Description

Anti-falling bridge crane

Technical Field

The utility model relates to a bridge crane technical field specifically is a prevent bridge crane that falls.

Background

A crane is a hoisting machine used to lift goods vertically and move them horizontally over a small distance. In industry, a large number of cranes are used in a wide variety of configurations, applications and cargo moving methods. The most common bridge cranes used for moving goods in three mutually perpendicular directions in workshops and warehouses. According to the types of the transported goods, the crane is provided with different types of fetching devices, namely a lifting hook and a lifting electromagnet. The most commonly encountered are bridge hook cranes, which carry goods that are tied up by chains or ropes and hung from the hook of the crane. The bridge crane consists of two main parts, a bridge frame and a trolley. The bridge of a crane is a metal structure supported on wheels driven by a bridge running mechanism. The running mechanism is directly installed on the bridge frame, and enables the crane to horizontally move along the steel rail laid on the crane walking beam along the workshop. The trolley of the crane consists of a frame supported on wheels, a lifting mechanism and a running mechanism. The hoisting mechanism is used to hoist the goods vertically, while the running mechanism is used to move the goods horizontally along the crane bridge, i.e. laterally along the workshop. The three hoisting mechanisms, trolley travelling mechanism and bridge travelling mechanism of the bridge crane are each provided with a separate motor, and the three mechanisms are driven independently of each other.

At present, the hoist rope cable of current bridge crane is the main atress part of hoist, consequently can take place certain wearing and tearing or ageing after using for a long time again, and wearing and tearing are difficult to in time discover, consequently the in-process rope cable that lifts by crane breaks and is led to by a wide margin the goods probability of falling of being lifted by crane increases, cause certain threat to the environment of lifting by crane, influence the safety of work of lifting by crane, and because the error that the production assembly caused and the wearing and tearing that the later stage use led to the fact, can directly lead to hoist walking dolly to take place the skew to gnaw the condition of rail or even derail at the in-process of walking, there is certain potential safety hazard.
