Description

Technical Field

[0001] The present invention relates to the technical field of soft rock content test and detection, and particularly relates to a soft rock content test detector. Background Art

[0002] Soft rock particles refer to rock particles with a particle size range of 0.075 - 50 mm, usually having low strength and high compressibility. Soft rock particles have an important impact on the design and construction of geotechnical engineering. Accurately determining the content of soft rock particles in soil is of great significance for evaluating the engineering properties of geotechnical bodies and designing reasonable foundations.

[0003] Currently, the commonly used detection method for soft rock particle content is as follows: classify the inspected stones according to the particle size range, and then apply corresponding pressures to the classified stones one by one. Stones in the same particle size range are applied with the same magnitude of force, and stones in different particle size ranges are applied with different forces. The crushed stones are soft rocks, and the mass ratio of soft rocks to all stones is the soft rock particle content.

[0004] Currently, the pressure applied to the aggregate in the domestic test for detecting the soft rock content of the aggregate is mechanical pressure, resulting in unstable pressure application, an unstable pressure application platform, inability to achieve level parallelism, different stress conditions for soft rock particles on the platform, and increased detection errors. Secondly, the existing equipment has no effective protection. When the aggregate test material is damaged, the instantaneous impact force is large, resulting in the cracking of the aggregate and easy occurrence of phenomena such as debris splashing, which not only easily causes harm to the surrounding personnel but also increases the cleaning workload of the staff. Summary of the Invention

[0005] The purpose of the present invention is to provide a soft rock content test detector to solve the deficiencies in the prior art. It has high flexibility, ensures uniform stress on the stone samples in the moving platform during the test, reduces test errors, and can prevent the stone samples in the moving platform from splashing out when broken during the test, improving operation safety and reducing the subsequent cleaning workload of personnel.

[0006] The present invention provides a soft rock content test detector, which includes a base and a top plate provided on the top of the base. The base and the top plate are connected by four columns, and a soft rock content test detection component is provided between the base and the top plate.

[0007] The soft rock content test detection component includes a hydraulic cylinder, a moving platform component, and a stone pressing component arranged in sequence from bottom to top. The hydraulic cylinder is fixed on the top of the base, the moving platform component is arranged on the top of the hydraulic cylinder, and the stone pressing component is arranged at the bottom end of the top plate. A hydraulic device is used to apply pressure, with stable pressure application, pressure holding, and no pressure drop.

[0008] An adjustment component is provided between the hydraulic cylinder and the moving platform assembly for adjusting the position of the moving platform assembly to ensure uniform stress on the stone samples in the moving platform during the test and reduce test errors.

[0009] A splash-proof component is provided outside the stone pressing component to prevent the stone samples from breaking and splashing during the test, improving operation safety and reducing the subsequent cleaning workload of personnel.

[0010] As described above, in a soft stone content test detector, preferably, the moving platform assembly includes a moving platform for placing stone samples. One side of the moving platform is fixedly connected and communicated with a connecting frame. The side of the connecting frame away from the moving platform is rotatably connected with a threaded cylinder. A threaded rod passes through the moving platform, the connecting frame and the threaded cylinder. The threaded rod is threadedly connected with the threaded cylinder, and one end of the threaded rod is fixed with a push plate, which can automatically take out the stone samples after the test.

[0011] An opening adapted to the size of the push plate is formed on the side of the moving platform away from the connecting frame. A side cover plate covering the opening is provided on the side of the moving platform away from the connecting frame. The top of the side cover plate is hinged to the outer wall of the moving platform through a spring hinge. The spring hinge automatically applies a reverse force through the built-in compression or tension spring after the door leaf is opened to make it close smoothly without manual operation. Therefore, the use of a spring hinge can realize the automatic opening and closing of the side cover plate.

