Description

Technical Field

[0001] The invention relates to the technical field of core drilling, in particular to an anti-drift energy-saving core drilling device and a method. Background Art

[0002] Core drilling technology is often used in geological surveys to obtain underground core samples, and the underground geological structure is evaluated based on the core samples. Single-tube core drilling is a commonly used drilling sampling method. Its main principle is that the drill bit and the core tube are installed together, the drill bit drills into the ground and breaks the rock, the broken core enters the core tube, and then the core sample is obtained by taking out the core tube;

[0003] Core types can generally be divided into shale that is easily broken, mudstone that needs to be stored in a moisturizing manner, and granite that is not easy to break. At present, when taking out the core inside the core tube, it is usually done manually by using tools to knock on the core tube while dumping the core. This method can easily cause the fragile core to scatter, and can also easily cause the core that needs to be moisturized to dehydrate and crack in the air, affecting the accuracy of the subsequent core sample inspection results. In addition, the lifting mechanism used to suspend the core tube on most core drilling equipment has a single function, which is not easy to assist the core to be separated from the core tube, nor is it easy to assist the core tube to move down for drilling, which leads to poor effect of the lifting mechanism in energy-saving optimization of the power system. Summary of the invention

[0004] The object of the present invention is to provide an anti-drift energy-saving core drilling device and method to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] A base plate, a top surface of which is fixed with a plurality of guide posts;

[0008] A drilling mechanism is slidably connected to a plurality of guide columns, the drilling mechanism comprises a carrier plate, the bottom of the carrier plate is rotatably connected to a transmission shaft, the bottom of the transmission shaft is transmission-connected to a plurality of core tubes, both ends of the core tubes are fixed with connectors, and a hinge assembly is provided between two adjacent connectors;

[0009] A lifting mechanism is arranged on the top of the carrier plate, the lifting mechanism comprises a bracket, and an electric hoist capable of pulling the carrier plate to move is installed on the top of the bracket;

[0010] Two horizontal sampling pieces are respectively installed at two ends of the base plate, and the horizontal sampling pieces include a supporting plate and a sleeve;

[0011] Two vertical sampling parts are respectively installed on both sides of the substrate. The vertical sampling parts include U-shaped plates, and a plurality of sleeves are arranged inside the U-shaped plates, and a plurality of second inserting rods are arranged on the tops of the U-shaped plates.

[0012] Furthermore, the drilling mechanism further includes:

[0013] A gasoline engine is fixedly connected to the carrier plate, and the gasoline engine can drive the transmission shaft to drive a plurality of core barrels to rotate;

[0014] A drill bit is fixedly installed with the connector at the corresponding position.

[0015] Furthermore, the vertical sampling part further includes:

[0016] A clamping plate is fixedly installed on the top of the U-shaped plate through bolts, and the clamping plate and the U-shaped plate can cooperate to clamp and fix the core barrel;

[0017] A connecting block is fixedly connected to a plurality of second inserting rods. Connecting plates are fixed at both ends of the carrier plate, and the connecting block is movably inserted into the connecting plate.

[0018] Furthermore, the hinge assembly includes two first movable seats, the first movable seats are slidably clamped with the connectors at the corresponding positions, and a second movable seat is rotatably connected between the two first movable seats.

[0019] Furthermore, the hinge assembly further includes two pin shafts, and the pin shafts are detachably and rotatably inserted between the first movable seat and the second movable seat.

[0020] Furthermore, a U-shaped frame sleeved with the hook of the electric hoist is fixed on the top of the carrier plate, and a plurality of limiting grooves are opened on the outer sides of both ends of the bracket.

[0021] Furthermore, traction ropes that are movably clamped with the limiting grooves at the corresponding positions are arranged at both ends of the bracket. One end of the traction rope is detachably fixed to the carrier plate, and a sleeve ring is fixed to the other end of the traction rope.

