Description

Technical Field

[0001] This invention relates to the field of petroleum exploration technology, and in particular to a soil layer surveying device for petroleum drilling engineering surveying. Background Technology

[0002] In the early exploration and geological assessment of oil drilling projects, soil layer surveying is a key step in obtaining underground soil and rock mechanical parameters, classifying the stratigraphic structure, and assessing the bearing capacity of the foundation. Static cone penetration test (CPPT), as a widely used in-situ testing technique, involves pressing a cone probe into the soil layer at a constant rate and measuring the cone tip resistance and sidewall friction in real time. This allows for the efficient and continuous acquisition of depth profile data reflecting the properties of the soil layer, providing important scientific basis for drilling platform site selection, wellbore structure design, and construction safety assessment.

[0003] However, existing mainstream static cone penetration testing equipment has obvious limitations during operation. When a single probe reaches the end, the equipment must be stopped, and the operator must manually move, align, and tighten the next probe to extend the drill string. This process is not only labor-intensive and requires a high level of experience from the operator, but also leads to frequent interruptions in the operation, affecting the overall efficiency and continuity of exploration operations. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a soil surveying device for oil drilling engineering to solve the problems of high labor intensity and low work efficiency caused by the reliance on manual operation for loading, unloading and connecting probes in existing static cone penetration testing equipment.

[0005] To achieve the above objectives, the present invention provides a soil surveying device for oil drilling engineering, comprising a main frame and further comprising: Hydraulic telescopic rods are symmetrically and vertically fixed to the main frame; The lifting drive frame is fixed to the top of the telescopic end of the hydraulic telescopic rod; The insert clamping cylinder is located in the middle of the lifting drive frame, with open ends at the top and bottom for the probe rod to pass through; An auxiliary loading and unloading mechanism is located above the penetrating clamping cylinder; The auxiliary loading and unloading mechanism includes a loading and unloading sleeve that is coaxially arranged with the penetrating clamping cylinder; The loading and unloading sleeve is coaxially rotatably connected to a rotary drive ring, and the rotary drive ring is connected to a drive component that drives its rotation. The rotating drive ring has multiple horizontal guide sleeves evenly arranged along the circumference. Each horizontal guide sleeve has a horizontal guide rod slidably nested inside it. The inner end of the horizontal guide rod is connected to an arc-shaped clamping plate that can slide axially to clamp the probe rod, and the outer end is provided with a limiting ball. The loading and unloading sleeve is fitted with an axially sliding top-pressure clamping block, and the inner side of the top-pressure clamping block is provided with a top-pressure inclined surface that contacts the limiting ball. The top pressure drive unit has a loading and unloading sleeve and a top pressure clamping block connected at both ends, which is used to drive the top pressure clamping block to move axially so as to squeeze or release the limiting ball through the top pressure inclined surface, thereby driving all the arc-shaped clamping plates to move radially synchronously to clamp or release the probe.

[0006] Furthermore, the top-pressing drive component is an electric push rod that is vertically and parallel to the loading and unloading sleeve. The fixed end of the electric push rod is fixedly connected to the loading and unloading sleeve, and its telescopic end is fixedly connected to the top-pressing clamping block. A horizontal spring is sleeved on the horizontal guide rod, and the two ends of the horizontal spring abut against the bearing structure of the horizontal guide sleeve and the limiting ball, respectively. The loading and unloading sleeve is provided with a tapered guide port and a loading and unloading opening at its upper and lower ends, respectively. The probe is inserted into the loading and unloading sleeve through the tapered guide port and the loading and unloading opening for loading and unloading.

[0007] Furthermore, a positive clamping ring is provided on the inner side of the penetrating clamping cylinder, and a plurality of clamping blocks are uniformly arranged around the inner side of the positive clamping ring in the circumferential direction. The outer end of each clamping block is rotatably connected to the positive clamping ring through a support shaft, and the inner end is provided with a contact clamping surface facing the axis of the penetrating clamping cylinder. Clamping teeth are provided on the contact clamping surface. The clamping block is inclined downward about the support axis, and a clamping spring is provided between it and the positive clamping ring to keep the clamping block in an inclined state. The forward clamping ring, clamping block, supporting pivot, and clamping spring constitute a self-locking clamping structure. When the penetrating clamping cylinder drives the forward clamping ring to move downward, the self-locking clamping structure can clamp the probe rod; when it moves upward, it releases the probe rod.

[0008] Furthermore, a reverse clamping ring is coaxially disposed above the forward clamping ring; The inner side of the reverse clamping ring is uniformly surrounded by a plurality of clamping blocks with the same structure as the clamping blocks on the forward clamping ring but with the opposite inclination direction, so that the clamping blocks on the forward clamping ring and the reverse clamping ring are vertically symmetrical and have opposite inclination directions. An axially sliding annular adjusting block is provided between the forward clamping ring and the reverse clamping ring, and synchronous pressing blocks are symmetrically provided on the top and bottom surfaces of the annular adjusting block. The annular adjusting block is configured such that when it slides downward, the synchronous pressing block at its bottom can press the clamping block on the forward clamping ring to flip downward; and when it slides upward, the synchronous pressing block at its top can press the clamping block on the reverse clamping ring to flip upward.

