Abstract

The invention relates to the technical field of excavation, and discloses a hob driving adjustment and overload protection system for excavation. The hob driving adjustment and overload protection system comprises a supporting plate, and a notch is formed in the supporting plate. A cylinder body is arranged in the supporting plate, and a push rod is arranged in the cylinder body. A power device isarranged on the surface of the supporting plate, and a hydraulic system is arranged on the surface of the supporting plate. A driving machine is arranged on the side face of the supporting plate, anda rotating shaft is arranged on the surface of the driving machine. A main gear is arranged on the surface of the rotating shaft, and a rotating rod is movably connected to the surface of the rotating shaft. According to the hob driving adjustment and overload protection system for excavation, through cooperative use of an induction magnet, a torque sensor and an electromagnet and cooperative useof a driving shaft and a bump, when the torque borne by a hob is too large, the bump can be rapidly disengaged from the driving shaft, so that the hob is disengaged from the driving shaft, thereforedriving overload of a machine is prevented, and the operation safety of mechanical equipment is protected.

Description

technical field [0001] The invention relates to the technical field of excavation, in particular to a drive adjustment and overload protection system for an excavation hob. Background technique [0002] Excavation refers to the excavation of part of the soil and rock volume from the original ground to the surface of the roadbed when the surface of the roadbed is lower than the original ground. When excavating the surface of the roadbed, some excavating machinery and equipment will be involved, one of which is to cut the roadbed with a hob. The excavation operation is carried out on the surface to loosen the roadbed to facilitate the subsequent transportation of soil and rocks on the roadbed surface. [0003] The existing hob working method is to form a hob group by several hobs, which are driven by the same drive shaft, and the hob groups work synchronously. When the resistance of one of the hobs increases, the other hobs The operating efficiency will also be reduced, resul...
