Description

Technical Field

[0001] This invention relates to the field of continuous hole drilling, and more particularly to a frame-type drilling device. Background Technology

[0002] Under current technology, when excavating tunnels, the working face needs to be equipped with vibration damping holes, slotting holes, positioning holes, etc. The continuous drilling process is cumbersome, the drilling workload is large, the drilling efficiency is low, and it is impossible to guarantee the quality of the holes and the direction of the holes. This can easily lead to over-excavation or under-excavation, poor tunnel outline alignment, misalignment of blast holes, and other problems.

[0003] The conventional method for tunnel excavation involves drilling holes in the rock mass and filling them with explosives for blasting. However, this method generates significant vibration and noise during blasting, which not only has a substantial impact on the surrounding environment but also causes settlement of the surrounding foundations. Furthermore, mechanical excavation often results in cutter head breakage when the rock mass is hard, requiring frequent cutter head replacements and leading to low excavation efficiency. Existing methods for achieving high-efficiency tunnel excavation primarily utilize single or multiple drill rods combined with guiding devices and rock drilling rigs to excavate and break up the rock mass within the tunnel. Guide pipes can be used to create regularly shaped and continuous boreholes for rock breaking.

[0004] However, existing drilling equipment requires the entire machine to be retracted after each drilling operation, reducing equipment flexibility and tunneling efficiency. Furthermore, continuous drilling is a cumbersome process and may result in discontinuous hole arrangement, uneven hole bottoms, and low hole quality. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a frame-type drilling device to solve the problem of cumbersome continuous drilling processes in the prior art.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The support frame 3 is movably and rotatably mounted on a drilling rig 1 to provide support for drilling. Specifically, the support frame 3 is connected to the rig 1 via at least two telescopic main arms 2. These main arms are telescopic drive mechanisms; in this embodiment, the main arms are hydraulic cylinders. The movement of the support frame 3 is achieved through the synchronous extension and retraction of the hydraulic cylinders. The working end of the hydraulic cylinder is connected to the support frame 3 via a hinged seat. By extending some hydraulic cylinders to different degrees and / or shortening others to different degrees, the deflection of the support frame 3 is achieved, thereby driving the drilling equipment to drill in multiple directions. The drilling equipment is movably mounted on the support frame 3 and can move omnidirectionally within the plane defined by the support frame 3. The moving mechanism is mounted on the support frame 3 and connected to the drilling equipment. The moving mechanism drives the drilling equipment to move omnidirectionally within the plane defined by the support frame 3, enabling continuous drilling in any direction on the rock mass.

When the roller is a gear, a corresponding rack is provided on the square frame 32.

[0022] Furthermore, a cross-shaped sliding sleeve is provided on the rear side of the base A41.
