Description

Technical Field

[0001] The invention relates to the field of road detection, and in particular to a detection device for municipal road concrete strength and a control system thereof. Background Art

[0002] In the field of this technical field, the strength testing method for municipal roads is to use a concrete coring machine for testing. The coring machine rotates in the concrete through an internal drill bit and takes out the core block. The concrete coring machine is an engineering testing equipment, which is widely used in highways, airports, ports, docks, dams and other places. It is used for coring cement concrete and asphalt concrete for compression, flexural and other tests.

[0003] At present, the existing coring machines adopt a semi-automatic method. After drilling and sampling, workers are required to manually remove the sample core blocks from the inside of the drill bit or the borehole. The operation is more cumbersome, and there is insufficient protection for the sample core blocks during the sampling process. It is impossible to effectively prevent the core blocks from breaking or being damaged, which affects the accuracy and reliability of subsequent laboratory tests. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a detection device for municipal road concrete strength and a control system thereof.

[0005] In a first aspect, the present invention provides a testing device for municipal road concrete strength, comprising a mobile frame, the mobile frame comprising a vertical rod, and further comprising:

[0006] A lifting frame is slidably mounted on the vertical rod and is driven to move by a vertical driving assembly, and a second supporting plate is fixed on the side wall of the lifting frame;

[0007] The sampling tube is rotatably mounted on the bottom of the second support plate via a rotating shaft and driven to rotate by a rotating drive assembly;

[0008] A separation component, installed inside the sampling tube, used to push the sample inside the sampling tube to separate;

[0009] A water cooling assembly, mounted on the top of the second support plate;

[0010] A sample storage component, installed on the mobile rack, and used to cooperate with the detachment component to store and protect the detached samples;

[0011] A control unit, used for controlling the detachment component to push the sample to detach after the sampling tube has finished sampling, and controlling the sample storage component to automatically store the detached sample;

[0012] After the mobile frame moves to the position where sampling is required, the control unit controls the vertical drive assembly and the rotation drive assembly to start. After the rotation drive assembly is started, it drives the sampling tube to rotate. After the vertical drive assembly is started, it drives the lifting frame to move downward along the vertical rod, thereby driving the sampling tube to move downward. The sampling tube moves downward in a high-speed rotating state. At the same time, the control unit controls the water cooling assembly to start. The water cooling assembly delivers cooling water to the sampling tube, so that the sampling tube is cooled by the cooling water of the water cooling assembly during the process of sampling the concrete pavement downward, which is conducive to the smooth sampling. After the sampling tube sampling is completed, the vertical drive assembly drives the lifting frame to move upward, thereby driving the sampling tube to move upward and reset. After the sampling tube is reset, the control unit controls the sample storage assembly The sample storage component is started to move to the bottom of the sampling tube, and then the control unit controls the detachment component to start, so that the detachment component pushes the sample to detach from the inside of the sampling tube after it is started, so that the sample falls into the inside of the sample storage component after detachment, thereby realizing automatic detachment and storage of the sample. During the whole process, the sample will not stay in the external environment for a long time, which is conducive to avoiding the interference of the external environment on the sample, and through the automated setting, the whole sampling process is convenient and fast, which is conducive to improving the efficiency of sample sampling, and the samples are stored separately, which is conducive to avoiding the sample from being damaged during the storage and placement process, thereby affecting the subsequent detection effect of the sample experiment, thereby helping to improve the accuracy of the municipal road concrete strength detection.

[0013] The disengagement assembly comprises:

[0014] A cylinder fixed to the top of the sampling tube;

[0015] A push plate is fixed to the end of the telescopic rod of the cylinder, and a plurality of air-permeable gaps are formed through the top of the push plate in a circular array;

[0016] After the cylinder is started, the pushing plate can be pushed downward by the telescopic rod. After the pushing plate moves downward, the sample inside the sampling tube can be pushed downward. The setting of the air permeable gap ensures that the sampling process will not be interfered with by the effect of air pressure, which is conducive to the smooth sampling of the sampling tube.

