Specific embodiment

Fig. 1 is the structural representation of suspension clamp；Fig. 2 is the left view of Fig. 1；Suspension clamp adopts 1 add-back rotating shaft 2 of hanger Mode is attached, and has pad 3 and split pin 4 at the two ends of gyroaxis 2.But it sometimes appear that the problem that split pin comes off, such as Add not in time, it may occur however that the accident that wire drops.Add, if the back side one that people can't see The split pin of side comes off, band point add operation it is extremely complex, waste time and energy.

Embodiment

Fig. 3 is the schematic diagram of this utility model suspension clamp for electric line dress pin device embodiment；Fig. 4 is the left view of Fig. 3； This utility model suspension clamp for electric line dress pin device, including the connection of mounting head 5, extension rod 6, sleeve 7, wheel disc 8, action bars Rod 9, pipe collar 10, pipe collar screw 11, mirror holder 12, eyeglass 13；There are pipe collar 10, pipe collar 10 on described action bars pitman 9 On have pipe collar screw 11, pipe collar 10 is connected with mirror holder 12 by pipe collar screw 11, has eyeglass 13 on mirror holder 12；It is characterized in that： Extension rod 6 is welded with described mounting head 5, extension rod 6 is connected through sleeve 7 with wheel disc 8, and wheel disc 8 can drive extension rod 6 Rotate in sleeve 7；Action bars pitman 9 is welded with sleeve 7；Fig. 5 is the sectional view of mounting head 5；Fig. 6 is the vertical view of Fig. 5 Figure；Fig. 7 is the left view of Fig. 5, and mounting head 5 includes pipe 14, piston 18, has symmetrical twice keyway 15 on 14 inwall of pipe, 14 front end keyway 15 of pipe and 16 insertion of little gap, 14 rear end keyway 15 of pipe are welded with 17 insertion of long gap and with extension rod 6； There is piston 18 in pipe 14, on piston 18, be connected with slide block 19, slide block 19 can slide in keyway 15, and 19 rear end of slide block has little convex Block 20, small lugs 20 are stretched out from long gap 17；There is adjustment screw 21 at 18 center of piston, for adjusting the movement travel of piston 18, Fig. 8 is the schematic diagram that piston 18 moves to rear end, and Fig. 9 is the top view of Fig. 8；Piston 18 moves to front end and is limited by small lugs 20 Can not deviate from.Catch 24 is welded with extension rod 6, for preventing the axial float in the sleeve 7 of extension rod 6.

During use, this utility model suspension clamp for electric line is filled into the action bars pitman 9 and insulating bar of pin device Eyeglass 13 is adjusted to appropriate angle by connection, on wheel disc 8 fixed insulation rope winds several circles；Adjustment adjustment screw 21 determines The stroke of piston 18；Stirring small lugs 20 makes piston 18 move to front end, and Figure 10 is SBR schematic diagram, in little gap 16 The opening termination of ring spring pin 22 is put into, the opening termination of ring spring pin 22 is prevented to be in by the slide block 19 on piston 18 opens Open state；In the case where safe distance is ensured, make extension rod 6 vertical with wire, look at eyeglass 13 and allow 5 center of mounting head to be aligned Gyroaxis 2 comes off one end propulsion of split pin, and piston 18 pushes up rear end by gyroaxis 2, and Figure 11 is that piston 18 is pushed up by gyroaxis 2 The schematic diagram of rear end, now the opening termination of ring spring pin 22 be seized gyroaxis 2, pull insulating cord, wheel disc 8 is by extending Bar 6 drives mounting head 5 to rotate, and mounting head 5 drives ring spring pin 22 to rotate, until the opening termination of ring spring pin 22 falls into Till in the pin-and-hole 23 of gyroaxis 2, this utility model suspension clamp for electric line dress pin device, installation are extracted out.Figure 12 is peace The schematic diagram for installing.

During installation, if the stroke of the motion of piston 18 is too short, the opening termination of ring spring pin 22 is not arrived pin-and-hole 23 Position, do not install；If the stroke of the motion of piston 18 is long, the opening termination of ring spring pin 22 has just exceeded pin-and-hole 23 Position, do not install yet；Therefore, the stroke that will be moved according to the distance of pin-and-hole 23 to 2 termination of gyroaxis adjustment piston 18, It is exactly the stroke of the adjustment adjustment determination piston 18 of screw 21.

To illustrate that ring spring pin 22 can replace split pin 4 completely, it is identical with 4 role of split pin.

Annular spring catch can be installed with this utility model suspension clamp for electric line dress pin device, catenary clip back is solved The split pin in face come off after repair complex operation problem, it is time saving and energy saving, it is easy to use, be easy to carry, be adapted to onsite application.
