Rock-soil layer drilling and exploring equipment for engineering construction

Abstract

This invention relates to the field of rock and soil exploration technology, and discloses a rock and soil drilling exploration device for engineering construction. The device includes a main body with a support frame rotatably connected inside. A drill rod is mounted on the side wall of the support frame. When two arc-shaped plates form a cross shape around the outer surface of the drill rod, the invention enhances the rotational force of the motor, causing the motor to drive the drill rod to rotate and disengage from a jammed state via a threaded shaft. After disengagement, the hydraulic rod retracts to its output end. As the hydraulic rod retracts, it resets the two arc-shaped plates, allowing them to fit onto the outer surface of the drill rod, enabling normal operation. This reduces the likelihood of the drill rod jamming when encountering harder rock layers during rotation within the rock and soil strata, thus improving the exploration quality of the device.

Description

Technical Field

[0001] This invention relates to the field of rock and soil exploration technology, specifically to a rock and soil drilling and exploration equipment for engineering construction. Background Technology

[0002] The rock and soil drilling and exploration equipment used in this project is compact and easy to move, and is suitable for various field operation scenarios. It can efficiently complete deep drilling and sampling and stratum exploration of soil, gravel and hard rock layers. It is widely used in the early geological survey of infrastructure construction, road and bridge construction, water conservancy infrastructure and other projects, and provides accurate and reliable geological data for engineering planning and design and construction scheme formulation. When using this device, the operator first moves it to the designated exploration point, connecting the internal threaded shaft to the drill rod. Then, the motor drives the drill rod to rotate via the threaded shaft, while a sliding plate moves downwards along the side wall of the support frame. This causes the drill rod to rotate rapidly at the designated exploration point while moving into the soil and rock layer, allowing it to collect soil and rock samples. These samples are then collected to achieve the purpose of soil and rock exploration. However, when the drill rod rotates and moves within the soil and rock layer, it is prone to jamming when encountering harder rock layers due to the reaction force of the rock. This affects the operation of the drill rod within the soil and rock layer and the exploration quality of the device. Summary of the Invention

[0003] The purpose of this invention is to provide a drilling and exploration device for rock and soil layers in engineering construction, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a drilling and exploration device for rock and soil layers used in engineering construction. It includes a main body, a support frame rotatably connected inside the main body, a drill rod mounted on the side wall of the support frame, a chain rotatably connected to the side wall of the support frame, and a sliding plate fixedly connected to the bottom of the chain. The device also includes: The fixing mechanism is installed on the side wall of the support frame; The fixing mechanism includes an arc-shaped spring installed on the inner wall of the main body, and a rotating plate is fixedly connected to the side wall of the arc-shaped spring; The driving mechanism is installed between several rotating plates; The pushing mechanism includes a connecting rod disposed on the side wall of the sliding component, and a fixed block is rotatably connected to the side wall of the connecting rod.

[0005] Furthermore, the main body includes: A rotating assembly is installed on the side wall of the sliding plate and is used to drive the drill rod to rotate on the support frame. The locking assembly is installed on the outer surface of the rotating assembly and is used to fix the rotating assembly when it is fitted onto the outer surface of the drill pipe.

[0006] Furthermore, the fixed mechanism includes: The shrinkage assembly is installed on the inner wall of the locking assembly and is used to shrink the drill pipe when the locking assembly fixes it. The sliding component is installed on the inner wall of the locking component and is used to slide when the shrinking component retracts.

[0007] Furthermore, the promoting organizations include: A rotating component is mounted on the side wall of the fixed block and is used to rotate when the retraction component moves. The limiting component is installed on the side wall of the locking component and is used to limit the movement of the retracting component during operation.

[0008] Furthermore, the rotating assembly includes a motor slidably connected to the side wall of the sliding plate, and the output shaft at the bottom of the motor is fixedly connected to a threaded shaft; The outer surface of the threaded shaft is threadedly connected to the inner wall of the drill rod.

[0009] Furthermore, the locking assembly includes several hydraulic rods fixedly connected to the outer surface of the threaded shaft, and the output end of the hydraulic rods is rotatably connected to an arc-shaped plate. A spherical block is rotatably connected to the top center of the arc-shaped plate, and a fixing rod is fixedly connected to the outer surface of the spherical block; There are two hydraulic rods, and the tops of the two fixed rods are fixedly connected to the outer surface of the threaded shaft. The sidewalls of several arc-shaped springs are fixedly connected to the inner wall of the arc-shaped plate, and the sidewalls of several rotating plates are rotatably connected to the sidewall of the arc-shaped plate.