[0017] The sample storage component comprises:

[0018] A rotating drum rotatably mounted on the top of the bottom plate of the mobile frame;

[0019] A rotation driving assembly, installed at the bottom of the mobile frame, for driving the rotating cylinder to rotate;

[0020] A movable plate, fixed on the side wall of the rotating cylinder;

[0021] A storage shell is placed above the movable plate, and when the movable plate drives the storage shell to move below the sampling tube, the storage shell wraps and protects the sample;

[0022] An automatic replacement component, installed on the mobile rack, for automatically replacing the storage shell after storage is completed, so as to replace and store the storage shell enclosing the sample;

[0023] After the rotating drive component is started, it drives the rotating cylinder to rotate. When the rotating cylinder rotates to a position facing the automatic replacement component, the automatic replacement component can replace the storage shell on the movable plate, so that after the sample is stored inside the storage shell, the storage shell storing the sample is stored, and the new storage shell is replaced and placed on the movable plate. When the rotating drive component drives the rotating cylinder to rotate to a position facing the sampling tube, the rotating cylinder drives the storage shell to move to just below the sampling tube, so that after the detachment component drives the sample to detach from the sampling tube, the sample falls into the storage shell and is stored, which is conducive to automatic storage of the sample, thereby helping to avoid the situation where the sample after sampling is damaged during the transportation and storage process, thereby affecting the detection effect of the sample.

[0024] The automatic replacement component comprises:

[0025] A box body is slidably mounted on the bottom plate of the mobile rack, and the interior of the box body is used to store the empty storage shells;

[0026] A moving drive assembly, used for driving the box body to move a distance corresponding to the replacement of the storage shell each time;

[0027] A magnetic attraction component is installed between the rotating cylinder and the storage shell, and is used to push the storage shell to be replaced by magnetic attraction;

[0028] The mobile driving component can drive the box body to move a distance that a storage shell needs to be moved for replacement each time. After the storage shell has completed storing the sample, the rotating driving component drives the rotating cylinder to drive the movable plate to rotate to a position facing the box body, and then the magnetic attraction component is started. Through the magnetic repulsion of the magnetic attraction component, the storage shell on the movable plate is pushed to move toward the inside of the box body. Then the mobile driving component drives the box body to move a storage shell replacement distance, so that the position relative to the movable plate is replaced with a new storage shell. Then the magnetic attraction component starts to switch to the magnetic attraction state, and the new storage shell is pulled toward the movable plate by the magnetic attraction force until the storage shell moves to the movable plate to complete the replacement of the storage shell, thereby automatically realizing the replacement of the storage shell, and replacing the storage shell with a new empty storage shell after storing the storage shell, which is beneficial to the automatic storage replacement of the sample, thereby facilitating the improvement of the efficiency of sample storage.

[0029] Preferably, it also includes:

[0030] An inner shell, arranged one-to-one with the storage shells, and placed inside the corresponding storage shells;

[0031] A plurality of springs are respectively fixed on the outer walls of the inner shells in various directions, and one end of the spring facing away from the inner shell is fixedly connected to the inner wall of the storage shell;

[0032] Flexible rubber, fixed between the outer edge of the opening of the inner shell and the inner edge of the opening of the storage shell;

[0033] When the storage shell vibrates, since the sample is stored inside the inner shell, the storage shell drives the inner shell to vibrate, and the vibration of the inner shell is buffered by the spring, which helps to slow down the vibration of the inner shell, thereby helping to slow down the vibration effect during the sample transportation process, thereby helping to avoid the sample being damaged by the vibration and affecting the sample detection result, thereby helping to improve the accuracy of sample detection;

[0034] The provision of the flexible rubber can also mitigate the impact between the opening of the inner shell and the opening of the storage shell, and is helpful in preventing foreign matter from entering between the two, thereby interfering with the shock-absorbing effect of the spring.

[0035] On the other hand, a control system for a municipal road concrete strength detection device is provided, wherein the control unit includes a cloud for storing information and a user end for inputting information, and the control system is used for a control method of the municipal road concrete strength detection device, comprising the following steps:

[0036] A1. The control unit obtains status information from the vertical drive assembly, wherein the status information includes a sampling status and a reset status;

[0037] A2. When the state information is in a reset state, the control unit generates storage control information, and the storage control information is used to control the start of the rotation drive component;

[0038] A3. The control unit sends the storage control information to the rotation drive assembly;

[0039] The vertical drive component drives the lifting frame to drive the sampling tube to move to different positions and different states. When driving the sampling tube to move to the topmost position, the vertical drive component generates a reset state. When driving the sampling tube downward for sampling, the vertical drive component generates a sampling state. Both the sampling state and the reset state are state information. The vertical drive component sends the state information to the control unit. When the state information obtained by the control unit is the reset state, the control unit generates storage control information and sends the storage control information to the rotation drive component to control the rotation drive component to start driving the rotating drum to rotate for transporting the storage shell, so as to transport the storage shell to the bottom of the sampling tube for sample storage.

