Description

Suspension clamp for electric line dress pin device

Technical field

The present invention relates to a kind of live line tool, and in particular to a kind of suspension clamp for electric line dress pin device.

Background technology

On transmission line of electricity straight line pole, suspension clamp that wire is connected with insulator（Such as Fig. 1）Turned using hanger add-back Axle mode is attached, and prevents hanger from coming off with pad and split pin at the both ends of gyroaxis.But due to circuit long-play, It sometimes appear that the critical defect that split pin comes off, is such as added, it may occur however that the accident that wire drops not in time.Add and typically adopt With livewire work, because the split pin that some suspension clamps are the back side comes off, people does not see on shaft tower, split pin is not pacified Dress, insulator and suspension clamp can only be disconnected, allow suspension clamp to turn a direction, could install, repair complex operation, it is time-consuming to take Power.

The content of the invention

The purpose of the present invention provides a kind of suspension clamp for electric line dress pin device exactly in order to overcome above mentioned problem.

The technical solution adopted by the present invention is：

A kind of suspension clamp for electric line dress pin device, including mounting head, extension rod, sleeve, wheel disc, action bars pitman, Pipe collar, pipe collar screw, mirror holder, eyeglass；There is pipe collar on described action bars pitman, there is pipe collar screw on pipe collar, pipe collar leads to Cross pipe collar screw to be connected with mirror holder, there is eyeglass on mirror holder；It is characterized in that：Extension rod is welded with described mounting head, is extended Bar is connected through sleeve with wheel disc, and wheel disc can drive extension rod to be rotated in sleeve；Action bars pitman is welded with sleeve； Mounting head includes pipe, piston, there is symmetrical twice keyway on round tube inner wall, and pipe front end keyway penetrates with small gap, pipe Rear end keyway is penetrated with long gap and welded with extension rod；There is piston in pipe, sliding block is connected with piston, sliding block can be in keyway There are small lugs interior slip, sliding block rear end, and small lugs stretch out from long gap；Piston centre has adjustment screw, for adjusting piston Movement travel；Piston movement can not be deviate to front end by small lugs limitation.

Compared with the prior art, the invention has the advantages that：Annular spring catch can be installed, solve catenary clip back The split pin in face come off after repair complex operation the problem of, it is time saving and energy saving, it is easy to use, be easy to carry, be adapted to onsite application.

Embodiment

Fig. 1 is the structural representation of suspension clamp；Fig. 2 is Fig. 1 left view；Suspension clamp uses the add-back rotating shaft 2 of hanger 1 Mode is attached, and has pad 3 and split pin 4 at the both ends of gyroaxis 2.But it sometimes appear that the problem of split pin comes off, such as Add not in time, it may occur however that the accident that wire drops.Add and typically use livewire work, 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 suspension clamp for electric line dress pin device embodiment of the present invention；Fig. 4 is Fig. 3 left view；This hair 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；There is pipe collar 10 on described action bars pitman 9, there is pipe collar spiral shell on pipe collar 10 Silk 11, pipe collar 10 is connected by pipe collar screw 11 with mirror holder 12, there is eyeglass 13 on mirror holder 12；It is characterized in that：Described installation Extension rod 6 is welded with first 5, extension rod 6 is connected through sleeve 7 with wheel disc 8, and wheel disc 8 can drive extension rod 6 in sleeve 7 Rotate；Action bars pitman 9 is welded with sleeve 7；Fig. 5 is the sectional view of mounting head 5；Fig. 6 is Fig. 5 top view；Fig. 7 is figure 5 left view, mounting head 5 include pipe 14, piston 18, have symmetrical twice keyway 15, the front end of pipe 14 on the inwall of pipe 14 Keyway 15 is penetrated with small gap 16, and the rear end keyway 15 of pipe 14 is penetrated with long gap 17 and welded with extension rod 6；Have in pipe 14 Piston 18, sliding block 19 is connected with piston 18, sliding block 19 can slide in keyway 15, and the rear end of sliding block 19 there are small lugs 20, small convex Block 20 stretches out from long gap 17；There is adjustment screw 21 at the center of piston 18, and for adjusting the movement travel of piston 18, Fig. 8 is piston 18 move to the schematic diagram of rear end, and Fig. 9 is Fig. 8 top view；Piston 18 moves to front end can not be deviate from by the limitation of small lugs 20. Catch 24 is welded with extension rod 6, for preventing the axial float in sleeve 7 of extension rod 6.

In use, the action bars pitman 9 that suspension clamp for electric line of the present invention is filled to pin device is connected with insulating bar, Eyeglass 13 is adjusted to appropriate angle, fixed insulation rope and several circles are wound 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, and ring is put into small gap 16 The opening termination of shape spring catch 22, the opening termination of ring spring pin 22 are prevented in opening shape by the sliding block 19 on piston 18 State；In the case where ensureing safe distance, make extension rod 6 vertical with wire, look at eyeglass 13 and allow the alignment of the center of mounting head 5 to turn round Axle 2 come off split pin one end promote, it is that gyroaxis 2 pushes up piston 18 to rear end that gyroaxis 2, which pushes up piston 18 to rear end, Figure 11, 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 is fallen into back Untill in the pin-and-hole 23 of rotating shaft 2, suspension clamp for electric line dress pin device of the present invention, installation are extracted out.Figure 12 is installation Schematic diagram.

During installation, if the stroke that piston 18 moves 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 that piston 18 moves 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 moved according to the distance adjustment piston 18 of pin-and-hole 23 to the termination of gyroaxis 2, 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, it is identical with the role of split pin 4.

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