Description

Technical Field

[0001] The invention relates to the technical field related to concrete, and in particular to a portable concrete core sample leveling machine. Background Art

[0002] The core drilling method belongs to the destructive method to test the compressive strength of concrete. It mainly involves drilling core samples from concrete structures or components. The core samples are then tested for compressive strength on a laboratory press. Before the experiment, the core samples must be processed to ensure that the ends of the core samples are flat. Otherwise, uneven force will have a significant impact on the test results.

[0003] In the existing core sample leveling process, such as the Chinese patent with announcement number CN220170677U, a concrete core sample leveling instrument is disclosed, including a base, a clamping screw is rotatably connected to the base, both ends of the clamping screw are threadedly connected to the first and second clamping nuts, the first clamping nut is connected to the first clamping block, the second clamping nut is connected to the second clamping block, the first and second clamping blocks are provided with clamping block slide rails, and the clamping block slide rails are slidably connected to the base slide rails; the rear part of the base is fixedly connected to the lifting column seat, the lifting column seat is connected to the lifting column, the lifting column is rotatably connected to the lifting screw through the lifting screw bearing, the lifting screw is threadedly connected to the lifting nut, a lifting nut ear is provided on the lifting nut, the lifting nut ear is connected to the sliding sleeve, the sliding sleeve is slidably connected to the lifting column up and down, and a clamping device is provided at the end of the sliding sleeve.

[0004] In the above-mentioned prior art, concrete core samples of different sizes are clamped mainly by the first and second clamping blocks to expand the application scope of the concrete core sample leveling instrument. However, the above-mentioned prior art does not take into account that when leveling the core sample, the thickness of the leveling layer should not be too thick (the Technical Specification for Testing Concrete Strength by Core Drilling Method of the People's Republic of China (JGJ / T384-2016) stipulates that the thickness of the leveling layer should not be greater than 2mm), otherwise it will also affect the test results. However, the naked eye cannot observe the flatness of the end face of the core sample very well, so it may cause the thickness of the leveling layer after leveling to exceed the prescribed standard, resulting in errors in the test results. Moreover, for some cases where the height difference of the end face of the core sample is small, grinding is more convenient and quicker than leveling with slurry.

[0005] Based on this, there is still room for improvement in the above-mentioned prior art. Summary of the invention

[0029] The following is combined with Figure 1-Figure 9 This application is described in further detail.

[0030] The embodiment of the present application discloses a portable concrete core sample leveling machine, which clamps the concrete core sample in mid-air and detects the flatness of the two end faces of the core sample. Different processing methods are adopted according to whether the height difference of the end faces meets the standards, so as to ensure that the end faces of the core sample are flat after processing and the thickness of the core sample leveling layer is within the standard range.

[0032] In the actual leveling process, the concrete core sample is clamped on the clamping module 3, the mounting shell 5 is controlled to close to the core sample, and the detection module 6 gradually contacts and triggers the end face of the core sample. After being triggered, the detection module 6 detects the flatness of the end face of the core sample. At this time, there are two situations. If the end face of the core sample is flat, no operation is performed. If the end face of the core sample is uneven, there are two situations here. One is that the height difference of the end face of the core sample meets the standard, then the grinding module 7 is triggered, and the end face of the core sample is polished flat. The other is that the height difference of the end face of the core sample does not meet the standard, and the grinding module 7 is also triggered, but At this time, the grinding module 7 grinds the end face of the core sample to a certain degree and then stops working. After that, the linkage module 9 triggers the material preparation module 8 to stir the repair slurry to prevent condensation, and then the leveling module 10 performs a leveling operation on the end face of the core sample. The present application performs flatness detection on both ends of the concrete core sample by means of a suspended clamping method, and performs compliance treatment on the end faces that do not meet the standards. The detection is more comprehensive and the height difference of the end faces of the core samples can be intelligently distinguished. According to different situations, targeted treatment methods are adopted to level the end faces of the core samples, and the treatment methods are more flexible.