[0009] Furthermore, the annular adjusting block is slidably connected to the penetrating clamping cylinder along the axial direction, and an adjusting return spring is provided below it; An extension adjustment block is connected to the outer side of the annular adjustment block, and a fitting adjustment groove is provided in the middle of the extension adjustment block. An adjustment cam is provided on the inner side of the fitting adjustment groove. A connecting shaft is horizontally provided at the center of the adjustment cam and is rotatably connected to the penetrating clamping cylinder through the connecting shaft. An adjustment handle is connected to the outer end of the connecting shaft.

[0010] Furthermore, a conical guide cylinder is provided above the loading and unloading sleeve, a horizontal conveying frame is provided on the outer side of the top opening of the conical guide cylinder, a circulating conveying chain is provided in the middle of the horizontal conveying frame, and multiple limiting conveying frames are uniformly arranged around the outer side of the circulating conveying chain in the circumferential direction, and an arc-shaped fitting conveying groove is provided in the middle of each limiting conveying frame. The inner side of the circulating conveyor chain is engaged with a conveyor sprocket, which drives the circulating conveyor chain to move all the limit conveyor frames synchronously. The probe rod placed in the fitting conveying groove is conveyed to the top opening of the conical guide cylinder by the limiting conveying frame, and gradually changes from a horizontal state to a vertical state under the guidance of the conical guide cylinder. The vertical probe rod falls into the inner side of the loading and unloading sleeve through the bottom opening of the conical guide cylinder, and is further conveyed downward to the penetration clamping cylinder, realizing the continuous automatic conveying of the probe rod.

[0011] Furthermore, the tapered guide cylinder is symmetrically provided with downwardly inclined limiting side plates on the left and right sides. After the probe enters the tapered guide cylinder, it changes from a horizontal state to a vertical state under the guidance of the limiting side plates. The top end of the limiting side plate is rotatably connected to the top end of the conical guide cylinder via a side plate pivot. A telescopic push rod is connected to the outer side of the limiting side plate, and the two ends of the telescopic push rod are rotatably connected to the limiting side plate and the main frame, respectively. The telescopic push rod drives the limiting side plate to rotate upward around the side plate axis, thereby changing the probe rod located in the conical guide cylinder from a vertical state to a horizontal state and lifting and conveying it to the top opening of the conical guide cylinder, and then transferring it to the horizontal conveyor frame to achieve continuous retrieval of the probe rod.

[0012] Furthermore, it also includes: The probe storage box has multiple horizontal conveyor racks arranged in parallel vertical directions inside; Each horizontal conveyor frame is surrounded by a circulating conveyor chain and multiple limiting conveyor frames connected to it. The top opening of the conical guide tube is located at the outer end of the topmost horizontal conveyor frame; An arc-shaped guide frame is provided between the outer ends of adjacent horizontal conveyor frames. When the probe is conveyed, it moves between adjacent horizontal conveyor frames along the arc-shaped guide frame. Each conveyor sprocket has a synchronous gear connected to its shaft end. The synchronous gears of adjacent horizontal conveyor frames mesh with each other, and a conveyor motor is connected to the shaft end of one of the synchronous gears. Driven by the conveyor motor, the conveyor sprockets of adjacent horizontal conveyor frames rotate synchronously in opposite directions via the transmission of synchronous gears, thereby driving the circulating conveyor chain on it to move synchronously with the limiting conveyor frame, realizing multi-layer storage and continuous conveying of probes in the probe storage box.

[0013] Furthermore, a guide cleaning sleeve is coaxially fixedly installed below the penetrating clamping cylinder. The guide cleaning sleeve is fixedly connected to the main frame. An annular conveying pipe is arranged around the bottom inner side of the guide cleaning sleeve. Multiple flushing nozzles are arranged circumferentially on the inner side of the annular conveying pipe. A rotating connecting frame is coaxially rotatably connected to the middle inner side of the guide cleaning sleeve. A spiral cleaning brush is arranged around the inner side of the rotating connecting frame.

[0014] Furthermore, multiple connecting rocker arms are evenly arranged around the inner top of the rotating connecting frame in the circumferential direction. The outer end of each connecting rocker arm is rotatably connected to the rotating connecting frame, and the inner end is rotatably connected to a guide roller. A buffer spring is provided in the middle of the connecting rocker arm to provide elastic force so that the guide roller maintains a radially inward pressing tendency. The guide roller and the connecting rocker arm are set at an inclined angle to the axis of the guide cleaning sleeve.

