Description

Technical Field

[0001] The utility model relates to the technical field of sampling for geotechnical engineering construction, in particular to a sampling device for geotechnical engineering construction. Background Art

[0002] Geotechnical engineering construction sampling usually refers to the investigation and sampling of ground rock and soil before construction, in order to understand the geological conditions, stratum conditions, etc., and provide necessary data and basis for engineering design and construction. These samples can be used to test the mechanical properties of soil, such as density, water content, particle distribution, etc., and can also analyze the strength and compression properties of rocks. This information is very important for the foundation design, construction method selection and engineering quality control of the project. When conducting rock and soil investigation and sampling operations, special sampling devices are required to collect and sample the sand and gravel protruding from the ground.

[0003] At present, during the use of existing sampling devices for geotechnical engineering construction, a drill rod is usually used to drill deep into the ground. During the continuous rotation, the rock and soil are rotated out to the surface, and then they need to be manually grabbed and packaged. The operation is cumbersome, and contactless sampling cannot be achieved. The data has certain deviations and defects. Utility Model Content

[0004] (1) Technical problems solved

[0005] In response to the shortcomings of the existing technology, the utility model provides a sampling device for geotechnical engineering construction, which has the advantages of being able to collect rock and soil quickly and contactlessly, and solves the problems of manual sampling at the current stage, such as cumbersome operation and data deviation.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling device for geotechnical engineering construction, comprising a base assembly, a sampling assembly, an auxiliary assembly and a sampling assembly, the base assembly comprising a device base, a mounting groove being provided on the device base, a docking hole being provided in the mounting groove, an auxiliary groove being provided at the bottom of the device base, the docking hole passing through the auxiliary groove, and an electric telescopic rod being fixed on the device base, the device base being used to improve the overall stability of the device, and the auxiliary groove being inclined toward the outer edge, so that during the rotating sampling process of the drill rod, larger stones can be retained in the auxiliary groove, thereby avoiding the problem of stones being stuck between the drill rod and the docking hole, causing damage to the drill rod.

[0008] The sampling assembly includes a support rod fixed to the side of the device base, a supporting plate fixed on the support rod, a driving motor fixed on the supporting plate, an output end of the driving motor passes through the supporting plate and is fixed with a connecting pipe, a drill rod is installed at one end of the connecting pipe, support rods are fixed at corresponding positions on both sides of the device base, and supporting plates are installed on the two support rods. By installing the support rods and the supporting plates, the driving motor can be elevated. When the driving motor is operating, its output end can drive the connecting pipe to rotate, so that the drill rod installed at the bottom can be inserted into the ground to survey and sample rocks.

[0009] The auxiliary component includes an auxiliary pressure plate fixed on the output end of the electric telescopic rod, and a docking plate is fixed at the bottom of the auxiliary pressure plate. The docking plate corresponds to the position of the mounting slot. When the output end of the electric telescopic rod is extended and retracted, the auxiliary pressure plate is lifted up and down. When the auxiliary pressure plate rises to the limit, the mounting slot is opened, so that the sampling component can be placed in the mounting slot or taken out of the mounting slot. When the auxiliary pressure plate falls to the limit, the mounting slot is sealed and the sampling component is pressed in the mounting slot to prevent the sampling component from escaping from the mounting slot.

[0010] The sampling assembly is movably sleeved in the mounting groove, and the sampling assembly includes a sampling barrel, a sampling cover plate is threadedly connected to the sampling barrel, a stabilizing hole is opened on the sampling cover plate, and the stabilizing hole passes through the bottom of the sampling barrel. At the same time, the drill rod is movably sleeved in the stabilizing hole, and the interface at the top of the sampling barrel and the sampling cover plate are installed by threaded connection. A stabilizing hole that passes through the bottom of the sampling barrel is opened in the center position of the sampling cover plate, and the diameter of the stabilizing hole coincides with the diameter of the side of the drill rod, thereby ensuring the stability of the rotation of the drill rod and preventing the drill rod from inputting the sampled sand and gravel into the sampling barrel and flowing out from the bottom of the stabilizing hole.

[0011] As a further improvement of the above solution, a spring push rod is fixed in the installation groove, and the spring push rod is attached to the bottom of the sampling tube.

