Description

Technical Field

[0001] This invention relates to the field of geological exploration drilling rig technology, and in particular to a geological exploration drilling rig with a fixed drilling depth for special terrain. Background Technology

[0002] Geological exploration operations are often located in special terrains such as mountains, slopes, gullies, and uneven terrain. Exploration and sampling require strict control of drilling depth to ensure the integrity of soil layer samples and the consistency of depth data. This is a key process in geological exploration, soil and rock testing, and mineral exploration. Existing drilling rigs are mostly fixed single-support structures, which make it difficult to quickly level the entire machine on slopes and uneven ground. Tilting of the drilling frame will cause drill rod deviation, large deviation between the actual drilling depth and the set value, and disordered sample stratification, which directly affects the accuracy of geological testing data. Conventional drilling rigs lack multi-point synchronous leveling mechanisms and rely on adjustment with only a single leg, resulting in low leveling efficiency and poor horizontal accuracy. Therefore, we propose a geological exploration drilling rig with fixed drilling depth for special terrain. Summary of the Invention

A drilling depth adjustment and limiting component 8 is provided on the horizontal drilling frame 7. This embodiment... In the drilling depth adjustment and limiting assembly 8, there are a first motor 9, a lead screw 10, a guide rod 11, a lifting plate 12, a laser rangefinder 29, and a displacement sensor 30.

In this embodiment, a second motor 17 is fixedly installed on the top of the lifting plate 12. An exploration drill rod 18 is fixedly installed at the output end of the second motor 17. Spiral cutting teeth 19 are provided on the outer side of the exploration drill rod 18. An exploration drill bit 20 is fixedly installed at the bottom of the exploration drill rod 18.

[0021] In this embodiment, a base plate 21 is fixedly installed at the bottom of the horizontal drilling frame 7. A guide hole 22 is opened through the top of the base plate 21. A wear-resistant guide ring 23 is fixedly installed inside the guide hole 22. The exploration drill rod 18 is adapted to the wear-resistant guide ring 23. The guide hole 22 and the wear-resistant guide ring 23 can guide and limit the exploration drill rod 18, so that the exploration drill rod 18 can only move in a straight line. In this embodiment, connecting ears 25 are fixedly installed at the top four corners of the mobile frame 1 and the bottom four corners of the horizontal top plate 5. A connecting shaft 26 is rotatably installed inside the connecting ears 25. A connecting block 27 is fixedly installed outside the connecting shaft 26.

Fixing bolts 34 are threaded onto the rotating frames 32, and the fixing bolts 34 abut against the telescopic slide rods 33. The telescopic slide rods 33 can slide inside the rotating frames 32, thereby allowing the rotating abutment plate 35 to abut against the ground. The position of the rotating abutment plate 35 is limited and locked by the limiting ground nails 36, which allows the rotating abutment plate 35, the rotating frames 32, and the telescopic slide rods 33 to provide lateral support for the horizontal top plate 5.

