Digging and exploring arm support mechanism

Abstract

The invention discloses an excavating and detecting arm support mechanism. The excavating and detecting arm support mechanism comprises an excavating working mechanism and a detecting device, whereinthe excavating working mechanism at least comprises a large arm and a small arm which are hinged in sequence, an excavator bucket is hinged to the small arm, the large arm, the small arm and the excavator bucket are driven by an oil cylinder, the detecting device is arranged on the large arm or the small arm, the excavation working mechanism is installed on roadway tunneling equipment with the excavation working mechanism, the excavation working mechanism is used for excavating loose rocks or coal mines, and the detection device is a detection drilling machine and used for detecting engineering holes near a drilled roadway. The excavating and detecting arm support mechanism can be widely applied to roadway tunneling equipment with an excavating working mechanism, such as a loader-digger, adrilling and anchoring integrated machine and a drilling and anchoring unit, so that the use of an underground drill rig or an advanced exploring drill rig is canceled, the problem that a drill rod is stuck and a drill is stuck due to deep hole drilling or the problem that the drill cannot be drilled due to hard rock drilling are solved, and tunneling while exploring in the roadway tunneling process is achieved, and the roadway tunneling efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of boom structures, in particular to a digging boom mechanism. Background technique [0002] At present, in the roadway excavation construction of coal mines and non-coal mines, the safety requirements of "every excavation must be explored" must be strictly implemented. Therefore, pre-safety detection and inspection work such as water detection and gas detection must be carried out before roadway excavation. The detection equipment is crawler-type tunnel drilling rig or advanced exploration drilling rig, etc. This type of equipment is specially used for gas or water detection near the roadway, and the detection distance is limited. Once the detection is completed, the equipment should immediately withdraw from the working face, so that roadway excavation equipment such as rock drilling rigs and backhoe loaders can enter the working face; and when the roadway is excavated to the end of the detection distance,...

AI Technical Summary

Problems solved by technology

Once the detection is completed, the equipment should immediately withdraw from the working face, so that roadway excavation equipment such as rock drilling rigs and backhoe loaders can enter the working face; and when the roadway is excavated to the end of the detection distance, the tunnel drilling rig or advanced drilling rig enters the working face again. The detection of the next excavation distance will be carried out on the other side. In such a cycle, there will be a phenomenon that multiple tunnel excavation equipment with different functions need to "wrong vehicle" in the narrow tunnel, which will pose a safety hazard.

[0003] In fact, when the mine is drilling the detection hole, in order to reduce the number of times the equipment enters and exits the working surface, the detection hole should be drilled as deep as possible during operation, so it is easy to appear that the drilling is too deep and the drill cannot be drilled or the drill is stuck. In severe cases, there is a drill rod or a drill bit that cannot be withdrawn, resulting in waste

However, this type of exploration drilling rig is large in size, occupies the space of the roadway, and is inconvenient to enter and exit the working surface, which affects the efficiency of roadway excavation; in addition, due to the single function of this type of equipment, the utilization rate is not high, the idle time is long, and it is easy to rust and damage
