Deck crane and front walking supporting mechanism thereof
The invention provides a bridge deck crane and a front walking supporting mechanism thereof, the front walking holding mechanism is arranged at the front end of a rear pressing rod of a supporting truss and comprises a front walking mechanism and the front supporting mechanism, the front walking mechanism comprises a walking track, a walking joint and a push-pull oil cylinder, and the walking joint is fixed at the front end of the rear pressing rod; the walking rail is also connected with the rear pressing rod and can slide relative to the rear pressing rod, the walking connector is matched with the walking rail and can slide relative to the walking rail, the push-pull oil cylinder is arranged between the walking connector and the walking rail, a cylinder barrel of the push-pull oil cylinder is fixed to the walking rail, and the extending end of a piston rod of the push-pull oil cylinder is connected with the walking connector; the front supporting mechanism comprises a supporting oil cylinder. Self-walking of the bridge deck crane is achieved through cooperation of the front walking mechanism and the front supporting mechanism, re-dismounting is not needed, the structure is convenient, the front supporting mechanism is used for supporting in the hoisting box girder, the bridge deck crane is prevented from sliding, and the stability of the hoisting process is improved.
本申请提供一种桥面吊机及其前行走支撑机构，其中，所述前行走持恒机构设于支撑桁架的后压杆前端，包括前行走机构及前支撑机构，前行走机构包括行走轨道、行走接头及推拉油缸，行走接头固定于后压杆的前端，行走轨道亦与后压杆连接并可相对后压杆滑动，行走接头与行走轨道配合且行走接头可相对行走轨道滑动，推拉油缸设于行走接头与行走轨道之间，推拉油缸的缸筒与行走轨道固定，推拉油缸的活塞杆伸出端与行走接头连接；前支撑机构包括支撑油缸。通过前行走机构与前支撑机构的配合实现桥面吊机的自行走，无需重新拆装，结构方便，利用前支撑机构在吊装箱梁中支撑，避免桥面吊机滑动，提高吊装过程的稳定性。