The electric driving component 61 is installed on the inner wall of the mounting shell 5, and an electric turntable is installed on the output end of the electric driving component 61. The rotating column 62 is installed on the electric turntable. The mounting plate 63 is installed at the end of the rotating column 62. The mounting plate 63 is close to the clamping module 3 and is provided with a reference plate 64 on the side thereof that slides up and down. A spring 1 is connected between the reference plate 64 and the mounting plate 63, and the springs work together to reset. The detection head 1 65 is slidably arranged at the center of the mounting plate 63. A spring 2 is connected between the detection head 1 65 and the mounting plate 63. The spring 2 always pushes the detection head 1 65 toward the clamping module 3. The detection head 2 66 is slidably arranged on the mounting plate 63. A spring 3 is connected between the detection head 2 66 and the mounting plate 63. The spring 3 always pushes the detection head 2 66 toward the clamping module 3. The structure of the detection head 2 66 is exactly the same as that of the detection head 1 65. The lock The fixing mechanism 67 locks the positions of the detection head 1 65 and the detection head 2 66, and the trigger mechanism 68 triggers different subsequent actions according to the detection results of the detection head 1 65 and the detection head 2 66. During operation, the mounting shell 5 descends, the reference plate 64 contacts the highest point of the core sample end face and stops, the mounting shell 5 continues to descend, the mounting plate 63 moves downward relative to the mounting shell 5, the spring 1 is compressed, the locking mechanism 67 is unlocked, and the detection head 1 65 and the detection head 2 66 have a tendency to move toward the end face of the core sample under the action of the spring 2 and the spring 3 respectively. The detection head 1 65 is in contact with the center position of the core sample end face. The detection head 66 detects the outer circle position of the core sample end face. If the core sample end face is flat, the detection head 65 and the detection head 66 remain stationary. If the core sample end face is uneven but the height difference is within the standard range, the detection head 65 and the detection head 66 descend until they rest on the core sample end face (this descending distance is relatively small), and the polishing module 7 is triggered. If the core sample end face is uneven and the height difference is outside the standard range, the detection head 65 and the detection head 66 descend until they rest on the core sample end face (this descending distance is relatively small), the polishing module 7 is triggered, and the linkage module 9 is also triggered.

[0034] Reference Figure 7As shown, the locking mechanism 67 includes a locking plug plate 671 and an unlocking block 672. The locking plug plate 671 is slidably arranged inside the mounting plate 63, and a spring four is connected between the locking plug plate 671 and the mounting plate 63. The spring four always keeps the locking plug plate 671 moving away from the detection head 65. The outer periphery of the detection head 65 is provided with a locking groove corresponding to the position of the locking plug plate 671. The unlocking block 672 is slidably arranged in the mounting plate 63 up and down, and a spring five is connected between the unlocking block 672 and the mounting plate 63. The spring five plays a resetting role. The left and right sides of the unlocking block 672 of the T-shaped structure are provided with chamfered structures that are squeezed and matched with the locking plug plate 671. The lower end of the unlocking block 672 is aligned with the reference The plates 64 are in contact and extrusion fit. The unlocking block 672 in the initial state has an extrusion and limiting effect on the locking plug plate 671. The locking plug plate 671 is squeezed and inserted into the locking groove to lock the position of the detection head 65. When relative sliding occurs between the mounting plate 63 and the reference plate 64, the reference plate 64 and the unlocking block 672 are in contact and squeezed, and the unlocking block 672 is squeezed and moved upward. The unlocking block 672 moving upward no longer limits the locking plug plate 671. Under the action of spring four, the locking plug plate 671 disengages from the locking groove. When the reference plate 64 is reset, the unlocking block 672 is reset under the action of spring five, and the reset unlocking block 672 squeezes the locking plug plate 671 back into the locking groove.