[0015] As can be seen from the above, the soil layer surveying device for oil drilling engineering provided by the present invention has the following beneficial effects: 1. It achieves continuous operation throughout the entire process. The device integrates the functions of automatic supply of probe rods, threaded connection, uniform speed penetration, segmented extraction, and automatic retrieval and storage, forming a complete closed-loop operation process. This reduces the heavy physical labor and work interruptions such as frequent manual handling, alignment, and tightening in traditional exploration, and significantly improves the efficiency of daily operations. 2. The adaptive self-locking clamping mechanism can automatically adjust the clamping force according to the formation resistance to ensure that the probe does not slip or come off during the penetration and extraction process. The bidirectional clamping function enables the device to have reliable power transmission and load holding capabilities in both the pressing and pulling directions. 3. The built-in guide cleaning sleeve can automatically brush off the dirt adhering to the surface of the probe rod during its up and down movement, keeping the probe rod clean, extending the service life of the equipment, and facilitating the recovery and storage of the probe rod.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1 to 10As shown, a soil surveying device for oil drilling engineering includes a main frame 1, and further includes: The hydraulic telescopic rod 101 is symmetrically and vertically fixed to the main frame 1; The lifting drive frame 102 is fixed to the top end of the telescopic end of the hydraulic telescopic rod 101; Insert the clamping cylinder 2, which is located in the middle of the lifting drive frame 102. Its upper and lower ends are open for clamping and for the probe rod 10 to pass through. An auxiliary loading and unloading mechanism is located above the penetrating clamping cylinder 2; The auxiliary loading and unloading mechanism includes a loading and unloading sleeve 5 that is coaxially arranged with the penetrating clamping cylinder 2; A rotary drive ring 6 is coaxially rotatably connected inside the loading and unloading sleeve 5. The rotary drive ring 6 is driven to rotate by a drive component. The rotating drive ring 6 has a plurality of horizontal guide sleeves 602 evenly arranged along the circumference of the ring body. Each horizontal guide sleeve 602 has a horizontal guide rod 606 slidably nested inside it. The inner end of the horizontal guide rod 606 is connected to an arc-shaped clamping plate 604 that can slide axially for clamping the probe rod 10, and the outer end is provided with a limiting ball 607. The outer side of the loading and unloading sleeve 5 is fitted with an axially sliding top pressure clamping block 503, and the inner side of the top pressure clamping block 503 is provided with a top pressure inclined surface 504 that contacts the limiting ball 607. The top pressure drive is connected to the loading and unloading sleeve 5 and the top pressure clamping block 503 at both ends, respectively. It is used to drive the top pressure clamping block 503 to move axially so as to squeeze or release the limiting ball 607 through the top pressure inclined surface 504, thereby driving all the arc-shaped clamping plates 604 to move radially synchronously to clamp or release the probe rod 10.

[0022] In this embodiment, the device mainly includes a main frame 1, a hydraulic telescopic rod 101, a lifting drive frame 102, a penetration clamping cylinder 2, and an auxiliary loading and unloading mechanism. The hydraulic telescopic rod 101 is symmetrically and vertically fixed on the main frame 1. The lifting drive frame 102 is fixed to the top end of the telescopic end of the hydraulic telescopic rod 101 and can move up and down with the telescopic movement of the hydraulic telescopic rod 101. The penetration clamping cylinder 2 is located in the middle of the lifting drive frame 102, and both its upper and lower ends are open structures for clamping the probe 10 and allowing the probe 10 to pass through it. The auxiliary loading and unloading mechanism is located above the penetration clamping cylinder 2. This mechanism includes a loading and unloading sleeve 5 coaxially arranged with the penetration clamping cylinder 2. A rotary drive ring 6 is coaxially rotatably connected. This rotary drive ring 6 is driven to rotate by an independent drive component. Multiple horizontal guide sleeves 602 are evenly arranged circumferentially on the ring body of the rotary drive ring 6. A horizontal guide rod 606 is slidably nested within each horizontal guide sleeve 602. The inner end of the horizontal guide rod 606 is connected to an arc-shaped clamping plate 604 that can slide along the axis of the loading / unloading sleeve 5, used to directly clamp the probe rod 10. A limiting ball 607 is provided at its outer end. On the outer side of the loading / unloading sleeve 5, a top-pressure clamping block 503 that can slide axially is fitted. The inner side of the top-pressure clamping block 503 has a top-pressure inclined surface 504 that contacts the aforementioned limiting ball 607. The two ends of the pressure drive are respectively connected to the loading and unloading sleeve 5 and the top pressure clamping block 503, which is used to drive the top pressure clamping block 503 to move axially. When the top pressure drive pushes the top pressure clamping block 503 to move, the top pressure inclined surface 504 on its inner side will squeeze each limiting ball 607, thereby pushing all the horizontal guide rods 606 to drive the arc-shaped clamping plate 604 to move radially towards the center in sync, thus clamping the probe 10. Conversely, when the top pressure clamping block 503 moves in the opposite direction to release the squeezing of the limiting ball 607, the arc-shaped clamping plate 604 moves radially outward under the action of the horizontal spring 603, thereby releasing the probe 10. After the arc-shaped clamping plate 604 clamps the probe 10, the drive component drives the rotation. The drive ring 6 rotates, and the rotation of the drive ring 6 drives the probe rod 10 to rotate through the clamped arc-shaped clamping plate 604 and the horizontal guide rod 606, thereby facilitating the connection and disassembly of the probe rod 10's threaded ends and completing the automatic docking of the probe rod 10. The arc-shaped clamping plate 604 and the horizontal guide rod 606 are slidably connected along the axis of the loading and unloading sleeve 5, so that during the connection process, the clamping mechanism can follow the probe rod 10 to make appropriate axial movements, avoiding rigid interference. The sliding return spring 605 connected on the arc-shaped clamping plate 604 can automatically pull the arc-shaped clamping plate 604 back to the initial position after the clamping action is released. In addition, a reaction structure is provided on the main frame 1 of the device.The reaction structure includes multiple ground anchors 103, each with a spiral plate at its bottom. A motor at the top of the ground anchor 103 drives it to rotate, thereby screwing the ground anchor 103 into the underground soil layer. This provides stable fixation and reaction support for the entire device during surveying operations. Through the auxiliary loading and unloading mechanism, the device can automatically complete the clamping, rotating docking, and releasing operations of the probe rod 10, which helps to reduce the labor intensity of manual operation and improve the continuity of probe rod 10 connection operations.