[0040] Preferably, different scanning codes are arranged on the outer walls of all the storage shells, a camera for identifying the scanning codes is installed on the mobile rack, a positioning component for identifying the position of the mobile rack and the current time is installed on the mobile rack, and further comprising:

[0041] When the state information is a sampling state, the control unit obtains position information from the positioning component;

[0042] When the state information is in a reset state, the control unit obtains scan code information from the camera;

[0043] The control unit generates marking information according to the position information and the scan code information, wherein the marking information is an information group formed by linking the position information and the scan code information;

[0044] The control unit uploads the information group to cloud storage to form an information table;

[0045] The positioning component detects the position of the mobile rack and the current time, and generates position information according to the detection result. When the state information acquired by the control unit is sampling information, the positioning component sends the position information to the control unit, so that the control unit acquires the position information;

[0046] The camera is aimed at the moving plate, and when the storage shell moves to above the moving plate, the scanning code on the storage shell falls into the field of view of the camera. When the state information obtained by the control unit is a sampling state, the storage shell moves to above the moving plate under control, and the camera scans the scanning code on the storage shell to generate scanning code information, and sends the scanning code information to the control unit, so that the control unit obtains the scanning code information from the camera;

[0047] The control unit generates marking information according to the position information and the scan code information, and the marking information is an information group formed by linking the position information and the scan code information, so that the position information and the scan code information appear as an information group, so that when the scan code information is obtained, the position information can be automatically popped up, and when the position information is identified, the corresponding scan code information can be automatically popped up, thereby facilitating the identification of the sample sampling position, and when the sampling position is reached, the sampling performed at the position can be identified, which is beneficial to the classification analysis and storage of the samples, thereby facilitating the improvement of the efficiency of sample detection.

[0048] Preferably, a distance sensor is installed at the bottom of the push plate, and the step A2 further includes:

[0049] The control unit acquires distance information D from the distance sensor;

[0050] The control unit acquires standard depth information L0 and stored depth information L1 from the user terminal;

[0051] The control unit substitutes the standard depth information L0, the stored depth information L1, and the distance information D into a judgment formula L1<L0-D, and if the judgment formula is met, the control unit generates abnormal information;

[0052] The control unit generates pause information according to the abnormal information and the storage control information, wherein the pause information is used to control the rotation drive component to pause starting when receiving the storage control information;

[0053] The control unit sends the pause information to the rotation drive assembly;

[0054] The distance sensor can detect the distance between itself and the top of the sample in the sampling tube, thereby generating distance information D, and sending the distance information D to the control unit, so that the control unit obtains the distance information D;

[0055] The operator can input the corresponding standard depth information L0 and storage depth information L1 through the user terminal. The standard depth information L0 is the distance between the distance sensor on the push plate and the bottom opening of the sampling tube when the distance sensor inside the sampling tube is at the highest position, that is, when the cylinder is in a contracted state. The value of the standard depth information L0 is different for sampling tubes of different sizes. The standard depth information L0 is a variable value, and the operator inputs different data information according to different sampling tubes used. The storage depth information L1 is the maximum depth that can be stored inside the storage shell. The value of the storage depth information L1 is different for different storage shell sizes. The storage depth information L1 is a variable value, and the operator inputs different data information according to different storage shells used.

[0056] The control unit substitutes the acquired standard depth information L0, storage depth information L1 and distance information D into the judgment formula L1<L0-D. If the judgment formula is met, that is, the maximum storage depth of the storage shell is less than the sample depth of the sample, the sample cannot be stored inside the storage shell at this time, and the control unit generates abnormal information. At this time, the control unit generates pause information after simultaneously acquiring the abnormal information and the storage control information, and sends the pause information to the rotation drive component, so that the rotation drive component that receives the pause information pauses when it receives the storage control information in this round, so that the rotation drive component pauses once to drive the rotating drum to rotate and drive the storage shell to move to the bottom of the sampling tube for sample storage, and instead makes the samples that cannot be stored detached and discarded under the action of the detachment component, thereby avoiding the storage of samples that cannot be stored and causing equipment failure.

[0057] Preferably, it also includes:

[0058] The control unit acquires angle information from the rotation drive assembly, wherein the angle information includes a reset replacement angle, a rotation angle, and a sample receiving angle;

[0059] When the angle information is a reset replacement angle, the control unit generates same magnetic pole control information, replacement control information, and different magnetic pole control information;

[0060] The control unit obtains time interval information from the user terminal;

[0061] The control unit sequentially sends the same magnetic pole control information, the replacement control information, and the different magnetic pole control information to the magnetic attraction component, the mobile drive component, and the magnetic attraction component according to the time interval information;

[0062] When the rotating drive assembly drives the rotating cylinder to rotate, the rotating angle is identified to generate different angle information. When the rotating cylinder drives the movable plate to rotate to face and align with the box body, the rotating drive assembly generates a reset replacement angle. When the rotating cylinder drives the movable plate to rotate to face and align with the sampling tube, the rotating drive assembly generates a sample receiving angle. At other angles, the rotating drive assembly generates a rotation angle. The rotating drive assembly sends the angle information to the control unit so that the control unit obtains the angle information.

