Specific embodiment
Below in conjunction with specific embodiment and attached drawing 1-6, the technical solution in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only a part of preferred embodiment of the present invention, instead of all the embodiments.
Those skilled in the art can do similar deformation without violating the connotation of the present invention, therefore the present invention is not by described below
Specific embodiment limitation.
The present invention provides a kind of transmission line of electricity parallel groove clamp fast assembling-disassembling auxiliary tool (as shown in Figure 1), including wire clamp
Clamping device, hollow insulating bar 5 and insulated tension pole 4；The wire clamp clamping device includes L-type active chuck 1 and fixed top plate 2,
One supporting rod 22 is set in the trailing flank of the fixed top plate 2, the middle part of the supporting rod 22 is hinged on the hollow insulating bar 5
In one supporting vertical plate 52 of top setting, in this embodiment, supporting vertical plate 52 is buckled in hollow by firm banking 51
The top of insulating bar 5 also sets up a semiclosed rectangular guide groove 21 in the trailing flank of the fixed top plate 2, and described semiclosed
Rectangular guide groove 21 is located at right over the supporting rod 52 (as shown in Figure 5), in the rear end of the semiclosed rectangular guide groove 21
Setting one carries the limiting plate 211 of through-hole, setting one and the semiclosed rectangular guiding in the side of the L-type active chuck 1
The matched rectangular guide rod 112 of slot 21 is oriented to round bar 115 in rectangular 112 rear end of the guide rod setting one, described rectangular to lead
It being nested in the semiclosed rectangular guide groove 21 to bar 112, the guiding round bar 115 is nested in the limiting plate 211,
115 rear end of the guiding round bar is nested with a spring 114, and the spring 114 is located at limiting plate 211 with being oriented to 115 rear end of round bar
Between one pressure plate 113 of setting, L-type active chuck 1 is fixed 2 side wall of top plate under the action of spring 114 and is close to, so as to make
L-type active chuck 1 and the combination of fixed top plate 2 form a parallel groove clamp holding chamber, because spring 114 has a retractility, therefore L-type
1 Telescopic movable of active chuck expands the range of wire clamp gripping apparatus grips wire clamp in this way, in order to enable wire clamp clamping device
Smoothly parallel groove clamp can be snapped onto between L-type active chuck 1 and fixed top plate 2, here, in the side of L-type active chuck 1
12 times bottom ends of plate set an oriented plate 13, after oriented plate 13 is contacted with the one side of parallel groove clamp, can take advantage of a situation down
Whole device is drawn, smoothly realizes being caught in for parallel groove clamp, further, the entire stringer length to ensure parallel groove clamp is respectively positioned on
Between L-type active chuck 1 and fixed top plate 2, here, setting a positioning plate 14 in the side of tablet 11, it is caught in parallel groove clamp
To after between L-type active chuck 1 and fixed top plate 2, staff can drag whole device along the length direction of parallel groove clamp,
So that positioning plate 14 and the one end of parallel groove clamp fit closely.To ensure when dismantling the nut in parallel groove clamp, L-type activity
Collet 1 will not be open-top by the torque suffered by parallel groove clamp, here, threaded rod is set as by round bar 115 is oriented to, by pressure plate 113
Nut is set as, by position of the adjusting nut on threaded rod, it can be achieved that the different precompressed amount of spring 114, so as to improve L
Dynamics is bonded between type active chuck 1 and fixed top plate 2.
The insulated tension pole 4 is nested in the hollow insulating bar 5, and the top of the insulated tension pole 4 passes through a connecting rod 3
It is connected with the rear end of the supporting rod 22, the connecting rod 3 and the insulated tension pole 4 and the supporting rod 22 are in hinged way
Connection, the lower end of the insulated tension pole 4 is threaded rod 41, and an adjusting nut 6, and the adjusting nut are nested on threaded rod 41
6 upper surface fits with hollow 5 bottom surface of insulating bar, in practical applications, can be realized by rotating adjusting nut 6
Insulated tension pole 4 moves up and down, and so as to realize the rotation of supporting rod 22, the supporting rod 22 exists in this embodiment
(including 0 °, 90 °) between the range of rotatable angle [alpha] is arranged on 0 ° -90 ° under the promotion of insulated tension pole 4.Because of insulated tension pole 4
It is longer, be to reduce insulated tension pole 4 during moving up, resistance that suffered connecting rod 3 is given and generate larger amount of deflection,
This, sets a guide cylinder 53 to fit with insulated tension pole 4, in guide cylinder 53 in hollow 5 inner tip upper position of insulating bar
Guiding role under, 4 upper end of insulated tension pole can be disposed up and down motion, so as to can also improve 22 rotation angle of supporting rod can
Control property.
In practical applications, clamp nut all tiltedly towards lower ground, utilizes the adjusting in the present apparatus on general parallel groove clamp
The angle of inclination that nut 6 adjusts supporting rod 22 may be such that inclined parallel groove clamp is smoothly caught in, and live when parallel groove clamp snaps onto L-type
After between dynamic collet 1 and fixed top plate 2, then by adjusting nut 6 it may be such that supporting rod 22 is horizontal positioned so that on parallel groove clamp
Clamp nut downwards, be conducive to staff in this way and clamp nut remotely dismantled by specific purpose tool on ground.One
A bit in special circumstances, the clamp nut on parallel groove clamp vertically upward, in order to the present apparatus can realize in such cases and ditch
Wire clamp is fixed, here, a slotted hole 111 is opened up on the tablet of L-type active chuck, when clamping is fixed, and ditch
The clamp nut of wire clamp is located at slotted hole 111, and gripping, but in this case for parallel groove clamp, work equally can be achieved in this way
Dismantlement work can only be realized by dismantling the fastening bolt on parallel groove clamp by making personnel.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
The above combination attached drawing is described above in detail the preferred embodiment of the present invention and embodiment, but the present invention is not
The above-described embodiment and examples are confined to, for those skilled in the art, are not departing from structure of the present invention
Under the premise of think of, several improvement and modification can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
