Description

Drill boom mechanism, drill explosion assembly and drill explosion trolley Technical Field The invention belongs to the technical field of drilling and blasting, and particularly relates to a drilling and blasting arm mechanism, a drilling and blasting assembly and a drilling and blasting trolley. Background The tunnel drilling and blasting is a common and important excavation method in tunnel and underground engineering construction, and is totally called as a drilling and blasting method, wherein a drilling and blasting trolley (also called as a drilling trolley or a rock drilling trolley) is special equipment for drilling and blasting construction in underground engineering such as tunnels, mines and the like, is mainly used for rock drilling operation, and provides blastholes for subsequent blasting. The core working part of the drilling and blasting trolley is a drilling arm mechanism, the drilling arm mechanism is responsible for drilling positioning, pushing and construction operation, when the existing drilling arm mechanism is used for drilling a rock wall, if the axial pressure born by a main drill rod exceeds the critical buckling load of the main drill rod, bending deformation can occur, but an operator usually cannot find the main drill rod in time, once the main drill rod is bent, the main drill rod can generate larger jumping amount in the radial direction in the drilling process, the hole shape of the drilling is influenced, larger breaking risk exists when the jumping amount of the second main drill rod is too large, once the main drill rod is broken in the drilling, the head end of the main drill rod is difficult to take out of the drilling, and the drilling is scrapped usually. Disclosure of Invention In order to solve the technical problems, one of the purposes of the present invention is to provide a drill arm mechanism which has a simple structure and can monitor the radial runout of a main drill rod in real time so as to avoid the breakage of the main drill rod. In order to achieve the above purpose, the drill arm mechanism comprises a first shell, a first linear driving piece, a first rotary driving piece, a main drill rod and a monitoring piece, wherein the first shell is a strip-shaped shell which is arranged in the front-back direction, a first through hole is formed in the front end of the first shell, a first sliding seat is arranged in the first shell in a sliding mode in the front-back direction, the first rotary driving piece is located in the first shell and is arranged on the first sliding seat, the driving end of the first rotary driving piece faces forward, the first linear driving piece is arranged on the first shell, the driving end of the first linear driving piece is in transmission connection with the first sliding seat, the main drill rod is arranged in the front-back direction, the tail end of the main drill rod extends into the first shell through the first through hole and is connected with the driving end of the first rotary driving piece, the monitoring piece is arranged at the front end of the first shell, the first linear driving piece drives the first sliding seat to drive the first rotary driving piece and the main drill rod to move in the front-back direction, and the main drill rod is used for monitoring whether the main drill rod is in the radial direction to rotate, and the main drill rod is in the front-back driving piece is in the radial direction or not. The technical scheme has the beneficial effects that the main drill rod can move relative to the first shell along the front-back direction under the drive of the first linear driving piece so as to adjust the extending length of the main drill rod on the first shell, the monitoring piece can monitor the radial runout of the main drill rod in real time, when the radial runout of the main drill rod exceeds a certain threshold value, the risk of fracture of the main drill rod can be judged, and at the moment, the main drill rod can be even withdrawn from the drill hole, so that the drill hole is prevented from being scrapped due to fracture of the main drill rod in the drill hole, and the main drill rod can be replaced in time after being withdrawn from the drill hole. In the above technical scheme the monitoring piece includes a mounting section of thick bamboo, a plurality of monitor piece and a plurality of sensing device, the mounting section of thick bamboo is tubular, and its one end inlays and is in first perforation department, the main drilling rod passes the middle part of mounting section of thick bamboo, the monitor piece is the arc, a plurality of monitor pieces are located in the mounting section of thick bamboo, and around the even distribution of main drilling rod circumference interval, every the axial along fore-and-aft direction distribution of monitor piece, just the arc mouth side orientation of monitor piece the main drilling rod, every monitor piece deviates from one side of main