[0063] When the angle information is a reset replacement angle, the control unit generates same-pole control information, replacement control information, and different-pole control information, and the control unit obtains time interval information from the user end. The time interval information is the time interval for sending the same-pole control information, replacement control information, and different-pole control information to the magnetic suction component and the mobile drive component, respectively. The operator inputs it according to the operation needs, so that after the magnetic suction component pushes the storage shell into the interior of the box body, the control unit sends the replacement control information to the mobile drive component to control the mobile drive component to drive the box body to move and replace. After the box body is moved and replaced, the control unit sends the different-pole control information to the magnetic suction component to pull the new storage shell to the top of the mobile plate to complete the replacement of the storage shell.

[0064] Preferably, after step A3, the following steps are further included:

[0065] When the angle information is a sample receiving angle, the control unit generates push control information, and the push control information is used to control the start of the separation component;

[0066] The control unit sends the push control information to the disengagement component;

[0067] When the angle information obtained by the control unit is the sample receiving angle, the control unit generates push control information and sends the push control information to the detachment component to control the detachment component to start pushing the sample inside the sampling tube to detach from the sampling tube, thereby realizing automatic detachment and storage of the sample.

[0068] Compared with the prior art, the present invention has the following beneficial effects:

[0069] 1. The present invention makes the entire sampling process convenient and quick by setting up the sample storage component and the separation component, which is beneficial to improving the efficiency of sample sampling, and stores the samples separately, which is beneficial to avoid the samples being damaged during the storage process, thereby affecting the subsequent detection effect of the sample experiment, which is beneficial to improving the accuracy of the municipal road concrete strength detection.

[0070] 2. The present invention sets a control unit so that the position information and the scan code information appear as an information group, so that when the scan code information is obtained, the position information can be automatically popped up, and when the position information is identified, the corresponding scan code information can be automatically popped up, thereby facilitating the identification of the sample sampling position, and when the sampling position is reached, the sampling performed at the position can be identified, which is beneficial to the classification analysis and storage of the samples, thereby helping to improve the efficiency of sample detection.

DETAILED DESCRIPTION

[0083] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0084] like Figures 2 to 11 The present invention shows a testing device for the strength of municipal road concrete, comprising a mobile frame 1, wherein the mobile frame 1 comprises a vertical rod 101 and further comprises:

[0085] The lifting frame 2 is slidably mounted on the vertical rod 101 and is driven to move by the vertical driving assembly. A second support plate 4 is fixed on the side wall of the lifting frame 2;

[0086] The sampling tube 5 is rotatably mounted on the bottom of the second support plate 4 via a rotating shaft 501 and is driven to rotate by a rotating drive assembly;

[0087] A separation component is installed inside the sampling tube 5 and is used to push the sample inside the sampling tube 5 to separate;

[0088] A water cooling assembly is installed on the top of the second support plate 4;

[0089] The sample storage component is installed on the mobile rack 1 and is used to cooperate with the detachment component to store and protect the detached samples;

[0090] The control unit is used to control the detachment component to push the sample to detach after the sampling tube 5 has finished sampling, and control the sample storage component to automatically store the detached sample;

[0091] The existing coring machine adopts a semi-automatic method. After drilling and sampling, the staff needs to manually remove the sample core block from the inside of the drill bit or the inside of the borehole. The operation is relatively troublesome, and there is insufficient protection for the sample core block during the sampling process. It cannot effectively prevent the core block from breaking or being damaged, which affects the accuracy and reliability of subsequent laboratory tests.

[0092] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: after the mobile frame 1 moves to the position where sampling is required, the control unit controls the vertical drive component and the rotation drive component to start. After the rotation drive component is started, it drives the sampling tube 5 to rotate. After the vertical drive component is started, it drives the lifting frame 2 to move downward along the vertical rod 101, thereby driving the sampling tube 5 to move downward. The sampling tube 5 moves downward in a high-speed rotating state. At the same time, the control unit controls the water cooling component to start, and the water cooling component conveys cooling water to the sampling tube 5, so that the sampling tube 5 is cooled by the cooling water of the water cooling component during the process of sampling the concrete pavement downward, thereby facilitating the smooth sampling. After the sampling tube 5 completes the sampling, the vertical drive component drives the lifting frame 2 to move upward, thereby driving the sampling tube 5 to move upward and reset. After the sample tube 5 is reset, the control unit controls the sample storage component to start, so that the sample storage component moves to the bottom of the sampling tube 5, and then the control unit controls the detachment component to start, so that after the detachment component is started, it pushes the sample to detach from the inside of the sampling tube 5, so that the sample falls into the inside of the sample storage component after detachment, thereby realizing automatic detachment and storage of the sample. During the whole process, the sample will not stay in the external environment for a long time, which is conducive to avoiding interference of the external environment on the sample, and through the automated setting, the whole sampling process is convenient and fast, which is conducive to improving the efficiency of sample sampling, and the samples are stored separately, which is conducive to avoiding damage to the sample during storage and placement, thereby affecting the subsequent detection effect of the sample experiment, thereby helping to improve the accuracy of municipal road concrete strength detection.

