[embodiment]
The technical scheme of accompanying drawing to the embodiment of the present invention below in conjunction with the embodiment of the present invention is explained and illustrated, but following embodiment is only the preferred embodiments of the present invention, and not all.Based on the embodiment in execution mode, those skilled in the art under the prerequisite not making creative work obtain other embodiment, all belong to protection scope of the present invention.
With reference to figure 2, Fig. 3 and Fig. 4, shown a kind of plug-in strip operating means, comprise action bars 1 and joint 3, action bars 1 splits with joint 3 and is connected, joint 3 comprises pedestal, pedestal is provided with two pieces of risers 31 that homonymy extends, and riser 31 is provided with hook groove 311, and the two ends of action bars 1 are respectively equipped with joint pin 5 and sleeve pipe 2.Insert plug-in strip handle hole by the joint pin 5 on action bars 1 to operate the plug-in strip that plug-in strip operates pass; With reference to figure 3, be socketed plug-in strip bar 43 by sleeve pipe 2 and can contrast the plug-in strip with plug-in strip bar 43 and operate; With reference to figure 2, be connected by action bars 1 with joint 3, the hook groove 311 on riser 31 connects plug-in strip rotation axis 42 and can operate the plug-in strip with plug-in strip rotation axis; Therefore the plug-in strip operation of the compatible multiple transformer station of plug-in strip operating means of the present invention, can complete the operation to common three types plug-in strip.
With reference to figure 1, Fig. 2, Fig. 4 and Fig. 5, pedestal comprises base plate 32, the side of base plate 32 arranges riser 31, the opposite side of base plate 32 is provided with pipe 33, the diameter of pipe 33 is greater than the diameter of action bars 1, therefore joint pin 5 and pipe 33 can be connected the plug-in strip handle hole 41 of different-diameter, strengthen applicability and the serviceability of plug-in strip operating means further.With reference to figure 1, action bars 1 is connected with joint 3, pipe 33 outwardly time, pipe 33 can connect plug-in strip handle hole 41; With reference to 2, action bars 1 is connected with joint 3, riser 31 outwardly time, hook groove 311 can connect plug-in strip rotation axis 42.
With reference to figure 1, Fig. 3, Fig. 4 and Fig. 5, the fractionation connected mode of action bars 1 and joint 3: have through hole 331 in pipe 33, and through hole 331 runs through base plate 32, joint pin 5 is connected with through hole 331, thus realizes action bars 1 and be connected with joint 3.With reference to 2, joint 3 is mounted to after joint pin 5 from pipe 33 end, and riser 31 exposes and can operate plug-in strip rotation axis 42; With reference to figure 1, joint 3 is mounted to after joint pin 5 from riser 31 end, and pipe 33 exposes and can operate plug-in strip handle hole 41.Therefore joint 3 is from these two different directions attended operation bars 1, the plug-in strip operation tool of not same-action both just being formed.
With reference to figure 3, Fig. 4 and Fig. 5, joint pin 5 is provided with block 51, limits by block 51 length that joint pin 5 stretches into through hole 331, to make pipe 33 and plug-in strip handle hole precise match.
Joint pin 5 is provided with elastic protrusion 61, and through hole 331 is provided with the Access Division of corresponding elastic protrusion 61, and when block 51 and joint 3 offset, elastic protrusion 61 connects Access Division.By the cooperation of elastic protrusion 61 and Access Division, after action bars 1 is connected with joint 3, both relative motions are limited, certain External Force Acting just can make that action bars 1 is relative with joint 3 to be detached, therefore split conveniently, reduce device assembling and the time required for conversion, improve operating efficiency.In other embodiments of the invention, joint pin is connected with through hole whorl, and the mode be threaded connection realizes the fractionation of action bars and joint.
Screw 6 is connected with at the end of joint pin 5, the periphery of screw 6 arranges elastic protrusion 61, Access Division is the chamfering 332 being arranged on the axial two ends of through hole 331, screw 6 is through through hole 331, after block 51 and joint 3 offset, elastic protrusion 61 offsets right through through hole 331 and chamfering 332, can limit action bars 1 and joint 3 relatively rotating and mobile.Chamfering 332 is annular, and therefore elastic protrusion 61 can be inserted into through hole 331 from arbitrarily angled, does not need to regulate to aim at.When needing fractured operation bar 1 and joint 3, joint 3 is fixed, drive action bars 1 to move axially along through hole 331, the effect of the chamfering 332 passed through, be pressed into elastic protrusion 61 gradually, then just action bars 1 can be separated with joint 3.
Further, action bars 1 comprises the first pole 12 and one end of the second pole 11, first pole 12 and one end of the second pole 11 and is slidably connected, and the other end of the first pole 12 arranges joint pin 5, and the other end of the second pole 11 arranges sleeve pipe 2.Because in power transformation box, equipment is various, can the length of adjustment operation bar 1 to the interference of operation for avoiding other equipment, and the arm of force of rotation can be increased by the length that relative sliding first pole 12 and the second pole 11 extend action bars 1, operate more laborsaving; The size of device can be reduced by the length of relative sliding first pole 12 and the second pole 11 reduction operation bar 1, carry convenient.
Concrete, second pole 11 is socketed with back-up ring 13, the end of the second pole 11 is connected with guide vane end stop 15, guide vane end stop 15 is arranged on the end face of the second pole 11 by bolt 14, first pole 12 is provided with connecting hole 121, and after the second pole 11 and guide vane end stop 15 are mounted to connecting hole 121, back-up ring 13 and the first pole 12 are by being welded and fixed, and the diameter of back-up ring 13 is greater than the diameter of the second pole 11, the diameter of back-up ring 13 is less than the diameter of the endoporus of back-up ring 13.Therefore the first pole 12 can be slided in connecting hole 121, and spacing by the stop of back-up ring 13 pairs of guide vane end stops 15, can prevent the first pole 12 and the second pole 11 from departing from.
Further, the endoporus of back-up ring 13 and the radial section of the second pole 11 are D shape, therefore the second pole 11 can moving axially along back-up ring 13 endoporus, and limit relatively rotating of the first pole 12 and the second pole 11, be beneficial to the transmission of actuating force, be convenient to be operated plug-in strip by plug-in strip operating means.
In addition, inner sleeve can also be set in sleeve pipe, the sidewall of inner sleeve is provided with distortion groove vertically, the sidewall of sleeve pipe is provided with screwed hole, and screwed hole is symmetrically distributed in the both sides of sleeve pipe, and screw rod is fixedly connected with the outer wall of inner sleeve through screwed hole, screw and screwed hole threaded engagement, inner sleeve can be made to be out of shape by rotating screw bolt, inner sleeve distortion produces different internal diameters, to coordinate with the plug-in strip bar of different pore size.
By above-described embodiment, object of the present invention is reached by fully effective.The personage being familiar with this technology should be understood that and the present invention includes but the content being not limited to accompanying drawing and describing in embodiment above.Any amendment not departing from function and structure principle of the present invention all will comprise within the scope of the appended claims.
