Description
Technical field
The utility model relates to a kind of power equipment, particularly a kind of steel tube tower.
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 extra high voltage network terminal steel tube tower, and its structural stability is better, longer service life, and reliably easier for installation.
The purpose of this utility model is achieved in that a kind of extra high voltage network terminal steel tube tower, 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, described mobile jib is from top to bottom provided with ground connection cross-arm successively in pairs, first cross-arm, second cross-arm and the 3rd cross-arm, transition frame is provided with in the middle part of second cross-arm and the 3rd cross-arm, mobile jib between first cross-arm and the second cross-arm is fixed with cable bearer, cable bearer comprises the tube connector be welded on mobile jib, the welding edges of tube connector has support bar, support bar is welded with transition frame.
Compared with prior art, the beneficial effects of the utility model are, in the utility model, mobile jib is segmentation structure, handling ease, and easy construction is safe and reliable to operation, reduce labour intensity, safeguard that work amount is few; The features such as segmentation mobile jib is connected by abutted flange, and stable connection is not yielding, can bear larger load, easy to use; Arrange in the middle part of the second cross-arm, the 3rd cross-arm and the transition frame that support bar is arranged, cable enters transformer station along transition frame in the air from height, thus makes the transmission of cable in good order, and transition frame structure is simple, with low cost.The utility model can be used in electric power conveying equipment.
In order to reduce the manufacturing cost of transition frame further, described transition frame comprises the channel-section steel that welding edges has flange.
In order to avoid mutually disturbing between cable further, described cable bearer is arranged on side perpendicular with cross-arm installed surface on mobile jib.
In order to make maintenance convenient, on mobile jib, the another side of installing cables support is provided with cat ladder.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is mobile jib in the utility model, cross-arm, cat ladder, cable bearer arrangement schematic diagram.
Fig. 3 is transition frame structural representation in the utility model.
Wherein, 1 ground connection cross-arm, 2 first cross-arms, 3 second cross-arms, 4 the 3rd cross-arms, 5 transition frame, 5a channel-section steel, 5b flange, 6 cable beareves, 7 mobile jibs, 8 cat ladders.
Detailed description of the invention
A kind of extra high voltage network terminal steel tube tower as Figure 1-3, comprise the mobile jib 7 fixed on the ground by flange in the bottom, mobile jib 7 is formed by Flange joint by the above conical hollow bar of two joints, mobile jib 7 is from top to bottom provided with ground connection cross-arm 1 successively in pairs, first cross-arm 2, second cross-arm 3 and the 3rd cross-arm 4, transition frame 5 is provided with in the middle part of second cross-arm 3 and the 3rd cross-arm 4, mobile jib 7 between first cross-arm 2 and the second cross-arm 3 is fixed with cable bearer 6, cable bearer 6 comprises the tube connector be welded on mobile jib 7, the welding edges of tube connector has support bar, support bar is welded with transition frame 5, transition frame 5 comprises the channel-section steel 5a that welding edges has flange 5b, cable bearer 6 is arranged on side perpendicular with cross-arm installed surface on mobile jib 7, on mobile jib 7, the another side of installing cables support 6 is provided with cat ladder 8.
In the utility model, mobile jib 7 is segmentation structure, handling ease, and easy construction is safe and reliable to operation, reduces labour intensity, safeguards that work amount is few; The features such as segmentation mobile jib 7 is connected by abutted flange, and stable connection is not yielding, can bear larger load, easy to use; Arrange in the middle part of the second cross-arm 3, the 3rd cross-arm 4 and the transition frame 5 that support bar is arranged, cable enters transformer station along transition frame 5 in the air from height, thus makes the transmission of cable in good order, and transition frame 5 structure is simple, with low cost.
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.
