Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of geological detection equipment, and particularly relates to a geological survey rock-soil hardness detection equipment. BACKGROUND

[0002] By detecting the rock-soil hardness, potential risks such as foundation stability and slope instability can be identified, and engineering cracking, settlement or collapse accidents caused by unknown geological conditions can be avoided, which is the first line of defense for engineering safety.

[0003] In the detection, the collected rock-soil sample is placed into the detection equipment, the rock-soil sample is pressed downward, the stress condition of the rock-soil sample under different pressures is observed, and the soil condition of the collection site of the rock-soil sample can be analyzed. This detection process generally needs to collect multiple rock-soil samples from the same collection site to ensure that the collected data is real and accurate. When there is hard material in the rock-soil, the rock-soil will suddenly break when the stress reaches the limit during the hardness detection, and the data collected by the sensor at the moment of breaking will have obvious fluctuation difference with the previous data.

[0004] The conventional geological survey rock-soil hardness detection equipment lacks a stable and accurate detection structure during the detection of the rock-soil sample, resulting in uneven detection pressure, and the relevant sensor has a large fluctuation in the collected data before and after the sudden breaking of the hard material in the rock, which causes the hardness detection results of the rock-soil sample before and after breaking to have poor accuracy.

When the rock sample is broken, the slag falls on the surface of the support plate 49. The surface of the support plate 49 needs to be cleaned before the next rock sample detection. The traditional manual cleaning is low in efficiency and is affected by various factors such as personnel emotions and physical conditions, which may result in incomplete cleaning and affect the accuracy of the next detection data. After the rock sample is broken, the second motor 42 is started to drive the first connecting rod 43 and the tray 44 at the top of the first connecting rod 43 to rotate.

[0047] Embodiment two

A second spring 36 is filled between the sealing cover 22 and the screw 23, by filling the hydraulic medium between the sealing cover 22 and the lower pressing plate 21, and connecting the sealing cover 22 and the sealing cylinder 31 through the large flow guide pipe 32 and the small flow guide pipe 33, so that the hydraulic medium can flow between the sealing cover 22 and the sealing cylinder 31, when the lower pressing plate 21 abuts against the rock sample, and the sealing cover 22 is close to the lower pressing plate 21 during the process of descending, the hydraulic medium in the sealing cover 22 will be extruded by the pressure and enter the sealing cylinder 31 from bottom to top through the one-way valve 34 on the large flow guide pipe 32, the hydraulic medium entering the sealing cylinder 31 will again push the piston block 35 connected to the piston in the sealing cylinder 31 to move and compress the second spring 36, thereby increasing the resistance to the entry of the hydraulic medium, reducing the descending speed of the sealing cover 22, making the downward pressure more stable and uniform, thereby improving the accuracy of the signal collected by the first pressure sensor 211, and when the rock sample suddenly breaks, the originally compressed first spring 212 will suddenly rebound and reset, pushing the first pressure sensor 211 and the lower pressing plate 21 to move downward, at this time the negative pressure generated in the sealing cover 22 will suck the hydraulic medium in the sealing cylinder 31, which will return to the sealing cover 22 from top to bottom through the one-way valve 34 on the small flow guide pipe 33, first, the resistance generated when the hydraulic medium flows through the large flow guide pipe 32 and the small flow guide pipe 33 can effectively reduce the speed of the sealing cover 22 when it is pressed down and the ejection speed of the lower pressing plate 21, second, by setting the large flow guide pipe 32 and the small flow guide pipe 33 with different pipe diameters, and cooperating with the different directions of the two one-way valves 34, the speed of the hydraulic medium flowing back into the sealing cover 22 is much smaller than the speed of the hydraulic medium entering the sealing cylinder 31, thereby prolonging the duration of the negative pressure in the sealing cover 22, further reducing the speed of the lower pressing plate 21 when it is ejected and reset, and reducing the invalid distance of the lower pressing plate 21 when it is ejected outward after the rock sample breaks, on the one hand, it improves the stability of the signal collected by the first pressure sensor 211 before and after the rock sample breaks, avoids collecting signals with large fluctuations, and thereby affects the accuracy of the subsequent detection results, on the other hand, it can also protect the first pressure sensor 211 and the first spring 212 and the structure connected thereto, avoiding the problem of structure damage caused by excessive impact force, and achieving the effect of reducing the probability of structure damage.

