Detailed Description
Referring to FIG. 1, the present invention provides a drilling and sampling apparatus comprising
The support table 1 is provided with a yielding hole for the drilling and production assembly to pass through;
a lifting table 12 disposed above the support table 1; a lifting cylinder 11 for driving the lifting table 12 to lift is also fixedly arranged on the supporting table 1;
preferably, the supporting table 1 is further fixedly provided with a guide rod 17 which is in sliding connection with the lifting table 12; so that the lifting table 12 can stably realize lifting action.
The drilling and production assembly comprises a drilling barrel 2; referring to fig. 2, the drill cylinder 2 has a hollow structure with two through ends, and a plurality of cutting teeth 21 are uniformly arranged on the downward end surface;
the rotating shaft 14 is rotatably arranged on the lifting table 12 in a penetrating way, and one end penetrating out of the lower part of the lifting table 12 is fixedly connected with the rotary table 13 for driving the drilling and production assembly to rotate; the rotating shaft 14 is also in transmission connection with a rotary driving assembly arranged on the lifting table 12; the turntable 13 is detachably connected with the drilling and production assembly;
the support table 1 of the present invention can be mounted on a transfer vehicle or a professional sampling vehicle and transported to a sampling site.
Support feet are arranged below the support table 1, and the support table 1 is fixed on the ground of the sampling area. The lifting cylinder 11 is preferably a hydraulic cylinder, and the lifting table 12 is driven to descend by contraction of the lifting cylinder, and the rotary table 13 abuts against the upper end surface of the drill drum 2 and generates downward pressure on the upper end surface. While pressing down, the rotary driving assembly drives the rotary shaft 14 to rotate, and finally drives the drill drum 2 to rotate.
The cutting teeth 21 of the drill drum 2 are rotated to cut the soil, and gradually drill into the soil layer as the drill drum 2 is pressed down by the force, and the soil sample is integrally pressed into the drill drum 2. Because the soil sample is integrally pressed into the drill cylinder 2, the soil layers are not mixed, and a high-quality sample is provided for subsequent inspection work.
As one embodiment, the rotary driving assembly of the present invention comprises a rotary motor 15 fixed on a lifting table 12, wherein a main shaft of the rotary motor 15 is connected with a driving gear 151; the driving gear 151 is engaged with the driven gear 152 which is sleeved on the rotating shaft 14.
The invention can set the length of the drilling cylinder 2 according to the depth of the sampled soil sample, and simultaneously match the lifting cylinder 11 with proper stroke. As a preferable scheme, the cylinder body of the lifting cylinder 11 can be fixed on the bottom surface of the supporting table 1, and the telescopic rod movably penetrates through the supporting table 1 to be connected with the lifting table 12; the effective sampling length of the drill drum 2 can be increased.
To increase the depth of the borehole sampling, the use of a longer length drill pipe 2 and a lift cylinder 11 matching the long stroke is avoided. As an embodiment, the drilling and production assembly of the invention comprises a drilling barrel 2 and a plurality of connecting barrels 3 which are connected in sequence; wherein the connecting cylinder 3 at the lowest end is connected with the drilling cylinder 2, and the connecting cylinder 3 at the uppermost end is connected with the rotary table 13; the connecting cylinder 3 is a hollow structure with two through ends;
referring to fig. 3 and 7, 4-6 clamping plates 31 are uniformly arranged on the inner wall of the connecting cylinder 3 in a surrounding manner, and the distance between the clamping plates 31 and the upper port of the connecting cylinder 3 is not more than 15cm; a baffle 311 is arranged at one end of the clamping plate 31; the lower port of the connecting cylinder 3 is integrally connected with a plug cylinder 32; the outer diameter of the plug tube 32 is smaller than the inner diameter of the connecting tube 3, and the outer wall of the plug tube 32 is uniformly provided with the same number of clamping blocks 33 as the clamping plates 31 in a surrounding manner; the distance between the clamping block 33 and the lower port of the connecting cylinder 3 is greater than the distance between the clamping plate 31 and the upper port of the connecting cylinder 3;
referring to fig. 4, a plurality of clamping plates 31 are uniformly arranged on the inner wall of the drill cylinder 2 in a surrounding manner; the number of the clamping plates 31 of the drilling cylinder 2 is the same as the number of the clamping plates 31 of the connecting cylinder 3;
the distance between the clamping plate 31 in the drill cylinder 2 and the upper port of the drill cylinder 2 is equal to the distance between the clamping plate 31 in the connecting cylinder 3 and the upper port of the connecting cylinder 3; is convenient to be connected with the connecting cylinder 3.