[0023] like Figures 1 to 10 As shown, preferably, the top-pressing drive component of the auxiliary loading and unloading mechanism of the device is an electric push rod 505 that is vertically and parallel to the loading and unloading sleeve 5. The two ends of the electric push rod 505 are fixedly connected to the outer wall of the loading and unloading sleeve 5 and the top-pressing clamping block 503, respectively. A horizontal spring 603 is also fitted in the middle section of the horizontal guide rod 606. The upper and lower ends of the loading and unloading sleeve 5 are respectively formed with a tapered guide opening 501 and a loading and unloading opening 502. When loading and unloading the probe 10, the probe 10 is inserted into or removed from the loading and unloading sleeve 5 through the upper tapered guide opening 501 and the lower loading and unloading opening 502 in sequence. When it is necessary to clamp the probe 10, the electric push rod 505 is activated, driving the top pressure clamping block 503 to move downward along the axial direction of the loading and unloading sleeve 5. During the downward movement, the top pressure inclined surface 504 on the inner side of the top pressure clamping block 503 squeezes each limiting ball 607, thereby pushing all the horizontal guide rods 606 to overcome the force of the horizontal spring 603 and slide synchronously inward along the radial direction. Ultimately, the arc-shaped clamping plates 604 connected to the inner end of the horizontal guide rod 606 converge towards the center, clamping the probe rod 10 located at the center of the sleeve. To achieve rotational drive, a drive gear ring 601 is fixedly fixed around the outside of the rotational drive ring 6. A drive gear 506 meshes with the outside of the drive gear ring 601. The shaft end of the drive gear 506 is connected to the output shaft of a loading / unloading drive motor 507, which is fixedly mounted on the loading / unloading sleeve 5. After the arc-shaped clamping plates 604 clamp the probe rod 10, the loading / unloading drive motor 507 is started, driving the drive gear 506 to rotate. This, in turn, drives the entire rotational drive ring 6 to rotate through the meshing drive gear ring 601. The rotation of the rotational drive ring 6 is transmitted to the clamped probe rod 10 through the horizontal guide rod 606 and the arc-shaped clamping plates 604 constrained by it, driving the probe rod 10 to rotate, thereby completing the threaded connection or disassembly operation between the probe rods 10.

