Description
Technical field
The utility model relates to the automatics of automatically threading off between a kind of earth connection and action bars, especially a kind of using compressed air as the ground wire operating lever structure departing from power, belongs to power transformation fortune inspection equipment technical field.
Background technology
Existing method, when departing from action bars and earth connection, is all a side of holding capacity with grounding apparatus.Due to the diversity of grounding apparatus, such as wire, due to wire comparatively softness cannot bear more energetically, detach procedure is comparatively bothered; Such as bushing, if breakaway force is comparatively large, then easily causes device damage, leakage of oil, gas leakage etc.Therefore the unsuitable stress point as being separated earth connection and action bars of grounding apparatus.
Utility model content
The purpose of this utility model overcomes deficiency of the prior art, provides a kind of rational in infrastructure, avoid the pneumatic releasing structure of ground wire operating lever upper end because external force causes grounding apparatus to damage.
The pneumatic releasing structure of this ground wire operating lever upper end, comprise ground wire operating lever upper end body, described body interior is equipped with push-rod piston; Body is made up of earth connection termination draw-in groove, outer wall, permanent magnet and air flue; Push-rod piston is made up of push pedal, connecting rod and piston;
Earth connection termination draw-in groove is the axial groove opened on outer wall; Outer wall is tubular overcoat, and permanent magnet is cylindrical magnet iron, and inside axially has penetrating circular hole, and for the moving conduit of connecting rod, permanent magnet is secured by bolts on outer wall; Air flue is a cylindrical channel on insulating bar, as gas passage;
Push pedal is that nonferromugnetic material makes cylindrical plate; Piston is cylindrical piston, and size is mated with outer wall, and push pedal and piston are fixed as one by connecting rod; Piston and air flue form Simple air cylinder.
The beneficial effects of the utility model are: when not using of the present invention, in earth connection termination and action bars detach procedure, by equipment dead earth end, pull backward and extract action bars, directly stressed by equipment ground, easily cause device damage.By the present invention, eliminate the process pulled back, by compressed air as power, in action bars upper end, withdrawal lever and termination, avoid grounding apparatus stressed, namely decreases device damage.
Accompanying drawing explanation
Fig. 1 is the utility model front view.
Fig. 2 is the utility model vertical view.
Fig. 3 to Fig. 5 is the utility model active state schematic diagram.
Description of reference numerals: body 1, earth connection termination draw-in groove 1-1, outer wall 1-2, powerful permanent iron 1-3, air flue 1-4, push-rod piston 2, push pedal 2-1, connecting rod 2-2, piston 2-3.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified model and equivalent.
Shown in Fig. 5, the pneumatic releasing structure of ground wire operating lever upper end of the present embodiment, comprises ground wire operating lever upper end body 1, and push-rod piston 2 is equipped with in described body 1 inside; Body 1 is made up of earth connection termination draw-in groove 1-1, outer wall 1-2, powerful permanent iron 1-3 and air flue 1-4; Push-rod piston 2 is made up of push pedal 2-1, connecting rod 2-2 and piston 2-3;
Earth connection termination draw-in groove 1-1 is the axial groove opened on outer wall 1-2; Outer wall 1-2 is tubular overcoat, and permanent magnet 1-3 is cylindrical magnet iron, and inside axially has penetrating circular hole, and for the moving conduit of connecting rod 2-2, permanent magnet 1-3 is fixed on outer wall 1-2 by methods such as bolts; Air flue 1-4 is a cylindrical channel on insulating bar, as gas passage;
Push pedal 2-1 is that nonferromugnetic material makes cylindrical plate; Piston 2-3 is cylindrical piston, and size is mated with outer wall, and push pedal 2-1 and piston 2-3 is fixed as one by connecting rod 2-2; Piston 2-3 and air flue 1-4 forms Simple air cylinder.
Utility model works principle is:
Normal operating conditions, earth connection termination holds with powerful attraction by permanent magnet 1-3, and permanent magnet 1-3 and earth connection termination are contacted by push pedal 2-1.
When earth connection and action bars depart from by needs, the present invention is using compressed air as power, compressed air enters cylinder by air flue 1-4, promote piston upwards, move upward with connecting rod promotion push pedal 2-1 and earth connection termination simultaneously, earth connection termination to going out action bars upper end, is completed earth connection termination and action bars disengaging operation by push pedal 2-1.
As shown in Figure 3.State 1: initial state of termination, due to the suction-combining force, earth connection termination is by push pedal 2-1 to pressing down, and push pedal 2-1 is contacted with permanent magnet 1-3, and piston 2-3 is in extreme lower position.
As shown in Figure 4.State 2: because Compressed Gas enters cylinder by air flue, promotes piston 2-3 and moves upward, and piston 2-3 promotes push pedal 2-1 by connecting rod 2-2 and earth connection termination moves upward.
As shown in Figure 5.State 3: action bars upper end is released in earth connection termination by push pedal 2-1, and piston 2-3 is positioned at top.Earth connection termination has been separated with action bars upper end.Then return to form 1.
