Big section door shape steel work pole
Technical field
The invention belongs to power domain, relate to the upright used pole of iron tower of group of UHV transmission line construction, especially a kind of big section door shape steel work pole.
Background technology
The stayed tower of extra-high voltage (V-type, a door shape) group cube formula has nothing in common with each other both at home and abroad at present, send the history of five more than ten years of power transformation industry and the accumulation of construction experience and the group tower mode of the constituent parts that precipitation makes to have nothing in common with each other, but generally speaking at group power Guywire tower nothing more than several forms such as formula herringbone pole group is upright, split lifting, integral hoisting that have integral body to fall.On the basis of these several lifting forms, need use respectively according to actual conditions, be subjected to the restriction of complex-terrain simultaneously, Zu Zhuan quilt plays the place that tower crane spare can only be assembled in permission sometimes.For example, in the 750KV interconnection engineering of Qinghai-Tibet, the integral body upright engineering of formula herringbone pole group that falls bans use of, and can only adopt split lifting or integral hoisting.
Lifting capacity is big, lifting is unstable, cost is higher, the defective of easy deformation but integral hoisting exists, moreover for most lifting situation, the split lifting is main means.And existing split lifting exists lifting inefficiency, more, the dangerous higher shortcoming of work high above the ground.
By retrieval, do not find publication document related with the present patent application as yet.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of and lift the efficient height, lifting is safe and reliable big
Section door shape steel work pole.
The present invention solves its technical problem and is achieved through the following technical solutions:
A kind of big section door shape steel work pole, hypomere, standard paragraphs, beam segments, epimere and the pedestal, lifting tackles, corner block, suspender, the pull rope that comprise steel work, the hypomere of steel work, standard paragraphs, beam segments, epimere connect as one the formation principal post from bottom to top, the door shape steel structure frame form that two parallel principal posts of described pole and crossbeam constitute, common hinge dress crossbeam between the beam segments of two principal posts, hinge is adorned a brace summer on the top of two principal posts, and the bottom hinge of hypomere is contained on the pedestal.
And, the parallel pull bar that crosses the river that is equipped with between the principal post of crossbeam lower end.
And, in the principal post both sides of corresponding each draw rod positions that crosses the river, the principal post both sides of beam segments, the principal post both sides of brace summer a pair of lateral conductor is installed all.
And, at crossbeam and both sides principal post upper end two diagonal members are installed.
And described brace summer is a seamless steel pipe.
Advantage of the present invention and beneficial effect are:
1, the present invention adopts a shape steel structural form, two principal post tops are provided with crossbeam and steel pipe brace summer, the three roads pull bar that crosses the river also is set between two principal posts, former and later two are set on crossbeam play sling point, be hinged between crossbeam, brace summer and the principal post, the bottom of principal post is a free bearing, and the hinge of two positions dress has overcome two principal posts because the problem of immerge discrepancy in elevation when the basic discrepancy in elevation and lifting.Overall construction design is scientific and reasonable, can realize the principal post integral hoisting of Guywire tower and the integral hoisting of crossbeam fully.
2, the scope of application of the present invention is wide, is subjected to the restriction of MODEL OVER COMPLEX TOPOGRAPHY less, can be generalized to the lifting of wind power generating set, can effectively solve the problem that large-scale hanging device can't enter the wind-power electricity generation building site.
Description of drawings
Fig. 1 is a structural front view of the present invention.
The specific embodiment
The invention will be further described below by specific embodiment, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
A kind of big section door shape steel work pole, hypomere 10, standard paragraphs 8, beam segments 6, epimere 3 and the pedestal 11, lifting tackles 16, corner block 15, suspender 12, the pull rope 14 that comprise steel work, the hypomere of steel work, standard paragraphs, beam segments, epimere connect as one the formation principal post from bottom to top, this pole is the door shape steel structure frame form that two parallel principal posts and crossbeam constitute, adopt hinge plate 5 common hinge dress crossbeams 4 between the beam segments of two principal posts, hinge is adorned a brace summer 1 on the top of two principal posts, and this brace summer is a seamless steel pipe; The bottom hinge of hypomere is contained on the pedestal.
(can according to the actual conditions desired location) installs lifting tackles at a certain position of the hypomere of crossbeam, this lifting tackles is by suspender lifting iron tower parts, the power resources of this assembly pulley are in the pull rope through corner block, and this pull rope is connected with winch or other pulling equipment; Lifting tackles is two of front and back, and the present embodiment accompanying drawing only demonstrates one, and another is in its back.
Principal post of the present invention and pedestal, principal post and crossbeam, principal post and brace summer are hinge dress form, thus, can realize not being subjected to the place restriction and at the lifting operation of certain angle.In order to stablize total, the parallel pull bar 9 that crosses the river that is equipped with in the present embodiment accompanying drawing is three between the principal post of crossbeam lower end.
In order to stablize total, a pair of lateral conductor 7 all is installed in the principal post both sides of corresponding each draw rod positions that crosses the river, the principal post both sides of beam segments, the principal post both sides of brace summer.
In order to keep the intensity of crossbeam, two diagonal members 2 also are installed at crossbeam and both sides principal post upper end.
Instantiation of the present invention:
59.6 meters of pole principal post length, section are 1000*1000mm, and main material is Q345, and auxilliary material is q235.
The crossbeam length of pole is 5.8 meters, and section is 1000*1000mm, and main material is Q345, and auxilliary material is q235.
The seamless steel pipe of brace summer diameter 120*5,6.3 meters of total lengths.
The crossbeam height is 55 meters, is provided with the three roads pull bar that crosses the river between two principal posts.
