Embodiment 1
[0028] 1. A device for drilling deep holes on the side wall of a pipeline, the purpose of which is to design a drilling tool for the inner wall of a pipeline, including: a structure for realizing the overall axial movement of the drilling device, and a device for realizing the 360-degree circumferential rotational movement of the drilling device The structure realizes the stable tie rod support structure of the front end device of the drilling tool positioned on the inner wall of the pipeline, realizes the front end drill device capable of drilling deep holes and the radial advance and retreat structure, and the synchronous belt pulley and the universal coupling and the bevel gear cooperate. Power transmission system and vision transmission device. The tight cooperation between the above-mentioned parts constitutes a tool for drilling deep holes on the inner wall of the sizing pipeline.
[0029] 2. Since the pipeline is narrow and long, in order to ensure that the drilling too...
Embodiment 2
[0035] The invention relates to a device for drilling deep holes on the side wall of a pipeline, and its purpose is to design a tool capable of drilling deep holes on the inner side wall of a long and narrow pipeline. The pre-experimental devices used in trenchless pipelines, coal and rock exploration, mining and other fields have important scientific significance for promoting the development of rock mechanics, trenchless work inside pipelines, and the construction of experimental platforms for simulating tunnel bolting.
[0036] The purpose of the present invention is achieved like this:
[0037] It includes: a structure to realize the overall axial movement of the drilling device; a structure to realize the 360-degree circumferential rotation of the drilling device; a stable tie rod support structure and a power transmission system to realize the positioning of the front end of the drilling tool on the inner wall of the pipeline; The front-end drill device and power transmi...