[0012] Through the above technical solution, the spring push rod is used to push the sampling tube upward from the installation groove, making it easier to take the sampling component.

[0013] As a further improvement of the above solution, a positioning screw is fixed to the bottom of the device base.

[0014] Through the above technical solution, when the bottom of the device base is in contact with the ground, the positioning screw is rotated so that the screw is inserted into the ground, thereby fixing the position of the entire device and improving the stability of the device during operation.

[0015] As a further improvement of the above solution, one end of the connecting pipe is movably hinged with an adjusting ring, which is threadedly connected to the side of the drill rod. At the same time, the side of the adjusting ring is threadedly connected to a locking rod, and one end of the locking rod is attached to the side of the drill rod.

[0016] Through the above technical solution, a screw is provided at the top of half of the overall length of the drill rod, and is connected to the inner thread of the regulating ring. The drill rod and the inside of the connecting pipe can only be telescopically moved up and down, and cannot be rotated. The length of the drill rod can be adjusted by rotating the regulating ring clockwise or counterclockwise.

[0017] As a further improvement of the above solution, multiple transmission motors are fixed to the bottom of the docking plate, and a transmission button is fixed to the output end of the transmission motor. At the same time, the sampling cover is movably hinged with multiple threaded rods, and the transmission button is inserted into one end of the threaded rod.

[0018] Through the above technical solution, transmission motors are installed on the docking plate at corresponding positions at both ends away from the center position. At the same time, the position of the threaded rod installed on the sampling cover corresponds to the position of the transmission button. At the same time, a hole that matches the shape of the transmission button is opened on the threaded rod. When the auxiliary pressure plate descends, the transmission button can be inserted into the hole of the threaded rod and rotated by the transmission motor to realize that the bottom end of the threaded rod is threadedly connected to the bottom of the sampling barrel, thereby achieving the function of fixing the cover and the barrel.

[0019] As a further improvement of the above solution, the docking plate is fixed with multiple micro-telescopic rods, the output end of the micro-telescopic rod is fixed with a linkage plate, one end of the linkage plate is fixed with a suction cup, and a convex button is fixed on the sampling cover plate. One end of the suction cup passes through the docking plate and is adsorbed on the convex button.

[0020] Through the above technical solution, multiple micro telescopic rods are installed in a cross shape at equal intervals on the four directions of the docking plate and operate synchronously. When the output end of the micro telescopic rod telescopes, the suction cup device is driven to telescope through the linkage plate. After the auxiliary pressure plate rises, the sampling component is plugged into the interface of the suction cup device through the convex button on the cover plate. After the suction cup device operates, the sampling cover plate is adsorbed and fixed, so that after the auxiliary pressure plate descends, the sampling component can be accurately input into the installation slot. Until the auxiliary pressure plate is tightly attached to the top of the device base, the suction cup device stops the adsorption work, so that the sampling component stays in the installation slot.

[0021] As a further improvement of the above solution, an air pipe is fixed to one end of the suction cup device, and one end of the air pipe passes through the auxiliary pressure plate.

[0022] Through the above technical solution, when the sucker is in operation, the air is exhausted through the air pipe, thereby adsorbing and fixing the convex button, and when the air pipe supplies air, the sucker is separated from the convex button.

[0023] Compared with the prior art, the present invention provides a sampling device for geotechnical engineering construction, which has the following beneficial effects:

[0024] 1. The sampling device for geotechnical engineering construction uses the suction force of the suction cup to adsorb the sampling component to the bottom of the docking plate, and the auxiliary pressure plate is lowered to install and fix the sampling component in the installation groove. The drill rod is inserted into the stabilizing hole and the docking hole, and drills into the rock and soil during the rotation process. In the state of continuous rotation, the rock and soil are input into the sampling component from the stabilizing hole. The auxiliary pressure plate rises, and under the action of the spring push rod, the sampling component pops up, thereby achieving the effect of convenient sampling.

