Description

Technical Field

[0001] The invention relates to the technical field of slope sampling, and in particular to a slope sampling and collecting device for surveying and mapping. Background Art

[0002] Slope sampling is a key technology in geotechnical engineering and geological engineering, mainly used to evaluate the stability of slopes, geological structural characteristics and potential geological disaster risks. Slope sampling usually involves a systematic analysis of the physical and mechanical properties, structural characteristics and groundwater conditions of the slope rock and soil. Traditional slope sampling methods include drilling sampling, trench sampling and surface sampling, which can obtain rock and soil samples at different depths and locations, and then analyze key parameters such as strength, deformation characteristics and permeability of rock and soil through laboratory testing and field monitoring. With the development of technology, modern slope sampling has also introduced non-destructive testing technologies such as geological radar and seismic wave detection to improve the accuracy and efficiency of sampling. The data from slope sampling not only provides basic information for slope stability analysis, but also provides a scientific basis for slope reinforcement design and the establishment of disaster warning systems. Therefore, slope sampling technology has important application value in engineering practice, especially in slope engineering under complex geological conditions, where its role is particularly prominent. Slope sampling is usually carried out in different ways according to different purposes, such as sampling perpendicular to the slope and sampling perpendicular to the ground.

[0003] In the prior art, most of the slope sampling devices are handheld sampling devices. To carry the device to the slope, people also need to stand on the slope. If the height or slope is too large, it will pose a great threat to personal safety. Therefore, a device that can sample from the bottom of the slope is needed. Summary of the invention

[0004] In view of the above technical problems, the present invention discloses a slope sampling and collection device for surveying and mapping, comprising a lifting link 1 and a lifting link 2 hinged on a transfer vehicle, a mounting cross plate hinged on the lifting link 1 and the lifting link 2, a parallelogram connecting rod structure formed by the lifting link 1, the lifting link 2, the mounting cross plate and the transfer vehicle, a sampling assembly is mounted on the mounting cross plate, and the sampling assembly is controlled in position by the connecting rod structure. Through the above technical solution, the transfer vehicle drives the entire sampling structure to save manpower, and the lifting link 1, the lifting link 2 and the mounting cross plate can sample the slope soil at a higher position on the ground, and the parallelogram connecting rod structure can adjust the front and rear and height positions.

[0005] Furthermore, an angle cylinder is fixedly mounted on the lower side of the mounting cross plate, an angle connecting rod is hinged on the cylinder arm of the angle cylinder, an angle mounting plate is hinged on the end of the mounting cross plate, the angle mounting plate is connected to the angle connecting rod, a sampling assembly is vertically mounted on the angle mounting plate, and the angle of the sampling assembly is controlled by the angle cylinder. Through the above technical scheme, the sampling structure is vertically arranged with the angle mounting plate so that it can change its angle with the angle mounting plate, and the angle connecting rod drives the angle mounting plate to change its angle to adapt to different slopes. The angle mounting plate fits with the slope slope so that sampling can be performed perpendicular to the slope slope. The angle cylinder can also drive the angle mounting plate to fit with the mounting cross plate. At this time, sampling can be performed along the vertical direction on the slope, and different types of sampling can be completed.

[0006] Furthermore, a connecting groove is provided on the angle mounting plate, and a short shaft is installed at the end of the angle connecting rod, and the short shaft rolls and slides in the connecting groove. Through the above technical solution, when sampling vertically on the ground, the connecting groove is not in contact with the mounting cross plate, and after sampling starts and contacts the slope, the short shaft moves in the connecting groove to make the angle mounting plate fit with the mounting cross plate. The angle mounting plate is kept balanced only by the extension and retraction of the angle cylinder, and the angle cylinder is also pulled during the movement of the transfer vehicle, so the angle mounting plate is directly kept at a certain angle, and the force pulling the angle cylinder will become smaller, thereby extending the service life of the parts.