[0022] Furthermore, the horizontal sampling part further includes two shaft rods, the support plate and the sleeve are respectively fixedly connected to the shaft rods at the corresponding positions, a plastic bag is sleeved at the open end of the sleeve, and a first inserting rod is movably inserted into the open end of the sleeve.

[0023] Furthermore, an anti-deviation assembly is arranged in the middle of the substrate. The anti-deviation assembly includes a ring fixedly connected to the substrate, two L-shaped shafts are movably inserted into the top of the ring, and an arc-shaped plate is fixed to the top of the L-shaped shafts.

[0024] The present invention also provides a usage method of an anti-deviation energy-saving core drilling equipment, and the method specifically includes the following steps:

[0025] Step 1: Set up and install the drilling equipment. Connect the hook of the electric hoist to the U-shaped frame, and the electric hoist lifts the carrier plate to the top position of the support.

[0026] Step 2: Take out three core tubes connected end to end. Fix the connection head of the uppermost core tube to the transmission shaft, and fix the connection head of the lowermost core tube to the drill bit.

[0027] Step 3: The gasoline engine drives the transmission shaft 220 to rotate. The transmission shaft drives multiple core tubes to rotate. The electric hoist lowers the hook to move the entire drilling mechanism downward, and the core tubes drill into the ground.

[0028] Step 4: After the carrier plate drops to near the ground, disassemble and separate the transmission shaft from the core tubes. The electric hoist lifts the carrier plate and the transmission shaft and moves them to the top of the support.

[0029] Step 5: Install an appropriate number of core tubes between the transmission shaft and the core tubes that have already been drilled into the ground. The drilling mechanism moves downward again for drilling, so that the core tubes can move to a deeper position underground. The deeper the drilling depth, the more core tubes are installed.

[0030] Step 6: The electric hoist lifts the carrier plate to move the drilling mechanism upward, and multiple core tubes are pulled out of the ground.

[0031] Step 7: Use a vertical sampling piece to assist in taking out the non-fragile core inside the core tube, and use a horizontal sampling piece to assist in taking out the fragile core inside the core tube.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. By fixing connection heads at both ends of the core tube and arranging a hinge assembly between adjacent connection heads, the hinge assembly can enable adjacent core tubes to rotate. When the core sampled inside the core tube is a fragile core sample, the core tube pulled out of the ground can be rotated 90 degrees by using the hinge assembly, so that the core tube is horizontally arranged on the pallet (refer to Figure 9 ), pre-sleeve a plastic bag on the open end of the sleeve, and then gradually insert a first inserting rod into the core tube, so that the fragile core sample inside the core tube is pushed into the sleeve together with the plastic bag from the open end of the sleeve, realizing the transfer of the fragile core into the plastic bag. Subsequently, take out the plastic bag from the open end of the sleeve, realizing the convenient extraction of the fragile core sample contained in the plastic bag, and eliminating the fragmentation and scattering of the fragile core when it lands due to manual direct pouring of the core tube.

[0034] During the sampling process of the core sample, it can be stored in a plastic bag with the help of a horizontal sampling piece. If the core is a core sample that needs to be stored moisturized, the bag mouth of the plastic bag can be sealed, thereby effectively preventing the core from dehydrating and cracking in the air, achieving the effect of storing the core in a sealed manner.

[0035] 2. When the core sampled inside the core barrel is a non-fragile core sample, referring to Figure 7 and Figure 8 , multiple removed core barrels can be rotated and abutted against each other end to end. Then, the multiple juxtaposed core barrels are clamped and installed between the C-shaped plate and the clamping plate. The connecting block with multiple second inserting rods is installed on the connecting plate of the carrier plate. During the drilling process when the lifting mechanism releases the carrier plate and makes it move downward, the carrier plate can drive the connecting block to move downward, causing the multiple second inserting rods to move downward. The second inserting rods move downward and are inserted into the vertically juxtaposed core barrels, which helps to push out the non-fragile core sample that is difficult to fall inside the core barrel from the core barrel. Similarly, plastic bags can be pre-sleeved on the openings of multiple casing pipes, so that the vertically falling core can fall into the plastic bags through the casing pipes, realizing the sealed storage of non-fragile core samples that need to be stored with moisture. This saves the labor of knocking on the core barrel while pouring out the core that is difficult to fall, which is beneficial to improving the efficiency of core sampling.

