Description
Technical field
The utility model relates to a kind of securing member, especially a kind of movable cross-arm anchor ear.
Background technology
Along with developing rapidly of China's electric utility, in transmission line construction, transformation, except part transmission line of electricity changes into except cable laying, most transmission line of electricity still adopts built on stilts form.In power construction operation, long need cross-arm, in the installations such as T extension bar and shaft tower main body, it connects by fixing meanss such as welding, bolts, in the later stage, needs larger energy when transforming tower bar, circuit, impact transformation and power off time, cause economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of movable cross-arm anchor ear, can be applied to and connect T extension bar and shaft tower main body, and fixing T extension bar is in shaft tower upper shell adjustment position and angle, is convenient to transmission line of electricity transformation.
For reaching appeal object, the technical solution of the utility model is as follows: a kind of movable cross-arm anchor ear, comprise left half anchor ear and right half anchor ear, described left half anchor ear comprises left clamping part and left installation portion, and described right half anchor ear comprises right clamping part, right installation portion and extends firmware; Described left clamping part and right clamping part are the half of dodecagon, described left installation portion and right installation portion are respectively the extension plates at left clamping part and right clamping part two ends, described extension firmware is positioned at the centre of the right clamping part of right half anchor ear, on dodecagonal.
Improve as one, described left half anchor ear and right half anchor ear composition clamping chamber, described clamping chamber is dodecagon.
Improve as one, described left installation portion and right installation portion upper and lower side extend into horizontal extension plate, left installation portion is parallel relatively with the horizontal extension plate on right installation portion, and its relative distance is adjustable according to body of rod diameter, and horizontal extension plate width is consistent with the width of left clamping part and right clamping part.
Improve as one, each horizontal extension plate of described left installation portion and right installation portion has four bolts hole, and in array distribution, described bolt hole aperture and bolt directly match.
Improve as one, described extension firmware is made up of two parallel foursquare steel plates relatively, its relative distance is the dodecagonal length of side, and the cross section of the extension firmware of composition is square, and its foursquare length of side is consistent with the width of left clamping part and right clamping part.
Improving as one, two foursquare steel plates of described extension firmware respectively having four bolts hole of the isometrical arrangement of straight line, for installing T extension bar.
Adopt movable cross-arm anchor ear of the present utility model, can first T extension bar be connected with anchor ear on the ground, then the cross-arm of installation activity aloft anchor ear, adjustment activity anchor ear direction, makes T extension bar be installed on shaft tower.The time of constructing can be reduced so aloft, increase safety and the Discussing Convenience of construction, accelerate efficiency of construction, thus save power off time to transformation circuit.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, in the utility model, movable anchor ear is made up of left and right two and half hoops, and a described left side half anchor ear comprises left clamping part 1 and left installation portion 3, and described right half anchor ear comprises right clamping part 2, right installation portion 4 and extends firmware 5; Described left clamping part 1 and right clamping part 2 are the half of dodecagon, described left installation portion 3 and right installation portion 4 are respectively the extension plates at left clamping part 1 and right clamping part 2 two ends, described extension firmware 5 is positioned at the centre of the right clamping part 2 of right half anchor ear, on dodecagonal.
As a kind of detailed description of the invention of improvement, described left and right two and half anchor ear composition clamping chambeies, described clamping chamber is dodecagon, and clamping chamber holds shaft tower main body, by installation portion adjustment clamping chamber size.
As a kind of detailed description of the invention of improvement, described anchor ear installation portion extends into horizontal extension plate by half hoop upper and lower side, the horizontal extension plate of the installation portion of left and right half anchor ear is relatively parallel, each horizontal extension plate of described installation portion there are four bolts hole, in array distribution, described bolt hole aperture and the diameter of bolt match; The relative distance of horizontal extension plate is adjustable to be regulated by bolt degree of tightness.Shaft tower main body at various height its diameter is different, and the horizontal extension plate of two and half anchor ears is bolted, directly also can regulate and control the degree of tightness of bolt according to different shaft tower section, thus the shaft tower adapting to different-diameter size; The width of described horizontal extension plate is consistent with clamping part width.
As a kind of detailed description of the invention of improvement, the extension firmware 5 of right half anchor ear is made up of two parallel foursquare steel plates relatively, its relative distance is the dodecagonal length of side, and the cross section of the extension firmware 5 of composition is square, and its foursquare length of side is consistent with the width of half anchor ear clamping part.Two foursquare steel plates respectively have four bolts hole of the isometrical arrangement of straight line, for installing T extension bar.
Adopt movable cross-arm anchor ear of the present utility model, first T extension bar can be connected with anchor ear on the ground, the cross-arm of installation activity aloft anchor ear again, T extension bar is made to be installed on shaft tower, reduce the time of constructing aloft, increase safety and the Discussing Convenience of construction, accelerate efficiency of construction, thus save power off time to transformation circuit.Meanwhile, movable cross-arm anchor ear is not directly fixed with shaft tower, when transforming transmission line of electricity, adjustment activity anchor ear direction can be passed through, bolt etc. on absent-mindedness anchor ear is transformed circuit, enhances the convenience form of transformation circuit, and saves financial cost.
