Abstract

The invention provides a conveying device and a conveying method of underwater multi-wheel drilling tools. The conveying device includes a supporting frame, a power head, a guiding column, a power head lifting mechanism, and a conveying mechanism of the wheel drilling tools. The guiding column is fixedly arranged between an upper bottom plate and a lower bottom plate. The power head is located inside the supporting frame and is slidably connected with the guiding column. One end of the power head lifting mechanism is fixedly arranged on the lower bottom plate and the other end of the power head lifting mechanism is fixedly arranged on the power head. The conveying mechanism of the wheel drilling tools is located inside the supporting frame and is fixedly arranged on the periphery of the power head in a surrounding mode. The power head lifting mechanism drives the power head to move up and down along the guiding column. The conveying mechanism of the wheel drilling tools transports thedrilling tools to or gets back the drilling tools from the power head. The drilling tools are conveyed between the wheels. The invention further provides a conveying method of underwater multi-wheel drilling tools. According to the conveying device and the conveying method of underwater multi-wheel drilling tools, the multi-wheel drilling tools are adopted; not only the number is high but also each wheel can independently carry the drilling tools to the power head; and also transferring of the drilling tools to each other can be achieved. In this way, the reliability of drilling down of a drilling machine is greatly improved; the efficiency is high; and the drilling depth is larger.

Description

Technical field [0001] The invention relates to the technical field of heat shrinkable tube packaging equipment, in particular to an underwater multi-wheel drill tool conveying device and method. Background technique [0002] Underwater core sampling drilling rigs are widely used in the exploration of geological archaeology, mineral resources and construction of rivers and lakes. The drilling depth of the underwater core sampling rig depends on the number of drilling tools and the reliability of the docking and loading and unloading of the drilling tools. However, the existing drilling tool conveying device has low working efficiency, poor stability, and shallow drilling depth. [0003] In view of this, the present invention is proposed to solve the shortcomings of the prior art. Summary of the invention [0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide an underwater multi-wheel drill tool conveying device ...