[0024] like Figures 1 to 10As shown, preferably, the device has a self-locking clamping structure inside the insertion clamping cylinder 2. This structure mainly includes a positive clamping ring 4 fixed to the inner side of the insertion clamping cylinder 2. Multiple clamping blocks 402 are evenly arranged circumferentially around the inner side of the positive clamping ring 4. The outer end of each clamping block 402 is rotatably connected to the positive clamping ring 4 via a supporting rotating shaft 405, allowing it to rotate around the shaft at a certain angle. The inner end of the clamping block 402 has a contact clamping surface 403 facing the axis of the insertion clamping cylinder 2. Clamping teeth 404 are machined on the contact clamping surface 403 to enhance the engagement with the probe rod 10 surface. All clamping blocks 402 are arranged in a downward tilted manner in their natural state. A clamping spring 406 is provided between the positive clamping ring 4 and the clamping block 402. The force of the spring keeps the clamping block 402 in its initial tilted state. The positive clamping ring 4, the clamping block 402, the support shaft 405, and the clamping spring 406 together constitute the self-locking clamping structure. Its working principle is closely coupled with the movement direction of the penetrating clamping cylinder 2. When the hydraulic telescopic rod 101 drives the lifting drive frame 102 and drives the penetrating clamping cylinder 2 to move downward, the positive clamping ring 4 moves downward synchronously. At this time, the reaction force of the probe rod 10 acting on the clamping block 402 contacting the clamping surface 403 will drive each clamping block 402 to rotate upward around its support shaft 405, that is, to rotate in a direction more perpendicular to the axis of the probe rod 10, so that the clamping teeth 40 4. The probe 10 is gripped more tightly onto the surface of the probe rod 10, thus achieving self-locking clamping. During this process, the greater the axial penetration resistance from the stratum on the probe rod 10, the greater the reaction force acting on the contact clamping surface 403. Consequently, the flipping torque and clamping force generated by the clamping block 402 also increase synchronously, forming an adaptive locking effect where the resistance and clamping force increase simultaneously. Conversely, when the hydraulic telescopic rod 101 drives the entire penetrating clamping cylinder 2 to move upward, the forward clamping ring 4 drives the clamping block 402 to move upward synchronously. At this time, the direction of the force exerted by the probe rod 10 on the contact clamping surface 403 changes, which will drive the clamping block 402 to flip downward around the support shaft 405, that is, to a direction more inclined to the axis of the probe rod 10, thereby overcoming the force of the clamping spring 406. The clamping teeth 404 disengage from the probe rod 10, releasing the probe rod 10. The hydraulic telescopic rod 101 drives the lifting drive frame 102 and the penetration clamping cylinder 2 in a regular reciprocating lifting motion. Combined with the self-locking clamping structure's automatic clamping during descent and automatic release during ascent, the probe rod 10 can be cyclically and continuously pressed into the ground in segments to complete the exploration operation. Thus, the self-locking clamping structure combines the penetration direction with the clamping action. During the pressing process, the formation resistance is directly converted into mechanical benefits that enhance the clamping force of the clamping block 402, allowing the clamping force to increase adaptively with the penetration resistance. This effectively prevents the probe rod 10 from slipping or disengaging during penetration, resulting in high clamping reliability.Simultaneously, the switching between clamping and releasing relies entirely on the up-and-down movement of the insertion clamping cylinder 2 itself and the ingenious lever flipping design. This eliminates the need for a separate, complex active control drive source for the clamping action, simplifying the system and reducing control complexity. Furthermore, the action logic is reliable, and this self-locking clamping structure works in conjunction with the aforementioned auxiliary loading and unloading mechanism, making the entire operation process of clamping insertion, releasing and resetting, and re-insertion of the connecting rod highly automated and continuous. This significantly reduces operation interruptions and manual intervention, improving the overall efficiency of deep exploration.

[0025] like Figures 1 to 10As shown, preferably, the device has a reverse clamping ring 401 coaxially arranged above the forward clamping ring 4 within the clamping cylinder 2. The inner side of the reverse clamping ring 401 also has multiple clamping blocks 402 evenly arranged circumferentially. The basic structure of these clamping blocks 402 is the same as that of the clamping blocks 402 on the forward clamping ring 4, but their tilt direction in their natural state is opposite to that of the clamping blocks 402 on the forward clamping ring 4. Therefore, the two sets of clamping blocks 402 on the forward clamping ring 4 and the reverse clamping ring 401 are arranged symmetrically in space with mirror images of each other in their initial tilt directions. Within the annular space between the forward clamping ring 4 and the reverse clamping ring 401, an annular adjusting block 3 that can slide along the axis of the clamping cylinder 2 is provided. The annular adjustment block 3 is slidably connected to the inner wall of the penetrating clamping cylinder 2. An adjustment and reset spring 302 is located below it. Symmetrically arranged at the top and bottom of the annular adjustment block 3 are upwardly and downwardly protruding synchronous pressure blocks 301. The clamping block 402 on the reverse clamping ring 401 is designed to work in a mirror manner as the clamping block 402 on the forward clamping ring 401. When the reverse clamping ring 401 moves upward with the penetrating clamping cylinder 2, the reaction force of the probe 10 drives the clamping block 402 on it to flip, causing the clamping teeth 404 to bite the probe 10, thus achieving clamping. When it moves downward, it releases the probe 10. The function of the annular adjustment block 3 is to switch working modes. When it slides downward under control, the synchronous pressure block 301 at its bottom will press downward against the forward clamping ring 401. The clamping blocks 402 on the clamping ring 4 force these originally downward-sloping blocks to flip further downward, thus disengaging them from their working position and making way for the clamping action of the reverse clamping ring 401. Conversely, when the annular adjusting block 3 slides upward, the synchronous pressing block 301 at its top presses upward against the clamping blocks 402 on the reverse clamping ring 401, forcing these upward-sloping blocks to flip upward and make way, thus restoring the clamping blocks 402 of the forward clamping ring 4 to their working state. The axial sliding of the annular adjusting block 3 is driven by an adjusting mechanism. An extension adjusting block 303 is fixedly connected to the outside of the annular adjusting block 3. The extension adjusting block 303 has a fitting adjusting groove 304 in the middle, and an adjusting cam 201 is provided on the inner side of the fitting adjusting groove 304. The cylindrical outer surface of the adjusting cam 201 mates with the inner top and bottom surfaces of the fitting adjustment groove 304. A connecting shaft 202 is horizontally positioned at the center of the adjusting cam 201, through which the adjusting cam 201 is rotatably mounted on the insert clamping cylinder 2. One end of the connecting shaft 202 extends to the outside and is connected to a manual adjusting handle 203 or an adjusting motor. By manually operating the adjusting handle 203 or driving the adjusting motor, the adjusting cam 201 can be rotated around its connecting shaft 202. During rotation, the outer surface of the adjusting cam 201 will push or release the extended adjusting block 303 according to its contour, thereby driving the annular adjusting block 3 to move axially up and down against the force of the adjusting return spring 302, realizing the switching of the working position.Through the aforementioned mechanism, the operator can press in or pull out the probe 10 according to operational needs, driving the annular adjusting block 3 to slide to the corresponding position. This selectively activates the working state of the forward clamping ring 4 or the reverse clamping ring 401, enabling the device to reliably clamp the probe 10 in both downward and upward directions. The design employs a single annular adjusting block 3 in conjunction with a symmetrical synchronous pressing block 301. The axial displacement of this adjusting block alone can synchronously control the working and clearance states of the two sets of clamping blocks 402. The structure is compact, the switching action has good synchronization, and the operation is direct and rapid. By adding a symmetrical reverse clamping ring 401 and a switchable adjusting mechanism, the penetrating clamping cylinder 2 can provide self-locking clamping force not only when pressing down the probe 10 but also during the lifting and retraction of the probe 10, expanding the device's functional completeness and operational safety.