[0024] The specific operation involves the staff pushing the mobile frame 1 and using the multiple rotating wheels 2 mounted on the outside of the mobile frame 1 to transport the entire machine to the exploration point; based on the terrain of the slope and uneven ground at the site, the equipment position is initially aligned and space is reserved for drilling operations. Observe the bubble level 6 fixedly installed on the top of the horizontal top plate 5 to determine the tilt direction of the horizontal top plate 5; synchronously control the extension and retraction of the hydraulic telescopic rod 28 between the connecting lugs 25 installed at the top four corners of the moving frame 1 and the connecting shafts 26 on the inside and the connecting blocks 27 on the outside of the connecting shafts 26 on the outside of the connecting lugs 25 installed at the bottom four corners of the horizontal top plate 5; the hydraulic telescopic rod 28, in conjunction with the telescopic sleeve 3 and the universal joint 4 at the top of the telescopic sleeve 3, adjusts the height of the horizontal top plate 5 synchronously at multiple points until the bubble in the bubble level 6 is centered, thus completing the high-precision level calibration of the whole machine; Rotate the rotating frame 32 inside the mounting slots 31 that are opened through the top left and right sides of the horizontal top plate 5, and rotate the rotating frame 32 downward from the stored state; pull out the telescopic slide rod 33 that is slidably installed inside the rotating frame 32, and adjust the extension length of the telescopic slide rod 33 so that the rotating abutment plate 35 that is rotatably installed on the outside of the telescopic slide rod 33 fits into the ground of the exploration point; tighten the fixing bolts 34 that are threaded on the rotating frame 32 to fix the extension length of the telescopic slide rod 33; insert the limiting ground nail 36 through and slide it into the rotating abutment plate 35 and drive it into the soil layer to complete the limiting and locking of the lateral support structure, form a lateral stable support for the horizontal top plate 5, and prevent lateral slippage during special terrain operations; According to the exploration design requirements, the target drilling depth is determined, and the first motor 9 in the drilling depth adjustment and limiting assembly 8 is started. The first motor 9 drives the screw 10 fixed at the output end to rotate. The screw 10 drives the lifting plate 12 with the outer thread assembly to rise and fall synchronously along the guide rod 11 and the limiting guide groove on the inner side of the horizontal drilling frame 7. The laser rangefinder 29 and displacement sensor 30 fixedly installed on the top of the lifting plate 12 collect the lifting stroke data in real time, and check the depth value with the scale marks 14 on the measuring side plates 13 on the left and right sides of the horizontal drilling frame 7. After adjusting the lifting plate 12 to the position corresponding to the preset depth, the depth locking limiting plug 16 is slid into the limiting slot 15 at the corresponding height of the measuring side plate 13 to form a mechanical rigid limit, locking the maximum downward stroke of the lifting plate 12 and realizing the fixed limit of the drilling depth. Check that the wear-resistant guide ring 23 fixed inside the guide hole 22 at the top of the bottom plate 21 of the horizontal drilling frame 7 is intact and unobstructed; confirm that the exploration drill rod 18 at the output end of the second motor 17 fixed at the top of the lifting plate 12 passes through the wear-resistant guide ring 23, and that the spiral cutting teeth 19 on the outside of the exploration drill rod 18 and the bottom exploration drill bit 20 are undamaged, and that the wear-resistant guide ring 23 constrains the exploration drill rod 18 to move only in a vertical straight line without any left or right deviation or jamming; start the second motor 17, which drives the exploration drill rod 18, spiral cutting teeth 19, and exploration drill bit 20 to rotate synchronously to cut the rock and soil; synchronously control the first motor 9 to slowly lower the lifting plate 12, and the exploration drill rod 18 drills downward at a uniform speed; during the drilling process, the laser rangefinder 29 and displacement sensor 30 continuously monitor the downward depth in real time, and when the lifting plate 12 contacts the depth locking limit rod 16, the mechanical limit stops the lifting plate 12 from continuing to descend, forcibly stopping the drilling, accurately maintaining the preset drilling depth, and obtaining a fixed depth of stratum sample. After single-point exploration and sampling is completed, the first motor 9 is started in reverse, driving the lifting plate 12 and exploration drill rod 18 to rise and reset as a whole; the depth locking limit rod 16 inside the limit slot 15 is pulled out to release the depth limit; the limit nail 36 in the soil layer is pulled out, the fixing bolt 34 is loosened, the telescopic slide rod 33 is retracted into the rotating frame 32, and the rotating frame 32 is rotated upward to be stored in the installation slot 31; the openable maintenance hatch 24, which is rotatably installed on the top of the horizontal drilling frame 7, can be opened to clean the mud and sand inside and inspect the transmission components; after all operations are completed, the hydraulic telescopic rod 28 is controlled to retract and fall back, and the whole machine is transported to the next exploration point by the mobile wheels 2.

[0025] It should be noted that, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