After the second synchronous wheel 504 rotates, it drives the first synchronous belt 503 to transmit. The first synchronous belt 503 drives the first synchronous wheel 502 to rotate. The first synchronous wheel 502 drives the rotating shaft 501 to rotate. The rotating shaft 501 drives the sampling tube 5 to rotate, thereby realizing the rotation drive of the sampling tube 5.

[0103] It should be noted that an oil generator is installed on the first support plate 3 to provide power for the drive motor 505 , which is a mature existing technology and will not be described in detail here.

After the pushing plate 601 moves downward, it can push the sample inside the sampling tube 5 to move downward. The setting of the air permeable gap 602 ensures that the sampling process will not be interfered with by the effect of air pressure, which is conducive to the smooth sampling of the sampling tube 5.

[0116] The movable plate 801 is fixed on the side wall of the rotating cylinder 8;

[0117] The storage shell 9 is placed above the moving plate 801. When the moving plate 801 drives the storage shell 9 to move below the sampling tube 5, the storage shell 9 wraps and protects the sample.

[0118] An automatic replacement component is installed on the mobile rack 1 and is used to automatically replace the storage shell 9 after storage is completed, so as to replace and store the storage shell 9 wrapping the sample;

[0119] After the rotating drive component is started, it drives the rotating cylinder 8 to rotate. When the rotating cylinder 8 rotates to a position facing the automatic replacement component, the automatic replacement component can replace the storage shell 9 on the movable plate 801, so that after the sample is stored inside the storage shell 9, the storage shell 9 storing the sample is stored, and a new storage shell 9 is replaced and placed on the movable plate 801. When the rotating drive component drives the rotating cylinder 8 to rotate to a position facing the sampling tube 5, the rotating cylinder 8 drives the storage shell 9 to move to directly below the sampling tube 5, so that after the detachment component drives the sample to detach from the sampling tube 5, the sample falls into the storage shell 9 and is stored, which is conducive to automatic storage of the sample, thereby helping to avoid the sample after sampling being damaged during the transportation and storage process, thereby affecting the detection effect of the sample.

After the fourth synchronous wheel 804 rotates, it drives the second synchronous belt 803 to transmit. The second synchronous belt 803 drives the third synchronous wheel 802 to rotate. After the third synchronous wheel 802 rotates, it drives the rotating cylinder 8 to rotate, thereby realizing the sample transportation by driving the rotating cylinder 8 to rotate.

[0125] As an optional embodiment, the automatic replacement component includes:

[0126] A box body 10 is slidably mounted on the bottom plate of the mobile rack 1, and the interior of the box body 10 is used to store empty storage shells 9;

[0127] A moving driving assembly, used for driving the box body 10 to move a distance corresponding to the replacement of a storage shell 9 each time;

[0128] A magnetic attraction component is installed between the rotating cylinder 8 and the storage shell 9, and is used to push the storage shell 9 to be replaced by magnetic attraction;

[0129] The mobile driving component can drive the box body 10 to move a distance each time that a storage shell 9 needs to be moved to replace. After the storage shell 9 has completed storing the sample, the rotating driving component drives the rotating cylinder 8 to drive the movable plate 801 to rotate to a position facing the box body 10, and then the magnetic attraction component is started. Through the magnetic repulsion of the magnetic attraction component, the storage shell 9 on the movable plate 801 is pushed to move toward the inside of the box body 10, and then the mobile driving component drives the box body 10 to move a storage shell 9 replacement distance, so that the position relative to the movable plate 801 is replaced with a new storage shell 9, and then the magnetic attraction component is started to switch to the magnetic attraction state, and the new storage shell 9 is pulled to move onto the movable plate 801 by the magnetic attraction force until the storage shell 9 moves to the movable plate 801 to complete the replacement of the storage shell 9, thereby automatically realizing the replacement of the storage shell 9, so as to replace the new empty storage shell 9 after storing the storage shell 9 storing the sample, which is conducive to the automatic storage and replacement of the sample, thereby helping to improve the efficiency of sample storage.

