The invention discloses a light-weight double-beam bridge crane, and relates to the technical field of bridge cranes, the light-weight double-beam bridge crane comprises two main beams and two longitudinal rails, a plurality of supporting wheels are fixedly mounted at the front and rear parts of a supporting frame, an alarm is fixedly mounted on the outer surface of a protective shell, and a pressing plate is fixedly mounted on a button of a button switch. Rollers are fixedly installed at the rear ends of the first transmission shafts, transmission belts are installed outside the driven wheels and the driving wheels in a transmission mode, and roller brushes are fixedly installed at the rear ends of the second transmission shafts. The device can give an alarm when the crane carriage just deflects and does not deviate from the guide rail so as to remind on-site workers, so that the workers can shut down the crane carriage in advance, the safety of the on-site hoisting environment is improved, and in the process that the crane carriage moves and walks along the guide rail on the main beam, the safety of the crane carriage is improved. And the roller brush can be driven to rotate to sweep the outer part of the guide rail, so that the normal walking of the crane carriage is ensured, and the later cleaning frequency of maintenance personnel can be reduced.

    本发明公开了一种轻型双梁桥式起重机,涉及桥式起重机技术领域,包括两个主梁以及两个纵向轨道,支撑架的前后部均固定安装有若干个支撑轮,防护壳的外表面固定安装有报警器,按钮式开关的按钮上固定安装有压板,第一传动轴的后端固定安装有滚轮,从动轮与主动轮的外部传动安装有传动带,第二传动轴的后端固定安装有辊刷。本发明可在起重小车刚发生偏转还未偏离导轨时发出警报,以提醒现场的工作人员,使工作人员能够提前将起重小车关停,因此提高现场吊装环境的安全性,而且在起重小车沿着主梁上的导轨移动行走的过程中,可带动辊刷转动来对导轨的外部进行扫刷,保证起重小车正常行走的同时,又可降低维护人员后期的清洁频率。
