Description
Technical field
The utility model relates to a kind of steel tube tower, particularly a kind of cross-arm.
Background technology
Along with Chinese society rapid development of economy, electricity need load progressively increases, and ultra-high-tension power transmission line enters city becomes development trend.Steel pipe pole has that structure is simple, intensity is high, handsome in appearance, the process-cycle is short, floor space is few, transport and the advantage such as to save time easy for installation, be applicable to the poles such as the different voltages of multiloop joint use, develop with modern city and coordinate mutually, be widely used in the construction of 10-220kv transmission line of electricity.But because the cross-arm that steel pipe pole is arranged directly is connected by welding manner with mobile jib, make troubles, and cross-arm generally adopts pipe to the installation of cross-arm, its application life is not long.
Utility model content
The purpose of this utility model is to provide a kind of EHV transmission steel tube tower cross-arm connector, and it is easy for installation, and structural stability is better, longer service life.
The purpose of this utility model is achieved in that a kind of EHV transmission steel tube tower cross-arm connector, comprise the mobile jib fixed on the ground by flange in the bottom, described mobile jib is formed by Flange joint by the above conical hollow bar of two joints, mobile jib is welded with two groups of wing plates, wing plate offers the installing hole axially tilted along mobile jib, described installing hole is from top to bottom outwards arranged gradually.
Compared with prior art, the beneficial effects of the utility model are, the utility model installs fixing cross-arm by using bolt, it is reliably easier for installation, structural stability is better, longer service life, when the installing hole of inclination ensure that cross-arm is stressed, stress distribution is more even, improves structural stability further.The utility model can be used in transmission line of electricity.
In order to strengthen stability fixing between wing plate and mobile jib, between described wing plate and mobile jib, be welded with stiffened panel.
In order to make cross-arm easier for installation, described wing plate is provided with cross-arm through bolt, the end end face of described cross-arm is fixed with jumper wire board.
In order to increase the scope of application of utility model, the bottom surface of described cross-arm is fixed with thread gripping-board.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is the structural representation after the utility model installs cross-arm.
Wherein, 1 mobile jib, 2 stiffened panels, 3 wing plates, 4 installing holes, 5 cross-arms, 6 jumper wire boards.
Detailed description of the invention
A kind of EHV transmission steel tube tower cross-arm connector as Figure 1-3, comprise the mobile jib 1 fixed on the ground by flange in the bottom, mobile jib 1 is formed by Flange joint by the above conical hollow bar of two joints, mobile jib 1 is welded with two groups of wing plates 3, wing plate 3 offers the installing hole 4 axially tilted along mobile jib 1, installing hole 4 is from top to bottom outwards arranged gradually, be welded with between wing plate 3 and mobile jib 1 on stiffened panel 2 wing plate 3, through bolt, cross-arm 5 be installed, the end end face of cross-arm 5 is fixed with jumper wire board 6, and the bottom surface of cross-arm 5 is fixed with thread gripping-board.
The utility model installs fixing cross-arm 5 by using bolt, and it is reliably easier for installation, and structural stability is better, longer service life, and when the installing hole 4 of inclination ensure that cross-arm 5 is stressed, stress distribution is more even, improves structural stability further.
The utility model is not limited to above-described embodiment; on the basis of technical scheme disclosed in the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some to some technical characteristics wherein to replace and distortion, these are replaced and are out of shape all in protection domain of the present utility model.
