw rod 6 is threaded with screw 19, and the top of screw rod 6 connects lower clamping piece 5, and the end of screw rod 6 connects polygon-shaped seat 7.Described insulation adjusting rod comprises top connecting rod and bottom extension rod, top connecting rod comprises the first insulating bar 14, the top of the first insulating bar 14 connects polygon sleeve 13, shape and the polygon-shaped seat 7 of polygon sleeve 13 match, polygon sleeve 13 and polygon-shaped seat 7 removably connect, as clamping.First insulating bar 14 end is provided with top connector 16; Top connector 16 is hollow cylindrical drum, and hollow cylindrical inner horizontal is provided with a gag lever post 17, and the top of hollow cylindrical tube is set in the first insulating bar 14 end.The top that bottom extension rod comprises the second insulating bar 15, second insulating bar 15 matches with the connector of the first insulating bar 14 end and is connected.The top end face of the second insulating bar 15 offers draw-in groove 18, and gag lever post 17 is located in draw-in groove 18, and the overall diameter of the second insulating bar 15 is less than the interior diameter of top connector 16.Bottom extension rod end is provided with the connector identical with the top connector 16 of the first insulating bar 14 end.Described bottom extension rod is provided with many.
Operation principle of the present invention is illustrated below in conjunction with accompanying drawing:
As shown in Figure 1, first, staff estimates the thickness of aluminium row or the fineness of bus, manually adjust location first, first the supporting nut 10 of pilot pin 9 is loosened, pilot pin 9 is relaxed, and thickness visually or thickness roughly locate the upper-lower position of locating rack, then tightening nuts 10.Because vertical connecting plate 3 right side wall of locating rack adopts planar structure, the left side wall of bus conductive plate 2 also adopts planar structure, vertical connecting plate 3 can be made to fit together closely with bus conductive plate 2, more firmly fix locating rack.Then, earth connection is fixed on earth connection fixture by ground wire gim peg 11, plays the effect of conduction, by the conduct current the earth revealed in work, avoid staff to get an electric shock, life threatening.Secondly, then be set on polygon-shaped seat 7 by the polygon sleeve 13 on connecting rod top, top, now, staff can elevate earth connection fixture like a cork, is located at by earth connection fixture on the equipment of needs maintenance.Now, earth connection fixture does not firmly clamp repair apparatus, so, need again to regulate subtly.Before being elevated by earth connection fixture, staff needs to estimate the height residing for repair apparatus, connects bottom extension rod according to altitudes.As shown in Figure 4, for the enlarged drawing in Fig. 3 A portion, top connecting rod and bottom extension rod are linked together by top connector 16, the inner horizontal of top connector 16 is provided with a gag lever post 17, also " one " font cross bar is, this kind of structure is adopted to couple together quickly and easily, easy to operate.Gag lever post 17 can mate in the draw-in groove 18 being located at and the top barrel of the second insulating bar 15 is offered relatively, because insulation adjusting rod is held by staff to support whole weight, add gravitational effect, gag lever post 17 can not come off by draw-in groove 18 easily, ensures the validity used.After staff installs insulation adjusting rod, need to carry out accurate adjustment, because lower clamping piece 5 is moved up and down by the effect of screw rod 6, and screw rod 6 needs rely on the effect of insulation adjusting rod and rotate, so, now, staff manually rotates insulation adjusting rod, and screw rod 6 is rotated, lower clamping piece 5 finally can be made to move up and down, according to the situation of reality, upwards regulate or regulate downwards, until can repair apparatus be stepped up.
The present invention adopts top connector 16 to connect top connecting rod and bottom extension rod, mainly because insulation adjusting rod is in long-term use procedure, can be lossy, when operated by personnel is improper or parts frequency of utilization is high time, gag lever post 17 likely can be twisted into two parts, draw-in groove 18 can be out of shape, these all can affect the insulation Fast Installation of adjusting rod and easy to use, so, adopt the replacing that top connector 16 can carry out at any time.Meanwhile, in the work on the spot of reality, need to carry many eradication edge adjusting rods, in case one is damaged and affects normal service.
