Description
Technical Field
[0001] The invention relates to the technical field of geological exploration, and in particular to an engineering geological exploration sampling device. Background Art
[0002] An engineering geological survey sampling device is a special device used to collect soil or rock samples during geological survey. This device is usually designed to solve sampling problems in specific geological surveys, such as the collection of undisturbed soil samples in deep rock and soil. It may contain a variety of mechanisms and components to achieve precise control, stable support and efficient collection during the sampling process.
[0003] If the engineering geological survey sampling device cannot take samples simultaneously with drilling, it will increase the operation steps and time cost. After drilling, special equipment and processes need to be arranged for sampling. The number of operation steps increases and more people are required to participate, which increases the cost of the survey project. Summary of the invention
[0004] The invention discloses an engineering geological survey sampling device, aiming to solve the technical problem that if the engineering geological survey sampling device cannot drill the ground and sample synchronously, the operation steps, time and labor cost will be increased.
[0005] In order to achieve the above object, the present invention adopts the following technical solutions: An engineering geological survey sampling device comprises a working frame, the top of the working frame is fixedly connected to a connecting frame, the bottom of the working frame is fixedly connected to a plurality of columns, and the bottoms of the columns are all fixedly connected to a stabilizing component, an automatic ground-drilling sampling cylinder is arranged inside the connecting frame, a plurality of rectangular holes are opened at the bottom of the automatic ground-drilling sampling cylinder, and a sampling component is fixedly connected to the inner top of the connecting frame; The sampling assembly comprises a sampling frame, both sides of the top of the sampling frame are fixedly connected with symmetrical plates, and the sampling frame is located directly above the automatic ground drilling sampling cylinder, and the top of the symmetrical plate is fixedly connected with a sliding rope; The stabilizing assembly includes a plurality of ground-boring members, the top ends of the ground-boring members are fixedly connected to electric telescopic rods, the top ends of the electric telescopic rods are fixedly connected to connecting seats, and the outer sides of the connecting seats are fixedly connected to support plates, and the bottom ends of the support plates are in contact with the ground.
[0006] In a preferred embodiment, the sampling assembly further comprises an arc frame, the top end of the arc frame is fixedly connected to the inner side of the connecting frame, and the inner side of the arc frame is fixedly connected to a fixing piece, one side of the arc frame is fixedly connected to a connecting gear rod, the outer side of the connecting gear rod is movably connected to a rotating gear, the rotating gear and the connecting gear rod are meshed through a tooth groove, the outer side of the rotating gear is connected to a rotating motor through a coupling, the bottom end of the rotating motor is fixedly connected to a motor frame, and the front end of the motor frame is fixedly connected to one side of the arc frame, and the arc frame is away from the side of the connecting gear rod. A retaining rod is fixedly connected, and the bottom end of the fixing piece is fixedly connected to the connecting gear rod and one side of the retaining rod. The end of the rotating gear away from the rotating motor is fixedly connected to a rotating rod, and a rope collecting piece is fixedly connected to the outer side of the rotating rod. Both ends of the rope collecting piece are fixedly connected to the top of the sliding rope, and the rope collecting piece is located in front of the fixing piece. An auxiliary plate is fixedly connected to the bottom end of the connecting gear rod and the fixing rod, and a rectangular hole is opened on the auxiliary plate. The auxiliary plate is located between the sampling frame and the automatic drilling sampling barrel, and both ends of the auxiliary plate are fixedly connected to the two sides inside the connecting frame.
