Description

Technical Field

[0001] The utility model relates to the technical field of rope coring, in particular to a rope coring and hole-reaming drill tool. Background Art

[0002] Rope coring is an advanced drilling technology that is of great significance in fields such as geological exploration. During the rope coring process, cores are taken through a special drilling tool system. A special rope channel is provided in the drill pipe. When the drill bit reaches a certain depth at the bottom of the well, the inner tube containing the core can be quickly extracted from the drill pipe to the ground using a rope without lifting the entire drill pipe. This technical advantage is significant. It greatly reduces the time for drilling and drilling, and improves drilling efficiency. At the same time, it can effectively avoid the disturbance of the hole wall caused by frequent lifting of the drill pipe, reduce the incidence of accidents in the hole, and ensure the continuity and stability of the drilling work. Rope coring technology is also crucial for obtaining high-quality core samples. It can provide more accurate and complete geological information for geological research, mineral exploration, etc., help scientists and engineers to have a deeper understanding of underground geological structure and mineral distribution, and provide strong technical support for resource development and geological science research.

[0003] For example, the utility model with announcement number CN206144501U discloses a rope coring system, which includes a drill pipe and a core barrel, a rope retracting mechanism, a hoisting rope, and a coring mechanism. The coring mechanism includes a suction mechanism, a mounting frame, a friction reduction mechanism, a line position adjustment mechanism, and two clamping arms. The line position adjustment mechanism is fixedly mounted on the top of the mounting frame, the friction reduction mechanism is fixedly mounted on the outer edge of the mounting frame, and the two clamping arms are mounted on the mounting frame. The bottoms of the two clamping arms are provided with claws for hooking the spearhead, and the suction mechanism is fixedly mounted on the mounting frame. This rope coring system uses the suction mechanism to tighten the two clamping arms, thereby clamping the core barrel. This ensures that even when the friction between the drill pipe and the core barrel increases, the core barrel will not separate from between the two clamping arms.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] There is greater friction when the core is taken out. Utility Model Content

[0006] The utility model discloses a rope coring and reaming drill tool, which aims to solve the technical problem of relatively large friction when taking out the rock core.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A rope coring and reaming drilling tool comprises an outer shell, an outer side surface of the outer shell is provided with a hole, the upper surface of the outer shell is fixedly connected to a support rod, the top end of the support rod is fixedly connected to a connecting frame, the inner cavity of the connecting frame is fixedly connected to a motor, the output end of the motor is installed with a rotating rod through a coupling, the bottom end of the outer shell is provided with a drilling mechanism, the drilling mechanism comprises a limiting ring, the limiting ring is fixedly connected to the bottom end of the outer shell, the outer surface of the limiting ring is rotatably connected to the rotating ring, the lower surface of the rotating ring is fixedly connected to a rotating tube, and the bottom end of the rotating tube is fixedly connected to a drill disc; the outer side surface of the outer shell is penetrated by a stabilizing mechanism.

[0009] By setting up a motor, after connecting to the power supply and turning on the switch, the rotating rod can be rotated, thereby causing the drilling mechanism to rotate. By setting up the drilling mechanism, the rock core can be drilled when the rotating rod rotates. By setting up a limit ring, the rotating ring can be limited so that the rotating ring can rotate on the outer surface of the limit ring, thereby causing the rotating tube to rotate. By setting up a drill disc, the extension can be drilled when the rotating tube rotates. By setting up a stabilizing mechanism, the rock core can be limited when it is taken out, so that the rock core can be moved up stably.

[0010] In a preferred embodiment, the drilling mechanism also includes a rotating disk, which is fixedly connected to the end of the rotating rod away from the motor, the lower surface of the rotating disk is fixedly connected to a connecting plate, the bottom end of the connecting plate is fixedly connected to the inner ring of the rotating circle, the inner cavity of the rotating tube is slidably connected to a sliding tube, the upper surface of the sliding tube is fixedly connected to a connecting rod, the end of the connecting rod is fixedly connected to a spear head, the inner wall of the sliding tube is fixedly connected to a washer, and the bottom of the inner wall of the sliding tube is fixedly connected to an anti-slip ring.

[0011] By arranging a rotating disk and a connecting plate, the rotating disk and the connecting plate can be rotated when the rotating rod rotates, thereby causing the rotating circle to rotate. By arranging a sliding tube, it can slide in the inner cavity of the rotating tube. By arranging a spear head, it can be connected to a rope, thereby allowing the sliding tube to be pulled. By arranging a washer and an anti-slip ring, the friction between the sliding tube and the rock core can be increased.

[0012] In a preferred solution, the stabilizing mechanism includes a fixed frame, the fixed frame passes through the outer surface of the outer shell, a track groove is provided on the outer side of the fixed frame, a sliding sleeve is slidably connected to the track groove provided on the outer surface of the fixed frame, a spring is fixedly connected to the outer side of the sliding sleeve, the end of the spring is fixedly connected to a fixed block, the fixed block is fixedly connected to the outer side of the fixed frame, a rotating block is rotatably connected to the inner cavity of the sliding sleeve, and a roller is fixedly connected to the side of the rotating block away from the sliding sleeve.

[0013] By providing a fixed frame and opening a track groove on the outer side of the fixed frame, the sliding sleeve can slide stably on the outer side of the fixed frame. By providing a spring, the sliding sleeve can be squeezed, so that the sliding sleeve is always subjected to an extrusion force toward the outer shell. By providing a rotating block and a roller, rotation can be generated in the inner cavity of the sliding sleeve, and the roller can be rotated when the core moves.

[0014] As can be seen from the above, a rope coring and reaming drill has the following improvements and advantages compared with the prior art:

[0015] First: by setting up a motor, after connecting to the power supply and turning on the switch, the rotating rod can be rotated, thereby causing the drilling mechanism to rotate. By setting up the drilling mechanism, the core can be drilled when the rotating rod rotates. By setting up a limit ring, the rotating ring can be limited so that the rotating ring can rotate on the outer surface of the limit ring, thereby causing the rotating tube to rotate. By setting up a drill disc, the extension can be drilled when the rotating tube rotates.

[0016] Secondly, by setting a stabilizing mechanism, the rock core can be limited when it is taken out, so that the rock core can be moved up stably. BRIEF DESCRIPTION OF THE DRAWINGS