[0025] 2. The sampling device for geotechnical engineering construction can adjust the length of the drill rod by rotating the control ring to allow the drill rod to extend and retract in the connecting pipe, thereby meeting the requirements of sampling in survey areas of rock and soil at different depths.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1

[0043] See also Figure 1-10 As shown, the sampling device for geotechnical engineering construction proposed in this embodiment includes a base assembly 1, a sampling assembly 2, an auxiliary assembly 3 and a sampling assembly 4. The base assembly 1 includes a device base 101, a mounting groove 102 is provided on the device base 101, a docking hole 103 is provided in the mounting groove 102, and an auxiliary groove 105 is provided at the bottom of the device base 101, and the docking hole 103 passes through the auxiliary groove 105. At the same time, an electric telescopic rod 107 is fixed on the device base 101. The device base 101 is used to improve the overall stability of the device, and the auxiliary groove 105 is inclined toward the outer edge, so that the drill rod 208 can retain larger stones in the auxiliary groove 105 during the rotating sampling process, thereby avoiding the problem of stones being stuck between the drill rod 208 and the docking hole 103, causing damage to the drill rod 208.

[0044] The sampling assembly 2 includes a support rod 201 fixed to the side of the device base 101, a supporting plate 202 is fixed on the support rod 201, a driving motor 204 is fixed on the supporting plate 202, the output end of the driving motor 204 passes through the supporting plate 202 and is fixed with a connecting pipe 205, and a drill rod 208 is installed at one end of the connecting pipe 205. Support rods 201 are fixed at corresponding positions on both sides of the device base 101, and supporting plates 202 are installed on the two support rods 201. When the support rods 201 and the supporting plate 202 are installed, the driving motor 204 is elevated. When the driving motor 204 is operating, its output end can drive the connecting pipe 205 to rotate, so that the drill rod 208 installed at the bottom is inserted into the ground to survey and sample the rock.

[0045] The auxiliary component 3 includes an auxiliary pressure plate 301 fixed on the output end of the electric telescopic rod 107, and a docking plate 302 is fixed at the bottom of the auxiliary pressure plate 301. The docking plate 302 corresponds to the position of the mounting slot 102. The output end of the electric telescopic rod 107 is in a state of up and down extension, causing the auxiliary pressure plate 301 to rise and fall. When the auxiliary pressure plate 301 rises to the limit, the mounting slot 102 is opened, so that the sampling component 4 can be placed in the mounting slot 102 or taken out of the mounting slot 102. When the auxiliary pressure plate 301 falls to the limit, the mounting slot 102 is sealed and the sampling component 4 is pressed in the mounting slot 102 to prevent the sampling component 4 from escaping from the mounting slot 102.

[0046] The sampling assembly 4 is movably sleeved in the mounting groove 102. The sampling assembly 4 includes a sampling barrel 401, a sampling cover 402 is threadedly connected to the sampling barrel 401, a stabilizing hole 403 is opened on the sampling cover 402, and the stabilizing hole 403 passes through the bottom of the sampling barrel 401. At the same time, the drill rod 208 is movably sleeved in the stabilizing hole 403, and the interface at the top of the sampling barrel 401 and the sampling cover 402 are installed by threaded connection. A stabilizing hole 403 that passes through the bottom of the sampling barrel 401 is opened in the center position of the sampling cover 402. The diameter of the stabilizing hole 403 is consistent with the diameter of the side of the drill rod 208, thereby ensuring the stability of the rotation of the drill rod 208 and preventing the drill rod 208 from inputting the sampled sand and gravel into the sampling barrel 401 and flowing out from the bottom of the stabilizing hole 403.

[0047] The working principle of the sampling device for geotechnical engineering construction proposed in this embodiment is as follows: when in use, the device is placed at the desired sampling position, and the positioning screw 106 is drilled into the ground to fix the position of the device. After fixing, the sampling component 4 is adsorbed on the interface of the suction cup 305 at the bottom of the auxiliary pressure plate 301 through the convex button 405 on the cover plate, and then the output end of the electric telescopic rod 107 is controlled to retract, so that the auxiliary pressure plate 301 moves downward and fits on the device base 101, and the sampling component 4 is accurately inserted into the installation groove 102. At this time, the length of the drill rod 208 is adjusted by rotating the regulating ring 206 clockwise or counterclockwise. Adjustment is performed. After the adjustment is completed, ensure that the drill rod 208 passes through the stabilizing hole 403 and the docking hole 103 and is inserted into the ground. At this time, the locking rod 207 is rotated so that the front end of the locking rod 207 is tightly attached to the side of the drill rod 208 for fixation. At this time, the drive motor 204 is controlled to operate to rotate the drill rod 208 to transport the underground sand and gravel into the sampling tube 401. After the real-time sampling is completed, the drill rod 208 is controlled to stop operating, and the output end of the electric telescopic rod 107 is controlled to extend, so that the auxiliary pressure plate 301 is raised, and the sampling assembly 4 is lifted up by the spring push rod 104. The operator can take out the sampling assembly 4 after sampling is completed.