[0026] like Figures 1 to 17As shown, preferably, a conical guide cylinder 7 is coaxially fixedly installed above the loading / unloading sleeve 5. The top of the conical guide cylinder 7 is a flared horn, and its bottom opening is aligned with the upper port of the loading / unloading sleeve 5 below. A horizontal conveyor frame 801 is mounted outside the top opening of the conical guide cylinder 7. A set of circulating conveyor chains 804 is installed in the middle of the horizontal conveyor frame 801. On the outside of the circulating conveyor chain 804, multiple limiting conveyor frames 802 are evenly fixed around its circumference. Each limiting conveyor frame 802 has an arc-shaped fitting conveyor groove 803 in the middle. The shape of the groove is adapted to the outer contour of the probe rod 10 and is used to support and limit a single probe rod 10. The inner side of the circulating conveyor chain 804 is connected to one or more The conveyor sprocket 805 engages, driving the entire circulating conveyor chain 804 and all the limiting conveyor frames 802 on it to move synchronously, intermittently, or continuously along a predetermined trajectory. When conveying the probe 10, the probe 10 is placed horizontally in the arc-shaped fitting conveyor groove 803 of a limiting conveyor frame 802. In this soil surveying device, the signal cable used to connect the conical probe and the ground data acquisition system passes through the inside of the probe 10. Specifically, the data connection line starts at the conical probe, passes upwards through the hollow cavity of the first probe 10, and continues to pass through the hollow portion of each subsequent probe 10 as the probe 10 is extended, finally exiting from the top probe 10 and connecting to... The interface on the main frame 1, with this wiring method, physically forms a continuous and flexible internal central guide shaft through the data connection lines running through all probes 10. When the probes 10 are horizontally conveyed, undergo attitude changes, or fall to or rise from the working position, the internal data connection lines naturally constrain and guide the movement of the probes 10. This helps the probes 10 maintain approximate stability in their axial direction during critical transition phases, reducing unnecessary lateral swaying or angular deviations, thus providing auxiliary guidance. Therefore, as the circulating conveyor chain 804 operates, the limiting conveyor frame 802 carrying the probes 10 is moved to a suitable position directly above or to the side of the top opening of the conical guide cylinder 7, under the influence of gravity and auxiliary... Under the guidance of the auxiliary mechanism, one end of the probe 10 first contacts the inclined surface inside the conical guide cylinder 7. As the conveying continues, under the constraint and guidance of the inner wall of the conical guide cylinder 7, the probe 10 gradually changes its posture from a horizontal state to a vertical state. The lower end of the vertical probe 10 falls naturally into the inner side of the aligned loading and unloading sleeve 5 below under the action of gravity. It can be further conveyed downward to the predetermined position of penetrating the clamping cylinder 2 under the action of subsequent mechanisms. This process can realize the continuous and automatic conveying of the probe 10 to the working position. Thus, the device integrates the horizontal storage, directional conveying and posture conversion functions of the probe 10 into one, through the cooperation of the circulating conveying chain 804 and the conical guide cylinder 7.It can automatically and systematically convert the probe 10 from a horizontal to a vertical working state and transport it to the core working mechanism, significantly reducing the manual handling and loading of the probe 10, and improving the automation and continuity of the operation.

