Abstract

The invention discloses an adjustable drill bit device for a drilling machine, which specifically relates to the technical field of drilling machines, and comprises a mobile body, which moves upwards through a first connecting column, a mounting plate and a top frame. At this time, the top frame moving upwards will push the mounting seat, and then the moving mounting seat will drive the second connecting column to move, and then drive a micro spring telescopic displacement sensor to move at the same time. At this time, the eccentric distance generated by the low-speed rotating extension rod will be fed back to the control system of the mobile body through the micro spring telescopic displacement sensor. The control system of the mobile body uses multiple electric motors to drive multiple screws to rotate, and then drives multiple second adjustment push heads to move under the threaded transmission action of multiple threaded sleeves and multiple screws, and pushes multiple extension rods to adjust the deflection, thereby achieving the effect of preventing multiple forming hole drills from being affected by the deflection problem when in use.

Description

Technical Field

[0001] The present invention relates to the technical field of drilling machines, and in particular to an adjustable drill bit device for a drilling machine. Background Art

[0002] A drilling rig is a mechanical device used to drive the drill tool to drill underground to obtain physical geological data. Its main function is to drive the drill tool to break the rock at the bottom of the hole, and to lower or extract the drill tool in the hole. It is often used to drill rock cores, ore cores, rock cuttings, gas samples, liquid samples, etc., to explore underground geology and mineral resources. Drilling rigs can be classified according to their use and structure. According to the use, drilling rigs include mining drills, construction drills, water conservancy drills and geological exploration drills. Mining drills are mainly used for mining prospecting, rock blasting and drilling holes in mine working faces; construction drills are used for drilling holes in deep foundation pits, pile foundations and tunnels in construction; water conservancy drills are used for drilling holes in water conservancy projects such as hydropower stations and embankments; geological exploration drills are mainly used for geological exploration and stratum sampling. According to the structure, drilling rigs include manual drilling rigs, electric drilling rigs and hydraulic drilling rigs.

[0003] In the prior art, ground drilling operations often require the use of various drilling rigs. In deep drilling operations, the drilling rig generally needs to add an extension rod before drilling. However, the extension rod usually has a center deviation with the drilling rig axis during installation, and the general drilling rig cannot measure and adjust the eccentricity of the added extension rod. After the drill bit is installed, its eccentricity will be magnified due to its position at the bottom of the extension rod, which will cause the drill bit to swing during use, thereby affecting its drilling effect. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an adjustable drill bit device for a drilling machine to solve the problems raised in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

Fixing effect, after the above steps are completed, the staff uses multiple electric motors through the control system of the mobile body, and then the driving shafts of the multiple electric motors will drive the multiple screws to rotate, and then under the threaded transmission action of the multiple threaded sleeves and the multiple screws, the multiple connecting plates will drive the multiple second adjustment push heads to move, and push the multiple extension rods fixed by the auxiliary clamping assembly to adjust the deflection. When the deflection of a single position of the extension rod is pushed by the second adjustment push head, the control system of the mobile body will restart the pneumatic chuck to clamp and fix the extension rod, and at the same time the auxiliary clamping assembly will release the clamping of the extension rod, and the drilling rig body will drive the extension rod to rotate to replace the position to be adjusted. The above steps can be repeated to calibrate the coaxiality of the multiple extension rods, thereby achieving the effect of preventing the use of multiple forming hole drills from being affected by the deflection problem during use.

At this time, the third connecting column will push the first mounting rod to rotate, and then the multiple clamping plates inside the multiple connecting shells will clamp the extension rods, and then when the extension rods are adjusted, since the clamping plates and the ball head connecting rods can be rotated, the clamping position of the threaded adjustment column can be adjusted, thereby achieving auxiliary clamping of the extension rods and facilitating the change of position when multiple extension rods are adjusted.

At this time, the inclined second electric hydraulic rod and the inclined installation frame will drive the angles of multiple drilling rig bodies to change, thereby achieving the effect of facilitating the inclined drilling of multiple drilling rig bodies.

[0021] Preferably, two guide rods are fixedly installed inside the first mounting seat, and the guide rods are slidably connected to the connecting plate.

[0031] In summary, the present invention mainly has the following beneficial effects:

[0032] The first connecting column, the mounting plate and the top frame move upward, and the top frame moving upward will push the mounting seat, and then the moving mounting seat will drive the second connecting column to move, and then drive the micro spring telescopic displacement sensor to move at the same time.

[0050] Working principle: Please refer to Figure 1-Figure 11As shown, when in use, the staff connects the external air pump to the multiple pipe joints 33 through a hose, and then the staff installs the extension rod 30 with the rotating shafts of the multiple pneumatic chucks 29, and then the staff starts the drilling rig body 3 and makes it rotate at a low speed, and then the staff uses the external air pump, and then the external air pump will deliver gas to the inside of the pushing assembly, and then the mounting seat 39 will be pushed and moved, and then the moving mounting seat 39 will drive the second connecting column 43 to move, and make it squeeze the first spring 44, and then the moving mounting seat 39 will drive the micro spring telescopic displacement sensor 40 inside it to move at the same time, at this time, the ball head part of the telescopic detection rod of the micro spring telescopic displacement sensor 40 will contact the outer wall surface of the extension rod 30, and then the eccentric distance generated by the low-speed rotating extension rod 30 will be fed back to the control system of the mobile body 1 through the micro spring telescopic displacement sensor 40, and then the control system of the mobile body 1 will start the auxiliary clamping assembly to clamp the multiple extension rods 30, and at the same time the control system of the mobile body 1 will stop drilling. The driving shaft of the machine body 3 rotates, and the multiple pneumatic chucks 29 release the fixing effect of the multiple extension rods 30. After the above steps are completed, the staff uses the multiple electric motors 15 through the control system of the mobile car body 1, and then the driving shafts of the multiple electric motors 15 will drive the multiple screws 67 to rotate, and then under the threaded transmission action of the multiple threaded sleeves 65 and the multiple screws 67, the multiple connecting plates 68 will drive the multiple second adjustment push heads 69 to move, and push the multiple extension rods 30 fixed by the auxiliary clamping assembly to adjust the swing. When the swing of a single position of the extension rod 30 is pushed by the second adjustment push head 69, the control system of the mobile car body 1 will restart the pneumatic chuck 29 to clamp and fix the extension rod 30, and the auxiliary clamping assembly will release the clamping of the extension rod 30, and the drilling rig body 3 will drive the extension rod 30 to rotate to replace the position to be adjusted. By repeating the above steps, the coaxiality of the multiple extension rods 30 can be calibrated, thereby achieving the effect of preventing the use of multiple forming hole drills 31 from being affected by the swing problem during use.
