Bridge deck crane
The invention provides a bridge deck crane which comprises a supporting truss, a lifting mechanism and a walking mechanism, the supporting truss comprises a bearing main beam, a stand column, an inclined strut, a rear pressing rod and a rear pull rod, the bearing main beam and the rear pressing rod extend in the horizontal direction, and the stand column is perpendicularly connected between the bearing main beam and the rear pressing rod; the inclined strut is connected with the bearing main beam and the upright post to form a first triangular truss; the rear pull rod is connected with the upright post and the end part of the rear pressing rod to form a second triangular truss; the lifting mechanism is arranged on the bearing main beam and can slide relative to the bearing main beam; the walking mechanism is arranged at the bottom of the rear pressing rod, a front supporting mechanism is arranged at the front end, close to the stand column, of the rear pressing rod, and the rear pressing rod is provided with a rear anchoring mechanism fixed to the bridge deck. A truss structure is formed by the bearing main beams, the stand columns, the inclined struts, the rear pressing rods and the rear pull rods to serve as a main supporting structure of the bridge deck crane, the stability and the load capacity of the bridge deck crane are enhanced, the structure is simple, operation is convenient, and the hoisting efficiency of the steel box girder is greatly improved.
本申请提供一种桥面吊机，其包括支撑桁架、提升机构及行走机构，支撑桁架包括承重主梁、立柱、斜撑、后压杆及后拉杆，承重主梁及后压杆均沿水平方向延伸，立柱垂直地连接于承重主梁与后压杆之间，斜撑连接承重主梁及立柱以构成第一三角桁架，后拉杆连接立柱及后压杆的端部以构成第二三角桁架；提升机构设于承重主梁上并可相对承重主梁滑动；行走机构设于后压杆的底部，后压杆靠近立柱的前端设有前支撑机构，后压杆设有与桥面板固定的后锚机构。通过承重主梁、立柱、斜撑、后压杆及后拉杆构成桁架结构以作为桥面吊机的主要支撑结构，增强桥面吊机的稳定性和荷载能力，结构简单，操作方便，极大提高了钢箱梁的吊装效率。
