The specific embodiment
As shown in Fig. 1-6, described in the utility model embodiment can automatic deviation correction incremental launching construction guiding carriage, comprise sliding way and glide path, described sliding way bottom is provided with sliding way base plate 4, sliding way both sides are longitudinally provided with vertical sliding way limit web 1, sliding way center is longitudinally provided with vertical sliding way median ventral plate 2, and sliding way inner transverse is provided with some vertical upper runway transverse dividing plates 3, described glide path top is provided with glide path top board 5, glide path both sides are longitudinally provided with vertical glide path limit web 6, glide path bottom is provided with the glide path base plate 7 of level, glide path center is longitudinally provided with vertical glide path median ventral plate 11, glide path median ventral plate 11 both sides are longitudinally provided with the longitudinal stiffener 9 of vertical glide path, between the longitudinal stiffener 9 of glide path and described glide path limit web 6, be laterally provided with some vertical glide path outer container chamber diaphragms 8, between the longitudinal stiffener 9 of glide path and described glide path median ventral plate 11, be laterally provided with some vertical glide path inner cabinet diaphragms 10, described sliding way base plate 4 and glide path top board 5 are in the shape of the letter V, between sliding way base plate 4 and glide path top board 5, be provided with the slide block 13 of V font, described glide path base plate 7 belows are fixedly connected with distribution beam 12, described sliding way base plate 4 is identical with the level inclination of glide path top board 5 both sides of the edge, the angle of level inclination is more than or equal to 6 ° and be less than or equal to 10 °, described sliding way base plate 4 transverse horizontal length are less than the transverse horizontal length of glide path top board 5, connection between each parts of described sliding way and glide path adopts welding.
During concrete use, according to project situation, by the be correlated with size etc. of plate of calculative determination, then process each plate.
During construction, should first accurately locate the position of upper and lower slideway in vertical jacking direction.Install after distribution beam 12, weld glide path base plate 7 thereon.Then, on glide path base plate 7, complete the welding of glide path inner cabinet diaphragm 10 and glide path median ventral plate 11.According to level inclination α, locate and weld glide path top board 5, then at the longitudinal stiffener 9 of relevant position welding glide path.For the globality of stiffening device, in the longitudinally connecting portion enforcement plug welding of stiffener 9 and glide path inner cabinet diaphragm 10.Finally, welding glide path outer container chamber diaphragm 8 and glide path limit web 6.After completing, the end face of glide path top board 5 should be polished smooth, or soldering stainless steel plate in the above, to reduce friction factor.
