Description
Technical field
Present invention relates particularly to a kind of typical landform tower erection construction equipments.
Background technique
Inner suspended inner guy pole group tower technology, pole have it is light, compact, be conducive to assembling, structure it is simple, convenient for the palm
The features such as holding has been widely used, but there is also construction efficiency it is low, security performance is relatively poor the deficiencies of place.Ground type
The advanced group of high tower technologies of security performances such as flat arm pole group tower technology, ground type rocker pole lifting group tower technology, have peace
The advantages that full performance is high, single lifting hoist is big, lifting is steady, but also have its limitation, exist group tower itself transport,
Assemble, debug, remove it is time-consuming and laborious, and it is costly the deficiencies of place.Therefore, these advanced technologies are only in traffic condition
It is good, under the conditions of orographic condition is good, steel tower weight itself and structure size are big etc., technical economic benefit is just obvious.
Currently, highlands especially Tibet region iron tower of power transmission line vertical construction, execution conditions are more severe (high
Original, High aititude, high and cold, anoxic, long-distance transport is difficult, orographic condition is poor, effective construction time is short etc.), part tower position also in
Cliffs and precipices, steel tower construction will face more challenges.It is embraced under these conditions according to derrick crane group tower technology, double flat arm
The existing advanced group of tower technology such as bar group tower technology, weight of equipment is possibly even near or above steel tower weight, it is clear that some are obtained not
Mistake is repaid, therefore, no matter technically also not ideal from economic aspect.
Currently, highlands especially Tibet region mostly uses inner suspended inner guy pole group tower technology, the technology is because must
Palpus dependence control wind rope, which is pulled outwardly, holds funeral rites part to keep and organize at a distance from vertical iron leg tower, relatively so as to cause security performance
Difference, the shortcomings such as construction efficiency is low.According to the existing pole with boom class, boom, which bears huge and load, to be caused to set
Standby bulky or even weight of equipment may be close to or be more than steel tower weight, and it is larger that difficulty is installed and used in the transport of equipment itself；
Meanwhile this method also needs to prevent hanging piece from shaking using control wind rope, causes construction efficiency low, therefore tower erection is constructed
Safety, duration etc. face huge challenge.
Summary of the invention