[0035] During the actual detection process, the mounting shell 5 descends, the reference plate 64 contacts and stops at the highest point of the core sample end face, the mounting shell 5 continues to descend, the mounting plate 63 moves downward relative to the mounting shell 5, the spring 1 is compressed, the reference plate 64 contacts and squeezes the unlocking block 672, the unlocking block 672 is squeezed and moves upward, and the unlocking block 672 moving upward no longer limits the locking plug plate 671. Under the action of the spring 4, the locking plug plate 671 is disengaged from the locking groove, and the detection head 1 65 and the detection head 2 66 have a tendency to move toward the end face of the core sample under the action of the spring 2 and the spring 3 respectively. If the end surface of the core sample is flat, the detection head 1 65 and the detection head 2 66 remain stationary. If the end surface of the core sample is uneven but the height difference is within the standard range, the detection head 1 65 and the detection head 2 66 descend until they touch the end surface of the core sample (this descending distance is relatively small), and the polishing module 7 is triggered. If the end surface of the core sample is uneven and the height difference is outside the standard range, the detection head 1 65 and the detection head 2 66 descend until they touch the end surface of the core sample (this descending distance is relatively small), the polishing module 7 is triggered, the linkage module 9 is also triggered, and the electric turntable drives the rotating column 62 to rotate at a low speed, thereby detecting the entire end surface of the core sample.

[0036] Reference Figure 7As shown, different processing methods need to be adopted according to the different ranges of the height difference of the core sample end face. For this reason, the present application is provided with a trigger mechanism 68 to trigger different processing methods. The trigger mechanism 68 includes a trigger plate 681, a trigger button 682, and an over-trigger 683. The trigger plate 681 is respectively mounted on the detection head 1 65 and the detection head 2 66. The trigger button 682 is mounted on the mounting plate 63 through the bracket 1. The positions of the trigger button 682 and the trigger plate 681 correspond. The trigger button 682 is a micro switch of the prior art. The trigger button 682 is electrically connected to the electric motor 75 and the power supply of the electric motor 75. The trigger plate 681 is in contact with the trigger button 682 in the initial state. The trigger button 682 is at In the closed state, when the trigger plate 681 is disengaged from the trigger button 682, the trigger button 682 triggers the electric motor 75 to work (it is in parallel cooperation, as long as one of the trigger buttons 682 is triggered, the electric motor 75 will start), and the excessive trigger member 683 is set on the bracket two for sliding up and down, and the bracket two is installed on the mounting plate 63. The positions of the excessive trigger member 683 and the trigger plate 681 correspond to each other, and there is no contact between the excessive trigger member 683 and the trigger plate 681 in the initial state. When the height difference of the end face of the core sample exceeds the standard, the detection head two 66 moves a large distance, and the trigger plate 681 follows the detection head two 66 to move a large distance. The moving trigger plate 681 squeezes the excessive trigger member 683 to trigger the linkage module 9.

[0037] During the actual triggering process, the uneven end surface of the core sample causes the detection head 1 65 and the detection head 2 66 to move. The movement of the detection head 1 65 and the detection head 2 66 causes the trigger plate 681 to separate from the trigger button 682. The trigger button 682 triggers the electric motor 75 to work. At this time, the excessive trigger member 683 is not in contact with the trigger plate 681. When the height difference of the core sample end surface exceeds the standard, the trigger plate 681 moves a larger distance and contacts with the excessive trigger member 683, thereby triggering the linkage module 9.

