Description

Technical Field

[0001] The invention relates to the technical field of drilling rigs, in particular to a crawler-type multifunctional drilling rig. Background Art

[0002] A drilling rig is a mechanical equipment that drives the drill tool into the ground to obtain physical geological data during the exploration or development of mineral resources (including solid minerals, liquid minerals, gas minerals, etc.).

[0003] For example, the patent with the announcement number CN118855409B discloses a crawler-type multifunctional mechanical core drilling rig, including a crawler chassis, on which a symmetrically arranged mounting frame is fixedly mounted, and a U-shaped plate is rotatably connected to the mounting frame. The invention relates to the field of core drilling technology. The invention adjusts the strength of the striking plate in the striking assembly by adjusting the assembly, so that the vibration force generated by the striking plate hitting the hollow drill just causes the core in the hollow drill to be discharged, effectively avoiding the core being stuck in the hollow drill, and also avoiding the strong striking force, which causes the hollow drill to be damaged. Then, the surface of the hollow drill is cleaned by the cleaning brush in the cleaning assembly to avoid pollutants affecting the rotation of the hollow drill and affecting the removal and quality of the core. At the same time, when the hollow drill is raised, it is convenient to clean the surface soil of the hollow drill to avoid affecting the striking of the striking plate on the hollow drill, effectively improving the working efficiency and reliability of the core drilling rig.

[0019] 3. By setting a cleaning disk, the spring drives the telescopic ring to slide through its own elastic force, and the sliding of the telescopic ring drives the three sets of connecting rods to move synchronously. The movement of the connecting rod drives the linkage slider to slide along the outer wall of the limit strip. The sliding of the linkage slider drives the linkage clamp to fit tightly with the drill rod, so that the rotation of the drill rod drives the linkage frame to rotate synchronously.

The handwheel 802 rotates and drives the rotating guide block 803 to slide through the screw 801. The rotating guide block 803 slides through the rotating guide plate 804 to drive the linkage ring 805 to rotate. The linkage ring 805 rotates and drives the three groups of limiting guide columns 806 to rotate synchronously. The limiting guide columns 806 rotate and drive the limiting clamping rod 807 to swing. The limiting clamping rod 807 swings and drives the guide strip 809 on the outer wall of the limiting roller 808 to fit with the outer wall of the drill rod 601, thereby realizing the limiting operation of the drill rod 601 and avoiding the drill rod 601 from breaking. It should be noted that by setting the spiral guide strip 809, the movement interference of the limiting roller 808 can be avoided when the drill rod 601 is extended or retracted.

[0037] Next, the propeller 503 works to drive the high-speed rotating drill bit 602 to drill the drilling area. At this time, in the linkage frame 11, the spring 1101 drives the telescopic ring 1102 to slide through its own elastic force, and the sliding of the telescopic ring 1102 drives the three groups of connecting rods 1104 to move synchronously. The movement of the connecting rod 1104 drives the linkage slider 1105 to slide along the outer wall of the limit bar 1106. The sliding of the linkage slider 1105 drives the linkage clamping block 1107 to fit tightly with the drill rod 601, so that the rotation of the drill rod 601 drives the linkage frame 11 to rotate synchronously. The rotation of the linkage frame 11 drives the cleaning disk 12 to rotate along the drilling area. The cleaning disk 12 rotates to scrape the dust in the drilling area through the scraping bar 1201. At the same time, the rotation of the cleaning disk 12 drives the sweeping bar 1202 to rotate synchronously, which is convenient for keeping the dust away from the drilling area. It should be noted that the setting of the push block 1103 is conducive to the smooth passage of the drill rod 601 through the linkage frame 11.

[0038] At the same time, when the drill bit 602 drills the drilling area, the drill rod 601 and the drill bit 602 need to be cooled. The cooling water in the water tank 204 is injected into the connecting interface 902 in the connecting pipe 901 through a water pump, and then the cooling water is sprayed out from the nozzle 903 at a high speed to perform water cooling operations on the drill rod 601 and the drill bit 602.

[0039] Finally, after drilling is completed, the drill rod 601 and the drill bit 602 are away from the drilling area. When the drill rod 601 and the drill bit 602 retract, the drill rod 601 and the drill bit 602 contact the cleaning brush 904, thereby cleaning the drill rod 601 and the drill bit 602.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
