The invention provides a segmental beam lifting appliance. The segmental beam lifting appliance comprises a lifting rod, a leveling frame and a bearing beam, wherein the leveling frame is arranged below the suspender, the top end of the leveling frame is connected with the suspender, the bottom end of the leveling frame is pivoted with the bearing beam, and a plurality of hanging brackets are further arranged on the bearing beam. The lifting rod is connected with a crane lifting hook so as to realize integral lifting of the lifting appliance; by means of the bearing beam pivoted to the bottom end of the leveling frame, the bearing beam can swing around the bottom end of the leveling frame, then the inclination angle of the bearing beam is adjusted so as to drive the inclination angle of the segmental beam, the gravity center value of the segmental beam can be adjusted under the bearing beam, swing of the segmental beam in the hoisting process is avoided, and after hoisting is in place, the segmental beam can be lifted in place. The inclination angle of the segmental beam is adjusted to be matched with the inclination angle of installation arrangement, so that installation of the segmental beam is facilitated, stability in the hoisting process is improved, the swing amplitude of the bearing beam is reduced, the height difference of the two sides of the segmental beam is adjusted, and it is guaranteed that the segmental beam is accurately in place.

    本发明提供了一种节段梁吊具,该节段梁吊具包括:吊杆、调平架和承重梁;其中,调平架设置在吊杆的下方,调平架的顶端与吊杆相连接,底端与承重梁相枢接,承重梁上还设有若干个吊架。本发明通过吊杆连接吊车吊钩,以实现该吊具的整体吊装;通过枢接在调平架的底端的承重梁,以使承重梁可以绕调平架的底端进行摆动,进而调整承重梁的倾斜角度,以带动节段梁的倾斜角度,使得节段梁可调整重心值承重梁的正下方,避免节段梁吊装过程中的摆动,还可在吊装到位后,调整节段梁的倾斜角度至与安装布置的倾斜角度相适配,进而便于节段梁的安装,提高了起吊过程中平稳性,减小承重梁摆动幅度,调整节段梁两侧高差,保证节段梁准确就位。