[0048] Furthermore, a spring push rod 104 is fixed in the mounting groove 102 , and the spring push rod 104 is attached to the bottom of the sampling tube 401 .

[0049] More specifically, the spring push rod 104 is used to push the sampling tube 401 upward out of the installation slot 102 , making it easier to take the sampling assembly 4 .

[0050] Furthermore, a positioning screw 106 is fixed to the bottom of the device base 101 .

[0051] More specifically, when the bottom of the device base 101 is in contact with the ground, the positioning screw 106 is rotated so that the screw is inserted into the ground, thereby fixing the position of the entire device and improving the stability of the device during operation.

[0052] Furthermore, one end of the connecting tube 205 is movably hinged with an adjusting ring 206, which is threadedly connected to the side of the drill rod 208. At the same time, the side of the adjusting ring 206 is threadedly connected to a locking rod 207, and one end of the locking rod 207 is attached to the side of the drill rod 208.

[0053] More specifically, a screw is provided at the top of half the overall length of the drill rod 208, and is connected to the internal thread of the regulating ring 206. The drill rod 208 can only be telescopically moved up and down between the inside of the connecting tube 205, and cannot be rotated. The length of the drill rod 208 can be adjusted by rotating the regulating ring 206 clockwise or counterclockwise.

[0054] Furthermore, a plurality of transmission motors 303 are fixed to the bottom of the docking plate 302 , and a transmission button 304 is fixed to the output end of the transmission motor 303 . At the same time, the sampling cover plate 402 is movably hinged with a plurality of threaded rods 404 , and the transmission button 304 is inserted into one end of the threaded rod 404 .

[0055] More specifically, a transmission motor 303 is installed on the docking plate 302 at corresponding positions at both ends away from the center position. At the same time, the position of the threaded rod 404 installed on the sampling cover 402 corresponds to the position of the transmission button 304. At the same time, a hole that matches the shape of the transmission button 304 is opened on the threaded rod 404. When the auxiliary pressure plate 301 descends, the transmission button 304 can be inserted into the hole of the threaded rod 404 and rotated by the transmission motor 303, so that the bottom end of the threaded rod 404 is threadedly connected to the bottom of the sampling cylinder 401, thereby fixing the cover and the cylinder.

[0056] Furthermore, the docking plate 302 is fixed with multiple micro telescopic rods 307, the output end of the micro telescopic rod 307 is fixed with a linkage plate 308, one end of the linkage plate 308 is fixed with a suction cup 305, and at the same time, a convex button 405 is fixed on the sampling cover 402, one end of the suction cup 305 passes through the docking plate 302 and is adsorbed on the convex button 405.

[0057] More specifically, multiple micro telescopic rods 307 are equidistantly installed in a cross shape at four directional positions on the docking plate 302 and operate synchronously. When the output end of the micro telescopic rod 307 telescopes, the sucker 305 is driven to telescope through the linkage plate 308. After the auxiliary pressure plate 301 rises, the sampling component 4 is plugged into the interface of the sucker 305 through the convex button 405 on the cover. After the sucker 305 operates, the sampling cover 402 is adsorbed and fixed, so that after the auxiliary pressure plate 301 descends, the sampling component 4 can be accurately input into the installation groove 102. Until the auxiliary pressure plate 301 is tightly attached to the top of the device base 101, the sucker 305 stops the adsorption work, so that the sampling component 4 stays in the installation groove 102.

[0058] Furthermore, an air pipe 306 is fixed to one end of the suction cup 305 , and one end of the air pipe 306 passes through the auxiliary pressure plate 301 .

[0059] More specifically, when the suction cup 305 is in operation, the air is discharged through the air pipe 306 , thereby adsorbing and fixing the convex button 405 . When the air pipe 306 supplies air, the suction cup 305 is separated from the convex button 405 .

[0060] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