[0049] The hydraulic medium is a magneto-rheological fluid, the metal coil 37 is arranged at one end of the large flow pipe 32 close to the sealing cylinder 31, and the sealing cylinder 31 is electrically connected with an external controller. By setting the hydraulic medium as a magneto-rheological fluid, and arranging the metal coil 37 electrically connected with the external controller at one end of the sealing cylinder 31 close to the large flow pipe 32, when the metal coil 37 is powered, the electromagnetic field generated near the metal coil 37 will affect the physical properties of the magneto-rheological fluid, so that it is converted from a free-flowing liquid to a Newtonian fluid, causing the hydraulic medium in the sealing cylinder 31 to be unable to flow back into the sealing cover 22 within a short time, so that the duration of the negative pressure in the sealing cover 22 is further prolonged, thereby reducing the fluctuation range of the data collected by the first pressure sensor 211, and improving the accuracy of the data before and after the rock sample is broken.

[0050] The magneto-rheological fluid has the characteristics that it can be instantly (millisecond level) converted from a Newtonian fluid to a Bingham plastic body under the action of a magnetic field, the yield stress changes with the magnetic field strength, and by controlling the current of different coils through a program, the equivalent pore diameter of the throttling channel can be steplessly and quickly adjusted, realizing more accurate flow control than mechanical valves without moving parts.

[0051] The large flow pipe 32 and the small flow pipe 33 penetrate the lower sleeve in the connecting protective sleeve 20 when connecting the sealing cylinder 31, and the penetration position is lower than the lowest point of the upper sleeve, which can ensure that the large flow pipe 32 and the small flow pipe 33 are not hit by the descending upper sleeve when connecting the sealing cylinder 31, improving the safety of the equipment.

[0052] Example Three

[0053] As a further supplement to Example One, as Figures 6-10As shown, the detection table 1 is also provided with a cleaning mechanism 6 for cleaning the surface of the support plate 49 attached with the debris, the cleaning mechanism 6 comprises a third motor 61 fixedly connected to one side of the inner wall of the detection table 1, the top end of the output shaft of the third motor 61 is fixedly connected with a first gear 62, and the first gear 62 is meshedly connected with a second gear 621, the top of the second gear 621 is fixedly connected with a second connecting rod 63, and the top end of the second connecting rod 63 penetrates into the isolation cylinder 8, a second connecting block 631 is arranged above the second gear 621, and the second connecting block 631 is fixedly connected with the inner wall of the detection table 1, the bottom end of the second connecting rod 63 penetrates through the second connecting block 631 and is rotatably connected with the second connecting block 631, the end of the second connecting rod 63 in the isolation cylinder 8 is sleeved with a limiting sleeve 64 and is limitingly and slidably connected with the limiting sleeve 64, and the arc-shaped side wall of the limiting sleeve 64 is fixedly connected with a steel brush 66 parallel to the support plate 49 on one side opposite to the support plate 49, when part of the debris of the rock sample is attached to the support plate 49 under great pressure, the rotation of the support plate 49 alone cannot remove the debris attached to the support plate 49, at this time, the output shaft of the third motor 61 is controlled to drive the first gear 62 to rotate, and the first gear 62 and the second gear 621 are meshedly connected, so as to drive the second gear 621 and the second connecting rod 63 fixedly connected with the top of the second gear 621 to rotate, wherein the second connecting block 631 provides stable support effect for the rotation of the second connecting rod 63, when the second connecting rod 63 rotates, the limiting sleeve 64 limitingly and slidably connected with the top end of the second connecting rod 63 drives the cleaning rod 65 and the steel brush 66 fixedly connected with the cleaning rod 65 to rotate from the place far away from the support plate 49 to above the support plate 49, and the bottom of the steel brush 66 is connected with the surface of the support plate 49, so that the debris attached to the surface of the support plate 49 is removed when the support plate 49 rotates, and the cleaning effect is improved.

