Description

Dig and visit cantilever crane mechanism

Technical Field

The invention relates to the technical field of boom structures, in particular to a digging and exploring boom mechanism.

Background

At present, in the tunneling construction of tunnels of coal mines, non-coal mines and the like, the safety requirement of' tunneling must be strictly executed, so that the early-stage safety detection and inspection work of water detection, gas detection and the like must be carried out before tunneling, most of the detection equipment adopted at present is a crawler-type tunnel drilling machine or an advanced detection drilling machine and the like, the equipment is specially used for detecting gas, water and the like near the tunnels, and the detection distance is limited. Once the detection is finished, the equipment is required to be immediately withdrawn from the working surface, so that the roadway excavation equipment such as the drilling jumbo, the excavating loader and the like can enter the working surface for operation; after the tunnel is tunneled, the tunnel drilling machine or the advanced drilling machine enters the working face again to detect the next tunneling distance, and the process is repeated in such a way, so that the phenomenon that multiple pieces of tunnel tunneling equipment with different functions need to make a vehicle wrong in a narrow tunnel exists, and potential safety hazards exist.

In practice, when drilling and hole measuring are carried out on a mine, in order to reduce the frequency of entering and exiting the working face of equipment, a detection hole is drilled to the depth as far as possible during operation, so that the phenomena of drilling failure or drill clamping due to too deep drilling easily occur, and in severe cases, a drill rod or a drill bit cannot retreat to cause waste. The detection drilling machine has large volume, occupies the space size of the roadway, is inconvenient to enter and exit from the working face, and influences the tunneling efficiency of the roadway; in addition, the equipment has single function, low utilization rate, long idle time and easy corrosion and damage.
