Description
Technical field
The invention belongs to overhead transmission line iron tower vertical construction equipment field, be specifically related to a kind of guide track system that is used to go straight up to the upright iron tower of power transmission line cross-arm end of unit.
Background technology
Iron tower of power transmission line is broadly divided into two classes by structure types, i.e. backguy sections tower and self-supporting tower, wherein self-supporting tower, good rigidly more roomy because of turriform, need not advantages such as backguy and obtained extensive use.Self-supporting tower (Fig. 1 is the planar line block diagram of certain type self-supporting tower) is generally by hundreds of and even the thousands of space truss structures that shaped steel is formed by connecting by bolt or rivet, and its cross section is square or rectangle more, and each side is plane frame.Four main rod members of iron tower space truss are called main material, use the abdomen material to connect between adjacent two main materials.Quan Take is divided into multistage, comprises tower leg 11 (first section truss on the basis), body of the tower 12 (being made up of the multistage truss) and tower head 13 3 parts from bottom to top, and wherein the horizontal component of tower head 13 is called as cross-arm 14, and it is generally the square trussed construction of variable cross-section.
It is upright that self-supporting tower generally uses the split tower erection method to organize, and also can whole group stand under the situation of conditions permit.The split tower erection method is that iron tower is split into single, monolithic or single hop, uses that crane gear lifts separately, butt joint in the air, the upright a kind of iron tower assemblage construction method of group according to the order of sequence.Compare group tower crane gears such as normally used construction pole, runabout crane, group tower special tower crane and organize tower, going straight up to the unit tower is the iron tower assemblage construction method of a kind of novelty, uniqueness.Compare other group tower, use is gone straight up to the unit tower and is had the following advantages:
(1) because the tower section is assembled on ground, reduced amount of high-altitude operation, safety is good;
(2) do not need group tower and tower material etc. is transported to iron tower scene in place, alleviated constructor's labour intensity, reduced transport channel simultaneously and opened up and the vegetation felling, protected ecological environment, be particularly suitable for the abominable places of construction environment such as high and steep mountains;
(3) group column efficiency height.
Use is gone straight up to the unit tower segmentation weight of iron tower, joint form, joint location etc. is all had higher requirements, and maximum difficult point is how to guarantee that the tower section is skyborne accurately, automatic butt, avoid manual intervention as far as possible, guarantee construction safety, efficient, so the butt joint of tower section is most important with guide rail.
Because the cross-arm of some self-supporting tower is heavier, will exceed the handling ability of helicopter as integral hoisting, need the cross-arm end is split out lifting separately for this reason.When the upright self-supporting tower cross-arm end of unit was gone straight up in use, general work progress was as follows:
(1) hung the link position place mounting guide rail system 2 of cross-arm end 32 and cross-arm 31 in place;
(2) use suspension arrangement 33 that cross-arm end 32 is suspended on helicopter ventral below, then with its handling to the front upper place of cross-arm 31 in place and hover;
(3) helicopter pilot reduces hover height gradually, and cross-arm end 32 is slowly descended by the guide effect of guide track system 2, and it is in place to enter the installation site, and this moment, guide track system 2 provided interim support for cross-arm end 32;
(4) helicopter unclamp with being connected of cross-arm end after fly away from, constructor Deng Ta uses bolt with junction plate cross-arm end 32 to be connected with cross-arm 31 in place, removes guide track system 2 at last, thereby finishes the helicopter lifting construction of cross-arm end.
