The invention discloses a safety braking double-beam crane. The safety braking double-beam crane comprises an end beam, wherein a traveling wheel is rotatably connected to the inner side of the end beam; a first main beam is fixedly connected to the right end of the upper surface of the end beam through bolts; a second motor is fixedly connected to the right side of a winding box through bolts; asteel wire rope winds a winding column; an electric telescopic rod is fixedly connected to the middle of the upper surface of a box body; a brake plate is hinged to the inner side of the lower end ofthe box body; a connecting plate is hinged to one side, away from a rotating shaft, of the brake plate; a pressing plate is fixedly connected to the upper end of the connecting rod through bolts; anda brake pad is arranged on one side, close to the rotating shaft, of the brake plate. The safety braking double-beam crane is convenient for safety braking on a hoisting device to prevent materials from falling out of control and effectively reduce the threats to security; and in addition, the hoisting device can be moved more stably and smoothly, and therefore the practicability of the double-beam crane is effectively improved.
Description
Technical field [0001] The invention relates to the technical field of cranes, in particular to a double-beam crane with safety braking. Background technique [0002] The working characteristic of the crane is to do intermittent movement, which is mainly used for the lifting and loading and unloading of materials. The double-beam crane is one of many types of cranes. It is composed of two main beams and a lifting mechanism. Workshops, stock yards, warehouses and other places are widely used. Compared with single-beam cranes, the lifting height of double-beam cranes must be higher than the height of a beam section for cranes of the same height. The lifting capacity is much heavier than the single beam crane, and the working level is higher, but the existing double beam crane still has some defects, such as: [0003] 1. When the lifting device fails during work, it is inconvenient to brake the lifting device safely, which will easily cause the winding device to fail and cause the ma...
