Accompanying drawing explanation
Fig. 1 is a kind of specific embodiment structural representation of adjustable anchor ear welding tooling described in the utility model;
In figure, Reference numeral name is called: 1-clamping plate 2-cross-arm fixed head 3-clamp bolt hole 4-crossarm bolt hole 5-fishbolt 6-jig.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Adjustable anchor ear welding tooling described in the utility model, comprise two semicircle anchor ears and fishbolt 5, two free ends of described semicircle anchor ear are connected with clamping plate 1 separately, on described clamping plate, there is clamp bolt hole 3, the arcuate midway point place of described semicircle anchor ear has jig 6, on described jig, be welded with the bearing of trend cross-arm fixed head 2 parallel with clamping plate bearing of trend, on described cross-arm fixed head, there is a plurality of crossarm bolts hole 4.
As shown in Figure 1, jig 6 be positioned at semicircle anchor ear arcuate midway point place away from the center of circle one side, original semicircle anchor ear outside is circular shape, during welding cross-arm fixed head and the bonding area of cross-arm fixed head limited, although can fill up by increasing scolder the mode reinforcement in gap between circular arc and cross-arm fixed head, but the weld strength that this mode obtains is both unstable, also improved manipulation strength, the utility model original pad place outside semicircle anchor ear increases jig, jig is a flat surfaces with certain area with semicircle anchor ear integral casting forming, by increasing the mode of bonding area, effectively strengthened the weld strength of cross-arm fixed head and anchor ear.The width of jig 6 is conventionally consistent with the width of semicircle anchor ear, and length can be arranged between 10-40 millimeter, and the too short weld strength of length is inadequate, and oversize processing cost and the weight that has increased semicircle anchor ear is unfavorable for high-altitude transmission of electricity installation and carries.
In general, the opening of anchor ear should not be greater than the diameter of electric pole, otherwise be difficult to clamp, and preferably equate, and the central angle of anchor ear is 180 degree, now clamps effect best.But in practical situations, the diameter of electric pole is often not of uniform size, therefore the central angle of circular anchor ear is preferably arranged on to 120-150 degree, can adapt to the pole diameter in wide region relatively.
More than one of clamp bolt hole 3 on every described clamping plate, is arranged in order along clamping plate bearing of trend.Adopt a plurality of clamp bolt holes along clamping plate bearing of trend spread configuration can adopt a plurality of fishbolts to clamp on the one hand simultaneously, increased chuck strength, simultaneously in the situation that only having a pair of fishbolt, the difference of the clamping bite that can cause according to the diameter difference of clamped electric pole, select different positions that fishbolt is installed, obtain good clamping effect, for example, when pole diameter is larger, fishbolt pitch of holes near electric pole is softened, fishbolt easily comes off after installing, now can select the clamp bolt hole away from from electric pole that fishbolt is installed.
For further strengthening chuck strength, the utility model can all be set to crossarm bolt hole and the internal thread of clamp bolt hole can coordinate with fishbolt, each clamp bolt hole all has a crossarm bolt hole corresponding with its position, makes fishbolt can pass successively the clamp bolt hole of the full hoop of two semicircles and corresponding crossarm bolt hole.Adopt fishbolt to continue to pass through the mode in clamp bolt hole and crossarm bolt hole, fishbolt plays the effect that clamps two anchor ears and fix two cross-arm fixed heads simultaneously, has further strengthened the degree of being connected firmly of cross-arm fixed head and anchor ear.
