Description

Technical Field

[0001] The invention relates to the technical field of rock and soil hardness detection, in particular to a rock and soil hardness detection device for geological survey. Background Art

[0002] Geological survey is an indispensable part of the early stage of engineering construction, which is directly related to the quality and safety of the project. As the main material constituting the foundation, the physical and mechanical properties of rock and soil have a decisive influence on the bearing capacity and stability of the project. Therefore, accurately evaluating the hardness of rock and soil has become a core task in geological survey. It is in this context that rock and soil hardness testing equipment came into being. They use scientific means and methods to accurately measure the hardness of rock and soil, providing reliable data support for engineering design. In addition, with the continuous advancement of engineering technology and the increasing scale of engineering, the requirements for rock and soil hardness testing are also getting higher and higher. Traditional testing methods often have problems such as low accuracy and low efficiency, which are difficult to meet the needs of modern engineering. Therefore, scientific researchers and technicians continue to develop new rock and soil hardness testing equipment to improve detection accuracy and efficiency.

[0003] Existing geological survey rock and soil hardness testing equipment often uses a horizontal testing table during use. The rock and soil materials to be tested are placed on the horizontal table and a certain pressure is applied downward. However, in this testing method, the rock and soil materials to be tested may slip during the downward pressure, affecting the smooth progress of the test, or part of the rock and soil materials may be broken during the pressure application, causing the entire rock and soil materials to tilt. At this time, when the downward pressure continues, the pressure application part will deviate from the center position of the rock and soil materials. In this case, not only will the rock and soil materials slip or splash significantly during the continuous pressure application, posing a major safety hazard, but the test results may also be inaccurate. In addition, the horizontal testing table also has the problem of difficulty in removing broken waste materials. Therefore, in view of the above situation, there is an urgent need to develop a geological survey rock and soil hardness testing equipment to overcome the shortcomings in current practical applications.

DETAILED DESCRIPTION

[0052] 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.

[0053] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0054] See also Figure 1-Figure 10 The embodiment of the present invention provides a geological survey rock and soil hardness detection device, including a base plate 1, and also includes:

[0055] A detection bracket 2, the detection bracket 2 is fixedly mounted on the base plate 1, and the detection bracket 2 is also fixedly mounted with a hardness detection box 3, and a discharge control box 5 is fixedly mounted on the hardness detection box 3, and the discharge control box 5 is connected to the detection bracket 2;

[0056] and a hardness detection mechanism, which is respectively connected to the base plate 1, the hardness detection box 3 and the material discharge control box 5, wherein the hardness detection mechanism includes a lateral extrusion drive component, a detection extrusion plate 21 and a limit feeding component;

[0057] The lateral extrusion drive assembly is connected to the base plate 1 and the hardness detection box 3 respectively, and two detection extrusion plates 21 are arranged on the lateral extrusion drive assembly. The position-limiting feeding assembly is connected to the discharge control box 5 and is located above the two detection extrusion plates 21.

[0058] The two detection extrusion plates 21 are symmetrical about the middle part of the hardness detection box 3, and each of the detection extrusion plates 21 is provided with a hardness detection part 22. During the detection of geotechnical materials, the lateral extrusion drive assembly drives the two detection extrusion plates 21 to rotate synchronously, and the rotation directions are opposite. At the same time, the limiting feeding assembly limits the top of the geotechnical material.

[0059] See also Figure 1-Figure 10 , further comprising: a feed port 4, the feed port 4 being opened on the side wall of the discharge control box 5;

[0060] And a waste discharge port 15 , which is opened on the side wall of the hardness testing box 3 , wherein a waste collection bin 8 is also fixedly installed on the hardness testing box 3 , and the waste collection bin 8 is arranged close to the waste discharge port 15 .