[0010] Furthermore, the shrinkage assembly includes a corrugated plate rotatably connected to the side wall of the rotating plate; The wave plate is curved and retractable, with its top and bottom rotatably connected to the side wall of the rotating plate.

[0011] Furthermore, the sliding assembly includes several arc-shaped strips fixedly connected to an inner wall of the arc-shaped plate, and several sliding grooves are provided on the side walls of the arc-shaped strips; The sliding groove has a sliding block inside it; The curved strip is designed as a triangle.

[0012] Furthermore, the rotating assembly includes an arc-shaped plate 2 that is slidably connected to the side wall of the wave plate; Among them, the side wall of the arc-shaped plate 2 is rotatably connected to the side walls of several fixed blocks.

[0013] Furthermore, the limiting component includes several L-shaped blocks fixedly connected to an inner wall of the arc-shaped plate, and U-shaped strips are slidably connected inside the L-shaped blocks; The sidewalls of the U-shaped strip are provided with several stops; Among them, the U-shaped strip is slidably connected to the inner wall of the arc plate, and two stops are provided in total; The L-shaped block is positioned between the two stops.

[0014] The present invention has the following beneficial effects: (1) In this invention, when the arc plate rotates, its inner wall will fit against the outer surface of the drill rod and strengthen the connection between the drill rod and the outer surface of the threaded shaft. When the two arc plates form a cross shape around the outer surface of the drill rod, the rotational power of the motor is enhanced, so that the motor drives the drill rod to rotate through the threaded shaft to get out of the jammed state. After getting out, the hydraulic rod will retract to the output end. When the hydraulic rod output end retracts, it will drive the two arc plates to reset, thereby fitting on the outer surface of the drill rod, so that the drill rod can run normally. This reduces the situation where the drill rod encounters a part of the harder rock layer when it rotates and moves inside the rock and soil layer, and thus gets jammed due to the reaction force of the rock layer. This allows the drill rod to run smoothly inside the rock and soil layer, improving the exploration quality of the device when conducting rock and soil layer exploration.

[0015] (2) In the process of the corrugated plate shrinking, its inner wall will shrink and fit against the outer surface of the drill rod. At this time, the rotating plate on the other side connected to the corrugated plate will rotate towards the drill rod under the push of the shrinking corrugated plate, thereby pulling the arc spring to extend and accumulate potential energy. Under the deformation of several rotating plates and the corrugated plate, the contact area between the outer surface of the drill rod and the corrugated plate on the inner wall of the arc plate will increase, so that the arc plate can better fix the drill rod on the outer surface of the threaded shaft. This reduces the situation where the drill rod is locked by the rotating plate through the side, resulting in indentations on the outer surface of the drill rod. This ensures the flatness of the outer surface of the drill rod and improves the exploration efficiency of the device when conducting rock and soil exploration.

[0016] (3) In this invention, when the sliding block slides to both ends of the sliding groove, it will be blocked and fixed by the side of the sliding groove, thereby limiting the rotation amplitude of the wave plate when it pushes the arc plate two to rotate. This enables the auxiliary rotating plate to push the wave plate to contract when the arc plate one rotates and drives the rotating plate to contact the outer surface of the drill rod. This reduces the situation where the wave plate cannot be reset due to excessive contraction caused by the large rotation amplitude of the rotating plate when it is rotated by the counter-thrust of the drill rod and pushes the wave plate to contract and tilt. This limits the contraction amplitude of the wave plate and the arc spring, and further improves the exploration quality of the device when conducting rock and soil exploration.