[0039] Reference Figure 4-Figure 6As shown, the knife-discharging mechanism includes a pier block 73, a moving frame 74, an electric motor 75, a lifting member 76, a pushing member 77, a pier groove 631, a lifting groove 731, and an inclined groove 711. The pier block 73 is installed on the reference plate 64. The mounting plate 63 is provided with a pier groove 631 corresponding to the pier block 73. The moving frame 74 is slidably arranged in the mounting plate 63 forward and backward. The moving frame 74 is a U-shaped structure. The position of the moving frame 74 corresponds to the pier block 73. When the mounting plate 63 descends relative to the reference plate 64, the pier block 73 3 is inserted into the pier dead groove 631 and abuts against the moving frame 74, so that the distance between the mounting plate 63 and the reference plate 64 is kept at a fixed value. The electric motor 75 is installed inside the mounting plate 63. The output end of the electric motor 75 is connected with a rotating screw. The rotating screw is rotatably arranged in the mounting plate 63. The moving frame 74 is threadedly matched with the rotating screw through the auxiliary block. When the trigger button 682 is triggered, the electric motor 75 is started, and the electric motor 75 drives the rotating screw to rotate. Under the action of the thread, the moving frame 74 moves The lifting member 76 is installed on the moving frame 74, the rear section of the lifting member 76 is a straight structure, the front section of the lifting member 76 is provided with an angled structure, the pier block 73 is provided with a lifting groove 731 corresponding to the position of the lifting member 76, the ejection member 77 is installed on the rear end of the moving frame 74, and the grinding knife 71 is provided with an inclined groove 711 corresponding to the position of the ejection member 77. When the moving frame 74 moves, the moving frame 74 gradually separates from the pier block 73, and the lifting member 76 is gradually inserted into the lifting groove 731 (at this time, the rear section of the lifting member 76 is flat). The straight section is inserted into the lifting groove 731, and no extrusion occurs between the lifting member 76 and the lifting groove 731). When the movable frame 74 is separated from the pier block 73, the pier block 73 is no longer limited. The angled structure of the front section of the lifting member 76 squeezes the lifting groove 731 to make the pier block 73 move upward, that is, the reference plate 64 moves upward. At the same time, during the movement of the movable frame 74, the ejector 77 moves with the movable frame 74. The ejector 77 squeezes the inclined groove 711 to make the grinding knife 71 extend downward, and the grinding knife 71 is in the working position.

[0041] Reference Figure 4 As shown, slurry is needed to level the end face of the core sample. In order to prevent the slurry from solidifying, the present application is provided with a material preparation module 8, which includes a storage shell 81 and an agitator 82. The storage shell 81 is installed on the periphery of the installation shell 5. The slurry used for repair is placed in the storage shell 81. The agitator 82 is rotatably arranged inside the storage shell 81. The agitator 82 is equipped with a propeller blade. The agitator 82 rotates to stir the slurry to make it more uniform and prevent it from solidifying.

[0042] Reference Figure 4 , Figure 7 , Figure 8As shown, the linkage module 9 includes a first gear 91, a connecting ring 911, a snap-on pin 92, a second gear 93, a pulley assembly 94, and a snap-on groove 621. The first gear 91 is rotatably arranged on the connecting ring 911, and the connecting ring 911 is slidably arranged on the inner wall of the mounting shell 5 up and down. A spring seven is connected between the connecting ring 911 and the mounting shell 5, and the spring seven plays a reset role. The first gear 91 is a circular ring structure with a through middle portion. The first gear 91 is sleeved on the outer periphery of the rotating column 62. The connecting ring 911 and the excessive trigger member 683 are connected by a connecting frame. The connecting frame and the connecting ring 911 are slidably matched. The snap-on pin 92 is uniformly slidably arranged on the inner periphery of the first gear 91 along the radial direction. A spring eight is connected between the snap-on pin 92 and the first gear 91. The spring eight always keeps the snap-on pin 92 pushing toward the center. The outer periphery of the rotating column 62 is provided with a snap-on pin 92 The second gear 93 is rotatably arranged on the inner wall of the mounting shell 5 through an auxiliary bracket, the second gear 93 is meshed with the first gear 91, and the second gear 93 is matched with the agitator 82 through a pulley assembly 94. When the over-trigger 683 is triggered, the connecting ring 911 is pulled, and the first gear 91 follows the connecting ring 911 to move so that the position of the locking pin 92 corresponds to the locking groove 621. Under the action of spring eight, the locking pin 92 is inserted into the locking groove 621 (at this time, it is in the detection state of the core sample end face, so the rotating column 62 rotates at a low speed, which will not affect the docking of the locking pin 92 with the locking groove 621). After that, the first gear 91 follows the rotating column 62 to move and rotate. Under the meshing action, the second gear 93 follows the first gear 91 to rotate. Under the action of the pulley assembly 94, the agitator 82 rotates.