The assembly and connection mode of the drilling and production assembly comprises the following steps: the operator inserts the plug barrel 32 of the connection barrel 3 into the upper port of the drill barrel 2; the clamping block 33 of the plug-in tube 32 is arranged in advance in a staggered manner with the clamping plate 31 of the drill tube 2. After the plugging tube 32 completely enters the drilling tube 2, the connecting tube 3 is rotated, and the clamping block 33 of the connecting tube enters the lower part of the clamping plate 31 and is abutted with the baffle 311, so that the connecting tube 3 and the drilling tube 2 are connected.
And then the drill cylinder 2 is driven to rotate along with the rotation of the connecting cylinder 3. In the subsequent drilling operation, the connection of the individual connecting cylinders 3 can be completed in sequence in this manner of assembly.
Referring to fig. 5, a cylindrical plug 131 is fixed on the lower end surface of the turntable 13, and the diameter of the plug 131 is the same as the diameter of the plug barrel 32; the outer wall of the plug 131 is uniformly provided with driving blocks 132 with the same number as the clamping plates 31 of the connecting cylinder 3 in a surrounding way;
when the turntable 13 is connected with the connecting cylinder 3, the lifting table 12 slowly descends to enable the turntable 13 to be close to the connecting cylinder 3 until the plug 131 enters the connecting cylinder 3. Slightly rotating the turntable 13 misaligns the drive block 132 with the catch plate 31 of the connecting cylinder 3, after which the lifting table 12 continues to descend until the turntable 13 contacts the upper port of the connecting cylinder 3. After that, the turntable 13 rotates, and the driving block 132 enters below the clamping plate 31 and abuts against the baffle 311, so that the turntable 13 is connected with the connecting cylinder 3.
In the process of docking the turntable 13 with the connection cylinder 3, the phenomenon that the driving block 132 contacts with the top surface of the clamping plate 31 is unavoidable. Because the lifting table 12 drives the turntable 13 to descend, the downward pressure is high, and the generated sliding friction force is high, which may prevent the turntable 13 from rotating and adjusting.
Preferably, the bottom surface of the driving block 132 is embedded with balls 133. When the driving block 132 contacts the top surface of the click plate 31, rolling friction is used instead of sliding friction, and resistance is reduced.
The plug 131 of the rotary table 13 is connected with the connecting cylinder 3 positioned at the uppermost part, and the whole rotation of the drilling and production assembly is driven by the rotation of the rotary table 13.
The rotary table 13 reversely rotates by a slight angle to separate the driving block 132 from the clamping plate 31, and then the lifting table 12 is lifted up, so that the separation of the rotary table 13 from the connecting cylinder 3 can be completed.
The connection or disconnection of the rotary disc 13 to the drill drum 2 can be achieved in the manner described above.
The length of the drill barrel 2 and the connecting barrel 3 of the present invention is the same and may be set to 1 to 1.5 meters. The maximum travel of the lifting cylinder 11 is only required to exceed the length by a certain range, such as 20-50cm. The use of a large stroke lift cylinder 11 is not required.
Drilling and sampling operation:
the turntable 13 is connected with the drill cylinder 2 firstly, and then the lifting table 12 descends to rotationally press the drill cylinder 2 into soil;
afterwards, the rotary table 13 is separated from the drill cylinder 2, the lifting table 12 is lifted, and the first connecting cylinder 3 is connected with the drill cylinder 2; then, the lifting table 12 descends to finish the connection between the turntable 13 and the first connecting cylinder 3;
then, the lifting table 12 is pressed down again to rotationally press the first connecting cylinder 3 into the soil;
then, the turntable 13 is separated from the connecting cylinder 3, the lifting table 12 is lifted, and the second connecting cylinder 3 is connected with the first connecting cylinder 3; then, the lifting table 12 descends to finish the connection between the turntable 13 and the second connecting cylinder 3;
the foregoing actions are then repeated, and the subsequent connecting cylinders 3 are sequentially installed until a predetermined sampling depth is reached.
After the sampling is finished, the drilling and production assembly is lifted up, and one connecting cylinder 3 is detached each time until all the connecting cylinders 3 and the drilling cylinder 2 are recovered. When the connecting tube 3 is recovered and detached, the connecting tube can be marked with a mark so as to facilitate the subsequent analysis and test work.
When lifting, the whole lifting recovery of the drilling and production assembly is realized through the cooperation of the clamping block 33 and the clamping plate 31.