[0007] By providing a sampling assembly, when sampling is performed, the rotating motor is powered on and started, and the rotating gear rotates accordingly. The rotation of the rotating gear drives the connecting gear rod to rotate around its own axis. When the rotating gear rotates, the rotating rod rotates synchronously, and the rope collecting piece on the outside of the rotating rod rotates with the rotating rod and begins to wrap around the sliding rope. As the rope collecting piece collects the sliding rope, the length of the sliding rope is shortened, thereby pulling the symmetrical plates on both sides of the sampling frame, so that the sampling frame moves downward in the vertical direction. During the descent process, the sampling frame gradually approaches and passes through the rectangular hole of the auxiliary plate. The two ends of the auxiliary plate are fixedly connected to the two sides inside the connecting frame, which plays a certain guiding and limiting role in the descent of the sampling frame, ensuring that the sampling frame vertically descends into the automatic drilling sampling barrel. The sampling frame continues to descend and finally enters the automatic drilling sampling barrel. After the automatic drilling sampling barrel completes drilling and partially remains on the ground, the barrel is filled with soil samples. The sampling frame can collect samples after entering. After the sampling is completed, the rotating motor is reversed, and the rotating rod drives the rope collecting piece to rotate in the opposite direction to release the sliding rope. Under the action of gravity or possible resetting auxiliary devices, the sampling frame rises along the original path, leaves the automatic drilling sampling tube, passes through the rectangular hole of the auxiliary plate, and returns to the initial position. During the process, engineering geological surveys can directly conduct soil sampling and testing during the drilling process, without the need to arrange additional drilling or excavation work specifically for sampling, saving time and labor costs, speeding up the entire survey progress, and can immediately send the taken soil samples to the laboratory for testing, quickly obtaining data such as the physical and mechanical properties of the soil, and providing timely basis for subsequent engineering design and construction.
[0008] In a preferred scheme, the top of the automatic drilling sampling tube is fixedly connected to a sliding frame, circular holes are opened at both ends of the sliding frame, and the circular hole away from the rotating motor is movably connected to a guide column, and the circular hole close to the rotating motor is movably connected to a rotating screw rod, the tops of the rotating screw rod and the guide column are fixedly connected to a sliding limit seat, and one side of the sliding limit seat is fixedly connected to the inner side of the connecting frame, the bottom end of the rotating screw rod is connected to a driving motor through a coupling, the bottom ends of the driving motor and the guide column are fixedly connected to a base, and the outer side of the base is fixedly connected to the inner side of the connecting frame.
[0009] In a preferred solution, the stabilizing component also includes a protective shell, the top of the protective shell is fixedly connected to the bottom end of the column, and the inner top of the protective shell is fixedly connected to a servo motor, the power output shaft of the servo motor is connected to a threaded rod through a coupling, the outer side of the threaded rod is movably connected to a sliding seat, the outer side of the sliding seat is fixedly connected to a plurality of driving rods, and the bottom end of the driving rod is fixedly connected to the inner side of the support plate, the inner side of the support plate is fixedly connected to the driving rod, the driving rod and the movable rod are cross-shaped, the bottom end of the driving rod is fixedly connected to a fixed seat, the top of the fixed seat is fixedly connected to the bottom end of the threaded rod, and the bottom end of the fixed seat is in contact with the ground, and the center position of the driving rod and the movable rod is movably connected with a mounting part.
[0010] By providing a stabilizing component, when sampling is performed, the electric telescopic rod is started, the electric telescopic rod begins to extend, and the ground-drilling piece connected thereto is pushed downward, and the ground-drilling piece gradually approaches the ground and begins to be inserted into the ground. The extension of the electric telescopic rod drives the connecting seat to rise, and the connecting seat keeps the support plate in a horizontal state and in full contact with the ground, providing preliminary support and stability for the entire stabilizing component. The servo motor is started to drive the threaded rod to rotate, and the rotation of the threaded rod causes the sliding seat to move along the axial direction of the threaded rod. When the sliding seat moves downward, it drives the driving rod connected thereto to move downward. Because the driving rod and the movable rod are in a cross shape and there is a mounting piece movably connected at the center position, the movement of the driving rod causes the movable rod to swing and displace accordingly. The two cooperate with each other to further adjust the position and angle of the support plate, so that it can better adapt to the ground conditions and enhance the supporting effect. The fixed seat at the bottom end of the driving rod moves downward with the movement of the driving rod until it is in close contact with the ground, and works together with the support plate to share and transmit the reaction force generated by the insertion of the ground-drilling piece into the ground, so that the entire stabilizing component is more firmly supported on the ground, ensuring the stability of the equipment during the sampling process.
[0011] From the above, it can be seen that the engineering geological survey sampling device provided by the present invention has the technical effect of directly sampling and testing when drilling in engineering geological survey, without the need for additional drilling and excavation, saving manpower time, accelerating the progress of the survey, and taking out soil samples for inspection immediately, quickly obtaining soil data, and providing timely basis for subsequent projects.