[0027] like Figures 1 to 17 As shown, preferably, downwardly inclined limiting side plates 701 are symmetrically arranged on the left and right sides of the conical guide cylinder 7. When the probe 10 is guided by the horizontal conveyor frame 801 into the top opening of the conical guide cylinder 7, its body will contact the two downwardly inclined limiting side plates 701. Under the guidance and constraint of its inclined surface, it will smoothly transition from the initial horizontal state to the vertical state, and thus fall smoothly into the loading and unloading sleeve 5 below. The top of each limiting side plate 701 is rotatably connected to the top side wall of the conical guide cylinder 7 through a side plate pivot 702, so that the limiting side plate 701 can rotate around this axis at a certain angle. On the outer side of the limiting side plate 701, i.e., the side facing away from the center of the guide cylinder, a telescopic push rod 703 is connected. The two ends of the telescopic push rod 703 are rotatably connected to the outer surface of the limiting side plate 701 and the fixed point on the main frame 1, respectively. When it is necessary to retrieve the probe 10 that has penetrated into the ground, the mechanism works in the reverse process. After the probe 10 is pulled up in sections and conveyed upward into the conical guide cylinder 7 through the loading and unloading sleeve 5, and is in a vertically suspended state, the telescopic push rods 703 on both sides extend and retract in sequence, driving the corresponding limiting side plate 701 to alternately flip upward around its side plate pivot 702. When each limiting side plate 701 flips, it supports the vertical probe 10 in the conical guide cylinder 7 from its side. As the flipping action continues, the probe 10 is gradually lifted from the vertical state and converted to a horizontal state, and finally lifted and conveyed back to the opening position at the top of the conical guide cylinder 7, from the empty space that has been moved into place on the horizontal conveyor frame 801. The limiting conveyor frame 802 receives and removes the probe rod 10. During the conveying process, the limiting side plate 701 can also form a limiting guide structure to prevent the probe rod 10 from falling prematurely and guide the conveying. Since the data connection line running through the hollow cavity of all probe rods 10 physically connects and constrains the relative position of each probe rod 10, in the retrieval state, adjacent probe rods 10 must be arranged in a parallel manner with their ends connected and opposite directions on the horizontal conveyor frame 801. That is, the probe connection end of one probe rod is adjacent to the connection end of the next probe rod. Therefore, in order to adapt to this specific arrangement direction, the limiting side plates 701 on the left and right sides need to perform alternating and reciprocating pushing actions to ensure that the probe rod 10 to be retrieved can be contacted and lifted from the correct side each time. This achieves the orderly and automatic continuous retrieval of the entire column of probe rods 10, realizing a fully automated closed loop from penetration to retrieval, and further reducing the workload of manual handling and transfer of probe rods 10.

[0028] like Figures 1 to 17As shown, preferably, the device also includes a probe storage box 8. Inside the probe storage box 8, multiple horizontal conveyor frames 801 are arranged in parallel vertically. Each horizontal conveyor frame 801 has a roughly the same structure, with the top one being slightly longer. Each frame is surrounded by an independent circulating conveyor chain 804, and multiple limiting conveyor frames 802 connected to the chain and evenly distributed around it. Each limiting conveyor frame 802 has an arc-shaped fitting conveyor groove 803 for supporting the probe material. The top opening of the conical guide cylinder 7 is connected to the top horizontal conveyor frame 801. The outer ends of the conveyor frames 801 are connected. Between the outer ends of two adjacent horizontal conveyor frames 801, an arc-shaped guide frame is fixedly installed. When it is necessary to transfer the probe 10, the probe 10 can slide smoothly from the end of the upper conveyor frame or roll into the bearing position of the lower conveyor frame along the trajectory of the arc-shaped guide frame 806 under the assistance of gravity or thrust, or be transported from the lower conveyor frame to the upper conveyor frame by the push of the chain and the limiting conveyor frame 802, realizing vertical transfer between conveyor frames of different levels. In order to realize the coordinated operation of the multi-level conveyor system, each horizontal conveyor... Each conveyor sprocket 805 driving the circulating conveyor chain 804 in the conveyor frame 801 is connected to a synchronous gear 807. The synchronous gears 807 of two adjacent horizontal conveyor frames 801 are meshed with each other. The shaft end of one of the synchronous gears 807 is connected to the output shaft of a conveyor motor 808. When the conveyor motor 808 is started, the power is transmitted through the synchronous gear 807, achieving synchronous but opposite rotation. This kinematic relationship causes the circulating conveyor chain 804 on the two adjacent horizontal conveyor frames 801 and its corresponding limiting conveyor frame 801 to rotate synchronously but in opposite directions. 2. It can move synchronously and in a coordinated manner but in opposite directions. By controlling the start, stop and turn of the conveyor motor 808, it can accurately manage the storage position and conveying process of the probe rod 10 in different levels of the storage box, realize the large-capacity orderly storage of the probe rod 10 and the continuous automatic supply to the working mechanism on demand. It can accommodate a considerable number of probe rods 10 in a limited area and arrange and manage them in an orderly manner using the built-in conveying structure, which significantly expands the number of probe rods 10 that the equipment can carry in a single operation, providing sufficient material support for deep continuous exploration.