[0130] As an optional embodiment, the mobile driving component includes:

[0131] The third motor 1004 is fixed to the bottom plate of the mobile frame 1 through a bracket;

[0132] Gear 1003, fixed on the output shaft of the third motor 1004;

[0133] The rack 1002 is fixed on the side wall of the box body 10, and the rack 1002 is meshed with the gear 1003;

[0134] After the third motor 1004 is started, the output shaft drives the gear 1003 to rotate. After the gear 1003 rotates, it drives the rack 1002 meshing with it to move, thereby driving the box body 10 to move through the rack 1002, thereby realizing the movement drive of the box body 10.

[0135] As an optional embodiment, the magnetic attraction component includes:

[0136] The electromagnet 11 is fixed on the side wall of the rotating cylinder 8;

[0137] A fixed magnet 12 is fixedly embedded on the side wall of the storage shell 9, and the fixed magnet 12 is adapted to the electromagnet 11;

[0138] A plurality of first rollers 806 are rotatably mounted on the top of the moving plate 801;

[0139] A plurality of groups of second rollers 1001, each group of second rollers 1001 is adapted to a storage shell 9, and each group of second rollers 1001 is rotatably installed at the bottom of the inner wall of the box body 10 in a linear array;

[0140] A limiting groove is provided at the bottom of each storage shell 9, and the limiting groove is adapted to both the first roller 806 and the second roller 1001;

[0141] When the electromagnet 11 is energized and adjusted to face the opposite magnetic poles of the fixed magnet 12 on the side wall of the storage shell 9, a magnetic attraction force is generated on the fixed magnet 12, thereby pulling the fixed magnet 12 to move to a position close to the electromagnet 11. The limiting groove provided at the bottom of the storage shell 9 is adapted to both the first roller 806 and the second roller 1001. When the storage shell 9 is inside the box body 10, the storage shell 9 moves along the track of the second roller 1001 under the action of the limiting groove. The setting of the second roller 1001 enables rolling contact between the second roller 1001 and the limiting groove, thereby facilitating the reduction of friction during the movement of the storage shell 9, thereby facilitating the movement of the storage shell 9 under the action of the magnetic force of the electromagnet 11. When the storage shell 9 moves to the top of the movable plate 801, similarly, the movement track of the storage shell 9 is limited under the action of the first roller 806, thereby facilitating the avoidance of the movement deviation of the storage shell 9, thereby facilitating the replacement of the storage shell 9.

[0142] It should be noted that a limiting plate is provided on the bottom plate of the movable rack 1, so that the storage shell 9 inside the box body 10 can move under the action of magnetic force only when it is aligned with the movable plate 801. When it is not aligned, it cannot move due to the limiting effect of the limiting plate, which helps to avoid the adjacent storage shells 9 being disturbed by the magnetic attraction and causing displacement.

[0143] As an optional embodiment, it also includes:

[0144] The inner shell 901 is arranged in one-to-one correspondence with the storage shell 9 and is placed inside the corresponding storage shell 9;

[0145] A plurality of springs 902 are fixed to the outer walls of each inner shell 901 in each direction, and one end of the spring 902 facing away from the inner shell 901 is fixedly connected to the inner wall of the storage shell 9;

[0146] The flexible rubber 903 is fixed between the outer edge of the opening of the inner shell 901 and the inner edge of the opening of the storage shell 9;

[0147] When the storage shell 9 vibrates, since the sample is stored inside the inner shell 901, the storage shell 9 drives the inner shell 901 to vibrate, and the vibration of the inner shell 901 is buffered by the spring 902, which helps to slow down the vibration of the inner shell 901, thereby helping to slow down the vibration effect during the sample transportation process, thereby helping to avoid the situation where the sample is damaged by the vibration and affects the sample detection result, thereby helping to improve the accuracy of the sample detection;

[0148] The provision of the flexible rubber 903 can also mitigate the impact between the opening of the inner shell 901 and the opening of the storage shell 9, and is helpful in preventing foreign matter from entering between the two, thereby interfering with the shock-absorbing effect of the spring 902.