In the recovery, the lifting table 12 is lifted up until the last connecting cylinder 3 is lifted out of the ground.
The rotary motor 15 is then rotated reversely by a certain angle, and the driving block 132 of the turntable 13 is disengaged from the lower side of the clamping plate 31 and abuts against the outer wall of the baffle 311 of the next adjacent clamping plate 31.
Then the rotary motor 15 continues to rotate reversely, so that the clamping block 33 of the connecting cylinder 3 is separated from the clamping plate 31 of the connecting cylinder 3 connected below the rotary motor; the connecting cylinder 3 below is inserted into the soil at this time, and can be kept still under the friction force of the soil and the cylinder wall.
Then, the lifting table 12 is lifted, the rotary table 13 is separated from the last connecting cylinder 3, and then the connecting cylinder 3 is taken down;
after that, the lifting table 12 is lowered, and the turntable 13 is reconnected to the next connecting cylinder 3. After connection, the rotary motor 15 can rotate forward first, so that the connecting cylinder 3 and the connecting cylinder 3 below the rotary motor are prevented from tripping.
Thereafter, the above-described operation is repeated until all the connecting cylinders 3 and the drill cylinders 2 are recovered.
The drilling and sampling assembly realizes large-depth drilling and sampling through the detachable connection of the drilling barrel 2 and the connecting barrel 3. The lifting cylinder 11 with a large stroke is not needed, the whole volume of the equipment is reduced, the equipment is convenient to transport, and the flexibility is high. And meanwhile, the manufacturing cost is greatly reduced.
Referring to fig. 2, as an embodiment, a plurality of auxiliary cutting blades 22 having a certain included angle with the central axis are arranged on the outer walls of the drill cylinder 2 and the connecting cylinder 3; cutting edges 221 are respectively arranged at two ends of the auxiliary cutting blade 22;
the angle between the auxiliary blade 22 and the central axis is preferably 45 deg.. When drilling, the auxiliary cutting blades 22 are respectively inserted into the side walls of the soil layers along with the rotation of the cylinder body, so that the drilling posture of the cylinder body is smoother. Meanwhile, the reaction force generated during drilling is counteracted, and the supporting table 1 does not shake during drilling.
More preferably, referring to fig. 6, a clamping groove 312 is formed at the junction of the clamping plate 31 and the baffle 311;
in the lifting and recovering process, the lifting table 12 is lifted a slight distance, and the respective engaging blocks 33 and the driving blocks 132 are brought into the corresponding engaging grooves 312. Then the rotary motor 15 rotates reversely, and the lifting table 12 ascends to drive each cylinder of the drilling and production assembly to ascend.
When the lifting platform 12 is detached, the lifting platform is firstly lowered for a small distance, so that the clamping block 33 and the driving block 132 are separated from the clamping groove 312; and then repeating the above-mentioned disassembling actions to complete the disassembling and recycling of each connecting cylinder 3.
The drilling barrel 2 and the connecting barrel 3 can be made of stainless steel, and the strength is high. Preferably, the drill cylinder 2 and the connecting cylinder 3 can be made into two semi-cylindrical parts, and then spliced into a complete cylinder. The sample is convenient to open after sampling, and the sample is taken out. The joint surfaces of the two semi-cylindrical parts can be connected in a magnetic attraction mode.
Referring to fig. 8, as an embodiment, a thrust bearing 16 is disposed on each of the top and bottom surfaces of the lifting platform 12 of the present invention; the rotating shaft 14 passes through the centers of the two thrust bearings 16, and two stop rings 141 respectively positioned at two sides of the lifting table 12 are fixedly sleeved on the rotating shaft 14; the two stop rings 141 are respectively in abutting fit with the thrust bearings 16 on the corresponding sides;
during the lowering or raising of the lift table 12, the stopper ring 141 is engaged with the thrust bearing 16 to bear a longitudinal load, thereby improving the load capacity.
In summary, the invention provides a drilling and sampling device, which is characterized in that soil is cut by rotation of cutting teeth of a drill cylinder, meanwhile, the drill cylinder is pressed down by force to gradually drill into a soil layer, and a soil sample is integrally pressed into the drill cylinder. In the sampling process, all layers of soil are not mixed, so that a high-quality sample is provided for subsequent inspection work.
Of course, the present invention is capable of other various embodiments and its several details are capable of modification and variation in light of the present invention, as will be apparent to those skilled in the art, without departing from the spirit and scope of the invention as defined in the appended claims.