[0036] 3. By passing and clamping traction ropes through both ends of the bracket, one end of the traction rope is fixedly installed with the carrier plate, and the other end of the traction rope is fixedly installed with the hook of the electric hoist. When encountering a rock formation that is difficult to drill underground, when the electric hoist winds up the rope, the hook moves upward. The hook upwardly pulls the traction rope, and the traction rope downwardly drags the carrier plate, so that the entire drilling mechanism is subjected to a downward pressure. Combining with the gravity of the drilling mechanism itself, it helps the drilling mechanism to drill a special rock formation with a harder texture with a greater downward pressure;

[0037] The electric hoist lifts the hook to make the traction rope drag the carrier plate, which is convenient for assisting the drilling mechanism to move downward to drill a special rock formation. The electric hoist lifts the hook to make the C-shaped frame drive the entire drilling mechanism to move upward, which is convenient for pulling out multiple core barrels for auxiliary sampling. The electric hoist lowers the hook to make the carrier plate move downward under the action of the gravity of the drilling mechanism itself, which is convenient for the carrier plate to drive the vertical sampling piece to automatically take out the core sample that is difficult to fall. Thus, the diversity of the functions of the lifting mechanism is enriched, which helps to improve the effect of the lifting mechanism in terms of energy-saving optimization of the power system.

Specific embodiments

[0048] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] Embodiment 1, please refer to Figure 1 - Figure 9, in the embodiments of the present invention, an anti-offset energy-saving core drilling device and method include a base plate 100. Guide columns 110 are fixed at the four corners of the top surface of the base plate 100. A drilling mechanism 200 is arranged between the multiple guide columns 110. The drilling mechanism 200 includes a carrier plate 210 slidably connected to the multiple guide columns 110. A transmission shaft 220 is rotatably connected to the bottom of the carrier plate 210. Multiple core tubes 240 are drivingly installed at the bottom of the transmission shaft 220. Connection heads 250 are fixed at both ends of the core tubes 240. An articulated assembly 300 is arranged between two adjacent connection heads 250. The articulated assembly 300 can enable two adjacent core tubes 240 to rotate. A lifting mechanism 400 is arranged at the top of the carrier plate 210. The lifting mechanism 400 includes a bracket 410 fixedly connected to the base plate 100. An electric hoist 420 is detachably installed and fixed at the top of the bracket 410. The electric hoist 420 is used to traction the carrier plate 210 to move up and down. Horizontal sampling members 500 are arranged at both ends of the top surface of the base plate 100. The horizontal sampling members 500 include a support plate 510 and a sleeve 520 arranged horizontally. The support plate 510 is used to support the core tube 240 containing the core. The sleeve 520 is used to hold the fragile core pushed out from the core tube 240. Vertical sampling members 600 are installed on both sides of the top surface of the base plate 100. The vertical sampling members 600 include a U-shaped plate 610 fixedly connected to the base plate 100. A plurality of sleeves 620 fixedly connected to the base plate 100 are arranged inside the U-shaped plate 610. A plurality of second inserting rods 630 are arranged at the top of the U-shaped plate 610. The second inserting rods 630 are drivingly connected to the carrier plate 210. The second inserting rods 630 are used to push out the core inside the vertically arranged core tube 240.