[0029] like Figures 1 to 17As shown, preferably, a guide cleaning sleeve 9 is coaxially fixed below the insertion clamping cylinder 2. This guide cleaning sleeve 9 is fixedly connected to the main frame 1. An annular conveying pipe 901 is fixedly fixed around the bottom inner side of the guide cleaning sleeve 9. Multiple flushing nozzles 902, facing the center, are evenly arranged circumferentially on the inner wall of the annular conveying pipe 901 for spraying cleaning media, such as water or compressed air. A rotating connecting frame 903 is coaxially rotatably connected to the middle inner part of the guide cleaning sleeve 9 via a bearing structure. The inner wall of the rotating connecting frame 903 is surrounded by spiral cleaning bristles, forming a spiral cleaning brush 904. Multiple connecting arms 906 are evenly arranged circumferentially around the top inner side of the rotating connecting frame 903. The outer end of each connecting arm 906 is rotatably connected to the rotating connecting frame 903 via a pivot, and its inner end is connected to a guide roller 905 via a pivot. A buffer spring 907 is provided in the middle of the connecting arm 906, providing elasticity to ensure that the guide roller 905 always has a guiding cleaning direction. The sleeve 9 tends to press radially inward from its axial center. All guide rollers 905 and their connected rocker arms 906 are set at a uniform tilt angle relative to the axis of the guide cleaning sleeve 9. When the probe 10 slides up and down along the inner side of the guide cleaning sleeve 9 during operation, its outer surface will contact these tilted guide rollers 905 and generate rolling friction. Due to the tilt angle, this friction will generate a tangential component force, which acts on the connecting rocker arm 906 and is transmitted to the rotating connecting frame 903. This reverses the rotation of the entire rotating connecting frame 903 around its axis. The rotation of the rotating connecting frame 903 directly drives the spiral cleaning brush 904 inside to rotate synchronously. This allows the spiral cleaning brush 904 to clean the surface of the probe 10 as it passes through by rotating and brushing. As a result, the probe 10 can automatically brush and clean the dirt, gravel and other debris attached to its surface during its insertion or withdrawal strokes without manual intervention or additional downtime, ensuring the cleanliness of the probe 10 during recycling and subsequent use.

[0030] In use, the device is moved to the predetermined survey point, the reaction structure is activated, and the motor at the top of each ground anchor 103 is controlled to drive the ground anchor 103 to rotate, so that the ground anchor 103 with the spiral plate at the bottom is screwed into the ground to a predetermined depth. Multiple ground anchors 103 together provide a stable anchor for the entire main frame 1, forming a reliable reaction foundation. The first probe rod 10 is installed through the auxiliary loading and unloading mechanism. The operator puts the first probe rod 10 with a conical probe installed at the bottom end into the conical guide port 501 of the loading and unloading sleeve 5 from above, so that it passes through the penetration clamping cylinder 2. Then, the auxiliary loading and unloading mechanism is activated to clamp the upper part of the probe rod 10. The loading and unloading drive motor 507 drives the rotating drive ring 6 and the clamped probe rod 10 to rotate through gear transmission, so that its lower end is threadedly connected to the conical probe that has been placed in the position below the penetration clamping cylinder 2. After the connection is completed, the auxiliary loading and unloading mechanism releases the probe rod 10, and the penetration clamping cylinder 2 clamps the probe rod 10 under the drive of the lifting drive frame 102. The hydraulic telescopic rod 101 moves downward at a constant speed, driving the lifting drive frame 102, the insertion clamping cylinder 2, and the clamped probe rod 10 and probe to be pressed into the stratum at a constant rate. During this process, the signal cable inside the probe rod 10 transmits the soil resistance data sensed by the cone probe sensor, such as cone tip resistance and side wall friction, to the externally connected data acquisition and processing system in real time. When the first probe rod 10 penetrates to near its end, the hydraulic telescopic rod 101 stops moving. The insertion clamping cylinder 2 is used to hold the probe rod 10 already inserted into the soil in a clamped state. The next probe rod 10 is moved to the installation position and its lower end is aligned with the upper threaded interface of the probe rod 10 already inserted. The auxiliary loading and unloading mechanism is activated again to clamp the upper part of the new probe rod 10. The new probe rod 10 is driven to rotate by the rotating drive ring 6 to reliably connect it with the probe rod 10 already inserted below. After the connection is completed, the insertion clamping cylinder 2 is switched to the position of clamping the newly connected probe rod 10. The hydraulic telescopic rod 101 can then continue to drive the new probe rod 10 to be inserted at a uniform speed, thereby achieving uninterrupted continuous detection.

[0031] The soil surveying device for oil drilling engineering provided by this invention has an auxiliary loading and unloading mechanism with a loading and unloading sleeve 5 coaxial with the penetration clamping cylinder 2. Inside the sleeve, a driving component drives a rotating drive ring 6 to rotate. The rotating drive ring 6 is provided with multiple sets of horizontal guide rods 606 circumferentially. The inner end of the rod is connected to an axially sliding arc-shaped clamping plate 604, and the outer end is provided with a limiting ball 607. The top pressure clamping block 503 on the outside of the sleeve can be driven to move axially by the top pressure driving component. By squeezing the limiting ball 607 through the inner inclined surface, all the arc-shaped clamping plates 604 are pushed to move radially synchronously to clamp or release the probe rod 10. After clamping, the rotating drive ring 6 drives the probe rod 10 to rotate, realizing automatic thread docking between the probe rods 10. The arc-shaped clamping plate 604 can slide axially and is provided with a return spring to avoid rigid interference and ensure reset. This realizes the automation of the clamping, docking and disassembly of the probe rod 10, improves the continuity of operation and reduces labor intensity.