[0017] (4) In the process of the U-shaped strip moving, its side wall will push another rotating plate to rotate in the direction of the drill rod, thereby stretching the arc spring connected to it. When the two rotating plates rotate to different degrees, they will drive the wave plate to tilt, so that the inner wall of the wave plate can better fit with the outer surface of the drill rod. This reduces the situation where the rotating plate swings less, resulting in a smaller thrust on the other rotating plate that cannot drive the wave plate to tilt when the rotating plate contacts the drill rod and the drill rod applies a reverse force to the rotating plate. This ensures the operation of the rotating plate and the wave plate and further improves the exploration efficiency of the device when conducting rock and soil exploration.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8 As shown, the present invention is a drilling and exploration device for rock and soil layers in engineering construction, comprising a main body 1, a support frame 101 rotatably connected inside the main body 1, a drill rod 102 provided on the side wall of the support frame 101, a chain 111 rotatably connected to the side wall of the support frame 101, a sliding plate 112 fixedly connected to the bottom of the chain 111, and further comprising: Fixing mechanism 2 is installed on the side wall of support frame 101; The fixing mechanism 2 includes an arc spring 211 installed on the inner wall of the main body 1, and a rotating plate 212 is fixedly connected to the side wall of the arc spring 211. A driving mechanism 3 is installed between several rotating plates 212; The pushing mechanism 3 includes a connecting rod 311 disposed on the side wall of the sliding assembly 22, and a fixing block 312 is rotatably connected to the side wall of the connecting rod 311.

[0024] Entity 1 includes: Rotating assembly 11 is mounted on the side wall of sliding plate 112 and is used to drive drill rod 102 to rotate on support frame 101; Locking assembly 12 is installed on the outer surface of rotating assembly 11 and is used to fix rotating assembly 11 when it is sleeved on the outer surface of drill rod 102.

[0025] Fixed mechanism 2 includes: The shrinking component 21 is installed on the inner wall of the locking component 12 and is used to shrink when the locking component 12 fixes the drill pipe 102. The sliding component 22 is installed on the inner wall of the locking component 12 and is used to slide when the retraction component 21 retracts.

[0026] The driving body 3 includes: Rotating component 31 is mounted on the side wall of fixed block 312 and is used to rotate when retracting component 21 moves; Limiting component 32 is installed on the side wall of locking component 12 and is used to limit the retraction component 21 during operation.

[0027] The rotating assembly 11 includes a motor 113 that is slidably connected to the side wall of the sliding plate 112, and the output shaft at the bottom of the motor 113 is fixedly connected to a threaded shaft 114; The outer surface of the threaded shaft 114 is threadedly connected to the inner wall of the drill rod 102. When the threaded shaft 114 moves downward, it will contact the inner wall of the drill rod 102. At this time, the motor 113 will drive the threaded shaft 114 to rotate, thereby making the threaded shaft 114 threadedly connected to the drill rod 102. Then, the motor 113 drives the drill rod 102 to rotate through the threaded shaft 114 and the sliding plate 112 moves downward on the side wall of the support frame 101.

[0028] The locking assembly 12 includes a plurality of hydraulic rods 121 fixedly connected to the outer surface of the threaded shaft 114, and the output end of the hydraulic rods 121 is rotatably connected to an arc-shaped plate 122. A spherical block 123 is rotatably connected to the top center of the arc plate 122, and a fixing rod 124 is fixedly connected to the outer surface of the spherical block 123. Two hydraulic rods 121 are provided, and the tops of the two fixed rods 124 are fixedly connected to the outer surface of the threaded shaft 114. The sidewalls of several arc-shaped springs 211 are fixedly connected to the inner wall of the arc-shaped plate 122, and the sidewalls of several rotating plates 212 are rotatably connected to the sidewalls of the arc-shaped plate 122. When the threaded shaft 114 moves downward under the drive of the sliding plate 112, the threaded shaft 114 will drive the hydraulic rod 121 and the fixed rod 124 on the outer surface to move downward. When the fixed rod 124 and the hydraulic rod 121 move downward, they will drive the two arc-shaped plates 122 at the bottom to move to the outer surface of the drill rod 102.

[0029] The shrinkage assembly 21 includes a corrugated plate 213 rotatably connected to the side wall of the rotating plate 212; The wave plate 213 is generally arc-shaped and retractable. The top and bottom of the wave plate 213 are rotatably connected to the side wall of the rotating plate 212. When the arc plate 122 is pushed by the output end of the hydraulic rod 121 and rotates on the outer surface of the arc plate 122, it will drive several rotating plates 212 inside to move. When the rotating plates 212 move, they will drive the wave plate 213 connected to them to move and contact the outer surface of the drill rod 102.

[0030] The sliding component 22 includes a plurality of arc-shaped strips 221 fixedly connected to the inner wall of the arc-shaped plate 122, and a plurality of sliding grooves 222 are provided on the side wall of the arc-shaped strips 221; The sliding groove 222 is internally connected to a sliding block 223; The arc-shaped strip 221 is triangular in shape. When the connecting rod 311 is pushed, it will exert a pushing force on the sliding block 223 on the side wall, causing the sliding block 223 to slide inside the sliding groove 222. When the sliding block 223 slides to both ends of the sliding groove 222, it will be blocked and fixed by the side of the sliding groove 222, thereby limiting the rotation amplitude of the arc-shaped plate 122 when the wave plate 213 pushes it to rotate.