A fixing rod 1213 is fixedly connected, and the bottom end of the fixing member 1202 is fixedly connected to the connecting gear rod 1203 and one side of the fixing rod 1213. The end of the rotating gear 1208 away from the rotating motor 1210 is fixedly connected to the rotating rod 1212, and the outer side of the rotating rod 1212 is fixedly connected to a rope collecting member 1211, and both ends of the rope collecting member 1211 are fixedly connected to the top of the sliding rope 1204, and the rope collecting member 1211 is located in front of the fixing member 1202, and the connecting gear rod 1203 and the bottom end of the fixing rod are fixedly connected to an auxiliary plate 1207, and a rectangular hole is opened on the auxiliary plate 1207, and the auxiliary plate 1207 is located between the sampling frame 1206 and the automatic drilling sampling tube 5, and the two ends of the auxiliary plate 1207 are fixedly connected to the two sides inside the connecting frame 2.
[0024] In a specific embodiment, when sampling is performed, the rotating motor 1210 is powered on and started, and the rotating gear 1208 rotates accordingly. The rotation of the rotating gear 1208 drives the connecting gear rod 1203 to rotate around its own axis. When the rotating gear 1208 rotates, the rotating rod 1212 rotates synchronously, and the rope receiving member 1211 on the outside of the rotating rod 1212 rotates with the rotating rod 1212 and begins to wrap around the sliding rope 1204. As the rope receiving member 1211 collects the sliding rope 1204, the length of the sliding rope 1204 is shortened, thereby pulling the symmetrical plates 1205 on both sides of the sampling frame 1206, so that the sampling frame 1206 moves downward along the vertical direction, and the sampling frame 120 During the descent, the frame 1206 gradually approaches and passes through the rectangular hole of the auxiliary plate 1207. The two ends of the auxiliary plate 1207 are fixedly connected to the two sides of the inside of the connecting frame 2, which plays a certain guiding and limiting role in the descent of the sampling frame 1206, ensuring that the sampling frame 1206 vertically descends into the automatic ground-drilling sampling tube 5. The sampling frame 1206 continues to descend and finally enters the automatic ground-drilling sampling tube 5. After the automatic ground-drilling sampling tube 5 completes drilling and partially stays on the ground, the tube is filled with soil samples. After the sampling frame 1206 enters, the sample can be collected. After the sampling is completed, the rotating motor 1210 reverses, and the rotating rod 1212 drives the rope receiving member 1211 to rotate in the opposite direction, releasing the sliding rope 1204. Under the action of gravity or the possible reset auxiliary device, the sampling frame 1206 rises along the original path, leaves the automatic ground-drilling sampling tube 5, passes through the rectangular hole of the auxiliary plate 1207, and returns to the initial position.
[0025] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the top of the automatic drilling sampling tube 5 is fixedly connected to a sliding frame 6, and circular holes are opened at both ends of the sliding frame 6, and the inner part of the circular hole away from the rotating motor 1210 is movably connected to a guide column 7, and the inner part of the circular hole close to the rotating motor 1210 is movably connected to a rotating screw 9, and the tops of the rotating screw 9 and the guide column 7 are fixedly connected to a sliding limit seat 10, and one side of the sliding limit seat 10 is fixedly connected to the inner side of the connecting frame 2, and the bottom end of the rotating screw 9 is connected to a driving motor 11 through a coupling, and the bottom ends of the driving motor 11 and the guide column 7 are both fixedly connected to a base 8, and the outer side of the base 8 is fixedly connected to the inner side of the connecting frame 2.
[0026] Reference Figure 1 , Figure 6 and Figure 7In a preferred embodiment, the stabilizing component 4 also includes a protective shell 401, the top of the protective shell 401 is fixedly connected to the bottom end of the column 3, and the inner top of the protective shell 401 is fixedly connected to a servo motor 406, the power output shaft of the servo motor 406 is connected to a threaded rod 403 through a coupling, the outer side of the threaded rod 403 is movably connected to a sliding seat 402, the outer side of the sliding seat 402 is fixedly connected to a plurality of driving rods 412, and the bottom ends of the driving rods 412 are fixedly connected to the inner side of the support plate 405, the inner side of the support plate 405 is fixedly connected to the driving rods 412, the driving rods and the movable rods 407 are cross-shaped, the bottom ends of the driving rods 412 are fixedly connected to the fixed seat 404, the top of the fixed seat 404 is fixedly connected to the bottom end of the threaded rod 403, and the bottom end of the fixed seat 404 is in contact with the ground, and the center positions of the driving rods 412 and the movable rods 407 are movably connected to the mounting member 408.
