A gap is reserved between the groove plate and the drill boom of the drilling machine, so that electric wires and air circuits on the drill boom of the drilling machine can pass through the gap, and the damage of the fixed groove plate to the circuits and the air circuits on the drill boom of the drilling machine is prevented.
Preferably, the fastener comprises a butterfly bolt and a backing plate, one end of the butterfly bolt penetrates through the groove plate and is in threaded connection with the groove plate, and the backing plate is fixed at the other end of the butterfly bolt.
The backing plate is used for increasing the area of contact of the butterfly bolt and the drill boom of the drilling machine, so that the groove plate is fixed firmly.
Preferably, the angle indicating mechanism comprises an angle scale which is fixedly connected with the groove plate; one end of the pin shaft is fixedly connected with the angle scale; and the pointer is rotationally connected with the pin shaft.
The angle scale can be a sector scale, and scales of the sector scale are symmetrically arranged on two sides of the pointer respectively.
Preferably, the angle dial further comprises a protective edge fixed on the outer edge of the angle dial.
Prevent that the rock that caves up in the drilling process from directly hitting angle indication mechanism.
Preferably, the device further comprises a level fixed on the groove plate.
During installation, the drill boom of the drilling machine is kept vertical, and the level gauge is used for ensuring that the groove plate is horizontally fixed on the drill boom of the drilling machine so as to enable the pointer to indicate the zero position of the angle scale.
The groove plate comprises a bottom plate and side plates fixed on two sides of the bottom plate, and in order to facilitate measurement and installation, angle indicating mechanisms are fixed on the bottom plate and the side plate on one side of the bottom plate, and fasteners are arranged on the bottom plate and the side plates on two sides.
The invention has the beneficial effects that: a gap is reserved between the groove plate and the drill boom of the drilling machine, so that the circuit and the gas circuit on the drill boom of the drilling machine are prevented from being damaged by the fixation of the groove plate; by arranging the base plate, the contact area of the butterfly bolt and the drill boom of the drilling machine is increased, so that the groove plate is firmly fixed; through setting up the protection edge, prevent the direct striking angle indicating mechanism of rock that the drilling process was caved up, the device can be used to instruct the skew degree of rig boom, and the staff of being convenient for in time adjusts to improve construction quality, the device installation is simple, practical, and the material easily acquires with low costs, easily operation.
