Specific embodiment

Fig. 1 is the structural representation of suspension clamp；Fig. 2 is the left view of Fig. 1；Suspension clamp adopts hanger 1 add-back rotating shaft 2 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 it may occur however that the accident that drops of wire not in time.Add and typically adopt livewire work, if the back side one that people can't see The split pin of side comes off, band point add operation extremely complex, waste time and energy.

Embodiment

Fig. 3 is the schematic diagram of suspension clamp for electric line dress pin device embodiment of the present invention；Fig. 4 is the left view of Fig. 3；This Bright suspension clamp for electric line dress pin device, including mounting head 5, extension rod 6, sleeve 7, wheel disc 8, action bars pitman 9, pipe collar 10th, pipe collar screw 11, mirror holder 12, eyeglass 13；Pipe collar 10 is had on described action bars pitman 9, pipe collar 10 has pipe collar spiral shell Silk 11, pipe collar 10 is connected with mirror holder 12 by pipe collar screw 11, and mirror holder 12 has eyeglass 13；It is characterized in that：Described installation It is welded with extension rod 6, extension rod 6 is connected through sleeve 7 with wheel disc 8, and wheel disc 8 can drive extension rod 6 in sleeve 7 on 5 Rotate；Action bars pitman 9 is welded with sleeve 7；Fig. 5 is the sectional view of mounting head 5；Fig. 6 is the top view of Fig. 5；Fig. 7 is figure 5 left view, mounting head 5 includes pipe 14, piston 18, and pipe 14 inwall has symmetrical twice keyway 15, pipe 14 front end Keyway 15 and the insertion of little gap 16, pipe 14 rear end keyway 15 welds with the insertion of long gap 17 and with extension rod 6；Have in pipe 14 Piston 18, piston 18 is connected with slide block 19, and slide block 19 can slide in keyway 15, and there are small lugs 20 slide block 19 rear end, little convex Block 20 stretches out from long gap 17；There is adjustment screw 21 at piston 18 center, and for adjusting the movement travel of piston 18, Fig. 8 is piston 18 schematic diagrams moving to rear end, Fig. 9 is the top view of Fig. 8；Piston 18 moves to front end and is limited to deviate from by small lugs 20. Catch 24 is welded with extension rod 6, for stoping extension rod 6 axial float in sleeve 7.

During use, the action bars pitman 9 that suspension clamp for electric line of the present invention is filled pin device is connected with insulating bar, Eyeglass 13 is adjusted to suitable angle, fixed insulation rope be wound around several circles on wheel disc 8；Adjustment adjustment screw 21 determines piston 18 Stroke；Stirring small lugs 20 makes piston 18 move to front end, and Figure 10 is SBR schematic diagram, puts into ring in little gap 16 The opening termination of shape spring catch 22, the opening termination of ring spring pin 22 is stoped to be in by the slide block 19 on piston 18 opens shape State；In the case of ensureing safe distance, make extension rod 6 vertical with wire, look at eyeglass 13 and allow mounting head 5 center be aligned to turn round Axle 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 rear end by gyroaxis 2 Schematic diagram, now the opening termination of ring spring pin 22 be seized gyroaxis 2, pull insulating cord, wheel disc 8 passes through extension rod 6 Mounting head 5 is driven to rotate, mounting head 5 drives ring spring pin 22 to rotate, until the opening termination of ring spring pin 22 falls into back Till in the pin-and-hole 23 of rotating shaft 2, extract suspension clamp for electric line dress pin device of the present invention, installation out.Figure 12 is installation Schematic diagram.

During installation, if the stroke of piston 18 motion is too short, do not arrive pin-and-hole 23 in the opening termination of ring spring pin 22 Position, do not install；If the stroke of piston 18 motion 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 of piston 18 motion will be adjusted according to the distance that pin-and-hole 23 arrives gyroaxis 2 termination, It is exactly the stroke that adjustment adjustment screw 21 determines piston 18.

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

Fill pin device with suspension clamp for electric line of the present invention and annular spring catch can be installed, solve the suspension clamp back side Split pin come off after repair complex operation problem, time saving and energy saving, easy to use, be easy to carry, be suitable for onsite application.