[0027] In a specific embodiment, when sampling is performed, the electric telescopic rod 410 is started, the electric telescopic rod 410 begins to extend, and pushes the ground-drilling piece 411 connected thereto to move downward, the ground-drilling piece 411 gradually approaches the ground and begins to be inserted into the ground, the electric telescopic rod 410 extends to drive the connecting seat 409 to rise, and the connecting seat 409 keeps the support plate 405 in a horizontal state and in full contact with the ground, providing preliminary support and stability for the entire stabilizing component 4, and the servo motor 406 is started to drive the threaded rod 403 to rotate, and the rotation of the threaded rod 403 causes the sliding seat 402 to move along the axial direction of the threaded rod 403, and when the sliding seat 402 moves downward, it drives the driving seat connected thereto. The rod 412 moves downward, and because the driving rod 412 and the movable rod 407 are in a cross shape and are movably connected by a mounting part 408 at the center position, the movement of the driving rod 412 will cause the movable rod 407 to swing and displace accordingly, and the two cooperate with each other to further adjust the position and angle of the support plate 405 to make it better adapt to the ground conditions and enhance the supporting effect. The fixed seat 404 at the bottom end of the driving rod 412 moves downward with the movement of the driving rod 412 until it is in close contact with the ground, and works together with the support plate 405 to share and transmit the reaction force generated by the insertion of the drilling piece 411 into the ground, so that the entire stabilizing component 4 is more firmly supported on the ground, ensuring the stability of the equipment during the sampling process.
[0028] Working principle: before sampling, the electric telescopic rod 410 in the stabilizing component 4 is started, pushing the ground drilling piece 411 to move downward, and the ground drilling head is gradually inserted into the ground. As the electric telescopic rod 410 is extended, the ground drilling piece 411 penetrates into the ground, and the support plate 405 contacts the ground and gradually stabilizes, providing a stable support for the entire working frame 1. The automatic ground drilling sampling tube 5 is connected to the guide column 7 and the rotating screw 9 in the connecting frame 2 through the sliding frame 6 at the top, and the driving motor 11 is in a standby state. The sliding limit seat 10 at the top of the guide column 7 and the rotating screw 9 is fixed to the inner side of the connecting frame 2 to ensure that the automatic ground drilling sampling tube 5 moves stably in the vertical direction; When drilling, the driving motor 11 is started, driving the rotating screw 9 to rotate. Since the circular holes on the sliding frame 6 cooperate with the guide column 7 and the rotating screw 9 respectively, under the action of the rotation of the rotating screw 9, the automatic drilling sampling tube 5 moves downward along the guide column 7 and gradually enters the ground. In this process, the soil on the ground enters the interior of the tube through the multiple rectangular holes opened at the bottom of the automatic drilling sampling tube 5. When the automatic drilling sampling tube 5 reaches a predetermined depth, the driving motor 11 reverses and drives the automatic drilling sampling tube 5 to move upward. When it moves to a certain position, only the part below the rectangular hole in the automatic drilling sampling tube 5 is retained in the ground. At this time, the soil in the ground has filled the space in the tube from the rectangular hole to the current position. When sampling, the sliding rope 1204 of the sampling assembly 12 starts working, pulling the sampling frame 1206 down. Since the symmetrical plates 1205 on both sides of the top of the sampling frame 1206 are connected to the sliding rope 1204, the sampling frame 1206 is pulled vertically downward into the automatic drilling sampling tube 5 by the sliding rope 1204. The sampling frame 1206 descends to a suitable position and collects the soil sample above the rectangular hole in the automatic drilling sampling tube 5 to complete the sampling action. Subsequently, the sliding rope 1204 pulls up the sampling frame 1206 and leaves the automatic drilling sampling tube 5 with the collected sample. At this point, the entire sampling process ends.