[0007] Furthermore, the sampling assembly includes a connecting pipe, the connecting pipe is fixedly installed on the angle mounting plate, the connecting pipe is equipped with a lifting cylinder, the cylinder arm of the lifting cylinder is equipped with a rotating motor, the output shaft of the rotating motor is equipped with a sampling shaft, the lower end of the sampling shaft is connected to the sampling tube, and the sampling tube is used to drill soil for sampling.

[0008] Furthermore, a rotating ring is rotatably mounted at the bottom of the angle mounting plate, a sliding rod is fixedly mounted on the rotating ring, two wedge blocks are slidably mounted on the sliding rod, the two wedge blocks are kept closed by a reset spring, a cleaning rod is fixedly mounted on the lower side of the wedge block, and the rotation of the wedge block drives the cleaning rod to clean the surface of the position to be sampled. Through the above technical solution, the rotation of the wedge block and the cleaning rod can clean the surface of the slope, remove weeds, stones and other debris on the slope, and ensure the cleanliness of the sampling.

[0009] Furthermore, the upper side of the wedge block is an inclined surface, on which a plurality of inclined teeth are arranged, and the bottom of the sampling tube is provided with sampling teeth, which fit the lifting cylinder angle cylinder to drive the wedge block to rotate, and the sampling teeth move downward to push the two wedge blocks apart.

[0010] Furthermore, a sampling tube box is fixedly mounted on one side of the connecting tube, a spare sampling tube is mounted in the sampling tube box, a limit hole is arranged on the upper part of the sampling tube, a rotating rod is arranged on the lower part of the sampling shaft, and the rotating rod cooperates with the limit hole to drive the sampling tube to rotate along with the sampling shaft. Through the above technical solution, the wedge block and the cleaning rod rotate and separate, making room for the sampling tube to sample downward to prevent interference, and the cooperation of the inclined teeth and the sampling teeth can drive the wedge block and the cleaning rod to rotate by rotating the ground block, and drive the wedge block to separate through the inclined surface.

[0011] Furthermore, a limit pillow is fixedly installed on the transfer vehicle, and the installation cross plate is retracted to fit the upper surface of the limit pillow. A lifting cylinder is hinged on the transfer vehicle, and the cylinder arm of the lifting cylinder drives a lifting connecting rod.

[0012] The beneficial effects of the present invention compared with the prior art are: (1) Through the technical solution of the present invention, the transfer vehicle drives the entire sampling structure to save manpower, and by lifting the first and second lifting links and installing the cross plate, it is possible to sample the sloped soil at a higher position on the ground. The parallelogram connecting rod structure can adjust the front and rear and height positions.

[0013] (2) Through the technical solution of the present invention, the sampling structure is vertically arranged with the angle mounting plate, so that the angle can change with the angle mounting plate. The angle mounting plate is driven by the angle connecting rod to change the angle to adapt to different slopes. The angle mounting plate fits with the slope slope, so that sampling can be performed perpendicular to the slope slope. The angle cylinder can also drive the angle mounting plate to fit with the mounting cross plate. At this time, sampling can be performed along the vertical direction on the slope, and different types of sampling can be completed.

[0014] (3) Through the technical solution of the present invention, when sampling vertically on the ground, the connecting groove is not in contact with the mounting cross plate. After sampling starts and the slope is contacted, the short shaft moves in the connecting groove to make the angle mounting plate fit with the mounting cross plate. The angle mounting plate is kept balanced only by the extension and retraction of the angle cylinder. The angle cylinder is also pulled during the movement of the transfer vehicle. Therefore, the angle mounting plate is kept at a certain angle directly. The force pulling the angle cylinder will be reduced, thereby extending the service life of the parts.

[0015] (4) Through the technical solution of the present invention, the rotation of the wedge block and the cleaning rod can clean the surface of the slope, remove weeds, stones and other debris on the slope, and ensure the cleanliness of the sampling.