[0012] A gear is fixed on the outer wall of the threaded cylinder. A driving component for driving the threaded cylinder to rotate is provided outside the threaded cylinder. The driving component includes a rack meshing with the gear. An outer frame is provided outside the rack. The top of the outer frame is fixed to the bottom end of the top plate. The top end of the rack is slidably connected to the bottom end of the top plate through a slide rail. One side of the rack away from the gear is connected to the inner wall of the outer frame through at least one spring one.

[0013] When the hydraulic cylinder drives the moving platform assembly to rise and the stone pressing component tests the stone samples in the moving platform, the push plate enters the connecting frame. When the hydraulic cylinder drives the moving platform assembly to descend and the stone pressing component leaves the moving platform assembly, the push plate pushes out the tested stone samples from the opening. A material guiding groove for guiding the stone samples is fixed at the bottom of the side of the moving platform away from the connecting frame. The material guiding groove is arranged at the bottom of the opening and the side cover plate.

[0014] The stone pressing component includes a force transmission rod. A pressing plate adapted to the internal size of the moving platform is fixed at the bottom end of the force transmission rod. A sensor is fixed at the top end of the force transmission rod. The sensor adopts a digital display pressure sensor, with clear data visible and an accuracy of 0.1N, which has higher accuracy and reduces test errors.

[0015] The splash-proof component includes a top cover plate slidably arranged on the outer wall of the force transmission rod. The four corners of the top of the top cover plate are connected to the bottom of the top plate through the second springs. A sealing gasket is fixed to the bottom of the top cover plate, and the sealing gasket is arranged on the outer wall of the force transmission rod. An expansion rod is arranged inside each second spring, and the two ends of the expansion rod are respectively fixed to the top of the top cover plate and the bottom of the top plate, and are used for guiding the up and down movement of the top cover plate.

[0016] When the hydraulic cylinder drives the moving platform component to rise so that the stone pressing component tests the stone sample in the moving platform, the moving platform contacts and presses the second springs with the top cover plate, so that the top cover plate seals the top of the moving platform to prevent the stone sample in the moving platform from being broken and splashed during the test.

[0017] The adjustment component includes a first platform and a second platform arranged on the top of the first platform. The second platform is arranged at the bottom of the moving platform. An X-direction linear module for driving the second platform to move along the X-axis is fixed to the top of the first platform, and a Y-direction linear module for driving the moving platform to move along the Y-axis is fixed to the top of the second platform.

[0018] Installation grooves one are respectively formed at the four corners of the top of the moving platform, and an infrared receiver is fixed in each installation groove one. Installation grooves two are respectively formed at the four corners of the bottom of the top cover plate. The installation grooves two are arranged outside the sealing gasket, and an infrared transmitter is fixed in each installation groove two. The infrared transmitters correspond to the infrared receivers at their bottoms one by one, and are used for positioning the position of the moving platform.

[0019] A feeding component is arranged on one side of the moving platform component and the stone pressing component. The feeding component includes a fixed outer pipe fixed to the bottom of the top plate. A movable inner pipe is arranged at one end of the fixed outer pipe away from the top plate. One end of the movable inner pipe extends into the fixed outer pipe and is slidably connected with the fixed outer pipe.

[0020] The outer wall of the movable inner pipe is connected to the end of the fixed outer pipe away from the top plate through at least one third spring. A feeding hopper is fixed to the top of the top plate. The end of the fixed outer pipe close to the top plate is communicated with the bottom end of the feeding hopper. The top and bottom of the end of the movable inner pipe away from the fixed outer pipe are both processed into inclined surfaces.

[0021] A spirit level is fixed to the top of the connecting frame, and leveling feet are respectively fixed to the four corners of the bottom of the base. By finely adjusting the height of the leveling feet, the equipment can be kept level according to the spirit level. A control screen is fixed to the top of the top plate.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Before the test, by finely adjusting the height of the leveling feet, the moving platform can be kept level. By finely adjusting the X and Y axis positions of the moving platform through the X-direction linear module and the Y-direction linear module, the centering flexibility is high, ensuring that the stone sample in the moving platform is evenly stressed during the test and reducing the test error;

[0024] 2. During the test, the top cover plate of the splash-proof component can seal the top of the moving platform, preventing the stone samples in the moving platform from splashing out when they are broken during the test, improving the operation safety and reducing the subsequent cleaning workload of personnel.