[0061] When it is necessary to perform hardness testing on geotechnical materials, first, the geotechnical materials to be tested can be placed through the feed port 4 onto the limit feeding assembly in the discharge control box 5. At this time, the limit feeding assembly drives the geotechnical materials to be tested to move downward into the hardness testing box 3 and is located between the two detection extrusion plates 21, wherein the space between the two detection extrusion plates 21 is the detection space. After the geotechnical materials reach the detection space, as the limit feeding assembly continues to drive the geotechnical materials to be tested to move downward, the geotechnical materials to be tested will contact the hardness detection part 22. At this time, the geotechnical materials will be firmly placed in the detection space and protected by the hardness testing box 3, the discharge control box 5 and the limit feeding assembly. Under the action, the whole hardness testing process is in a protected state to avoid flying stones or particles endangering related equipment and personnel. Then, the lateral extrusion drive component is started, and the lateral extrusion drive component will drive the two detection extrusion plates 21 to rotate synchronously, and the rotation directions are opposite, so that the hardness detection part 22 can extrude the rock and soil materials. During the extrusion process, the hardness of the rock and soil materials can be detected (the detection method can adopt the existing detection technology, and can also adopt the method of distributing multiple sensors on the hardness detection part 22 and data fitting to accurately measure the pressure at different positions to ensure the accuracy of the detection results, which will not be elaborated here), and as the two detection extrusion plates 21 rotate, The lower part of the two detection extrusion plates 21 is changed from the original blocked state to the open state (at this time, the geotechnical material is approximately in a suspended state), and the generated fragments or particles will fall downward under the action of their own gravity, and flow through the waste discharge port 15 to the waste collection bin 8 for storage (wherein, the waste discharge port 15 is an inclined structure, one end of the waste discharge port 15 extends to the middle of the hardness detection box 3, and the other end is connected to the waste collection bin 8, so that when the generated fragments or particles fall to the middle of the hardness detection box 3 during the detection process, they will slide through the waste discharge port 15 to the waste collection bin 8, which will not be elaborated here), so that the staff can carry out centralized processing later, thereby solving the problem of particles or fragments. In order to solve the problem of difficulty in removing waste materials, after the hardness test is completed, each component is restored to its original position, and the same hardness test operation is carried out on the next geotechnical material to achieve the purpose of improving the accuracy of the test results. The operation is simple. Due to the lateral extrusion method and the limit on the top of the geotechnical material, the geotechnical material can be prevented from slipping to the side during the hardness test, and the pressure-applied part can be prevented from deviating from the center position of the geotechnical material, which will lead to deviations in the test results. This is conducive to ensuring the smooth progress of the test work, and can also reduce the probability of safety accidents during the test process. It is also convenient for the staff to collect and process waste materials such as fragments and particles after the test, providing convenience for the staff.

[0062] In one embodiment of the present invention, see Figure 1-Figure 10 , the lateral extrusion drive assembly comprises:

[0063] Detection rotating rod 1 9 and detection rotating rod 2 14, both of which are rotatably connected to the hardness detection box 3, and both of which are provided with a plurality of support blocks 19, and the support blocks 19 are fixedly connected to the detection extrusion plate 21;

[0064] A transmission connecting rod 18, one end of which is fixedly connected to the middle portion of the detection rotating rod 9;

[0065] An extrusion drive member 16, wherein the extrusion drive member 16 is fixedly mounted on the base plate 1, and a push-pull movable rod 17 is fixedly mounted on the output end of the extrusion drive member 16, and one end of the push-pull movable rod 17 is rotatably connected to the other end of the transmission connecting rod 18;

[0066] And a transmission unit, wherein the transmission unit is connected to the detection rotating rod 1 9 and the detection rotating rod 2 14 respectively.

[0067] The transmission unit comprises:

[0068] A transmission plate 10, one end of which is fixedly connected to the detection rotating rod 9, and the other end of which is provided with a movable notch 12;

[0069] A transmission plate 13, one end of which is fixedly connected to the detection rotating rod 14;

[0070] And a linkage column 11, wherein the linkage column 11 is fixedly connected to the other end of the transmission plate 2 13, and the linkage column 11 is also inserted into the movable slot 12 and movably connected to the movable slot 12.

[0071] It also includes: a side protection plate 20 , the number of the side protection plates 20 is two, the two side protection plates 20 are respectively fixedly connected to the two support blocks 19 , and are respectively located at the two ends of the detection extrusion plate 21 .

[0072] It also includes: a position limiting reinforcement plate 24, the number of the position limiting reinforcement plates 24 is multiple, and the multiple position limiting reinforcement plates 24 are respectively installed on the bottom of the two detection and extrusion plates 21;

[0073] The two adjacent limiting reinforcement plates 24 on the bottom of the two detection extrusion plates 21 are cross-arranged, and a discharge port 25 is formed between the two adjacent limiting reinforcement plates 24 .

