Crossbeam 50 is fixed on truss.By adjusting compensation screw rod 51 height, adjustable compensation work line it is sagging.
The path of every active line are as follows: by spooler, successively pass through two support frames in head portion, in head portion
Work coil holder, three work coil holders on tilting section and two work coil holders in head portion, finally by active line the end of a thread
It hooks on the big angle steel of head portion, reversion spooler tightens active line.
Two support frames in head portion are also used for support active line for being fixed temporarily tensioning frame.
The walking path of every active line detour up and down in vertical plane, successively around two support frames in head portion and
The top of work coil holder then passes around the lower section of three work coil holders on tilting section, finally around two work in head portion
The top of coil holder.It is connect with respect to active line and the crossbeam on work coil holder and support frame with chord member above and below described herein
For contact portion position, i.e. the active line either above or below that is located at contact site.
(4) truss is horizontal and straightness corrects, and is detected using infrared transmitting device to tilting section chord member straightness
And the sag of chain of active line is compensated.
As shown in fig. 4 a, infrared detector is installed in the upper left chord member upper and lower ends of truss tilting section, detector includes point
It is not mounted on the RF transmitter of the upper end C of truss tilting section and is mounted on the test board of lower end A, test board bottom has
The pedestal being fixedly mounted with truss, when pedestal is fixed on truss, tilting section of the test board perpendicular to truss.

It is equidistant at the upper end C and lower end A of tilting section with truss.
First by truss upper left chord member and upper right chord member level-off before detecting tilting section chord member straightness, such as Fig. 4 a institute
Show, integration it is main drive side plate overcentre I at support frame and tensioning frame above I at 1 support frame crossbeam 16 on
Level meter is placed, adjusts the jacking block of truss head supporting frame 79 just by the left chord member and right chord member water of the section of leveling up and down of truss
Pingdu is adjusted to process set value.Level meter is placed on middle part work coil holder crossbeam 50 at B, is adjusted at left and right sides of truss
The mandril height of truss intermediate support beam 80 keeps left and right chord member at B horizontal.
At the middle part of truss, distance of the measurement infrared ray apart from truss, distance of the infrared ray apart from upper left chord member upper surface are anti-
Answered the straightness (i.e. chord member is sagging or the size of arch) projected on vertical plane, infrared ray apart from upper left chord member side away from
From having reacted the straightness projected in the horizontal plane.
The distance measured is compared with the equidistant value that the both ends A, C are set and obtains a difference, the difference is if more than work
The limiting value of skill setting then needs the mandril height for readjusting truss intermediate support beam 80, until difference is less than process set value,
Need to guarantee that left and right chord member is horizontal simultaneously, after being adjusted optimally, by chord member there is also straightness error be recorded on chord member,
Only left side chord member can detect and record to improve efficiency.
According to the error amount that above-mentioned steps obtain, calculate active line in the middle part of tilting section apart from upper left chord member it is theoretical away from
From, adjustment mandril is hung into the depth of pedestal, to adjust the height and position of middle part work coil holder, to the sag of chain in the middle part of active line into
Row compensation, the lifting distance of compensation screw rod 51 are equal to upper left chord member and project difference (paying attention to positive and negative values) on vertical plane