[0054] The side wall of the steel brush 66 is fixedly connected with a scraper 67 parallel to the steel brush 66, and the bottom of the scraper 67 is higher than the bottom of the steel brush 66. A third spring 641 is fixedly connected between the inner wall of the limiting sleeve 64 and the top end of the second connecting rod 63. A fixed block 68 is arranged above the limiting sleeve 64 and is fixedly connected with the inner wall of the isolation cylinder 8. The side, opposite to the limiting sleeve 64, of the fixed block 68 is fixedly connected with a first spherical abutting block 69 and a second spherical abutting block 691, respectively. The top of the second spherical abutting block 691 abuts against the lower surface of the fixed block 68. The first spherical abutting block 69 is arranged on the radius of rotation of the second spherical abutting block 691, and the rotation angle between the first spherical abutting block 69 and the second spherical abutting block 691 is 180 degrees. When the steel brush 66 cleans the slag adhered to the support plate 49, some fine slag powder is generated. The centrifugal force generated during the rotation of the support plate 49 is low, and the fine slag powder cannot quickly separate from the surface of the support plate 49. When the fine slag powder cannot be quickly removed by simply relying on the rotating action of the steel brush 66 in cooperation with the cleaning of the support plate 49, the second connecting rod 63 can be rotated to a specified angle by controlling the output shaft of the third motor 61 again. Due to the upward elastic force of the third spring 641 under normal compression, the second spherical abutting block 691 originally in abutment with the lower surface of the fixed block 68 is moved downward. During the rotation of the second connecting rod 63 to the specified angle, the limiting sleeve 64 on the second connecting rod 63 rotates with it. The first spherical abutting block 69 rotates below the first spherical abutting block 69. Since the fixed block 68 is fixedly connected with the isolation cylinder 8, the second spherical abutting block 691 continuously maintains the extrusion state with the first spherical abutting block 69 during the rotation below the first spherical abutting block 69, and is affected by the arc profile of the first spherical abutting block 69. The second spherical abutting block 691 gradually moves downward during the extrusion and limits the sliding of the top end of the second connecting rod 63 downward, and the limiting sleeve 64 extrudes and compresses the third spring 641. During the downward limiting sliding of the top end of the second connecting rod 63, the limiting sleeve 64 drives the steel brush 66 and the scraper 67 on the cleaning rod 65 to move downward by a distance, and the lower surface of the scraper 67 abuts against the support plate 49. The fine slag powder on the surface of the support plate 49 is scraped off by the scraper 67, which facilitates the subsequent detection of the clean and flat surface of the support plate 49 and improves the accuracy of the detection data of the rock sample on the support plate 49.

[0055] Working principle: Before the sample is detected, the supporting plate 49 supporting the rock sample needs to be leveled to improve the accuracy of the detection result. At this time, when the chuck 45 is installed, gaps are arranged between the tray 44 and the chuck 45 and between the chuck block 47 and the limiting block 48 to facilitate the deflection of the supporting plate 49. Then, the first connecting block 52 and the second guide rod 53 are driven to rise and fall by the output shaft of the three cylinders 51, so that the top of the second guide rod 53 abuts against the supporting plate 49 and pushes the deflection of the corresponding side of the supporting plate 49. The rubber layer 46 will be subjected to different forces when the top of the second guide rod 53 presses the supporting plate 49 upward to deflect, and will provide stable support for the deflected supporting plate 49. During the leveling process of the supporting plate 49, the signals collected by the three horizontal sensors 54 are collected by the external controller to assist in controlling the change of the extension amount of the output shaft of the three cylinders 51, so as to control the rapid leveling of the supporting plate 49 and provide a more stable and flat support surface for the subsequent detection of the rock sample, thereby improving the accuracy of the rock hardness detection collection;