[0074] After the geotechnical material to be tested is moved to the testing space (wherein the size of the geotechnical material is larger than the distance between the testing rotating rod 1 9 and the testing rotating rod 2 14, the staff can select a suitable geotechnical sample for testing before the testing operation, which will not be described in detail here), the extrusion driving member 16 is started, wherein the extrusion driving member 16 can be in the form of a hydraulic cylinder, the extrusion driving member 16 will push the push-pull movable rod 17 to move, and push the transmission connecting rod 18 to move synchronously, and during the movement of the transmission connecting rod 18, it will drive the detection rotating rod 1 9 to rotate counterclockwise (such as Figure 5As shown in the figure, during the rotation of the detection rotating rod 19, the transmission plate 10 will be driven to rotate synchronously, and the transmission plate 10 will drive the transmission plate 2 13 and the detection rotating rod 2 14 to rotate clockwise through the linkage column 11. Under the action of the detection rotating rod 19 and the detection rotating rod 2 14 rotating synchronously and in opposite directions, the two detection extrusion plates 21 can be driven to rotate synchronously through the support block 19, so that the two hardness detection parts 22 can extrude the geotechnical material. At the same time, under the limiting action of the limiting feeding assembly on the top of the geotechnical material, the geotechnical material is prevented from moving upward during the lateral extrusion process. In addition, by setting two side protection The plate 20 can limit the other two side parts of the geotechnical material and prevent the flying fragments from hitting the inner wall of the hardness testing box 3, thereby extending the service life of the equipment. A notch is provided on the side protection plate 20, which can prevent the detection rotating rod 21 from interfering with the movement of the side protection plate 20 during the rotation of the two detection extrusion plates 21. No further details are given here. In addition, by engaging with each other through the multiple limit reinforcement plates 24, relative sliding occurs between adjacent limit reinforcement plates 24 during the rotation of the two detection extrusion plates 21, thereby preventing the two detection extrusion plates 21 from moving only in the rotation direction. The two detection extrusion plates 21 are movable to avoid relative movement during the extrusion of the geotechnical material, which is beneficial to improving the structural strength of the equipment and ensuring the smooth progress of the extrusion process. During the relative sliding of the adjacent limiting reinforcement plates 24, the size of the discharge port 25 is gradually increased, so that during the extrusion process, the broken pieces and particles on the geotechnical material can smoothly fall to the waste discharge port 15 through the discharge port 25. The number and size of the limiting reinforcement plates 24 are set according to actual needs and will not be described in detail here. After the extrusion test is completed, there are still large unbroken pieces (at this time, the pieces of the pieces The size is smaller than the distance between the two detection extrusion plates 21 when the detection extrusion plates 21 are in a vertical state), and the limiting reinforcement plates 24 set at the bottom of the two detection extrusion plates 21 can be completely separated under the continuous pushing action of the extrusion driving member 16 (because the detection extrusion plates 21 are not subjected to the reaction force of the geotechnical materials at this time, it is not necessary for the limiting reinforcement plates 24 to engage with each other to achieve the stability of the rotation of the detection extrusion plates 21), so that all the waste materials such as fragments and particles in the space between the two detection extrusion plates 21 (that is, in the detection space) can be completely discharged, so that the staff can collect and centrally process them, which provides convenience for the staff.

[0075] In one embodiment of the present invention, see Figure 1-Figure 10 , the position limiting feeding assembly comprises:

[0076] A telescopic cylinder 6, wherein the telescopic cylinder 6 is fixedly mounted on the material discharge control box 5, and a lifting slide 26 is fixedly mounted on the output end of the telescopic cylinder 6, and the lifting slide 26 is slidably connected to the inner wall of the material discharge control box 5;

[0077] Sliding columns 29, the number of the sliding columns 29 is two, the two sliding columns 29 are fixedly connected to the lifting slide plate 26, and a protective limit plate 27 is slidably mounted on the sliding columns 29;

[0078] A return spring 30, wherein the return spring 30 is sleeved on the sliding column 29, and the two ends of the return spring 30 are respectively fixedly connected to the lifting slide plate 26 and the protective limit pressure plate 27;

[0079] and a supporting unit, wherein the supporting unit is connected to the sliding column 29 and is located between the two detection extrusion plates 21 .

[0080] It also includes: an anti-skid detection portion 33, which is located on the bottom wall of the protective limit pressure plate 27 and above the two detection extrusion plates 21;

[0081] And a limiting notch 23 , the limiting notch 23 is opened on the detection extrusion plate 21 , and the limiting notch 23 is also slidably connected to the protection limiting pressure plate 27 .

[0082] The support unit comprises:

[0083] A feeding support plate 31, wherein the feeding support plate 31 is fixedly connected to the bottom ends of the two sliding columns 29;

[0084] A feed opening 34, wherein the number of the feed openings 34 is multiple, and the multiple feed openings 34 are evenly opened on the feed support plate 31;

[0085] and an inverted V-shaped portion 35 , wherein the inverted V-shaped portion 35 is disposed on the feeding support plate 31 and is disposed close to the top of the discharge port 34 .