[0016] (5) Through the technical solution of the present invention, the wedge block and the cleaning rod rotate and separate, making room for the sampling tube to take samples downward to prevent interference.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 7The slope sampling and collection device shown in the figure for surveying and mapping includes a transfer vehicle 1 and a lifting link 1 4 and a lifting link 2 5 hinged on the transfer vehicle 1. A connecting ear is provided at the rear of the transfer vehicle 1. The lifting link 1 4 and the lifting link 2 5 are hinged on the connecting ear. A cross plate 8 is hingedly installed on the lifting link 1 4 and the lifting link 2 5. The lifting link 1 4, the lifting link 2 5, the installation cross plate 8 and the transfer vehicle 1 form a parallelogram connecting rod structure. A sampling assembly is installed on the installation cross plate 8, and the position of the sampling assembly is controlled by the connecting rod structure. The transfer vehicle 1 is fixedly provided with a limit pillow 2, which is located near the front of the vehicle. After the installation cross plate 8 is retracted, it fits on the top of the limit pillow 2 to play a supporting role. The lifting link 1 4 and the lifting link 2 5 are both equipped with reinforcement rods 7 for fixing to strengthen their own strength. A connecting rod 6 is hinged at the middle position of the lifting cylinder 3 and the lifting link 2 5. The connecting rod 6 is parallel to the installation cross plate 8 and also moves in coordination as a part of the parallelogram connecting rod. The transfer vehicle 1 is hinged with a lifting cylinder 3, and the cylinder arm of the lifting cylinder 3 drives the lifting link 1 4. The lifting link 1 4 is fixedly provided with a long axis, and the cylinder arm is hinged with the long axis. The extension of the lifting cylinder 3 will drive the lifting link 1 4 and the lifting link 2 5 to move outward, and sampling will begin when they move to the appropriate position; the transfer vehicle 1 drives the entire sampling structure to save manpower, and the inclined soil at a higher position can be sampled on the ground by lifting the link 1 4, the lifting link 2 5 and the installation cross plate 8, and the parallelogram connecting rod structure can adjust the front and rear and height positions.

[0027] In this embodiment, an angle cylinder 9 is fixedly installed on the lower side of the installation cross plate 8, and an angle connecting rod 10 is hinged on the cylinder arm of the angle cylinder 9. An angle mounting plate 15 is hinged on the end of the installation cross plate 8. The angle mounting plate 15 is connected to the angle connecting rod 10, and a sampling assembly is vertically mounted on the angle mounting plate 15. The angle of the sampling assembly is controlled by the angle cylinder 9. The angle cylinder 9 is extended to drive the connection position of the angle connecting rod 10 and the angle mounting plate 15 to drop, and the angle connecting rod 10 and the angle mounting plate 15 are tilted, and the vertically mounted sampling assembly also changes its angle accordingly. A ground-attaching block 16 is provided at the end of the angle mounting plate 15, and the end of the installation cross plate 8 is attached to the slope inclined surface. The ground-attaching block 16 is adjusted to fit the slope. At this time, the angle mounting plate 15 is parallel to the slope, and then the sampling assembly can perform vertical sampling. A connecting groove 17 is provided on the angle mounting plate 15, and a short shaft is installed at the end of the angle connecting rod 10, and the short shaft rolls and slides in the connecting groove 17. The length inside the connecting groove 17 is relatively short, and only space is left for the short shaft to move. It can also play the same role of hinge. If the angle mounting plate 15 is not parallel to the mounting cross plate 8, if it is squeezed at this time, the short shaft will move in the connecting groove 17, driving the angle connecting rod 10 to rotate, and will not drive the cylinder to extend or retract. The liquid protects the cylinder to a certain extent.