[0050] Specifically, by designing multiple core tubes 240 with traditional end-to-end screwing and fixing into a form where the adjacent core tubes 240 can rotate and adjust their positions at the ends, it helps to place a single core tube 240 horizontally or multiple core tubes 240 vertically. By arranging a sleeve 520 at the end of the horizontally placed core tube 240, a plastic bag 521 is sleeved at the open end of the sleeve 520. By inserting a first inserting rod 522 into the core tube 240, the fragile core can be slowly pushed into the plastic bag 521 inside the sleeve 520, effectively preventing the fragile core from spilling during sampling. By placing a sleeve 620 at the bottom of the vertically placed core tube 240, a plastic bag 521 is sleeved at the open end of the sleeve 620, and a plurality of second inserting rods 630 are placed at the top of the vertically placed core tube 240. By inserting the second inserting rods 630 into the core tube 240, the non-fragile core that is difficult to fall can be slowly pushed into the plastic bag 521 inside the sleeve 620, and the bag mouth of the plastic bag 521 containing the core can be sealed, effectively preventing the core that needs to be moisturized from dehydrating and cracking in the air. Thus, reasonable sampling and storage can be realized according to the types of cores in different drilling areas, which is beneficial to ensuring the integrity of the core samples.

[0051] Such asFigure 5 As shown, in this embodiment, the drilling mechanism 200 further includes a gasoline engine 230 fixed to the top surface of the carrier plate 210. On one side of the gasoline engine 230, a speed reducer 231 fixedly connected to the carrier plate 210 is arranged. The output end of the gasoline engine 230 is fixedly installed with the input end of the speed reducer 231, and the output end of the speed reducer 231 is drivingly connected to the transmission shaft 220.

[0052] In this embodiment, the output end of the gasoline engine 230 drives the transmission shaft 220 to rotate through the speed reducer 231, and the transmission shaft 220 drives the core barrel 240 fixedly installed at its bottom to rotate, so as to enable the plurality of core barrels 240 connected end to end to perform rotary drilling work. Among them, the gasoline engine 230 and the speed reducer 231 are both well-known mechanical equipment in the prior art, and the specific working principle will not be elaborated.

[0053] In this embodiment, a threaded groove can be opened inside the connector 250, and a threaded post can be fixed at the bottom of the transmission shaft 220 to realize screwing and fixing the core barrel 240 to the bottom of the transmission shaft 220 through the connector 250, which is convenient for the transmission shaft 220 to drive the core barrel 240 connected thereto to perform rotary drilling later. Combined Figure 6 , a connector 250 can also be fixed at the bottom of the transmission shaft 220, and then the two connectors 250 are installed together through the hinge assembly 300, so that the transmission shaft 220 and the core barrel 240 at its bottom are detachably installed together. The connection and fixing method of the transmission shaft 220 and the core barrel 240 can be flexibly selected according to needs.

[0054] As Figure 2 and Figure 5 shown, in this embodiment, a drill bit 260 is detachably screwed and fixed below the connector 250 of the core barrel 240 at the bottom of the drilling mechanism 200. During the drilling process, the drill bit 260 can break the rock formation along a circular trajectory, so that the core sample moves down with the core barrel 240 and enters the inside of the core barrel 240.

[0055] As Figure 7 and Figure 8 shown, in this embodiment, the vertical sampling member 600 further includes a clamping plate 611 bolted and fixed to the top of the C-shaped plate 610. The clamping plate 611 and the C-shaped plate 610 cooperate to clamp and fix the core barrel 240.

[0056] In this embodiment, when it is necessary to take out the core samples that are not easy to fall from the inside of multiple core tubes 240, multiple side-by-side core tubes 240 are clamped to the top of the 匚-shaped plate 610, and then the arc-shaped notch of the clamping plate 611 is clamped to the outside of the core tube 240, and then the clamping plate 611 is fixed to the outside of the multiple core tubes 240 with bolts, so that the multiple core tubes 240 are fixed to the top of the 匚-shaped plate 610. As the carrier plate 210 moves downward, the multiple insertion rods 630 can be respectively inserted into the inside of the core tubes 240 at different positions, which facilitates the pushing down of the core samples inside the core tubes 240. In addition, the core tubes 240 are placed vertically, which also helps the core samples to fall quickly.