[0086] See also Figure 1-Figure 10 , further comprising: a cleaning fan 7, wherein the cleaning fan 7 is fixedly mounted on the discharge control box 5;

[0087] A transmission hose 28, one end of which is connected to the output end of the cleaning blower 7, and the other end of which is connected to the protective limit plate 27;

[0088] And a nozzle 32, the number of the nozzle heads 32 is multiple, the multiple nozzle heads 32 are all fixedly connected to the protective limiting pressure plate 27, and are connected to the transmission hose 28, and the multiple nozzle heads 32 are all arranged on the protective limiting pressure plate 27 in an inclined manner.

[0089] In the early stage of hardness testing of geotechnical materials, the geotechnical materials to be tested are first placed on the feeding support plate 31 in the discharge control box 5 through the feed port 4. At this time, the geotechnical materials are located between the feeding support plate 31 and the protective limit pressure plate 27 (the protective limit pressure plate 27 has not yet contacted the top of the geotechnical materials, but the two are very close to each other. In addition, the side of the geotechnical materials is also very close to the hardness testing part 22, and the width of the feeding support plate 31 is smaller than the distance between the lower parts of the two detection extrusion plates 21 when the detection extrusion plates 21 are in an inclined state, so as to avoid interference with the downward movement of the feeding support plate 31). Starting the telescopic cylinder 6 can push the lifting slide plate 26 to slide slowly downward in the discharge control box 5, and push the sliding column 29 and the feeding support plate 31 to move downward synchronously, and the geotechnical materials also move downward. After moving a short distance, the side of the geotechnical material contacts the hardness detection part 22. At this time, the telescopic cylinder 6 continues to push the lifting slide plate 26 downward, and the feeding support plate 31 will be separated from the bottom of the geotechnical material (after the side of the geotechnical material contacts the hardness detection part 22 and the protective limit pressing plate 27 is pressed on the top of the geotechnical material, the hardness detection work can be carried out. At this time, the feeding support plate 31 does not need to be moved down again. In addition, during the entire extrusion process, especially in the initial stage, there is still enough space between the feeding support plate 31 and the limit reinforcing plate 24. Therefore, during the detection process, the feeding support plate 31 is always located between the two detection extrusion plates 21 and located at the upper position of the limit reinforcing plate 24, avoiding the limit reinforcing plate 24 in the initial stage of detection. The fixed plate 24 interferes with the downward movement of the feeding support plate 31, which will not be described in detail here). The inverted V-shaped portion 35 can be used to detect whether the two are separated smoothly (a pressure sensor can be provided on the inverted V-shaped portion 35, which will not be described in detail here). In addition, the set feed opening 34 and the inverted V-shaped portion 35 can also ensure that the fragments and particles generated during the extrusion process fall smoothly. As the lifting slide plate 26 drives the protective limit pressure plate 27 to continue to move downward, when the feeding support plate 31 is separated from the bottom of the geotechnical material, the anti-slip detection portion 33 on the protective limit pressure plate 27 also contacts the top of the geotechnical material (in the process of the protective limit pressure plate 27 moving downward, the protective limit pressure plate 27 mainly plays a protective function, and the protective limit pressure plate 27 will slide in the limit notch 23 , thereby ensuring the smooth downward movement of the protective limit pressure plate 27), and under the detection action of the anti-slip detection part 33, the reset spring 30 is in a certain compression state, thereby ensuring that the geotechnical material cannot move upward during the lateral extrusion of the geotechnical material. In addition, when the lateral extrusion force is too large, the geotechnical material can slide upward for a distance under the buffering action of the reset spring 30 to avoid damage to the equipment due to excessive extrusion force. At the same time, the anti-slip detection part 33 can also perform detection during the lateral extrusion of the geotechnical material (existing detection technology can also be used) and record the data to provide auxiliary support in the subsequent calculation and analysis of the detection results to ensure the accuracy of the detection results. No more details are given here. After the detection is completed,With the continuous pushing action of the extrusion drive 16, the limiting reinforcement plates 24 set at the bottom of the two detection extrusion plates 21 can be completely separated, so that all the debris and particles and other waste materials in the space between the two detection extrusion plates 21 can be completely discharged. At the same time, the cleaning fan 7 is started to transport the high-pressure air to the nozzle 32 through the transmission hose 28, and the hardness detection part 22 on the detection extrusion plate 21 is blown and cleaned (at this time, the protective limiting pressure plate 27 drives the bottom of the limiting notch 23 to block the upper part of the detection extrusion plate 21, so that the high-pressure gas can be completely sprayed downward, which is conducive to improving the cleaning effect), avoiding small particles of geotechnical materials from adhering to the hardness detection part 22, thereby affecting the results of subsequent detection of other geotechnical materials, and ensuring the cleanliness of the surface of the hardness detection part 22, so that all waste materials are discharged into the waste collection bin 8, which provides convenience for the staff.