[0056] During formal detection, the rock sample is first placed on the supporting seat 13, and then the sealing cover 22 drives the lower pressing plate 21 to move downward. When the lower pressing plate 21 abuts against the rock sample, the sealing cover 22 will gradually approach the lower pressing plate 21 under the continuous downward force. At this time, the first spring 212 fixedly connected between the first pressure sensor 211 and the sealing cover 22 will be compressed and deformed. In this process, the first pressure sensor 211 will continuously collect the pressure signals during the compression process and upload them to the external controller for analysis and calculation, thereby obtaining the hardness detection data of the rock sample during the compression detection process. Specifically, the first motor 28 is started, the worm 27 fixedly connected to the output shaft of the first motor 28 is rotated, and then the worm 27 is engaged with the turbine 26 to drive the turbine 26 to rotate horizontally. At this time, the threaded sleeve 24 fixedly connected with the turbine 26 and the bearing 25 fixedly connected with the bottom end of the threaded sleeve 24 also rotate synchronously with the turbine 26. The support ring 251 fixedly connected with the outer ring of the bearing 25 provides support for the bearing 25. Since the threaded sleeve 24 is threadedly connected with the screw rod 23, when the screw rod 23 and the bottom ends of the three first guide rods 29 are fixedly connected with the sealing cover 22, and the first guide rods 29 are in limiting sliding relationship with the bottom of the installation slot 11, the rotation of the threaded sleeve 24 will drive the screw rod 23 to move vertically, thereby controlling the vertical movement of the sealing cover 22 and the lower pressing plate 21, facilitating the compression detection of rock samples of different heights. While achieving automatic detection according to the height of the rock sample, the device also has the effects of controllable detection stroke, high detection precision and more uniform detection pressure.

[0057] In the detection process, by filling the hydraulic medium with magnetorheological fluid between the sealing cover 22 and the lower pressing plate 21, and using the large flow pipe 32 and the small flow pipe 33 to connect the sealing cover 22 with the sealing cylinder 31, so that the hydraulic medium can flow between the sealing cover 22 and the sealing cylinder 31, when the lower pressing plate 21 abuts against the rock sample, and the sealing cover 22 approaches the lower pressing plate 21, the hydraulic medium in the sealing cover 22 will be extruded by the pressure to enter the sealing cylinder 31 from bottom to top through the one-way valve 34 on the large flow pipe 32, and the hydraulic medium entering the sealing cylinder 31 will again push the piston block 35 connected with the piston in the sealing cylinder 31 to move and compress the second spring 36, thereby increasing the resistance to the entry of the hydraulic medium, reducing the descending speed of the sealing cover 22, making the downward pressure more stable and uniform, thereby improving the accuracy of the signal collected by the first pressure sensor 211, and when the rock sample suddenly breaks, the originally compressed first spring 212 will suddenly rebound and reset, pushing the first pressure sensor 211 and the lower pressing plate 21 to move downward, at this time the negative pressure generated in the sealing cover 22 will suck the hydraulic medium in the sealing cylinder 31, which will return to the sealing cover 22 from top to bottom through the one-way valve 34 on the small flow pipe 33, firstly, the resistance generated when the hydraulic medium flows through the large flow pipe 32 and the small flow pipe 33 can effectively reduce the speed of the sealing cover 22 when it is pressed down and the ejection speed of the lower pressing plate 21, secondly, by setting different pipe diameters of the large flow pipe 32 and the small flow pipe 33, and cooperating with the different directions of the two one-way valves 34, the speed of the hydraulic medium flowing back into the sealing cover 22 is much smaller than the speed of the hydraulic medium entering the sealing cylinder 31, thereby prolonging the duration of the negative pressure in the sealing cover 22, further reducing the speed of the lower pressing plate 21 when it is reset, and reducing the invalid distance of the lower pressing plate 21 when it is ejected outward after the rock sample breaks, on the one hand, it improves the stability of the signal collected by the first pressure sensor 211 before and after the rock sample breaks, avoids collecting signals with large fluctuations, and thereby affects the accuracy of the subsequent detection results, on the other hand, it can also protect the first pressure sensor 211, the first spring 212 and the structural components connected therewith, avoiding the problem of structural damage caused by excessive impact force, thereby reducing the probability of structural damage, secondly, when the external controller supplies power to the metal coil 37, the electromagnetic field generated near the metal coil 37 will affect the physical properties of the magnetorheological fluid, making it change from a free-flowing liquid state to a Newtonian fluid, causing the hydraulic medium in the sealing cylinder 31 to be unable to flow back into the sealing cover 22 in a short time, thereby prolonging the duration of the negative pressure in the sealing cover 22, further reducing the fluctuation range of the data collected by the first pressure sensor 211, and improving the accuracy of the data before and after the rock sample breaks;

