The utility model discloses an atress is at design stage through checking computations, safe and reliable.
Description
Technical field
The utility model relates to a kind of angle tower for line level crossing, particularly a kind of double loop angle tower without crossing frame line level crossing.
Background technology
At present, along with the fast development of South China's urbanization, the situation that newly-built aerial power transmission line crosses over the critical facilitys such as municipal elevated roads, speedway, railway and power circuit is more and more difficult to avoid.The leap unwrapping wire that aerial power transmission line is conventional mainly contains crossing frame line level crossing and without crossing frame line level crossing two kinds of modes.Crossing frame line level crossing is had to be that crossing frame is set and capping net carries out line level crossing, as metal construction crossing frame, little steel pipe crossing frame etc.The crossing frame of this method is simple to operate, also more easily construction safety is ensured, therefore have in various electric pressure line crossing payingoff construction and apply more widely, but be subject to the restriction of orographic condition, and often will face the situation such as compensation negotiation and expense increase that crossing frame takes up an area temporarily.Be utilize shaft tower to support and capping net carries out line level crossing without crossing frame line level crossing, without the need to organizing vertical crossing frame, can avoid the restriction of orographic condition, the situations such as the compensation negotiation that crossing frame also can be avoided temporarily to take up an area and expense increase, the scope of application is also wider.Without crossing frame line level crossing, have and reduce stringing risk, improve the advantages such as efficiency of construction.But without crossing frame line level crossing mainly through crossbeam as bracing or strutting arrangement, the connected mode of crossbeam and steel tower easily offsets, and there is certain construction safety hidden danger.Above two kinds of equal Shortcomings of construction method, and the measure in reserved maintenance situation cannot be considered when building.
Utility model content
For solving the problem, the purpose of this utility model is that providing a kind of gets over the double loop angle tower without crossing frame line level crossing of frame as bracing or strutting arrangement using steel tower cross-arm.
The technical scheme that the invention for solving the technical problem adopts is: a kind of double loop angle tower without crossing frame line level crossing, comprise tower body, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame, the structure that tower body, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame three are integrated, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame are connected to the left and right sides of tower body symmetrically.Stressed process in the design stage of the present utility model checks, safe and reliable.
Further, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame detain the capping net hung with for forming safety net above leap thing.Safety net is formed above leap thing, can effectively avoid Poling Construction process to cause wire directly to fall to leap thing because of the error such as artificial origin's false touch fly block, bracing wire, earth anchor, at utmost reduce crossing construction on cross over facility normal condition impact prerequisite under ensure that construction safety.
Further, tower body, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame are assembled by prefabricated component, the utility model is resolved into prefabricated component, assembles when needed again, be conducive to production of the present utility model, transport and storage.
Further, tower body, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame structure adopt multiple triangular structure, increases anti-pressure ability of the present utility model, improve stability.
Further, tower body is up-small and down-big structure, by decentralization of the present utility model, is conducive to improving stability of the present utility model.
The beneficial effects of the utility model are: a kind of double loop angle tower without crossing frame line level crossing that the utility model adopts, comprise tower body, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame, the structure that tower body, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame three are integrated, side, exterior angle lower wire cross-arm crossing frame and interior angle side lower wire cross-arm crossing frame are connected to the left and right sides of tower body symmetrically.The utility model overcomes traditional connected mode without crossing frame line level crossing middle cross beam and steel tower and easily offsets, and there is the shortcoming of construction safety hidden danger.Stressed process in the design stage of the present utility model checks, safe and reliable.
