Description

Technical Field

[0002] An engineering geological survey drill rig is an existing drilling equipment in the prior art that is used to survey the geological conditions of a certain area before carrying out engineering construction in the area. The engineering geological survey drill rig is moved to a designated location in the area, the drilling angle and position of the drill bit and drill rod are adjusted, and then the drill bit and drill rod begin to drill into the formation. As the drill bit and drill rod continue to go deeper, the rock and soil in the borehole and the water added during the drilling process will mix into mud during the rotation of the drill rod. As the drill bit and drill rod rotate downward, the mud in the borehole is gradually discharged through the borehole, forming a mud pool in the drilling area on the surface of the formation. At regular intervals, people will sample and collect the mud discharged from the borehole, and judge the geological conditions deeper in the area by testing the components in the mud samples.

[0003] However, the above-mentioned method for detecting regional geological conditions still has some problems. First, when the drill bit and drill rod drill downward in the borehole, because the drill rod and the inner wall of the borehole are sealed and fitted, if the drill rod encounters smaller objects such as stones during rotation, it is easy for the stones and other objects to be directly bounced up, causing the stones to cause harm to the surrounding operators. In addition, in the prior art, when the engineering geological survey drilling rig drives the drill bit and drill rod to drill downward and the mud flows out through the borehole, it is easy for the subsequent flowing mud to mix with the previous mud before being sampled, thereby affecting the representativeness of the components in the mud for the geological conditions when the subsequent mud is sampled.

When the mud is discharged through the borehole, the bucket-shaped cylinder 7 rises in the conical drilling cylinder 6, leaving a gap between the outer wall of the bucket-shaped cylinder 7 and the inner wall of the conical drilling cylinder 6. At this time, the closed ring plate 31 fits with the inner bottom wall of the bucket-shaped cylinder 7, so that the mud will flow into the space between the outer wall of the bucket-shaped cylinder 7 and the inner wall of the conical drilling cylinder 6, and be collected through the extraction pipe 1 24. When the mud to be sampled and collected flows out of the borehole, the start The first driving motor 21, through the meshing relationship between the meshing gear plate 20 and the meshing gear 19, causes the sliding plate body 18 and the bucket-shaped cylinder 7 to descend in the conical drilling cylinder 6, and the bottom end of the bucket-shaped cylinder 7 fits with the inner bottom wall of the conical drilling cylinder 6, while the closed ring plate 31 does not descend.

The extraction pipe 1 24 and the extraction pipe 25 are both provided with valves. The connecting cylinder 23 is connected to the input end of the slurry delivery pump 22. The connecting conveyor belt 26 is connected to the connecting cylinder 23 and the installation cylinder 5 through a water inlet pipe 27. When it is necessary to extract the mud flowing into the outer wall of the bucket-shaped cylinder 7 and the inner wall of the conical drilling cylinder 6, the valve on the extraction pipe 25 is closed, and the slurry delivery pump 22 is started to allow the mud to enter the slurry delivery pump 22 through the extraction pipe 1 24, the connecting cylinder 23 and the connecting conveyor belt 26. When it is necessary to extract the mud in the bucket-shaped cylinder 7, the valve on the extraction pipe 1 24 is closed to allow the mud to flow into the slurry delivery pump 22. The slurry enters the slurry delivery pump 22 through the extraction pipe 25, the connecting cylinder 23 and the connecting conveyor belt 26. In order to ensure the cleanliness of the connecting cylinder 23, the connecting conveyor belt 26 and the slurry delivery pump 22 and avoid the problem of multiple slurries being mixed together, water can be supplied to the connecting pipeline through the water inlet pipe 27, so that the water passes through the connecting cylinder 23, the connecting conveyor belt 26 and the slurry delivery pump 22 to clean and deliver the connecting cylinder 23, the connecting conveyor belt 26 and the slurry delivery pump 22; The mud discharge assembly includes a discharge cylinder 28, a discharge pipe 29 and a sliding seat 30.

[0022] The working principle of the engineering geological survey drilling rig is as follows: first, the drilling rig body 1 is moved to the designated position, and the position of the movable slide rail 2 and the drill rod driving device 4 is adjusted by the hydraulic moving device 3, so that the drill rod driving device 4 drives the drill bit and the drill rod to pass through the partition cylinder 8, the bucket cylinder 7 and the conical drilling cylinder 6, and the drill rod driving device 4 drives the drill rod and the drill rod to rotate, and drill holes are drilled on the ground, and then the driving electric cylinder 16 is started to drive the fixed plate 17 to descend, so that the installation cylinder 5 and the conical drilling cylinder 6 are descended accordingly, so that The bottom of the conical drilling cylinder 6 is in contact with the ground. During the descent of the conical drilling cylinder 6, the second driving motor 35 is started to drive the conical drilling cylinder 6 to rotate on the outer wall of the mounting cylinder 5 through the meshing relationship between the conical gear ring 33 and the conical gear 34, so that the conical drilling cylinder 6 is in contact with the ground during the rotation process. During the descent of the mounting cylinder 5 and the conical drilling cylinder 6 by driving the electric cylinder 16, the conical drilling cylinder 6 expands the borehole while most of the conical drilling cylinder 6 enters the borehole. During the process of the installation cylinder 5 continuing to descend, the connecting rod 15 gradually tilts between the rotating member 11 and the rotating frame 14 through the two rotating shafts 12, so that the arc-shaped protective plate 9 does not affect the descending operation of the conical drilling cylinder 6. During the rotation of the rotating shaft 12 located in the rotating member 11, the coil spring 13 is gradually tightened. During the process of the installation cylinder 5 ascending, under the torsion of the coil spring 13, the arc-shaped protective plate 9 continues to contact the ground to block stones that may be splashed when the conical drilling cylinder 6 and the drill rod are removed from the borehole. When the mud is discharged through the borehole, the bucket-shaped cylinder 7 rises in the conical drilling cylinder 6, leaving a gap between the outer wall of the bucket-shaped cylinder 7 and the inner wall of the conical drilling cylinder 6, and at this time, the closed ring plate 31 fits with the inner bottom wall of the bucket-shaped cylinder 7, so that the mud will flow into the space between the outer wall of the bucket-shaped cylinder 7 and the inner wall of the conical drilling cylinder 6, and the slurry delivery pump 22 is started, so that the mud enters the slurry delivery pump 22 through the extraction pipe 24, the connecting cylinder 23 and the connecting conveyor belt 26, and then the mud is transported to the discharge cylinder 28, so that the mud is discharged through the corresponding discharge pipe 29. When the mud that needs to be sampled and collected flows out of the borehole, the first drive motor 21 is started, and the meshing gear plate 20 and the meshing gear 19 are engaged. The meshing relationship between them causes the sliding plate body 18 and the bucket-shaped cylinder 7 to descend in the conical drilling cylinder 6, and the bottom end of the bucket-shaped cylinder 7 fits against the inner bottom wall of the conical drilling cylinder 6, while the closed ring plate 31 does not descend. At this time, after the mud is discharged through the borehole, the mud will enter the bucket-shaped cylinder 7 through the gap between the closed ring plate 31 and the inner wall of the bucket-shaped cylinder 7, and the valve on the extraction pipe 1 24 is closed to allow the mud to enter the slurry delivery pump 22 through the extraction pipe 2 25, the connecting cylinder 23 and the connecting conveyor belt 26. After the mud is transported to the discharge cylinder 28, the valve on any discharge pipe 29 is opened to allow the mud to be discharged through the corresponding discharge pipe 29, so that the operator can sample and collect the mud.