[0149] like Figure 1 A control system for a municipal road concrete strength detection device is shown, the control unit includes a cloud for storing information and a user end for inputting information, and the control method for the municipal road concrete strength detection device of the control system includes the following steps:

[0150] A1. The control unit obtains status information from the vertical drive assembly, the status information including sampling status and reset status;

[0151] A2. When the status information is in the reset state, the control unit generates storage control information, and the storage control information is used to control the start of the rotation drive component;

[0152] A3. The control unit sends the storage control information to the rotation drive assembly;

[0153] The vertical drive component drives the lifting frame 2 to drive the sampling tube 5 to move to different positions and different states. When driving the sampling tube 5 to move to the topmost position, the vertical drive component generates a reset state. When driving the sampling tube 5 downward for sampling, the vertical drive component generates a sampling state. The sampling state and the reset state are both state information. The vertical drive component sends the state information to the control unit. When the state information obtained by the control unit is the reset state, the control unit generates storage control information and sends the storage control information to the rotation drive component to control the rotation drive component to start driving the rotating cylinder 8 to rotate for transporting the storage shell 9, so as to transport the storage shell 9 to the bottom of the sampling tube 5 for sample storage.

[0154] As an optional embodiment, different scanning codes are arranged on the outer walls of all storage shells 9, a camera for identifying the scanning code is installed on the mobile rack 1, and a positioning component for identifying the position of the mobile rack 1 and the current time is installed on the mobile rack 1, and further includes:

[0155] When the state information is a sampling state, the control unit obtains the position information from the positioning component;

[0156] When the status information is in a reset state, the control unit obtains scan code information from the camera;

[0157] The control unit generates marking information according to the position information and the scan code information, wherein the marking information is an information group formed by linking the position information and the scan code information;

[0158] The control unit uploads the information group to cloud storage to form an information table;

[0159] The positioning component detects the position of the mobile frame 1 and the current time, and generates position information according to the detection result. When the state information obtained by the control unit is a sampling state, the positioning component sends the position information to the control unit, so that the control unit obtains the position information;

[0160] The camera is aimed at the movable plate 801. When the storage shell 9 moves to above the movable plate 801, the scan code on the storage shell 9 falls into the field of view of the camera. When the state information obtained by the control unit is the reset state, the storage shell 9 moves to above the movable plate 801 under the control, and the camera scans the scan code on the storage shell 9 to generate scan code information, and sends the scan code information to the control unit, so that the control unit obtains the scan code information from the camera;

[0161] The control unit generates marking information according to the position information and the scan code information. The marking information is an information group formed by linking the position information and the scan code information, so that the position information and the scan code information appear as an information group, so that when the scan code information is obtained, the position information can be automatically popped up, and when the position information is identified, the corresponding scan code information can be automatically popped up, thereby facilitating the identification of the sample sampling position, and when the sampling position is reached, the sampling performed at the position can be identified, which is beneficial to the classification analysis and storage of the samples, thereby facilitating the improvement of the efficiency of sample detection.

[0162] As an optional embodiment, a distance sensor is installed at the bottom of the push plate 601, and after step A2, the following steps are further included:

[0163] The control unit obtains distance information D from the distance sensor;

[0164] The control unit obtains the standard depth information L0 and the stored depth information L1 from the user end;

[0165] The control unit substitutes the standard depth information L0, the stored depth information L1, and the distance information D into the judgment formula L1<L0-D. If the judgment formula is met, the control unit generates abnormal information;

[0166] The control unit generates pause information according to the abnormal information and the storage control information, and the pause information is used to control the rotation drive component to pause starting when receiving the storage control information;

[0167] The control unit sends a pause message to the rotation drive assembly;

[0168] The distance sensor can detect the distance between itself and the top of the sample in the sampling tube 5, thereby generating distance information D, and sending the distance information D to the control unit, so that the control unit obtains the distance information D;

[0169] The operator can input the corresponding standard depth information L0 and storage depth information L1 through the user terminal. The standard depth information L0 is the distance between the distance sensor on the push plate 601 and the bottom opening of the sampling tube 5 when the distance sensor inside the sampling tube 5 is at the highest position, that is, the cylinder 6 is in a contracted state. The value of the standard depth information L0 is different according to the different sizes of the sampling tube 5. The standard depth information L0 is a variable value. The operator inputs different data information according to the different sampling tubes 5 used. The storage depth information L1 is the maximum depth that can be stored inside the storage shell 9. The value of the storage depth information L1 is different according to the different sizes of the storage shell 9. The storage depth information L1 is a variable value. The operator inputs different data information according to the different storage shells 9 used.

