Preferably, offer several equidistantly adjustment holes spaced apart on described interior epoxy tube, described outer epoxy tube offers fixing hole with the end that described interior epoxy tube engages, described adjustable bottle-holding rack also comprises securing member, and described securing member is fixed outer epoxy tube and described interior epoxy tube through described fixing hole and described adjustment hole.
Preferably, on described interior epoxy tube, the spacing between two adjacent described adjustment holes is 90 millimeters.
Preferably, the overall length of described interior epoxy tube is 1 meter.
Preferably, offer two adjacent described fixing holes on described outer epoxy tube, the spacing between described two adjacent fixing holes is 90 millimeters.
Preferably, described securing member is by described interior epoxy tube and described outer epoxy tube regular length adjusting bolt after length adjustment completes.
Preferably, the total length of described adjustable bottle-holding rack is 3.9 meters～4.7 meters.
Preferably, described connecting plate and described end plate semicircular in shape.
Transmission line of the present utility model is changed the adjustable bottle-holding rack of insulator string, by epoxy tube being divided into to telescopic interior epoxy tube and outer epoxy tube, realize the adjustable in length of whole bottle-holding rack, described epoxy tube comprises interior epoxy tube and outer epoxy tube, described interior epoxy tube telescopically is set in the length of regulating described epoxy tube in described interior epoxy tube, can adapt to the insulator string of different length.Both save different circuits and made the funds without bottle-holding rack, also environmental protection more.
[accompanying drawing explanation]
Figure 1A, 1B are respectively preferred embodiment transmission line of the present utility model and change front view and the vertical view of insulator string with adjustable bottle-holding rack.
Fig. 2 is respectively the enlarged drawing of circle part in Figure 1A.
Fig. 3 is the schematic diagram after bottle-holding rack carries out length adjustment shown in Fig. 2.
[embodiment]
For understanding better the utility model, below with reference to accompanying drawing and instantiation, the utility model is described in detail.
Bottle-holding rack mainly is made by insulated tube (plate), is used for whole gravity of support insulator when changing insulator.Bottle-holding rack is arranged on the below of insulator string, after the corollary apparatus stringing lead, insulator string no longer bears wire tension, the gravity of its whole string all drops on bottle-holding rack, the operating personnel can be at the insulator string two ends, successively spring pin is extracted comparatively easily, insulator string is broken away to be changed.In order to make bottle-holding rack there is versatility, main design of the present utility model is that bottle-holding rack is made to telescopic in the longitudinal direction pattern, it is fixing after the different porcelain vase of every like this string sheet number stretches by the length to bottle-holding rack, can change, insulator string that just needn't each length is all done a bottle-holding rack.
Refer to Figure 1A and 1B, the transmission line that preferred embodiment of the present utility model provides is changed insulator string with adjustable bottle-holding rack as shown in FIG., and it comprises interior epoxy tube 10, epoxy rods 20, connecting plate 30, end plate 40, outer epoxy tube 50, length adjustment bolt 60 and bottle-holding rack suspension bracket 70.Interior epoxy tube 10 forms epoxy tubes with outer epoxy tube 50, epoxy tube with epoxy rods 20 according to being fastened in groove corresponding on connecting plate 30 toward middle mode by both sides.The two ends of epoxy tube and epoxy rods 20 tighten location with end plate 40.Two ends of the epoxy tube of each side are respectively equipped with bottle-holding rack suspension bracket 70, and bottle-holding rack suspension bracket 70 can freely rotate around stud respectively, and stud is fixed on the elliptical tube at bottle-holding rack two ends.For preventing that insulator string from horizontally slipping, connecting plate 30, end plate 40 semicirculars in shape.For the protection operator safety, all parts except there are suspension ring support and bolt support in two ends are the glass fibre reinforced plastic insulating material.
Please in conjunction with consulting Fig. 2 and Fig. 3, the standing part that outer epoxy tube 50 is epoxy bushing, it adopts epoxy insulation 60 * 40 elliptical tube processing and fabricatings to form, and interior epoxy tube 10 is the variable partition on epoxy tube, and its telescopically is set in interior epoxy tube 10.The overall length of interior epoxy tube 10 is 1.0 meters, and the spacing offered on it between several equidistantly 12, two adjacent adjustment holes 12 of adjustment hole spaced apart is 90 millimeters.The spacing that the end that outer epoxy tube 50 engages with interior epoxy tube 10 offers before two fixing holes, 52, two fixing holes 12 is identical with the spacing of adjustment hole 12, is 90 millimeters.Length adjustment bolt 60 is for fixing with outer epoxy tube 50 by interior epoxy tube 10 after completing in length adjustment.4.7 meters of the total lengths of bottle-holding rack, the length adjustment scope of bottle-holding rack is 3.9 meters～4.7 meters, can adapt to 23～28 porcelain insulator substrings.
During use, first according to the difference of line insulator length and gold utensil, carry out the entire length of holder for regulating bottle stand in advance.During conciliation, epoxy tube 10 in relatively outer epoxy tube 50 is flexible, until certain two the adjacent adjustment hole 12 on interior epoxy tube 10 with after fixing hole 52 on outer epoxy tube 50 aligns, with length adjustment bolt 60 through two holes and lock.After length adjustment is good, bottle-holding rack upper end (left end in Fig. 1) connects the shaft tower cross arm end by suspension bracket 70, its lower end (right-hand member in Fig. 1) is connected with insulator, untie insulator lower end butterfly macules bolt in live line working, assembly pulley by bottle-holding rack integral body by insulator by plumbness, the state that is up to the standard, and, in the cross-arm lower end, the staff just changes insulator on cross-arm again.
The above exemplifying embodiment has only been expressed part execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
