The invention relates to the technical field of cranes, in particular to a crane with a cross beam provided with a locking device. The crane comprises the cross beam, the cross beam is provided with aguide rail, a traveling crane is slidably mounted in the guide rail, an electric hoist is fixedly mounted on the traveling crane, the cross beam is provided with a cross groove, a locking plate is fixedly mounted in the cross groove, and a clamping groove is formed in the locking plate; and a side bracket is fixedly mounted on the traveling crane, a driving gear and a driven gear are rotatably mounted in the side bracket, cranks are fixedly mounted on gear shafts of the driving gear and the driven gear, and a first connecting rod and a second connecting rod are rotatably mounted on the cranks. The cross beam is provided with the cross groove with the locking plate, clamps are mounted on the two sides of the traveling crane on the cross beam through the side support, the two clamps move inwards at the same time to be clamped on the locking plate, generated force has a locking effect on the traveling crane, it is guaranteed that a heavy object is safely and stably lifted through the electric hoist, and accidents are effectively avoided.

    本发明涉及起重机技术领域,具体为一种横梁带有锁定装置的起重机,包括横梁,所述横梁设置有导轨,且导轨中滑动安装有行车,且行车上固定安装有电动葫芦,所述横梁上设置有横槽,且横槽中固定安装有锁定板,且锁定板上设置有卡槽,所述行车上固定安装有侧支架,且侧支架中转动安装有主动齿轮和从动齿轮,所述主动齿轮以及从动齿轮的轮轴上均固定安装有曲柄,且曲柄上转动安装有第一连杆和第二连杆;在横梁上设置有带锁定板的横槽,而横梁上的行车两侧通过侧支架安装有夹钳,通过两个夹钳同时内移夹紧在锁定板,产生的力对行车起到了锁定作用,保证重物通过电动葫芦提升的安全稳定,有效的避免了事故的发生。
