Embodiment Construction
[0039] The following are specific embodiments of the present invention and combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0040] Please refer to Figure 1-Figure 6 , the invention discloses a reverse arm drilling structure, comprising:
[0041] The support mechanism includes a connecting arm 800, one end of the connecting arm 800 is movably connected to the vehicle body 700, the connecting arm 800 has a first hinge point 810, a second hinge point 820 and a third hinge point 830, the second hinge point 830 The hinge point 820 is located between the first hinge point 810 and the third hinge point 830, and the third hinge point 830 is located at an end away from the vehicle body 700;
[0042] The drilling mechanism is movably connected to the end of the connecting arm 800 away from the vehicle body 700, and the drilling mechanism includes: a drill bit 4...

The invention discloses an inverted arch anti-arm drilling structure, and further discloses an inverted arch anti-arm rock drilling rig, comprising: a support mechanism, which includes a connecting arm, one end of which is movably connected with the vehicle body; the drilling mechanism , is movably connected with the end of the connecting arm away from the vehicle body, the drilling mechanism includes: a drill bit for drilling; a first adjustment assembly, one end of which is movably connected with the connecting arm, and is used to adjust the drilling direction of the drill bit, The turning oil cylinder telescopically drives the first turning block to rotate around the second hinge point. When the turning oil cylinder shrinks until the first hinge point, the second hinge point and the fourth hinge point are on the same straight line, the drill bit The included angle between the axis and the connecting arm is greater than or equal to 20° or less than or equal to 160°. The application realizes that the drilling direction can be adjusted towards the car body and downward, and limits the drilling direction from facing away from the side of the car body. Through the anti-arm drilling structure, the drill bit can be 180° relative to the car body direction of drilling.
Description
technical field [0001] The invention relates to the field of tunnel step method construction drilling devices, in particular to an inverted arch reverse arm drilling structure, in particular to an inverted arch reverse arm drilling structure and an inverted arch reverse arm rock drilling rig. Background technique [0002] The rock drilling rig used in the construction of blasting holes in the inverted arch of the tunnel is relatively complex. The current rock drilling rig can only be drilled facing the drilling surface, and in some special scenarios, there is no operating condition for the car body to be parked facing the drilling surface, and the car body can only be parked on the back of the drilling surface. When it is above the rock and soil, the existing rock drilling rigs cannot drill in the reverse direction during the construction of the inverted arch, and cannot meet the drilling requirements in this use scenario. [0003] The existing Chinese patent publication nu...