[0031] Rotating assembly 31 includes an arc-shaped plate 313 that is slidably connected to the side wall of the wave plate 213; Among them, the side wall of the arc plate 313 is rotatably connected to the side wall of several fixed blocks 312. When the arc plate 313 rotates, it will be guided by the inclined surface of the arc strip 221 on its outer wall to rotate. During the rotation of the arc plate 313, the fixed blocks 312 will apply a thrust to the connecting rod 311.

[0032] The limiting component 32 includes a plurality of L-shaped blocks 321 fixedly connected to the inner wall of the arc plate 122, and a U-shaped strip 322 is slidably connected inside the L-shaped blocks 321; The side wall of the U-shaped strip 322 is provided with several blocks 323; Among them, the U-shaped strip 322 is slidably connected to the inner wall of the arc plate 122, and two blocks 323 are provided in total; The L-shaped block 321 is positioned between the two stops 323. After being pushed on one side of the U-shaped bar 322, it will move inside the L-shaped block 321 toward the other rotating plate 212. During the movement of the U-shaped bar 322, its sidewall will push the other rotating plate 212 to rotate toward the drill rod 102, thereby stretching the arc spring 211 connected to it.

[0033] In operation, the operator first moves the main body 1 to the designated exploration point. Then, the support frame 101 is positioned perpendicular to the ground. At this point, the sliding plate 112 moves upward on the support frame 101 via the rotation of the chain 111. The operator then places the drill rod 102 at the bottom of the sliding plate 112, and subsequently moves the sliding plate 112 downward on the support frame 101 via the chain 111. As the sliding plate 112 moves downward, it drives the motor 113 on the side wall and the threaded shaft 114 at the bottom of the motor 113 downward. When the threaded shaft 114 moves downward, it contacts the inner wall of the drill rod 102. At this time, the motor 113 will drive the threaded shaft 114 to rotate, thereby connecting the threaded shaft 114 to the drill rod 102. Then, the motor 113 drives the drill rod 102 to rotate through the threaded shaft 114, and the sliding plate 112 moves downward on the side wall of the support frame 101, so that the drill rod 102 moves into the soil and rock layer while rotating rapidly at the designated exploration point. This allows the drill rod 102 to collect soil and rock samples from inside the soil and rock layer. After the drill rod 102 has completed the collection of the samples, the motor 113 drives the threaded shaft 114 to disengage from the drill rod 102, and then collects the soil and rock samples inside the drill rod 102 to achieve the purpose of exploring the soil and rock layer.

[0034] When the threaded shaft 114 moves downward under the influence of the sliding plate 112, the threaded shaft 114 will drive the hydraulic rod 121 and the fixed rod 124 on the outer surface to move downward. When the fixed rod 124 and the hydraulic rod 121 move downward, they will drive the two arc-shaped plates 122 at the bottom to move to the outer surface of the drill rod 102. When the drill rod 102 is stuck in the soil layer, the hydraulic rod 121 will push its output shaft to move downward. When the output end of the hydraulic rod 121 moves downward, it will push the arc-shaped plate 122 connected to it to rotate downward around one side of the spherical block 123. When the arc-shaped plate 122 rotates, its inner wall will fit against the outer surface of the drill rod 102 and strengthen the connection between the drill rod 102 and the outer surface of the threaded shaft 114. When the two arc-shaped plates When the 122 plates form a cross shape around the outer surface of the drill rod 102, the rotational force of the motor 113 is increased. This causes the motor 113 to drive the drill rod 102 to rotate and disengage from the jammed state via the threaded shaft 114. After disengagement, the hydraulic rod 121 retracts to its output end. When the output end of the hydraulic rod 121 retracts, it drives the two arc-shaped plates 122 to reset, thereby fitting onto the outer surface of the drill rod 102. This allows the drill rod 102 to operate normally, reducing the possibility of the drill rod 102 getting stuck when it encounters a harder rock layer and is subjected to the reaction force of the rock layer when rotating and moving inside the soil and rock layer. This allows the drill rod 102 to operate smoothly inside the soil and rock layer, improving the exploration quality of the device when conducting soil and rock layer exploration.

