Example Embodiment

[0065] Example 2, as image 3 As shown, the difference from Embodiment 1 is that the base A41 is provided with at least two drilling equipment, and the drill bit 505 of the drilling equipment can advance the drilling in a flush manner to improve the drilling efficiency; the drill bit can also be retracted 505, and let one of the drill bits 505 in the drill hole as a guide for connecting holes.

Example Embodiment

[0066] Example 3, as Figure 4~Figure 12 As shown, the difference from Embodiment 1 is that, preferably, the support frame 3 is a circular frame 31, and the moving mechanism includes a turntable A61 that is connected to the circular frame 31 to move and rotate, and a drive turntable A61 to move and rotate The transfer mechanism A; the drilling equipment is slidably connected to the turntable A61. The turntable A61 is located in the circular frame 31, and the turntable A61 is driven by the transfer mechanism A to move and rotate within the plane defined by the circular frame 31, thereby driving the movement and rotation of the drilling equipment.

[0067] Preferably, as Figure 4~Figure 9 As shown, the transfer mechanism A includes at least two transfer telescopic drive members A305 connected to the circular frame 31, and the working end of the transfer telescopic drive member A305 is provided with a rotatable gear and a drive for the rotation of the drive gear The turntable ...

Example Embodiment

[0078] Example 4, as Figure 13~Figure 15 As shown, the difference from Embodiment 1 is that the supporting frame 3 is connected to the trolley 1 through at least two rocker arms 7; the supporting frame 3 is an arc-shaped frame 33, and the moving mechanism includes an arc-shaped frame 33 The turntable B62 that moves and rotates connected and the transfer mechanism B that drives the turntable B62 to move and rotate; the drilling equipment is slidably connected to the turntable B62; Rotate the telescopic drive member B310, and the working end of the transfer telescopic drive member B310 is provided with a rotatable gear 3101 and a driving member for driving the rotation of the gear 3101; the turntable B62 is provided with a ring gear meshed with the gear 3101; The working end of the telescopic driver B310 is provided with a limit baffle B3102 that limits the position of the turntable B62 to prevent the axial relative displacement of the turntable B62 and the gear 3101; There is...

Abstract

The invention provides a frame type drilling device and a construction method, and the frame type drilling device comprises a supporting frame which is movably and deflectively arranged on a drilling trolley to provide support for drilling equipment; the drilling equipment is movably arranged on the supporting frame, and the drilling equipment can move in all directions in a plane limited by the supporting frame; and the moving mechanism drives the drilling equipment to move on the supporting frame, and continuous hole drilling in the rock mass in any direction is achieved. The device faces an excavation face, multiple arms do not need to be adjusted, and drilling point positions are rapidly positioned; through omni-directional coordinate movement, concentric circle rotation and the like, efficient positioning of drill bits in different forms is achieved, efficiency is improved, and any formed hole contour is drilled; the device works alternately, does not need synchronous work, is simple to operate, and can realize intelligent hole forming to form a required contour.

Description

technical field [0001] The invention relates to the field of continuous hole drilling, in particular to a shelf drilling device and a construction method. Background technique [0002] When tunnels are excavated in the prior art, shock-absorbing holes, slotted holes, positioning holes and other holes need to be arranged on the face of the tunnel. The continuous drilling process is cumbersome, the drilling workload is large, the drilling efficiency is low, and the quality of the hole cannot be guaranteed. If it is not aligned with the direction of the row of holes, it is easy to cause over-excavation or under-excavation, poor alignment of the tunnel contour, and misalignment of blastholes. [0003] The usual method of tunnel excavation is to drill holes in the rock body and fill the holes with explosives to blast the rocks. However, this method will generate large vibration and noise during blasting, which not only has a great impact on the surrounding environment, but also ...
