Abstract

The invention discloses an electric hoist crossing safety mechanism during combined operation of multiple cranes. The butt joint of main beams of two cranes is provided with a safety protection mechanism capable of enabling an electric hoist trolley to cross the main beam of one crane to the main beam of the other crane, a mandrel support is fixed on a bottom frame, an electric push rod is fixed with the crane through the mandrel support, a hole at the front end of the electric push rod is connected with one end of a connecting shaft, the other end of the connecting shaft is welded to a driving baffle, the driving baffle and the other driving baffle are connected through a shaft and are symmetrically fixed on the tail end of the main beam of the crane, and one driven baffle and the other driven baffle are connected through the other shaft and are symmetrically fixed on the head end of the main beam of the other crane. The electric hoist can work on one crane or another crane, the driving baffle and the driven baffle can play a role in stopping, and the electric hoist can not be driven out of the crane due to misoperation.

Description

technical field [0001] The invention relates to an over-span safety mechanism, which is especially suitable for protecting the running process of an electric hoist trolley when a plurality of cranes work together, so that the phenomenon of electric hoist falling will not occur. Background technique [0002] Under certain conditions, multiple cranes are required to work together. The electric hoist used as a lifting mechanism needs to be hoisted and operated across the span, and it is moving to transport items between the two workshops. The safe operation of the electric hoist across the span is particularly important. [0003] In the previous design of this type of crane group, similar stoppers may be provided, but the operation is cumbersome and the design cost is high, or similar stoppers are not provided, which reduces the function of the cranes. [0004] The application number 201810119965.0 published by the National Patent Office is titled "Multi-Crane Coordinated Lifti...