[0025] 3. After the test, while the moving platform component descends and resets, the push plate can automatically take out the stone samples after the test in the moving platform. On the one hand, it replaces manual taking out, improving the test efficiency of the whole batch of stones. On the other hand, it can reduce the risk of danger when personnel clean between the moving platform and the stone pressing component. Description of the Drawings

[0048] The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] Embodiment 1 of the present invention: As Figures 1 - 5 and Figure 8 shown, the present invention provides a soft stone content test detector, including a base 1 and a top plate 2 provided on the top of the base 1. A control panel 12 for controlling the electrical equipment of the present invention is fixed at the top end of the top plate 2.

[0050] The base 1 and the top plate 2 are connected by four support pillars 3. A soft stone content test and detection assembly is provided between the base 1 and the top plate 2. The soft stone content test and detection assembly includes a hydraulic cylinder 4, a moving platform assembly 5, and a stone pressing assembly 6 arranged in sequence from bottom to top. The hydraulic cylinder 4 is fixed on the top of the base 1, the moving platform assembly 5 is arranged on the top of the hydraulic cylinder 4, and the stone pressing assembly 6 is arranged at the bottom end of the top plate 2.

[0051] The mobile platform component 5 includes a mobile platform 51 for placing stone samples. The stone pressing component 6 includes a force transmission rod 61. At the bottom end of the force transmission rod 61, a pressing plate 62 adapted to the internal dimensions of the mobile platform 51 is fixed. At the top end of the force transmission rod 61, a sensor 63 is fixed. The sensor 63 is a digital display pressure sensor, and the data is displayed on the control screen 12.

[0052] During use, place the stone sample in the mobile platform 51. The hydraulic cylinder 4 drives the mobile platform 51 to move upward, so that the pressing plate 62 enters the mobile platform 51 to extrude the stone sample. The sensor 63 detects the pressure and transmits it to the control screen 12 for display. Until the pressure is applied to a fixed pressure value, then the hydraulic cylinder 4 drives the mobile platform 51 to reset, count the broken stones, and then calculate the weight ratio of the broken stones to the unbroken stones, so as to obtain the soft stone content.

[0053] In this embodiment, a hydraulic device is used to apply pressure, with stable pressure application, pressure holding and no pressure drop. And by using a digital display sensor, the data is clearly visible, with an accuracy of 0.1 N, higher accuracy, and reduced test errors.

[0054] Embodiment 2 of the present invention: As Figure 1 、 Figure 2 and Figure 8 shown, in order to prevent the stone sample in the mobile platform component 5 from splashing when it breaks during the test, in this embodiment, a splash-proof component 9 is provided outside the stone pressing component 6. The splash-proof component 9 includes a top cover plate 91 slidably arranged on the outer wall of the force transmission rod 61. At the four corners of the top end of the top cover plate 91, both ends are connected to the bottom end of the top plate 2 through springs two 92. A sealing gasket 93 is fixed to the bottom end of the top cover plate 91, and the sealing gasket 93 is arranged on the outer wall of the force transmission rod 61; an expansion rod is arranged inside each spring two 92, and both ends of the expansion rod are respectively fixed to the top end of the top cover plate 91 and the bottom end of the top plate 2. The expansion rod is used to guide the up and down movement of the top cover plate 91.

[0055] When the hydraulic cylinder 4 drives the mobile platform component 5 to rise so that the stone pressing component 6 tests the stone sample in the mobile platform 51, the mobile platform 51 contacts and presses the spring two 92 with the top cover plate 91, realizing that during the test process, the top cover plate 91 seals the top end of the mobile platform 51, thereby preventing the stone sample in the mobile platform 51 from splashing outward when it breaks during the test, improving the operation safety, and also reducing the subsequent cleaning workload of personnel.