[0028] In this embodiment, when sampling vertically on the ground, the connecting groove 17 is not fitted with the mounting cross plate 8. After the sampling starts and the slope is contacted, the short axis moves in the connecting groove 17 to allow the angle mounting plate 15 to fit with the mounting cross plate 8. The angle mounting plate 15 is kept balanced only by the extension and contraction of the angle cylinder 9. In addition, the angle cylinder 9 will be pulled during the movement of the transfer vehicle 1. Therefore, the angle mounting plate 15 is directly kept at a certain angle, and the force of pulling the angle cylinder 9 will be reduced, thereby extending the service life of the parts. Through the above technical solution, the sampling structure and the angle mounting plate 15 are arranged vertically, so that the angle can be changed with the angle mounting plate 15. The angle connecting rod 10 drives the angle mounting plate 15 to change its angle to adapt to different slopes. The angle mounting plate 15 fits with the slope slope, so that sampling can be performed perpendicular to the slope slope. The angle cylinder 9 can also drive the angle mounting plate 15 to fit with the mounting cross plate 8. At this time, sampling can be performed along the vertical direction on the slope, and different types of sampling can be completed.

[0029] Sampling perpendicular to the slope means that the sampling direction is perpendicular to the slope surface. This method can better reflect the structural characteristics and mechanical properties of the slope rock and soil, especially when analyzing the stability of the slope, it can obtain key data related to the potential sliding surface, which is suitable for geological surveys and stability assessments in slope engineering. Sampling perpendicular to the ground means that the sampling direction is perpendicular to the horizontal ground. This method is more commonly used in conventional geological exploration or geotechnical engineering. It can obtain the distribution characteristics and physical and mechanical parameters of the strata in the vertical direction, and is suitable for general foundation surveys or strata analysis. The choice between the two depends on the specific engineering needs: if you are concerned about the stability of the slope or the characteristics of the sliding surface, sampling perpendicular to the slope is more appropriate; if you are conducting a conventional analysis of the strata, sampling perpendicular to the ground is more commonly used.

[0030] In this embodiment, the sampling assembly includes a connecting pipe 27, which is vertically fixedly connected to the angle mounting plate 15. The connecting pipe 27 is fixedly installed on the angle mounting plate 15. The connecting pipe 27 is installed with a lifting cylinder 13.

The lower end of the sampling shaft 28 is connected to the sampling tube 26. The rotating motor 11 can drive the sampling tube 26 to rotate. The lifting cylinder 13 can drive the rotating motor 11 and the sampling tube 26 to move up and down. The sampling tube 26 can drill the soil and take samples by rotating and descending.

[0031] In this embodiment, a rotating ring 19 is rotatably mounted at the bottom of the angle mounting plate 15, a circular groove 18 is provided at the bottom of the angle mounting plate 15, the rotating ring 19 is mounted in the circular groove 18, a sliding rod 20 is fixedly mounted on the rotating ring 19, two sliding rods 20 are provided, two wedge blocks 21 are slidably mounted on the two sliding rods 20, and the wedge blocks 21 can also rotate with the rotating ring 19, the two wedge blocks 21 are kept closed by a reset spring 23, a cleaning rod 22 is fixedly mounted on the lower side of the wedge blocks 21, the cleaning rod 22 is an eccentric arc, the eccentric arc pushes the residue outward, and the rotation of the wedge blocks 21 drives the cleaning rod 22 to clean the surface of the position to be sampled. The rotation of the wedge blocks 21 and the cleaning rod 22 can clean the surface of the slope, remove weeds, stones and other debris on the slope, and ensure the cleanliness of the sampling.

