Technical Field
The invention relates to the technical field of heavy lifting beams of underground coal mine diesel monorail crane systems, in particular to a device for enabling a lifting beam to pass through a curve.
Background
The heavy lifting beam of the diesel engine monorail crane is mainly responsible for transporting a hydraulic support, and the hydraulic support belongs to heavy equipment, is dozens of tons at all times, is irregular in appearance and large in size. The underground roadway is uneven in height and numerous in bent ways, so that the lifting capacity of the transportation equipment and the up-down slope and bend-passing capacity of the transportation equipment are tested during underground transportation of the hydraulic support. The hydraulic support is about 5-10 meters in length, the heavy lifting beam is about 10-14 meters in length, and the underground turning radius is about 4 meters, in which case the ability of the diesel monorail to lift the heavy lifting beam through a bend becomes especially important. Otherwise, once the equipment is clamped at the bent part, the hydraulic support is inclined and tilted backwards under the action of inertia force, and serious safety accidents can happen when the inclined or tilted backwards angle is too large, so that the problem of not processing the bent part is not only a potential safety hazard, but also the transportation efficiency is influenced.
However, the existing hydraulic support has a length of about 5-10 meters, the heavy lifting beam has a length of about 10-14 meters, and the underground turning radius is about 4 meters, and in this case, the capability of the diesel monorail to lift the heavy lifting beam through the curve becomes more important. Otherwise, once the equipment is clamped at the bend, the hydraulic support is inclined and tilted backwards under the action of inertia force, and serious safety accidents can happen when the inclined or tilted backwards angle is too large, so that the problem of not processing the bend is a potential safety hazard and influences the transportation efficiency; thus, the existing requirements are not met, and a device for enabling the lifting beam to pass through the curve is provided.