[0056] Embodiment 3 of the present invention: As Figures 1 - 5 and Figure 8 shown, leveling feet 11 are fixed to the four corners of the bottom end of the base 1. The leveling feet 11 are mainly used to maintain the horizontal stability of the equipment by adjusting the height, and are an adjustment device widely used in industrial equipment, furniture, household appliances and other fields. One side of the mobile platform 51 is fixedly connected and communicated with a connecting frame 52, and a spirit level 512 is fixed to the top end of the connecting frame 52.

[0057] An adjustment assembly 7 is provided between the hydraulic cylinder 4 and the moving platform assembly 5 for adjusting the position of the moving platform assembly 5. The adjustment assembly 7 includes a first platform 71 and a second platform 72 provided on the top of the first platform 71. The second platform 72 is provided at the bottom of the moving platform 51. An X-axis linear module 73 for driving the second platform 72 to move along the X-axis is fixed to the top of the first platform 71, and a Y-axis linear module 74 for driving the moving platform 51 to move along the Y-axis is fixed to the top of the second platform 72.

[0058] Installation grooves 510 are provided at the four corners of the top end of the moving platform 51, and an infrared receiver 511 is fixed in each installation groove 510. Installation grooves 94 are provided at the four corners of the bottom end of the top cover plate 91. The installation grooves 94 are provided outside the sealing gasket 93, and an infrared transmitter 95 is fixed in each installation groove 94 for positioning the position of the moving platform 51.

[0059] Before the test, it is necessary to adjust the position and angle of the moving platform 51 to ensure uniform force on the stone sample. The specific adjustment operation is as follows:

[0060] By finely adjusting the height of the leveling feet 11 and keeping the device level according to the spirit level 512, the moving platform 51 can be kept level. By finely adjusting the positions of the moving platform 51 in the X-axis and Y-axis directions through the X-axis linear module 73 and the Y-axis linear module 74 until the infrared rays emitted by each infrared transmitter 95 can be received by the infrared receiver 511 at its bottom and the signal is transmitted to the control screen 12, it indicates that the moving platform 51 is successfully centered. This ensures uniform force on the stone sample in the moving platform 51 during the test and reduces the test error.

[0061] Example 4 of the present invention: As Figures 1 - 7 shown, a threaded cylinder 53 is connected to the side of the connecting frame 52 away from the moving platform 51. The connecting frame 52 and the threaded cylinder 53 are rotationally connected through a bearing. A threaded rod 54 passes through the moving platform 51, the connecting frame 52 and the threaded cylinder 53. The threaded rod 54 is threadedly connected to the threaded cylinder 53, and a push plate 55 is fixed to one end of the threaded rod 54. The front and rear sides of the push plate 55 are in contact with the front and rear inner walls of the moving platform 51 for restricting the rotation of the push plate 55 and the threaded rod 54.

[0062] An opening 56 that matches the size of the push plate 55 is provided on the side of the mobile platform 51 away from the connecting frame 52. A side cover 57 covering the opening 56 is provided on the side of the mobile platform 51 away from the connecting frame 52, and the top of the side cover 57 is hinged to the outer wall of the mobile platform 51 by a spring hinge to facilitate automatic opening and closing of the side cover 57. A material guide trough 58 for guiding stone samples is fixed to the bottom of the side of the mobile platform 51 away from the connecting frame 52, and the material guide trough 58 is provided at the opening 56 and the bottom of the side cover 57.

[0063] A gear 59 is fixed to the outer wall of the threaded barrel 53 . A driving assembly 8 for driving the threaded barrel 53 to rotate is provided outside the threaded barrel 53 . The driving assembly 8 includes a rack 81 meshing with the gear 59 .

