The invention relates to the technical field of bridge cranes, and discloses a single-beam bridge crane which comprises a main beam, a sliding way is formed in the outer surface of the upper end of the main beam, a fixing frame is slidably connected to the outer surface of the upper end of the main beam, and sliding grooves are formed in the positions, close to the lower end, of the outer surfaces of the two sides of the main beam. A main shaft is rotatably connected to the position, close to the lower end, in the fixing frame, a steel rope is slidably connected to the outer surface of the main shaft, a right motor is fixedly connected to the outer surface of the upper end of the fixing frame, a rotating shaft is rotatably connected to the lower end of the motor, an inner cavity is formed in the fixing frame, and a first gear is fixedly connected to the lower end of the rotating shaft. The single-beam bridge crane has the advantages of avoiding rail gnawing and derailing, guaranteeing stable operation of the crane, avoiding falling of the suspension type crane due to deflection of the cross beam and the like, and solves the problems of rail gnawing and derailing of two sides of the crane and falling of the suspension type crane due to deflection of the cross beam.
本发明涉及桥式起重机技术领域,且公开了一种单梁桥式起重机,包括主梁,所述主梁的上端外表面开设有滑道,所述主梁的上端外表面滑动连接有固定架,所述主梁的两侧外表面靠近下端的位置均开设有滑槽,所述固定架的内部靠近下端的位置转动连接有主轴,所述主轴的外表面滑动连接有钢绳,所述固定架的上端外表面固定连接右电机,所述电机的下端转动连接有转轴,所述固定架的内部开设有内腔,所述转轴的下端固定连接有第一齿轮。该单梁桥式起重机,具备避免出现啃轨脱轨,保障起重机运行平稳、避免了悬挂式吊机因横梁歪斜掉落等优点,解决了起重机两侧因啃轨、脱轨,以及悬挂式吊机因横梁歪斜掉落的问题。