[0035] When the arc-shaped plate 122 is pushed by the output end of the hydraulic rod 121 to rotate on its outer surface, it will drive several internal rotating plates 212 to move. When the rotating plates 212 move, they will drive the corrugated plates 213 connected to them to move and contact the outer surface of the drill rod 102. Then, under the continuous rotation of the arc-shaped plate 122, the rotating plates 212 will be subjected to the reverse force of the outer surface of the drill rod 102 and will rotate to one side in the direction of the arc-shaped plate 122. At the same time, the rotating plates 212 will push the arc-shaped spring 211 connected to them to contract and accumulate potential energy. When the rotating plates 212 rotate in the direction of the arc-shaped plate 122, they will push the corrugated plates 213 connected to them to contract as a whole. During the contraction of the corrugated plates 213, their inner walls will close up and fit against the outer surface of the drill rod 102. At this time, the rotating plate 212 on the other side connected to the corrugated plate 213 will rotate towards the drill rod 102 under the push of the contracting corrugated plate 213, thereby pulling the arc spring 211 to extend and accumulate potential energy. Under the deformation of several rotating plates 212 and corrugated plates 213, the contact area between the outer surface of the drill rod 102 and the corrugated plate 213 on the inner wall of the arc plate 122 will increase. This allows the arc plate 122 to better fix the drill rod 102 to the outer surface of the threaded shaft 114, reducing the occurrence of indentations on the outer surface of the drill rod 102 due to the rotating plate 212 fixing the drill rod 102 by the side during the process of locking the drill rod 102 by rotating the arc plate 122. This ensures the flatness of the outer surface of the drill rod 102 and improves the exploration efficiency of the device when conducting rock and soil exploration.

[0036] When the wave plate 213 rotates slightly due to the counter-thrust from the outer surface of the drill rod 102, it slides on the inner wall of the arc plate 122, causing the arc plate 213 on its inner wall to rotate. During this rotation, the arc plate 213 is guided by the inclined surface of its outer arc strip 221. As the arc plate 213 rotates, it applies a thrust to the connecting rod 311 via the fixing block 312. After receiving this thrust, the connecting rod 311 applies a thrust to the sliding block 223 on the side wall, causing the sliding block 223 to slide inside the sliding groove 222. When the sliding block 223 slides to both ends of the sliding groove 222, it is subjected to a sliding... The obstruction on the side of the moving groove 222 is fixed, thereby limiting the rotation amplitude of the second arc plate 313 when the wave plate 213 pushes it to rotate. This allows the rotating plate 212 to assist the wave plate 213 in contracting when the rotating plate 212 contacts the outer surface of the drill rod 102. This reduces the possibility of the wave plate 213 becoming over-contracted and unable to return to its original position due to excessive rotation amplitude caused by the large rotation amplitude of the rotating plate 212 during the process of the rotating plate 212 being rotated by the counter-thrust force of the drill rod 102 and pushing the wave plate 213 to contract and tilt. This limits the contraction amplitude of the wave plate 213 and the arc spring 211, further improving the exploration quality of the device when conducting rock and soil exploration.

[0037] As one rotating plate 212 rotates towards the arc-shaped plate 122 under the counter-thrust of the drill rod 102, one of the rotating plates 212 rotates towards the arc-shaped plate 122 and pushes the arc-shaped spring 211 on its inner wall to contract. During the rotation of this rotating plate 212, it applies a thrust to the U-shaped strip 322 on the inner wall. After being pushed on one side, the U-shaped strip 322 moves towards the other rotating plate 212 inside the L-shaped block 321. During the movement of the U-shaped strip 322, its side wall pushes the other rotating plate 212 to rotate towards the drill rod 102, thereby stretching the arc-shaped spring 211 connected to it. Spring 211, when the two rotating plates 212 rotate to different degrees, will cause the corrugated plate 213 to tilt, so that the inner wall of the corrugated plate 213 can better fit with the outer surface of the drill rod 102. This reduces the situation where, when the rotating plate 212 contacts the drill rod 102 and the drill rod 102 applies a reverse force to the rotating plate 212, the smaller swing amplitude of the rotating plate 212 results in a smaller thrust on the other rotating plate 212, which cannot tilt the corrugated plate 213. This ensures the operation of the rotating plate 212 and the corrugated plate 213, and further improves the exploration efficiency of the device when conducting rock and soil exploration.