[0032] In this embodiment, the upper side of the wedge block 21 is an inclined surface, and a plurality of inclined teeth 29 are arranged on the inclined surface. The bottom of the sampling tube 26 is provided with a sampling tooth 30. The sampling tooth 30 fits with the angle cylinder 9 of the lifting cylinder 3 to drive the wedge block 21 to rotate. The sampling tooth 30 moves downward to push the two wedge blocks 21 to separate. A sampling tube box 12 is fixedly installed on one side of the connecting tube 27. The sampling tube box 12 contains a spare sampling tube 26. A limiting hole 25 is arranged on the upper part of the sampling tube 26. A rotating rod 24 is arranged on the lower part of the sampling shaft 28. The rotating rod 24 cooperates with the limiting hole 25 to drive the sampling tube 26 to rotate with the sampling shaft 28. Through the above technical solution, the wedge block 21 and the cleaning rod 22 rotate and separate, making room for the sampling tube 26 to sample downward to prevent interference. Through the cooperation of the inclined teeth 29 and the sampling teeth 30, the wedge block 21 and the cleaning rod 22 can be driven to rotate by rotating the ground block 16, and the wedge block 21 can be driven to separate through the inclined surface.

[0033] Working principle: drive the transfer vehicle 1 to the side of the slope where samples need to be collected, start the lifting cylinder 3, the cylinder arm of the lifting cylinder 3 drives the lifting link 1 4 to rotate, the lifting link 1 4 will drive the lifting link 2 5, the connecting rod 6, and the installation cross plate 8, the installation cross plate 8 drives the sampling assembly close to the slope until the installation cross plate 8 fits the slope, first you can take samples perpendicular to the slope, start the angle cylinder 9, the angle cylinder 9 extends to drive the angle link 10, the angle link 10 drives the angle mounting plate 15, the angle mounting plate 15 fits the slope, at this time the angle mounting plate 15 is parallel to the slope, the sampling assembly is perpendicular to the slope, then start the sampling cylinder 14, the sampling cylinder 14 Push the sampling tube 26 in the sampling tube box 12, and push the sampling tube 26 into the connecting tube 27. At this time, the sampling cylinder 14 is not released, and the rotary motor 11 and the lifting cylinder 13 are started. The lifting cylinder 13 drives the rotating rod 24 to enter the limiting hole 25, and then the rotary motor 11 drives the sampling tube 26 to rotate, so that the rotating rod 24 is stuck in the limiting hole 25. At this time, the sampling cylinder 14 is released, and the lifting cylinder 13 drives the sampling tube 26 to continue to descend so that the sampling tooth 30 fits with the inclined tooth 29, and then the rotary motor 11 is started. The rotation of the sampling tube 26 drives the wedge block 21 and the cleaning rod 22 to rotate, and the cleaning rod 22 fits with the slope to clean up the debris on the slope surface. , exposed to the soil surface, at this time, the lifting cylinder 13 is started to drive the sampling tube 26 down, and the sampling tube 26 gradually pushes the two cleaning rods 22 through the inclined surface of the wedge block 21, and then the sampling teeth 30 cut the soil, and the sampling tube 26 enters the soil, and the soil enters the sampling tube 26. After the sampling is completed, the lifting cylinder 13 rises, driving the sampling tube 26 to leave the soil surface. At this time, the lifting cylinder 3 is started to drive the mounting cross plate 8 to rise, and then the rotating motor 11 is reversed, and then the rotating rod 24 leaves the limiting hole 25, and the sampling tube 26 falls naturally. The gravity of the sampling tube 26 and the soil is greater than the clamping force between the two wedge blocks 21, and it falls naturally. The sampling is completed. If vertical ground sampling is required, then First, make the angle mounting plate 15 parallel to the slope and then clean up the debris on the slope. Then recycle the angle cylinder 9 and make the angle mounting plate 15 approximately parallel to the mounting cross plate 8. Then start the rotating motor 11 and the lifting cylinder 13 to drive the sampling tube 26 for sampling. After the sampling tube 26 contacts the slope, it pushes the angle mounting plate 15 back to fit the mounting cross plate 8. At this time, it is perpendicular to the ground for sampling. After sampling, it is released. The sampling tube 26 rolls to the bottom of the slope and is collected manually. Then, the sampling cylinder 14 pushes another sampling tube 26 into the connecting pipe 27 for sampling again. After use, retract the lifting cylinder 3, and finally make the mounting cross plate 8 contact the support of the limit pillow 2 for retraction.
