Abstract
The utility model discloses a four tubs - single tube of narrow basic steel pipe pole conversion node for connect single tube steel pipe pole and four tubs of steel pipe poles in the power transmission and transformation circuit, characterized by, linking module, main part and linking module down on welded in proper order, linking module is provided with four down, and difference evenly distributed is in the bottom of main part. The utility model discloses the beneficial effect who reaches: 1, this conversion node structure is succinct, the appearance is graceful, area is little, it is clear and definite to pass power, is applicable to urban transmission line engineering, 2, compare with traditional single tube steel pipe pole, the the stiffness who uses the novel steel pipe tower of this node is great, can effectively reduce the top of the tower displacement, also can reduce the engineering volume on iron tower and basis, reaches the sparingly purpose of resource, 3, compare with four tubs of traditional steel pipe poles, use the novel steel pipe tower of this node and comparatively save steel, have better economic benefits.
Description
Technical field
The utility model relates to a kind of narrow base steel pipe pole four and manages-single tube switching node, belongs to power transmission and transformation line link technique field.
Background technology
In recent years, due to urban construction high speed development, power load increased sharply, and supply network can not meet the needs of power load development, newly-built high pressure certainly will be wanted to go down town circuit, carry out capacity-increasing transformation to netting twine road, original city.Adopt the taper shape steel tube bar of annular or polygonal cross-section, structure is simple, stressed clear, and processing and manufacturing is easy, and easy construction, safe and reliable to operation, maintenance workload is few.
Along with improving constantly of transmission line of electricity transmission line capability and electric pressure, common-tower double-return and multi circuit transmission lines have become inevitable trend in developed area.And the requirement of developed area to line corridor is more and more harsher, place is more and more less, line corridor is more and more narrower and small, and stressed the differing of single pole meets the demand of tower structure design surely, but the cost of multitube steel pipe pole is relatively high.Therefore, develop that tower structure blast is little, rigidity is large, novel steel tube bar or the connected node that can give full play to two kinds of tower advantages are more and more urgent.For the king-sized multiloop angle tower of load, adopt the steel tube tower of single pole or dual rod type formula, because rod member root bending moment is large, cause predominant tube diameter larger, stock utilization is low, even there is the problems such as processing difficulties, so the Novel rod tower structure form that exploitation is applicable to urban area multiple loop transmission line is very necessary.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide single tube-four pipe switching node be applicable in power transmission and transformation line engineering that a kind of integral rigidity is comparatively large, stability better can reduce again steel pipe pole cost simultaneously to a certain extent.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of narrow base steel pipe pole four manages-single tube switching node, for connecting single tube steel pipe pole and four pipe steel pipe poles in power transmission and transformation line, it is characterized in that, comprising upper link block, main body and the lower link block of welding successively; Described lower link block is provided with four, is evenly distributed on the bottom of main body respectively.
The narrow base steel pipe pole four of aforesaid one manages-single tube switching node, it is characterized in that, the end of described upper link block and lower link block is provided with flange.
The narrow base steel pipe pole four of aforesaid one manages-single tube switching node, it is characterized in that, the welding position of described upper link block, main body and lower link block is all welded with stiffening rib.
The beneficial effect that the utility model reaches: 1, this switching node is simple for structure, profile is graceful, floor space is little, power transmission is clear and definite, is applicable to city work transmission line; 2, compared with traditional single tube steel pipe pole, the integral rigidity applying the novel steel tube tower of this node is comparatively large, can effectively reduce tower top displacement, also can reduce the engineering quantity on steel tower and basis, reach the object of saving resource; 3, compared with four traditional pipe steel pipe poles, the novel steel tube tower applying this node comparatively saves steel, has good economic benefit.

The implication of Reference numeral in figure:
1-single tube steel pipe pole, 2-switching node, 3-tetra-pipe steel pipe pole, 4-flange, the upper link block of 5-, link block under 6-, 7-main body.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
The narrow base steel pipe pole four of the one that the utility model relates to manages-single tube switching node 2, for connecting single tube steel pipe pole 1 and four pipe steel pipe poles 3 in power transmission and transformation line.
Switching node 2 comprises upper link block 5, main body 7 and the lower link block 6 of welding successively, and lower link block 6 is provided with four, is evenly distributed on the bottom of main body 7 respectively.
The end of upper link block 5 and lower link block 6 is provided with flange 4, is respectively used to connect single tube steel pipe pole 1 and four pipe steel pipe poles 3.
The welding position of upper link block 5, main body 7 and lower link block 6 is all welded with stiffening rib.
Time assembled at the construction field (site), adopt the scheme that segmentation is from bottom to top lifted by crane, after bottom four pipe steel pipe pole 3 installs, this switching node 2 is arranged on steel pipe pole first cross-arm, node top and single tube bar adopt flange 4 to be connected, and the bottom of node is same with four pipe steel pipe poles 3 adopts flange 4 to connect.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