[0170] The control unit substitutes the acquired standard depth information L0, storage depth information L1 and distance information D into the judgment formula L1<L0-D. If the judgment formula is met, that is, the maximum storage depth of the storage shell 9 is less than the sample depth of the sample, then the sample cannot be stored inside the storage shell 9, and the control unit generates abnormal information. At this time, the control unit generates pause information after simultaneously acquiring the abnormal information and the storage control information, and sends the pause information to the rotation drive component, so that the rotation drive component that receives the pause information pauses when it receives the storage control information in this round, so that the rotation drive component pauses once to drive the rotating cylinder 8 to rotate and drive the storage shell 9 to move to the bottom of the sampling tube 5 for sample storage, and the samples that cannot be stored are detached and discarded under the action of the detachment component, thereby avoiding the storage of samples that cannot be stored and causing equipment failure.

[0171] As an optional embodiment, it also includes:

[0172] The control unit obtains angle information from the rotation drive assembly, the angle information including a reset replacement angle, a rotation angle, and a sample receiving angle;

[0173] When the angle information is a reset replacement angle, the control unit generates same magnetic pole control information, replacement control information, and different magnetic pole control information;

[0174] The control unit obtains the time interval information from the user end;

[0175] The control unit sends the same magnetic pole control information, the replacement control information, and the different magnetic pole control information to the magnetic attraction component, the mobile drive component, and the magnetic attraction component in sequence according to the time interval information;

[0176] When the rotating drive assembly drives the rotating cylinder 8 to rotate, the rotating angle is identified to generate different angle information. When the rotating cylinder 8 drives the moving plate 801 to rotate toward and align with the box body 10, the rotating drive assembly generates a reset replacement angle. When the rotating cylinder 8 drives the moving plate 801 to rotate toward and align with the sampling tube 5, the rotating drive assembly generates a sample receiving angle. At other angles, the rotating drive assembly generates a rotation angle, and the rotating drive assembly sends the angle information to the control unit, so that the control unit obtains the angle information.

[0177] When the angle information is a reset replacement angle, the control unit generates same-pole control information, replacement control information, and different-pole control information, and the control unit obtains time interval information from the user end. The time interval information is the time interval for sending the same-pole control information, replacement control information, and different-pole control information to the magnetic attraction component, the mobile drive component, and the magnetic attraction component respectively. The operator inputs it according to the operation needs, so that after the magnetic attraction component pushes the storage shell 9 into the interior of the box body 10, the control unit sends the replacement control information to the mobile drive component to control the mobile drive component to drive the box body 10 to move and replace. After the box body 10 is moved and replaced, the control unit sends the different-pole control information to the magnetic attraction component to pull the new storage shell 9 to the top of the movable plate 801 to complete the replacement of the storage shell 9.

[0178] As an optional embodiment, step A3 further includes:

[0179] When the angle information is a receiving sample angle, the control unit generates push control information, and the push control information is used to control the start of the separation component;

[0180] The control unit sends a push control message to the disengagement component;

[0181] When the angle information obtained by the control unit is the sample receiving angle, the control unit generates push control information and sends the push control information to the detachment component to control the detachment component to start pushing the sample inside the sampling tube 5 to detach from the sampling tube 5, thereby realizing automatic detachment and storage of the sample.

[0182] The working principle of the present invention is as follows: after the mobile frame 1 moves to the position where sampling is required, the control unit controls the vertical driving component and the rotating driving component to start, and after the rotating driving component is started, it drives the sampling tube 5 to rotate, and after the vertical driving component is started, it drives the lifting frame 2 to move downward along the vertical rod 101, thereby driving the sampling tube 5 to move downward, and the sampling tube 5 moves downward in a high-speed rotating state. At the same time, the control unit controls the water cooling component to start, and the water cooling component conveys cooling water to the sampling tube 5, so that the sampling tube 5 is cooled by the cooling water of the water cooling component during the process of sampling the concrete pavement downward, thereby facilitating the smooth sampling. After the sampling tube 5 completes the sampling, the vertical driving component drives the lifting frame 2 to move upward, thereby driving the sampling tube 5 to move upward and reset. After the sampling tube 5 is reset, the control unit controls the lifting frame 2 to move upward, thereby driving the sampling tube 5 to move upward and reset. The unit controls the start-up of the sample storage component, so that the sample storage component moves to the bottom of the sampling tube 5, and then the control unit controls the start-up of the detachment component, so that after the detachment component is started, it pushes the sample to detach from the inside of the sampling tube 5, so that the sample falls into the inside of the sample storage component after detachment, thereby realizing automatic detachment and storage of the sample. During the whole process, the sample will not stay in the external environment for a long time, which is conducive to avoiding interference of the external environment on the sample, and through the automated setting, the whole sampling process is convenient and fast, which is conducive to improving the efficiency of sample sampling, and the samples are stored separately, which is conducive to avoiding damage to the sample during storage and placement, thereby affecting the subsequent detection effect of the sample experiment, thereby helping to improve the accuracy of municipal road concrete strength detection.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