[0043] During the actual slurry stirring process, the excessive trigger member 683 is compressed and displaced, and the moving excessive trigger member 683 pulls the connecting ring 911, and the first gear 91 follows the connecting ring 911 to move so that the position of the locking pin 92 corresponds to the locking groove 621, and under the action of spring eight, the locking pin 92 is inserted into the locking groove 621 (at this time, it is in the detection state of the core sample end face, so the rotating column 62 rotates at a low speed and will not affect the docking of the locking pin 92 and the locking groove 621). After that, the first gear 91 follows the rotating column 62 to move and rotate, and under the meshing action, the second gear 93 follows the first gear 91 to rotate, and under the action of the pulley assembly 94, the agitator 82 rotates.

[0044] Reference Fig. 9As shown, the present application is provided with a leveling module 10 to level the end surface of the core sample, and the leveling module 10 includes a cover body 101, an electric rotating bracket 102, a perfusion hole 103, and a flattening block 104. The cover body 101 is installed on the electric rotating bracket 102, and the electric rotating bracket 102 drives the cover body 101 to rotate and displace. The electric rotating bracket 102 is sleeved on the outer periphery of the bearing column 2, and the electric rotating bracket 102 is slidably arranged on the movable seat 4 through an elastic telescopic member. The side wall of the cover body 101 is provided with a perfusion hole 103. The injection hole 103 is connected to the storage shell 81 through a delivery hose. The slurry inside the storage shell 81 flows out of the injection hole 103 through the delivery hose, thereby transferring the slurry to the end face of the core sample. The flattening block 104 is slidably arranged in the cover body 101. A spring nine is connected between the flattening block 104 and the cover body 101. The spring nine plays a resetting role. The flattening block 104 slides relative to the cover body 101 to flatten the slurry on the end face and keep the slurry in a flat state to solidify, thereby completing the repair work.

[0045] During the actual leveling process, the movable seat 4 is moved so that the mounting shell 5 is away from the core sample (the cover body 101 also moves with the movable seat 4 and away from the core sample to avoid interference), and then the electric rotating bracket 102 drives the cover body 101 to rotate and displace, and the cover body 101 rotates to a position corresponding to the end face of the core sample, and then the slurry inside the storage shell 81 flows out from the injection hole 103 through the conveying hose to the end face of the core sample, and then the movable seat 4 is controlled to close to the core sample, and extrusion occurs between the detection head 1 65, the detection head 2 66 and the flattening block 104, and the detection head 1 65 and the detection head 2 66 are squeezed and reset, and then the flattening block 104 is squeezed to a state of tightly pressing the end face of the core sample, and this state is maintained waiting for the slurry to solidify.

[0046] The implementation principle of this embodiment is:

[0047] Step 1: clamping the concrete core sample on the clamping module 3;

[0048] Step 2: Operate the mounting shell 5 to close to the core sample;

[0049] Step 3: The detection module 6 gradually contacts the end surface of the core sample and is triggered. The triggered detection module 6 performs a flatness detection on the end surface of the core sample. There are two situations at this time:

[0050] A. If the end surface of the core sample is flat, no operation is performed;

[0051] B. The end surface of the core sample is not flat. There are two situations at this time. The specific situations are as follows:

[0052] b1. If the height difference of the end surface of the core sample is small, the polishing module 7 is triggered and the end surface of the core sample is polished flat;

[0053] b2. The height difference of the end face of the core sample is large, and the grinding module 7 is also triggered. However, at this time, the grinding module 7 stops working after grinding the end face of the core sample to a certain degree. After that, the linkage module 9 triggers the material preparation module 8 to stir the slurry for repair to prevent coagulation, and then the leveling module 10 performs a leveling operation on the end face of the core sample;

[0054] Step 4: Remove the core sample.
