Variable-angle unequal-length diagonal box girder bridge erecting machine and bridge erecting method thereof
The invention discloses a variable-angle unequal-length diagonal box girder bridge erecting machine and a bridge erecting method thereof. The bridge erecting machine comprises two main girders arranged in parallel, front and rear supporting leg assemblies arranged at the front and rear ends of the main girders, a main supporting wheel assembly and an auxiliary supporting wheel assembly arranged in the middle of the main girders, a walking mechanism and a hoisting mechanism. A main beam pull rod which is detachably connected is arranged between the two main beams; the front supporting leg assembly and the rear supporting leg assembly are arranged telescopically. The walking mechanism comprises a front supporting walking wheel box arranged at the lower end of the front supporting leg assembly and a main supporting walking wheel box arranged at the lower end of the main supporting wheel assembly. The posture of the bridge erecting machine is adjusted through the main beam pull rod detachably connected with the main beam, the front supporting leg assembly and the rear supporting leg assembly which are detachably connected and transversely restrained, the main supporting wheel assembly and the walking mechanism arranged on the front supporting leg assembly and the main supporting wheel assembly, so that the posture of the bridge erecting machine is matched with the angle of the front cover beam; therefore, the erection of the variable-angle unequal-length diagonal box girder is realized.
本发明公开了一种变角度不等长斜交箱梁架桥机及其架桥方法，架桥机包括平行设置的两根主梁，设置在主梁前后端的前、后支腿总成，设置在主梁中部的主托轮总成和副托轮总成，行走机构和起吊机构。两主梁之间设置可拆卸连接的主梁拉杆；前、后支腿总成伸缩设置；行走机构包括分别设置前支腿总成和主托轮总成下端的前支行走轮箱和下端的主托行走轮箱。本发明，通过与主梁可拆卸连接的主梁拉杆、具有可拆卸连接的横向约束的前、后支腿总成、主托轮总成以及设置在前支腿和主托轮总成上的行走机构，进行架桥机姿态的调整，使架桥机姿态与前盖梁的角度相适配，从而实现变角度不等长斜交箱梁的架设。