[0057] In this embodiment, combined with Figure 2 A plurality of sleeves 620 are arranged below the plurality of clamped core tubes 240. The sleeves 620 are detachably fixed on the top of the substrate 100 and correspond to the bottom opening of the core tube 240 at the corresponding position. The plastic bag 521 can be sleeved on the pipe mouth of the sleeve 620. As the core sample falls, the core sample that falls on the plastic bag 521 moves into the sleeve 620, and finally the core sample is contained in the plastic bag 521. The plastic bag 521 is arranged inside the sleeve 620. At this time, the sleeve 620 can be removed, and the plastic bag 521 can be drawn out from the sleeve 620 to transfer the core sample to the plastic bag 521. The plastic bag 521 can not only seal and protect the core sample, but also prevent the broken core from falling to the ground.

[0058] like Figure 1 , Figure 5 and Figure 8 As shown, in this embodiment, a plurality of second plug rods 630 are fixedly connected to the top with a connecting block 640, and both ends of the carrier 210 are fixed with connecting plates 270. The connecting block 640 is movably connected with the connecting plate 270. When the carrier 210 needs to move down with the plurality of second plug rods 630, the connecting block 640 is pre-installed on the connecting plate 270. Figure 4 The protrusion on the top surface of the connecting plate 270 can limit the position of the connecting block 640. After the connecting block 640 is installed, the multiple insertion rods 630 at the bottom thereof can be arranged at the corresponding position above the opening of the core tube 240.

[0059] like Figure 6 As shown, in this embodiment, the hinge assembly 300 includes two movable seats 1 310, a slot 253 is provided inside the connecting head 250, the movable seat 1 310 is slidably engaged with the slot 253 at the corresponding position, and a movable seat 2 320 is detachably and rotatably connected between the two movable seats 1 310. A slot 251 is also provided inside the connecting head 250, and an insert block 252 is fixed inside the slot 251. The width of the slot 251 is twice the width of the insert block 252, so that the insert block 252 can be adapted to be inserted into the corresponding slot 251.

[0060] In this embodiment, during the downward drilling process of multiple core barrels 240, the entire hinge assembly 300 can be received between two adjacent card slots 253, and the insertion block 252 can be inserted into the corresponding insertion slot 251. Combining Figure 1 , at this time, the end faces of two adjacent connectors 250 are in contact. Under the connection action of the hinge assembly 300 and the insertion block 252, multiple core barrels 240 can rotate and drill simultaneously. During the process of pulling out the core barrel 240, the hinge assembly 300 is removed from the inside of the card slot 253, and the insertion block 252 is removed from the inside of the insertion slot 251. Combining Figure 3 , the two adjacent connectors 250 are separated. At this time, the user can use an external cutting tool to cut the core along the gap between the two connectors 250, and then multiple core barrels 240 can be disassembled as needed and placed on the vertical sampling piece 600 to assist in sampling. Combining Figure 9 Alternatively, a single core barrel 240 can be rotated 90 degrees and arranged on the horizontal sampling piece 500 to assist in sampling.

[0061] As Figure 8 shown, in this embodiment, the hinge assembly 300 further includes two pin shafts 330. The pin shafts 330 are detachably and rotatably inserted between the first movable seat 310 and the second movable seat 320. A pin block 331 is movably inserted at the free end of the pin shaft 330, and a screw is screwed at the free end of the pin shaft 330 to fix the pin block 331 at the free end of the pin shaft 330, so as to realize that the pin shaft 330 can be detachably installed between the first movable seat 310 and the second movable seat 320. When it is necessary to disassemble the hinge assembly 300 to separate the two core barrels 240, the screw can be disassembled first to remove the pin block 331, and then the pin shaft 330 is pulled out, so as to disassemble the first movable seat 310 and the second movable seat 320 on the hinge assembly 300, and further achieve the effect of separating the two core barrels 240.