[0064] When the hydraulic cylinder 4 drives the mobile platform assembly 5 to rise and the stone pressing assembly 6 tests the stone sample in the mobile platform 51, the gear 59 moves up and rotates along the rack 81, driving the threaded barrel 53 to rotate, causing the threaded rod 54 to move left and drive the push plate 55 to enter the connecting frame 52, as shown in FIG. Figure 13 As shown, at this time, the push plate 55 does not hinder the movement of the pressure plate 62;

[0065] After the test, the hydraulic cylinder 4 drives the mobile platform assembly 5 to descend so that the stone pressing assembly 6 leaves the mobile platform 51, and the gear 59 moves down along the rack 81 and rotates, driving the threaded barrel 53 to reverse, so that the threaded rod 54 drives the push plate 55 to move rightward to push the tested stone sample in the mobile platform 51, and the side cover 57 is pushed open. Figure 11 and 12 As shown, the stone sample falls from the opening 56 into the guide trough 58 . A person may place a tray at the top of the base 1 at the bottom of the guide trough 58 to hold the stone sample.

[0066] This embodiment realizes the automatic removal of stone samples after testing in the mobile platform 51. On the one hand, it replaces manual removal and improves the testing efficiency of the entire batch of stones. On the other hand, it can reduce the risk of danger when people put their hands between the mobile platform 51 and the stone pressing assembly 6 for cleaning.

[0067] Furthermore, in order to prevent the gear 59 from being unable to mesh with the rack 81 due to the movement of the mobile platform 51, Figure 6 and Figure 7 As shown, an outer frame 82 is provided outside the rack 81, the top end of the outer frame 82 is fixed to the bottom end of the top plate 2, the top end of the rack 81 is slidably connected to the bottom end of the top plate 2 via a slide rail, and the side of the rack 81 away from the gear 59 is connected to the inner wall of the outer frame 82 via at least one spring 83;

[0068] If the length of the gear 59 in the X direction is designed to be greater than the length of the rack 81 in the X direction, it can ensure that the gear 59 can always remain engaged with the rack 81 when the moving platform 51 is finely adjusted in the X direction. At the same time, the elastic force of the first spring 83 can ensure that the gear 59 can always remain engaged with the rack 81 when the moving platform 51 is finely adjusted in the Y direction.

[0069] Embodiment 5 of the present invention: As Figure 1 , Figure 2 , Figure 9 and Figure 10 shown, on one side of the moving platform assembly 5 and the stone pressing assembly 6, there is a feeding assembly 10. The feeding assembly 10 includes a fixed outer tube 101 fixed to the bottom end of the top plate 2. One end of the fixed outer tube 101 away from the top plate 2 is provided with a movable inner tube 102. One end of the movable inner tube 102 extends into the fixed outer tube 101 and is slidably connected to the fixed outer tube 101; the outer wall of the movable inner tube 102 and one end of the fixed outer tube 101 away from the top plate 2 are connected by at least one third spring 103. A feeding hopper 104 is fixed to the top end of the top plate 2. One end of the fixed outer tube 101 close to the top plate 2 is communicated with the bottom end of the feeding hopper 104; the top and bottom of the end of the movable inner tube 102 away from the fixed outer tube 101 are both processed into inclined surfaces.

[0070] During the test, the hydraulic cylinder 4 drives the moving platform assembly 5 to rise so that the moving platform 51 contacts the inclined surface of the movable inner tube 102. As Figure 12 shown, personnel can put the stone sample into the feeding hopper 104. Then the stone sample enters the moving platform 51 along the fixed outer tube 101 and the movable inner tube 102. Then the hydraulic cylinder 4 continues to drive the moving platform 51 to move up for the stone sample test. Then the moving platform 51 pushes the movable inner tube 102, causing the movable inner tube 102 to enter the fixed outer tube 101 and compress the third spring 103, so that the movable inner tube 102 can reset later, as Figure 13 shown.

[0071] This embodiment avoids putting hands between the stone pressing assembly 6 and the moving platform 51 during manual feeding, reducing the risk of injury to the hands of personnel caused by the combination of the moving platform 51 and the pressing plate 62 due to equipment failure.