[0058] After the detection is completed, the broken rock sample debris scatters on the surface of the support plate 49 and needs to be cleaned before the next rock sample detection. At this time, the second motor 42 is started to rotate the first connecting rod 43 and the tray 44 at the top end of the first connecting rod 43 by the output shaft of the second motor 42. When the tray 44 rotates, the clamping block 47 fixedly connected to the arc-shaped side wall of the tray 44 will abut against the limiting block 48 on the inner wall of the chuck 45 after rotating to a certain angle, and then drive the chuck 45 and the support plate 49 fixedly connected with the chuck 45 to rotate. Under the high-speed rotation of the support plate 49, the debris on the surface of the support plate 49 can be effectively thrown out of the surface of the support plate 49 by the centrifugal force, thereby achieving the effect of automatically cleaning the debris. When part of the debris of the rock sample is bonded to the support plate 49 under a huge pressure, the debris bonded to the support plate 49 cannot be removed simply by the rotation of the support plate 49. At this time, the first gear 62 is driven to rotate by the output shaft of the third motor 61, and the second gear 621 is driven to rotate by the meshing connection relationship between the first gear 62 and the second gear 621, and the second connecting rod 63 fixedly connected to the top of the second gear 621. The second connecting block 631 provides stable support effect for the rotation of the second connecting rod 63. When the second connecting rod 63 rotates, the limiting sleeve 64 limitingly and slidably connected to the top of the second connecting rod 63 will drive the cleaning rod 65 and the steel brush 66 fixedly connected with the cleaning rod 65 to rotate from the place far away from the support plate 49 to above the support plate 49, and make the bottom of the steel brush 66 abut against the surface of the support plate 49, thereby achieving the effect that the debris bonded to the surface of the support plate 49 is removed by the steel brush 66 during the rotation of the support plate 49, and the cleaning effect is improved. When the steel brush 66 cleans the debris bonded to the support plate 49, some fine debris powder will be generated. The centrifugal force generated during the rotation of the support plate 49 is low and cannot quickly separate from the surface of the support plate 49. When the fine debris powder cannot be quickly removed simply by the rotating action of the steel brush 66 in cooperation with the support plate 49, the second connecting rod 63 can be rotated to a specified angle by controlling the output shaft of the third motor 61 again. Since the limiting sleeve 64 is elastically acted on by the third spring 641 in the normal compression state, the second spherical abutment block 691 is in the state of abutting against the lower surface of the fixed block 68. During the rotation of the second connecting rod 63 to the specified angle, the limiting sleeve 64 on the second connecting rod 63 will rotate with it, and the first spherical abutment block 69 will rotate below the first spherical abutment block 69 at this time. Since the fixed block 68 is fixedly connected with the isolation cylinder 8, the second spherical abutment block 691 will continuously maintain the extrusion state with the first spherical abutment block 69 during the rotation below the first spherical abutment block 69, and will gradually move downward in the extrusion state and limitingly slide downward at the top end of the second connecting rod 63,Meanwhile, the limiting sleeve 64 is driven to extrude the third spring 641 to compress and deform, and the second connecting rod 63 slides downward at the top end, in the process, the limiting sleeve 64 drives the steel brush 66 and the scraper 67 on the cleaning rod 65 to move downward by a distance, and the lower surface of the scraper 67 abuts against the support plate 49, the small and broken slag powder on the surface of the support plate 49 is scraped by the scraper 67, the surface of the support plate 49 is kept clean and flat for subsequent detection, and the accuracy of the detection data of the rock sample on the support plate 49 is improved.

[0059] Finally, the bottom of the inner wall of the isolation cylinder 8 is provided as an inclined surface, the inclined sliding slag is guided into the inclined chute of the guide pipe 82 below by the discharge pipe 81, and then is slid into the receiving box 83 through the inclined chute in the guide pipe 82 to be collected, the fallen slag is collected to avoid affecting the safety of the working environment of the equipment, and the clean and sanitary of the working environment of the equipment is ensured.