[0062] As Figure 4 shown, in this embodiment, a U-shaped frame 211 sleeved with the hook of the electric hoist 420 is fixed on the top of the carrier plate 210, so that when the electric hoist 420 lifts the hook, the U-shaped frame 211 can be lifted, and then the entire drilling mechanism 200 can be lifted to pull out the core barrel 240. When the electric hoist 420 lowers the hook, the drilling mechanism 200 can automatically fall along the guide post 110 under the action of its own gravity. Among them, the electric hoist 420 is an existing technical device, and the specific suspension principle will not be elaborated in detail.

[0063] In this embodiment, combining Figure 9 , a circular hole is formed in the middle of the top surface of the base plate 100, and the circular hole facilitates multiple core barrels 240 to pass through and then drill into the ground.

[0064] As Figure 2 andFigure 4 As shown, in this embodiment, a plurality of limiting grooves 411 are provided on the outer sides of both ends of the bracket 410. One end of the towing rope 430 is detachably hung on the connecting plate 270 of the carrier plate 210 through a hook, and the other end of the towing rope 430 is detachably sleeved on the hook of the electric hoist 420 through a collar.

[0065] In this embodiment, when it is necessary to apply the downward pressure for the drilling mechanism 200 to move downward by means of the electric hoist 420, the hook can be separated from the C-shaped frame 211, the hook is connected to the collar on the towing rope 430, and then the electric hoist 420 lifts the hook to downwardly tow the carrier plate 210 at the hook end of the towing rope 430, thereby applying a downward drilling pressure to the drilling mechanism 200.

[0066] In this embodiment, by providing a plurality of limiting grooves 411 at different positions on the outer side of the bracket 410, the inclined arrangement of the limiting grooves 411 can prevent the towing rope 430 from detaching from the bracket 410. The limiting grooves 411 at different positions facilitate the adaptive installation of the length of the towing rope 430 and the height position of the hook of the electric hoist 420, and also facilitate the control and adjustment of the distance range for the towing rope 430 to downwardly drag the drilling mechanism 200.

[0067] As Figure 9 shown, in this embodiment, the horizontal sampling member 500 further includes two shaft rods 530. The support plate 510 and the sleeve 520 are respectively fixedly connected to the corresponding shaft rods 530. The shaft rod 530 on the support plate 510 is detachably inserted and fixed to the base plate 100, the shaft rod 530 on the sleeve 520 is rotatably connected to the base plate 100, a plastic bag 521 is sleeved at the open end of the sleeve 520, and a first inserting rod 522 is movably inserted into the open end of the sleeve 520.

[0068] In this embodiment, when it is necessary to horizontally take out a fragile core, first rotate the core tube 240 by 90 degrees so that it is placed on the support plate 510, then sleeve the plastic bag 521 at the open end of the sleeve 520, and then use the supporting first inserting rod 522 to insert into the inside of the core tube 240, so that the core inside the core tube 240 is filled into the plastic bag 521. The plastic bag 521 moves the core sample into the inside of the sleeve 520, and then rotate the sleeve 520 by 180 degrees so that the opening of the plastic bag 521 faces outward, which is convenient for the user to draw out the plastic bag 521 containing the core sample from the inside of the sleeve 520.

[0069] In this embodiment, a support tube is fixed on the outer side of the sleeve 520, the support tube is fixed to the shaft rod 530, and the heights of the horizontal sampling members 500 at both ends of the base plate 100 are different, which is convenient for the core tubes 240 at different positions to be respectively rotated and laid flat for sampling in different directions, and at the same time, inserting the first inserting rod 522 into the inside of the core tube 240 will not be interfered by the sleeve 520 and the shaft rod 530.

[0070] Embodiment 2. On the basis of Embodiment 1, in order to enable multiple core barrels 240 to vertically move downward stably and rotate for drilling.

[0071] As Figure 4 shown, in this embodiment, a deviation prevention assembly 700 is provided in the middle of the substrate 100. The deviation prevention assembly 700 includes a circular ring 710 fixedly connected to the substrate 100. Two L-shaped shafts 720 are movably inserted into the top of the circular ring 710. An arc-shaped plate 730 is fixed to the top of the L-shaped shaft 720.
