Description

European crane trolley buffering protection device Technical Field The utility model relates to the technical field of crane devices, in particular to a buffer protection device for an European crane trolley. Background The European crane has the characteristics of light dead weight, small structure and low energy consumption. The trolley and the lifting mechanism are arranged on the bridge, and the trolley runs back and forth along the rail beam of the bridge, so that the material objects are carried in a three-dimensional space. The European crane adopts a unique design concept and has the characteristics of small size, light weight and small wheel pressure. Compared with the traditional crane, the overhead height is lowest, the lifting height is higher, the effective working space of the existing factory building is actually increased, and the crane is widely applied to factory buildings and warehouses. When the existing European crane trolley walks along the rail beam, the existing European crane trolley tends to continue to slide for a certain distance due to inertia when the existing European crane trolley walks to the limiting end to brake. So the buffer protection device is usually installed at the limit end of the rail beam. Traditional buffer is mostly elastic collision buffer, relies on the buffer to strike spacing end after promptly, produces resilience force through deformation, realizes the impact buffering. However, the buffer piece can generate certain rebound after the trolley moves to the limiting end to compress the buffer piece, namely, the European crane trolley can reversely rebound for certain displacement after the limiting end brakes, so that the violent swing of the lifting hook is caused, and potential safety hazards are easily caused.
